Embodiment Construction

[0040] The present invention will be further described below in conjunction with the 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 the lock. The angle between oblique hook side A and straight hook side C is 200 degrees. 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] In the present invention, a continuous roll-type cold bending forming method is adopted to directly obtain a continuous right-angle buckle corner p...

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 for construction, in particular to a cold bending forming method of steel sheet piles, in particular to a continuous roll cold forming method for 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 particular, the continuous cold-formed steel sheet piles developed in recent years have been widely used in the market, making this new energy-saving and material-saving building material available. It has been promoted and applied, but people have found in use that the existing steel sheet piles still need to be welded on site or welded corner piles when cornering or splicing different forms of steel sheet piles or fixing the steel sheet piles to the pipe piles. The steel sheet pile can be fixed, connected or cornered. Among them, the use of on-site welding is not only affected by the operating space and envir...
