Device for forming wall lead-throughs in concrete construction work

摘要

In a device for forming wall lead-throughs in concrete construction work, which exhibits a hollow body (11) and two retaining parts which can be inserted into the ends of said hollow body, one retaining part is a supporting body (1) with a through-passage hole for a fixing bar (31). The latter is designed as a screw at the front end. An actuating member (36) is arranged or can be attached at its rear end. The other retaining part is formed by a load-bearing body (21) which is provided with a through-passage hole for the front end of the fixing bar (31). On its inner side, the load-bearing body (21) may exhibit a guidance arrangement for the front end of the fixing bar (31). <IMAGE>
