ã€China Aluminum Industry Network】 1.Aluminum doors and windows for broken bridges shall be processed in the factory and shall not be produced at the construction site. Doors and windows shall be made in accordance with the design and the requirements for the installation and acceptance of aluminum alloy doors and windows. The aluminum alloy door and window frames shall be insulated from heat. The installation of solid doors and windows should be pushed and pulled, flexible opening, there should be drain holes at the window sill, and limit devices should be set. Fasteners should comply with the relevant technical regulations; hardware models, specifications and performance should comply with the provisions of the current national standards.
2. The drainage hole on the sliding window chute should be processed according to the principles of the inner and outer fan inner holes to ensure the sealing performance of the doors and windows, especially the sliding door with horizontal horizontal top.
3, before the assembly of aluminum doors and windows broken bridge, should remove the end processing burrs, end nodes and profile joints must take waterproofing and other sealing measures to prevent structural water seepage.
4. Hidden frame window structure assembly assemblies must be made and maintained in a clean room.
It is necessary to remove dust, oil stains, and other contaminants from the glass and aluminum frame surfaces with a solvent; every clean of one component or piece of glass should be replaced by a clean dry cloth; the solvent should be poured onto the cloth, and the cloth must not come in contact with the solvent bottle mouth. The glue must be full and no bubbles or leakages should occur. The surface of the glue joint should be smooth and smooth; the remaining glue that receives the glue joint must not be reused.
Aluminum alloy door and window installation
(1) Installer:
The window frame is in place → the frame is fixed → the gap is filled → the hardware fittings → the safety glass → the glue, and the cleaning.
(2) Construction points:
a. When installing the window frames on each floor, horizontal and vertical lines shall be pulled, and the layers shall be level and up and down.
b. When the window frame and the wall are fixed, the upper frame is fixed first, and the frame is fixed at the rear and fixed by plastic expansion bolts.
c. The inner cavity of the expansion joint between the frame and the hole is filled with closed-cell foam, elastic material such as foaming agent, and the surface is sealed with sealant.
(3), heat insulation aluminum alloy doors and windows installation process:
A, doors and windows must be installed firmly, the number of embedded parts, location, buried connection method must meet the design requirements, fasteners used to fix each reinforced steel shall not be less than 3, the spacing should not exceed 300mm, from the end of the steel section Should not be greater than 100mm; Reinforced steel, fasteners and hardware except stainless steel, the surface should be treated by corrosion-resistant coating.
B. Doors, windows, and glass shall be installed after the wall wet work method is completed and hardened. Doors and windows shall be reserved by the reserved hole method reserved for the hole; when the doors and windows are installed, the ambient temperature should not be lower than 5°C;
C. When the window and wall are fixed, the upper frame should be fixed and the frame should be fixed afterwards:
Concrete holes should be fixed with shot screws or plastic expansion bolts;
The hole in the brick wall shall be fixed with plastic expansion bolts and shall not be fixed at the brick seams;
Holes with embedded iron fittings shall be fixed by welding, or the fastener holes shall be punched on the embedded parts according to the specifications of fasteners, and then fixed with fasteners;
d. When installing the combination window, set the embedded part or reserved hole to the corresponding position of the joint material in the opening of the window. The connection between the material and the hole:
The connection between the ramming material and the concrete lintel or column shall be provided with embedded iron pieces, which shall be fixed by welding, or the fastener shall be used to press the fastener holes on the embedded parts, and then fixed with fasteners;
When the ramming material is connected with the brick wall, the two ends of the ramming material should be inserted into the reserved hole first, and then be fixed and fixed with a C20 fine stone rake;
The two window frames shall be snapped with the ramming material and clamped with fasteners in both directions. The spacing shall be ≤ 400mm. The gap between the end of the fastener and the split material and the window bar is sealed with a sealing strip;
e. When the doors and windows are connected to the wall by the embedded wooden brick method, the wooden bricks should be treated with anti-corrosion;
f. The inner space of the expansion joint between the window frame and the hole should be filled with closed-cell foam, foamed polystyrene, and other elastic materials. The surface is sealed with a sealant. For projects requiring high insulation and sound insulation, appropriate insulation and sound insulation materials should be used.
g. The surface of windows and doors is clean, free from scratches, bumps and rust; the surface of coating is smooth, even and uniform in thickness, and there is no air hole; it is forbidden to install scaffolds or heavy objects on door frames, fans, gongs, and it is prohibited to step on the windows. Frames, sashes, or windows; surfaces of doors and windows stained with oil, etc., should be cleaned with water-soluble detergents, and should not be scrubbed with harsh or corrosive chemical liquids.
