Abstract

The invention discloses a multi-layer large-span fabricated orthogonal spatial concrete space grid box-type structure and a manufacturing method. A peripheral supporting structure system of prefabricated large-span orthogonal spatial concrete hollow floors is changed into a concrete grid type framework with dense columns and dense beams from a concrete framework structure formed by casting of large column grids in site, and it is required that the sizes of floor grids are equal to the sizes of dense column grids. Small connecting beams are arranged at an upper window opening and a lower window opening of each layer of dense columns except connecting beams at the floor, so that the peripheral supporting structure system is changed into the grid type framework from the framework, and lateral resisting stiffness of the structure is improved by a large margin under the premise that structure materials are decreased. Because the transverse floors and the vertical supporting system both are composed of grids, the structure system is changed into the novel orthogonal spatial space grid box-type structure system of a mechanical model with plates.

Description

technical field

[0001] The invention relates to a multi-layer large-span assembly type orthogonal and vertical assembly type concrete space grid box structure and a manufacturing method, and belongs to the technical field of multi-layer public buildings. Background technique

[0002] For a long time, the structural system of buildings has remained in the frame, frame, shear and frame tube structure, especially multi-storey long-span buildings, such as sports buildings, the first floor is basketball and volleyball; the second floor is gymnastics; The third floor is for table tennis training, and its floor span is L y =30m, length L x =37.5m, aspect ratio L x / L y = 1.25. According to the traditional structural system, the floor along the short direction (L y =30m) is set as a reinforced concrete frame beam, along the length (L x =37.5m) Concrete beams are set every 3.75m between the frames, and the upper part is a concrete floor slab, each floor slab is 7500×3750, and i...
