Description

Technical Field

[0001] This application relates to the field of connector technology, and more particularly to connector assemblies and prefabricated component assemblies for connecting prefabricated components. Background Technology

[0002] Precast components are formed in a factory and then connected on the construction site to create a complete component that meets design requirements. Traditionally, welding is used to connect precast components. However, welding is greatly affected by weather and human factors, and has drawbacks such as difficulty in ensuring weld quality, high construction difficulty, and susceptibility to corrosion from underground soil. This leads to safety hazards in the connection of precast components. In addition, the overall strength of components connected by welding is relatively weak.

[0003] To address the aforementioned shortcomings, mechanical connectors that require no welding and can be directly plugged in have emerged, enabling precast piles to be installed on-site without welding. For example, patent (publication number CN212835362U) provides an integrated mechanical connector device, including an upper nut, a lower nut, a plug rod, a limiting connecting sleeve, an elastic element, a sealing cylinder, and a clamping cylinder. The plug rod is threaded to the upper nut, the limiting connecting sleeve is threaded to the lower nut, the upper part of the sealing cylinder is threaded to the lower part of the limiting connecting sleeve, the lower part of the sealing cylinder has a limiting platform with a through hole, the elastic element is placed on the limiting platform, the clamping cylinder is placed above the elastic element, and the upper end of the clamping cylinder has a clamping platform to lock the plug rod. However, the numerous parts in this mechanical connector make the installation process cumbersome and slow down construction efficiency.

[0004] Therefore, how to improve the problems of complex connection and installation of precast components and low construction efficiency has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the core of this application is to disclose a connection component to improve the problems of complex connection and installation of prefabricated components and low construction efficiency.

[0006] Another key aspect of this application is the disclosure of a prefabricated component assembly, including the aforementioned connecting components.

[0007] To achieve the objectives of this application, the following technical solution is adopted:

[0008] A connection component, comprising:

[0009] A socket sleeve, which has a insertion cavity;

[0010] A connector, one end of which has a connecting end, and the other end has a variable diameter connector end that can be inserted into a connector cavity;

[0011] The first nut is located inside the insertion cavity;

[0012] The elastic locking element includes at least two elastic locking elements, each elastic locking element is arranged circumferentially along the insertion cavity, and each elastic locking element surrounds to form an insertion channel. The side of each elastic locking element abuts against the first nut. The elastic locking element includes a pushing part and a locking part, and the pushing part axially pushes the locking part to lock the variable diameter insertion end in the reverse direction.

[0013] Optionally, in the above-mentioned connecting assembly, the pushing part is an axially arranged elastic bending piece, and the locking part is integrally formed with the pushing part.

[0014] Optionally, in the above-mentioned connecting assembly, along the direction from the pushing part to the locking part, the elastic locking member gradually tilts toward the central axis of the plug-in member, and each elastic locking member has at least a radial gap with the inner wall of the socket sleeve, the radial gap gradually increasing along the direction from the pushing part to the locking part.

[0015] Optionally, in the above-mentioned connecting assembly, the bottom of the first nut has a locking tapered positioning cavity, and at least part of the two sides of the locking portion of each elastic locking member abut against the cavity wall of the locking tapered positioning cavity and the outer wall of the necked portion of the reducing plug end, respectively.

[0016] Optionally, in the above-mentioned connecting assembly, the minimum diameter of the insertion channel formed by the upper end face of the locking portion of each elastic locking member is greater than the bottom diameter of the variable diameter insertion end, and the maximum diameter of the insertion channel formed by the upper end face of the locking portion of each elastic locking member is less than the maximum diameter of the variable diameter insertion end.

[0017] Optionally, in the above-mentioned connecting assembly, a relief groove is provided inside the socket sleeve. When the connector is inserted into the insertion channel, the relief groove is used to accommodate the locking part that is radially deformed.

