Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, relates to a hyperboloid cable membrane canopy system and its installation method. Background Technology

[0002] With the acceleration of global urbanization, the demand for high-rise and super high-rise buildings is growing rapidly. Building construction machines, as key equipment in modern construction, play a crucial role in this wave. A building construction machine is an integrated construction platform that not only provides a stable supporting structure for buildings but also is equipped with advanced machinery and tools for core processes such as concrete pouring and rebar tying. Through modular design and an efficient vertical transportation system, building construction machines significantly improve the construction efficiency and safety of high-rise buildings, shorten construction cycles, and reduce labor costs. Furthermore, building construction machines can adapt to different types of building structures, whether residential, commercial, or public facilities, enabling rapid construction while ensuring quality.

[0003] The traditional canopy systems used in existing building construction machines mostly adopt flat or simple curved surface designs. Although these designs can meet basic sun shading and protection needs to a certain extent, they also expose a series of problems: First, the existing canopy of the building construction machine is mainly supported by a customized steel frame. This steel frame needs to be customized according to the size of the building before each construction. The canopy of different buildings cannot be used interchangeably, which is costly. Secondly, due to limitations in material selection and technology, the steel frame of the existing canopy system requires construction workers to disassemble each steel frame of the entire canopy system individually during installation and dismantling, resulting in extremely high labor costs. Furthermore, insufficient waterproofing performance may lead to rainwater seepage or rainwater accumulation on the canopy, which could adversely affect the construction environment below. Finally, traditional canopy systems have a large number of steel frames, and the steel frames as a whole do not have a certain degree of fine-tuning function. This makes it difficult to adjust the installation position and inconvenient to maintain during the installation process, which increases the complexity of on-site operation and further restricts the construction progress.

[0004] Therefore, developing a new type of canopy system that is more stable, durable and easy to adjust has become an urgent problem to be solved in the field of building technology. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a hyperboloid cable-stayed membrane canopy system and its installation method. The system employs a support assembly that can be spliced ​​and combined, with the membrane fabric assembly installed on the support assembly. A traction assembly then pulls up and retracts the flexible membrane fabric material, flexibly adapting to the construction needs of buildings of different sizes and shapes, thus improving the system's versatility and practicality.

[0006] To achieve the above objectives, according to one aspect of the present invention, a hyperboloid cable membrane canopy system is provided, comprising: The system includes a support assembly mounted on an external platform, a membrane fabric assembly mounted on the support assembly, a traction assembly connected to the membrane fabric assembly and capable of pulling the membrane fabric assembly, and a drainage assembly mounted on the support assembly and capable of draining accumulated water flowing down the membrane fabric assembly; wherein... The support assembly includes a mounting part installed on an external platform, a movable track installed on top of the mounting part, and a trolley that slides on the movable track; The membrane assembly includes a canopy membrane and a tensioning section connecting the canopy membrane to the trolley. The canopy membrane has two curved surface structures near its bottom that are inclined from the center of the canopy membrane toward the ends of the canopy membrane, forming a hyperboloid structure. The traction assembly includes a winch mounted on an external platform, a traction rope connecting the winch drum and the tensioning section, and a pulley structure in contact with the traction rope. The winch controls the unfolding and retraction of the membrane assembly on the movable track through the traction rope. The drainage component is located on the surface of the mounting section and guides the water flowing down from both ends of the canopy membrane near the trolley.

[0007] Furthermore, the mounting part includes a socket frame and a track fixing component disposed on the socket frame. The track fixing component includes a track clamping component, a fixing plate connecting the track clamping component and the socket frame, and an adjusting bolt disposed on the track clamping component. Furthermore, the surface of the track clip is provided with a slot that is adapted to the movable track, and the adjusting bolt extends from the outside of the track clip to the inside of the slot, with one end extending into the slot contacting the movable track.

[0008] Furthermore, the surface of the socket frame is provided with a stop block, and the side of the socket frame with the stop block faces the direction of the canopy membrane.

