Description
TECHNICAL FIELD
[0001] The present invention relates to a raised floor and, more
particularly, to a raised floor with improved structure, where the
internal walls, of a plurality of holes provided at the top of the
metal base are used as binding parts for being attached by the
adhesive of the adhesive layer in order to enhance the binding
ability of the adhesive layer for the metal base; and consequently
a hard material layer can be firmly attached to the metal base.
BACKGROUND
[0002] In workplaces where computers are commonly used, the
arrangement and wiring of different kinds of wires and cables (such
as Internet cables) are of great importance. In order to electrify
the computers or to connect the computers one with another, wires
and cables are necessarily required. However, with the increase of
the number of the computers or other computer-related equipments,
more wires and cables are required. Accordingly, the arrangement of
these wires and cables becomes more complicated and difficult.
Exposed wires and cables may not only easily become nuisances, but
also will hinder the walking of the staff in the workplaces.
Therefore, in a modernized office, it is a tendency to have floors
raised in order to provide room for locating the wires and the
cables. Besides, the number of the raised floors can be determined
elastically according to the size of the internal space of an
office.
[0003] In order to beautify the raised floors, conventionally, it
is common to add a layer of hard material (made of, for example,
stone, tiles, or wood) on a raised floor. A conventional raised
floor can be formed by means of combining two alloy steel plates
together. After the combination of two alloy steel plates is
complete, the external surfaces thereof are painted in order to
provide the raised floor with refined beauty. Finally, the layer of
hard material is attached to the raised floor via adhesives.
[0004] However, the biding ability of the adhesives used in the
conventional raised floor structure is often insufficient to fix
the layer of hard material onto the raised floor due to the poor
binding ability of the adhesive layer applied between a layer of
metal material and a layer of hard material. Since the raised floor
is made by metal material, the layer of hard material may easily
slide away from its original position relative to the below raised
floor. Moreover, as mentioned above, the raised floor is often
painted for the purpose of beauty. The painted surfaces of the
raised floor will further weaken the binding ability of the
adhesive.
SUMMARY OF THE DISCLOSURE
[0005] An object of the present invention is to provide a raised
floor with improved structure, where by using as binding parts the
internal walls of a plurality of holes provided at the top of the
metal base and having the adhesive of the adhesive layer attached
thereon, the binding ability of the adhesive layer can be enhanced
so as to make a hard material layer more firmly attached to the
metal base.
[0006] In order to achieve above object, the present invention
provides a raised floor with-improved structure comprising a metal
base, an adhesive layer, and a hard material layer. The metal base
is provided with a space therein and having a top and a bottom. The
top of the metal base is provided with a plurality of holes and the
internal wall of each hole is a binding part, while the bottom
thereof is provided with a plurality of upward recessed parts. The
adhesive layer is coated on the top of the metal base. The hard
material layer is adhered to the adhesive layer. After the hard
material layer is adhered to the adhesive layer, part of the
adhesive in the adhesive layer is pressed into the holes and
consequently attaches onto the binding parts.
[0007] In practice, each binding part preferably includes an
extension part extending toward the space in the metal base.
Consequently, the extension part can be covered with the adhesive
in the adhesive layer.
[0008] In practice, the extension part of each binding part
preferably forms a bag having a T-shape internal space for
receiving the adhesive in the adhesive layer.
[0009] In practice, the top of each recessed part is preferably in
contact with the top of the metal base. Besides, at least one hole
is preferably located between any two locations at which the tops
of recessed parts are in contact with the top of the metal
base.

DETAILED DESCRIPTION
[0018] Please refer to FIGS. 1-5A showing a first embodiment of a
raised floor with improved structure according to the present
invention. The raised floor with improved structure according to
the present invention comprises a metal base 1, an adhesive layer
2, and a hard material layer 3.
[0019] In this embodiment, the metal base 1 is formed by piling a
upper metal plate 10 on a lower metal plate 12 and then pressing
and fixing the peripheries of the upper and lower metal plates 10,
12. After the metal base 1 is formed, an internal space 14 is
defined therein. Besides, the metal base also can be formed in one
piece without falling outside the scope and departing from the
spirit of the present invention.
[0020] The metal base 1 has a top 16 and a bottom 18. The top 16 is
provided with a plurality of holes 160 and the inner wall of each
hole 160 is a binding part 162. The bottom 18 has a plurality of
upward recessed parts 182.
[0021] Moreover, in this embodiment, the top of each recessed part
182 is in contact with the top 16 of the metal base 1. In other
words, a plurality of contact locations 4 is formed on the top 16
of the metal base 1. Among the holes 160 at least one is located
between any two contact locations 4 at which the tops of recessed
parts are in contact with the top 16 of the metal base 1. However,
above arrangement of the holes in this embodiment is only for
illustrative purpose and the holes also can be located at other
locations on the top of the metal base.
[0022] The adhesive layer 2 is coated on the top 16 of the metal
base 1. In practice, the adhesive layer 2 is made by AB glues.
Moreover, the hard material layer 4 can be made by stones, tiles,
wood, or other hard material.
[0023] Please refer to FIGS. 4 and 5A. When being placed on and
adhered to the adhesive layer 2, the hard material layer 3 can
exert a force to press part of the adhesive of the adhesive layer 2
into the holes 160 provided on the top 16 of the metal base 1 and
have the adhesive attached onto the binding parts 162.
[0024] Because part of the adhesive of the adhesive layer 2 is
attached onto the binding parts 162 in the holes 160, the adhesive
layer 2 can be in firmer connection with the metal base 1 when the
adhesive is solidified. Consequently, it is effective to enhance
the binding force between the hard material layer 3 and the metal
base 1 so as to overcome the conventional shortcomings where the
hard material layer may easily slides away from its original
location because of insufficient binding ability.
[0025] Please refer to FIGS. 5B and 5C respectively showing a
second and a third embodiment of a raised floor with improved
structure according to the present invention. Compared with the
first embodiment, the critical difference of the second and the
third embodiments is the structure of the binding parts.
[0026] As shown in FIG. 5B, in the second embodiment, each binding
part 162 further includes an extension part 164. The extension part
164 extends from the inner wall of the hole into the space 14 of
the metal base 1. When the hard material layer 3 is placed on the
adhesive layer 2, part of the adhesive can further cover the
extension parts 164. Thereby, the binding ability between the
adhesive layer 2 and the metal base 1 can be enhanced so as to
strengthen the connection between the metal base 1 and the hard
material layer 3.
[0027] Please refer to FIG. 5C. In the third embodiment, the
extension part of each binding part further forms a bag 166 having
a T-shape internal space. By this modification, when the hard
material layer 3 is placed on the adhesive layer 2, the adhesive
pressed into the holes can be further attached onto the inner walls
of the bags 166. Or, the bags 166 may even be filled fully with
adhesive. By this way, the binding ability between the adhesive
layer 2 and the metal base 1 can be further enhanced so as to
strengthen the connection between the metal base 1 and the hard
material layer 3.
[0028] As disclosed in above descriptions and attached drawings,
the present invention provides a raised floor with improved
structure, wherein the internal walls of a plurality of holes
provided at the top of the metal base are used as binding parts for
being attached by the adhesive of the adhesive layer in order to
enhance the binding ability between the adhesive layer and the
metal base so as to have a hard material layer firmly attached to
the metal base. It is new and can be put into industrial use.
[0029] Although the embodiments of the present invention have been
described in detail, many modifications and variations may be made
by those skilled in the art from the teachings disclosed
hereinabove. Therefore, it should be understood that any
modification and variation equivalent to the spirit of the present
invention be regarded to fall into the scope defined by the
appended claims.
