It is clearly stipulated in the bearing wall that the bearing beams and columns can be drilled. Will the house fall down if the bearing columns are drilled?

when decorating a house, it is generally necessary to punch holes in the wall, so as to facilitate the installation of things later. However, I believe many people don't know the regulations on punching holes in load-bearing walls. Let's take a look at the clear provisions of punching holes in the load-bearing wall with Xiaobian. By the way, can the load-bearing beams and columns be drilled and will the house fall down when the load-bearing columns are punched? Let's take a look at it with interested friends.

1. Explicit provisions on punching holes in load-bearing walls

1. According to the explicit provisions on punching holes in load-bearing walls, load-bearing walls can be punched. However, the load-bearing wall is a structural frame that carries the weight of the house. Therefore, if the bearing wall needs to be perforated, it needs to be carried out in strict accordance with its regulations. In the building code, there are requirements for the location, size and quantity of bore holes in load-bearing walls. It must not destroy its original structure.

2. In decoration, it is generally suggested that the bearing wall should not be moved as much as possible. If it can be punched in another place, yes, if it is not, then choose the bearing wall. The punching construction of the bearing wall must be carried out by professionals.

3. Techniques for punching holes in load-bearing walls

(1) Before punching holes in load-bearing walls, we must first understand the intention of each hole, the structure of the building and the internal and external conditions;

(2) clearly mark each hole position, and observe the trend of water and electricity pipelines;

(3) punch holes in the load-bearing wall as far as possible on both sides of the beam, and the stress on both sides is small;

(4) punch holes in the load-bearing wall as far as possible on the beam with the wall below;

(5) punch holes in the load-bearing wall as far as possible at the top of the beam, and the stress on the top is small;

(6) Try to make small holes in the beam.

2. Can bearing beams and columns be drilled?

1. Can bearing beams and columns be drilled? Some load-bearing beams cannot be perforated. If the diameter of the hole is less than 1 mm, you can safely punch holes in the load-bearing beam without worrying. Generally, the punching position can be selected in the middle of the girder or near the neutral layer. If the diameter of the hole is greater than 1mm, it is usually not allowed to punch holes in the load-bearing beam, which has potential safety hazards. However, if the hole must be punched, the location of the hole needs to be approved by the property.

2. The load-bearing beam is the beam used to bear the load in the house, and it is the pillar of the whole house. Generally speaking, it can't be dismantled and changed. Load-bearing wall refers to the wall supporting the weight of the upper floor, which will destroy the whole building structure.

3. Will the house fall down if the bearing column is perforated?

1. Will the house fall down if the bearing column is perforated? If only a hole is punched in the load-bearing column, generally speaking, the house will not fall down, but if a steel bar is broken, it will definitely affect the structural safety of the house. When designing a house, there is a safety factor, which is generally about 2 times. These safety factors have taken into account the deviation of the quality of construction materials, the deviation of construction technology and the man-made small damage during use. Because the column is a compression member, it will not collapse when the house is at rest.

2. If it is in cast-in-place construction, there must be some strengthening methods in the construction process. First of all, we should consider the temporary reinforcement of the load-bearing beam. For example, temporary supporting objects can be added under the beam to ensure that the quality problem will not continue to develop and cause other losses. Then, entrust the original design unit or a design unit with corresponding qualifications to do structural reinforcement design. At this time, it is necessary to issue the design documents signed by the structural engineer and the design institute. Then, the relevant units can take appropriate measures to reinforce the load-bearing beams.

The above is the clear stipulation about the punching of load-bearing walls, whether the load-bearing beams and columns can be drilled, and whether the house will fall down if the load-bearing columns are punched. I hope it will be helpful to everyone!
