Examples of the ceiling mounting bracket for ceiling having a multi-axis vibration attenuation function according to the present invention can be applied in various ways, hereinafter with reference to the accompanying drawings will be described the most preferred embodiment.

1 is a block diagram showing an embodiment of a ceiling pipe holder having a multi-axis vibration damping function according to the present invention.

Referring to Figure 1, the ceiling mounting bracket (A) having a multi-axis vibration attenuation function of the present invention includes a base frame 100, the pipe mounting portion 200 and the buffer support 300.

The base frame 100 is fixed to the ceiling using an anchor bolt, etc., and may be configured in various shapes and structures according to the purpose of use, the size and number of pipes, the arrangement of the pipes, and the like.

Pipe mounting portion 200 is for mounting the pipe passing through the base frame 100, as shown in Figure 1 may be installed in the base frame 100 by a plurality of buffer support 300.

The shape of the pipe mounting portion 200 may be configured in a shape corresponding to the shape of the pipe or duct to be mounted, in the present invention will be described in the case where the pipe or the duct is circular in cross section.

The buffer support part 300 is configured to connect the pipe mounting part 200 and the base frame 100 by being arranged in a multi-axial direction based on the pipe mounting part 200, and from the base frame 100 to the pipe mounting part ( Attenuation of the vibration transmitted to the 200 may be performed.

In other words, the buffer support unit 300 supports to buffer the position change of the pipe mounting unit 200 and the base frame 100 according to the movement of the pipe.

At this time, the buffer support unit 300 is configured to be paired at a position symmetrical with respect to the center of the pipe mounting unit 200, as shown in Figure 1, thereby stably supporting the position of the usual pipe, of course, such as earthquake When external vibration occurs, the external vibration can be attenuated more efficiently, and after the vibration occurs, the pipe can be quickly returned to the original position while maintaining the original position stably.

In particular, considering that the seismic wave is generated in the P-wave of the vertical vibration and S-wave of the left and right vibration as described above, as shown in Figure 1, based on the center of the pipe mounting portion 200, up and down and left and right directions It is preferable to configure the buffer support portion 300 in each of the positions symmetrical to.

2 is a view for explaining the buffer support shown in FIG.

2, the buffer support part 300 may include a first connector 310, a second connector 320, and a buffer hole 330.

The first connector 310 is connected to the pipe mounting unit 200, and may be coupled to the outer circumferential surface of the pipe mounting unit 200 by a fastening or welding method using a bolt.

As shown in FIG. 1, the second connector 320 is connected to either the base frame 100 or the ceiling C. The second connector 320 may be coupled to the base frame 100 by a fastening or welding method using bolts. The ceiling (C) may be coupled to the anchor bolt.

The buffer port 330 is configured to connect the first connector 310 and the second connector 320, and may be configured to pull the pipe mounting portion 200 to the base frame 100 and the ceiling (C). .

Specifically, the buffer port 330 is formed to generate a attraction force (solid arrow in FIG. 2), and the attraction force (in FIG. 2) between the first connector 310 and the second connector 320 by the action of the generated attraction force Box-shaped arrows). For example, the buffer port 330 may include a coil spring for generating an attraction force as shown in FIG.

On the other hand, the pipe mounting portion 200 may include a mounting frame 210 and the elastic pad 220 as shown in FIG.

Mounting frame 210 is formed in a ring shape and the buffer support 300 is coupled, it may be composed of a metal material.

The elastic pad 220 is configured inside the mounting frame 210 to be in close contact with the outer circumferential surface of the pipe, and to prevent condensation and heat loss due to a temperature difference between the pipe through which the cold or hot water passes and the mounting frame 210. It can be configured as.

In particular, since the elastic pad 220 is composed of a synthetic resin material, when vibration is generated from the outside, a buffer effect between the pipe and the mounting frame 210 can be obtained.

On the other hand, in the structure as shown in Figure 1, when the pipe is shaken atypically by the vibration from the outside, the coil spring, which is the buffer port 330 of the buffer support unit 300 has a certain buffering effect against torsion as well as up and down vibration. Can be exercised.

However, if this torsion exceeds the limit value, the coil spring may be deformed. If the coil spring is deformed, the damping effect in the linear direction is weakened, and thus the corresponding configuration must be replaced.

Hereinafter, a method in which the buffer support part 300 of the present invention can be used semi-permanently while effectively attenuating the vibration as well as the vibration in the linear direction will be described.