[0018] Optionally, in the above-mentioned connecting assembly, the pushing portion of each elastic locking member is connected to the base plate, and the base plate is connected to the socket sleeve; or,

[0019] The pushing part of each elastic locking element is connected to the annular base, and the annular base is connected to the socket sleeve; or,

[0020] The pushing part of each elastic locking element is connected to the socket sleeve through a connecting plate.

[0021] Optionally, in the above-described connecting assembly, the end of the socket sleeve away from the first nut has a snap-fit ​​portion, and the elastic locking member is located above the snap-fit ​​portion; or...

[0022] The end of the socket sleeve away from the first nut has an internal threaded hole, the diameter of which is less than or equal to the diameter of the insertion cavity.

[0023] Optionally, in the above-mentioned connecting assembly, the outer wall of the plug is provided with a second nut, which abuts against the end of the socket sleeve near the first nut.

[0024] A prefabricated component assembly, comprising at least two prefabricated components, wherein the ends of any two adjacent prefabricated components are connected by the aforementioned connecting assembly;

[0025] Each precast component is pre-embedded with a steel reinforcement cage, which includes multiple reinforcing bars arranged in an array. In any two adjacent precast components, at least a portion of the reinforcing bars of one precast component is installed in a socket sleeve, and at least a portion of the reinforcing bars of the other precast component is connected to a connector.

[0026] As can be seen from the above technical solution, the connecting component provided in this application has multiple elastic locking members forming an insertion channel. When the insertion member is inserted into the insertion channel, the pushing part is compressed downwards by a certain distance, causing the locking part to move away from the central axis of the insertion member, allowing the insertion member to pass through the insertion channel. After the insertion member passes through, the elastic locking members reset, causing the two sides of the locking part to abut against the first nut and the insertion member respectively, thereby achieving reverse locking of the insertion member, resulting in good connection strength and high reliability. In addition, when assembling the connecting component, only the elastic locking members and the first nut need to be installed into the socket sleeve, reducing the assembly time on the construction site and improving construction efficiency. After the elastic locking members are installed, the pushing part pushes the locking part against the first nut, making the elastic locking members less prone to tipping over and avoiding problems in the assembly of the connecting component that could affect the docking of prefabricated components.

[0027] The prefabricated component assembly provided in this application includes the aforementioned connecting components, and thus the prefabricated component assembly and the connecting components have the same technical effect. Attached Figure Description

[0045] The core of this application is to disclose a connection component to improve the problems of complex connection and installation of prefabricated components and low construction efficiency.

[0046] Another key aspect of this application is the disclosure of a prefabricated component assembly, including the aforementioned connecting components.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] like Figures 1-9 As shown in the figure, this application discloses a connecting assembly for connecting two prefabricated components 100, including a socket sleeve 10, a plug-in member 20, a first nut 40 and an elastic locking member 30.

[0049] The socket sleeve 10 has a insertion cavity 11. One end of the insertion member 20 has a connecting end 21, and the other end has a variable diameter insertion end 22 that can be inserted into the insertion cavity 11. The connecting end 21 and the variable diameter insertion end 22 are located at the two ends of the axial extension of the socket sleeve 10, respectively. At least two elastic locking members 30 are included, each elastic locking member 30 being circumferentially arranged within the insertion cavity 11 to form an insertion channel 31. A first nut 40 is disposed within the insertion cavity 11, and the side of each elastic locking member 30 abuts against the first nut 40, meaning each elastic locking member 30 is encapsulated within the insertion cavity 11 by the first nut 40. Each elastic locking member 30 includes a pushing part 32 and a locking part 33. The pushing part 32 axially pushes against the locking part 33 to counteract and lock the variable diameter insertion end 22.

