Double-ear plate mounting device and method for truss rod

Abstract

The present invention discloses a double-ear plate installation device for a truss member and a method thereof. A roadbed box is used to improve the ground bearing capacity. The roadbed box can be quickly installed and can serve as both an installation platform and a road surface. Fixed multi-angle clamping blocks form a clamping assembly to limit the lower portion of the ear plate. The upper portion is limited by an angle verification plate and the angle between the double ear plates is verified. This fully utilizes the assembly site, enabling simultaneous processing and batch production of ear plates at multiple angles. Furthermore, the clamping blocks allow for angle adjustment at any time. Specially designed angle verification plates, tailored to the opening and closing angles of the ear plates, can precisely control the assembly of the ear plates and the truss, facilitating disassembly and assembly. This satisfies the control requirements for the installation accuracy of the ear plates, ensures the processing quality of the ear plates, and improves processing efficiency. The present invention solves the problems of traditional trusses or grid frames, such as being bulky, occupying a large area, and having poor control accuracy.
