Abstract

PURPOSE:To reduce the complication of management resulting from increase in the kinds of clamps and expenses required for the management by clamping three kinds of different diameter pipes with one clamp. CONSTITUTION:An embracedly attached piece 4 is pivotally mounted on a pivot pin between an embracedly held body 1 and an embracedly attached body 2, and in the case of clamping a small diameter pipe, the embracedly attached pirce is put upon the pipe, and in the case of clamping a medium or a large diameter pipe, the embracedly attached piece is set in the embracedly held body, which is covered with an auxiliary embracedly held body 3. The spherical receiving part A2 of the embracedly attached body is pressed with a bolt 7 according to the diameter of the pipe for clamping the pipe.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp used for connecting steel pipes such as temporary scaffolds and shelves.

[0002]

2. Description of the Related Art Conventionally, one kind of clamp corresponds to one kind of diameter. However, since several types of round and square pipes are used for the pipes that are normally used, it was necessary to prepare a clamp corresponding to each pipe.

[0003]

The pipes are orthogonal, parallel,
In the case of diagonally assembling, according to the conventional technique, a clamp suitable for each pipe had to be used by tacking at the back of the clamp or opening a window and crimping. Therefore, it is necessary to prepare a dedicated combination for several types of round and square pipes for each of the orthogonal case, the parallel case, and the oblique case, which is an enormous number of combinations. Managing this many types of clamps is cumbersome and expensive. The present invention has been devised to solve this problem.

[0004]

[Means for Solving the Problems] For example, one clamp is devised so that two kinds of square pipes and one kind of round pipe can be clamped and another one clamp can clamp three kinds of round pipes having different diameters. Is.

The structure of the clamp of the present invention is such that one end of the hugging body 1 and the hugging body 2 are pivotally mounted, and the hugging body 2 and the hugging piece 4 are pivotally mounted inside the hugging body 1. There is. Both ends of an inverted concave auxiliary holding body 3 are pivotally attached to the other end of the holding body 1, and a bolt 7 is screwed onto the tip of the auxiliary holding body 3. The tip spherical portion of the bolt 7 presses the spherical receiving portion A2 on the outer surface of the other end of the holding piece 2 in the case of a thick pipe, and the other spherical receiving recess A1 of the holding piece 2 in the case of a thin pipe. In this case, the hug piece 4
Remains inside the hugging body 1. Thus, the holding body 1, the holding body 2, and the auxiliary holding body 3 uniformly press-hold the pipe. However, in the case of holding the thinnest pipe, the holding piece 4 is pulled out from the holding body 1, placed on the pipe held in the holding body 1, and the holding body 2 is brought into contact with the holding piece 4 from above. , The auxiliary holding body 3 is covered and crimped with the bolts 7 to hold the pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view showing a Φ42.7 pipe clamped. The holding piece 4 pivotally attached to the holding body 1 is pulled out from the holding body 1 and placed on the pipe of Φ42.7 held.
The hugging body 2 is covered on the hugging piece 4, and the auxiliary hugging body 3 is further stacked on the hugging body 2 and pressure-held with bolts 7.

FIG. 2 is a view in which a Φ48.6 pipe is clamped. The hugging piece 4 is housed in the hugging body 1, and the Φ48.6 pipe hugged by the hugging body 1 abuts the hugging body 2 from above and further covers the auxiliary hugging body 2. Then, the spherical surface receiving recess A1 is crimped with a bolt to hold the pipe.

FIG. 3 is a view showing a Φ60.5 pipe clamped. Similarly to the above, the holding piece 4 is housed in the holding body 1, and the pipe of Φ60.5 held by the holding body 1 contacts the holding body 2 from above, and further the auxiliary holding body 2 And the spherical receiving recess A2 is crimped with a bolt to hold the pipe.

FIGS. 4, 5 and 6 show an example of a clamp which can be used both as a round pipe and a square pipe, and FIG. 4 shows a case where a φ48.6 pipe is clamped. The holding piece 4 pivotally attached to the holding body 1 is pulled out from the holding body 1 and placed on the pipe of Φ48.6 held. The hugging body 2 is covered on the hugging piece 4, and the auxiliary hugging body 3 is further stacked on the hugging body 2 and pressure-held with bolts 7.

FIG. 5 shows a view in which a 50-square pipe is clamped by the clamp. The hugging piece 4 is housed in the hugging body 1, the hugging body 2 is brought into contact with the 50-square pipe held by the hugging body 1, and the auxiliary hugging body 3 is further covered. The spherical receiving recess A1 is crimped with the bolt 7 to hold the pipe.

FIG. 6 shows a view in which a 60-square pipe is clamped by the clamp. The hugging piece 4 is housed in the hugging body 1 as described above, and the hugging body 2 is brought into contact with the 60-square pipe held by the hugging body 1 and the auxiliary hugging body 3 is further covered. Then, the spherical surface receiving recess A1 is crimped with the bolt 7 to hold the pipe.

It should be noted that FIGS. 4, 5 and 6 are views in which two clamps are caulked so that the pipe can be clamped at right angles.
It is possible to orthogonally cross two types of square pipes with different diameters and a round pipe.

[0013]

As described above, one type of clamp can clamp three types of round pipes, and another type of clamp can clamp square pipes and round pipes. Therefore, the number of types of clamps with large and small diameters, round pipes and square pipes,
Also, because of the combination, the complexity is reduced and the cost is saved.
