What's the difference between high-rise buildings and multi-storey buildings for builders?

Hehe, for the construction party, the top management should pay attention to setting out, because it is easier to repeat the work.

For builders, the differences between high-rise and multi-storey buildings are as follows:

1 has different shapes. Generally, the high-rise building is square or quasi-square, while the multi-storey building is mostly rectangular.

2, pay-off, high-rise pay-off more than one instrument: plumb instrument, used to measure infrared rays upwards.

3. The structural forms are different. The multi-storey structure is generally frame structure, and the high-rise structure is frame-tube structure. So the specific labels may be different. The column concrete label of high-rise column and beam slab with 20 stories (or above) is higher than that of beam slab, so attention should be paid to the pouring method during construction.

4. The erection methods of the outer frame are different, and there are many ways adopted by the top. For example, the anchor ring is buried in the plate in the form of channel steel, and multiple layers may be erected by the outer frame at one time.

5. Different modes of vertical transportation. Generally, there are hoists for high-rise vertical transportation, but not for multi-floors. High-rise tower cranes must be attached because they exceed the standard height of tower cranes, and multi-storey towers are generally not needed.

6. Because of the different foundation forms, high-rise buildings may have raft foundation or composite foundation forms such as manual digging piles, and the multi-layer foundation forms are relatively simple (except for sudden changes in soil layers).

7. The stairs are different. High-rise buildings are generally scissors stairs (taking residential buildings as an example), which connect two floors by running stairs, and there is no turntable (rest platform) in the middle. The multi-storey is two floors with a rest platform in the middle.

8, different water supply systems, high-rise water supply to partition, secondary water supply; And the multilayer is not divided.

The above is only in general.

Personal opinion, for reference only.
