[0021] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0022] Referring to Figures 1-5 , an embodiment of a steel - bar truss floor slab of the present utility model includes: a bottom plate 1. Auxiliary connection mechanisms 16 are arranged at both the left and right ends of the upper surface of the bottom plate 1. The auxiliary connection mechanism 16 is composed of a card slot 7 and a connection buckle 9. When docking the truss floor slabs, the lower ends of the connection buckles 9 are respectively located inside the card slots 7 of the two floor slabs. The auxiliary connection mechanism 16 improves the convenience during the docking and reinforcement of multiple truss floor slabs by means of clamping. A storage groove 8 is arranged on the upper surface of the bottom plate 1, and the connection buckle 9 is located inside the storage groove 8. The storage groove 8 improves the stability when the connection buckle 9 functions and ensures that the height of the upper surface of the connection buckle 9 is the same as the height of the upper surface of the bottom plate 1, improving the flatness of the bottom plate 1.

[0023] On the upper surface of the bottom plate 1, there are two fixed covers 2 and a truss body 4. The fixed covers 2 are slidably connected to the bottom plate 1. On the opposite sides of the two fixed covers 2, there is a docking mechanism 6. The lower end of the truss body 4 is located inside the fixed cover 2. The docking mechanism 6 is composed of a docking plate 14 and a docking groove 15. The docking plate 14 is fixedly connected to the front fixed cover 2, and the front end of the docking plate 14 penetrates into the docking mechanism 6 inside the front fixed cover 2. The docking mechanism 6 utilizes the clamping friction between the docking plate 14 and the docking groove 15 to improve the stability after the two fixed covers 2 are combined. On the surface of the fixed cover 2, there are multiple openings 3. The diameter of the openings 3 is the same as the diameter of the steel bars of the truss body 4. The openings 3 improve the convenience of using the fixed cover 2. At the position near the opening 3 on the lower inner wall of the fixed cover 2, there is a partition plate 17 fixedly connected. The lower surface of the partition plate 17 is in close contact with the upper surface of the reinforcing plate 5. The partition plate 17 prevents a large amount of foreign objects from entering the inside of the fixed cover 2 through the opening 3, ensuring that the gap between the fixed cover 2 and the reinforcing plate 5 will not be filled with foreign objects.

[0024] The lower end of the truss body 4 is fixedly connected with a reinforcing plate 5. The upper surface of the reinforcing plate 5 is not in contact with the upper inner wall of the fixed cover 2. The reinforcing plate 5 and the fixed cover 2 cooperate with each other to facilitate the integration of the truss body 4 and the bottom plate 1. The gap between the reinforcing plate 5 and the fixed cover 2 provides conditions for the truss body 4 to disperse local stress, reducing the influence of earthquakes, thermal expansion and contraction on the structure of the steel bar truss floor slab itself. Inside the fixed cover 2, there are multiple pressing plates 11. The upper and lower surfaces of the pressing plates 11 are respectively in close contact with the inner wall of the fixed cover 2 and the upper surface of the reinforcing plate 5. The pressing plates 11 improve the stability of the reinforcing plate 5 inside the fixed cover 2. By restricting the movement range of part of the reinforcing plate 5, the stability and bearing capacity of the truss body 4 are improved.

[0025] On the surface of the fixed cover 2, there are multiple reinforcement mechanisms 10. The reinforcement mechanism 10 is composed of screws 12 and screw holes 13. Screw holes 13 are provided on the front and rear sides of the fixed cover 2, the docking plate 14, the pressing plates 11, the reinforcing plate 5, and the bottom plate 1. Neither the pressing plate 11 nor the bottom plate 1 is penetrated by the screw holes 13. The screws 12 cooperate with some of the screw holes 13 in a certain state to achieve the effect of fixing the pressing plate 11 and the docking plate 14 and strengthening the fixed cover 2. That is, some screws 12 penetrate the fixed cover 2, the docking plate 14 and are threadedly connected with the pressing plate 11, and some screws 12 penetrate the fixed cover 2 and are directly threadedly connected with the bottom plate 1.

[0026] Working principle: The reinforcing plate 5 and the fixed cover 2 cooperate with each other to provide stability for the truss body 4. Since the thickness of the reinforcing plate 5 is less than the height of the inner wall space of the fixed cover 2, a space for dispersing stress is provided when the truss body 4 is subjected to negative stress, reducing the situation of local stress concentration, thereby reducing the influence of earthquakes, thermal expansion and contraction on the stability of the components of the steel bar truss floor slab itself. The pressing plate 11 and the reinforcement mechanism 10 cooperate with each other to improve the stability of the reinforcing plate 5 inside the fixed cover 2, thereby preventing the reinforcing plate 5 from moving excessively inside the fixed cover 2.

[0027] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
