Description

Pile head top surface elevation control alarm tool Technical Field

[0001] This utility model belongs to the technical field of pile foundation construction equipment, specifically relating to a pile head top surface elevation control alarm tool. Background Technology

[0002] A cast-in-place concrete pile is a type of pile constructed by drilling a hole in place and pouring in concrete or reinforced concrete. In building construction, foundation construction is a crucial step, and before the foundation is built, the pile supports and components must be installed. Traditional pile foundation concrete pouring often results in over- or under-pouring of concrete. When over-pouring occurs, the solution is often to break or cut the pile, which not only wastes concrete materials and increases construction costs but also delays the project and affects construction efficiency. The traditional method for measuring the height of the concrete pouring is to use a measuring rope to measure the top surface of the concrete after pouring. However, the measuring rope is cumbersome, requiring frequent insertion and removal from the pile hole, and the small graduations on the rope make data reading difficult. Therefore, construction workers may not use the measuring rope correctly, leading to over- or under-pouring of concrete. Summary of the Invention

[0003] The present invention aims to provide a tooling for controlling and alarming the elevation of the top surface of the pile head, so as to solve the problem of excessive or insufficient grouting of pile foundation concrete.

[0004] To achieve the above objectives, the present invention provides a pile head top surface elevation control alarm fixture, comprising a support, an alarm, a power supply, and a control box. The control box is fixedly connected to the support. The control box contains a first conductive element, a second conductive element, and several elastic elements. The first conductive element is fixedly installed on the top wall of the control box, and the second conductive element is located below the first conductive element. The elastic elements support the second conductive element. A connecting rope is fixedly connected to the second conductive element. A through hole is provided on the bottom wall of the control box for the connecting rope to pass through. A force-bearing device is fixedly connected to the bottom end of the connecting rope. When the tension of the force-bearing device on the connecting rope decreases, the second conductive element contacts the first conductive element, and the alarm is powered on.

[0005] The working principle and beneficial effects of this scheme are as follows: In this scheme, the support is placed on the pouring operation platform, and the force-bearing device is suspended at the top surface of the set pile head concrete. As the concrete is poured into the pile hole, the concrete level in the pile hole rises to the height of the force-bearing device, applying an upward lifting force to the device. The tension of the force-bearing device on the connecting rope decreases or even disappears, while the second conductive element contacts the first conductive element under the elastic force of the elastic element. The alarm is then energized and emits an alarm signal to warn the construction personnel to stop pouring, thus avoiding over-pouring or under-pouring of concrete. Therefore, this scheme effectively solves the problem of over-pouring or under-pouring of concrete, avoiding economic losses. Moreover, the construction personnel only need to set up the tooling in this scheme before pouring concrete, making the operation simple.

[0006] Optionally, the control box is provided with a guide rod, the bottom end of which is fixedly connected to the bottom wall of the control box, and the second conductive component is provided with a guide hole for the guide rod to pass through.

[0007] In this design, the second conductive component moves vertically along the guide rod to ensure that the direction of movement of the second conductive component remains unchanged, thereby ensuring that the second conductive component remains horizontal and preventing it from tilting.

[0008] Optionally, it also includes a switch, wherein when the second conductive element contacts the first conductive element, the switch, the alarm, and the power supply form a series circuit.

[0009] In this design, the alarm will only be powered on and operational when the switch is closed and the second conductive element is in contact with the first conductive element; when the switch is open, the alarm will not be powered on even if the second conductive element is in contact with the first conductive element. Thus, construction personnel can disconnect the switch to stop the alarm from operating.

[0010] Optionally, the force-bearing device is a hollow instrument.

[0011] In this scheme, when the force-bearing device is a hollow instrument, it is easier for the force-bearing device to float when the concrete liquid level in the pile hole rises to the height of the force-bearing device.

[0012] Optionally, the control box includes a box body and a cover, the top of the box body is open, the cover is used to close the top opening of the box body, and the cover and the box body are detachably connected.

[0013] In this design, the cover is separated from the box, exposing the opening at the top of the box, which facilitates the inspection and maintenance of the first conductive component, second conductive component, and other devices inside the control box.

[0014] Optionally, a screw is fixedly connected to the top of the box body, and a locking nut is threaded onto the screw. The cover body has an installation hole for the screw to pass through.

[0015] In this design, after the cover passes through the screw, the cover is locked onto the box by a locking nut, thus achieving a detachable connection between the cover and the box.

[0016] Optionally, the alarm is an audible and visual alarm.

[0017] In this solution, the alarm emits both sound and light signals after being powered on, simultaneously alerting construction personnel through both hearing and sight.

[0018] Optionally, the bracket is H-shaped.

[0019] In this design, when the support is I-shaped, its stability is better when placed on the injection operation platform. Attached Figure Description

[0024] The following detailed description illustrates the specific implementation method:

[0025] The markings in the accompanying drawings include: bracket 1, alarm 2, power supply 3, switch 4, control box 5, box body 510, cover 520, mounting hole 521, first conductive element 6, second conductive element 7, guide post 8, elastic element 9, connecting rod 10, connecting rope 11, force receiver 12, grouting operation platform 13, window 131, pile hole 14, screw 15, and locking nut 16.

