摘要： An arrangement for use when casting concrete floors, particularly in locales having pillars, floor drains or the like. The arrangement includes straight concrete beams and sections of ring-like concrete beams which are intended to be incorporated in the resultant floor. The ring sections are arranged to coact in order to completely encircle a free-standing pillar or the like, or to partially encircle a pillar located adjacent a wall. The sections are provided with a lower support flange intended to support the ends of the straight beams. The height of the straight beams is so selected in relation to the height of the ring-like beams that when the straight beams rest on the aforementioned support flange, the upper surfaces of both kinds of beams are located in a common plane, on a level with the resultant floor surface, in order to be able to serve as support paths for concrete smoothing devices. The application also relates to a method for manufacturing beams intended for use with the arrangement.

摘要： A method of simultaneously manufacturing a plurality of concrete beams having upper and lower flange parts which are separated by a web part and which extend over a whole length of the beams. The method includes the steps of providing a first form part constituting a bottom part including a plurality of elongate mutually spaced recesses where the recesses have a shape corresponding to the outer portion of the upper flange part of the beams and providing a plurality of elongate intermediate members having a plurality of projections extending from opposing sides thereof which are placed on the bottom part between the recesses such that the lines of contact between the intermediate members and the bottom part are displaced from the bottoms of the recesses. In this manner, when the concrete is poured into the chamber formed by the intermediate members and the bottom part, flash is not formed on the outer portion of the upper flange part of the beams formed by the first form part. Thus, the outer portion of the upper flange part of the concrete beam is smooth.

摘要： A method for levelling and smoothing concrete when concreting large areas. According to the method a machine which is so constructed that it floats lightly even on highly fluid concrete mass and thus normally exerts a very low surface pressure against the substratum, is caused to move over the surface of the concrete while smoothing and levelling the same as a result of rolling motion between the surface and a belt of the machine in contact therewith. The smoothing or levelling effect of the belt can be amplified by vibrating a plate supporting the belt. The concrete may also be subjected to vacuum treatment at the same time as levelling or smoothing the concrete. The invention also relates to a machine for carrying out the method.
