The pressing support 220 is configured to slide in the outward direction from the center of the guide frame 210 formed in a ring shape, it can be pressed in the direction of the center of the guide frame 210 that is inside.

At this time, the pressing support 220 may be guided by the guide slit 212 described above.

In other words, the pressing support 220 may be coupled to the guide frame 210 so as to penetrate the guide slit 212 in the space 211 and be exposed in the center direction of the inside of the guide frame 210.

Meanwhile, the pressing support 220 may include a pressing pad 221, a guide blade 222, and a supporting plate 223 as shown in FIG. 3.

The pressure pad 221 is exposed to the inside of the guide frame 210 to press the outer peripheral surface of the pipe, it may be formed in an arc shape corresponding to the shape of the inner (center direction) surface of the guide frame 210. In this case, the pressure pad 221 may be formed in a horizontal curved shape in order to support the pipe stably.

In addition, since the pressure pad 221 is pressed in the inner direction of the guide frame 210 by the elastic force of the elastic sphere 230 is in close contact with the outer peripheral surface of the pipe, the curvature of the contact surface corresponding to the outer peripheral surface of the target pipe to be configured Can be.

In this case, the curvature deformation of the pressure pad 221 may include a deformation by a material or a deformation by a structure. For example, when the curvature of the pressure pad 221 by the material, the pressure pad 221 may be formed of a synthetic resin material. As another example, when the curvature of the pressure pad 221 by the structure, the pressure pad 221 may include a leaf spring that is deformed by the bending moment.

The support plate 223 is horizontally connected to the other side of the guide blade 222 extending toward the space 211 and may be positioned in the space 211 of the guide frame 210.

Thus, by supporting the elastic sphere 230 configured in the space portion 211 in contact with the support plate 223, it is possible to press the pressing support 220 in the inner direction of the guide frame 210.

At this time, the support plate 223 is formed in the horizontal direction, while being caught on the inner surface of the space portion 211 in which the guide slit 212 is formed, the pressure is pressed into the guide frame 220 by the elastic sphere 230 The support 220 may also serve to prevent the guide frame 210 from being separated.

On the other hand, the elastic sphere 230 is formed in a waveform as shown in Figures 2 and 3 in order to be able to support the inner upper surface of the support plate 223 and the space portion 211 at many points in one configuration Can be.

For example, the corrugated elastic sphere 230 contacts the support plate 223 with the valleys 231, and the floor 232 contacts the outer inner surface (upper surface) of the inner surface of the space portion 211. By doing so, it is possible to obtain the effect that the force of the vibration applied to the floor 232 is distributed to the valleys 231 on both sides.

4 is a cross-sectional view illustrating another embodiment of the pipe mounting portion shown in FIG. 1, and FIG. 5 is a view for explaining the function of FIG. 4.

Referring to FIG. 4, a guide rib 213 may be formed in the space 211 of the guide frame 210 to guide the movement of the support plate 223 of the pressing support 220.

The guide rib 213 also restricts the movement of the elastic sphere 230, it is possible to prevent the elastic sphere 230 is separated from a predetermined position to prevent supporting the support plate 223.

When the pressure pad 221 supports the pipe P as shown in FIG. 5, the curvature of the contact surface is deformed so as to correspond to the outer circumferential surface of the pipe P as described above, thereby reducing the outer circumferential surface of the pipe P. I can support it stably.

6 is a cross-sectional view for explaining another embodiment of the pipe mounting portion shown in FIG.

Referring to FIG. 6, in order to prevent the elastic sphere 230 from being separated from the support plate 223 of the pressing support 220, one side of the elastic sphere 230 is supported by the supporting plate 223 of the pressing support 220. Can be fixed at

More specifically, the elastic sphere 230 may be connected to the support plate 223 of the pressing support 220 by the connector 233.

At this time, the connector 233 can be formed by deforming the one end of the elastic sphere 230, as shown in FIG.

7 is a cross-sectional view illustrating still another embodiment of the pipe mounting portion shown in FIG. 1.

Referring to FIG. 7, in order to prevent the elastic tool 230 from being separated from the support plate 223 of the pressure supporter 220, the pressure supporter 220 is configured in the support plate 223 and is provided with the elastic tool 230. Guide strip 224 to limit the movement of the) can be further configured.

More specifically, the guide strip 224 may be formed to extend from the support plate 223 of the pressing support 220, the portion of the bone 231 of the elastic sphere 230 penetrates as shown in the enlarged portion of FIG. Can be.

At this time, considering that the shape of the elastic sphere 230 is deformed as shown in Figures 5 and 6 by the pressure due to vibration, the guide strip 224 is irregularly shaped portion of the bone 231 of the elastic sphere 230 It is preferable to be formed to enable flow.

In other words, the guide strip 224 may be formed to allow a certain degree of movement in a state where the valley 231 portion of the elastic ball 230 penetrates the guide strip 224.

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

Referring to FIG. 8, 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 Figure 8), and the attraction force (in Figure 8) 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, 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.

FIG. 9 is a perspective view illustrating another embodiment of FIG. 1, FIG. 10 is a view for explaining a buffer support unit shown in FIG. 9, FIG. 11 is a view for explaining the function of FIG. 10, and FIG. 12 is a view of FIG. 9. It is a figure for demonstrating a function.

9 and 10, 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 may include a buffer hole 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. 8, but the torsion such as yawing due to the structure capable of three-axis rotation. Can reduce the effects of

More specifically, since the coupling angle due to torsion is changed at the portion where the buffer port 330 is connected to each connector, even if the pipe itself is twisted by rotation such as yawing or the like, 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, 10 and 11 are preferably coupled to the ball joint (311, 321).

On the other hand, when the shock absorbing port 330 is exposed as shown in FIG. 8, 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 10 to protect the elastic spring from the outside and to 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 attractive force (a box-shaped arrow in FIG. 10) between the first connector 310 and the second connector 302.

At this time, the elastic spring 333 may be configured to generate a repulsive force (solid arrow in Figure 10) without generating an attraction 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 support 200 is supported by the buffer support 300 of the ball joint structure, various irregular vibrations can be effectively attenuated as shown in FIG. 12.

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

FIG. 13 is a diagram illustrating still another embodiment of FIG. 1. FIG.

Referring to FIG. 13, 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.

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. 13, in the case where the connecting buffer support unit 300 ′ is formed between the two pipe mounting units 200, when any one pipe is moved to the neighboring pipe side, the connecting 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 double-sided seismic structure ceiling mounting bracket for 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.
