Description

Technical Field

[0001] This utility model relates to the field of construction tools, and in particular to a steel cage storage stool that adapts to the undulations of the foundation pit ground. Background Technology

[0002] An excavation pit is an underground space excavated during the construction of a building or structure for the construction of its underground structure. The bottom of the excavation pit is typically constructed using cast-in-place piles. During construction...

[0003] The pile positions are marked on the foundation, and the reinforcing cage is pre-placed on the pit surface. A drilling rig is used to excavate the hole. After excavation, the position for the reinforcing cage is reserved in the drilled hole. The reinforcing cage is then lowered into the pile hole using a hoisting method, followed by concrete pouring. The ground after excavation is usually uneven. While the reinforcing cage will not be affected in the short term, during rainy weather or when construction needs to be suspended due to adjustments in the construction plan, the reinforcing cage needs to be placed on the pit surface for an extended period. The uneven surface can cause the reinforcing cage to bend and deform, resulting in poor straightness and affecting construction quality. Utility Model Content

[0004] To solve the above problems, this utility model proposes a steel cage storage bench that adapts to the undulations of the foundation pit ground.

[0005] The technical solution of this utility model is: a steel cage storage bench adapted to the undulation of the foundation pit ground, including an arc-shaped support ring and two retractable legs symmetrically connected to the bottom of the arc-shaped support ring. The retractable legs are arranged vertically, and the upper end of the retractable legs is connected to the arc-shaped support ring. The retractable legs include a sleeve seat, a lifting rod and a nut sleeve. The lifting rod is fitted into the sleeve seat and can move up and down in the sleeve seat. The sleeve seat and the lifting rod are connected by a sliding sleeve structure. An adjustment mechanism is provided between the upper part of the sleeve seat and the lifting rod. The lifting rod is driven to rise or fall in the sleeve seat through the adjustment mechanism. A square seat plate is provided at the lower end of the sleeve seat.

[0006] Preferably, the adjustment mechanism includes a drive component that is cylindrical in shape and an annular groove provided on the upper part of the outer side of the sleeve seat. The drive component is rotatably sleeved on the upper part of the sleeve seat. An annular boss that matches and is inserted into the annular groove is provided in the middle of the inner side of the sleeve seat. Lubricating oil is injected between the annular boss and the annular groove. The upper edge of the annular groove is chamfered to reduce the friction between the annular groove and the annular boss. A nut sleeve is coaxially provided on the upper end of the drive component. The nut sleeve is threadedly connected to the lifting rod. The outer side of the nut sleeve is provided with anti-slip texture.

[0007] Preferably, the upper end of the lifting rod is fixedly connected to a sliding support, and the bottom surface of the arc-shaped support ring is coaxially provided with an arc-shaped guide rail. The arc-shaped guide rail can generate a reinforcing structure in the arc-shaped support ring. A groove is formed between the two ear plates on the sliding support, and the arc-shaped guide rail is slidably connected in the groove.

[0008] Preferably, the side of the arc-shaped guide rail is evenly distributed with several through holes, and the two ends of the ear plate are provided with insertion holes corresponding to the positions of the through holes. The distance between adjacent through holes is the same as the distance between two insertion holes, and a limit bolt is connected between the insertion hole and the through hole.

[0009] Preferably, the upper end of the lifting rod is provided with a U-shaped seat, and the bottom surface of the sliding support is provided with a triangular hinge lug that is fitted into the U-shaped seat.

[0019] Example 1, see appendix Figure 1-3 A storage bench for a steel cage 4 adapted to the undulations of a foundation pit includes an arc-shaped support ring 1 and two retractable legs 2 symmetrically connected to the bottom of the arc-shaped support ring 1. The upper ends of the retractable legs 2 are connected to the arc-shaped support ring 1. The two retractable legs 2 and the arc-shaped support ring 1 together form a special storage bench for the steel cage 4. The retractable legs 2 include a sleeve seat 21 and a lifting rod 22. The lifting rod 22 is fitted into the sleeve seat 21. The sleeve seat 21 and the lifting rod 22 are connected by a sliding sleeve structure. An adjustment mechanism is provided between the upper parts of the sleeve seat 21 and the lifting rod 22. The lifting rod 22 is driven to slide within the sleeve seat 21 through the adjustment mechanism to achieve its height adjustment. A square seat plate 211 is provided at the lower end of the sleeve seat 21. The square seat plate 211 increases the contact area between the lower end of the leg and the ground, thereby improving its support stability.

