DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for fixing an end portion of a film material to a base for fixing the film material.

[0002]

2. Description of the Related Art Recently, a membrane material has been widely used as a building material due to a high degree of freedom in formation. One of the problems in using the film material as a building material is how to fix the film material to a foundation which is a pillar or a beam for fixing the film material.

Conventionally, for example, a rope as a core material is sewn on the edge portion of a membrane material, and then placed on a base body, and then tension is applied to the membrane material. A method of fixing a membrane material to a foundation in a sandwich state by placing a holding plate along the material and bolting the holding plate and the base body holding the membrane material at a plurality of places is used. . Although the fixing strength between the membrane material and the base body by this method is sufficient, it is necessary to tow in multiple places to draw the membrane material in parallel to the base body, or use a large membrane material In such a case, the number of times of bolting increases, so that the work tends to be complicated.

The following technique is also used from the viewpoint of facilitating the work of fixing the edge of the film material.
That is, the edge of the membrane material to which a core material such as a rope is attached by sewing or the like is formed into a long guide groove having a hollow guide groove in which a slit for taking out the membrane material is opened in the length direction. The edge of the membrane material is hooked on the fixing tool by inserting it into the base material, and the fixing tool is retracted backward to apply tension to the membrane material and fix the fixing tool to the base body in that state to fix the membrane material to the base. The technique of fixing to the body is used. If such a fixing tool is used, it is not necessary to pull the film material in a large number of parts, so that the burden in performing the film material fixing operation is reduced. In particular, a fixing block having a substantially T-shaped cross section in which a head portion of a bolt can be inserted and a bolt hole through which a screw portion of the bolt penetrates is provided on the back side of the fixing tool. In the case where a technique is used in which a fixing tool is drawn to the fixed block side by inserting a head into the bolt hole and screwing a bolt through the bolt hole with a nut from the back side of the fixed block. In this case, the advantage is obtained that not only the work of pulling in the fixing tool is easy but also the fixing of the film body can be performed as it is, so that the work load can be reduced.

However, this technique is not without improvement. In this technology, a plurality of fixing blocks are required to secure the mounting strength of the membrane material, but not only the work of tightening nuts by the number of fixing blocks is complicated, but also many fixing blocks are mounted on the base body. The operation itself is troublesome, and the fixing block remaining after the operation may result in a bad influence on the aesthetic appearance of the film body attaching portion.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention can secure sufficient fixing strength for use as a building material, can perform construction at a low cost by an easier operation, and can perform fixing after completion. The purpose of the present invention is to provide a membrane fixing technique that is excellent in aesthetics of a part.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the applicant of the present invention has made it possible to hook the edge of a membrane material having a core material attached to the front surface thereof and to fix a base material for fixing the membrane material. It is possible to fix to the membrane material edge part which is used to fix the membrane material edge to the base body while applying tension by pulling it from the back with the membrane material hooked Further research based on the technology of fixing the membrane material and the base body, and finding that the above problem can be solved by separating the part used for retraction in the fixing tool and the part making the fixation to the base body And arrived at the following invention.

The fixing device for the edge portion of the membrane used in the present invention is based on the above-mentioned fixing device, and is formed as a hollow for inserting a core material and has a slit for taking out the membrane material in a longitudinal direction. A guide hole is provided on the front surface thereof, and a connecting means capable of connecting with a retracting tool used for retraction is provided on the rear surface thereof. A locking means for fixing the base member to the base body is provided on the lower front surface thereof.

[0009] The fixing method of the edge of the membrane material using the fixing device is such that the core material attached to the edge of the membrane material by sewing or welding is inserted into the guide hole while the membrane material comes out of the slit. And the connecting means connected to the retracting tool is pulled backward, and the locking groove is moved to the back of the locking member to apply tension to the film material, thereby reducing the drawing force against the tension of the film material. By engaging the latching means with the latching member by releasing, the membrane edge is fixed to the base body, and the retracting device is removed from the coupling means.

According to this method, after performing a conventional operation of inserting the core material attached to the edge of the membrane material into the guide hole provided on the front surface of the fixing device, the connection provided on the back surface of the fixing device. Only by performing the operation of retracting the means with the retracting tool and releasing the retracting force of the retracting means, it is possible to fix the edge portion of the film material in one shot, so that the working efficiency is remarkably improved. Further, in the fixing device used in this method, the connecting means and the continuous retraction means can be connected and released freely. Therefore, according to the fixing method of the film material according to the present invention, in the final stage of the fixing operation of the film material, by removing the retracting means that may affect the aesthetic appearance of the film material fixing portion, the design is also excellent. Can be obtained. Here, it is preferable that the hooking means provided on the fixing device and the hooking member provided on the base body have a shape that fits each other from the viewpoint of ensuring the fixation. For example, the hooking member may be a hooking piece projecting behind the base body, and the hooking means may be a hooking groove that fits into the hooking piece, or the hooking member may be an opening groove behind the base body. It is possible that the locking means is a convex member that fits into the groove. Incidentally, the locking groove provided on the front surface of the fixing device according to the present invention,
Although it may correspond to a part of the film material edge, by making this extend over the entire length of the film material edge,
This is preferable because a secure fixation over the entire length range can be obtained, instead of a partial fixation such as bolting.

