Ceiling embedded smoke pipe
[Unreasonable flue setting]
Crime 1: suction Weakness
Due to the unreasonable setting of the flue, the size of the flue is different, the smoke is not strong enough, or the flue layout is too long and there are many turns, resulting in blocked suction and insufficient wind pressure I can’t smoke all the fumes, so within a few minutes in the kitchen, it becomes full of smoke, which seriously affects the cooking mood.
Crime 2: Excessive noise
The exhaust pipe is too long or has a “dead bend” phenomenon. The more the smoke exhaust pipe of the range hood is bent, the greater the pressure loss, resulting in less suction, poor smoke exhaust, and the hood and the smoke pipe will make a “rumbling” noise. The exhaust pipe should be shortened as much as possible, and the turning radius should be as large as possible to ensure smooth air outlet, increase the exhaust effect, and naturally reduce the noise.
Crime 3: Oil dripping from the ceiling of the hood
The flue setting is unreasonable, the smoke is blocked, and the suction of the hood is not enough, resulting in insufficient air pressure. Inexhaustible fumes, or if the hood flue and turbine have not been disassembled and cleaned for a long time, it is easy to cause the hood to drip oil and leak; what’s more, because the smoke pipe is not well sealed, there is a gap between the smoke pipe and the hood, and the fumes cannot Completely drained, oil seeps at the interface for a long time, causing oil leakage from the ceiling.
[There are many unreasonable flue conditions]
1. Inverted smoke smell: unreasonable flue setting, or no anti-smoking treasure , causing the smell of smoke from other kitchens to be reversed with the public flue.
2. Damage to health: The unreasonable setting of the smoke pipe will lead to the inability to discharge the fumes and fill the kitchen. Living in such an environment for a long time will affect human health.
3. Strong shaking: There is no “public flue check valve” (smoke-proof treasure) installed in the flue, and the decoration workers “poke” the flue into the flue at will, so that the mouth of the flue is in direct contact with the flue. On the inner wall, all the exhaust smoke bounces back, causing the fuselage to shake violently; the exhaust duct is not smooth (squeezed or bent too much), resulting in poor air circulation, causing the motor to be in a similar overload state, with abnormal noise and vibration.
[Correct pipe layout]
1. Enlarge the public flue
Put the public The diameter of the flue is enlarged to: 180(mm)×190(mm). Ordinary public flue openings with a diameter of less than 15 cm will affect the smoking effect of the hood and bring noise and vibration.
2. Replace the anti-smoking treasure that does not meet the standard of the hood
The diameter of the ordinary cigarette pipe is 18cm, and the size of the built-in anti-smoking treasure is too small (diameter 10~15cm), the air volume of the hood will be reduced by 30%~70% after connecting with the smoke pipe. The diameter of Siemens smoke-proof treasure is 18cm, which is perfectly matched with the smoke pipe, and the air volume is almost no loss. It can also effectively prevent the backflow of oil smoke and odor.
3. Straighten the chimneys
Arrange the chimneys reasonably to find the best path between the chimney and the public chimney. Stretch the cigarette pipe, the experimental data shows that: the cigarette pipe is bent, wound, and compressed, and the air volume is reduced by at least 10% each time.
4. Ceiling openings
The air outlet is to the left, so the ceiling openings need to be at the location where the hood is installed The centerline is 5 cm to the left.
5. Maintenance and overhaul of the flue
If your home has a gypsum ceiling or a wooden ceiling, be sure to reserve a 300 ( mm)×300(mm) inspection port, which is convenient for the maintenance and repair of the flue in the later stage.
Tips for renovating water and electricity slots
It is not easy to find the water path, because the water flows down, and the leaking place does not necessarily flow out first , only when the water leaks to the downstairs or the water floods Jinshan, will the water leak be found, but because it is a hidden pipe, it is impossible to find the leaking place immediately, so the loss will be quite large; if the ceiling is taken, the kitchen and bathroom can use aluminum gussets to suspend the ceiling To cover it, we walk along the corners when passing through the wall and the entrance. It can be wrapped with plaster wire without affecting the appearance.
How to carry out water and electricity slotting in home decoration
1. Confirm the direction of water pipes and locate water equipment:
The customer determines the direction of the water pipes according to the decoration design drawings and the house type structure. The direction of the water pipes can be divided into ceiling arrangement, wall groove arrangement, ground arrangement and open pipe installation. Which method to choose should be negotiated with the decoration pair.
Generally speaking, the principle of water pipe grooving is “go to the top without going to the ground, go up and down without going horizontal”, because there are many buried pipes and wires underground, in case the original underground is damaged. The pipeline will be very troublesome, and if it goes to the ground, in the later decoration process, in case the electric drill damages the water pipe, it will affect the safety.
It is not easy to find the waterway, because the water flows to the low place, and the leaking place does not necessarily flow out first. It is a hidden pipe, and the leaking place cannot be found immediately, so the loss will be quite large; if it goes to the top, the kitchen and bathroom can be covered with an aluminum gusset ceiling. On the wire package, it does not affect the appearance.
When the water pipe is led from the top to the bathroom, when you encounter the place where you need water, open a vertical groove and go down, and reserve the shower, basin, washing machine and other water outlets at a suitable height. The advantage of this is that after the decoration is completed, you can judge the direction of the water pipe according to the position of the water outlet. All the water pipes are vertically upward at the water outlet, so as to prevent the water pipes from being damaged for any reason, and once water leakage occurs, it is convenient for maintenance.
