In the construction process of the construction project, although the bathroom area is not large, the construction of the bathroom involves many processes such as civil construction, installation and decoration. It is easy to have common quality problems during the process handover and cross construction, and it is also the focus of renovation and construction. difficulty. Xiaobian will give you some hidden dangers and first aid methods for bathroom partitions.
The toilet construction should be controlled as a key quality control point during the construction process. Attention should be paid to the following tasks: serious secondary design and technical disclosure; special personnel responsible for coordination and supervision; reasonable arrangement of construction procedures; strict implementation of process handover acceptance system.
First, the ground leakage
Although the leakage prevention of the bathroom floor is the most basic requirement of the project quality, the leakage of the bathroom floor is quite common, and most of the leakage is not due to the waterproof itself (the waterproof layer needs to be stored in the water test, and problems can be redone.) In most cases, it is caused by insufficient coordination between the civil engineering professional and the installation professional. Therefore, all processes that are likely to cause ground leakage should be strengthened and strictly required.
Second, the surface area of ​​the brick
The cause of the area water is mainly caused by the slope (generally 0.5%) and the unreasonable trend. When determining the slope, the height difference should be determined according to the longer side of the wall root to the ground drain, and all the wall roots should maintain the same elevation. If the height difference between the ground structure of the bathroom structure and the corridor structure cannot meet the requirements for finding the slope, the following measures should be taken:
1. Due to structural construction errors, the steel protective layer is too high, and it can be properly chiseled at the local level, but it must be ensured that the thickness of the protective layer of the steel bar meets the design requirements.
2, due to structural construction errors, the steel bar is too high to be chiseled, only the doorway plus the door stone method to meet the slope requirements. However, the quality inspection department generally does not allow this, and can communicate with the quality inspection department in advance, and find ways to make the door stone more reasonable and beautiful, because the protective layer of the steel bar involves the safety of the building.
Third, the floor brick hollow
The reason for the empty floor tiles is that the grounding operation is not standardized, mainly because the cross-operating personnel are stepping on the mortar when the mortar has not solidified. The only way to avoid it is to close the glue after the paste is finished and the dispenser is maintained.
Fourth, brick bricks
The main reason for the sulphation of floor tiles is due to the performance of the cement, even if the test report shows that it is qualified, it is difficult to avoid. From the perspective of construction control, the seams must be filled when caulking. During the construction process, the caulking process is easily neglected, and the caulking operation requirements are rarely stated in the technical disclosure. The workers generally only use the cement plaster to smooth the surface of the seam, forming a water storage cavity in the brick joint, and the water will The alkali metal oxide in the cement dissolves and reacts with CO2 in the air to form a white compound. The caulking method of the suction pipe specification is the kettle potting, that is, the cement mortar is mixed in the kettle, the spout is poured along the 1~2mm brick joint, and after the filling, the sediment is 1-2 hours, and the perfusion is repeated. Until the sputum cement mortar has not solidified, it is repeatedly compacted with fine wire.
Five, the wall of the brick roots of the efflorescence
Wall tile caulking can not be used for kettle caulking. The reason for the formation of efflorescence at the root is multi-faceted. The following measures can be taken to avoid:
1. The wall brick at the root of the wall should be pressed on the floor tile. The brick joint at the corner of the corner is difficult to fill. The acetone waterproof paste is used to match the color of the tile.
2. The height of the waterproof layer should be no more than 300mm above the highest finish of the platform.
3. The lightweight partition wall should be used as a concrete waterstop in the wall root as required. Some of the general packaging units hand over the light partition wall project to the supplier for construction, and the supplier does not have the woodworking, bricklayer, industrial hose workers and other types of work, and can not do concrete waterstops. The best way is to construct the concrete waterstop for the lightweight partition wall by the masonry team.
Sixth, wall bricks and floor tiles are not matched
1. Try to use the toilet with the shape rule; the cutting of the flushing pipe part is more troublesome, and the effect of the casing after the cutting is generally poor. To ensure the beauty, a stainless steel cover ring can be used for decoration.
2. The sleeve cutting at the triangular tube bracket of the riser is difficult, and the stainless steel cover plate can also be used for decoration.
7. The layout of wall tiles and floor tiles is not beautiful.
The layout of wall tiles and floor tiles should be considered comprehensively. It can be referred to the practice of some fine engineering projects. Before the final draft is formed, it must be jointly determined by the project department and the company's technical personnel. Common technical requirements are no longer exhaustive. The following two methods are for reference.
1. The floor tiles can be equipped with a coordinated ribbon to match the brick modulus according to the layout of the toilet, urinal and washroom.
2. Wall bricks can increase the modulus of the bricks at the doors and windows of the coordinated ribbons at the height of the window sill.
8. The large set of cuts at the ceiling pipe does not match.
The same method is adopted for wall brick, floor tile pipe sleeve and vacuum pipe cutting, and the stainless steel cover ring decoration is added.
Nine, the gap between the ceiling and the wall is too large
Acetone sealant caulking can be used to match the color of the ceiling finish. The tape is used to match the caulking, and the post-capping sealing seam is small (<5mm) and a straight line is formed.
Ten, the upper surface of the toilet is not horizontal
The reason why the upper surface of the toilet is not horizontal is mainly that the installation is not firm, and the positioning is moved when the backfill or the tile is pasted. When installing, the bricklayer can first build a red brick base on both sides of the toilet, and then the installer adjusts the positioning and firmly adheres with the cement slurry.
