For the above-mentioned water leakage problem, people's existing roof leak-proof means the most common way has two kinds: the one is to re-spread one deck of leak-proof material on the roof, such as paving one deck of cement sandstone, not only waste material, also can increase The pressure on the top surface of the roof, and more importantly, the leak prevention has not achieved the desired effect. The disadvantage of this method is that the service life is short, generally 3 to 5 years; the second is to repair the cracks on the roof surface with boiled asphalt , the defect of this method is that the asphalt can only cover the shallow part of the cracks on the roof, and it is difficult to penetrate into the deep cracks, and the asphalt in the shallow cracks will be brittle, weathered, delaminated and cracked due to wind and sun. , rainwater will leak along with the original cracks, and the surface of the repaired roof is not uniform, not neat, and the amount of repairs is large

Embodiment Construction
[0027] The present invention will be further elaborated below in conjunction with accompanying drawing, wherein, the direction of the present invention is with figure 1 as standard.
[0028] Such as Figure 1 to Figure 6 As shown, the leakage repairing glue injection device 1 adopted for implementing the leakage repairing method for building cement platform roof cracks of the present invention comprises a rubber cartridge holder 11, a rubber cartridge 12, a rubber cartridge cover 13 and an air pump, wherein the leak repairing device 1 is vertically arranged , the rubber cartridge fixing seat 11 is arranged at the bottom of the rubber cartridge 12, and the rubber cartridge fixing seat 11 and the rubber cartridge 12 are detachably connected in an airtight manner through threaded cooperation. The glue port 111 and the glue cartridge 12 are used to store the prepared and mixed AB glue. The glue cartridge 12 is made of transparent plastic material with high compressive strength, a...

Abstract
The invention discloses a building cement platform roof crack leak repairing method, clear water is sprayed to the roof so as to find a crack position, and the crack position is marked; an adhesive AB which is formed by mixing an adhesive A and an adhesive B according to the weight ratio of 1:1 is uniformly scraped into the crack from a crack gap in the lower surface of the roof, and a first adhesive AB plugging layer is formed after the adhesive AB is fully hardened and solidified; an adhesive AB which is formed by mixing the adhesive A and the adhesive B according to the volume ratio of 1:1 is uniformly scraped into the crack from a crack gap in the upper surface of the roof, a second AB plugging layer is formed after the adhesive AB is fully hardened and solidified, at the same time, overflow end ports are reserved in the two ends of the crack in the length direction, and an adhesive injection end port is reserved in the middle position of the crack in the length direction; an adhesive AB which is formed by mixing the adhesive A and the adhesive B according to the weight ratio of 3:1 is injected into the crack in the roof by an adhesive injection device under the high temperature exposure weather condition. According to the building cement platform roof crack leak repairing method, the leak repairing construction efficiency is higher, the leak repairing effect is good, and the service life is long.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a leak-trapping method for cracks on the roof of a cement platform of a building. Background technique [0002] Buildings mostly adopt the structural type of cast-in-place reinforced concrete platform roofs, which are prone to cracks and cause water leakage, especially in the rainy season, which will cause roof leakage, soak the walls, and affect living. The reason is mainly due to the change of stress caused by the ground foot or local subsidence, resulting in cracks, and the uneven thermal expansion and contraction of concrete caused by long-term wind and sun exposure. For the above-mentioned water leakage problem, people's existing roof leak-proof means the most common way has two kinds: the one is to re-spread one deck of leak-proof material on the roof, such as paving one deck of cement sandstone, not only waste material, also can increase The pressure on the top surfac...
