[0018] This application discloses a rebar cage joint positioning and connection device. It uses two limiting members 1 to adjust and limit the position of the main reinforcement bars 31 at the ends of the rebar cages 3, thereby restricting the position of the two limiting members 1 to ensure that the positions of the main reinforcement bars 31 of the two rebar cages 3 correspond one-to-one with the positioning members 2. The two limiting members 1 are respectively located at adjacent ends of the two rebar cages 3. Each limiting member 1 includes: an upper limiting ring 11, sleeved on the outside of the rebar cage 3; multiple upper limiting rods 12, inclinedly arranged on the inner ring of the upper limiting ring 11, with the number of upper limiting rods 12 being the same as the number of main reinforcement bars 31 in the rebar cage 3; and a lower limiting ring 13, sleeved on... Outside the reinforcing cage 3, the lower limiting ring 13 is attached to the upper limiting ring 11; multiple lower limiting rods 14 are inclinedly arranged on the inner ring of the lower limiting ring 13, and are equidistantly spaced along the inner circumference of the lower limiting ring 13. The ends of the lower limiting rods 14 away from the lower limiting ring 13 intersect with the ends of the upper limiting rods 12 away from the upper limiting ring 11 to form a fixing frame 15. The main reinforcing bars 31 are attached to the corresponding positions of the inner sidewall of the fixing frame 15, so that the ends of the multiple main reinforcing bars 31 of the two reinforcing cages 3 correspond one-to-one. To a certain extent, it is not necessary to continuously adjust the position of each main reinforcing bar 31 when connecting the main reinforcing bars 3 of the reinforcing cages 3, which makes it easier to connect the main reinforcing bars 31 of two adjacent reinforcing cages 3 into a whole.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figures 1-5A rebar cage joint positioning and connection device includes two limiting members 1 for adjusting and limiting the position of the main reinforcement bars 31 at the ends of the rebar cage 3, and two positioning members 2 for limiting the position of the two limiting members 1 so that the positions of the main reinforcement bars 31 of the two rebar cages 3 correspond one-to-one. The limiting member 1 includes an upper limiting ring 11, multiple upper limiting rods 12, a lower limiting ring 13, and multiple lower limiting rods 14. The upper limiting ring 11 is sleeved on the outside of the rebar cage 3. The multiple upper limiting rods 12 are inclinedly arranged in the inner circle of the upper limiting ring 11. The multiple upper limiting rods 12 are arranged at equal intervals along the circumference of the inner circle of the upper limiting ring 11. The multiple upper limiting rods 12 are fixedly connected to the inner circle of the upper limiting ring 11. The number of upper limiting rods 12 is the same as the number of main reinforcement bars 31 of the rebar cage 3 and they are spaced apart. Equally, the lower limit ring 13 is sleeved outside the steel cage 3, and the lower limit ring 13 is in contact with the upper limit ring 11. The upper limit ring 11 is located above the lower limit ring 13. Multiple lower limit rods 14 are inclinedly arranged in the inner circle of the lower limit ring 13. The multiple lower limit rods 14 are arranged at equal intervals along the circumference of the inner circle of the lower limit ring 13. The multiple lower limit rods 14 are fixedly connected to the inner circle of the lower limit ring 13. The ends of the lower limit rods 14 away from the lower limit ring 13 intersect with the ends of the upper limit rods 12 away from the upper limit ring 11 to form a fixed frame 15. The main reinforcement 31 is in contact with the corresponding position of the inner side wall of the fixed frame 15. The multiple main reinforcement 31 of the steel cage 3 are inserted into the multiple fixed frames 15 at the corresponding positions to limit the position of the multiple main reinforcement 31.

