Title:
STRING OF BOX-SHAPED STRUCTURES CONSTITUTING CONVEX CONNECTION STRUCTURE AND CONSTRUCTION METHOD FOR CONVEX CONNECTION STRUCTURE
Document Type and Number:
Japanese Patent JP2019094736
Kind Code:
A
Abstract:
To provide a box-shaped structure and a construction method using it, with which the usage of a string of the box-shaped structures to constitute a convex connection structure for constructing a large roof or an arch structural body of a bridge eliminates the necessity of supporting and reduces the construction period and cost.SOLUTION: A construction method for arches or convex connection structures in this invention does not use supporting. A string of box-shaped structures 1a are lined up on a base 1b, having spaces each of which expands downward between the box-shaped structures. A tensile member 4a is arranged through the string of box-shaped structures. Tensing the tensile member closes the spaces opened downward, and makes the box-shaped structures located in the middle part afloat forming an arch or a convex figure. Upon a target figure being formed, hardening material is filled in the box-shaped structures to early construct a stronger convex connection structure.SELECTED DRAWING: Figure 2
