In FIGS. 11 and 12, the upper holding member 51 and the lower holding member 52 have arcuate parts 51A and 52A made by bending the plate material into a semicircular arc, so that In order to bring the arcuate parts 51A and 52A into contact (pressure), there is a demand for a gap of 1 mm or less, and it is necessary to curve the plate material with high precision.
To perform this curving process, a male press mold corresponding to the outer diameter of each pipe P is required, and hot pressing may be required to create the curvature, which requires the operator's skill and is dangerous work. However, there was a problem in that it took time and effort to manufacture.

Furthermore, as can be seen from FIGS. 11 and 12, the arcuate strip 51B must be integrated with the upper arcuate portion 51A by "welding". On the other hand, a substantially trapezoidal support leg 52B having an arcuate notch 52C on the upper side must be integrated with the lower arcuate portion 52A by "welding". Moreover, since the reinforcing ribs 52E must be "welded" in the same manner, the structure requires high accuracy in hot pressing of the curvature of the arcuate portions 51A and 52A.
Because this type of "welding" process is required, it takes time and effort to manufacture, and there is also the problem of a shortage of skilled welders and the problem of quality and aesthetic deterioration due to the generation of distortion and spatter. there were.

The figure shows a heavy load type that can withstand large loads. Furthermore, as shown in FIGS. 4 and 5, screw holes 14, 14 are formed through the horizontal bottom of the outer plate 4B, and a fastening bolt 13 is screwed into the screw holes 14 to integrally connect both the inner and outer plates 4A, 4B. Connect in a shape.

By the way, as shown in FIGS. 1 and 2, two parallel guide rail members R, R are welded (or bolted, etc.) on the fixing surface 15 on which the pipe support device according to the present invention is attached (for attachment). It is preferable that the cross-sectional shape of each rail member R is an inverted L-shape.

The lower connection plate 4 has guided pieces 5, 5 projecting left and right. In addition, as shown in FIG. 5 and FIG. 6, when the lower connection plate 4 consists of two inner and outer plates 4A, 4B, rectangular protrusions 5A, 5A; 5B, 5B are formed on each, It is desirable to overlap them in terms of strength.

In this way, the guided piece 5 is slidably engaged with the guide rail member R, and the pipe P is reliably supported while controlling movement due to pipe expansion due to temperature changes.
