In one embodiment, a first part of the detachable water stop strip 3 protrudes away from the deformation joint side, and a first sealing cavity is formed between the lower surface of the first part and the deformation joint; a second sealed cavity is formed between the support bracket 5, the cover plate 7 and the part of the upper surface.
The pressure-bearing performance of the detachable water stop 3 in the deformation joint waterproof structure mainly has two influence factors: firstly, the bolt 4 applies fixing pressure on the water stop belt; the other is the air pressure difference between the closed area (the second sealed cavity) and the outside, and the total pressure formed by the pressure generated by the fixed pressure and the air pressure difference is overcome to ensure that the water breaks through the detachable water stop 3, so that the waterproof sealing performance of the structure can be improved by the closed space (the second sealed cavity).
That is to say, the detachable waterstop 3 of the deformation joint waterproof structure is in a closed space, so that the detachable waterstop 3 can bear larger pressure, and the waterproof sealing performance of the deformation joint structure can be improved.
Because this coupling mechanism is mainly located this second seal chamber body, this coupling mechanism's dimensional requirement is: only the cap of the bolt 4 in the sealed area is required to be ensured not to touch the bottom surface of the cover plate 7.
On the whole, the deformation joint waterproof construction that this application provided only adopts a waterstop, and the construction is simple very much, and it is extremely convenient to pour, has brought very big facility for engineering constructor, greatly reduced the engineering because of the not high possibility that leads to deformation joint structure waterproof performance to weaken of workman construction technique.
Specifically, detachable waterstop 3 among this movement joint waterproof construction is fixed through detachable coupling mechanism, seals through apron 7 moreover, forms seal chamber, can not only improve waterproof performance, can also make this kind of movement joint structure if the later stage takes place the seepage, can conveniently change the material and repair, saves a large amount of costs and man-hour when resuming the waterproof ability of structure.
In this specification, above-mentioned movement joint waterproof construction, simple structure, the construction degree of difficulty is low, does not have the component of formula of burying in addition, later stage if the seepage maintenance very simple and convenient only need open apron 7 and control can. And the detachable water stop 3 is positioned in a closed space, so that the water stop can bear larger pressure, and the waterproof sealing performance of the deformation joint structure can be improved.
