What is the construction scheme of prefabricated houses?

Construction scheme of the mobile home erection facility

I. Construction process

Setting-out-foundation trench excavation-C15 concrete foundation ground beam and ground concrete cushion construction-ground beam installation-column installation-floor I-beam system installation-walkway system installation-external wall panel installation-window installation-door installation-canopy system installation. Waterproof grooves should be installed between the ground beam and the wall panel, and the waterproof grooves should be closed with glass glue to prevent water leakage. The verticality of column installation shall be measured by magnetic force drop, and the deviation shall be controlled within L/1 and ≤ 1 mm.. Gap between walkway boards is filled with glass glue. Joints between roof panels are sealed with sealant. Iii. construction requirements

1. grey line setting out: set out according to the location of the living area plan (attached).

1) The installation position of each component of steel structure should meet the design requirements, and the welding parts on site should be accurate without false welding or missing welding.

2) Fasteners A and B shall comply with the provisions of GB5782. Bolts must be installed correctly and padded according to the design requirements, and there shall be no shortage or omission. C, connecting bolts between components must be tightened.

3) paint a, after on-site welding and transportation, the peeling place of primer should be repainted with a layer of antirust paint b, and the exposed part of the component should be painted with a second layer of topcoat, and the paint can not be missed, peeled, hung and rusted.

4) wall a, the first piece of sandwich color steel plate and wall surface must be corrected according to the layout diagram. The corner and external corner of umbrella wall are sealed with angle aluminum, and the connection between plates is made of I-shaped aluminum. The walls must be vertical, the caulking depth is consistent, neat and clean, the wall surface should be clean, the color is consistent, the plate seams are neat, and rivets should be nailed with φ Φ5X13@3. B, indicate the position of doors and windows according to the design drawings, cut out the position of doors and windows with a cutting machine, install windows according to the position of doors and windows, the windows are plastic steel windows, the sandwich colored steel doors cut by the doorman, and finally carry out the bottom ceiling, which is made of PVC gusset plates.

5) doors and windows a, doors and windows are installed correctly and fastened with bolts. B, doors and windows position installation should be flexible and no block phenomenon, glass should not have pits and cracks, glass clean, accessories installed firmly.

6) Floor A and floor slab shall be paved with ash, and cracks between slabs are not allowed to be installed and used. The surface of cement or fine stone concrete shall be tightly calendered, and there shall be no defects such as cracks, peeling and sanding.

7) The color steel plate gutter joint should be firmly connected, and the joint should be waterproof glue. There should be no water in the gutter and no leakage. The downspout should be installed vertically and firmly, and the hoop spacing should be 13.

2. During storage and stacking, all components shall be transported with care, and bumping is strictly prohibited. Stacking pressure and corrosive items are not allowed at the same time.
