Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting fences (safety fences) provided side by side on a construction site or the like.

[0002]

2. Description of the Related Art Fences used at construction sites and the like are generally made of iron pipes, iron plates, wire mesh, and the like. Conventionally, wires, ropes, and the like are used to connect such adjacent fences. Was usually tied up.

[0003]

However, wires, ropes, and the like have a problem that if they are not tightly tied using pliers or the like, they tend to loosen easily, which requires a lot of labor and labor.

[0004]

SUMMARY OF THE INVENTION The fence connection structure of the present invention is to solve the above-mentioned problem, and the inner surfaces of both end walls of a plastic fence which are supported upright so as to be adjacent to each other. , A rib consisting of an upper narrow portion and a lower wide portion is integrally formed, and hooks are integrally formed at both ends of a flat U-shaped connecting member formed of an elastic material, and the hooks are adjacent to a fence. The hook portion is engaged with the wide portion of the rib by pushing down the connecting member after matching the small width portion of the rib.

[0005]

[Action] The hook is made to conform to the small width of the rib, and then the connecting member is pushed down to shift the hook to the wide portion of the rib. , It is possible to reliably connect.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The fences 1A and 1B shown in the figures are formed by forming a grid-like portion 3 in a square frame 2 composed of an upper frame portion 2a, a lower frame portion 2b, and both side frame portions 2c and 2d. Are formed integrally as a whole. The upper and lower portions of both side frame portions 2c and 2d are formed in a cylindrical shape, and the upper and lower ends are open. For this reason, the anchor rods 4 are inserted from the lower end, and the anchor rods 4 are buried underground so that the fences 1A and 1B can be supported upright so as to surround, for example, a construction site.

However, the intermediate portion between the side frame portions 2c and 2d is formed in the shape of several square cells, and a through-hole 5 having a wide upper half and a narrow lower half is formed inside thereof. Rib 6
Is formed. That is, the rib 6 is used for the fences 1A and 1B.
As shown in FIG. 4, the through hole 5 is formed on the inner surface of both side end walls 7 forming the both side frame portions 2c and 2d so as to protrude in a triangular shape. , A narrow portion 6a is formed above and a wide portion 6b is formed below.

Reference numeral 8 is a plastic connecting member having a flat U-shape and having hooks 9 and 9 integrally formed at both ends with the ribs 6 into which the ribs 6 can be loosely fitted. When connecting the fences 1A, 1B using the connecting member 8, the hooks 9, 9
Through the adjacent through holes 5 of the fences 1A and 1B, loosely fit the small-width portions 6a of the ribs 6 into the hooks 9 and 9, and push down the connecting member 8 as it is, the hooks 9 and 9 Is slid to engage the wide portion 6b. Both fences 1
The width of the wide portion 6b is adjusted so that the distance between the wide portions 6b of A and 1B is slightly wider than the distance between the hooks 9 and 9. When the connecting member 8 is pushed down, the width of the hooks 9 and 9 becomes wide. Part 6
Due to the reaction force received from b, the U-shape of the connecting member 8 spreads slightly outward against its elasticity, and the both end walls 7 of the fences 1A and 1B are joined without any gap. In addition,
A notch 10 is formed at the lower edge of the hooks 9, 9, and the hooks 9, 9 are formed.
When the is slid downward, the lower side of the rib 6 is loosely fitted into the notch 10 so as not to prevent the hooks 9, 9 from moving downward.

For this reason, if a plurality of connecting members 8 are fitted according to the above procedure as required in terms of strength, the fences 1A and 1B can be firmly connected with one touch. Needless to say, many more similar fences can be connected according to the width of the construction site or the like.

In order to release the connection, the connecting member 8 is pushed upward, and the hooks 9, 9 of the connecting member 8 are moved to the small width portions 6a.
, The connecting member 8 can be easily removed.

[0011]

[Effect of the Invention] As described above, the connecting structure of the fence according to the present invention allows the two fences to be easily connected with one touch simply by pushing the hook of the connecting member to the small width portion of the rib and then pushing it down. Can be. This simplifies the connection work associated with fence installation at construction sites, etc.
There is a beneficial effect that the labor is reduced.

Claims (1)

(57) [Scope of request for utility model registration] 1. A plastic fence, which is supported upright so as to be adjacent to a side wall, is integrally formed with a rib comprising an upper narrow portion and a lower wide portion on inner surfaces of both side end walls which are in contact with each other. Plane U made of material
Hooks are integrally formed at both ends of the letter-shaped connecting member, and the hooks are made to conform to the small width portions of the ribs on the adjacent fences, and then the connecting member is pushed down so that the hooks become wide portions of the ribs. A fence connection structure characterized by being engaged.