[0050] Specifically, such as Figures 1-4 , Figures 7-8 As shown, multiple elastic locking elements 30 surround to form an insertion channel 31. When the insertion member 20 is inserted into the insertion channel 31, the pushing part 32 is compressed downward by a certain distance, thereby causing the locking part 33 of the elastic locking element 30 to move away from the central axis of the insertion member 20, allowing the variable diameter insertion end 22 of the insertion member 20 to pass through. After the variable diameter insertion end 22 has passed through, the elastic locking element 30 returns to its original position. The two sides of the locking part 33 of each elastic locking element 30 abut against the first nut 40 and the insertion member 20 respectively, thereby achieving reverse locking of the insertion member 20. After insertion, each elastic locking element 30 is looped around the variable diameter insertion end 22 of the insertion member 20 and pressed into the insertion cavity 11 by the first nut 40. The first nut 40 and the receiving sleeve 10 are fixed by a threaded connection.

[0051] The connecting component disclosed in this application has good connection strength and high reliability. When assembling the connecting component, only the elastic locking part 30 and the first nut 40 need to be installed into the socket sleeve 10, which can reduce the assembly time on the construction site and improve construction efficiency. After the elastic locking part 30 is installed, it abuts against the first nut 40 by pushing the locking part 33 through the pushing part 32, making the elastic locking part 30 less likely to tip over and avoiding problems in the assembly of the connecting component that may affect the docking of the precast components.

[0052] Furthermore, such as Figures 1-4 , Figures 7-8 As shown, the pushing part 32 is an axially arranged elastic bent piece with a roughly wavy axial cross section. The pushing part 32 can be formed by stacking multiple bent structures to improve the elasticity of the pushing part 32. The locking part 33 is integrally formed at one end of the pushing part 32, and the locking part 33 and the end of the pushing part 32 form a certain angle. The pushing part 32 and the locking part 33 can be formed by bending the same sheet material through a bending process. This method is simple and convenient to produce.

[0053] To improve the locking performance of the connector 20, the number of elastic locking elements 30 can be multiple, and the elastic locking elements 30 are preferably arranged at equal intervals in the circumferential direction, such as... Figure 8 As shown, in this example, the number of elastic locking elements 30 is preferably four, and the size of each elastic locking element 30 is the same. Of course, the number of elastic locking elements 30 can also be two, three, five, six or more, and their size can also be different. There is no specific limitation.

[0054] Furthermore, such as Figures 5-6 As shown, the reducing plug end 22 of the connector 20 is a ball-shaped part with a notch at the bottom, as... Figure 2 As shown, when the connector 20 is not inserted, at least the end portion of the locking portion 33 protrudes from the inner wall of the first nut 40. Along the direction from the pushing portion 32 to the locking portion 33, the elastic locking member 30 gradually tilts towards the central axis of the connector 20; that is, each locking portion 33 gradually approaches the central axis of the connector 20 from its connection with the pushing portion 32, forming a constriction at its end. In its natural state, the radial dimension of the constriction is smaller than the maximum radial dimension of the variable-diameter insertion end 22 of the connector 20. At least a portion of the elastic locking member 30 has a radial gap with the inner wall of the socket sleeve 10. The radial gap gradually increases along the direction from the pushing portion 32 to the locking portion 33. Each elastic locking member 30 is integrally formed into a tower-shaped or conical structure, making the force on the connector 20 more stable when inserted.

[0055] Furthermore, such as Figures 1-4 , Figures 7-8As shown, a locking conical positioning cavity 41 is formed at the bottom of the first nut 40. At least part of the outer wall of the locking part 33 is adapted to the locking conical positioning cavity 41. The plug 20 is inserted into the plugging channel 31. After the pushing part 32 of the elastic locking part 30 is reset and pushes against the locking part 33, at least part of both sides of the locking part 33 abut against the cavity wall of the locking conical positioning cavity 41 and the outer wall of the necking part 23 of the variable diameter plug end, respectively, thereby achieving reverse locking of the plug 20.

