Outer thermal insulation wall with mechanically anchored metal mesh reinforced polystyrene boards

Abstract

The invention relates to an outer thermal insulation wall with metal mesh reinforced polystyrene boards anchored by a mechanical fixing device. By utilizing the leveling and binding layer on the foundation wall, before the leveling layer is dried, the metal mesh reinforced boards for thermal insulation are bound on the leveling layer to perform the functions of auxiliary connection and stabilization, thereby ensuring the flatness of the polystyrene boards. Holes are drilled in the board surface, and the metal mesh reinforced polystyrene boards for thermal insulation are directly fixed on the foundation wall through plastic expansion anchor bolts, so that all the load on the outer thermal insulation system is completely borne by the fixing anchor bolts and transferred to the foundation structural wall. The organic combination of the anchor bolts and the reinforced polystyrene boards can perform the auxiliary stabilizing function on the load on the leveling layer of the wall. Therefore, the outer thermal insulation wall is especially suitable for outer thermal insulation energy-saving modification works on outer walls of buildings, and can well solve the technical problems of low bearing capacity and difficult surface treatment in the old foundation of the outer wall.

Description

Technical field [0001] The invention relates to an external thermal insulation wall of an external wall in which a mechanical fixing device anchors a metal mesh-reinforced polystyrene board, and is especially suitable for energy-saving renovation projects of existing building external walls. Background technique [0002] The existing polystyrene board external thermal insulation wall is a composite wall formed by combining the base wall and the polystyrene board, and the polystyrene board is fixed on the base layer with an adhesive as the insulation layer. This structure requires the adhesive to bear all the loads of the external insulation system, and at the same time transfer the loads to the structural walls through the wall screed. However, due to the unevenness of the base layer of the wall or the unevenness of the insulation board, the insulation board may leave a hidden danger to the quality, safety and stability of the entire external insulation wall. In addition, w...
