Key precautions when knocking down buildings indoors and outdoors in Inner Mongolia include:
1. Local beams with joists on the walls cannot be removed; since the joists support the upper floorboards, if removed, the floorboards above would collapse downwards, posing a considerable danger.
All load-bearing walls must not be removed.
Before knocking down walls, try to confirm with the property management first before proceeding with the demolition; avoid unnecessary troubles during the building demolition process.
4. The wall is hammered from the side where it was cut, not from both sides, otherwise cracks in the wall may form.
Step-by-step, the wall-breaking process is from the bottom up, rather than from the top down.
6. Post-demolition, wall restoration efforts cannot be cost-saving. For instance, when constructing a new wall with red bricks, a steel bar should be added to the wall of the new building. The steel bar is a local construction technique for joining old and new walls, which involves stretching the steel bar to ensure the stability and seismic resistance of the wall.
On the door opening in the wall, adding a horizontal beam above the opening can distribute the pressure on the upper wall, preventing the direct pressure from the upper wall from resting on the door frame.
Prior to the wall demolition, maintenance of the existing products is required, such as wrapping doors and sealing pipes. Ensure thorough maintenance before the wall is taken down to prevent pipe blockages or damage to original items.
After the house is demolished, all the debris should be cleaned up thoroughly before proceeding with the wall demolition.