[0056] like Figure 2 As shown, when the connector 20 is not inserted, the minimum diameter L1 of the insertion channel 31 formed by the upper end face of the locking portion 33 of each elastic locking member 30 at the insertion port is greater than the bottom diameter L2 of the variable diameter connector 22, thereby ensuring that the variable diameter connector 22 of the connector 20 can at least partially be inserted into the insertion channel 31. Furthermore, as... Figure 3 As shown, the maximum diameter L3 of the insertion channel 31 formed on the upper end face of the locking part 33 of each elastic locking member 30 is smaller than the maximum diameter L4 of the variable diameter insertion end 22. This ensures that when the variable diameter end of the insertion member 20 is inserted, the variable diameter insertion end 22 will abut against the locking part 33 and compress the pushing part 32, so that the locking part 33 can expand radially, allowing the variable diameter insertion end 22 of the insertion member 20 to completely pass through the insertion channel 31.

[0057] Furthermore, such as Figure 3 As shown, the inner wall of the socket sleeve 10 is provided with a relief groove 12 circumferentially below the first nut 40. When the plug 20 is inserted into the plug channel 31, the relief groove 12 is used to accommodate the expanded locking part 33, that is, to accommodate the locking part 33 that has undergone radial deformation. Specifically, when the variable-diameter plug end 22 presses against the locking part 33, the locking part 33 moves into the clearance groove 12, reducing the compression of the pushing part 32, so that the locking part 33 can quickly reset to reversely lock the plug 20, thereby improving the docking efficiency. Furthermore, the sum of the radial thickness of the first nut 40 and the radial groove depth of the clearance groove 12 forms the maximum movable dimension that accommodates the locking part 33 as it expands radially. Compared to the first nut 40 having only a radial thickness that forms the movable dimension required to allow the locking part 33 to expand radially, this solution can reduce the thickness of the first nut 40, thereby reducing the outer diameter of the first nut 40, and thus reducing the radial dimension of the socket sleeve 10 and the pushing part 32 installed in the socket sleeve 10. Under the premise of ensuring connection strength, the overall size of the connector is reduced, the cost is reduced, and the overall structure of the connector is made more compact.

[0058] Furthermore, in order to ensure that the resilient locking element 30 can always remain in an upright state, such as Figures 1-4As shown, the axial bottom of the pushing portion 32 of each elastic locking member 30 is connected to the base plate 34. The base plate 34 is perpendicular to the central axis of the insertion channel 31. The base plate 34 and the pushing portion 32 are preferably integrally formed. The base plate 34 and the socket sleeve 10 are magnetically connected, adhesively connected, or snap-fit ​​connected; or the bottom of the pushing portion 32 of each elastic locking member 30 is connected to the annular base 36, so that each elastic locking member 30 forms an integral structure. Specifically, as shown... Figure 7 As shown, the bottom of each elastic locking element 30 is connected to an annular base 36, which provides support for each elastic locking element 30. The annular base 36 is magnetically, adhesively, or snap-fitted to the socket sleeve 10; or, as... Figure 8 As shown, the axial bottom of the pushing part 32 of each elastic locking member 30 is installed on the socket sleeve 10 through the connecting plate 35. The connecting plate 35 and the socket sleeve 10 are magnetically connected, adhesively connected, or snap-fit ​​connected.

[0059] Furthermore, in some specific embodiments, such as Figure 2 As shown, the insertion channel 31 is provided with an anti-tipping component 50 that abuts against the elastic locking component 30. The anti-tipping component 50 is generally cylindrical in shape and is located at the bottom of the pushing part 32, abutting against the pushing part 32. By providing the anti-tipping component 50, the elastic locking component 30 can be prevented from tipping over towards the central axis of the insertion channel 31 during construction, thus improving the docking quality.

