Description

Truss type floor slab

The present invention relates to a floor panel, in particular to a truss type floor panel.

Generally, when constructing buildings with reinforced concrete skeletons, steel bars and formwork are usually erected at the construction site, and then concrete is poured to form pillars. During construction, the steel bars need to be pre-fixed at the base of each pillar. After the construction workers bundle the steel bars one by one and erect the fixed formwork, they then proceed with the grouting work. They must wait until the concrete in the formwork has solidified before proceeding to the next project. The construction time is a bit slow and may easily extend the construction time. .

Later, the traditional concrete reinforced buildings evolved to the steel frame structures that are commonly used today. The floor slabs laid on the floors also underwent major changes. Generally, steel frame structures are used in the processing of floor slabs. Refer to Figure 1. The conventional floors The plate 1 has a plurality of equidistant beams 11, a steel supporting plate 12 arranged on the beams 11, and a concrete 2 filled on the steel supporting plates 12; during construction, it is mainly pre-laid with The steel supporting plate 12 is placed on the cross beam 11, and concrete 2 is poured above the steel supporting plate 12 to form the floor; however, it is found that since the bottom surface of the steel supporting plate 12 is still a concave and convex groove-shaped steel plate surface, this concave and convex for the lower floor The trough-shaped ceiling is also extremely uncoordinated. In order to achieve the purpose of smoothness and beauty, the ceiling must be fully beautified, or it must be suspended under the beam 11 with a light steel frame, and at the same time it can cover the beam 11, and if the appearance requires To level it, additional decoration costs are required, such as steel frame or clay powder finishing and other subsequent operations, which really need to be improved.

Therefore, the purpose of the present invention is to provide a truss floor slab that can be planned according to the on-site length and support strength, and can quickly obtain a flat surface with simple treatment after grouting, thereby achieving the convenience of installation and on-site construction.

Therefore, the present invention provides a truss floor plate, which includes a plurality of spaced support groups and a mesh mold on which the support groups are mounted; wherein the mesh mold has a top surface welded and fixed to the support groups, a bottom surface opposite to the top surface, and a plurality of openings penetrating the top surface and the bottom surface; in addition, each support group has a plurality of spaced main brackets and a connecting frame surrounding the outer periphery of the main bracket, and The aforementioned connecting frame has a plurality of spaced-apart surrounding units and a plurality of connecting units integrally connected to the surrounding units. The surrounding units and the connecting units are connected to the main supports by welding. Each surrounding unit is integrally bent to surround the outer periphery of the main supports. Each surrounding unit has at least two surrounding sections after being bent, and each surrounding section extends between any two adjacent main supports and extends in a straight line. Each connecting unit extends obliquely between any two adjacent surrounding units, so that the connecting frame is continuously bent to surround the outer periphery of the main supports and is welded and fixed to the main supports, which can effectively increase the strength of the support group. The truss floor can be pre-fabricated in the factory and then directly moved to the work site for laying, and then assembled and connected with the mesh form. At the same time, after the connection, since the mesh form is set at the bottom, After being laid, it is flat, and the top surface of the mesh form and the supporting groups can be filled with concrete. After the concrete is filled, the top surface or the bottom surface of the mesh form can be flat, so no additional flattening treatment is required. At the same time, after the grouting, part of the concrete is passed through the opening to the bottom surface of the mesh form, which can be directly used for subsequent painting, so that a flat surface can be quickly obtained, achieving the convenience of rapid installation and on-site construction.
