Anti-seismic fire-fighting corrugated pipe for high-rise building

Abstract

This utility model belongs to the field of corrugated pipe technology, specifically disclosing a high-rise building earthquake-resistant fire-fighting corrugated pipe, including a corrugated pipe body. A left fixing plate is fixed to the left side of the corrugated pipe body, and a right fixing plate is fixed to the right side of the corrugated pipe body. A bracket is fixed at the center of the lower right corner of the left fixing plate, and a sleeve is movably connected between the front and rear of the bracket. A bolt is threaded to the front end of the bracket. This high-rise building earthquake-resistant fire-fighting corrugated pipe achieves this by using a sleeve movably connected between the front and rear of the bracket, bending the right side of the corrugated pipe body, rotating the sleeve at the bracket at the lower right corner of the left fixing plate, adjusting the position of the insertion rod from the slot of the sleeve, placing the insertion rod in the groove of the right fixing plate, screwing in a bolt to embed it in the hole on the right side of the insertion rod, and then tightening the insertion rod in the sleeve with a bolt. This forms a support structure between the left and right fixing plates, solving the problem of easy deformation of the corrugated pipe.

Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, specifically to a seismic-resistant fire-fighting corrugated pipe for high-rise buildings. Background Technology

[0002] Corrugated pipes are pipes with overlapping outer layers and expansion and contraction functions. When contracted, the pipe walls fold together, and when expanded, the folds are fully opened. Their length can be adjusted according to usage needs without affecting the flow of gas, liquid, or other materials inside the pipe. They are also commonly used as ventilation ducts in fire protection engineering of high-rise buildings.

[0003] The layout of each building is different. Right-angle pipes are not as convenient to extend and retract as corrugated pipes. They require additional cutting and installation of bend pipes, which is quite cumbersome. However, corrugated pipes often lack a support point after bending, and the bent pipes are easily deformed by external vibrations or their own weight.

[0004] Now, a new type of earthquake-resistant fire-fighting corrugated pipe for high-rise buildings is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a seismic-resistant fire-fighting corrugated pipe for high-rise buildings, so as to solve the problem of easy deformation of corrugated pipes mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-rise building earthquake-resistant fire-fighting corrugated pipe, comprising a corrugated pipe body, a left fixing plate fixed to the left side of the corrugated pipe body, a right fixing plate fixed to the right side of the corrugated pipe body, a bracket fixed to the center of the lower right corner of the left fixing plate, and a sleeve movably connected between the front and rear of the bracket, a bolt two threadedly connected to the front end of the bracket, a slot horizontally provided in the sleeve, and a rod movably inserted into the slot, a hole provided on the right side of the rod, a groove provided inside the bottom end of the right fixing plate, and a bolt four threadedly connected to the lower front end of the right fixing plate.

[0007] As a further technical solution of this utility model, the insertion rod, slot and sleeve are arranged in concentric circles, and the bolts are used to tighten the insertion rod in the sleeve.

[0008] As a further technical solution of this utility model, the right side of the insertion rod is embedded in the groove, and the bolt passes through the groove and the hole.

[0009] As a further technical solution of this utility model, a collar is fixed on the left side of the left fixing plate, and a bolt is threadedly connected to the upper, lower and front and back of the collar. A rubber washer is fixed around the inner wall of the collar, and a circular groove is provided at the center of the collar. A plug ring is fixed on the right side of the right fixing plate, and positioning holes are provided on the upper, lower and front and back of the outer surface of the plug ring.

[0010] As a further technical solution of this utility model, the collar is sleeved on the outside of the plug ring, and the outer surface of the plug ring is in contact with the rubber gasket.

[0011] As a further technical solution of this utility model, the bolt is embedded between the collar and the insertion ring, and the texture of the bolt matches the positioning hole.

[0012] As a further technical solution of this utility model, vertical grooves are provided longitudinally at the front and rear sides of the bottom end of the left and right fixed plates, and a hanging rod is movably inserted into the vertical groove. Mounting holes are arranged between the top and bottom of the hanging rod. Bolts are threadedly connected to the top of the front and rear ends of the left and right fixed plates, respectively. A fixing block is welded to the top of the hanging rod, and a lifting ring is fixed inside the fixing block. A piece is assembled on the top of the lifting ring.

[0013] As a further technical solution of this utility model, the lifting rod slides up and down along the inner wall of the vertical groove, and the rod body of the bolt five is embedded between the vertical groove and the mounting hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the earthquake-resistant fire-fighting corrugated pipe for high-rise buildings not only improves the stability of the corrugated pipe and achieves sealed assembly of pipe interfaces, but also allows for adjustment of the hangers;

[0015] (1) A sleeve is movably connected between the front and rear of the bracket. After pinching the insertion ring and bending the right side of the corrugated pipe body, rotate the sleeve at the bracket at the lower right corner of the left fixed plate. Then adjust the position of the insertion rod from the slot of the sleeve, place the insertion rod in the groove of the right fixed plate, screw in bolt four so that it is embedded in the hole on the right side of the insertion rod, and then use bolt three to press the insertion rod in the sleeve. A support structure can be formed between the left fixed plate and the right fixed plate to prevent the pipe from shaking due to external force.

[0016] (2) By fixing a collar on the left side of the left fixed plate and a plug ring on the right side of the right fixed plate, the left fixed plate of the adjacent pipe is installed at the right fixed plate, so that the plug ring is embedded in the collar with a rubber gasket. The groove in the collar can accommodate the plug ring. After aligning the positioning holes at the top, bottom and front and back, screw in the bolt to fix it. This not only facilitates the assembly of adjacent corrugated pipes, but also prevents liquid or gas leakage.

[0017] (3) By fixing the lifting ring inside the fixed block, pull out the hanging rod in the vertical groove at the front and rear ends above the left and right fixed plates. Select the installation hole according to the height of the pipe to be installed, and then tighten the bolt five on the surface of the left and right fixed plates so that the rod of bolt five is embedded in the installation hole of the hanging rod for locking. Then connect the mounting base with the lifting ring or directly use screws to lock the assembly piece to the ceiling. Adjust the hanging posture according to the different installation positions.
