Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, and particularly relates to a support structure for a special-shaped structural member. BACKGROUND

[0002] With the development and update of cities, steel structure buildings have gradually become an important structure form and are indispensable in modern building structures. As a type of building structure, steel structures are different from reinforced concrete structures. Steel structure buildings are made of steel as the main material, have the characteristics of overall lightness, foundation saving, less material, low cost, short construction period, large span, safety and reliability, aesthetic appearance, stable structure and the like.

[0003] Due to the increasing diversification of current building appearance and function requirements, the requirements for steel structures are also increasingly high. The ordinary spatial steel structure form cannot meet the use requirements, and therefore more structure forms are needed to meet the requirements. The installation of special-shaped spatial steel structure members has always been a construction difficulty. The installation form usually adopts factory installation or on-site installation, and the two installation methods have advantages and disadvantages.

[0004] Although factory assembly has good effect, high speed and high quality, it has high transportation requirements and high component transportation cost. This method is suitable for projects with small scale or good transportation conditions, but for large or complex special-shaped structural members, many challenges may be faced in the transportation process, such as road restrictions, transportation equipment restrictions and the like. These factors will greatly increase the cost and risk of the project.

[0005] On-site assembly has smaller transportation requirements, but the assembly conditions are limited, the construction quality is not high, and the efficiency is low. In the construction site, due to the limitation of space, equipment and human resources, the accurate positioning and installation of special-shaped structural members become very difficult. In addition, the uncertainty of the on-site environment, such as weather changes, terrain conditions and the like, will also have a negative impact on the construction quality and efficiency. Although this method solves the transportation problem to some extent, it brings new construction difficulties.

[0006] These problems are a great constraint factor for the development of steel structure buildings. The assembly difficulty of special-shaped structural members directly affects the overall quality and construction period of the building, and also increases the construction cost, which is a great constraint factor for the development of steel structure buildings.

[0007] Therefore, in order to solve the above problems, a support structure for special-shaped structural members is needed, which can assemble the special-shaped spatial steel structure members with higher construction quality and efficiency in the construction site with limited assembly conditions.

[0033] Figure 1 ​​As shown in the figure, the support structure for assembling the irregular structural component 002 in this embodiment includes a support body 001 and structural components 002 assembled on the support body 001. The assembly methods of the support body 001 and the structural components 002 include welding, bolting, or riveting. In this solution, the support body 001 is arranged along the height direction, and the structural components 002 include several arranged circumferentially on the support body 001. The assembly method of the support body 001 and the structural components 002 is welding. Before welding, the corresponding structural components 002 are positioned to the preset position of the support body 001 using this support structure.

[0034] The support structure includes a support assembly, which comprises a support base 1 and a fork arm 3 mounted on the support base 1 via a revolute joint I2. The revolute joint I2 can be a hinge, universal joint, or ball joint, etc. The fork arm 3 has grippers that support the structural component 002. The grippers can be mechanical grippers, electromagnetic chucks, or support-type limiting grooves, etc. The mechanical grippers can be further designed as V-shaped grippers, C-shaped grippers, or parallel grippers to accommodate structural components 002 with different cross-sectional shapes, which will not be elaborated here. The support base 1 is driven to adjust to a preset height so that the preset structural component 002 is supported in a set position by the grippers of the fork arm 3. The height adjustment of the support base 1 can be achieved by a hydraulic cylinder, a lead screw and nut mechanism, or a gear and rack mechanism. This solution, with its adjustable height support assembly and multi-degree-of-freedom fork arm 3 structure, can adapt to the complex assembly position requirements of irregularly shaped structural components 002 in space. This equipment can accurately position and support irregularly shaped structural components 002, and its simple structure facilitates operation. It solves the problems of limited on-site assembly conditions and low construction quality, offering advantages such as improved assembly efficiency, enhanced assembly quality, reduced construction costs, and increased construction safety. Specifically, the height-adjustable support base 1 addresses the assembly requirements of structural components 002 at different elevations, while the fork arm 3 with a rotating joint I2 allows the grippers to flexibly adjust their posture within the workspace. During use, the structural component 002 simply needs to be placed on the gripper. Compared to traditional fixed support fixtures, this equipment significantly improves the positioning accuracy and assembly efficiency of irregularly shaped structural components 002 in confined construction environments, effectively solving quality problems caused by limited on-site assembly conditions. In practical implementation, the drive system of the support base 1 can employ closed-loop control to ensure positioning accuracy, and the rotating joint I2 of the fork arm 3 can be configured with a damper to maintain posture stability; these settings are determined according to actual conditions and will not be elaborated further here.

