Abstract

PURPOSE:To fix a long-sized screw easily by forming a hole for fixation, in which a bolt with a long-sized screw is passed, to a detent section fixed to a metal material with a female screw for adjustment by welding, etc. CONSTITUTION:A hole 2b for fixing, in which a bolt 3 with a long-sized screw section 3a is passed through the position of the same axis as a female screw section 1a, is formed to a detent section 2, in which both ends of a pipe are drawn and which is joined and unified with an adjusting metal material 1 with the female screw section 1a by welding, and notches 2c are formed at both ends of the hole 2b and the hole 2b is deformed positively. The hole 2b for fixation is deformed by inserting the adjusting metal material 1 into the bolt 3 and striking the front end section 2a of the detent section 2 while the revolution of the bolt 3 is stopped by biting the hole 2b to the long-sized screw section 3a. Accordingly, the long-sized screw can be fixed easily.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention requires fixing rotation when adjusting a separator used for fixing a formwork with a long screw in, for example, a concrete structure. There is. The hardware used to fix the rotation. (Prior Art) When adjusting one side of the separator with a long screw, in order to fix the rotation, it is common to fix with a nut or welding, but both take time and effort, If it is out of reach, it is impossible. (Effect of the Invention) In the case of the present invention, the object can be easily achieved by breaking the tip of the rotation stopping portion at the position where the rotation is to be fixed. You can hit with the auxiliary rod of. (Embodiment) An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of an embodiment of the present invention, in which both ends of a pipe are drawn and welded to an adjusting hardware (1) having a female screw portion (1a) to be joined and integrated by a detent portion (2). The rotation stopper (2) has a fixing hole (2b) through which the adjusting screw passes at a position coaxial with the female screw portion (1a), and cutouts (2c) are provided at both ends thereof. Has a notch (2d) at an angle so that the pier can be prevented from slipping. FIG. 2 is an enlarged cross-sectional view of the hardware shown in FIG. 1 in which a long screw is inserted and the tip end is hit to prevent rotation. FIG. 3 is an example of its use, and the present invention is attached to an existing structure or a mountain retaining wall (4) by welding or the like for fixing a concrete placing formwork (3) in a building structure. It is a drawing in which the adjustment hardware (5) and the separator (6) having a long screw are used for adjustment, and the detent is tapped and fixed through the spar (7).

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 to FIG. 3 show an embodiment of the present invention, FIG. 1 is an overall perspective view, FIG. 2 is an enlarged vertical sectional view of an essential part, and FIG. FIG. FIG. 4 is a perspective view showing another embodiment.

Claims (1)

[Claims] A hardware (1) having an adjusting female screw (1a) for preventing rotation of a bolt (3) having a long screw portion (3a).
The tip (2) of the detent (2) fixed to the
By hitting a), the fixing hole (2b) through which the bolt passes is deformed, and it also bites into the screw part (3a) of the bolt,
A metal object characterized by stopping the rotation of bolts. The hardware according to claim 1, wherein notches (2c) are formed on both sides of the hole so that the fixing hole (2b) can be easily and surely deformed.
