Description

Technical Field

[0001] The utility model belongs to the technical field of floor decking, and in particular relates to a semi-automatic sheet metal welding steel bar floor decking. Background Art

[0002] Semi-automatic sheet metal welding steel bar floor deck, also known as steel bar truss floor deck, is an important component in building steel structure engineering. It changes and reduces the convex high pressure type of the original floor deck, uses semi-automatic sheet metal welding equipment in the factory, processes the steel bars in the floor slab into steel bar trusses, and welds them with galvanized sheets to form a composite floor deck. The steel bar truss floor deck includes a floor deck body and a steel bar truss. The floor deck body includes grooves, which are arranged at intervals on the floor deck body. When the steel bar truss floor deck is constructed, it is necessary to first fix the floor deck body, then weld the steel bar truss to the floor deck body, and then pour concrete on the floor deck body.

[0003] Most of the existing semi-automatic sheet metal welded steel bar floor decking use galvanized steel plates as the base, and weld the steel bar trusses on the galvanized steel plates. During normal transportation, curling may occur due to the uneven surface of the galvanized steel plates. When laying in the summer, the surface temperature of the semi-automatic sheet metal welded steel bar floor decking is relatively high due to the sunlight. Working under high temperature for a long time may easily cause accidents to the workers. Summary of the invention

[0004] The utility model provides a semi-automatic sheet metal welding steel bar floor deck, which aims to solve the problem that most of the existing semi-automatic sheet metal welding steel bar floor decks use galvanized steel plates as bases and weld steel bar trusses on the galvanized steel plates. During normal transportation, curling may occur due to the uneven surface of the galvanized steel plates. When laid in summer, the surface temperature of the semi-automatic sheet metal welding steel bar floor deck is relatively high due to the exposure to sunlight, and workers may easily encounter accidents when working at high temperatures for a long time.

[0005] An embodiment of the utility model provides a semi-automatic sheet metal welded steel bar floor deck, comprising a bottom mold pouring cavity, in which a wire mesh is arranged, on which a steel bar truss assembly is arranged, and a mesh cloth is sandwiched between the steel bar truss assembly and the wire mesh.

[0006] Furthermore, the bottom mold casting cavity includes a bottom plate, a protrusion is fixedly connected to one side of the upper surface of the bottom plate, the protrusion is integrally formed with the bottom plate, a baffle is installed on the peripheral side of the bottom plate, and an edge is fixedly connected to the top of the baffle on the side opposite to the protrusion, the edge is arranged toward the protrusion, and the edge is integrally formed with the baffle.

[0007] By adopting the above technical solution, the concrete poured into the bottom plate can be formed into a fixed shape through the bottom plate and the enclosure. When the concrete solidifies, due to the setting of the protrusions and the edges, the two sides of the concrete can form shapes that fit each other, so that the two concrete slabs can fit tightly. At the same time, the floor decking made of concrete will no longer curl during transportation and will not generate high temperatures when exposed to sunlight, thereby avoiding accidents to workers.

[0008] Furthermore, the steel bar truss assembly includes two web bars, which are evenly spaced and installed on the wire mesh, an upper chord steel bar is installed at the top between the two web bars, and lower chord steel bars are installed on both sides of the two web bars.

[0009] By adopting the above technical solution, the entire floor deck can have a greater bearing capacity through the arrangement of the web reinforcement, the upper chord reinforcement and the lower chord reinforcement.

[0010] Furthermore, the web member reinforcement includes an upper rod portion and a lower rod portion, the two web member reinforcements are in the shape of an isosceles triangle, the lower rod portion is bent toward a side away from the upper chord reinforcement, and is fixedly connected to the wire mesh.

[0011] By adopting the above technical solution, an isosceles triangle is formed between the two web reinforcements and the bottom plate, and is welded to the wire mesh, so that the overall floor decking can have a larger bearing capacity.

[0012] Furthermore, connecting steel bars are fixedly connected between the upper rod parts.

[0013] By adopting the above technical solution, the overall bearing capacity is further enhanced.

[0014] The beneficial effects of the utility model are:

[0015] 1. The utility model can form a fixed shape of concrete poured into the bottom plate through the arrangement of the bottom mold pouring cavity, the bottom plate and the enclosure. When the concrete solidifies, due to the arrangement of the protrusions and the edges, the two sides of the concrete plate can form shapes that fit each other, so that the two concrete plates can fit closely together. At the same time, the floor decking plate composed of concrete will not curl during transportation, and will not generate high temperature under sunlight, thereby avoiding accidents caused by workers working under high temperature for a long time.

[0016] 2. The utility model provides the protrusions and the edges so that the two sides of the solidified concrete can form shapes that fit each other, which facilitates the close fit of the two pieces of concrete and prevents the concrete from leaking from the junction of the two floor decks when pouring the concrete.

[0017] 3. The utility model provides the wire mesh and the mesh cloth, and the mesh cloth has high tensile strength and deformation resistance, can withstand external forces for a long time, improves the overall crack resistance and durability, and the wire mesh can also strengthen the load-bearing capacity.

[0018] 4. The utility model can further enhance the overall load-bearing capacity by setting connecting steel bars.

At the same time, the floor deck composed of concrete will not curl during transportation, and will not generate high temperature when exposed to sunlight, thereby avoiding accidents to workers.

[0027] Reference Figure 1-3 A wire mesh 2 is arranged in the bottom mold casting cavity 1, and a steel truss assembly 4 is arranged on the wire mesh 2. The steel truss assembly 4 includes two web steel bars 41, and the two web steel bars 41 are evenly spaced and installed on the wire mesh 2. The web steel bars 41 include an upper rod portion 411 and a lower rod portion 412. The two web steel bars 41 are in the shape of an isosceles triangle, and the lower rod portion 412 is bent toward a side away from the upper chord steel bars 42, and is fixedly connected to the wire mesh 2, so that the overall floor deck can have a larger bearing capacity, and connecting steel bars 44 are also fixedly connected between the upper rod portions 411, which further enhances the overall bearing capacity, and an upper chord steel bar 42 is installed on the top between the two web steel bars 41, and lower chord steel bars 43 are installed on both sides of the two web steel bars 41.
