Description

Detailed Description of the Invention (a) Field of Application of the Invention The air membrane structure is a structure in which members are stretched over a hemispherical roof surface where cables are crossed, and the membrane material is made rigid by creating positive air pressure inside the room. It gives support to the roof surface.

The stretched cables need to cross each other accurately at a predetermined position, and it is also necessary to maintain the crossed state.

Therefore, the present inventor has previously proposed an intersection point support at the intersection of cables and a stopper for maintaining the position of this support.

However, when attaching the intersection support and the stopper to the cable, the work of attaching them to the correct position on the cable is extremely complicated.

(b) Object of the present invention The present invention makes it possible to accurately, easily and quickly attach such an intersection support and a stopper to a cable.

(C) Structure of the Present Invention A feature of the present invention is that marks are provided in advance at each attachment position of the intersection support to the intersection of the cables and the stopper body outside thereof.

This mark is made by coloring and is made the same as the axial length of the intersection support and the stopper.

Furthermore, it is convenient to use different colors for the marks for the intersection support and for the stopper.

Furthermore, if the mark for the intersection support is divided at the intersection of this cable and the cable it intersects with, the position of the other cable to be intersected can be easily determined, and the installation work for this cable will be accurate, easy, and quick. can be done.

(d) Embodiments Embodiments of the present invention will be described based on drawings. Cables 2 are stretched across the first cable constructed as shown in the first figure to form a roof surface.

By the way, an intersection point support is attached to each intersection P of the cable 2, but since the cable is constantly subjected to expansion force due to wind pressure and internal pressure, this support may move outward (toward the beam). . To prevent this movement, a stopper is provided on the outside of each intersection support. This 411 structure is shown in Figures 2 to 5 /Jet, so first of all, the structure of the intersection support 3 is as shown in Figure 2 7J1,
The cable 2 has semi-tubular clamping bodies 4 and 5 that are divided into two parts in the axial direction so that they can be fitted from above and below, and on the upper surface of the upper clamping body 4 there are semiconductor-shaped clamping bodies for wires that intersect at a predetermined angle. body 6
are fixed by a continuous member 7 at a predetermined intersection angle. In addition, a base plate 8 (planar shape is shown in Fig. 3) is attached to the lower clamping body 5.
is fixed horizontally. The base plate 8 has U bolts 9
A through hole 8a is bored through which the threaded band 9a passes, and a semi-tubular clamping body 10 is formed on the inner surface of the arcuate portion of the U-bolt, facing the clamping body 6 for the crossing cables. is fixed. Therefore, by inserting the U bolts 9 into the through holes 8a, . taught in a crossed position.

Next, on the outside of the intersection support 3 (left side in FIG. 3), a stopper 13 is fitted onto the cable 2. As shown in the fourth figure, the shape of the stopper 13 is such that two upper and lower clamping bodies 14 and 15 are fastened together with a bolt 16 and a nut 17, and each of the clamping bodies has a fitting groove 14a for a cable on its inner surface. 15a are each sprouted.

By the way, the cable 2 to the intersection support 3 and the stopper 13
, 2a will be explained based on FIG.

At the attachment position of the intersection support 3 on one cable 2, a mark A is pre-marked in two parts, with the right half marked in red A1 and the left half marked A2. The boundary between red and blue corresponds to the position of the crossing cables 2a, and the length of this layer color (mark) corresponds to the length of the clamping body 4.5 of the intersection support 3.

Further, a green mark B is attached to the mounting position of the stopper 13 of the cable 2, and the length of this mark matches the length of the clamping bodies 14 and 15 of this stopper.

Therefore, first align the clamps 4 and 5 of the intersection support 3 with marks A and B on the cable 2, and then
It is only necessary to stack the U-bolts 9 from above on the clamping body 6, pass the threaded portions 9a through the through-holes 3a of the base plate 8, and tighten them with the bolts 11 and 12. Also, to attach the stopper 13 to the cable 2, align the clamps 14 and 15 of this stopper with the marks, and attach the bolts 16 and
All you have to do is tighten the nut 17.

(e) Effects Since the present invention has the above-described configuration, the work of attaching the intersection support and the stopper is accurate, easy, and quick.
