Description

The conduit suspending apparatus for the bridge}

The present invention relates to a suspension device for pipes installed in the lower part of the bridge, and in particular, the height adjustment is easy according to the bending of the bridge, and the bridge pipe suspension device for preventing the pipe breakage and leakage of the joint part by vibrating the bridge. It is about.

Modern bridges are built long in accordance with the development of technology, and street lights are installed for vehicles passing through the top of the bridge, and various electric devices such as sensors for checking the safety status of the bridge are installed with wires in the bridge. It is becoming.

In addition, the sewer pipe for collecting and discharging water from rainwater and a water supply pipe for operating a fire hydrant for fire suppression are installed in the bridge. .

On the other hand, the bridge is constructed so that the central part has a convex slope so that the bridge section is not made in a straight line, and the change of load according to the number of vehicles passing through the top plate of the bridge and the contraction and expansion of each member due to temperature, and the wind caused by bad weather Due to the deformation and the like, the bridge has a characteristic that its shape is changed, such as vibration and bending.

As the pipes constructed on the bridge are composed of several unit pipes connected to each other, the shape of the bridges may cause warpage in the unit pipes, causing cracks, or in particular, damage to joints that are weak in binding force. There is a problem of leaks in sewerage.

In addition, when vibration of the bridge is directly transmitted to the pipe, fatigue accumulates in the pipe, thereby shortening the life of the pipe.

On the other hand, in consideration of the case of hanging the pipe in the lower portion of the bridge construction, as the central portion of the bridge has a convex shape, a method for constructing the pipe horizontally is required. Conventionally, a method of adjusting the length of a wire or the like to suspend a pipe to a bridge in order to maintain a horizontal level, but the length adjustment of the wire is difficult to readjust the length once installed.

Alternatively, a bracket that supports the lower part of the pipe and is fixed to the lower part of the bridge is used, and the height of the pipe is adjusted by bolts at the bottom of the bracket. However, the force required to adjust the height directly with the bolt is a considerable problem is that the height of the pipe is not easy to adjust after the pipe is already installed.

The present invention is devised to solve the above problems, an embodiment of the present invention has the purpose of preventing the breakage of the pipe against deformation due to vibration, bending of the bridge.

Specifically, the purpose is to reduce the vertical vibration of the bridge to the pipe to transmit.

In addition, there is also an object to be able to easily adjust the height of the pipe installed in the lower portion of the bridge.

In order to solve the above problems, the present invention is an embodiment of the present invention, an outer buffer member for elastically wrapping the outside of the pipe and the first buffer portion provided with a clamp for fixing the outer surface buffer member to the pipe, and the lower portion of the first buffer portion A second cushioning portion having a lower buffering member for elastically wrapping the surface, a left and right side surfaces of the lower buffering member, and a lower arm fitted with an insertion groove to be fixed, and left and right sides of the second buffering portion The upper and lower sliding grooves which are coupled to be elevated are coupled to the main body and the lower plate of the bridge are provided with a left and right guide plate formed in the inner side, and a bottom plate formed in the lower portion of the guide plate to support the lower portion of the second buffer part. A coupling bracket, a hook bracket having a support piece having a through hole formed at a lower portion of the coupling piece, a support nail inserted into the through hole and fixed to the guide plate, and Proposes a suspension bridge pipe apparatus, characterized in that the side support portion and the third spring is provided which is located between the nail head of a nail comprising a buffer.

In addition, the upper surface of the lower shock absorbing member to reduce the contact area with the lower surface of the first shock absorbing portion is proposed bridge piping suspension device characterized in that the groove is formed.

In addition, an inclined surface is formed in the lower portion of the rest so that the center protrudes downward, the main body portion is slid along the rail formed on the bottom plate, the inclination corresponding to the inclined surface is formed on the top to hold the rest Screw rods coupled to the first and second supports to be formed on the outer circumferential surface of the first and second supports to move the first and second support plates in directions opposite to each other in a rotational direction, and protrude outward of the guide plate. The handle portion coupled to the screw rod, and the stopper penetrates the handle portion, the stopper for limiting the rotation of the handle portion as one end is fixed to the guide plate further provides a bridge piping suspension characterized in that it is provided .

According to the pipe suspension device for a bridge according to an embodiment of the present invention, by providing the first to third buffer parts, as the vibration and warpage of the bridge is significantly reduced and transmitted to the pipe, the damage of the pipe is prevented, the life of the pipe Has the effect of increasing.

In particular, the up and down vibration of the bridge, the third shock absorber is primarily absorbed, the second shock absorber secondly reduced the contact area is secondarily absorbed, and the first shock absorber that directly wraps the pipe absorbs additional vibration, such a vibration, Transmission to this pipe is minimized, thereby reducing the occurrence of defects such as fatigue fracture and cracks in joints.

In addition, the height of the pipe can be easily adjusted by the rotation of the handle, and the height of the pipe can be easily adjusted with little force by having a configuration that adjusts the height of the pipe by moving the first and second supports according to the rotation of the screw rod. Has the effect of being made.

This makes it possible to easily adjust the inclination of the pipe from time to time with respect to the bridge which is deformed due to bending during bridge construction or aging of the bridge, thereby increasing the service life of the pipe.
