Description

Technical Field

[0001] The utility model relates to the field of building steel structures, in particular to a two-section grid node ball rod member adjustment and fixing structure. Background Art

[0002] Steel structure grid is a spatial structure formed by multiple steel rods connected by nodes in a grid form. Its basic units include triangular grid, quadrilateral grid, hexagonal grid, circular grid, etc. These basic units can be combined into various forms such as triangular prism, cube, truncated quadrilateral cone, etc. to meet the needs of different buildings and facilities.

[0003] There are many steel structure grid components, and the accuracy is difficult to control. The bolt ball node system often adopts a bulk assembly method, which is assembled on the ground in the form of "one ball and four rods" to form a small unit space node system, and then the adjacent unit space node systems are assembled through rods.

[0004] Because there are many spherical nodes in the steel structure grid system, the spatial position is not easy to control. In addition, if there are position and axial deviations with several adjacent systems, or the processing dimensions of the rods are not accurate, the rigid rods are not easy to assemble with the surrounding spherical nodes. During splicing, the rods may not be aligned with the holes, the rods may be misplaced, and the rods may not be tightened. This will affect the overall quality and safety performance of the grid, and is not conducive to precision control. Utility Model Content
