Description

Technical Field

[0001] This utility model relates to the field of steel truss floor decking technology, specifically an impact-resistant steel truss floor decking. Background Technology

[0002] The pressed steel sheet that supports the concrete floor is called profiled steel sheet, also known as floor deck or steel deck. It is widely used in power plants, power equipment companies, car showrooms, steel structure workshops, cement warehouses, steel structure offices, and steel structure buildings for airport terminals.

[0003] The existing floor decking has been galvanized to seal its rust-proof and anti-rust surface and prevent oxidation and corrosion in the air. The use of galvanized floor decking can significantly improve the rigidity of the floor slab.

[0004] However, existing truss floor decks are subjected to tremendous impact forces from external factors during normal use, which can easily cause the entire truss floor deck to crack and affect its service life. To address the above problems, an impact-resistant steel truss floor deck is proposed. Utility Model Content

A nut is fixedly connected through the top of the second connecting plate. A threaded rod is threadedly connected to the inner ring of the nut. A square groove is opened at the top of the threaded rod. A square block is slidably connected to the inner wall of the square groove. A limit ring is rotatably connected to the bottom of the threaded rod. An insert is fixedly connected to the bottom of the limit ring. First limit plates are fixedly connected to both the front and rear sides of the insert. A first connecting plate is fixedly connected to the left side of the base.

[0016] As a further description of the above technical solution: the first connecting plate has a slot at its top, and the second connecting plate is slidably connected to the inner wall of the first connecting plate.

[0017] By adopting the above technical solution, the splicing of the floor decking is achieved when the first connecting plate and the second connecting plate are spliced ​​together.

[0018] As a further description of the above technical solution: the inner wall of the slot is slidably connected to a plug block, and the inner wall of the slot is slidably connected to a first limiting plate.

[0023] 1. This utility model provides an impact-resistant steel truss floor deck. Through connecting rods, slip rings, support rods, and spring dampers, when the floor deck body is subjected to impact force, the second limiting plate slides in the groove, which will squeeze the support plate. Then the support rod is stressed, causing the slip ring to slide on the connecting rod, which then squeezes the spring. When the impact force decreases, the spring will rebound. Together with the placed spring dampers, they work to reduce the impact force, reduce the overall cracking of the floor deck, and improve its service life.

[0024] 2. The present invention provides an impact-resistant steel truss floor deck, which consists of a first connecting plate, a second connecting plate, a first limiting plate, an insert block, and a threaded rod. The first connecting plate is placed inside the first connecting plate, and then a square block is inserted into the square groove. Then, the knob is turned to drive the threaded rod to rotate in the nut, so that the insert block moves from the moving groove into the slot and completes the splicing in the slot. After the splicing is completed, the knob is removed and stored to prevent the connection of the floor deck from loosening. Attached Figure Description

[0034] Combination Figure 1 and Figure 2 This utility model discloses an impact-resistant steel truss floor deck, comprising a base 1, a floor deck body 2 on top of the base 1, and two second limiting plates 14 fixedly connected to the bottom of the floor deck body 2. When the second limiting plates 14 are subjected to force, they will slide within a groove 15. A support plate 22 is also provided with a second limiting plate 14 on top, and a spring damper 16 is also provided with a second limiting plate 14 on top to absorb force. The second limiting plates 14 are slidably connected to the grooves 15. A knob 5 is fixedly connected to the top of a square block 6. When the knob 5 is not in use, it is necessary to... The knob 5 is stored for easy use when dismantling the floor deck. The top of the first connecting plate 3 has a slot 13. When the insert 9 moves into the slot 13, the first connecting plate 3 can be fixed. The inner wall of the second connecting plate 4 is slidably connected to the first connecting plate 3. The inner wall of the slot 13 is slidably connected to the insert 9. The inner wall of the slot 13 is slidably connected to the first limiting plate 10. The top of the inner wall of the second connecting plate 4 has a moving groove 25. When dismantling the floor deck, the moving groove 25 provides a certain amount of space for the insert 9 to move. The inner wall of the moving groove 25 is slidably connected to the insert 9.

[0035] Combination Figure 3 and Figure 6The base 1 has two grooves 15 on its top. The bottom of the inner wall of the two grooves 15 is fixedly connected to evenly distributed fixed plates 17. A connecting rod 18 is placed between the fixed plates 17. The connecting rod 18 is used to limit the movement of the slip ring 19. A connecting rod 18 is fixedly connected between two adjacent fixed plates 17. Two slip rings 19 are slidably connected to the outer ring of the connecting rod 18. When the support rod 21 is subjected to force, it will rotate, thereby driving the slip ring 19 to move. Two springs 20 are sleeved on both sides of the outer ring of the connecting rod 18. The top of the two adjacent slip rings 19 is rotatably connected to the support rod 21. When the slip ring 19 moves, it will squeeze the spring 20. When the impact force decreases, the spring 20 will rebound. A rotating plate 24 is fixedly connected to one end of the two slip rings 19. A U-shaped plate 23 is rotatably connected to one side of the two rotating plates 24. A support plate 22 is fixedly connected to the top of the U-shaped plate 23. Two spring dampers 16 are provided at the bottom of the inner wall of the two grooves 15. A splicing assembly is provided on the right side of the base 1.

[0036] Combination Figure 4 and Figure 5 The splicing assembly includes a second connecting plate 4, which is fixedly connected to the base 1. A nut 8 is fixedly connected through the top of the second connecting plate 4. A block 6 is inserted into a square groove 7 for positioning. A threaded rod 12 is threadedly connected to the inner ring of the nut 8. When the knob 5 is turned, the threaded rod 12 can be rotated. The threaded rod 12 rotates within the nut 8. A square groove 7 is opened at the top of the threaded rod 12. A square block 6 is slidably connected to the inner wall of the square groove 7. A limiting ring 11 is rotatably connected to the bottom of the threaded rod 12. An insert 9 is fixedly connected to the bottom of the limiting ring 11. Rotating the threaded rod 12 can move the insert 9. A first limiting plate 10 is fixedly connected to both the front and rear sides of the insert 9. A first connecting plate 3 is fixedly connected to the left side of the base 1.

[0037] Working principle: When using floor decking, when the floor decking body 2 is subjected to impact force, the second limiting plate 14 will slide downward in the groove 15, then the support plate 22 will be stressed, which will press the support rod 21, causing the slip ring 19 to slide on the connecting rod 18, and then compressing the spring 20. When the impact force decreases, the spring 20 will rebound, and at the same time the spring damper 16 will also work to reduce the impact force and improve the service life of the floor decking. Then, when splicing floor decking, another floor decking can be connected to the first connecting plate. Plate 3 is slid into the second connecting plate 4. Then, knob 5 is removed, and square block 6 is inserted into square groove 7. Rotating knob 5 will cause threaded rod 12 to rotate in nut 8, causing insert 9 to move. Then, insert 9 moves from moving groove 25 into slot 13 to limit the first connecting plate 3. At the same time, first limiting plate 10 also moves within slot 13 to limit the movement of the connecting plate, preventing the connection of the floor deck from becoming loose. After the splicing is completed, knob 5 is removed and stored to prevent accidental contact with threaded rod 12.
