How should decoration supervisors supervise? Workers can’t go there every day. They go there less times and are afraid that workers will fool them.
In fact, there is no need to go every day, just keep an eye on it at a few key moments. As for when to go, how to look at, and where to look, I have sorted it out for you, which can save you at least 80% of your time!
remove
, sewer pipe protection
There are a lot of small stones, mud and other debris during the demolition and modification stage, which can easily fall into drainage pipe , causing blockage. The sewer entrance should be covered with a protective cover to prevent debris from falling off.
, shovel wall skin
Remove wall and ceiling paint, that is, shovel big white. Use to scrape to remove the paint from top to bottom, from left to right, and until the cement layer is exposed. Some workers just shovel at will, and don’t clean it, and they will easily peel when painting.
. The junction of new and old walls
The inside of the new and old walls junction, and the old walls should be implanted in the old wall every 60cm. When plastering on both sides, the new wall junction point needs to be laid with a steel wire mesh of no less than 15cm in width, that is, hanging net , and then smear with cement mortar to increase the stability of the new and old walls. Otherwise, the latex paint at the junction is prone to cracking and falling off.
In addition, generally speaking, only needs to be reinforced at the junction of new and old walls, and no other walls are needed. If the decoration company or foreman proposes to hang a whole house network, it is likely to be a waste of money.
. New wall
Use light brick to build a new partition wall. The standard method is to use small bricks on the top to make centipede feet , the middle is horse teeth rub style, and the bottom is small bricks of no less than 3 layers of as floor pillow .
▼The following figure is a very standard light body wall masonry method. If you save it, you can refer to
hydropower
, water and electricity pipe
water pipe electric pipe different tanks, hot and cold water pipes different tanks, and strong and weak wires different tanks. wire tube generally has color distinctions, such as water pipes use green, strong electricity use red, weak points use blue, just look at whether there is only one color wire tube in a slot.
, strong and weak current transfer
strong and weak current intersection wrap the tube with tin foil to prevent signals from interfering with each other.
. Wire wire head protection
socket bottom box must not have exposed wire heads. All wire heads should be wrapped with insulating tape to avoid the risk of electric shock.
▼ Wrong method, wires are exposed
▼ Correct method, wires are wrapped with insulating tape
, internal
1 The total cross-sectional area of the wires in the tube shall not exceed 40% of the cross-sectional area in the tube, avoiding affecting heat dissipation. Generally speaking, 5 2.5mm wires are almost 40% in the 4-point tube.
. Count the wires in the tube. There are 3-5 wires, and there is still a lot of space left, which means that they meet the standards. or eight tucked together, obviously stealing the owner's materials. There is only one wire in a tube, which wastes material.
There are the most tricks in water and electricity, so let me know more here.
The different billing methods are different, 1) The price is a waste of money: workers may replace the materials to make up for them, or plug eight or nine wires into a tube to take away the remaining materials. 2) Calculate based on the actual project volume, you may increase points and winding in different ways, and use more materials to charge more money.
Choose a way to save money at a price. Work harder yourself and start supervising the work from the day the materials enter the site. Ask more advice, less suspicion, and avoid workers from tampering with them.
optionally billed according to the project volume. The decoration company must make the water and electricity price estimate in advance and sign an supplementary agreement . For example, if the total water and electricity price is agreed not to exceed 5% of the estimated amount, the excess will be borne by the decoration company.
Regular decoration companies will accept water and electricity supplement agreements, and you can also focus on this when choosing a construction party. You can first check the ranking of local high-quality decoration companies, do a screening, and then choose a few to compare according to your own budget and needs.
. Pressure test
After the water pipe is laid, first performs a pressure test and then bury to ensure that the water pipe does not leak. After the water pipe is installed, wait at least 24 hours before testing. Apply 8 pressures and let them stand for about 40 minutes. The pressure drops no more than 0.5kg, which means you are qualified. Then carefully check whether water seeps in the water pipe surface, especially at the connection.
tile
0, bathroom backfill material
Before backfill, waterproofing should be done on the base layer. Construction waste, that is, construction slag, has sharp edges and corners and unevenness, which can easily pierce the waterproof layer, resulting in water leakage in the bathroom. It is recommended to use carbon slag or ceramic granules for backfill materials, which has good water absorption and a smooth surface, and will not break the waterproof layer.
Some workers are too lazy to clean up the walls and windows to smash the stones and other debris on the construction site. They will directly backfilling them into the bathroom, which will be covered up and the owner will not be able to find out. Therefore, it is recommended to attend the supervisor in person.
