を有する伸縮止水継手に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an expansion water stop joint having a reinforcing chain mat that is attached to a structure installed on underwater ground or water-containing ground.
従来、水底地盤または含水地盤に設置される構
造物に取付けられる伸縮止水継手としては、第４

Conventionally, as expansion water stop joints installed in structures installed on underwater ground or water-containing ground, the fourth
As shown in the figure, each flange 2 of the rubber waterproof material 3 consisting of a grooved portion 1 and flanges 2 continuous to both sides thereof is superimposed on an adjacent structure 4, and the surface of each flange 2 is An expansion joint is known in which a clamping member 5 extending in the longitudinal direction of the flange is superimposed on the flange, and the flange 2 is tightened and fixed to the structure 4 via the clamping member 5 by a clamping bolt 6. .
前記従来の伸縮止水継手の場合は、水圧に対し
ゴム製止水材３における溝形部分１のみが抵抗す
るので、大きい水圧に対する強度が弱いという問
題がある。
In the case of the conventional expansion water stop joint, only the groove-shaped portion 1 of the rubber water stop material 3 resists water pressure, so there is a problem that the strength against large water pressure is weak.
この対策として、ゴム製止水材３の肉厚を、大
きな水圧が作用しても破損しない程度に厚くする
ことが考えられるが、この場合は、ゴム製止水材
３の製作費が著しく高くなり、かつゴム製止水材

手方向に弯曲しにくくなるので、構造物の止水材
取付部に小半径の弯曲部や屈折部があるときも、
ゴム製止水材３の取付けが困難になる。 As a countermeasure to this problem, it is possible to increase the thickness of the rubber water stop material 3 to such an extent that it will not be damaged even when large water pressure is applied, but in this case, the manufacturing cost of the rubber water stop material 3 would be extremely high. In addition, the elasticity of the rubber water stop material 3 in the width direction deteriorates, so the gap between the tightening bolts 6 in adjacent structures and the gap between the bolt holes of each flange 2 in the rubber water stop material 3 are , if there is a relatively large difference, it will be difficult to install the rubber water stopper 3, and the rubber water stopper 3 will be difficult to install.
If the wall is too thick, it will be difficult to bend the rubber water stop material in its longitudinal direction, so even if there is a small radius curve or bend at the part where the water stop material is attached to the structure,
It becomes difficult to attach the rubber water stop material 3.
また他の対策として、耐水圧性を高めるため

材を重合させた状態で、ゴム材を加硫により接着
結合するので、加硫時間が長くかかり、そのため
ゴム材が過剰加硫になつて接着結合部の結合強度
が低下するという問題がある。 Another possible measure is to embed a reinforcing core material made of canvas or sag-like material in the rubber waterproof material in order to increase its water pressure resistance. In addition, since the longitudinal bendability deteriorates, it becomes difficult to attach the waterproof material to the structure. Furthermore, in the case of large submerged structures such as submerged boxes, it is necessary to adhesively bond the ends of multiple water stop materials by vulcanization (heating and pressure) at the construction site of expansion water stop joints. Since the rubber material is adhesively bonded by vulcanization with the reinforcing core material polymerized, the vulcanization time is long, which causes the problem that the rubber material becomes over-vulcanized and the bond strength of the adhesive bond decreases. be.
