Description

Modularization concatenation container formula house

Technical Field

The embodiment of the utility model provides a relate to container equipment technical field, concretely relates to modularization concatenation container formula house.

Background

This section introduces to the reader background that may be relevant to various aspects of embodiments of the present invention and is believed to provide the reader with useful background information to facilitate a better understanding of the various aspects of embodiments of the present invention. Accordingly, it should be understood that the description in this section is for purposes of illustration and is not an admission of prior art.

In the aspects of engineering construction, oil exploration, army field operations, disaster relief and the like, during operation and training, the problem of camping is usually solved by a method of building a temporary shed or a tent, the building of the shed is a feasible method, but can only be used once, the labor cost, the time and the cost are consumed, the tent is built, the wind resistance, the rain resistance, the cold resistance and the sunstroke resistance are poor, and the service life is short.

The container house is made or a plurality of containers are spliced through a container, different living function modules can be made, but the requirements of double-spliced and multi-spliced container houses are more and more, but the splicing of the container houses is always a technical difficulty.
