Description

Technical Field

[0001] This utility model relates to the field of building assembly technology, specifically to an insert-type layered assembly self-locking connector and a beam-column or wall panel connection structure. Background Technology

[0002] In the era of prefabricated construction, energy conservation and environmental protection during construction, significantly reduced on-site construction periods, lower on-site project management difficulty, and reduced reliance on the technical skills of on-site installation workers are becoming increasingly important trends. Utilizing the industrialization and productization of building materials to simplify on-site construction of prefabricated buildings can effectively address many problems in my country's construction industry, such as low levels of industrialization, long construction cycles, and labor shortages. This represents an effective way for the construction industry to transform and upgrade.

[0003] Connection nodes, as critical points in structural building systems, directly impact the overall structural safety through their mechanical properties. The ease of node installation determines the overall project schedule; therefore, resolving connection issues at structural nodes becomes a key challenge for project progress. Conventional structural connection nodes in domestic engineering projects exhibit the following shortcomings:

[0004] The fully welded joints of the beam-column flanges and webs in steel structures require on-site welding, which makes it difficult to guarantee weld quality, demands high technical skills from welders, and necessitates additional weld quality inspection procedures, severely impacting project speed. While these welded joints exhibit high stiffness, they also have poor ductility, making them unsuitable for seismic loads and prone to brittle failure.

[0005] The fully bolted joint of the beam-column flange and web of the steel structure: The steel column is equipped with a section of factory-welded cantilever beam, and then the beam and column are rigidly connected by full bolt beam splicing. This connection method increases the number of component connection nodes, and the number of steel columns with cantilever beams that can be transported at one time is limited, which greatly increases the transportation cost.

[0006] The steel structure beam-column bolted-welded hybrid connection node: flange welding and web hinge. This node still requires a lot of on-site welding, with many procedures, which greatly reduces the construction speed.

[0007] The protruding bolts of the steel structure beams and columns affect the installation of prefabricated wall panels and floor slabs, requiring cutting and other processes.

[0008] On-site splicing of steel columns generally adopts a combination of butt welding or bolt welding, but both methods have problems such as high construction difficulty and slow construction speed in on-site construction.

[0009] Precast floor slabs are typically connected by lapping the pre-reserved steel bars at the slab ends, followed by pouring concrete, or by using connectors and grouting material. This method has the drawbacks of long construction periods and wet work on site.

[0010] Containerized building structures typically connect the containers at the corners using corner fittings and bolts. However, if the connection point is in the middle, there may be insufficient space to make the connection impossible. In such cases, alternative connection methods must be adopted.

[0011] Precast wall panels are typically connected using methods such as fixed sleeves with grouting, steel reinforcement grouting lap splices, welding, and bolting. However, all of these methods involve subsequent grouting and curing, leading to long construction periods and wet work on site. Construction can also be difficult in confined spaces.

[0012] To address these issues, we offer plug-in layered self-locking connectors and beam / column or wall panel connection structures. Utility Model Content

[0013] The purpose of this utility model is to overcome the shortcomings of the prior art by providing an insert-type layered assembly self-locking connector and a beam-column or wall panel connection structure to solve the technical problems of the prior art, such as complex operation and small operating space at the node installation point, which make it difficult to achieve convenient and effective rapid installation.

[0014] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0015] The insert-type layered assembly self-locking connector includes two symmetrically distributed bundles of devices, with a connecting threaded rod installed between the two bundles, and each bundle includes:

[0016] A fixed sleeve has an installation cavity inside, and the installation cavity is provided with a tapered surface. An internal thread is provided on the inner wall of the end of the fixed sleeve; a connecting threaded rod is installed in the installation cavity.

[0017] The end nut has an external thread that is threaded to the fixed sleeve and is fitted onto the end of the connecting threaded rod.

[0018] A tapered toothed assembly, comprising multiple toothed plates, each toothed plate having teeth that movably abut against a connecting threaded rod;

[0019] An elastic open steel ring, which surrounds and connects multiple toothed plates in a conical shape and is fitted onto the connecting threaded rod;

[0020] The clamping spring has one end abutting against the conical tooth assembly and the other end abutting against the end nut.

[0021] In a further technical solution, two sets of fixed sleeves are symmetrically distributed, and a conical surface is provided on the opposite side of the fixed sleeves;

[0022] Two sets of conical surfaces are arranged in pairs; the inner diameter of the two sets of conical surfaces tapers in the middle and expands towards the end nut at both ends.

