thin wall steel profiles and concrete enclosing the same, in which
the main surfaces of two longitudinal cold bend thin wall steel
profiles (51, 52, 91, 92) included in each longitudinal cold bend
thin wall steel profile keel are parallel to the main surface of
the concrete slab, the two longitudinal cold bend thin wall steel
profiles (51, 52, 91, 92) are spaced apart and opposite each other
along a direction perpendicular to the main surface of the concrete
slab, so that a space (200) for the concrete to flow through when
it is poured is left between the two longitudinal cold bend thin
wall steel profiles. Also provided is a construction method for
building a concrete slab structural member. The structural member
has avoided or reduced as much as possible the problem of the
flowing of concrete being hindered when it is poured, due to the
placement of the cold bend thin wall steel profiles perpendicular
to the concrete slab, which exists in the concrete structural
member with cold bend thin wall steel profiles in the prior art,
and the problem of cold bridges that is created by the
perpendicularly placed cold bend thin wall steel profiles in the
concrete formed after pouring the same.

Description
FIELD OF THE INVENTION
[0001] The present invention belongs to the field of building
structural members and construction methods and in particular,
relates to a concrete slab structural member and a construction
method for pouring the concrete slab.
DESCRIPTION OF THE PRIOR ART
[0002] There are concrete slab structural members with cold bend
thin wall steel profiles as the frame according to the prior art.
According to the prior art, the frame of cold bend thin wall steel
profiles comprises a plurality of vertical cold bend thin wall
steel profiles spaced apart laterally and arranged in parallel. The
main surfaces of the cold bend thin wall steel profiles are
perpendicular to the main surface of the concrete slab structural
member. As such, a space is formed between every two adjacent cold
bend thin wall steel profiles, which results in some problems. For
example: 1) when concrete is poured between the external concrete
form and the internal concrete form, the flowing of concrete is
hindered by the cold bend thin wall steel profiles, the concrete
pouring efficiency is low, and the compactness and homogeneity of
the poured concrete are affected; 2) The main surfaces of the cold
bend thin wall steel profiles are perpendicular to the main surface
of the concrete slab structural member, such that the cold bend
thin wall steel profiles extend in the direction from indoor to
outdoor and a cold bridge is formed between the indoor and the
outdoor, which affects the thermal insulation effect of the wall
panels.
SUMMARY OF THE INVENTION
[0003] One object of the present invention is to provide a new
concrete slab structural member that combines cold bend thin wall
steel profiles and concrete, which can avoid or reduce as much as
possible the problem of the flowing of concrete being hindered when
it is poured, due to the placement of the main surfaces of the cold
bend thin wall steel profiles perpendicular to the main surface of
the concrete slab structural member, which exists in the concrete
structural member with cold bend thin wall steel profiles in the
prior art. The other object of the present invention is to provide
a to solve the problem of cold bridge that is created by the
perpendicularly placed cold bend thin wall steel profiles in the
concrete formed after pouring the same.
[0004] The technologies according to the present invention are as
follows:
[0005] First basic technology:
[0006] A concrete slab structural member, comprising: a frame of
cold bend thin wall steel profiles; concrete that encloses the
frame of cold bend thin wall steel profiles; the frame of cold bend
thin wall steel profiles comprises a plurality of longitudinal cold
bend thin wall steel profile keels (5, 9) that are spaced apart
along the lateral extension direction of the main surface of the
concrete slab structural member and placed in parallel to one
another; wherein, each longitudinal cold bend thin wall steel
profile keel comprises two longitudinal cold bend thin wall steel
profiles (51, 52, 91, 92), the main surfaces of two longitudinal
cold bend thin wall steel profiles are parallel to the main surface
of the concrete slab structural member, the two longitudinal cold
bend thin wall steel profiles are spaced apart and opposite each
other along a direction perpendicular to the main surface of the
concrete slab structural member, so that a space (200) for the
concrete to flow through when it is poured is left between the two
longitudinal cold bend thin wall steel profiles. The space left
between the two longitudinal cold bend thin wall steel profiles is
filled with concrete.
[0007] The present invention has the following advantageous
effects:
[0008] In the concrete slab structural member of the present
invention, each longitudinal cold bend thin wall steel profile keel
comprises two longitudinal cold bend thin wall steel profiles, the
main surfaces of the two longitudinal cold bend thin wall steel
profiles are parallel to the main surface of the concrete slab
structural member, the two longitudinal cold bend thin wall steel
profiles are spaced apart and opposite each other along a direction
perpendicular to the main surface of the concrete slab structural
