The integral forming construction method of inter-column tie beam and pier column and the formwork support used

Abstract

The invention discloses an inter-stud straining beam and pier stud overall formation construction method and a mold plate bracket used in the method, belongs to the technical field of road bridge pier stud and inter-stud straining beam construction methods, and aims to provide a construction method that an inter-stud straining beam, an upper pier stud and a lower pier stud are formed as a whole through one time of casting, and a mold plate bracket used in the construction method. According to the technical scheme, the inter-stud straining beam and pier stud overall formation construction method comprises the following steps: 1, mounting pier stud reinforcing steel bars; 2, binding reinforcing steel bars of the inter-stud straining beam, erecting mold plates, and casting concrete; 3, performing one-time mounting of mold plates of the upper pier stud, the lower pier stud and the inter-stud straining beam; 4, performing overall casting of concrete of the upper pier stud, the lower pier stud and the inter-stud straining beam; and 5, disassembling the mold plates of the upper pier stud, the inter-stud straining beam and the lower pier stud, wherein the inter-stud straining beam and the pier studs are wholly formed as the mold plate bracket, upper ends of two inclined support rods are connected in the middle of the bottom surface of the bottom mold of the mold plate of the inter-stud straining beam, lower ends of the two inclined support rods are respectively connected with one pier stud mold plate, and a transverse pull rod is horizontally arranged between two pier stud mold plates.

Description

technical field [0001] The invention discloses a construction method for integrally forming inter-column tie beams and pier columns and a template support used therein, and belongs to the technical field of construction methods for highway bridge pier columns and inter-column tie beams. Background technique [0002] In recent years, with the continuous construction of various grades of highways, highway bridges have also been widely used. At present, in the design of highway bridges, most of the bridge piers with a lower height of less than 30m are designed as column piers, which generally consist of caps (inter-pile tie beams) on pile foundations, column pier bodies, and inter-column tie beams (pier column Higher) and cover beams. The advantage is that it can reduce the weight of the pier body, save masonry materials, is more beautiful, has greater rigidity and strength, and can be used in rivers with drifting objects and drift ice. In the construction of the lower part o...

Problems solved by technology

[0004] 1. The progress of the project is affected;

[0005] 2. Increase in engineering costs;

[0006] 3. The stubble between the upper pier column and the lower pier column is prone to misalignment and slurry leakage

This method also has the same shortcomings as the hoop method
