Description

Technical Field

[0001] The utility model belongs to the technical field of assembled reinforced concrete floor slabs, and in particular relates to a thin plane reinforced concrete truss floor slab. Background Art

[0002] With the development of the times, urbanization construction has gradually advanced, and more and more buildings have emerged. In the continuous rise of buildings, the most important link is concrete material.

[0003] Existing concrete materials are greatly affected by temperature and humidity. In actual use, concrete materials are easily affected by temperature, causing expansion or contraction, resulting in the peeling of the facade surface, affecting the aesthetics of the building, and have certain limitations. Utility Model Content

[0004] The purpose of the present utility model is to provide a thin flat steel truss floor deck to solve the problem raised in the above background technology that the existing concrete materials are greatly affected by temperature and humidity. In actual use, the concrete materials are easily affected by temperature, thereby expanding or contracting, causing the facade surface to fall off, affecting the aesthetics of the building, and having certain limitations.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thin flat steel bar truss floor deck, comprising a non-disassembly bottom formwork, one side of the non-disassembly bottom formwork is fixedly connected with vertical fixed steel bars, there are several vertical fixed steel bars, the surface of the vertical fixed steel bars is fixedly connected with horizontal fixed steel bars, the surface of the horizontal fixed steel bars is fixedly connected with prestressed steel bar trusses, and the prestressed steel bar trusses are provided with expansion joints.

[0006] Preferably, one end of the vertical fixed steel bar is fixedly connected to the non-disassembly bottom mold through a first fixed plate.

[0007] Preferably, the prestressed steel bar truss is fixedly connected to the horizontal fixed steel bars through a second fixed plate.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] 1. The utility model can well cope with climate temperature changes, allowing the internal structure of the concrete to expand or contract, avoiding deformation of the overall structure, strengthening the overall structure, extending the service life of the concrete, and making the building structure more stable.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-3 The utility model provides a technical solution: a thin flat steel truss floor deck, including a non-dismantling bottom formwork 5, one side of the non-dismantling bottom formwork 5 is fixedly connected with a vertical fixed steel bar 1, the number of vertical fixed steel bars 1 is several, the surface of the vertical fixed steel bar 1 is fixedly connected with a horizontal fixed steel bar 2, the surface of the horizontal fixed steel bar 2 is fixedly connected with a prestressed steel truss 3, and the prestressed steel truss 3 is provided with an expansion joint 4.

[0016] In this embodiment, by adopting different numbers of expansion joints 4 according to different usage environments and adopting the jump-bin casting method for the expansion joints 4, the expansion joints 4 are prestressed, which can temporarily cope with the expansion and contraction of the concrete material. Combined with the stability of the overall steel structure, it can avoid deformation of the facade and affect the overall structure. This design method can well cope with climate temperature changes, allowing the internal structure of the concrete to expand or contract, avoiding deformation of the overall structure, strengthening the overall structure, extending the service life of the concrete, and making the building structure more stable.

[0017] Specifically, one end of the vertical fixed steel bar 1 is threadedly fixedly connected to the non-disassembly bottom form 5 through a first fixed plate 6.

[0018] In this embodiment, the vertical fixing steel bars 1 are provided to enhance the overall vertical stability.

[0019] Specifically, the prestressed steel bar truss 3 is fixedly connected to the horizontal fixed steel bar 2 via the provided second fixing plate 7 .

[0020] In this embodiment, expansion joints are reserved in the prestressed steel bar trusses 3 to cope with the expansion and contraction of concrete and avoid structural changes.

[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
