Hydropower installation is part of the house, and its safety and convenience are very much related to the comfort of everybody's housing. Before doing hydropower, the owners can look at the hydropower construction drawings so that you can take a lot of detours. So, how do you look at the hydropower construction drawings ? Next, take a look with Xiao Bian!
How to look at water and electricity construction drawings
First, how to see the waterway construction plan
Look at the water map and you must look at the plan and the system map. Only in this way can you know where the pipeline is turning, where the pipeline is changing, where the water is distributed, and how much the water distribution point is, and when looking at the water supply To see if there are corresponding drainage measures and water facilities, and then consider whether the water supply point and drainage measures and the water facilities are reasonable, if there is a water supply point for the washing machine, the water supply point elevation is generally 1.1 meters above the ground (see the design for details). ).
Look at whether there is a floor drain or a floor drain of a washing machine. Is it a dedicated washing machine floor drain? Are there any traps? These all have a look at whether there is a power outlet for a washing machine, whether the location is reasonable, and whether there is a socket security height or safety measures. Look at the water and maps must have a strong three-dimensional space, to reach the feeling of standing in the room, walking along the pipeline.
Second, how to see the circuit construction plans
Look at the electric map and see first, the height of the socket is installed, the height is up to the safety requirement, the place where the distribution box is installed, the load is, the amount is reasonable, the size of the open space is reasonable, and the outlet protection tube is large Whether the wiring is reasonable or not, and whether the matching of electric wires and electric equipment is reasonable, what is the layout of the line pipe?
In lightning protection grounding, it is to see whether the position of the down conductor “grounding diagram†and “landing protection diagram†are directed to the position of the off-line. If it does not correspond to that, it will be converted in any place. The lightning protection is several levels of lightning protection, and the size of the lightning protection network is Within the scope of the specification, the material, dimensions, material of the galvanized steel bars, and specifications of the guideline, and more importantly, the upper level have no equalization ring against the thunder and lightning, the partial isopotential of the toilet, and the grounding effect of the grounding soil, and the local water level. , Geological conditions. Although many of these designs need to be considered, you need to look at the hydropower diagram. If you look at deepening, you have to look at the rationality and practicality of the design.
Looking at the home-installed water and electricity construction plans, we must also look at the size of the structural beams, whether the size of the pre-embedded casing is reasonable, how much the building elevation is, and whether the height of the room after the installation of the hydropower facilities has any effect. Room size, wall size, seesaw thickness, screed thickness, insulation is internal or external insulation, insulation thickness, internal and external wall decoration layer thickness, when these data are available before accurate pre-embedded, reserved, Production processing.
The meaning of each type of symbol
