Prefabricated reinforced concrete monolithic frame of the building

摘要

The invention relates to the field of construction, in particular for prefabricated monolithic frame, and can be used in the construction of high-rise residential and public buildings. The technical problem is to increase the reliability of reinforced concrete prefabricated monolithic frame. The problem is solved in that, in a frame comprising columns rigidly connected to the monolithic bolts, which by concrete anchors are simply supported prefabricated hollow-core slabs, the hollow-core slabs are provided with frames which are positioned in their supporting zones and configured releases longitudinal reinforcement rigidly fixed in each block-bolt, wherein the width of each monolithic pins is determined by the formula:; .; where: b _p - width pins, m;; b _k - the width of the column, m;; The _p - Step bolts, m;; M - torque limit perceived monolithic cross section view of a crossbar with a thrust of columns × N m;; q - the linear load on the calculated overlap, N / m.; The inventive reinforced concrete prefabricated monolithic structure, compared to the prototype, allows to increase its reliability by 10-20% in the odd increase the bearing capacity of overlap, which is achieved by reducing the voltage in the cross sections of spans and a modular joint of hollow-core slabs, due to the decrease of reference points, relating to modular joint with monolithic hollow-core bolt, and also increase the peel strength of modular shelves hollow-core slabs. 5 yl.
