Broken bridge aluminum doors and windows as a substitute for traditional doors and windows, once listed, it has attracted much attention for its superior performance and beautiful shape. As we all know,
broken bridge aluminum doors and windows it has many properties such as air tightness, water tightness, sound insulation, environmental protection, energy saving, etc. The realization of these properties not only follows
broken bridge aluminum doors and windows the profile itself is related to the design, and the unification is also closely related to the installation technology and technological level. Today, let's follow the editor and learn about it.
Broken bridge aluminum doors and windows the installation process.
(1) device procedure:
window frame in place & rarr; Frame fixing & rarr; Fill plug gap & rarr; Device debugging hardware accessories & rarr; Safety glass & rarr; Glue finishing.
(2) construction key:
the window frame device of each floor should be pulled through horizontally and vertically, and it is better to pull down the diagonal line obliquely. The first thing is to open the window to achieve horizontal common, straight up and down, accurate.
When the window frame and the wall are fixed, first fix the upper frame, then fix the frame, and use plastic expansion bolts to fix it.
The inner cavity of the expansion joint between the frame and the opening is made of closed-cell foam, foaming agent and other elastic materials fill plug, and the outer surface is sealed with sealant.
As the saying goes
broken bridge aluminum doors and windows three-point product seven-point device, as long as the device skills are good, you can make your doors and windows more durable.
1, before the device, check the shape and orientation accuracy of the door and window openings to check whether the quantity and orientation of embedded concrete fit the planning requirements. Whether the high-rise windows are connected to the lightning protection belt according to the rules should urge the construction of the unqualified part. Unit rectification.
2. The oxidation material doors and windows embedded with cement mortar should be treated with anti-corrosion before being put on the wall. Except for the outer window frame of the exterior wall, the external appearance is maintained by sticky tape or plastic tape. There shall be no sticky tape or plastic tape on the wall to avoid water seepage in the gap of the joint.
3. After the doors and windows are put on the wall, use wooden wedge pieces to adjust the positioning and then use fastener to fix them. Do not use iron nails or wooden wedge to fix them. Before caulking, the supervision unit or the construction unit should make inspection records of shade engineering and check the straight, horizontal and diagonal lines of doors and windows. After caulking, the wooden wedge should not be left in the caulking.
4,
broken bridge aluminum doors and windows waterproof adhesive between window frame and wall must be done after the wall is boring. If the wall is not boring and the dust is not removed, the water vapor released by the clean wall will fail the seal.
5. After the wet operation is completed, the device glass and Casement or sticky tape of the maintenance before plastic tape and the dirt on the window frame part will be eliminated.
6. After the glass and Casement device, check whether the accessories are missing, whether the device is firm, and whether the casement open and close the window should be closed before opening and closing sensitive inspection to avoid Casement damage caused by heavy rain.
7. Response before inspection
broken bridge aluminum doors and windows cleaning and self-inspection shall not be carried out. Cleaning agents corrosive to aluminum profiles, glass and hardware accessories shall be used to rectify the problems caused by self-inspection in time.
If you want to make qualified
broken bridge aluminum doors and windows, not only good materials, but also strict standard operations step by step in accordance with the process
1 Insulation aluminum insulation principle
heat insulation aluminum profile is a combination of aluminum alloy profile and thermoplastic mixed material heat insulation strip. Rolling heat insulation aluminum alloy profile is a high-density polyamide PA66 adhesive strip with good heat insulation performance, or polyvinyl chloride hard plastic adhesive strip is roll finishing through threading, which makes aluminum and plastic together. Foamed heat insulation aluminum profile uses heat insulation strips to insert the inner and outer aluminum profiles into one, and fills polyurethane foam in the formed heat insulation cavity to become a "cold bridge" of heat insulation aluminum alloy profiles, reaching insulation, the effectiveness of energy conservation.
2 Production process
the first process is to check the surface quality and scale standards of profiles. The inner and outer aluminum profiles can be anodized or electrostatic powder sprayed profiles. It can also select different color ingredients for the inner and outer aluminum profiles, and connect through broken bridges to form the inner and outer two-color aluminum alloy doors and windows.
The second process is to stick the maintenance film, and the primary maintenance is to keep the surface quality of the profile from being damaged during the processing and transfer process.
The third process is that tooth opening is the key process, and the first is to form a serrated Teez by rolling the two inner walls of the insulated aluminum profile through the slideway. After rolling embedded PVC hard plastic adhesive strip, it is fixed together.
The fourth process is the threading and rolling process, which is an important process. The threading is to penetrate polyvinyl chloride hard plastic heat insulation strip into the heat insulation aluminum profile with open teeth within Teez through the threading equipment, and then through the rolling equipment, roll the insulated aluminum profile with PVC hard plastic adhesive strip
the fifth process is the process of filling polyurethane foam in the heat insulation cavity. For the foamed heat insulation aluminum profile, the profile is placed in a two-component metering and mixing distributor, and the mixing nozzle is poured into the heat insulation cavity for natural foaming.
The sixth process is that packaging is the final process. It can be wrapped with plastic film suit or wrapping paper. The first thing is to maintain that the profiles are not damaged during transportation and processing.
3 routine inspection of heat insulation profiles and verification of heat insulation effect
a/shear strength test: take (100±1)mm long composite insulated aluminum alloy profiles and store them in an environment of (23±2)℃ and humidity of 45% ~ 55% for two days, after the shear strength detector, the effect force is evenly ground to the profile section, and the feeding speed is 1~5mm/min, recording the load and the corresponding shear deformation number.
B/shear strength accounting formula: T = F1mix/L Formula: T -- shear strength; F1max -- maximum shearing resistance; L -- Sample length.
The combined elastic value is the ratio of effect force per unit length of shear failure to displacement H, which is calculated according to the following formula:
C/K = F1/(h×l) DIV> In the formula: K -- combined elasticity; H -- displacement under the effect of shear force F(N), Unit: mm; L -- Sample length; F1-shearing resistance.
D/transverse tensile strength test: transverse tensile strength test is carried out after shear force failure. The shear force fails after 2mm displacement between the inner and outer aluminum alloy profiles. After the transverse tensile strength detector, the effect is evenly applied to the inner and outer aluminum alloy profiles of the insulated aluminum profile, and it is stretched outward.
E/transverse tensile strength accounting formula: Q = F2max/L Formula: Q -- Transverse tensile strength; F2max -- maximum tensile strength; L -- Sample length.
