Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a lightweight lifting support for a hangar door truss. Background Technology

[0002] With the rapid development of the national economy, people's demand for air travel is increasing, and airport construction has also developed rapidly, with a continuous increase in the number of newly built airports. Maintenance hangars and painting hangars, as standard supporting facilities for airports, have also been built in large numbers, and the steel structure roof of the hangar is a key part of the entire hangar project. The steel structure roof of the hangar plays a crucial role in ensuring the safety and functionality of the hangar; it must not only bear its own weight but also withstand the influence of various natural environmental factors. Currently, the steel structure roof of the hangar is usually composed of a hall space frame and a gate truss. Due to its structural weight, large span, and high height, the mainstream construction method is to use the "steel space frame in-situ assembly on the ground and overall hydraulic synchronous lifting" technology to complete the construction. When using hydraulic synchronous lifting technology for overall lifting, a special lifting support, i.e., the lifting upper hoisting point, is required to place the hydraulic lifting device and hydraulic pump source system, etc., and to install and operate the equipment. This lifting support is a temporary steel structure. This type of lifting support structure has many components, requiring a large number of assembly processes and welding work during on-site construction. From material procurement and component fabrication to on-site installation and commissioning, each step requires significant manpower and time. Furthermore, precise control of the dimensions and positions of each component is crucial during construction to ensure the stability and safety of the entire lifting support system. Traditional lifting supports for the gate truss location have several significant drawbacks. Due to the large number of structural components, complex on-site assembly procedures, and extensive welding, construction is slow. In tight deadlines, this can impact the entire hangar project's progress. Simultaneously, the large amount of steel used in the lifting supports increases construction costs, making them uneconomical. In addition, traditional lifting supports may collide and interfere with the interlocking members at the gate truss supports, requiring reinforcement after structural unloading, further increasing construction complexity and costs. Utility Model Content

[0003] To improve the problem of collision and interference between the support fitting members and the lifting bracket, this application provides a lightweight lifting bracket for hangar door trusses.

[0004] This application provides a lightweight lifting support for a hangar door truss, employing the following technical solution: A lightweight lifting support for a hangar door truss includes: Support columns, wherein several groups of support columns are spaced apart, and two columns are spaced apart in each group; The column assembly is fixedly installed between two support columns. The column assembly has several sections connected by threads. A lifting beam is fixedly connected above each pair of column assemblies. A hydraulic lifting device is provided on the lifting beam and connected to the lower lifting point to raise the lifting truss. The diagonal brace is inclinedly positioned between the lifting beam and the column assembly.

[0005] By adopting the above technical solution, several sets of spaced support columns, with two columns in each set, are set up to provide basic support for the lifting truss. The column body is composed of several sections connected by threads, which facilitates installation and disassembly and allows for flexible length adjustment according to actual needs. It is fixed between two support columns and connected to the lifting beam above, making the structure more stable. A hydraulic lifting device is set on the lifting beam and connected to the lower lifting point, which can realize the lifting truss rising. The diagonal brace is inclined between the lifting beam and the column body, which further enhances the structural stability of the lifting support and solves the technical problem of collision and interference between the gate truss support insert and the column body. It avoids the need to add braces after unloading the structure. The structure is simple in construction, is a prefabricated structure, is easy to install and disassemble, reduces the amount of steel used in the steel structure, reduces the input of temporary steel structure materials and construction costs, and can be reused to improve the turnover rate.

This meets the lifting requirements of the hangar door truss. Furthermore, this prefabricated structure is simple to construct, easy to install and disassemble, and conducive to on-site construction. At the same time, it optimizes the structural design, reduces the amount of steel used in the steel structure, and reduces the material input and construction costs of temporary steel structures while ensuring structural safety during construction.

This makes the assembly and disassembly of the column assembly and the lifting beam more convenient and facilitates on-site construction.

[0023] The following combination Figures 1 to 3 This application will be described in further detail.

[0024] This application provides a lightweight lifting support for a hangar door truss.

[0025] refer to Figure 1The lifting support structure consists of support columns 1, column groups 4, lifting beams 5, diagonal braces 8, steel embedded parts 2, steel brackets 3, reinforcing steel plates 6, and column stiffeners 7. Several groups of support columns 1 are spaced apart, with two columns in each group. The lifting truss requires several groups of support columns 1 for support. The column groups 4 are fixedly installed between two support columns 1, and the support columns 1 are made of cast concrete. The lifting beams 5 are fixedly connected above every two column groups 4. The diagonal braces 8 are inclined between the lifting beams 5 and the column groups 4, forming a triangular angle. This structure gives the lifting support structure good stability and load-bearing capacity, effectively supporting the lifting truss 15 as it rises, reducing unnecessary components, and lowering steel consumption and cost.

[0026] refer to Figure 2 and Figure 3 The support columns 1 are typically made of reinforced concrete, providing a stable foundation for the entire lifting support system. Their installation must ensure appropriate spacing between each group to accommodate the dimensions and stress requirements of the lifting support system and lifting truss 15. For example, in some large hangars, the spacing of the support columns 1 will be adjusted according to the width of the hangar door and the span of the lifting truss 15. Besides reinforced concrete, the support columns 1 can also be made of high-strength steel, as long as the load-bearing requirements are met.

