More particularly, the present invention relates to a peripheral structure adjacent to an opening for installing a window of an outer heat insulating wall having excellent thermal-bridge breaking property, airtightness, and nonflammability.

Generally, the construction of the window for the outer wall of the reinforced concrete structure is usually carried out by installing a window frame on the preformed opening when the concrete wall is constructed and supporting the window by installing a bracket on the end of the concrete wall, Outer insulation construction was carried out.

As an example of such a conventional method of constructing a window for a typical exterior wall, there are flashing of windows of an external-adiabatic building as described in Korean Patent Laid-Open Publication No. 10-2000-0006640 (published on Feb. 2, 2000) And a construction method.

6, a window frame (not shown) is directly installed on the inner periphery of a window installation opening formed in the concrete wall body 11, and on the outer surface of the concrete wall body 11, a primer mortar After forming the adhesive layer 12, a heat insulating material 13 made of an organic foaming material such as Styrofoam is adhered, a primer mortar adhesive layer 14 is formed on the wall surface of the window jaw 10, and a reinforcing mesh net 15 Called "dryvit", in which a primer mortar adhesive layer 16 is formed again after attaching the acrylic primer layer 16, then a chemical finish layer 17 containing acrylic synthetic resin having various textures, The window flashing 24 is positioned in the middle of the primer mortar adhesive layer 16 and the screw 21 is fixed to the fixing hole 24a by using an exterior insulation finishing system (EIFS) So as to prevent contamination of the outer wall due to rainwater.

However, the above-described conventional technique has a problem that the effect of blocking the heat bridge is inferior because the window is directly installed in the opening of the concrete wall body 11, and the heat insulating material 13, which is the organic foam board, It is inevitable to use adhesive layers 12, 14 and 16 mixed with a chemical organic adhesive and mortar, and since the strength reinforcing net 15 and the chemical finish layer 17 are used, It is vulnerable to an external impact, and in particular, there is a problem that a flame spreads in an instant when a fire occurs and a large amount of harmful smoke is generated.

Therefore, there is a need in the art for development of an opening edge structure of an outer insulating wall which is nonflammable to flame retardant and exhibits excellent heat insulation and airtight effect.
