Description

Technical Field

[0001] This utility model relates to the field of steel truss floor decking technology, and in particular to a steel truss floor decking. Background Technology

[0002] A steel truss floor slab is a prefabricated floor slab structure composed of a precast steel truss and a floor slab. Its core part uses upper and lower chord steel bars and web members welded into a stable triangular truss, which can serve as formwork support during the construction phase and also share the loads with the concrete during the service phase.

[0003] After the steel truss floor decking is laid, adjacent decking plates need to be firmly joined by welding to ensure that the welds are full and free of defects such as slag inclusions or undercut, so as to ensure the integrity of the floor decking and its load transfer performance.

[0004] During the assembly of steel truss floor decking, gaps of varying degrees often appear between adjacent precast panels, forcing operators to manually apply force to ensure tight bonding between the panels. This remedial operation significantly increases the difficulty of welding operations and causes inconvenience to construction workers. Therefore, a steel truss floor decking is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a steel truss floor deck, which aims to improve the problem mentioned in the prior art that "the assembly gap of the steel truss floor deck will cause inconvenience to the welding operation".

[0030] 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.

[0031] Reference Figure 1 - Figure 3 One embodiment of this utility model is a steel truss floor deck, which includes a floor deck body 1 and a steel truss body 2 fixedly installed on its top. The top of the floor deck body 1 is provided with a docking mechanism 3 and a positioning mechanism 4.

[0032] Reference Figure 1 - Figure 3 The docking mechanism 3 includes a boss 31, which is fixedly installed on the top of the floor deck body 1. A rotating rod 32 is rotatably connected through the inner wall of the boss 31. The angle of the pull rod 33 can be adjusted by the rotating rod 32. Two sets of bosses 31 are provided, located at both ends of the rotating rod 32 respectively. The two sets of bosses 31 can support both ends of the rotating rod 32, improving the stability of the rotation of the rotating rod 32. Both ends of the rotating rod 32 are rotatably connected through the inner wall of the boss 31. A pull rod 33 is slidably connected through the inner wall of the rotating rod 32. When the pull rod 33 is rotated, the pull rod 33 will drive the rotating rod 32 to rotate on the inner wall of the boss 31. A connecting rod 34 is fixedly installed on the outer wall of the pull rod 33. A hook 35 is fixedly installed at the end of the connecting rod 34 away from the tie rod 33. The hook 35 is engaged with the outer wall of the steel truss body 2. Rotating the tie rod 33 can drive the hook 35 on the connecting rod 34 to hook the steel truss body 2. A limit block 36 is fixedly installed at the end of the tie rod 33 near the rotating rod 32. A spring 37 is sleeved on the outer wall of the tie rod 33. Pulling the tie rod 33 will cause the limit block 36 to gradually approach the rotating rod 32. At this time, the tie rod 33 will stretch the spring 37. One end of the spring 37 is fixedly installed on the outer wall of the tie rod 33, and the other end of the spring 37 is fixedly installed on the outer wall of the rotating rod 32. Through the elasticity of the spring 37, the tension applied by the tie rod 33 and the connecting rod 34 can make the hook 35 tightly hook the steel truss body 2.

[0033] Reference Figure 1 - Figure 3 The positioning mechanism 4 includes a limiting rod 41, which passes through and slidably connects to the inner wall of the boss 31. A recess 42 for inserting the limiting rod 41 is fixedly installed on the top of the floor deck body 1. After the two sets of floor deck bodies 1 are assembled, the limiting rod 41 slides into the recess 42. The recess 42 is U-shaped, and the outer wall of the limiting rod 41 fits against the inner wall of the recess 42. When the limiting rod 41 enters the recess 42, it will engage the two sets of floor deck bodies 1. Limiting is applied on both the front and rear sides, so that the two sets of floor deck bodies 1 can be kept in a neat docking state. Cams 43 are fixedly installed at both ends of the rotating rod 32. The end of the cam 43 away from the rotating rod 32 is hinged to the connecting rod 44. The end of the connecting rod 44 away from the cam 43 is hinged to the outer wall of the limiting rod 41. When the rotating rod 32 rotates on the inner wall of the boss 31, it will drive the cam 43 to rotate synchronously. Through the rotation of the cam 43 and the connecting rod 44, the limiting rod 41 can be driven to slide on the inner wall of the boss 31.

[0034] Working principle: In use, first assemble the two sets of steel truss floor slabs together, then pull the tie rod 33 to move the limiting block 36 closer to the rotating rod 32. At the same time, the tie rod 33 will stretch the spring 37. Then rotate the tie rod 33 to make the rotating rod 32 rotate on the inner wall of the boss 31. At this time, the tie rod 33 will drive the connecting rod 34 to rotate synchronously until the connecting rod 34 drives the hook 35 to rotate to the inner side of the steel truss body 2. Then the tie rod 33 can be released. At this time, the spring 37 will pull the tie rod 33, so that the tie rod 32 rotates to the inner side of the steel truss body 2. 3. The sliding rod 32 slides on the inner wall and drives the limiting block 36 to gradually move away from the rotating rod 32. At the same time, the pull rod 33 will drive the connecting rod 34 to move synchronously. At this time, the connecting rod 34 will drive the hook 35 to hook the steel truss body 2. Through the elasticity of the spring 37, the pull rod 33 and the connecting rod 34 can make the hook 35 tightly hook the steel truss body 2, so that the two sets of floor deck body 1 can be pressed together, eliminating the assembly gap between the floor deck body 1, so that the workers can weld the floor deck body 1.

[0035] As the tie rod 33 rotates, it drives the connecting rod 34 to gradually approach the steel truss body 2. The rotating rod 32 drives the cam 43 to rotate synchronously. As the cam 43 rotates, it pulls the connecting rod 44, causing the connecting rod 44 to pull the limiting rod 41. At this time, the limiting rod 41 will slide on the inner wall of the boss 31 and gradually approach the concave block 42. After the two sets of floor deck body 1 are assembled, the limiting rod 41 can enter the interior of the concave block 42 as it slides. When the limiting rod 41 enters the interior of the concave block 42, it will limit the front and rear sides of the two sets of floor deck body 1, so that the two sets of floor deck body 1 can maintain a neat docking state, thereby improving the welding quality of the floor deck body 1.

[0036] 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.
