Problems solved by technology

The reason is that firstly, the coiled material is pasted on the seam of the compartment, and the adhesive force between the coiled material and the two sides of the joint is poor and it is easy to degumming. Secondly, the coiled material is frequently pulled and folded on the two sides of the joint, and it is easy to crack and seep. When water and sand penetrate into the caulking ointment, it will affect and destroy the waterproof ability of the oil glue, and eventually lead to water seepage in the sub-compartment joints, such as figure 1 shown

Embodiment Construction

[0012] The construction method of the waterproof covering layer on the sub-compartment joints: first, clean the two sides of the sub-compartment joints before applying water-based asphalt, and fill the sub-compartment joints with caulking ointment (slightly higher than the plane by about 1mm), and then Brush the 30cm wide water-based asphalt paint (thickness: 0.2-0.4mm) thinly on the joints of the bins, and evenly coat a layer of 0.7-1.0mm thick water-based asphalt paint after drying. Before the second layer of water-based asphalt paint is completely dry, lay the plastic cavity flat and paste it in the center along the slits of the bins, cover it with glass mesh cloth and evenly brush a layer of water-based asphalt paint with a thickness of about 0.7-1.0mm. After it is completely dry, apply a layer of water-based asphalt paint with a thickness of about 1.0-1.5mm evenly, so that the construction of the waterproof covering layer on the joints of the sub-bins is basically complete...

Abstract

The invention is a waterproof processing method of storehouse-separating seam of building roof, concretely, coating a water pitch waterproof layer on the seam, and spreading a plastic cavity layer and glass mesh cloth in the coat, thus enhancing anti-cracking performance of waterproofing plaster coat. It is convenient to construct and has an ideal leak-proof effect.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing, and in particular relates to a waterproof and anti-seepage treatment method for sub-storey joints on the roof surface of a building. Background technique [0002] Generally, PVC ointment or batch caulking ointment, rubber fillets are used to fill the joints on the surface of the roof, and then waterproof membranes are pasted on the joints as anti-seepage means. However, due to thermal expansion and contraction, separation The concrete slabs on both sides of the warehouse joints are relatively active, and most of the warehouse joints exposed to the sun and rain will soon see water seepage. The reason is that firstly, the coiled material is pasted on the seam of the compartment, and the adhesive force between the coiled material and the two sides of the joint is poor and it is easy to degumming. Secondly, the coiled material is frequently pulled and folded on the two sides of the joi...
