Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] Such as Figure 1-5 shown.

[0039] An S-shaped corner pile, which is composed of a straight side C, an arc segment B integrally connected with both sides of the straight side C, and an oblique hook side A connected with the arc segment B, an arc segment B and an oblique hook side A constitutes a lock on one side, and the two locks are respectively located on the upper and lower surfaces of the straight side C. From any cross-section, the lock and the straight side form an approximate S-shaped structure. The steel used for cold bending The thickness of the belt can be selected according to the needs, generally 5-16 mm, such as figure 1 As shown, the angle α between the oblique hook side A and the straight hook side C is 200 degrees.

[0040] The present invention adopts the method of continuous roll-type cold-bending forming to directly obtain...

Abstract

The invention relates to a continuous roll type cold-bending forming method for an S-shaped corner pile. The S-shaped corner pile comprises a straight edge (C), circular arc sections (B) and inclined hook edg (A), wherein the circular arc sections (B) are integrally connected with both sides of the straight edge (C) respectively; the inclined hook edges (A) are connected with the circular arc sections (B); one circular arc section (B) and one inclined hook edge (A) form a fore shaft; two fore shafts are respectively positioned on the upper surface and the lower surface of the straight edge (C); a section formed by the two fore shafts and the straight edge has an S-shaped structure; and an included angle of each inclined hook edge (A) and each straight hook edge (C) is 200 degrees. The forming method for a right-angle buckled angle pile is characterized by comprising the following steps of: preparing materials, carrying out 16 times of continuous roll type cold-bending forming, and cutting. The invention has the advantages of high efficiency, stable quality, changeable length, connection capability with corresponding materials according to the design requirement, wide choice range of raw materials, and the like.

Description

technical field [0001] The invention relates to a steel material for construction, in particular to a cold-bending forming method of a steel sheet pile, in particular to a continuous roll-type cold-bending forming method of an S-shaped corner pile. Background technique [0002] At present, steel sheet piles have been widely used in all walks of life due to their unique advantages. In order to popularize and apply, but people found that the existing steel sheet piles still need to be welded on site or welded into open corners when corners or when different forms of steel sheet piles are spliced ​​or steel sheet piles are fixedly connected to pipe piles. The pile can make the steel sheet pile fixed, connected or cornered. Among them, the method of on-site welding is not only affected by the operating space and environment, but also the operation is difficult, and the welding quality is difficult to guarantee, which affects the overall strength of the steel sheet pile; the cor...
