After receiving the house, the decoration and hard decoration construction really began.
The first step is the demolition and modification of the main body, which to be demolished, which to be newly built, all completed at this stage.
The main body demolition is the most noisy stage in the entire decoration process, but also the most "violent" stage, mainly including the demolition of the wall, the building of the wall, the shoveling of the wall skin, the demolition of heating, the replacement of the window, etc., depending on the size of the home engineering, this stage will last about 5-7 days.
Part I: These places cannot be moved
1. Load-bearing wall
The load-bearing wall bears the heavy responsibility of safety and stability of the entire building.
Some owners don't think so, think that the whole building so many households, so many load-bearing walls, I will tear down this wall of my home, how much risk can it be? There is even an unscrupulous construction team in order to meet the needs of the owner, patting the chest and guaranteeing to the owner that it can be demolished, no problem!
I just want to ask, is this house where you live or the construction team? Something goes wrong later, is it you or the construction team that suffers? Such an unscrupulous construction team, even if you want to settle accounts after the autumn, you may not be able to find someone.
There are also many people who know that the load-bearing wall cannot be demolished, but some people have a sudden idea, I do not dismantle it all, I will dismantle half of it, and open a window to see through the light? No way!
This will damage the structure of the load-bearing wall, and the safety hazards are endless!
Therefore, for our own safety, everyone still abides by the law and does not move the load-bearing wall!
How to tell if it is a load-bearing wall? This is more complicated, and the load-bearing walls of different structures of houses look different, for example, the load-bearing walls of brick-concrete structures and frame structures are not the same.
The most secure way is to ask the property for the floor plan, and the standard floor plan will be marked with black to mark the location of the load-bearing wall.
If there is really none, it can be judged by the thickness of the wall, and generally the walls above 24 cm are load-bearing walls.
2. Light body wall under the beam
Many people know that the load-bearing wall cannot be moved, but can the light body wall be able to move? not necessarily!
Some light walls also bear part of the weight of the house. For example, the light wall under the beam cannot be removed.
Because it also bears part of the weight of the house. If demolished, it will destroy the structure of the house. The light body wall and hollow board that are completely used as partition walls can be removed. This kind of wall does not bear any pressure at all, and the value of existence is to separate the space, and demolishing it will not have any impact on the structure of the house.
3. Low wall by the balcony
Some houses have balconies with doors and windows, which can be removed, but the low wall under the window cannot be demolished.
This section of the wall is called the "counterweight wall", and it plays the role of provoking the balcony. To put it simply, this low wall is similar to a scale, used to press the balcony, dismantle and modify the wall, resulting in a decrease in the bearing capacity of the balcony, and the balcony will have the risk of falling.
Look at the news, chop a dumpling at home and chop off the whole balcony.
4. Beams
The beams and columns in the room cannot be changed. Beams and columns are used to support the upper floor slab, demolition or transformation will cause the upper floor slab to fall, quite dangerous, so the beam and column must not be demolished or transformed.
5. Reinforcement
When slotting the line, it is best not to cut the reinforcement, if the rebar is destroyed when the pipeline is buried, it will affect the endurance of the wall and the floor. In the event of an earthquake, such walls and floors can easily collapse or break.
Part II: Do you want to shovel the wall?
Before we know whether to remove the wall, let's briefly look at the structure of the wall paint construction. Covering the outside of the wall, there is plaster, putty, and the surface of the putty is the paint.
Plaster and putty are generally used to find flat walls, and putty must be scraped before painting. The putty is also divided into water-resistant and non-water-resistant types, water-resistant putty has better water resistance and corrosion resistance needless to say, the service life is longer than non-water-resistant putty. Whether to remove the wall depends on the specific situation.
1, if your wall, need to paste tiles like kitchen and bathroom, balcony these places of the wall, the follow-up will generally involve the wall tiles, regardless of whether the wall is used water-resistant putty, you need to shovel the wall skin clean, and then paste the tiles.
