Description

Изобретение относитс к строительству и предназначено дл перекрыти большепролетных промышленных, гражданских и сельскохоз йственных зданий.The invention relates to construction and is intended to span large-span industrial, civil and agricultural buildings.

Известно вис чее покрытие, включающее опорный контур, закрепленный на опорах , и систему вант, размеш,енных параллельно одной из диагоналей покрыти , на которых смонтированы несуш.ие кровлю арки 1./A viscous covering is known, including a support contour fixed on supports, and a system of cables placed parallel to one of the diagonals of the covering on which the roof of the arch 1 is mounted. /

У такого покрыти повышенна деформативность при воздействии неравномерно распределенных нагрузок.Such a coating has increased deformability when exposed to unevenly distributed loads.

Известно также вис чее покрытие, включающее систему вант, подвешенных вдоль одной диагонали здани , на которых уложены неразрезные балки 2.A hanging covering is also known, including a system of cables suspended along one diagonal of the building on which continuous beams 2 are laid.

У этого покрыти невысока жесткость.This coating has a low stiffness.

Наиболее близким техническим решением к предлагаемому вл етс вис чее покрытие зданий и сооружений больших пролетов , включающее в себ опоры, на которых расположены ванты, и второстепенные несущие элементы в виде неразрезных щтампованных балок из листовой стали и плиты покрыти 3.The closest technical solution to the present invention is a viscous covering of buildings and structures of large spans, including the supports on which the shrouds are located, and secondary supporting elements in the form of continuous shtampirovanny beams made of sheet steel and a slab of coating 3.

Однако у известного покрыти повышенна деформативность при воздействии неравномерно распределенных нагрузок, так как ванты работают как абсолютно гибкие нити, и дл уменьшени деформативности покрыти в продольном направлении его необходимо пригружать собственным весом, в результате чего увеличиваетс расход металла на ванты.However, in a known coating, there is an increased deformability when exposed to unevenly distributed loads, since the cables work as absolutely flexible threads, and to reduce the deformability of the coating in the longitudinal direction, it is necessary to load it with its own weight, as a result of which the metal consumption on the cables increases.

Цель изобретени - уменьшение расхода металла и снижение деформативности покрыти при неравномерно распределенных нагрузках.The purpose of the invention is to reduce metal consumption and reduce the deformability of the coating under unevenly distributed loads.

Эта цель достигаетс тем, что в предлагаемом вис чем покрытии, включающем опоры , прикрепленные к ним ванты, балки и плиты покрыти , ванты выполнены в виде нитей, установленных с зазором одна над другой, и соединены хомутом, а плиты покрыти размещены между нит ми вант, причем балки размещены под вантами и прикреплены к нижним нит м на подвесках.This goal is achieved by the fact that in the proposed coating, which includes supports, the cables attached to them, the beams and the slabs of the coating, the cables are made in the form of threads installed one above the other with a gap, and the clamps are placed between the threads , moreover, the beams are placed under the cables and attached to the lower yarns on the suspensions.

Claims

Such a constructive implementation of the coating ensures the work of the guys as rigid threads due to the fact that the plates of the coating. The gap between flByMfr cables, the cut of the main enclosing functions, is performed by means of tight grip, the function of locks of cables in the vertical plane, and due to the suspension of the beams on the lower cables, which, in turn, are connected to the upper ones. The transformation of a flexible HHtfr B WtKyio occurs as a result of the separation of a flexible thread into two flexible threads and their separation in height by a distance equal to the height of the cover. FIG. 1 shows the described pokr1tie, transverse section; in fig. 2 — node I in FIG. one; in fig. 3- section A-A of FIG. 2; in fig. 4 - the same, top view. The lower surface includes supports 1, cables 2, continuous beams 3, and slabs 4 of the coating. The guys 2 are placed with a gap equal to the thickness of the plate 4 and the combusions 5. The gap between the cables 2 is fixed by the pads 6 attached to the plates 4 of the cover. The beams 3 are placed under the lower cables, on the suspensions 7. The top coating is mounted as follows. The supports 1 pull the upper and lower vanes 1 to 2. 2. On the lower vanes 2, pendants 7 are visited, on which continuous beams 3 are installed. Above the beams 3 plit T 4 covers with overlays 6 are placed. At the same time, the cables 2 are placed in the seams between the plates 4 cover The combination of the coating plates and cable ties is ensured by clamps 7, which are visited on the upper and lower cables 2 in the grooves between the slabs and after tightening the nuts, the cables and the coating plates are combined into a single design. This design of a hang coating allows a 1.8-fold decrease in the deformability of a hang coating with unevenly-defined loads and a 25% reduction in metal consumption per guy. Claims of buildings and structures, including supports, cables, beams and slabs attached to them, characterized in that, in order to reduce metal consumption and reduce deformability of the coating with unevenly distributed loads, the sleeves are made in the form of threads installed with a gap one on another, and connected by clamps, and the slab of coating is placed between the threads of the cables, with the beams placed under the cables and attached to the lower threads on the hangers.
