Anonymous users2024-01-24Is it a crack close to the root of the wall parallel to the wall? If so, it is because the board is against the wall and forgets to match the negative reinforcement (that is, the reinforcement on the top of the board, which is also called gluten).
Reinforcement is a bit cumbersome. If it is convenient, the bottom of the slab can be cleaned, and 10 mm steel bars can be bonded with construction glue at the bottom of the slab, with a spacing of 150 mm, and 20 thick cement mortar can be smeared. But this requires a professional team to carry out the construction.
Then after the bottom of the slab is reliably supported, the top of the slab is dehaired, rinsed, and the steel mesh with a diameter of 200 mm and a spacing of 200 mm is laid, and 40 mm of fine stone concrete is poured, and the support is removed after the age is reached.
It is also possible to add a beam at the bottom of the slab, which can save some money, but the construction is not easy.
Finally, it is recommended to invite a professional architectural structure designer to come to the site to see, if it is a dry shrinkage crack, it is easy to do, and the seam can be flattened. It is not a dry shrinkage crack, and it needs to be dealt with by professionals when it needs to be reinforced. You can't do it yourself.
If you don't want to knock out the re-pouring, you have to change the layout of the original room and add a wall in the middle (this wall also needs to be laid.
Around the ceiling to buy their own materials no more than a few hundred (the material is good, the carpentry union will bill you, generally will tell you where to buy), carpentry is generally about 50 meters (by meters), depending on your city's labor costs are expensive, hang the ceiling to buy lights, lights are expensive, because now are LED lights, good looking and power saving, but the early investment is large, my home has just been installed, friends introduced in Dongguan Cheng Teng Electronic Technology Co., Ltd. to buy LED light strips and spotlights, two years, very good, the price is relatively acceptable, to show you the renderings of my house, hehe.
On one of the walls, you can paste a good-looking background wallcovering, and the effect is completely different.
If it is a ceiling made of light steel keel, it will not be deformed if it is soaked by seepage, in this case, the putty that falls off the surface will be removed, and the putty can be scraped and painted again; If it is a ceiling made of wooden keel, the wooden keel will be deformed after being damp, which will then affect the deformation of the ceiling. >>>More
You can choose different colors as decorations, or you can light different colors, so the effect is also good.
