Description

[Detailed explanation of the invention] (Industrial application field) This invention is applicable to sports facilities such as swimming pools and gymnasiums,
This invention relates to a device for attaching membrane ends in tension membrane structures that can be used in shopping facilities, exhibition halls, etc.

(Prior Art) In general, a tension membrane structure is one in which a roof membrane is suspended at each point or in a line by hanging bodies, and a constant tension is applied to the membrane. Conventionally, the means to support the edge of a roof membrane is to use, for example, two flat plates, which are stacked on top of each other and applied to the edge of the membrane from above and below and fastened with bolts, thereby clamping and fixing the edge of the membrane. It was hot.

(Problem to be solved by the invention) According to this conventional example, the fixed end of the roof membrane is bent and stretched around the attachment part of the flat plate, so that the flat plate and the membrane end come into contact with each other. However, if the membrane moves under the influence of wind or the like, the contact portion may wear out and be damaged over time, and there is still room for further improvement in ensuring stable attachment.

An object of the present invention is to provide a device for attaching a membrane end in a tension membrane structure that can stably support the fixing part of the membrane end without being damaged over time.

(Means for Solving the Problems) The present invention includes a hanging body, an angled mounting body, and a presser body. The above mounting body is
It is suspended and supported in a chevron shape by the hanging body, and the inclined upper surfaces on both sides of the chevron top are used as mounting surfaces for the membrane material. The holding body holds an end portion of the membrane material attached to the mounting surface of the mounting body with the mounting body.

(Function) The end of the roof membrane will be stretched along the inclination angle of the mounting surface.

(Example) Examples of the present invention will be described below with reference to the drawings.

First, the structure of the roof of a building with a tension membrane structure will be explained, and then the specific configuration of the present invention will be explained.

In Figures 4 to 6, the roof is a single-slope roof, and support frames 1 constituting the frame of the roof are arranged at predetermined intervals in the left-right direction in Figure 6, and a roof membrane 2 is stretched below the support frames. The area around the roof membrane is fixed to beams 3. A plurality of roof membrane hanging bodies 4 are suspended from each support frame 1 at predetermined pitches, and the roof membrane 2 is suspended from the lower mounting portions 41 (FIG. 1). The membrane tension of the roof membrane 2 is adjusted by a membrane tension adjusting body 5 provided on a hanging body 4. The roof membrane 2 is pressed down on its upper side by a hold-down cable 6 which is arranged between and along the support frames 1.

Now, the specific structure of the attachment part 41 in the hanging body 4 will be explained with reference to FIGS. 1 and 2.

Angled mounting body 42 with a predetermined length
are arranged continuously along the support frame 1. A support plate 43 is passed horizontally inside the top of each mounting body 42, the lower part of the hanging body 4 passes through the center of this support plate and the top of the mounting body, and the lower end is fixed with a nut 44. The mounting body is suspended in a chevron shape at the lower part of the hanging body 4. The support plate 43 is the mounting body 4
It also serves as reinforcement for 2. The upper surfaces of the mounting body 42, which are inclined downward from both sides of the chevron-shaped top, respectively, serve as mounting surfaces 421 and 422 for the roof membrane 2, and both mounting surfaces are sloped surfaces having the same angle.
Bolt insertion holes 423 are formed in the mounting surfaces 421 and 422 of the mounting body 42, and bolts 45 are raised from the inner surface through the bolt insertion holes above the mounting surfaces. The end of the roof membrane 2 is hooked to the bolt 45, and the end of the roof membrane 2 is held down by a holding plate 46 with the elastic plate 47 interposed between the mounting surfaces 421 and 422, and then fixed by tightening the nut 48. It has been done. The elastic plate 47 is arranged along the entire length of the membrane edge, and is attached to the attachment bodies 42 adjacent to each other in the longitudinal direction.
This seals the gaps and ensures watertightness. The outside of the top of the mounting body 42 is covered with a cover 49 to prevent water from leaking into the room from the outside of the mounting body. As the material of the cover 49, for example, a rubber sheet or the same material as the roof membrane is used.

Further, the membrane tension adjusting body 5 is composed of a turnbuckle having reverse threaded portions 51, 52 and a nut 53, as shown in FIG. Membrane tension adjustment body 5
By turning , the fixed position of the roof membrane 2 moves up and down, and the membrane tension is adjusted.

Another example of the present invention will be explained based on FIG.
a are provided at a predetermined pitch, and the holding parts 461a, 461a at the bottom of both sides are attached to the mounting surfaces 421, 4.
22. The ends of the roof membrane 2 are fixed on both mounting surfaces with a holding part 461a, bolts 45, and nuts 48. Further, the upper horizontal part of the presser body 46a is attached to the lower part of the hanging body 4 and fixed with a nut 44a.

47a is an elastic plate, and 49a is a cover.

The shape of the roof is not limited to the example shown in the fourth figure, and the membrane tension adjusting body is not limited to the turnbuckle type as in the above example.

(Effects of the invention) As described above, according to the invention, since the ends of the membrane are fixed and stretched with pressers along the mounting surfaces of the membrane material on the sloped upper surfaces on both sides of the chevron-shaped top of the mounting body, The fixing portion at the end of the membrane does not bend excessively, does not get damaged over time, and can be stably supported.
