Strengthen and improve the specifications and standards of door and window products, and integrate with international standards and certifications. Broken Bridge aluminum doors and windows (entry "Broken Bridge aluminum doors and windows" provided by industry Encyclopedia) solved the problem of heat insulation of original ordinary aluminum doors and windows (entry "heat insulation" provided by industry encyclopedia) and became an inevitable choice for green ecological buildings. Broken Bridge aluminum doors and windows is designed and combined by materials such as profiles, glass, rubber strips, hardware, sill plate and window frame. Broken Bridge aluminum doors and windows is not a simple combination of materials. It adopts structural safety, the overall design optimization of reliability and the selection of different materials are realized. Its design, assembly and installation methods are flexible and changeable, and directly affect various performance indexes, safety and reliability of doors and windows.
The purpose of door and window design is to improve the performance quality of doors and windows. Door and window specifications and standards are the major basis for door and window design. Various properties of doors and windows do not exist alone, and there are more or less mutual promotion or restriction relationships between them, so it is difficult for us to design our doors and windows separately. The wind pressure resistance, air tightness and water tightness of doors and windows are closely related. The wind pressure resistance, water tightness and air tightness specified in GB/T7106-2008 "test and classification method for air tightness and wind pressure resistance of exterior doors and windows of buildings" are all openable field performance in normal closed state, however, wind pressure resistance and water tightness are the resistance under the simultaneous action of wind and rain, and this dynamic change should also be taken into account in the design. The latest Standard GB7106 "classification and detection method of wind pressure resistance performance of building Windows", which is being submitted for approval, adjusted the detection device, modified the detection sequence and detection method, and canceled the air tightness, the classification of watertightness and wind pressure resistance, but it needs to meet the engineering design requirements, etc. The assembly of aluminum alloy doors and windows should be in accordance with relevant technical requirements and specifications, and also depends on the quality of processing equipment and the operation ability of personnel. It is necessary to control the actual operation to control the quality of doors and windows.
Good manufacturing specifications for doors and windows are as follows:
1. Broken Bridge aluminum doors and windows processing and production shall be carried out in the factory, and shall not be made on the construction site.
2. The manufacture of doors and windows shall meet the requirements of design, installation and acceptance specifications.
3, should be installed firmly, push and pull open flexible.
4. There should be a drain hole at the window sill, and a limiting device should be set.
5. The model, specification and performance of hardware shall conform to the current national standards.
6. Sliding window the drainage hole processing on the slide should follow the principle of inner fan outer hole and outer fan inner hole to ensure the sealing performance of doors and windows, especially the horizontal wool tops horizontal sliding window.
7. Broken Bridge aluminum doors and windows before assembly, the end processing burrs should be removed, and sealing measures such as waterproof adhesive must be taken at the end node and the joint of the profile to prevent the structure from leaking water.
8. Assembly parts must be made and maintained in the purified room. The dust on the bonding surface of glass and aluminum frame must be removed with solvent. For every component or piece of glass cleaned, the clean dry clean cloth should be replaced; The solvent should be poured on the wiping cloth, and it is strictly forbidden to contact the solvent bottle mouth; the glue injection must be full, without bubbles or leaks. The surface of the glue-line should be smooth and smooth, and the remaining glue of glue-line should not be reused. Broken bridge aluminum doors and windows.
Installation specifications:
1. Installation procedure: window frame in place & rarr; Frame fixing & rarr; Fill plug gap & rarr; Hardware accessories & rarr; Glass & rarr; Glue and clean up.
2. Key points of construction:
a. When installing window frames on each floor, the lines should be pulled horizontally and vertically, and the levels of each floor should be the same, straight up and down.
B. When the window frame is fixed with the wall, fix the upper frame first, and then fix the frame with plastic expansion bolts.
c. The inner cavity of the expansion joint between the frame and the opening adopts closed-cell foam, foaming agent and other elastic materials fill plug, and the surface is sealed with sealant.
3. Broken Bridge aluminum doors and windows installation process:
a. The installation of doors and windows must be firm. The number, location and embedded connection method of embedded parts must meet the design requirements. The fasteners used to fix each reinforced steel must not be less
3, the spacing should be no more than 300mm, the distance from the end of the steel should be no more than 100mm; Reinforced steel, fasteners and hardware, except stainless steel, the surface should be corrosion resistant coating treatment.
B. The installation of doors and windows and glass should be carried out after the wet working method of the wall is completed and hardened. The doors and windows should be installed by the reserved opening method and the reserved opening method; When the doors and windows are installed, its ambient temperature should not be lower than 5℃.
c. When the window and the wall are fixed, the upper frame should be fixed first, and the rear iron frame should be fixed: the concrete opening should be fixed by fastener or the plastic expansion screw brick wall opening should be fixed by plastic expansion bolts, and should not be fixed at brickwork joints; holes with embedded iron parts should be fixed by welding, or first make base holes on embedded parts according to Fastener specifications, and then fix them with fasteners.
d. When installing the combined window, the embedded parts or reserved holes should be set at the corresponding position of the fitting window.
e. Connection between the splicing material and the opening: the connection between the splicing material and the concrete lintel or column shall be equipped with embedded iron parts, which shall be fixed by welding, or base holes shall be made on the embedded parts according to fasteners, then fix it with fasteners; When the splicing material is connected with the brick wall, insert both ends of the splicing material into the reserved hole, and then fix it with C20 fine stone concrete; the two window frames should be insulation displacement connection with the splicing materials. After insulation displacement connection, tighten them with fasteners in both directions, and the spacing should be ≤ 400mm. The gap between the end of the fastener and the splicing material and the window bar is sealed by sealing strip.
f. When the doors and windows are connected with the wall by the embedded wood brick method, the wood brick should be treated with anti-corrosion.
g. The inner cavity of the expansion joint between the window frame and the opening should be layered and fill plug with elastic materials such as closed-cell foam plastic and foamed polystyrene flame, and the surface should be sealed with sealant. For projects with high requirements of heat preservation and sound insulation, corresponding heat insulation and sound insulation materials should be adopted fill plug.
h. The surface of doors and windows is clean, without scratches, bumps or rusts; The surface of the glue coating is smooth, smooth, uniform in thickness and without air holes; It is strictly forbidden to install scaffolding or hang heavy objects on the door and window frames, fans and mullions, and it is forbidden to step on the window frame, Casement or window mullions; If the surface of doors and windows is stained with oil stains, it should be washed with water-soluble pigmentum, and do not scrub with rough or corrosive chemical liquid.
