Bridge prestress cognition practical training teaching device and using method

Abstract

The invention relates to a bridge prestress cognition practical training teaching device. The device comprises a beam body component, a reserved hollow hole channel and a spring steel wire, wherein constructional steel bars are arranged in the beam body component, the reserved hollow hole channel is positioned in the beam body component, and the reserved hollow hole channel is in a catenary line shape with two high ends and a low middle; the spring steel wire comprises a strong spring and an anchoring part, a clamp groove is formed in the middle section of the anchoring part, and the clamp groove and the strong spring are provided with external threads; the spring steel wire penetrates into the reserved hollow hole channel, anchoring parts at the two ends of the spring steel wire extend to the outer sides of a left web plate and a right web plate of the beam body component correspondingly, and the two ends of the spring steel wire are anchored to the two ends of the beam body component through matching of nuts and external threads of the anchoring parts after the spring steel wire is stretched. According to the practical training teaching device, the structure of a beam body and the position and fixation of a reserved hole channel can be truly represented, students can easily master the arrangement and action of prestress, the reserved hole channel and the strand penetrating and tensioning process, and the classroom teaching and post training effects are good.

Description

technical field [0001] The invention belongs to the technical field of teaching training devices, and relates to a bridge prestressed cognitive training teaching device and a method of using the same. Background technique [0002] Prestressing is widely used in all aspects of national economic construction. In modern bridges, most of the concrete simply supported girder bridges, continuous girder bridges, T-shaped rigid frame bridges, and continuous rigid frame bridges use prestressing. Therefore, prestressing It is a widely used and important technology and construction process. [0003] In the current cognitive teaching or practical training of bridge prestressing, the concept of prestressing, the arrangement and function of prestressing, the reserved channels, the process and principle of threading and tensioning all need to be explained. The current teaching method is blackboard writing. , multimedia projection, video teaching, there is no cognition and training teachin...

Problems solved by technology

[0003] In the current cognition teaching or practical teaching of bridge prestressing, the concept of prestressing, the layout and function of prestressing, the reserved tunnel, the process and principle of threading and tensioning all need to be explained. The current teaching method is blackboard writing , multimedia projection, video teaching, there is no cognitive and practical training device that can be assembled and disassembled by hands-on operation, students or trainees do not have the opportunity to operate, it is difficult to understand thoroughly