[0020] The upper end of the lifting rod 22 is fixedly connected to a sliding support 3. The bottom surface of the arc-shaped support ring 1 is coaxially provided with an arc-shaped guide rail 11. A groove 32 is formed between the two ear plates 31 on the sliding support 3. The arc-shaped guide rail 11 is slidably connected in the groove 32. The relative height between the arc-shaped support ring 1 and the support leg is adjusted by sliding the two sliding supports 3 relative to the arc-shaped guide rail 11. The distance between the support legs is also adjusted accordingly. Therefore, the storage stool can be adapted to the size of the steel cage 4, improving the flexibility of use.

[0021] The side of the arc-shaped guide rail 11 is evenly distributed with several through holes 12. At both ends of the ear plate 31, there are insertion holes corresponding to the positions of the through holes 12. Limiting bolts 33 are connected between the insertion holes and the through holes 12. After the relative positions between the sliding support 3 and the arc-shaped support ring 1 are adjusted, they are locked by the limiting bolts 33 to ensure that they have sufficient support strength for the steel cage 4.

[0022] The upper end of the lifting rod 22 is provided with a U-shaped seat 221. The bottom surface of the sliding support 3 is provided with a triangular hinge ear 34 that fits into the U-shaped seat 221. The triangular hinge ear 34 and the U-shaped seat 221 are hinged by a hinge bolt 35. This hinge structure allows the upper end of the telescopic support leg 2 to rotate relative to the arc-shaped support ring 1 to adjust the included angle. The height of the arc-shaped support ring 1 can be adjusted by the telescopic support leg 2, and its tilt angle can also be adjusted.

[0023] Both ends of the arc-shaped guide rail 11 are provided with limiting plates 13, which are fixedly connected between the arc-shaped guide rail 11 and the arc-shaped support ring 1.

[0024] In this embodiment, when storing the rebar cage 4, multiple storage benches are placed side by side on the bottom of the foundation pit. The height of the telescopic support legs 2 is then adjusted according to the height difference between the storage benches. At the same time, the height difference between the two telescopic support legs 2 of the same storage bench can be made according to the inclination of the arc-shaped support ring 1. By adjusting the height and inclination angle of the arc-shaped support ring 1, adjacent storage benches are made to be horizontally aligned. Then, the rebar cage 4 is hoisted between each arc-shaped support ring 1. The arc-shaped support ring 1 can stably and horizontally support the rebar cage 4, avoiding the phenomenon of bending and deformation of the rebar cage 4 when placed on uneven ground for a long time.

[0025] Example 2, see appendix Figure 3-6 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the adjustment mechanism includes a driving member 23 that is cylindrical in shape and an annular groove 212 provided on the upper part of the outer side of the sleeve seat 21. The driving member 23 is rotatably sleeved on the upper part of the sleeve seat 21. The inner side of the sleeve seat 21 is provided with an annular boss 231 that matches and is inserted into the annular groove 212. The size of the annular boss 231 is slightly smaller than the size of the annular groove 212 to ensure that the annular boss 231 can slide and rotate smoothly in the annular groove 212. The upper end of the driving member 23 is coaxially provided with a nut sleeve 232, which is threadedly connected to the lifting rod 22.

[0026] When the adjustment mechanism is in use, the rotating drive 23, under the axial limiting action of the annular boss 231 and the annular groove 212, can rotate at a fixed position on the upper end of the sleeve seat 21. During the rotation, the nut sleeve 232 at its upper end drives the lifting rod 22 through the thread, realizing the sliding lifting of the lifting rod 22 in the sleeve seat 21, thereby adjusting the tilt angle and height of the upper arc support ring 1.
