2.1.1 the thickness, specification and model of aluminum alloy door and window profile shall meet the design requirements and shall be provided with factory certificate.
2.1.2 the hardware fittings used for aluminum alloy doors and windows shall match the model of doors and windows. The parts, accessories and fixings used should be stainless steel. If other materials are used, anticorrosion treatment must be carried out.
2.1.3 the anti-corrosion materials and thermal insulation materials shall meet the requirements of the drawings and shall have the factory certificate.
2.1.4 the medium cement sand of No.325 or above shall be prepared as required. Chongqing is a super fine sand area, and small-sized fishstone can be added to the fine sand in proportion.
2.1.5 the connecting iron feet and plates fixed to the structure shall be prepared according to the specifications required in the drawings. And do a good job in anti-corrosion treatment.
2.1.6 the specification and model of the welding rod shall be consistent with the welding parts, and the factory certificate shall be provided.
2.1.7 the variety and model of caulking material and sealing paste shall meet the design requirements.
2.1.8 anti rust paint, iron yarn or aluminum yarn, yarn pressing bar, etc. shall meet the design requirements and have the factory certificate.
2.1.9 the specification and model of the sealing strip shall meet the design requirements, and the adhesive shall match the material of the sealing strip and have the factory certificate of the product.
2.1.10 main machines and tools are aluminum alloy cutting machine, electric hand drill, round file, semicircular file, cross screw driver, scriber, iron foot, compass, steel ruler, steel ruler, steel ruler, drill, hammer, spade, trowel, bucket, water brush, electric welding machine, welding rod wire, mask, welding rod, etc. 2.2 operation conditions 2.2.1 the structure quality reaches the qualified standard after acceptance, and the handover procedures are handled between the types of work.
2.2.2 snap the window center line and horizontal line of 10.5cm according to the size shown in the figure. The in and out line from the window to the external wall is called three line control of the external wall doors and windows, so as to correct whether the size and elevation of the door and window openings meet the requirements of the design drawings. If there is any problem, it should be chiseled in advance.
2.2.3 check whether the position of connecting iron feet on both sides of aluminum alloy doors and windows is consistent with the position of reserved holes on the wall. If there are problems, deal with them in advance and clean up the impurities in the reserved holes.
