Description

Technical Field

[0001] The utility model relates to the technical field of construction tools, in particular to a steel bar positioning structure for building construction. Background Technique

[0002] Steel bars refer to steel materials used for reinforced concrete and prestressed reinforced concrete. Their cross-sections are circular, and sometimes square with rounded corners. It includes plain round bars, ribbed bars, and twisted bars. Steel bars for reinforced concrete refer to straight or coiled steel bars used for reinforcing concrete. Their shapes are divided into plain round bars and deformed bars, and the delivery states are straight bars and coils.

[0003] In civil engineering projects, most building constructions require the use of steel bars, and the steel bars are poured with concrete. After the concrete solidifies, the structure composed of steel bars and concrete can support the building. Before pouring the concrete, it is necessary to tie the steel bars first to ensure that multiple steel bars are evenly distributed. At this time, a positioning device is required. When some existing positioning devices position the steel bars, they cannot well adjust the control range of the positioning device, which easily causes misalignment between the positioning device and the steel bars or the phenomenon that the steel bars cannot be restricted, and thus cannot be well positioned.

[0004] After retrieval, a steel bar positioning structure for building construction is disclosed in the publication number: CN220080828U, which relates to the technical field of construction tools. The steel bar positioning structure for building construction includes a positioning ring. A circular slideway is opened on the surface of the positioning ring. A moving seat is slidably connected inside the circular slideway. A sliding hole is opened inside the moving seat. A sliding rod is slidably connected inside the sliding hole. A limiting plate is fixedly installed on one side of the sliding rod. In this steel bar positioning structure for building construction, when not pulling the sliding rod, the sliding rod and the clamping rod are reset by the pulling force of the tension spring, and then the clamping rod is clamped into the inside of another fixing hole to complete the adjustment of the position of the limiting plate, which is convenient for adjusting the position of the limiting plate, and thus convenient for adjusting the position of the limiting plate according to the position of the steel bar, and further convenient for expanding the use range of the device, preventing deviation between the steel bar and the limiting plate during the positioning of the steel bar, resulting in inability to position.

[0005] When the device in the above application controls the deviation of the steel bar through the semi-circular limiting plate, it cannot prevent the steel bar from shifting outwards. The control range of the moving seat and the sliding rod in the device is small, resulting in limited use scenarios of the device. Utility Model Content

The hexagonal nut 9 is fixedly connected to the rotating column 13, the rotating column 13 is fixedly connected to the gear 14, and the rotating column 13 is rotatably connected to the lower annular slider 5. Therefore, the hexagonal nut 9 and the rotating column 13 drive the gear 14 to rotate. The tooth groove 15 on the moving block 10 is driven by the gear 14 to move back and forth. The sliding plate 21 provides a moving chute 20 for the square slider 19. The support column 18 provides fixation for the moving block 10, the square slider 19 and the sliding plate 21, improving the stability of the moving block 10 and the sliding plate 21. The circular card slot 17 opened on the fixed block 11 and the installed U-shaped buckle 16 control the steel bars in the horizontal direction.

For example, for four steel bars, only one layer is needed; for eight steel bars, two layers are needed; for twelve steel bars, three layers are needed. After determining the number of layers of the device, rotate the hexagonal nut 9 to adjust the length of the moving block 10. After determining the length, press the hexagonal nut 9 to install it in the hexagonal card slot 8. The height of the gear 14 is half of that of the tooth groove 15. Therefore, when the hexagonal nut 9 falls into the hexagonal card slot 8, the position of the gear 14 in the tooth groove 15 changes from the upper part to the lower part. The circular card slot 17 between the fixed block 11 and the U-shaped buckle 16 serves to control the steel bars. The circular space in the middle of the device serves to provide a space for the concrete pipe to pass through during pouring.
