DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable net membrane structure used for connecting a membrane material and a cable by supporting the membrane material higher than the cable when constructing a membrane roof having a cable net membrane structure. Regarding connecting hardware.

[0002]

In order to provide a large-area membrane roof having a smooth two-way curvature in conformity with the curved surface of a cable net formed by a suspension cable and a holding cable, the applicant has proposed a large-area two-way curvature membrane. The invention of the roof was proposed earlier (Japanese Patent Application Hei 4-
No. 17905). As shown in FIG. 4, the membrane roof has a trussed structure erected in the center of the roof, and one end of a suspension cable b is fixed to both sides of an arch-shaped keel glulam a in a symmetrical arrangement, and the other end is It is fixed to the peripheral frame d. A holding cable (not shown) is arranged above the suspension cable c. The film material c is supported at a certain height above the suspension cable b by the connecting hardware A (not shown), a film surface is formed on the upper surface of the cable net, and a moderate amount of tension is applied to the film material c. Has been introduced.

[0005] As shown in FIG. 5 in detail, the connecting hardware A has a Y-shaped shape in which both outer sides of a pair of flat bars g, g at a joint portion between the membrane materials c are clamped by bolts h. A clamp n and a split clamp j holding the outer periphery of the suspension cable b are bolted to both ends of a support plate m having a required length. Y-shaped clamp n
And the end of the support plate m are firmly fastened with two bolts p, p.
It is fastened by the bolts k, k.

[0004]

In order to form a smooth curved membrane surface and realize a good-looking membrane roof structure, the membrane material c is supported above the cable b at an appropriate height and stretched. It is reasonable to set up. However, the positional condition of the hanging cable b on which the connecting hardware is supported is actually a construction error regardless of the design, so that the film is set at a certain height based on the position of the hanging cable b. Simply by placing the material c, the film material c cannot be formed into a clean curved surface as a whole. In short, the connecting hardware is required to have an adjustment function capable of correcting a construction error in the position of the suspension cable b. In this regard, since the conventional connecting metal A of FIG. 5 uses a support plate m of a fixed shape and is merely a configuration in which the respective members are connected by bolting, the dimensions cannot be adjusted in the horizontal and vertical directions. For this reason, it cannot be changed and used according to various conditions, and as a result, there is a disadvantage that the film material c cannot be formed on a smooth curved surface. Further, since the connecting hardware A has a large number of parts, and it is troublesome to manage and use the parts, further simplification is expected.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to further improve the connecting hardware previously proposed by the applicant, adjust to the desired length and direction in response to various conditions such as a change in the installation state of the cable and construction errors. Excellent flexibility and versatility that can be changed, the membrane surface can be finally formed on a clean curved surface, and the number of parts is reduced as much as possible to make the structure easy to work, thereby reducing the construction cost and improving the work efficiency of installing the membrane material. An object of the present invention is to provide a connecting hardware in a cable net membrane structure.

[0006]

As a means for solving the above-mentioned problems of the prior art, a tie in a cable net membrane structure according to the present invention is provided with a membrane member 7 as shown in the embodiment in the drawings. The lower end 1a of the upper connection frame 1 having the U-shaped receptacle 5 is rotatably pin-connected to one of the bolts 2a of the turnbuckle 2 to hold the cable 6 therebetween.
An upper end portion 3a of the cable clamp 3 having a shape is rotatably pin-connected to the other bolt 2a 'of the turnbuckle 2.

[0007]

By rotating the sleeve of the turnbuckle 2, the connecting piece can be finely adjusted to a desired length as appropriate, so that the film material 7 can be accurately stretched from the cable 6 to a desired height position, and can be smoothened. A curved film surface can be formed neatly. Since the upper connection frame 1 and the cable clamp 3 are rotatably pin-connected to the bolts 2a and 2a 'of the turn buckle 2, respectively, the flexible connection in a form corresponding to the installation location of the connecting hardware is possible. It is.

In particular, the upper connecting frame 1 and the cable clamp 3
Since the structure is simplified and the number of parts is small, the work efficiency on site is improved.

[0009]

Next, an embodiment of the present invention shown in FIGS. 1 to 3 will be described. FIG. 1 shows the entire configuration of the connecting hardware. The connecting metal supports the membrane material 7 at a certain height above the suspension cable 6 of the two-way curvature membrane roof having the cable net membrane structure as shown in FIG. 4 (see FIG. 3), and a curved membrane surface is formed. Have been.

The connecting hardware has an upper connecting frame 1, a turnbuckle 2, and a cable clamp 3 as a basic structure. The upper connecting frame 1 is mostly constituted by a U-shaped receptacle 5 with a through hole 17 to which the membrane material 7 is attached (FIG. 1).
A), its lower end 1a is rotatably connected to a bolt 2a (e.g., eye bolt or lot bolt) on the upper side of the turnbuckle 2 in a pin shape by a hard lock nut 8. FIG. 2 shows how to attach the membrane 7. Each of the two membrane members 7, 7 is wound around a rope 11 at each end thereof, and the rope is disposed along a joint portion of the membrane members 7, 7, and the flat bars 12, 12 form the membrane members 7, 7. An end is clamped, and the rope 11 is brought into contact with the lower edges of the flat bars 12, 12. The flat bars 12, 12 and U
The bolt 13 is inserted through the through hole 17 of the U-shaped socket 5 with the filler plates 15 and 15 interposed between the U-shaped socket 5 and
It is firmly fastened with a hard lock nut 14. The film material 10 on the upper surface is a rain seal.

As shown in FIG. 1B, the lower part of the cable clamp 3 is formed in a C shape capable of holding a cable 6 such as a suspension cable, and then the upper end part 3a extending upward like an arm. Is formed. The upper end 3a is also rotatably connected to a pin in the form of a pin by the other bolt 2a 'below the turnbuckle 2 and a hard lock nut 8.

Therefore, by simply turning the turnbuckle 2, the connecting metal can be finely changed to a desired length as appropriate, and an appropriate length for each value of the cable 6 whose position is variously shifted due to various conditions such as construction errors. You can set up the connection hardware,
By stretching the film material 7 at a desired height position, a smooth curved film surface can be formed neatly. In addition, upper connecting frame 1
And the cable clamp 3 are rotatably connected to the bolts 2a and 2a 'of the turnbuckle 2 in the form of pins, so that the upper connection frame 1 and the cable clamp 3 are appropriately rotated according to the installation location of the connection hardware. Flexible use is possible. For example, even when a tie is installed near the keel glued laminated lumber 9 shown in FIG. 3, the cable clamp 3 can be freely rotated and installed on the cable 6 as desired, and has workability. In addition, since the upper connection frame 1 and the cable clamp 3 are configured to be extremely simplified, installation work on site is extremely easy.

[0013]

[Effects of the present invention] According to the tie in the cable net membrane structure according to the present invention, the tie can be suitably adjusted and changed to a desired length and direction, so that it can be smoothly and visually matched with a desired curve. A cable net membrane roof structure having a good membrane surface can be realized. In addition, since the number of parts is reduced as much as possible and the structure is simplified, the construction cost can be reduced, and the work at high places can be performed safely, and the installation efficiency of the membrane material can be improved.
