本发明涉及使用在建筑物的外壁（3）的建筑物入口的安装和用于在建筑物中引入的多条线，该建筑物引入分隔构件（1），其在结构上是通过用初始可流动成形和然后固化成型材料注射到建筑物外墙 （3）是集成的，然后通过孔形成多个（8），其中所述使用步骤还包括，在分隔构件的铸造（1）到每个通道开口（8），其中每个调度延伸的各自的通道开口的空管（11）的（8）之后 并且然后在至少一些所述导管（11）每个都具有线路中的至少一个被传递，其特征在于，（1）建筑物内部侧之间在铸造后分隔构件（6）延伸，并在建筑物外侧（7），由所述固化的成型材料分隔 通过开放（4）安排，美国 其中分隔构件1相对于垂直于其纵向轴线10的方向将通孔4分成多个通孔8。

The invention relates to the use of a building entry for installation in an exterior wall (3) of a building and for introducing a plurality of lines in the building, which building introducing a partition member (1) which is structurally by molding with initially flowable and then solidifying molding material into the building outer wall (3) is integrated, and then forming a plurality through-holes (8), wherein said use further comprises, after the casting of the partition member (1) to each of the passage openings (8) of which each scheduled an empty tube (11) extending the respective passage opening (8) and is then in at least some of the conduits (11) each have at least one of the lines is passed, wherein extending the partition member (1) after casting in a between a building interior side (6) and a building exterior side (7), delimited by the solidified molding material through opening (4) is arranged, and nd wherein the partition member (1) the passage opening (4) with respect to directions perpendicular to its longitudinal axis (10) in the plurality of through openings (8) can be subdivided.
