note 1: don't dismantle the load-bearing wall indiscriminately; Dismantling the load-bearing wall privately not only has serious hidden dangers, but also violates the relevant regulations of the state. The load-bearing wall is the main body of the house. Once there is a problem, it will not only suffer economic losses, but also be subject to legal sanctions. Pay attention to the walls that can be dismantled and rebuilt, which are detachable and which are not. So consult the property before demolition, because the property will have some structural drawings of the house. In the absence of drawings, there are doors and exterior walls. Try not to tear them down. Moreover, taking a ruler to measure the thickness of the wall is definitely a load-bearing wall; These walls in the bedroom must be load-bearing walls. They can't be removed.
note 2: hydropower transformation; Generally, the original waterway pipelines have many unreasonable layouts or are corroded, so the waterway is thoroughly inspected. If the original pipeline is a galvanized pipe that has been eliminated, it must be completely replaced with copper pipe, aluminum-plastic composite pipe or PP-R pipe during construction. Recently, there are many PP-R pipes that have been used, which must be replaced.
note 3: circuit modification; The decoration of second-hand houses is generally characterized by simple circuit distribution, aging wires and illegal wiring, which can no longer meet the electricity demand of modern families. Therefore, it is necessary to completely transform and rewire during the decoration. Since aluminum wires were used in the past, we need to replace them with copper wires we are using now, and PVC insulated protective tubes should be used. For the lines with high-power electrical appliances such as air conditioners, it is necessary to run the lines separately. Simply put, it is to start over. As for the socket problem, we must add more sockets, because the sockets of second-hand houses can't reach the number of electrical appliances now, so this must be changed in decoration. < P > Note 4: Tile floor renovation; When smashing wall bricks and floor bricks, avoid debris blocking the sewer; Only solid wood flooring, solid wood composite flooring and bamboo flooring with a surface thickness of 4 mm can be renovated. In addition, local renovation will also cause differences between the old and the new floors, so consumers can't blindly renovate the floors
Note 5: Three-sided decoration; The renovation of the wall, floor and ceiling of the second-hand house is the most easily overlooked. The original decoration of the old house generally uses hydrophilic gypsum putty, and it needs to be completely eradicated before using water-resistant putty. < P > Note 6: The closed water test is the most important and essential.
