Abstract

PROBLEM TO BE SOLVED: To eliminate the deformation and damage of an end part and the protrusion of a bolt tip by providing a support arm part with a fastening member having a fastening part and a journaling shaft hole, providing a receiving member with a journaling part for jounraling the fastening member, and providing a rotating member with a fastening part for fastening the fastening part of the fastening member. SOLUTION: A fixing tool is mounted on the periphery of a pipe or a bar P. A fastening member 30 jounraled on a journaling part 10b of a receiving member 10 is rotated and fastened to a fastening part 50 of a rotating member 20, and a pressing screw 40 is screwed in. Then the tip of the screw 40f comes in contact with a jaw part 51 of the fastening part 50, so that the fastening member 30 does not come off the fastening part 50. When the screw 40f is further screwed in, the fastening part 50 is pushed away toward the jounraling part 10b by the tip of the screw 40f, so that a space between a contact part 11 of the receiving member 10 and a contact part 21 of the rotating member 20 is reduced to clamp-fix the pipe or bar P firmly. Because of not being bifurcated, the fastening part 50 is strong and neither deformed nor damaged even under repeated rough handling. Also since a tip part such as a bolt with a nut is not protruded near the fastening member 30, there is no danger of a human body being injured coming in contact.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for a pipe or a rod, and is used for assembling a temporary scaffold by connecting steel pipes at a construction site, and assembling the pipe or rod vertically, horizontally or diagonally. Regarding binding equipment (generally called a steel pipe binding clamp, abbreviated as a clamp), combine pipes and rods with other products or pipes and rods as necessary, and barricades during construction work and road construction, etc. It is also used for assembly.

[0002]

2. Description of the Related Art Conventionally, there has been a steel pipe binding (commonly called a clamp) as shown in FIG. 15, and this steel pipe binding has the following structure.
No improvement was seen in its basic structure. The conventional steel pipe fastener comprises an L-shaped receiving member 1 and a fastening member 2 rotatably attached to one end of the receiving member 1. The receiving member 1 and the fastening member 2 Has a contact portion 1 that matches a part of the outer circumference of a cylindrical steel pipe P (also a rectangular pipe).
a, 1a, 2a, 2a are formed respectively, and the other end portion 1b of the receiving member 1 is provided with a nut bolt 3 having one end rotatably attached. Protrusions 2b, 2b having a U-shaped cutout 2c are formed at the end, and the other end of the nut-attached bolt 3 can be pivotally fitted into the U-shaped cutout 2c. It was
Since the steel pipe binding has the above-mentioned configuration, the steel pipe binding is externally mounted on the outer periphery of the steel pipe P, and the U-shaped notch 2c formed between the projections 2b and 2b of the fastening member 2 has the nut bolt 3 By rotating the end and fitting it, and forcibly screwing in the nut 3a screwed to the nut-equipped bolt 3, the protrusions 2b and 2b at the other end of the tightening member 2 are received at the other end 1b of the receiving member 1. As the projections 2b, 2b approach the other end 1b of the receiving member 1, the abutting portions 1a, 1a of the receiving member 1 and the abutting portions 2a, 2a of the tightening member 2 move around the outer circumference of the steel pipe P. The structure is such that the steel pipe P is pressed and tightened and the steel pipe P is fixed to the steel pipe binding tool.
When removing the rod binding device from the outer periphery of the single pipe P, it suffices to loosen the nut 3c and then reverse the above process. Although not shown, there is also a steel pipe binding tool in which the bottom portions N of the receiving members 1 of the plurality of steel pipe fastening tools having the above-mentioned configuration are fixed to each other or rotatably connected. Of course, the tube or rod of the present invention is fixed. Devices can also be connected and used in the same manner.

[0003]

Since the fixing device for a pipe or rod having the above-mentioned structure has a U-shaped notch at the other end of the tightening member, the other end is split into two as shown and described. Cage,
Therefore, the bifurcated portion is likely to be deformed or damaged, and the shape of the U-shaped cutout portion is therefore deformed, and the other end of the bolt cannot be fitted into the U-shaped cutout portion even if the other end is rotated and fitted. ,
There was a problem that it was difficult to insert it, or the inserted bolt was easily removed, or the forked part was damaged and it became impossible to insert it. Further, in the tube or rod tightening tool having the above-mentioned configuration, the other end of the bolt is rotated to fit into the U-shaped notch at the other end of the lid member, and the nut of the nut-equipped bolt is forcibly screwed in, Fixing devices for pipes or rods that are sheathed in steel pipes are tightly connected to the outer periphery of the steel pipes, but the work of screwing nuts into the bolts is very troublesome, and there are a number of accidents resulting from insufficient screwing, i.e. insufficient tightening of the nuts. There was a big danger that the shortage could cause personal injury.
Further, since the other end of the bolt is fitted into the U-shaped notch even when the other end of the bolt is rotated, the other end of the nut-attached bolt of the fixture for the pipe or rod tightly connected to the outer circumference of the steel pipe is Since it protrudes to the outer periphery of the rod fixing device, the human body often touches the other end of the protruding nut-attached bolt, causing injury, and for safety management, covers the pipe or rod fixing device with a cover. Has become commonplace. In view of the above-mentioned drawbacks, the problem to be solved by the present invention is, firstly, by eliminating the U-shaped notch at the other end of the tightening member, thereby eliminating the deformation / damage of the other end of the tightening member. Secondly, without using bolts and nuts, it is possible to eliminate insufficient tightening of nuts and various accidents due to insufficient tightening, and to attach to a pipe or rod with a hammer to fix them tightly and easily remove them. Furthermore, it is an object of the present invention to provide a fixture for a tube or rod in which the dangerous tip portion of the bolted nut does not project to the outer circumference.

