Wherein stem protrusion（2）, stem groove（3）, sealing rod groove（1）It is respectively positioned on structure stem（4）In.Sealing rod is recessed
Slot（1）Positioned at stem protrusion（2）On.Stem groove（3）Positioned at stem protrusion（2）The left side.
Wherein retaining groove（7）, tail protrusion（5）, water expandable waterstop（6）It is respectively positioned on structure tail portions（8）In.Meet water
Expansion sealing strip（6）Positioned at retaining groove（7）On.Tail protrusion（5）Positioned at retaining groove（7）The left side.
Stem protrusion（2）With retaining groove（7）Agree with, i.e. stem protrusion（2）Retaining groove can be completely embedded in（7）In, and
There are other redundant spaces.Stem groove（3）With tail protrusion（5）Agree with.Water expandable waterstop（6）With sealing rod groove
（1）Agree with.
Precast concrete connecting sewing waterproof construction described in the utility model, wherein water expandable waterstop（6）, pass through
Screw is fixed on concrete interface.
The utility model mixes the precast concrete connecting sewing waterproof construction, wherein water expandable waterstop（6）For rubber
Glue sealing rod.
Precast concrete connecting sewing waterproof construction described in the utility model, wherein water expandable waterstop（6）It is fixed on
At the lower surface of water-proof concrete horizontal construction joint, and water expandable waterstop（6）It is extended to from one end of water-proof concrete
The other end.
Precast concrete connecting sewing waterproof construction described in the utility model, wherein reserved steel bar hole（9）Steel can be passed through
Muscle, casting concrete ensure the intensity requirement of connection crack structure.
After adopting the above scheme, when water-proof concrete is in a humid environment in use, due to structure stem and structure tail
Portion combines closely, and micro water may reach retaining groove along gap（7）, due to retaining groove（7）With stem protrusion（2）
Mutually agree with, so in retaining groove（7）Place forms the platform that is filled with water, and seepage water is circulated to the infiltration of lower layer and leads in isolation
Road.At this time due to water expandable waterstop（6）The side of upstream face, water-swellable is leaned on to stop positioned at water-proof concrete through-thickness
Water bar（6）Water-swellable, until being full of reserved space, water-swellable concrete is tightly wrapped up by surrounding concrete, is contacted
More closely, infiltration path is blocked to a certain extent, is reduced seepage pressure, is further promoted the waterproof effect of the utility model.
In addition, can be in retaining groove（7）Smear cement based penetration crystallization type water proofing paint, the silicon dissolved out in such earth material in place
Ketone ion can be chemically reacted with calcium ion of the superficial water in concrete in diffusion, with concrete, be generated insoluble
In the calcium silicate hydrate of water, crystalline solid is full of capillary interstice and is combined with concrete integral, blocks inside concrete
Capillary channel prevents water from leaking to keep concrete fine and close.Also, such coating has catalysis characteristics, once meeting water can not
The biochemical reaction of stopping pregnancy, by such applying material retaining groove（7）Place, in retaining groove（7）It is extra in the case that humidity is aqueous
Water can endlessly be chemically reacted with such coating, inside the constantly growth of the crystalline solid of generation and fill concrete
Capillary porosity, keep structure finer and close, make component have auto-mending heal water-proof function.
The utility model is by three layers of waterproof guarantee, the waterproof ability of the junction of lifting assembly, while can be by pre-
It stays reinforced hole to connect component, component is linked together, and promote overall intensity.The utility model is simple in structure, making side
Just, construction site Fast Installation can be carried out after the good prefabricated components work of factory process,
Description of the drawings
Fig. 1 is the elevation of the utility model component.Wherein（a）For structure stem,（b）For structure tail portions.
Fig. 2 is the side view of the utility model component.
Wherein, 1 is sealing rod groove, and 2 be stem protrusion, and 3 be stem groove, and 4 be structure stem, and 5 be tail protrusion, 6
