How to calculate the water and electricity for home decoration? The materials are easy to learn and you can become a master.

The water and electricity decoration in the decoration project is complicated, which is a headache for most owners. Everyone knows that water and electricity supplies should be prepared in advance. What should I do with water and electricity in home improvement? Here, Bian Xiao summed up some things to help you answer how to calculate the materials of water and electricity in home decoration, so that you can easily grasp the key points.

First, look at the drawings.

When you get the apartment, the first thing to do is to read the drawings. The layout of the floor plan is the same as that of the map, which is from north to south. Knowing the direction of looking at the house, you can also make basic preparations for home improvement hydropower materials.

Second, measure

Generally speaking, the installation area of water and electricity is calculated according to the indoor construction area. Because the total construction area includes the apportioned area, but the apportioned area has not been constructed. There are projects outside the indoor construction area, which are calculated separately according to outdoor lines, such as outdoor connecting indoor main power lines and garage power lines. Measuring indoor space can help you estimate the amount of water and electricity materials and prepare for your later work.

Three. List of hydropower materials

1, electricity: wire, single-core wire, network cable, cable, video audio cable, network crystal head.

2. Auxiliary materials: wire tube, tee joint, cassette, elbow spring, box-in connector lock, box-in connector lock, direct connector, waterproof insulating tape, waterproof tape, two-in-one broadband TV, one-point TV junction box and circuit breaker.

3. Lamps: kitchen lamp, kitchen work lamp, master bathroom lamp, Nanyang table lamp, north balcony lamp, living room lamp, dining room lamp, master bedroom lamp, fluorescent lamp, main bathroom mirror headlight, downlight, electroluminescence, electroluminescence transformer, passenger bedside lamp and master bedroom bedside lamp.

4. Sockets: sockets (two or three eyes), sockets (two or two eyes), air-conditioning sockets (16A), sockets (three eyes) (10A), single 500Hz video sockets, double 500Hz video sockets, computers/sockets, audio sockets and whiteboards.

5. Switches: single open and double control, double open and double control, single billing control, single billing control, double open and single control and triple billing control.

6. Water pipes: PPR water pipes, washing machine faucets, toilet basin faucets, kitchen basins, basins, toilets, single-knife towel racks, double-knife towel racks, bath towel racks, paper racks, cosmetic mirrors and toilet brushes.

Fourth, the price

1, conduit: PVC hard flame retardant electrical pipe diameter D 16 conduit 3 weak current (TV network cable) passes through the conduit separately. Switch socket bottom box 86 10 yuan/piece; 1 18 type 15 yuan/piece. Add 16 information integration box and 160 yuan/set. Ensure that there is no joint in the pipe, and fill it with gypsum or cement mortar after burying the pipe. Concealed pipe price: 28 yuan/meter. Open pipe price: 18 yuan/m material: 1PVC conduit thickened cold-formed pipe steel wire.

2. No more than 3 high-voltage flame-retardant electrical pipes shall be threaded, and if more than 3 pipes are threaded, 5 yuan shall be added per meter. There is no connector for the wires in the pipe, and the junction box is used. Type 86 switch socket box 10 yuan/piece; 1 18 type 15 yuan/piece, 4 m2 conductor per meter plus 10 yuan. Multiple pipes in the same tank are charged according to multiple hidden lines. Remove the groove, bury the pipe, and fill it with gypsum or cement mortar. Underground pipeline: 35 yuan/m pipeline: 25 yuan/m material: PVC wire thickened cold-bent pipe, electric wire.

3. Waterway reconstruction a.20PP-R water supply pipe (concealed installation): 60 yuan /m b.20PP-R water supply pipe (surface installation): 45 yuan /m C. Launching installation (50PVC pipe): 60 yuan /m PS:PP-R pipe is Wei Xing or Jinde pipe. The launch tube is 1, and each meter contains an equal-diameter reducing sleeve and a 90-degree elbow.

4, excluding valve hardware; 3, 25 water pipes per meter plus 10 yuan 4 less than one meter is calculated as one meter; 4. Punching will be charged separately, for load-bearing wall 40 yuan and non-load-bearing wall 20 yuan.

5.PP-R pipes are all hot water pipes with skin thickness of 2.8.

6. The sewer pipe is calculated as 50; if it is greater than 50, it shall be negotiated separately.

The above is about how to calculate materials for home improvement hydropower, and I hope it will help everyone!
