Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, and in particular to a sunshade device. Background Technology
[0002] In the construction of suspension bridges, the main cable saddle is typically constrained at the tower top using sliding constraint. Its structure mainly consists of a grid reaction frame, a lower bearing plate, an upper bearing plate, and the main cable saddle body. The lower bearing plate is securely fixed to the grid reaction frame, while the main cable saddle body is fixed to the upper bearing plate. There are two types of friction between the upper and lower bearing plates: sliding friction and rolling friction. If rolling friction is used, a roller system must be added between the upper and lower bearing plates. Regardless of the type of friction, extremely high flatness is required on the surfaces of the upper and lower bearing plates.
[0003] During the main cable saddle construction phase, intense sunlight during the day causes the steel structure to rapidly heat up. During this period, the grid reaction frame, lower bearing plate, and upper bearing plate are directly exposed to sunlight. Due to thermal expansion and contraction, the flatness of the surfaces of the upper and lower bearing plates is affected, thus altering the coefficient of friction. Only after the main cable saddle body is installed, and with its shading effect, can the grid reaction frame, lower bearing plate, and upper bearing plate be protected from direct sunlight, preventing temperature deformation.
[0004] Therefore, during the construction of the main cable saddle, in order to ensure that the surface flatness of the upper and lower bearing plates is not affected by sunlight and to maintain a stable coefficient of friction, it is necessary to design special sunshade equipment at the top of the tower to effectively solve the above problems. Utility Model Content

[0033] The shading device proposed in this utility model provides a stable installation foundation for the shading device by setting up a support component on the top of the construction tower to form a working space, ensuring that the entire shading device can be reliably installed on the tower top. The top canopy is movably connected to the top of the support component and can be opened or closed to cover the top of the working space. During the day when the sunlight is strong, the top canopy can cover the top of the working space, effectively blocking direct sunlight from hitting the grid reaction frame, lower support plate, and upper support plate, avoiding the impact of thermal expansion and contraction of the structure due to sunlight on the surface flatness and friction coefficient of the upper and lower support plates. When shading is not needed, the top canopy can be opened to facilitate construction operations. The side enclosure is movably connected to the perimeter of the support component and can be opened or closed to cover the sides of the working space. On the one hand, it can further block sunlight from hitting the relevant structures from the side, enhancing the shading effect; on the other hand, it can be opened when not needed without affecting the operation of construction personnel on the side.
[0034] This shading device allows operators to flexibly open and close the top canopy and side barriers according to the construction progress and the angle of sunlight. It can quickly form all-round shading during construction breaks or periods of strong sunlight, effectively blocking direct sunlight from contacting key components such as the grid reaction frame, lower support plate, and upper support plate, reducing their temperature rise and suppressing surface deformation caused by thermal expansion and contraction. It can also conveniently open part or all of the top canopy and side barriers when hoisting or operation is required, ensuring unimpeded construction. This dynamically adjustable shading method improves the adaptability and flexibility of the shading equipment. Attached Figure Description

[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0045] In the construction of suspension bridges, the main cable saddle is typically constrained at the tower top using sliding constraint. Its structure mainly consists of a grid reaction frame, a lower bearing plate, an upper bearing plate, and the main cable saddle body. The lower bearing plate is securely fixed to the grid reaction frame, while the main cable saddle body is fixed to the upper bearing plate. There are two types of friction between the upper and lower bearing plates: sliding friction and rolling friction. If rolling friction is used, a roller system must be added between the upper and lower bearing plates.
[0046] Regardless of the type of friction, extremely high requirements are placed on the flatness of the upper and lower bearing plates. During the main cable saddle construction phase, daytime sunlight is intense, and steel structures are characterized by rapid heat absorption and temperature rise. During this period, the grid reaction frame, lower bearing plate, and upper bearing plate are directly exposed to sunlight. Due to thermal expansion and contraction, the flatness of the upper and lower bearing plates is affected, thus altering the coefficient of friction. Only after the main cable saddle body is installed, and with the saddle body's ability to block sunlight, can the grid reaction frame, lower bearing plate, and upper bearing plate be protected from direct sunlight, preventing temperature deformation.
[0047] Therefore, during the construction of the main cable saddle, in order to ensure that the surface flatness of the upper and lower bearing plates is not affected by sunlight and to maintain a stable coefficient of friction, it is urgent to design special sunshade equipment at the top of the tower to effectively solve the above problems.
