Prefabricated assembly type construction method for inter-pier collar beams of highway bridges of various grades

Abstract

The invention discloses a prefabricated assembly type construction method for inter-pier collar beams of highway bridges of various grades. The method comprises the steps of step 1, prefabricating a collar beam (1); step 2, conducting field leveling on an inter-pier collar beam construction area; step 3, constructing a bottom collar beam (6); step 4, constructing a first section of pier column; step 5, chiseling and cleaning the top of an upper section pier column template (4); step 6, measuring and setting out the position of the prefabricated collar beam (1); step (7), prefabricating the prefabricated collar beam (1); step 8, arranging hanging rings (7); step 9, transporting and hoisting the prefabricated collar beam (1); step (10), binding remaining steel bars of the first section of pier column; step (11), mounting the rest templates of the first section of pier column; step (12), pouring and maintaining remaining concrete of the first section of pier column; step (13), removing the upper section pier column template (4); and step (14), performing concrete construction on the second-section pier column and the third-section pier column. The method has the advantages that the safety risk of high-place operation of workers is reduced, the construction period is shortened, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of highway bridge construction, in particular to a prefabricated construction method for tie beams between piers of highway bridges of various grades. Background technique [0002] In recent years, with the continuous construction of various grades of highways, highway bridges have also been widely used. At present, the cast-in-place method is usually used in the construction of the tie beams between the piers of highway bridges. After the concrete construction of the pier columns in the upper section is completed, the hoop method or the piercing rod method is used to support the concrete pouring platform of the pier column tie beams, and then support the formwork, Binding steel bars, pouring pier tie beam concrete. This method has the following disadvantages: [0003] Insufficient 1. Due to the long erection period of the bracket, the progress of the project is affected; [0004] Insufficient 2. Increased construc...
