Special tool convenient for closing gaps of steel plate of steel structure

Abstract

The invention relates to the technical field of steel material gap closure auxiliary tools, in particular to a special tool facilitating steel structure steel plate gap closure, which comprises a U-shaped plate body, an auxiliary plate is fixedly connected to the inner side wall of the U-shaped plate body, and a jack body is arranged on one side of the auxiliary plate. A T-shaped fixing block is arranged on the side, away from the auxiliary plate, of the jack body. And the first gate steel plate is mounted at the bottom end of the left side of the U-shaped plate body. Through mutual cooperation of the jack body, the U-shaped plate body, the auxiliary plate and the T-shaped fixing block, the purpose that welding is convenient after the gap between the first gate steel plate and the second gate steel plate or the large steel plate in the horizontal direction is closed is achieved, it is guaranteed that the whole gate has enough strength and plasticity, welding is easy, the problem that time and labor are wasted is solved, and the working efficiency is improved. And the working efficiency is improved, and the reliability of the equipment is improved by using the hand-cranking jack body.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools for closing gaps of steel materials, in particular to a special tool for closing gaps of steel structural steel plates. Background technique [0002] In the assembly and welding process of steel structures, especially in the assembly and welding of large gates such as hydropower stations and reservoirs or the assembly and welding of large steel plates. Most of them are due to errors in raw material processing, deformation or jamming during hoisting and welding. As a result, the horizontal gap between the two steel plates that need to be spliced ​​is too large. At this time, hoisting or manual prying is required to narrow the gap. After that, multi-layer and multi-pass surfacing welding is usually used to realize the connection of the two steel plates. Most of the large gates are large in mass and volume, and it is not easy to operate when hoisting to narrow the gap. It is difficult to pry...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a special tool for closing the gaps of steel structural steel plates, so as to solve the problem of using hoisting or manual prying to narrow the gaps in the above background technology, which is time-consuming, laborious, and unsafe, because the gate steel plates are of high quality. , large volume, usually with little effect or unsatisfactory results after the gap is closed, if the gap is too large when welding, the weld seam formed will be too wide, so that the mechanical properties of the welded joint of the two steel plates will be reduced and the stress will increase, etc. , which will eventually greatly reduce the life of the weld, and requires a certain degree of precision when welding the gap
