AI Technical Summary
In complex over-limited building structures, the existing finished steel bar truss floor slabs are insufficient, resulting in a large amount of materials and increased construction workload. Conventional alternatives such as steel plates are covered with bolts and nails, laying cast-in-place boards has large amounts of materials and large construction volume. The problem.
Triangular steel bar brackets, plate top steel bars and plate bottom steel bars are used to combine steel plates and steel beams to form an overall structure, reduce the amount of bolts and nails, improve construction stiffness, and vertically connect the bottom plate to enhance the strength of the bracket, reduce the material and construction workload.

Description
Technical Field
[0001] The utility model relates to the field of floor decking, in particular to a steel bar truss floor decking. Background Art
[0002] In recent years, with the rapid development of the national economy and the development of technology, the requirements for building facade modeling and plane space utilization have been continuously increasing, and various complex and over-limit structures such as large-span floors, large cantilevered floors, and overweight floor slabs are increasing.
[0003] As more complex projects are being built, the role and requirements of floor slabs on the overall structure are becoming greater and greater. In this case, the stress of the finished steel truss floor slabs produced by the manufacturer often fails to meet the requirements. The current conventional practice is to replace the steel truss floor slabs with steel plates covered with studs and cast-in-place slabs. This method results in large material consumption and large on-site construction workload. Therefore, it is urgent to develop a floor slab structure that can reduce material consumption and construction workload. Utility Model Content
[0004] The purpose of the utility model is to provide a steel bar truss floor decking plate, which has the characteristics of reducing the amount of materials used and the amount of construction work.
[0005] The technical solution of the utility model is as follows: a steel truss floor deck comprises a floor deck main body, a frame is arranged inside the floor deck main body, the frame comprises a steel plate, a group of disconnected triangular steel bar brackets are arranged on the steel plate, the upper part of the triangular steel bar brackets is provided with slab top steel bars, and the lower part of the triangular steel bar brackets is provided with slab bottom steel bars.
[0006] In the aforementioned steel bar truss floor deck, the top steel bars and the bottom steel bars of the slab both include longitudinal steel bars and transverse steel bars.
[0007] In the aforementioned steel bar truss floor deck, the triangular steel bar support includes a triangular support body, a connecting bottom plate is provided on one side of the bottom end of the triangular support body, and the connecting bottom plate and the triangular support body are vertically distributed.
[0008] In the aforementioned steel bar truss floor deck, a steel beam is provided below the steel plate, and bolts are provided on the top of the steel beam.
[0009] Compared with the prior art, the utility model adopts a triangular steel bar support, the bottom and top steel bars of the slab arranged at the upper and lower ends of the triangular steel bar support, and a steel plate to form a whole, which can bear the concrete load and construction live load during construction; this method not only ensures the joint force of the steel plate and the steel bar, saves the amount of bolts, but also improves the rigidity of the floor slab during construction, so that the on-site operation does not need to support the formwork and reduces the on-site workload. Compared with conventional practices, it has obvious advantages in economy and convenience. At the same time, the bottom of the triangular steel bar support of the utility model is provided with a connecting bottom plate perpendicular to it, so as to provide the connection strength of the support and further save steel. That is, under the premise of ensuring the structural strength, the present application can effectively reduce the structural materials and reduce the construction operation workload, thereby better meeting the construction needs.

[0016] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0017] Embodiment. A steel truss floor deck is constructed as follows Figure 1-5 As shown, it includes a floor decking body, a frame is arranged inside the floor decking body, and the frame includes a steel plate 1. A group of disconnected triangular steel bar supports 2 are arranged on the steel plate 1. The upper part of the triangular steel bar supports 2 is provided with a plate top steel bar 3, and the lower part of the triangular steel bar supports 2 is provided with a plate bottom steel bar 4.
[0018] The slab top reinforcement 3 and the slab bottom reinforcement 4 both include longitudinal reinforcement and transverse reinforcement.
[0019] The triangular steel bar support 2 includes a triangular support body 201 , a connecting bottom plate 202 is provided on one side of the bottom end of the triangular support body 201 , and the connecting bottom plate 202 and the triangular support body 201 are vertically distributed.
[0020] A steel beam 5 is provided below the steel plate 1 , and a bolt 6 is provided on the top of the steel beam 5 .
[0021] The contact position is fully welded.
[0022] In the structural floors where the floor slabs need to be strengthened, the floor decking is designed through the following steps: 1) The locations where the conventional reinforced steel truss floor slabs have insufficient stress are obtained based on the floor slab stress; 2) The new truss floor slab area is represented on the plane, and the requirements for the fire retardant coating on the bottom of the steel plate are explained; 3) The required steel plate thickness and steel bars for the new truss floor slab are obtained based on the calculated stress of the floor slab; 4) Detailed drawings are drawn to indicate the floor slab and steel plate information, fully weld the steel plate and the triangular steel bar bracket at the contact location, and set bolts at the top of the steel beam; 5) Additional steel bars can be used at locations where the stress of some floor slabs is relatively large.
[0023] For finished truss floor slabs that cannot meet the stress requirements within the floor plane, the steel truss floor slab of the present application is used to strengthen the bearing capacity of the floor slab, increase the stiffness of the floor slab and reduce the use of bolts on the slab, thereby improving the safety and economy of the structure and the convenience of construction.
