METHOD FOR ERECTION OF MULTISTORY FRAMEWORK BUILDING Russian patent published in 1999 - IPC

Abstract RU 2137886 C1

FIELD: construction engineering. SUBSTANCE: method can be used for erection of monolithic buildings and structures. According to method, columns and coverings are concreted in shuttering of each story with creation in coverings of open passages in mutually perpendicular directions for location of prestressed reinforcement by installing hollow-core forming mandrels in shuttering. Open passages in coverings are made of varying depth with incline towards center of each framework span to value equal to depth of covering. Upon hardening of concrete, shuttering is removed and hollow-core forming mandrels are taken away and then installed for concreting next story of framework. Installed in open passages along faces of columns in compliance with epure of bending moments is prestressed reinforcement. Reinforcement is tensioned by hydraulic jacks and fixed on end-faces of coverings over perimeter of building framework. After that, open passages in covering are concreted. Application of aforesaid method cuts labour input in manufacturing of framework, cuts erection period and improves quality of construction operations. EFFECT: higher efficiency. 2 dwg
