Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hanging hanger for a pipe,

The present invention relates to a hanger for piping provided with a dustproof means, and more particularly, to a hanger for hung piping in a building, when vibration is transmitted to a building by an external force such as an earthquake, And a bolt loosening preventing means for preventing the band fixing bolt connecting the buffering portion and the holder portion constituting the hanger from being loosened and disassembled arbitrarily by vibration, .

Generally, the ceiling of a building is arranged to flow fluids smoothly, such as a fire-fighting facility or a water pipe, or a piping line arranged with built-in pipes is installed so that electric wires necessary for the electric equipment are not exposed to the outside.

In order to hang the piping on the ceiling as described above, a computer bolt having an upper portion embedded in the ceiling is installed at regular intervals, and a plurality of hangers are fastened and fixed to the bolts so that the piping can be installed on the ceiling.

However, when an external force or vibration such as an earthquake or a typhoon is strongly transmitted to the building, vibrations are transmitted to the hanger through the computer bolts embedded in the ceiling to break the pipeline and break it. In particular, when a high-pressure gas or a high-temperature fluid moves to a pipe, there is the biggest problem that causes a larger secondary accident.

Thus, in order to solve the above-mentioned problems, a hanger having a dustproof function has been provided. For example, Patent Registration No. 1031544 (name: pipe hanger for piping) is disclosed.

The fixing bolt is forcibly fixed to the mounting hole formed at the center of the supporting piece and the mounting piece of the semi- And the other half semicircular band is provided with a nut bundle at the center of the mounting bracket, and a nut metal having a coil spring attached thereto is mounted on the inner side of the support bracket from the lower side to the upper side, 1. A pipe hanger for piping for forming an anti-vibration pad integrally, comprising: a coil spring and a vibration- It is used to describe a hanger with anti-vibration features.

However, in the conventional pipe hanger constructed as described above, the coil spring is attached to the inside of the support bracket from the lower side to the upper side and is then coupled with the nut metal to buffer the coil spring. The upper end of the coil spring is engaged with the nut metal, but the lower end of the coil spring is not fixed to the inner bottom surface of the support bracket but simply abuts against the inner surface of the support bracket. Thus, when a large vibration is transmitted, there is a problem that the coil spring is twisted to an external force and can not be buffered.

Also, since the distance that the metal bolts installed on the ceiling and the nut metal fasteners can move upward and downward is limited, it is difficult to fit the metal bolts having different lengths at the time of filling, which makes it difficult to install the pipes horizontally.

When vibration is transmitted to the conventional pipe hanger, the fixing bolt and the nut bundle fastened to fix the support bracket and the semicircular band are loosened so that the semicircular band supporting the pipe having the upper weight is dropped by its own weight, There is a problem that can cause accidents.

The buffer 10 is formed to bend the plate and penetrate the pipe 100 in a longitudinal direction in which the pipe 100 is installed so as to serve as a body for hanging the holder 20 on the ceiling. A bolt through hole 11 is formed so that a head bolt 30 is inserted therein and the threaded portion is exposed to the outside and a lower portion of the band fixing hole 12 Is formed.

It is preferable that the shape of the shock absorber 10 constructed as described above is formed of a polygon including a quadrangle which can increase the supporting force and reduce the weight.

The holder 20 is installed in a band fixing hole 12 formed at a lower portion of the buffer 10 so that the pipe 100 can be received therein and suspended on the ceiling. And the upper ends of the first and second bands 21 and 22 are vertically extended to form the upper portions of the first and second bands 21 and 22. [ The first and second fastening holes 21b and 22b are formed in the first and second band upper portions 21a and 22a so that the band fastening holes 12 As shown in Fig.

As shown in FIGS. 8 and 9, the bolt loosening preventing means 80 according to the second embodiment is composed of a fixing member 81 formed to be soft so as to increase the adhesion, And a flange 83 formed on both sides of the cylindrical portion 82 and having an outer diameter larger than the cylindrical portion 82. The flange 83 is disposed on both sides of the band fixing hole 12 A flange 83 is inserted into any one of the first and second fixing holes 21b and 22b so as to escape to the opposite fixing hole so that the flanges 83 on both sides of the first and second fixing holes 21b, 21a (22a).

