Description

Technical Field

[0001] This invention relates to the technical field of building construction equipment, specifically to a rebar cage installation device and a rebar cage installation method. Background Technology

[0002] In recent years, a new construction method for drilling and grouting piles followed by inserting steel cages has emerged in pile foundation engineering. This method involves first drilling a pile hole, then pouring concrete into the pile hole, and finally inserting the steel cage into the concrete inside the pile hole.

[0003] However, the inventors discovered that when inserting and installing steel reinforcement cages into the concrete of the pile body, the alignment of the steel reinforcement cages is poor. This often results in the steel reinforcement cages touching the borehole wall around the pile, causing deviations in the protective layer of the steel reinforcement cages, or the installation elevation of the steel reinforcement cages failing to meet design requirements, leading to quality problems. Summary of the Invention

[0004] This invention proposes a rebar cage installation device and a rebar cage installation method, which improves the alignment of the rebar cage with the pile body during installation and ensures the protective layer and verticality of the rebar cage during installation.

[0005] To this end, the first aspect of this application provides a rebar cage installation device, including a rebar guide rod, wherein the upper part of the rebar guide rod is provided with a guiding mechanism, and the lower part of the rebar guide rod of the guiding mechanism is provided with at least one set of positioning mechanisms.

[0006] By adopting the above technical solution, the guiding mechanism set in this device facilitates the installation of the reinforcing cage and improves the alignment between the reinforcing cage and the pile body during installation. The positioning mechanism can fix the reinforcing cage on this device, and during the lowering of the reinforcing cage, the movement of the reinforcing cage and this device are synchronized, thereby further improving the alignment of the reinforcing cage installation and ensuring the protective layer and verticality of the reinforcing cage during installation.

[0007] Optionally, the top of the reinforcing bar guide rod is equipped with a vibrator and a lifting ring.

[0008] By adopting the above technical solution: by setting up a vibrator to provide impact force during the installation of the reinforcing cage, the lowering depth of the reinforcing cage in the concrete is increased, and at the same time, it plays a role in vibrating the concrete of the pile body, so that the concrete in the pile body fits the reinforcing cage more evenly, and the firmness and stability are better. By setting a lifting ring on the vibrator, it is easy to hoist this device to lower the reinforcing cage for construction.

[0009] Optionally, the guiding mechanism includes a straightening guide sleeve, which is connected to the reinforcing bar guide rod via a connecting assembly, and the plane of the straightening guide sleeve is perpendicular to the reinforcing bar guide rod.

[0010] By adopting the above technical solution: during the installation and lowering of the reinforcing cage to the pile body, the straightening guide sleeve fits against the inner wall of the pile hole, which improves the alignment of the reinforcing cage and the pile body. The plane where the straightening guide sleeve is located is perpendicular to the reinforcing bar guide rod, which further improves the alignment of the reinforcing cage installation.

[0011] Optionally, the straightening guide sleeve is circular, and the connecting assembly includes multiple sets of connecting rods connected to the straightening guide sleeve. One end of the connecting rod is connected to the straightening guide sleeve, and the other end of the connecting rod is connected to the reinforcing bar guide rod.

[0012] By adopting the above technical solution: the circular straightening guide sleeve fits perfectly against the inner wall of the pile hole, the reinforcing bar guide rod is located in the middle of the straightening guide sleeve, and the straightening guide sleeve is fixed to the reinforcing bar guide rod by the connecting rod, thus ensuring the perpendicularity and centering of the reinforcing bar guide rod and the straightening guide sleeve.

[0013] Optionally, the straightening guide sleeve includes multiple arc strips, each of which is connected to the insert guide rod via a telescopic rod. One end of the telescopic rod is connected to the straightening guide sleeve, and the other end of the telescopic rod is connected to the insert guide rod.

[0014] By adopting the above technical solution, the diameter of the straightening guide sleeve composed of multiple arc strips can be adjusted by connecting the arc strips to the reinforcing bar guide rod via a telescopic rod, thus making it suitable for piles of different diameters and improving the applicability of the device.

[0015] Optionally, the positioning mechanism includes a positioning component connected to the reinforcing bar guide rod, the positioning component including a support body connected to the reinforcing bar guide rod, and a guide body provided on the lower side of the support body.

[0016] By adopting the above technical solution, the upper part of the steel cage can be fixedly connected to the straightening guide sleeve of the guide mechanism through the connecting steel bars, and the middle part or other parts of the steel bars can be supported and positioned through the positioning component to prevent the radial position of the steel cage from changing, thereby improving the accuracy of the steel cage installation.

[0017] Optionally, the positioning mechanism includes a positioning assembly connected to the reinforcing bar guide rod. The positioning assembly includes multiple sets of support bodies connected to the reinforcing bar guide rod via telescopic components, and each set of support bodies has a guide body on its lower side.

[0018] By adopting the above technical solution, the overall diameter of the positioning mechanism can also be adjusted by setting a telescopic component to connect the positioning component and the guide rod, which also improves the applicability of the device.

