Research and discussion about wind resistance performance of exterior wall insulation system based on compound board with insulation and decoration
The exterior wall insulation system based on compound board with insulation and decoration is widely used in the field of external wall insulation,and its wind resistance performance research has significant theoretical significance and practical value.This paper calculates the wind load design values of the external insulation system of the integrated insulation and decoration board for exterior walls in Beijing area based on the relevant provisions of the Load code for the design of building structures(GB 50009-2012),Technical code for glass curtain wall engineering(JGJ 102-2003).The shear bearing capacity of notches of ceramic thin plates,marble slabs,and calcium silicate slabs with different thicknesses under the action of different lengths of anchor cards is tested,and the value of the panel thickness is given.A comparative study is conducted on the wind load resistance performance and anchor connection failure mode of ceramic thin insulation decorative integrated board and base wall using pure anchoring and adhesive anchoring combination connection methods,and finite element analysis is conducted.The results indicate that the integrated insulation and decoration board with the base wall are connected with adhesive anchors equally,and the independent and safe anchoring method is feasible and applicable.The design value of the anchoring connection should be based on the standard value of single-point anchoring force.When anchorage is designed independently and safely,the decorative panel with appropriate thickness shall be selected to ensure that its flexural strength and notch shear strength are not less than the standard value of wind load for pure anchorage connection.When the external thermal insulation system of insulated decorative panels with thin ceramic is connected with the concrete base by adhesive anchors,with sufficient safety margins.
