Pay attention to 6 traps in hydropower decoration

  • Detail

Attention should be paid to the six "traps" of water and electricity decoration

many decoration problems and hidden dangers cannot be seen with the naked eye, or can't be found immediately. They are like a timed 'problem bomb', which 'attack' and 'detonate' from time to time in people's daily life, which is laborious, laborious, time-consuming, and even worth money. In fact, as long as we master the basic norms of construction and are familiar with the doorways, every layman of decoration can have a pair of golden eyes to supervise the construction directly to the key problem, so as to reject bad home decoration

here is an introduction to the construction technology that is easy to occur in the early stage of decoration, such as inadequate construction technology, violations and so on. It seems to be as small as sand, but in fact, there are endless disasters

problem 1: the workers did not properly handle the live wire, ground wire and zero wire. On the surface, one yellow line and two blue lines make people don't know the ownership of each line, which has great potential safety hazards

the supervisor explained that it did not meet the acceptance standards. According to the regulations, the live wire is red, the ground wire is decor, and the zero wire is blue. If the initial construction is not differentiated, it will bring trouble and problems to future work, for example, when others change sockets

question 2: the exposed wire ends are illegal, and the exposed wires are dangerous. In addition, the electric pipe is too close to the water pipe

the supervisor explained that the decoration management regulations stipulate that exposed wire ends must be wrapped with insulating tape to prevent workers from being electrocuted during construction. In addition, a distance of at least 20 cm should be kept between the electric conduit and the water pipe

problem 3: there is no junction box when branching, and the PVC conduit is not fixed

the supervisor explained that in the circuit transformation in the ceiling, the junction box must be added to the junction box; Secondly, PVC conduits should be fixed at a point every 50 cm, otherwise the wires are easy to swing disorderly, which will increase the difficulty of installing lamps in the future. In addition, hoses are required between the junction box and the lamps corresponding to the ceiling

problem 4: the PPR tube is not fixed to the top surface and is too close to the bulb. In addition, there is water seepage around the PVC sewer pipe

the supervisor explained that the PPR pipe must be fixed on the top surface. According to the regulations, it should be fixed at a point every 50 cm. Secondly, if it is too close to the bulb, the tube is in danger of being baked. In addition, before construction, it should be ensured that the closed water acceptance of the toilet of the residents upstairs is qualified

question 5: in the circuit transformation, workers slotted horizontally on the wall in order to bury pipes

the supervisor explained that according to the management measures for building decoration, during the interior decoration process, it is not allowed to slot horizontally on the bearing wall, let alone cut off the reinforcement in the bearing wall, because this will damage the main structure of the wall and shorten the service life of the building

question 6: the worker accidentally leaked the water pipe

the supervisor explained: before construction, it is necessary to check whether there are signs on the ground such as' no drilling in the line 'to avoid breaking the underground pipelines. In addition, pay attention to keep water in the pipe during construction, and once it is broken, problems can be found in time; If the main valve is opened at the time of completion, the pipeline is found to be leaking, resulting in greater losses
