Embodiment 1

[0028] This embodiment provides a reinforced concrete frame column reinforcement cage, including a grouting sleeve reinforcement cage and a column reinforcement cage, the grouting sleeve reinforcement cage is arranged at the lower part of the column reinforcement cage, and the column reinforcement cage includes an inner longitudinal main reinforcement 1, an outer longitudinal reinforcement cage Main reinforcement 2, octagonal spiral stirrup 3, rectangular stirrup 4 and tie reinforcement 5, one end of the inner longitudinal main reinforcement 1 is fixedly installed on the top of the grouting sleeve reinforcement cage, and the inner longitudinal main reinforcement 1 is set to 8 and is octagonal Arranged, one end of the outer longitudinal main reinforcement 2 is fixedly installed on the top of the grouting sleeve reinforcement cage. The outer layer longitudinal main ribs 2 are set to 4 and distributed in a rectangular shape, the height of the inner layer longitudinal main ribs 1 a...

Embodiment 2

[0030] In this embodiment, the present invention is further explained and illustrated by taking the steel cage required for making a reinforced concrete frame column with a height of 6.3 meters and a width of 2.4 meters as an example. The manufacturing method of this embodiment includes the following steps:

[0031] Step 1. Make 3 units of octagonal spiral stirrups: Cut the original steel bars according to the longitudinal main bars of the required length of the column reinforcement cage on the design drawing, and then put a cut ribbed rebar with equal cross-section on the spiral stirrup forming machine Bending continuously to form an octagonal spiral stirrup;

[0032] Step 2. Piercing the longitudinal main reinforcement of the outer layer 2: Piercing the rectangular stirrup 4 main reinforcement at the four corner holes of the reinforcement cage of the grouting sleeve.

[0033] Step 3. Piercing the longitudinal main reinforcement of the inner layer 1: Piercing the main reinfo...

Abstract

The invention discloses a reinforced concrete frame column steel reinforcement cage and a manufacturing method thereof. The reinforced concrete frame column steel reinforcement cage comprises a lowergrouting sleeve steel reinforcement cage body and an upper stand column steel reinforcement cage body, the inner layer of the upper stand column steel reinforcement cage body is formed by arranging longitudinal main reinforcements into an octagon shape, octagonal spiral stirrups are bound outside the main reinforcements, the outer layers of the octagonal spiral stirrups are formed by arranging longitudinal main reinforcements into a rectangle, and rectangular stirrups are fixed outside the main reinforcements. According to the steel reinforcement cage and the manufacturing method of the steelreinforcement cage, the octagonal stirrup form is adopted, automatic, efficient and high-quality machining of the formed reinforcement framework can be achieved, the section is restrained more effectively through the continuous spiral stirrups, the section bearing capacity is improved, and the overall frame rigidity is improved; and meanwhile, dead weight of the steel reinforcement cage is reduced, the consumption of reinforcing steel bars is saved, the working efficiency is improved, and the engineering quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and in particular relates to a reinforcement cage for a reinforced concrete frame column and a manufacturing method thereof. Background technique [0002] In my country, most high-rise buildings adopt reinforced concrete frame structures, and the frame columns bear all the additional loads caused by vertical loads and horizontal loads. With the vigorous development of prefabricated buildings, the application of prefabricated reinforced concrete frame columns is becoming more and more extensive, and the requirements for the types and models of frame columns are also increasing. The existing reinforced concrete frame columns tend to be single, and it is difficult to meet the load-bearing capacity required by increasingly complex engineering construction, especially difficult to meet the load-bearing capacity of buildings with heavy loads and strict requirements on the foundation. ...
