Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connection structure for roof membrane support plates in a membrane structure.

For example, in an air membrane structure, the entire structure is supported by air, so the cable has the characteristic of moving up and down under the influence of changes in internal pressure, wind pressure, etc. For this purpose, the roof membrane must follow the movement of the cable. If the cable and the roof membrane are not integrated, problems such as excessive force being applied to the roof membrane may occur.

The object of the present invention is to prevent excessive force from being applied to the roof membrane as the cable moves up and down.

The roof membrane support plates in the present invention are arranged above the cable at a predetermined distance along the cable, and between the opposing ends of the adjacent roof membrane support plates are the upper and lower connecting plates. and a bolt of a connector mounted upright on the cable. Clamping plates for clamping the cables are attached horizontally to the bolts of the coupling device above and below. Since the roof membrane support plates are connected by the connector, the distance between the roof membrane support plates and the cable is also maintained at the same time. The roof membrane support plate includes not only a flat plate but also a channel shape and a flat rectangular cylinder shape. The ends of adjacent roof membrane support plates have, for example, a shape formed by cutting a long plate diagonally or in a crank shape from one side toward the other, that is, they have an interlocking shape.

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

As shown in FIGS. 1 to 3, above the cables 1 and 1a that cross each other, roof membrane support plates 2, which constitute the main part of the roof membrane holder, are installed for a predetermined distance along each cable 1 and 1a. are placed consecutively. Note that the roof membrane support plate 2A and the roof membrane support plates 2A1, 2A1 intersect above the intersection of the cables 1, and the tips of the roof membrane support plates 2A1, 2A1 are on the same plane as the roof membrane support plate 2A. is connected to.

Opposing ends 2 of adjacent roof membrane support plates 2,...
A and 2a are spaced apart from each other by a predetermined distance 〓D,
Since the shape of each end portion 2a, 2a is formed in the shape of a cutting edge, the gap D crosses diagonally in the width direction of the roof membrane support plate 2, and the end portions 2a, 2a are in a state of interdigitating with each other. . A bolt insertion hole 2a1 (only the lower side is shown in FIG. 2) is formed in each roof membrane support plate end portion 2a, 2a. Roof membrane support plate end portions 2a, 2
a are connected to each other by a connecting tool 3 having a bolt 7 inserted through a bolt insertion hole 2a1,
Furthermore, the cable 1 is held and fixed at a distance above the cable 1.

The connector 3 is provided with upper and lower clamping plates 4 and 5 for clamping the cable 1 from both the upper and lower sides, and recesses 4a and 5a are provided on opposing inner surfaces of both clamping plates 4 and 5. By positioning the cable 1 in the upper and lower recesses 4a and 5a, the holding plates 4 and 5 can be positioned. The spacing between the holding plates 4 and 5 is ensured by spacer pipes 6 and 6 arranged on both sides.

Bolts 7, 7 pass through both sides of the holding plates 4, 5 and the spacer pipes 6, 6. Both bolts 7, 7 are connected to each other by a reaction force receiving plate 8 above the upper clamping plate 4. That is, as shown in FIGS. 4 to 6, a reaction force receiving plate 8 is placed between the bolts 7, 7, and pipes 9, 9 are fixed to both ends of the reaction force receiving plate 8. The bolts 7, 7 are inserted through the pipes 9, 9, and the portions through which the bolts 7, 7 are inserted are integrated with the pipes 9, 9 by welding. Therefore, the reaction force receiving plate 8 serves not only as a connecting plate for the bolts 7, 7, but also as a spacer plate between the clamping plates 4, 5 and a connecting plate 11, which will be described later. Therefore, by tightening the nuts 10, 10 attached to the lower ends of the bolts 7, 7 projecting below the clamping plate 5, the clamping plates 4, 5, the bolts 7, 7, and the reaction force receiving plate 8 are removed. They are integrally attached to the cable 1 in an upright position.

Furthermore, a connecting plate 11 is placed on the reaction force receiving plate 8 and the pipes 9, 9 as shown in FIG.

5, 15 are fixed onto the lower connecting plate 11 together with the upper connecting plate 11a by nuts 16, 16 attached to the upper ends of the bolts 7, 7. By tightening the nuts 16, 16, the roof membrane support plate ends 2a, 2a are connected to each other and to the cable 1 via the bolts 7, 7. At the same time, the rubber plate 12 and the cover plate 14 tightly sandwich the end of the roof membrane 13, ensuring airtightness. The cover plate 14 is bent upward to cover the entire length of the presser bodies 15, 15, and the locking sides 14a at the ends are inserted into the mounting grooves 17a provided on both sides of the gasket 17. There is. Reference numeral 14b is a bent portion formed on the cover plate 14 in advance. The lower engaging portion 17b of the gasket 17 is connected to the presser body 15,
By press-fitting the presser rod 18 into the groove 17c at the center of the upper part of the gasket 17, the locking side portion 14a is fixed to the gasket 17. The gasket 17 and the cover portion 14 more effectively ensure the airtightness of the roof membrane supporting portion.

Note that the intermediate portions of the presser bodies 15,...
As shown in the figure, it is fixed to the roof membrane support plates 2, 2A with bolts 19 and nuts 20, and the roof membrane 13 is also supported at the same time. The bolts 19 are fixedly erected on the roof membrane support plate 2 in advance.
