Embodiment

[0023] In this embodiment, the reinforced concrete circular pier column to be reinforced with a radius of 0.6m is used as the reinforcement object, which will be described in further detail below in conjunction with the accompanying drawings:

[0024] (1) if Figure 1-4 As shown, a ring-shaped steel plate reinforcement device is provided, including: two semicircular steel plates 1, and a connecting piece 2 is welded on the outside of the two sides of the semicircular steel plate 1. The connecting piece 2 is a steel cuboid member. There is a bolt hole 6 on the part 2, and two semicircular steel plates 1 are buckled symmetrically on the outer side of the reinforced concrete circular pier 5 to be reinforced, and the bolt 3 is passed through the bolt hole 6 to connect the two semicircular steel plates 1 2 is connected, and the bolt 3 is fastened by the nut 4 to form a ring-shaped steel plate reinforcement device for a reinforced concrete column with a circular section.

Abstract

The invention discloses a method for strengthening a circular reinforced concrete pier column. According to the method, an annular steel plate strengthening device is arranged and comprises two semicircular steel plates, connecting pieces are welded to the outer sides of two side edges of the semicircular steel plates and are cuboid steel components, bolt holes are formed in the connecting pieces, the two semicircular steel plates are symmetrically buckled to the outer side of the circular reinforced concrete pier column to be strengthened, bolts are made to penetrate through the bolt holes to connect the connecting pieces of the two semicircular steel plates, the bolts are fastened through nuts, and thus the annular steel plate strengthening device is formed; after the whole fastening process of the annular steel plate strengthening device is completed, anticorrosive treatment of the device surface is performed, and then strengthening of the circular reinforced concrete pier column is completed. By means of the method, concrete is in a three-direction stress state, and thus the ultimate compressive strength of the concrete and the compressive bearing capacity of the strengthened component can be effectively improved; all used components are machined in a factory, so that the workload in a construction site is small, and construction is convenient.

Description

technical field [0001] The invention belongs to the technical field of structural engineering reinforcement, and in particular relates to a method for reinforcing a reinforced concrete circular pier column. Background technique [0002] The reinforcement methods of reinforced concrete circular columns commonly used in engineering include enlarging section method, pasting carbon fiber cloth method and external bonding steel plate method. The method of enlarging the cross-section can effectively improve the bearing capacity of the components, but the pouring, vibrating and curing of concrete must be carried out on site, which is inconvenient for construction, significantly increases the size of reinforced concrete, and reduces the effective use area or the water passing area under the bridge; The method of pasting carbon fiber cloth can improve the bearing capacity of reinforced concrete, but the increase is small, the maximum is about 10%, and the durability is insufficient. ...
