Steel beam lifting fastening type special clamp

Abstract

The invention discloses a steel beam lifting fastening type special clamp, and belongs to the field of engineering lifting tools. The steel beam lifting fastening type special clamp comprises a supporting and lifting component, a pressing and adjusting plate, a lifting lug and a bolt, wherein the supporting and lifting component is a structural body with two orthogonal connection plate bodies, a through hole is formed in a horizontal plate body of the two plate bodies, the lifting lug for lifting the through hole is arranged at the upper end of a vertical plate body of the two plate bodies, and an adjusting through hole is formed in the vertical plate body below the lifting lug; a through hole is formed in the pressing and adjusting plate, and the rear end of the pressing and adjusting plate is an adjusting and limiting part matched with the adjusting through hole of the vertical plate body of the supporting and lifting component; the adjusting and limiting part of the pressing and adjusting plate is movably arranged in the adjusting through hole of the vertical plate body of the supporting and lifting component, and space between the pressing and adjusting plate and the horizontal plate body of the supporting and lifting component is a clamping space; the bolt penetrates through the through hole of the pressing and adjusting plate and the through hole of the horizontal plate body of the supporting and lifting component. According to the steel beam lifting fastening type special clamp disclosed by the invention, the lifting lug is arranged at the upper end of the supporting lifting component, and the lifting lug is not under a lateral force in a steel beam lifting process, so that the deformation of the clamp is avoided, the safety is improved, and the reutilization is facilitated.

Description

technical field [0001] The invention relates to the field of building construction hangers, in particular to a special clamp for hoisting and fastening steel beams. Background technique [0002] When carrying out on-the-spot steel beam hoisting in existing engineering, majority is to adopt hoisting snap ring to cooperate with the hoisting hole on the steel beam, and hoisting snap ring passes hoisting hole, and steel wire rope passes hoisting snap ring to hoist steel beam then. Although this method of using a snap ring is simple and effective, according to the specification, the hoisting snap ring is not allowed to be subjected to lateral force, so there is a potential safety hazard. Because the snap ring is subject to lateral force, it will become easily deformed during the hoisting process, which affects the number of repeated uses, and does not meet the requirements of the existing operating specifications. Contents of the invention [0003] The technical problem to be ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a special clamp for hoisting and fastening of steel beams, which can be conveniently clamped on the flanges of steel beams of different thicknesses, avoiding the lateral force on the clasps of the traditional hoisting method, which will cause the clasps to be in the hoisting position. The problem of deformation during the process improves the safety and also enables the fixture to be reused in construction
