The utility model content
The technical problem that the utility model will solve just provides and a kind ofly can satisfy waterproof forward and transversal stretching, can also adapt to impermeability, high cracking resistance, ageing-resistant waterproof stretching device.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: comprise the fluted body waterstop; Be provided with seal plate above the said fluted body waterstop, the middle part of seal plate is the box structure that is provided with at least one through hole, is provided with polysulfide rubber sealing piece above the seal plate.
Its additional technical feature is: the groove of said waterstop is U type, V-type; It is protruding that the upper end of said seal plate is provided with the T type, and the L type corrosion resistant plate that is arranged on the seal plate is embedded in T type high spot; Described L type corrosion resistant plate is provided with the water-swellable adhesive tape; Through hole on the said seal plate is polygon, circle, ellipse; Described through hole is one or more.
When a kind of waterproof stretching device that the utility model provided is installed; Cell body in the aqueduct expansion joints both sides is reserved mounting groove; Fluted body waterstop, seal plate, L type corrosion resistant plate, polysulfide rubber sealing piece are installed in the place, shrinkage joint successively; The box structure at seal plate middle part occupy between two L type corrosion resistant plates and is choked, and the T type convexity of seal plate is hooked L type corrosion resistant plate, and the long limit of seal plate both sides is squeezed on the mounting groove by top L type corrosion resistant plate and following waterstop simultaneously; The plane is provided with the water-swellable adhesive tape on L type corrosion resistant plate, can prevent sealing around oozing.In order to improve the performance of this waterproof stretching device, the long limit of L type corrosion resistant plate, seal plate both sides and two side planes of fluted body waterstop are fixed on the cell body with bolt, nut etc.At last at the mounting groove backfill third newborn mortar.
A kind of waterproof stretching device that the utility model provided adopts triple waterproof, and the upper strata is a polysulfide rubber sealing piece, and polysulfide rubber has excellent weather resistance, and its intensity is low, and elongation rate is high, and water-tolerant is good with concrete bonding property, plays the first heavy waterproof.The rubber seal plate is adopted in the intermediate layer, and the middle part of seal plate is the box structure that is provided with at least one through hole.Rubber has better elastic and good weatherability, and wide, heat-resisting, the anti-ozone of its high low temperature scope of application, acid-proof alkaline are preeminent.Adopt precommpression to install when seal plate is installed, make seal plate when flexible, be in compressive stress state all the time, it is stressed more reasonable to make, avoids the destruction of tensile stress.The box structure at seal plate middle part can satisfy bigger stroke, offers the strong resiliency supported of upper strata polysulfide rubber sealing piece, plays the second heavy waterproof.Lower floor adopts the fluted body waterstop; Material therefor has good weatherability, anti-ozone, chemical-resistant resistance and ageing-resistant performance, has good oil resistivity, anti-flammability, ultra-violet resistance, and its character is superior to General Purpose Rubber; Have good comprehensive performances, play triple waterproof.Triple waterproof constructions are worked in coordination, and can satisfy waterproof forward and transversal stretching, can also adapt to impermeability, high cracking resistance, ageing-resistant.Owing to receive external force or difference variation to cause cell body to rise or when sinking, drive the waterproof stretching device and take place to rotate up and down, avoid the destruction of stretching device and beam-ends concrete to come off when the capillary groove end of body, guaranteed the interior water flow stationary safe operation of cell body; When taking place under external force effects such as wind-force than the large span waterproof laterally to move, can move about the waterproof stretching device, thereby guarantee that the stretching device water flow stationary that is not damaged do not pass through; The combination of polysulfide rubber sealing piece and box-shaped seal plate can be satisfied various distortion such as level of water, inclination, distortion in addition.
Description of drawings
Fig. 1 is the structural representation of a kind of waterproof stretching device of the utility model.
The specific embodiment
Further specify below in conjunction with the structure of accompanying drawing a kind of waterproof stretching device that the utility model provided.
As shown in Figure 1; A kind of waterproof stretching device of the utility model comprises U type waterstop 1, is provided with seal plate 2 above the waterstop 1, and the middle part of seal plate 2 is the box structure that is provided with polygon through hole 3; The upper end of seal plate 2 is provided with T type protruding 4; The L type corrosion resistant plate 5 that is arranged on the seal plate 2 is embedded in protruding 4 places of T type, and L type corrosion resistant plate 5 is provided with water-swellable adhesive tape 6, is provided with polysulfide rubber sealing piece 7 above the seal plate 2.The groove of waterstop 1 also can be V-type, and through hole 3 also can be circle, ellipse, and through hole 3 can be one or more.