[0023] In a further technical solution, the end nut is threaded onto the fixed sleeve, and the end is located outside the mounting cavity;

[0024] When the end nut is fully installed inside the fixed sleeve, it abuts against the tightening spring, causing the conical tooth assembly to be pressed and move towards the connection between the two sets of fixed sleeves.

[0025] In a further technical solution, the outer surface of the toothed plate is a folded surface, and a reserved groove is opened inside, which is connected to an elastic open steel ring.

[0026] The thickness of the toothed plate gradually decreases toward the side away from the corresponding end nut.

[0027] A beam-column structure for an insert-type layered self-locking connector includes a frame column, a frame beam, and a node connection box. The node connection box is cross-shaped and has a beam assembly bundle 1 installed on its four sides and a column assembly bundle 1 installed in the middle. Both the beam assembly bundle 1 and the column assembly bundle 1 have the same structure as the assembly bundle.

[0028] A beam assembly bundle two is installed on the frame beam, and a beam threaded rod is installed between the beam assembly bundle one and the beam assembly bundle two.

[0029] A second column assembly is installed at one end of the frame column relative to the node connection box. A threaded rod is installed between the second column assembly and the first column assembly. The threaded rod and the threaded rod are the same as the aforementioned connecting threaded rod.

[0030] In a further technical solution, frame columns are symmetrically installed on the top and bottom of the node connection box, and frame beams are installed on all four sides; there is an upper inclined plate on the side of the frame beam opposite to the node connection box, and a beam device bundle one is installed through the upper inclined plate; a lower inclined plate is provided on the node connection box, and a beam device bundle two is installed through the lower inclined plate, with the upper and lower inclined plates fitted together.

[0031] The wall panel structure of the insert-type layered self-locking connector includes shear wall one and shear wall two. Self-locking device bundle one is prefabricated and installed in shear wall one, and self-locking device bundle two is prefabricated and installed in shear wall two. Self-locking device bundle one and self-locking device bundle two are connected by a high-strength bolt rod. Self-locking device bundle one and self-locking device bundle two have the same structure as the aforementioned device bundle.

[0032] Compared with existing technologies, it has the following advantages:

[0033] This invention utilizes a spring-loaded conical tooth assembly to propel the toothed plate forward along the conical cylinder, causing it to engage with the connecting threaded rod. During on-site installation, the self-locking connector of this invention first inserts a high-strength bolt into the self-locking device bundle already welded to the lower component. Then, the upper component is lifted, and the self-locking device bundle is aligned with the connecting threaded rod, allowing gravity to complete the connection. This operation facilitates on-site construction and significantly accelerates the installation process while ensuring structural safety.

[0034] The connection node of this utility model is a self-locking connection. Multiple sets of self-locking connector bundles can be used on each side to achieve the connection goal as needed. Since no bolt connection is required on-site, the spacing can be reduced compared to traditional bolt connections. Furthermore, by optimizing and rationally arranging the self-locking connectors, the strength of the connection part is higher than the strength of the component itself, which can meet the basic principle of structural design such as strong nodes and weak members.

[0035] This utility model's self-locking connector modularizes each component, connecting them on-site using high-strength bolts to form a unified whole. This achieves the goal of integrating independent components into a cohesive unit. The connected beams, columns, wall panels, and floor slabs are all straight or planar components, significantly reducing transportation space and effectively saving on transportation costs.

Detailed Implementation

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0056] In practical implementation, this application includes at least a self-locking connector and a connecting threaded rod, wherein the self-locking connector comprises: a fixing sleeve, an end nut, a tapered tooth assembly (composed of multiple fan-shaped teeth), an elastic open steel ring, and a tightening spring.

[0057] Example 1

[0058] like Figure 1-7 As shown, this is one embodiment of the present invention: an insert-type layered assembly self-locking connector, comprising a device bundle, on which a connecting threaded rod 6 is mounted; the device bundle includes:

[0059] A fixed sleeve 5 has an installation cavity inside, and a tapered surface 51 is provided inside the installation cavity. An internal thread is provided on the inner wall of the end of the fixed sleeve 5. A connecting threaded rod 6 is installed in the installation cavity.

[0060] End nut 1, with external threads on the outside, is threadedly connected to the fixed sleeve 5 and is sleeved on the end of the connecting threaded rod 6;

[0061] The conical tooth assembly 4 includes multiple toothed pieces 41, each toothed piece 41 having teeth and movably abutting against the connecting threaded rod 6.

[0062] The elastic open steel ring 3 is a conical ring that surrounds and connects multiple toothed pieces 41 and is sleeved on the connecting threaded rod 6.

