DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a membrane material for a membrane structure,
More specifically, the present invention relates to a film material on which a cable used for forming a film structure having a desired shape and reinforcing the material can be favorably arranged.

[0002]

2. Description of the Related Art This kind of membrane structure is formed by stretching a membrane material on an installed main cable. In the case of a relatively large membrane structure, the membrane structure is formed into a desired shape. In some cases, other cables may be appropriately disposed between the main cables in order to perform reinforcement and the like.

In this case, conventionally, as shown in FIG. 6, for example, both ends of a band-shaped cover 9 are welded along the back surface of the membrane main body 1a, and the cable 5a is inserted into the cover 9 or the like.
As shown in FIG.
Is welded along the back surface of the membrane main body 1a, and both side pieces of the hanging cloth 10 are welded.
10a so as to wrap the cable 5a,
A racking rope 12 is inserted into and attached to the eyelets 11, and the end is fixed.
And fixed the cable 5a.

[0004]

However, in the former case, for example, when an external force or the like is applied to the membrane main body 1a,
Since the cable 5a moves in the space A formed between the membrane main body 1a and the cover 9, there is a disadvantage that the appearance of the membrane structure is deformed, and the cover 9 is detached from the membrane main body 1a. There was a great problem that the cable 5a could be exposed outside.

The joint 1b between the cover 9 and the membrane main body 1a has a double structure. However, if a part of the membrane main body 1a is carelessly cut, it is difficult to prevent so-called tear propagation by itself. Therefore, there is also a problem that the membrane main body 1a is largely torn.

On the other hand, in the latter case, the cable 5a
Movement can be prevented, but there is no guarantee against tear propagation like the former, and the racking rope 12
Is troublesome, so that a series of on-site work becomes very complicated, resulting in inconvenience of lack of workability.In addition, there are various problems that the appearance and appearance are poor. It was.

SUMMARY OF THE INVENTION Therefore, the present invention has been made to solve the above-mentioned conventional problems. By preventing the cable from moving, the appearance of the membrane structure can be maintained, and the tear propagation can be maintained. It is an object to prevent the occurrence of the problem.

[0008]

In other words, in order to solve the above-mentioned problems, the present invention extends between main cables 8.

It is to become.

[0009]

Therefore, in the film material characterized by the above-mentioned structure, the cylindrical member 2 is displaced in the axial direction of the cable 5 with a predetermined interval in a direction intersecting the axial direction. Since the cable 5 is provided in the main body 1, the lateral movement of the cable 5 inserted into the tubular body 2 is regulated by the pair of tubular bodies 2. Therefore, a sufficient supplement by the cable 5
High strength can be expected, and deformation of the film main body 1 is extremely unlikely to occur. Further
In addition, since the overlapping portion 4 has a double structure, the overlapping portion of the cylindrical body 2

[0011]

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Will be explained. 1 and 2, reference numeral 1 denotes a fluororesin membrane main body formed in a desired shape, which is stretched over a main cable 8 stretched.

2, a square hole 2a is formed at a predetermined interval in a sheet material of the same material as the membrane main body 1 as shown in FIG. A pair of tubular bodies formed at the same time and the belt-like parts 2b at both ends thereof are welded to form a double-structured overlapping part 4, and the tubular part 3 of the tubular body 2 on one side is replaced by the tubular body on the other side. In order to dispose the tubular members 2 with a gap 6 between the two overlapping portions 4, the respective cylindrical portions 2 are arranged at predetermined intervals on the back surface of the membrane main body 1 so as to be displaced in the longitudinal direction. It is attached by welding.

The membrane material according to the present embodiment has the above-described configuration, and one cable 5 is inserted into the cylindrical portion 3 of each of the cylindrical bodies 2. The cable 5 is configured so as to be located on the inner end side of each tubular portion 3 as shown in FIG. 4, and the cable 5 is connected to the main cable 8 via a connection fitting 7.

Since the cable 5 receives a pulling force left and right by the tubular portions 3 of the tubular members 2 and is restricted from moving laterally, even if the cable 5 is inadvertently applied to the membrane body 1 or the like, Is added, the stored state of the cable 5 is maintained well, and the appearance of the membrane structure is not deformed.

[0015] Further, since the welded portion of the overlapped portion 4 of the tubular body 2 has a triple structure including the film main body 1, the so-called tear propagation can be well prevented in a portion to which so-called tear propagation is applied. Deformation and breakage of the main body 1 can be minimized.

Further, at the portion of the film main body 1 where the gap 6 is located, light is radiated from the outside only through the film main body 1, and the amount of transmitted light depends on the overlapping portion 4 and the cylindrical portion 3. Is larger than the portion where is located, a beautiful checkered pattern appears on the ceiling surface, so that the aesthetic appearance of the seed film structure is not impaired, and the cable 5 can be suitably processed.

Further, since the film material according to this embodiment has a very simple structure as a whole, there is an advantage that it can be manufactured easily and at low cost.

In the above-described embodiment, the cylindrical body 2 having the plurality of cylindrical portions 3 is used, but the specific number is not limited, and it depends on the length of the cable 5 and the like. Can be changed. In short, at least a pair of cylindrical bodies 2 may be displaced in the axial direction of the cable 5 with respect to each other and provided on the back surface of the membrane main body 1 at a predetermined interval in a direction intersecting the axial direction.

The cylindrical body 2 is formed by joining the ends of one sheet material in a superposed state, and joining the superposed portion to the membrane main body 1 by welding or the like .
It may be attached and installed.

Further, in the above embodiment, the gap 6 is formed relatively wide, but the specific dimensions such as the width S and the length L do not matter. For example, as shown in FIG. It is also possible to change the pattern in which the ceiling surface appears as required.

In addition, the specific structure of each part of the membrane structure according to the present invention can be arbitrarily changed within the range intended by the present invention.

[0022]

As described above, according to the present invention, the cylindrical body is provided on the back surface of the membrane main body at a predetermined distance in the direction intersecting with the axial direction of the cable. As a result, the cable is inadvertently moved to cause deformation of the membrane main body, or the cover is attached to the membrane main body as in the conventional case where the cable is simply housed in a belt-shaped cover attached to the membrane main body. It is no longer possible to separate the cable from the outside and the cable is exposed to the outside, so that the movement of the cable is effectively controlled by the pair of cylindrical bodies, and a special effect is obtained.

Further, since the double-structured overlapping portion provided on the tubular body is attached to the membrane main body, so-called tear propagation can be prevented at the portion, so that damage to the membrane material is prevented. The unique effect that it can be minimized is obtained. According to the second aspect of the present invention, the one cylindrical portion is
Between the tip and the overlapping part of the other cylindrical body facing it
Since there is a gap, the location of the gap and the location where the tubular body is located
Light and darkness due to the difference in the amount of transmitted light occurs,
A beautiful checkered pattern appears in the area reinforced by the lures.
When such a pattern appears, the casing of this kind of membrane structure
Make up for the rough scenery of the part reinforced by the bull, it is beautiful
Has the secondary effect of being able to create
I do.

Further, since the film material according to the present invention has a very simple overall structure, there is also a practical effect that it can be manufactured easily and at low cost.
