How to Do Plumbing and Electrical in Prefabricated Panel Houses
When doing plumbing and electrical work in prefabricated panel houses, most operations are similar to those for laying pipes in cast-in-place floor slabs. However, special attention should be paid to key points such as the positioning of junction boxes and avoiding steel bars. Here are the specific methods:
Precisely Position Junction Boxes
When conducting plumbing and electrical construction in prefabricated panel houses, determining the positions of junction boxes is of utmost importance. It is necessary to plan the specific positions of each junction box in advance according to the design layout of the house and the usage requirements of subsequent electrical equipment. For example, for the socket and switch junction boxes near the TV wall in the living room, the placement positions of the TV, set-top box, and other equipment, as well as the lengths of the power cords, should be taken into account; for the socket junction boxes on both sides of the bedhead in the bedroom, they should be determined in combination with the size and position of the bed. After determining the positions, use professional measuring tools for precise measurement and marking, and then chisel out the corresponding installation holes in the floor slab. Do not chisel holes randomly, as the structure of prefabricated panels is relatively special. Random chiseling will not only consume a large amount of manpower and time but may also severely damage the structural integrity of the floor slab, affecting the overall safety and stability of the house.
Avoid Steel Bars When Laying Pipes
Laying pipes is a key part of plumbing and electrical construction. In prefabricated panel houses, it is essential to pay extra attention to the positions of steel bars inside the panels when laying pipes. Metal detectors and other tools can be used to detect the specific positions and orientations of the steel bars. After understanding the distribution of the steel bars, proceed with the laying of the pipes. When chiseling grooves or drilling holes, operate carefully to avoid breaking the steel bars. Steel bars are an important part of the load-bearing capacity of prefabricated panels. Once broken, they will seriously affect the load-bearing safety of the panels, reduce the seismic performance and structural strength of the house, and pose a great safety hazard to living. If it is really impossible to avoid the steel bars, communicate with a professional structural engineer to formulate a reasonable solution, such as adopting special connection methods or adding reinforcement measures, to ensure that the load-bearing function of the steel bars is not affected.
