2a is covered over the entire length with a rubber plate 12, the end of the membrane 13 is placed on the rubber plate, and the end of the membrane is pressed with channel-type pressers 15, 15 through a synthetic rubber cover 14, This presser body is fixed on the connecting plate 11 together with the connecting plate 11a by nuts 16, 16 attached to the upper ends of bolts 7, 7 fixedly standing up on the membrane support plate. Due to the tightening force of the nut 16, the rubber plate 12 and the rubber cover 14 tightly clamp the end of the membrane, ensuring airtightness between the presser body 15 and the membrane support plate 2. Rubber cover 1
4 is bent upward to cover the entire length of the presser body 15, and the locking side 14a at the end is covered with the gasket 1.
It is inserted into the mounting grooves 17a provided at both ends of 7. The engaging portion 17b at the bottom of the gasket 17 is press-fitted between the presser bodies 15, 15, and the locking side portion 14a is fixed to the gasket 17 by press-fitting the presser bar 18 into the groove 17c at the center of the upper part of the gasket. be done. With this gasket and the rubber cover 14, the airtightness of the membrane supporting portion can be more effectively ensured.

The intermediate portions of the holding bodies 15 are fixed to the membrane support plates 2, 2a by bolts 19 and nuts 20, as shown in FIGS. 1 and 2, and the membrane 13 is also supported at the same time. This bolt is previously fixedly erected on the membrane support plate.

Next, attachment of the connector 3 will be explained.

First, attach the clamping plate 4 and spacer pipe 6 to the bolts 7, 7 while rotating 180 degrees from the position shown by the solid line in Figure 5, then position the cable 1 in the recess 4a, and then attach the clamping plate 5 to the bolt. When the clamping plates 4, 5 are clamped by the concave portions 4a, 5a of the clamping plates 4, 5, and the nuts 10, 10 are attached to the ends and tightened, the clamping plates 4, 5 are tightly connected to the cable 1, so that the coupling tool is suspended from the cable. Fixedly attached. Connecting devices are attached to predetermined locations on the cable in the same manner.

To attach the membrane holder and membrane 13, first attach the connection plate 11, membrane support plate 2, rubber plate 12, membrane 13,
By attaching the rubber cover 14, presser body 15, and connection plate 11a in a polymeric manner and tightening the nuts 16, the membrane holder and membrane 13 are simultaneously fixed to the bolts 7, 7, and the membrane 13 is attached to the membrane support plate 2, 2a.

After press-fitting the gasket 17 between the presser bodies 15, 15, the ends of the rubber cover 14 are bent toward the gasket side to cover the presser body, and the locking sides 14a,
14a into the mounting grooves 17a, 17a of the gasket, and insert the presser rod 18 into the recess 17c of the gasket.
Press-fit it to finish sealing the upper part of the presser foot.

When attaching the connector 3 to the cable, if a mark 21 with a length L equal to the length of the clamping plate 4 (or 5) is made on the cable 1 as shown in Fig. 2, the connector can be positioned accurately. easy to do,
Moreover, if this mark is matched to the length of the clamping plate 5 that will be located on the lower side, the mark will not be directly visible from below due to the existence of the clamping plate 5, and the aesthetic appearance will not be impaired.

In addition, in order to allow the connector 3 to stand upright directly above the cable 1, as shown in FIG. By pulling the mark and aligning this mark with the mark line during installation, the connector can be aligned in the rotational direction, which is convenient for work.

The same applies when connecting other membrane support plates to the cable 1. In addition, the connecting device 3, the membrane support plate, and the cable 1a are connected in the same manner using a connecting device, but in this case, for example, the distance between the membrane support plate 2a ₁ and the cable 1a is the same as that of the membrane support plate. Since it is longer than the case of 2a, it can be adapted by increasing the height of the reaction force receiving plate 8 of the connector.

As shown in the above example, attach the membrane holder to the membrane support plate 2 and presser 1.
5, and if it is attached directly to the bolts 7, 7, there is no need for a supporting member to attach the membrane holder to the bolts, the number of attachment steps is reduced, construction is easier, and the membrane can be attached at the same time. It can be installed and work can be done more quickly.
If the connector is attached to the cable at the connecting portion of the membrane support plate, the connection of the membrane support plate and the connection of the membrane support plate and the cable can be performed simultaneously.

The connecting tool may be installed at the bolt 19 position. In this case, it does not have the function of connecting the membrane support plates 2 to each other. In this case, the connecting plates 11, 11a are unnecessary.
