Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, specifically to a reinforcement structure for prefabricated buildings based on anchor piles and its application method. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. Anchor piles are mechanical facilities used to reinforce the foundations of prefabricated buildings.

[0003] For example, the utility model patent document with publication number CN203393732U discloses an anchor pile structure. This utility model consists of a pile body and an anchor pile cap. A steel bracket is set on the anchor pile cap and fixed to the anchor pile cap by anchor rods. A reaction beam is horizontally set in the middle of the steel bracket, and a jack is installed at the bottom of the reaction beam. The jack is connected to the pile body. This utility model features a reasonable design, low construction cost, low energy consumption, weak vibration, low noise, and low pollution. However, it uses aiming rods for positioning, typically four in total. A drawback is that if the number of rotations of the four aiming rods is inconsistent when manually rotated, the connection tightness between the steel support and the aiming rod mounting platform will vary, resulting in different stress distributions. This could cause the aiming rod pile to tilt during operation, affecting construction quality. Furthermore, after the jack pushes the pile downwards, a chain is needed to move the reaction beam downwards. However, the lack of a structure to position the reaction beam during the initial jacking operation may prevent the jack from performing subsequent work. The most common method for positioning the reaction beam is to insert iron pins into the through holes in the aiming rod mounting platform, which is time-consuming and labor-intensive.

[0004] Therefore, there is an urgent need for a new type of prefabricated building reinforcement structure based on anchor piles to solve the above problems. Summary of the Invention

[0005] 1. The problem to be solved

[0006] The purpose of this invention is to solve the problems of difficult positioning, inconvenient construction operation, and poor structural stability of existing anchor pile reinforcement devices. It provides a reinforcement structure for prefabricated buildings based on anchor piles. This structure is simple in design, stable in installation, and convenient to use. In addition, this invention also provides a method for using the reinforcement structure, which has the advantages of good positioning effect, saving time and effort, and effectively solving the above-mentioned shortcomings of existing anchor pile reinforcement devices.

[0007] 2. Technical Solution

[0008] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0009] This invention discloses a prefabricated building reinforcement structure based on anchor piles, comprising an anchor pile assembly. The anchor pile assembly includes a reaction frame, a reaction beam, and a foundation. The reaction frame is erected directly above the pile hole, and each of its two legs is detachably connected to the foundation via a separate reinforcement component. The two ends of the reaction beam are slidably mounted on the reaction frame, and a jack is provided at the bottom of the reaction beam. Positioning components are also provided at both ends of the reaction beam, and multiple spaced protrusions are correspondingly provided on the reaction frame.

[0010] As a further improvement of the present invention, the reinforcement component includes a mounting plate and a second motor. The mounting plate is fixedly connected to the reaction frame, and the mounting plate is symmetrically provided with a second outer shell at both ends. The second outer shell penetrates through and extends out of the outer side of the mounting plate and engages with a slot on the support platform.

[0011] The positioning component includes a wedge block, which is slidably mounted on both ends of the reaction beam via a spring telescopic member and engages between the protrusions of the reaction frame.

[0012] As a further improvement of the present invention, a latching block is retractably installed inside the outer shell 2, one end of the latching block extends through to the outside of the outer shell 2 and engages with the latching slot 2 opened on the inner side wall of the latching slot 1.

[0013] A housing is fixedly installed on the reaction beam. A motor is fixedly connected to the inner cavity of the housing. The output shaft of the motor passes through the inner cavity of the reaction beam and is fixedly connected to a threaded rod. The other end of the threaded rod is rotatably connected to the reaction beam. A threaded block is threadedly connected to the surface of the threaded rod. Both sides of the bottom of the threaded block extend to the outside of the reaction beam and are fixedly connected to the positioning frame.

[0014] The positioning frame has two symmetrically arranged working cavities inside. Each working cavity is equipped with a spring telescopic component, which includes a spring and a connecting block. One end of the spring is fixedly connected to the inner wall of the working cavity, and the other end is fixedly connected to the connecting block. One side of the connecting block extends through to the outside of the working cavity and is fixedly connected to a wedge-shaped block of the positioning component.

