Description

Technical Field

[0001] This utility model relates to the field of pile reinforcement cage positioning technology, specifically to a monitoring device for preventing the reinforcement cage of cast-in-place piles from floating and for positioning. Background Technology

[0002] Cast-in-place piles are piles formed by drilling a hole at a designated location and then pouring cement into the hole using a cement-pouring machine. This is one of the commonly used construction methods in modern building engineering. To increase the strength of the pile, a steel cage is usually embedded in the pile as a supporting framework, which is also a common building construction technique.

[0003] The pre-placed reinforcing cage during the pouring process has the problem of floating up as cement is poured. The floating reinforcing cage will affect the strength of the pile, and the reinforcing cage may tilt or rotate during the floating process, making the pile unusable. Therefore, a device for preventing the reinforcing cage of the cast-in-place pile from floating up and for monitoring its positioning is proposed. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the pre-placed steel cage during the pouring process tends to float upwards as cement is poured. The floating steel cage affects the strength of the pile and may tilt or rotate during the floating process, rendering the pile unusable. This utility model provides a monitoring and positioning device for preventing the steel cage from floating upwards during the pouring process, enabling it to effectively position the steel cage and prevent it from floating upwards during the pouring process.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a monitoring device for preventing the floating and positioning of a cast-in-place pile reinforcement cage, including a pile pit, a reinforcement cage placed inside the pile pit, a positioning plate connected to the outer ring wall of the reinforcement cage, a bonding plate fixedly connected to the positioning plate, one side wall of the bonding plate being bonded to the pit wall of the pile pit, a limiting plate detachably connected to the ground at the top opening of the pile pit, a follower sleeve connected to one side of the limiting plate, and a sleeve column sleeved to the end of the reinforcement of the reinforcement cage.

[0006] As a preferred technical solution of this utility model, the positioning plate is a V-shaped elastic structure, and two bonding plates are provided. The two bonding plates are respectively fixedly connected to the two ends of the positioning plate, and the positioning plate is fixed to the outer ring wall of the steel cage by welding one end.

[0007] As a preferred technical solution of this utility model, one side wall of the bonding plate is an arc-shaped structure corresponding to the pile pit wall. The side wall of the bonding plate opposite to the pile pit wall is provided with a receiving groove. A piercing plate is fixedly connected to the lower edge of the receiving groove. The piercing plate is in an outwardly expanding and inclined state. The receiving groove and the piercing plate are staggered. The tips of the piercing plates on the two bonding plates are both set upward.

[0008] As a preferred technical solution of this utility model, an inner groove is provided in the middle of the limiting plate, and a drive gear is rotatably connected to the inner groove near the edge. A connecting shaft is fixedly connected to the middle of one side wall of the drive gear, and a follower sleeve is fixedly connected to one end of the connecting shaft. A linkage rod is telescopically inserted into the follower sleeve, and a connecting plate is rotatably connected to one end of the linkage rod. The connecting plate is fixedly connected to the top side wall of the sleeve column through its bottom end.

[0009] As a preferred technical solution of this utility model, a driven gear is rotatably connected to one side of the inner groove, and the driven gear is meshed with the driving gear. A docking post is fixed in the middle of one side wall of the driven gear. An alarm is detachably connected to one end side wall of the inner groove. The alarm is a pull-cord type alarm, and the pull cord is wrapped around the docking post. A fixing plate is fixedly connected to the lower edge of the limiting plate away from the driving gear, and screws are inserted and connected to the fixing plate.

[0010] This utility model has the following advantages: the positioning plate is welded to the reinforcing cage. When the reinforcing cage is placed into the pile pit, the piercing plate is tilted upwards, so it will not affect the placement of the reinforcing cage and will also avoid getting stuck in the wall of the steel pipe used for opening. As the steel pipe is pulled out, the elasticity of the positioning plate drives the bonding plate to fit against the wall of the pile pit. When the reinforcing cage floats up, the force it generates will insert the piercing plate into the wall of the pile pit, thereby positioning and restricting the reinforcing cage and preventing it from floating up.

[0011] Inside the rebar cage, a sleeve is fitted onto the top of the rebar. When the rebar cage floats, it drives the follower sleeve to rotate, which in turn drives the drive gear and the driven gear to rotate. This tightens the tension on the alarm, triggering the alarm and alerting the staff to adjust the rebar cage. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 This utility model discloses a monitoring device for preventing the floating and positioning of a reinforcing cage for a cast-in-place pile. It includes a pile pit 1, a reinforcing cage 2 placed inside the pile pit 1, a positioning plate 3 connected to the outer wall of the reinforcing cage 2, a bonding plate 6 fixedly connected to the positioning plate 3, one side wall of the bonding plate 6 being bonded to the pit wall of the pile pit 1, a limiting plate 4 detachably connected to the ground at the top opening of the pile pit 1, a follower sleeve 5 connected to one side of the limiting plate 4, and a sleeve column 14 sleeved on the end of the reinforcing steel of the reinforcing cage 2.

