Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a membrane support arrangement for cable crossings in the roof of a membrane structure.

For example, since the air membrane structure is supported by air, the structure as a whole tends to deform due to internal pressure or wind pressure. Therefore, a structure that can always follow this deformation is required.

The object of the invention is to provide a membrane support device at cable crossings that can meet the above requirements.

A feature of the present invention is the movable connection between membrane supports of a predetermined length that intersect above the cable intersection. That is, above the intersection of one cable running parallel to each other and the other cable running across these cables, there is a membrane that supports the roof membrane on its upper surface. A support is disposed along one of the cables, and a pair of membrane supports placed opposite each other are connected to both sides of the membrane support through connecting portions. The pair of opposing membrane supports support the membrane on the upper surface and are each disposed along the cable of the other. Both of the membrane supports along the other cable are connected and supported so as to be swingable about the connecting portion, with respect to the membrane support along the one cable. It is most desirable that both membrane supports located on both sides are movably connected to the membrane support along one cable, but even if only one of them is movably connected, the above purpose is achieved. can be achieved. The membrane support at the connection part can be connected by any appropriate method, such as a method in which the tip of the membrane support is made into a protrusion into the connection hole and the protrusion is inserted into the connection hole, or a method in which it is hooked into the connection hole as a hook. things are selected. The membrane support may be of any suitable shape, such as a flat plate or a channel type.
Further, the membrane support supports the roof membrane on its upper surface by means of support means.

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

In Figures 1 to 3, above the intersection of one cable C, which is stretched parallel to each other, and the other cable Ca, which is stretched in a direction that intersects these cables, one cable is A channel-type membrane support 1 with a parallelogram-shaped plane of a predetermined length is arranged along C, and a pair of channels with trapezoid-shaped planes are arranged on both sides of the membrane support parallel to the cable Ca. The molded membrane supports 2 and 2a intersect and their tips are connected to both sides of the membrane support 1 via connecting portions.

To explain the connected state, as shown in FIGS. 1 to 4, on both sides of the middle part of one membrane support 1, there are vertically long connecting holes 3, 3, which are connected support parts of the connecting part.
(Fig. 3) is open, and the other membrane support 2, 2
The tip of a is a protruding piece 4 which is a connecting support part of the connecting part,
4, and each protrusion is inserted and supported into the membrane support 1 through opposing connecting holes. Since the projecting pieces 4, 4 are loosely fitted into the connecting holes 3, 3, the membrane support 2,
2a can swing vertically and horizontally around this connecting hole.

The rear ends, that is, the outer ends (right end in FIG. 2) of the membrane supports 2, 2a stand up on the cable Ca via membrane retainers 5a, 5a attached to the upper surface, as shown in FIG. It is held by connecting fittings 6, 6, which are connecting supports for the cable and the membrane. That is, the rear end sides of the membrane supports 2, 2a are cut diagonally,
The edges of adjacent membrane supports 12, 12 are butted against each other (FIGS. 1 and 5). Membrane support 2, 2a, 12,
A pair of channel-type membrane retainers 5a, 15 are placed parallel to each other in the longitudinal direction on 12 and fixed by bolts 7, etc. (Fig. 3), and both membrane retainers 5a,
The membrane supports 2, 2a, 12, and 12 are abutted on the upper surfaces of opposite ends thereof so as to straddle each other. Then, as shown in FIGS. 2, 5, and 6, presser bodies 5a, 1
A fixing plate 8,... is placed across the upper surface of the abutting part of the membrane support member 5, and a receiving plate 6 of the connecting fittings 6, 6 is placed on the lower side of the membrane support.
a, 6a, and tighten the bolts 6b,
A fixing plate 8 is fixed to the upper end of 6b with nuts 6c, 6c, . . . . With this fixation, the membrane supports 2, 2
The rear end portion of a is connected to the membrane supports 12, 12 and is fixedly supported by connecting fittings 6, 6 at a constant distance above the cable Ca.

As shown in FIGS. 2 and 6, this connecting fitting 6 has two clamping plates 6d and 6e at its lower part, and the space between the clamping plates is held by a pipe-shaped spacer 6f. A connecting plate 6g is placed on the upper surface of the clamping plate 6d, and pipe-shaped spacers 6h, 6h are welded along the axial direction to both sides of the connecting plate. A receiving plate 6a is placed on the upper surface of the spacers 6h, 6h. Bolts 6b, 6b
protrudes above the membrane pressers 5a, 15 through the holding plates 6e, 6d, spacers 6f, 6h, and receiving plate 6a. By tightening the nuts 6i, 6i, the clamping plates 6d, 6e clamp the cable Ca, so that the connecting fitting 6 is fixed upright on the cable Ca.

Similarly, both ends of the membrane support 1 are fixed to the top of the connecting fittings by bolts 6b, 6b, . . . with nuts 6c, 6c.

Therefore, the intersecting membrane supports 1, 2, and 2a are supported at four points by connecting fittings 6 above the cables C and Ca at their ends. The membrane pressers 5, 5 on the membrane support 1 are also attached to the membrane support 1 by bolts 7 that stand up in advance on the membrane support 1, similarly to the case of the membrane supports 2, 2a. The membrane pressers 5, 5 are separated at the middle portion on the membrane support 1, as shown in FIG.

Here, the state of support of the roof membrane 9 on the membrane support 1 will be explained. As shown in FIG. 2, the upper surface of the membrane support 1 is covered over its entire length with a rubber plate 10,
Place the end of the roof membrane 9 on top of it, place the ends of the rubber covers 11, 11 that cover the pressers 5, 5 on this end, and press the rubber covers with the pressers 5, 5 from above. , nuts 7a, . . . are attached to the bolts 7 . Watertightness and airtightness of the fixed portion of the roof membrane 9 are ensured by the rubber plate 10 and the rubber cover 11. The rubber cover 11 is bent to cover the upper part of the membrane presser 5, and the edge of the rubber cover is inserted into the mounting groove of a gasket 13 which is press-fitted over the entire length between the membrane pressers. A fixing rod 14 is press-fitted into a recess at the center of the upper end of the gasket 13, and the gasket is fixedly supported on the membrane presser 5. Rubber cover 1
1 improves the watertightness and airtightness of the fixed portion of the membrane 9.

As shown in FIG. 3, the membrane 9 is supported on the membrane supports 2 and 2a in a similar manner to ensure watertightness and airtightness of the membrane fixing portion.

The rubber covers 11 and gaskets 13 on the membrane supports 1, 2, 2a are integrally provided in a cross-shape by integral molding or by gluing.

The intersection of cables C and Ca is the intersection clamp 16
This clamp 16 is not directly connected to the membrane supports 1 and 2, 2a, but is independent from them.

As explained above, according to the present invention, since the membrane supports that intersect above the cable intersection are movably connected, it is possible to follow the deformation of the structure due to internal pressure, wind pressure, etc., and force is applied to the membrane at the intersection. No force is applied.
