Accompanying drawing explanation
Fig. 1 is the signal of the removable skin combined water sealing structure that the present invention stitches for xoncrete structure
Figure.
Detailed description of the invention
As it is shown in figure 1, the removable skin combined water sealing structure for xoncrete structure seam of the present invention,
At the both sides, structural jointing 3 position of concrete surface fluting or preformed groove, form water stopping trough, every side channel width
20～25cm, groove depth 4～5cm, U-shaped rubber fastening band 1 is bonded at the bottom of water stopping trough by binding agent, and
It is positioned at two sealings that structural jointing 3 both sides are parallel with structural jointing by many group stainless steel bolts 6 are fixing
Pressing plate 5, is pressed on U-shaped rubber fastening band 1 in the lower surface of water stopping trough, U-shaped rubber fastening band 1
In protruding U-shaped portion position 2 insert structure parting 3, the space material 7 in structural jointing and projection
Inject 2～4cm thick fluid sealants 4 between U-shaped portion position 2, fill bullet on U-shaped rubber fastening band 1 top
Property material 9, water stopping trough is filled and led up, the water stopping trough external coating elastic water-proof coating 8 after filling and leading up, elastic
Waterproof coating 8 strides across the xoncrete structure bonding of whole water stopping trough and top layer, both sides, and both sides respectively overlap width
8-12cm。
One layer of tire base grid cloth is added bottom elastic water-proof coating 8.
Described elastomeric material 9 is elastic mortar or rubber powder.
Described stainless steel bolt 6 uses pre-buried pattern or implants pattern, the diameter of bolt, length, spacing energy
Guarantee that sealing pressing plate, the effective of U-shaped rubber fastening band fix.
Described fluid sealant 4 uses polysulfide sealant.
Described U-shaped rubber fastening band 1 thick 6～10mm, bond the every side of width 15～20cm, sealing pressing plate 5
Using plastic-steel or stainless steel, and corresponding stainless steel bolt has stayed preformed hole, sealing pressing plate 5 is wide
5～8cm, thick 6～10mm.
Described elastic water-proof coating 8 thickness is not less than 1.5mm, hot strength >=10MPa, elongation at break
>=350%, 2.0MPa≤100% stretch modulus≤6.0MPa, 0.4Mpa/2h are waterproof, with base adhesive
Intensity: be dried basal plane >=2.0MPa, moisture substrate >=1.6MPa.
The present invention is by using the measures such as fluid sealant, U-shaped rubber fastening band, elastic water-proof coating, it is achieved
Multilayer flashing, therefore good water-proof effect.By waterstop " U " position is arranged at structural jointing, and
Use the measures such as fluid sealant and elastic water-proof coating that tensile elasticity amount is bigger issuable with commensurate structure
Moderate finite deformation.Sealing is guaranteed by measures such as binding agent, sealing pressing plate, stainless steel bolt, elastic mortars
With xoncrete structure laminating closely, be connected firmly, replaceable.By main waterproof measure is arranged in knot
Structure top layer, pitch of bolts is adjustable measure of Denging, it is to avoid conflict with new, old concrete structure reinforcing bars.
Work progress is as follows:
1, pre-buried or implant stainless steel bolt, as use pre-buried time can use band steel position fix, spiral shell
Bolt diameter is generally 10～14mm, single is about 10cm, and wherein embedment deep about 6～7cm, pitch of bolts can
Suitably adjust, typically about 20cm.
2, at both sides, structural jointing position fluting or preformed groove, groove width determines according to adhesion strength conditions of demand,
General every side 20～25cm, groove depth determines generally 4～5cm according to protective layer situation.Glue with U-shaped waterstop
The concrete surface of knot should be clean, smooth, must not have laitance coating, bulge, loosen stone, greasy dirt etc..
3, injecting fluid sealant in structural jointing waterstop bottom, fluid sealant should be cleared up dry with concrete binding face
Only, fluid sealant thickness is generally 2～4cm.
4, at concrete surface brushing binding agent, with the sealing platen presses U-shaped rubber fastening band of bonding.Only
Water tape thickness 6～10mm, bond the every side of width 15～20cm.Sealing pressing plate can use plastic-steel or stainless steel,
And corresponding anchor bolt has stayed preformed hole, platen width, thickness according to pitch of bolts, waterstop thickness,
Bonding strength requirement etc. determines, the widest about 5～8cm, thick 6～10mm.After installing sealing pressing plate, use
Rustless steel nut fastens.
5, elastic mortar or rubber powder are filled on waterstop top, such as the multi-functional rubber powder of acrylamide sand grout or reinforcement,
It is answered dabbing with concrete joint portion and rinses well.
6, after the Cement Mortar Used in Capital phase, in its top brushing elastic water-proof coating, as used polyureas, TB-B
Water conservancy project high-performance coatings etc., when requiring higher to hot strength, can add one layer of tire base net bottom coating
Ge Bu.Coating should stride across whole water stopping trough and both sides xoncrete structure bonding, and both sides respectively overlap width about 10cm.
7, during this type sealing longtime running, may be by aging, heat radiation, coating punching mill, the excessive change of structure
The impact of the factor such as shape causes waterproof coating damaged or U-shaped waterstop fracture.Only during waterproof coating breakage, can
First former coating is struck off, mortar surface polishing is rinsed well, be the most again coated with by original design requirement and refresh
Coating.For the fracture of U-shaped waterstop or because replacing when material property degradation cannot be continuing with walks
Suddenly can " 4～7 " takes instead, forward process is replaced by above, i.e. strike off top coat → cut sand
The damaged waterstop of slurry/rubber powder → removal bolt and pressing plate → dismounting and clear up surface → smear adhesive → by
New U-shaped waterstop → installation pressing plate and bolt → fill mortar/glue are pasted in life size and prepared screw-bolt hole position
Powder → brushing new coating.
The present invention applies at concrete surface layer, waterproof requirement is high, adaptive deformation ability is strong, longtime running can
At xoncrete structure parting when replacing etc. requires.
Embodiment described above is merely to illustrate technological thought and the feature of the present invention, its object is to make
Those skilled in the art are it will be appreciated that present disclosure implementing according to this, it is impossible to only with the present embodiment
Limiting the scope of the claims of the present invention, what the most all disclosed spirit was made changes on an equal basis or modifies,
Still fall in the scope of the claims of the present invention.
