Accurate positioning method for stiffening plate of H-shaped steel component

Abstract

The invention discloses a precise positioning method for a stiffening plate of an H-shaped steel component. The precise positioning method comprises the following steps: 1) measuring, marking and carrying out region division; 2) installing a guide slide rail; (3) a movable limiting mechanism is installed, adjusted and positioned; 4) mounting an auxiliary fixing device; and (5) the connecting plates and the H-shaped steel beams are welded and fixed in sequence. The device is simple and reasonable in structural design, high in practicability, clear in principle and simple and convenient to adjust and operate, the H-shaped steel beam is segmented and divided in the length direction according to the length of the guide sliding rail and the actual length of the H-shaped steel beam, and step-by-step welding and positioning of the connecting plate are conducted with the divided segments as units; according to the auxiliary device for welding and fixing the connecting plates, the connecting plates at one division section are welded and installed firstly, after all the connecting plates in the division section are welded and installed, the whole auxiliary device is moved to the next division section, welding and positioning of the connecting plates at other division sections are conducted till welding and fixing of all the connecting plates are completed, the whole installation process is reasonable and scientific, and actual operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of welding and positioning of H-shaped steel connecting plates, and in particular relates to a precise positioning method for stiffening plates of H-shaped steel components. Background technique [0002] The scope of application of steel structures in national economic construction is becoming wider and wider. It can be said that it covers various industries. Lifting steel structure construction engineering is an ancient and brand-new industry that is booming in my country's construction industry. It is a green and environmentally friendly product that promotes traditional An important vanguard in the development of the construction industry to high-tech. As the most important part of the steel structure, H-shaped steel is often an important part of the foundation support columns and beams. Since the steel structure building nodes are all welded and connected through the connecting plates, the steel structure...

Problems solved by technology

As the most important part of the steel structure, H-shaped steel is often an important part of the foundation support columns and beams. Since the steel structure building nodes are all welded and connected through the connecting plates, the steel structure building needs There are many connecting plates, and there are often disadvantageous phenomena such as positioning deviation and long time consumption during manual positioning and installation
