Abstract

The invention discloses a self-compacting concrete FRP sleeve reinforcing device and a construction method. A formwork is fixedly arranged on a mounting base, a prefabricated sleeve is arranged on the inner side of the formwork, a column body is sleeved with the prefabricated sleeve, and a filling layer is arranged between the prefabricated sleeve and the column body; the prefabricated sleeve is formed by splicing two semicircular connecting parts, and the fastening strip is arranged on the outer side of the prefabricated sleeve and used for fastening the two connecting parts. According to the device, the uneven surface of the damaged column does not need to be repaired and leveled, early-stage preparation work is reduced, the device is simple in structure and convenient to install, and the construction period is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of construction equipment, and more particularly, to a self-compacting concrete FRP sleeve reinforcement device and a construction method. Background technique [0002] Reinforced concrete column is a new type of high-efficiency composite component developed in recent years. It can give full play to the material properties of both steel and concrete, and has the advantages of high bearing capacity and good seismic performance. It is the most basic load-bearing member in the building, and is often used as the column of the floor, the pier, the foundation column, the tower and the truss. However, the newly poured concrete structure is vulnerable to environmental erosion during use, resulting in erosion damage, which in turn affects the integrity of the structure and reduces its service life. [0003] At present, there are the following reinforcement methods for damaged reinforced concrete columns: ①Replace th...
