It is very important to prevent earthquakes in home decoration. You can't just change four places.
In recent years, the problem of earthquake prevention and earthquake resistance in building decoration has attracted more and more attention from consumers. It is extremely dangerous to smash the load-bearing wall in the decoration. Especially in the case of an earthquake, its shortcomings are easily exposed. According to experts, under normal circumstances, if the load-bearing wall is demolished in a large area on the first floor, the seismic performance of the building will be weakened and the load stress will be abnormal. If an earthquake of magnitude 8 occurs at this time, the building is likely to collapse as a whole. In addition, it is not the load-bearing wall on the first floor that is the most important, but the importance of other floors is decreasing. Even if the first floor load-bearing wall is not removed, the load-bearing structure of the building will be deformed and the structure will become more fragile, and the possibility of devastating collapse is still very high.

In the face of life safety, luxury and beauty can take a back seat In order to resist earthquakes, what places can't be changed at will during decoration?

1 load-bearing wall

What kind of wall is a load-bearing wall? In general brick-concrete buildings, precast slab walls are load-bearing walls.

Never remove or open doors and windows. Brick walls over 24 cm are also load-bearing walls. Never touch the load-bearing wall when decorating, even if you dig a big hole in it. Arbitrary demolition and alteration will destroy the bearing capacity of the wall. If the building structure is compared to an adult's body, the steel bars in the wall are human bones and muscles. If the steel bar is destroyed when the pipe is buried, it will affect the bearing capacity of the wall and floor. If there is an earthquake, such walls and floors will easily collapse or break. In addition, the beams and columns in the room are used to support the upper floors. After being demolished, the upper floors will collapse and never move. How to distinguish non-bearing wall from bearing wall?

Judging from the sound: it's a light wall knocking on the wall, with a crisp big echo, while the load-bearing wall should not be too loud. In terms of thickness, the wall thickness of non-bearing wall in plan view is obviously thinner than that of bearing wall.

Load-bearing walls are relatively thick, second only to external walls, and the thickness is generally about 24 cm. Generally speaking, when the load-bearing wall is a brick wall, the structural thickness is 24cm, the structural thickness of the external wall in cold areas is 37cm, the structural thickness of the concrete wall is 20cm or 16cm, and the non-load-bearing wall is 12cm, 10cm, 8cm. Judging from the position: the external wall is usually a load-bearing wall; And the wall used by neighbors is also a load-bearing wall.

Bathroom and kitchen

Anyone who knows a little about earthquakes knows that small spaces, such as kitchens and bathrooms, are relatively safe when earthquakes occur, but the floors of these spaces cannot be changed at will, otherwise they will be transformed from "safe areas" to "dangerous areas". For the semi-brick wall of the bathroom, if the supporting beam supporting the wall is designed in the floor structure, it can be removed, otherwise it cannot be removed. In addition, there are waterproof layers on the floors of the kitchen and bathroom. If they are damaged, all the water will seep downstairs, and the downstairs will become "water curtain cave". Therefore, when replacing the ground material, we must be careful not to destroy the waterproof layer. In case of damage, remember to build it as soon as possible and do a "24-hour water seepage experiment", that is, fill the kitchen or bathroom with water. If there is no leakage after 24 hours, it is qualified.

Be cautious in rebuilding old brick-concrete houses

Unreasonable apartment type, small area, unreasonable function distribution, unreasonable lighting, etc. are all "common diseases" of old houses. Therefore, many people equate new clothes in old houses with a series of renovation projects such as knocking on the wall and knocking on the ground. In fact, most of the old houses are brick-concrete structures, and the walls first play the role of bearing and earthquake resistance, and then the role of enclosure and separation. If the load-bearing wall is destroyed only to realize the idealized spatial pattern, the load-bearing and seismic capacity of the wall will be weakened, resulting in potential safety hazards.

Design experts remind the owners of renovated old houses that they must consider the structure and safety of the house when re-nesting, and they can be bold and creative on this basis, otherwise once they "start", they will cause irreparable losses.

3 Low wall beside the balcony

In most houses, there is a door and a window on the wall between the room and the balcony. Many families choose to tear down the wall between the room and the balcony and transform it into an open balcony. Although it is beautiful, it is full of danger. The doors and windows at the junction of balcony rooms can be removed and replaced, but the wall under the window cannot be moved. This wall is called "counterweight wall" and its function is to provoke the balcony. Arbitrary removal and alteration will reduce the bearing capacity of the balcony and lead to the danger of falling.

4 doors

In order to "highlight the shape" in the decoration, many families will do a lot of demolition and transformation of the gate, destroy the building structure and reduce the safety factor. The doorframes of these "three defenses" or "five defenses" doors are embedded in concrete. If the building structure at the entrance is damaged due to random demolition and modification, it will be more difficult to install new doors.

Family indoor earthquake prevention

1, fix tall furniture to prevent people from falling. Furniture should be placed above the floor. Don't pile heavy objects on tall furniture.

2. Remove or fix hanging objects such as lamps, clocks and watches to prevent people from falling.

3. Clean up sundries to make houses, doors and corridors easy to escape in an earthquake.

4. Put the bed near the inner wall (load-bearing wall) and away from the chandelier.
