Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and specifically discloses a connection mechanism for prefabricated steel structure buildings. Background Technology

[0002] With the development of industrialized construction, prefabricated steel structure buildings are widely used in industrial plants, public buildings, and high-rise residential buildings due to their advantages such as fast construction speed, reliable structure, energy saving, and environmental protection. The connection of the steel structure is a crucial link in prefabricated construction, directly affecting the stability of the overall structure and construction efficiency. Existing steel structure connections typically employ welding, ordinary bolt connections, or simple plug-in methods. These connections require significant manual positioning and temporary fixing during installation, limiting installation accuracy and speed. Especially in complex site environments or when high-altitude operations are required, traditional connection methods often suffer from installation difficulties, poor connection accuracy, and inability to quickly adjust and reinforce, failing to meet the requirements of prefabricated buildings for high efficiency, reusability, and ease of maintenance. An existing fire-resistant steel structure building (publication number: CN212224190U) has at least the following drawbacks: 1. Existing steel structure connections are mostly simple bolted or welded connections, with joints typically being flat butt joints. They lack dedicated mounting slots and columns for precise guidance and positioning, and also lack adaptive expansion and contraction mechanisms such as limit columns and spring-loaded telescopic columns. During installation, the positions of the connectors require repeated manual adjustments, resulting in low efficiency and poor positioning accuracy. Due to the lack of spring-loaded buffers and limit devices, there are issues with large assembly gaps or uneven stress distribution during connection, which can easily lead to loosening or stress concentration during subsequent use, affecting the structural lifespan.

[0003] 2. Existing traditional connection structures often rely solely on main connecting bolts for initial fixation after installation, lacking pre-drilled limiting and fixing holes for subsequent adjustments and reinforcement. When the building structure experiences minor displacement due to load changes, thermal expansion and contraction, or prolonged use, secondary reinforcement and adjustment cannot be performed using these pre-drilled holes, leading to difficulties in maintenance and reinforcement work. If subsequent reinforcement is required, construction personnel must either drill new holes or weld, increasing construction difficulty and costs, and also affecting on-site safety and project schedule. Utility Model Content

[0004] The main purpose of this utility model is to provide a prefabricated steel structure building connection mechanism, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a prefabricated steel structure building connection mechanism, including a support column, an installation groove, a spring telescopic column, and a reserved limiting and fixing hole. A connecting block is installed on the side of the support column, and a reserved limiting and fixing hole is provided on the connecting block. An installation groove is provided on the inner side of the connecting block for installing the connecting column. A limiting column is provided on the front side of the connecting column, and a spring telescopic column is installed inside the limiting column.

[0006] Preferably, an installation post is provided in front of the connecting post.

[0007] Preferably, the mounting post is used in conjunction with the mounting groove.

[0008] Preferably, the limiting post and the spring telescopic post cooperate to extend and retract.

[0009] Preferably, the connecting block and the support column are fixed together by bolts.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model achieves self-guiding positioning and adaptive expansion and contraction of the connecting components by setting an installation groove and connecting block on the side of the support column, and adding an installation column, a limiting column, and a built-in spring telescopic column in front of the connecting column. The connecting column can automatically align with the installation groove and the installation column, reducing repeated manual adjustments and significantly improving installation efficiency and positioning accuracy. The cooperation between the limiting column and the spring telescopic column provides elastic buffering and limiting effects, automatically absorbing connection gaps, avoiding uneven stress, improving the stability and durability of the overall structure, and reducing loosening and stress concentration after long-term use.

[0011] 2. This utility model features pre-drilled limiting and fixing holes on the connecting block, allowing for secondary reinforcement of the connection structure after initial installation. When the building structure experiences minor displacement due to load changes, thermal expansion and contraction, or long-term use, construction personnel can directly use the pre-drilled holes to add bolts for re-fixation, eliminating the need for drilling or welding, making maintenance and reinforcement more convenient and efficient. This design reduces construction costs and safety risks, shortens the reinforcement period, and significantly improves the adaptability and subsequent maintenance performance of the connection structure.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0016] Please see Figure 1-4 This utility model provides a technical solution: A prefabricated steel structure building connection mechanism includes a support column, a mounting groove, a spring telescopic column, and a reserved limiting and fixing hole. A connecting block is installed on the side of the support column, and the reserved limiting and fixing hole is provided on the connecting block. The mounting groove is provided on the inner side of the connecting block for installing the connecting column. A limiting column is provided on the front side of the connecting column, and a spring telescopic column is installed inside the limiting column. An installation column is provided in front of the connecting column. The installation column and the mounting groove are used together. The limiting column and the spring telescopic column cooperate to extend and retract. The connecting block and the support column are fixed with bolts.

[0017] It should be noted that, regarding self-guiding positioning and adaptive extension: This utility model achieves the guiding function of the connecting column during installation by interlocking the connecting block fixed on the side of the support column with the installation column fixed at the front end of the connecting column.

[0018] During installation, the mounting post at the front end of the connecting post is inserted into the mounting groove on the side of the support post. The mounting post and the mounting groove form a sliding guide, ensuring that the connecting post can be smoothly pushed along the predetermined position, achieving automatic alignment and reducing repeated manual adjustments.

[0019] The limiting post is set on the front side of the connecting post, and a spring telescopic post is installed inside it. When the connecting post and the connecting block are in contact, the limiting post and the inner wall of the connecting block form a stop. The spring telescopic post provides elastic pre-compression during the connection process, which can automatically absorb the connection gap and keep the connection surface tightly in contact.

[0020] The combination of this limiting post and spring telescopic post effectively prevents the connection parts from loosening due to manufacturing and installation tolerances, avoids displacement or stress concentration after long-term stress, and thus improves the stability and durability of the overall structure.

[0021] Regarding the secondary reinforcement function: This utility model has multiple pre-drilled limiting and fixing holes on the connecting block, and the connecting block is fixed to the support column by bolts during installation.

[0022] During initial assembly, the connecting block is basically fixed by bolts, and the connecting column is quickly installed through the guiding fit of the mounting groove and the mounting column, and the limiting fit of the limiting column and the spring telescopic column.

[0023] If slight displacement occurs during use due to load changes, thermal expansion and contraction, or long-term use, construction personnel can use the pre-reserved limiting and fixing holes on the connecting block to directly install new bolts to further strengthen the fixing force between the connecting block and the support column.

[0024] Since the structure of the pre-reserved limiting and fixing holes and connecting blocks is prefabricated in the factory, there is no need to re-drill holes or perform welding operations on site, which not only improves the efficiency of maintenance and reinforcement, but also avoids the safety hazards caused by secondary construction.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
