The cystosepiment 2 of 1 lower part of waterstop guarantees that the width between two pieces of formwork erections at deformation joint 3 is d.In buried 1 He of rubber fastening band
Cystosepiment 2 is isometric with deformation joint 3.
Then, special-shaped seal plate 4, and special-shaped seal plate 4 and deformation joint 3 are installed respectively in the top two sides of deformation joint 3
It is isometric, i.e., one piece of special-shaped seal plate 4 is all installed in every side, in the present embodiment, used abnormity seal plate 4 is that abnormity is zinc-plated
Steel plate for sealing water.As shown in Figure 1, the minimum spacing between two pieces of special-shaped seal plates 4 is corresponding with the predetermined width d of deformation joint 3.Such as
Shown in Fig. 2 and 3, every piece of special-shaped seal plate 4 is in class zigzag, and under upper successively comprising horizontal short slab 4a, plagioclase plate 4b,
Horizontally long plate 4c and tiltedly short slab 4d.Horizontal short slab 4a is laterally setting, and extends outside towards deformation joint 3.Plagioclase plate 4b and horizontal short slab 4a
Outer end be fixedly linked, downwards and towards close to deformation joint 3 direction tilt extend.The bottom end of horizontally long plate 4c and plagioclase plate 4b is solid
It is fixed to be connected and be laterally extended outside towards deformation joint 3.Oblique short slab 4d and the outer end of horizontally long plate 4c are fixedly linked, it is downward and away from
The direction of deformation joint 3, which tilts, to be extended.In the present embodiment, if horizontal short slab 4a, plagioclase plate 4b, horizontally long plate 4c and oblique short slab 4d
Extension width is followed successively by D1, D2, D3, D4, then D1=20mm, D2=100mm, D3=150mm, D4=30mm；Also, plagioclase plate
The angle of 4b and horizontally long plate 4c is 60 °, and the angle between horizontally long plate 4c and oblique short slab 4d is 150 °.And special-shaped seal plate 4
Alongst be welded with a M10 bolt (pouring preceding welding) every 100mm on plagioclase plate 4b, on horizontal short slab 4a every
250mm is provided with the internal thread hole of a M5.
Above-mentioned special-shaped 4 points of seal plate is welded on reinforcing bar and is fixed, casting concrete is conserved after concreting is complete,
After intensity reaches building requirements, form removal forms concrete floor 5.Due to pacifying before pouring concrete in two sides
Special-shaped seal plate 4 has been filled, has been 60 degree of angles between two pieces of special-shaped seal plates 4, therefore the Concrete in Natural formation angle for pouring out is
The V-shaped groove of 60 degree and upper and lower opening.
Then, cystosepiment 2, distance of 2 top of cystosepiment to horizontally long plate 4c are packed into 3 top of deformation joint by V-shaped groove
For 50mm；Special-shaped rubber fastening band 6 is installed along the inner wall of the plagioclase plate 4b of two sides in V-shaped groove again；And cystosepiment 2 and different
Shape rubber fastening band 6 is isometric with deformation joint 3.As shown in Figures 2 and 4, special-shaped rubber fastening band 6 includes two bevel edge portion 6a and one
A bottom 6b；Two bevel edge portion 6a are corresponding with the plagioclase plate 4b of two sides difference, and fitting plagioclase plate 4b inner wall extends；Bottom
The two sides top of portion 6b is connected with the bottom end of two bevel edge portion 6a respectively, and is formed in 3 top of deformation joint, is in upward opening
Groove-like.In the present embodiment, if the height of the bottom 6b of special-shaped rubber fastening band 6 is D4, then D4=35mm, two bevel edge portions
The width of 6a is equal with plagioclase plate 4b.
As illustrated in fig. 1 and 2, above-mentioned special-shaped rubber fastening band 6 is fixed with pressing plate 7 and fixing piece 8 and is fitted in plagioclase
On the inner wall of plate 4b.In the present embodiment, used pressing plate 7 is zinc-coated flat steel sheet pressing plate, and isometric with deformation joint 3；Fixing piece 8
For multiple groups M10 nut.There are multiple fixation holes to match along length is uniformly distributed on pressing plate 7, special-shaped rubber fastening band 6, such as
Shown in Fig. 5, the spacing of fixation hole is 100mm, fixing piece 8 protrude into these fixation holes with the M10 bolt that is stretched out on plagioclase plate 4b
It mutually tightens to realize and be fixed.
Finally cover cover panel 9, in the present embodiment, used cover panel 9 is zinc-coated flat steel sheet cover panel, and with deformation
It is isometric to stitch 3.As shown in fig. 6, multiple U-lags are laid in the two sides edge of the cover panel 9, on the length direction along deformation joint 3,
The hole site M5 on these U-lags and horizontal short slab 4a corresponds, separation 250mm；U-lag and connecting hole pass through fixing piece
10 are fixedly linked, and are fixed on the special-shaped seal plate 4 of two sides so that the lid of cover panel 9 be closed.In the present embodiment, fixing piece 10 is heavy
Head screw.There is certain sliding surplus when can guarantee that 3 both sides of deformation joint are expanded with heat and contract with cold as fixing hole using oblong slots.
Based on above-mentioned water-stopping method, in buried rubber fastening band 1 completed with concrete structure pouring once mounting, play first
Road waterproof action, special-shaped seal plate 4 both play the role of sealing effect, while playing fixed special-shaped rubber fastening band 6.Special-shaped rubber
Glue waterstop 6 plays second waterproof action, plays the role of a seal washer by tightening pressing plate fixing piece 8.If the later period
It in use process, finds localized seepage, cover panel 9 can be opened, panel nut is tightened to leakage, or directly replace special-shaped rubber
Glue waterstop 6, later period maintenance is very convenient.
Above is only the illustration done to technical solution of the present invention.Underground concrete structure according to the present invention
The water-stopping method of deformation joint is not merely defined in the structure described in above, but with claim limited range
