There are various forms of Chinese dwellings, from south to north, self-built houses suitable for local use have been developed according to local conditions. However, with the continuous convergence and evolution of architecture, the popularization of building materials and man-made equipment, and the wide application of mechanical techniques, the convergence of architecture is due to the gradual reduction of those factors that need to be adapted to local conditions and gas conditions.
Over the last 20 years or so, there have been a large number of flat-roofed houses in most areas. This is due to changes in construction methods, changes in construction materials, changes in living concepts, and the continuous evolution of man-made equipment. At this stage, most of the houses built by farmers were made of clay-fired bricks, and the floor slabs were made of prefabricated slabs. During this period, a large number of one- or two-story prefabricated slab flat-roofed houses appeared in southern China.
The appearance of the flat-roofed house is a new attempt to build the traditional small green tile slope roof in the past. This masonry structure continues to develop into a brick-concrete structure that is still widely used today, and a series of structural strengthening practices such as structural columns and ring beams appear on the basis of the original brick masonry.
However, there are some problems with flat roofs.
1. In general, the thermal insulation performance is not as good as that of sloping roofs
2. The probability of waterproof problems is also high;
3. And the roof form is relatively monotonous.
Flat-roofed houses also have advantages.
1. The cost is relatively cheap, which is an important reason for attracting many self-built houses
2. More and more modern and simple architectural styles have entered the field of vision of Chinese, and the sense of form of flat roofs has begun to be liked
3. For rural areas that need to dry grain and crops, the flat top is a good place;
In contrast, sloping roof houses also have corresponding advantages and disadvantages.
1. The cost is relatively high
2. The construction difficulty is also relatively large;
3. The construction period will be slightly longer;
4. The sloping roof is rich in form, the roof waterproofing and drainage are smoother, and the thermal insulation performance is also better.
In summary, the roof form is a very small part of the whole building process. With the continuous progress of the times, more and more architectural forms will be accepted, and more and more diverse building materials will be used. In this changing era, flat roofs will become more and more beautiful, and sloped roofs will always occupy their place in the roof of buildings as a form of architecture.
And all of this indicates that self-built houses are constantly progressing under the impetus of the times!
