It is shaped like a letter and its material is preferably metal or plastic.

The saddle 4 is preferably made of plastic, but may be made of metal, and is fixed to the mount 3 so as to be detachable and movable. 2 and 3 are partial sectional views showing a fixed state of the saddle 4 of the pipe shaft according to the embodiment of the present invention. In the case of FIG. 2, the saddle 4 has a grip portion 5 for gripping the pipe 11 or the header 9 and a fitting portion 6 for fitting with the outer edge of the pedestal 3, and is fitted to the pedestal 3 and is detachably and movably fixed. It When the saddle 4 is moved in the longitudinal direction of the gantry 3 after this, the saddle 4 is removed from the gantry 3 and the same gantry 3 is removed.
It can be moved in the left-right direction by fitting it in another position. Further, the saddle 4 can be moved in the vertical direction by fixing it from the pedestal 3 which is already fixed to another pedestal 3 which is located above or below the removal frame 14.

In the case of FIG. 3, the saddle 4 has a grip portion 5 for gripping the pipe 11 or the header 9, a plate 7 for sandwiching the outer edge of the pedestal 3 together with the grip portion 5, the grip portion 5, and the plate 7.
The saddle 4 is detachably and movably fixed to the pedestal 3 by being configured by a bolt 8 that connects the pedestal 3 and the outer edge of the pedestal 3 between the grip portion 5 and the plate 7. After that, the bolts 8 are loosened and the saddle 4 is slid in the longitudinal direction of the gantry 3 so that it can be moved in the left-right direction. After determining the position of the saddle 4, the bolt 8 is tightened to fix the saddle 4 to the pedestal 3. Further, the saddle 4 can be moved in the vertical direction by fixing it from the pedestal 3 which is already fixed to another pedestal 3 which is located above or below the removal frame 14.

The header 9 has a plurality of connecting portions 10 for connecting with a plurality of pipes 11 and has a hollow cylindrical shape. The material thereof is preferably plastic or metal and can be fitted into one or more saddles 4. It is sandwiched by the saddle 4 and is detachably fixed. The header 9 together with the saddle 4 is the mount 3
It can be moved left and right by sliding it in the longitudinal direction. Further, the header 9 becomes movable in the vertical direction as the saddle 4 moves in the vertical direction as described above.

The material of the pipe 11 is preferably plastic or metal, and the pipe 11 is connected by being pushed into the connecting portion 10 of the header 9 and is inserted into one or more saddles 4 so as to be sandwiched between the saddles 4 and detachable and movable. It is fixed freely.

The position of the header 9 or the pipe 11 will be described below.
The case of moving from an already fixed position to another position during manufacture of the pipe shaft or during construction at a construction site is described below. First, the saddle 4 having the header 9 or the pipe 11 sandwiched therein is removed from the pedestal 3 which is already fixed. After that, the saddle 4 with the header 9 or the pipe 11 sandwiched therein is fitted into the desired horizontal position of the gantry 3 at the desired vertical position. As a result, the position of the header 9 or the pipe 11 can be moved vertically and horizontally.

The pipe shaft described above can also be used by being fixed to the H-section steel 15 used as a beam of a building. FIG. 6 is a perspective view showing a pipe shaft fixing structure according to still another embodiment of the present invention. FIG. 7 is a perspective view of an upper fixing member and a lower fixing member used in the pipe shaft fixing structure of the embodiment. The fixing structure of the pipe shaft will be described with reference to FIGS. 6 and 7. In this pipe shaft fixing structure, the pipe shaft is fixedly installed on the upper H-shaped steel 15 and the lower H-shaped steel 15 via the upper fixing member 16 and the lower fixing member 17. The H-shaped steel 15 is used as a beam for the floor and a beam for the ceiling. That is, if it is a one-story building, it is used as a beam for the floor and ceiling, and if it is a two-story building, it is used as a beam for the boundary between the first and second floors and the ceiling of the second floor. Therefore, the H-shaped steel 15 on the upper side indicates the one above, and the H-shaped steel 15 on the lower side indicates the one below.

Although this pipe shaft is similar to the pipe shaft shown in FIG. 1, the basic structure of the pipe shaft is different from that of FIG.
Is the same as that shown in.

Has an L-shaped member 22 attached thereto. A mounting elongated hole 24b extending in the vertical direction is provided on the back surface of the L-shaped angle 20 at substantially the same interval as the mounting elongated hole 24a.

The procedure for fixing the pipe shaft to the H-shaped rope 15 will be described below. The upper fixing member 16 and the fixing piece 21 are fixed in advance by welding or the like.

At the construction site, while the pipe shaft is being lifted, with the upper part of the upper fixing member 16 suspended from the upper surface of the lower flange of the upper H-shaped steel 15, the fixed long hole 18 of the H-shaped steel 15 and the upper fixed part are fixed. The long holes 19 of the member 16 are aligned and temporarily fixed. In this way the pipe shaft and H
By arranging and fixing the fixing member and the like to the shape steel 15, the horizontal accuracy of the pipe shaft is automatically secured. Then, by adjusting the fixing position between the upper fixing member 16 and the lower flange upper surface of the H-shaped rope 15 by the fixed elongated holes 18 and 19, the width and the mounting position in the depth direction of the pipe shaft can be finely adjusted. .

Next, the fixed long hole 18 of the H-shaped steel 15 and the long hole 19 of the upper fixing member 16 are fixed with screws or the like.

Then, the L-shaped angle 20 arranged below the pipe shaft is fixed to the rear surface of the lower fixing member 17 which is previously fixed to the upper surface of the flange of the lower H-shaped steel 15 by screws or the like. The mounting position in the height direction of the pipe shaft can be finely adjusted by adjusting the fixing position of the angle 20 and the back surface of the lower fixing member 17 with the mounting long hole 24a and the mounting long hole 24b.
