Abstract

FIELD: civil engineering. SUBSTANCE: prefabricated roofing of a building has metal support structure with reinforced slabs put on it. The slabs are connected to the support structure through grouted plugs formed in holes placed in the slabs in points of their resting on metal structure. Slab holes are originated by hollow steel members of tubular cross section with height equal or exceeding the thickness of the slab, and minimum dimension of the cross section is specified as $$$, where "a" is minimum dimension of the cross section, "h" is slab thickness. Before grouting the hollow steel member is welded to metal support of the structure with its lower face. Stopper welded to the hollow steel member before grouting may be welded to the upper surface of the metal structure. The hollow steel member may be made in the form of upset truncated cone or in the form of rectangle with long sides placed along metal support structure, and welded joint is laid on short sides. EFFECT: high strength. 5 cl, 7 dwg

Цель: для соединения железобетонных плит перекрытия с верхним поясом шпренгельной формы. Сущность: сборные покрытия здания содержит металлическую опорную конструкцию, на которую уложены железобетонные плиты, соединенные с опорной конструкцией замоноличенными пробками, образованными в отверстиях, расположенных в плитах в местах их опирания на металлическую конструкцию. Отверстия в плитах образованы полыми стальными элементами трубчатого сечения, высота которых равна или превышает толщину плиты, а минимальный размер поперечного сечения "в свету" определен по формуле a ≥ h/2, где a - минимальный размер поперечного сечения "в свету", h - толщина плиты. Полый стальной элемент перед замоноличиванием приварен изнутри к металлической опорной конструкции своим нижним торцом. К верхней поверхности металлической опорной конструкции в зоне установки полого стального элемента может быть приварен фиксатор, соединенный перед замоноличиванием с полым стальным элементом на сварке. Полый стальной элемент может быть выполнен в виде опрокинутого усеченного конуса или в виде прямоугольника, длинные стороны которого расположены вдоль металлической опорной конструкции, а сварной шов уложен на коротких сторонах, причем продольные грани могут иметь трапецеидальную форму.Purpose: for joining reinforced concrete floor slabs with a top truss shape belt. SUBSTANCE: prefabricated building coatings contain a metal supporting structure on which reinforced concrete slabs are connected, connected to the supporting structure by monolithic plugs formed in openings located in the plates in the places of their abutment on the metal structure. The holes in the plates are formed by hollow steel elements of tubular section, the height of which is equal to or greater than the thickness of the plate, and the minimum cross-sectional dimension "in the light" is determined by the formula a ≥ h / 2, where a is the minimum cross-sectional dimension "in the light", h - plate thickness. Before monolithic, the hollow steel element is welded from the inside to the metal supporting structure with its lower end. A fixer can be welded to the upper surface of the metal support structure in the installation area of the hollow steel element, which is connected before welding with the hollow steel element in welding. The hollow steel element can be made in the form of an overturned truncated cone or in the form of a rectangle, the long sides of which are located along the metal supporting structure, and the weld is laid on the short sides, and the longitudinal faces can have a trapezoidal shape.
