Continuous beam 0# block support and installing method

Abstract

The invention discloses a continuous beam 0# block support structure. Each side of a pier (1) is provided with two pipe stand columns (2) supported by a concrete bearing table (3); short longitudinal beams (4) are arranged at the top ends of the stand columns (2) in a one-to-one correspondence mode, are connected with the pier, are connected with pre-buried pieces of the pier body (1) in a welded mode and are directly connected with the top ends of the stand columns (2) in a welded mode. Cross beams (5) are arranged above the short longitudinal beams (4) and are fixed through welding pieces on the short longitudinal beams (4), and the lengths of the cross beams (5) equal the width of a bridge surface. A plurality of sets of bent frames (6) are arranged above the cross beams (5), one ends of the inner sides of the bent frames (6) are connected with the pier (1) through pre-buried pieces in a welded mode, and the bent frames are fixed relative to the cross beams (5); a box beam bottom die is placed above the bent frames (6). The support structure can safely and reliably meet stress requirements under any working condition in the construction phase, the construction process is simple, fast and convenient, all key portions are clearly stressed, and checking is facilitated.

Description

technical field [0001] The invention relates to a continuous beam 0# block bracket. Background technique [0002] At present, whether it is a high-speed railway or a highway, there are more and more continuous beam constructions, and the safety and stability of the 0# block support plays a decisive role in the continuous beam construction. At present, the forms of 0# block supports are mostly full hall, triangular brackets with embedded corbels in the pier body, and corbels+steel pipe columns supported on the pre-embedded corbel caps in the pier body. The disadvantage of the full hall support is that it is limited by the height of the pier and the bearing capacity of the foundation. The disadvantages of the other two methods are that it affects the appearance of the concrete of the pier body, and the demolition period is long and difficult. Contents of the invention [0003] The technical problem solved by the present invention is: to provide a continuous beam 0# block su...
