Action regulation fabricated formwork for U-box combined continuous beam segment cast-in-place

Abstract

The invention discloses an action regulation fabricated formwork for U-box combined continuous beam section cast-in-place. The action regulation fabricated formwork comprises an inner mold, a bottom mold and side dies which are oppositely arranged on the two sides of the continuous beam pouring direction and are detachably connected with the inner mold and the bottom mold correspondingly, whereinthe inner mold comprises a top cross beam, an inner mold hydraulic cylinder and a plurality of groups of oppositely-arranged mold sections, the mold sections and the inner mold hydraulic cylinder arehinged to the bottom of the top cross beam, the output end of the inner mold hydraulic cylinder is hinged to the inner walls of the mold sections, a plurality of linear guide rods for supporting the mold sections are hinged in each group of oppositely-arranged mold sections, the side molds comprise upper side molds and lower side molds, the upper side molds are connected with the lower side moldsin an adjustable mode, the top cross beam is fixedly supported at the tops of the upper side molds, a rail car for adjusting the positioning heights and the horizontal torsion angles of the lower sidemolds is hydraulically supported at the bottoms of the lower side molds, and the two sides of the bottom mold are both fixedly connected with the lower side molds and cooperate with the lower side molds to adjust the supported the horizontal positions and the horizontal twisting angles. The action regulation fabricated formwork is suitable for casting the U-box combined continuous beam with variable section width segments.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a pouring formwork for continuous beams. In particular, the utility model relates to a movable adjustable composite formwork for cast-in-situ U-box combined continuous beam segments. Background technique [0002] This scheme relies on the rail transit Z4 line project in Tianjin Binhai New Area, in which our unit is responsible for the construction of the 10.924km elevated section bridge and three elevated stations. [0003] During the construction process, the segmental beam cast-in-place method is used for construction. In the prior art, the segmental beam cast-in-place method is usually directly used for the girder box of the straight section. The formwork used in this pouring construction can often achieve height adjustment and translation adjustment, but now The pouring formwork in the prior art is difficult to adjust its own position, so as to effectively cast t...
