How deep should the groove be for hydropower renovation?

Generally, the thickness of building floors is based on 10cm. The upper floors can reach 12-15cm, the basement and the top floor can reach 16-20cm. Those with a thickness less than 10cm are considered unqualified. How can I measure the thickness of my home's floor? The most direct and accurate method is to open the utility well and measure the floor thickness near the vertical line slot. Another method is to measure from the balcony. Generally, balconies are thickened. Measure the total height from the outside, then measure the inside height and then subtract 2-3 centimeters to get the approximate thickness of the floor slab. From this schematic diagram, it is easy to see that there are two types of wire pipes on the ground where we are. One is our own socket, and the other is the lighting on the lower floor. They are buried deep and cannot be reached from above.

This picture is relatively qualified. The position of the wire tube with a thickness of 13cm is clear at a glance. It is impossible to hit the wire tube from above. Generally, the diameter of the gluten and bottom ribs is 12mm for the main ribs and 10mm for the negative ribs. Rebar. Therefore, when decorating yourself, be sure not to damage the shear wall box lintels and the steel structure of the ground ceiling. If everyone cuts it randomly, the consequences will be serious. Back to the topic, the built-in water and electricity pipes are tied to the bottom reinforcement and the number of stacked layers is not allowed to exceed 2. That is to say, the maximum thickness of the pipe is 4cm. According to the picture above, there are 2cm below and 4cm for the pipe. The wire tube is 7cm away from the finished surface.

This is the standard floor thickness, which should be 15cm for high-rise buildings. So what should you pay attention to when decorating your home? It should be noted that bathrooms and kitchens have suspended ceilings in every home. This involves installing suspension bars to the ceiling. The length of the explosive screws is about 4 centimeters, and it is easy to hit the wire pipes. The kitchen will break the ceiling. The socket line in the kitchen on this floor is connected, and the socket line in the bathroom is connected to the socket line on the upper floor. Therefore, it is necessary to re-route the pipes in these two rooms. In fact, we can make partial modifications, that is, move the socket lighting from the top to the bottom of the wall. This way innocent people will not be harmed in the kitchen and bathroom.

I have no idea about the structure of the building, so I let the decoration team follow the inertial construction method, which will lead to the situation as shown in the picture above. The floor slab is not up to standard and is very thin. As a result, it will be damaged by accident. Right worn. If trouble is caused downstairs, it will not only affect the relationship between neighbors, but also feel that it is very unsafe, and the thickness of the floor will be less than 5cm. Will every house live in peace like this? If the groove must be made, it should not exceed 3-3.5cm.

This picture clearly shows the relationship between water, electricity and the floor during the pre-embedding process. The place with the white casing is the bathroom. During the pre-embedded process, the water, electricity and bathroom pipes are on the ground, so later During the decoration, the wiring should be changed to the ceiling (the bathroom floor cannot be routed, and if it is not renovated, it will easily be damaged by the lower ceiling hanger). The kitchen is routed to the ceiling, and the kitchen floor is routed to the sockets and lighting conduits of the lower floor. After this picture is completed, all the beams will be covered, and we will roughly know how thick the floor is.

No matter which construction company it is, the basic process of building water and electricity pre-buried is like this. The lines reach each point in the shortest and most direct way. Some of the pipelines in the corridors of the park are particularly dense, including There are at least 20-30 pipes for strong and weak current management at home, public lighting, fire emergency lighting and other pipes. There are still very few pipes in residents' homes. Here, 20-wire pipes are basically used as strong wire pipes, and 25-wire pipes are used as weak current and air-conditioning wire pipes.

This photo without wire pipe mainly looks at its steel structure. We can roughly estimate its thickness. If the bracket is 10cm, the entire floor will be no less than 13-15cm.

So under what circumstances is slotting necessary?

The decision whether to groove or directly lay pipes on the ground at home depends on the height of the finished floor surface. How do you know what the finished floor surface of your home should be? Generally, the corridor to the corridor has been completed after the building is handed over. We will take the entrance door to be 2cm lower than the corridor to the corridor (from a Feng Shui perspective, the indoor floor should be 2cm below the corridor to attract wealth). , if there is 5 centimeters from the door to the floor, it must be grooved. If it is more than 7 centimeters, just run the pipe directly without grooves (note that no matter where the pipes cross, a bridge bend must be used to ensure that there is only one layer of pipe thickness) In this way, after we lay the floor and lay the bricks, we can reach the standard of 2cm lower than the public part. The thickness of the floor should not exceed 3cm). If we need to lay a 5cm thick ground, our opening margin must be 9cm to eliminate the need for grooves. So are the original embedded pipelines useless? Can it be used? This depends on the communication with the people upstairs and downstairs. If the residents upstairs are re-routing the pipes, we can boldly use the pre-embedded wiring in the ceiling. If the residents downstairs basically have no suspended ceilings except for the kitchen and bathroom, we can boldly use the ground. Buried lines. (The kitchen and bathroom still need to be partially renovated to use the original embedded circuits.) If after communication, we feel that there are too many parts that involve each other, we will re-route the pipes. Whether to make grooves depends on whether the conditions of the finished surface allow it.
