Description

Technical Field

[0001] The utility model patent belongs to the field of engineering construction technology, and specifically relates to a T-beam flange plate hoisting protection device. Background Art

[0002] In the construction of highways and urban roads, T-beams are increasingly used in bridge engineering. The flange plate of the T-beam is its important load-bearing part. However, during the construction and hoisting of the T-beam, wire ropes are often used to hold the T-beam body for hoisting. Since the edge of the flange plate of the T-beam is a protrusion, the wire rope is bent, squeezed and rubbed at a large angle at the edge of the flange plate. Therefore, after hoisting, the edge of the flange plate of the T-beam will have serious wear marks, and serious pits will occur, which seriously affects the quality of the T-beam; at the same time, the wire rope is worn, and its service life is greatly reduced, which increases the construction cost. If the wire rope is used for a long time, safety accidents may also occur.

[0003] During on-site construction, construction workers usually use hard materials such as steel plates or wooden boards to support the edges of T-beam flange plates as protective devices. However, the protective materials are easily damaged when subjected to impact and cannot effectively absorb impact energy. The protective effect on the edges of T-beams is limited, and the actual use effect is poor. Summary of the invention

[0004] The utility model provides a T-beam flange plate hoisting protection device, which is used for the hoisting construction of T-beams, effectively protects the edges of the T-beam flange plates, and can be applied to T-beam flange plates of various thicknesses. It is easy to use and has a wide range of applications, greatly improving the T-beam hoisting construction efficiency and improving the project quality.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A T-beam flange plate hoisting protection device comprises an upper L-shaped corner guard and a lower L-shaped corner guard. Vertical bolt limiting grooves are arranged on both sides of the lower L-shaped corner guard, bolt through holes are arranged at corresponding positions of the upper L-shaped corner guard, fastening bolts pass through the bolt limiting grooves and the bolt through holes, nuts A and nuts B are arranged on the fastening bolts to anchor and fix the upper L-shaped corner guard and the lower L-shaped corner guard; two vertical plates are arranged in the middle of the lower L-shaped corner guard to form a vertically penetrating wire rope through groove.

[0007] The horizontal parts of the upper L-shaped corner guard and the lower L-shaped corner guard clamp the upper and lower end faces of the T-beam flange plate in opposite directions, and then the upper and lower corner guards are fixed and anchored with bolts to form a protective layer wrapped around the edge of the T-beam flange plate. The wire rope groove directly contacts the wire rope to be compressed and limited, avoiding the wire rope from being damaged by direct friction with the edge of the flange plate. The relative position of the upper L-shaped corner guard and the lower L-shaped corner guard can be adjusted up and down to achieve the clamping of flange plates of different thicknesses.

[0008] The steel wire rope through groove is provided with a U-shaped buckle which can limit the position of the steel wire rope and prevent the steel wire rope from slipping out of the through groove.

[0009] The inner side of the horizontal part of the upper L-shaped corner guard is provided with a rubber pad A, and the inner side of the horizontal part of the lower L-shaped corner guard is provided with a rubber pad B. The rubber pad directly contacts the flange plate to prevent the steel plate from directly crushing the flange plate and plays an anti-slip role.

[0010] Vertical steel bar grooves are arranged at positions corresponding to the upper L-shaped corner guard and the lower L-shaped corner guard. The steel bar grooves are used to pass the embedded steel bars exposed outside the flange plate.

[0011] The steel wire rope groove and the steel wire rope contact surface are pasted with a rubber pad, which is used to reduce the damage caused by the friction between the steel wire rope and the steel wire rope groove.

[0012] An inner rubber pad is arranged in the middle of the contact surface between the upper L-shaped corner guard and the T-beam flange plate, and the thickness of the inner rubber pad is greater than the thickness of the nut B. The inner rubber pad prevents the nut B from pressing on the surface of the flange plate and causing damage to the flange plate.

[0013] Advantages of utility models

[0014] 1. The utility model has a simple structure and is easy to operate. It can ensure that the flange plate of the T-beam is not damaged during the hoisting process. Therefore, it can reduce the later repair and maintenance costs of the T-beam, improve the construction quality, and have greater economic benefits.

[0015] 2. This utility model patent is easy to operate and suitable for use on construction sites. Through stable and firm lifting protection, it reduces the friction between the wire rope and the flange plate, avoids the problems of accidental slipping and damage of the flange plate during the lifting process, and ensures the personal safety of construction workers and the quality of the project.

[0016] 3. The utility model can also be applied to beams with other cross-section shapes, such as I-beams, etc., and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS
