Special Electric Wrench For Steel Structure Installation

Steel structure is composed of steel materials, is one of the main building structure types. Structure is mainly made of steel and steel beam steel, steel column, steel truss and other components, and the use of silane, pure manganese phosphating, washing drying, galvanized rust and rust prevention process. Members or components are usually connected with welds, bolts, or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields. Steel structure is easy to rust, general steel structure to rust, galvanizing or coating, and regular maintenance.

High-strength bolt connections are commonly used in steel structure engineering. High-strength bolt connections also consist of bolt rods, nuts and washers. High-strength bolt connection Tighten the high-strength bolt with a special wrench and apply the specified pre-tension to it. The high strength bolt connection mainly consists of large hexagon type high strength bolt connection and torsional shear type high strength bolt connection.

Fastening large hexagon high strength bolt connections with electric torque wrench:

The nuts of large hexagon type high strength bolts are hexagonal, which is required for easy use of wrench. Use an electric torque wrench to tighten the large hexagon high-strength bolt. Set the torque value in advance before fastening the large hexagon high-strength bolt. When the wrench reaches the set torque value, the wrench automatically stops.

Torsional shear type high strength bolt connection is tightened with electric torsional shear wrench:

The torsional shear bolt is constructed with a torsional shear wrench. The root of the bolt uses a reverse torsion bar to clamp the screw itself directly through the "plum blossom head", so the phenomenon of turning will not occur when the screw is screwed. The electric torsional shear wrench will keep the cut plum blossom head inside the sleeve after the fastening is completed, and then pull the trigger to pop the plum blossom head.

Shandong Machinery Industry Co., LTD., is a set of research and development, production, sales in one of the professional power tools manufacturers, the main products: Electric shear wrench, electric torque wrench detector, portable bolt torque, axial force torque, axial force, etc., after 20 years of innovation and development, the company now has 62 acres of industrial park development workshop and 3 square meters production, the introduction of a large number of high-end processing equipment made in Switzerland, Germany, Japan, become large domestic production base of electric wrench.