[0063] The clamping spring 2 has one end abutting against the conical tooth assembly 4, as shown in the reference. Figure 7 As shown. The other end abuts against end nut 1.

[0064] This embodiment uses a single-unit assembly. A tapered toothed component and a clamping spring are installed inside the fixed sleeve. The end is fitted with an end nut to abut against the clamping spring. (See reference...) Figure 4As shown, the tightening spring abuts against the conical tooth assembly downwards, and is pressed inwards by the conical surface inside the fixed sleeve to engage with the connecting threaded rod. Multiple toothed plates are coaxially installed inside the fixed sleeve via elastic open steel rings 3. The connecting threaded rod is inserted from the side of the fixed sleeve that is not the end nut, driving the teeth inwards and into the conical tooth assembly, compressing the tightening spring, so that the connecting threaded rod can be inserted into the end nut groove inside the fixed sleeve. The tightening spring uses its elasticity to push the teeth outwards, ultimately making the teeth tightly engage with the high-strength bolt rod. If the high-strength bolt rod is subjected to an outward pulling force, the tightening spring pushes the teeth outwards even further, making them engage with the high-strength bolt rod more and more tightly.

[0065] refer to Figure 5 and 6 One side has a fixed sleeve pre-embedded in the building, and the other side is open. When not in use, it is blocked with a plug to prevent foreign objects from entering. When in use, the connecting threaded rod 6 is inserted upward into the fixed sleeve to complete the top fixation of the connecting threaded rod. The connecting threaded rod can be connected to other components downward, achieving the effect of pre-embedded connecting threaded rod, and there are no problems such as misalignment.

[0066] Example 2

[0067] like Figure 8 As shown, this is one embodiment of the present invention. Based on embodiment 1, a pad is installed on the end face of the fixed sleeve 5 away from the port die. The pad serves as a working surface, ensuring that the connection is in a flat state. A nut is installed at the bottom for fixation. This fixed sleeve provides top reinforcement and locking, effectively connecting to the outside.

[0068] Example 3

[0069] Please see Figure 9-12 This utility model provides a technical solution: an insert-type layered assembly self-locking connector, comprising two symmetrically distributed device bundles, with a connecting threaded rod 6 installed between the two device bundles, and each device bundle comprising:

[0070] A fixed sleeve 5 has an installation cavity inside, and a tapered surface 51 is provided inside the installation cavity. An internal thread is provided on the inner wall of the end of the fixed sleeve 5. A connecting threaded rod 6 is installed in the installation cavity.

[0071] End nut 1, with external threads on the outside, is threadedly connected to the fixed sleeve 5 and is sleeved on the end of the connecting threaded rod 6;

[0072] The conical tooth assembly 4 includes multiple toothed pieces 41, each toothed piece 41 having teeth and movably abutting against the connecting threaded rod 6.

[0073] The elastic open steel ring 3 is a conical ring that surrounds and connects multiple toothed pieces 41 and is sleeved on the connecting threaded rod 6.

[0074] The clamping spring 2 has one end abutting against the conical tooth assembly 4 and the other end abutting against the end nut 1.

[0075] Combination Figure 9 and Figure 12 As shown, two sets of fixed sleeves 5 are symmetrically distributed, and each fixed sleeve 5 has a conical surface 51 on its opposite side; the two sets of conical surfaces 51 are arranged in pairs; the inner diameter of the two sets of conical surfaces 51 tapers in the middle and expands towards the end nut 1 at both ends. The end nut 1 is threaded onto the fixed sleeve 5, and its end is located outside the mounting cavity;

[0076] When the end nut 1 is fully installed inside the fixed sleeve 5, it abuts against the top spring 2, causing the conical tooth assembly 4 to be pressed and move towards the connection of the two sets of fixed sleeves 5.

[0077] like Figure 10 and Figure 11 As shown, the toothed plate 41 has an outer angled surface and an inner reserved groove 42, which is connected to the elastic open steel ring 3. The thickness of the toothed plate 41 gradually decreases towards the side away from the corresponding end nut 1.

[0078] The principle of this self-locking connector is as follows: A conical shape is formed by the conical teeth around an elastic open steel ring, which is then placed inside a fixed sleeve. A tightening spring is then placed into the fixed sleeve, and finally, the end nut is tightened to complete the installation of the self-locking connector. The threaded connecting rod is inserted through the opening of the fixed sleeve, causing the teeth to move inward and compressing the tightening spring. This allows the threaded connecting rod to be inserted into the groove of the end nut inside the fixed sleeve. The tightening spring uses its elasticity to push the teeth outward, ultimately causing the teeth to tightly engage with the high-strength bolt. If the high-strength bolt is subjected to outward pulling force, the tightening spring pushes the teeth further outward, making the engagement with the high-strength bolt even tighter.

