WHAT IS THE EXPANDABLE CONTAINER HOUSE

The expandable container is a mobileroom container that can be depolyed manually on site by folding it out, changing one into three.

EXPANDABLE CONTAINER HOUSE STRUCTURE

27-72 square meters of extra-large space, 12 levels of wind resistance, nine levels of earthquake resistance, 20 feet that can be stacked up to twice the amount. others can only be stacked one time; can open and shutdown 120 times. very mobile, best choices are one bedroom with living room and a kitchen and a bathroom; two bedrooms with living room and a kitchen and a bathroom; three bedrooms with living room and a kitchen and a bathroom.

Step 1:Clarify Material Access Standards (Source Control)

Create a "review of qualification + rechecking sample" process. Give no more than a certain amount for key parts like Q355B steel (5700psi), EPS thermal heat saver (leakair 0.042W/(m-m).K)), and door lock (brings hold hold 13500N) to keep starting quality under control.

Step 2:Steel Cutting and Blanking

Adopt CNC plasma cutting. The deviation of size should be ≤ ±1mm, the right angle of the cut should be ≤ 0.5mm/m , and burrs or missed corners should not occur. Make a 100% appearance check for the cut edge.

Step 3:Frame Welding

Follow CO2 gas shielded arc welding (present: 120-180A, 20-25V). Keep the weld height: 6mm or higher; avoid cracks and deformations. Conduct ultrasonic flaw detection for all the welds of mainframe; rework the unqualified welds and make re-inspection.

Step 4:Frame Straightening and Forming

After that, the oblique shift should be less than or equal to 3mm,column vertical run out less than or equal to 2mm/m and the beam flatness less than or equal to 1mm/m. carry out 100 Volunteer visa examination and magnetic particle examination on key parts to make sure there is no crack and deformed.

Step 5:Enclosure System Installation (Core of Thermal Insulation and Waterproofing)

Use 1.8mm magnesium oxide boards for the floor with weld spacing ≤ 200mm and no hollowing. Make sure the splicing gap of EPS thermal insula-tion boards ≤ 2mm. The cut-off of outside wall color steel plates ≥ 100mm, the roof slop ≥ 5°, and do 24-hrs water tightness test to avoid leak.

Step 6:Supporting System Installation (Doors, Windows, Water and Electricity)

Ensureness of door and window prevents leaked air ( 0.5kPa air leakage ≤ 0.1m³/(h· ㎡)). Use toughened glass of own 5mm. Use BV wire and ,master pipes in water and electricity system. Use water pressure of 0.8 MPa for 30 min, as as pressure failure of 0.05 MPa., Pass rate for terminating powered on.

Step 7:Factory Acceptance and Filing (Inspection Closure)

Follow the three-inspection system (self-inspection, mutual inspection, special inspection). Place labels on qualified cabins and take photos for record-keeping. Remove unqualified products and repeat the work. Keep all records for more than 3 years.

Step 8:Delivery Acceptance Coordination

Customers will be with our QC people for acceptance, and they will sign the confirmation form if not objected. If there is a problem, the corrective plan shall be put within 24 hours and re-inspection shall be carried out after correction.

Step 9:Quality Tracking and Feedback

Create good files and follow the content of the plan of "one month regimen, three months check, and 1 year maintain" only. Face customer problems within 48 hours and solve within 72 hours. In case of emergency go to the place within 24 hours.