[0035] In this embodiment, the clamping jaws of the fork arm 3 are C-shaped, and the middle part of the C-shaped structure is connected to the rotating pair I2 through a support rod. During use, the structural member 002 is limited and supported through the opening of the C-shaped structure. The rotating pair I2 includes a universal coupling that connects the fork arm 3 and the support seat 1. The universal coupling can be any existing technology. One end of the universal coupling is fixed to the fork arm 3, and the other end is fixed to the support rod connecting the clamping jaws. By using the universal coupling as the core component of the rotating pair I2, the technical problem of multi-angle adjustment during the assembly of the special-shaped structural member 002 is effectively solved. Specifically, the universal coupling allows the fork arm 3 to rotate freely in multiple directions, thereby adapting to the assembly requirements of special-shaped structural members 002 at different angles and positions. Compared with traditional single rotating pairs, the universal coupling provides greater adjustment freedom, allowing the clamping jaws to more accurately support the structural member 002 at the designated position. This design significantly improves the adaptability and operational flexibility of the assembly equipment, and is particularly suitable for the assembly of special-shaped structural members 002 with complex spatial angles.

[0036] In this embodiment, the structural member 002 includes several structural members arranged circumferentially around the support body 001, and the support assembly includes several groups of support assemblies corresponding to the structural members 002. The support structure further includes a connecting member that connects the corresponding support seats 1 in adjacent support assemblies. By arranging multiple groups of support assemblies corresponding to the structural members 002 and using the connecting member to connect adjacent support seats 1, synchronous positioning and support of multiple structural members 002 can be achieved. Compared with existing technologies, this scheme improves assembly efficiency and ensures the relative positional accuracy between multiple structural members 002, and is particularly suitable for situations where multiple circumferentially arranged structural members 002 need to be assembled simultaneously. The connecting member can be a rod structure, a telescopic rod 4 structure, or other structures with connecting functions, and will not be described here.

[0037] In this embodiment, the connecting member includes a telescopic rod 4 with adjustable length and a fastener 5 arranged on the telescopic rod 4 through a rotating pair II. The adjustable length design of the connecting member can adapt to the arrangement requirements of support seats 1 with different spacings. The length adjustment of the telescopic rod 4 can be achieved through a threaded pair, a hydraulic cylinder, or an electric push rod, etc. to adapt to installation positions with different spacings. The telescopic rod 4 is detachably connected to the support seat 1 through the fastener 5. The fastener 5 can be a clamp, a limiting sleeve, or a clamping jaw, etc. to meet the detachable limiting function. The detachable function of the telescopic rod 4 on the support seat 1 makes this scheme have the advantage of strong universality. As a preferred embodiment, the connecting surface of the fastener 5 and the structural member 002 can be provided with anti-slip patterns or rubber pads to enhance friction and improve the positioning and supporting effect on the structural member 002. This will not be described here.

[0038] In this embodiment, the existing technology is used to adopt the damping pull-out telescopic rod 4, and the fast release clamp structure in the prior art is used to ensure the stability of the connection, realize the quick connection and separation of the connecting rod and the structural member 002; the rotating pair II adopts a hinge structure, so that the fastener 5 can rotate around the axis connected with the telescopic rod 4. More specifically, the rotating pair II includes an intermediate shaft 6 that connects the telescopic rod 4 and the fastener 5, that is, the telescopic rod 4, the intermediate shaft 6 and the clamp constitute the rotating pair II, and the axes of the intermediate shafts 6 corresponding to the two fasteners 5 arranged on the same telescopic rod 4 are parallel, so as to ensure the stability of the connecting piece during adjustment, and the connecting piece can also function as a limiting function for the support seat 1, thereby ensuring that the structural member 002 is stably supported at the set position. Through the combination of the telescopic rod 4 with adjustable length and the rotatable fastener 5, flexible adjustment of the distance between adjacent support assemblies and angle adaptation are realized. In the specific working process, the length adjustment function of the telescopic rod 4 can adapt to the installation requirements of structural members 002 with different distances, the structure of the rotating pair II allows the fastener 5 to automatically adjust the angle according to the position of the structural member 002, and the fasteners 5 arranged at both ends of the telescopic rod 4 ensure uniform distribution of the connecting force. Compared with the fixed length connecting rod, this design significantly improves the adaptation ability of the equipment to different specifications of the special-shaped structural member 002, and solves the problem of connection difficulty caused by the size deviation of the components during on-site assembly. At the same time, the detachable connection mode facilitates quick disassembly and maintenance, and reduces the construction complexity.