[0060] Furthermore, such as Figures 1-3 As shown, in some specific embodiments, the end of the socket sleeve 10 away from the first nut 40 is provided with a snap-fit ​​portion 13, and the steel bar upsetting head 102 of the precast component 100 can snap into the snap-fit ​​portion 13. The elastic locking member 30 is located above the snap-fit ​​portion 13, that is, the elastic locking member 30 can be placed on the snap-fit ​​portion 13 or on the steel bar upsetting head 102, which is not specifically limited; or, as Figure 4 As shown, the inner wall of the socket sleeve 10 at the end away from the first nut 40 is provided with an internally threaded hole 14. The diameter of the internally threaded hole 14 is less than or equal to the diameter of the insertion cavity 11. The reinforcing bar of the precast component 100 is threadedly connected to the socket sleeve 10. This type of socket sleeve 10 is usually used for assembling the butt joint of the precast component 100. Specifically, when the diameter of the internally threaded hole 14 is less than the diameter of the insertion cavity 11, a stop is formed at the bottom of the socket sleeve 10, and the elastic locking member 30 can be placed on the stop. When the diameter of the internally threaded hole 14 is equal to the diameter of the insertion cavity 11, the elastic locking member 30 is placed on the reinforcing bar of the precast component 100. The specific choice can be made according to the actual situation.

[0061] Furthermore, the precast components 100 typically include precast piles or precast columns, precast beams, precast slabs, and other assembled precast components 100. For precast piles, when two precast piles are joined, the insertion depth of the connector 20 can be controlled because the pile end faces abut. However, for the joining of assembled precast components 100, when two precast components 100 are joined, the reinforcing bars to be joined are exposed outside the two precast components 100. They need to be joined using a connecting assembly before post-casting to form an integral structure. However, if they are directly joined using the connecting assembly in the above embodiment, because the end faces of the two components do not abut, the elastic locking member 30 can only unidirectionally lock the connector 20, and the connector 20 can still continue to be inserted into the connector cavity 11, making the joining of the two precast components 100 unstable after post-casting. Therefore, to solve the above problems, such as... Figures 4-5 As shown, the outer wall of the plug-in 20 is fitted with a second nut 60 that axially abuts against the socket sleeve 10. Specifically, the second nut 60 is pre-fitted onto the outer wall of the plug-in 20 and is threadedly connected to the plug-in 20. After the plug-in 20 is inserted and locked in the opposite direction by the elastic locking member 30, the second nut 60 is rotated to abut against the socket sleeve 10, thereby restricting the further insertion of the plug-in 20 and ensuring the stable connection of the two prefabricated components 100.

[0062] In addition, such as Figure 9 As shown, this application embodiment also provides a prefabricated component assembly, including at least two prefabricated components 100 that are sequentially connected in one direction. When two adjacent prefabricated components 100 are spliced ​​together, the end of one prefabricated component 100 is connected to the end of the other prefabricated component 100 via the connecting component in the above embodiment.

[0063] Specifically, each precast component 100 is pre-embedded with a steel reinforcement cage, which includes multiple reinforcing bars 101 arranged in an array. In any two adjacent precast components 100, at least some of the reinforcing bars 101 in one precast component 100 are installed at one end of a socket sleeve 10, and at least some of the reinforcing bars 101 in the other precast component 100 are connected at one end of an external sleeve 70. The connector 20 is connected to the external sleeve 70. Alternatively, at least some of the reinforcing bars 101 in another precast component 100 may have threaded holes at one end, and the connector 20 may be threaded into the threaded holes. The elastic locking member 30 and the first nut 40 are sequentially arranged in the socket sleeve 10. The stable connection between the two precast components 100 is achieved through the snap-fit ​​engagement between the variable-diameter plug end 22 of the connector 20 and the locking part 33 of the elastic locking member 30.

[0064] In addition, the precast component 100 may be a precast pile, a precast concrete foundation, a precast slab, a precast wall, a precast column, a precast beam, a precast balcony, a precast bay window, a precast staircase, a precast elevator shaft, a precast roof, or a precast terrace, etc., and is not limited here.

[0065] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
