How to decorate?
Effective supervisor?
1) staring at the demolition.
1. The main point is not to disassemble or damage the sewer;
2. Shovel the wall and observe whether it is completely removed. Be sure to see the cement wall;
3. See if the demolished wall is cut straight. You can't get through if you dig seven and twist eight dogs;
4. Block the sewer pipe at the first time, and block it with a special cover or rag, otherwise the stone chips will fall in and easily cause blockage;
(2) Inspect the materials entering the site.
1. When the decoration materials enter the site, the owner must be present for acceptance;
2. Take the decoration quotation as an example, check whether the quantity/brand/model/specification/size and functionality of the materials are purchased by yourself at the beginning to prevent the decoration company from cutting corners and shoddy;
(3) Water and electricity disclosure
1. The commencement disclosure is very important, and the owner must be present;
2. Water and electricity disclosure Before the start of water and electricity decoration, the householder will explain it clearly to the decoration company;
(4) staring at backfill.
1. When backfilling toilets, workers must be prevented from backfilling with construction waste, which may lead to the destruction of waterproof layer and water leakage.
2. It is suggested to choose the way of overhead, just build a high brick at the bottom of the bathroom, and then lay a layer of cement board.
⑤ Pay attention to the direction of water and electricity trunking.
1. Construction personnel use tools to locate elastic lines and determine the positions of switch sockets, lamps, etc. The scene.
2. Slotting must be horizontal and vertical, and it is easier to rebuild the house after decades of decoration.
3. The load-bearing wall cannot be slotted horizontally! Non-bearing walls can be slotted horizontally, but not more than 50cm.
Never draw diagonal lines when slotting in the wall.
If the slot is wrong, we must put it forward on the spot. According to our living habits, we can leave as many sockets as possible.
⑥ Pay close attention to water pipe laying.
1. The installation of hot and cold water pipes shall follow the rules of "heating up and cooling down, heating left and cooling right".
2. When the water and electricity are staggered, the leakage of wires and water pipes will not cause short circuit.
3. If you want to change the position of the toilet, the sewage pipe should take the shortest distance, and the smaller the bending angle, the better.
⑦ stare at the circuit wiring.
Wire wiring is prone to construction problems such as cutting corners and wiring, so it must be supervised on site, and it must not be sloppy when it comes to household electricity consumption.
1. The right-angle bend of the conduit is larger, which makes it easier to pull the wire.
2. The wires hidden in the ceiling cannot be exposed separately, and must be sheathed.
3. A pipe can't fit, and the number of wires can only account for 1/3 of the cross-sectional area of the pipe.
4. Strong and weak current lines cannot go through the same pipeline. The distance between the strong and weak tubes should be at least 30CM, which needs to be wrapped with tin foil. Pay attention to minimize the number of joints in the pipeline. If wiring is required, the distribution lines should be well connected, insulated and moisture-proof.
8 stare at the power-on check.
1. Is the wire electrified? When the circuit is just connected, check whether each wire is charged. After installing the socket, check it again. Some careless teachers will forget the grounding wire, which is very dangerous;
2. Some problems are just that the wire connector is not connected properly, but if there is something wrong with the wire itself, it will be troublesome in the future.
Pet-name ruby gaze waterway inhibition test
After the waterway construction is completed, we must pay attention to the suppression test, otherwise the pipeline will leak in the future.
1. After slowly rising to the specified test pressure (8 pressures in general waterways), stop pressurizing and observe whether there is water seepage at the joint.
2. The internal pressure drop within half an hour after voltage stabilization is less than 0.05Mpa, which is qualified.
3. Waterway suppression test can be done several times to continuously test the accurate waterway conditions.
Attending waterproof
1. Toilets and balconies need to be waterproof. According to the standard, the waterproof height of the toilet needs 180cm in wet areas and 30cm in dry areas. Construction standards can only be high, not low.
2. Waterproof materials are generally coated with 2~3 layers, and the method of brushing is adopted. Each layer must be thoroughly dried (not sticky) before the construction can continue.
