本发明涉及一种用于teilauskragende组分（B），例如在外壁（5）的与外部相互热绝缘（W）的壁开口（4）的窗口（F）和门的壁安装系统，其中所述壁开口（4）具有一个拱腹（6） 是在相应的teilauskragende（B）成分固定承重。 因此，组分（B）简单并避免从壁开口进一步的热桥（4）teilauskragend到揭示（6）可以安装，所以建议在外壁的外侧（5）和对齐或近似对齐，即，特别是至少在 基本上到揭示（6）对准提供了用于的揭示侧向稳定的附接元件（2）（6）。

The invention relates to a wall installation system for teilauskragende components (B), such as windows (F) and doors, in a wall opening (4) of an outer wall (5) with the outside mutual thermal insulation (W), wherein the wall opening (4) having a reveal (6) , is at the respective teilauskragende component (B) fixed load-bearing. Thus, a component (B) uncomplicated and to avoid further heat bridges from the wall opening (4) can be teilauskragend mounted on the intrados (6), it is proposed that the outside of the outer wall (5) and aligned or approximately aligned, ie in particular at least in the substantially to the reveal (6) is provided an attachment element (2) for the lateral stabilization of the reveal (6) in alignment.
