Sealing, prevents the leak, infiltration and cushioning buffer effect of architectural construction, in underground installation, tunnel culvert, water delivery aqueduct, blocks water
It is widely used in the building structure such as dam, reservoir structures.
Due to deformation joint（Expansion joint）Need change in displacement repeatedly during building facilities use, including transversal stretching,
Longitudinal shear either multi-angle solid deformation, this requires rubber fastening bands to have the deformability of various dimensions, could always
It keeps sealing with the concrete structure of deformation joint.Existing rubber fastening band generally can realize preferable transversal stretching, when encountering
When multi-angle change in displacement, breakthrough is easily formed with the side contact position of deformation joint（Or the rubber body of rubber fastening band with
Because of the deformation coefficient of both difference between concrete, or due to aging of rubber body etc., seam can be formed between the two
Gap）, the ponding of upstream face cannot once be discharged in time, will be from breakthrough（Or in gap）It is immersed in inside concrete structure,
Seal failure finally is caused around rubber fastening band, and stealthy damage is caused to building structure, in view of the above-mentioned problems, some is only
Leak stopping process is increased in water belt construction, what is generally taken is chemical grouting method, can generate destruction to deformation joint concrete structure,
The permanent hidden danger of quality of unrepairable is formed, and increases maintenance cost.
Utility model content
The purpose of this utility model be just to provide one kind can adapt to deformation joint various dimensions deformation and it is simple in structure, sealing stop
The good novel rubber water stop of water effect.
To achieve the above object, technical solution used by the utility model is：
A kind of novel rubber water stop of deformation joint, including band body, are set to the deformation hole at body central axis,
It is described to be equipped with multiple sealing ribs side by side with body central axis both sides, it is characterised in that：Phase positioned at the deformation hole both sides
The cushion seal body made of foaming sealing material is set between adjacent sealing rib, and the cushion seal external surface is protrusion
Arc.
The additional technical feature for constituting a kind of novel rubber water stop of above-mentioned deformation joint further includes：
--- it surface and the band body and deforms hole in the cushion seal body and is bonded as one structure；
--- it is located at the water guide wing of the cushion seal body central axis both sides setting reversed acanthoid with body upstream face, it is described
The outside of the water guide wing compresses palette with deformation joint two sides；
--- the foaming sealing material is that foaming ethylene propylene diene rubber, foamed silastic or polyurathamc are constituted.
A kind of novel rubber water stop of deformation joint provided by the utility model compared with prior art, has following excellent
Point：First, since being located between it deforms the adjacent sealing rib of hole both sides for the waterstop is arranged by foaming sealing material system
At cushion seal body, the cushion seal external surface be protrusion arc, inner surface with body and deform hole it is Nian Jie, both protected
Demonstrate,proved its own and had enough deformabilities, can realize various dimensions deformation, buffer load impact, the surface of arc convex with
The side contact site fitting of deformation joint compresses more closely, realizes good sealing effect；Second, due to the waterstop by
Band body, the deformation hole being set at body central axis and positioned at body central axis both sides equipped with multiple water stopping ribs side by side
Item is constituted, and cushion seal body is bonded on the band body of deformation hole both sides, and overall construction is simple, easily manufactured, of low cost；Its
Three, due to constitute cushion seal body foaming sealing material be foaming ethylene propylene diene rubber, foamed silastic or polyurathamc,
Its light quality and there is stronger toughness, while the expanded material especially foaming ethylene propylene diene rubber and cement concrete have
There is similar deformation coefficient, adapts to multi-angle deformation, independent air bubble structure has good compression recovery performance and hydrophobic performance,
Buffer shock resistance it is splendid, keep the concrete structure dynamic tight ness rating of waterstop and deformation joint more preferable, flow be not susceptible to " around
It oozes "；Fourth, the water guide wing since reversed acanthoid being arranged positioned at the cushion seal body central axis both sides with body upstream face, the water guide wing
Outside and deformation joint two sides compress palette, compress to be formed with cushion seal body upper surface between the water guide wing of tilting and lead
Sink prevents moisture accumulation convenient for waterstop quickly is discharged in flowing water, permeates, keeps away to the contact site of deformation joint and waterstop
Waterstop is exempted from and seal failure phenomenon occurs.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the novel rubber water stop of deformation joint of the utility model；
Fig. 2 is another structural schematic diagram of the novel rubber water stop；
Fig. 3 is novel rubber water stop scheme of installation in deformation joint.
Specific implementation mode
Below in conjunction with the accompanying drawings to a kind of structure and work of the novel rubber water stop of deformation joint provided by the utility model
It is described in further detail as principle.
As shown in Figure 1, being a kind of structural schematic diagram of the novel rubber water stop of deformation joint provided by the utility model.
The structure for constituting the rubber fastening band includes band body 1, is set to the deformation hole 2 at 1 central axis of body, band 1 central axis of body
Both sides are equipped with multiple sealing ribs 3 side by side, are arranged between the adjacent sealing rib 3 of deformation 2 both sides of hole and are sealed by foaming
Cushion seal body 4 made of material, 4 outer surface 41 of cushion seal body are the arc of protrusion, 4 inner surface 42 of cushion seal body and band