[0048] See Figures 1 to 4 The shading device provided in this embodiment of the utility model includes a support component 1, a top canopy 2, and a side enclosure 3. The support component 1 is disposed on the top 100 of the construction tower, forming a working space. The top canopy 2 is movably connected to the top of the support component 1, and can be opened or covered to cover the top of the working space. The side enclosure 3 is movably connected to the periphery of the support component 1, and can be opened or covered to cover the sides of the working space.
[0049] The shading device proposed in this utility model provides a stable installation foundation for the shading device by setting a support component 1 at the top 100 of the construction tower to form a working space, ensuring that the entire shading device can be reliably installed at the top of the tower. The top canopy 2 is movably connected to the top of the support component 1, and can be opened or closed to cover the top of the working space. When the sunlight is strong during the day, the top canopy 2 can cover the top of the working space, effectively blocking direct sunlight from hitting the grid reaction frame, lower support plate, and upper support plate, avoiding the impact of thermal expansion and contraction of the structure due to sunlight on the surface flatness and friction coefficient of the upper and lower support plates. When shading is not needed, the top canopy 2 can be opened to facilitate construction operations. The side enclosure 3 is movably connected to the perimeter of the support component 1, and can be opened or closed to cover the sides of the working space. On the one hand, it can further block sunlight from hitting the relevant structures from the side, enhancing the shading effect; on the other hand, it can be opened when not needed, without affecting the operation of construction personnel on the side.
[0050] This shading device allows operators to flexibly open and close the top canopy 2 and side enclosure 3 according to the construction progress and the angle of sunlight. It can quickly form all-round shading during construction breaks or periods of strong sunlight, effectively blocking direct sunlight from contacting key components such as the grid reaction frame, lower support plate, and upper support plate, reducing their temperature rise and suppressing surface deformation caused by thermal expansion and contraction. It can also conveniently open part or all of the top canopy 2 and side enclosure 3 when hoisting or operation is required, ensuring unimpeded construction. This dynamically adjustable shading method improves the adaptability and flexibility of the shading device.
[0051] The specific structure and working principle of this sunshade device will be explained in detail below.
[0052] Support component 1 is installed at the top of the construction tower 100. Support component 1 encloses and forms a working space. Support component 1 is used to support the top canopy 2 and the side enclosure 3.
[0053] Specifically, the support component 1 encloses a rectangular working space, with a side enclosure 3 installed on each side of the working space. Each side enclosure 3 can be opened or closed individually, covering the corresponding side of the working space. The rectangular shape of the working space facilitates the rational planning of the construction area, conforms to the layout requirements of the construction site, and provides a regular space for construction operations. The side enclosure 3 of each working space can be operated independently, improving the flexibility of the shading equipment. During construction, if a certain side requires more light or construction personnel need to frequently enter and exit from a certain side, the corresponding side enclosure 3 can be opened individually, while the enclosures on other sides remain closed. This does not affect the construction on that side, but also continues to provide shading for the grid reaction frame, lower support plate, upper support plate, and other structures on other sides, effectively maintaining the surface flatness and friction coefficient of the upper and lower support plates, ensuring that the main cable saddle construction is not affected by sunlight, and guaranteeing the smooth progress of construction.
[0054] Furthermore, the support component 1 includes two upper longitudinal beams 11 arranged parallel to the top edge of the work space and two lower longitudinal beams 12 arranged parallel to the bottom edge of the work space. Multiple crossbeams 13 are connected between the two ends of the two upper longitudinal beams 11 to form a top rectangular frame and are connected between the two ends of the two lower longitudinal beams 12 to form a bottom rectangular frame. Multiple columns 14 are connected between the upper longitudinal beams 11 and the lower longitudinal beams 12. The top rectangular frame, the bottom rectangular frame, the crossbeams 13 and the columns 14 together enclose the work space.
