Title: Pole type house construction - uses unloaded bearing structure with column foundations as structural elements
Inventor: LAUBKEMEIER FRIEDHELM
IPC: E04B1/34
Filed: 1976-04-12
Abstract: The pole or column type of house construction, with unloaded support structure, is designed for optimal load transfer. The columns also accommodate load and force moments resulting from unilateral traffic loading and wind stressing, for transfer to the foundations. For reduction of static forces acting on the support structure, the inertia forces of the external and internal walls (8, 9) are supported by foundations (5.1, 5.2) in the form of structural elements. The walls are retained by the support structure to check deviations from the vertical setting. Where the external and internal walls are in contact with the support structure (3.3, 3.8, 4.1, 4.2) a slidable wall guiding system in the vertical direction can be produced, preventing inertia force transfer from walls to support structure.