[0079] The self-locking connector of this utility model is used by pre-embedding a set of self-locking connectors at the ends of each component. During on-site installation, the connecting threaded rod is first inserted into the device bundle at the end of the first component that has been installed. When the second component is adjusted and positioned, the device bundle of the second component is aligned with the connecting threaded rod that was just inserted into the first component and then dropped to lock it, thus completing the installation.

[0080] This utility model's self-locking connector allows all components to be manufactured through factory casting. During on-site installation, the high-strength bolt is first inserted into the self-locking device bundle already welded to the lower component. Then, the upper component is lifted, and the self-locking device bundle is aligned with the connecting threaded rod, allowing gravity to complete the connection. This operation facilitates on-site construction and significantly accelerates the installation progress while ensuring structural safety.

[0081] The connection node of this utility model is a self-locking connection. Multiple sets of self-locking connector bundles can be used on each side to achieve the connection goal as needed. Since no bolt connection is required on-site, the spacing can be reduced compared to traditional bolt connections. Furthermore, by optimizing and rationally arranging the self-locking connectors, the strength of the connection part is higher than the strength of the component itself, which can meet the basic principle of structural design such as strong nodes and weak members.

[0082] This utility model's self-locking connector modularizes individual components, which are then connected on-site using high-strength bolts. This achieves the goal of integrating independent components into a cohesive whole. The connected beams, columns, wall panels, and floor slabs are all straight or planar components, significantly reducing transportation space and effectively saving transportation costs. For an increasing number of overseas EPC projects, especially prefabricated steel structure projects that are manufactured domestically and then transported overseas for installation, utilizing this new type of connector will greatly enhance a company's market competitiveness.

[0083] Example 4

[0084] like Figure 13 and 14 As shown, another embodiment of this utility model is described. In conjunction with Embodiment 1, the self-locking connectors are assembled in layers at the nodes of the beam-column steel structure. Multiple self-locking connectors can be bundled together according to the calculated stress requirements. The self-locking connectors are respectively placed at the ends of the frame beams, the ends of the frame columns, and at the corresponding positions of the node connection boxes.

[0085] A beam-column structure for an insert-type layered self-locking connector includes a frame column 7, a frame beam 8, and a node connection box 9. The node connection box 9 is cross-shaped and has beam device bundles 12 installed on its four sides and a column device bundle 16 installed in the middle. The beam device bundles 12 and the column device bundles 16 are the same as the device bundle structure.

[0086] A beam assembly bundle 2 13 is installed on the frame beam 8, and a beam threaded rod 15 is installed between the beam assembly bundle 12 and the beam assembly bundle 2 13; in this embodiment, the end nut is removed, and the column assembly bundle and the beam assembly bundle are directly used to replace the fixing sleeve.

[0087] A column assembly bundle 2 11 is installed at one end of the frame column 7 relative to the node connection box 9. A column threaded rod 14 is installed between the column assembly bundle 2 11 and the column assembly bundle 16. The column threaded rod 14 and the beam threaded rod 15 have the same structure as the connecting threaded rod 6.

[0088] Frame columns 7 are symmetrically installed on the top and bottom of the node connection box 9, and frame beams 8 are installed on all four sides; on the side of the frame beam 8 opposite to the node connection box 9, there is an upper inclined plate 81, and a beam device bundle 12 is installed through the upper inclined plate 81; a lower inclined plate 91 is provided on the node connection box 9, and a beam device bundle 13 is installed through the lower inclined plate 91, and the upper inclined plate 81 and the lower inclined plate 91 are fitted together.

[0089] First, install the frame column 7 in place, then insert the column threaded rod 14. Connect the node connection box 9 into a whole through the column threaded rod 14. Then insert the beam threaded rod 15 into the node connection box 9. Hoist the frame beam 8 in sequence and insert the beam threaded rod 15 through the beam device bundle 2 13 to complete the installation of the frame beam 8. After the frame beam 8 is installed, insert the upper column threaded rod 14 into the node connection box 9. Finally, insert the column threaded rod 14 through the column device bundle 2 11 to complete the installation of the upper frame column. Repeat the above operations until all node connections are completed. This utility model's self-locking connector beam-column connection steel structure node is suitable for column splicing of all column cross-section forms, such as steel structure I-beams, box-type columns, and precast concrete columns.

