Description

Technical Field

[0001] This utility model belongs to the field of floor decoration, and specifically relates to a side-inserted shock-absorbing anchor bolt for raised floors. Background Technology

[0002] Elevated ground is a building technology that uses a supporting structure to raise the ground to form a cavity layer. It is widely used in data centers, office buildings, laboratories, industrial plants and other scenarios to achieve functions such as pipeline concealment, ventilation and heat dissipation, moisture protection and anti-static properties.

[0003] The existing technology can be referenced in patent CN220580419U, which discloses a prefabricated elevated ground system. The pressure plate is fixed to the ground by anchor bolts, which include bolts and shock-absorbing and sound-insulating pads. The anchor bolts have through holes for injecting glue, which flows through the bolts and shock-absorbing and sound-insulating pads to the ground for fixation.

[0004] However, in actual construction, the wrap-around vibration damping and sound insulation pads often detach from the supporting bolts, while the side-inserted vibration damping and sound insulation pads are prone to uneven distribution of the foam adhesive, resulting in increased adhesive usage and worse environmental performance. Utility Model Content

[0005] This utility model provides an overhead ground side-insertion shock-absorbing anchor bolt to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a side-inserted vibration-damping anchor bolt for elevated ground, comprising a nut, a screw, an anti-loosening washer, and a vibration-damping and sound-insulating pad. The nut is threaded onto the screw and has a bearing ring. The bottom end of the screw has a base plate with a diameter larger than the screw. The top of the vibration-damping and sound-insulating pad has a circular groove one that mates with the screw and a circular groove two that mates with the base plate. The screw passes through the vibration-damping and sound-insulating pad from the circular groove one. The side end of the vibration-damping and sound-insulating pad has... There is a side insertion hole connected to the second circular groove. The width of the side insertion hole is the same as the diameter of the base plate. The top of the shock-absorbing and sound-insulating pad located in the middle of the side insertion hole has a side insertion anti-detachment gap with a width smaller than the diameter of the screw and for the screw to pass through. Anti-detachment blocks are formed on both sides of the side insertion anti-detachment gap. The anti-detachment pad is set on the top of the shock-absorbing and sound-insulating pad. The anti-detachment pad includes a circular plate located on the shock-absorbing and sound-insulating pad, a gap insert that cooperates with the side insertion anti-detachment gap, and a side insertion hole insert that cooperates with the side insertion hole. The circular plate is fitted on the screw.

[0007] By adopting the above technical solution, this application uses a side-insertion method, which solves the problem of the shock-absorbing and sound-insulating pad falling off the screw. It also adds an anti-fall-off gasket to seal the leaking part of the shock-absorbing and sound-insulating pad, ensuring that the micro-foamed adhesive inside the hollow screw is smoothly and evenly distributed to the floor slab through the bottom of the screw, ensuring consistent product quality. Through reasonable design and optimized material selection, this structure is designed with irregularly shaped rubber shock-absorbing pads with side openings and irregularly shaped anti-fall-off gaskets, ensuring the stability and load-bearing capacity of the anchor bolt structure. The standardized design makes the installation of the anchor bolts simpler and faster, reducing construction difficulty and cost.

[0008] Preferably, the side-insertion anti-detachment slot is conical, with the end closer to the screw being smaller than the end farther from the screw.

[0009] By adopting the above technical solution, the screw can be easily inserted.

[0010] Preferably, the included angle of the arc corresponding to the end of the side-insertion anti-detachment seam near the screw is 60°-70°.

[0011] By adopting the above technical solution, the shock-absorbing and sound-insulating pads can surround more than half of the screw, thus preventing it from falling off.

[0012] Preferably, the bottom end of the connection between the anti-detachment block and the shock-absorbing and sound-insulating pad on one side has a slit.

[0013] By adopting the above technical solution, when the anti-detachment pad falls, the anti-detachment block can be pried up, so that the side insertion hole insert can be inserted into the side insertion hole first. After the anti-detachment block is put down, the gap insert is sealed at the side insertion anti-detachment gap, so that the whole is completely sealed.

[0014] Preferably, the top of the shock-absorbing and sound-insulating pad has several extrusion cavities evenly distributed.

[0015] By adopting the above technical solution, the shock-absorbing and sound-insulating pad has compressible elasticity, which makes it easier for the screw and the base plate to be squeezed into the first and second circular grooves.

[0016] Preferably, the bottom end of the shock-absorbing and sound-insulating pad has a cross-shaped groove.

[0017] By adopting the above technical solution, the injected adhesive can be evenly distributed and bonded, resulting in a better fixing effect.

