Description

Technical Field

[0001] This utility model relates to the field of steel structure engineering technology, and in particular to the field of steel structure corridor lifting technology, specifically referring to a lifting structure for the upper part of a large-span steel structure corridor. Background Technology

[0002] Steel structure engineering is a structure mainly made of steel, consisting of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets, and it is one of the main types of building structures.

[0003] Large steel structure components (such as space frames and trusses) are widely used in modern construction engineering. These components are typically large and heavy, posing challenges to installation. As building structures increasingly demand higher safety, precision, and efficiency in steel structure installation, and as steel structure buildings develop towards higher heights, larger spans, and irregular shapes (such as large stadiums, super high-rise buildings, and irregularly shaped curtain walls), safety standards are rising, requiring more reliable safety guarantees and improved construction efficiency. This is driving the development of rapid installation technologies. Traditional hoisting techniques have revealed a series of bottlenecks, prompting steel structure lifting supports to iterate towards intelligence, high stability, and environmental adaptability. At the same time, steel structure lifting supports must also meet requirements such as reducing overall costs, improving construction efficiency, better controlling quality and precision, and ensuring comprehensive safe construction.

When the diagonal brace 10 is an I-beam diagonal brace, the leftmost and rightmost upper front stiffening plates 11 are located below the front end of the lifting equipment mounting beam 2 and connected to the front end of the lifting equipment mounting beam 2, respectively located above the left and right flange plates of the right end of the diagonal brace 10. The two middle upper front stiffening plates 11 are not located below the front end of the lifting equipment mounting beam 2 but are connected to the front end of the lifting equipment mounting beam 2. The leftmost and rightmost upper rear stiffening plates 12 are located below the rear end of the lifting equipment mounting beam 2 and connected to the rear end of the lifting equipment mounting beam 2, respectively located above the left and right flange plates of the right end of the diagonal brace 10. The two middle upper rear stiffening plates 12 are not located below the rear end of the lifting equipment mounting beam 2 but are connected to the rear end of the lifting equipment mounting beam 2. In other words, when there are multiple upper front stiffening plates 11 and multiple upper rear stiffening plates 12, the shapes of the multiple upper front stiffening plates 11 may not be exactly the same, and the shapes of the multiple upper rear stiffening plates 12 may not be exactly the same.

[0052] The superstructure of the large-span steel structure corridor may also include any other suitable components; please refer to [link / reference needed]. Figure 1 As shown in a specific embodiment of this utility model, the upper lifting structure of the large-span steel structure corridor further includes an upper front steel column stiffening plate 17 and an upper rear steel column stiffening plate (not shown in the figure). The upper front steel column stiffening plate 17 and the upper rear steel column stiffening plate are both horizontally arranged and spaced apart from each other, and are both located on the left side of the left end of the diagonal brace 10. The upper front steel column stiffening plate 17 and the upper rear steel column stiffening plate are respectively located in front of and behind the web of the steel column 101 and are both connected to the web of the steel column 101. The upper front steel column stiffening plate 17 and the upper rear steel column stiffening plate are also both located between the left flange plate and the right flange plate of the steel column 101 and are both connected to the left flange plate and the right flange plate of the steel column 101, respectively. When the diagonal brace 10 is an I-beam diagonal brace, the upper front steel column stiffening plate 17 and the upper rear steel column stiffening plate are both located to the left of the left flange plate at the left end of the diagonal brace 10.

[0053] The superstructure of the large-span steel structure corridor may also include any other suitable components; please refer to [link / reference needed]. Figure 1 As shown in a specific embodiment of this utility model, the upper lifting structure of the large-span steel structure corridor further includes a lower front steel column stiffening plate 18 and a lower rear steel column stiffening plate (not shown in the figure). The lower front steel column stiffening plate 18 and the lower rear steel column stiffening plate are both horizontally arranged and spaced apart from each other, and are both located on the left side of the lower flange plate of the lower steel beam 103. The lower front steel column stiffening plate 18 and the lower rear steel column stiffening plate are respectively located in front of and behind the web of the steel column 101 and are both connected to the web of the steel column 101. The lower front steel column stiffening plate 18 and the lower rear steel column stiffening plate are also both located between the left flange plate and the right flange plate of the steel column 101 and are both connected to the left flange plate and the right flange plate of the steel column 101, respectively.

