The present invention relates to a wall body coupling structure using an exterior composite panel coupled to a super-slim stone plate in an insulation panel unit. An exterior insulation composite panel (300M) is fixated by a panel fixating angle (530) at a middle point from both sides to be connected to an exterior insulation composite panel (500M) at upper and lower sides while forming a uniform interval on an exterior wall surface of a building. The exterior insulation composite panel (300M) is formed after an insulation panel unit (310) and a super-slim stone plate (320) are bonded. The exterior insulation composite panel (500M) is formed after an insulation panel unit (510) and a super-slim stone plate (520) are bonded. The exterior insulation composite panel (300M) and the exterior insulation composite panel (500M) formed at the lower side are coupled after a downward hanging unit coupling fastener (540) and an upward hanging unit coupling fastener (550) are respectively inserted into a panel latching groove (311) and a stone latching groove (321), formed at a lower portion of the insulation panel unit (310), and a panel latching groove (511) and a stone latching groove (521), formed at an upper portion of the insulation panel unit (510). Furthermore, the panel fixating angle (530) is coupled to the downward hanging unit coupling fastener (540) and the upward hanging unit coupling fastener (550) to be fixated on a wall body (W) by an anchor bolt (560).

본 발명은 외단열복합패널(300M)이 건물의 외벽 벽면에 일정한 간격을 형성하면서 상하로 외단열복합패널(500M)과 연결되기 위하여 양측 중간지점에서 패널고정앵글(530)에 의하여 고정되며, 상기 외단열복합패널(300M)은 단열패널유닛(310)과 초슬림석재판(320)의 접합에 의하여 형성되고, 상기 외단열복합패널(500M)은 단열패널유닛(510)과 초슬림석재판(520)의 접합에 의하여 형성되며, 상기 외단열복합패널(300M)과 하부에 형성되는 상기 외단열복합패널(500M)의 결합은 단열패널유닛(310)의 하부에 형성된 패널걸림홈(311) 및 석재걸림홈(321)과, 단열패널유닛(510)의 상부에 형성된 패널걸림홈(511) 및 석재걸림홈(521)에 각각 하향걸이부용체결파스너(540)과 상향걸이부용체결파스너(550)이 끼워지고, 상기 하향걸이부용체결파스너(540)과 상향걸이부용체결파스너(550)에 패널고정앵글(530)이 결합되어 벽체(W)에 앵커볼트(560)에 의하여 고정되는 것을 특징으로 하는 단열패널유닛 및 이에 초슬림석재판과 결합된 외장용 복합패널을 이용한 벽체 결합구조이다.