[0027] refer to Figure 1 The column assembly 4 includes a first column 401, a second column 402, and a third column 403. The second column 402 is located between the first column 401 and the third column 403, and several second columns 402 can be added between them. The first column 401 is fixedly connected to both sides of the lifting beam 5, and the third column 403 is fixedly connected to the lower part of the steel bracket 3. The fixed connection can be welding or bolting. These columns are generally made of round steel pipes, which have good compressive and bending resistance. The column assembly 4 is connected by threads, which facilitates installation and disassembly and improves construction efficiency. For example, in actual construction, the columns can be pre-assembled on the ground and then hoisted to the designated position as a whole. If the truss height is not ideal after lifting, a second column 402 can be added between the first column 401 and the second column 403 to achieve the desired truss height. In special circumstances, the lifting support can also use flange connections or welding connections, but threaded connections are more advantageous in terms of reusability.

[0028] refer to Figure 2 and Figure 3The lifting beam 5 adopts a box-section member, which provides a large load-bearing area and high strength. Reinforcing steel plates 6 are fixedly connected to the upper and lower parts of the lifting beam 5, and steel strand through holes 560 are provided. The reinforcing steel plates 6 enhance the strength of the lifting beam 5 at the steel strand through holes 560, preventing local deformation during lifting. The steel strand through holes 560 are for the steel strands 10 to pass through, allowing the hydraulic lifter 9 to connect to the lower lifting point via the steel strands 10. The lower lifting point is a temporary ball lifting point 11. The upper lifting point is formed by the lifting beam and the hydraulic lifter 9. After the upper and lower lifting points are installed, the hydraulic lifter 9 can be activated to lift the lifting truss 15. Several equally spaced column stiffening plates 7 are fixedly connected at the connection between the lifting beam 5 and the first column 401. The column stiffening plates 7 strengthen the connection between the lifting beam 5 and the first column 401, improving the stability of the entire structure. The reinforcing steel plate 6 and the column stiffening plate 7 are usually made of high-strength steel and are fixedly connected to the lifting beam 5 and the column assembly 4 by welding.

[0029] refer to Figure 1 The diagonal brace 8 is inclinedly positioned between the lifting beam 5 and the column assembly 4, with its two ends connected to the third column 403 and the lifting beam 5 respectively via ear plates. The diagonal brace 8 enhances structural stability by transferring some of the force on the lifting beam 5 to the column assembly 4, reducing the stress on the middle of the lifting beam 5. The diagonal brace 8 is typically made of shaped steel, such as H-beams or channel steel. The ear plate design makes the connection of the diagonal brace 8 more flexible and robust, facilitating installation and adjustment of its angle.

[0030] refer to Figure 1 A steel embedded part 2 is installed on one side of each pair of supporting columns 1, and the steel embedded part 2 is fixedly installed inside the supporting column 1. The steel embedded part 2 is constructed together with the reinforcing steel in the supporting column 1, which ensures a tight connection between the steel embedded part 2 and the supporting column 1. A steel bracket 3 is fixedly connected to one side of the steel embedded part 2, and two steel brackets 3 are installed correspondingly. The steel brackets 3 are vertically fixedly connected to the column assembly 4. The steel brackets 3 are made of structural steel, such as H-beams or box-shaped steel components, which can transfer the load of the column assembly 4 to the supporting column 1. The steel brackets 3 are fixed to the steel embedded parts 2 by welding or bolts.

[0031] refer to Figure 2 and Figure 3The hydraulic lifter 9 is mounted on the reinforcing steel plate 6 and connected to the temporary ball lifting point 11 via steel strand 10. The steel strand 10 passes through a steel strand through-hole 560. The reciprocating operation of the hydraulic lifter 9 can drive the lifting truss 15 to rise. The temporary ball lifting point 11 connects to multiple temporary members 13. The temporary members 13 are connected to the support insert members 14 and the lifting truss 15 via ball joints. After the lifting truss 15 is lifted, the support insert members 14 connect to the truss support 12. After the lifting truss 15 is supported on the support column 1 via the truss support 12 and the support insert members 14, the lifting bracket, hydraulic lifter 9, and steel strand 10 are removed. This connection method makes the lifting process more stable and reliable. Several temporary members 13 are added to the temporary ball lifting point 11 and converge to form the lifting point. To facilitate the installation of the temporary members 13, the ball joints connected to the temporary members 13 need to be replaced with welded ball joints. The steel strand 10 passes through the temporary ball suspension point 11 and is fixedly connected to it using an anchor.

[0032] The implementation principle of this embodiment is as follows: the support column 1 and the lifting bracket are first fixedly connected. The lifting bracket consists of the support column 1, the column assembly 4, the lifting beam 5, the diagonal brace 8, the steel embedded part 2, the steel bracket 3, the reinforcing steel plate 6, and the column stiffening plate 7. The column assembly 1 is first set on the corresponding side of the support column 1, and the column assembly 4 is set as a multi-segment threaded connection. Multiple sections can be added to the second column 402 to adapt to the height adjustment required by the truss. A diagonal brace 8 is connected between the first column 401 and the lifting beam 5 to enhance the stability of the lifting truss 15 during lifting. This lifting bracket structure is simple in construction, adopting a prefabricated structure. The various components are assembled through welding, threaded connections, etc., making installation and disassembly convenient and greatly improving the efficiency of on-site construction. Compared with previous lifting frames, the optimized structure reduces the number of structural components and the amount of steel used in the steel structure, thereby reducing the material input and construction cost of temporary steel structures. Moreover, this lifting bracket can be reused, improving the turnover rate. Meanwhile, this design solves the technical problem of collision and interference between the 12 embedded rods at the gate truss support and the lifting bracket, avoiding the need to add rods after the structure is unloaded, and further improving the convenience and economy of construction.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