member, so that a space for the concrete to flow through when it is
poured is left between the two longitudinal cold bend thin wall
steel profiles. This avoids the problem created by the placement of
the main surfaces of the cold bend thin wall steel profiles
perpendicular to the main surface of the concrete slab structural
member according to the prior art. 1) Regarding the problem 1)
mentioned in the section of Description of the Prior Art, since the
longitudinal cold bend thin wall steel profiles of the present
invention extend in the direction parallel to the main surface of
the concrete slab structural member, they will not cause the same
big hindrance as the prior art to the flowing of the poured
concrete along the lateral extension direction of the concrete slab
and along the concrete forms, and consequently the concrete can
smoothly flow in the direction of the main surfaces of thin wall
steel profiles. This can improve the pouring efficiency, and
improve the compactness and homogeneity of the concrete that has
been poured into the space between the internal and external
concrete forms; regarding the problem 2) mentioned in the section
of Description of the Prior Art, the cold bend thin wall steel
profiles of the present invention extend in the direction parallel
to the main surface of the concrete slab structural member
(perpendicular to the direction from indoor to outdoor), which
avoids the formation of a cold bridge between the indoor and the
outdoor. Another aspect of the present invention is to solve the
cold bridge cold bridge problem that is created by the
perpendicularly placed cold bend thin wall steel profiles to the
main surface of the concrete slab in the concrete formed after
pouring the same in the prior art.
[0009] Relative to the cold bend thin wall steel profile and
concrete structure according to the prior art, meanwhile, the cold
bend thin wall steel profile and concrete structure according to
the present invention further has other advantages. Damages to a
concrete slab due to stress take place primarily in areas proximate
to the two external main surfaces of the slab, while reinforcing
bars are not needed in the middle of the slab along the direction
perpendicular to the main surfaces of the slab. In the structure
according to the prior art, however, the cold bend thin wall steel
profiles are placed perpendicular to the main surfaces of the
concrete slab. As a result, the portion of the cold bend thin wall
steel profiles at the middle of the slab cannot fully play their
role in bearing loads, leading to the waste of steel. While in the
present invention, each longitudinal cold bend thin wall steel
profile keel comprises two longitudinal cold bend thin wall steel
profiles, the main surfaces of the two longitudinal cold bend thin
wall steel profiles are parallel to the main surface of the
concrete slab structural member, the two longitudinal cold bend
thin wall steel profiles are spaced apart and opposite each other
along a direction perpendicular to the main surface of the concrete
slab structural member, so that a space is left between the two
longitudinal cold bend thin wall steel profiles. Therefore, there
actually is no reinforcing bar in the middle of the concrete slab,
and the steel is mostly concentrated at the two surfaces of the
slab that need reinforcing bars the most, which significantly
improves the utilization of steel. Relative to the cold bend thin
wall steel profile structure in the prior art, it saves steel.
[0010] In the present invention, moreover, the main surfaces of the
two longitudinal cold bend thin wall steel profiles contained in
each longitudinal cold bend thin wall steel profile keel are
parallel to the main surface of the concrete slab structural
member, and the two longitudinal cold bend thin wall steel profiles
are spaced apart and opposite each other along a direction
perpendicular to the main surface of the concrete slab structural
member, which forms a more stable self-support and can reduce or
eliminate additional supports to the concrete forms.
[0011] When modular concrete forms are combined with the frame
structure of cold bend thin wall steel profiles, moreover, a
complete industrialized building system will be formed. This system
relates to building design and building structure, and moreover,
relates to building construction. With an extensive application
range, this system has a lot of advantages. Specific examples are
as follows:
[0012] 1. When modular concrete forms are combined with the frame
structure of cold bend thin wall steel profiles according to the
present invention to replace thread steel with cold bend thin wall
steel profiles, the stability of temporary structure and accuracy
of sizes are significantly improved without increasing the total
steel consumption, such that the construction process is more
convenient, rapid and reliable, and the use of temporary support is
effectively reduced.
[0013] 2. Due to the change of the construction method, the
workload of field construction is greatly reduced (by eliminating
the existing steel bar bundling operation, simplifying the concrete
form support operation or eliminating the concrete form support),
thereby saving labor, reducing work intensity, and shortening the
construction period. As estimated, the application of the new
industrialized building assembly technique formed by the
combination of the cold bend thin wall steel profile frame and
