(2) corner protectors, holes, grooves, boxes and plastering surfaces around them should be neat and smooth; The plastering surface behind the pipeline should be smooth.
(3) The total thickness of plastering layer should meet the design requirements; Cement mortar shall not be plastered on the lime mortar layer; Shall not be plastered on the cement mortar layer.
(4) The setting of plastering frame joints shall meet the requirements, with the same width and depth, smooth surface and neat edges and corners.
(5) drip line (tank) should be adopted for the parts with drainage requirements. Drip line (trough) should be neat and straight, drip line should be high inside and low outside, and the width and depth of drip tank should not be less than 10 mm.
(6) The allowable deviation and inspection method of general plastering engineering quality shall comply with the provisions in the table below (construction according to the requirements of advanced plastering).
Extended data:
A, steel wire mesh specifications:
National standards have certain requirements for the specifications of steel wire mesh. The diameter should match the mesh size, not just the diameter. For plastering layer, the mesh should not be greater than 20×20, and the diameter should not be less than 1 mm, so it is meaningless to choose the diameter only. Choose 0.9×40×40 and 0.6× 10× 10 steel wire mesh. The role of steel wire mesh in plastering external wall is mainly a measure to prevent falling off from the perspective of safety, because of the location problem, the role of anti-cracking is relatively small.
Exterior wall external thermal insulation system adopts decorative tiles. As for the function, it should be anti-fall first and anti-crack second. In this case, the grid of 0.6× 10× 10 should be selected. These are some empirical choices. The conversion of the grid comes from the steel wire mesh specifications stipulated by the state, and the grade conversion of steel content is adopted.
Second, steel wire mesh related industry standards
The industrial standard of "Steel Wire for Woven Steel Wire Mesh" passed the examination and approval of Hangzhou Expert Group. Experts from the National Steel Standardization Technical Committee believe that the standard is based on the actual production of steel wire for woven steel wire mesh in China, with reasonable indicators, reflecting the principles of scientificity, advancement and operability, reaching the international advanced level and broad application prospects.
The Development and Reform Office of the National Development and Reform Commission listed the steel wire for woven wire mesh in the national ferrous metallurgy industry standard formulation plan for 2008-2009.
