Container House Prefabrication

Container house prefabrication involves breaking down the building into independent unit modules, completing production in a factory, and then transporting them to the site for assembly. Using containers as the basic structural modules, they are transformed into habitable or office buildings through modifications. The specific prefabrication process is as follows:

Bottom Frame Installation: First, connect the lower corner fittings and bottom beams with bolts, place the marking strips and connect them to the bottom beams with bolts, and measure the diagonals to ensure the bottom frame is perpendicular to each other. Then, connect the bottom cross members, paying attention to distinguishing between the three specifications. Next, connect the columns to the bottom frame, leaving the bolts slightly loose to allow for movement. After that, lay the MGO boards, leaving gaps for the wall panels. Use instruments to measure whether the floor is level, and if not, use shims to level it.

Top Frame Installation: Connect the upper corner fittings to the top longitudinal beams and tighten the bolts. Then, connect the upper corner fittings to the columns, also leaving the bolts slightly loose. Next, connect the top transverse beams to the upper corner fittings. Use a level to measure whether the columns are perpendicular to the ground, and temporarily support and adjust them with top marking strips. After removing the supports at the connections between the upper and lower corner fittings and the columns, first install the central longitudinal member and its two side long wiping strips, and finally reinforce the connections at the junctions of the top members.

Drainage System Installation: Connect the corner fittings to the drainage channels along the edges, embed the drainage channels into the top, and fix the drainage pipes to the top beams. Secure them with self-drilling screws at least every 25 cm, apply sealant at the connections, and finally install the downspouts.

Wall Panel and Interior Installation: After attaching sealing strips to the inner sides of the columns, bottom beams, and top beams, install the wall panels in sequence, securing them at the bottom and top. A standard container house unit has one door and two windows, whose positions and sizes are flexible but cannot be installed adjacent to the columns; they must be supported by wall panels on both sides. When installing the ceiling, use different fixing methods depending on whether there are wall panels on both sides. Drill holes on the inner side of the wall panels to fix the wires to the steel wires and pass them through the wall panels. Cut the glass wool to the appropriate size and lay it on the roof. After applying sealant to the inner edge of the drainage channels, lay the roof tiles and fix them to the inner side of the drainage channels.

Some prefabricated container houses have completed all processes such as water and electricity installation and interior decoration in the factory and can be directly assembled on-site upon arrival at the destination.