[0009] Furthermore, the tensioning section includes a collar disposed on the surface of the canopy membrane, a sleeve disposed within the collar, a tensioning rope passing through the inside of the sleeve, and a connector disposed at the end of the tensioning rope connecting the tensioning rope and the pulley. Each tensioning rope is provided with an auxiliary rope and a hand-operated hoist. The tensioning section enables several strip-shaped protrusions to be uniformly formed on the surface of the canopy membrane.

[0010] Furthermore, the pulley structure includes a pulley bracket mounted on an external platform, and a fixed pulley disposed on the pulley bracket, the fixed pulley being in contact with the surface of the traction rope.

[0011] Furthermore, adjacent active tracks are connected to each other via track docking components.

[0012] Furthermore, the surface of the trolley is provided with a limiting rope that connects adjacent trolleys together.

[0013] Furthermore, the drainage assembly includes a drainage channel and a bracket movably connected to the surface of the socket frame, wherein the drainage channel is connected to the socket frame via the bracket.

[0014] According to another aspect of the present invention, the present invention provides an installation method for a hyperboloid cable membrane canopy system, for implementing the installation of the hyperboloid cable membrane canopy system described above, comprising the following specific steps: S100: Adjust the walkway panel at the top of the platform, remove the railings at the edge of the platform to expose the slots on the Bailey panels, and use bolts to install the socket frame into the slots of the Bailey panels; install the track fastener on the top of the socket frame; embed the movable track into the slot of the track fastener, install the trolley on the movable track, and complete the installation of the support assembly; S200: Insert the sleeve into the pre-set loops on the surface of the canopy membrane, pass the tension rope through the inside of the sleeve, and install both ends of the tension rope on the two pulleys through the tensioning part. Slowly tension the tension rope and clamp the rope clamp on the auxiliary rope to fix it. Repeat the operation until all the loops and sleeves on the canopy membrane are installed on the pulleys through the tension rope to complete the installation of the membrane assembly. S300: Install the pulley structure and winch on the external platform; connect one end of the traction rope to the winch, and the other end, after passing over the fixed pulley, connect to the tension rope of the canopy membrane. S400: Install the drainage channel on the socket frame using the bracket, and adjust the inclination of the drainage channel so that the inclination direction of the drainage channel matches the direction of water sliding off the hyperboloid surface of the canopy, thus completing the installation of the entire canopy system.

[0015] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: 1. The present invention provides a hyperboloid cable membrane canopy system, which, by employing support components that can be spliced ​​and combined, and flexible membrane material that can be retracted and unfolded, can flexibly adapt to the construction needs of buildings of different sizes and shapes. Compared with traditional planar or simple curved surface designs, this modular design avoids the problem of customizing steel frames for each project in traditional canopy systems, thereby greatly reducing costs and improving the versatility and practicality of the system. 2. The hyperboloid cable membrane canopy system of the present invention adopts a modular design of the support components, which is a combination of socket frames and track fixing parts. The socket frames can be installed on the Bailey plate slots of different building steel platforms by means of bolts. The movable track can be finely adjusted in height to adapt to the installation requirements of different buildings by means of the slots of the track fixing parts and the adjusting bolts. This solves the problems of poor versatility and high cost caused by the customization of traditional canopy steel frames, greatly improves the versatility of the system, and reduces the customized production cost. 3. The hyperboloid cable membrane canopy system of the present invention can drive the trolley to slide along the movable track through a traction component consisting of a winch, a pull rope and a fixed pulley, thereby driving the canopy membrane to unfold or retract as a whole. There is no need to deal with the support structure separately during the disassembly and assembly process, which solves the problem that the traditional steel frame of the canopy needs to be disassembled and assembled separately and the labor cost is high. It greatly reduces the labor input, shortens the disassembly and assembly time, and reduces labor costs. 4. The present invention provides a hyperboloid cable membrane canopy system in which the canopy membrane adopts a hyperboloid structure that is inclined from the center to the ends, and is combined with drainage grooves at the edges to allow rainwater to naturally collect along the hyperboloid to the drainage grooves, and then be guided to the designated location by the drainage grooves. This avoids rainwater accumulation on the surface of the membrane or seepage into the construction area below, effectively improving the waterproof performance, ensuring the dryness and safety of the construction environment, and increasing the safety of construction. 5. The hyperboloid cable membrane canopy system of the present invention allows for fine adjustment of the track height via adjusting bolts on the track fixing components, fine adjustment of the tension rope tension via hand-operated hoists on the tensioning section, and adjustment of the drainage channel inclination via brackets on the drainage components. The multi-component adjustment function can quickly adapt to on-site errors, making the installation process more flexible and controllable, and also providing convenience for subsequent maintenance work. It reduces the extra workload caused by installation errors or problems during use, improves installation and maintenance efficiency, and ensures construction progress. Attached Figure Description

