The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be understood as imposing any limitation on the scope of the present invention.

Example (b):

referring to fig. 1 to 4, the present embodiment describes an assembled composite floor slab, which mainly includes a corrugated profiled bottom plate 1, a structural mesh 2, a cast-in-place layer 3 and a decorative layer 4. The corrugated compression base plates 1 are used as floor slabs and are arranged between beams or columns of the fabricated building and laid side by side, and two adjacent corrugated compression base plates 1 can be connected and fixed to form a whole to form a bearing structure of the floor slab.

The corrugated profiled bottom plate 1 has two modes, one mode is that a conventional single plate is continuously bent to form a corrugated plate, the size of the corrugated profiled bottom plate 1 formed after the single plate is continuously bent is determined according to the area size of a floor, and one or more corrugated profiled bottom plates are arranged between beams or columns.

Referring to fig. 3, another corrugated profiled bottom plate 1 is a corrugated profiled steel sheet, which is emphasized in this embodiment, the corrugated profiled bottom plate 1 includes a trapezoidal frustum 11 without a bottom edge structure, bottom portions of two side edges of the trapezoidal frustum 11 extend outward to form a first transverse plate 12, an end portion of the first transverse plate 12 extends upward to form a support plate 13, and a top portion of the support plate 13 extends toward the trapezoidal frustum 11 to form a second transverse plate 14. The first horizontal plate 12 is a wave trough of the corrugated profiled bottom plate 1, and the top surface of the trapezoidal frustum pyramid 11 is a wave crest of the corrugated profiled bottom plate 1.

In the above two embodiments of the corrugated profiled bottom plate 1, the wave crest of the first corrugated profiled bottom plate 1 is implemented as a plane, and the means can be realized by a die during cold rolling, so that the subsequent upper layer structure is better constructed, the wave trough is not required, and the wave trough can be a plane or a conventional arc-shaped surface; in the second wave-shaped profiled bottom plate 1, the wave crest is formed as the top plane of the trapezoidal terrace 11 due to the structure of the trapezoidal terrace 11, and the first horizontal plate 12 is formed as the valley of the wave-shaped profiled bottom plate 1.

The present embodiment is described in detail with reference to the second implementation structure of the corrugated profiled bottom plate 1, in practical construction, the first horizontal plate 12 is preferably implemented as a horizontal plate, which is good for visual aesthetics, but it does not mean that it has a certain slope or angle to achieve the purpose of the present embodiment, and it should be protected in the present technical solution.

Similarly, the supporting plate 13 is a part of the corrugated structure of the corrugated profiled bottom plate 1 on the one hand, and on the other hand, is also formed integrally with the trapezoidal prism table 11 for bearing force, and is preferably implemented as a vertical plate for bearing force conveniently, but it does not mean that the supporting plate has a certain inclination or angle to achieve the purpose of the present embodiment, and it should be protected in the present technical solution.

Further, the second horizontal plate 14 also assumes the position of the wave crest in the plurality of corrugated press-molded bottom plates 1, and therefore its elevation is flush with the elevation of the top surface of the trapezoidal terrace 11.

The structural mesh 2 is preferably a steel wire mesh or a steel bar mesh, which has flexibility to facilitate rolling, transportation, laying and installation.

Referring to fig. 4, the structural net 2 is generally applied in combination with the cast-in-place layer 3, specifically, the structural net 2 is laid on the corrugated profiled bottom plate 1, and may be fixedly connected to the corrugated profiled bottom plate 1 or may be laid simply, fig. 4 only shows the structural positions of the structural net 2 and the corrugated profiled bottom plate 1, the cast-in-place layer 3 needs to be expressed in combination with fig. 1, and the reason why the cast-in-place layer 3 and the decoration layer 4 are not expressed in fig. 4 is that it is unclear to prevent the random expression of lines.

When fixedly connected, the structural net 2 can be welded on the top surface of the corrugated profiled bottom plate 1, the cast-in-place layer 3 is poured in the structural net 2 and is bonded with the structural net 2 to form a combined layer, and the structural net 2 can be covered and the leveling effect is further achieved for facilitating the installation of the subsequent decorative layer 4.

When the structural net 2 is welded to the corrugated profiled bottom plate 1, the cast-in-place layer 3 sets the structural form of the structural net 2, the structural net 2 serves as an internal structural reinforcement of the cast-in-place layer 3, the two are bonded to form a bonding layer, the bonding layer serves as an upper chord compression layer of the corrugated profiled bottom plate 1, a combined effect is formed together with the corrugated profiled bottom plate 1, the vertical rigidity is greatly improved relative to the corrugated profiled bottom plate 1, and compared with the traditional wet method, the method has the advantages that the self weight is large due to the fact that concrete is poured into troughs, and the implementation mode can reduce the self weight.

The cast-in-place layer 3 is poured in the structural net 2, only a small amount of cast-in-place concrete is allowed to leak into the wave trough when pouring, the cast-in-place layer 3 is preferably fine aggregate concrete, the fine aggregate concrete is poured and bonded to the structural net 2, and meshes of the structural net 2 are beneficial to combination of the fine aggregate concrete and can prevent slurry leakage.

In order to further increase the shearing resistance of the corrugated profiled bottom plate 1, a plurality of shearing resistant keys 5 are arranged on the wave crests of the corrugated profiled bottom plate 1 at intervals along the depth direction. The shear key 5 can be made of steel plates, steel bars and the like. The shear key 5 is mounted on the corrugated profiled bottom plate 1 by means of bolt perforation, self-tapping screw or welding.

A decorative surface layer, preferably tiles or floor, is also provided on the structural net 2 and the cast-in-place layer 3.

Further, under special implementation requirements, a waterproof breathable film can be laid on the structural net 2 to further limit slurry leakage, but practice in practical construction operation proves that due to the fact that adaptive meshes are arranged on the structural net 2, only a very small amount of slurry leakage can be achieved after concrete pouring, and the waterproof breathable film is used to affect the bonding between the cast-in-place layer 3 and the structural net 2, but the implementation mode is to be exemplified in the embodiment.

Furthermore, the present invention has been described in detail with reference to the embodiments shown in the drawings, and those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details of the embodiments should not be construed as limitations of the invention, which is to be interpreted as broadly as the appended claims define the scope of the invention.
