The house is going to knock on the wall. What materials do you need to bring for security check? What are the steps?

Houses have to knock on the wall. If you are going to do security check, you need to bring your ID card, relevant certificates of real estate, load-bearing structure diagram and schematic diagram of knocking on the wall.

Precautions for knocking on the wall of the house:

Never touch the load-bearing wall, even if you dig a big hole in it, otherwise the consequences will be very serious. There is also a wall under the balcony window of the old house called the counterweight wall, which is used to balance the gravity of the balcony and has a certain bearing effect on the balcony, so it is best not to tear down the old house. However, if the windows and brick walls are removed together, some property companies will allow it, mainly depending on the specific situation of the building. ?

Compared with the load-bearing wall, the non-load-bearing wall bears at least two parts of load, one is the self-weight of the wall. Take a six-story residential building as an example. The non-load-bearing wall of the residents at the bottom floor should bear the weight of the above five layers of walls, and each meter-long wall should bear the weight of 7300 kilograms. Secondly, from the structural point of view, non-bearing walls are often seismic walls in design. In other words, when an earthquake occurs, these non-bearing walls will bear the earthquake force together with the seismic walls. Reportedly, this kind of non-load-bearing wall can't be dismantled generally. Although it is not a big problem for a single family to tear down a non-bearing wall or make a hole in the wall, if the residents of the whole building tear down and change the wall at will, the seismic capacity of the building will be greatly reduced.

There is also a kind of wall, that is, the wall that rises in a long-span place after the building is completed. Structurally speaking, this kind of wall belongs to non-bearing wall, but it plays a great supporting role in the house and cannot be demolished at will.

In addition, for the non-bearing wall under the concrete beam, we can't act rashly. Although the beam is made of concrete, it does not directly bear the vertical load of the weight of the floor and wall above the beam, but is transferred to the wall below, so the beam itself does not add much steel. Therefore, once the wall under the beam is removed, the beam will lose its supporting force and gradually deform or even collapse.
