How to dismantle the second-floor prefabricated house?

1. Starting from the roof, dismantle waterproof glue, remove bolts, dismantle roofing materials, and then take roofing tiles. Then loosen the external tie rod (steel wire cross brace) with a wrench and remove it.

2. Dismantle the wallboard, pull it out one by one from top to bottom, and remove the doors and windows at the same time. If the circuit board is stuck, it should also be removed.

3. Dismantle the steel frame, dismantle the structural parts such as herringbone beam, ring beam and door frame one by one, and then dismantle the platform, stairs and walkway on the second floor. Finally, put down the post.

Note: It must be to prevent structural instability from causing danger. It is best to arrange the unloaded materials neatly at the beginning, which is convenient for sorting and does not affect the subsequent disassembly process.
