Abstract
The utility model discloses a kind of concrete panel crack surface treatments, it is characterised in that：Separation layer (2) is provided with the top of described crack (5), brushing primary coat and waterproof material (3) around described separation layer (2) and described crack (5)；Carbamide paint (1) is coated with described primary coat and waterproof material (3), described carbamide paint (1) bonds with described separation layer (2)；The shortcomings that it overcomes fracture faces processing in the prior art, and the strength of materials is low, bad adhesion, easy to aging, adaptive deformation ability, has the surface treatment for being widely used in rock panel early crack.
Description
Technical field
Concrete slab enrockment technical field is the utility model is related to, is more specifically that a kind of concrete slab splits
Seam surface processing structure.
Background technology
Panel crack is still to deform in one of most common disease of CFRD, particularly later stage " to live
Seam ", the presence in crack not only reduces the ageing resistace and durability of panel, and deeper clefts can cause seepage of dam,
And then threaten dam safety.Panel crack conventional treatment mode is mostly classification processing：Fine cracks are using surface-closed, wide drastic crack
Seam uses surface-closed after chemical grouting, and wherein chemical grouting material is more using epoxy resin, polyurethane etc., surface difference material
It is even more varied, such as mortar, epoxy resin mortar, epoxy mortar, antiseepage cover plate, acrylamide sand grout.But above surface-closed material
The problems such as low bulk strength, loss of properties on aging, weak barrier performance be present.
In recent years, spray polyurea obtains largely as a kind of novel solvent-free, non-contaminated surface sealing paint in engineering
Using.As " a kind of concrete surface protecting structure of hydraulic structure " (patent No. CN201220127691.8) discloses use
Protection structure of the SPUA as concrete surface；" concrete for hydraulic structure member expansion joint or crack water leakage preventing structure "
(patent No. CN200920279118.7) discloses a kind of expansion joint formed using flexible filler and external coating polyurea materials
Water sealing structure.Above polyurea materials are used for the ageing-resistant protection of concrete or the processing of structural joint more, and what is used is mostly that hand is scraped
Polyureas, speed of application is slow, coating layer thickness is uneven.
The content of the invention
The purpose of this utility model is the weak point for overcoming above-mentioned background technology, and proposes a kind of concrete slab and split
Seam surface processing structure.
The technical solution of the utility model is implemented by following measure：A kind of concrete panel crack surface treatment knot
Structure, there is crack on concrete slab；Separation layer is provided with the top of described crack, in described separation layer and described
Brushing primary coat and waterproof material around crack；Carbamide paint, described polyureas are coated with described primary coat and waterproof material
Coating bonds with described separation layer.
In the above-mentioned technical solutions：The width of described separation layer be 1 centimetre, described separation layer using foam adhesive tape,
The flat bar that plastic filler is twisted into.
In the above-mentioned technical solutions：The width of described carbamide paint is 50 centimetres, and thickness is 2-3 millimeters.
In the above-mentioned technical solutions：60 centimetres of the concrete slab of seam week in described crack is cleared up in advance.
The utility model has the following advantages that：1st, the utility model proposes set separation layer in sealing and can be effectively increased polyureas
The ability of coating adaptive deformation in Fracture Deformation, will not be in Fracture Deformation because of the thinning influence anti-seepage effect of coating.2nd, filling
While carbamide paint barrier performance and adhesive property are waved in distribution, the ability for adapting to Fracture Deformation is improved, for the processing of " seam living "
Provide efficient processing scheme.3rd, it can be widely applied to the surface treatment of rock panel early crack.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Carbamide paint 1, separation layer 2, primary coat and waterproof material 3, concrete slab 4, crack 5.
Embodiment
Describe performance of the present utility model in detail below in conjunction with the accompanying drawings, but they are not formed to of the present utility model
Limit, it is only for example, while will become clearer and be readily appreciated that the advantages of by illustrating the utility model.
Shown in reference picture 1：A kind of concrete panel crack surface treatments, there is crack 5 on concrete slab 4；Its
It is characterised by：The top in described crack 5 is provided with separation layer 2, applied around described separation layer 2 and described crack 5
Brush primary coat and waterproof material 3；Be coated with carbamide paint 1 in described primary coat and waterproof material 3, described carbamide paint 1 with
Described separation layer 2 bonds.
The width of described separation layer 2 is 1 centimetre, and described separation layer 2 is twisted into flat using foam adhesive tape, plastic filler
Bar.
The width of described carbamide paint 1 is 50 centimetres, and thickness is 2-3 millimeters.
60 centimetres of the concrete slab 4 of seam week in described crack 5 is cleared up in advance.
A kind of Face Slab of Concrete-faced Rockfill fracture faces processing structure, including it is arranged on the separation layer 2 of crack sealing
With the carbamide paint 1 being covered on separation layer 2, the separation layer 2 is the not sticking material of band with the reaction of polyureas raw material,
The carbamide paint 1 is spray polyurea, and the brushing of waterproof material and primary coat 3 is carried out before spraying.
All 60cm concrete surfaces 4 will be stitched before crack treatment first to clean out, should be handled if any larger hole.
Then brushing primary coat and waterproof material 3, after basal plane drying, separation layer 2 of being constructed at the top in crack 5, then spray polyurea painting
Material 1, as the preferred scheme of the present invention, the width of separation layer 2 is 1cm, and the width of carbamide paint 1 is 50cm.
The above-mentioned part to describe in detail is prior art.
