Tension construction method and construction tooling of grid steel tie rods

Abstract

The invention discloses a tensioning construction method and construction tooling of grid steel tie rods. The tensioning construction method of grid steel tie rods includes setting tensioning tools on grid nodes, installing tensioning equipment on the tensioning tools; The two ends of the tie rods are respectively connected to the nodes of the network frame; tensioning is carried out through the tensioning equipment until the preset tension is reached; the tensioning equipment is removed; the construction tooling for the tensioning of the steel tie rods of the network frame includes the connection for installing the tensioning equipment ontology. When the tensioning equipment in the embodiment of the present invention is stretching the network frame, the steel tie rod group is also subjected to the tension force applied by the tensioning device to the network frame and deformed, and the tension force of the tensioning device is gradually transferred to the steel tie rod group , after the unloading of the tensioning equipment is completed in the grid stretching, the degree of internal stress change of the steel tie rod group after the unloading of the tensioning equipment is reduced, and the tensioning tooling on the grid nodes can also be applied to other constructions after the unloading of the tensioning equipment Craftsmanship, versatility and practicability are good.

Description

technical field [0001] The invention relates to a network frame construction method, in particular to a network frame steel tension rod tensioning construction method and construction tooling. Background technique [0002] With the development of space structures around the world, grid structures have been gradually applied to buildings that require large spans and large spaces due to their high-efficiency mechanical properties and novel and beautiful appearance. Prestressed and stretched to make the grid form a structurally stable spatial structure. Before the grid frame is stretched through the steel tie rods, special design for the tooling is required for the tensioning. The tooling is a one-time tooling and cannot be used in other tensioning construction projects. During the pulling process, the rod body is not deformed by force. After the tensioning tool is unloaded, the stress in the rod body of the steel tie rod is redistributed, and the tension and deformation of th...

Before the grid frame is stretched through the steel tie rods, special design for the tooling is required for the tensioning. The tooling is a one-time tooling and cannot be used in other tensioning construction projects. During the pulling process, the rod body is not deformed by force. After the tensioning tool is unloaded, the stress in the steel tie rod body is redistributed, and the tension and deformation of the steel tie rod are difficult to measure.
