A method for strengthening the formwork of the cast-in-place flower pool type anti-collision wall of an urban overpass

Abstract

The invention discloses a method for reinforcing a cast-in-place framed flower bed type anti-collision wall formwork of an urban overpass, wherein the method is used for the technical field of bridge construction. The method includes the following steps that an inside outer die, an outside outer die, an inner die and end dies are prefabricated; the inside outer die is installed, a top beam in the transverse bridge direction is arranged at the top of the inside outer die, a connecting rod is connected between the inner end of the top beam and a connecting seat on an inside beam body of the inside outer die, a cantilever is formed at the outer end of the top beam and connected with the inner die, the outside outer die is installed, the top of the outside outer die is connected with the cantilever, the bottom of the outside outer die is connected with the beam body, and the end dies are installed; the length of the connecting rod is adjusted to correct the perpendicularity of a formwork system, a pull rod is tensioned and fastened between the inside outer die and the outside outer die after the elevation of the inside outer die, the elevation of the outside outer die and the elevation of the inner die are adjusted; and concrete is poured, and the formwork system is detached after the concrete reaches the die detaching strength. By the adoption of the method, the structural stress is clear, safety and reliability are achieved, reinforcing materials are saved, a construction period is short, operation is easy and convenient, the overall stability is high, and die cracking is unlikely to happen.

Description

technical field [0001] The invention is used in the technical field of bridge construction, and in particular relates to a method for reinforcing a cast-in-place flower pond type anti-collision wall template of an urban overpass. Background technique [0002] The anti-collision wall is an accessory structure of a highway bridge. It is not only an important safety protection, but also its line shape and surface finish directly affect the beauty and quality of the bridge. However, because its structure is often small, it is easy to ignore in thought; the current anti-collision wall design tends to be more and more beautiful in appearance, such as vase type, hanging type, etc., but with the acceleration of the concept of urban landscaping and the pace of implementation, There have also been many attempts in the design of the anti-collision wall of urban overpass bridges. The combination of safety protection function and greening function has formed a new flower pond type anti-c...

AI Technical Summary

Problems solved by technology

The construction of the anti-collision wall generally has the bracket method, the cantilever method, etc., but generally adopts flexible cables, rigid support, and the formwork reinforcement rigidity is not high. beautiful
