Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roof that can prevent the entire cable of a roof having an air membrane structure from moving outward from the center of the roof, for example.

A plurality of cables are stretched across the roof of the above structure, and the intersections of the cables are tied together with clamps. However, even if these intersection points are tightened, the clamp may slip during or after cable installation, causing the entire cable to move toward the outside of the roof, or protrude. If it is inside, there will be problems such as the inability to attach this membrane to the cable.

An object of the present invention is to provide a roof with a membrane structure that can reliably prevent cables from protruding at cable intersections.

The present invention is applicable to membrane structures such as air membranes and tension membrane structures, and is applicable to the cables outside the outermost intersection of a plurality of intersecting cables facing the outer periphery of the roof. , a stopper is provided adjacent to the clamp at the outermost intersection point to prevent the clamp from slipping due to the cable becoming entangled. Here, the outside refers to the side facing the outer periphery of the roof with the clamp at the intersection as the center.

Note that, if necessary, a stopper may be provided on the cable outside the intersection part that is inside the outermost intersection part.

This stopper consists of two clamping plates, a regular bolt or a U-shaped bolt, and a nut.The roof cable is sandwiched in the holding holes of both clamping plates, the clamping plates are connected with bolts, and the nuts are tightened. This connection is fixed by force.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a plurality of cables 1, 1a in two directions are connected at both ends to a ring-shaped beam 2, and intersect at the center of the roof, and each intersection 3,... is connected to a clamp 4,...( (Fig. 2).
Among the intersection points 3, ..., the outermost intersection point 3a,
A stopper 5,... is provided on the cable outside (left side in Figure 2).

This stopper, as shown in FIGS. 2 and 3, is adjacent to the clamp 4 and prevents the clamp from sliding outwardly (in the direction of the arrow in FIG. 2). The stopper 5 has two square-shaped clamping plates 6, 6a that clamp the cable 1a, and a holding hole 7 is formed in the center of the opposing surfaces of both clamping plates by a recess provided over the entire length. A cable is inserted through this holding hole, and the holding plate is held in position through this hole. Both clamping plates 6, 6a are connected and fixed at their four corners by bolts 8 and nuts 9. By the tightening force of this nut, both clamping plates 6, 6a are attached to the cable 1a through the holding hole 7. Therefore, even if the cable 1 tries to protrude and the clamp 4 tries to move in the direction of the arrow in FIG. 2, the side surface 5a prevents the movement.

The inner peripheral edge of the end opening on the outside (left side in FIG. 2) of the holding hole 7 is chamfered all around the edge to form a tapered surface 7.
A is formed. Therefore, even if the cable 1a moves vertically or horizontally, the cable 1a is
a, the cable does not come into direct contact with the inner peripheral edge, and the cable is not damaged.

If necessary, the stopper 5 may be attached to the outside of the intersection 3 inside the intersection 3a.

In order to facilitate the installation of the stopper 5, the fourth
As shown in the figure, a mark 10 having the same length L as the clamping plates 6, 6a is attached to the cable. In this way, the correct position of the stopper can be determined simply by aligning the edge of the clamping plate 6 with the end of the mark 10, and the mark is covered by the clamping plate and cannot be seen from below the cable.

As explained above, according to the present invention, a stopper is provided at the intersection of the cables, which is located facing the outer periphery of the roof, and which is closer to the end of the cable. This effectively prevents the cable from protruding, and the stopper is 2
Since it is equipped with two clamping plates, it can be attached even after the cable has been stretched.
