In the development of PC sunshine house, the main structure of PC sunshine house is the vitality of PC sunshine house and bears greater strength support. Therefore, the main structure material cannot be ignored. In order to reduce costs, domestic users adopt steel-aluminum composite (aluminum-clad steel PC sunshine board house) materials. Steel as the main structure meets the strength problem, and aluminum as the surface decoration makes the PC sunshine board house more durable and more beautiful. Its advantages are high strength and low cost, but its disadvantages are also obvious. The construction period is long and cannot be standardized. During the construction process, there are many uncontrollable factors and the quality is uneven.
Judging from the main materials of the PC sunshine board house at this year's construction expo, the wood structure PC sunshine board house accounts for a certain proportion. The relatively new material is also titanium-magnesium-aluminum alloy, which is 30% stronger than ordinary doors and windows. 40%, and the price is 1.5 times that of ordinary aluminum. Using this aluminum alloy, the strength, stability, wind load resistance and seismic performance of the PC sunshine board room have good performance.
However, Baikeluo’s engineers believe that common building materials such as titanium-magnesium alloys, steel, wood, etc. have shortcomings, such as not easy to form, excessive weight, poor heat insulation, and easy to deform and rot. Skeleton structure can only be used in components. Becklow believes that the use of thermally insulated and broken bridge products with steel structures is a new trend in the development of PC sunshine board houses.
Glass hollow laminated PC sunshine board room, with aluminum clad steel frame and hollow glass, "I didn't expect it to be too hot, and the heat dissipation is very slow, there is a hot air when I walk in after dusk."
Now, he is rebuilding the PC sunshine board room. Someone introduced the use of insulating glass, saying that the heat insulation effect is good. Some companies also suggest using hollow laminated glass to enhance the safety performance of the PC sunlight board room, but they are afraid of affecting the sunlight and obstructing the view. According to the reporter's knowledge from a number of PC sunshine board house companies, the previous PC sunshine board houses basically adopted a toughened glass roof, which has good permeability but poor heat insulation and heat preservation performance. Afterwards, the insulating effect of the hollow glass roof is improved, but the safety performance is still poor. The current broken bridge aluminum PC sunshine board house basically uses hollow laminated glass, which has good permeability and good heat preservation, but the cost is relatively high. The reporter checked the information. A newer technology dimmable PC solar panel room product appeared in the US market. When the power is off, the glass is opaque, and the glass is transparent when the power is turned on, which can protect indoor privacy and control indoor sunlight intensity. .
Because the PC sunshine board room needs to be exposed to the hot sun, all plastic parts must have anti-ultraviolet function, that is, add modifiers and anti-UV agents to the raw materials to prevent the plastic parts from yellowing, brittle and aging.
The shape of the PC sun board house can be designed by yourself. The key to the change lies in the roof. At present, the roof of the PC sun board house has single slope, opposite slope, diamond roof, gem roof and other categories. However, the shape of the PC sunshine board room should be designed according to the environment. For example, the terrace PC sunshine board room generally has one facing wall, two facing walls or three facing walls, and the design is naturally different. The garden PC sunshine board house is mostly a kind of wallless PC sunshine board house, mainly Chinese and European style.
Even the European-style PC sunshine board house in the villa, the overall shape is Mediterranean, Byzantine, Victorian, and Gothic. Among them, the Victorian style under the upper spire and the Gothic style of the minaret arch are suitable for villa buildings and roof terraces with larger garden areas. The PC sunshine board room is surrounded on three sides, and one side can be connected to the living room or room. The Byzantine style with curved roof is suitable for villa gardens or terraces, large terraces of multi-storey and small high-rise apartment houses. The upright support frame and the Mediterranean style with inclined flat roof are suitable for the unroofed balcony of multi-storey or small high-rise apartment and the corner of the bottom of the villa.
Quality measurement standard
There are many brands of PC sunshine board house in Guangzhou, and the reporter counted no less than 20 in several major home building materials markets. For example, Geting, Wen Zhixin, Velux, Huajie, Conao, Becquer, Sovereign, etc., which are more reliable in quality, can be through the appearance design, overall structure design, thermal insulation performance, door and window combination airtight performance. To measure in all aspects.
The appearance design of the PC sunshine board house is very important. The appearance design of the PC sunshine board house provided by most companies is partially modified from the existing classic appearance. Therefore, companies with more original appearance design schemes have relatively stronger strengths.
The overall design of the PC sunshine board house mainly includes door and window matching design, thermal insulation structure design, drainage design, stress structure design, etc. Especially in the overall drainage design, a "flooded room" may appear with a slight leak.
Thermal insulation performance is the key criterion for judging whether the PC sunshine board house is energy-saving. Better thermal insulation effect requires the use of thermal insulation profiles and LOW-E insulating glass, and the use of EPDM rubber materials for sealing.
PC sunshine board houses are generally built with multiple components. At the same time, in order to meet the ventilation requirements, most of the facade and top of the PC sunshine board houses are combined with openable doors and windows. The quality of the doors and windows has become the success of the sealing performance of the PC sunshine board houses. The key to no also affects multiple effects such as waterproofing and sound insulation. While emphasizing the airtight performance, it must also be able to effectively solve the problem of air circulation, so that the indoor air has a better circulation effect.
