Description

Technical Field

[0001] This utility model relates to the field of flexible connection technology for steel structures, specifically a flexible connection node for prefabricated steel structures. Background Technology

[0002] In the field of prefabricated steel structure buildings, connection nodes are the core components that ensure the stability and safety of the overall structure. Their design rationality directly affects construction efficiency, seismic performance and subsequent maintenance costs. With the advancement of building industrialization, prefabricated steel structures are increasingly widely used due to their advantages such as short construction cycle and green environmental protection. The industry has put forward higher requirements for the ease of installation and reliability of connection nodes. In particular, in the process of node assembly, accurate and efficient positioning has become one of the key links to improve construction efficiency.

[0003] A patent document with publication number CN107675801A discloses a prefabricated steel structure beam-column connection node and its connection method, which aims to solve the problem of poor seismic performance of existing nodes. The prefabricated steel structure beam-column connection node is used to connect steel beams and steel columns. A connection part is located at the end of the steel beam, and a set of plate spring assemblies are respectively installed in the mounting grooves on both sides of the steel beam. A concrete block formed by grouting is placed in the grouting space between the grouting groove and the inner wall of the rectangular steel pipe. A transition connector composed of a steel plate and a rectangular steel pipe is used, wherein the steel plate is fixed to the steel beam by high-strength bolts, and the rectangular steel pipe forms an insertion part, into which the connection part is inserted to form a partial overlap. Anchor holes are provided on the plate spring assemblies, partitions, and steel columns, and steel cables pass through the anchor holes and are fixed at both ends to the steel column and steel beam. In non-earthquake conditions, this node is a rigid connection; in earthquake conditions, it forms a flexible, movable connection, which can avoid the brittle fracture problem caused by rigid nodes.

[0004] However, the above-mentioned solutions and existing technologies lack quick positioning components during installation. In actual construction, workers need to repeatedly adjust the relative positions between the main structure, the transverse structure and the fixing plate to ensure that each component is aligned and subsequently fixed. This not only increases the complexity of manual operation but also prolongs the assembly time of a single node, making it difficult to fully meet the efficient and precise construction requirements of prefabricated buildings.

[0005] Therefore, this utility model proposes a prefabricated steel structure flexible connection node to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a flexible connection node for prefabricated steel structures to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated steel structure flexible connection node, including a main structure, a fixing plate, and a transverse structure, wherein a fixing plate is provided on the lower side of the main structure, a second fixing plate is provided on the upper side of the main structure, and the transverse structure is installed at both ends of the main structure; The main structure is provided with a positioning component, a snap-fit ​​component, and a buffer component. The positioning component is disposed on the fixed plate, the snap-fit ​​component is disposed on the upper side of the transverse structure, and the buffer component is disposed on the snap-fit ​​component.

[0008] Preferably, the positioning block in the positioning component is fixedly installed at the bottom end of the fixed plate, and the positioning block is slidably engaged with the positioning groove.

[0009] Preferably, the positioning groove in the positioning component is fixedly disposed on the second fixing plate, and the second fixing plate and the fixing plate are fixedly installed by screws.

[0010] Preferably, the first snap-fit ​​groove in the snap-fit ​​assembly is disposed at both ends of the main structure, and a snap-fit ​​hook is snap-fitted and installed in the first snap-fit ​​groove, and the snap-fit ​​hook is disposed on one side of the transverse structure.

[0011] Preferably, the second snap-fit ​​groove in the snap-fit ​​assembly is disposed below the first snap-fit ​​groove, and a snap-fit ​​protrusion is slidably snapped into the second snap-fit ​​groove, the snap-fit ​​protrusion being disposed below the snap-fit ​​hook.

[0012] Preferably, the buffer pad in the buffer assembly is sleeved on the side of the transverse structure, which is fixedly installed on both ends of the main structure by screws.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting positioning components, snap-fit ​​components, and buffer components in the connection nodes, the problems of inconvenient installation and positioning and low assembly efficiency in existing technologies are effectively solved. Among them, the positioning component, with the sliding snap-fit ​​cooperation of the positioning block and the positioning groove, can quickly and accurately align the fixed plate and the second fixed plate without the need for workers to repeatedly adjust the position, significantly reducing the complexity of manual operation and shortening the assembly time of a single node; the snap-fit ​​component, through the double snap-fit ​​structure of the first snap-fit ​​groove and snap-fit ​​hook, and the second snap-fit ​​groove and snap-fit ​​protrusion, enhances the stability of the connection between the main structure and the transverse structure, while simplifying the assembly process of the two; the buffer pad of the buffer component can buffer the impact force when the transverse structure is connected to the main structure, reducing the hard friction wear between components. The three work together to improve the installation efficiency and docking accuracy of the prefabricated steel structure connection nodes, and ensure the reliability and service life of the node connection, making it more suitable for the efficient and precise construction needs of prefabricated buildings.