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the technical product is in use. They are only for the convenience of describing the technology 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 the technology.

[0023] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] Example 1 Please see Figure 1-10 This invention provides a hyperboloid cable-stayed membrane canopy system, including a support assembly 1 installed on a steel platform of a building construction machine, a membrane fabric assembly 2 disposed on the support assembly 1, a traction assembly 3 connected to the membrane fabric assembly 2, and a drainage assembly 4 installed on the support assembly 1. The support assembly 1 provides a stable and adaptable basic frame for the installation of the membrane fabric assembly 2 and the drainage assembly 4. The traction assembly 3 serves as a power source, pulling the membrane fabric assembly 2 to achieve the expansion and contraction of the canopy. The drainage assembly 4 can drain accumulated water flowing down the membrane fabric assembly 2.

[0025] Support assembly 1 includes a mounting part 12 mounted on an external platform, a movable track 11 mounted on top of the mounting part 12, and a trolley 13 capable of sliding along the movable track 11, wherein... The mounting part 12 includes a socket frame 121 and a track fastener 122 disposed on the socket frame 121. The track fastener 122 can connect the movable track 11 to the socket frame 121. Figure 9As shown, the track fixing component 122 consists of a track clip, a fixing plate connecting the track clip and the socket frame 121, and an adjusting bolt on the track clip. The track clip has a groove on its surface that is adapted to the movable track 11. The adjusting bolt extends from the outside of the track clip to the inside of the groove. One end of the adjusting bolt extending into the groove contacts the movable track 11. Preferably, there are two adjusting bolts in each track fixing component 122. During installation, the height of the movable track 11 inside the track fixing component 122 can be adjusted by controlling the tightness of the adjusting bolts, thereby adapting to the height difference between different movable tracks 11 during installation.

[0026] Meanwhile, a stop is provided on the surface of the socket frame 121. When the socket frame 121 is installed on the external platform, the side of the socket frame 121 with the stop faces the direction of the canopy membrane 21, which restricts the movement of the track 11 from sliding beyond the limit.

[0027] To ensure unobstructed flow after the multiple movable tracks 11 are connected, track docking parts are provided between adjacent movable tracks 11, which can connect adjacent movable tracks 11.

[0028] In this embodiment, the support component 1, the socket frame 121, and the track fixing component 122 not only provide strong mechanical fixing force but also have a certain adjustment function, allowing for fine-tuning of the canopy's position during installation to adapt to different site conditions. The enhanced connection reliability not only improves the safety of the entire system but also makes subsequent disassembly and maintenance more convenient.

[0029] The membrane assembly 2 includes a canopy membrane 21 and a tensioning section 22 mounted on a trolley 13. The tensioning section 22 can connect the canopy membrane 21 to the trolley 13. When the canopy membrane 21 is located on the surface of the tensioning section 22, it has two curved surface structures near the bottom that are inclined from the center of the canopy membrane 21 toward the end of the canopy membrane 21, forming a hyperboloid structure. The canopy membrane 21 is made of a membrane sheet made of weather-resistant and UV-resistant material through a specific connection process. The hyperboloid structure can be formed by a binding rope provided at the center of the canopy membrane 21, or it can be formed directly when splicing the canopy membrane 21.

