Description

Technical Field

[0001] This utility model belongs to the field of auxiliary support technology for building construction, specifically a temporary support structure for inclined steel components. Background Technology

[0002] With the rapid development of the modern construction industry, large-span buildings such as stadiums, convention centers, and transportation hubs are becoming increasingly common. Due to their large spans and complex spatial structures, these buildings place extremely stringent requirements on construction support systems.

[0003] Traditional support structures often use fixed-size steel pipe scaffolding or custom-made steel supports, which have significant limitations: First, height adjustment relies on cutting or splicing steel pipes, making continuous and precise adjustment impossible and difficult to adapt to different construction height requirements. Furthermore, the stability of the structure is easily affected after adjustment. Second, the fixed angle cannot meet the needs of non-vertical support scenarios such as inclined beams and curved components in large-span buildings, requiring additional custom-made connectors, which increases construction costs and time. Third, the component connection ends have poor versatility, requiring the replacement of the entire support device for building components with different cross-sectional shapes, resulting in low adaptability. These problems lead to low construction efficiency and insufficient safety of traditional support structures, making it difficult to meet the efficient and flexible construction needs of large-span buildings.

[0004] Therefore, the development of a support structure that can flexibly adjust its height and angle and is compatible with a variety of components has become an urgent need in the industry. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a temporary support structure for inclined steel components, which enables continuous and precise height adjustment, and the positioning pin ensures the rigidity after adjustment; the angle adjustment component, with the help of a spherical hinge node and a locking device, can rotate at multiple angles, easily adapting to the support needs of inclined and curved components.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temporary support structure for inclined steel components, comprising a foundation fixing component, a height adjustment component, an angle adjustment component, and a component connection component; The basic fixing component consists of a reinforced concrete base and a pre-embedded connecting steel plate. The reinforced concrete base is equipped with a reinforcing steel mesh, and the pre-embedded connecting steel plate is reliably welded to the reinforcing steel mesh inside the reinforced concrete base to ensure the stability of the bottom of the supporting structure, effectively distribute the upper load, and form a reliable connection with the building foundation. The height adjustment component adopts a hydraulic lifting device and a combination structure of multiple telescopic steel pipes to achieve continuous adjustment of the support height; The angle adjustment component consists of a spherical hinge node and an angle locking device, which can realize multi-angle rotation of the support structure to adapt to the support angle requirements of inclined components in large-span buildings. The component connection assembly is a replaceable clamp-type connector that can be equipped with corresponding installation according to the cross-sectional shape of different components.

[0007] Preferably, the telescopic steel pipe includes a sleeve, a telescopic rod, a connecting frame, and multiple reinforcing crossbars. The sleeve is installed at the four corners of the pre-embedded connecting steel plate. The telescopic rod is slidably inserted into the sleeve. The telescopic rod is provided with a connecting frame away from the sleeve. Sleeves are installed at the four corners of the surface of the connecting frame away from the telescopic rod. The multiple reinforcing crossbars are connected to the four sleeves in pairs. Reinforcing crossbars are also installed between the telescopic rods.

[0008] Preferably, the hydraulic lifting device includes a hydraulic telescopic cylinder, a guide sleeve, and a support rod. The hydraulic telescopic cylinder is mounted on the surface of the reinforcing crossbar, the guide sleeve slides on the surface of the reinforcing crossbar, the guide sleeve is connected to the extended end of the hydraulic telescopic cylinder, the support rod is hinged to the surface of the guide sleeve, and the other end of the support rod is hinged to the guide sleeve on another set of hydraulic telescopic cylinders.

[0009] Preferably, a positioning pin is provided between the sleeve and the telescopic rod for segmented fixing to ensure the structural rigidity after height adjustment.

[0010] Preferably, the angle locking device is disposed on the surface of the topmost connecting frame. The angle locking device includes clamping blocks, guide rails, guide blocks, and locking bolts. The clamping blocks are symmetrically disposed on the surface of the connecting frame. The guide blocks are mounted on the bottom surface of the clamping blocks. The guide rails are formed on the surface of the connecting frame. Both the guide rails and guide blocks are U-shaped structures and are interlocked with each other. Both sets of locking bolts penetrate the clamping blocks. An arc-shaped groove adapted to the spherical hinge node is formed between the two clamping blocks for locking the spherical hinge node.

