Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tension membrane structure that can be used in sports facilities such as swimming pools and gymnasiums, shopping facilities, exhibition halls, and the like.

(Prior art) A conventional tension membrane structure involves assembling a frame as a framework, stretching a roof membrane above the frame, supporting the roof membrane with supports on the frame, and introducing tension around the membrane. , there are things that make adjustments.

(Problems to be Solved by the Invention) According to this conventional example, since the frame supporting the membrane is located below the roof membrane, this frame is completely exposed to the indoor space, which does not take advantage of the membrane structure. When applied to a swimming pool, for example, the frame rusts and maintenance is troublesome, and it is difficult to reintroduce and adjust the tension around the membrane.

The purpose of the invention is to keep open spaces and more! l! The object of the present invention is to provide a tension membrane structure that facilitates tension introduction and fill adjustment while ensuring the advantages of 4M construction.

(Means for Solving the Problems) In the present invention, a roof membrane 2 is stretched below a support frame 1, and a plurality of hanging suspensions 4 are suspended from the frame at a predetermined pitch, and are attached to the support frame. The hanging bodies arranged in parallel along the roof membrane 2 are attached at portions 41 and 42 to suspend the roof membrane 2, and each hanging body is provided with a tension adjusting body 5 for introducing and adjusting the tension of the roof membrane. There is.

(Function) The support frame 1 cannot be directly seen from the indoor side due to the roof membrane 2. Further, the tension of the roof membrane 2 is introduced and adjusted by operating the adjusting bodies 5 of the hanging bodies 4, respectively.

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

In Figures 1 to 3, the roof of the building with a tensile membrane structure is a single-sided roof, and the support frame 1 that constitutes the roof frame.
are arranged at predetermined intervals in the left-right direction in Figure 3, and a roof membrane 2 is stretched below the support frame, and the area around this membrane is P! ? ,
It is fixed at 3. A plurality of roof membrane suspension bodies 4 are suspended from each support frame 1 at a predetermined pitch, and the roof membrane 2 is suspended at the lower part 41 (FIG. 4). The tension of the roof membrane 2 is adjusted by a membrane tension adjustment body 5 provided on the hanging body 4. The roof membrane 2 is pressed downward on its upper side by a hold-down cable 6 arranged between and along the support frames 1.

Here, the specific structure of the attachment part 41 in the hanging body 4 will be explained with reference to FIGS. 4 and 5.

The pair of presser plates 411, 411 face each other, their lower portions are curved outward, each is formed to a predetermined length, and is continuously disposed along the support frame 1. . 6. Support plates 412 are fixed to the holding plate 411 by welding at a predetermined pitch so as to be perpendicular to the outer surface.
Each support plate also serves as reinforcement for the presser plate. Each support plate 412
For mounting, a hole 412a is opened, and the presser plate 411 is suspended by the bifurcated lower leg portion 4a of the hanging body 4 through this hole. On the inside of both presser plates 411, the ends of the roof membrane 2 are held together in close contact with each other via elastic plates 413, 413. The opposing holding plates 411 are mounted in opposite positions through holes 411a, and bolts 414 are passed through the holes to fixedly connect both holding plates together with nuts 415, and at the same time, the membrane ends is fixed to the presser plate.

The elastic plate 413 is disposed over the entire length of the membrane end.
Watertightness is ensured by sealing gaps between longitudinally adjacent presser plates. Further, in order to prevent water from leaking into the room from above between the holding plates 411, a cover 416 made of the same material as the roof membrane 2 or made of a rubber sheet covers the gap above the holding plates.

Further, the membrane tension adjusting body 5 has a reverse threaded portion 5 as shown in FIG.
1.52 and a turnbuckle with a nut 53. By turning this adjustment body 5, the end of the roof membrane 2 moves up and down, and the tension is adjusted.

Another example of the mounting section on the hanging body 4 will be explained with reference to FIG. 6.

In this example, the mounting part 42 is an angular mounting part 42 with a predetermined length.
2 in a horizontal state, the lower part 4a of the hanging body is attached to this support plate, and the hardware 421 is hung thereupon. The installation is done with bolts 424, 424 on both sides of the hardware 421 from the bottom.
The ends of the membrane are hooked onto these bolts, the ends of the membrane are held down by presser plates 427 and 427 via elastic plates 423 and 423, and fixed with nuts 425 and 425.

426 is a cover that covers the top of the hardware 421.

According to the example of the part 41 shown in FIG. 4, the mounting shown in FIG. 4 is preferable from the viewpoint of rust prevention since not only the support frame 1 but also the mounting part is not exposed indoors, so that an open space in the room can be better secured.

Note that the shape of the roof is not limited to the example shown in the first figure, and the tension adjusting body is not limited to the turnbuckle type as shown above.

(Effects of the Invention) As described above, according to the present invention, the support frame is not exposed indoors, so the open space, which is an advantage of the membrane structure, is not impaired, and when applied to a swimming pool, for example, the frame There is no problem with rust, and since a tension adjustment body is provided on the hanging body, it is easy to reintroduce and adjust the tension.
