by Photo source: we can see some non load-bearing components of TV Zhubang Hongsheng quality model secondary structure in frame, shear wall and frame shear wall works, such as masonry, structural column, lintel and other parts that need to be completed before decoration are called secondary structure.
The reason why it is called secondary structure is that its process is carried out after the construction of load-bearing components.
Compared with the load-bearing structure, the secondary structure is a non load-bearing structure and maintenance structure, such as structural column ring beam, water stop reverse beam, parapet, coping, infilled wall, partition wall, etc.
Photo source: I see that the secondary structure of TV Zhubang Hongsheng quality model is also the same as the structure, including the retention of test blocks and the application for inspection of inspection lots.
It should be flexibly used and mastered in actual operation.
If the quantities are small, several layers can be combined into one inspection lot.
The data are as follows: inspection lot of reinforcement raw materials, connection, processing, installation and concealment, formwork installation, concrete pouring and cast-in-situ structure source: it can be seen that the masonry inspection lot of TV Zhubang Hongsheng quality sample infilled wall masonry infilled wall can be made in layers, and the inspection lot of one layer can be made after one layer is completed.
If the area of one layer is too large, it can also be subdivided according to the axis; If the area of a single layer is small, it can be applied for inspection once for two or more layers, which shall be determined according to the actual situation of the construction site.
01 application form for inspection 02 quality acceptance record of inspection lot of infilled wall masonry works 03 acceptance record of concealed masonry works..
