Problems solved by technology

This process is simple to operate, saves labor costs, and can shorten the construction period. However, for a steel cage with a large volume and weight, directly setting a lifting point on the single-ring stirrup of the steel cage will easily damage the welding between the main reinforcement and the stirrup, and it is difficult to ensure The overall stability of the pier column reinforcement cage

Embodiment approach

[0065] As a kind of embodiment of the present invention, the process of setting up scaffolding is:

[0066] The first step is to support the adjustable base 16 of the vertical pole on the mountain stone 20, and then set up the first floor vertical pole 17 on the adjustable base 16;

[0067] In the second step, the first floor horizontal bar 18 is set up between the first floor vertical bars 17;

[0068] In the third step, a diagonal brace 19 is set up between the vertical pole 17 on the first floor and the horizontal pole 18 on the first floor to form a basic frame unit;

[0069] In the fourth step, based on the basic frame unit, repeat the first step to bind the next layer of vertical rods on the upper layer of vertical rods 17, and then repeat the second - third steps to expand and build the overall bracket system.

[0070] Step 10. Use ink lines to pop up the pouring elevation position lines around the inner wall of each pier column formwork to facilitate elevation control...

Abstract

The invention discloses an integral hoisting construction method for a pier column reinforcement cage. The method comprises the following steps: manufacturing the pier column reinforcement cage and a reinforcement cage positioning support on the background; erecting a bearing platform template; measuring and setting out the position of the pier stud reinforcement cage; binding bearing platform reinforcing steel bars; installing the pier stud reinforcement cage pre-embedded positioning support; after the positioning support is mounted, fixedly connecting the hoisting pier stud reinforcement cage with the positioning support, and fixing by a wind rope; pouring bearing platform concrete; after the bearing platform concrete reaches the designed strength, dismounting the bearing platform formwork and the pier stud reinforcement cage fixing wind rope; hoisting a pier stud formwork, and fixing the pier stud formwork by using a wind rope; and pouring pier stud concrete. When the method is used for pier column construction, the construction progress is obviously improved.

Description

technical field [0001] The invention relates to a hoisting method for bridge pier columns, in particular to a method in which pier column steel bars are mechanically formed into a cage at the background and integrally hoisted and pre-embedded on site. Background technique [0002] With the development of traffic and road construction, more and more viaducts require the construction of large-scale piers. Such large-scale piers generally adopt steel skeletons bound by steel structures, and then pour concrete. Since the steel bars in the steel bar frame need to realize the vertical butt joint, in order to meet the strength requirements of the steel bar frame. In the construction process of the traditional reinforced concrete inner skeleton, it is necessary to prefabricate the overall reinforced skeleton according to the setting structure of the pre-embedded steel in the concrete. For large bridge piers, the overall height and structure are relatively large, and it is necessary...