Here, the vibration against torsion is not a vibration directly generated by an earthquake, but is a staggered vibration caused by the interaction of each component by the up and down and left and right vibrations caused by the earthquake. Without being limited, torsional vibration may be generated by various external forces.

3 is a perspective view illustrating another embodiment of FIG. 1, FIG. 4 is a view for explaining the buffer support unit shown in FIG. 3, FIG. 5 is a view for explaining the function of FIG. 4, and FIG. It is a figure for demonstrating a function.

Referring to FIGS. 3 and 4, the first connector 310 coupled to the mounting frame 210 and the first connector 320 attached to the base frame 100 or the ceiling C are buffered holes 330. And can be combined to enable three-axis rotation.

In other words, when torsional vibrations other than linear vibrations occur, the torsional vibration is not attenuated in the buffer port 330 itself as in the case of FIG. Can reduce the effects of

More specifically, since the coupling angle due to the torsion in the portion where the buffer port 330 and each connector are connected, even if the pipe itself is twisted by a rotation such as yawing, as shown in FIG. Since 330 only needs to attenuate the vibration in the linear direction without considering the influence of the torsion, it is possible to prevent the deformation of the coil spring to the torsion as described above.

As such, the three-axis pivot structure between the first connector 310 and the second connector 320 and the shock absorber 330 may be changed by those skilled in the art to various ones, in order to make the structure simple and easy to maintain, As shown in FIGS. 4 and 5, the ball joints 311 and 321 are preferably coupled to each other.

On the other hand, when the shock absorbing port 330 is exposed as shown in FIG. 2, damage or deformation may occur due to carelessness by an operator or a user, and in particular, since attenuation due to vibration is not made uniformly, As this elapses, the elastic spring may be deformed or its function may be degraded.

In order to prevent this, the present invention can apply a cylinder structure as shown in Figure 4 in order to protect the elastic spring from the outside and maintain its function continuously.

Specifically, the shock absorbing port 330 of the present invention is a cylinder 331 connected to the first connector 310 and the ball joint 311, and a piston connected to the second connector 320 and the ball joint 321. Rod 332 may be included.

In addition, the inside of the cylinder 331 may include an elastic spring 333 for generating an attraction force (a box-shaped arrow in FIG. 4) between the first connector 310 and the second connector 320.

At this time, the elastic spring 333 may be configured to generate a repulsive force (solid arrow in Figure 4) without generating an attractive force, in order to minimize the deformation caused by the external factors, the first connector ( An attractive force may be acted on between the 310 and the second connector 320.

As such, when the pipe mounting unit 200 is supported by the buffer support unit 300 of the ball joint structure, various irregular vibrations may be effectively attenuated as shown in FIG. 6.

In addition, such a structure can be extended to a structure capable of supporting a plurality of pipes, which will be described below.

7 is a configuration diagram illustrating still another embodiment of FIG. 1.

Referring to FIG. 7, when a plurality of pipes pass through one base frame 100, two neighboring pipe mounting parts 200 may be connected by a buffer support part 300 ′ for connection. That is, at least one buffer support part 300 of the buffer support part 300 is connected to one end is coupled to the pipe mounting portion 200, the other end is coupled to the pipe mounting portion 200 of the other adjacent pipe. It is composed of a buffer support (300 ').

As such, when the buffer support unit 300 ′ for connection is formed between two neighboring pipe mounting units 200, the two neighboring pipes may be prevented from colliding with each other by vibration.

For example, when a separate frame (not shown) is configured between two neighboring pipe placing parts 200, and the two pipe placing parts 200 are connected to the frame, two adjacent pipes are connected to the base. Since the vibration is independently in the frame 100, it may occur in the case of bumping each other in the process of vibrating atypically with each other.

However, as shown in FIG. 7, when the connection buffer support unit 300 ′ is formed between two pipe mounting units 200, when any one pipe is moved to a neighboring pipe side, the connection buffer support unit 300 ′ is connected. Since the neighboring pipes are pushed by), the distance between the two pipes can be kept constant, thereby preventing the two pipes from colliding with each other.

As a result, the present invention can ensure the stability of each pipe while expanding the arrangement of the pipe by using the buffer support portion 300 'for connection, and can be expanded in the horizontal direction as well as the vertical direction, various arrangement structure It can be applied smoothly.

In the above, the ceiling pipe holder having the multi-axis vibration attenuation function according to the present invention has been described. Such a technical configuration of the present invention will be understood by those skilled in the art that the present invention can be implemented in other specific forms without changing the technical spirit or essential features of the present invention.

Therefore, the above-described embodiments are to be understood in all respects as illustrative and not restrictive.