3. Pay attention to the bottom of the threshold, corners and other places. You can't cut corners for waterproof corners. Some workers and masters are not negotiable.
4. The waterproof layer should be smooth and bright, without cracks and bubbles.
5. After waterproof construction, do a 24-48-hour closed water test! Make sure it doesn't leak to the next door and downstairs, so as to complete the waterproof work.
1 1 staring at the tile paving
1. Look at the flatness of tile paste, and the cutting angle is not in place.
2. Check whether the brick joints are aligned (the wall and floor tiles are aligned), and tap to see if there is an empty drum.
3. Pay attention to the proportion of cement and adhesive used for paving tiles. If the proportion is unreasonable, the problem of falling off will occur.
4. After the tiles in the bathroom and balcony are laid, check the slope.
You need to do another drainage experiment after paving. Once there is water, you need to rework the floor tiles.
Note: Remember to roughen the tiles on the wall! Wall tiles are more stable.
12 pay attention to the leveling of the ground
Before laying the floor, be sure to check whether the ground is flat or not. If the ground is not flat enough, it needs to be leveled.
Leveling method: use a straight plate about 2 meters long and put it on the constructed wall or ground. The standard is that the gap on both sides should not exceed 5 mm
1. The uneven floor will be empty and the floor will creak.
2. After leveling is completed, the owner should go to the site for acceptance in time. If the acceptance standard cannot be reached, let the master rework it in time.
3. Note: There may be repeated charges, which are included in the quotation, but the master asked you to charge it again separately.
13 staring at the floor and carpentry
1. The flatness of the floor installation surface is s2.0mm, and the joint height difference is s0.5mm；;
2. Leave a seam: Because the floor will have an expansion rate, remember to reserve it.
(8- 10mm)；
3. For woodworking furniture, check whether the corners are vertical, whether the doors are deformed, whether the smell of wood is choking, and whether the interlayer between blockboard and fir board is hollow and black.
4. Be sure to pay attention to the smoothness and integrity of the furniture.
14 staring at the paint construction
1. Pay attention to the color difference, especially for dark latex paint. The effect of mixing water and saving paint is poor.
2. The last round must be thoroughly dried before painting the next round.
3. Gypsum putty, with nylon net hanging in the groove. Plastering is not allowed to empty drum! The surface polished with putty is pollution-free.
4. Latex paint does not foam, alkalize, trachoma, drop particles or powder.
5. Workers are required to protect the floor furniture.
6. Stickers with protective films should also be selected so as not to leave glue on the floor furniture.
Stare at the ceiling
1. The ceiling is basically light steel keel and galvanized steel plate;
2. Check the number of main keel, secondary keel and suspender (light steel keel), which is the basis for stabilizing the suspended ceiling;
3. The wooden keel fixed spacing is 600mm；;
4. After the gypsum board surface is inspected for no damage, it is necessary to tick off the joints with glue after the staggered I-shaped installation, and then stick a special anti-crack tape to blow putty, otherwise it is easy to crack;
5. The chandelier cannot be installed on the gypsum board, and it is not recommended to install it on the keel of the ceiling; It is best to add suspenders and keels to make the floor load-bearing;
There are many pipes on the ceiling of the kitchen and bathroom. If gypsum board ceiling is used, it is necessary to reserve an access opening;
16 centralized installation of main materials
1. Fresh air and central air conditioning: it needs to be coordinated with the ceiling, and the ceiling should be reserved with air outlets and maintenance openings. Separate circuits should be reserved for wires, and the thickness of wires should be consulted with manufacturers;
2. Floor heating: the water heating system needs to be tested after installation, and it can only be backfilled after one week without water leakage;
3. Cabinet: Confirm the water and electricity position during installation. The quality of the whole cabinet lies in the edge sealing of hardware and plates. Hardware should pay attention to quality and brand, and need to protect the countertop.
4. Door: When a developer builds a house, the door opening may be irregular. The tile trade union will check whether the door opening is horizontal and vertical in advance and make rectification. The size of the repaired door opening will be customized for the door manufacturer;
