A series of box-like structures constituting a convex connection structure and a method for constructing the convex connection structure

摘要

Problem to be solved: to provide a box like structure and a construction method for reducing the time of construction and the cost of the construction of an arch structure of a large roof or a bridge using a series of box structures constituting a convex connection structure without requiring any support.The construction method of the arch or the convex connection structure does not adopt a support.A series of box shaped structures 1A are arranged on the base 1b, and a space opened downward between the box shaped structures is provided.The tension member 4a is disposed through a series of box shaped structures, and the tension of the tension member is narrowed so that the space opened down is narrowed, and the box like structure located at the central portion is lifted up to form an arch or convex type.After forming the shape, a solid material is injected into the box like structure to construct a more strongly convex structure.Diagram