[0015] As a further improvement of the present invention, a second motor is fixedly installed in the inner cavity of the second outer shell, and a disk is fixedly connected to the output shaft of the second motor. A movable block is provided around the disk, and the movable block is slidably installed in a groove on the inner side wall of the second outer shell.

[0016] The top of the disc has multiple adjustment holes arranged in a ring. The inner cavity of each adjustment hole is movably connected to a slider. The bottom of the slider is fixedly connected to a locking block. The surface of the outer shell has a sliding hole, and the locking block slides in cooperation with the sliding hole.

[0017] The wedge block includes wedge block one and wedge block two, which are fixedly connected by a connecting block. The connecting block is fixedly connected to the linkage block. The inclined surfaces of wedge block one and wedge block two are staggered and not located on the same side.

[0018] As a further improvement of the present invention, limit grooves are provided at the top and bottom of the inner cavity of the working cavity, and limit blocks are slidably connected to the inner cavity of the limit grooves, and one side of the limit block is fixedly connected to the linkage block.

[0019] As a further improvement of the present invention, guide holes are provided on both sides of the bottom of the reaction beam, and the threaded block and the guide holes form a sliding connection.

[0020] As a further improvement of the present invention, the positioning frame is concave in shape.

[0021] As a further improvement of the present invention, a circular block is fixedly connected to the top of the slider, and the diameter of the circular block is larger than the diameter of the slider.

[0022] As a further improvement of the present invention, it also includes an electric hoist and a mounting frame, wherein the electric hoist is mounted on a reaction frame and the electric hoist and the reaction beam are used in conjunction; the bottom of the reaction beam is fixedly mounted with a mounting frame, and the mounting frame is fixedly connected to a jack.

[0023] The above-mentioned method for using prefabricated building reinforcement structures based on anchor piles includes the following steps:

[0024] Step 1: When using the equipment, place the reaction frame directly above the pile hole and fix it to the bearing platform using the reinforcement components.

[0025] Step 2: Adjust the positioning components. After the reaction beam is slidably adjusted to the working position on the reaction frame, the positioning components will automatically engage and fix it. After fixing, use jacks to perform pile driving operations.

[0026] Step 3: After the installation of a pile is completed, the position of the positioning component is adjusted again. When the reaction beam is moved up to the initial position, the positioning component automatically engages and fixes itself.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] The present invention provides a prefabricated building reinforcement structure based on anchor piles, which has the advantages of stable installation, convenient use, good positioning effect, and time and labor saving. In use, the reinforcement components replace the traditional aiming rods, and the motor replaces manual rotation. This not only saves a lot of manpower and reduces the workload of workers, but also ensures that the four reinforcement components do not tilt when fixed, so that the reaction frame always remains vertical, improving stability and thus improving the construction quality of the reaction frame.

[0029] Secondly, by setting up the positioning components, the reaction beams used at different times can be positioned without affecting their upward or downward movement. This avoids the need to use the method of inserting transmission iron pins into the through holes of the aiming rod mounting platform, which not only saves time and effort but also helps to speed up the construction progress. Therefore, it has good market prospects and is worth promoting. Attached Figure Description

[0044] Example 1

[0045] like Figure 1 As shown in this embodiment, a prefabricated building reinforcement structure based on anchor piles includes an anchor pile assembly. The anchor pile assembly includes a reaction frame 1, a reaction beam 3, and a foundation 7. The reaction frame 1 is erected directly above the pile hole and includes two vertically arranged legs and a crossbeam. The two legs are located on both sides of the pile hole, and each leg is detachably connected to the foundation 7 via a separate reinforcement component. This reinforcement component can employ quick-release locking connectors to achieve rapid fixing and installation of the reaction frame 1 and the foundation 7. By using the reinforcement component, this invention significantly improves the supporting effect of the reaction frame 1, preventing it from tilting during construction and thus avoiding any shortcomings in the construction results.

[0046] The two ends of the reaction beam 3 can be slidably installed on the reaction frame 2, and the lower part of the reaction beam 3 is provided with a jack 5, which is used to apply pressure to the pile to realize the installation of the pile.

