Methods of installing, fixing, dismantling and moving the concrete guardrail formwork of viaducts and bridges

Abstract

The invention discloses a device and a method for assembling, fixing, detaching and moving overhead road and bridge concrete guardrail templates and belongs to building engineering. The device comprises an inner template, an outer template, a connecting joint, fixing feet, a supporting pipe, fastening screws, a lifting vehicle and a T-shaped lifting hook, and is characterized in that the connecting joint combines the inner template and the outer template into a whole; the templates are respectively assembled, disassembled and moved by the lifting vehicle at one time; the positions of the templates are fixed by the fixing feet; the supporting pipe and the fastening screws regulate and limit a concrete casting cavity; the templates are stripped under the lever effect of the T-shaped lifting hook. Compared with the prior art, the device and the method have the advantages of simplifying procedures, saving materials, reducing labor intensity and improving working efficiency and engineering quality, and particularly, the suspension operation and construction outside a road and a bridge are not required, and the safety of constructors is facilitated, so that the device and the method have very good popularization and application value.

Description

1. Technical field: [0001] The invention belongs to construction engineering, in particular to a method for installing, fixing, dismantling and moving concrete guardrail templates for viaducts and bridges. 2. Background technology: [0002] High-speed and viaducts account for an increasing proportion of modern land transportation, and cast-in-place concrete guardrails with anti-collision functions on both sides are widely used. In the prior art, there are many unsatisfactory parts in the loading, fixing, dismantling and moving process of cast-in-place concrete guardrail formwork and the equipment used, mainly including: 1. The construction of the concrete guardrail is completed at the main body of the road and bridge deck, and the supporting device After dismantling, the inner and outer templates are installed separately, and unified positioning and fixing are completed. The vertical lifting of the outer formwork is mostly set on the side of the road bridge surface, and the...

Problems solved by technology

These tasks require workers to be carried out in a suspended state on high-altitude road sections that are off the ground, which takes up many people, equipment and appliances, and the work is difficult, high-risk, and low-efficiency

2. After the concrete is finalized and the formwork is removed, it is still necessary to remove the wedges and studs and repair the damaged rough surface in the suspended state, which not only adds a lot of trouble, but also affects the unity and integrity of the project and reduces the project the inner quality of