[0018] The positioning plate 3 is a V-shaped elastic structure. Two bonding plates 6 are provided, and the two bonding plates 6 are fixedly connected to the two ends of the positioning plate 3 respectively. The positioning plate 3 is fixed to the outer ring wall of the reinforcing cage 2 by welding one end. One side wall of the bonding plate 6 is an arc-shaped structure corresponding to the pit wall of the pile pit 1. The side wall of the bonding plate 6 opposite to the pit wall of the pile pit 1 is provided with a receiving groove 7. A piercing plate 8 is fixedly connected to the lower edge of the receiving groove 7. The piercing plate 8 is in an outwardly expanding and inclined state. The receiving groove 7 and the piercing plate 8 are staggered. The tips of the piercing plates 8 on the two bonding plates 6 are both set upward.

[0019] The positioning structure technology of this application has the following effects: Because the positioning plate 3 is fixed to the outer wall of the reinforcing cage 2, when the reinforcing cage 2 is placed into the pile pit 1 and the steel pipe is removed, the positioning plate 3 will drive the bonding plate 6 to fit against the pit wall of the pile pit 1 under its own elasticity. When the problem of floating occurs during the grouting process, the bonding plate 6 will be driven to float synchronously against the pit wall as the reinforcing cage 2 moves, thereby driving the piercing plate 8 to be inserted into the pit wall under the drive of this upward buoyancy, thus positioning the reinforcing cage 2. Also, thanks to the positioning of the positioning plate 3 and the bonding plate 6, the problem of the reinforcing cage 2 rotating or tilting can be avoided, ensuring the pile formation rate. Because the receiving groove 7 is opened, the soil pushed out by the piercing plate 8 can be collected, which can prevent the soil loss when the piercing plate 8 is inserted, so that the piercing plate 8 can be inserted into the pit wall faster and more stably.

[0020] An inner groove 9 is provided in the middle of the limiting plate 4. A drive gear 10 is rotatably connected to the inner groove 9 near its edge. A connecting shaft 11 is fixedly connected to the middle of one side wall of the drive gear 10. A follower sleeve 5 is fixedly connected to one end of the connecting shaft 11. A linkage rod 12 is telescopically inserted into the follower sleeve 5. A connecting plate 13 is rotatably connected to one end of the linkage rod 12. The connecting plate 13 is fixedly connected to the top side wall of the sleeve column 14 through its bottom end. A driven gear 15 is rotatably connected to one side of the inner groove 9. The driven gear 15 is meshed with the drive gear 10. A docking column 16 is fixedly connected to the middle of one side wall of the driven gear 15. An alarm 17 is detachably connected to one side wall of the inner groove 9. The alarm 17 is a pull-cord type alarm 17, and the pull cord is wrapped around the docking column 16. A fixing plate 18 is fixedly connected to the lower edge of the limiting plate 4 away from the drive gear 10, and screws are inserted through the fixing plate 18.

[0021] The positioning structure technology of this application has the following effect: the sleeve column 14 is sleeved on the top of the steel cage 2. When the steel cage 2 floats, it will drive the sleeve column 14 to float synchronously. This will drive the linkage rod 12 and the follower sleeve 5 to rotate, thereby driving the drive gear 10 to rotate. Through the meshing connection, the driven gear 15 will be driven to rotate synchronously, thereby winding the pull rope of the alarm 17 to trigger the alarm. This facilitates timely reminders to the staff to adjust the steel cage 2 in a timely manner and reduce the failure rate of piles.

[0022] Specifically, when using this utility model, the reinforcing cage 2 is placed into the pile pit 1, and then the steel pipe is pulled out while pouring. Because the steel pipe is pulled out first, the bonding plate 6 will be attached to the pit wall before contacting the cement. As the reinforcing cage 2 floats up, it can drive the piercing plate 8 to smoothly insert into the pit wall, thereby positioning the reinforcing cage 2 and ensuring smooth pouring. In order to adjust the floating reinforcing cage 2 in time, the limiting plate 4 is fixed to the ground at the pit opening of the pile pit 1 by screws through the fixing plate 18. Then, the sleeve 14 is sleeved on the top of the reinforcing cage 2. In this way, the floating of the reinforcing cage 2 will drive the sleeve 14 to move upward. As the sleeve 14 moves, it will drive the linkage rod 12 and the follower sleeve 5 to rotate, thereby driving the drive gear 10 to rotate, thereby driving the docking column 16 to rotate and winding the pull rope, thereby triggering the alarm 17 to sound an alarm.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
