Steel structure hoisting device for building construction

Abstract

The invention provides a steel structure hoisting device for building construction, which comprises a metal sleeve and a C-shaped rod, the lower part of the metal sleeve fixedly sleeves the upper end of a steel cable, the lower end of the steel cable is fixedly provided with a hook, the lower part of the metal sleeve is fixedly connected with the upper end of the C-shaped rod, the lower end of the C-shaped rod is provided with a fixed block, and the middle upper part of the C-shaped rod is sleeved with another fixed block; the fixing blocks can move up and down on the C-shaped rod, and the front end of each fixing block is provided with a fixing ring which can be opened and closed and can adjust the size of the fixing ring. According to the steel structure hoisting device, a steel structure can be conveniently fixed, the space in the C-shaped fixing ring can be properly adjusted according to the size of the steel structure, the application range of equipment is increased, the practicability is improved, the fixing blocks are fixed to the long-strip-shaped grooves in a meshed mode through the arrangement of the fixing blocks and the square blocks, and when some long steel structures are hoisted, the fixing blocks can be adjusted, so that the hoisting efficiency is improved. Gaps between the fixing blocks are increased, the bearing range of the gravity of the steel cable is enlarged, and working safety is improved.

Description

technical field [0001] The invention belongs to the field of building technology, and in particular relates to a steel structure hoisting device for building construction. Background technique [0002] With the continuous development of my country's infrastructure construction technology, more and more steel structures are widely used in various fields. When constructing existing large-scale steel structure buildings, it is necessary to lay multiple steel columns on the bottom. The role is to support the entire steel structure, so these steel columns are usually large in volume and quality. When installing these steel columns, they are installed by hoisting equipment. After the steel column is hoisted, it is necessary to align these through holes with the pre-installed bolts on the ground, and then tighten the bolts to fix the steel column to the ground. [0003] Most of the original steel structure hoisting devices for building construction use steel cables to wind the tubul...

AI Technical Summary

Problems solved by technology

[0003] Most of the original steel structure hoisting devices for building construction use steel cables to wind the tubular steel structure and transport it through the hoist. It is easy to receive uneven force or even slip, and the quality of the steel structure is very large. When the steel cable is hoisted, the steel structure will inevitably shake, which has a great impact on the bearing capacity of the steel cable, so there is a high risk
