The invention relates to a column for jacking construction of a long-span steel structure bridge, including a column and a column foundation. The column is composed of a column body, a crosspiece, a scissors brace, a column head and a column foot. The column includes four column bodies, There are crosspieces connected between the main bodies of the columns; the crosspieces are provided with multiple pieces, and are evenly arranged along the length direction of the main body of the columns; scissors braces are connected between the two adjacent crosspieces up and down; the two ends of the scissors braces They are respectively connected to the main body of the column, and the upper and lower adjacent two scissors braces are arranged in opposite directions; the top of the main body of the column is connected to the column head, and the bottom end is connected to the column foot; the column is fixed by the column foot and the column foundation. Compression, flexural, weather resistance, not easy to damage, high support strength, convenient installation and construction, solves the problem of insufficient bearing capacity of support structures encountered in the jacking construction of long-span steel structure bridges, has a wide range of application values, and is worthy of promotion .
Description
technical field [0001] The invention relates to the field of building construction, in particular to a column for jacking construction of a long-span steel structure bridge. Background technique [0002] Existing long-span steel structure bridge jacking construction must use multiple columns to support the bridge body, and these columns not only bear the weight of the bridge body, the vertical load during construction, but also bear the lateral load. Insufficient carrying capacity in any aspect will lead to accidents. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a column for jacking construction of a long-span steel structure bridge. The problem of insufficient bearing capacity of the support structure encountered in the construction of the bridge top push has a wide range of application value and is worth promoting. [0004] The technical solution adopted by the present invention to solve its technical problems ...
