Exterior wall insulation construction method is introduced
a variety of different are used in building exterior wall thermal insulation heat preservation material, but no matter choose what kind of material, heat preservation nail as the anchoring piece, are indispensable, in concrete construction, how to use the anchoring piece?
used in thermal insulation construction of thermal insulation nails, on drilling method, the construction unit can choose to rotary drilling, no impact or hammer. What drilling methods: building materials decided to use ordinary solid building materials selected for impact drilling and hammer drilling; Hollow brick and low strength of building materials and aerated concrete is suitable for using rotary drilling method. In the margin on the determination of spacing, tapping type nylon anchor should satisfy is greater than or equal to 2 H and spacing is greater than or equal to 4 H, among them, the H refers to the anchoring depth. The anchoring depth refers to the part from bearing stratum to anchor inflation to the edge of the distance, thickness by anchor bolt anchorage, the thickness of the insulation material should be considered, bonding layer and the thickness of the bearing stratum. The depth of the hole should be bigger than the anchoring depth at least 10 mm. On the installation method, generally USES the transmission installation, by the anchor solid insulation system of the hole diameter and hole diameter is the same as base material, anchor bolt through by anchoring a push into the hole, expansion effect and bearing.
