[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-2 This utility model provides an embodiment of a steel truss floor deck, including a base plate 1. The base plate 1 serves as the basic support structure for the entire steel truss floor deck, bearing the upper assembly components 2 and support components 3, as well as related construction loads and the weight of concrete. It provides a foundation platform for the installation and fixing of other components. The outer wall of the base plate 1 is provided with assembly components 2, which are used to realize the rapid splicing between multiple base plates 1, enabling the floor deck to be quickly assembled and expanded according to construction needs, improving construction efficiency, and ensuring the stability and reliability of the splicing points. The upper surface of the base plate 1 is provided with support components 3, which provide stable support for the steel truss floor deck, enhance the overall load-bearing capacity and rigidity of the floor deck, and ensure its stability and safety during construction and use.

[0024] Reference Figures 1-3The support component 3 includes a support base 31. As the core component of the support component 3, the support base 31 provides the main support for the floor decking, bearing the weight of the floor decking and the concrete above it, and transferring the load to the base plate 1 and the supporting structure below. The support base 31 is detachably connected to a groove on the upper surface of the base plate 1 via fixing bolts 32. The fixing bolts 32 facilitate the installation and removal of the support base 31, allowing for flexible adjustment of the support structure under different construction stages or application scenarios. A vertical groove 33 is formed at the axial center of the upper surface of the support base 31. This device can be used to pass through steel trusses or other related components in steel truss floor decks, allowing the steel trusses to be tightly integrated with the support base 31, enhancing the integrity and load-bearing capacity of the floor deck. Simultaneously, after concrete pouring, the steel trusses can form a good anchorage effect with the concrete, improving the shear resistance of the floor deck. Transverse grooves 34 are provided at both the front and rear ends of the left surface of the support base 31. Multiple sets of evenly distributed ball bearings 35 are rolled within the inner walls of these grooves, reducing friction with contacting objects and making the support structure more flexible, facilitating the adjustment of the floor deck during construction. The system allows for adjustment and movement, while also accommodating minor deformations of the floor decking during use, ensuring the stability and reliability of the support. Multiple sets of evenly distributed ball bearings 35 are rolled within the inner wall of the transverse groove 34. A base rod 36 is fixedly installed on the upper surface of the base plate 1, penetrating and connecting to the outer wall of the support base 31. The base rod 36 serves as the basic support component of the support assembly 3, forming a stable support structure together with the support rod 38 and top rod 37. This effectively disperses the pressure on the floor decking, enhances its load-bearing capacity, and ensures the stability and safety of the floor decking during construction and use. The outer wall of the base rod 36 is connected via a support... The support rod 38 is welded with a top rod 37. The top of the support rod 38 is fixedly installed on the outer wall of the top rod 37. The top of the top rod 37 is fixedly connected to the support rod 38, and the bottom is connected to the bottom rod 36. Together, they form a stable support structure, which plays an important supporting role for the floor decking. It can effectively distribute the pressure on the floor decking and improve the load-bearing capacity and rigidity of the floor decking. The bottom of the support rod 38 is fixedly installed on the outer wall of the bottom rod 36. The support rod 38 serves to connect and support the top rod 37 and the bottom rod 36, making the entire support structure more stable and effectively distributing the pressure on the floor decking, thereby enhancing the load-bearing capacity and stability of the floor decking.

[0025] Reference Figures 1-3The assembly component 2 includes an assembly block 22, which is fixedly connected to the right surface of the base plate 1. An assembly groove 21 is provided on the left surface of the base plate 1. The assembly block 22 is slidably connected to the inner wall of the assembly groove 21. The assembly block 22 and the assembly groove 21 work together to expand the assembly of the equipment, so that multiple base plates 1 can be tightly connected together to form an integral floor deck structure. Two sets of positioning grooves 23 are provided on the front surface of the base plate 1, and two sets of positioning blocks 24 are fixedly connected to the rear surface of the base plate 1. The positioning blocks 24 are engaged in the inner wall of the positioning grooves 23. The positioning blocks 24 and the positioning grooves 23 cooperate with each other to play a positioning and fixing role, ensuring that the position of the assembled base plates 1 is accurate and stable and that there is no relative displacement.

[0026] Working principle: During the construction preparation stage, each base plate 1 is quickly assembled using the assembly components 2. Specifically, the assembly block 22 on the right surface of one base plate 1 is inserted into the assembly groove 21 on the left surface of another base plate 1, while the positioning block 24 on the rear surface of the base plate 1 is inserted into the positioning groove 23 on the front surface of the front base plate 1, thereby achieving rapid assembly of the base plates 1 and forming a large-area floor deck structure.

[0027] After assembly, the support component 3 is installed onto the base plate 1, and the fixing bolts 32 are screwed into the support seat 31, fixing the support seat 31 in the groove on the upper surface of the base plate 1. At this time, the vertical groove 33 on the support seat 31 is aligned with the steel truss or other related components in the steel truss floor slab, allowing them to pass through the vertical groove 33, so that the steel truss is tightly connected to the support seat 31. At the same time, in the transverse groove 34 on the left surface of the support seat 31, the ball bearings 35 can reduce the friction between the support and the contacting object, making the support structure more flexible.

[0028] The bottom rod 36 on the upper surface of the base plate 1 passes through the outer wall of the support base 31. The outer wall of the bottom rod 36 is welded with the top rod 37 through the support rod 38. The top of the support rod 38 is fixed to the outer wall of the top rod 37, and the bottom is fixed to the outer wall of the bottom rod 36. The bottom rod 36, the support rod 38 and the top rod 37 form a stable support structure, which enhances the overall load-bearing capacity and rigidity of the floor deck.

[0029] Finally, concrete pouring is carried out. The concrete encapsulates the steel truss in the steel truss floor deck, creating a good anchorage between the steel truss and the concrete, thus improving the shear resistance of the floor deck. After the concrete hardens, the steel truss floor deck and the concrete become a unified whole, forming part of the building's floor slab. During subsequent use, support component 3 continuously bears the weight of the floor deck and the concrete above it, transferring the load to the base slab 1 and the supporting structure below, ensuring the stability and safety of the floor deck. Simultaneously, assembly component 2 ensures the stability and reliability of the joints, preventing misalignment or loosening at the joints.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
