ABSTRACT:
An arrangement for guiding casting forms, which comprise a so-called working plane (1) in the form of, for example, a beam system, which is capable to support two casting form halves (3,4), between which concrete is intended to be poured. The casting forms further comprise a yoke (11) supported on legs (12), which yoke has the design of, for example, a frame with two preferably mutually parallel, substantially vertical sides (12) and one side (11) located intermediate and perpendicularly to said sides. The yoke (11) preferably is located above the working plane (1) and rigidly connected to the working plane (1).
According to the invention at least two guide bridles (14,23) in the form of, for example, strip iron, and a friction device (17) are provided. The guide bridles (14) are intended to be rigidly anchored at one end (15) preferably in a ground level plane (16). The guide bridles are extendible and with maintained tension therein to be attached by said friction device (17) also to the yoke (11) connected to the working plane (1), in order to stay a casting form in a vertical plane or in a plane forming an angle with the vertical plane.
