As described above, the box-shaped members 14 and 14 'are pivotally fixed to the shaft portion of the socket 6 by bolting the take-out metal fitting 10 and the mounting metal fitting 9 to each other.
Has to be installed.

On the other hand, the film continuous treatment of the film materials 3, 3 facing each other through the wire 2 other than the wire fixing portion is performed as shown in FIGS. 5A and 5B.

That is, as shown in the drawing, holding U bolts 4 are attached to the wires 2 at predetermined intervals, and a holding plate 7 for holding the wires 2 is attached to the U bolts 4, and the tip of the holding plate 7 is tightly fixed to the aluminum channel 12. The aluminum channel 12 is engaged with a long aluminum channel 8 extending along the wire 2 with a predetermined gap 21, and the plate portion for the film material fixing joint is provided above the wire 2 (long aluminum channel 8). To form.

On the plate portion, the end portion of the film material 3 is folded back and heat-welded 11 and processed into a bag-shaped portion 20 into which the rope 13 is inserted. The film material 3 is fixed to the wire 2 by tightening bolts 23 arranged at plural intervals in the direction.

Since it is important to obtain airtightness and watertightness in this fixed joint part, the fastening part of the membrane material 3 is the membrane material 3
It is good to fix it through a synthetic rubber cushion 24 so that it will not be damaged by repeated movements such as wind pressure.

The bent portion of the wire 2 is ensured by ensuring that the joints of the long aluminum channel 8 and the long metal member 22 manufactured to have the same length are aligned with each other.

The U-bolt 4 is arranged at the joint of the long aluminum channel 8 in a crotch manner.

The cover for the long hardware 22 is a neoprene cover.
It is made by covering 25, which has a thick portion 26 formed at one end and a fitting groove provided in the thick portion 26 is formed in the metal piece 22 by locking. It is fitted to the projecting portion 27, and the thick portion
The seal for the gap between 26 is a roll-shaped gasket.
It is done by inserting 28 into the insertion groove attached to the thick portion 26 at the site and making it adhere.

The joint between the film continuous processing section and the wire fixing section is formed as shown in FIG.

That is, at the end of the film continuous processing part, the side end of the long aluminum channel 8 is dammed 30 so that the aluminum channel 12 is not disengaged, while at the end of the wire fixing part, the film material 3 is The spacer 33 is interposed so that the tension level 32 is the same, and the carry-out metal fitting 10 'is fixed to the wire 2 by the U bolt 4, so that the long aluminum channel 8 and the mounting metal fitting 9 are at the same level. There is.

[Problems to be solved by the invention] In the above construction, first, the box-shaped members 14 and 14 'are bolted to the shaft portion of the socket 6 so as to establish a pivoting relationship. It has a mounting member (carrying-out metal fitting 10 and mounting metal fitting 9), and there are many constituent elements, so it is necessary to take a lot of clearance, the shape and size increase, and the number of man-hours at the time of construction is large. There is a problem that leakage is likely to occur.

Incidentally, the above problem also applies to the carry-out metal fitting 10 'of the wire fixing portion.

Next, as shown in FIG. 6 described above, the long aluminum channel 8 and the mounting bracket 9 have a predetermined gap 34 at the same level at the joint between the membrane continuous processing section and the wire fixing section. However, in this gap 34, the above-mentioned FIG.
Like the aluminum channel 12 in the above, since there is no integrated member that crotches between the plate parts for the membrane material fixed joints that face each other and presses both, there is no restraint and the protective member during inflation is received. Since it is not placed, the light film continuous processing side first rises to generate a step, and there is a problem that the film material 3 bites into the gap 34 and is damaged frequently.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide a socket 6 in a wire fixing portion and a component fixed to the wire 2. An attempt is made to provide a protective member that is simplified and has excellent workability and excellent air leakage prevention, and that can be integrated with a joint portion with a continuous membrane treatment portion to prevent damage to the membrane material. It is a thing.

[Means for Solving the Problems] In order to achieve the above object, the protective member according to the present invention has a bellows between box halves which are divided into two with a predetermined interval sandwiching the hinge portion of the socket of the wire fixing portion. In the wire fixing part protection member connected by a synthetic rubber expand joint of the mold, the two box molds are cast by aluminum and the mounting bracket part for the socket shaft part is taken out and attached to the lower end part. The box-shaped lower end on the non-proximal end side is provided with a saddle part for attaching a wire and a tongue part for biting into the side end opening of the long aluminum channel of the continuous membrane treatment part.

[Operation] The double-box type is directly attached to the shaft portion of the socket 6 and the wire 2 through the attaching bracket portion and the attaching saddle portion without any intervening member, and airtightness is secured. Further, in the box type on the non-base end side, it is engaged with the side end opening of the long aluminum channel 8 of the continuous membrane treatment unit through the biting tongue portion to be integrated, which is suitable for inflating. However, no step is formed between the film continuous processing section and the wire fixing section.

[Example] An example will be described with reference to the drawings.

1 and 2, at the lower ends of the box dies 35, 35 'according to the present invention, the brackets 36, 36' for joining to the socket 6 shaft 6a are integrally formed at the lower end of the butt against each other by aluminum casting. It is shaped and bolted 37 directly to the shaft 6a without any intervening components.

Further, the connection with the wire 2 of the box-shaped box 35 on the non-base end side is carried out by the crimping of the bolt through the attaching saddle part 38 having a shape at the lower end of the tip.
At 39, it is also fixed directly to the wire 2 without any intervening components.

Further, a tongue piece portion 40 is provided at the tip of the saddle portion 38 so as to project into the side end opening 8a of the long aluminum channel 8 at the end of the continuous membrane processing portion.

Then, with respect to the inflating motion, the long aluminum channel 8 and the box mold 35 can be completely matched with each other, and no gap or step is generated.

Of course, the aluminum channel 8'fixing part is secured around the edges of the box type 35, 35 ', but the gasket stopping peripheral grooves 41, 41' are also integrally formed, and the bellows type synthetic rubber expand joint. Corresponding to this, 42 is integrally formed with a gasket 43 for sealing between the film material 3 and the box molds 35, 35 as shown in FIG.

"Effect of Invention" Since the present invention is configured as described above, it has the following effects. Air leakage from the joint was reduced due to the reduction in the number of members.

Since only the aluminum cast cover needs to be set in order to put it in the membrane construction, the number of man-hours during construction has been reduced (improvement of construction ease and reliability).

The damage to the film material due to the gap in the gap between the continuous film processing part and the wire fixing part, which was the maximum weak point during inflation, was eliminated.
