Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure for suspending a film material with an edge rope between various structural supports such as a beam pipe or a column pipe.

[0002]

2. Description of the Related Art Conventionally, in various membrane structures, a membrane material used as a roof material, a ceiling membrane, an inner curtain or a side wall membrane is fixed to a support such as a beam / column pipe, a steel material or a frame. Various fixing structures have been adopted. Figure 6
In the fixing structure according to the first conventional example shown in FIG. 1, the film material 56 to which the edge rope is attached is drawn into the upper surface of the support material 50, and the waterproof rubber sheets 52 and 52 are provided on the front and back surfaces at the inner side position of the edge rope 51, respectively. Intervene,
A fixing plate 53 having a bolt through hole formed on the upper surface thereof is provided, and these supporting members 50 and waterproof rubber sheets 52, 52 are provided.
The fixing nut 56 is fastened to the fixing bolt 54 which is inserted through the fixing plate 53 and the fixing plate 53.
Is an example in which is fixed to the support material 50.

Next, the fixing structure according to the second conventional example shown in FIG. 7 is provided with an edge rope swallow portion 60a on the front side and a pull-in jig pocket groove 60b on the rear side.
And an aluminum fastener 60 that integrally extends from the main body and has an engaging groove 60c is brought in, and the film material 56 is provided on the edge rope swage portion 60a of the aluminum fastener 60.
After inserting and supporting the edge rope portion 51 of the above, as shown in FIG. 8, the pull-in jig 61 is temporarily fitted in the pull-in jig pocket groove 60b, and the pull-in jig 61 is inserted into the pull-in jig 61. The aluminum fastener 60 is pulled together with the film material 56 by the connected pulling means (not shown), and the engaging groove 60c of the aluminum fastener 60 is fitted into the hooking piece 62a formed on the structural support member 62 to be fixed. This is an example of doing so.

[0004]

The fixing structure according to the first conventional example is the fixing structure most commonly used in the past, but the number of parts per fixing portion is large and material management is complicated. In addition, there is a problem in that bolt fixing work must be performed at various places while maintaining the retracted state of the film material, which requires much labor and time for the fixing work. Further, there is a problem that it is difficult to uniformly apply tension to the film material 56.

On the other hand, the fixing structure according to the second conventional example is advantageous in that the film fastener 56 can be easily fixed by utilizing the aluminum fastener 60, and the tension introduced into the film member 56 can be made uniform. However, in order to fit the aluminum fastener 60 to the hooking piece 62a of the structural support member 62, it is necessary to excessively tension (excessively pull in) the depth dimension L (+ α) of the engaging groove 60c. There was such a problem.

[0006] Therefore, a main object of the present invention is to facilitate fixing of a film material while fixing the film material on a structural support while preventing excessive retraction.

[0007]

In order to solve the above problems, the present invention according to claim 1 provides a fixing structure for fixing a film material having an edge rope at a side edge portion to a structure support. Then, bring in a fixing member having an edge rope swallow portion and a pocket-shaped groove along the longitudinal direction of the member, insert the edge rope portion of the film material into the edge rope swallow portion of the fixing member, and fix the side edge of the film material. The structure is pulled up to a predetermined position in a supported state, and by the connecting hook member installed so as to engage with the hooked portion integrally formed on the structural support member and the pocket-shaped groove of the fixing member, respectively. There is provided a fixing structure for a film material, which is characterized in that a fixing member is fixedly held at a predetermined position.

According to the first aspect of the present invention, the member for fixing the film material is composed of two members, that is, the fixing member connecting and locking member. At the time of fixing, if the fixing member that supports the side edge of the film material is pulled in by a required distance, the fixing member is fixed to the hooked portion by the connecting locking member while maintaining that state. It becomes possible to easily fix the film material while eliminating the drawing of the film.

According to a second aspect of the present invention, a notch is provided in a part of the one-side projecting piece forming the pocket-shaped groove of the fixing member, and the engagement of the connecting hook member is provided from the notch. A fixing structure for a film material according to claim 1, wherein the fixing structure is provided.

According to a third aspect of the present invention, the connecting hook member is provided with a stopper screw which is screwed in from the outside and whose tip is engraved in the hooked portion of the structural support. A fixing structure for a film material according to any one of the above is provided.

According to a fourth aspect of the present invention, there is provided a fixing structure for fixing a film material having an edge rope on a side edge portion to a structural support, wherein the edge rope swallowing portion extends along the longitudinal direction of the member. And a fixing member having a pocket-shaped groove, and the edge rope portion of the fixing member is inserted with the edge rope portion of the film material to pull it to a predetermined position while supporting the side edge of the film material. At a predetermined interval position, so as to penetrate through both the through holes formed in the hooked portion integrally formed with the structural support member and the one-side projecting piece forming the pocket-shaped groove of the fixing member. A fixing structure for a film material is provided, characterized in that the fixing member is fixedly held at a predetermined position by inserting a bolt and screwing the bolt into a nut arranged in the pocket-shaped groove.

According to the fourth aspect of the present invention, if the fixing member supporting the film material is pulled in by a necessary distance, the fixing member is fixed to the hooked portion by the bolts and nuts while maintaining the state. By doing so, it becomes possible to easily fix the film material while eliminating excessive retraction.
