In the home decoration, because of the design needs, it will inevitably require knocking on the wall. For wall-cutting, you may not be familiar with it yet. The so-called wall-to-wall excavation is the demolition and reconstruction of the wall surface of the original house. So, what are the steps and the focus of attention for knocking on the wall? Does the wall need to go through certain procedures and procedures? What do the owners need to do during this period? Below, we learn together with Xiao Bian!
The meaning of knocking on the wall:
The knocking on the wall is also called the demolition of the wall. It is to demolish or excavate the part of the wall that was originally built in our house, because you have to change the position of the room or the size of the room, so you have to demolish the previous wall. This is the wall knocking.
Steps to knock wall:
1. Before dismantling, consideration should be given to whether or not the neighbors are to be renovated. Whether or not the neighbor will be affected when dismantled. Otherwise, you will make a hole in the wall and the ladies Lin Yi-Jian in the "Renovation" comics will come to your home and you will be upset by the sky!
2. Determine the wall surface that can be dismantled. First use a cutting machine to cut the stucco layer that needs to be removed.
3, the best use of hammer drill gradually removed, do not blindly use a sledgehammer, so as not to affect the excessive vibration of the wall and neighbors do not need to be dismantled.
4. After dismantling, check whether the adjacent wall surface is affected. For example, if the powder layer leaks, empty drums, etc., it shall be removed at the same time and refilled.
5. When re-building a wall, the weight of the ground should be considered. When there is no special requirement, lightweight materials should be used as much as possible.
Wall-cutting considerations:
1. The top beam is not removable:
When some owners renovate, they feel that the beams on the top of the house affect the appearance and they intend to knock out the protruding parts of these beams. In fact, the beams in the middle of the house must not be knocked on. Because the beams support the upper floors, knocking on the walls or transforming them will cause the upper floors to fall.
In addition, it should be noted that if some beams are connected to the top of the wall, they can only hit the bottom of the beams when knocking on the wall. For example, the site must knock out the wall between the bedroom and the study. However, there are beams above the wall. This area cannot be moved. Otherwise, there is a safety hazard. When you encounter a beam, you cannot knock it. You can use the ceiling to hide the beam. It will not affect the appearance.
2. Do not knock on the wall of the balcony:
In order to improve the lighting of the room, some owners knocked out some of the walls connecting the balconies to increase the width of the balcony door. This is not allowed. Because the exterior walls of the house are usually load-bearing walls, it is very dangerous even if you open the windows above.
In addition, on some walls between the room and the balcony, there was originally a window, and the doors and windows could be knocked, but the wall below the window could not be knocked out. The wall of the window line is called the "counterweight wall" and it acts as a balcony. If the wall is removed, the bearing capacity of the balcony will drop, causing the balcony to fall.
3. It is forbidden to remove the bearing wall:
In the renovation, the load-bearing wall cannot be changed and many people know it. But what kind of wall is a load-bearing wall, not many people can make it clear. The load-bearing wall is a wall with no pre-fabricated beam on the wall. The thickness of the wall of the load-bearing wall on the floor plan drawing is obviously thicker than that of the non-bearing wall. The thickness of the solid wall is generally 24 cm, and the non-bearing wall is 10~ 15 cm. The outer walls are usually load-bearing walls, and the walls shared with neighbors are also load-bearing walls. Generally non-load bearing walls are in bathrooms, storage rooms, kitchens and aisles.
In a word, the transformation of the house structure to demolish the wall will inadvertently affect the structural safety of the house. If the owner is to carry out the transformation of the house structure, he will need to look at the design drawings of the construction structure, look at the load-bearing walls, and consult the relevant professionals before proceeding with the construction.
4. Repair work after wall removal cannot save:
The wall is knocked off safely, but the later repair work can not be ignored. For example, if you knock off the original wall and use red bricks to build new walls, you will need to set up reinforcements on the newly built walls. “Lajin†is the construction method for the joints between old and new walls. It is to pull new and old walls with steel bars to ensure the stability and shock resistance of the walls.
In addition, openings are made in the wall, and a reinforced concrete "beam" is erected above the door opening. This can share the pressure of the wall above the door opening and prevent the pressure above the wall from directly pressing on the door frame.
The main preparations for this step are:
Before the wall is demolished, it should be reported to the property for approval: In general, when the building is completed, the original design unit will leave a drawing for the property company. The thickness and material of various walls, such as load-bearing walls and non-bearing walls, are clearly indicated on the drawings. According to the drawings, the property company can determine which walls can be knocked on. Therefore, the owner must submit the construction drawings given by the designer to the property company before the wall is reconstructed.
