Baotou GRC The slab has the characteristics of simple construction, convenient design, short cycle, light weight, etc., and can flexibly design different shapes. Therefore, most people like it and choose it when decorating GRC Series products. How is the GRC board installed? How to control the error of GRC sheet during installation and positioning?
1) Positioning and setting out: during GRC installation, the total station shall accurately set out at least three GRC fixed points according to the coordinate control points in the engineering drawings.
Specific test method: select three-dimensional lofting method:
① Quickly clean the embedded components, measure the datum axis and the boundary line;
② The center line position of the support point is measured by the middle middle middle edge cycle measurement method;
③ Correct and locate the spacing of each centerline;
④ Measurement and correction of basic datum horizontal line.
The GRC board is fixed and connected by two points and two points. When installing the panel, first enter the limit point, and then insert the GRC board connector into the limited gap between the GRC board and the flexible waterproof layer with manual tools for adjustment, so that the GRC board is installed in strict order.
GRC boards are manufactured and processed in accordance with the block sequence set out in the construction plan when they are processed in the processing plant. They should be installed in the order set out in advance. The general order is from bottom to top, from top to top. Avoid leaving gaps during construction, or excessive accumulated errors may be caused, which may make the gaps between GRC plates unsmooth.
