Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] Such as Figure 1-5 shown.

[0042] A straight hook-shaped corner pile, which is composed of a straight hook side C, a horizontal side D, a circular arc segment B and an oblique hook side A, the straight hook side C and the horizontal side D are perpendicular to each other, and the circular arc segment B is respectively connected to the straight hook side C and oblique hook side A are connected to form a lock, the angle between oblique hook side A and straight hook side C is 200 degrees, and the thickness of the selected raw material strip steel can be selected according to 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.

[0043] The present invention adopts the method of continuous roll-type cold-bending forming to directly obtain continuous right-ang...

Abstract

The invention provides a continuous cold-roll-forming shaping method of a straight-hook-shaped corner pile. The straight-hook-shaped corner pile consists of mutually perpendicular straight hook sides (C), an arc section (B) integrally connected with two hook sides and an oblique hook side (A) connected with the arc section (B), wherein the angle between the oblique hook side (A) and the straight hook side (C) is 200 degrees, and the shaping method of the straight-hook-shaped corner pile is characterized by comprising the steps of: preparing materials, performing 16 times of continuous cold-roll-forming shaping and cutting off process. The continuous cold-roll-forming shaping method of straight-hook-shaped corner pile has the advantages of high efficiency, stable quality and random length;besides, corresponding materials can be connected according to design requirements and various raw materials are available.

Description

technical field [0001] The invention relates to a steel material for construction, in particular to a cold-bending forming method of steel sheet piles, in particular to a continuous roll-type cold-bending forming method of straight hook-shaped corner piles. 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 in the use that the existing steel sheet piles still need to use on-site welding or use welded corner piles when cornering or when different forms of steel sheet piles are spliced ​​or steel sheet piles are fixedly connected to pipe piles. Only then can the steel sheet pile be 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 ste...