2, if you do not need to paste the wall of other spaces of the tile, it may not involve the tile, whether to eradicate the wall at this time, it depends on the situation of the original wall.
3, some houses, the putty used on the wall, are not water-resistant putty, at this time you need to shovel the wall skin clean, and then re-treat the wall. New houses, the wall is mostly used water-resistant putty, at this time if the wall is relatively well preserved, no mold, no empty drum, the wall putty can not be eradicated.
Some people may need to paste wallpaper on the wall, at this time also depends on the error of the wall, if the error is too large, you can only shovel off the original wall skin and re-do the flatness treatment.
To what extent is the shovel qualified?
The new house needs to be shoveled to the cement mortar layer, and if the wall of the old house is too loose and the empty drum reaches more than 10, it needs to be shoveled to the red brick layer. When shoveling, it is a full-area removal, including the position of the skirting board, to prevent the decorative material from falling off in the later stage.
How do you see what kind of putty is used on the wall?
1, sprinkle some water on the wall, and then use your fingers to knead it, if you can knead out the white pulp, it is generally a putty that is not resistant to water, which must be eradicated.
2, you can also try to use a shovel to shovel the wall, if it is easy to shovel down, generally also the use of non-water-resistant putty, need to be all eradicated.
Part III: Should the floor tiles be demolished?
Some people think that this problem is redundant, it has been redecorated, why not demolish? But in fact, there are often owners who consult with Xiaoqi, and the floor tiles can not be demolished, because it costs a fee to dismantle, and it is necessary to install another cost.
If the floor tiles are better preserved, they can still be used, in fact, there is really no need to take great pains to remove them, but we must do a good job of finished product protection.
If you are ready to lay composite flooring, in fact, you can also consider not demolishing the floor tiles, directly laying the wooden floor on the tiles, but this practice requires the flatness of the original tiles to meet the needs of paving the wooden floor, and the empty drum rate of the tiles cannot be too high.
In addition, directly laying wooden floors on tiles will sacrifice a certain height, which depends on the situation in your own home.
Part IV: In addition to demolition, there is also construction
Although this stage is called the demolition and modification of the main body, there is another work that is also carried out at this time, that is, the new wall.
Now the home decoration of new walls is generally used are light bricks, gypsum board is generally used in rented houses to break partitions, red bricks are not to be used, heavy and thick, increasing the burden of the floor and occupying land.
There was once an owner who reacted with Xiao Qi, his family was ready to use red bricks to build a new wall, and the downstairs neighbor came to him, saying that the floor slabs of the entire building were thin, and what if the floor collapsed with such thick bricks? The neighbor even brought a scale, weighed the bricks, calculated the weight of the entire wall, and resolutely refused to use red bricks. Although this neighbor is a bit exaggerated, but for the sake of neighborhood relations, it is better to use light bricks.
New walls are not as simple as we build blocks, and there are some problems to keep in mind:
1. The light bricks used in the new wall need to be soaked in water until they do not bubble. The first layer of bricks needs to be implanted with steel reinforcement, and then every two layers after that. The reinforcement must not only penetrate the wall, but also be implanted in the connected wall.
2. After the wall is built, it is necessary to hang a barbed wire mesh on both sides and then smear cement mortar.
3, if there is a door opening, you also need to do the door beam;
4, the new wall if you want to paste the tiles need to be built in advance after a week or so, brush paint, it takes longer, generally summer is about 30 days, winter is about 45 days.
Final matters:
1, the demolition stage must protect your home sewer, demolition will inevitably have sand and gravel will enter the sewer, there are some bad businesses directly throw construction waste into the sewer, and so the owner of the house to move in will find that the home sewer for three days at both ends, disturbing the heart;
2, the demolition of the garbage clearance freight to negotiate with the business, the general decoration company said that the free removal of garbage is generally only transported to the designated location of the community property, excluding garbage transportation, garbage transportation is generally the property responsible, decoration to start the formalities, you can pay the property related fees.
