Abstract

The invention relates to the construction of reinforced concrete columns, in particular to edge-protecting angle iron of reinforced concrete columns. A method for installing edge-protecting angle iron of reinforced concrete columns comprises the following steps: flicking concrete-column casing ink lines at floor terraces; setting up an operation scaffold; binding concrete columns with reinforcingsteel bars; utilizing a line hammer to throw the bottom ink lines onto a cross bar of the scaffold; allowing the edge-protecting angle iron to be basically in place according to the ink lines; utilizing a running rule to adjust the angle iron on the bottoms of the columns to be precisely in place; utilizing the line hammer and fixtures to gradually adjust from the bottom up and using the reinforcing steel bars for fixation; pasting foam strips on the sides of the edge-protecting angle iron; and installing templates. The method has the advantages of defining main points of each step of installing the edge-protecting angle iron of reinforced concrete columns, meeting the installation precision of the edge-protecting angle iron, controlling template installation and basically overcoming common quality defects of the installation of the edge-protecting angle iron.

Description

technical field [0001] The invention relates to reinforced concrete column construction, in particular to reinforced concrete column edge protection angle steel. Background technique [0002] In industrial buildings, there are a large number of exposed concrete buildings. In order to prevent the concrete edges and corners from falling due to collisions during the production process and affect the appearance, the design often considers setting up edge protection angle steel to protect the edges and corners. But for a long time, the installation of edge protection angle steel (especially the edge protection angle steel of reinforced concrete columns) always has defects such as cross-sectional dimension out-of-tolerance, distortion, and depression. Contents of the invention [0003] The present invention aims to solve the above-mentioned defects of the prior art, and provides a method for installing reinforced concrete column edge protection angle steel. The invention clari...