[0030] The tensioning section 22 enables the uniform formation of several strip-shaped protrusions on the surface of the canopy membrane 21. The tensioning section 22 includes a collar on the surface of the canopy membrane 21, a sleeve inside the collar, a tension rope that can pass through the inside of the sleeve, and a connector at the end of the tension rope that can connect the tension rope to the pulley 13. Each tension rope is equipped with an auxiliary rope and a hand-operated hoist to allow for fine-tuning of the tension of the tension rope during installation, thereby adapting to errors in the installation environment at the construction site.

[0031] The traction assembly 3 includes a winch 31 mounted on the steel platform of the building construction machine, a pulley 32 connecting the drum of the winch 31 and the tensioning section 22, and a pulley structure 33 that contacts the pulley 32 and guides its direction. The canopy membrane 21 is suspended on the pulley 32, and the bottom of the canopy membrane 21 is inclined from its centerline toward its end. The winch 31 can drive the tensioning section 22 via the pulley 32 to control the unfolding and retraction of the membrane assembly 2 on the movable track 11. The pulley structure 33 includes a pulley bracket 331 mounted on an external platform and a fixed pulley 332 mounted on the pulley bracket 331. The fixed pulley 332 is in contact with the surface of the pull rope 32. The operator can effectively control the unfolding and retraction of the canopy membrane 21 by setting the arrangement of the fixed pulleys 332.

[0032] To prevent the canopy membrane 21 from shifting during deployment, the joints of the two pull ropes 32 must be aligned with the pulleys on the same side, and the surface of the trolley 13 must be equipped with limiting ropes to connect it to adjacent trolleys 13. The limiting ropes in the trolleys can restrict the relative displacement of adjacent trolleys, further ensuring the synchronization and morphological integrity of the canopy membrane during deployment and retraction.

[0033] The drainage component 4 is located on the surface of the mounting part 12 and can guide the water flowing down from both ends of the canopy membrane 21 near the trolley 13.

[0034] The drainage component 4 includes a drainage channel 41 and a bracket 42 connecting the drainage channel 41 and the socket frame 121. The bracket 42 is movably connected to the surface of the socket frame 121. By using the drainage channel 41 installed at the edge of the canopy membrane 21 in conjunction with the hyperboloid shape of the canopy membrane 21, it is ensured that rainwater and other water accumulation on the canopy can flow into the drainage channel 41 under severe weather conditions, and will not accumulate on the canopy membrane 21. This effectively improves the waterproof performance of the canopy system and also prevents the canopy from being damaged due to excessive water accumulation.

[0035] During the unfolding phase, after the winch 31 starts, its drum winds up the pulley rope 32. The pulley rope 32 changes the direction of force along the fixed pulley 332 of the pulley structure 33, thereby driving the tensioning part 22 connected to the pulley rope 32, causing the trolley 13 to slide along the movable track 11. Since the canopy membrane 21 is connected to the trolley 13 through the tensioning part 22, the sliding of the trolley 13 drives the canopy membrane 21 to unfold synchronously. Moreover, the bottom of the canopy membrane 21 is inclined from the center line to the end. With the help of the tensioning part's collar, sleeve, tension rope and auxiliary rope, and hand-operated hoist, the tension of the tension rope can be finely adjusted by the hand-operated hoist during the unfolding process to ensure that the surface of the canopy membrane 21 forms strip-shaped protrusions evenly, while ensuring the stability of the hyperboloid structure. During the retraction phase, the winch 31 reverses its rotation to release the pulley rope 32. The pulley rope 32 drives the tensioning part 22 and the trolley 13 to slide in the opposite direction along the movable track 11, and the canopy membrane 21 is folded and retracted accordingly.

