A Construction Technology of Prefabricated Water-brushed Stone Concrete Railing

Abstract

The invention provides a construction process of prefabricated stone imitation concrete railings. The specific steps are as follows: the columns, handrails and railings are all molded with silica gel molds, and the reinforcement cages and steel plates are configured to perform pressurized grouting. Integral pouring, the steel plate at the bottom of the column is welded to the steel plate reserved for the sidewalk, the handrail is mechanically connected to the column, and then the hole of the column is sealed with grouting material; As a whole, after the assembly is completed, the gaps and cavities in the joint position are filled with structural glue. Beneficial effects of the present invention: while saving construction time, it solves the engineering limitation of not having on-site pouring, and it is formed by one-time pouring with water-brushed stone material, which can make the surface layer and the structural layer have better adhesion and better durability And combination, more green and environmental protection, quick construction, and make the surface layer have the effect of water-brushed stone surface layer.

Description

technical field [0001] The invention relates to a construction process of prefabricated concrete railings imitating water-brushed stone, and belongs to the technical field of bridge railing construction. Background technique [0002] At present, most of the projects in our country need to use concrete structures. For concrete structures, the deterioration of concrete, whether the surface defects of concrete can be controlled, and whether the durability of concrete can meet the service life are all closely related to the construction technology, construction details and maintenance of concrete at the construction site. [0003] At present, most of the traditional concrete railing construction technology is on-site pouring construction, which is prone to the following problems: improper concrete vibration sequence and method; no maintenance of concrete components; excessive drop or pouring layer thickness during concrete pouring; concrete strength lower than formwork removal s...

Problems solved by technology

[0003] At present, most of the traditional concrete railing construction technology is on-site pouring construction, which is prone to the following problems: improper concrete vibration sequence and method; no maintenance of concrete components; excessive drop or pouring layer thickness during concrete pouring; concrete strength lower than formwork removal strength However, premature removal of formwork; unauthorized handling of concrete quality defects by the construction unit; random addition of water at the construction site; improper pouring management, unreasonable thickness of reinforcement and protective layer; excessive slump required at the construction site; , delayed vibration; a series of non-standard constructions such as the waiting time of concrete at the construction site is too long
