Description

Technical Field

[0001] This invention belongs to the field of precast concrete connection technology, and particularly relates to an assembled precast concrete connection component. Background Technology

[0002] In the field of construction engineering, prefabricated concrete structures are widely used due to their advantages such as high construction efficiency and good environmental protection. The connection quality of prefabricated concrete components directly determines the stability and safety of the overall structure. Prefabricated concrete connection components refer to special components or node structures used in prefabricated concrete structure systems to reliably connect prefabricated concrete components and transfer loads and internal forces.

[0003] For example, Chinese patent document (CN205975585U) discloses a novel precast concrete connection component; it includes a socket assembly and an insertion assembly. The socket assembly includes a large nut, inside which are arranged a spring, an integrated claw, and a middle nut arranged sequentially from the inside to the outside. An annular washer is fitted on the outside of the middle nut. The insertion assembly includes a round-headed insertion rod, which includes a round plug, a neck, and a connecting rod. The connection between the round plug and the neck is a concave annular groove. The inner wall shape of the outer end of the integrated claw matches the shape of the annular groove. The round plug passes through the middle nut and is inserted into the integrated claw. The inner end of the integrated claw abuts against the spring.

[0004] However, during use, the structure is designed with the axial force of the round-headed plug and the claw point or line contact structure as its core design goal, resulting in poor radial fixing effect. This may cause local deformation or stress concentration of the component under bending load, which in turn leads to loosening of the connection. Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to address the problem that existing technologies, which focus solely on axial force in their design, have poor radial fixing effects and may lead to local deformation, stress concentration, and loosening of connections in components under bending loads. Therefore, this invention proposes a prefabricated concrete connection component.

[0045] Steel bars are installed on the opposite sides of both the precast pile sleeve and the precast pile head.

[0046] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0047] 1. In this invention, the precast pile head is fixed by the arc-shaped block and the limiting block, auxiliary card block, limiting card groove and auxiliary card groove, so as to achieve dual fixation of the component in the axial and radial directions, forming a multi-point and multi-directional radial locking structure. This not only greatly improves the firmness of the connection part, but also significantly improves the overall pull-out resistance, compressive resistance and lateral displacement resistance. It effectively resists the complex stress generated by the superstructure load, foundation settlement and other factors during the use of the building, avoids the risk of loosening, displacement or even separation of the connection part, and enables the connection part to withstand greater pull-out force and shear force, ensuring the integrity and stability of the structure and meeting the stress requirements of the precast building structure.

[0048] 2. In this invention, the annular cone block enters the conical groove inside the annular seal. Utilizing the squeezing action of the conical structure, uniform radial pressure is generated on the lip portion of the inner circumference of the annular seal. This causes the lip portion to undergo elastic deformation towards the outer circumference of the precast pile head, ultimately resulting in a tight fit with the outer wall of the precast pile head. This eliminates connection gaps, prevents external rainwater, moisture, dust, and other impurities from entering the connection area, and avoids cracking and weathering of concrete components due to moisture intrusion. This significantly improves the sealing and durability of the connection between the precast pile head and the precast pile sleeve, extending the service life of the entire connection component.

[0049] 3. In this invention, the precise guidance and positioning of the guide component quickly limits and calibrates the relative installation positions of the precast pile head and the precast pile sleeve, effectively eliminating the error of manual docking, ensuring that the central axis of the precast pile head and the precast pile sleeve coincides, significantly improving the docking accuracy, avoiding the impact of installation position deviation on the subsequent connection effect, and simplifying the docking operation process, greatly enhancing the guidance and portability during the component installation and connection process.

[0050] 4. In this invention, the overall compactness of the product is improved through the coordinated cooperation of the connecting components, sealing components and guiding components. It does not require complicated construction equipment and processes, and is simple and easy to operate. The product is applicable to different construction scenarios of precast concrete components of various specifications. It can meet the connection requirements of different parts and different stress requirements in prefabricated buildings, and effectively improves the practicality of the product.

The other end of the connecting rod 603 is provided with an arc block 605 and a limiting block 606, which are used to quickly improve the radial and axial fixing effect between the precast pile sleeve 1 and the precast pile head 2.

[0066] The sealing component 7 is located on the bottom inside the precast pile sleeve 1 and is used to quickly ensure the sealing of the connection between the precast pile sleeve 1 and the precast pile head 2.

[0067] The guide component 8 is set at the bottom of the precast pile sleeve 1 and is used to guide and limit the position of the precast pile head 2 during the installation process;

[0068] Connection component 6 also includes:

[0069] Multiple first springs 602 are arranged in a circular array inside the precast pile sleeve 1, and the first springs 602 are sleeved on the outer periphery of the connecting rod 603. The two sides of the first springs 602 are fixedly connected to one side of the first cone block 604 and the inner wall of the precast pile sleeve 1, respectively. The connecting rod 603 is slidably connected inside the precast pile sleeve 1. The mounting cavity 601 is connected to the cone cavity 9.