[0021] Reference Figures 1-5The lower limiting ring 13 includes multiple lower arc-shaped plates 131, with adjacent ends of the multiple lower arc-shaped plates 131 connected by bolts. The upper limiting ring 11 includes multiple upper arc-shaped plates 111, with each upper arc-shaped plate 111 corresponding to one of the multiple lower arc-shaped plates 131. The multiple upper arc-shaped plates 111 are fitted end-to-end. Each end of the upper surface of the upper arc-shaped plate 111 has a limiting hole 16, which extends onto the lower arc-shaped plate 131. A limiting post 17 is movably inserted into the limiting hole 16. In use, the multiple lower arc-shaped plates 131 are first assembled to form the lower limiting ring 13. The lower limiting ring 13 is then fitted onto the end of the reinforcing cage 3. The upper limiting rod 12 of the upper arc-shaped plate 111 is then inserted into the corresponding reinforcing bar. The upper limiting rod 12 is then moved towards the lower limiting rod 14, causing the multiple main reinforcing bars to move. The upper arc plate 111 is then fitted with the corresponding position of the inner side wall of the multiple fixed frames 15, and the lower arc plate 131 is fitted with the corresponding position of the upper arc plate 111. The limiting post 17 is then inserted into the limiting hole 16 of the upper arc plate 111 and extends into the limiting hole 16 of the lower arc plate 131. The remaining lower arc plate 131 is then installed on the upper arc plate 111 at the corresponding position, so that the multiple main bars 31 of the steel cage 3 are fitted with the corresponding positions of the multiple fixed frames 15, thereby limiting the position of the multiple main bars 31. After connecting the two steel cages 3 together, the limiting post 17 is pulled out, and the upper arc plate 111 and the lower arc plate 131 are separated. The upper arc plate 111 is then taken out in sequence, and the lower limiting ring 13 is disassembled into multiple lower arc plates 131 for easy reuse of the limiting component 1.

[0022] Reference Figures 1-3 The positioning component 2 includes multiple connecting blocks 21 and multiple threaded rods 22. Each connecting block 21 corresponds to a position on a lower arc-shaped plate 131, and the connecting blocks 21 are fixedly connected to the center of the convex surface of the lower arc-shaped plate 131. Each threaded rod 22 corresponds to a position on a connecting block 21, and the threaded rod 22 passes through two connecting blocks 21 at corresponding positions on two limiting components 1. The threaded rod 22 is threadedly connected to the corresponding connecting blocks 21. After installing the limiting components 1 at adjacent ends of the two steel cages 3, the position of the steel cages 3 suspended in the air is adjusted. This ensures that the positions of multiple connecting blocks 21 on the two limiting members 1 correspond one-to-one. After the screw rod 22 passes through the connecting block 21 of one limiting member 1, it continues to pass through the connecting block 21 of the other limiting member 1 at the corresponding position. After the multiple screw rods 22 are installed, the positions of the two steel cages 3 are restricted, so that the ends of multiple main bars 31 of the two steel cages 3 correspond one-to-one. To a certain extent, this eliminates the need to constantly adjust the position of each main bar 31 when connecting the main bars 31 of the steel cages 3, making it easier to connect the main bars 31 of two adjacent steel cages 3 into a whole.

[0023] The working principle of this embodiment is as follows: When the reinforcing cage 3 is hoisted, firstly, multiple lower arc-shaped plates 131 of the limiting member 1 are bolted together to form a lower limiting ring 13. The lower limiting ring 13 is sleeved on the end of the reinforcing cage 3. Then, the upper limit rod 12 of the upper arc-shaped plate 111 is inserted into the corresponding position of the reinforcing bar interval. Then, the upper limit rod 12 is moved towards the lower limiting rod 14, so that multiple main reinforcing bars 31 are in contact with the corresponding positions of the inner sidewalls of multiple fixed frames 15. Then, the upper arc-shaped plate 111 is in contact with the corresponding position of the lower arc-shaped plate 131. Then, the limiting post 17 is inserted into the limiting hole 16 of the upper arc-shaped plate 111 and extends into the limiting hole 16 of the lower arc-shaped plate 131. Finally, the remaining lower arc-shaped plates 131 are installed on the corresponding positions of the upper arc-shaped plate 111. On plate 111, multiple main bars 31 of the steel cage 3 are respectively attached to the corresponding positions of multiple fixed frames 15 to limit the position of multiple main bars 31. After two limiting members 1 are installed at two adjacent ends of the steel cage 3, the position of the steel cage 3 suspended in the air is adjusted so that the positions of multiple connecting blocks 21 on the two limiting members 1 correspond one-to-one. The threaded rod 22 passes through the connecting block 21 of one limiting member 1 and then continues to pass through the connecting block 21 of the other limiting member 1 at the corresponding position. After the multiple threaded rods 22 are installed, the position of the two steel cages 3 is limited. To a certain extent, it is not necessary to constantly adjust the position of each main bar 31 when connecting the main bars 31 of the steel cage 3, which makes it easier to connect the main bars 31 of two adjacent steel cages 3 into a whole.
