Exterior wall thermal insulation on the use of time how to calculate the use quantity
outer wall heat preservation nail is in the building wall junction insulation board and application, used to prevent falls off insulation board, better fixed with wall body, combined with effective measures and guarantee. Of exterior wall thermal insulation for heat preservation nail is the anchor pieces, by galvanized screws, nylon tube rises and the fixed wafers.
depending on the insulation layer thickness, heat preservation nail is divided into a variety of specifications and types. Mild steel are: the external wall insulation nails, insulation nails, lu: su insulation nails, nail stickers heat preservation, plastic expansion, wall insulation fixed screw, etc. Specific model professional manufacturers can according to customer's special requirement.
exterior insulation system heat preservation nail installation number; Nylon anchor fixed ( XPS board, for example) Layer 7 the following per square meter about four, eight 18 layer around 6 per square meter, 19 - 28 layer about 9 per square meter, 28 floors above 11 per square meter, any area is greater than zero. 1 ㎡ single boards are plus fixed components, Yang Angle hole edge encrypted separately.
other insulation materials such as EPS board, mineral wool board and use according to the number of anchor bolt plate shearing resistance or increase or decrease the tensile force, to safeguard anchor tension is greater than the safety factor of 5 metope place negative wind pressure design.