[0055] The parallel upper longitudinal beam 11 and lower longitudinal beam 12, located at the top and bottom edges of the work space respectively, provide stable upper and lower boundaries for the entire support assembly 1, giving it good load-bearing capacity and stability in the vertical direction. Multiple crossbeams 13 connect the two ends of the upper longitudinal beam 11 to form a top rectangular frame and connect the two ends of the lower longitudinal beam 12 to form a bottom rectangular frame. This not only enhances the overall integrity of the top and bottom structures of the work space, but the rectangular frame structure also helps to evenly distribute the pressure from the top canopy 2 and the side enclosure 3. Multiple columns 14 connect the upper longitudinal beam 11 and the lower longitudinal beam 12, further strengthening the vertical support force of the support assembly 1, enabling the entire support assembly 1 to stably withstand various external forces. The top rectangular frame, bottom rectangular frame, crossbeams 13, and columns 14 together enclose the work space, ensuring its regularity and stability, providing a reliable connection foundation for the top canopy 2 and the side enclosure 3, thereby ensuring that the shading equipment can be stably installed on the top of the construction tower 100.
[0056] Preferably, a reinforcing diagonal brace 15 is provided between the upper longitudinal beam 11 and the lower longitudinal beam 12. The reinforcing diagonal brace 15 can effectively distribute loads from the top canopy 2, the side enclosure 3, and possible external wind forces, transferring these forces more evenly to the entire support structure. In this way, the pressure borne by the upper longitudinal beam 11 and the lower longitudinal beam 12 individually is reduced, decreasing the risk of deformation due to excessive local stress. In the face of severe weather conditions such as strong winds, the reinforcing diagonal brace 15 can enhance the ability of the support component 1 to resist lateral forces, preventing the support component 1 from tilting or collapsing due to lateral forces. This ensures that the sunshade equipment is stably installed at the top of the construction tower 100, continuously providing reliable sunshade protection for the construction of the main cable saddle of the suspension bridge, ensuring smooth construction, and improving the safety and reliability of the construction process.
[0057] In this embodiment, the bottom of the column 14 is anchored to the top of the construction tower 100 via pre-embedded bolts 16. This anchoring method with pre-embedded bolts 16 ensures a tight connection between the column 14 and the top of the construction tower 100, effectively resisting external forces from all directions, such as wind, the weight of the shading equipment itself and its supporting components, preventing displacement or tipping of the shading equipment during use. This anchoring method is relatively secure and easy to operate. Pre-embedding bolts at the top of the construction tower 100 allows for direct connection and fixation during the subsequent installation of the column 14, improving installation efficiency and reducing construction time. Furthermore, the pre-embedded bolts 16 ensure that the force at the bottom of the column 14 is evenly transmitted to the top of the construction tower 100, further enhancing the stability of the connection between the shading equipment and the tower top, ensuring stable operation of the shading equipment throughout the main cable saddle construction.
[0058] The top canopy 2 is movably connected to the top of the support assembly 1, and the top canopy 2 can be opened or covered to cover the top of the work space.
[0059] Specifically, the top canopy 2 is slidably or rollably connected to the support component 1. The top canopy 2 can move horizontally, thereby opening or covering the top of the work space. This connection method is convenient to operate, allowing construction personnel to quickly adjust the position of the top canopy 2 according to actual construction needs, switching between the open and covered states of the work space's top, thus improving construction efficiency. Compared to other connection methods, the sliding or rolling connection imposes fewer restrictions on the movement of the top canopy 2, enabling smoother horizontal movement, reducing the risk of equipment damage due to movement jams, and extending the service life of the shading equipment. In addition, the horizontally moving top canopy 2 does not occupy additional vertical space when open, better adapting to the limited space environment at the top of the construction tower 100, facilitating various operations by construction personnel within the work space, while simultaneously and accurately and effectively blocking direct sunlight when covered, ensuring that the main cable saddle construction is not affected by sunlight.
[0060] More specifically, two I-beams 4 are arranged horizontally and parallel to each other at the top of the support assembly 1; pulley assemblies 21 are arranged on both sides of the top canopy 2, each pulley assembly 21 including a plurality of pulleys 211; wherein, at least one pulley 211 is configured to roll on the upper surface of the upper flange 41 of the I-beam 4 to provide vertical support; at least two pulleys 211 are configured to roll in the intersection area of the lower surface of the upper flange 41 of the I-beam 4 and the web 42 on both sides to provide lateral restraint; the pulleys 211 are capable of rolling along the extension direction of the I-beam 4, thereby driving the top canopy 2 to move horizontally on the top of the support assembly 1.
