Sealant is a tiny but indispensable building material, but do you really understand its usage estimation?
How to estimate the amount of structural sealant for curtain wall?
In the first step, we preset the total area of curtain wall, plate size, glue joint size, volume of structural sealant and utilization rate of structural sealant respectively:
Total area of curtain wall: m (M2)
Plate size (side length × side length): a × B (cm × cm)
Glue joint size (width × thickness): a × B (cm × cm)
Volume of structural sealant: V (ML)
Utilization rate of structural sealant: μ (%)
The amount of structural sealant used for a single plate (ML) is: 2 (a + b) × a × B
The second step, because of the difference in the amount of sealant applied to the full hidden frame glass and the half hidden frame glass, this course is divided into two calculation directions: the estimation of the amount of sealant applied to the full hidden frame structure and the estimation of the amount of sealant applied to the half hidden frame structure.
Consumption estimation
? structural sealant shall be injected on all four sides of the full hidden frame glass, so the amount of structural sealant shall take into account the amount of four sides.
Estimation of the amount of sealant used in full hidden frame glass structure
? only two sides of the half hidden frame glass are injected with structural sealant, so the estimation of the amount of structural sealant is slightly different from that of the full hidden frame.
Estimation of the amount of sealant for semi hidden frame glass structure
In curtain wall projects, structural glue is used for hidden or semi hidden frame glass curtain walls and open fans, and the number and size of glass plates are different, so it is difficult to calculate accurately. At the same time, the plate size has installation deviation, the utilization ratio of glue used by different workers is different, and the glue injection size and design size are also different. Therefore, the theoretical amount of glue is different from the actual amount, and the actual amount is difficult to control. In general, the actual glue consumption is greater than the theoretical glue consumption. If the glue supply is significantly lower than the theoretical calculation glue consumption, it is necessary to consider whether to mix other brands of products. In the construction project, we need to supervise and use the sealant as much as possible to reduce waste.
