Description

Pipe Fixing Device {DEVICE FOR FIXING PIPE}

The present invention relates to a pipe fixing device, and more particularly, to a pipe fixing device that allows the pipe to be fixedly spaced from the floor or wall surface.

As is well known, pipes are mostly used in piping so that fluids such as liquids, gases, etc. can be transported and supplied from one place to another using pressure differentials.

In general, when the pipe is exposed to the outside, it is preferable to install it at a predetermined distance or more away from the floor or the wall to avoid contamination or corrosion.

As such, a pipe fixing device is used to fix and install the pipe away from the floor or the wall.

Conventionally, the pipe fixing device is fixedly installed on the floor or wall surface to be supported bracket (Bracket) having a bent portion, and screwing the U-shaped fixing bracket on the upper side of the support bracket using a screw fastener to the bent portion of the support bracket Configured to secure the seated pipe.

However, in the conventional pipe fixing device, when the floor or wall to which the pipe is to be installed is uneven, the pipes are parallel to a constant height because both leg portions of the support bracket fixed to the floor or the wall are made uniform with the same height. There is a problem that can not be installed.

In addition, in order to solve the above problems, it is necessary to make and use each support bracket having different heights of legs according to the smoothness of the floor or wall to which the pipe is to be installed. Has the disadvantages required.

In particular, it is necessary to make the piping with an accurate gradient according to the type of fluid to be conveyed, or to adjust the installation height of the pipe more precisely when sagging and twisting are easily caused by the external environment depending on the material of the pipe.

An object of the present invention for solving the above problems, the pipe fixing device to more precisely adjust the height of the fixed feet on both sides of the pipe fixed installation in accordance with the smoothness of the floor or wall to install the pipe when pipe piping To provide.

Pipe fixing device of the present invention for achieving the above object, the pipe seat portion in the center is formed to be bent downward in a semi-circular shape, the height adjustment nut is free in each of the first fastening hole passing through the lower horizontal extension of both sides of the pipe seat portion A lower support rotatably inserted and fixed thereto; Both upper horizontal extensions are screwed up on the lower horizontal extension above the lower support, and the pipe fixing portion between the upper horizontal extensions is semicircular so as to surround and secure the upper part of the pipe seated on the pipe seat of the lower support. An upper fixture formed to be bent upwardly; And a lower fixing part of the upper fixing part is formed at each of the upper end and the lower end of the leg vertical part, and the lower fixing part is fixed by the respective screw fasteners passing through the height adjusting nuts of the lower horizontal extension on both sides of the lower supporting part. And a fixing leg fixedly fastened to a height adjustable pitch per bottom from the fixed bottom surface, wherein the height adjusting nut is provided with a locking head at a lower end to be inserted into and fixed through the fastening hole of the lower support. A bushing in which the screw fastener is inserted and screwed therein; And a nut that is fitted with an upper end of the bushing to be integrally press-fitted.
Here, the lower support preferably further includes a lower vertical extension extending vertically downward from the end of the lower horizontal extension.
In addition, at both ends of the width direction of the lower vertical extension part, a guide bent part may be formed to be bent and wrapped at both ends of the width direction of the leg vertical part of the fixing leg.
In addition, the lower vertical extension portion penetrates in a vertical direction and is formed with a vertical guide hole, and the guide protrusion is formed to protrude outward from the leg vertical portion of the fixing leg so as to fit in the vertical guide hole.
In addition, the fixing leg is preferably formed in the longitudinal fastening of the leg fastening hole in the longitudinal direction of the lower fixing portion.
