the problems which should be paid attention to in the aluminum window bending machine Installation

Date：2013-09-21 Author：zhaoyang Hits：1049

aluminum window bending machine works must be designed for strength design calculations and experiments , as well as profiles based only on standard atlas provided by the manufacturer for the type test report on the fabrication, installation , inspection, this is wrong and even dangerous behavior. Because standard atlas is only a series of sub-grid window type large drawing , drawings did not indicate at that can withstand the load , it is not for the production , installation, acceptance basis. For different series of windows and doors, the state must be the worst affected by the principles of force strength , deflection of checking or testing . Floor doors and windows of the strength and stiffness generally inadequate to deal with one of the columns and beams for the main force to enhance handling . Location of high-rise building height ≥ 30M exterior doors and windows , they should be GB50057 " Building Lightning Protection Design Code " implementation.

Manufacture aluminum window bending machine manufacture of aluminum windows and doors should be carried out in the factory may not be produced at the construction site . Sliding on the slide should be followed within the drainage hole machining outer hole fan , fan bore principles to ensure the sealing performance of windows and doors , especially horizontally oriented transversely sliding tops . Before assembly of aluminum doors and windows should be cleared end machining burrs , end nodes, and junction profiles must take waterproof glue sealing measures , to prevent structural water seepage. aluminum window bending machine structure hidden frame window assembly assembly must purify indoor production and conservation . Must use clear glass and aluminum frame solvent bonding surface of dust , grease and other contaminants ; every cleaning a component or a glass, should be replaced with a clean dry cloth ; solvents should be dumped in the cloth , the cloth is strictly prohibited contact with solvent bottle mouth . Plastic injection must be full , with no bubbles , missing notes, glue seam surface should be smooth ; close glue glue joints I can not be reused.

aluminum window bending machine installation, product protection before installation of window and door openings deal with the shape and position accuracy stakeout check, check number and location of concrete embedded with the design requirements , high-rise window whether the requirement to access mine belt, for the failure part of the construction unit shall supervise the rectification . Oxidation with cement mortar caulking material windows and doors, on the wall should be made before embalmed. In addition to outward walls , the window frames were used on other surfaces with a protective adhesive tape or plastic . Toward the wall may not have adhesive tape or plastic tape exists, the gap junction to avoid water seepage . Doors and windows on the wall with a wooden wedge adjustment position, and then nail fixation, not with nails , wedge fixed . Please supervision units before caulking ( or construction unit ) possible concealed work record, and doors for vertical, horizontal , diagonal be checked , after caulking wooden wedges shall be left in the seam . Fight between the window frame and the wall must be waterproof glue on the wall after drying . If the wall is not dry, dust is not cleaned, the walls and cause the release of water vapor seal failure . Wet work is complete, the installation of glass and sash front , clear protective adhesive tape or plastic band and sash sector dirt.

Project acceptance aluminum window bending machine engineering inspection shall GB50300 " Construction Quality Acceptance uniform standards" and GB50210 " Building Decoration Engineering Quality Acceptance" execution. Aluminum doors and windows of acceptance, acceptance shall be concealed engineering and construction units on the basis of self-qualified . Project acceptance should check the following documents and records : doors and windows production licenses and installation qualification certificates. Engineering design calculations , design specifications , construction , doors and windows three of inspection reports , aluminum doors and windows product quality certification , inspection records hidden works , installation and construction of self-test records and aluminum, glass , sealing materials , hardware accessories, product certification, quality guarantee and site acceptance records, aluminum, safety glass and structural adhesive reinspection report shall also be provided

Important: Aluminum is an active metal , the protective layer is no corrosion damage at capacity , prone to corrosion, shall take the necessary measures to strengthen the protection of the surface profile of the film . Water is the source of corrosion , should prevent rainwater from entering the corrosion resistance of aluminum profiles without cavity .
