DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head fitting structure to be attached to a pipe, and more particularly to a head attached to a pipe to be used at the tip of the pipe when assembling a scaffold using the pipe or providing an enclosure. Metal fitting structure.

[0002]

2. Description of the Related Art Generally, when assembling a scaffold or providing an enclosure using a pipe at a building construction site or the like, in order to obtain stability in the assembled scaffold or enclosure, the above pipe is generally used. The tip is buried in the ground.

[0003]

However, in such a case, it is very difficult to insert the tip of the pipe into the soil at once. Therefore, when burying the tip of the pipe in the soil, the same operation of inserting the tip of the pipe into the soil is repeated several times, and a hole is dug down in the soil by the pipe, and the hole is fixed. When the depth of the pipe is reached, the tip of the pipe is placed in the above hole, the soil is buried and covered, so this work is very troublesome, and at the same time, time and labor There was a problem of spending.

The present invention solves the above problems, and particularly when assembling a scaffold using a pipe or providing an enclosure at a construction site or the like, the tip of the pipe can be easily placed in the soil in a short time. It is an object of the present invention to propose a head fitting structure to be attached to a pipe which can be buried to form a building such as a scaffold or an enclosure.

[0005]

Means for Solving the Problems As means for solving the above-mentioned problems, a head metal fitting structure to be attached to a pipe according to the present invention is used when assembling a scaffold or providing an enclosure at a construction site or the like. And a head fitting having a conical or polygonal pyramid shape, and having a proximal end slidably and modestly with the inner surface when attached to the pipe. A mating engagement piece is vertically provided, a tongue piece is attached to the engagement piece so as to be orthogonal to the engagement piece, and the tongue piece has elasticity,
Further, it is characterized in that it is formed slightly longer than the inner diameter of the pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a head fitting attached to a tip of a metal pipe 2 used when assembling a scaffold or providing an enclosure at a construction site or the like. Has a hollow, conical shape, and has three metal engaging pieces 3 suspended from the base end thereof at equal intervals.

The head fitting 1 is not limited to a conical shape, but may have a polygonal pyramid shape such as a hexagonal pyramid or an octagonal pyramid. Further, the number of the engagement pieces 3 is not limited to three, but may be more or less. Furthermore, the head fitting 1 and the engagement piece 3 are not limited to metal, but may be reinforced plastics.

Next, each engaging piece 3 has a slightly curved shape so that both sides in the longitudinal direction are located inside, and the tip is bent inward. When the head fitting 1 is attached to the tip of the pipe 2, each of the engaging pieces 3 has a surface 3 a.
Is formed so as to engage with the inner surface 2a of the pipe 2 while rubbing with moderateness.

A metal tongue 4 is provided at a position slightly above the inner center of one engagement piece 3 so as to be orthogonal to the engagement piece 3, and the tongue 4 has one side 4 a. It is bent in an L shape and is fixed to the back surface of one of the engagement pieces 3 via screws 5. Further, the other side 4b is formed so as to be bent downward at the center, and the tip of the other side 4b is formed to be curved so as to substantially conform to the inner surface 2a of the pipe 2. The tongue piece 4 is formed slightly longer than the inner diameter of the pipe 2 and has elasticity.

The tongue piece 4 is not limited to metal, but may be made of, for example, reinforced plastics. Further, the engagement piece 3 may be formed integrally with the engagement piece 3.

The head fitting 1 attached to the pipe 2 is constructed as described above.
By fitting the head fitting 1 to the tip of the pipe 2 as shown in FIG. 2A, the head fitting 1 can be attached to the tip of the pipe 2 as shown in FIG. In this case, since the tongue piece 4 is formed slightly longer than the inner diameter of the pipe 2,
2a, the tip of which abuts against the inner surface of FIG.
Is located below. And since the tongue piece 4 has a force in the return direction due to elasticity, the state where the tip is always in contact with the inner surface of the pipe 2 is maintained, and at the same time, the tip is slightly longer than the inner diameter of the pipe 2. Due to the formation, the head fitting 1 attached to the tip of the pipe 2 can be prevented from falling off by being caught when trying to withdraw.

When the head fitting 1 is detached from the pipe 2, the purpose can be easily achieved by pulling while turning the head fitting 1.

By using the pipe 2 having the head fitting 1 attached to the tip as described above, the pipe 2 can be easily erected in the soil 6 and, as a result, the construction as shown in FIG. At a site or the like, the enclosure 8 can be provided by supporting the net member 7 with the pipe 2.

According to the structure of the head fitting to be attached to the pipe as described above, the head fitting 1 can be easily attached to the pipe 2 by fitting the head fitting 1 to the tip of the pipe 2. . The head fitting 1 attached to the pipe 2 has a tongue piece 4 provided on one of the engaging pieces 3 vertically provided at the base end of the head fitting 1, and a force in a return direction is exerted by elasticity. Since the state where the tip of 4 is always in contact with the inner surface of the pipe 2 is maintained, the state of the head fitting 1 attached to the pipe 2 can be maintained.

Further, since the tongue piece 4 is formed slightly longer than the inner diameter of the pipe 2, the tip of the tongue piece 4 is strong against the inner diameter of the pipe 2 when the head fitting 1 is pulled out. To be caught and serve as a stopper,
It is possible to prevent the head fitting 1 from slipping out of the pipe 2 unnecessarily.

Furthermore, since the head fitting 1 attached to the tip of the pipe 2 has a conical shape, the pipe 2 can be easily pushed into the soil 6, whereby
The enclosure 8 can be provided within a short time by supporting the net member 7 on the pipe 2 by appropriate means.

[0018]

As described above, according to the head metal fitting structure for mounting to a pipe according to the present invention, the head metal fitting can be easily attached to the pipe by fitting the head metal fitting to the tip of the pipe. it can.

In the head fitting attached to the pipe, since a tongue provided on one of the engaging pieces vertically provided at the base end of the fitting has elasticity, a force in the return direction is exerted by the elasticity. The state in which the tip is always in contact with the inner surface of the pipe is maintained, and the state of the head fitting attached to the pipe can be maintained.

Further, since the tongue piece is formed slightly longer than the inner diameter of the pipe, the tip of the tongue piece strongly contacts the inner diameter of the pipe when the withdrawal action is applied to the head fitting, so that the friction coefficient is large. As a result, it serves as a stopper, and it is possible to prevent the head fitting from unnecessarily coming out of the pipe.

Furthermore, the head fitting attached to the tip of the pipe has a conical or polygonal pyramid shape.
Since the pipe can be easily pushed into the ground, the pipe can be used as a support for assembling a scaffold at a construction site or providing a fence, etc., to achieve its purpose within a short period of time. In addition to the stability of the building.
