Abstract

PURPOSE:To provide a highly practical pipe fastener for concrete form construction ensuring extremely high working efficiency, while allowing the fastener to be threaded to a separator simply by turning an L-shaped handle plate around, and further allowing the one-touch completion of a mounting work by fixing the L-shaped handle plate in erected state and inserting a pipe therein from upper level. CONSTITUTION:A washer 4 with an internally threaded hole 3 to be screwed to the externally threaded lever 2 of a separator 1 in a fastener for a concrete form construction work, is fitted with a turning L-shaped handle plate 5 at right angles. In addition, the inner edge of the L-shaped handle plate 5 is formed to have a pipe holding edge 8 of such shape as allowing a pipe 7 for contact with a slate to be coupled and held in pressed contact with the slate 6, simply when the pipe 7 is inserted from upper level. Moreover, an internally threaded hole 3 is formed near the upper side of the washer 4 in state where the L-type handle plate 5 is held in erected state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe fixing metal fitting for a concrete metal mold construction tightening metal fitting.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional pipe fastening tool for concrete formwork has a male screw rod 2 of a separator 1 projecting outward from a weir plate 6, and a male screw rod projecting from the weir plate 6. A female screw hole 51 provided at the tip of the mounting bolt 50 is screwed to the screw rod 2 to fix the mounting bolt 50, and the pipe 7 is held by the pipe tightening metal fitting 52 attached to the mounting bolt 50, and tightened. Tighten nut 53 to tighten pipe fitting 52
Thus, the pipe 7 is pressed against the weir plate 6.

This operation of the tightening metal fitting is extremely troublesome because it requires two operations of the spanner rotation, that is, screwing the mounting bolt 50 and tightening the tightening nut 53.

Further, concrete adheres to the mounting bolts 50, making it difficult to screw the tightening nut 53, and the concrete adhered to the mounting bolts 50 must be removed before reuse, which is troublesome.

[0005]

SUMMARY OF THE INVENTION The present invention can be carried out in a single rotating operation without using a spanner, and in addition, it is convenient for concrete formwork construction in which pipes can be mounted with one touch. A pipe fixing metal fitting is provided.

[0006]

The gist of the present invention will be described with reference to the accompanying drawings.

A female screw hole 3 to be screwed onto a male screw rod 2 of a separator 1 in a fastening tool for concrete formwork construction.
The L-shaped handle plate 5 for rotation is continuously connected to the seat plate 4 provided with the right angle with respect to the seat plate 4, and the pipe 7 for bringing the inner edge of the L-shaped handle plate 5 into contact with the weir plate 6 is inserted from above. The upper portion of the seat plate 4 when the pipe holding edge 8 is formed in a shape that can be fitted into the weir plate 6 and can be held in pressure contact with the weir plate 6, and the female screw hole 3 is held in the upright state of the L-shaped handle plate 5. The present invention relates to a pipe fixing metal fitting for concrete formwork, which is characterized in that it is formed closer to it.

[0008]

When the L-shaped handle plate 5 is rotated by hand by placing the female screw hole 3 of the seat plate 4 on the male screw rod 2 of the separator 1 protruding from the weir plate 6, the seat plate 4 is rotated. It is attached to the male screw rod 2.

When the seat plate 4 is pressed against the weir plate 6, L
Hold the shaped handle plate 5 upright and insert the pipe 7 from above.
The pipe holding edge 8 is held in pressure contact with the outside of the weir plate 6 to complete the mounting work.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawing, a female screw hole 3 is provided near the upper part of a seat plate 4, and a distance (area) S for supporting a reaction force of a pipe 7 which is pressed and held.
Is increased to increase the pipe holding strength. Although the drawing shows the case where the pipe 7 is directly pressed against the weir plate 6, when the pipe 7 arranged in the horizontal direction is pressed against the weir plate 6 via the pipe arranged in the vertical direction, L The horizontal side 5a of the shaped handle plate 5 may be designed to be longer by that amount.

In the figure, reference numeral 9 is a fastening plate attached to the separator 1 that abuts the inside of the weir plate 6.

[0012]

Since the present invention is constructed as described above, the screwing operation to the separator is completed by simply turning the L-shaped handle plate by hand, and the L-shaped handle plate is stopped in the upright state, and the pipe is It is a pipe fixing metal fitting for concrete formwork construction that is extremely practical and improves installation efficiency with a single touch by simply inserting from above.

Further, since the present invention is composed of a seat plate and an L-shaped handle plate, it is extremely compact and has excellent storability, and it can be reused as it is. It becomes a pipe fixing metal fitting.

Further, according to the present invention, since the female screw hole is formed near the upper portion of the seat plate when the L-shaped handle plate is held upright, the distance (area) for supporting the reaction force of the pipe held by pressure contact.
It becomes a pipe fixing metal fitting for concrete formwork with large S and high pipe holding strength.
