In the present invention, the steel strip is attached to the shaped steel support by inserting a pin inserted into a pin hole furthest from the tension receiving member into the eye ring end of the steel strip, and attaching the steel strip to the shaped steel support. Each of the pipes placed thereon and each of the pins inserted into the respective pin holes of the shaped steel support member are alternately and sequentially wrapped around the tension bolt at the other end of the steel strip and the tension nut applied to the tension bolt. If the steel strip is tightened by screwing this tension nut into the tension bolt, the tensioned steel strip will be
Since it is going to be in a state of passing through the shortest path among the shapes wrapped around each pipe and each pin, the position of each pipe is forced to be in the middle position between each pin. Further, since the tension is the same everywhere in the steel strip, each pipe is uniformly and simultaneously pressed down on the section steel support member with the same tension of this steel strip, and fixed and supported. If the pipe pressed against the steel strip moves in any direction in the plane perpendicular to the axis, the pipe will deviate from the shape that is the shortest path of the steel strip, and will have the shape of the shortest path of the steel strip. The movement of the pipe is prevented by the tension that is going to be applied. Further, even if the pipe moves in the axial direction, the frictional force between the pipe and the steel strip and between the pipe and the shaped steel support member, and the movement of the pipe is prevented by the in-plane shear force of the steel strip. . That is, the pipe pressed by the steel strip against the shaped steel support member is fixed and supported so as not to move in any of the vertical, horizontal, and front and rear directions.

As shown in FIG. 1F, one end of the steel strip 5 is folded round so that the pin 4 can be inserted, and an eye ring end 5e is formed. At the other end, a tension bolt 6 having a screw portion of a required length is attached. Reference numeral 7 denotes a tension nut screwed into the tension bolt 6. Tension nut 7 is 1
Although a single nut may be used, a double nut is shown in the figure to prevent loosening. Reference numeral 8 denotes a tension receiving member, which is attached to the end of the section steel support member 3 so as to receive the tension nut 7 screwed into the tension bolt 6.

As shown in FIG. 1, a section steel support member 3 made of, for example, a channel steel material is provided on both sides of a group of parallel pipes 2 (each outer side of the outermost pipe 2) and each pipe 2 A pin hole 3h is formed at a position corresponding to the middle (a total of five places because four pipes 2 are shown in the figure). Pin hole 3
h is provided in a direction parallel to the lateral direction of the shaped steel support member 3 or the axial direction of the pipe 2. The steel strip 5 is a thin plate made of a tough material such as a stainless steel plate, for example, and has such a length that the pins 4 and the pipes 2 can be looped and tensioned as shown in FIG. The width of the steel strip 5 is, for example, a width that enters the inside of the section steel support member 3. The thickness of the steel strip 5 is determined so as to be easily bent to the curvature of the diameter of the pin 4 and to withstand a sufficient tension. Further, the diameter of the pin 4 has a sufficient rigidity against a bending moment applied to the pin 4 due to the tension of the steel strip 5 and a diameter large enough to prevent the steel strip 5 from being forcibly bent. . As shown in FIG.
As shown in (G), a receiving hole or notch 8c is formed to receive the tension nut 7 into which the tension bolt 6 is inserted and screwed into the tension bolt 6. The receiving hole or notch 8c may be formed as a notch or a hole having a diameter slightly larger than the diameter of the tension bolt 6 as shown in the drawing.

Next, a description will be given of an installation procedure for fixing and supporting the pipe 2 on the pipe support device shown in FIG. First, as shown in FIG. 3A, the pipes 2 are placed side by side on the section steel support member 3.

Is positioned, and the pin 4 is inserted through the pin hole 3h at the right end of the drawing and the eye ring end 5e to thereby make the pin hole 3 at the right end of the drawing.
At a point h, the steel strip 5 is attached to the shaped steel support member 3 with the pin 4.

Next, as shown in FIG. 3 (B), the steel strip 5 was pushed down at a location between the pipe 2 on the right end of the figure and the pipe 2 adjacent thereto, and was pushed down into the pin hole 3h at that location. The pin 4 is inserted so as to pass over the steel strip 5. Then, for the pin hole 3h between the pipes 2 on the left sequentially,
The steel strip 5 is pushed down at a position between the pipe 2 and the pipe 2 adjacent thereto, and the pin 4 is inserted into the pin hole 3h so as to pass over the pushed down steel strip 5. Finally, the steel strip 5 is passed under the left end pin 4 in the figure, and the tension bolt 6 attached to the end of the steel strip 5 is pulled out to the left.

As described above, the steel strips 5 are alternately wound around the pipes 2 and the pins 4 in turn, and all the pins 4 are inserted and mounted. Then, as shown in FIG. Receiving hole or notch 8 of tension receiving member 8 attached to the end of steel support 3
When the tension nut 6 is passed through the tension bolt 6 and the tension nut 7 is screwed into the tension bolt 6, the tension nut 7 is received by the tension receiving material 8. The steel strip 5 pulled out to the left in the figure and connected to the tension bolt 6 is also pulled to the left. The eye ring end 5e at the right end of the drawing of the steel strip 5 is a pin 4 at the right end.
3 is attached to the shape steel support member 3 as shown in FIG.
As shown in (C), the steel strip 5 is tensioned, and the respective pipes 2 are simultaneously pressed and fixed to the upper surface of the section steel support 3 by the tension.

As shown in FIGS. 3B and 3C, the steel strip 5 alternately wound around each pipe 2 and each pin 4 is
When pulled as described above, the pipe tends to pass through the shortest path. However, when the pipe 2 is located at the middle position between the pins 4, the shortest path is provided. Due to the tension, each pipe 2 is fixed at the center position between each pin 4. In addition, the steel strip 5 to be pulled
Since the tension is the same everywhere, the pipes 2 are simultaneously pressed against the section steel support 3 with a uniform force and fixed by the uniform tension of the steel strip 5.

In this way, the pipe 2 pressed on the section steel support member 3 by the tension of the steel strip 5 is shown in FIG.
As shown with respect to the pipe 2 on the right side of (A) and (B),
Regardless of the direction in which the pipe 2 moves in the plane perpendicular to the axis, the pipe 2 deviates from the center position between the pin 4 and the adjacent pin 4, that is, deviates from the shape of the shortest path of the steel strip 5. , And the tension of the steel strip 5 prevents the pipe 2 from moving in the direction perpendicular to the axis. FIGS. 2A and 2B
As shown about the pipe 2 on the left side of the figure, even if the pipe 2 tries to move in the axial direction, the frictional force between the pipe 2 and the steel strip 5 and between the pipe 2 and the section steel support member 3 and the steel The in-plane shearing force of the band 5 prevents the pipe 2 from moving in the axial direction. That is, each pipe 2 pressed against the section steel support 3 by the steel strip 5 is simultaneously fixed and supported by a uniform force so as not to move in any of the directions of up, down, left, right and front.

Although the word "steel" is used in the names of the section steel support 3 and the steel strip 5, steel is the cheapest and widely used material having the toughness required for these members. Therefore, the material is not necessarily required to be steel. Various alloys or non-ferrous metals may be used. In some cases, an organic polymer material or the like may be used as the steel strip 5. In addition, although the channel steel is illustrated as the section steel support member 3, a combination of angle irons or a section formed by processing a plate material can be used.
