Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar truss floor decking, and in particular relates to a single upper chord, single lower chord, single web bar, composite carbon fiber reinforced double-frame plane truss floor decking. 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, and 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 easy to be unwelded. 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 costly. 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 welding product of the steel truss, that is, the steel truss and It is made of 60 mm thick cast-in-place concrete. In actual production applications, the disadvantage of galvanized iron sheet truss floor slabs is that the iron sheet is too thin, only 0.5 mm, which is not easy to weld firmly to the steel truss. 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 slab is that there are convex ribs on all four sides of the slab, which are called beard ribs in the industry. There is a 30 cm thick tape between the slabs, and the bottom formwork is cast and connected. The bottom needs to be supported by a full-frame frame. The labor material cost is high, and the construction period is long. For this reason, we propose a single upper chord, single lower chord, single web bar, composite carbon fiber reinforced double-frame flat truss floor decking. Utility Model Content

[0003] The purpose of the utility model is to provide a single upper chord, single lower chord, single web composite carbon fiber reinforced double-frame plane truss floor decking plate to solve the existing truss floor decking plate proposed in the above background technology. In actual production and use, there is a common problem that the truss floor decking plate is difficult to demould, and the truss floor decking plate has an uneven bottom during use, causing depression and easy desoldering, resulting in reduced strength of the truss floor decking plate and easy damage. The construction of the woven plate belt is difficult and costly. During use, desoldering often occurs, and it cannot withstand the downward pressure during the concrete construction and pouring process, causing the iron sheet to fall. The ground of the finished product is uneven, which is not convenient for construction in the later stage, and it is only suitable for factory building construction, not for residential buildings. There is a 30-centimeter thick tape between the plates, and the bottom mold is cast and connected. The bottom needs to be supported by a full-frame support, which has high labor and material costs and a long construction period.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a single upper chord, single lower chord, single web composite carbon fiber reinforced double-frame plane truss floor decking plate, comprising a bottom mold, a composite carbon fiber mesh, cold-drawn wires, transverse reinforcements, longitudinal reinforcements, a lower chord, a foot and an upper chord, the composite carbon fiber mesh being located above the bottom mold, the cold-drawn wires being located at both ends of the transverse reinforcements and welded to both ends of the transverse reinforcements, the transverse reinforcements being located above the composite carbon fiber mesh, and both ends of the transverse reinforcements being fixedly connected to the cold-drawn wires, the lower chord being located above the transverse reinforcements, an upper chord being arranged above the lower chord, the upper chord being connected to the lower chord by the foot, and the longitudinal reinforcements being connected to the foot.

[0005] Preferably, the length of the bottom mold is 1.2 meters, and there are two lower chords, two skimmers, and two upper chords, which are respectively located on both sides of the upper surface of the bottom mold.

[0006] Preferably, two cold-drawn wires are provided and are respectively located on both sides of the upper surface of the composite carbon fiber mesh.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The lower chord, the skive, the upper chord and the bottom formwork can be effectively connected with the composite carbon fiber mesh through transverse and longitudinal reinforcements. After pouring concrete, the stability and firmness of the entire floor deck can be effectively guaranteed, while reducing labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