When the tip of the fitting member 70 is inserted into the gap 80 and is fitted by applying pressure in the axial direction of the tube or rod P, the hooking portion 50 is pushed by the fitting member 70 as in the above-described embodiment. Since it is pushed toward the shaft supporting portion 10b, the fixing member 60 is pressed against the pipe or the rod P and fixed. As shown in the drawing, the shape of the void 80 is an inverted trapezoidal void 80, and the direction in which the fitting member 70 is press-fitted into the void 80 is a shape toward the axial center of the pipe or rod P. Is desirable. If a jaw-like projection 70a is provided on the upper end side of the fitting member 70, when the jaw-like projection 70a of the fitting member 70 is tapped from below to above when the pipe or rod P is removed, the fitting member 70 is removed. It easily comes out of the void 80. Also, the fitting member 70
If the material is made of a material having a little elasticity such as wood, hard rubber, or hard synthetic resin, the fitting member 70 press-fitted into the space 80 has a frictional resistance force against the fitting member 70 even when subjected to vibration or impact. Since it does not move against the press-fitting direction, the fitting member 70 does not loosen, and the pipe or the fixture for the pipe or the rod fixed to the rod P does not come off. Further, the fitting member 70 is made of metal, and the fitting member 7 made of metal is used.
The same effect can be obtained by coating the outer periphery of 0 with hard rubber, hard synthetic resin, or the like. Although not shown, recesses such as holes and grooves are provided on the surface of the metal fitting member 70 that contacts the hooking member 30 or the hooking portion 50, and the rubber, synthetic resin, wood When the fitting member 70 is press-fitted into the space 80 by burying or fitting the above, the hook portion 50 is pressed by the highly hard metal portion of the fitting member 70.
When the fitting member 70 functions sufficiently as the pressing member and the fitting member 70 tries to move in the direction opposite to the press fitting direction due to continuous intermittent vibration or impact, the fitting member 70 may have a recess such as a hole or a groove. It cannot be moved, that is, cannot be loosened because it is blocked by the frictional resistance force of the rubber, synthetic resin, wood, etc. embedded or fitted in. (Rubber, synthetic resin, wood, etc. have elasticity, and that elasticity is also the source of frictional resistance.) Moreover, the fitting member 70, the hooking member 30, or the hooking portion 50.
By making one of the contact surfaces with
It is also possible to make it difficult for the fitting member 70 that is press-fitted in to be loosened. Alternatively, as shown in FIG. 4, the screw 40 of the above embodiment can be used as the screw 71 as the loosening prevention member of the fitting member 70. As a matter of course, as described in the "Note" of the first embodiment, the hooking member 30 is rotatably attached to the other end of the turning member 20, and the hooking portion 50 of the receiving member 10 is fixed. It can also be provided at the other end (Fig. 5). Although not shown, a concave portion (a plurality of concave portions may be provided in a row) as a locking portion into which the tip of the screw 71 can be fitted on the side surface of the fitting member 70, that is, the side surface where the tip of the screw 71 as the loosening prevention member abuts. Desirably, a plurality of lateral grooves may be formed on the side surface of the fitting member 70 with which the tip of the threaded bolt 71 abuts). The pipe or rod fixing device having the above-described structure is mounted on the pipe or rod P,
The hooking member 30 is rotated to be hooked on the hooking portion 50, and the gap 80
When the fitting member 70 whose tip is fitted in is pressed into the fitting member 70 by tapping it from the upper side to the lower side with a hammer, the retaining portion 50 is pressed and pushed toward the shaft supporting portion 10b. It is possible to securely tightly fix a tube or rod fixing device that is pressed against the outer circumference of the. At this time, when the material of the fitting member 70 is made of a material having a little elasticity such as wood, hard rubber, hard synthetic resin, etc., the fitting member 70 has a slack preventing function, so that the fitting member 70 press-fitted into the space 80. Since it cannot move backward, the fixing device of the tube or rod will not loosen. Further, the loosening of the fitting member 70 can be prevented by providing the various loosening prevention members listed. As described above, when removing the fixing device for the tube or the rod from the tube or the rod P, the jaw or the projection 70a of the fitting member 70 can be easily detached by tapping from the bottom to the top with a hammer. A stick fixture was obtained.

[Third Embodiment] The third embodiment will be described with reference to FIGS. The main difference from the above-described embodiment is that the fitting member 70 is press-fitted into the space 80 between the latching member 30 and the hooking portion 50, and the latching member 30 and the fitting member 70 that is press-fitted are separately provided. That is, the cylindrical body 72 is externally packaged.
