Qualified product will also cause the project to fail
After consideration by the owner Wang, he decided to shop for the home. After buying it for the decoration company, the decoration company's staff told him that in order to ensure the quality of the project, they had been tested by the company's experienced bricklayers before paving and found that the warpage might be problematic. If this situation is followed, even if the construction company's construction personnel are qualified for construction procedures and processes, the final project quality may be unqualified.
Mr. Wang found an agent and the other party came up with a quality inspection report. According to the national regulations, these batches were qualified, including warpage problems within the scope of conformity. Mr. Wang is confused. Qualified products and qualified craftsmanship will result in unqualified projects.
Quality issues - conflicts between the ends
The qualified and professional paving team and the paving process ensure compliance, everything is perfect! Mr. Wang proceeded to prepare for paving... Can't guarantee the quality of the final project inspection? Hearing that the decoration company staff said, Mr. Wang wondered: "qualified products + qualified process / qualified project", and why?
Truth - industry standards have different problems
Since it is in line with national standards, why is it unsatisfactory when it is laid on the ground? Originally, the problem lies in the difference between the "warpage degree" and the "ground project flatness."
According to the size, the degree of warping will also have a corresponding change. Taking 800mm×800mm as an example, the national standard recognizes that the degree of warpage should be between plus and minus 1 mm, while the acceptance criterion for the flatness of ground works is within 0.3 mm. In this way, there will be a phenomenon that the product is qualified and the pavement is not qualified.
The reporter interviewed industry insiders, and Dong Jianjun, general manager of European and American ceramics, said: “The contradiction between the standards does exist. Now many big brands put forward higher standards for brand products in order to improve the quality of their products – corporate standards, effective Avoid such problems."
Qin Ji'an, an engineer at the Shaanxi Provincial Interior Decoration Engineering Quality Supervision and Inspection Station, said: “We generally try to convince the seller to exchange the product.†Li Chi, general manager of Longfa Decoration, said: “In this case, the home improvement company is also very difficult, Try to help customers check the quality of bricks and actively contact sellers for replacement. For products that are not very serious, try to have paving workers spread these bricks to unobtrusive places such as corners, under sofas, and under beds.â€
Experts believe that the acceptance of the paving should be within 2 meters of the brick body after the completion of the error should not be greater than 2mm, brick joints should be neat, there must be empty drums, not loose, with two meters long ruler or by Ruler acceptance. Secondly, you can use a hammer to gently tap on the ground or wall. The emptying rate should not exceed 5%. If there is a requirement for drainage of the floor tiles, the slope should meet the drainage requirements, and the joint with the floor drain should be tight and firm.