[0039] In this embodiment, the support structure further includes a lifting assembly, which includes a base arranged at a preset position and a sliding seat driven to lift on the base, and the support seat 1 is arranged on the sliding seat. The lifting assembly can be a hydraulic cylinder structure, a pneumatic cylinder structure, a jack structure or a lifting platform structure, and is preferably suitable for meeting the preset lifting requirements, which will not be described here. The lifting assembly includes a plurality of groups arranged in a one-to-one corresponding relationship with the support seat 1. By arranging multiple groups of independently controlled lifting assemblies, the height position of each support seat 1 can be accurately adjusted to adapt to the complex assembly requirements of the special-shaped structural member 002 in space. Compared with the fixed height support mode, this design solves the assembly difficulty problem caused by the space position difference of the special-shaped structural member 002, realizes quick positioning through the height adjustable mechanism, and improves the assembly accuracy and efficiency. The modular design of the lifting assembly facilitates the increase or decrease of the number according to actual needs, and enhances the adaptability of the equipment.

[0040] In this embodiment, the support structure also includes a hydraulic pump station 003, which can be any existing technology. The lifting assembly includes a hydraulic cylinder 7 connected to the hydraulic pump station 003. More specifically, the hydraulic cylinder 7 is connected to the hydraulic pump station 003 through an oil pipe. The hydraulic pump station 003 serves as a power source to provide hydraulic oil for the hydraulic cylinder 7. By controlling the flow direction and flow rate of the hydraulic oil, the piston can be lifted or lowered. The hydraulic drive method has the characteristics of high load capacity and high positioning accuracy. A balance valve is provided on the hydraulic cylinder 7 to ensure that the support weight will not slide down in the event of an external oil pipe burst or other accidents, providing higher safety and effectively solving the stability problem of the hydraulic cylinder 7 during the assembly process of the special-shaped structural member 002 due to load changes or system pressure fluctuations. The balance valve can be any existing technology. Compared with the prior art, this scheme significantly improves the safety and reliability of the assembly process, and is especially suitable for working conditions with complex construction site conditions and frequent load changes. The setting of the balance valve also reduces the need for manual intervention of the hydraulic system by the operator, improving assembly efficiency. It should be understood that the hydraulic pump station 003 has a control screen and is electrically connected to each group of hydraulic cylinders 7. Each group of hydraulic cylinders 7 can be independently controlled to achieve synchronous lifting or individual adjustment through a PLC system to meet the assembly requirements of different height positions. The hydraulic pump station 003 can be equipped with a pressure regulating valve and a flow control valve to adapt to different load and speed requirements. The hydraulic system can be provided with a pressure sensor and a position sensor to realize closed-loop control. The actual situation is selected and will not be described here.

[0041] In this embodiment, the cylinder body of the hydraulic cylinder 7 is provided as a base at a predetermined position, and the piston of the hydraulic cylinder 7 is connected to the support base 1 as a sliding base. The piston and the support base 1 are assembled by flange connection, which realizes quick disassembly and maintenance of the hydraulic cylinder 7 and the support base 1. Compared with the traditional welding or threaded direct connection method, the flange connection has higher connection stiffness and positioning accuracy, can effectively transfer the push-pull force of the hydraulic cylinder 7 and withstand the eccentric load torque during the assembly process. The modular design of the flange connection facilitates on-site adjustment of the angle of the support base 1, while reducing the disassembly difficulty during maintenance of the hydraulic cylinder 7. In specific implementation, the flange connection structure can select different specifications of flange plates and bolt sets according to actual load requirements, which has good engineering adaptability and will not be described here. This technical scheme realizes the lifting adjustment of the support assembly by hydraulic drive, which has greater output force and better impact resistance compared with mechanical or electric drive methods. The hydraulic system can stably bear the weight of the special-shaped structural member 002 and maintain stable support force during the assembly process. Since the cylinder body of the hydraulic cylinder 7 directly serves as the base, the structure is simplified, the intermediate transmission link is reduced, and the rigidity and response speed of the system are improved. The centralized oil supply of the hydraulic pump station 003 facilitates synchronous control of multiple lifting assemblies to ensure coordinated action of each support point. This design is particularly suitable for precise assembly of heavy special-shaped structural members 002 in space-limited construction sites.

[0042] In the embodiment, the connecting piece is assembled at the end of the cylinder body close to the piston, that is, the connecting piece is located at the upper area of the cylinder body of the hydraulic cylinder 7, which not only ensures the linkage stability between the support assemblies, but also avoids movement interference; secondly, the arrangement makes the connecting piece in a relatively fixed position, which is convenient for on-site quick disassembly and assembly; finally, by setting the connecting point at the upper part of the cylinder body, the lateral load transmitted by the support assembly can be effectively shared, and the stability of the overall structure is improved. Compared with the scheme of setting the connecting piece on the piston rod, the design is more conducive to maintaining the positioning accuracy of the connecting piece, while reducing the vibration influence in the movement process of the hydraulic cylinder 7.

[0043] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