[0047] In addition, the reinforcement structure of the present invention also includes an electric hoist 2 and a mounting frame 4. The electric hoist 2 is mounted on the reaction frame 1, and the electric hoist 2 and the reaction beam 3 are used in conjunction. The bottom of the reaction beam 3 is fixedly mounted with the mounting frame 4, and the mounting frame 4 is fixedly connected to the jack 5.

[0048] Furthermore, the reaction beam 3 is equipped with positioning components 16 at both ends, and the reaction frame 1 is provided with multiple spaced protrusions 17. The positioning components 16 are engaged and fixed between two protrusions 17 to position the reaction beam 3, preventing it from moving during construction and causing poor construction quality. In the prior art, anchor bolts are usually used for positioning and anchor piles are used for reinforcement when reinforcing prefabricated buildings. However, using anchor piles for positioning is difficult, time-consuming, and labor-intensive, resulting in poor construction efficiency and high construction costs. This invention designs a detachable reinforcement component to replace the traditional anchor bolt positioning method. Automatic positioning replaces manual positioning, which not only reduces the time required for positioning but also facilitates disassembly later. Furthermore, by setting the positioning components 16 to position the reaction beam 3, the reaction beam 3 can be conveniently positioned without affecting its upward or downward movement.

[0049] The following is in conjunction with the appendix Figure 1-8 Detailed description of the structure and installation method of the reinforcement component and positioning component 16 in this invention:

[0050] Reinforcement components:

[0051] like Figure 1 and Figure 6-8 As shown, the reinforcement assembly includes a mounting plate 6 and a motor 19. The mounting plate 6 is fixedly connected to the reaction frame 1. The mounting plate 6 increases the contact area between the reaction frame 1 and the support platform 7, which helps improve the stability of the reaction frame 1 installation. Meanwhile, as... Figure 1 and Figure 8 As shown, the support legs of the reaction frame 1 are located at the center of the mounting plate 6. Symmetrically arranged at both ends of the mounting plate 6 are outer shells 18, which penetrate and extend beyond the outer side of the mounting plate 6, engaging with the slots 24 on the support platform 7 for fixation. This achieves a detachable and fixed connection between the reaction frame 1 and the support platform 7. Furthermore, the design of two symmetrically arranged outer shells 18 on one side improves the installation stability of the reaction frame 1.

[0052] In addition, as a further improvement to this embodiment, such as Figure 6 and Figure 7As shown, in the reinforcement structure of the present invention, a locking block 23 is retractably installed inside the outer shell 18. One end of the locking block 23 extends through to the outside of the outer shell 18 and engages with the locking groove 25 opened on the inner side wall of the locking groove 24. After the outer shell 18 and the support 7 are engaged and fixed once, the locking block 23 is extended and retracted and then engaged again inside the support 7, realizing a secondary engagement and fixing, which significantly improves the installation stability of the reaction frame 1.

[0053] A further optimized installation method for the aforementioned card block 23 is as follows:

[0054] A motor 19 is fixedly installed inside the inner cavity of the outer casing 18, and the output shaft of the motor 19 is fixedly connected to a disc 20. Figure 7 As shown, the disc 20 is provided with a movable block 31 around its circumference. The movable block 31 is slidably installed in the groove on the inner side wall of the outer shell 28. With the setting of the movable block 31, when the disc 20 rotates, it will drive the movable block 31 to slide in the inner cavity of the groove opened on the inner wall of the outer shell 28, thereby supporting the disc 20 and improving the stability of the disc 20 when it rotates.

[0055] The top of the disk 20 has multiple adjustment holes 21 arranged in a ring. The number of adjustment holes 21 can be determined according to the actual situation. For ease of description, they are referred to as... Figure 7 Taking the quantity as an example, in the reinforcement structure of this invention, the disc 20 is specifically provided with four adjustment holes 21. A slider 22 is movably connected to the inner cavity of each adjustment hole 21. The bottom of the slider 22 is fixedly connected to the locking block 23, and a sliding hole is provided on the surface of the outer shell 18, allowing the locking block 23 to slide in conjunction with the sliding hole. This invention, by rotating the motor 19, drives the disc 20 to rotate. During the sliding process of the slider 22 in the adjustment hole 21, it drives the locking block 23 to move outwards or inwards. By controlling the forward or reverse rotation of the motor, the extension or retraction of the locking block 23 can be effectively controlled, making operation convenient.