[0011] Preferably, the component connecting assembly is connected to the spherical hinge node via a connecting rod, and the clamp-type connector is detachably connected to the end of the connecting rod away from the spherical hinge node. The clamp-type connector includes a claw and a pad. The claw is equipped with a corresponding configuration according to the cross-sectional shape of different components, and the pad is disposed on the side of the contact surface between the claw and the component.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The height adjustment component uses a hydraulic lifting device in conjunction with a telescopic steel pipe to achieve continuous and precise height adjustment, while positioning pins ensure rigidity after adjustment. The angle adjustment component, with its spherical hinge joint and locking device, can rotate at multiple angles, easily adapting to the support needs of inclined and curved components without the need for additional custom-made parts. This significantly enhances its ability to handle complex scenarios and greatly improves construction efficiency. Hydraulic drive and mechanical locking complete the operation quickly. The component connection uses replaceable clamp-type connectors; simply changing the corresponding claw allows for adaptation to components with different cross-sections, saving time on rebuilding supports and effectively shortening the construction period. Meanwhile, the foundation fixing component uses a concrete base with reinforced steel mesh, combined with pre-embedded steel plates welded to the steel mesh, to distribute the load and ensure a stable connection. After height adjustment, it is fixed by positioning pins, and after angle adjustment, it is clamped by locking devices. This double fixing prevents displacement and deformation, reducing construction safety risks.

[0013] Overall cost reduction and adjustability decrease the cost of custom-made accessories. Components such as clamps and telescopic steel pipes can be reused, avoiding the waste of traditional support components and improving resource utilization. The overall cost advantage is obvious in long-term construction. With adjustable height, angle and replaceable clamps, it is not only suitable for large-span buildings such as stadiums and convention centers, but also can adjust parameters according to needs to adapt to construction scenarios of different scales and component types, breaking the limitation of "one project, one customization" and has high promotion value.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, this utility model provides a temporary support structure for inclined steel components, including a foundation fixing component 1, a height adjustment component 2, an angle adjustment component 3, and a component connection component 4; The foundation fixing component 1 consists of a reinforced concrete base 11 and a pre-embedded connecting steel plate 12. The reinforced concrete base 11 is internally equipped with a reinforcing steel mesh 13. The pre-embedded connecting steel plate 12 is reliably welded to the reinforcing steel mesh 13 inside the reinforced concrete base 11, ensuring the stability of the bottom of the supporting structure. This effectively distributes the upper load and forms a reliable connection with the building foundation. The pre-embedded connecting steel plate 12 and the reinforcing steel mesh 13 inside the reinforced concrete base 11 are reliably welded together, forming a robust whole. This connection method not only ensures the stability of the bottom of the supporting structure but also evenly distributes the upper load to the building foundation, achieving a reliable connection with the building foundation.

[0018] like Figures 1 to 4 As shown, the height adjustment component 2 adopts a combination structure of hydraulic lifting device 21 and multiple sets of telescopic steel pipes 22 to achieve continuous adjustment of the support height. The telescopic steel pipe 22 includes a sleeve 221, a telescopic rod 222, a connecting frame 223, and multiple reinforcing crossbars 224. The sleeve 221 is installed at the four corners of the pre-embedded connecting steel plate 12. The telescopic rod 222 is slidably inserted into the sleeve 221. The connecting frame 223 is set on the telescopic rod 222 away from the sleeve 221. Sleeves 221 are installed at the four corners of the side of the connecting frame 223 away from the telescopic rod 222. Multiple reinforcing crossbars 224 are connected to the four sleeves 221 in pairs. Reinforcing crossbars 224 are also installed between the telescopic rods 222. In practical applications, when it is necessary to adjust the height of the support structure, it can be initially adjusted by the hydraulic lifting device 21, and then fine-tuned by the telescopic steel pipe to achieve precise height control. In the construction of some large-span buildings, it may be necessary to continuously adjust the height of the supporting structure according to different construction stages and structural requirements. This goal can be easily achieved through the coordinated work of the height adjustment component 2, which greatly facilitates the construction.

[0019] It should be noted that a positioning pin 225 is provided between the sleeve 221 and the telescopic rod 222 for segmented fixing to ensure structural rigidity after height adjustment. The positioning pin 225 can be inserted into the corresponding pin holes on the sleeve 221 and the telescopic rod 222 after the telescopic rod 222 is adjusted to the appropriate height, fixing the telescopic rod 222 inside the sleeve 221 and preventing it from sliding or shifting during use. The positioning pin 225 acts like a sturdy lock, ensuring the stability of the telescopic steel pipe 22 after height adjustment and providing reliable protection for the supporting structure.

