At present, many of the problems after home decoration stay in the hidden project. Moreover, because construction problems of concealed projects directly affect the quality of life of the owners, it can be said that hidden projects play a crucial role in the overall construction of home renovation. For example, during construction, the conductors are not covered with insulating tubes. After the owner has checked in, for some reason, the conductors are broken and the conductors are short-circuited, which directly affects the use. However, these problems may not be revealed during project acceptance. Therefore, it is very necessary to emphasize the importance of concealed project construction. Here, we will collectively define the construction of the waterproofing project, the distribution project, the water supply and drainage project, and the wood keel installation in the construction of the home decoration as a hidden construction project.
Waterproof construction proposal 1, cleaning preparation: First of all, should be prepared for waterproof construction parts, such as wall and floor surface debris clean up, shovel off the loose part, and then use the cement mortar to grind uneven rough place , And then make the whole big face once to level.
2. After the cement screed is dry, it should be constructed in strict accordance with the construction requirements of the waterproof material (see construction instructions).
3, in the kitchen bathroom wall waterproof layer, waterproof layer construction height should not be less than 30 cm. If the wall itself is a lightweight wall, waterproof the entire wall must be treated.
4, the intersection of the wall and the wall and the intersection of the wall and the ground to do the root treatment, with a corner wipe or finger sweep, clear, should strictly prevent the emergence of virtual leakage.
5. The root of the junction between the outlet and the ground shall be treated with clear roots. The junctions between the various types of through pipes and the ground shall be treated according to the above method.
Special Note: Since most of the waterproof layer leaks are caused by corners, the possibility of leakage is very small as long as the edges are treated properly.
Water and water project construction proposal (specifically refers to iron pipe)
1. The galvanized iron pipe must be used for drinking water pipes to prevent secondary pollution of drinking water.
2, hot water pipe sealing must use hemp, cold water pipe can use PTFE.
3, if the connection distance is greater than 1 meter, in principle, should prohibit the use of hose.
4. It is forbidden to bend the utility hose when using the utility hose to prevent the hose from being damaged and broken.
5. When the iron pipe is connected at 90 degrees, the length of the pipe threading must not exceed the diameter of the pipe.
6. The installed water pipes must be fixed (especially hot water pipes).
Special Note: When the plumber uses the threader plate thread on the water pipe, if the thread length is too long, it may cause the water flow section to be too small when connecting at 90 degrees, resulting in the tap water being too small and affecting the future use.
Distribution engineering construction suggestions 1. According to the requirements of the project distribution of the circuit, we must first make the line marking on the wall and the ground, determine the position of the future cassette installation, and prepare the slot.
2, in the wall in accordance with pre-made wire troughs to mark, open a good depth of the appropriate wire slot (according to the diameter of the line pipe and the number of line pipe decision), and open the cassette buried groove. Wire troughs must be horizontal and vertical, consistent in depth; the position of the cassette requires the same height of the cassette.
3, laying line tube. Here we should pay attention to: the wall laying of the line pipe to use rigid PVC pipe; the ground laying of the line pipe to use water gas iron pipe; pipe and pipe connection between the use of pipe joints; 90 degree corner to use 90 degree elbow Must take fixed measures on the line tube; TV antenna coaxial cable and telephone line to be worn alone, and the adjacent line tube to maintain a distance of not less than 30 centimeters; pipe diameter to ensure that after pulling threading freely.
4, fixed cassette, and adjust the position of the cassette.
5, the wire into the line tube, pay attention to the power cord to minimize the connector; TV coaxial cable and telephone line is strictly prohibited connector; power lead connector needs insulation tape and waterproof tape for double insulation.
Special Note: In the home renovation, there have been the phenomenon that the electrician walked the line very well and could be inadvertently damaged by other people. Therefore, in order to ensure that the above situation does not occur, it is better to mark the position of the trace.
Floor wood keel construction proposal Many companies do not regard the construction of wooden keel as a hidden project. The reason why this arrangement is arranged by the author is to unify the invisible engineering projects after completion.
1. The specifications of the wooden keel must not be less than 2.5 x 3.5 cm in principle. If the conditions permit, wooden keels of a size as large as possible should be used.
2. The spacing of wooden keel should be determined according to the length of the floor, but the supporting keel below each floor should not be less than two, otherwise it will directly affect the floor force and shorten the service life of the floor.
3, the fixation of wood keel to use both nailing and adhesive two methods, nails should be 45 degrees from the two sides into the wooden keel, as limited by the construction conditions, must be inserted from top to bottom, you must nail The cap is not in the keel.
4. The joints of each row of wooden keel must be staggered. It is strictly forbidden to arrange wooden keel joints in a line, which will affect the overall force of the keel. Due to the problem of the ground, there will be a certain gap between the wooden keel and the ground, and the gap between the wooden keel and the ground must be adjusted with a wooden wedge, and it should be plugged. The use of a small wood plug pad is strictly prohibited.
5. If the project cost permits, you can also use the following methods to improve the installation level: 1? Leveling the entire ground with cement mortar mainly depends on whether the time of the project can be used for this purpose. 2? The space between the keels is filled with ceramsite or slag, on the one hand, the space between the keels can be filled, and in addition moisture can be absorbed; 3? Before installing the keel, brush the waterproof coating on the floor; 4? Before installing the keel, the floor was covered with plastic film, which was similar to the third point, but it was rarely used; 5? The top of the keel is equipped with a layer of high quality blockboard (commonly known as the big core board) as the wool floor, which can play a role in overall connection and even force. However, if the wood floor is made directly from wood, the cost will be higher.
Special note: The looseness of the wood keel after installation is not allowed. There should not be a difference of more than 0.5 mm between adjacent keels. If such phenomena occur, they should be dealt with promptly.
