Heavy-load railway pre-cast T beam overall binding carcass and construction method thereof

Abstract

The invention relates to a heavy-load railway pre-cast T beam overall binding carcass and a construction method thereof. The heavy-load railway pre-cast T beam overall binding mold comprises an inner carcass frame and an outer carcass frame, wherein the inner carcass frame comprises a bottom mold, a belly mold and a top mold; the bottom mold is connected with an embedded part of a welding concrete bottom table in a welding way; and the top mold is welded with the top part of the outer carcass frame. Due to the welding connection between the inner carcass frame and the outer carcass frame, the heavy-load railway pre-cast T beam overall binding carcass has the effects of saving occupation area, saving the utilization of a gantry crane and improving the working efficiency. Due to the adoption of an overall lifting appliance during lifting, the minimization of the overall deformation and the local deformation when a framework of steel reinforcement is lifted can be ensured, and the stability of the overall framework of steel reinforcement is ensured.

Description

1. Technical field [0001] The invention relates to a binding mold, in particular to a heavy-duty railway prefabricated T-beam integral binding mold and a construction method thereof. 2. Background technology [0002] At present, in the prefabricated T-beams of heavy-duty railway girder yards, the bottom plate and web steel bars are mostly bound separately from the top plate steel bars, which are hoisted into the formwork and then connected into a whole. The occupation time on the pedestal is difficult to meet the requirements of the construction code for the integrity and positioning accuracy of the beam structure. 3. Contents of the invention [0003] In order to solve the above defects, the present invention provides a railway prefabricated T-beam integral tying mold that can not only satisfy the integrity of the skeleton structure and the accuracy of positioning control, but also improve the efficiency of steel skeleton binding, and the overall skeleton is not easily de...
