Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a main reinforcement positioning device for a reinforcement cage. Background Art

[0002] With the development of the construction industry, the height of buildings is increasing, and the requirements for the bearing capacity of the foundation are constantly increasing. When bored piles are used as pile foundations, the length of the bored piles is constantly increasing, resulting in the continuous increase in the length of the steel cage. Longer steel cages are usually made in sections. In order to ensure that the main bars of the upper and lower steel cages correspond, the main bar positioning requirements of the steel cage are relatively high. In the prior art, when processing a longer steel cage, it is necessary to complete the processing of the first section of the steel cage, and then align the main bars of the second section of the steel cage with the main bars of the first section of the steel cage, tighten the mechanical connection joints, and then process the second section of the steel cage. The processing occupies a large area and the installation is labor-intensive and time-consuming. According to the design requirements, when two adjacent sections of the steel cage are connected, the main bars located at the same section cannot exceed 50% of the joints or welding points. Therefore, when the steel cage is made, it is necessary to control the extension length of the main bars at the end, which are divided into long-head main bars and short-head main bars, among which the long-head main bars and short-head main bars cross each other. At present, long-head main bars or short-head main bars are generally controlled manually, and the extension length of the main bars is measured by a tape measure, and half of the main bars of the steel cage are controlled to extend a shorter distance, and the other half are controlled to extend a longer distance, and the joints of multiple long-head main bars or multiple short-head main bars are ensured to be flush. This method has a large workload, low work efficiency, large measurement errors, and a relatively long construction period. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a main reinforcement positioning device for a steel cage, which effectively solves the problems of large processing area, low work efficiency and large measurement error, and overcomes the shortcomings of the prior art.

[0004] The technical solution adopted by the utility model is: a main reinforcement positioning device for a steel cage, including a positioning plate, a first positioning cylinder and a second positioning cylinder are provided on one side of the positioning plate, which are used to insert the main reinforcement of the steel cage, the main reinforcement inserted in the first positioning cylinder is set as a short-head main reinforcement, and the main reinforcement inserted in the second positioning cylinder is set as a long-head main reinforcement.

[0005] Furthermore, a blocking plate is provided at one end of the first positioning cylinder close to the short-head main rib, which is used to limit the length of the short-head main rib inserted into the first positioning cylinder.

[0006] Furthermore, a groove is provided at one end of the first positioning cylinder close to the short-head main rib, and the groove is used for inserting the blocking plate.

[0007] Furthermore, the positioning plate is provided with a connecting hole, and the connecting hole can be detachably connected to the wall.

[0008] Furthermore, the length L2 of the second positioning cylinder is 200-500 mm.

[0009] Furthermore, the length of the first positioning cylinder L1=L2+35d, wherein d is the diameter of the main reinforcement of the reinforcement cage.

[0010] Furthermore, the inner diameters φ of the first positioning cylinder and the second positioning cylinder are greater than d1+2h1, wherein d1 is the inner diameter of the main reinforcement of the steel cage, and h1 is the longitudinal rib height of the main reinforcement of the steel cage.
