Description

Technical Field

[0001] This invention relates to a floor slab, specifically a truss-type floor slab. Background Technology

[0002] When constructing buildings with reinforced concrete frames, steel bars and formwork are typically erected on the construction site, and then concrete is poured in to form pillars. During construction, steel bars must be pre-fixed at the base of each pillar, and construction workers must tie the steel bars one by one. After the formwork is erected and fixed, grouting is carried out. The next step can only be carried out after the concrete inside the formwork has solidified. This process is somewhat slow and can easily prolong the construction time.

[0003] Subsequently, the evolution from traditional reinforced concrete buildings to the currently widely used steel frame structures has led to significant changes in the floor slabs. For the treatment of floor slabs in general steel frame structures, please refer to... Figure 1 The existing floor slab 1 has multiple equidistant beams 11, a steel bearing plate 12 mounted on the beams 11, and concrete 2 filled on the steel bearing plates 12. During construction, the steel bearing plates 12 are pre-laid on the beams 11, and then concrete 2 is poured on top of the steel bearing plates 12 to form the floor. However, since the bottom surface of the steel bearing plate 12 is still a grooved steel plate surface, this grooved ceiling is also very uncoordinated to the lower floor. In order to achieve a flat and beautiful appearance, it is necessary to carry out a complete beautification construction of the ceiling, or to suspend it under the beams 11 with a light steel frame to cover the beams 11. Moreover, if a flat appearance is required, additional decoration costs are needed, such as subsequent work such as steel frame or plastering. It is necessary to improve this. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a truss-type floor slab that can be planned according to the site dimensions and support strength, and after grouting, a flat surface can be quickly obtained with simple treatment, thus achieving the convenience of quick installation and on-site construction.

[0005] Therefore, the present invention provides a truss-type floor slab, comprising a plurality of spaced-apart support groups and a mesh mold on which the plurality of support groups are mounted; wherein the mesh mold has a top surface welded and fixed to the plurality of support groups, a bottom surface opposite to the top surface, and a plurality of openings penetrating the top surface and the bottom surface; furthermore, each support group has a plurality of spaced-apart main supports and a connecting frame surrounding the periphery of the main supports, wherein the connecting frame has a plurality of spaced-apart surrounding units and a plurality of connecting units integrally connected to the plurality of surrounding units, the plurality of surrounding units and the plurality of connecting units being welded to the plurality of main supports, each surrounding unit being integrally bent to surround the periphery of the plurality of main supports, each surrounding unit having at least two surrounding segments after bending, and each surrounding segment extending between any two adjacent main supports in a straight-line extension manner, each connecting unit extending more obliquely between any two adjacent surrounding units, thereby the connecting frame being continuously bent to surround the periphery of the plurality of main supports and welded and fixed to the plurality of main supports.

[0006] As a further improvement of the present invention, the multiple main supports are arranged in a non-linear manner to be spaced apart from each other, so that when the connecting frame surrounds the multiple main supports, it forms an accommodating space with a polygonal profile.

[0007] As a further improvement of the present invention, the top surface of the mesh is welded to the plurality of the surrounding units.

[0008] As a further improvement of the present invention, the top surface of the mesh is welded to the plurality of the connecting units.

[0009] As a further improvement of the present invention, a plurality of auxiliary rods are added, which are inserted through a plurality of support groups and connected to the plurality of support groups.

[0010] As a further improvement of the invention, a concrete is poured onto the top surface of the mesh mold to completely cover the multiple support groups.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] This invention not only effectively increases the strength of the support assembly, but also allows the truss-type floor slab to be prefabricated in the factory and then directly transported to the work site for laying. It is then assembled and connected with the mesh mold. Since the mesh mold is located at the bottom after connection, the floor slab is flat after laying. The top surface of the mesh mold and multiple support assemblies can be filled with concrete for grouting. After grouting, the concrete can be flat on the top or bottom surface of the mesh mold, so no additional leveling treatment is required. After grouting, some concrete can be passed through the opening to the bottom surface of the mesh mold, which can be directly used for subsequent plastering, thus quickly obtaining a flat surface and achieving the convenience of rapid installation and on-site construction.

[0042] The above and other technical contents, features and effects of the present invention will become clear from the following detailed description of the preferred embodiments with reference to the accompanying drawings.

[0043] See Figures 2 to 5 In a first preferred embodiment of the truss-type floor slab 3 of the present invention, the truss-type floor slab 3 includes a plurality of spaced-apart support groups 31 and a mesh mold 32 on which the plurality of support groups 31 are mounted; wherein the plurality of support groups 31 are welded to the mesh mold 32, and the mesh mold 32 has a top surface 321 welded and fixed to the plurality of support groups 31, a bottom surface 322 opposite to the top surface 321, and a plurality of openings 323 penetrating the top surface 321 and the bottom surface 322; furthermore, each support group 31 has a plurality of spaced-apart main supports 311 and a connecting frame 312 surrounding the periphery of the main supports 311, and the connecting frame 312 has a plurality of spaced-apart surrounding units 3121 and a plurality of connecting units 3121 integrally connected to the plurality of surrounding units 3121. 122. Multiple surrounding units 3121 and multiple connecting units 3122 are welded to multiple main supports 311. Each surrounding unit 3121 is integrally bent to surround the periphery of multiple main supports 311. After bending, each surrounding unit 3121 has at least two surrounding segments 31211. Each surrounding segment 31211 extends between any two adjacent main supports 311 and extends in a straight line. That is, as shown in the figure, each surrounding segment 31211 is straight and not curved or arc-shaped. At the same time, because the surrounding segment 31211 is designed in a straight line, it can improve the overall strength when connected with the main supports 311. In this embodiment, the support group 31 and another support group 31 are spaced apart, and the distance between them can be adjusted according to the required strength.

