Abstract

This design minimizes the buckling phenomenon because vibration is generated rather than up and down piping vibration when the earthquake occurs between the water tank of the fire fighting system and the pump connection pipe. Seismic resistant function The seismic support is installed to maintain the overall structure and valve connection <Stripping valve + strainer> initially. It is designed to be fixedly installed to prevent vibration and maintain function.
It is necessary to develop seismic design that minimizes the buckling phenomenon of piping and performance test is a priority. The above support is installed in the water piping and the gas piping so that leakage and leakage at the joint part are prevented at the time of earthquake

Description

Function retaining resilient support {omitted}

This design is characterized in that when the earthquake occurs, it separates from the <open-close valve + strainer> between the tank of the fire-fighting equipment and the pump connection pipe.

1. Made of stainless steel and hot dip galvanized

2. The welded joint of 2.3.4.5 in figure 4 is treated by a welding method which is more safe than the screw processing.

3. The 5-sheet connection in Figure 4

Base plate <left and right 1EA> + anchor bolt <left and right 4EA>

Anchor bolt fixing and penetration depth 10cm or more

Movable weight <wp> 1000kg or less Diameter 12mm or more

Movable weight <wp> 1000kg or more Diameter 20mm or more

4. Fixing device considering slenderness ratio according to piping size and piping and floor height.

In order to prevent the occurrence of bending, bending and twisting phenomena between the water tank and the pump when an impact or vibration occurs due to earthquake or the like, it is possible to distribute the center of gravity of the pipe more than the conventional pipe strut type in order to prevent this. + Strainer &quot; is a technique relating to a fastening device for a durable supporting structure to maintain a function-maintaining state

In order to solve this problem, we developed a seismic design that can minimize the buckling phenomenon of the piping by defining the initial strut support

The present invention is characterized in that the conventional horizontal support bracket is fixed to the bracket 4 of FIG. 4 and the bracket 4 of FIG. 4 in order to solve the problem that the slenderness ratio is higher than that of the support bracket. do. Performance testing is the challenge.

This design is simple in structure, durable and can be precisely fixed, and it is also possible to prevent leakage and leakage at joints in case of earthquake by installing the above support on waterworks and gas piping

The technical feature of the support is to minimize the buckling of the pipe

Open / close valve between connecting piping. Install near the strainer joint. It shall be fixed to the storage vessel of other gas system fire extinguishing facilities, the alarm system, and the control panel so as not to be conducted.

Claims (1)

It is a method to minimize vibration caused by seismic vibration between water tank and pump connection pipe of fire fighting equipment. It is possible to distribute the center of gravity of piping moving weight <wp> more than existing horizontal strut type. 4><2> FIG. 4 is a perspective view of a support structure of a functional retainer according to an embodiment of the present invention,
Slender ratio <L / r> is the ratio of the length of the strut <L> to the minimum radius of rotation <r>. As the slenderness ratio increases, the buckling phenomenon occurs, which is liable to be destroyed or damaged when the geological condition occurs.
