Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-direction curved film roof which is preferably implemented as a large-area roof excellent in the beauty of shaping such as a gymnasium and a cultural center without pillars. The present invention relates to a bidirectional curved film roof having an improved joint structure between a keel laminated member erected in the center of the curved film roof, a cable net, and a surrounding frame.

[0002]

2. Description of the Related Art Conventionally, a film roof having a smooth positive / negative two-direction curvature made of a Teflon film or the like has been already widely known because of its many examples. A so-called cable net structure in which a hanging cable having almost no rigidity and a holding cable are stretched and combined in a mesh shape is also well known as a structure forming a positive / negative bidirectionally curved roof. Recently, a large-area two-direction curved membrane roof has been proposed in which a keel laminated lumber is erected in the center of the roof, and a cable net constructed around this is stretched with a membrane material (see Figs. 1 and 2). ..

[0003]

The cable net structure constructed by using the keel laminated wood at the center of the roof like the above-mentioned large-area two-direction curved film roof has a good-looking and light membrane roof. Will be realized. However, unless the keel laminated member and the cable net and the cable net and the peripheral frame are structurally firmly and firmly fixed, it is not possible to provide a stable bidirectional curved membrane roof.

Therefore, an object of the present invention is to solve the problem that a cable net and a keel laminated member, a cable net and a peripheral frame are a work piece in a two-direction curved membrane roof using a cable net and a keel laminated member. It is an object of the present invention to provide a large-area two-direction curved membrane roof having a stable structure, which can be easily and securely joined by a reliable means, and yet can smoothly transfer the load of the cable net to the keel laminated member and the surrounding frame.

[0005]

As a means for solving the above-mentioned problems of the prior art, a large-area two-direction curved membrane roof according to the present invention has a suspension cable 2 and a presser foot as shown in the drawings. A cable net 9 having a curvature in two directions is formed with the cable 3, and a film material 6 is formed on the cable net 9.
In a two-direction curved membrane roof in which a keel laminated member 1 having a truss structure is erected in an arch shape in the same direction as the presser cable 3 is hung on the keel beam 11 of the keel laminated member 1. A through hole 4 that is inclined in the extension line direction at one end of the cable 2 is provided, and a reaction force receiver 5 that is perpendicular to the suspension cable 2 is provided at the inner end portion of the through hole 4, and the suspension that passes through the through hole 4 is suspended. A screw end sleeve 7 at the end of the cable 2 is fastened to the reaction force receiver 5 with a nut 8, and the screw end sleeve 7 at the other end of the hanging cable 2 turns an anchor member 10 attached to a peripheral frame 15. It is characterized by being connected by a buckle 12.

[0006]

Since the through hole 4 inclined in the extension line direction at one end of the suspension cable 2 is provided in the keel beam 11, and the reaction force receiver 5 perpendicular to the suspension cable 2 is provided at the inner end portion of the through hole 4.
The end portion (screw end sleeve 7) of the suspension cable 2 passed through the through hole 4 is easily fastened with a nut 8 on the reaction force receiver 5, and the cable net 9 and the keel laminated member 1 are firmly coupled. (Fig. 3). Therefore, the deformation of the cable net 9 is absorbed by the keel laminated member 1, and at the same time, the load of the cable net 9 is smoothly transmitted to the keel laminated member 1.

The screw end sleeve 7 at the other end of the suspension cable 2 is easily and firmly connected to the anchor member 10 attached to the peripheral frame 15 by the turnbuckle 12 (FIG. 6, FIG.
7). Therefore, the cable net 9 and the keel laminated member 1, and the cable net 9 and the peripheral frame 15 are firmly joined to each other, and a large-area two-direction curved film roof having a stable structure is realized.

EXAMPLES Next, examples of the present invention shown in FIGS. 1 to 7 will be described. Figure 1 shows a plan view of a bi-directionally curved membrane roof,
A film material 6 is stretched on a cable net 9 formed by the suspension cable 2 and the presser cable 3 and having a bidirectional curvature. At the center of the roof, a keel laminated member 1 having a truss structure is erected in an arch shape in the same direction as the presser cable 3 (see FIGS. 2 and 3).

The suspension cable 2 is a cable having an outer diameter of about 34 mm, and is arranged substantially symmetrically on both sides of the keel laminated member 1 with respect to the keel laminated member 1 at a pitch of about 4 m in parallel. Screw end sleeves 7 are attached to both ends of the suspension cable 2, respectively. Presser cable 3
Is a cable having an outer diameter of about 40 mm, which is arranged substantially orthogonal to the hanging cable 2 and is arranged substantially parallel to the upper side of the hanging cable 2 so that a cable net 9 having a desired curvature (curved surface) is formed. ing. A film material 6 such as a glass fiber film having a thickness of about 0.6 mm is stretched on the cable net 9.

The keel laminated material 1 has a large-diameter dome shape with a total length of about 60 m, and is formed in a truss structure composed of the keel beams 11, 11 facing each other and a connecting material 17 connecting them. As shown in FIG. 2, the keel laminated material 1 is erected on a concrete leg 19 constructed on a concrete foundation 18 constructed on the ground. 4 and 5 show a suspension cable 2 and a keel laminated member 1 (keel beam 1).
It shows the state of joining with 1). The keel beam 11 of the keel laminated member 1 has through holes 4 inclined in the extension line direction at one end of the suspension cable 2 at a pitch of about 4 m like the suspension cable 2 ... Is provided.

The inner end of the through hole 4, that is, the keel beam 1
A reaction force receiver 5 is provided on the inner surface of 1. The reaction force receiving body 5 includes a reaction force receiving body 5a arranged at a right angle to the extension line direction of one end of the suspension cable 2, and the reaction force receiving body 5a.
Support plate 5 welded to and joined to the inner surface of the keel beam 11
b, both of which are formed with small holes 51, 52 having a size through which the screw end sleeve 7 at the end of the suspension cable 2 passes.

Therefore, when the screw end sleeve 7 at the end of the suspension cable 2 is passed through the through hole 4 of the keel beam 11 and pushed in as it is, the small holes 52, 51 of the reaction force receiver 5 formed in the extension line direction thereof. Go through smoothly in order. Then, the suspension cable 2 is firmly coupled to the keel laminated member 1 by screwing and fastening the end portion of the screw end sleeve 7 protruding from the small hole 51 of the reaction force receiver 5 (main body 5a) with the nut 8. Therefore, the deformation of the cable net 9 is absorbed by the keel laminated member 1 through the suspension cable 2. The load of the cable net 9 is smoothly transmitted to the keel laminated member 1.

6 and 7 show a state in which the suspension cable 2 and the peripheral frame 15 are joined by the turnbuckle 12. The anchor member 10 is attached to the peripheral body 15. The anchor member 10 is an anchor plate 23.
And an anchor end 22 attached to the anchor plate 23 and a fork bolt 19. The anchor plate 23 is fixed to the peripheral frame 15 by anchor bolts 16. The anchor end 22 attached to the anchor plate 23 and the fork bolt 19 are connected by a pin 21.

Therefore, the end of the threaded end sleeve 7 at the end of the suspension cable 2 and the end of the fork bolt 19 of the anchor member 10 are screwed into both ends of the turnbuckle 12 to adjust the tension, The lock nut 20 is tightened to firmly connect the two. Therefore, the cable net 9 and the keel laminated member 1, and the cable net 9 and the peripheral frame 15 are firmly joined while adjusting the tension, so that a large-area two-direction curved film roof with a stable structure can be easily and reliably realized. To be done.