[0054] Before lifting the large-span steel structure corridor, hoisting equipment is used to hoist the lifting equipment installation beam 2 onto the upper steel beam 102. The middle part of the lifting equipment installation beam 2 is then installed on the upper flange plate of the upper steel beam 102. The front lifting equipment 4 and the rear lifting equipment 5 are then installed on the front and rear ends of the lifting equipment beam, respectively, to ensure their stability. Afterwards, the steel strand guide frame 3 is installed on the middle part of the lifting equipment installation beam 2. Because the lifting of the large-span steel structure corridor is a highly dangerous and complex project, local reinforcement is provided to ensure the location of the lifting points. To ensure strength and stability, and to guarantee that the structure can safely withstand the massive concentrated loads generated during hoisting in this critical area, preventing local buckling or deformation, support plates and stiffening plates are used at appropriate locations. Specifically, the lower flange of the upper steel beam 102 is widened by connecting the upper front support plate 6 and the upper rear support plate 7 to the front and rear of the lower flange of the upper steel beam 102, respectively. Similarly, the upper flange of the lower steel beam 103 is widened by connecting the lower front support plate 8 and the lower rear support plate 9 to the front and rear of the upper flange of the lower steel beam 103, respectively. Furthermore, the lower front support plate 8 and the lower rear support plate 9 are also located at the steel column 101. The upper and lower steel beams 102 are connected to steel columns 101 at both ends. Diagonal braces 10 are installed at the right end of the lower flange plate, upper front support plate 6, and upper rear support plate 7 of the upper steel beam 102. Diagonal braces 10 are installed at the left end of the upper flange plate, lower front support plate 8, and lower rear support plate 9 of the lower steel beam 103, as well as on the right side of the steel columns 101. This effectively transfers the large concentrated load to the connection between the steel columns 101 and the lower steel beam 103 of the main steel structure 1 at the lower left. An upper front stiffening plate 11 is installed between the upper flange plate, web plate, lower flange plate, and upper front support plate 6 of the upper steel beam 102. A front stiffening plate 11 is installed between the upper flange plate, web plate, lower flange plate, and upper front support plate 6 of the upper steel beam 102. An upper rear stiffening plate 12 is installed between the web, lower flange plate, and upper rear support plate 7, which greatly increases the local stiffness and bending resistance of the web at the lifting point and effectively prevents buckling instability of the web under concentrated load. This greatly improves the overall stability and compressive strength of the web under lifting load. A lower front stiffening plate 13 is installed between the lower front support plate 8, the upper flange plate, web, and lower flange plate of the lower steel beam 103, and a lower rear stiffening plate 14 is installed between the lower rear support plate 9, the upper flange plate, web, and lower flange plate of the lower steel beam 103, providing more reliable and safer measures for lifting.

[0055] During the lifting of the large-span steel structure corridor, multiple steel strands connected to the front lifting equipment 4 and the rear lifting equipment 5 are respectively wound around the steel strand guide frame 3 and then connected to the large-span steel structure corridor. The large-span steel structure corridor is lifted by the front lifting equipment 4 and the rear lifting equipment 5.

[0056] Therefore, this utility model employs a lifting equipment installation beam mounted on the upper steel beam of the main steel structure. The front lifting equipment, rear lifting equipment, and steel strand guide frame are situated on the lifting equipment installation beam. Support plates are installed at the front and rear of the lower flange of the upper steel beam for widening, and support plates are installed at the front and rear of the upper flange of the lower steel beam for widening. The upper steel beam transmits force to the lower steel beam and the steel columns of the main steel structure through diagonal bracing. This design can be used as the upper lifting structure for large-span steel structure corridors during the construction and use of large steel structure buildings such as steel structure stadiums and large-span trusses. It ensures that the structure is adaptable to steel structure lifting conditions, meets high-precision installation requirements, and solves the shortcomings of existing large-span steel structure corridors in terms of safe construction, quality control, and construction efficiency during high-altitude installation. This ensures the structural safety and stability of large steel structure corridors during construction.

[0057] In summary, the upper lifting structure of the large-span steel structure corridor of this utility model can ensure the safety and stability of the large-span steel structure corridor during construction, guarantee installation accuracy, improve construction efficiency, and is ingeniously designed, simple in structure, easy to manufacture, and low in manufacturing cost, making it suitable for large-scale promotion and application.

[0058] Therefore, it is evident that the objective of this utility model has been fully and effectively achieved. The function and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the stated principles, any modifications can be made to the implementation methods. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
