Abstract

The invention discloses a support structure for large-span continuous beam construction. The support structure is characterized in that a combined structure combining a steel tube support (which is formed by steel tube columns (2) and longitudinal and transverse connecting rod systems (3)) and a bowl-type full support (7) is adopted on the section striding the expressway; strip foundations (1) are adopted on the lower part; the steel tube columns (2) with diameters phi being 800mm and 600mm are arranged on the strip foundations (1); a bearing beam (4) manufactured with double I40 I steel is arranged on the tops of the steel tube columns (2); Bailey beams (5) vertical to the highway are arranged on the bearing beam (4); I16 I steel (6) is arranged on the Bailey beams (5); the bowl-type full support (7) is arranged on the I steel (6) and is adopted beyond the range of the highway; the longitudinal and transverse connecting rod systems (3) are arranged between the steel tube columns (2); and the Bailey beams (5) are vertical to the highway. The support has high cyclic utilization rate, is convenient to mount and dismount, is fast in construction and is low in cost.

Description

technical field [0001] The invention relates to a large-span continuous beam construction support structure. Background technique [0002] At present, the design of large-span continuous beams in railway construction generally adopts the method of hanging blue hanging irrigation. Even if the support is cast-in-situ, it is also the cast-in-situ construction of the whole-hole simply supported beam support. This kind of construction speed is slow and often affects the construction period. Now entering the era of rapid development, the use of cast-in-place construction of large-segment supports is a development trend to increase construction speed and shorten construction period. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large-span continuous beam construction support structure to overcome the shortcomings of the existing technology, such as slow construction speed and often affecting the construction period....
