Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] The present invention proposes a method and device for rapid reinforcement of damaged columns. The reinforcement device used in this method—the prefabricated parts can be prefabricated in advance in the factory, and the prefabricated parts only need to be spliced ​​and then anchored to the column during on-site construction. As a whole, the damaged column can be quickly reinforced, and the seismic performance of the reinforced column can be effectively repaired. The specific implementation steps are as follows:

[0029] 1) The prefabricated construction steps of the trough-shaped prefabricated parts will be introduced in detail below;

[0030] 2) Make a groove mold, and the mold size selects the column size commonly used in engineering;

[0031] 3) The mold is accurately laid flat, and three positioning bars are arranged along the heigh...

Abstract

The invention discloses a method and device for reinforcing a damaged RC column rapidly via a prefabricated parts. The prefabricated parts (1), an anchor bolt (2), a post-cast strip (3) and a contraction-free high-strength seam pouring material (4) are included, and each prefabricated part is composed of a pre-buried groove type steel plate hoop, a pre-buried wire mesh sheet and self-compact concrete. According to the reinforcing method, concrete is removed from a damaged protective layer, the prefabricated parts are installed on the reinforced column via the anchor bolt, the right and left prefabricated parts are overlapped with each other and connected to the post-cast strip after welding, joint seams are reinforced, and the reinforced column is more integral. The contraction-free high-strength seam pouring material is used to bind the prefabricated part with a core concrete area of the column, and the column whose performance is improved after reinforcement is obtained. All prefabricated parts can be produced in a factory and assembled and connected onsite, wet work onsite is reduced substantially, the reinforcing efficiency is improved, and the damaged column can be reinforcedrapidly after shocking.

Description

technical field [0001] The invention relates to the technical field of building structure reinforcement, and relates to a rapid reinforcement method, in particular to a method and device for rapid reinforcement of damaged RC columns by using prefabricated components. Background technique [0002] A large number of reinforced concrete structures in service often need to be repaired and strengthened due to various reasons, such as design errors, construction defects, changes in use functions, earthquake disasters, and corrosive environmental impacts. Traditional structural reinforcement methods have disadvantages such as large amount of wet work on site, long construction period, and difficult control of construction quality, while fiber reinforced composite materials also have shortcomings, such as easy peeling under force, reinforcement effect and structural adhesive. Performance is closely related, poor fire resistance and so on. The present invention attempts to propose a...
