Bridge formwork applied to highway construction

Abstract

The invention belongs to the technical field of bridge construction engineering and relates to a bridge formwork applied to highway construction. The bridge formwork comprises a bridge formwork body and a separation mechanism assembly; the bridge formwork body is connected with the separation mechanism assembly through two sets of connecting cavities; first reset springs, second reset springs, positioning columns and limiting plates are arranged on the inner walls of the connecting cavities; the separation mechanism assembly comprises a base, a working arm and an adsorption seat, the working arm is connected with the base through a first hydraulic oil cylinder, the adsorption seat is connected with the base through a second hydraulic oil cylinder, and the second hydraulic oil cylinder is provided with a negative pressure pump; the positioning columns enters the channel of the working arm, so that a first connection relation can be formed between the bridge formwork body and the separation mechanism assembly; the adsorption seat is adsorbed on the bridge formwork body, so that a second connection relation is formed between the bridge formwork body and the separation mechanism assembly, so that the separation effect of the bridge formwork body and formed concrete is thorough, a constructor can keep a distance from the bridge formwork body, life safety of the constructor is guaranteed, and the whole construction process is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of bridge construction engineering, in particular to a bridge formwork used in highway construction. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas, or across mountains and poor geology, so that vehicles and pedestrians can pass smoothly. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope protection, bank protection, diversion works, etc. In the process of bridge construction, it is often necessary to pour concrete columns. In the process of pouring concrete columns, bridge ...

AI Technical Summary

Problems solved by technology

After the concrete is poured, the anchor holes on the formwork will be embedded in the concrete, and the adsorption force of the concrete to the formwork will make it very difficult to separate the formwork from the concrete

At present, the commonly used separation method is to use manual multi-point prying and pulling outwards. This is not only time-consuming and labor-intensive, but also prone to accidents at the moment of separation. Repair work, which reduces the efficiency of bridge construction and affects the quality of construction
