Expandable Container House Installation Steps

Preparation of tools and personnel

Due to the large weight of the product, it needs crane, 4-5 personnel to assist the installation, and tools such as electric drill and cross drill bit.

Choose a suitable installation site

Confirm the geological conditions of the installation site (e.g. bearing capacity, drainage), and choose a compacted and level ground to place or install the products.

Placement of container house

Lift the product accurately to the determined installation location with a crane, and use a level to calibrate to ensure that the box is perfectly level.

Unfolding the container house

As the container house is folded during transportation, we need to unfold the container house.

Find the fixed panel on the side, loosen the screws on the fixed panel, and then unfold it outward. Generally the right side is unfolded first, and then the left side is unfolded, the unfolding steps can refer to the video below:

Screw fixing

The screw holes reserved on the roof, internal and external walls are fixed with self-tapping screws to ensure all connections are secure.

Sealing

Paste waterproof adhesive tape at the joints between the main box and the expansion board, and apply structural adhesive at the joints between the side base and the side wall to ensure sealing and waterproofing.

Electrical system connection

  • The main cable (cross-sectional area ≥6mm²) is connected to the distribution box through waterproof connector, and an earth leakage protector (action current ≤30mA) must be installed.
  • The box prefabrication has pre-buried PVC wiring pipe (lighting, socket circuit separation), the site needs to expand the area lamps and lanterns (such as LED flat panel light) and the main box distribution box connection, zero line and ground line need to be differentiated by color (zero line blue, ground line yellow-green dual-color).

Water supply and drainage installation

  • Water supply pipe: PPR pipe (hot melt connection), cold water and hot water pipe spacing ≥ 15cm, expanding the bathroom faucet and the main box water tank connection.
  • Drainage system: floor drains and toilet sewage pipes in the expansion area are connected to the main box sewage pipe (110mm in diameter), and the slope is controlled at 2%-3%.

Functional debugging and safety inspection

  • Structural safety check: check all bolts, welding points and the stability of the expansion mechanism.
  • Functionality test: check the water and electricity system for water and electricity leakage.

  2. Space and site requirements: different sizes of single expandable container house covers an area of 18 square meters -76 square meters, if you need more than one for the combination, the area required will be larger.
  3. Policy support: Although most of the over support, but it is best to determine whether your country supports the construction of containerized housing.
