Forming operating mechanism for steel reinforcement cage with protecting layers and method

Abstract

The invention discloses a forming operating mechanism for a steel reinforcement cage with protecting layers and a method. The operating mechanism comprises a main reinforcement positioning frame usedfor positioning the positions of main reinforcements, multiple stirrup suspension brackets which cooperate with the main reinforcement positioning frame and are used for supporting suspension stirrupsand the multiple protecting layers which are arranged outside the steel reinforcement cage main reinforcements in a sleeving manner in the length direction of the steel reinforcement cage. The methodcomprises the steps of 1 arranging the stirrup suspension brackets, 2 suspending the stirrups, 3 inserting the first-layer main reinforcements, 4 moving the stirrups on the stirrup suspension brackets, 5 taking out the stirrup suspension brackets, 6 fixing the stirrups and the first-layer main reinforcements, 7 positioning and bundling the main reinforcements within the height range of top supporting steel beams, 8 positioning and bundling the remaining main reinforcements and 9 installing the protecting layers. According to the forming operating mechanism for the steel reinforcement cage with the protecting layers and the method, the stirrups can be easily supported and are skillfully matched with the first-layer main reinforcements, the positions of the main reinforcements are positioned through limiting of positioning rods and the stirrups, positioning rod supporting parts are extracted out to enable the positioning rods to fall down, and it is guaranteed that the spacing distanceamong the main reinforcements is invariable through installation of the protecting layers.

[0002] At present, the pile foundation is extremely critical in various construction projects, and the production quality and production efficiency of the pile foundation reinforcement cage are important factors affecting the construction quality and progress of the pile foundation. Composition, the reinforcement cage plays a very important role in the stability of the main project. At the present stage, in the process of on-site production of the reinforcement cage for construction, it is often faced with unreliable spacing between the main reinforcements, complicated position calibration, and large errors. Accurate arrangement is required, which will cause uneven stress and affect the later buildings. At the same time, when arranging the main reinforcement of the reinforcement cage, set the stirrups outside the main reinforcement of the reinforcement cage, and mark the stirrups with chalk on the erected main reinforcement. According to the position line of the marked stirrup, move the set stirrup up, and bind the stirrup and the main bar from top to bottom. Because the main bar is relatively heavy and long, it will make the steel cage The process is very complicated and consumes manpower and material resources, which makes it take too long to make the reinforcement cage, which will affect the construction period; in addition, before the reinforcement cage is poured, it is necessary to install a protective layer between the reinforcement cage and the formwork to protect the reinforcement from directly contacting the hole wall. Corroded, the setting of the protective layer is directly related to the durability of the structure. The existing protective layer uses pads or angle steel, which makes the width control of the protective layer complicated and the effect is not good.
