Description

Technical Field

[0001] The utility model belongs to the field of building construction, and more specifically, particularly relates to a steel bar bundling and positioning device. Background Art

[0002] Steel bar bundling refers to the weaving, binding, and fixing of multiple groups of steel bars at a building construction site to ensure the connection safety and structural stability between steel bars, and is also a key link to ensure the quality of the later concrete pouring structure and the construction safety of the building. Currently, during the construction operation of column steel bar bundling, a column steel bar positioning frame needs to be used in cooperation to ensure that the column steel bars are in a vertical and stable state during bundling and installation, and to avoid the bending of the steel bar cage structure after the column steel bars are bundled. However, the thickness and arrangement spacing structure of the main column steel bars of different construction pouring columns are very different. The clamping bars and positioning bars of the column steel bar positioning frame are both fixed by welding and are fixedly connected according to the designed structure of the steel bar cage. It can be seen that the structure of the traditional column steel bar positioning frame is rigid and fixed. When the column steel bar positioning frame is removed and reused after positioning, it can only be adapted to the pouring columns with the same arrangement structure, and it cannot effectively bundle and position the column steel bars with different thicknesses and arrangement spacing structures of the main column steel bars, resulting in poor structural versatility and inconvenient construction use.

[0027] As Figures 1-7As shown in the figure, the utility model provides a steel bar bundling and positioning device, including a turning knob 3 and a positioning frame 4; the turning knob 3 is rotatably connected to the outer side surface of the connecting frame 2; the connecting frame 2 is nested on the outer side surface of the frame rod 1; the positioning frame 4 includes a reinforcing bar clamping part 401, an adjusting sleeve 402, an adjusting knob 403, a threaded rod 404, a sliding sleeve 405, a clamping ring 406, a clamping plate 407 and a clamping nut 408; the adjusting knob 403 is welded to the non-threaded surface on the outer side of the threaded rod 404; the number of the clamping plates 407 is two groups, and the clamping plates 407 are welded to the left side surface and the right side surface of the sliding sleeve 405.

[0028] When the utility model adjusts the main reinforcement bundling and positioning device, first, according to the designed width of the columnar steel bar cage, rotate the eight groups of turning knobs 3.

Then, according to the arrangement spacing structure of the column main reinforcements, slide the sliding sleeve 405 of the positioning frame 4 along the frame rod 1 to the corresponding bundling position, insert the clamping ring 406 into the through holes of the clamping plate 407, and then screw the two groups of clamping nuts 408 onto the threaded surface on the outer side surface of the clamping ring 406, so that the frame rod 1 is clamped between the clamping plate 407 and the clamping ring 406, completing the clamping and fixing work of the positioning frame 4 on the frame rod 1.

[0031] In the embodiments of the present disclosure, the number of connecting frames 2 is four groups. Each group of connecting frames 2 is welded and connected by two tubular structures arranged in a crosswise manner. A triangular support block is provided between the two tubular structures of the connecting frame 2.
