Reinforcement device and method for a prefabricated concrete column

Abstract

The invention discloses an assembled concrete column reinforcement method and a reinforcement device, which belong to the related technical field of reinforced concrete structure reinforcement, including reinforcement slats, prefabricated concrete slabs and outer cladding; Axially cut grooves, and pour structural adhesive into the grooves; insert a part of the reinforcement slats into the grooves; pour structural adhesive into the reserved grooves of the precast concrete slabs, and connect the precast concrete slabs with the concrete columns to be reinforced Structural adhesive is also applied evenly on the surface; the reserved groove of the precast concrete slab is aligned with the reinforcement strip for installation, and the precast concrete slab is attached to the surface of the concrete column to be reinforced; the outer surface of the precast concrete slab is coated with structural adhesive agent and paste multiple layers of outer cladding around its surface. The invention can significantly improve the compressive and bending bearing capacity of the concrete column, does not need complex formwork engineering and large-scale machinery, is convenient in construction, and has broad engineering application prospects.

Description

technical field [0001] The invention belongs to the related technical field of reinforced concrete structure reinforcement, and more specifically relates to an assembled concrete column reinforcement device and a reinforcement method. Background technique [0002] Since my country's reform and opening up, infrastructure construction has experienced decades of rapid development. At the same time, the demand for maintenance, reinforcement, repair, and transformation brought about by the huge infrastructure scale is also increasing, which greatly promotes the development of related structural reinforcement technologies. [0003] Existing reinforcement methods for concrete compression-bending members (columns) mainly include enlarging column cross-section with cast-in-place concrete, outsourcing steel plates or fiber-reinforced polymer (Fiber-Reinforced Polymer, FRP) constraints and other methods. However, these methods have some disadvantages. For example, the method of enlarg...

Problems solved by technology

However, these methods have some disadvantages. For example, the method of enlarging the column section with cast-in-place concrete requires complex formwork engineering and large-scale transportation and pouring equipment, and the construction period is long, and the construction quality is difficult to control; the outsourcing steel plate is facing the problem of steel corrosion; only When FRP constraints are outsourced, the increase in the flexural capacity of the column is extremely limited

[0004] Therefore, there is an urgent need for a more efficient and convenient concrete column reinforcement device and method to solve the inconvenience caused by pouring concrete on site in the reinforcement of concrete columns and the limited improvement of the bending bearing capacity of reinforced concrete columns.