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0017] Example 1: Please refer to Figures 1 to 2 A prefabricated steel structure flexible connection node includes a main structure 1, a fixing plate 2, and a transverse structure 3. The fixing plate 2 is provided on the lower side of the main structure 1, and a second fixing plate 4 is provided on the upper side of the main structure 1. The transverse structure 3 is installed at both ends of the main structure 1. The main structure 1 is provided with a positioning component, a snap-fit ​​component, and a buffer component. The positioning component is set on the fixed plate 2, the snap-fit ​​component is set on the upper side of the transverse structure 3, and the buffer component is set on the snap-fit ​​component.

[0018] The positioning block 401 in the positioning assembly is fixedly installed at the bottom end of the fixed plate 2, and the positioning block 401 is slidably engaged with the positioning groove 402.

[0019] The positioning groove 402 in the positioning assembly is fixedly mounted on the second fixing plate 4, and the second fixing plate 4 and the fixing plate 2 are fixedly installed by screws.

[0020] In use, first, firmly install the second fixing plate 4 in the preset reference position. Then, hold the main structure 1 and align it downwards, so that the positioning block 401 at the bottom end of the fixing plate 2 on the lower side of one main structure 1 is aligned with the positioning groove 402 on the upper middle fixing plate 4 of the other second main structure 1. Slowly push the fixing plate 2 along the length of the positioning groove 402 until the positioning block 401 is completely inserted into the positioning groove 402. At this time, the fixing plate 2 and the second fixing plate 4 are precisely aligned without the need for repeated fine-tuning. After alignment, use screws of appropriate specifications to pass through the reserved mounting holes of the second fixing plate 4 and the fixing plate 2 and tighten them to complete the fixed assembly of the positioning component. This greatly reduces the intensity of manual operation and lays a precise and stable foundation for the subsequent installation of the transverse structure 3.

[0021] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The first snap-fit ​​groove 501 in the snap-fit ​​assembly is located at both ends of the main structure 1. A snap-fit ​​hook 502 is snap-fitted into the first snap-fit ​​groove 501. The snap-fit ​​hook 502 is located on one side of the transverse structure 3.

[0022] The second snap-fit ​​groove 503 in the snap-fit ​​assembly is located below the first snap-fit ​​groove 501. A snap-fit ​​protrusion 504 is slidably snapped into the second snap-fit ​​groove 503. The snap-fit ​​protrusion 504 is located below the snap-fit ​​hook 502.

[0023] In use, after the positioning components are assembled, take the transverse structure 3 and adjust its angle so that the snap hook 502 on one side of the transverse structure 3 is at the same horizontal height as the first snap groove 501 at both ends of the main structure 1. At the same time, ensure that the snap protrusion 504 on the lower side of the snap hook 502 is aligned with the second snap groove 503 on the lower side of the first snap groove 501. Hold the transverse structure 3 with both hands and push it towards the main structure 1. When the snap hook 502 contacts the edge of the first snap groove 501, slightly adjust the force to make the snap hook 502 snap into the first snap groove 501. Simultaneously, the snap protrusion 504 also slides into the second snap groove 503 and forms a sliding snap. The double snap structure instantly completes the initial positioning of the transverse structure 3 and the main structure 1, effectively preventing the transverse structure 3 from shifting up or down or left or right during the subsequent fixing process. Compared with the pre-positioning steps of traditional bolt connection, the assembly process is simpler and the positioning accuracy is significantly improved.

[0024] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The buffer pad 601 in the buffer assembly is fitted onto the side of the transverse structure 3, and the transverse structure 3 is fixedly installed on both ends of the main structure 1 by screws.

[0025] Before initial snap-fitting of the components, check whether the buffer pad 601 on the side of the transverse structure 3 is in the preset position. Ensure that the buffer pad 601 completely covers the connection end between the transverse structure 3 and the main structure 1. It can buffer the impact force between the transverse structure 3 and the main structure 1 during the subsequent fixing process, avoid scratches or deformation of metal parts due to hard contact, and reduce friction loss. After confirming that the buffer pad 601 is installed correctly, pass the high-strength screw through the corresponding mounting holes of the transverse structure 3 and the main structure 1, and tighten the screw according to the preset torque value to complete the final fixing of the transverse structure 3 and the main structure 1. This further ensures the reliability of the connection node and extends the service life of the entire steel structure.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