▼Construction waste backfill,
▼Ceramic grain backfill,
1, package riser
Before sealing the sewer pipe with a keel or light brick, you must first use sound insulation cotton or gold damping to wrap the pipes to play a role of sound insulation. Some workers want to save trouble and ignore the step of sound insulation material and directly guarantee it. The consequence is that the sound of the neighbors flushing in the toilet on the upstairs will be heard from home.
▼ Before laying bricks, wrap soundproof cotton. In addition, remember to leave a maintenance port .
2. Waterproof height
Waterproof floor at least twice waterproofing. The minimum height on the wall should be 30cm. The shower area should not be less than 180cm. The exterior wall should also be 30cm.
3. waterproof test
3. waterproof test
Waterproof test 24 hours after completing the waterproof test. Remember to notify the neighbors downstairs in advance. Put water at a height of about 2cm in the bathroom, observe it to see if the water level has dropped significantly for 24 to 48 hours, and go to the home downstairs with the property to check whether there are any signs of water seepage. If everything is normal, it proves that the waterproofing is done well and the acceptance is passed.
closed water test is a must-do project. No matter whether you are looking for a decoration company, a construction team, or even your father helps with the decoration, you cannot save it. If this item is not on the quotation of the decoration company, you can basically consider changing one.
4, drainage slope
1, bathroom drainage is not just about the floor drain, the key lies in the ground slope . This slope must be manually found by workers when laying tiles on the ground. The slope is generally around 1%. and place the floor drain at the lowest so that the water can flow in the direction of the floor drain and enter the sewer pipe.
After laying the floor tiles, take a ping-pong ball or several marbles to check. If you roll in the direction of the floor drain and stay near the floor drain, it means that the slope has been made.
If you have a shower room, it is recommended to make slopes inside and outside the shower room and install floor drain , otherwise there will be water accumulation outside the shower room.
▼ For example, the floor drain should be placed at the lowest point
5, floor drain
In addition to the overall slope, the tiles where the floor drain is located should also have a small slope. Generally, the tiles where the floor drain is located should be cut into a back shape, are low in the middle and high in the surroundings to ensure that water in different directions can be discharged into the drain pipe along the cutting surface of the tiles.
▼ Correct method: Cut floor drain tiles into a back shape
▼ Wrong method: There is no slope of the tiles at the floor drain
6, tiles are laid
6, and tiles are laid
There are also differences between "true and false". The tiles are laid out very much, because they save threshold stone . You must strictly layout and cut to lay a whole brick at the door, and the tiles must be well-liked.
▼ Fake and the tiles at the door are cut into several small tiles, which is not as good as the sill laying stone
▼ Really, the whole tiles are visible when opening the door, completely match the seams. The master's skillful
carpentry
6, floor protection
After the tiles are laid, the floor protective film should be laid to avoid scratching or smashing the tiles in the woodworking stage ceiling keel and other materials.
7, keel spacing
Large area ceiling recommended to use light steel keel , which is more stable. The spacing between the keels is 80-120cm, and the spacing between the secondary keels is about 40cm.
8. After the gypsum board splicing
keel frame is built, the gypsum board is sealed. The junction of the gypsum board should be spliced into "V" shape to facilitate the oil worker to caulk and patch the joints, and then paste kraft paper to avoid cracking at the splicing.
9. The corner of the gypsum board is the concentration point of stress and the place where cracks are most likely. The corner of the gypsum board should be cut into the shape of "L" and and ensure that it is whole board to avoid cracking due to splicing.
▼ Correct method, L-shaped board
▼ Wrong method, the corner is the splicing board
Oiler
0, cabinet protection
Before painting, cabinets, furniture, etc. that have entered the site should be protected to avoid paint splashing on it and it is difficult to clean it.
1, scraping putty
, scraping putty mainly flattening the wall, filling the bumpy areas, and then applying latex paint. Generally, putty should be scraped 3 times, and there should be no scratches, trachoma, unevenness, etc., otherwise it will cause cracks on the wall or small stains.
▼ There is trachoma at the corners
2, latex paint
If the operation is improper, such as applying paint on rainy days or when the wall foundation is relatively humid, it will cause cracking, peeling, blistering and other phenomena of latex paint.
For example, the vertical lines on the wall can be seen with the naked eye, and will be more obvious under the light. It is best to rework and rework.
