Construction method of pre-embedded anti-collision steel angles and construction method of reinforced concrete columns

Abstract

The invention discloses a construction method of pre-embedded anti-collision steel angles and a construction method of reinforced concrete columns, and belongs to the technical field of building construction. The construction method of the pre-embedded anti-collision steel angles comprises the steps that the steel angles are cut, anchor bars are welded, and the steel angles are pre-embedded, whenthe steel angles are cut, the length of the steel angles is longer than the preset lengtht, the steel angles are arranged at a certain height of a hooping frame because of anti-collision; when weldingthe anchor bars, the anchor bars are welded to the inner openings of the steel angles, the anchor bars are welded to the steel angles and the strength of the steel angles can be enhanced; when the steel angles are pre-embedded, the steel angles are attached to seam edges of the hooping frame in the vertical direction from the bottom end of the hooping frame, the anchor bars are welded to hooping,a plurality of horizontal binding bars are arranged between the steel angles, the arrangement of the horizontal binding bars can increase the strength of the whole hooping frame. The pre-embedded steel angles on the outer side edges of the hooping frame is simple in construction and one-time forming is achieved, and the problem of surface impression quality of the edges of steel angles due to external reasons such as temperature does not appear.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of pre-buried anti-collision angle steel and a construction method of reinforced concrete columns. Background technique [0002] In the production activities in the area without walls of industrial plants, the corners of reinforced concrete columns are often damaged during the operation of large-scale equipment and tools. Once the corners of reinforced concrete columns are damaged, it is difficult to recover, and the post-processing is troublesome, and the treatment effect is not good. ideal. [0003] At present, most reinforced concrete columns use traditional rubber anti-collision strips for hemming, and the hemming of rubber anti-collision strips is installed after the finished reinforced concrete columns are poured with expansion tube fastening screws, but during the installation process When the expansion bolts are driven into the concret...

Problems solved by technology

[0004] One of the objectives of the present invention is to provide a construction method for pre-embedded anti-collision angle steel and a construction method for reinforced concrete columns, so as to solve the problem that the installation of rubber anti-collision strips in the prior art after the concrete frame columns are formed is likely to cause damage to the surface of the column body, and the rubber strips Affected by temperature, it is easy to deform, and it is a troublesome technical problem to repair later
