Description

Technical Field

[0001] The utility model belongs to the technical field of reinforced steel truss floor decks, in particular to a single-upper-chord, single-lower-chord, single-web reinforcement truss floor deck. Background Art

[0002] At present, the existing truss floor decking is mostly galvanized iron sheet and composite plate. In actual production and use, there is a common problem that the truss floor decking is difficult to demould. In addition, the bottom of the truss floor decking is uneven during use, resulting in unevenness, which reduces the strength of the truss floor decking and is prone to damage. The galvanized iron sheet truss floor decking trusses and the galvanized iron sheet are easily de-welded. During the cast-in-place process of the composite plate truss floor decking, a large area of ​​plate strips must be woven around the floor decking, which is difficult to construct and has high cost. The steel ramming frame has a foot, and if it is placed on the ground, it is in contact with the ground. In addition, the existing steel truss floor plates are mostly galvanized iron sheet truss floor plates and steel truss composite plates. The thickness of the galvanized iron sheet is 0.5 mm. The steel truss composite plate is a welded product of the steel truss. The steel truss is cast in situ with 60 mm thick concrete. In actual production applications, the disadvantage of the galvanized iron truss floor plate is that the iron sheet is too thin, only 0.5 mm, which is not easy to weld the steel truss firmly. During use, desoldering often occurs, and it cannot withstand the downward pressure during the concrete pouring process, causing the iron sheet to fall. The finished product has an uneven ground surface, which is inconvenient for construction in the later stage. It is only suitable for factory construction and cannot be used for residential buildings. The defect of the steel truss composite plate is that there are convex ribs on all four sides of the plate, which are called beard ribs in the industry. There is a 30 cm thick tape between the plates, and the bottom formwork is cast and connected. The bottom needs to be supported by a full-frame frame. The labor and material costs are high, and the construction period is long. For this reason, we propose a single upper chord, single lower chord, and single web truss floor deck. Utility Model Content

[0003] The purpose of the present invention is to provide a single upper chord, single lower chord, single web reinforcement truss floor decking to solve the existing truss floor decking proposed in the above background technology. In actual production and use, there is a common problem that the truss floor decking is difficult to demould, and the truss floor decking has an uneven bottom during use, which causes depression and easy desoldering, resulting in reduced strength of the truss floor decking and easy damage. The construction of the woven plate strip is difficult and costly. During use, desoldering occurs frequently, and it cannot withstand the downward pressure during the concrete pouring process, causing the iron sheet to fall. The finished product has an uneven floor surface, which is inconvenient for construction in the later stage, and is only suitable for factory building construction, not for residential buildings. There is a 30 cm thick tape between the plates, and the bottom formwork is poured and connected, and a full-frame support is required at the bottom, which has high labor and material costs and a long construction period.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a single upper chord, single lower chord and single web reinforcement truss floor deck, comprising a sound insulation board, a composite carbon fiber mesh and a truss, the truss comprising a skiving, a lower chord, web reinforcement, an upper chord, steel bars, a connecting column and a bottom support, the upper and lower surfaces of the sound insulation board are both provided with a composite carbon fiber mesh, the upper chord is located above the lower chord, the lower chord and the upper chord are connected to the web reinforcement, the front and rear of the lower chord are both provided with skiving, and the skiving is connected to the web reinforcement, the connecting column passes through the sound insulation board and the composite carbon fiber mesh, the steel bar is located at one end of the connecting column, and the bottom support is located at the other end of the connecting column.

[0005] Preferably, two composite carbon fiber meshes are provided.

[0006] Preferably, the truss is fixedly connected to the composite carbon fiber mesh.

[0007] Preferably, composite foam is provided inside the sound insulation board.

[0008] Preferably, the upper surface of the lower chord is provided with a transverse rib, and the transverse rib connects the plurality of lower chords.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] When the above-mentioned structure of the present application is adopted and after pouring concrete, the steel chord truss can effectively improve the strength of the entire floor slab and realize the installation without disassembly. While effectively ensuring its use effect, it also greatly reduces its operation difficulty. The transverse reinforcement connects multiple trusses to enhance their strength. The connecting column connects the sound insulation board to the floor decking, and should avoid trusses and transverse reinforcements, 4-6 pieces / square meter, so as to ensure the connection strength between the sound insulation board and the floor slab.
