Building outer wall steel structure positioning fine adjustment self-adaptive fixing device and method

The steel structure is automatically adjusted to a vertical position by using a lifting frame and vibration sensors, and the steel structure is precisely positioned and stably clamped by using locking and hydraulic units. This solves the problem that existing devices cannot adjust the shape and determine the vertical position on their own, thus improving installation accuracy and stability.

AI Technical Summary

Technical Problem

Existing steel structure welding clamping devices cannot adjust the structural shape according to usage needs, cannot quickly connect steel structure raw materials, and cannot determine the vertical state of the steel structure on their own. They are cumbersome to operate and are prone to tilting on uneven ground.

Method used

Using a lifting frame and vibration sensors, the steel structure is automatically adjusted to a vertical position through a rotating ball and clamping unit in a rotating slot, and fixed with a locking unit. Combined with a hydraulic unit, a constant clamping force is provided to ensure the precise positioning and stable clamping of the steel structure.

Benefits of technology

It improves the accuracy and stability of steel structure installation, avoids tilting caused by uneven ground, simplifies the connection process, and improves work efficiency.

Abstract

This invention relates to the field of exterior wall steel structure fixing technology, specifically to a self-adaptive fixing device and method for fine-tuning the positioning of building exterior wall steel structures. The device includes a support frame; an adjustment unit on the support frame for adjusting the spatial state of the steel structure; the adjustment unit includes a lifting frame that moves along the height direction of the support frame; a rotating groove is formed at the center of the lifting frame; a rotating ball is rotatably arranged within the rotating groove; a through groove is formed through the rotating ball; and a clamping unit is arranged in the through groove to vertically clamp the steel structure. The distance from the upper end of the steel structure to the clamping unit is less than the distance from the lower end of the steel structure to the clamping unit. A vibration sensor on the lifting frame detects the vibration generated when the rotating ball rotates in conjunction with the lifting frame. This invention improves the accuracy of the steel structure during installation and avoids tilting of the fixing device due to uneven ground.