concrete structure according to the present invention and the
modular concrete forms can save labor by 35%.about.50% and shorten
the construction period by more than 40%.
[0014] 3. When permanent concrete forms are used in the cold bend
thin wall steel profile frame and concrete structure according to
the present invention, the effect of saving work hours and
shortening construction period is further enhanced.
[0015] 4. When the slab of the cold bend thin wall steel profile
frame and concrete structure according to the present invention is
formed, a composite steel-concrete construction can be formed. The
composite steel-concrete construction is one of the structures that
are currently recognized to have the most excellent
anti-earthquake, lasting and fire-resistant properties. Its
anti-earthquake property is far better than the masonry structure,
its fire resistant property and lasting property are far better
than the steel structure, and its anti-earthquake and structural
ductility are far better than those of the reinforced concrete
structure according to the prior art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0043] In the following description, identical parts have the same
names and use the same legends. Corresponding parts have the
corresponding names and use the corresponding legends.
[0044] Preferred embodiments of the concrete slab structural member
according to the present invention
[0045] Refer to FIGS. 1-4 below. These figures illustratively show
a concrete slab structural member according to a preferred
embodiment of the present invention. In these figures, the wall
slab structural member in the preferred embodiment of said concrete
slab structural member is illustrated in detail. At the same time,
the floor slab or roof slab structural member is also illustrated
appropriately. It should be understood that those skilled in the
art can understand after reading the Description that the structure
of the floor slab or roof slab structural member is very similar to
that of the wall slab, which only omits the concrete form at one
side of the frame of cold bend thin wall steel profiles relative to
the wall slab, namely, the concrete form is not needed for the top
side of the frame of cold bend thin wall steel profiles, while for
the concrete form at another side of the frame of cold bend thin
wall steel profiles, namely the concrete form at the bottom side
(or external side) of the frame of cold bend thin wall steel
profiles, concrete form vertical support may be provided as
needed.
[0046] The concrete wall slab structural member shown in FIGS. 1-4
is in a construction site state. Said wall slab structural member
comprises a frame of cold bend thin wall steel profiles as
reinforcing bars, concrete forms and concrete form keels. To
clearly illustrate the structure, the concrete that wraps said
frame of cold bend thin wall steel profiles is not shown (or it
could be understood as a state in which concrete is not
poured).
[0047] As shown in the figures, the frame of cold bend thin wall
steel profiles comprises a plurality of longitudinal cold bend thin
wall steel profile keels 5 that are spaced apart along the lateral
extension direction (i.e. the direction perpendicular to the paper
in FIG. 1) of the main surface (i.e. the surface running through
the concrete wall slab and perpendicular to the paper in FIG. 1 and
perpendicular to the top surface of the starting platform 113 in
FIG. 1) of the concrete wall slab structural member and placed in
parallel to one another. Each longitudinal cold bend thin wall
steel profile keel comprises two longitudinal cold bend thin wall
steel profiles 51, 52. The main surface of the vertical cold bend
thin wall steel profile 51 or 52 (i.e. the surface running through
the center of said vertical cold bend thin wall steel profile 51 or
52 and perpendicular to the paper in FIG. 1 and perpendicular to
the top surface of the starting platform 113 in FIG. 1) is parallel
to the main surface of the concrete wall slab structural member.
The two longitudinal cold bend thin wall steel profiles 51, 52 are
spaced apart and opposite each other along a direction
perpendicular to the main surface of the concrete wall slab
structural member (i.e. the direction parallel to the paper in FIG.
1, and the direction of the oblique axis shown in FIG. 2), so that
a space 200 for the concrete to flow through when it is poured is
left between the two longitudinal cold bend thin wall steel
profiles. When the concrete wall slab is poured and formed, the
space left between the two longitudinal cold bend thin wall steel
profiles is filled with concrete.
[0048] At positions spaced apart along the longitudinal direction
of the cold bend thin wall steel profiles, the top and bottom two
positions in FIG. 2, the two longitudinal cold bend thin wall steel
profiles are, for example, connected through connection steel
plates 61, 62 via welding or bolt connection so as to fixedly
connect the two vertical cold bend thin wall steel profiles.
[0049] Each of the vertical cold bend thin wall steel profiles 51,
52 has a plurality of through holes 191, 192 on the rolling keel
edge distributed along the lengthwise direction thereon for
concrete to flow through when it is poured, and the connection
steel plates 61, 62 have holes 193, 194 on the rolling edge for
concrete to flow through when it is poured. The functions of the