Preferably, the connecting means is a connecting groove having a substantially T-shaped cross section provided on the back surface over the length direction and opened at a portion of the T-shaped leg. The fixing device provided with such a connecting means also has the same basic use method, but a retracting member composed of two retracting members formed by bending a plate material into an approximately L-shape and perforating a small hole in one piece. The following uses can be performed in combination with the tool. That is, when the connecting means including such a connecting groove and the retracting tool are used, when the connecting means and the retracting tool are connected, the other piece of the retracting member is formed by a T-shaped arm portion in the connecting groove. The connecting groove and the retracting tool can be connected by forming the retracting tool having a substantially T-shaped cross-section by superimposing the one pieces back to back to form a retracting tool having a substantially T-shaped cross section. At the same time, when removing the retracting tool from the connecting tool, it is possible to pull out the retracting tool divided into the two retracting members from the opening of the connecting groove by shifting along the connecting groove.
Therefore, in this way, when connecting and releasing between the connecting means and the retraction tool, it is possible to save the trouble of moving the retraction tool over a long distance in the connection groove to a predetermined place where the retraction is desired. Thus, the efficiency of the work can be further improved. In this case, the retraction work in this case can be performed by hooking the towing hook so as to penetrate the two matching small holes in the retraction tool formed by combining the two retraction members, and towing the hook. This is convenient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, first to third embodiments of a method for fixing an edge portion of a film material according to the present invention will be described with reference to FIGS. Note that portions common to the embodiments are denoted by common reference numerals, and redundant description is omitted.

[0013] First Embodiment: FIG. 1 is a fixing method of the membrane material 10 edge portion according to the first embodiment of the present invention is a perspective view schematically showing. In this embodiment, the edge of the membrane material 10 to which the rope 11 serving as the core material is attached by sewing is attached to the edge of the membrane material 1.
It is to be fixed to the pipe 20 as a fixing base body, and at that time, a film material fixing tool 30 and a plate body 40 as a hooking member are interposed between the film material 10 and the pipe 20.

The film material fixing tool 30 is made of aluminum, and has a guide hole 31 and a retaining groove 32 on a front surface thereof and a connecting means 33 on a rear surface thereof. The guide hole 31 allows the rope 11 attached to the edge of the film material 10 to be inserted, and is provided in the length direction of the fixing tool 30. In addition, a slit 34 that allows the film material 10 to be taken out is provided on the front surface thereof along the length direction of the guide hole 31. The engaging groove 32 has a shape substantially corresponding to the shape of the back surface portion of the plate body 40.

The edge and the guide hole 31 of the fixing tool 30 are fixed. Specifically, the rope 11 is inserted into the guide hole 31 while the film material 10 comes out of the slit 34 so that the edge of the film material 10 is hooked on the guide hole 31. Since the rope 11 is thicker than at least the interval between the slits, the rope 11 functions as a stopper for the slit 34 so that the edge of the film material 10 does not fall out of the guide hole 31. As will be understood from this, the core material 11 may be of any thickness as long as it can function as the stopper, and does not necessarily need to be constituted by a rope.

After the edge of the film material 10 and the fixing tool 30 are hooked, the fixing tool 30 is pulled in through the drawing tool 50 connected to the connection groove 33. Here the retractor 5
Reference numeral 0, as shown in FIG. 3, comprises two retraction members 51 formed by bending a metal plate material into an approximately L-shape and forming a small hole 52 in one of the pieces. The retraction tool 50 is connected to the connection groove 33 by inserting the other piece of the retraction member 51 into the connection groove 33 such that the other piece of the retraction member 51 fits into the T-shaped arm portion of the connection groove 33, and putting the one piece back to back. This is performed by forming the retraction tool 50 having a substantially T-shaped cross section into a T-shape as shown in FIG. Since the small holes 52 are arranged so as to coincide with each other to form a through hole when the one piece is superimposed, a hole convenient for towing is provided in the retracted tool 50 in the connected state. Will exist. A hook 53 is engaged with the small hole 52 as shown in FIG.
Is drawn in the rear direction by a drawing device not shown. As a result, the fixing tool 30 is retracted in the rear direction.

When the fixing tool 30 is pulled in, the locking groove 32 provided on the front surface thereof is moved to the back of the plate body 40 previously attached to the pipe 20. When sufficient tension is applied to the film material, the output of the wire drawing device is adjusted. By releasing the retraction force against the tension of the film material 10 by, for example,
2 is engaged with the plate body 40. At this time, since the plate 40 and the wedge 35 interfere with each other, the plate 40 is
However, the wedge 35 is plastically deformed by hitting the fixing device 30 from behind with a mallet or the like, so that the locking groove 32 and the plate body 40 are sufficiently fixed. Then, the retracting tool 50 fitted in the connecting groove 33 is shifted to each other along the connecting groove 33 so as to be divided into two retracting members 51, and then pulled out from the opening of the connecting groove 33 to be removed. The fixing work for the pipe 20 is terminated.

FIG. 4 shows a fixing structure of the pipe 20 and the edge of the film material 10 obtained by this method.

Second Embodiment FIG. 5 shows another example of a structure for fixing the edge of the film material 10 obtained by the method for fixing the edge of the film material 10 according to the present invention. The fixing device 30 used in the method according to this embodiment is the same as that in the first embodiment, except that the base member 2 on which the membrane material 10 is fixed.
Reference numeral 0 is different from the first embodiment in that the hook member 40 is formed integrally with the base body 20.

In the above description of the first and second embodiments, a locking member such as a plate is protruded from the locking member 40 on the base body 20 side, and the locking groove 32 to be fitted thereto is fixed. Although the example provided on the device 30 is shown, on the contrary, the base body 20 is provided.
The same effect can be obtained by providing a locking groove in the locking member 40 on the side and providing a locking piece that fits with the locking groove in the fixing device 30.
