Net rack node location adjusting device and location adjusting method

Abstract

The invention belongs to the technical field of steel structures and in particular relates to a net rack node location adjusting device and location adjusting method. The net rack node location adjusting device comprises a bottom plate, a central round hole is formed in the bottom plate, a supporting tube is fixedly arranged on the bottom plate, an adjustable carrier tube is in threaded connection in the supporting tube, the adjustable carrier tube can move up and down relative to the supporting tube, a cross locating plate is arranged at the upper end face of the adjustable carrier tube, and the vertical downward projection of the center of the cross locating plate coincides with the central round hole of the bottom plate. When the net rack node location adjusting device is used for carrying out spherical node location, a coordinate converting method is utilized, and accurate location of spherical nodes can be achieved by measuring the coordinates of the central point of the cross locating plate. The net rack node location adjusting device and location adjusting method are convenient and effective for location and installation of the spherical nodes of net rack structures.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and in particular relates to a grid node positioning adjustment device and a positioning adjustment method, which are mainly aimed at the positioning, installation and adjustment of space structure engineering grid nodes in the construction steel structure industry. Background technique [0002] In the field of building steel structures, the grid structure is often favored by engineers because of its large space rigidity, good integrity, and good seismic performance. Because of this, grid structures are widely used in engineering. [0003] The grid structure can be divided into double-layer grid and three-layer grid according to the number of chord layers. Due to the large number of grid members, a large number of nodes are generated when the members meet. The quality of node positioning will have a considerable impact on the mechanical performance of the grid structure and the fabricat...

AI Technical Summary

Problems solved by technology

Since the sphere is a full-circle closed section, its outer surface is smooth and round, so it cannot be easily positioned during installation, which brings certain difficulties to the measurement work

Difficulty in the positioning of grid nodes will lead to inaccurate node positioning and errors in node positioning. For welded ball nodes, there will be uneven gaps between the intersecting openings of the rods and the surface of the ball. One side of the gap is large, and the other side may stick Tightness, leading to welding difficulties, the quality of joint welds is difficult to be guaranteed, which will cause unnecessary hidden dangers to structural safety; for bolted ball joints, there will be problems such as difficulty in installing rods
