[0002] The present invention relates to a novel assembled slab
steel-wood composite joint, and belongs to the field of building
construction.
BACKGROUND
[0003] With the gradual transformation of the development mode of
the construction industry, quality and efficiency improvement,
energy conservation and emission reduction have become inevitable
construction requirements of production in the construction
industry. Compared with traditional buildings, prefabricated
buildings can minimize engineering problems caused by poor
engineering quality, thus effectively guaranteeing the engineering
quality and construction safety.

disadvantages that materials are difficult to obtain, modular
connection and construction cannot be realized, and the
construction speed is low; and more importantly, welding has to be
conducted to improve the strength of steel connection joints, and
the construction quality cannot be guaranteed. Moreover, the weight
of the whole joints is large, and the bearing capacity of the
joints is relatively low.
[0006] To sum up, the building joint techniques in the prior art
cannot be widely popularized in the industry and are low in degree
of standardization. In view of this, this patent application is put
forward.

of joint destruction are fulfilled by means of steel-based
mechanical connection.

sleeve of the steel-wood composite column is greatly improved, the
horizontal steel bars arranged in the cross-shaped outer wood
column can greatly improve the stress performance and seismic
performance, and the bearing capacity per unit mass of the
steel-wood composite column is higher than that of pure wood
structures. The square blocks of the cross-shaped steel-wood

the adjacent wood slabs 3 are formed in the joints; and sixth bolt
holes 16 used for fixed connection are correspondingly formed in
portions, to be connected to the connecting parts 10, of the
insertion heads 20 of the wood slabs 3.
[0050] Each connecting assembly 4 comprises a threaded sleeve 9
having two ends respectively connected to the horizontal steel bars
123 and the vertical protruding steel bars 456, and one connecting
part 10, wherein the threaded sleeve 9 is preferably of a straight
sleeve structure, the connecting part 10 comprises a C-shaped left
hollowed-out cover plate 18 and a C-shaped right hollowed-out cover
plate 19, and the bottoms of the left hollowed-out cover plate 18
and the right hollowed-out cover plate 19 are horizontally
connected and are assembled and fixed together by means of bolt
backing plates 17 and bottom bolts; second bolt holes 12 and fourth
bolt holes 14 used for fixed connection are respectively and
correspondingly formed in portions, to be connected to the
corresponding square block of the outer square wood column 5, of
the horizontal surface and the vertical surface of the connecting
part 10; first bolt holes 11 and third bolt holes 13 used for fixed
connection are respectively and correspondingly formed in portions,
to be connected to the corresponding square wood beam 2, of the
horizontal surface and the vertical surface of the connecting part
10; and sixth bolt holes 16 used for fixed connection are
correspondingly formed in portions, to be connected to the
insertion heads 20 of the corresponding wood slab 3, of the
connecting part 10.
[0051] On the basis of the structural design of the assembled slab
steel-wood composite joint, an assembly method of the composite
joint is implemented through the following steps:
[0052] Step 1): the steel sleeve 7 is disposed in the outer square
wood column 5, the horizontal steel bars 123 are anchored, the
inner wood column 8 is filled in the steel sleeve 7, and the
vertical steel bars 6 are inserted into the inner wood column
8;
[0053] Step 2): the vertical protruding steel bars 456 are inserted
into the square wood beams 2 and protrude out of the square wood
beams 2;
[0054] Step 3): after the steel-wood composite column 1 and the
square wood beams 2 are assembled, protruding parts of the steel
bars are connected by means of the threaded sleeves 9;
[0055] Step 4): the left hollowed-out cover plates 18 and the right
hollowed-out cover plates 19 are assembled by means of the bolt
backing plates 17 to form the connecting parts 10, and the
connecting parts 10 are horizontally connected and fastened with
the steel-wood composite column 1 and the square wood beams 2 by
means of bolt holes and bolts at both ends;
[0056] Step 5): the L-shaped slabs 21 are disposed at the tops of
the square blocks and the connecting parts 10 and are connected
around the steel-wood composite column, and the L-shaped slabs 21
are horizontally and fixedly connected to the square wood beams 2
and the connecting parts 10 through bolts; and
[0057] Step 6): the square slabs 22 are connected in an inserted
manner around the L-shaped slabs 21, and are horizontally and
fixedly connected to the L-shaped slabs 21 and the square wood
beams 2 through bolts.
[0058] Compared with steel structures in the prior art, the
steel-wood composite structure formed by steel and wood in this
embodiment has better stress performance per unit mass and has good
seismic performance under the effect of an earthquake due to the
fact that wood has certain tenacity. Compared with wood structures
in the prior art, the column in this embodiment is of a steel-wood
structure, the steel sleeve and the vertical steel bars are
additionally arranged in the cross-shaped column, so that the
stress performance per unit mass of the structure is improved, and
the overall life is prolonged; steel bars are arranged in the
square wood beams to improve the tensile strength of the wood
beams, so that the shear resistance of the wood beams is better
than that of I-beams; and the whole joint is assembled by means of
mechanical connection, so that the components can be changed more
easily under the effect of an earthquake. Components can be
customized in advance, prefabricated construction on the
construction field is realized, quality problems caused by welding
of steel components are avoided, the construction period is
shortened, and the construction cost is reduced.
[0059] Similar technical solutions can be derived in combination
with the accompanying drawings and the solution described above.
All solutions obtained without departing from the structure of the
present invention should also fall within the protection scope of
the present application.
