Bearing wall
In the renovation, the load-bearing wall cannot be changed and many people know it. But what kind of wall is a load-bearing wall, not many people can make it clear. Generally, in a brick-concrete structure, all prefabricated walls cannot be dismantled or doors can be opened; brick walls larger than 24 cm are also load-bearing walls and cannot be removed or modified. The walls that are knocked on by the “quiet voice†are mostly non-bearing walls and can be demolished.
In addition, some people open the window on the load-bearing wall, which also undermines the weight of the wall. It is also not allowed.
If you want to demolish the wall in the house during the renovation, it is best for construction professionals to look at it to determine if it is a load-bearing wall before construction. Prior to construction, the property management department should also report to the record and be approved for construction.
Reinforcement in the wall
If the housing structure is better than the body of an adult, the reinforcement in the wall is the bones of the person. If the steel is damaged when the pipeline is laid, it will affect the bearing capacity of the wall and the floor. In the event of an earthquake, such walls and floors can easily collapse or break.
Beams in the room
These pillars are used to support the upper floor slabs. After the upper floors are removed, they will fall, so they cannot move.
Low wall on the balcony
There is a window on the wall between the general room and the balcony. These doors and windows can be changed, but the walls below the windows cannot be moved. This wall is called "weight wall" and it acts like a scale to provoke a balcony. Demolition of this wall will reduce the bearing capacity of the balcony and cause the balcony to fall.
"Three defenses" or "five defenses" door
The door frames of these doors are embedded in concrete. If the doors are demolished, they will damage the building structure and reduce the safety factor. It also destroyed the building structure at the entrance and it was even more difficult to reinstall the new door.
Waterproof layer for bathroom and kitchen
There is a waterproof layer under the ground in these places. If it is destroyed, the downstairs will become a water curtain hole. Therefore, be careful not to damage the waterproof layer when you replace the floor material. If it is damaged and reconstructed, you must do a “24-hour water seepage test†that is, watering in the kitchen or bathroom, if it does not seep after 24 hours.

All aluminum alloy material has strong plasticity and never rusts. Fluorocarbon baking powder is delicate, smooth, and long-lasting without fading. The product is intelligently matched with various smart devices, making it a minimalist, luxurious, and youthful fashion design style.
Advantages of aluminum doors:
Strong and durable: Aluminum alloy has high strength and hardness, can withstand the collision and wear in daily use, and has a long service life.
Corrosion resistance: Aluminum will naturally form an oxide film in the air. This oxide film can effectively prevent aluminum from further oxidation and corrosion, making it stable and not easily damaged in environments such as moisture, acid and alkali.
Good fire resistance: Aluminum alloy has good high temperature resistance, which can play a role in fire prevention to a certain extent and increase the safety of living.
Good sealing: Aluminum doors can be equipped with high-quality sealing strips to effectively improve the sealing performance of the door, and have significant sound insulation, heat insulation, and dustproof effects.
Various styles: Through different surface treatment processes and designs, a variety of colors and styles can be achieved to meet different decoration styles and personal preferences.
Environmental protection: Aluminum is a recyclable material and conforms to the concept of environmental protection.
