Y-shaped structure construction bracket structure capable of adjusting inclined leg stress in real time

Abstract

The invention discloses a Y-shaped structure construction bracket structure capable of adjusting inclined leg stress in real time. The structure comprises a Y-shaped inclined leg, a supporting deviceand a jacking device; the supporting device comprises a Bailey beam and a plurality of first steel pipe piers, the bottom end of each first steel pipe pier is directly buried in the ground, the top end of each first steel pipe pier is fixedly connected with the Bailey beam respectively, the longitudinal root of the Y-shaped inclined leg is directly buried in the ground, a construction platform isestablished on the supporting device formed by the first steel pipe piers and the Bailey beam, and the construction platform is located above the Y-shaped inclined leg. The Y-shaped structure construction bracket structure is combined with a first steel pipe pier Bailey beam bracket system to achieve the combination of a traditional bracket system and a temporary horizontal pull rod process in theY-shaped structure construction, thereby filling a blank of the bridge structure technology, and therefore the problems are solved that stress of the Y-shaped structure is not facilitated when a bridge bracket is constructed, and a Y-shaped large cantilever sate inclined leg root easily cracks due to larger stress.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a Y-structure construction support structure that can adjust the stress of inclined legs in real time. Background technique [0002] With the rapid development of highway construction in our country, the requirements for the overall performance of the bridge structure are getting higher and higher, such as linear requirements, beautiful appearance requirements, smooth and comfortable driving requirements, etc. In municipal bridges and double-track viaducts, continuous rigid frame bridges with "Y" piers are a more commonly used structural form. The pier makes full use of the space on both sides, so that the span of the main beam can be reduced, which is beneficial to the vertical force of the structure. However, Y-shaped piers have higher requirements for construction technology than traditional vertical piers. Therefore, the construction-related technologies of Y-shaped pie...

AI Technical Summary

Problems solved by technology

However, when the 0# block on the Y pier is being constructed, the construction support is directly supported on the Y structure, and a huge supporting reaction force is generated on the Y structure when the 0# block concrete is poured, so that the oblique legs of the Y structure are at this stage of construction. Extremely unfavorable stress

Coupled with the lack of systematic research and application, the adaptability, technicality, safety and economics of the Y-frame bracket have not yet been clearly answered, the technical application is in an isolated state, and the technical development has not been reported.
