HEATED low-rise buildings with a floor on warming the ground floors, erected on heaving subgrade

摘要

A heated low-rise building with a floor on warming ground overlap, erected on the heaving, subgrade with a depth of freezing is not more than 1.7 m, comprising weakly deepened foundations on a sand cushion under interior and exterior walls of the building, the sectional areas of the longitudinal and transverse reinforcement which define the bending points at non-uniform frost heaving base and side surfaces structurally protected against tangential forces frost heaving, ground floor on warming Overcoating , Interior and exterior walls with concrete belts placed at the bottom of the floor slabs, characterized in that the foundations for interior walls, exterior walls arranged transversely replaced beams simply supported on the outer bases, with the step of at least not more than 7.2 m and length of not more than 9.0 m, the area of ​​the longitudinal and transverse reinforcement to foundations outer determined taking into account the bending and torque determined by formuleM = Fe, wherein the torque M- 1 rm foundation at a distance from the transverse walls 0,51, where 1 - the distance between the transverse walls; F- resultant force frost heaving, kN load equal to 1 rm under the sole foundation of the building; e- distance from the resultant force to the surface plane of the basement, m anchoring the outer wall of the rotation base is carried out at a concrete ground thawing belts laid on the surface of the interior walls at the level of the bottom plate covering and are connected to zones on the outer walls, the cross section area of ​​the metal is determined by the anchor rods to the formula: a total area ankeruyuschi
