Description

Seismic reinforcement apparatus of plumbing for construction machinery and firefighting equipment {ASEISMATIC REINFORCING DEVICE OF BUILDING MACHINE EQUIPMENT AND FIRE FIGHTING EQUIPMENT PIPE}

The present invention relates to an earthquake-resistant reinforcement apparatus, and in particular, by installing an end bracket at a connection portion of a pipe for construction machinery equipment and fire fighting equipment, seismic reinforcement of the connection portion, and using an end bracket of an adjacent connection portion with an end bracket The present invention relates to a seismic reinforcing device for pipes for construction machinery and fire fighting equipment, in which a connecting rod is fixedly installed in a longitudinal direction of a pipe and then prestressed to the connecting rod.

In general, in buildings such as large buildings or multi-composite buildings, concrete such as electric wire piping for electric wiring, refrigerant or hot water supply pipes connected to mechanical equipment for supply and drain pipes and centrally supplied air conditioning and heating, and firefighting pipes for fire suppression are used. Piping so as to be mounted on the ceiling of each floor constructed of slabs, and securely mounted as a hanger on the computer bolt embedded in the ceiling to prevent sagging and relaxation of the pipe.

On the other hand, the earthquake is becoming larger / multiple in the world, and it is highly likely to occur all the time in Korea. When an earthquake occurs, the ground vibrates severely in the horizontal direction, and the upper structure is greatly amplified and shaken compared to the movement of the ground. .

As a result, domestic seismic design has been strengthened to apply the seismic standards to KBC-2016 with more than two floors and a total floor area of less than 500㎡, and is strictly applied to non-structural elements (ceilings, curtain walls, facilities, etc.).

Among the non-structural elements, seismic design applications for mechanical and fire-fighting systems are to be applied from 2016. The seismic design of mechanical equipment and fire-fighting equipment basically guarantees stability against the input seismic load, but there is no method to secure the seismic performance of piping by reducing the response acceleration to the input seismic load. .

In order to secure the seismic performance of pipes, some domestic and foreign related companies install braces at the connection of pipes and structures, or install vibration joints at the connection parts of pipes to absorb vibration energy or apply seismic hangers using elasticity.

As an example of a brace, a domestic shockproof performance reinforcing supporter is disclosed in Korean Laid-Open Patent Publication No. 10-2019-0107853.

The pipe seismic performance reinforcing support is installed in the outer peripheral portion of the pipe as shown in Figure 1 and a cylindrical clamp for fixing the pipe, and connected to the side of the clamp, the vertical surface of the longitudinal direction of the pipe with respect to the ceiling surface The first support 200 is installed inclined 40 to 50 ° on the top, and the second support 300 is connected to the side of the clamp, 50 to 70 ° tilted on a vertical surface in the width direction of the pipe with respect to the ceiling surface and The anchor bolt 400 is bored on the ceiling surface is connected to one end of the first support and the second support.

In addition, an example of an elastic joint is disclosed in Korea Patent Publication No. 10-1922419.

The seismic piping connection device is coupled to the outer peripheral surface of the end of one pipe which is installed in contact with each other, as shown in Figure 2, an O-ring is installed on the inner peripheral surface and the outer peripheral surface, the outer peripheral surface in a direction away from the contact surface of the pipe The first fixing ring 10 is formed with an inclined surface that becomes thinner and thinner, and is coupled to the outer circumferential surface of the end of the other pipe which is installed in contact with each other, and an O-ring is installed on the inner circumferential surface and the outer circumferential surface, and the outer circumferential surface of the pipe The second fixing ring 20 is formed as an inclined surface thinner toward the direction away from the contact surface, the first fixing ring 10 and the side of the first fixing ring 10 is installed in close contact with the first fixing ring 10, The first flange member 30 coupled to the outer circumferential surface and formed with a plurality of fastening holes at intervals along the circumference and the outer circumferential surface of the second fixing ring 20 and spaced along the circumference A number of fastening holes are formed, and the second flange member 40 and the first flange member 30 and the second flange member 40 which are installed in contact with the first flange member 30 are integral with each other. It consists of a plurality of fastening members 70 to fasten by fixing.

In addition, as an example of an earthquake-resistant hanger, a seismic isolator for firefighting pipes is disclosed in Korea Patent Publication No. 10-1897621.

As shown in FIG. 3, the seismic device of the fire fighting pipe includes a pair of support brackets 40 fixed to the ceiling; and a base panel 20 to which the pipe 10 is fixed by a fastening bolt 11; And the upper portion is coupled to the support bracket 40 by a hinge 31, the lower portion is composed of a pair of sober 30 is coupled to the base panel 20 by the hinge 32.

However, since all of these seismic devices absorb the impact of vertical and horizontal vibrations of the pipes, there is a problem that bending occurs due to compressive force or load on the pipe itself when an earthquake occurs, and bending occurs due to compression force or load. If there is a problem that the connection or the pipe itself is broken.
