In the design of systematic energy-saving doors and windows, the design of heat insulation aluminum profiles is the core part of the entire design. The quality of profile section design determines the performance and quality of doors and windows. The principle of heat insulation is to mechanically roll the non-metallic heat insulation strip (nylon 66) and two sections of aluminum alloy profiles into an insulated profile. In the profile design process, the main considerations are the effects of wind loads, comprehensive strength, stiffness and stability requirements. The optimal design is carried out. Under the conditions of economical cross-sectional area, the moment of inertia I and the cross-section resistance moment W are as much as possible. Increase. In the cavity after insulative heat insulation strip, urethane resin with “insulation king†is irrigated, and the energy convection effect of heat convection is more significant.
2, the gap weatherproof design In order to obtain better watertight, the use of equal pressure principle design isostatic glue, and drainage channels on the window frame material to divert rainwater, in order to obtain better air tightness, with sealant Bars to prevent air infiltration.
3. Hardware accessories Hardware accessories occupy a very important position in the systematic design of energy-saving doors and windows. The quality of hardware accessories affects the performance of doors and windows. The repetitive opening of doors and windows is achieved by hardware accessories. Therefore, it is also crucial to select high-quality hardware accessories. The quality performance of hardware accessories directly relates to the processing quality of doors and windows.
When designing systematic energy-saving doors and windows, we completely adopt the European standard notch, combined with special hardware, connecting and cutting, and the hardware runs smoothly and freely in the profile channel and is flexible to open and close. Can use imported hardware accessories, can use domestic accessories, can meet different levels of demand 4, hollow glass system of energy-saving doors and windows of the sound insulation performance is achieved by the hollow glass, while the energy saving of doors and windows is also insulated glass to block heat radioactive.
5. The design of rubber strips The material of the strips is EPDM rubber. Its advantages are: good weather resistance, good heat resistance, and good sealing performance. The main design considerations are: safe, convenient and reliable, watertight and airtight and reliable. As shown in the figure below, isotonic strips are used to retain water and airtight on the front; hollow strips are used for the second airtight; tower strips are used to press the glass.
Prefabricated K house are structurally sound and will last a long time!
Prefabricated K house are a kind of Prefabricated House. It uses light steel as the skeleton and sandwich panels as wall panels. It only needs to determine the design and basic area requirements, so the rapid construction of such container houses is also the same. All guaranteed. Moreover, standard accessories are used for later assembly, which can make reasonable use of space, and each part is intended to be connected by bolts, which is also very good in terms of practicability. Moreover, its material quality is high, its long-term reliability is guaranteed, and its stability is also very good.
Material safety is guaranteed
The prefabricated K-shaped house is a new type of light steel composite board house. It uses color steel, light steel and other materials for construction, and it is also very convenient to install. Moreover, its steel plates have a certain thickness, even if it is an earthquake of magnitude 7 or above, it can also ensure stability, and there is no need to worry that it cannot be used in some harsh environments. Therefore, even in some earthquake disaster areas, etc., such houses can also be used, and the safety is still very guaranteed.
Overall construction cost is lower
Compared with ordinary houses, the construction cost of prefabricated K-type houses is still very favorable. Because sandwich panels are generally used, the materials can be recycled, and the repeated disassembly and installation of the house, and the second use are also guaranteed. This can effectively reduce construction waste, and achieve the effect of energy saving and environmental protection. Moreover, this type of house has a long service life and can be reused many times, so its cost performance is also good.
High construction efficiency
Prefabricated K house and Prefabricated T House only needs to have a good basic design, so the construction can be completed quickly. The construction team only needs to complete the construction according to the drawings, and the house construction can be carried out quickly. Moreover, the interior decoration is simple, and generally some light decoration materials can be selected, which can not only save the overall decoration and construction costs, but also ensure that the house can be put into use quickly, and the reliability of use is also guaranteed.