[0026] Example 1

[0027] This embodiment is basically as shown in Figures 1 and 2: a pile head top surface elevation control alarm fixture, including a bracket 1, an alarm 2, a power supply 3, a switch 4, and a control box 5. The bracket 1 is I-shaped, and the control box 5 is welded to the middle of the bracket 1. Referring to Figure 3, the control box 5 contains a first conductive element 6, a second conductive element 7, a guide post 8, and several elastic elements 9. The first conductive element 6 is connected to the top wall of the control box 5 via a connecting rod 10. The second conductive element 7 is located below the first conductive element 6. The elastic elements 9 support the second conductive element 7; specifically, the bottom end of the elastic element 9 is welded to the bottom wall of the control box 5, and the top end of the elastic element 9 abuts against the bottom wall of the second conductive element 7. In this embodiment, the elastic element 9 is a spring, and there are two elastic elements 9, symmetrically distributed along the vertical central axis of the second conductive element 7. The guide post 8 is insulated, and its bottom end is welded to the bottom wall of the control box 5. The second conductive element 7 has a guide hole through which the guide post 8 passes.

[0028] A connecting rope 11 is bonded to the center of the second conductive element 7. Through holes for the connecting rope 11 to pass through are provided on the bottom wall of the control box 5 and the bracket 1. A force-bearing device 12 is bonded to the bottom end of the connecting rope 11. When the tension of the force-bearing device 12 on the connecting rope 11 decreases, the second conductive element 7 contacts the first conductive element 6, and the alarm 2 is energized. In another embodiment, the force-bearing device 12 is a hollow object, such as a hollow sphere. Compared to a solid object, a hollow object is more likely to float on the surface of the concrete liquid.

[0029] In addition, both the alarm 2 and the power supply 3 are mounted on the outer wall of the control box 5 by bolts. In this embodiment, the alarm 2 is an audible and visual alarm 2. The power supply 3 supplies power to the alarm 2, and the switch 4 controls the on / off state of the circuit. Specifically, when the second conductive element 7 contacts the first conductive element 6, the switch 4, the alarm 2, and the power supply 3 form a series circuit. At this time, when the switch 4 is closed, the alarm 2 is powered on and works; when the switch 4 is open, the alarm 2 is powered off and stops working.

[0030] In actual use, the grouting operation platform 13 is equipped with a window 131 for lowering the force-bearing device 12. The construction personnel pass the force-bearing device 12 through the window 131 and then place the support 1 on the grouting operation platform 13. At this time, the force-bearing device 12 is suspended in the pile hole 14 by the connecting rope 11, and the force-bearing device 12 is located at the top surface of the set pile head concrete. Moreover, the connecting rope 11 is taut by the tension of the force-bearing device 12, which applies a downward force to the second conductive element 7. The second conductive element 7 compresses the elastic element 9, resulting in a distance between the second conductive element 7 and the first conductive element 6.

[0031] After the support 1 is installed, the construction workers close the switch 4. As the concrete is poured, the level of the concrete in the pile hole 14 rises. When the level of the concrete rises to the height of the force-bearing device 12, the force-bearing device 12 receives the upward lifting force exerted on it by the concrete. The tension of the force-bearing device 12 on the connecting rope 11 decreases or even disappears, and the connecting rope 11 slackens. Under the elastic force of the elastic element 9, the second conductive element 7 moves upward along the guide column 8 and comes into contact with the first conductive element 6. At this time, the series circuit is closed, the alarm 2 is powered on, and emits sound and light signals to warn the construction workers to stop the concrete pouring through hearing and vision, effectively solving the problem of excessive or insufficient concrete pouring.

[0032] After the alarm 2 is powered on, the construction personnel can turn off the switch 4, and the alarm 2 will stop working. Then, the construction personnel will lift the support 1 from the grouting operation platform 13 until the force-bearing device 12 leaves the pile hole 14 through the window 131 of the grouting operation platform 13. After cleaning the force-bearing device 12, the tooling will be put away for the next use.

[0033] Example 2

[0034] The difference between this embodiment and embodiment one is as follows: As shown in Figure 4, in this embodiment, the control box 5 includes a box body 510 and a cover 520. The top of the box body 510 is open, and the cover 520 is used to cover the top opening of the box body 510. The cover 520 and the box body 510 are detachably connected. Specifically, a screw 15 is welded to the top of the box body 510, and a locking nut 16 is threaded onto the screw 15. The cover 520 has a mounting hole 521 for the screw 15 to pass through.

[0035] In this embodiment, the cover 520 passes through the screw 15 and covers the box 510. The locking nut 16 is tightened to fix the cover 520. When it is necessary to open the control box 5, the locking nut 16 is removed from the screw 15, and then the cover 520 is removed from the box 510, which facilitates personnel to inspect and maintain the components inside the box 510.
