本発明は例えば可撓性膜製起伏堰、隔膜付タン
ク等に於ける可撓性膜材の基礎への気密固定方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a method for airtightly fixing a flexible membrane material to a foundation in, for example, a flexible membrane undulation weir, a tank with a diaphragm, or the like.

があつた。 Carpet (upper layer sheet) as shown in Figure 1
1 and a seal sheet (lower layer sheet) 6 are fixed with a clamping bar 7 to form a bag body to prevent leakage of internal fluid. A conventional airtight method is as shown in Fig. 2. Ta. That is, the cover sheet 10 is adhered to the seal sheet 6 in advance, and at the time of installation, the end of the cover sheet 10 is pushed in with the base plate 11, and the rest of the cover sheet 10 is wrapped around the clamping bar 7 together with the carpet 1 and fixed. According to this method, leakage from part A can be completely prevented. On the other hand, a sealing material 12 is filled between the carpet 1 and the cover sheet 10 in order to prevent leakage from part B. However, when the weir expands, tension acts on the carpet 1, causing the carpet 1 and the sealing material 12 to Leakage sometimes occurred because shear separation occurred between the two, creating a fluid passage.
即ち従来にあつては下記の様な問題点があつ

シール効果を失う。このためカーペツトとカバー
シートの間隙より内部流体が漏れる。 Since the carpet and cover sheet are not bonded in advance, even if a sealing material is filled at the time of installation, when tension is applied to the carpet, the sealing effect is lost due to peeling due to shearing. As a result, internal fluid leaks from the gap between the carpet and the cover sheet.

ことを特徴とするものである。 That is, in the method of airtightly fixing a flexible membrane material to a base of the present invention, when two sheets of flexible membrane material are fixed to a base to form a bag body, the bag body is fixed near the end of the upper sheet. Glue one end of the cover sheet to the part that will become the inside surface of the cover sheet, overlap the end of the lower layer sheet and the other end of the cover sheet, and attach the part of the cover sheet that will be glued to the upper layer sheet to the base plate described below. It is characterized in that it is pressed down and fixed with a length margin between the parts pressed down.

ブスクリユー１６で止める。 Referring to FIG. 3, the present invention will be explained using an example in which the present invention is applied to an undulating weir made of a flexible membrane. At the factory, one end of the cover sheet 10 is glued to the inside surface of the bag of the carpet 1 (upper layer sheet) in advance, and at the time of installation, a seal sheet 6 (lower layer sheet) is laid on the riverbed foundation 3, and the seal sheet is placed at the position of the anchor bolt 4. 6 and cover sheet 10, pass the anchor bolt 4 through it,
A base plate 11 is installed thereon. Then connect the ends of the carpet 1 to the rod 13 and tube 14.
It is wrapped around the base plate 11 and pressed onto the base plate 11 using a clamping bar 7. Next, tighten the nut 15 onto the anchor bolt 4 from above the clamping bar 7, and then tighten the rod 13 and tube 1.
A resin 17 is filled between the holes 4 and 4 and hardened. Additionally, a carpet 1 is installed to protect the clamping bar 7.
Place the end on the clamping bar 7 and fix it with the drive screw 16.

で安全である。 According to this method, since the carpet 1 and the cover sheet 10 are bonded together, leakage from the D portion is completely eliminated. Also, regarding leakage from part C, if sealant 12 is filled between seal sheet 6 and cover sheet 10 at the time of installation, it will be suppressed by base plate 11 from above and tension will be applied to seal sheet 6. Since the sealant does not peel off due to shearing, complete airtightness is maintained. Furthermore, the cover sheet 10 can be easily installed if there is a margin 18 between the part to be adhered to the carpet 1 and the part pressed down by the base plate, and even if tension is applied to the carpet 1, the cover sheet 10 is not under tension. It is safe because it does not work.
なお本発明による気密をさらに完全にするため

通り据付時のシール材の充填が最も容易かつ確実
なものである。 Note that if the seal sheet 6 and cover sheet 10 are also glued together to form a bag body in order to further improve the airtightness according to the present invention, it will be difficult to attach the inlet/exhaust (water) port 5 shown in FIG. 1 during installation. Therefore, the airtightness between the seal sheet 6 and the cover sheet 10 is most easily and securely achieved by filling the seal material at the time of installation as in the present invention.

等の効果を有する。(Effects of the Invention) According to the fixing method of the present invention as described above, since the upper layer sheet (carpet) and the cover sheet are bonded in advance, leakage of fluid from the gap between the upper layer sheet (carpet) and the cover sheet can be prevented. If the gap between the lower sheet (seal sheet) and cover sheet is filled with sealant, no tension will be applied to the lower sheet (seal sheet), so the sheet effect will be maintained without shearing and peeling of the sealant. . Therefore, it is possible to prevent fluid from leaking from the gap between the lower sheet (seal sheet) and the cover sheet.
