The size of the building red flag.

The red flag of the building is 288 cm long and 192 cm high. 2. It is 240 cm long and 160 cm high. 3. Length 192 cm and height 128 cm. 4. Length 144 cm and height 96 cm. 5. It is 96 cm long and 64 cm high. The size of the red flag is not uniform, the length-width ratio is 3: 2, and there are five standard sizes.

Introduction of buildings and houses

With the continuous development of science and technology, the construction industry is also advancing with the times. At present, reinforced concrete structures are widely used in Gai Lou, and the main stage usually lasts for four and a half days, mainly including erection of internal steel pipes, formwork support, steel bar binding and concrete pouring.

For the developed prefabricated buildings and steel structure key areas, the future prefabricated buildings account for the new building target, and key cities have made great efforts to develop. At present, the project adopts prefabricated buildings, which directly saves the formwork.

After the internal frame is built, the cast-in-place slab produced by the manufacturer is directly used as the template, and the concrete can be directly poured on the cast-in-place slab just by tying the top steel bar. The volume of concrete is less than half of the previous one, and it only takes about 3 days, which saves the construction period and promotes the transformation, upgrading and green development of the construction industry.

Although only floors and stairs are cast-in-place at present, I believe that beams, columns and walls will be prefabricated in the future, and it will be faster.
