Embodiment Construction

[0014] Embodiments of the invention:

[0015] First, according to the geometric parameters of the reinforced concrete column 4 and the strength requirements of the load, the specifications and lengths of the angle steel 1, the steel bolt 2, the steel pipe 3 and the nut 5 are designed and determined, and the layout and distance of the upper and lower adjacent steel hoops are determined. On each leg of the angle steel 1, reinforcement bolts 2 and steel pipes 3 are arranged at intervals, so as to form vertically adjacent reinforcement hoops in a staggered arrangement.

[0016] Secondly, make the angle steel assembly, that is, weld the reinforcement bolt 2 on the outer surface of one limb of the angle steel 1, and weld the steel pipe 3 on the outer surface of the other limb, so that the arrangement of the reinforcement bolt 2 and the steel pipe 3 in the length direction of the angle steel 1 is arranged at intervals, That is, the order of arrangement on one limb of the angle steel ...

Abstract

This invention discloses a method for bracing concrete column by angle steer in the architectural engineering, in addition to its structure. The method comprises the following steps: a) making the angle steer assembly, that is, welding steer bar bolt in outboard of one limb of the angle steer, welding steer pipe in the other limb; b) setting up the assembly around the concrete column to be braced, each assembly are connected with each other through the steer bar bolt crossing the steer pipe; c) installing cap nut in the steer bar bolt and screwing up, which makes the nearside of each angle steer sticking to the surface of the concrete column. The structure comprises the angle steer, steer bar bolt and the steer pipe, and along the angle steer, the steer bar bolt and steer pipe are set alternatively, which forms interlace arrangement of the adjacent steer hoop.

Description

Technical field: [0001] The invention relates to a method and structure for reinforcing concrete columns with angled steel in construction engineering. Background technique: [0002] The beam and column components in the building structure must be reinforced due to quality accidents during construction, or the load after technical transformation exceeds the design value, resulting in insufficient strength; for reinforced concrete columns, there are two commonly used reinforcement methods: 1. The four corners of the column are wrapped with angle steel, and the angle steel is connected with hoops for reinforcement; the second is to pour at least 80mm thick reinforced concrete around the column to increase the cross section of the column. This reinforcement method is commonly known as "wearing a cotton jacket". The above-mentioned method 1 is convenient, simple, and low in cost. However, since the inner corner of the angle steel section is a circular arc, it is difficult to fit...