[0019] Optionally, the telescopic assembly includes a main rod connected at one end to the insert guide rod and a secondary rod slidably disposed within the main rod. A spring is provided between one end of the secondary rod located inside the main rod and the main rod, and a snap-fit ​​device is provided between the secondary rod and the main rod.

[0020] By adopting the above technical solution, the position of the sub-rod relative to the mother rod can be adjusted, thereby adjusting the distance between the support body and the guide rod. By adjusting them one by one, support bodies of different diameters can be obtained. After the position is adjusted to the correct position, the positions of the sub-rod and the mother rod can be fixed by the snap-fit ​​device.

[0021] Optionally, the snap-fit ​​component includes a groove on the female rod, a slider on the male rod that mates with the groove, a spring bead on the slider, and a through hole on the groove.

[0022] The second aspect of this application provides a method for installing a reinforcing cage using the aforementioned device, comprising the following steps:

[0023] S1. Drill the hole and pour concrete into the pile body;

[0024] S2. Install the steel cage, insert the reinforcing bar guide rod and positioning mechanism into the steel cage, and fix the upper part of the steel cage to the guide mechanism through the connecting steel bars.

[0025] S3. Lifting the steel cage: The installation device equipped with the steel cage is lifted by the lifting equipment. Under the action of the guiding mechanism and the positioning mechanism, the steel cage can be centered and installed in the pile concrete. After that, the installation device is removed.

[0026] By adopting the above technical solution and construction method, the steel reinforcement cage can be installed conveniently, and the alignment between the steel reinforcement cage and the pile body is improved.

[0027] The working principle and beneficial effects of this application are as follows:

[0028] 1. The guiding mechanism set in this device facilitates the installation of the reinforcing cage and improves the alignment between the reinforcing cage and the pile body during installation. The positioning mechanism can fix the reinforcing cage to this device. During the lowering of the reinforcing cage, the movement of the reinforcing cage and this device are synchronized, thereby improving the alignment of the reinforcing cage installation and ensuring the protective layer and verticality of the reinforcing cage during installation.

[0029] 2. The straightening guide sleeve, composed of multiple arc strips, is connected to the reinforcing bar guide rod by a telescopic rod. This allows the diameter of the straightening guide sleeve to be adjusted, making it suitable for piles of different diameters and improving the applicability of the device.

[0030] 3. The positioning mechanism of this application can adjust the distance between the support body and the guide rod, and adjust them one by one to obtain support bodies of different diameters. After the position is adjusted, the position of the sub-rod and the main rod can be fixed by the snap-fit, which further improves the applicability of this device. Attached Figure Description

Implementation

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0041] Reference Figures 1-4 The first aspect of this application provides a rebar cage installation device, including a rebar guide rod 100, which can be made of steel pipe. The upper part of the rebar guide rod 100 is provided with a guide mechanism 200, which is fixed to the upper part of the rebar guide rod 100 by welding. The lower part of the rebar guide rod 100 is provided with at least one set of positioning mechanisms 300. In this embodiment, one set of positioning mechanisms 300 is provided. Of course, depending on the depth of the pile, multiple sets of positioning mechanisms 300 can be provided to better position and install the rebar cage.

[0042] The basic principle of this embodiment is as follows: the guide mechanism 200 set by this device facilitates the installation of the reinforcing cage and improves the alignment between the reinforcing cage and the pile body during the installation process. The positioning mechanism 300 can fix the reinforcing cage on this device. During the process of lowering the reinforcing cage, the movement of the reinforcing cage and this device is consistent, thereby improving the alignment of the reinforcing cage installation and ensuring the protective layer and verticality of the reinforcing cage during installation.

[0043] Of course, in order to provide the downward impact force and tamping of concrete during the installation of the reinforcing cage, a vibrator 400 is provided at the top of the reinforcing bar guide rod 100 in this embodiment. During the installation of the reinforcing cage, it is vibrated and lowered, and the concrete is tamped at the same time. In order to facilitate the hoisting of the installation, a lifting ring 500 is also provided on the upper part of the vibrator 400.

[0044] By setting up the vibrator 400, the concrete inside the pile body can be more evenly attached to the steel cage, resulting in better firmness and stability. The lifting ring 500 on the vibrator 400 facilitates the hoisting of this device for the lowering of the steel cage during construction.

[0045] Reference Figure 1 and Figure 2 In this embodiment, the guiding mechanism 200 includes a straightening guide sleeve 210, which can be in the shape of a ring. The straightening guide sleeve 210 is connected to the reinforcing bar guide rod 100 through a connecting component 600. The plane of the straightening guide sleeve 210 is perpendicular to the reinforcing bar guide rod 100.

[0046] During the installation and lowering of the reinforcing cage to the pile body, the straightening guide sleeve 210 fits against the inner wall of the pile hole, improving the alignment of the reinforcing cage and the pile body. The plane of the straightening guide sleeve 210 is perpendicular to the reinforcing bar guide rod 100, which further improves the alignment of the reinforcing cage installation.

