Description

Technical Field

[0001] The utility model relates to the field of building construction tools, in particular to a reinforcement cage auxiliary installation device with a positioning function. Background Art

[0002] When pouring concrete in the pile foundation, the steel cage needs to be hoisted to the center of the pile hole. Usually, the hoisting rod is welded on the top of the steel cage, and the hoisting construction work is carried out through the hoisting rod.

[0003] The welding process of this direct welding method is time-consuming and labor-intensive, and the hanger bars cannot be recovered after pouring concrete, resulting in material waste.

[0004] To this end, the utility model patent with application number 2017209992637 proposes a bored pile steel cage hoisting device, which suspends the steel cage by setting vertical bars with a hanging function. After the hoisting, the hoisting bars can be removed and recycled, which solves the problems of welding troubles and serious material waste. However, the vertical bars of the patent are fixed in length, which has the problem of limited matching with the hoisting state of steel cages of different sizes, and the hook at the lower end does not have a locking function. There are also problems such as the steel cage rising due to concrete pressure and the hook slipping off, and the hook and the steel cage sliding relative to each other, which affects the construction accuracy of the steel cage.

DETAILED DESCRIPTION

[0022] Example 1, see the attached specification Figure 1 , 3 A steel cage auxiliary installation device with a positioning function includes a square frame bracket 11 and a vertical rod 12 fixedly connected to the middle of the bottom of the square frame bracket 11. The vertical rod 12 is cylindrical. A U-shaped hook 121 is provided at the lower end of the vertical rod 12. The U-shaped hook 121 is used to hang the stirrups at the upper end of the steel cage 17. An arc rod 112 is provided at the upper end of the square frame bracket 11. The arc rod 112 can make the hook of the crane hang to the center position of the square frame bracket 11. The two ends of the arc rod 112 are connected to the upper ends of the two side plates of the square frame bracket 11.

[0023] A number of cross bars 111 are arranged at equal intervals in the square frame bracket 11. The spacing between adjacent cross bars 111 is larger than the size of the cross brace steel pipe 15. The cross bars 111 are used to insert the cross brace steel pipe 15. The cross bars 111 form sockets of different heights. Sockets of different heights can be selected to insert the cross brace steel pipe 15, so as to realize the height adjustment of the square frame bracket 11 in the suspended state, so that it can better adapt to the steel cages 17 of different heights.

[0024] During the construction of this embodiment, an auxiliary installation device is connected to each side of the steel cage 17, and the U-shaped hook 121 of the device is hooked with the stirrups of the steel cage 17, and then the steel cage 17 is lifted by two square frame brackets 11 and placed in the pile hole. After it is placed in place, the cross brace steel pipe 15 is inserted between the cross bars 111 corresponding to the square frame brackets 11, and the cross brace steel pipe 15 is supported on the upper port of the protective steel cylinder 16, completing the lifting and vertical limiting of the steel cage 17.

[0025] Example 2, see the attached specification Figure 4-5 This embodiment is based on the first embodiment. A support rod 13 is slidably mounted in the vertical rod 12. The lower end of the support rod 13 extends from the lower end of the vertical rod 12 and a pressure block 131 is provided at the lower end of the support rod 13. An adjustment locking mechanism is provided between the support rod 13 and the vertical rod 12.

[0026] The adjustment locking mechanism includes a nut seat 122 coaxially arranged at the upper end of the vertical rod 12, and a threaded section 132 is correspondingly arranged on the upper part of the support rod 13. The threaded section 132 is threadedly connected with the nut seat 122. A nut head 133 is arranged at the upper end of the support rod 13. The support rod 13 is driven to rotate by the nut head 133. The threaded section 132 and the nut seat 122 on the support rod 13 interact with each other to realize the height adjustment of the support rod 13 in the vertical rod 12.

[0027] After the U-shaped hook 121 of this embodiment hooks the steel cage 17, the support rod 13 with a telescopic locking function in the vertical rod 12 can extend outward, and the stirrups of the steel cage 17 are pressed against the hook through the pressure block 131 at its lower end, thereby locking the hook and avoiding the problem of the steel cage 17 and the hook slipping off or the hook and the steel cage 17 sliding relative to each other.

[0028] Example 3, see the attached specification Figure 1 On the basis of the first embodiment, this embodiment connects a limiting assembly to the frame-shaped bracket 11, and the limiting assembly includes an elliptical limiting ring 141 and a vertical anchor rod 142. The limiting ring 141 is mounted on the side rods of the frame-shaped bracket 11 between the cross rods 111, and a hook is provided at the upper end of the anchor rod 142, and the hook is connected to the limiting ring 141. After the steel cage 17 is hoisted, the anchor rod 142 is connected to the limiting ring 141, and then the anchor rod 142 is vertically inserted into the foundation soil on one side of the protective steel cylinder 16 to realize the vertical positioning of the steel cage 17, avoid the steel cage 17 from rising due to the internal pressure of the concrete, avoid position deviation, and ensure the quality of the pouring construction.
