Description

Technical Field

[0001] The present invention belongs to the technical field of integrated house installation, and in particular relates to a large-space, large-span expandable box-type integrated house and a construction method thereof. Background Art

[0002] With the rise of the application of packaged container integrated houses in the project departments of engineering camp projects, the demand for buildings with large depth and high clearance is becoming more and more urgent. The internal clear height of traditional packaged containers is about 2.5 meters, which cannot be achieved. The existing technical solutions include processing special-shaped heightened columns, wall panels and door and window systems to meet the demand, so that the internal clear height is increased to 5 meters.

[0003] Existing technical solutions for raising columns have the following drawbacks: 1. Columns measuring approximately 6 meters tall require large bending machines for processing, which places high demands on the equipment and increases costs significantly due to the special-shaped components. 2. Using raised columns reduces connectivity and compatibility with other standard modules, resulting in poor overall coordination. Therefore, a solution is needed to achieve a larger span and higher clearance by adding crossbeam assemblies and through-the-top columns in the middle layer without using extended columns, while also ensuring proper connection and facade coordination between the raised space modules and other standard box modules.