[0047] In this embodiment, the straightening guide sleeve 210 is circular, such as a steel sleeve, etc. The connecting component 600 includes multiple sets of connecting rods connected to the straightening guide sleeve 210. One end of the connecting rod is connected to the straightening guide sleeve 210, and the other end of the connecting rod is connected to the reinforcing bar guide rod 100.

[0048] The annular straightening guide sleeve 210 fits perfectly against the inner wall of the pile hole. The reinforcing bar guide rod 100 is located in the middle of the straightening guide sleeve 210. The straightening guide sleeve 210 is fixed to the reinforcing bar guide rod 100 by the connecting rod, which ensures the perpendicularity and centering of the reinforcing bar guide rod 100 and the straightening guide sleeve 210.

[0049] Reference Figure 1 and Figure 3 In this embodiment, the positioning mechanism 300 includes a positioning component 310 connected to the reinforcing bar guide rod 100. The positioning component 310 includes a support body 311 connected to the reinforcing bar guide rod 100, and a guide body 312 is provided on the lower side of the support body 311. The upper part of the reinforcing cage can be fixedly connected to the straightening guide sleeve 210 of the guiding mechanism 200 through the connecting reinforcing bar 900. The positioning component 310 can support and position the middle part or other parts of the reinforcing bar, preventing radial positional changes in the reinforcing cage and improving the accuracy of the reinforcing cage installation.

[0050] The second aspect of this embodiment provides a method for installing a reinforcing cage using the above-described device, comprising the following steps:

[0051] S1. Drill the hole and pour concrete into the pile body;

[0052] S2. Install the steel cage, insert the reinforcing bar guide rod 100 and the positioning mechanism 300 into the steel cage, and fix the upper part of the steel cage to the guide mechanism 200 through the connecting steel bar 900.

[0053] S3. Lifting the steel cage: The installation device equipped with the steel cage is lifted by the lifting equipment. Under the action of the guide mechanism 200 and the positioning mechanism 300, the steel cage can be centered and installed in the pile concrete. After that, the installation device is removed.

[0054] By adopting the above technical solution and construction method, the steel reinforcement cage can be installed conveniently, and the alignment between the steel reinforcement cage and the pile body is improved. Example

[0055] Reference Figures 5-7 The difference between this embodiment and embodiment one is that the straightening guide sleeve 210 in this embodiment includes multiple arc strips, each of which is connected to the insert guide rod 100 via a telescopic rod 700. One end of the telescopic rod 700 is connected to the straightening guide sleeve 210, and the other end of the telescopic rod 700 is connected to the insert guide rod 100.

[0056] The straightening guide sleeve 210, composed of multiple arc strips, is connected to the reinforcing bar guide rod 100 by a telescopic rod 700. This allows the diameter of the straightening guide sleeve 210 to be adjusted, making it suitable for piles of different diameters and improving the applicability of the device.

[0057] Reference Figure 6 The positioning mechanism 300 in this embodiment differs from that in Embodiment 1 in that it includes a positioning component 310 connected to the insertion guide rod 100. The positioning component 310 includes multiple sets of support bodies 311 connected to the insertion guide rod 100 via telescopic components 800. Each set of support bodies 311 has a guide body 312 on its lower side. By using telescopic components 800 to connect the positioning component 310 and the insertion guide rod 100, the overall diameter of the positioning mechanism 300 can also be adjusted, thus improving the applicability of this device.

[0058] Reference Figure 7 The telescopic component 800 includes a mother rod 810 connected at one end to the reinforcing bar guide rod 100 and a daughter rod 820 slidably disposed within the mother rod 810. A spring 830 is provided between one end of the daughter rod 820, located inside the mother rod 810, and the mother rod 810. A snap-fit ​​member 840 is provided between the daughter rod 820 and the mother rod 810. The position of the daughter rod 820 relative to the mother rod 810 can be adjusted, thereby adjusting the distance between the support body 311 and the reinforcing bar guide rod 100. By adjusting each component individually, support bodies 311 of different diameters can be obtained. After the position is adjusted to the correct position, the positions of the daughter rod 820 and the mother rod 810 can be fixed by the snap-fit ​​member 840.

[0059] The snap-fit ​​component 840 includes a groove 841 on the mother rod 810, and a slider 842 on the son rod 820 that cooperates with the groove 841. The slider 842 has a spring bead 843, and the groove 841 has multiple through holes 844. The cooperation between the groove 841 and the slider 842 prevents the son rod 820 and the mother rod 810 from rotating radially. By setting the spring bead 843, when it is necessary to adjust the relative position of the son rod 820 and the mother rod 810, the spring bead 843 is pressed to disengage from one of the through holes 844. After the son rod 820 is pulled and the position is adjusted, the spring bead 843 is inserted into the corresponding through hole 844 again to complete the position adjustment.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
