Preparation process of a bending-resistant triangular steel

Abstract

The invention discloses a preparation process of a bending-resistant triangular steel. Firstly, several pairs of U-shaped frames are equidistantly arranged on one side of the main structure, and then the main structure and the U-shaped frames are welded and fixed by a welding device. After the two are welded and fixed, the raw material plate of the main structure is continuously bent through the movable mold groove device, the stopper device and the pressing device. The center support block is inserted into the preset position, and the center support block and the U-shaped frame are welded and fixed to obtain a bending-resistant triangle steel, so that the welding and bending process of the triangle steel can be completed at one time, and the gradual bending method is compared with one-time The successful bending reduces the elastic recovery ability of the steel plate, avoids the obvious recovery deformation of the main structure after the successful bending, and affects the quality of the formed main structure, so that the central support block can be accurately inserted between the two U-shaped frames and completed. Welded connection to U-shaped frame.

[0002] With the rapid development and construction of cities, land resources are gradually in short supply, and the types and heights of urban buildings are gradually increasing. In order to ensure that the strength of buildings can meet the requirements, various emerging building materials have also been developed rapidly. Among them, triangular steel is A steel material with a triangular cross-section. According to the location of the triangle steel and the strength of the building, the triangle steel is mainly divided into solid triangle steel and folded L-shaped triangle steel building materials. The solid triangle steel building material has high strength and is not easy to build. The characteristics of bending, but it uses more materials, high cost and heavy weight, and can only be used in some places. Compared with solid triangle steel building materials, the folded hollow triangle steel is lighter in weight and lower in cost, but Compared with the former, its strength is also significantly lower, and it is prone to deformation during use, which affects the normal use of triangular steel. Therefore, the mixed use of the two methods is often used in modern buildings, which will lead to the use of a large number of solid triangular steel in some buildings. Steel increases the construction cost and the building load. In addition, in the prior art, the solid triangular steel material is mainly prepared by casting, while the hollow triangular steel is prepared by bending rectangular steel plates. Among them, The processing equipment in the prior art intelligently plays a simple bending effect, and the bent triangle steel is prone to recovery deformation, which affects the final shape of the triangle steel. In order to solve the above problems, the present invention provides the following solutions
