Abstract

PURPOSE:To simply and surely fix a guard fence and connecting pipes together by using a resilient wire so as to form a rear surface engaging part laid along a leg frame of the guard fence, right and left side frame parts, pipe holding frame parts, fastening side frame parts and leg frame locking parts. CONSTITUTION:The center part of a resilient wire is used as a rear surface engaging part 1 laid along a leg frame G of a guard fence, which is formed of an L-like shape steel plate, and both side parts thereof are bent with a width broader than that of the leg frame G so as to form a U-like shape side frame parts 2, 2. Then, The intermediate parts of the side frame parts 2, 2 are used as pipe holding frame parts 3, 3 which are parallel with the parts 2, 2 and which are curved in a semicircular shape having a diameter substantially equal to the diameter of a connecting pipe P. Further, the parts 3, 3 are bent at suitable positions by an acute angle in a direction parallel with the side rod parts 2, 2 so as to obtain embracing force points 4, 4 for the pipe P. Further, fastening side frame parts 5, 5 which are extensions from the points 4, 4 by a suitable length, are formed, and then the end parts of the parts 5, 5 are bent in a shape corresponding to the leg frame G so as to form leg frame locking parts 6, 6. With this arrangement, it is possible to form a guard fence which can facilitates the attachment and removal thereof and which can be repeatedly used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is used when a plurality of security fences (A-type varicates and Netfences) used at a construction site are connected in series in a security fence row installed in series. The present invention relates to a connecting tool.

[0002]

2. Description of the Related Art Conventionally, in order to connect the security fence row with a connecting pipe, the leg frame of the security fence and the connecting pipe are bound and fixed with a wire (number line).

[0003]

In the conventional fixing method, it takes a lot of labor and time to bind the leg frame of the safety fence and the connecting pipe with the wire, and there are variations in the fixed state.
It is weak and unstable against external force, and there is a risk of touching the tip of the bundled wire and getting injured or damaging clothes,
Moreover, the removal of the wire when removing the security fence was troublesome, and the wire that was used once could not be reused, which was uneconomical.

[0004]

(6) Connecting device (A) of the security fence forming (6). (Claim 1) A back engaging part (1 ') and left and right side rod parts (2') along an leg frame (G) having the same shape as the elastic wire having the same diameter as the above.
(2 '), pipe holding rods (3') (3 '), and right and left tightening side rods (5') (5 ') are formed, and the left and right tightening side rods (5 ′) Pipe holding frame (B) having (5 ′) ends bent in an inverted shape and having pressing portions (7) and (7), and an elastic wire rod having a diameter substantially the same as that of the pipe holding frame (G) at the central portion To the appropriate length by extending both ends of the hooking part (8) into a U shape with the width of the leg frame (G), and the left and right tightening side rod parts (5 ').
Semi-circular hooks (9) and (9) that (5 ') interlock.
And a leg frame holding ring (C), which is a connector (D) for the safety fence by combining the pipe holding frame (B) and the leg frame retaining ring (C) (claim 2), and L of the safety fence. It can be used as either a shaped leg frame or a round pipe leg frame.

[0005]

[Function] The back-engagement portions (1) (1 ') and the pipe holding rods (3) (3) (of the safety fence connecting tool (A) and the respective leg frames (G) of the pipe holding frame (B) The leg frame (G) of the safety fence and the connecting pipe (P) are attached to 3 ') and 3'), and the leg frame hooking portions (6) and (6) are attached to the leg frame (G), and The leg frame retaining ring (C) is attached to the frame (G), and the fastening side rods (5 ') (5') are hooked on the hooks (9) (9) of the leg frame retaining ring (C) to secure the leg frame of the security fence. (G) and the connecting pipe (P) are fixed. At the time of withdrawal, from the leg frame (G), the leg frame hooking portions (6) and (6) of the safety fence connector (A), and the hook portions (9) and (9) of the leg frame retaining ring (C)
It is a detachable security fence connector (A) (D) in which the fastening side rods (5 ') (5') are hooked and unfastened to remove the security fence connectors (A) (D).
