Description

Technical Field

[0001] The utility model relates to the technical field of spherical steel grid structures, in particular to a tool for measuring the ball diameter of a steel structure welding ball. Background Art

[0002] In steel structure engineering, spherical grid is a common structural form, widely used in various buildings and facilities, such as stadiums, exhibition centers, etc. The diameter and size of the welded spherical grid are often distinguished and confirmed by the manufacturer by spraying words on the sphere. During transportation and on-site unloading and stacking, the sprayed specifications are often blurred by bumps or paint peeling and cannot be confirmed. Some spheres do not even have their specifications sprayed on. It is often time-consuming and laborious to find the appropriate specifications of the sphere during on-site supervision, acceptance and installation. Once the error is made, it will affect the overall bearing capacity and stability of the steel structure. Therefore, accurate measurement of the sphere diameter of the grid is one of the important means to ensure the safety and stability of the structure. Utility Model Content