[0070] Multiple arc-shaped blocks 605 are fixedly connected to elastic layers 608 on both sides;

[0071] Multiple sets of auxiliary blocks 607 are respectively set on the inner periphery of multiple arc blocks 605. Each set of auxiliary blocks 607 consists of multiple auxiliary blocks 607, and the multiple auxiliary blocks 607 are symmetrically distributed with the limiting block 606 as the center.

[0072] Multiple limiting slots 609 are arranged in a circular array on the top side inside the precast pile head 2, and the limiting block 606 is slidably connected inside the limiting slots 609;

[0073] Multiple sets of auxiliary slots 610 are arranged in a circular array on the top side inside the precast pile head 2. Each set of auxiliary slots 610 consists of multiple auxiliary slots 610. The multiple auxiliary slots 610 are symmetrically distributed with the limiting slot 609 as the center. The auxiliary block 607 is slidably connected inside the auxiliary slot 610.

[0074] Also includes:

[0075] Steel bars 3 are installed on the opposite sides of both the precast pile sleeve 1 and the precast pile head 2.

[0076] Specific implementation method: First, multiple precast pile sleeves 1 and multiple precast pile heads 2 are respectively fixed at equal intervals to the ends of the two precast concrete components to be connected using multiple matching steel rods 3. During installation, ensure that the steel rods 3 on both sides of the precast pile sleeves 1 and precast pile heads 2 are fully embedded inside the components, and that the surface of the precast concrete component is level with the end faces of the precast pile sleeves 1 and precast pile heads 2. This avoids subsequent docking deviations due to end face tilting, providing a basic guarantee for subsequent precise connection. Then, gently place the precast concrete component with the precast pile heads 2... Slowly hoist the precast pile head 2 to the component corresponding to the precast pile sleeve 1, aligning the side of the precast pile head 2 away from the steel bar 3 with the bottom opening of the precast pile sleeve 1, and gradually insert it into the precast pile sleeve 1. At this time, the conical structure of the conical cavity 9 can guide the precast pile head 2 to enter in the correct direction, avoiding initial misalignment. After the alignment is in place, the worker rotates the sleeve 4 using external tools. As the sleeve 4 moves downward on the surface of the precast pile sleeve 1, the inclined surface 5 on the bottom side inside the precast pile sleeve 1 will first align with the first conical block 604 and the first spring. 602 is squeezed, causing the first cone block 604 to move the arc block 605, the limiting block 606, and the auxiliary locking block 607 through the connecting rod 603. At this time, the inner circumference of the arc block 605 will fit and clamp the surface of the precast pile head 2 to ensure the axial fixation effect of the precast pile head 2. During this process, the limiting block 606 and the auxiliary locking block 607 will accurately enter the limiting slot 609 and the auxiliary slot 610, further ensuring the radial fixation effect of the precast pile head 2, realizing the dual fixation of the component in both axial and radial directions, forming a multi-point, multi-directional radial locking structure. This dual fixation structure greatly improves the firmness of the connection part, significantly improves the overall pull-out resistance, compressive resistance, and lateral displacement resistance, effectively resists the complex stress generated by the superstructure load and foundation settlement during the use of the building, avoids the risk of loosening, displacement, or even separation of the connection part, and enables the connection part to withstand greater pull-out force and shear force, ensuring the integrity and stability of the structure and meeting the stress requirements of the precast building structure.

[0077] Sealing assembly 7 includes:

[0078] An annular seal 701 is provided inside the precast pile sleeve 1, and a tapered groove 709 is provided inside the annular seal 701. The inner circumferential side of the annular seal 701 is provided with a lip-shaped part 710.

[0079] An annular cone 702 is disposed inside a conical groove 709, and a plurality of connecting blocks 703 are arranged in a circular array on the top circumference of the annular cone 702;

[0080] The second cone block 705 is fixedly connected to the connecting block 703 on the side away from the annular cone block 702, and both the second cone block 705 and the connecting block 703 are slidably connected inside the precast pile sleeve 1.

[0081] Multiple sets of second springs 704 are arranged in a circular array inside the precast pile sleeve 1. Each set of second springs 704 consists of two second springs 704. The two second springs 704 are symmetrically distributed with the connecting block 703 as the center, and the two sides of the second springs 704 are fixedly connected to one side of the second cone block 705 and the inner wall of the precast pile sleeve 1, respectively.

[0082] The third cone block 706 is fitted onto the outer surface of the second cone block 705;

[0083] A rectangular block 707 is fixedly connected on one side to the outer wall of the third cone block 706 away from the second cone block 705, and a fourth cone block 708 is fixedly connected on the other side of the rectangular block 707. The rectangular block 707, the fourth cone block 708 and the third cone block 706 are all slidably connected inside the precast pile sleeve 1.

