Description

Technical Field

[0001] The utility model relates to the technical field of building steel structures, and particularly relates to a T-shaped support structure for a cantilever floor bearing plate. Background Art

[0002] With the development of the construction industry, the prefabricated construction method of steel structure buildings has become a major trend. Compared with traditional reinforced concrete structures, steel structure buildings have the advantages of high strength, fast construction speed, and good seismic performance. Most steel structure buildings use steel columns, steel beams, and steel bar truss floor bearing plates as the main construction content. Among them, most of the cantilever supports of the steel bar truss floor bearing plates use angle steel or other forms of temporary supports. One is angle steel support, and the other is to set up a scaffolding temporary support. By adding angle steel as the cantilever keel, a lot of materials are used and the cost is relatively high. And setting up a scaffolding for cantilever support takes a long time and requires a large investment in manpower and material resources. How to solve the structural support problem when the cantilever length is not large has become a key problem in related construction. Summary of the Invention

[0003] To overcome the deficiencies of the prior art, the utility model provides a T-shaped support structure for a cantilever floor bearing plate, which prefabricates the support structure on the steel beam, reduces the construction difficulty, improves the safety of operators, and expands the scope of application.

[0004] To achieve the above object, the T-shaped support structure for a cantilever floor bearing plate of the utility model includes an I-shaped steel beam.

A web is connected to the middle of the top flange and the bottom flange, and the web is perpendicular to the horizontal plane. A number of T-shaped support members are evenly distributed along the length direction of the I-shaped steel beam at equal intervals.

[0005] Further, the T-shaped support member includes a cantilever edge at the top. The cantilever edge is connected to the side surface of the top flange, and the cantilever edge is on the same horizontal plane as the top flange. The thickness of the cantilever edge is less than the thickness of the top flange, and the top surface of the cantilever edge is flush with the top surface of the top flange.

[0006] Further, the T-shaped support member further includes a diagonal bracing plate. The diagonal bracing plate is arranged below the cantilever edge and is perpendicular to the cantilever edge. One side of the diagonal bracing plate is connected to the web.

[0007] Further, the projection of the diagonal bracing plate on the cross-section of the I-shaped steel beam is a right trapezoid, and the end of the diagonal bracing plate far from the web is flush with the side surface of the cantilever edge.

[0008] Further, a side formwork is provided at the top of the I-shaped steel beam. The side formwork is supported by the top flange and the cantilever edge together, and a steel bar assembly is provided above the side formwork.

[0009] Further, welding studs are provided on the side formwork.

[0010] The cantilever floor slab T-shaped support structure of the present utility model forms a cantilever structure fixed on the structure of the building facade through the components fixed on the steel beam, solves the limitations of building the construction platform from the ground and adding cantilever steel beams, optimizes the construction environment of the operators, reduces the material input, and improves the applicable range of the cantilever steel structure.

The cantilever edge 21 and the top flange 11 are on the same horizontal plane. The thickness of the cantilever edge 21 is less than that of the top flange 11, and the top surface of the cantilever edge 21 is flush with the top surface of the top flange 11.

First, use an H-shaped steel automatic assembly machine to assemble the flange and the web 13 into a T shape first, and then use an H-shaped steel automatic assembly machine to assemble the T-shaped member with another flange into an H shape. The welding process is protected by carbon dioxide; for the main weld of the H-shaped steel in the fourth part, use a submerged arc automatic welding machine for welding, and use an H-shaped steel straightening machine for straightening after completion; according to the detailed design, draw the positions of the "T" - shaped members, assemble each member according to the line, and perform welding after the dimensions are correct, and then inspect according to the positioning reference line; the end is milled flat by a special lock - mouth machine and precisely drilled by a numerical control three - dimensional drill, and then sandblasted and rust - removed. During the steel structure processing stage, the staff can directly weld the members to the web 13 and the upper flange of the H - shaped beam. During the steel structure installation process, use a tower crane to directly install the steel beam to the corresponding edge position. This cantilever structure reduces the requirements for construction, saves labor and materials, and shortens the project duration.