2. Attention should be paid to waterway design:
1) Waterway design should first consider all water-related equipment, such as water purifiers, Water heaters, kitchen treasures, toilets and wash basins, etc., their locations, installation methods and whether they need hot water
2) Think ahead of time whether to use gas or electric water heaters to avoid temporary replacement of water heater types, resulting in duplication of water circuits Retrofit.
3) In addition to leaving the washbasin, toilet, washing machine and other water outlets in the bathroom, it is best to take one out, and it is very convenient to collect water and mop the floor later; it depends on the owner’s preference. .
4) After the location of the washing machine is determined, the drainage pipe of the washing machine can be considered to be inside the wall, which is beautiful and convenient.
3. Slotting process specification:
1) After communication with the construction personnel, the water modification will start construction. First draw a line with an ink line to outline the route that needs to be taken (you can see from the route map that it is horizontal and vertical. If you have different opinions or changes at this time, you can also discuss with the worker). These preparatory work, about an hour or so.
2) After the wire is played, it is to open the dark groove. Use the special tool cutting machine to cut the groove surface according to the line, and then use the electric hammer to open the groove. In addition, it should be reminded that some communities are load-bearing wall steel bars. More and thicker, you can’t cut the steel bars (affecting the quality of the house), you can only open shallow (the cement needs to be thickened when tiling) or open the pipes, or go around other walls.
4. Slotting construction size requirements:
There must be a space between the hot and cold water pipes. Because the hot water is heated by the water heater, the heat is also lost during the circulation process. If the hot and cold water pipes are close together, the cold water is also circulating, and the heat loss of the hot water pipes is also very great.
Requirements for the size of the hole through the wall: If the diameter of the wall hole for a single water pipe is 6cm, if the diameter of the wall hole for two water pipes is 10cm, or two wall holes with a diameter of 6cm are used to separate them.
11 construction specifications for water and electricity slotting
1. Before opening the slot on the wall and ground, use the ink cartridge to snap the wire to facilitate positioning. The buried pipeline groove on the wall must be horizontal, straight, and straight, and must not be bent. In special cases, it must be approved by the supervisor. The groove on the wall should be kept >33mm, and the pipe surface and the wall should be left with a powder ash layer of about 15mm to prevent the wall from cracking.
2. It is not allowed to destroy or change public electrical facilities without permission, such as lightning protection grounding, protective grounding, etc.
3. When the power line pipe is buried in the dark, it should be considered to maintain a distance of more than 500mm from the weak current pipeline, and the parallel distance between the electric line pipe and the hot water pipe and the gas pipe should not be less than 300mm.
Reduce turns as much as possible, and avoid the installation positions of wall mirrors, shelves, furniture, etc. to prevent damage by electric hammers and nails.
5. If there are no special requirements, in the same suite, the switch should be about 1200-1500mm from the ground, 150-200mm away from the door, the socket should be about 300mm from the ground, and the socket switches should be on the same horizontal line. The difference is less than 8mm, the height difference is less than 1mm when installed side by side, and it is not blocked by sliding doors, furniture and other objects.
6. There should be no shortage of various strong and weak electrical sockets. There should be power sockets and a telephone socket on both sides of the bed, and more than three should be set near the computer desk and on the background wall of the TV cabinet in the living room. and set up corresponding TV, telephone, multimedia, broadband network and other sockets.
7. The laying method and requirements of weak current lines such as audio, television, telephone, multimedia, broadband network, etc. are the same as the laying method of power lines. Lines are not allowed to share a set of pipes.
8. All in-wall wires are buried with PVC flame retardant pipes with a size of 16 or more. The wires occupy the space of less than 40% of the pipe diameter, and special interface parts are used to connect with the bottom of the box.
9. When using the original conduit, a reasonable turning radius should be made for the power conduit to pass through the ground. Special attention must be paid to the use of casing to connect tightly under the ground. No joints are allowed under the ground. Before it is closed, the PVC casing must be protected, and no cracking damage is allowed; when laying floor tiles, the PVC casing should be completely covered with cement mortar.
10. The wires in the ceiling and the lamp head wires should be protected by PVC metal corrugated pipes, and cannot be replaced by other materials. When it is difficult to slot the ceiling, the wires can be directly buried after passing through the imitation wax pipe, but the passage must be reserved. box for wire replacement. The expansion pipeline laid in the ceiling should be fixed with pipe clamps, and the distance from the ceiling surface must be greater than 50mm.
11. The conduit entry groove should be fixed with cement nails, and the steel wire should be wound and connected, swept with cement mortar, straight and tidy, and paint should be used to mark the direction of the conduit after concealment.
How to prevent the perforation of the ceiling from destroying the line pipe
1. After the reinforcement of the floor slab and the electrical piping are completed, and before the concrete is poured, the line pipe should be placed in the formwork along the direction of the line pipe. In the steel grid on the top, use a brush with a width of 50mm dipped in red or black paint to draw a broken line. Pay attention that the paint should not contaminate the steel bar, and the width of the line is about 10mm.
2. After the concrete is poured and the formwork is removed, the broken line drawn on the formwork will be clearly printed on the bottom of the cast-in-place concrete floor. This line is to guide the direction and location of the distribution line. part marking line.
3. When the project enters the decoration stage, the electrical technician in charge must make on-site disclosure to the civil engineering decoration personnel, explain the purpose of this line to the decoration personnel clearly, and require it to be within 10cm on both sides of the marking line. Drilling is prohibited.
4. The line drawing method can not only avoid the occurrence of various pre-buried electrical conduits in the cast-in-place concrete slab due to drilling, but also use the threading method when the pipeline is not smooth. Use wire to measure out the faulty part.
