Description

Technical Field

[0001] The utility model relates to the technical field of cast-in-place pile construction, in particular to an over-casting control device for concrete cast-in-place piles. Background Art

[0002] In the construction of building engineering, when the pouring height of concrete bored piles is close to the pile top, the actual elevation of the concrete bored piles is often measured by tying a heavy hammer with a measuring rope or directly using square wood and steel bars to determine the over-pouring height of the concrete. In the measurement process, because the measuring rope is often deformed during long-term use and it is difficult to identify the separation interface between concrete and slurry when the measuring hammer or square wood is lowered to the actual position, it places great demands on the construction personnel's process technology and construction experience. Most construction units ensure the construction quality of concrete bored piles by increasing the over-pouring height of concrete. This construction not only wastes concrete raw materials but also increases the amount of subsequent slurry chiseling work. Utility Model Content

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a concrete cast-in-place pile over-pouring control device.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A concrete bored pile over-pouring control device comprises a host and a sensor electrically connected via a communication line, wherein the sensor is fixed to the elevation position of a steel cage via a fixing assembly, the sensor is adapted to monitor the position change of the concrete surface, and the host is adapted to receive a threshold signal from the sensor and issue an alarm via an alarm.

[0006] The alarm includes an alarm light and / or a buzzer.

[0007] The fixing assembly comprises a base, the sensor is detachably connected to the base, and the base is fixed to the steel cage via a connecting piece.

[0008] The connecting member comprises a cable tie or a binding rope.

[0009] A connecting cavity is constructed in the base, and a locking hole connected to the connecting cavity is arranged on the side wall of the base. A locking plate is correspondingly arranged on the sensor, and the locking plate extends into the locking hole. The locking plate is elastic. A clamping rod is inserted in the connecting cavity, and the clamping rod passes between the two locking plates and can drive the two locking plates away from each other. An elastic buckle is also arranged in the connecting cavity, and one end of the clamping rod is fixed to the communication line, and the other end of the clamping rod is buckled with the elastic buckle.

[0010] The locking holes are arranged in multiple groups along the axial direction of the connecting cavity.

[0011] Flanges are formed on the side walls facing away from each other of the two locking plates in the same group.

[0012] The insertion end of the abutment rod is configured with a guiding slope.

[0013] The beneficial effect of the utility model is that during the pouring of pile foundation, when the normal concrete surface below the floating slurry approaches the sensor, the lower normal concrete is about to reach the designed pile top elevation, and the alarm will sound an alarm, prompting it to be poured in place immediately; at this time, the pouring speed should be slowed down, and a small amount of concrete should be put into the hopper one by one until the alarm reaches the elevation position, indicating that all the concrete below the designed pile top elevation in the hole is normal, and the pouring of pile foundation is completed. Compared with the prior art, the utility model can monitor and sound the alarm on the concrete surface in time through the cooperation of the sensor and the alarm, thereby abandoning the situation of using construction experience to judge the concrete surface, greatly improving the pouring accuracy, and not prone to over-pouring.

[0019] The following will be combined with the embodiments to clearly and completely describe the technical solution 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 those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4As shown, a concrete pile over-pouring control device includes a host 2, a sensor 3 is electrically connected to the host 2 through a communication line 1, and an alarm 5 is also provided on the host 2. When in use, the sensor 3 can be fixed at the elevation position of the steel cage 16 through a fixing component 4; as the pile foundation pouring proceeds, when the normal concrete surface below the floating slurry approaches the sensor 3, at this time, the lower normal concrete is about to reach the designed pile top elevation, and the alarm 5 alarms it, prompting it to be poured in place immediately; at this time, the pouring speed should be slowed down, and a small amount of concrete should be put into the hopper one by one until the alarm 5 alarms that the elevation position has been reached, indicating that all the concrete below the designed pile top elevation in the hole is normal, and the pile foundation pouring is completed.

