Do you not know the "minefield" renovation?

When determining whether a wall structure can be modified in the end, do not consider it from an aesthetic point of view, but consider from a safety point of view that if there is a safety hazard in the demolition of the wall structure, it must not be adopted and implemented. What are the "minefields" in the renovation and renovation projects?

What are the "minefields" in the renovation and renovation?

Minefield 1 bearing wall

As the weather gets warmer, more and more renovations are coming into play. After entering the market, it was the demolition of the wall and the laying of pipelines. In the process of demolishing the wall, many owners often prefer to remove the load-bearing wall in order to complete the decoration of the house. This is a very undesirable practice.

In a general brick-concrete structure, any prefabricated wall is a load-bearing wall that cannot be removed or opened. Brick walls above 24 cm are also load-bearing walls. The load-bearing wall must not be moved during the renovation, and it is not enough to have a large hole on the top.

Tip: Removing the load-bearing wall, opening the door, opening the window, and thinning the load-bearing wall on the load-bearing wall not only directly damages and weakens the carrying capacity of the load-bearing wall, but also destroys the integrity and seismic resistance of the house. It may also cause cracks in the adjacent walls to loosen, weaken the wall strength and bearing capacity, and crack the upper and lower walls and floors, causing structural damage. In the event of an earthquake, such walls and floors can easily collapse or break.

Minefield 2 gas pipeline

It is very easy for residents or decoration personnel to dismantle gas pipelines and enclose gas valves without permission. Gas pipelines are enveloped, gas leaks are not easily noticeable, and leaked gas is not easily diffused and accumulates locally. Before use, there is no professional safety test. In case of a fire, it will inevitably cause an explosion.

Tip: There are strict technical specifications and safety requirements for the design and installation of gas facilities. Construction must be carried out by professionals. If residents need to modify the gas pipeline when decorating the living room, they should apply to the gas supply unit. The gas supply unit should carry out on-site survey and put forward opinions. If it can be modified, the gas supply unit should issue a construction plan and be operated by professional personnel. Should have professional qualifications.

Minefield 3 Heating Pipeline

What are the "minefields" in the renovation and renovation?

During the renovation, the heating pipe was demolished and changed, and the situation of the upper and lower water pipes was also more common. Heating pipes and upper and lower water pipes all have a common feature, that is, these pipes form an overall system within a certain range, and each household cannot be completely independent. Therefore, when such a pipeline is reconstructed, care should be taken to ensure that all modifications are done without affecting the entire system.

Tip: There are many drawbacks to dismantling the heating system indiscriminately. After the originally designed heating is changed, the pressure will change. After the heat balance is broken, the heating will be misaligned, causing the houses to be hot and cold. After the change of heating, it is difficult to ensure no water leakage.

Lei 4 balcony "weight wall"

There is a window on the wall between the general room and the balcony. The doors and windows can be dismantled, but the wall below the window cannot be removed, because this wall is a “counterweight wall” and it acts like a scale to lift the balcony. effect. Many owners think that the role of weight wall is not great, blocking the sun from entering the room, affecting the room's lighting. Therefore, it is often considered to demolish the counterweight wall and form a large cornice at the balcony.

Tip: Demolishing the counterweight wall will reduce the bearing capacity of the balcony and cause the balcony to fall. Demolition of the counterweight wall will change the original structure of the house structure. It may also lead to a reduction in the load-bearing capacity of the balcony and even the risk of collapse. Some old houses have a terraced structure. Once they are dismantled, the wall structure that “presses” the balcony is destroyed, weakening the bearing capacity of the balcony.
