TECHNICAL FIELD [0001] The present invention relates to a spring hanger for a spring,

More particularly, the present invention relates to an anti-dust spring hanger provided with a spring fall preventing frame which prevents a fall-off of a spring when a vibration occurs due to a shock of a seismic wave.

Generally, the conventional piping construction method is to cut a section steel such as "A" type, "C" type, "I" type, "H" type which is general section steel by oxygen cutting or a speed cutter After welding, it was used as pipe support.

However, in such a construction method, it is necessary to carry out the multi-step process from the existing section steel to the site by carrying out the green film coating and to the completion of the insulation work, thereby increasing the work time when the worker assembles the pipe support stand in the field There is a problem that the assemblability is deteriorated.

Therefore, there is a construction of a prefabricated piping supporting stand capable of assembling a piping supporting stand by a worker in the field.

The above-mentioned piping support stand was filed with the Korean Intellectual Property Office with the application number 20-2010-0001690 (name of the invention: piping support stand) of February 17, 2010, and claims are as follows: "Insert plate A vertical channel 13 connected to a ceiling fixing bracket 12 connected to the vertical channel 13 and extending vertically downward from the ceiling front surface of the ceiling fixing bracket 12, and a pipe clamp horizontally installed horizontally and supported by the vertical channel 13 And a channel connection bracket 16 for connecting the vertical channel 13 and the horizontal channel 15 to each other, The vertical channel 13 is further provided with a piping support device 20 constituted by a clamp fixing bracket 23 and a pipe clamp 24 supported by the clamp fixing bracket 23, 13 so as to be able to support the pipe Plumbing for Jijiga, characterized in that the lure to be. " to be.

However, the conventional pipe supporting stand described above has a problem that the vibration absorbing effect can not be smoothly achieved due to insufficient absorption of vibrations (when vibration occurs when an earthquake occurs and a structure is applied) to the insert plate inserted into the ceiling portion .

Therefore, the conventional piping support platform described above has a problem in that it can not absorb the vibration received by the ceiling portion at a time of occurrence of earthquake or vibration transmitted to the structure.

In order to solve the above problem, the present applicant has filed a patent application with the Korean Intellectual Property Office with a patent application No. 20-2015-0007022 (design name: anti-corrosion spring hanger) dated Oct. 29, 2015, An absorption means (104) detachably installed at one end of the pipe fixing means (102) for absorbing the upper and lower seismic waves of the structure to prevent shaking of the pipe, And a fastening means (105) for fastening one end of the fixing means (102) and one end of the absorbing means (104).

However, the above-described conventional spring hanger for hermetic seals has a problem in that when the shaking occurs due to a shock of a seismic wave, the spring is dropped.

As a result, there is a problem that the shock absorption effect can not be smoothly achieved because the shock of the seismic wave can not be absorbed properly.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a spring release preventing frame for preventing the spring from coming off when a vibration occurs due to a shock of a seismic wave, It has a spring hanger.

However, the object of the present invention is not limited to the above-mentioned object, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided an anti-dust spring hanger having a spring fall prevention frame,

A pipe fixing means (102) for holding the pipe;

The pipe fixing means 102 is detachably installed at one end of the pipe fixing means 102 to absorb the seismic waves of the structure to prevent the piping from shaking. The through hole 106 is provided at one side of the pipe fixing means 102, (104) having a spring fall prevention frame (300) for preventing the spring fall prevention frame

And a fastening means 105 for fastening one end of the pipe fixing means 102 and one end of the absorption means 104.

As described above, according to the present invention, the anti-vibration spring hanger having the spring fall prevention frame has the effect of smoothly absorbing the vibration absorption of the seismic wave by preventing the fall of the spring when the vibration is caused by the shock of the seismic waves have.

Therefore, the present invention has an effect of preventing breakage of the piping.
