Many houses that need to be refurbished are mostly old houses that have been older than ten years old. These second-hand houses generally have common problems such as irregular electric boxes and cracking of prefabricated plates. If they are not rebuilt during renovation, they are easy to become hidden dangers and short after renovation. These original problems may reappear during the time. Many decoration companies do not necessarily notice these common problems, and Mr. Anju integrates the common disease prevention and control technology of second-hand houses with exclusive characteristics of B&Q.
No.1 Non-standard distribution box turned into safety specification distribution box
Common problems: In the 80s and 90s, most unregulated distribution boxes can bring safety hazards. The low load of the original household line can not meet the current household electricity demand, which will cause tripping and bring inconvenience to the owner's life.
Prevention: In order to ensure the customer's power demand and safety, set the safety specification distribution box, and have a description of the branch, which is convenient for the future maintenance of the line and avoid line short circuit and tripping problems.
No.2 Use PVC pipe to prevent rot and seepage of cast iron pipe in bathroom
Common problems: the bathroom pit tube is made of cast iron tube. The common problem is that the contact surface between the cast iron nozzle and the toilet drain pipe is rusty and rot, which is easy to cause water seepage.
Prevention: In order to solve hidden dangers and avoid water seepage, the treatment method of PVC drain pipe size head is adopted.
No.3 Gypsum board ceiling to eliminate ceiling cracks
Common problems: old-fashioned public houses, because the prefabricated floor slabs are structural slats, there are often regular cracking in the direction of the joints of prefabricated slabs. The traditional method is difficult to cure the top surface and crack again.
Prevention and control: Take the method of completely eradicating cracking, and adopt the method of gypsum board full ceiling for the decoration of the floor with the required height. The decoration effect is both beautiful and solves the cracking problem.
No.4 new method to solve cracks in door ventilation window
Common problems: old-fashioned public houses generally have ventilation windows. A considerable part of the construction uses the use of blockboard and gypsum board seals. Although the construction is convenient, the shrinkage is strong and cracks are prone to occur.
Prevention: Take the treatment method of sealing the ventilation window, the cement beam should be poured, the bricks should be laid later, the new and old intersections should be sealed with iron wire mesh, then sprinkled with water, and then cement mortar is used to solve the hidden danger of cracks.
No.5 End sink drain pipe is easy to block dysentery
Common problems: the sink itself has a trap, and the cast iron drain has a trap, which is easy to cause the water pipe to block, and the water is slow. Once it is blocked, it is difficult to clear the treatment.
Prevention: Replace the original cast iron pipe with a plastic water pipe without traps, which is convenient for dredging and no potential for corrosion.
No.6 Solving the problem of drain pipe error interface
Common problems: riser cannulated tube connection, not easy to block, easy to seep, difficult to repair.
Prevention: The riser is treated with oblique three-way treatment, and the water is unobstructed, which is convenient for inspection.