holes on the rolling edge include a. to facilitate the flowing of
concrete and improve the concrete pouring efficiency, and b. to
improve the rigidity, strength and stability of steel profile
parts.
[0050] As shown in FIGS. 1, 3 and 4, a plurality of vertical cold
bend thin wall steel profile keels are connected with a plurality
of lateral connection cold bend thin wall steel profile keels
distributed along the longitudinal direction of the vertical cold
bend thin wall steel profile keels (e.g. through self-tapping
screws 118 or screws), and connected with diagonal support cold
bend thin wall steel profile keels (e.g. through self-tapping
screws 118 or screws), thereby forming a stable overall rigid
structure. Each lateral connection cold bend thin wall steel
profile keel comprises lateral cold bend thin wall steel profiles
81, 82. Each diagonal support cold bend thin wall steel profile
keel comprises diagonal cold bend thin wall steel profiles 31,
32.
[0051] As shown in FIG. 1, the concrete wall slab structural member
comprises a starting platform 113 disposed at the bottom as the
base. A starting sleeve 4 is fixed on the starting platform 113,
and the starting slab 112 of the starting sleeve 4 is fixed on the
starting platform 113 by means of an expansion bolt 91. The
starting sleeve 4 has starting vertical cold bend thin wall steel
profile keels 41, 42 that project upwardly. Vertical cold bend thin
wall steel profiles 51, 52 fit over said starting vertical cold
bend thin wall steel profile keels 41, 42 and are fixedly connected
therewith (e.g. by means of bolts or welding).
[0052] As shown in FIGS. 1, 3 and 4, the concrete wall slab
structural member further comprises an external concrete form 131
and an internal concrete form 132 when in the construction site.
The external concrete form 131 is disposed at one side of said
frame of cold bend thin wall steel profiles, and the internal
concrete form 132 is disposed at another side of said frame of cold
bend thin wall steel profiles. Of course, it should be understood
that when the concrete is poured and formed, if regular detachable
concrete forms are used, the concrete forms will be detached and
the ultimately hardened and formed wall slab does not have concrete
forms; if permanent concrete forms are used, the permanent concrete
forms will become a part of the ultimately formed wall slab.
[0053] As clearly shown in FIGS. 1 and 2, the holes 191, 192 on the
rolling keel edge of the two vertical cold bend thin wall steel
profiles are opposite each other, and the running direction of said
holes on the rolling keel edge is perpendicular to the main surface
of said concrete slab structural member. The tension connection
bolt 111 runs through some (determined according to the amount of
tension connection points) of the holes 191, 192 on the rolling
keel edge. The external tension sleeve 171 is disposed between said
external concrete form 131 and the vertical cold bend thin wall
steel profile 51 located at the external side. The internal tension
sleeve 172 is disposed between said internal concrete form 132 and
the vertical cold bend thin wall steel profile 52 located at the
internal side. The two tension sleeves 171 and 172 are connected
through threads onto two ends of the tension connection bolt 111.
An external vertical concrete form keel 121 and an external lateral
concrete form keel 141 are disposed between said external tension
bolt 161 and said external concrete form 131 for providing support
to the external concrete form, and an internal vertical concrete
form keel 122 and an internal lateral concrete form keel 142 are
disposed between said internal tension bolt 162 and said internal
concrete form 132 for providing support to the internal concrete
form. The external tension bolt 161 runs through an external gasket
151, the external lateral concrete form keel 141, the external
vertical concrete form keel 121 and the external concrete form 131
sequentially to connect with said external tension sleeve 171
through threads so as to fixedly connect the external concrete form
with the vertical cold bend thin wall steel profile keel and such
that it is supported sufficiently and becomes a stable structure.
The internal tension bolt 162 runs through an internal gasket 152,
the internal lateral concrete form keel 142, the internal vertical
concrete form keel 122 and the internal concrete form 132
sequentially to connect with said internal tension sleeve 172
through threads so as to fixedly connect the internal concrete form
with the vertical cold bend thin wall steel profile keel and such
that it is supported sufficiently and becomes a stable
structure.
[0054] As shown in FIGS. 1 and 2, both of the two longitudinal cold
bend thin wall steel profiles included in each longitudinal cold
bend thin wall steel profile keel are C shaped steel profiles, and
are placed in such a way that the grooves of the two steel profiles
are opposite each other. It should be understood that both the
external concrete form and the internal concrete form could be
modular concrete forms.
[0055] A space is left between the external concrete form, the
internal concrete form and the vertical cold bend thin wall steel
profiles 51, 52. When it is poured, the concrete is between the
external concrete form and the internal concrete form, and covers
said frame of cold bend thin wall steel profiles.

