Description

Sealing facing and implementation method thereof that masonry structure is used

The present invention relates to the sealing facing that a kind of masonry structure for contain fluid uses and the implementation method of this facing.

Supply the sealing of the pond shape structure of contain fluid, because pool wall might suffer the influence from mechanics, heat, chemistry or earthquake, and the formation risk of crack is arranged, so be difficult to guarantee durable.So, in concrete wall since concrete expand, the expansion of cage of reinforcement, concrete solidification shrinkage is perhaps also because move on ground or bearing framework displacement and crackle might occur.

Up to now, the sealing of masonry structure thing is by an only top layer directly being fitted on the pool wall and guarantee.This is for example under the situation of swimming pool, generally is to adopt sealing ceramic tile veneer to cover.But in view of the ceramic tile veneer does not in fact more almost have elasticity, therefore, when bearing ftractureed, the distortion that just can not absorb bearing itself cracked to cause the ceramic tile veneer.

Another example for people build in chemical products storage bottom usually so that the chemistry of concrete product retentio basin of these chemical products occurs collecting under the seepage situation at storage.Usually, sealed, be covered with in the inside in pond and for example be the fibrage of fiberglass packing, and make by means of resin and to carry out adhesive aggregation between the fibrage for making these concrete retentio basins.Yet so a kind of facing is a rigidity or semirigid, and if a large amount of tensile stresss or flexural stress be applied on the pool wall, just might crack.On the contrary, a kind of pliable and tough facing of chemically-resistant can cause degenerating of sealing.At that time, contaminated liquid then permeate by facing crackle then concrete may soak into the liquid of this pollution.Usually must carry out a large amount of work to remedy the shortcoming that causes therefrom.But, although people adopt various preventive action commonly, always in concrete, exist the vestige of polluted product.Thereby form the boundary material between product rise and etch novel sealing facing and the masonry.

The present invention makes every effort to remedy this shortcoming from the notion of principle, and this notion is to make bearing and sealing facing to break away from.

According to facing of the present invention, it is characterized in that it has sandwich, comprise an extexine of making by encapsulant that is used to be coated on the works wall to be sealed, parallel with extexine and allow with works in the contacted endosexine of making of liquid that holds by encapsulant, and of being placed between two top layers is deformable sandwich, and this is sandwich guarantees the adhesive aggregation on two top layers and absorb to tend to the stress that tradition is delivered to the endosexine by extexine.

Therefore, when having crackle to form on the works wall, elongation stress then is applied on the external seal top layer.These elongation stresses are by the sandwich compressive stress that is applied on the endosexine that is transformed into of deformable.Cause thus, even the extexine that contacts with the works wall has produced crackle, the endosexine can not suffer any damage.

Can realize double seal according to facing of the present invention: first sealant is realized on the works wall, say generally and that if during the not a large amount of change of the size of wall, sealing is enough fully, and second sealant contacts with liquid, constitutes the bearing surface of a low shear stress.

Extexine is to adopt the resin of wrapping up in than short fiber (for example making the 5-6 centimeter length fiber of fiberglass packing) to realize.

For the endosexine, it is by one deck of resin impregnation or which floor natural or synthetic continuous fibre, such as fabrics such as serge type, taffeta types, and realize.Because the length of fiber is long, can guarantee the good transfer of stress, the absorption mechanical stress that these fibers can be preferable.

The endosexine is advantageously covered by a cover that strengthens with short fiber, thereby has constituted sealing barrier.Ratio as fiber in the cover changes by the volume ratio between about 20-40%.In fact, the influence of cover may be interpreted as when being wrapped with the resin polymerization of fiber, resin stands to shrink and produced many small channel on the surface, top layer that contacts with matrix, if on the endosexine, do not cover cover, contraction by resin in the time of just might working as resin crosslinks causes forming long little raceway groove, and consequently the endosexine has seal defect.Because cover contains short fiber, thereby formed the little raceway groove of the capillary weak point of restriction.

Facing is sandwich can be made up of the honeycomb structure that for example is made of polypropylene, and it has repellence for the extruding force that is orientated by honeycomb shaft, but is deformable for the parallel shear stress that puts on two top layers.

Facing can be at the scene with extexine by spraying or coating be deposited on the works wall, then, the sandwich of an ojosa of fitting, and deposition endosexine and cover and realize, but also can realize by the assembling on the spot of the prefabricated panelling that is about to use.

Other advantages of the present invention and feature can contrast accompanying drawing and read the description of the following specific embodiment and understand it, wherein:

Fig. 1 is a coagulation upper storage reservoir sectional view of spreading the facing plate according to the present invention;

Fig. 2 is the larger proportion chi view of the A part of Fig. 1, and;

Fig. 3 is the part of facing plate and the phantom drawing of representing the broken section of cellular type core.

Pond shown on Fig. 1 10 fills or is used to hold arbitrary liquid such as water or liquid carbon oxygen fuel.Pool wall is covered by thick layer of concrete 12, when this layer of concrete 12 any crackle do not occur, just can guarantee the excellent sealing of this layer of concrete.But as described above, crackle can be owing to the rising thereby occur of many types, and liquid can pass crackle and infiltrate in the concrete.Up to now, people attempt to correct this shortcoming and the sealing facing that uses still has limited usefulness, because finally still crack.

According to the present invention, the inwall in pond 10 is covered by sealing panelling 14 as shown in Figures 2 and 3.This panelling has sandwich construction and has the inner and endosexine 18 parallel with extexine of 16, one turn pool in external seal top layer that is fitted on the concrete wall, and has a deformable that is connected with two top layers sandwich between two top layers.

Endosexine 16 can contact merely with concrete wall, but also can closely stick on the concrete wall.It is to realize by the resin of the short fiber that is wrapped with the 5-6 centimeter length (for example making fiberglass packing).This resin can be polyester-type or epoxy type, polyurethane-type or phenol aldehyde type, under pure state, use or be filled with under all kinds reinforcing material state and use, for example adopt be short fiber shape, sheet or granular glass, carbon or " KEVLAR(Kevlar; Fanglun 1414; also claim fiber B, merchant's name, US-built-annotation of translation) etc. reinforcing material.

Endosexine 18 can by be rolled in extexine be that the netted structure of long fibre in the resin of same type or non-same type is formed.As long fibre, people use for example fabric of glass rove type, serge type or taffeta type etc.Extexine itself also can be covered by the cover 22 with short fiber (for example making fiberglass packing) resin, and this cover is intended for sealing barrier as mentioned above.

Panelling sandwich 20 has a kind of honeycomb structure of variable thickness, is for example made by polypropylene, and its advantage is a stay-in-grade, because it can not corroded by chemical agent, thereby can avoid capillary rising phenomenon.But special owing to sandwichly have a deformability, and can guarantee separating of endosexine 18,22 and extexine 16 by the elongation stress that absorbs described wall, thus separate with concrete wall.

Facing can be at the scene by resin and glass fiber bed course being sprayed or being coated on the concrete structure wall, then, place the sandwich of an ojosa, then, by injection or coating and applying resin bed and long fibre layer are last, the injection of carrying out cover is achieved.The number of long fibre and short fiber layers is to change along with required mechanical strength.

Facing also can be realized by means of prefabricated panelling, is delivered for use by factory, therefore only needs assembling on the spot.

Self-evident, the present invention not only is confined to concrete works, and it also is applicable to the surface (for example gypsum, surface of clay etc.) that might form crackle and need not change.
