A removal: removal of doors and windows, removal of floor tiles and floor, removal of non-load-bearing walls, and removal of water heaters. The key to the dismantling of doors and windows is safety. The demolition of the waterway must be closed. The demolition of the circuit should pay attention to insulation.
Second hidden construction: waterproof construction, waterway transformation, circuit transformation.
Three basic project construction: old house wall surface base treatment, house type renovation, door and window replacement, balcony insulation and so on.
Four regular renovations: As long as the demolition and concealment works are done, it is easy to make regular decoration.
1, circuit transformation
The transformation of the new house circuit is to increase the socket and lamp base in the original foundation, and the circuit transformation of the second-hand house generally abolishes the original line, because the original line is already aging, and the second is unable to meet the electricity demand of the modern family. Leakage protection test is not in place.
Redesigning the circuit not only meets the user's current power needs, but also considers the possibility of future. The newly designed circuit generally has 4 to 6 sets of circuits, in accordance with the order should be lighting a circuit (2.5 mm plastic copper wire) ordinary bedroom socket a circuit (2.5 mm plastic copper wire) kitchen bathroom socket a circuit (4.0 mm plastic copper wire) One circuit in the living room air conditioner (4.0mm plastic copper wire) One main switch in front of the bedroom air conditioner (4.0mm plastic copper wire). In order to prevent electric shock and overload due to leakage and improper use, indoor electric power must be installed. An air switch shall be installed on the wiring box lighting and the air-conditioning circuit respectively, and a leakage protector must be installed in front of all outlet circuits.
Weak systems (including telephone lines, network cables, TV antennas, etc.) Most of the old houses are on the clear line, and the new homes in the second renovation process are more beautiful and conditional. It is recommended that they be changed to dark lines. Well, let the weak currents be at least 30 cm away from the strong lines.
2. Waterway reconstruction
The waterway is divided into water supply and drainage (also known as upper and lower water), while the water supply is also divided into hot and cold water, and hot and cold water reform is the focus of the renovation of the bathroom. The waterways of the old houses are mostly galvanized pipes that are prone to rust, fouling, and bright pipes. The renovation of a new house can be partially rebuilt and replaced. The old house is best replaced from the main pipe diverter valve. Since the bathroom of the old house is not very large, even the total replacement of the water pipe will not increase much. On the premise of ensuring the safety of water supply, the pipeline should be shortened as much as possible, but it must also be convenient for maintenance and aesthetics.
The bathroom of the old house is small. In order to expand the space, it is very necessary for the waterway to open and remove the dark pipe. However, the water pipe buried in the wall cannot have a joint, and it is better to have a complete pipe. According to our long-term experience in repairing and repairing old houses, nine out of ten leaks in water pipes are problems with joints. It is best to use pressure equipment to perform the pressure test before the water tube is installed and sealed. The general construction team replaced the pressure test with whether the water pipes leaked under normal conditions.
The original sewage pipes and floor drains of the old houses could not meet the needs of modern people. Only by adding pipes to move the water outlets, before the new pipelines and old pipelines were docked, it was necessary to check whether the old pipelines were unblocked. At this time, clean-up would avoid many future trouble. The original stool drainage outlet of old houses, many modern new toilets due to the pit distance, drainage methods and other issues, can not be installed directly to use, to move the location of the sewage outlet is not a very easy thing. We often use the toilet shifter to meet the above problems. Many people think that the toilet shifter will affect the flushing, but we believe that the toilet shifter will not affect the flushing as long as it is installed properly.
3, the old house waterproof precautions
a After removing the floor tile, use cement mortar to level the floor, and then do waterproof construction to avoid leakage due to uneven thickness.
b When chiseling the bathroom wall tiles, the walls will vibrate due to the beat. At this time, the joints on the wall and the ground and other corners should be carefully applied.
c When installing the upper and lower water pipes, it is unavoidable that the upper and lower water pipes erected by the toilet will be loosened. Therefore, the upper and lower water pipes shall be used to protect the roots of the pipes first, and then the floor shall be waterproofed to form a composite waterproof layer.
d After the bathroom wall tiles are cut down, check whether there are empty drums, sand, cracks, etc. on the walls. If yes, repair it first and then brush and waterproof it.
e. Make more waterproof once in the old house's yin and yang corners, floor drains, and pipes. Accounts are carefully checked and accounted for. , design all free), offers a lot, do not miss.
