本发明涉及一种用于屏蔽深沟槽的装置，其包括：立柱（1,2），其沿沟槽以规则间隔成对放置; 所述隔离框架（6）将一对支柱的杆（1,2）保持分开并且在所述支柱（1,2）上可滑动地引导。 以及其边缘可在支柱（1和2）的导向通道（3）中滑动的大面积屏蔽板（4）。 立柱（1和2）具有两个侧壁（31），它们与外壁（30）和内壁（34）一起形成中空箱形轮廓。 为了在柱和撑杆框架之间获得可靠的导向和动力传输以及使用少量材料的高负载能力，柱（1,2）的侧壁（31）延伸 在内壁（34）上方的内部和保持凸缘（32）被放置在它们的突出端（31'）处以形成引导通道（3）。 在侧壁（31）的突起（31'）之间形成有形状上在间隔框架（6）的两个前侧上正确地抓住导轨（40）的导槽（18）。 在保持凸缘（32）的外侧上滚动的滚子（12）被容纳在所述轨道（40）的两侧上的间隔框架（6）上。

The invention relates to a device for shielding deep trenches, comprising: posts (1, 2) vertical in place by two at regular intervals along the trench; spacer frames (6) which maintain the distance poles (1, 2) of one pair of poles and which are guided sliding on the posts (1, 2); and shielding plates (4) large area whose edges are displaceable in guide channels (3) poles (1 and 2). The posts (1 and 2) have two side walls (31) which form a box hollow profile together with an outer wall (30) and an inner wall (34). In order to get a guide and a reliable power transmission between the posts and the spacer frames and a high load capacity by using fewer materials, the side walls (31) of the posts (1, 2) extend inwardly above the inner wall (34) and holding flanges (32) are placed at their projecting ends (31 ') to form the guide channels (3). A guide channel (18) which engages by form fit a rail (40) located on both sides before the spacer frame (6) is formed between the projections (31 ') of the side walls (31). Rollers (12) rolling on the outer sides of the holding flange (32) are mounted on the spacer frame (6) on both sides of said rail (40).
