How to use stop watercolor coating

Seam welding of stop water color coated board, the overlap length of water stop coated board is 50mm. The welding seam color-coated board should be welded twice, leaving a 2mm weld seam at the joint. For diyi welding, spot welding should be done at both ends of the middle, and then welding from the middle until welding. Then apply welding from the lower end to the middle, and immediately break the coating with a welding hammer after one time is completed, and check for blisters. Repair welding should be carried out where welding is lacking. The secondary welding should start from the lower end. The shear angle adopts T-shaped or 7-shaped welding and double-sided welding.

1. The water-stop painted board part (except the ramp part): The water-stop painted board should be placed in the outer wall with the curved surfaces at both ends facing the water surface. After the level of the waterstop of the color-coated board is determined, measure it according to the building height control point, and pull the opening of the waterstop of the color-coated board to make it smooth.

2. Use steel bars to fix the thickness of the color-coated plate, and use oblique steel bars to fix it on the top mold rod. The water-stop steel strand should be welded with the short steel bars in the lower hole, and the support thickness is a color-coated plate, and the length is subject to the thickness of the steel bar mesh of the concrete color-coated plate wall. It should not be too long to avoid the formation of leakage channels along the short steel bars.

3. Water color coating requirements: the welding seam bixu is round, no slag, and the height of the welding seam meets the requirements; the welding seam is free of trachoma, burns and undercuts; the thickness of the seam is the color-coated board invisible deformation and warping, and the water color coating The board position and the height are correct.

4. Setting of positioning ribs for stop watercolor coating board: weld φ10 steel bars along both sides of the stop watercolor coating board, one end welded to the stop watercolor coating board, and the other end welded to the shear wall beam, the steel bars are placed vertically on the main reinforcement; spacing between positioning rods It is 1000 mm, symmetrically arranged on both sides.

How to fix the waterstop with the watercolor coating?

In general large-scale projects, due to continuous pouring failure or temperature change caused by thermal expansion and contraction of concrete components, the watercolor coating should be blocked. Settlement joints and deformation joints. In order to prevent water leakage, these joints bixu are installed with rubber stop water paint plates.

The fixing methods of water stop tape and color-coated plate thick belt include: steel bar fixing, special fixture fixing for water-stop painted plate, lead wire fixing, mold fixing, etc. If it is worn, you can choose the waterstop side installation area, and other parts shall not be damaged.

Water-stopping rubber coating is a basic project, currently mainly used for pouring concrete construction joints, deformation joints and concrete structures, such as underground facilities, tunnels, culverts, aqueducts, color-coated dams and liquid storage structures, etc. . , Sometimes need to be combined. The role of two-component polysulfide building waterproof sealant.
