[0022] The following is combined with Figure 1 -Attached Figure 2 The utility model is described in further detail.

[0023] The embodiment of the utility model discloses a vertical steel bar fixing device for cast-in-situ columns. Figure 1 and Figure 2 The vertical reinforcement fixing device for cast-in-place columns includes a base plate 1, a guide rail 2 fixed to the outer peripheral wall of the base plate 1, and a slider 3 slidably arranged in the guide rail 2.

[0024] Reference Figure 1 and Figure 2The base plate 1 is disc-shaped, and a fastening hole 10 for a bolt to pass through is provided at the center of the base plate 1. Anti-slip grooves are provided on the upper and lower surfaces of the base plate 1 (not shown in the figure); two guide rails 2 are provided and symmetrically fixed to the outer wall of the base plate 1, and the center lines of the two guide rails 2 coincide. The guide rails 2 are rectangular and include a bottom plate 20, a side plate 21 and a baffle 22.

[0025] Reference Figure 1 and Figure 2 , a first sliding hole 200 is opened on the bottom plate 20 along the length direction, and the first sliding hole 200 is a waist-shaped hole; the side plates 21 are vertically fixed to both sides of the bottom plate 20, and a second sliding hole 210 is opened on one of the side plates 21 along the length direction, and the second sliding hole 210 is a waist-shaped hole, and a plurality of limiting holes 211 are evenly opened on the other side plate 21 along the length direction, and the limiting holes 211 can be threadedly connected to the top screw for tightening and fixing the slider 3; the baffle 22 is vertically fixed to the side plate 21, and the side wall of the baffle 22 is provided with mm-level scale lines (not shown in the figure) along the length direction to facilitate the positioning of the slider 3, and a gap is set between the two baffles 22. The width of the gap is consistent with the width of the first sliding hole 200, and the baffle 22, the bottom plate 20 and the side plates 21 cooperate with each other to limit the slider 3 to slide only along the length direction of the guide rail 2.

[0026] Reference Figure 1 and Figure 2 The slider 3 is in the shape of a rectangular block, and a clearance hole 30 is opened in the middle of the slider 3. The gap between the clearance hole 30, the first sliding hole 200 and the two baffles 22 can be used for the passage of steel bars; a positioning hole 31 is opened on the side wall of the slider 3 and is perpendicular to the clearance hole 30. The positioning hole 31 is arranged opposite to the second sliding hole 210. The positioning hole 31 can be threadedly connected to a top screw for tightening and fixing the steel bar. The top screw can be passed through the second sliding hole 210 and slide along the length direction of the second sliding hole 210.

[0027] The implementation principle of the vertical steel bar fixing device for cast-in-situ columns in the embodiment of the utility model is as follows: when in use, the fixing device is installed on the top of the steel bar, and each fixing device can fix two steel bars at the same time. A corresponding number of fixing devices can be set according to the number of steel bars that need to be positioned. Multiple fixing devices can be stacked up and down and adjusted to different angles. Since anti-slip grooves are set between multiple base plates 1, multiple fixing devices can be connected together at the same time by passing bolts through multiple fastening holes 10, thereby effectively fixing the angle of the base plate 1.

[0028] Insert the rebar through the clearance hole 30, move the slider 3 to the set scale, and then screw the top screw into the positioning hole 31 to secure the rebar. This top screw is set as the first fixing part. Screw the top screw into the limit hole 211 to secure the slider 3. This top screw is set as the second fixing part. This completes the positioning of the rebar. This fixing device saves time on-site inspections of the rebar positioning of cast-in-place columns, improves the construction quality and efficiency of prefabricated columns, and reduces construction costs.

[0029] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