[0021] Among them, sensor 3 is a prior art, so it will not be described in detail in this disclosure. For example, sensor 3 can be a pressure sensor 3, or a probe sensor 3. As the concrete surface rises, the probe will bounce under the push of the concrete surface, and the position change of the concrete surface can be monitored. The monitoring signal of sensor 3 will be transmitted to host 2 through communication line 1. For example, at the two threshold heights of the above-mentioned concrete surface, alarm 5 can issue different alarms to alert and remind construction personnel.

[0022] In some embodiments, the alarm 5 may be an alarm light or a buzzer, and preferably the alarm light or the buzzer may be simultaneously provided on the host 2. For example, when the concrete surface is at the threshold of the proximity sensor 3, the alarm light flashes yellow and the buzzer sounds, thereby alerting the construction personnel; when the concrete surface reaches the elevation position, the alarm light flashes green and the buzzer sounds, thereby prompting the construction personnel.

[0023] In some embodiments, the fixing assembly 4 preferably includes a base 6, and the sensor 3 is detachably connected to the base 6. For example, the base 6 can be fixed to the steel cage 16 via a connector 7. Preferably, the connector 7 can include a cable tie or a binding rope. When the sensor 3 is fixed, it is only necessary to install the sensor 3 on the base 6, and the base 6 can be conveniently tied to the steel cage 16 via a cable tie, thereby realizing convenient installation of the sensor 3.

[0024] For example, a connecting cavity 8 may be constructed in the base 6, and a locking hole 9 connected to the connecting cavity 8 is arranged on the side wall of the base 6, and two locking blocks are arranged in a group and multiple groups are arranged along the axial direction of the connecting cavity 8. Multiple groups of locking members are correspondingly arranged on the side wall of the sensor 3, and each group of locking members may include opposite locking sheets 10. Among them, the locking sheets 10 are made of elastic material. When the sensor 3 is connected to the base 6, the corresponding group of locking sheets 10 can be inserted into the locking hole 9 to achieve the initial connection between the two.

[0025] More specifically, a clamping rod 11 is fixed on the communication line 1, and the clamping rod 11 is adapted to be inserted into the connection cavity 8. At the same time, an elastic buckle 12 is also provided in the connection rod, and a corresponding clamping portion 15 is constructed on the clamping rod 11. As the clamping rod 11 is inserted, the clamping rod 11 will be buckled with the elastic buckle 12 through the clamping portion 15, thereby limiting the clamping rod 11 from being disengaged from the connection cavity 8. In addition, the clamping rod 11 is also adapted to pass between two locking plates 10 of the same group when inserted into the connection cavity 8. At this time, the two locking plates 10 will be supported by the clamping rod 11 and move away from each other, so the locking plates 10 will not easily be disengaged from the locking hole 9, thereby limiting the disengagement of the sensor 3 away from the base 6, thereby achieving a stable connection between the sensor 3 and the base 6 when in use. Figure 4 The double-headed arrow in FIG. 1 shows the direction in which the locking piece 10 deforms and rebounds under the resistance of the abutting rod 11 .

[0026] In a preferred example, flanges 13 can be constructed on the opposite side walls of the two locking pieces 10 in the same group. When the two locking pieces 10 are away from each other, the flanges 13 can be buckled on the inner wall of the connecting cavity 8, so that the locking piece 10 is less likely to fall out of the locking hole 9. In addition, a guiding slope 14 can be constructed on the insertion end of the abutting rod 11. Under the guidance of the guiding slope 14, the two locking pieces 10 are more likely to expand away from each other, making the installation process of the sensor 3 more labor-saving and reliable.

[0027] After the pile foundation is poured, the construction workers can pull the communication line 1 vertically to make the clamping rod 11 disengage from the elastic buckle 12 and detach from the connecting cavity 8. At this time, the two locking plates 10 in the same group will restore the initial spacing. At this time, continue to pull the communication line 1 horizontally, the locking plate 10 will disengage from the locking hole 9, and then pull up the sensor 3 for recovery for subsequent over-pouring control operations.

[0028] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
