Main beam side-span closure construction method for bond beam cable-stayed bridge

Abstract

The invention discloses a main beam side-span closure construction method for a bond beam cable-stayed bridge. Suspension splicing installation is not conducted on a side-span tail end beam section. A tail-section steel beam is spliced and constructed through a landing steel pipe support. End cross beam reinforced concrete is constructed through a scaffold. A side-span closure opening is additionally formed between the side-span tail end beam section and a sub-tail end beam section. Through reverse pre-deviation of an end cross beam (including a support top board) and jacking reset of the end cross beam, the problem about matching of a bond beam and a standard bond beam section after the end cross beam is poured is effectively solved.

AI Technical Summary

Benefits of technology

This technology allows for better control over the placement of primary or auxiliary ends during building constructions without affecting their environment's temperature and weather condition. It also simplifies the process of constructing these structures while still allowing them to maintain stability when joined together at different times throughout its lifespan. Additionally, this design makes it easier to manufacture high precision components like those used in bridges.

Problems solved by technology

This patented technical problem addressed in this patents relates to controlling the stability or quality of steel - consistently placed together during casting without causing stress concentration on certain parts like cables. Existing solutions involve either temporarily solidifying ends of the composite beam or integrating them into a single piece called a triplex support frame. However these techniques have limitations when applied over longer periods of time because they require significant labor costs and may result in poorer quality concrete being produced compared to more efficient designs involving multiple forms.
