Description

Pipe stand {A PIPE STAND}

[0001] The present invention relates to a pipe stand and, in particular, it is possible to adjust the height of a pipe to a correct working position and adjust the height so as to hold the pipes at the working position so as to perform piping work such as accurate pipe welding, The present invention relates to an improved pipe stand that is universally usable so as to be able to support a pipe.

Generally, piping work at a factory, ship, or building should maintain the level of the pipe at a certain height when the pipe piping system is installed close to the upper part of the wall or the ceiling. For this purpose, , And the pipe is supported at a certain height by bundling a separate bundling line to the spindle. In this case, since the ceiling is damaged because the concrete ceiling needs to be nailed, the work is troublesome and time consuming, I needed a pipe holder to support it.

Particularly, in the case of a marine pipe, its weight is very heavy and there is no structure to support the pipe, so that the above method can not be used. When a crane is used to support a pipe, it is difficult to center the pipes. Since the flange to be connected to the pipe is often more than 100 kg, it is necessary to use a universal holder that can align the center of the pipe and the flange and maintain the level.

For this purpose, as an example of a conventional pipe cradle, Korean Patent Laid-Open No. 10-2013-0001712 (Registered on Mar. 31, 2014) has proposed a "pipe cradle", and as shown in FIG. 1, Is a piping stand that is mounted to horizontally align a piping (400) installed in a wall of a building to an exact position, wherein a latching groove (11) is formed in a tongue shape on the upper side of a large circular pipe (10) A small circular pipe 20 having an upper and a lower closure inserted through an upper space of the circular pipe 10 and a hooking protrusion 21 A bolt 22 is formed at the upper center of the bolt 22 and a pipe fixture 30 for fixing the pipe to the bolt 22 is installed and the spring 40 and the guide plate 41 are inserted into the lower side , A small circular pipe (20) coupled to the large circular pipe And a pipe blocking plate 10a having a screw hole formed at the center of the large circular pipe 10 is installed on the bottom of the pipe blocking plate 10a, And the lower side of the elevation adjusting member 40 is connected to a supporting plate (not shown) having a fixing hole 52 formed therein so that the upper side of the elevation bolt fastened with the position fixing nut 41 is fitted through a screw hole 50, respectively.

However, such conventional technology can not mount pipes of various diameters, is limited in application to heavy-weight pipes used for ship piping work, and simply supports only one pipe at a certain height for pipe piping And it is inconvenient that the stability is not good and the movement is not easy. In order to weld the flange to the pipe, a mounting means for separately holding the flange was required.
