Henan roof aluminium alloy Waterproof strip, Henan roof aluminum alloy deformation joint construction,
It can be divided into: floor expansion joint , expansion joints of exterior wall, interior wall, ceiling and ceiling, and roof.
2) According to the characteristics of the location where the expansion joint is used, it can be divided into plane type and corner type.
3) According to the structural characteristics of the expansion joint device, it can be divided into: metal cover plate type, metal lock type, single row flush type, double row flush type and rubber flush type.
4) It can be divided into load-bearing type and anti-seismic type according to the special requirements of the use function.
Practice of deformation joint of exterior wall building
1. Before installation, carefully check whether the notch meets the requirements of the product. Excess parts need to be chiseled, damaged parts need to be repaired, and too deep and too wide parts need to be reinforced with straight bars to ensure the straightness and firmness of the notch.
2. During installation, take the center of the deformation joint of the external wall building as the base point, set out on both sides according to the selected model and the requirements of the atlas, determine the location of the fixed aluminum alloy base, and then use the same method to determine the expansion Bolt The position and spacing of shall meet the requirements of installation drawings.
3. Install the fire stop belt according to the actual requirements, apply special base adhesive on the base layer at the joint side of the gap and on both sides of the water stop belt, lay the water stop belt flat on the concrete base layer, and compact it with corresponding tools. When the water stop belt is fixed at the joint between the two sides and the concrete, there shall be no bubbles or openings.
4. Put the aluminum alloy base into the notch, adjust the design elevation to make the longitudinal slope, cross slope and decorative surface consistent, and then fix the aluminum alloy base with expansion bolts.
5. The sliding rod shall be arranged according to the designed spacing for preliminary fixation. If the card lock type is selected, the seam shall be split in the middle to fix the aluminum alloy base. After the panel is covered, it shall be fixed with bolts. After the installation, the surface cover plate of the deformation joint of the external wall building shall be connected with the Floor The longitudinal slope and cross slope shall be consistent.