[0020] The height adjustment assembly 2 adopts a combination structure of a hydraulic lifting device 21 and multiple sets of telescopic steel pipes 22 to achieve continuous adjustment of the support height. The hydraulic lifting device 21 includes a hydraulic telescopic cylinder 211, a guide sleeve 212, and a support rod 213. The hydraulic telescopic cylinder 211 is mounted on the surface of the reinforcing crossbar 224, and the guide sleeve 212 slides on the surface of the reinforcing crossbar 224. The guide sleeve 212 is connected to the extended end of the hydraulic telescopic cylinder 211. The support rod 213 is hinged to the surface of the guide sleeve 212, and the other end of the support rod 213 is hinged to the guide sleeve 212 on another set of hydraulic telescopic cylinders 211. The lifting device 21 has multiple built-in hydraulic telescopic cylinders 211. The hydraulic telescopic cylinders 211 are driven by internal hydraulic oil to realize the extension and retraction of the piston rod, thereby driving the guide sleeve 212 to slide on the reinforcing crossbar 224. The support rod 213 is hinged to the guide sleeve 212, and its other end is hinged to the guide sleeve 212 on another set of hydraulic telescopic cylinders 211, thus forming a stable support structure. When the hydraulic telescopic cylinder 211 works, the guide sleeve 212 will move along the reinforcing crossbar 224, thereby changing the angle and position of the support rod 213 and realizing the adjustment of the support height.

[0021] like Figures 1 to 4As shown, the angle adjustment component 3 consists of a spherical hinge node 31 and an angle locking device 32, which can realize multi-angle rotation of the support structure to adapt to the support angle requirements of inclined components in large-span buildings. The angle locking device 32 is set on the surface of the topmost connecting frame 223. The angle locking device 32 includes a clamping block 321, a guide rail 322, a guide block 323, and a locking bolt 324. The clamping blocks 321 are symmetrically arranged on the surface of the connecting frame 223. The guide blocks 323 are installed on the bottom surface of the clamping blocks 321. The guide rail 322 is opened on the surface of the connecting frame 223. Both the guide rail 322 and the guide block 323 are convex structures and are interlocked with each other. Both sets of locking bolts 324 penetrate the clamping blocks 321. An opening is provided between the two clamping blocks 321 to connect with the spherical hinge node 321. The arc-shaped groove that matches the spherical hinge node 31 is used to lock the spherical hinge node 31. The angle adjustment component 3 is the core part of the support structure that can adapt to the support angle requirements of inclined components in large-span buildings. It consists of the spherical hinge node 31 and the angle locking device 32, giving the support structure the flexible rotation ability like a human joint. In practical applications, when encountering inclined components, the angle of the support structure is first adjusted through the spherical hinge node 31 to match the angle of the inclined component. Then, the angle is fixed using the angle locking device 32 to ensure that the support structure can stably support the inclined component. In the construction of some large stadiums, the inclined steel beams of the roof need precise support angles. The angle adjustment component 3 can play its advantage and provide reliable support for the inclined steel beams.

[0022] like Figures 1 to 4 As shown, the component connecting assembly 4 is connected to the spherical hinge node 31 via a connecting rod. A clamp-type connector 41 is detachably connected to the end of the connecting rod away from the spherical hinge node 31. The clamp-type connector 41 includes a claw 411 and a pad 412. The claw 411 is configured according to the cross-sectional shape of different components. The pad 412 is located on the side of the contact surface between the claw 411 and the component. The claw 411 is configured according to the cross-sectional shape of different components, such as round, square, or rectangular, and can tightly fit against the component surface, providing a reliable connection. The pad 412 is located on the side of the contact surface between the claw 411 and the component. Its function is to increase friction, prevent the claw 411 from sliding on the component surface, and also protect the component surface, preventing damage from the claw 411. In practical applications, when it is necessary to connect components with different cross-sectional shapes, simply select the appropriate clamp-type connector 41, install it on the connecting rod, and then use the claws 411 to firmly clamp the component, thereby achieving the connection between the support structure and the component. In the construction of large-span buildings, various types of components may be involved, such as steel beams, steel columns, and concrete beams. The component connection components can easily adapt to the connection requirements of these components, providing convenience for construction.

[0023] Working principle and process: The height adjustment component 2 uses a hydraulic lifting device 21 in conjunction with a telescopic steel pipe 22 to achieve continuous and precise height adjustment, and the positioning pin 225 ensures the rigidity after adjustment; the angle adjustment component 3, with the help of a spherical hinge node 31 and an angle locking device 32, can rotate at multiple angles, easily adapting to the support requirements of inclined and curved components, without the need for additional customized special parts, greatly enhancing its ability to cope with complex scenarios and significantly improving construction efficiency; the component connection component 4 uses a replaceable clamp-type connector 41, and by changing the corresponding claw 411, it can adapt to components with different cross-sections, saving the time of rebuilding the support and effectively shortening the construction period; at the same time, the reinforced concrete base 11 with a reinforcing steel mesh 13 on the foundation fixing component 1, combined with the pre-embedded connecting steel plate 12 welded to the steel mesh, distributes the load and stabilizes the connection; after height adjustment, it is fixed by the positioning pin 225, and after angle adjustment, it is clamped by the angle locking device 32, with double fixing to avoid displacement and deformation and reduce construction safety risks.
