Embodiment Construction
[0017] The present invention will be described in detail below in combination with specific examples.
[0018] A method for processing a reinforcement cage, comprising the following steps carried out in sequence:
[0019] Step 1. Process the mold pedestal. The base is made of ordinary channel steel. Column A and column B are both made of ∠100. A column is directly welded to the horizontal channel steel of the base. Behind the A column, ∠75 is used to weld with the horizontal channel steel of the base. B The column is pinned to the channel steel at the bottom to make the B column move so that it can rotate 180° on the cross section;
[0020] Step 2. Weld steel bars on A and B columns, process a certain amount of positioning steel bars, and then use more than 20 round steel to process transverse tie rod C, weld sleeves on A and B columns, so that the transverse tie rods can be directly inserted into the sleeves, make it a whole;
[0021] Step 3. Penetrate the steel bars, place...

Abstract
The invention relates to a method for machining a steel reinforcement cage. The method comprises the following sequentially-conducted steps that firstly, a die table base is machined, ordinary box iron is adopted in the base, the angle of 100 degrees is adopted in each of a stand column A and a stand column B, the stand column A is directly welded to base transverse box iron, the back of the column A is welded to the base transverse box iron through the angle of 75 degrees, the stand column B is in pin joint with bottom box iron, and the stand column B is made to move and can rotate on the cross section by 180 degrees; secondly, steel bars are welded to the stand column A and the stand column B, a certain number of positioning steel bars are machined, 20 or more round steel is used for machining a transverse pull rod C, a sleeve is welded to each of the stand column A and the stand column B, the transverse pull rod is directly inserted in the sleeve, and integration is achieved. Time and labor are saved, efficiency is higher, and the quality of the steel reinforcement cage is better.
Description
technical field [0001] The invention relates to a method for processing a reinforcement cage, which belongs to the technical field of building construction. Background technique [0002] With the development of high-speed railways, in order to reduce the post-construction settlement of the line, most of the passenger trains and high-speed railways use bridges instead of roads, and most of them use bored pile foundations. There are 64,054 bored piles in the Beijing-Shanghai high-speed railway alone. The diameters of the piles are mainly 1m, 1.25m and 1.5m. Complete the construction tasks quickly, accurately and with high quality. According to the past experience in processing steel cages, the on-site mold method for processing steel cages is designed. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method for processing steel cages, which saves time and labor and greatly improves the processing quality. ...
