Abstract

The invention discloses an annular steel plate strengthening device for a reinforced concrete column with a circular cross section. The annular steel plate strengthening device comprises two semicircular steel plates, wherein connecting components are welded to the outer sides of the two side edges of the semicircular steel plates; each connecting component is a steel cuboid member, bolt holes are formed in the connecting components, the two semicircular steel plates are symmetrically buckled to the outer side of a reinforced concrete column to be strengthened, and bolts are used for penetrating through the bolt holes, so that the connecting components of the two semicircular steel plates are connected; the bolts are fastened through nuts, so that the annular steel plate strengthening device for the reinforced concrete column with the circular cross section is formed. According to the annular steel plate strengthening device disclosed by the invention, hooped pulling stress is exerted to the annular steel plates through fastening anchor bolts, so that the annular steel plates exert radial compressive stress on the circular reinforced concrete column, concrete is in a state of being stressed in three directions, and the ultimate compressive strength of the concrete and the compressive carrying capacity of the strengthened members can be effectively improved. The members of the annular steel plate strengthening device disclosed by the invention are machined in a plant, the workload of the construction site is small, and the construction is convenient.

Description

technical field [0001] The invention belongs to the technical field of structural engineering reinforcement, and particularly relates to an annular steel plate reinforcement device for reinforced concrete circular cross-section columns. The annular steel plate reinforcement device is especially suitable for reinforcement of reinforced concrete circular pier columns in bridge engineering. 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. Among them, the method of increasing the section can effectively improve the bearing capacity of the components, but the concrete pouring, vibration and maintenance work must be carried out on site, which is inconvenient for construction, increasing the size of reinforced concrete, reducing the effective use area or passing water under the bridge area; sticking ...