[0084] Detailed Implementation: As the sleeve 4 continues to move downwards, the inclined surface 5 of the sleeve 4 will press against the fourth cone block 708, and through the fourth cone block 708, the rectangular block 707, and the third cone block 706, it will press against the second cone block 705 and the second spring 704, causing the second cone block 705 to move through the connecting block 703 and drive the annular cone block 702 to move. As the annular cone block 702 moves, it will enter the conical groove 709 inside the annular seal 701. Utilizing the pressing action of the conical structure, a uniform radial pressure is generated on the lip portion 710 on the inner circumference of the annular seal 701, causing the lip portion 702 to... The precast pile head 2 undergoes elastic deformation on its outer periphery, eventually fitting tightly against the outer wall of the precast pile head 2, eliminating connection gaps and preventing external rainwater, moisture, dust, and other impurities from entering the connection area. This avoids cracking and weathering of the concrete component due to moisture intrusion, significantly improving the sealing and durability of the connection between the precast pile head 2 and the precast pile sleeve 1, and extending the service life of the entire connection component. The annular seal 701 is set as an elastic element. After the annular seal 701 is sealed, concrete or resin can be filled at the installation position between the precast pile sleeve 1 and the precast pile head 2 as needed to further improve the connection stability of the product.

[0085] Guide component 8 includes:

[0086] An annular plate 801 is installed below the precast pile sleeve 1, and the annular plate 801 is fixedly connected to the outer periphery of the precast pile head 2.

[0087] Multiple guide rods 802 are arranged in a circular array on the top of the annular plate 801;

[0088] Multiple guide grooves 803 are arranged in a circular array on the bottom side inside the precast pile sleeve 1, and guide rods 802 are slidably connected inside the guide grooves 801.

[0089] Detailed implementation: When the precast pile head 2 enters the precast pile sleeve 1 to a certain depth, the guide rod 802 enters the guide groove 803 to quickly limit the installation position of the precast pile head 2 and the precast pile sleeve 1. Through the sliding cooperation between the guide rod 802 and the guide groove 803, the relative installation position of the precast pile head 2 and the precast pile sleeve 1 is quickly limited and calibrated. This guiding and limiting structure effectively eliminates the error of manual docking, ensures that the central axis of the precast pile head 2 and the precast pile sleeve 1 coincides, significantly improves the docking accuracy, avoids the impact of installation position deviation on the subsequent connection effect, simplifies the docking operation process, and greatly enhances the guidance and portability in the component installation and connection process.

[0090] Working principle: In use, multiple precast pile sleeves 1 and multiple precast pile heads 2 are first fixed at equal intervals to the ends of the two precast concrete components to be connected using multiple matching steel rods 3. During installation, ensure that the steel rods 3 on both sides of the precast pile sleeves 1 and precast pile heads 2 are fully embedded inside the components, and that the surface of the precast concrete component is level with the end faces of the precast pile sleeves 1 and precast pile heads 2. This avoids subsequent docking deviations caused by end face tilting, providing a basic guarantee for accurate subsequent connection. The precast concrete component with precast pile heads 2 is then slowly hoisted to the corresponding component with precast pile sleeves 1. Beside the precast pile head 2, align the side of the precast pile head 2 away from the steel rod 3 with the bottom opening of the precast pile sleeve 1, and gradually insert it into the precast pile sleeve 1. At this time, the conical structure of the conical cavity 9 can guide the precast pile head 2 to enter in the correct direction. When the precast pile head 2 enters the precast pile sleeve 1 to a certain depth, the guide rod 802 is inserted into the guide groove 803 to quickly limit the installation position of the precast pile head 2 and the precast pile sleeve 1. Through the sliding cooperation between the guide rod 802 and the guide groove 803, the relative installation position of the precast pile head 2 and the precast pile sleeve 1 is quickly limited and calibrated.

[0091] After the connection is in place, the staff rotates the sleeve 4 using external tools. As the sleeve 4 moves downward on the surface of the precast pile sleeve 1, the inclined surface 5 on the bottom side of the precast pile sleeve 1 will first squeeze the first cone block 604 and the first spring 602. This causes the first cone block 604 to move the arc block 605, the limiting block 606 and the auxiliary locking block 607 through the connecting rod 603. At this time, the inner circumference of the arc block 605 will fit and clamp the surface of the precast pile head 2 to ensure the axial fixation effect of the precast pile head 2. During this process, the limiting block 606 and the auxiliary locking block 607 will accurately enter the limiting slot 609 and the auxiliary slot 610, further ensuring the radial fixation effect of the precast pile head 2, and realizing the dual fixation of the component in both the axial and radial directions.

[0092] As the sleeve 4 continues to move downwards, the inclined surface 5 of the sleeve 4 will squeeze the fourth cone block 708, and through the fourth cone block 708, the rectangular block 707 and the third cone block 706, squeeze the second cone block 705 and the second spring 704, causing the second cone block 705 to drive the annular cone block 702 to move through the connecting block 703. As the annular cone block 702 moves, it will enter the conical groove 709 inside the annular seal 701. Utilizing the squeezing action of the conical structure, a uniform radial pressure is generated on the lip portion 710 on the inner circumference of the annular seal 701, causing the lip portion 710 to undergo elastic deformation towards the outer circumference of the precast pile head 2, ultimately fitting tightly against the outer wall of the precast pile head 2, making it convenient to use.
