AI Technical Summary
During the pouring process of structural columns, the longitudinal reinforcement stirrups in the column are prone to break away from the limit position due to sliding of the pad, resulting in exposed ribs and affecting the quality of the project.
A new type of structural column formwork reinforcement positioning device is designed, including a detachable rectangular frame and sleeve. The longitudinal reinforcement stirrups in the column are stably positioned by positioning the reinforcement to prevent them from moving or tilting during the pouring process.
It effectively prevents the longitudinal reinforcement stirrups in the column from moving or tilting during the pouring process, avoids exposed ribs, improves the quality of the project, and is easy to operate and can replace the main corrugated in some formwork systems.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building engineering, and in particular relates to a novel structural column template reinforcement positioning device. Technical Background
[0002] The structural column is cast by building a formwork system. The current formwork system generally includes main ribs, secondary ribs (i.e. wooden squares) and formwork. There are steel cages and some longitudinal stirrups in the formwork. In order to ensure that the steel cages and the longitudinal stirrups in the columns are in the correct position during the casting process, pads are generally set at the longitudinal stirrups in the columns at the four corners, that is, pads of a certain thickness are set between the longitudinal stirrups in the columns and the formwork to prevent the longitudinal stirrups in the columns from being too close to the formwork during the casting process, resulting in quality defects such as exposed reinforcement. However, the pads are easy to slide downward during the casting process and leave the limited use position, resulting in exposed reinforcement on site, affecting the quality of the project. Utility Model Content
[0003] The utility model provides a novel structural column template reinforcement positioning device, which can solve the problems pointed out in the background technology.
[0004] A novel structural column template reinforcement positioning device comprises four connecting frames, which are detachably connected end to end to form a rectangular frame, sleeves are respectively provided at the four corners of the rectangular frame, and positioning steel bars are inserted into the sleeves. The connecting frame is an "L"-shaped frame, and the sleeves are arranged at the inner corners thereof. Both ends of the "L"-shaped frame are provided with connecting chamfers that match each other, and both ends of the "L"-shaped frame are provided with connecting plates with holes.
[0005] Beneficial effects: The utility model provides a novel structural column formwork reinforcement positioning device, which can position and stabilize the longitudinal stirrups in the column by positioning the steel bars, thereby preventing them from moving and tilting during the pouring process, and preventing them from being close to the formwork and exposing the reinforcement, thereby improving the quality of the project. The device is also easy to operate and can also replace the main ribs in the formwork system. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.
[0012] Example 1: Figure 1-3 As shown, the new structural column formwork reinforcement positioning device provided by the embodiment of the utility model includes four connecting frames 11, and the four connecting frames 11 are detachably connected end to end to form a rectangular frame 1. Sleeves 12 are respectively provided at the four corners of the rectangular frame 1, and positioning steel bars 13 are inserted in the sleeves 12. The sleeves 12 play a role in stabilizing and limiting the positioning steel bars 13, and realize the detachable connection between the two.
[0013] Specifically, the connecting frame 11 is an "L"-shaped frame, and a sleeve 12 is provided at the inner corner thereof, and both ends of the "L"-shaped frame are provided with mutually matching connecting chamfered surfaces 14. The connecting chamfered surfaces 14 are provided for easy connection and stable connection, and the connecting chamfered surfaces 14 can be 45-degree chamfered surfaces, and both ends of the "L"-shaped frame are provided with connecting plates 15 with holes, and the four connecting frames 11 are connected end to end in sequence, and the corresponding connecting plates 15 with holes are fastened and connected by bolts.
[0014] The working principle of the utility model is as follows: a template system is supported, that is, a template 2, a wooden square 3 and a rectangular frame 1 are used to replace the main rib. A steel cage and longitudinal stirrups in the column are built in the template 2. One inner end of the positioning steel bar 13 is inserted into the template 2 and welded to the longitudinal stirrups in the column at the four corners. After all the erection is completed, pouring is carried out. After pouring is completed, the four connecting frames 11 are removed. Since the positioning steel bar 13 is inserted into the sleeve 12, the four connecting frames 11 can be easily disassembled. One inner end of the positioning steel bar 13 is partially poured in the lattice column, and the exposed part can be removed.
[0015] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
