Embodiment Construction

[0011] The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0012] figure 1 Reinforcement plans for concrete columns, figure 2 Reinforcement elevation for concrete columns. This embodiment includes prestressed rod 1, steel wire 2, fiber concrete 3, angle steel 5, steel backing plate 6, nut 7, U-shaped hoop 8, and epoxy resin grout 9. Prestressed rods 1 are arranged on the four sides of the concrete column 4, steel wires 2 are wound around the prestressed rods 1, U-shaped hoops 8 fix the prestressed rods 1 on the concrete column 4, and fiber concrete is arranged between the prestressed rods 1 and the steel wires 2 3. The angle steel 5 is set on the top of the column as a tensioning device for the prestressed rod 1. After the prestressed rod 1 is stretched, it is fixed with a nut 7, and a steel backing plate 6 is set between the angle steel 5 and the nut 7. The corners of the concrete column 4 are removed, and the surface ...

Abstract

The invention discloses a construction method for a reinforced concrete column, which is characterized in that: the reinforced concrete column comprises prestressed bars, steel wires, fiber concrete, angle irons, steel plate washers, blind nuts, U-shaped hoops and epoxy resin cement paste, wherein the four side faces of the reinforced concrete column are provided with the prestressed bars, the prestressed bars are wound with the steel wires, the prestressed bars are fixed on the reinforced concrete column by the U-shaped hoop, the fiber concrete is arranged between the prestressed bars and the steel wires, the top of the reinforced concrete column is provided with the angle irons serving as a prestressed-bar tension device, the prestressed bars after tension are fixed by the blind nuts, and the steel plate washers are arranged between the angle irons and the blind nuts; the edges and corners at the four corners of the reinforced concrete column are removed, and the surface of the reinforced concrete column is subjected to roughing; and the peripheries of the prestressed bars and the steel wires are sealed by the epoxy resin cement paste. The construction method for a reinforced concrete column is safe, reliable and strong in practicability.

Description

technical field [0001] The invention relates to a structure and a construction method of a reinforced concrete column, which is suitable for the construction field. Background technique [0002] When the strength of the concrete column cannot meet the requirements, it must be reinforced. The method of adding prestressed rods can be used to reinforce the concrete column, and the prestressed rods are forced to bear force by means of prestressing, which avoids the unique stress-strain hysteresis phenomenon in the reinforced structure. , so that the post-added part and the original concrete column can work together better, and the bearing capacity of the concrete can be significantly improved. Contents of the invention [0003] The technical problem solved by the present invention is to provide a structure and construction method of a reinforced concrete column to solve the problem of stress-strain lag in the reinforced structure of the concrete column. [0004] The invention...