[0018] The beneficial effects of this utility model are as follows: This application adopts a side-insertion method, which solves the problem of the shock-absorbing and sound-insulating pad falling off the screw. It also adds an anti-fall-off gasket to seal the leakage part of the shock-absorbing and sound-insulating pad, ensuring that the micro-foamed adhesive inside the hollow screw is smoothly and evenly distributed to the floor slab through the bottom of the screw, ensuring consistent product quality. Through reasonable design and optimized material selection, this structure includes a special-shaped rubber shock-absorbing pad with a side opening and a special-shaped anti-fall-off gasket, ensuring the stability and load-bearing capacity of the anchor bolt structure. The standardized design makes the installation of the anchor bolts simpler and faster, reducing construction difficulty and cost.

[0027] The technical solution of this utility model will be described in detail below through embodiments. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of this utility model, and should not be construed as limiting the technical solution of this utility model.

[0028] Combination Figure 1-6 A type of ground-mounted side-insertion vibration-damping anchor bolt includes a nut 1, a screw 2, an anti-loosening washer 3, and a vibration-damping and sound-insulating pad 4. The nut 1 is threaded onto the screw 2 and has a bearing ring 5. The bottom end of the screw 2 has a base plate 6 with a diameter larger than that of the screw 2. The top of the vibration-damping and sound-insulating pad 4 has a circular groove 7 that mates with the screw 2 and a circular groove 8 that mates with the base plate 6. The screw 2 passes through the circular groove 7 and exits the vibration-damping and sound-insulating pad 4. The side end of the vibration-damping and sound-insulating pad 4 has a side insertion hole 9 that communicates with the circular groove 8. The width of 9 is the same as the diameter of the base plate 6. The top of the side insertion hole 9 of the shock-absorbing and sound-insulating pad 4 has a side insertion anti-detachment gap 10 with a width smaller than the diameter of the screw 2 and for the screw 2 to pass through. Anti-detachment blocks 11 are formed on both sides of the side insertion anti-detachment gap 10. The anti-detachment pad 3 is set on the top of the shock-absorbing and sound-insulating pad 4. The anti-detachment pad 3 includes a circular plate 12 located on the shock-absorbing and sound-insulating pad 4, a gap insert 13 that cooperates with the side insertion anti-detachment gap 10, and a side insertion hole insert 14 that cooperates with the side insertion hole 9. The circular plate 12 is fitted on the screw 2.

[0029] This application adopts a side-insertion method, which solves the problem of the shock-absorbing and sound-insulating pad falling off from the screw 2. It also adds an anti-fall-off gasket 3 to seal the glue leakage part of the shock-absorbing and sound-insulating pad 4, ensuring that the micro-foamed glue inside the hollow screw 2 can be smoothly and evenly distributed to the floor slab through the bottom of the screw 2, ensuring consistent product quality. Through reasonable design and optimized material selection, this structure is designed with a special-shaped rubber shock-absorbing pad with a side opening and a special-shaped anti-fall-off gasket 3, ensuring the stability and load-bearing capacity of the anchor bolt structure. The standardized design makes the installation of the anchor bolts simpler and faster, reducing construction difficulty and cost.

[0030] The side-insertion anti-loosening seam 10 is tapered, with the end closer to the screw 2 being smaller than the end farther from the screw 2, making it easy for the screw 2 to be inserted.

[0031] The included angle of the arc corresponding to the end of the side-insertion anti-detachment seam 10 near the screw 2 is 60°-70°, so that the shock-absorbing and sound-insulating pad 4 surrounds more than half of the screw 2, which can prevent it from falling off.

[0032] One of the anti-detachment blocks 11 has a slit 15 at the bottom of the connection between it and the shock-absorbing and sound-insulating pad 4. When the anti-detachment pad 3 falls, it can bend the anti-detachment block 11 up, so that it can first pass through the unbent end of the side insertion hole insert 14, allowing the side insertion hole insert 14 to enter the side insertion hole 9. After the anti-detachment block 11 is put down, the slit insert 13 seals the side insertion anti-detachment slit 10, thus sealing the entire part.

[0033] The top of the vibration damping and sound insulation pad 4 has several extrusion cavities 16 evenly distributed, which gives the vibration damping and sound insulation pad 4 the elasticity to be extruded, so that the screw 2 and the base plate 6 can be more easily extruded into the circular groove 7 and the circular groove 8.

[0034] The bottom of the shock-absorbing and sound-insulating pad 4 has a cross-shaped adhesive groove 17, which can make the injected adhesive evenly distributed and bonded, resulting in a better fixing effect.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
