Nested module, nested modular structure and longitudinal installation method thereof

The invention relates to a nested module, a nested building structure and a nested building modular longitudinal installation method thereof. The nested module comprises an inner module and an outer module which can relatively slide; the nested building structure comprises a high-rise framework and the nested modules arranged on the high-rise framework; during the nested building modular installation, two groups of nested building modules are respectively conveyed to two vertically adjacent layers of frameworks; then, the inner module of the nested building module at the lower layer upwards slides out of the outer module; the inner module in the nested building module at the upper layer downwards slides out of the outer module; and finally, the two inner modules contact to form a stable structure. The nested module, the nested building structure and the nested building modular longitudinal installation method have the beneficial effects that when the nested building structure and the longitudinal installation method are used, the manufacturing quality can be improved; the construction period is shortened; and the cost is reduced.
