Description

Technical field:

[0001] The utility model belongs to the field of road and bridge construction, and particularly relates to a pile foundation steel cage assembly positioning frame. Background technology:

[0002] The main function of the steel cage is the same as the stress of the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It plays a restraining role on the pile concrete so that it can withstand a certain axial tension.

[0003] The steel cage is mainly welded by long longitudinal bars and circular stirrups. During its production process, multiple longitudinal bars need to be wrapped around and welded to the outside of the circular stirrups. In the existing production process, the welding points are usually determined by drawing marking lines on the surface of the circular stirrups, and then the longitudinal bars are welded to the circular stirrups along the marked welding points. This assembly operation is not only time-consuming and labor-intensive, but also difficult to accurately position the circular stirrups and longitudinal bars during the welding process. In addition, there are often errors in manually drawing marking lines, which leads to the longitudinal bars easily running off course during welding, large welding errors, and poor stress resistance of the welded steel cage, which affects the construction quality of road and bridge construction. Utility model content:

[0004] The utility model aims to provide a pile foundation reinforcement cage assembly positioning frame, and overcomes the shortcomings of the above-mentioned prior art, and effectively solves the existing problem of inaccurate positioning of longitudinal reinforcement and stirrups during the reinforcement cage assembly process.

[0006] Furthermore, a plurality of grooves are evenly formed on the semicircular support plate, and magnet blocks are installed in the grooves.

[0007] Furthermore, two ends of the lower positioning tire frame are fixedly connected with two ends of the upper positioning tire frame by bolts.

[0008] Furthermore, support clamps are vertically mounted on both end side walls of the lower positioning tire frame.

[0009] Furthermore, the base support assembly includes a transverse plate, the lower positioning tire frame is fixedly installed on the top wall of the transverse plate, support columns are installed on the bottom walls at both ends of the transverse plate, the bottom ends of the support columns are fixedly connected to the top wall of the supporting cross bar, and supporting longitudinal bars are fixedly installed at both ends of the supporting cross bar.

[0010] Furthermore, first reinforcing ribs matching the lower positioning tire frame are installed on the top walls at both ends of the transverse plate.

[0011] Furthermore, a second reinforcing rib is installed between the support column and the support cross bar.

[0012] Furthermore, the support columns and the support longitudinal bars are both channel steels, and the support cross bars are I-beams.

[0013] The beneficial effects of the utility model are as follows: by placing the circular stirrups on the semicircular support plate and the longitudinal reinforcement on the lower positioning frame and the upper positioning frame, the circular stirrups and the longitudinal reinforcement can be quickly and accurately positioned and welded, avoiding the deviation of the longitudinal reinforcement during the welding process, saving time and effort, and ensuring the assembly quality of the steel cage.