After the screw part of the band fixing bolt 24 passes through the hollow interior of the fixing member 81 installed as described above, the band fixing nut 25 is fastened to the head of the band fixing bolt 24 and the band fixing nut 25 compress the both flanges 83 of the fixing member 81 and are firmly fixed.

The fixing member 80 is installed in a gap between the inner peripheral edge of the first and second fixing holes 21b and 22b and the outer periphery of the threaded portion of the band fixing bolt 24 so that the band fixing nut 25 is soft And the head of the band fixing bolt 24 is strongly compressed in a state of being in tight contact with the flange 83 to prevent loosening.

Next, the bolt loosening preventing means 90 of the third embodiment is constituted as a torsional fixing member 91 formed of a soft material, as shown in FIGS. 10 to 14, And the first and second flanges 93 and 94 having large diameters are formed at one end and the other end of the band fixing bolt 24, respectively.

The first flange 93 has a plurality of fixing protrusions 93a protruding from the inner side surface at a predetermined or constant interval and a rotary protrusion 94a protrudes from the outer surface of the second flange 94 And a guide projection 94b protrudes from the inner side surface.

The torsion fixing member 91 also penetrates through the first and second fixing holes 21b and 22b like the fixing member 81 of the second embodiment so as to penetrate the inner surfaces of the first and second flanges 93 and 94 22b of the band fixing bolt 24 and the outer periphery of the outer periphery of the threaded portion of the band fixing bolt 24 are provided to be engaged with the outer surfaces of the first and second band upper portions 21a, The cylindrical portion 92 is inserted and positioned.

A fixing hole 95 is formed in the first band upper portion 21a at a position corresponding to the fixing protrusion 93a so that the fixing protrusion 93a of the first flange 93 is fitted and then fixed without moving .

A circular protrusion guide hole 96 passing through the inner side surface of the second flange 94 so as to move the guide protrusion 94b and concentric with the second fixing hole 22b is formed, The rotation protrusion guide holes 96 are formed in a circular shape in which the sections are separated and do not meet with each other.

The inner surface of the band fixing nut 25 is formed with a rotation projection groove 97 formed to insert a rotation projection 94a formed on the outer surface of the second flange 94. It is preferable that a plurality of the rotation protrusions 97 are formed at predetermined intervals so that the rotation protrusions 94a can be inserted at any position when the band fixing nut 25 rotates for fastening.

The bolt release preventing means 90 of the third embodiment constructed as described above allows the second flange 94 to be passed through the first and second fixing holes 21b and 22b and the guide projection of the second flange 94 94b are inserted into the rotation projection guide holes 96 of the second band upper portion 22a and the fixing projections 93a of the first flange 93 are inserted into the fixing holes 95 formed in the first band upper portion 21a Insert and fix.

The threaded portion of the band fixing bolt 24 is inserted into the torsion fixing member 91 so that the inner surface of the head of the band fixing bolt 24 comes into contact with the outer surface of the first flange 93.

Thereafter, when the band fixing nut 25 is fastened, it is moved in the direction of the second flange 94, and the rotation projection 94a is inserted into the rotation projection groove 97 formed on the inner side of the band fixing nut 25, Respectively.

Further, when the rotation protrusion 94a is caught in the rotation protrusion groove 97 of the band fixing nut 25 and tries to rotate, the rotation protrusion 94a may be soft and may not be able to exert a sufficient rotational force and may be bent.

15, the hanger 1 of the present invention is characterized in that an insertion groove 98 is formed in the rotation protrusion 94a and a support 99 having a rigidity such as a wire is inserted into the insertion groove 98 So as to be supported.

The rotation protrusion 94a configured as above passes through the second fixing hole 22b and then the retainer 99 is inserted so that the second flange 94 passes through the first and second fixing holes 21b and 22b And the rotary protrusion 94a having a supporting force is guided in the direction in which the rotary projection groove 97 of the band fixing nut 25 rotates and can be smoothly rotated.

The piping hanger 1 of the present invention constructed as described above can easily mount the dustproof means 40 and can perform a quick installation work by forming the dustproof means 40 on the buffer 10, In addition, since the shock absorbing spring 41 absorbs vibration transmitted to the building, it is possible to prevent the pipe 100 from being damaged due to the impact. In addition, by applying the bolt loosening preventing means 70, 80 and 91 The band fixing bolt 24 and the band fixing nut 25 are arbitrarily rotated by vibration to prevent the holder 20 from being disassembled.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the present invention.
