③ SBS coiled material waterproof system can effectively avoid the phenomenon of “zero extension fracture” of waterproof layer caused by structural deformation because of its high-strength matrix.
Generally, the construction method of external prevention and external sticking is used for side wall waterproofing.
What needs to be prepared before construction? 1、 Base course preparation ① the base course is solid, flat, dry and clean.
④ The wall shall be polished and leveled, and the wall shall be dry and clean.
How to choose waterproof materials for side wall waterproofing? Common waterproof materials for side wall waterproof include modified asphalt waterproof coiled material and self-adhesive waterproof coiled material.
After the large surface paving of coiled material is completed, it is compacted with a pressing roller.
② the plane and elevation joints, turning points, internal and external corners, pipe roots, etc.
② Base course cleaning tools: blade and blower.
4.
The width of the lap edge of coiled material is ≥ 100mm3.
④ Coil construction tools: wire snapping box, wallpaper knife, hot-melt spray gun and pressing roller.
The metal strip is sealed with asphalt sealant source: Shaanxi PU waterproof (this paper is.
③ The waterproof construction can be carried out only after the components out of the base are installed.
The width of the additional layer of the base plate rotating side wall is ≥ 300mm2.
What are the links of side wall construction? Treatment of base course → painting of base course treatment agent → treatment of detail nodes Paving additional layer → positioning and snapping line of coiled material → paving self-adhesive coiled material on the large surface → fixing the coiled material end → sealing the edge with sealing paste → quality inspection of waterproof layer → the following part of the construction protective layer is the most important part in the construction.
The selection of SBS modified asphalt waterproof coiled material for construction has the following advantages: ① material advantages, better extensibility and mechanical properties, and the ability to resist the damage of residual hard objects in the base course and crack damage in the base course are higher than other coiled materials.
The top of coiled material is fixed with a metal pressing strip 5.
We take SBS modified asphalt waterproof coiled material as an example.
② The construction method is more flexible.
③ Brushing tools for base treatment agent: rolling brush and brush.
Firstly, an enhanced waterproof coiled material is laid on the base plate cushion and the main body of the side wall structure, and then a large area of waterproof coiled material is laid on the main body of the side wall structure.
1.
2、 Preparation of construction materials and machines ① main and auxiliary materials: waterproof coiled material, base treatment agent, sealing material, closing strip and screw, additional layer coiled material, etc.
shall be made into uniform, flat and smooth rounded corners, and the arc radius shall not be less than 50mm.
