An apparatus for facilitating the application of auxiliary agents for producing an upper boundary of a wall opening in the building and construction industry

摘要

The present invention relates to a device in order to facilitate the attachment of auxiliaries for the preparation of the upper boundary of a wall opening in the construction, such as, in particular, of lintels and a method in which such a device. The device comprises a carrier rail with a first main surface on which a first holding element and at a distance from it along the main axis of the carrier rail a second retaining element are mounted, wherein the second retaining element is mounted in movable manner. On the support rail by means of a tensioning device can be arranged in the second retaining element in relation to the first holding element, so that the device by a clamping action on one side wall of a wall opening can be temporarily securing. The carrier rail further has a side surface or a part of such a, which (r) is suitable as a bearing surface. The attachment of auxiliaries for the preparation of the upper boundary of a wall opening in the construction industry, such as squared timber or formwork. by means of a pair of such devices is, without costly preparatory work or complicated adjustment is possible and offers a considerable saving of time as compared to conventional procedures.n="43"
