Description

Technical Field

[0001] The utility model relates to the technical field of floor decking, in particular to a V-shaped double-folded edge steel bar truss floor decking. Background Art

[0002] Steel truss floor deck is a kind of building load-bearing component. Steel truss floor deck is made of steel truss and other materials. It has high strength and rigidity and can withstand large loads and deformation. It adopts standardized production, is light in weight, easy to install, and eliminates the traditional concrete surface plastering process, which can improve work efficiency and reduce construction costs.

[0003] In existing construction technology, the reinforcement of steel truss floor decking usually adopts a single structural fixing method, such as bolting or welding only. Although such traditional methods can meet the needs of structural stability to a certain extent, they have obvious shortcomings. On the one hand, due to the single fixing method, the firmness of the overall structure is limited, especially in terms of the bearing capacity of the ends, and the steel bars are easily deformed or damaged under heavy loads; on the other hand, traditional methods often require on-site processing and installation during the construction process, which is not only inefficient, but also increases the difficulty and safety hazards of on-site construction.

At the same time, the fixing block 24 also enhances the connection strength between the steel plate 21 and the bearing bottom formwork 1 through its distribution form. At the same time, the steel plate 21 is fixed to the bearing bottom formwork 1 through the screw holes 25 on the fixing block 24 by screws, thereby enhancing the overall stability and bearing capacity of the floor deck.

[0030] The steel plate 21 is fixed to the bearing bottom mold 1 by screws through screw holes 25 provided on the fixing block 24 .

[0031] The steel truss 3 includes a support transverse steel bar 31, the support transverse steel bar 31 is welded on the groove 22, the support vertical steel bar 32 is welded on the upper side of the support transverse steel bar 31, the top of the support vertical steel bar 32 is welded with an upper chord steel bar 33, two lower chord steel bars 34 are equidistantly welded on the top of the support transverse steel bar 31, the upper chord steel bar 33 is located between the two lower chord steel bars 34, and the outer side wall of the upper chord steel bar 33 is welded with a web steel bar 35.

[0033] The steel truss 3 is the main load-bearing structure of the floor decking. It is connected to the steel plate 21 through the support transverse steel bars 31 welded on the groove 22 of the reinforcement structure 2. The support vertical steel bars 32, the upper chord steel bars 33 and the lower chord steel bars 34 welded above the support transverse steel bars 31 together constitute the main frame of the truss.

The bottom bend of the web steel bars 35 is in close contact with the lower chord steel bars 34, ensuring the tightness and stability of the connection.

[0034] Embodiment 2

[0035] Based on the above embodiment 1, reference Figure 1 , Figure 2 The number of the arc-shaped grooves 23 is at least four and is evenly distributed in the width direction of the steel plate 21 .

[0036] There are at least four fixing blocks 24 , which are fixed on the outer side of the steel plate 21 in a rectangular array.

[0037] The number of the reinforcement structures 2 is 4 to 6 groups, which are evenly distributed on the upper side of the supporting bottom mold 1 .

[0038] Working principle: Please refer to Figure 1-Figure 5 As shown, when the floor is subjected to load, the load first acts on the steel truss 3, and the load is dispersed to the reinforcement structure 2 and the bearing bottom formwork 1 through the joint action of the upper chord steel bars 33, the lower chord steel bars 34 and the web steel bars 35. The reinforcement structure 2 is firmly connected to the bearing bottom formwork 1 through the steel plate 21 and the fixing block 24 to form an integral force system to ensure the stability and bearing capacity of the floor deck. At the same time, the arc groove 23 and the fixing block 24 further enhance the rigidity and stability of the floor deck.

[0039] Firstly, the bearing bottom formwork 1 serves as the foundation of the entire floor decking and provides the main supporting plane. It is responsible for bearing the weight of the upper reinforcement structure 2 and the steel truss 3, and transferring the load to the structure or foundation below through its surface. The reinforcement structure 2 is composed of a steel plate 21, a notch 22, an arc groove 23 and a fixing block 24. The steel plate 21 is fixed to the bearing bottom formwork 1 by screws through the screw holes 25 on the fixing block 24, thereby enhancing the overall stability and bearing capacity of the floor decking. The notch 22 is used for welding with the supporting transverse steel bars 31 of the steel truss 3 to form a solid connection, while the arc groove 23 is used for welding with the lower chord steel bars 34 of the steel truss 3 to make it more solid as a whole and enhance the bearing capacity of the end. At the same time, the fixing block 24 also enhances the connection strength between the steel plate 21 and the bearing bottom formwork 1 through its distribution form. The steel truss 3 is the main load-bearing structure of the floor decking. It is connected to the steel plate 21 through the support transverse steel bars 31 welded on the groove 22 of the reinforcement structure 2. The support vertical steel bars 32, the upper chord steel bars 33 and the lower chord steel bars 34 welded above the support transverse steel bars 31 together constitute the main frame of the truss. The web steel bars 35 are welded between the upper chord steel bars 33 and the lower chord steel bars 34 to enhance the overall stability and shear resistance of the truss. The bottom bend of the web steel bars 35 is in close contact with the lower chord steel bars 34 to ensure the tightness and stability of the connection.

[0040] Due to the overall synergistic effect of the utility model, when the floor deck is subjected to load, the steel truss 3 first bears and transfers the load, and the load is evenly distributed to the entire floor deck through the synergistic effect of the support transverse steel bars 31, the support vertical steel bars 32, the upper chord steel bars 33, the lower chord steel bars 34 and the web steel bars 35. The steel plate 21 of the reinforcement structure 2 is closely connected with the bearing bottom formwork 1, thereby further enhancing the overall stability and bearing capacity of the floor deck.
