[0027] As Figure 1 and Figure 2 shown, the ring beam steel bar binding device of this embodiment is used for pre-assembling the ring beam on the ground. The ring beam includes bottom steel bars, top steel bars, multiple layers of waist steel bars arranged between the bottom steel bars and the top steel bars, and beam longitudinal steel bars. The beam longitudinal steel bars enclose and connect the bottom steel bars, top steel bars, and waist steel bars to form an annular column structure.

The ring beam steel bar binding device includes a positioning mechanism 100 for positioning the bottom steel bars of the ring beam on the ground and a supporting mechanism 200 for vertically and horizontally supporting the ring beam steel bars. Specifically, the positioning mechanism 100 includes a first positioning frame 101 and a second positioning frame 102. The shape of the first positioning frame 101 is adapted to the shape of the bottom steel bars of the ring beam, so that the steel bars of the bottom steel bars of the ring beam can be bent according to the contour of the first positioning frame 101 to realize the positioning of the contour of the bottom steel bars of the ring beam. The second positioning frame 102 is arranged along the circumference of the first positioning frame 101 and fixedly connected to the first positioning frame 101. The width of the second positioning frame 102 is adapted to the width of the bottom steel bars of the ring beam, and is used to position the width of the bottom steel bars of the ring beam by clamping the outer ring steel bars and inner ring steel bars of the bottom steel bars of the ring beam. The supporting mechanism 200 includes a vertical support frame 201 and a horizontal support rod 202. The vertical support frame 201 is arranged vertically and fixedly connected to the positioning mechanism 100, and is used to sequentially penetrate through the top steel bars, waist steel bars, and bottom steel bars of the ring beam to provide vertical support for the interior of the ring beam to prevent it from tipping sideways. The horizontal support rod 202 is movably installed on the vertical support frame 201 in the horizontal direction, and its height is adapted to the height of the waist steel bars and the top steel bars, and is used to be arranged below the waist steel bars and the top steel bars to provide horizontal support for them, so as to facilitate the positioning and binding of the waist steel bars and the top steel bars. Preferably, the length of the horizontal support rod 202 is adapted to the width of the ring beam to be assembled.

[0028] Set out lines on the fabrication site according to the design drawings of the ring beam, and loft the inner and outer contours of the ring beam to be assembled. Position the first positioning frame 101 according to the lofted inner and outer contours of the ring beam and fix it on the fabrication site. Then, fix the second positioning frame 102 on the first positioning frame 101 between the inner and outer contours of the ring beam, and install the support mechanism 200. After completing the installation and positioning of the device, start the pre-assembly of the ring beam: Take two steel bars and respectively clamp them in the second positioning frame 102, make the distance between the two steel bars match the width of the ring beam to be assembled, and bend them along the contour of the first positioning frame 101 for one week and enclose and fix them to respectively form the inner ring beam and the outer ring beam of the bottom reinforcement of the ring beam. Then, take two more steel bars and place them on the horizontal support rod 202, and bend them into the same shapes as the inner ring beam and the outer ring beam respectively to form the inner ring waist reinforcement and the outer ring waist reinforcement. Repeat the assembly steps of the inner ring waist reinforcement and the outer ring waist reinforcement to form multiple layers of waist reinforcement. After the waist reinforcement assembly is completed, take two steel bars and place them on the horizontal support rod 202 above the waist reinforcement and bend them into the same shapes as the inner ring beam and the outer ring beam respectively to form the inner ring top reinforcement and the outer ring top reinforcement. Finally, wind and hoop the beam longitudinal reinforcement around the outside of the top reinforcement, waist reinforcement and bottom reinforcement in the height direction, and bind and weld the steel bars of the top reinforcement, waist reinforcement and bottom reinforcement to the beam longitudinal reinforcement to complete the pre-assembly of the ring beam. After the ring beam is inspected and accepted, pull out the horizontal support rod 202 to the outside of the ring beam, and the assembled ring beam can be hoisted to the required position by a crane. This device can realize the pre-assembly of the ring beam on the ground, simplifies the binding process of the ring beam steel bars, greatly reduces the construction difficulty of the ring beam, and can position, control the protective layer and strengthen the framework of the ring beam steel bars, effectively improving the binding speed of the ring beam steel bars and ensuring the quality of the ring beam, and is also convenient for on-site inspection of the ring beam quality; compared with the prior art, there is no need to bind the ring beam steel bars on the formwork after the roof formwork construction, and the binding of the ring beam steel bars and the roof formwork can be constructed simultaneously, avoiding the cross-operation of formwork support and steel bar binding, reducing interference, saving on-site labor, accelerating the construction progress and shortening the construction period; when using this device to bind the ring beam steel bars, the formwork support system for the beam and slab has been completed, the formwork support system has high strength, stiffness and good stability, which is conducive to construction operations; at the same time, it can avoid high-altitude operations and has high safety.

Preferably, the spoke steel bars 1012 and the annular positioning ribs 1011 are fixed by spot welding. The shape of the annular positioning ribs 1011 is adapted to the contour of the ring beam.
