Can I open the window on the load-bearing wall?

Gong: According to this picture, smash a yellow on the wall for me: (Interrupting) No, big brother, the load-bearing wall will collapse as soon as it touches the beam. Gong: Don't smash it too thoroughly. Break half and leave half. Take out a closet. Gong and Huang: (in horror) Wow! ! L: Why? What are you doing? What are you doing? Gong: Sister-in-law, nothing. I just want to expand my space. Huang Hong and Gong Hanlin performed the sketch "Decoration", I believe you can still imagine the scene at that time. Then can the load-bearing wall open the window and open the door?

Problems of Miss Fubangzhuang in Changning

The house is an old house, and the light is quite dim. I want to open a window on the wall. The invited master said that the load-bearing wall can't be removed, but someone said that it can be removed, so I want to ask the supervisor if I can open the window.

Supervising and answering questions

Now more and more owners are not satisfied with the layout design of the original developers, and all want to pursue a unique style. In order to pursue perfection, they will change the indoor structure at will. In fact, this practice is not desirable. Owners must be clear about the indoor housing structure, especially the load-bearing wall, because the load-bearing wall cannot be changed at will. Dismantling the load-bearing wall, opening doors, opening windows and thinning the load-bearing wall will not only directly damage and weaken the load-bearing capacity of the load-bearing wall, but also damage the integrity and seismic capacity of the house. If you must open the window, you must ask a professional construction team to operate with the consent of the property.

First, how to distinguish between load-bearing walls and non-load-bearing walls?

1, function

Bearing wall: Bearing wall refers to the wall that supports the weight of the upper floor. It is a black wall on the engineering drawing, which will destroy the whole building structure after being knocked out.

Non-load-bearing wall: Non-load-bearing wall refers to a wall that does not support the weight of the upper floor, but only separates one room from another. There is a hollow wall on the engineering drawing. Whether this wall has much influence on the building structure.

2. Building structure

Generally speaking, the walls of brick-concrete buildings are load-bearing walls.

Generally, the wall inside a house with frame structure is not a load-bearing wall, but there are exceptions, because judging whether the wall is a load-bearing wall can only be determined after carefully studying the original architectural drawings and the actual site reconnaissance.

3. Distinguish from the wall brick material.

General standard walls are load-bearing walls, while aerated bricks are non-load-bearing walls.

4. Thickness

From the wall thickness: 150mm thick partition wall is a non-load-bearing wall, such as bathroom and kitchen. Generally, the thickness of load-bearing walls of newly-built apartments is above 300 mm.

5. Distinguish the junction.

According to the distinction between beam and wall, generally, the wall closely combined with beam is a bearing wall, and the method of obliquely arranging bricks is a non-bearing wall. Walls can be divided into horizontal walls, vertical walls, mixed vertical and horizontal walls and local frame walls.

The outer wall and the wall used with neighbors are load-bearing walls, and it is very dangerous to dig holes in this wall, while the partition walls of bathrooms, storage rooms, kitchens and aisles at home are mostly non-load-bearing walls.

6. Listen to the sound

Usually, the easiest way to identify a load-bearing wall is to knock on the wall by hand. Non-load-bearing walls have clear echoes, but the sound heard by knocking on the load-bearing walls is basically dull.

Second, can the load-bearing wall be perforated?

1, generally speaking

In the process of home improvement, it is forbidden to open holes in the general load-bearing wall, which is not only illegal, but also risky, because the load-bearing wall bears the weight of the house. If it is demolished or opened, it will lose its original function and reduce the seismic performance of the wall. In design, the force is evenly shared by all parts of the wall. When the local wall is demolished, the shear force acting on the wall during the earthquake will be the same as that acting on the adjacent wall, resulting in overload of the adjacent wall or stress concentration near the hole.

2. Special circumstances

If you must make a hole, it is not completely impossible, but the following factors should be considered.

The Ministry of Construction stipulates that if the load-bearing wall is to be rebuilt, for example, the original design unit or a design unit with the same qualification as the original design unit can give a modified reinforcement design plan before the load-bearing wall can be demolished.

In other words, from a technical point of view, you can also open a window; But it must be reduced within a certain range, and the reinforcement should be completed. The commonly used reinforcement methods are as follows. Sticking steel or carbon fiber, etc. However, this reinforcement scheme and demolition work must be completed by qualified units, and channel steel must be embedded if the property permits, and the windows should not be too big.

Secondly, I suggest that you don't tear down the load-bearing wall at will. On the one hand, it is not an easy task to dismantle and change. Secondly, in many aspects of design, if we don't pay attention, it will destroy the building structure, cause security risks and even be complained.

Noun interpretation

24 Wall: Architectural proverbs refer to a wall with a width of 240mm, because the width of the current wall brick is generally 1 15mm, and the sum of two bricks is 230mm, plus 10mm mortar joint, which is * * * 240 mm. Therefore, it is called 24 Wall.

Load-bearing wall: in general brick-concrete buildings, all prefabricated walls cannot be removed or opened; Brick walls over 24 cm are also load-bearing walls.

property management company

It is not the water and electricity supplier stipulated by the relevant national policies, but the residential community is the object of comprehensive services provided by the relevant departments. All departments should carry out their duties in accordance with the relevant policies and regulations, and cooperate with each other to provide services for the community as the owner. Water and electricity are provided by water and electricity suppliers. According to the regulations, suppliers should read meters at home and charge by measurement. Unless formally entrusted by the hydropower department, the property management company does not need to charge for the hydropower department, nor does it need to bear the responsibility of natural loss of hydropower.

Have no right to win the world.

Property companies are enterprises, not functional departments, not the government. The task of an enterprise is to produce products, serve customers and create benefits. As far as property management enterprises are concerned, their products are services, their customers are owners, and their service items, scope and standards are defined by contracts that are equally binding on both parties. In the execution of the contract, you can neither be absent from the position nor offside, and you must perform the contract according to the principle of "entrusted, contracted and paid service".
