Detailed description of the invention
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings and tool
This utility model is described in further detail by body embodiment.
As illustrated in fig. 1 and 2, repair structure to be formed by 4 layers: elastomeric isolation layer+(bottom surface epoxy coating+glass fibre belt+surface ring
Oxygen coating), and (bottom surface epoxy coating+glass fibre belt+surface epoxy coating) constitutes confining bed；
Elastomeric isolation layer preferentially selects polyurethane coating, one-component polyurea/polyurethane coating, it is possible to select acrylic compounds to be coated with
Layer material, it is desirable to having preferable elasticity, and have certain thick performance that is coated with, painting brushes one times and can reach more than 500um, can realize mixing
The good covering on solidifying soil surface；
Epoxy coating in confining bed requires to have following characteristics: 1. excellent toughness, and has the extension at break of more than 5%
Rate；2. good dried noodle and wet surface adhesive property is had with concrete；3. excellent thick painting property, can be at facade primary coating 1mm
Above；4. excellent isolating and protecting performance, acid and alkali resistance, the corrosion of salt.Preferential employing YEC epoxy barrier material；
Glass fibre belt in confining bed can use plain weave medium-alkali glass fibre band or cloth, has preferable resistance to corrosion；
Elastomeric isolation layer, with crack as center line, is brushed along both sides, crack, and the purpose of elastomeric isolation layer is to increase glass-epoxy
Coating system causes deformation range during folding in crack due to the factor such as blast, temperature；Brushing width is with the width of crack folding
Degree determines.The percentage elongation of such as glass is about 3%, and the elongation range of 3cm can bear the crack folding of 0.9mm, this folding
Scope is the most enough, so generally can be along the elastic coating of crack coating 3cm.If actual crack
Folding is relatively big, can suitably increase the width of elastic coating；
The thickness of elastomeric isolation layer typically requires more than 500um, and owing to concrete surface has certain roughness, this is thick
Degree can meet covering, insulation request, not adversely affects higher than this thickness；
The thickness of the two-layer epoxy coating in confining bed is desirable that more than 1mm, so can reach excellent isolation effect,
And beneficially thorough impregnation, parcel glass fibre belt；
The thickness requirement 0.15mm-0.20mm of the glass fiber tape in confining bed, had both met mechanical requirements, the most beneficially epoxy
The dipping of material, parcel；Width requirement exceeds elastomeric isolation layer every limit more than 5cm, generally can use 15cm width
Glass fibre belt；
The coating width of two-layer epoxy coating should be more slightly wider than glass fibre belt, and at least every hem width goes out more than 2cm.
Compared with prior art, this utility model has the advantages that
1, the cooling tower concrete surface Crack Repairing structure that this utility model provides, uses elastomeric isolation layer and toughness to prevent
The system of sheath, i.e. avoids elastomeric material and easily comes off, and turn avoid rigid material near crackle under big strained condition
Problem of Cracking, has crackle and closes protection effect reliably.
2, due to the factor such as blast, temperature, the crack of concrete surface can produce small opening and closing campaign, uses coating material
Material fracture is closed, and prevents Korrosionsmedium from passing through crack and enters concrete, is to improve reinforced concrete structure durability
Effective ways.The closed material used at present is generally divided into two classes, and one is highly elastic material, and one is rigid/semi-rigid
Material.Practice have shown that, elastomeric material easily produces the problem of coming off, and rigid/semi-rigid material will due to local near crack
Bear the biggest strain, easily produce problem of Cracking, thus lose protective action.To this end, the cooling tower that this utility model provides
Concrete surface Crack Repairing structure, have selected elastomeric isolation layer and the material system of toughness confining bed, closed material layer with
Being pre-formed the elastomeric isolation layer of one fixed width between cast concrete base, its modulus is far smaller than closed material layer, sealing coat with
Relatively weak bonding force is there is between closed material layer.In the moving process of crack, strain will be dispersed in the envelope of relative broad range
Close in material layer, thus avoid the cracking destruction of closed material layer, it is ensured that sealing effect.
3, the cooling tower concrete surface Crack Repairing structure that this utility model provides, sealing coat uses the elasticity being coated with brush-type
Material, elongation at break more than 200%, more than intensity 10MPa, brushing more than thickness 500um.Have an advantage in that convenient construction,
Sealing coat itself also has certain protective action.
4, the cooling tower concrete surface Crack Repairing structure that this utility model provides, as the epoxy coating material of confining bed
Material has good toughness, the percentage elongation of more than 5%, the intensity of more than 15MPa, not only has the most bonding with concrete, and
And phenomenon will not be fallen off.There is good Corrosion Protection and excellent thick painting property simultaneously.
5, the cooling tower concrete surface Crack Repairing structure that this utility model provides, the effect of glass fibre belt is the increase in envelope
Close the rigidity of layer, it is to avoid confining bed disengages and issuable obscission with sealing coat, and disperse the effect of strain concentration.
