Japanese Utility Model Sho 60-108646

  When the temporary roof 9 having a gradient as shown in FIG. 7 (a) is assembled using the universal clamp 1 and the single pipe 10, the clamp bodies 5 and 5 of the universal clamp 1 are rotatable. As a result, there is a disadvantage that the structure becomes unstable and easily collapses.

  In addition, in order to stabilize the temporary roof 9, it is necessary to attach a reinforcing diagonal member 11 as shown in FIG. 7 (b). Since the material is used, the work is time-consuming, and the space under the temporary roof 9 is narrowed.

  Therefore, in the universal clamp 1 in the conventional example, the gradient temporary roof 9 is assembled in a stable state, the material used is reduced, and the space under the temporary roof 9 can be widened. Has a problem that must be done.

  The gist of the present invention for solving the problems of the conventional example is a clamp body having a holding portion for holding a single pipe between a fixed piece and a holding piece pivotally attached to an end of the fixed piece so as to be opened and closed. Are connected to each other via a foldable connecting portion, and the connecting portion is formed by attaching a mounting portion of a U-shaped plate member to the fixed piece with a first bolt. In addition to attaching and fastening with nuts, the connecting pieces of the respective plate materials are overlapped with each other, and the second bolts are passed through the second connecting bolts and fastened with nuts.

Moreover, it is the structure which can fasten the said 2nd volt | bolt penetrated between the said overlapping connection pieces, and can fix the bending angle of the said clamp main bodies,
A configuration in which the mounting angle of the clamp body can be fixed by tightening the first bolt that has the mounting portion of the plate attached to a fixed piece;
Is included.

According to the universal clamp according to the present invention, the bending angle between the clamp bodies and the mounting angle of the clamp bodies can be freely adjusted and fixed. It can be assembled in a stable state using a single pipe. Therefore, there is no need for a reinforcing material as used in the conventional example, the labor and time can be reduced, and the space under the temporary roof can be widened.
Furthermore, not only the temporary roof but also various excellent effects of improving the usability of the universal clamp when assembling various temporary objects by connecting single pipes.

It is a front view of the universal clamp 21 which concerns on this invention. It is a top view of the universal clamp 21 which concerns on this invention. It is a perspective view of the universal clamp 21 which concerns on this invention. It is a perspective view in the state where single pipe 24 was held in universal clamp 21 concerning the present invention. It is a front view of the spacer 41 which concerns on 2nd Example. It is a perspective view of the universal clamp 1 which concerns on a prior art example. (A) (B) It is explanatory drawing which shows schematically the temporary roof 9 assembled using the universal clamp 1. FIG.

  Next, embodiments of the present invention will be described with reference to the drawings. First, in FIGS. 1 to 4, reference numeral 21 denotes a universal clamp. The universal clamp 21 includes a holding portion 25 that holds a single pipe 24 (see FIG. 4) between a fixed piece 22 and a holding piece 23. Two clamp main bodies 26 are symmetrically connected via a connecting portion 27 that can be bent.

  The fixed piece 22 is formed in a curved shape so as to follow the outer peripheral surface of the single pipe 24, and a holding bolt 29 for holding the single pipe is rotatably provided at the tip via a hinge portion 28. ing. A nut 30 is screwed onto the holding bolt 29.

  A holding piece 23 is pivotally attached to the base end portion of the fixed piece 22 via a hinge portion 31 so as to be freely opened and closed.

  The holding piece 23 is formed in a curved shape so as to follow the outer peripheral surface of the single pipe 24, and a holding portion 32 that is notched to hold the holding bolt 29 is formed at the distal end portion (FIG. 3). And FIG. 4).

  In this way, the clamp body 26 including the fixing piece 22 and the holding piece 23 closes the holding piece 23, holds the single pipe 24 in the holding portion 25, holds the holding bolt 29 in the holding portion 32, and then nuts 30 is fastened to the holding bolt 29 to hold the single pipe 24 of the holding portion 25 in a fixed state.

  The connecting portion 27 attaches the attaching portion 34 of the plate material 33 bent in a U-shape to the fixed piece 22 with the first bolt 35 and fastens the nut 39, and also connects the connecting pieces 36, 36 of the respective plate materials 33 to each other. It overlaps and the nut 38 is fixed by penetrating the second bolt 37 across the overlapping connecting pieces 36, 36 (see FIGS. 1, 3, and 4).

  In other words, bolt holes (not shown) through which the first bolts 35 are inserted are connected to the corresponding positions of the mounting portion 34 and the fixing piece 22 of the plate material 33, and fixed to the bolt holes. A first bolt 35 is inserted from the inside of the piece 22, and a nut 39 is screwed and fixed on the plate member 33 side (see FIG. 3).

  Since the plate member 33 is attached to the fixed piece 22 with the first bolt 35 and the clamp body 26 and the connecting portion 27 are attached in this way, the attachment angle of the clamp body 26 is rotated and adjusted, and the first bolt 35 is tightened. Can be fixed.

  Further, bolt holes (not shown) penetrating the second bolts 37 are connected to the corresponding positions where the connecting pieces 36 are overlapped with each other, and the upper part of FIG. A second bolt 37 is passed from the connecting piece 36 side to the lower connecting piece 36 side, and a nut 38 is screwed and fixed on the lower side (see FIGS. 1 and 3).

  In this way, the connecting pieces 36 and 36 of the respective plate members 33 are overlapped, and the nut 38 is screwed through the second bolt 37 across the overlapping connecting pieces 36 and 36. The second bolt 37 can be tightened and fixed by adjusting the bending angle between the main bodies 26 and 26 (see FIGS. 3 and 4).

  Since the universal clamp 21 configured as described above can be fixed by freely adjusting the bending angle between the clamp bodies 26 and 26 and the mounting angle of the clamp body 26, the connection state of the single pipe 24 can be adjusted. It can be maintained firmly (see FIG. 4). Therefore, a temporary roof with a gradient as in the conventional example can be assembled in a stable state using the universal clamp 21 and the single pipe 24.

  Next, another embodiment of the universal clamp will be described. The universal clamp 41 of the second embodiment shown in FIG. 5 has a configuration in which the connecting portions 43 between the clamp bodies 42 and 42 are formed in a cam shape. Therefore, the fixing degree of the clamp body 42 can be increased. In addition, the setting of the mounting angle of the clamp body 42 is performed intermittently.

  The universal clamp 21 of the present invention can not only assemble a temporary roof with a gradient as in the conventional example in a stable state using the universal clamp 21 and the single pipe 24, but also connect the single pipe 24. When assembling various temporary objects, the usability of the universal clamp 21 is improved.
