Description

Technical Field

[0001] The utility model relates to the technical field of section steel bases, in particular to an H-shaped steel base with anti-offset function. Background Technique

[0002] The H-shaped steel is an economic section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". The cross-section of the H-shaped steel usually includes two parts: the web and the flange plate, also known as the waist and the edge. The H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structure weight. Before leaving the factory, the ends of the H-shaped steel need to be cut and drilled to meet the requirements of connecting multiple H-shaped steels through bolts.

[0003] When the H-shaped steel is processed, it is placed statically on the processing base. When the H-shaped steel is processed, it will be subjected to a large external force, resulting in warping and position offset, which reduces the processing accuracy of the H-shaped steel and affects the finished product quality.

[0009] Preferably, one end of the bidirectional screw is fixedly connected with a second bearing, and the other end of the bidirectional screw is fixedly connected with a transmission gear. A chain is meshed on the surface of the transmission gear.
