Does the window on the load bearing wall of an old fashioned brick and concrete house destroy the st

There is an idiom called "stealing beams and replacing columns", in fact, this is really used in an engineering transformation case in ancient times. You might copy one. Step 1:

Smash the lintel out first. The second step: pouring concrete lintels, side opening funnel mouth method.

It can also be used to make beams such as angle steel. Third class: After the strength of the lintel is on the job, the window is smashed under the lintel.

Construction precautions: the lintel must not be tightened on the upper wall, if the concrete is poured, it can be mixed with bulging agent. Steel beams are used, and wedges can be added at the bearings.

If you look at the thickness of the walls in the house, you can tell which one is a load-bearing wall. Destroy the structure, but there should be nothing.

This is sure to destroy the structure, you can chisel (pour) a long enough lintel above the proposed window to bear the load on the upper part of the window, and then chisel a window out.

It depends on whether there is a ring beam above the window opening, and whether it is better to have a ring beam. But you have to let go of the beam. Concrete lintels upstairs, or steel lintels such as angle steel.

Lintels must be set. My concern is not to have problems in the process of smashing. I live on 6 floors out of 7.

I'm worried that there will be no problems in the process of smashing, after all, they are all engaged in construction. After smashing, how to set up the beams, these are still understood. Including window sills and much more.

Which one has practical experience. I just wondered if there would be a problem with the smash.

Okay. Because it's done at home. It's not possible to have as much time and materials as a construction site.

For example, it is unrealistic to wait for 7 days to add bulking agents or something. Therefore, it is okay to set up steel lintels, but anti-corrosion measures should be taken, and the material is also a problem, what material is good for the 240mm just lintel?

In the general brick-concrete structure of the building, as long as it is a prefabricated panel wall, it is a load-bearing wall, and this wall can not be demolished and the door and window can not be opened, and the brick wall of more than 24 cm is also a load-bearing wall, and this wall can not be demolished and modified, and a large area of opening can not be carried out at the same time. Which walls of brick-concrete structure can be demolished? 1. The doors and windows of the counterweight wall are not demolished and modified for the brick and concrete structure of the living room, in fact, the lower wall of the house and the doors and windows can not be demolished and modified, but the door and window on the wall between the room and the balcony can be demolished or modified, which can also increase the area of our room.

2. The partition wall can be smashed for the partition wall in the living room can be demolished and modified, and generally many families will remove the partition wall and re-do the partition when decorating the living room, so that the owner can make a suitable partition according to the owner's own needs.

Summary. The load-bearing wall of the brick-concrete structure floor house cannot open the door, otherwise it will seriously affect the stability of the wall, bring potential safety hazards, and even have the possibility of wall cracking.

The load-bearing wall refers to the wall that supports the weight of the upper floor, which is a black wall on the engineering drawing, and will destroy the entire building structure if it is knocked out; The non-load-bearing wall refers to the wall that does not support the weight of the upper floor, and only plays the role of separating one room from another. The load-bearing wall is scientifically calculated, and if the load-bearing wall is perforated and decorated, it will affect the stability of the foundation.

Needs attention. What is the impact of the load-bearing wall opening hole of the brick-concrete structure floor house?

1.The load-bearing wall of the brick-concrete structure floor slab house cannot open the door, otherwise it will seriously affect the stability of the wall, bring potential safety hazards, and even have the possibility of wall cracking. 2.

The beam core load-bearing wall is scientifically calculated, and if the load-bearing wall is perforated and decorated, it will affect the stability of the foundation. Needs attention.

Now that the doors are open, what can be done?

It is necessary to take reinforcement measures to renovate the door opening into Qingyu Yuxing to ensure the stability of the structure. Usually small door openings are generally reinforced with carbon fiber and virtual transportation, or bonded steel, the advantages of these two reinforcement methods are that the construction is fast and rolling, light weight, does not increase the size of the cross-section, but can only be used in concrete structures.

The width of the door has been opened 90 cm.

Follow the above reinforcement for a while.

Question: The property rights of the house belong to the housing management center, my family lives on the west side of the neighbor, and the neighbor opened a window on the load-bearing wall on the west side of his house, and expanded it twice, and can still see everything in my house, is his behavior legal? What are the procedures of the relevant departments for the other party to open the window?