[0056] In addition, such as Figure 6 and Figure 7 As shown, a circular block 30 is fixedly connected to the top of the slider 22, and the diameter of the circular block 30 is larger than the diameter of the slider 22. The circular block 30 serves to position the slider 22, thereby preventing the slider 22 from detaching from the disk 20.

[0057] Positioning component 16:

[0058] like Figure 1 and Figure 2-5 As shown, the positioning component 16 includes a wedge block, which is slidably installed at both ends of the reaction beam 3 via a spring telescopic member and engaged between the protrusions 17 of the reaction frame 1.

[0059] Specifically, such as Figure 1 As shown, multiple protrusions 17 are arranged vertically at intervals on the two legs of the reaction frame 1. The protrusions 17 are located on the inner side of the legs and close to the side of the reaction beam 3, thus supporting the reaction beam 3. Figure 2 and Figure 3 As shown, a housing 8 is fixedly installed on the reaction beam 3. A motor 9 is fixedly connected to the inner cavity of the housing 8. The output shaft of the motor 9 passes through the inner cavity of the reaction beam 3 and is fixedly connected to a threaded rod 10. The rear end of the threaded rod 10 is rotatably connected to the reaction beam 3. When the motor 9 rotates, the threaded rod 10 rotates only with the rotation of the motor 9 within the cavity of the reaction beam 3.

[0060] In addition, such as Figure 2 As shown, the surface of the outer casing 8 has heat dissipation holes, and the inner cavity of the heat dissipation holes is filled with heat dissipation mesh 26. The heat dissipation mesh 26 serves to dissipate heat from the inner cavity of the outer casing 8, thereby creating a good temperature environment for the motor 9.

[0061] like Figure 2 As shown, the threaded rod 10 is threadedly connected to a threaded block 11. Both sides of the bottom of the threaded block 11 extend downwards to the outer side of the reaction beam 3 and are fixedly connected to a positioning frame 12 located at the lower part of the reaction beam 3. Furthermore, in this embodiment, guide holes 27 are provided on both sides of the bottom of the reaction beam 3, and the threaded block 11 and the guide holes 27 form a sliding connection. In this embodiment, the threaded block 11 slides within the inner cavity of the guide holes 27 during movement, thereby limiting and guiding the threaded block 11.

[0062] like Figure 3 As shown, the positioning frame 12 is concave in shape, and has two symmetrically arranged working cavities 13 inside. Each working cavity 13 is equipped with a spring telescopic component, which is connected to the wedge block to position the reaction beam 3. Specifically, as shown... Figure 4 and Figure 5 As shown, the spring telescopic component includes a spring 14 and a linkage block 15. One end of the spring 14 is fixedly connected to the inner wall of the working cavity 13, and the other end is fixedly connected to the linkage block 15. One side of the linkage block 15 extends through to the outer side of the working cavity 13 and is fixedly connected to a wedge-shaped block of the positioning component 16.

[0063] More optimized, such as Figure 5As shown, the wedge block of the present invention includes a first wedge block 161 and a second wedge block 163. The first wedge block 161 and the second wedge block 163 are fixedly connected by a connecting block 162, which is fixedly connected to a linkage block 15. The inclined surfaces of the first wedge block 161 and the second wedge block 163 are staggered and not located on the same side. According to the adjustment requirements of the reaction beam 3, the rotation direction of the first motor 9 is adjusted to control the first wedge block 161 and the second wedge block 163 to respectively engage between the protrusions 17, thereby achieving positioning.

[0064] More optimized, such as Figure 4 and Figure 5 As shown, the top and bottom of the working cavity 13 are provided with limiting grooves 28. A limiting block 29 is slidably connected to the inner cavity of the limiting groove 28, and one side of the limiting block 29 is fixedly connected to the linkage block 15. In this embodiment, through the cooperative use of the limiting groove 28 and the limiting block 29, when the linkage block 15 moves, it will drive the limiting block 29 to slide within the inner cavity of the limiting groove 28, thereby guiding the linkage block 15 and improving the stability of its movement.

