18-hidden Engineering
It is not easy for programmers xdjm to buy a house. It has been laid by a developer or a second-hand house, and cannot be swallowed up by an installer, a building material dealer, a furniture dealer, or a soft contractor. We need to arm ourselves with knowledge and fight together with js to the end. Let's take a look at the fence home decoration series compiled by Leng Shan.

18.1. waterway reconstruction of concealed works
Http://video.liba.com/detail.php? Id = 95 & Aid = 1 Common Problems in waterway projects are water leakage, rupture, and poor water quality. Pay attention to the following problems: pprpipes for water supply systems and 6 for main water supply systems, branch Pipe with 4 in charge, the construction requires horizontal and vertical, all adopt dark apply. The pipe that is buried in the wall should be a complete pipe and cannot have connectors. Do not slotted the load-bearing wall and the wall with insulation layer. It is easy to crack the surface. The water pipe should go along the top of the wall and can be decorated with a ceiling. When the pipe crosses the floor, a fixed bracket is applied to both sides of the crossing point. Toilet leave a cold pipe outlet, basin, sink, shower or bathtub, leave Cold and Hot Water Two outlets. Test whether each outlet is normal. After installation is complete, the test must be suppressed. The test pressure is 0.6 ~ 0.8mp, ensure no leakage, decompression 2 ~ 3 hours later. The drain pipe must use PVC pipe, 100 pipe for the supervisor and toilet, and 50 pipe for other locations. Close the water outlet and floor drain before construction to avoid blockage. The original launch location should not be changed; otherwise, it would be easy to flushed. The drain pipe should be connected to the exit at the shortest distance. If the pipe is long, the slope will increase accordingly. After the construction, the water test must be performed to check whether the pipeline is smooth. The principle of waterway transformation is to ensure that the main waterway does not move.

18.2. Structure Transformation of concealed engineeringHttp://video.liba.com/detail.php? The structure of the room id = 94 & Aid = 1 is the main frame, which is related to the seismic performance level and safety of use. Structures that cannot be split include: load-bearing walls, half-cut balcony walls, beams and columns, frames embedded in concrete, and steel bars in the walls. The bearing wall carries the basic structure of the housing, and uses bricks and reinforced concrete as the main material. The thickness is above 240mm. The sound of boxing is dull and empty. Demolition and modification are absolutely prohibited. The partition of indoor space is non-heavy wall, the wall is thin, the main material is gypsum board, Cement Sheet, brick body and so on. Click the empty drum to remove the shift. Generally, the attached weight wall is clearly marked on the structure diagram provided by the developer. It can also be determined based on the drawing. Rebuild the circuit. For a second-hand house with a long room age and outdated facilities, re-design the electric meter capacity and change the wires to avoid accidents caused by aging or overload of the wires. Add new houses as needed. The doors and windows of the old house must also be transformed. Wood door and window covers skin deformation, steel door and window covers paint film peeling, rust or cracking, must be removed and redone. Toilet construction is easy to damage the original waterproof layer, should pay attention to protection, if the waterproof layer is damaged, must be repaired or redone. Pay attention to the carrying capacity, the housing is greatly increased, exceeding the carrying capacity, will cause structural damage. Use lightweight building materials whenever possible. The demolition and modification wall must communicate with the property before construction is allowed. Quiet Decoration: http://blog.csdn.net/magus_yang/category/826768.aspx
18.3. Circuit Engineering of concealed worksHttp://video.liba.com/detail.php? Id = 93 & Aid = 1 improper circuit construction, which may easily lead to electric leakage, fire, electrical failure, and other accidents. Be sure to pay attention during construction. Before construction, measure the short circuit of the wire with professional instruments, and then mark the line direction on the wall surface to determine the installation position of the dark box for slotted. Generally, the depth of the cable trough is twice that of the pipe. It must be horizontal, vertical, and consistent in depth. The height of the same dark box should also be consistent. Galvanized pipe with wall thickness on the ground should first be installed with a pipe and then wear a wire. Pipe Bending tools or supporting elbows should be used, and no folding should be performed. Currently, multiple cables are used for wiring, which is beautiful and safe. Wall, top with PVC pipe or trough. The wires in the pipe cannot be connected or twisted. The number of wires in the same pipe cannot exceed 4. After the cables are worn, make sure that the wires are pulled freely in the online tube. The power wire connector should use insulating tape. The electric wires should be configured according to the electric capacity. We recommend that you use 4 mm² electric wires for air conditioners, 2.5 mm² for sockets, and 1.5 mm² for lamps. Do not allow exposed wires in the ceiling, but also do a good job of fire and insect protection. The distance between strong and weak wires should be above 50 cm. If not, electromagnetic waves can be isolated by shielded wires. No connections are allowed between TVs and telephone lines. After completion, we need an electrical circuit diagram. Otherwise, it will be very troublesome for future maintenance. Quiet Decoration: http://blog.csdn.net/magus_yang/category/826768.aspx
18.4. waterproofing of concealed worksHttp://video.liba.com/detail.php? Id = 84 & Aid = 1 in the decoration process, water-related equipment such as pipeline transformation and shower are increased, which may easily lead to problems such as leakage and mildew. Precautions for water treatment: first, we need to perform a 24-hour closed water test. After confirming that there is no leakage, we need to clear the debris from the waterproof construction part and use cement mortar to smooth the area where the potholes are not located, then we flat the entire area. Second, the wall and wall, the wall and the ground, the water outlet and the ground, and all kinds of connections between the pipeline and the ground must be cleaned to prevent virtual leaks. Then, wait until the leveling layer is dry, and make a waterproof layer on the kitchen wall. The construction height should be no less than 30 cm. If it is a lightweight wall, the whole wall must be waterproof. Finally, the bathroom shower wall should be from the ground back to brush no less than 180cm of the waterproof paint, to prevent Bath Splash water wet wall. In addition, it should be noted that the waterproof coating should be fully coated, with no omissions, cracks, bubbles, and shedding. It should be firmly integrated with the grass-roots layer. After the waterproof layer is ready, we recommend that you shut down the water 24 hours a day. After acceptance, you can proceed to the next step.

18.5. Concealed Engineering ProcessHttp://video.liba.com/detail.php? Id = 83 & Aid = 1 concealed engineering refers to the pipeline engineering and Structural Engineering concealed inside the decorative surface. It is particularly important because it involves water and electricity security issues and is difficult to maintain. Water Supply and Drainage, circuits, and waterproofing are the most important aspects of concealed engineering. Water Supply and Drainage is the most common concealed project, including water supply installation and drainage installation. All the water pipes should be smooth. It should be noted that, to change the waterway pipeline, you must say hello to the property, but also ask professionals to design the pipeline direction for construction. In principle, the main waterway is not moved. In circuit engineering, circuit installation requires high material quality and construction technology. Before decoration and wiring, all circuits should be comprehensively designed and planned. pipeline laying strictly follows the operation specifications to avoid electric safety accidents. In waterproof engineering, because of pipeline transformation, the original waterproof layer is easily damaged. If the water treatment is poor, leakage may occur. Therefore, after the waterway transformation is completed, it is best to make the waterproofing immediately. Before wall construction, make sure to perform 24 hours of closed water test. In addition, some projects that cannot be seen from the appearance after completion, such as floors, keel laying of ceilings, wall surface, grass-roots processing of Door and Window covers, are also called concealed projects, only after the concealed projects are completed by water, electricity, and woodworking, And the concealed projects are accepted can the subsequent decoration be carried out.
