AI Technical Summary
Due to the single structure of existing ordinary steel bar trusses, they have large amounts of consumables and high costs, which is not conducive to use.
The prefabricated composite carbon fiber enhances the bottom of the reinforced reinforced truss tower bearing board, including the upper string, lower string, single abdominal rod, steel bars, cold pulled wires, horizontal tendons, and composite carbon fibers. Through the combination and connection of these components Sexual and intensity.
By increasing the cold pull -ups of contact area and intensity, and connecting multiple upper and lower stringed steel bars, it effectively improves the connection strength and stability of the reinforcement truss and reduces the production cost.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel bar trusses, and in particular relates to an assembled composite carbon fiber reinforced non-dismantling bottom formwork plane steel bar truss floor deck. Background Art
[0002] At present, the existing ordinary steel trusses are composed of a single upper chord, two lower chords, and a web bar on each side. However, this will result in a large amount of consumables and high cost in making the steel trusses, which is not conducive to use. For this reason, we propose an assembled composite carbon fiber reinforced flat steel truss floor deck that does not require disassembly of the bottom formwork. Utility Model Content
[0003] The purpose of the utility model is to provide an assembled composite carbon fiber reinforced non-disassembly bottom formwork flat steel truss floor decking plate to solve the problem that the existing common steel trusses proposed in the above background technology are composed of a single upper chord, two lower chords, and a web bar on each side, but this will result in a large amount of consumables for making steel trusses, high costs, and is not conducive to use.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled composite carbon fiber reinforced bottom formwork-free flat steel bar truss floor decking plate, comprising an upper chord, a lower chord, a single web bar, steel bars, cold-drawn wires, transverse bars and composite carbon fibers, the upper chord being located above the lower chord, the single web bar connecting the upper chord and the lower chord, the upper chord, the lower chord, the single web bar and steel bars being located above the cold-drawn wires, the transverse bars being located below the lower chord, and the composite carbon fibers being located below the cold-drawn wires.
[0005] Preferably, the steel bars connect multiple upper chords.
[0006] Preferably, the number of the upper strings is the same as the number of the lower strings, and the cold-drawn wire is fixedly connected to the lower strings.
[0007] Compared with the prior art, the beneficial effects of the utility model are:
[0008] Cold drawn wire can increase the contact area between the entire device and the concrete, effectively improving its connection strength, while steel bars can connect multiple upper and lower chords to prevent the upper and lower chords from shifting during concrete pouring. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a schematic diagram of the overall structure of the utility model.
[0010] In the figure: 1. Upper chord; 2. Lower chord; 3. Single web bar; 4. Steel bar; 5. Cold drawn wire; 6. Transverse rib; 7. Composite carbon fiber. DETAILED DESCRIPTION
[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0012] See also Figure 1 The utility model provides an assembled composite carbon fiber reinforced bottom formwork-free flat steel truss floor deck, including an upper chord 1, a lower chord 2, a single web bar 3, a steel bar 4, a cold-drawn wire 5, a transverse bar 6 and a composite carbon fiber 7. The upper chord 1 is located above the lower chord 2, the single web bar 3 connects the upper chord 1 and the lower chord 2, the upper chord 1, the lower chord 2, the single web bar 3 and the steel bar 4 are all located above the cold-drawn wire 5, the transverse bar 6 is located below the lower chord 2, and the composite carbon fiber 7 is located below the cold-drawn wire 5.
[0013] Specifically, the steel bar 4 connects a plurality of upper chords 1 , the number of the upper chords 1 is the same as the number of the lower chords 2 , and the cold drawn wire 5 is fixedly connected to the lower chords 2 .