[0090] Example 5

[0091] like Figure 15 As shown, the layered assembly of self-locking connectors at the nodes of shear walls mainly consists of upper and lower shear walls 21 and 27, and self-locking connectors. Multiple self-locking connectors can be bundled together according to the calculated stress requirements. The bundles of self-locking connectors are respectively placed at the upper and lower ends of the two sets of shear walls to be connected.

[0092] The wall panel structure of the insert-type layered self-locking connector includes shear wall one 21 and shear wall two 27. Self-locking device bundle one 22 is prefabricated within shear wall one 21, and self-locking device bundle two 28 is prefabricated within shear wall two 27. High-strength bolt rods 23 connect self-locking device bundle one 22 and self-locking device bundle two 28. The structure of self-locking device bundle one 22 and self-locking device bundle two 28 is the same as that of the device bundle in Example 1. In this example, the end nuts are removed, and the self-locking device bundle directly replaces the fixing sleeve in Example 1, while maintaining the same internal structure.

[0093] First, install the lower shear wall 27 into position. Insert the high-strength bolt 23 into the self-locking device bundle 28 pre-embedded in the shear wall 27. Then, hoist the upper shear wall 21, which is equipped with the self-locking device bundle 22, and insert the high-strength bolt 23 to complete the shear wall connection. This self-locking connector is well-suited for connecting precast concrete wall panels and floor slabs, significantly shortening the construction cycle and reducing construction difficulty.

[0094] Example 6

[0095] like Figure 16 As shown, the layered assembly of self-locking connectors connects the frame columns and column nodes, mainly consisting of upper and lower frame columns and self-locking connectors. Multiple self-locking connectors can be bundled together according to the calculated stress requirements. The self-locking connectors are respectively placed at the upper end of the lower frame column and the lower end of the upper frame column.

[0096] First, install the lower frame column 7 into position and insert the column threaded rod 14. Then, hoist the upper frame column 7, which has the column device bundle 2 11, and insert it into the already installed column threaded rod 14 to complete the column-to-column connection installation. In this embodiment, the end nuts are removed, and the device bundle is used directly to replace the fixing sleeve.

[0097] Example 7

[0098] like Figure 17 As shown, the layered assembly of self-locking connectors is used in floor slab node connections. The nodes are composed of self-locking connectors, and multiple self-locking connectors can be bundled together according to the calculated stress requirements. The self-locking connectors include a pre-embedded frame device bundle 19 and a precast floor slab device bundle 20, which are pre-embedded in the floor slab frame beams and the four bottom and four top corners of the floor slab, respectively. Depending on the structural scheme, the floor slab can be a precast thick concrete slab or a lightweight floor slab with a frame.

[0099] First, the floor slab bottom frame is welded together, and frame device bundles 19 are pre-embedded at the four corners. After the frame is assembled, the floor slab is laid and forms an integral part with the bottom frame. During installation, the floor slab connecting threaded rod is first inserted into the pre-embedded frame device bundles 19 on the floor slab frame beam 17, and then the floor slab is directly hoisted as a whole. The prefabricated floor slab device bundles 20 on the prefabricated floor slab frame 18 are aligned with the floor slab connecting threaded rods and directly inserted to lock the connection and complete the installation. The pre-embedded frame device bundles 19 and prefabricated floor slab device bundles 20 have the same structure as the device bundles in Example 1. In this example, the end nuts are removed, and the device bundles are directly used to replace the fixing sleeves.

[0100] Example 8

[0101] like Figure 18As shown, the layered assembly self-locking connector is used in the connection of container buildings. The connection consists of self-locking connectors, and multiple self-locking connectors can be bundled together according to the calculated force requirements. The self-locking connectors include a first self-locking device bundle 25 and a second self-locking device bundle 29, which are pre-embedded in the four corners of the top and bottom of the container body, respectively. In this embodiment, the end nuts are removed, and the device bundles are used directly to replace the fixing sleeves.

[0102] like Figure 11 As shown, the lower container 24 is first installed in place. Then, the container connecting threaded rod 26 is inserted into the container self-locking device bundle 25 at the four corners of the top of the container. Next, the upper container 24 is hoisted, and the bottom of the upper container is connected to the container self-locking device bundle 29. Aligning the container connecting threaded rod, it is directly inserted to lock the connection and complete the installation. In this embodiment, the self-locking connector 25 includes all the structures except the connecting threaded rod in embodiment 1, replacing the connecting threaded rod with the container connecting threaded rod 26 in this embodiment. This self-locking connector is very suitable for connecting container buildings, avoiding problems such as the inability to install bolts due to limited space or spatial layout, greatly improving construction speed.
