Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1, the utility model discloses a waterproof structure of roof movement joint, including first shutoff board 801, second shutoff board 802, by the connecting piece that nut 5 and bolt 6 constitute, waterproofing membrane 3, movement joint filler material 4, waterproof sealant 10, ceramic fibre 7, epoxy 1 and polyethylene 2.

Deformation joints exist among the roof concrete structures 9, and the deformation joint filling materials 4 are filled in the deformation joints. Deformation joint filler material 4 is polystyrene foam, and polystyrene foam is good buffer material, and temperature strong adaptability, no matter how the settlement of ambient temperature and building changes, polystyrene's volume still changes along with the volume change of deformation joint, keeps good bonding effect with the deformation joint, and polystyrene hydroscopicity is little, and water resistance is good, even there is moisture on the upper strata and also can not permeate downwards in getting into the deformation joint, plays water-proof effects.

The first plugging plate 801 is arranged on the upper side of the deformation joint to cover the deformation joint; the second closure plate 802 is located on the underside of the deformation joint and holds the filler material 4 within the deformation joint. The upper end of the bolt 6 is welded with the first plugging plate 801, and the lower end of the bolt 6 passes through the second plugging plate 802 and is fastened with a nut 5 below, so that the second plugging plate 802 does not fall off. The first plugging plate 801 and the second plugging plate 802 are both galvanized iron. The bolt exceeds the part of the second plugging plate, the bolt is not required to be too long, the length is 2-3 cm, and the bolt is high in strength.

The corners of the first plugging plate 801 are caulked with epoxy resin 1, and the top of the first plugging plate 801 is filled with polyethylene resin 2, so that double slopes having an angle of 6 degrees are formed on the plane of the roof (as shown in fig. 2, the double slopes are "" shaped). Two layers of waterproof coiled materials 3 cover the double slopes, each layer of waterproof coiled material extends to the roof surface, and the covering surface of the outer layer of waterproof coiled material is larger than that of the inner layer of waterproof coiled material. The small-angle double-slope self-waterproof structure is favorable for draining external moisture and forms a first waterproof line. The epoxy resin has the characteristics of compactness, leakage resistance, high strength and the like, and simultaneously has good construction workability such as strong adhesive force, normal-temperature operation, simple and convenient construction and the like. The polyethylene resin has excellent acid and alkali resistance, can effectively prevent the corrosion resistance of the galvanized iron sheet, and prolongs the service life of the galvanized iron sheet.

The first plugging plate 801, the second plugging plate 802 and the roof concrete structure 9 are bonded by the waterproof sealant 10, so that a second waterproof line is formed. The waterproof sealing paste 10 is sometimes called waterproof paste, and the waterproof paste has good heat resistance, cold resistance and bonding property, can effectively prevent the looseness between the plugging plate and the roof concrete caused by temperature change, and has good waterproof effect.

The ceramic fiber 7 wraps the lower part of the second plugging plate 802, and bad visual effects generated by the second plugging plate 802, the nut 5 and the bolt 6 are eliminated. Ceramic fiber has good heat preservation and insulation performance, can reduce the influence of external temperature on the deformation joint, and ceramic fiber still has good fire resistance simultaneously, improves the fire resistance of this deformation joint waterproof construction, reinforcing life.

The utility model discloses a waterproof structure of roof movement joint can be under construction according to following step: after the lower side of the concrete structure 9 is coated with waterproof factice 10, a galvanized iron sheet 802 with bolt holes is pasted, and polystyrene foam 4 is filled in deformation joints; the upper layer of the concrete structure 9 is coated with waterproof ointment 10 and covered by galvanized iron sheets 801 with bolts 6, the bolts 6 penetrate through bolt holes in the galvanized iron sheets 802, and the nuts 5 are connected with the lower ends of the bolts 6; the upper layer galvanized iron sheet 801 is caulked by epoxy resin 10 to form a small angle of 5-6 degrees, a polyethylene resin 2 is filled on an extension line of the small angle to form a triangle, two layers of waterproof rolls 3 are attached to the outer side of the large triangle, and each layer of waterproof roll 3 can completely wrap the inner layer of material; the lower part is wrapped by ceramic fiber 7 to form a nut 5, a bolt 6 and a galvanized iron sheet 802. The thickness, angle, length and the like of materials of each part can be slightly adjusted according to specific construction conditions in the construction process, and the principle of 'waterproof first and construction second' is taken as the principle.