[0059] As shown in the figures, the construction method of the
poured concrete wall slab of said preferred embodiments of the
present invention comprises the following steps:
[0060] A step of installing a frame of thin wall steel profiles,
wherein a plurality of vertical cold bend thin wall steel profile

[0063] A step of pouring concrete, wherein concrete is poured

[0064] The step of installing the frame of thin wall steel profiles
comprises: preparing a starting platform 113 at the bottom, fixing
a starting sleeve 4 that comprises a starting slab 112 and starting
vertical cold bend thin wall steel profile keels 41, 42 on said
starting platform, and fixedly connecting said vertical cold bend
thin wall steel profiles 51, 52 with said starting vertical cold
bend thin wall steel profile keels 41, 42; a step of connecting
said two vertical cold bend thin wall steel profiles, the holes
191, 192 on the rolling keel edge of the two vertical cold bend
thin wall steel profiles are made to be opposite each other such
that the running direction of said holes on the rolling keel edge
is perpendicular to the main surface of said concrete wall slab,
and connection steel plates 61, 62 are used to fixedly connect the
two vertical cold bend thin wall steel profiles at positions spaced
apart along the vertical direction of the cold bend thin wall steel
profiles; using a lateral connection cold bend thin wall steel
profile keel that comprises lateral cold bend thin wall steel
profiles 81, 82 to connect a plurality of vertical cold bend thin
wall steel profile keels placed in parallel, and connecting a
diagonal support cold bend thin wall steel profile keel that

the vertical cold bend thin wall steel profile keel to form a
stable overall rigid structure; running the tension connection bolt
111 through some of the holes 191, 192 on the rolling keel edge
such that two ends of said tension connection bolt 111 run through
said holes on the rolling keel edge, respectively, to be connected
with said external tension sleeve and said internal tension sleeve
via threads.
[0065] When said external concrete form is installed, a space is
left between said external concrete form and the vertical cold bend
thin wall steel profile 51 located at the external side, when said
internal concrete form is installed, a space is left between said
internal concrete form and the vertical cold bend thin wall steel
profile 52 located at the internal side, and when concrete is
poured, said concrete fills up the space between said external
concrete form and said internal concrete form and covers said frame
of cold bend thin wall steel profiles.
[0066] Disposing an external vertical concrete form keel 121 and an
external lateral concrete form keel 141 between said external
tension bolt 161 and said external concrete form 131 for providing
support to the external concrete form, and disposing an internal
vertical concrete form keel 122 and an internal lateral concrete
form keel 142 between said internal tension bolt 162 and said
internal concrete form 132 for providing support to the internal
concrete form.

sleeve 171, running said external tension bolt through an external
gasket 151, the external lateral concrete form keel, the external

keel edge and the holes on the rolling keel edge of said connection
steel plates. The flowing obstruction is very low, the flowing is
very smooth, the pouring efficiency is relatively high, work time
and energy consumption are saved, and the compactness and
homogeneity of the formed concrete are better.

steel profile keel may be fixedly connected through longitudinal
connection thin wall steel profiles 71, 72 included in the
longitudinal steel profile connection keel 7, such that the
longitudinal (or vertical) length (or height) of the steel profile
keel may reach the length (or height) desired in engineering.

art may understand that the construction method for the structure
and slab of frame of thin wall steel profiles according to the
present invention may similarly be used in the pouring of floor
slabs. It is just that concrete forms are not disposed on the top
side of the frame when the floor slab is poured. Instead, regular
detachable concrete forms are fixedly connected to the bottom side
(external side) of the frame of thin wall steel profiles, and then
concrete is poured from above. When the frame of thin wall steel
profiles according to the present invention is used on building
roof slabs, it can similarly achieve the effect of reducing or
eliminating the cold bridge.
[0073] With respect to the above specific technologies that use the
frame of thin wall steel profiles of the present invention to take
the place of steel bars, those skilled in the art may employ
specific flows according to practical needs of a project to make

non-standard concrete forms, and determines hole positions of the
tension bolts;
[0076] 3. When the foundation construction is completed, construct
a starting platform or use the foundation as the starting platform.
It is required that the sizes be accurate and the entire
circumference be at the same elevation. Begin to continuously fix
starting sleeves according to the design requirements;
[0077] 4. Perform the construction of vertical keels, fit the

[0080] 7. Repeat Steps 5 and 6 to the position of floor slabs, the
modular internal concrete forms intersect with the bottom concrete
forms of the floor slab (optionally detachable modular concrete
forms may be used), and construct a reliable support, continue
upwardly to install one to two pieces of the modular external
concrete forms and connect with the raised vertical keels;
[0081] 8. Conduct the construction of the frame of thin wall steel
profiles and concrete forms (including the external concrete forms
and internal concrete forms) alternately. Typically, the vertical
keels are 90 cm above the floor surface and function as a temporary
fence. When the installation of floor thin wall steel profiles is
completed, pour concrete for the lower level walls and the floor.
Make sure to pour in rounds with each pouring at about 0.5 m
high;
[0082] 9. Repeat Steps 5.about.8 to the roof.
