DEVICE IN A BUILDING STRUCTURE
The present invention relates to a device in connection with building structures, especially for supporting structures which by their net weight or by varying loads are subjected to deformation. Especially in connection with large roof structures one is enfaced with the problem that deformations due to net weight or variable natural loads give rise to so large deformations that irregularities are created in relation to adjacent building elements, in first instance walls or larger gates, especially drive-gates for hangars, workshops, etc. These problems are alleviated by a device comprising one or more displacement means (7) which by global displacement of the roof supporting members (2) neutralize the sum of local deformations in the critical points of the structure, for example at the supporting rail (4) for drive-gates (5). Such displacement means can also be used for eliminating the horizontal displacement of said supporting members.
