Plastic Wood Exterior Wall Panel Material Insulation Function
It is understood that the energy loss of housing residential is approximately 50% of the outdoor wall panel, accounting for 10% of the roof, about 25% of the doors and windows, the basement and the ground account for 15%, which can be seen that the wall insulation material is the main way to achieve indoor heat preservation. The plastic wood exterior wall panel is is a composite board formed by the extrusion method, injection moulding method and pressing method, which is made of thermoplastic plastics such as polyethene, polypropylene, polyvinyl chloride and their copolymer and wood powder, plant straw powder, plant shell and other wood powder material. A new outdoor wall panel decorative material having integrated decoration, insulation, soundproof, fire prevention, etc., its heat preservation effect is 7 degrees higher than the ordinary sheet, 10 degrees higher than the paint, can reduce the loss of indoor temperature, thus winter Create a warm home environment.
Plastic wood wall paneling sheets are currently mainstream insulation materials, mostly used in architectural decoration such as walls, doors and windows, and exterior WPC wall panel, which can be seen in the insulation of insulation. By applying environmental insulation materials in the product, the plastic wood wall paneling sheets has the effect of heat insulation in the summer, in the summer, suitable for the southern and north, to achieve the winter warm summer cool requirements we want. And the sound insulation effect reaches 29 decibels.
In the outer layer of the plastic wooden board, the inner cavity of the plastic wood wall paneling sheets is enclosed, and the middle is added to the self-insulated plastic wood board. This plastic wooden board can be applied to the outdoor wall panel of the steel structure, and the steel structure itself is realized. At the same time, it also reduces the weight of the building itself, saving materials. Now there are many outer WPC wall panel systems in the steel structure, and the plastic wooden board self-insulation is applied to steel structure, which does not only have the role of the outer wood wall paneling sheets, and it is no longer necessary to do an insulation layer alone. However, because the plastic wood self-insulation board is a new outdoor wall panel plate, the steel frame plastic wood exterior wall self-insulation system is a new exterior wall system, and there is no practical research and application before, and many jobs need to be carried out. Such as optimizing the formulation of plastic wood materials and the production process to reduce production costs and improve their durability; optimize the structural type of the sheet, improve its insulation.
The following focuses on some of the problems that need to be solved in the construction of steel structural plastic wood exterior WPC wall panel self-insulation system.
(1) Consider all aspects of the outdoor wall panel strength, construction speed, and convenient construction, it is determined to determine the section form of the plastic wood self-insulated sheet.
(2) After determining the section of the plastic wooden board, it should be determined to determine the connection between the plate and the board. According to the requirements of the building facade, the plastic wooden panels can be arranged in transverse and vertical two ways, but their vertical node and the manifold node are still designed.
(3) Determine the node structure of the steel structure plastic wood exterior WPC wall panel self-heating system. Plastic wooden board wall, the nodes, such as the node structure of the plate and the column, the node structure of the plate and the beam, the plate and the roof panel connection structure, the slate and the concatenation structure of the frame beam-column, and the upper and lower sides of the door and window are constructed. The daughter wall and the girder and the frame beam-column will be designed. However, the connection between the plastic wood exterior WPC wall panel plate and the connection between the plastic wood exterior wall panel and the steel frame structure has no detailed specification and atlas can be used for reference, so they can only refer to the outdoor wall panel of steel structures at home and abroad. The node structure and the relevant information of the connection method are configured to determine the node structure of the plastic wood exterior wall, and at the same time consider the material properties of the plastic wooden panel itself, determine the node construction and connection of the plastic board and steel structure.
(4) Determine the construction method of a self-insulated system in steel structure plastic wood exterior wall panel. In the construction of the steel structure, the construction of the wall panel is important. For example, the wall of the outdoor wall panel, the lifting and installation of the plastic wooden board, the installation, quality testing of doors and windows, etc. The construction method of steel structural plastic wood self-insulation WPC wall panel system has no specific operating norms in my country, can only refer to relevant specifications and construction methods, research on the construction method of steel frame plastic wood exterior wall self-insulation system, Specific construction methods for use in the construction of the actual engineering to guide the site is very meaningful.
