US 2019/0153728 A1 · CONCRETE STRUCTURE USING REINFORCING PANEL INCLUDING EMBEDDED REINFORCING GRID AND METHOD OF REPAIRING AND REINFORCING THE SAME

Abstract

Reinforcing panel having high durability, high strength, and high hardness is applied such that a concrete structure may be repaired to have excellent resistance to an external environment and to be structurally excellent. In comparison to existing bonding methods, a concrete structure and a reinforcing panel may be completely attached to each other as a whole using a repairing material with high fluidity as a cement-based material injected into a repair cross section. Part with microcracks is completely filled with repairing cement mortar injected at high pressure. Since reinforcing panel is precast-fabricated in a factory, embossing, intaglio, color, and the like may be easily added to an external surface of the reinforcing panel and an excellent exterior may be provided after repair due to an aesthetic cross section thereof The reinforcing panel fabricated in a factory is applied as to reduce labor costs and construction costs.

Dependent claims

A concrete structure C using a reinforcing panel 100 comprising an embedded reinforcing grid, comprising:

a concrete structure C in which a repair cross section is formed at a deteriorated or damaged part;
a reinforcing grid in which a plurality of reinforcing spacers 121 and a plurality of reinforcing channels 122, at certain intervals, are arranged in a grid shape and a plurality of openings are formed at the reinforcing channels;
a reinforcing panel precast-fabricated in a fabricating place to embed the reinforcing grid therein;
a set anchor which comprises an anchor bolt and an anchor nut and fixes the reinforcing panel to the repair cross section of the concrete structure;
and
a repairing cement mortar injected between the repair cross section of the concrete structure and the reinforcing panel,
wherein the repairing cement mortar is injected into the openings formed at the reinforcing channels to integrate the concrete structure with the reinforcing panel.

4 more elements

A method of repairing and reinforcing a concrete structure using a reinforcing panel, comprising:

(a) checking a repair cross section of a concrete structure, which is deteriorated or damaged;
(b) removing chippings of the repair cross section of the concrete structure and forming a drilled hole for a set anchor;
(c) fastening an anchor bolt of the set anchor through the drilled hole and applying a primer to the repair cross section;
(d) previously applying repairing cement mortar to a reinforcing panel or applying the repairing cement mortar to the repair cross section,
(e) compressing the reinforcing panel, in which a reinforcing grid with reinforcing spacers and the reinforcing channels arranged in a grid shape is embedded, to the repair cross section and injecting the repairing cement mortar into openings of the reinforcing channels of the reinforcing panel;
(f) fixing the reinforcing panel to the repair cross section of the concrete structure by additionally applying a pressure using an anchor nut of the set anchor;
and
(g) completing repair and reinforcement of the concrete structure by cutting and removing an end of the anchor bolt of the set anchor when curing of the repairing cement mortar is completed,
wherein the repairing cement mortar is injected into the openings formed at the reinforcing channels of the reinforcing panel such that the reinforcing panel and the concrete structure are integrated as a whole when the repairing cement mortar is completely cured.
