2. Description of the Related Art Conventionally, when transferring various building members such as outer wall panels, they are hung and transferred. As a method, the panels and the like are sandwiched and fixed from above and below using the weight of the transferred object. A clamping clamp was used. In this case, the transferred object does not collide with obstacles such as the skeleton and scaffolding, and when it can be transferred to the target position, the transferred object can be safely completed without problems such as falling of the transferred object. However, if a collision occurs during transfer work, or if a gust of wind blows during transfer of something with a large area such as an outer wall panel, the transferred material may float up momentarily, and the clamping force will increase at that moment. They may be lost and in some cases the transfer may fall out of the clamp. If such a falling accident of a building member occurs at a high place such as a construction site, it is highly likely to lead to a large accident.

The insertion cylinder (6) is inserted into the through hole (9) formed in the building member (8), the raising and lowering arm (2) is operated, and the compression tension member (C) is pulled by the cam action. The elastic tubular body (3) expanded by compressing and inflating the elastic tubular body (3) and the collar portion (6a) sandwich the building member (8) from both sides (or inside the through hole (9)). Then, the elastic cylinder (3) is expanded and fixed. Around this time , the free arm (15) is also actuated in the same manner, and the compression pulling member (C) is pulled by the cam action of the free arm (15) to compress and inflate the elastic cylindrical body (3). To fix the building member (8). Each of the tilting arm (2) and the free arm (15)
After activating each of them , they are lifted and transferred to a predetermined position. Since the building member (8) is fixedly transferred from both sides (or the inside of the through hole (9)) by the cam action in this way, the building member (8) does not fall off during the transfer. Very safe. Moreover, also because it idea to fix the building member (8) at the free arm (15), and reliably by the action of camming than when lifting only the cam action of the raised or lowered arm (2) lifting Even if the building member (8) collides with a scaffold or the like during transportation, the raising / lowering arm (2) falls down and the free arm (15) even if the cam (2a) separates from the flange (6a). Since the cam action of (8) is working, the building member (8) can be escaped from falling off, which is further safe. Further, when the elastic cylinder (3) is transferred to a predetermined position, the elastic cylinder (3) returns to its original state by simply returning the free arm (15) and the raising and lowering arm (2) to the original state, and the elastic cylinder (3) can be easily removed. Therefore, removal of the building member (8) is very easy and convenient.

The compression tension member (C) is mainly composed of a pivot head (1) and a tension leg (1a) integrally protruding from the lower end of the pivot head (1). And the insertion-side end portion of the tension leg (1a) stepped screw portion (6 b) is formed. A pivot hole is formed in the pivot head (1), and a pivot shaft (2c) is inserted therethrough. The pulling leg portion (1a) has a smaller diameter than the pivotally attached head portion (1) and is inserted through the insertion cylinder portion (6) and the elastic cylinder body (3), and the protruding portion from the elastic cylinder body (3). A simple ring-shaped compression brim (4) is inserted in this, and a nut (5) is screwed to the stepped screw part (6b) further protruding from this compression brim (4). The nut (5) is fixed by a retaining member (5a) such as a pin. Thus, the elastic cylinder (3) is structured so as to be sandwiched between the compression flange (4) and the insertion cylinder (6). Although the compression brim (4) is a separate body in the present embodiment, it is also possible to have an integral structure as in the modified example.

The raising / lowering arm (2) is mainly composed of an arm plate (2f) disposed on both sides of the pivot head and a suspension shaft (2d) attached to a free end. The pivoting end of the raising / lowering arm (2) is connected to the pivoting head (1) by a pivot (2).
The cam (2a) is provided on the contact surface at the pivot end so that it can be tilted up and down via c). In FIG. 1, the lower surface of the pivot end is a cam (2a), and the cam (2a) is operated when the raising and lowering arm (2) is stood up.
(2b) is a non-cam portion, and when this portion faces the collar portion (6a), it is separated from the collar portion (6a) so that the cam action does not work. The position of the cam (2a) is not limited to this, of course, and it can be freely selected from one side surface or both side surfaces or lower surface and one side surface as shown in FIGS. Further, although the cam (2a) is constructed integrally with the raising and lowering arm (2), only the cam ( 2a ) may be a separate body and may be replaced at any position with a fastener such as a bolt. . (2e) is a nut for fixing the pivot shaft (2c), and is fixed by a retaining member (2g) such as a split pin.

Therefore, as shown in FIG. 1, the insertion tube portion (6) is placed in the through hole (9) formed in the building member (8) with the cam (2a) separated from the collar portion (6a). insert. In the illustrated embodiment, the length of the insertion tubular portion (6) is selected so that the elastic tubular body (3) appears on the opposite side of the building member (8). After that, when the raising and lowering arm (2) is raised, the cam (2a) at the pivot end is
Inserts the compression tension member (C) into contact with the collar portion (6a)
Pull up to the side . Then, the compression brim (4) attached to the end of the pulling leg portion (1a) of the compression pulling member (C) presses the elastic tubular body (3) toward the insertion tubular portion (6) to compress and expand it. The outer diameter of the expanded elastic cylinder (3) is much larger than the inner diameter of the through hole (9) of the building member (8), and the collar (6)
The building member (8) is fixed from both sides by the a) and the expanded elastic tubular body (3). At this time, the flange portion (6a) comes into contact with the building member (8) with respect to the surface, and the elastic tubular body (3) comes into contact with the opposite surface with its elastic surface, so that the building member (8) is, for example, AL.
Through hole (9) even if the material is easily chipped like C material
There is no such thing as saying that the surroundings are missing. Also this
Back and forth, the free arm (15) is raised, the cam (15a) of the free arm (15) is pressed against the flange (6a), and the compression tension member (C) is pulled up to the insertion base side , and the elastic tubular body (3). ) Is compressed and expanded to fix the building member (8).

After that, the wire rope (7) is pulled and suspended as shown in FIG. 2 and transferred to a predetermined place. The clamp (A) of the present invention needs only one place if the building member (8) is lightweight, but a plurality of heavy members will be used. In addition, as described above, the insertion tube portion (6) of the clamp (A) is inserted into the through hole (9) of the building member (8), and the elastic tube body (3) is inflated and clamped from both sides. It is very safe because (8) does not fall off during transfer. Moreover, even if the building member (8) collides with the body or scaffolding during the transfer of the building member (8) and the tilting arm (2) tilts, the elastic cylinder unless the cam (2a) separates from the collar portion (6a). The compression of the body (3) is not released and the building member (8) does not fall off. Moreover, since the free arm (15) is provided independently of the raising and lowering arm (2), even if the cam (2a) of the raising and lowering arm (2) separates from the flange (6a), the free arm (15) is removed. ) Cam (15a) is a collar (6
This means that the cam action does not occur without detaching from a), the compression of the elastic tubular body (3) is not released, and the building member (8) does not fall off. When the wire rope (7) is transferred to the predetermined position, the wire rope (7) is loosened, and the tilting arm (2) and the free arm (1) are released.
5) is returned to its original state, the compression / tension member (C) is pulled back by the elastic force of the elastic tubular body (3), the elastic tubular body (3) returns to its original shape, and is easily pulled out. Therefore, removal of the building member (8) is very easy and convenient.