[0065] The above-mentioned method for using prefabricated building reinforcement structures based on anchor piles includes the following steps:

[0066] Step 1: When using the equipment, place the reaction frame 1 directly above the pile hole and fix it on the pile cap 7 using the reinforcement components.

[0067] When the anchor pile assembly is used, the reaction frame 1 drives the mounting plate 6 to be placed on top of the bearing platform 7. At this time, the outer shell 18 will be located in the inner cavity of the slot 24, which serves to reinforce the reaction frame 1. Then, the motor 19 can be started. The output shaft of the motor 19 drives the disc 20 to rotate. When the disc 20 rotates, it will drive the movable block 31 to rotate on the inner wall of the outer shell 18. This process provides support for the rotation of the disc 20. Due to the position of the adjustment hole 21, when the disc 20 rotates, it can drive the slider 22 to move in the inner cavity of the adjustment hole 21. Then, the slider 22 will drive the locking block 23 to move to the outside of the outer shell 18. When the locking block 23 moves, it will lock into the inner cavity of the slot 25, which serves to reinforce the reaction frame 1 a second time. This achieves the purpose of installing the reaction frame 1 and facilitating the removal of the reaction frame 1 later.

[0068] Step 2: Adjust the positioning component 16. After the reaction beam 3 is slidably adjusted to the working position on the reaction frame 1, the positioning component 16 will automatically engage and fix it. After fixing, use the jack 5 to perform the pile driving operation.

[0069] First, place the pile in the inner cavity of the pile driving hole. Install the electric hoist 2 on the reaction frame 1. Then, install the electric hoist 2 and the reaction beam 3. Finally, install the jack 5 on the mounting frame 4. Use the extension of the bottom end of the jack 5 to move the pile into the inner cavity of the pile driving hole. At this time, the wedge block 161 engages with the protrusion 17, which plays a positioning role for the reaction beam 3. Therefore, the reaction beam 3 will not move upward when the jack 5 is working. After the jack 5 completes one extension, it retracts. At this time, under the weight of the reaction beam 3, the mounting frame 4, and the jack 5, the reaction beam 3... The reaction beam 3 can be moved downwards or manually pushed downwards. The wedge block 161 will drive the connecting block 15 to slide into the inner cavity of the working chamber 13 and squeeze the spring 14, so that the spring 14 is in a contracted state. Then, when the reaction beam 3 drives the bottom end of the jack 5 to contact the pile again, the elastic potential energy of the spring 14 will drive the wedge block 161 to move back to its original position and engage with the protrusion 17. This process plays a role in positioning the reaction beam 3 and preventing the reaction beam 3 from moving upwards. When the reaction beam 3 moves downwards, the chain length displayed by the electric hoist 2 will also be extended.

[0070] Step 3: After the installation of one pile is completed, the position of the positioning component 16 is adjusted again. When the reaction beam 3 is moved up to the initial position, the positioning component 16 automatically engages and fixes itself.

[0071] Specifically, after the installation of a pile is completed, motor 9 is started. The output shaft of motor 9 drives the threaded rod 10 to rotate. When the threaded rod 10 rotates, it drives the threaded block 11 to move forward through the thread on its surface and with the cooperation of the guide hole 27. The threaded block 11 drives the positioning component 16 to move forward through the transmission of the positioning frame 12 and the linkage block 15. At this time, the wedge block 163 engages with the protrusion 17. Then, the electric hoist 2 drives the reaction beam 3 to move upward. When the reaction beam 3 moves upward, it can drive the wedge block 163 to move into the inner cavity of the working chamber 13. The wedge block 163 compresses the spring 14 through the transmission of the linkage block 15. When the reaction beam 3 moves to the appropriate position, the elastic potential energy of the spring 14 can drive the wedge block 163 to engage with the protrusion 17. This achieves the purpose of positioning the reaction beam 3 and preventing the reaction beam 3 from falling. This achieves the purpose of automatically positioning the reaction beam 3, thereby reducing the labor burden of workers.

[0072] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