[0036] The embodiments of the present invention achieve stable installation, flexible expansion and contraction, drainage of accumulated water, and dynamic adjustment to adapt to on-site working conditions through the precise cooperation of the support components, membrane fabric components, traction components, and drainage components. Specifically, the support components, as the mechanical load-bearing core of the system, are modularly combined and fixedly installed on external platforms such as the steel platform of the building construction machine, providing movable suspension support points for the membrane fabric components.

[0037] Example 2 In this embodiment, the hyperboloid cable membrane canopy system is also equipped with a control system. The operator can monitor and control the operating status of the canopy system through the control system, such as monitoring the tension of the cable membrane structure and controlling the start of the winch 31, so as to ensure the stability and safety of the canopy system.

[0038] Example 3 like Figure 11 As shown, this embodiment of the invention provides a method for the installation and calibration of a hyperboloid cable membrane canopy system, including the following specific steps: S100: Adjust the walkway plate on the top of the steel platform of the building construction machine, remove some of the railings on the edge of the platform to expose the slots on the Bailey panels, and use bolts to install the socket frame 121 into the slots of the Bailey panels; install the track fixing component 122 on the top of the socket frame 121; embed the movable track 11 into the slot of the track fixing component 122, splice adjacent movable tracks 11 through the track connecting component, install the trolley 13 on the movable track 11, and complete the installation of the support component; S200: Insert the sleeve into the pre-set collar on the surface of the canopy membrane 21, pass the tension rope through the inside of the sleeve, and install both ends of the tension rope on the two pulleys 13 through the tensioning part 22. Use the auxiliary rope on the tension rope and the hand chain hoist to slowly tension the tension rope. After the tension meets the requirements, clamp the rope on the auxiliary rope to fix it and prevent the tension rope from loosening. Repeat the operation until all the collars and sleeves on the canopy membrane 21 are installed on the pulleys 13 through the tension rope to complete the installation of the membrane assembly. S300: Install the pulley bracket 331 at the preset position on the steel platform of the building construction machine, and then install the fixed pulley 332 on the pulley bracket 331 to ensure that the rotation axis of the fixed pulley is compatible with the force direction of the tension rope; install the winch 31 on the steel platform of the building construction machine; connect one end of the tension rope 32 to the drum of the winch 21, and after passing the fixed pulley 332, connect the other end to the first tension rope of the canopy membrane 21.

[0039] S400: The drainage channel 41 is installed on the socket frame 121 by the bracket 42, and the tilt of the drainage channel 41 is adjusted by adjusting the height of the bracket 42 on the socket frame 121 so that the tilt direction of the drainage channel 41 matches the direction of water accumulation and sliding of the hyperboloid surface of the canopy, ensuring that subsequent rainwater can flow smoothly into the drainage channel, and finally completing the installation of the entire canopy system.

[0040] The above embodiments, through precise measurement and positioning of the building-building machine's support structure, allow for adjustment of the 32% prestress in the tension ropes, ensuring uniform cable net tension that meets design requirements. This effectively enhances the overall rigidity of the canopy system and significantly improves structural stability. Furthermore, the use of modular support components and retractable flexible canopy membrane material allows for flexible adaptation to the construction needs of buildings of different sizes and shapes. This modular design avoids the need for customized steel frames for each project, as required by traditional canopy systems, thereby greatly reducing costs and improving the system's versatility and practicality. Based on the aforementioned technologies, the installation and dismantling process has been simplified. Only the basic installation of support component 1 needs to be completed, and then the canopy is tensioned and connected to the support structure. This not only reduces the need for a large amount of manpower but also shortens the construction preparation time, greatly saving labor and monetary costs. Furthermore, the improved canopy membrane uses advanced waterproof materials and technologies to effectively prevent rainwater penetration or accumulation on the membrane surface, ensuring a safe and dry construction environment below and increasing construction safety. In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
