Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for pouring concrete pile foundations, in particular to an automatic reminder device for over-pouring of concrete pile foundations. Background Art

[0002] Pile foundation is a deep foundation composed of a pile and a pile cap connected to the top of the pile (referred to as cap) (see figure) or a single pile foundation connected by a column and a pile foundation, referred to as pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation; building pile foundations are usually low cap pile foundations, and pile foundations are widely used in high-rise buildings.

[0003] The existing raw materials for pile foundations are generally concrete, so they are also called concrete pile foundations. When pouring concrete pile foundations, first build an internal steel cage, then build a pouring mold, and then pour concrete into the completed pouring mold. While pouring, vibrate the concrete with a vibrator, and a staff member is located at the mold mouth. When pouring concrete pile foundations, the pouring height of the concrete needs to be controlled.

[0004] However, when pouring concrete pile foundation, the pouring amount needs to be supervised by experienced people. If the staff cannot control the amount of concrete pouring, resulting in over-pouring of concrete, the over-pouring concrete needs to be handled manually in a timely manner, which not only affects the construction progress of the pile foundation and causes concrete waste, but also is time-consuming and labor-intensive, and does not meet the existing needs of efficient and fast construction. Therefore, we propose an automatic reminder device for over-pouring of concrete pile foundation. Utility Model Content

A connecting air pipe is fixedly connected to the inflatable air pump, one end of the connecting air pipe passes through the buoyancy board and is connected to the buoyancy airbag, and the connecting air pipe is communicated with the buoyancy airbag.

[0010] The interior of the buoyancy board is hollow and the bottom end is open, and the bottom end of the buoyancy air bag is flush with the bottom end of the buoyancy board.

[0014] The utility model has a reasonable structural design. The buoyancy airbag is used to increase the buoyancy of the buoyancy plate.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See attached Figure 1-4 ;

[0024] A concrete pile foundation overfilling automatic reminder device comprises a controller 1 and a center block 2, wherein two symmetrically distributed connecting rods 5 are slidably installed at the bottom end of the center block 2, and connecting blocks 13 are arranged at the top ends of the two connecting rods 5, and the connecting blocks 13 are located in the guide hole 14 of the center block 2, and a spring 11 is clamped in the guide hole 13, and a pressure sensor 12 is installed at the top end of the spring 11 (during installation, the top of the guide hole can press the pressure sensor and the spring into the guide hole through a pressure cover), the pressure sensor 12 is fixed inside the center block 2 and is electrically connected to the controller 1, and buoyancy plates 4 are fixed at the bottom ends of the two connecting rods 5, and buoyancy air bags 8 are installed inside the buoyancy plates 4, and two inflatable air pumps 6 are fixed on the upper surface of the buoyancy plates 4, and the inflatable air pumps 6 are fixed on the upper surface of the inflatable air pumps 6. A connecting air pipe 7 is connected, one end of which passes through the buoyancy plate 4 and is connected to the buoyancy airbag 8. The connecting air pipe 7 is connected to the buoyancy airbag 8. When the concrete pile foundation is poured, the buoyancy airbag 8 and the buoyancy plate 4 will move upward with the concrete. The buoyancy plate 4 drives the connecting rod 5 to move toward the inside of the center block 2. The spring 11 is compressed by the connecting rod 5 and the pressure detected by the pressure sensor 12 continues to increase. The pressure sensor 12 feeds back the pressure data to the controller 1. After receiving the data, the controller 1 performs data conversion and converts the pressure data into the upward movement distance of the buoyancy plate 4. According to the upward movement data of the buoyancy plate 4, the construction personnel can accurately control the degree of concrete pouring to avoid over-pouring of concrete and overflow from the pile foundation mold during the pouring of the concrete pile foundation, thereby avoiding waste.

[0025] Furthermore, the interior of the buoyancy board 4 is hollow and the bottom is open, the bottom of the buoyancy airbag 8 is flush with the bottom of the buoyancy board 4, and the open bottom of the buoyancy board 4 allows the buoyancy airbag 8 to expand downward when inflated, thereby changing the buoyancy of the buoyancy board 4.

[0026] Furthermore, a casting pipe positioning hole 9 is penetrated through the center of the central block 2 and the buoyancy plate 4, and vibrating rod positioning holes 10 are distributed on both sides of the casting pipe positioning hole 9. The inner diameter of the vibrating rod positioning hole 10 is greater than or equal to the outer diameter of the concrete casting pipe, and the inner diameter of the casting pipe positioning hole 9 is greater than or equal to the outer diameter of the vibrating rod. The presence of the casting pipe positioning hole 9 and the vibrating rod positioning hole 10 facilitates the vibrating rod and the concrete casting pipe to pass through the central block 2 and the buoyancy plate 4 into the concrete pile foundation mold, thereby successfully completing the concrete pouring and vibration of the concrete.

[0027] like Figure 1 and Figure 2As shown, further, four supporting rods 3 distributed in a circular array are installed on the outer surface of the central block 2, and the supporting rod 3 includes an adjusting rod 32, one end of the adjusting rod 32 is fixed on the outer surface of the central block 2, and the other end of the adjusting rod 32 is slidably installed with the adjusting rod 32, and the end of the adjusting rod 32 away from the central block 2 is bent downward, and a positioning clamping groove 33 is opened at this end of the adjusting rod 32, and a limiting screw 34 is penetrated through the outer surface of the adjusting rod 32, and the limiting screw 34 is connected to the adjusting rod 32 by a thread, and the threaded end of the limiting screw 34 penetrates the adjusting rod 32 and extends into the positioning clamping groove 33. Pushing the adjusting rod 32 to slide on the outside of the adjusting rod 32 can change the distance between the adjusting rod 32 and the central block 2, thereby changing the position of the positioning clamping groove 33 according to different sizes of concrete pile foundation molds, and then clamping the positioning clamping groove 33 on the top of the concrete pile foundation mold, and tightening the limiting screw 34, so that the device is suitable for concrete pile foundation molds of different sizes, and is easy to install and disassemble.

[0028] Working principle: First, push the adjusting rod 32 to slide on the outside of the adjusting rod 32 to change the distance between the adjusting rod 32 and the center block 2, and ensure that the positioning card slot 33 is located at the top of the concrete pile foundation mold, then dock the adjusting rod 32 with the concrete pile foundation mold through the positioning card slot 33, and use a tool to tighten the limit screw 34, then insert the concrete pouring pipe from the pouring pipe positioning hole 9 and pass through the center block 2 and the buoyancy plate 4, then insert the vibrating rod into the vibrating rod positioning hole 10, so that the vibrating rod passes through the center block 2 and the buoyancy plate 4, and then pour concrete into the concrete pile foundation through the concrete pouring pipe. As concrete accumulates in the casting of the pile foundation mold, the concrete will push the buoyancy plate 4, the buoyancy airbag 8, and the connecting rod 5 to move upward. At this time, the connecting rod 5 compresses the spring 11 and gradually increases the pressure on the pressure sensor 12. The pressure sensor 12 feeds back the pressure data to the controller 1. The pressure data is received by the controller 1 and converted into the upward movement data of the buoyancy plate 4 after calculation by the internal chip of the controller 1. According to the upward movement data of the buoyancy plate 4, the construction personnel can accurately control the degree of concrete pouring to avoid over-pouring of concrete and overflow from the pile foundation mold during concrete pile foundation pouring, thereby avoiding waste.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
