First, be careful not to damage the main structure. Don't casually wear holes in heavy walls, dismantle the walls connecting balconies and doors, and enlarge the size of original doors or windows or build doors and windows. This will cause partial cracks in buildings and severely affect the earthquake resistance, thus shortening the service life of buildings.
Second, be careful not to paving marble. Marble is dozens of times heavier than floor tiles and wooden floors. If the floor is entirely covered with marble, the floor may become overwhelmed. Especially in the second floor or above, the weight of the ground decoration materials must not exceed the specified amount because of the decoration of houses not identified by the housing safety appraisal station.
Third, pay attention to the carpenter's package door and Mason's tiling to match. When wrapping the door, consider whether the following floor (either side of the door on both sides of the door) should be tiled or other cement mortar leveling, because if the door sleeve is nailed before the tile, it is always wrapped to the ground, When cement is used in the future, if the cement and the door cover are stained, it will cause the door cover to be watery and moldy.
Fourth, pay attention to the bathroom must be waterproof. The general practice is, before decorating the toilet room, first block the floor drain, put more than 5 cm of water, to carry out the watering test, if it leaks, you must redo the waterproof; if you do not leak, you should also carefully lay the ground in the construction , Do not damage the waterproof layer and arbitrarily change the water and heating system. When determining the location of a bathroom floor drain, you must first think about it and measure the size. The floor drain is best located on one side of the brick. If it is in the middle of the brick, the floor drain will not be the lowest if the brick is inclined.
5. Care should be taken to avoid holes, holes, ceilings, and installations of art lighting fixtures in concrete circular holes. Especially in the construction, we must pay attention.
Six, pay attention to the wire must use copper wire. If the copper wire is used, due to the poor electrical conductivity of the aluminum wire, the wire is prone to heat, the connector is loosened, or even a fire is caused during use. In addition, during construction, attention should also be paid to the fact that it is not possible to dig trench-embedded wires directly on the wall, and regular bushings should be used to prevent leakage and fire.
Seven, pay attention to the room must not feel depressed. Some people, for the sake of pursuing luxury, put a plate on the four walls, and the ceiling is inlaid with two or three layers of suspended ceilings. This kind of decoration is not advisable. Because the four walls are covered with plates, occupying a larger space will reduce the area of ​​the entire space, the cost is also high, and it is not conducive to fire prevention. A low ceiling will create a sense of depression in the entire room.
The single and double-layer lock air valves mainly use the switches at different times of the upper and lower valves to keep the middle of the equipment in a state where the valve plate is always closed and blocked to prevent air turbulence. If it is under positive pressure delivery, the pneumatic double lock valve can also act as a balancing and booster valve to assist the flow, so that the device can continuously pulsate the feed and at the same time has the function of gas lock to meet the force. The requirements for conveying powdered material. The cement industry is also a lock-in and ash-discharge device for various mills, dryers, silos, silos and closed conveyor systems. The valve is an automatic reset mechanism for the material to open and close automatically under the action of gravity. The hammer has the advantages of stable rotation, energy saving, adjustable discharge capacity, reliable performance of unloading ash and gas lock. There are two kinds of single-door and double-door structure. The single-door double-layer flap valve has good sealing performance; the double door double-layer flap valve has a large amount of ash discharge.
