Claim:
An external insulating wall provided with a polystyrene laminate with a metal grid reinforcer anchored by a mechanical fixing device, comprising: a leveling binder layer applied on a base layer wall, reinforced polystyrene laminates applied on said leveling binder layer, a plurality of plastic expansion anchor bolts applied in said reinforced polystyrene laminate, a thin surface protecting layer applied on said reinforced polystyrene laminate and a decorating layer applied on said thin surface protecting layer, wherein puttying polymer mortar is applied on the base layer wall by 3-9 mm in thickness for forming said leveling binder layer, said leveling binder layer on the base layer wall is once-shaped for ensuring that said reinforced polystyrene laminate is flat, said reinforced polystyrene laminate with a two-dimensional metal grid reinforcer disposed under a surface layer thereof is mounted on the base layer wall at the same time for forming a thermal insulation layer without void, a side with reinforcer of said reinforced polystyrene is set outwardly, said reinforced polystyrene laminates are arranged in a horizontal rectangle form, perpends of said reinforced polystyrene laminates are in a running bond form, a distance between said perpends is optimally 400 mm or 600 mm in module for taking full advantage of anchoring effect of said plastic expansion anchor bolts applied in said perpends; said reinforced polystyrene laminate is directly fixed on the base layer wall by said plastic expansion anchor bolts through holes drilled on a surface of said reinforced polystyrene laminate, a tension load limit and stability of an external thermal insulation system is increased and a problem that gluing strength does not meet requirement because of flaking, cracking and polluted decorating layer of the base layer is solved by said reinforced polystyrene laminate with efficient help of said plastic expansion anchor bolts, in addition, the base layer wall is enhanced and protected for increasing stability; the metal grid reinforcer formed by electric welding decussations of longitudinal steel wires and transverse steel wires is disposed under a surface layer of said reinforced polystyrene laminate with metal grid reinforcer, said reinforced polystyrene laminate with metal grid reinforcer is 800-2400 mm in length and 400-1600 mm in width; a distance between said plastic expansion anchor bolts in horizontal and vertical directions is 200-450×200-450 mm, a number of said plastic expansion anchor bolts is no less than 8 per square meter, a number of said plastic expansion anchor bolts applied in each of the perpends is no less than 3 with a distance of no more than 400 mm, said plastic expansion anchor bolts should be applied in every edge and corner of said reinforced polystyrene laminate for ensuring stability thereof; the base layer wall is a concrete wall, an aerated concrete block wall, a solid brick wall, a hollow brick wall or a light-weight cement wall.
