DETAILED DESCRIPTION

[0022] The specific embodiments of the utility model are described in detail below in combination with the drawings, so that the person skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in combination with its preferred specific implementation, these implementation is only illustrated, not limit the scope of the utility model.

[0023] Reference Figures 1-5 In an embodiment of the utility model, a beam slab steel bar binding jig frame includes: bracket, outer channel steel 3, supporting plate 4, inner channel steel 5, clamping assembly 6, lower positioning plate 7, upper positioning plate 8 and horizontal rib positioning assembly 9, and the length direction of outer channel steel 3, supporting plate 4, inner channel steel 5, clamping assembly 6, lower positioning plate 7 and upper positioning plate 8 are consistent. The bracket is composed of multiple supporting frames with L-shaped structure and interval distribution, and the supporting frame is welded to be L-shaped structure by stand 1 and bottom support 2. Outer channel steel 3, supporting plate 4 and inner channel steel 5 are laid flat on multiple bottom supports 2 by welding, wherein supporting plate 4 is located between outer channel steel 3 and inner channel steel 5, and inner channel steel 5 is close to stand 1. Positioning grooves are formed on the flanges close to each other on outer channel steel 3 and inner channel steel 5. The clamping assembly 6 is movably arranged on the inner channel steel 5 and is used for positioning beam rib. Lower positioning plate 7 and upper positioning plate 8 are fixed on stand 1 by welding and close to one side of bottom support 2, and lower positioning plate 7 is located on the lower side of upper positioning plate 8. Positioning grooves are formed on lower positioning plate 7 and upper positioning plate 8, and lower positioning plate 7 and upper positioning plate 8 are used for positioning stirrup. Two groups of horizontal rib positioning assembly 9 are arranged on each stand 1 and are distributed in upper and lower positions. The two groups of horizontal rib positioning assembly 9 are located between lower positioning plate 7 and upper positioning plate 8 and are used for positioning horizontal rib.

[0024] The inner channel steel 5 is composed of a web and two flanges. In order to distinguish conveniently, the flange close to the supporting plate 4 is named as the inner flange 51, and a plurality of interval distributed positioning grooves are formed on the inner flange 51. The sliding groove 52 is formed on the web along the length direction of the web, and the sliding groove 52 is close to the inner flange 51.

[0025] The clamping assembly 6 comprises a clamping plate 61, a screw rod 63 and an adjusting nut 64. The clamping plate 61 is slidingly arranged in the sliding groove 52. The clamping plate 61 is provided with clamping grooves which are consistent with the number and opening size of the positioning grooves of the inner flange 51. In the initial state, the clamping grooves and the positioning grooves are one-to-one corresponding and mutually coinciding. The screw rod 63 is fixedly arranged at the right end of the clamping plate 61 and is consistent with the length direction of the clamping plate 61. The right end of the screw rod 63 at least partially extends to the outside of the sliding groove 52. The adjusting nut 64 is sleeved on the screw rod 63 and is threadedly connected with the screw rod 63. The adjusting nut 64 is abutted with the right end of the inner channel steel 5. The adjusting nut 64 is continuously pressed against the inner channel steel 5 by rotating the adjusting nut 64 by a tool such as a wrench. Under the action, the clamping plate 61 is pulled. The clamping grooves on the clamping plate 61 are dislocated with the positioning grooves on the inner flange 51. With the continuous sliding of the clamping plate 61, the overlapping area of the relative position grooves and the positioning grooves is continuously reduced. That is to say, the clamping plate 61 and the inner flange 51 after relative displacement can have a dislocation shearing trend to the steel bar to form clamping. In this way, the steel bar can be fixed. After the adjusting nut 64 is rotated out, the clamping plate 61 can return to the initial position under the action of external force. In addition, it should be noted that the design of dislocation clamping can be compatible with the larger opening size of the positioning grooves on the channel steel. For steel bars of different diameters, the present binding jig can effectively and stably position. Of course, the screw rod 63 is a connecting piece, and the adjusting nut 64 is a driving piece. The two can also be in other forms to achieve the purpose of driving the clamping plate 61 to slide and dislocate the clamping plate 61 and the inner flange 51 to form clamping. The upper end of the clamping plate 61 is flush with the upper end of the inner channel steel 5.

[0026] In one embodiment, the width of the sliding groove 52 is adapted to the thickness of the clamping plate 61. The lower part of the clamping plate 61 is at least partially slidingly arranged in the sliding groove 52. Such limiting can ensure the stability of the clamping plate 61 when sliding and prevent side turning.

The positioning pin 11 is located in the sliding groove 52 and on the left side of the clamping plate 61. When the clamping plate 61 is abutted with the positioning pin 11 under the action of external force, the clamping grooves and the positioning grooves are one-to-one corresponding and mutually coinciding.

[0028] In one embodiment, a plurality of clamping blocks 10 are further arranged on the inner channel steel 5. The plurality of clamping blocks 10 are distributed on the upper side of the sliding groove 52 at intervals. The clamping assembly 6 further comprises a supporting plate 62. The supporting plate 62 is fixedly arranged at the lower rear end of the clamping plate 61 to form an L-shaped structure. The supporting plate 62 is located in the sliding groove 52 and is directly below the clamping blocks 10. It can be considered that the longitudinal projection of the clamping blocks 10 can fall on the supporting plate 62. Under the cooperation of the plurality of clamping blocks 10 and the supporting plate 62, the sliding posture of the clamping plate 61 is more stable. The plurality of clamping blocks 10 can prevent the clamping plate 61 from being locally warped due to improper operation or stress concentration in the clamping plate 61. The clamping blocks 10 are located on the rear side of the clamping plate 61.

[0029] The horizontal rib positioning assembly 9 comprises a horizontal rib positioning frame 91, a limiting plate 92 and two linear bearing seats 93, the body of the horizontal rib positioning frame 91 is composed of a plurality of longitudinally spaced support rods, the limiting plate 92 and the linear bearing seat 93 are both fixed on the stand column 1, the horizontal rib positioning frame 91 is slidably arranged through the limiting plate 92 and the linear bearing seat 93, wherein a plurality of through holes matched with the support rods are formed on the limiting plate 92, the limiting plate 92 can ensure the stable sliding posture of the horizontal rib positioning frame 91, and the sliding direction of the horizontal rib positioning frame 91 is perpendicular to the length direction of the inner channel steel 5. In addition, in the embodiment, the linear bearing seat 93 is used to support the horizontal rib positioning frame 91, so that the horizontal rib positioning frame 91 can realize high-precision stable movement.
