The conventional clamp has a structure in which one end of a pair of semi-clamps corresponding to each other in the same shape is connected by a hinge (or a hinge), and the other end is tightened by a bolt or a nut. Therefore, in order to fix the pipe with the clamp, the bolts and nuts fastened at the other end of the half clamp are loosened, the space between the two half clamps is opened, the pipe is inserted between the half clamps, and then the pipe is rewound and wrapped so as to be close to the outer circumference of the pipe. Thereafter, the other end of the half clamp is tightened with bolts and nuts again to fix the pipe.

However, since the bolts and nuts for tightening the half-clamps are separated from the clamps, the bolts and nuts that are held each time the half-clamps are clamped, There is an inconvenience in that it is necessary to take out the fastening work.

In addition, there are many cases where the bolts and nuts that are held are dropped or shed in the process of taking out the bolts and nuts, thereby delaying the working time and also pointing out the problem of the cost increase due to the loss of bolts and nuts.

The binding member 400 may include a fastener holder 410, a bolt bolt 420, and a fastening nut 430 as a substantial part of the present invention.

As described above, the conventional binding member is formed separately from the clamp, so it is troublesome to carry it separately. However, in the binding member 400 of the present invention, the bolt bolt 420 corresponding to the existing bolt is inserted into the first Since the bolt and nut are assembled so as to be rotatable to the half clamp 200, it is not necessary for the field worker to carry the bolt and the nut separately, thereby solving the problem that the bolt or nut is lost or dropped during the tightening operation.

The fastener holder 410, which is one element of the binding member 400, is formed integrally with one of the first and second half clamps 200 and 300. For example, if the fastener holder 410 is coupled to the first half clamp 200, 1 fastening piece 221, as shown in Fig. Of course, it is natural that it can be installed adjacent to the second fastening piece 321 if it is combined with the second half clamp 300. [

The bolt bolt 420 which is another component of the binding member 400 includes a cylindrical head portion 421 and a screw rod 422 integrally provided on the surface of the head portion and fastened with a tightening nut 430 Lt; / RTI >

The fastener holder has a holder body 411 having a ground surface 411a on which a part of the surface of the head portion 421 of the bolt bolt 420 is grounded.

For example, the elastic piece 412 may be formed in a plate shape whose upper end is connected to the upper end of the holder body 411, and is sloped so as to approach the first fastening piece 221 as it goes downward. Therefore, when the head part 221a is retracted, the resilient piece 412 is pressed by the holder body 411, and when the pull-in is completed, the pressing force against the resilient piece 412 is removed, , That is, in the form of a gradient. At this time, since the lower end of the restored elastic piece 412 blocks the upper part of the head part 221a, the arbitrary detachment of the bolt bolt 420 can be prevented unless the elastic piece 412 is forcibly pressed.

The elastic piece 412 may be disposed on both sides of the upper portion of the holder body 411 and between the elastic pieces 412 may be formed before or after the insertion into the fastening groove 221a of the first fastening piece 221 A mounting groove 413 for mounting the swivel rod 422 may be provided.

In this case, in the process of fitting the head part 221a between the holder body 411 and the first fastening piece 221, the fastener holder 410 can be manufactured by injection molding. The first fastening piece 221 may be deformed in a direction away from the first fastening piece 221 while receiving a load. In this case, since the fastener holder 410 and the first fastening piece 221 are separated from each other, the head part 221a can not be separated. In order to prevent this, it is preferable that a support block 700 for supporting the rear surface of the fastener holder 410 is provided on the first half clamp 200.

Although the ratchet bolt 420 is fitted to the upper portion of the fastener holder 410, the first fastener piece 221 and the second fastener piece 321 in the above embodiment, The clamping grooves 221a and 321a of the elastic piece 412 and the first and second clamping pieces 221 and 321 provided on the holder body 411 of the first clamping member 410 are inserted in front of the clamp 100 And the ratchet bolts 420 are inserted into the elastic pieces 412 and the engagement grooves 221a and 321a facing forward.

This is an embodiment in which the fitting direction of the bolt bolt 420 is changed in consideration of the work convenience of the operator.
