JPH11210936A - Pipe hanger for facility - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate field work, transportation and storage, by constituting a pipe hanger with a bolt having a through hole in the axial core and a steel wire penetrated through the through hole, penetrating at least one end of the steel wire through the through hole of the bolt body, and crushing the end so as to be hooked it in the through hole. SOLUTION: On end of a properly cut steel wire 5 is inserted into a through hole 4 on a head part 2 side of a bolt body 1, and an end part projecting from the top of a screw part is crushed by hitting it with a hammer. At this time, the crushed part is formed so as to be hooked to the through hole 4. After another bolt body 11 is similarly attached to the other end of the steel wire 5, the screw part of one bolt body 1 is screwed into an insert B buried in a concrete slab A and fixed. By screwing the screw part 13 of the other bolt 11 into a supporting band D supporting a piping C and fixing it, the piping can be hung and installed. By using conventional insert and supporting band, substantially useful pipehanger can be provided.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension fitting for suspending a pipe or the like under a concrete slab in facility construction.

[0002]

2. Description of the Related Art Conventionally, as a method of suspending a pipe or the like, as shown in FIG. 4, an insert is previously buried in a concrete slab, and the insert is cut into appropriate lengths. Generally, a method of screwing a so-called small-sized bolt) and attaching it to a support band for supporting a pipe at a lower end thereof has been generally used.

[0003]

In the above conventional method,
Hanging bolts have been used to support the insert and the support band at regular intervals, but the following problems have been encountered, especially when a lightweight pipe is suspended. 1. The suspension bolts have an excessive suspension load and are excessive. 2. It is heavy and bulky, making it difficult to transport and store.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a simple and reliable construction and easy transportation and storage, especially for the suspension of light-weight pipes. Is provided.

As means therefor, a bolt body having a polygonal head with a horizontal cross section formed at one end and having a through hole provided along the axis thereof, and a steel wire rod inserted through the through hole is provided. Insert at least one end of the bolt into the through hole of the bolt body,
It is characterized in that its end is crushed and formed so as to be engaged with the through hole.

According to the above structure, a crushed portion of an end portion of a steel wire rod having a through-hole formed in the screw portion side of the bolt body is formed, and the screw portion of the bolt body is screwed into an insert embedded in a concrete slab and fixed. In addition, another bolt body is similarly attached to the other of the steel wires, and a screw portion of the bolt body is screwed into a support band for supporting the pipe, and fixed, so that the pipe can be suspended. That is, without using the conventionally used hanging bolts,
Since inserts and support bands can be used as usual, there is no need for special work, and the use of thin, lightweight steel wire material also simplifies work, transport, The present invention solves the above-mentioned conventional problems, such as easy storage.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view showing an embodiment of the present invention. 1 is a bolt body,
A head 2 having a hexagonal horizontal cross section is formed at one end, and 3 is a screw portion formed to an appropriate length. The head 2 only needs to be formed so that a tool, for example, a wrench or the like can be hooked onto the side surface. That is, a general hexagonal bolt or square bolt may be used for the bolt body 1, but the present invention is not limited to this. Reference numeral 4 denotes a through hole formed along the axis of the bolt body 1. Reference numeral 5 denotes a steel wire, which penetrates the through hole 4 of the bolt body 1 and forms a crushed portion 6 at an appropriate position at the end.

Next, a method of using the embodiment of the present invention will be described. FIG. 3 is a view showing a use state of the present invention, in which one of the steel wires 5 cut into appropriate lengths has a through hole 4 on the head 2 side of the bolt body 1.
Then, the appropriate portion of the end protruding from the tip of the screw portion 3 is crushed by hitting it with a tool such as a hammer. At this time, the crushed portion is formed so as to be engaged with the through hole 4. After another bolt body 11 is attached to the other of the steel wires 5 in the same manner, the screw portion 3 of the one bolt body 1 is screwed into an insert B embedded in a concrete slab A and fixed. The pipe can be suspended by screwing and fixing the screw portion 13 to a support band D that supports the pipe C.

[0009]

As described above in detail, according to the equipment hanging bracket of the present invention, the conventional hanging bolts are not used, and the inserts and the supporting bands are the same as the conventional ones. Therefore, there is no need to perform any special work, and the work can be simplified by using a thin and lightweight steel wire rod. In addition, if the suspension bolts were used, the screws might have been loosened due to vibration, etc., but the use of steel wire rods eliminates the risk of loosening. Since it is possible to bend the work efficiency, it is possible to improve the work efficiency. In addition, it is easy to carry and store, and it is possible to obtain a practically useful hanging fitting such as being economically advantageous.
