Sunshine room can be divided into four development stages according to its materials and manufacturing methods: one is the sun room with pure wood structure, the other is the sun room with pure steel structure, the third is the sun room with aluminum curtain wall structure, and the fourth is the steel and aluminum structure. Sun room.

1 After Columbus discovered the New World, before the Industrial Revolution, many tropical plants, flowers and fruits entered Europe. The cold climate of Europe could not adapt to its production. The European aristocrats liked to enjoy this kind of things, so the royal craftsmen built some The greenhouse meets the needs of the nobility. Later, it was discovered that these greenhouses are not only able to grow tropical crops as greenhouses because they are full of sunlight and green, and can form a special space for leisure, entertainment, family gatherings and studios. You can find these early sunrooms in some movies depicting the aristocratic life of the 16th to 18th centuries.

2 After the first industrial revolution, the 18th Century London World Expo, the United Kingdom built an exhibition hall covering an area of ​​80,000 square meters to showcase its industrial development. Its protagonist is a glass structure of pure steel structure, which is the peak of the early steel structure sun room. At this stage, the mass production of steel has further expanded the coverage of the early sun room. We can find a steel-structured sun room in the American feature film "The Sound of Music" and "Time Machine".

3 In the first half of the 19th century, due to the construction of skyscrapers, a new building material aluminum was widely used in building windows and doors due to its convenient forming, light weight and high strength. At the same time, the modern lighting roof and lighting ceiling are also made of aluminum structure. And with the improvement of living standards, the sun room has become an indispensable living space for middle and high income families in developed countries. Sunshine rooms in foreign countries have become a way of life. With the increase in the income level of the Chinese people and the massive construction of villas and duplex houses, the development of the Sunshine Room has become unstoppable. At that stage, people built their own sun room as they wished, liked the wood structure close to nature, and liked the industrial steel structure. The aluminum structure has become the mainstream of the sun room at this stage because of the standardization of a large number of curtain wall materials.

4 The steel room and aluminum structure of the sun room is mainly because some sun rooms are too large. Because of the high strength of the steel and the convenient welding, steel frames and aluminum electrodes are used. Build a large sun room. In China (especially in Shanghai), because the sun room is a new thing and the price is high, in order to reduce the cost, steel-aluminum composite (the aluminum-clad steel sun room) is adopted, and the steel as the structural body satisfies the strength problem. And aluminum as a surface decoration makes the sun room durable and more beautiful. It can be said that the aluminum-clad steel sun room was the product of China's national conditions at the beginning of this century. The advantages are higher strength and lower cost. The disadvantage is that the construction period is long and there is no standardization. During the construction process, there are many uncontrollable factors and large fluctuations in quality.

5 At present, the sun room at home and abroad has entered a new stage, namely, the factory-produced standardized room system (sum Rooms Stytem). In the United Kingdom, where the sun room originated, the annual sales of this type of sun room is as high as 400,000. Imagine that in such a projectile island country, there are so many sales, it is obvious that the sun room is a clear sun in China. Industry, Sunshine room products are really talking about the standard sun room system. According to the author, it has not yet been formed. The real sun room system should have the following conditions to be standardized. One/all profiles, components and accessories are all standardized production, ie factory production. That is, all the cutting, milling, drilling, tapping and other processing has been completed in the factory. The construction time of the sun room at the site was greatly shortened, from 2 weeks to 2 months of the original aluminum-clad steel or steel structure construction time, to 1-5 days. Second, due to the continuous emergence of new materials, aluminum and its alloys have various forms of performance, among which the most suitable material for the sun room is titanium-magnesium alloy, number 6063, which is 30 times stronger than ordinary doors and windows. %-40%, the price is 1.5 times that of ordinary aluminum. Use this aluminum alloy to make the strength and stability of the sun room. Anti-wind load and earthquake resistance have a good performance. Third, because the sun room needs to be exposed under the scorching sun, all plastic parts must have anti-ultraviolet function, that is, adding modifiers and anti-UV agents to the raw materials, so that the plastic parts are not yellowed and brittle and aging. Fourth / changed the way of packaging and transportation, just like the way IKEA changed traditional furniture. The sun room system makes the sun room so easy to disassemble, and greatly reduces the trouble and cost in the transportation process, so that when people move, as if to take away a piece of furniture, it is convenient to take away a medium-sized sun room.

Because the sun room system has the above conditions, it is called the system. It has a high degree of standardization. On-site construction time is short, high intensity, safe and reliable. And with a dozen basic shapes according to its division, it can be combined to play a variety of combinations. Can also meet the creative needs, any combination of different innovation from the sun room.

6 aluminum-wood composite sun room, aluminum-wood composite sun room is made of solid wood as the main body, and the outer side is supplemented with high-strength aluminum alloy profiles. The role of aluminum alloy profiles is not only to protect the wood, but more importantly, through the optimized combination of the two materials. The strength of the window structure is increased to the mathematical quantitative index that the strength of the solid wood structure cannot be achieved. It has a higher demand for wood. All wood must be degreased, anti-corrosive and flame retardant, and it is a special laminated material to ensure the stability of wood, avoid cracking, decay and other phenomena of wood, and the wood structure is more reliable. At present, the sunlight house of this type of structure mainly relies on imports.

In summary, it is not difficult to see that the aluminum-wood composite sun room, that is, the sun room system, will become the mainstream product of the development of the sun room in the future. With the improvement of people's living standards, the living conditions will improve. There will be more and more sun rooms, and more and more standardized use in duplex terraces, joints, single-family villas and numerous window rooms.

The sun room has a nice English name - winter garden, literal translation is the meaning of the winter garden. It has two meanings: First, it achieves intimate contact between the living room and the sun, and enjoys the warmth of the sun even on cold winter days. Second, due to the unique insulation effect of the sun room, the function of the greenhouse can be realized, and even in the cold winter, it can create a warm living environment for the family. The sun room can be built on the terrace of the duplex building, the private garden on the first floor, the top floor of the building, private villas and other places. The aluminum-wood composite sun room has an independent façade and top structure, which can be well integrated with any architectural style building. It has good sound insulation effect and overcomes the defects of traditional sun room cold winter heat, fog and ice. .
