[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is an exploded front view of the bellows support of the present invention. The support of the present invention comprises a single pipe 1, a tubular joint metal piece 2, a vertical brace 3, and a horizontal brace 4.

Of the above-mentioned constituent members, the single pipe 1 is, for example, 5
Four pieces with a length of about 000 mm are prepared. The joint hardware 2 has a length of 8 as an example, as shown in FIGS.
A bracket 5 for attaching the vertical brace 3 is integrally provided at a right angle on the peripheral surface of a cylindrical main body 2a having an inner diameter (for example, about 50 mm) in which the single pipe 1 can be inserted in a range of 0 mm to 100 mm. A brat 6 for a horizontal brace is integrally projected so as to be located between the brackets 5 and 5 for both vertical braces.

A large number of steps, for example, 10 at the four corners of the square.
Arrange the joint hardware 2 on the steps. In this case, the orientation of the arrangement of the joint hardware 2 is determined so that the bracket 6 for the horizontal brace is positioned diagonally inside the rectangle, and the two vertical braces 3 are arranged between the joint hardware 2 positioned vertically and diagonally. The vertical brace 3
Both ends of the are pivotally attached to the bracket 5 by the pins 7. In this case, the pin 7 is at the intersection of the two vertical braces 3.
It is rotatably connected with.

In this way, the vertical braces 3 are foldably connected to all the joint hardware 2 in the four-sided direction of the rectangle, and the bellows body is expandable and contractable so that the space between the joint hardware 2 in the upper and lower positions can be adjusted. Assemble 8. This bellows body 8
The length of one side of the square is, for example, 500m in the contracted state.
The length of the vertical brace 3 is set to be about m.

As shown in FIG. 5, the horizontal brace 4 has two braces as one set, the centers of the braces are crossed with each other, and the crossed portions are rotatably connected by a pin 7. In this embodiment, 10 sets corresponding to 10 stages are prepared. The length of the horizontal brace 4 can be set as appropriate, and this length is the width between the joint metal fittings 2 in the horizontal rectangular position in the expanded state of the bellows body 8, that is, the bellows body 8.
Is a factor that determines the length of. In this example, the length of the horizontal brace 4 was set to 500 mm.

Further, a pin 9 for preventing slippage of the single tube 1 is projected toward the inside of the main body 2a at a position facing the brat 6 for horizontal brace on the joint metal 2.
The pin 9 is formed of, for example, a bolt, and is screwed into the main body 2 so that the protruding length of the main body 2a into the main body 2a can be adjusted.

In order to assemble the support using the above-mentioned components, the bellows body 8 in the flatly folded state, the four single tubes 1 and the horizontal brace 4 in the folded state are carried into the site. Then, as shown in FIG. 6, a single pipe 1 serving as a support is inserted between the joint metal pieces 2 at the upper and lower positions of the bellows body 8, and the joint metal piece 2 is slid along the single pipe 1 to establish a vertical relationship. Widen the space between the joint hardware 2,
The bellows body 8 is extended. In this case, in the illustrated example, the bellows body 8
Extends from 1000 mm in the contracted state of FIG. 1 to 5000 mm in the extended state of FIG.

At this time, the vertical brace 3 is already pin-connected to the joint metal fitting 2 as a component of the bellows body 8. However, as the space between the joint metal fittings 2 in the vertical relationship increases, the pin-bonded intersecting portion is formed. The end connected to the joint hardware 2 spreads as the central axis.

Next, the horizontal brace 4 is expanded from a state in which it is folded in a substantially flat shape as shown in FIG. 5 around a connecting portion by a pin 7 at an intersection to a state in which two braces shown in FIG. 7 intersect at a right angle. . Then, as shown in FIG. 4, both ends of the horizontal brace 4 are fastened and fixed to the bracket 6 for the horizontal brace of the joint hardware 2 with bolts 10 or the like in this state.

In this case, since the length of the horizontal brace 4 is set to 500 mm as described above in this embodiment, the length in the diagonal direction between the joint hardware 2 arranged in a rectangle is the length of the horizontal brace 4. The length of the horizontal brace 4 determines the horizontal interval between the joint hardware 2, that is, the extension length of the bellows body 8.

When the bellows body 8 is extended as described above, the anti-slip pin 9 attached to the joint metal piece 2 is further projected toward the inside of the main body portion 2a, and the single pipe 1 is attached at the tip. The joint metal 2 is fixed by pressing so that the joint metal 2 does not slip on the single pipe 1.

Then, the jack base 11 is attached to the upper and lower ends of the single pipe 1.

[0023]

As described above, according to the bellows support of the present invention, since a single tube is inserted into the bellows body to extend it, and a horizontal brace is attached thereto, anyone can use it without any special technique. It is easily assembled and has good workability on site.
Moreover, the supporting strength can be greatly increased. Further, since it is foldable, it can be easily transported, and the extension length can be appropriately selected, so that it is possible to flexibly deal with the situation at the site.