Answer: If it is not illegal, you can request to stop the infringement and restore the original state of Qihuai shooting.

24th in violation of the provisions of these measures, in the process of renovation of the building and load-bearing structure without authorization, by the municipal real estate administrative departments ordered to correct, fined between 50,000 yuan and 100,000 yuan. if losses are caused, they shall be liable for compensation in accordance with law; Where a major liability accident is caused and public safety is endangered and a crime is constituted, criminal responsibility is pursued in accordance with law.

Clause. Article 114 of the Criminal Law of the People's Republic of China stipulates: "Whoever destroys a residence, public building or other public or private property by other dangerous means, endangering public safety, and has not caused serious consequences, shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years."

In other words, the consequences of arbitrarily demolishing the load-bearing walls of houses not only bear civil liability, but may even violate the criminal law, constituting the crime of "negligently endangering public safety by dangerous means", and thus bear criminal liability.

In a brick-concrete structure, a wall with more windows and doors will affect the structural safety.

It depends on whether it is a load-bearing wall, the load-bearing wall is too dangerous to open the door, and the non-load-bearing wall can open a door. If the load-bearing wall can't open the door, girl! It's too dangerous.

In order to ensure the firmness and safety of the wall, a lintel was required on the upper celestial boundary of the door opening. If the door is wider, then it is necessary to add structural columns on both sides of the door opening. In addition, when opening the door on the brick-concrete wall, it is necessary to use a small hammer to operate, and try not to use a sledgehammer, so as not to affect the load-bearing structure of the wall.

Note that if it is a brick-concrete building, the load-bearing wall must not be dismantled, after all, the strength of the ring beam of the brick-concrete structure is relatively weak. If the load-bearing wall is dismantled, although there will be no problem in a short time, it is easy to have problems after a long time, especially in the event of ** or ground subsidence, and the degree of damage is particularly large.

Before pouring concrete for brick-concrete structures, it is necessary to clean the dust and stains on the formwork and ensure that the walls are moist. And when doing the elevation work, you need to check the flatness of the wall, if the flatness is poor, you need to repair it. When pouring concrete, it is necessary to vibrate and compact to avoid the situation of honeycomb surface, and to ensure the thickness of the plate and the flatness of the ground.

In addition, when the column is spliced, it is necessary to ensure that the verticality of the column cannot be problematic when the worker supports the formwork and pours the concrete.

The brick-concrete structure is the wall to bear the load! So you can't just tear down the wall like a frame structure!

Because of the use of functions, of course, we can open the door on the load-bearing wall, and the bearing capacity on the door is transmitted to the wall next to the door through the lintel, so we often have a common problem of load cracks in the upper corners of both sides of the door!

The size of the door opening on our load-bearing wall cannot be very large, otherwise the pressure on the door will be pressed to the wall next to the door through the lintel, and the lintel will not be able to withstand such a large load force!

Therefore, the wall that opens the door can be a load-bearing wall, and the load-bearing wall can open the door, but the proportion can not be too large, and the load-bearing wall can be compared to a lot of brick columns, and a few less brick columns are fine, if most of the brick columns are gone, the pressure on it will collapse if it is not supported!

The marked place is 12 walls, 12 walls can not bear load, can be demolished, but must be negotiated with the engineering personnel when demolition, this part is the bathroom, there may be embedded water pipes in the wall, there may also be electric wire pipes, blind demolition has potential safety hazards, in addition, 12 wall anti-overturning ability is poor, opening a hole will lead to the instability of the whole wall, and the destructiveness is still relatively large.

Now you won't notice anything, and after a while you'll see a crack in the floor and the best thing to do is to go back to the original state.

Dear, this is equivalent to making a hole in the trunk of a tree... Put steel columns at both ends, and weld steel beams on the steel columns.

Collapse! Dear, you have to pay attention!

The load-bearing wall supports the wall of the weight of the upper floor, and the load-bearing wall is scientifically calculated, and if the load-bearing wall is perforated and decorated, it will affect the stability of the foundation.

At the least, they were prosecuted.

Safety is not guaranteed.