[0044] Continuing from the above, each connecting unit 3122 extends more obliquely between any two adjacent surrounding units 3121, thereby the connecting frame is continuously bent to surround the periphery of the plurality of main supports 311 and is welded and fixed to the plurality of main supports 311. That is, each connecting unit 3122 can be obliquely positioned relative to the plurality of main supports 311, so that any connecting unit 3122 extends obliquely from one surrounding segment 31211 of any surrounding unit 3121 to another surrounding segment 31211 of another adjacent surrounding unit 3121. Furthermore, in this embodiment, the multiple main supports 311 are arranged in a non-linear manner to be spaced apart from each other, so that when the connecting frame 312 surrounds the multiple main supports 311, it forms a accommodating space 313 with a polygonal profile. That is, when the connecting frame 312 surrounds the multiple main supports 311, it can form three or more turning areas 3123. Therefore, the accommodating space 313 defined by the connecting frame 312 surrounding the multiple main supports 311 can form a polygonal profile with at least three sides (i.e., three or more sides), as shown in the figure. Figure 2 The triangular shape shown, or like Figure 6 The four-cornered shape shown is not specified in this embodiment. Figure 2 The triangular shape is used as an example for illustration; furthermore, in this embodiment, a concrete 4 is poured on the top surface 321 of the mesh mold 32 to completely cover the multiple support groups 31; finally, the top surface 321 of the mesh mold 32 is welded to the multiple surrounding units 3121, or the top surface 321 of the mesh mold 32 is welded to the multiple connecting units 3122. In this embodiment, the welding of the top surface 321 of the mesh mold 32 to the multiple surrounding units 3121 is used as an example.

[0045] See Figures 2 to 5 In use, the support assembly 31 can be prefabricated in a factory using a molding device. This involves arranging multiple main supports 311, then bending the connecting frame 312 using the molding device. The connecting frame 312 wraps around the main supports 311, ensuring a tight connection between the connecting frame 312 and each main support 311. This connection can be achieved through welding. After the connecting frame 312 is encircled and fixed to the main supports 311, the support assembly 31 is complete. The support assemblies 31 are then transported to the construction site for installation. A mesh mold 32 is placed at the bottom of each support assembly 31, and the mesh mold 32 is welded to the surrounding unit 3121 or connecting unit 3122 of each support assembly 31. This completes the installation. Figure 3As shown, the floor slab of the building is constructed by pouring concrete 4 over the multiple support groups 31 and the mesh mold 32 until the concrete 4 fills the support groups 31, creating a flat surface above them. During the pouring of the concrete 4, the mesh mold 32 has openings 323. These openings not only provide drainage for the concrete 4 but also allow some of the concrete 4 to flow through the openings 323 from the top surface 321 of the mesh mold 32 to below the bottom surface 322. Subsequently, the concrete 4 that has flowed over the bottom surface 322 only needs to be ground smooth to reveal the area below the bottom surface 322 of the mesh mold 32. The surface is flat, and the concrete 4 surface below the mesh mold 32 is also flat, which facilitates subsequent plastering work and can quickly form a flat ceiling. The concrete 4 on the top surface 321 of the mesh mold 32 can also be smoothed to quickly form a floor. Therefore, by wrapping the connecting frame 312 around the multiple main supports 311, the overall strength can be increased. At the same time, the support group 31 can be prefabricated in the factory and then directly transported to the work site for laying before being assembled and connected with the mesh mold 32. After connection, since the mesh mold 32 is located at the bottom, it is flat and beautiful after laying, without the need for additional decoration, so as to achieve rapid assembly and improve the speed of on-site construction.

[0046] See Figure 7 In the second preferred embodiment of the present invention, the truss-type floor slab 3 includes a plurality of spaced support groups 31 and a mesh mold 32 on which the plurality of support groups 31 are mounted. The above structure and the desired effect are the same as those in the first embodiment, and will not be described in detail. In particular, in this embodiment, a plurality of auxiliary rods 33 are added. The plurality of auxiliary rods 33 pass through the plurality of support groups 31 and are connected to the plurality of support groups 31. With the plurality of auxiliary rods 33, the support group 31 can be connected to another support group 31 not only through the mesh mold 32, but also through the plurality of auxiliary rods 33, which can more effectively improve the overall strength.

[0047] In summary, the truss-type floor slab of the present invention, by including multiple spaced-apart support groups and a mesh mold for mounting the multiple support groups, wherein multiple openings are formed in the mesh mold, and each support group includes multiple spaced-apart main supports and at least one connecting frame that connects the multiple main supports, will help improve the overall strength of the support group. At the same time, the support group can be prefabricated in the factory and directly transported to the work site for laying, and then assembled and connected with the mesh mold. Since the mesh mold is located at the bottom after connection, it is flat after laying, so no additional leveling treatment is required, achieving the effect of rapid construction and cost saving. Therefore, it can indeed achieve the purpose of the present invention.

[0048] The above description is merely illustrative of preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the patent of the present invention.
