Bridge cast-in-place concrete crash barrier construction device and method thereof

Abstract

The invention discloses a bridge cast-in-place concrete crash barrier construction device. The bridge cast-in-place concrete crash barrier construction device comprises an inner formwork, an outer formwork, inner formwork jacking brackets and outer formwork jacking brackets; each outer formwork jacking bracket comprises a first upright rod and a second upright rod which are in hinged connection with each other; a rotating shaft at a hinged position of each first upright rod and the corresponding second upright rod is fixed with the corresponding outer formwork; a rolling wheel is separately mounted at the bottoms of each first upright rod and each second upright rod; a screw rod is separately arranged on the top ends of each first upright rod and each second upright rod; the screw rods ofeach first upright rod and the corresponding second upright rod are connected through a rotating handle; each inner formwork jacking bracket comprises a bottom bracket and a support frame; road wheelsare arranged below each bottom bracket; a pull rod support is arranged above each inner formwork and each outer formwork; the tops of each inner formwork and the corresponding outer formwork are connected through a top pull rod penetrating through the pull rod support of the inner formwork and the outer formwork, and the bottoms of each inner formwork and the corresponding outer formwork are connected through a split screw rod. The bridge cast-in-place concrete crash barrier construction device provided by the invention is safe and reliable and high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction device and method for cast-in-place concrete anti-collision barriers for bridges. Background technique [0002] In the traditional construction of bridge anti-collision guardrails, the installation and removal of the guardrail formwork requires the use of cranes, but the working radius of the crane is limited, and it needs to be constantly shifted to meet the construction requirements, which greatly reduces the construction efficiency. In addition, the connection between the formwork is generally connected by bolts. When installing the connecting bolts and the tension rods of the outer formwork, the operator needs to work in the air outside the guardrail, and the safety is low. Contents of the invention [0003] The main purpose of the present invention is to provide a safe, reliable and high-efficiency bridge cast-in-place concrete anti-collision gua...

Problems solved by technology

[0002] In the construction of traditional bridge anti-collision barriers, the installation and removal of the guardrail formwork requires the use of cranes, and the working radius of the crane is limited, so it needs to be constantly shifted to meet the construction requirements, which greatly reduces the construction efficiency

In addition, the connection between the formwork is generally connected by bolts. When installing the connecting bolts and pull rods of the outer formwork, the operator needs to work outside the guardrail, which is low in safety.
