Abstract

A main beam frame for factory building roof comprises a first main rod and a second main rod, the first main rod is symmetrically arranged between a first tube and a second tube, the second main rod is symmetrically arranged between a second tube and a third tube, all the circle centers of the two main rods, the first tube, the second tube and the third tube are on at the same horizontal line, a fourth tube is arranged at the middle position of the upper part of the first main rod, a fifth tube is arranged at the middle position of the upper part of the second main rod, the fourth tube is welded and connected to the first tube and the second tube which are arranged at two sides of the first main rod, the fifth tube is welded and connected to the second tube and the third tube which are arranged at two sides of the second main rod, every main rod and every tube extend in an arc-shaped manner along the working direction of the main beam frame, the welding flux and the welding technologyof the two main rods and the five tubes make welds of the main rods and the tubes uniformly and firmly connected, and the flux has good wettability and good flowability with above matrix. Nitriding treatment improves the corrosion resistance and the hardness of the surface of a copper alloy, so the service life is effectively prolonged.

Description

technical field [0001] The invention relates to a main beam frame for the roof of a factory building, belonging to the technical field of simple houses. Background technique [0002] The simple roof of the factory building has been widely used in many fields now. Due to its simple structure, light material, easy assembly and low cost, it can easily solve various temporary or short-term needs. As the main beam frame of the simple roof of the factory building, the simple roof beam frame of the factory building is the main load-bearing mechanism of the factory building. The factory building is required to be firm and stable, and can be built quickly and easily. Its structure affects its service life and safety, and the main beam frame structure and service life in the prior art are not ideal enough. Contents of the invention [0003] In order to improve the service life and safety of the main beam frame used on the top of the existing factory building, the present invention ...
