An external insulating wall provided with a polystyrene laminate with a man-made fiber grid reinforcer anchored by a mechanical fixing device, comprising: a leveling binder layer applied on a basic layer wall, a reinforced polystyrene laminate 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 basic layer wall by 3˜9 mm in thickness for forming said leveling binder layer, said leveling binder layer on the basic layer wall is once-shaped for ensuring that said reinforced polystyrene laminate is flat, said reinforced polystyrene laminate with a two-dimensional man-made fiber grid reinforcer disposed under a surface layer thereof is mounted on the basic 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 basic 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 original basic layer is solved by said reinforced polystyrene laminate with efficient help of said plastic expansion anchor bolts, in addition, the basic layer wall is enhanced and protected for increasing stability; a man-made fiber grid reinforcer formed by two-dimensional man-made fiber is disposed under a surface layer of said reinforced polystyrene laminate with man-made fiber grid reinforcer, said reinforced polystyrene laminate is 800˜1600 mm in length and 400˜800 mm in width; a distance between said plastic expansion anchor bolts in horizontal and vertical directions is 250˜450×250˜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 basic 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.
16. The external insulating wall provided with a polystyrene laminate with a man-made fiber grid reinforcer anchored by a mechanical fixing device, as recited in claim 15, wherein said reinforced polystyrene laminate with man-made fiber grid reinforcer is optimally 1200 mm in length, and optimally 600 mm in width, said distance between said plastic expansion anchor bolts is optimally 300˜400×300˜400 mm.
