Abstract
The utility model relates to a waterproof strip for repairing cement roofs, the strip-shaped carcass of which is made of knitting cloth; the outer surface of the carcass is coated with waterproof paint; the inner surface of the telescopic gap in the middle part of the carcass is coated with sealant. The utility model solves the problems of the prior art of poor temperature resistance, easy burst, easy desquamation, inconvenience in use, etc. The utility model provides a waterproof strip which has the advantages of firm adhesion, good waterproof performance and long service life, and is free from environmental influence, and can be completely pasted along natural clefts.
Description
The utility model relates to a kind of cement roof maintenance waterproof bar.
Concrete component be a kind of waterproof construction form of roofing supporting member and the two unification of waterproof from water-proof roofing, at present, the roofing in house, China rural area be exactly mostly on concrete floor covering one deck concrete from water-proof roofing, this water-proof roofing very easily produces the crack.Existing method for maintaining mainly is to adopt waterproofing unction or clay to pile seam, or adopts a cloth two oil, two cloth, three oil to paste seam, and its temperature tolerance is poor, and when the crack changed because of warm, wet or the drying shrinkage of creeping, heap seam or subsides seam thing promptly can break away from basic room, and cost is higher.Adopt epoxy resin or hydrochloric acid cement mortar perfusion crack, though cost is lower, when environment temperature, humidity etc. changed, easier making repaired potting compound and the disengaging of basic room.Adopt sealing compounds such as Polyurethane, poly-sulphur, organosilicon, involve great expense, not only still have caducous phenomenon, but also easily split once more.Adopt natural rubber or elastomeric waterproof bar, only limit to the repairing in well-behaved cracks such as straight line, and can not move towards naturally to lay with the crack, limitation is big, uses inconvenience, and has easily aging or the high problem of cost.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of external environmental conditions such as temperature, humidity that are not subjected to influence, and can move towards complete stickup along dry, bonding firm, difficult drop-off, operation, easy to use, lower-cost cement roof maintenance waterproof bar.
The purpose of this utility model can reach by following measure:
A kind of cement roof maintenance waterproof bar comprises banded carcass 2, and its special character is, the external surface of described carcass 2 is provided with water-repellent paint layer 1, the middle part of described carcass 2 is shrinkage joint 5, and the inner surface at shrinkage joint 5 is provided with one deck fluid sealant 3, and described carcass 2 inner surface both sides are respectively adhesive rim 4.
Convex or the concavity of being convenient to form the shrinkage joint pleat can be set on the shrinkage joint 5 of the present utility model crease 6.
Can be provided with on the shrinkage joint 5 of the present utility model the concave, convex of being convenient to form the shrinkage joint pleat alternate crease 6.
The accompanying drawing drawing is described as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2,3 is respectively the utility model and has the structural representation of creasing.
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, the utility model mainly is made of carcass 2 and fluid sealant 3 and the water-repellent paint layer 1 of being located at its inner surface and external surface respectively.Carcass 2 is a ribbon, is good to adopt knitted polyester, also can adopt better, anti-tear other clothes that draw of elasticity such as knitting cotton.On the whole surface of carcass 2, be coated with one deck water-repellent paint layer 1 thinly, water-repellent paint layer 1 is to adopt elasticity and extensibility all good, tension and tearing toughness height, have better oil resistant, wear-resisting and certain acid resistance, fire-retardant, the environment temperature is become adaptable polyurethane waterproof coating into good, also can adopt ageing-resistant water-repellent paints such as neoprene, acrylate.Behind spraying water-repellent paint layer 1 on the carcass 2, easily appearance, setting, the setting back is difficult for restoring, thereby can be behind water-repellent paint layer in the carcass 2 surface sprayings, on its shrinkage joint 5, be provided be convenient to form in the installation shrinkage joint crease 6, creasing 6 can be provided with one, two or many, crease 6 can by protrudingly crease 7, recessed crease 8 or alternate the creasing of concave, convex form, the shrinkage joint 5 of its formation promptly has one or more pleats, sees Fig. 2～3.Be not provided with on the utility model and crease at 6 o'clock, the shape at its shrinkage joint 5 can form a kind of natural projection or the alternate pleat of concave, convex in construction is pasted.5 places, shrinkage joint in carcass 2 inner surface middle parts are provided with fluid sealant 3, and fluid sealant 3 can impose on the position at shrinkage joint 5 that certain pressure is coated on carcass 2 with the rubber dermatotome, and it is good infiltrating in the carcass 2 with fluid sealant 3 parts.Fluid sealant 3 is to adopt temperature range big, and pliability and fatigue durability are good, and adhesion is strong, elongation per unit length is big, corrosion-resistant and aging, the organic silicon rubber fluid sealant with good stripping performance is good, also can adopt fluid sealant for construction such as poly-sulphur sealing compound, Polyurethane sealing compound.Fluid sealant 3 is mainly used in further sealing, and its stripping performance can make shrinkage joint 5 keep good telescopicing performance simultaneously.During use, coat the glue that is adhesively fixed earlier on the adhesive rim 4 on both sides, roofing crack or carcass 2 inner surface both sides, make shrinkage joint 5 be positioned at top, roofing crack, the waterproof bar is adhesively fixed along fracture strike to get final product on roofing.
The utility model compared with prior art has following advantage:
1, has good compliance. Can naturally move towards intactly to paste and need not to disconnect anti-with roof cracks The water bar.
2, elasticity and good-extensibility, tension, tearing toughness height.
3, corrosion-resistant, ageing-resistant, fatigue durability is good; Oil resistant, wear-resisting, acid and alkali-resistance, sea water resistance; To ring Border temperature, humidity change strong adaptability, and Applicable temperature is interval big.
4, bonding force is strong, long service life. Heat expansion, shrinkage do not have impact to firmness.
5, good waterproof performance, and have preferably anti-flammability.
6, simple in structure, easy to use, cost is low.