[0061] The parallel I-beams 4 at the top of the support assembly 1 provide a reliable track foundation for the movement of the roof 2. In the pulley assemblies 21 on both sides of the roof 2, some pulleys 211 roll on the upper surface of the upper flange 41 of the I-beam 4, providing vertical support and effectively bearing the weight of the roof 2, ensuring it will not sag due to gravity during movement. Other pulleys 211 roll in the intersection area between the lower surface of the upper flange 41 and the web 42 on both sides of the I-beam 4, providing lateral restraint and preventing lateral displacement of the roof 2 during movement, ensuring the stability and accuracy of the roof's horizontal movement. Through the coordinated work of multiple pulleys 211, the roof 2 can roll smoothly and steadily along the extension direction of the I-beam 4, enabling flexible horizontal movement of the roof 2 on top of the support assembly 1. This allows for rapid opening and covering of the workspace roof, meeting the shading needs of different construction stages, while also improving the overall reliability and durability of the shading equipment.
[0062] In other embodiments, multiple spherical casters may be evenly distributed at the bottom of the top cover 2, and a flat or slightly curved support surface adapted to the spherical casters may be provided on the top of the support assembly 1. The spherical casters can roll freely on the support surface and can turn in multiple directions. By controlling the rolling direction of the spherical casters, the top cover 2 can be moved horizontally on the top of the support assembly 1 to complete the opening and closing operation of the top of the work space.
[0063] Alternatively, a dovetail groove can be provided horizontally on the top of the support component 1. The trapezoidal cross-section of the dovetail groove effectively prevents the slider from detaching. Sliders adapted to the dovetail groove are installed on both sides of the top cover 2. The sliders are embedded in the dovetail groove, and guided by the dovetail groove, the sliders can slide smoothly within the dovetail groove, driving the top cover 2 to move horizontally, thereby opening and closing the top of the work space.
[0064] It is understandable that the connection method between the top canopy 2 and the support component 1 is not limited here, as long as it can be ensured that the top canopy 2 can move horizontally relative to the support component 1.
[0065] Furthermore, the center of the top canopy 2 bulges upwards and slopes downwards from the center outwards. In rainy weather, rainwater can quickly flow away along the sloping surface of the top canopy 2, preventing water accumulation. Water accumulation can increase the load on the top canopy 2, and prolonged water accumulation can damage the material. This sloping design effectively reduces such risks and extends the service life of the top canopy 2.
[0066] The side enclosure 3 is movably connected to the periphery of the support component 1, and the side enclosure 3 can open or cover the side of the work space.
[0067] Specifically, the side enclosure 3 includes a roller 31 and a roller blind. The roller 31 is rotatably mounted on the side of the support assembly 1. One end of the roller blind is fixedly connected to the roller 31, and the other end is free. The roller blind can be rolled up on the roller 31 or unrolled from the roller 31. When the roller blind is rolled up on the roller 31, the corresponding side of the work space is in an open state; when the roller blind is unrolled from the roller 31, the corresponding side of the work space is in a covered state. The use of a roller 31 rotatably mounted on the side of the support assembly 1 and a roller blind with one end fixed to the roller 31 and the other end free makes the operation of the side enclosure 3 very convenient. Construction workers only need to rotate the roller 31 to easily roll up or unroll the roller blind, thereby quickly switching the open and covered states of the corresponding side of the work space to flexibly meet the needs for sun shading and ventilation in different construction scenarios. When the roller shutter is wound on the roller shaft 31, the corresponding side of the work space opens, facilitating the entry and exit of construction personnel, material handling, and ventilation and lighting. When the roller shutter is unwound from the roller shaft 31, it effectively blocks sunlight, preventing direct sunlight from hitting the relevant structures in the work space, maintaining the flatness and friction coefficient of the upper and lower bearing plates, and ensuring the smooth progress of the main cable saddle construction. Moreover, this structure occupies little space, and when not in use, the roller shutter is wound on the roller shaft 31, which does not cause too much obstruction to the construction space. At the same time, the structure is simple, the cost is low, and it is easy to install and maintain.
[0068] Furthermore, the free end of the roller blind is equipped with a locking device. When the roller blind is wound on the roller shaft 31, the locking device can be detachably locked to the roller shaft 31; when the roller blind is unwound from the roller shaft 31, the locking device can be detachably locked to the bottom of the working space. When the roller blind is wound on the roller shaft 31, the locking device can be detachably locked to the roller shaft 31, preventing the roller blind from unfolding due to accidental rotation, ensuring that the side of the working space remains open, providing a spacious and unobstructed environment for construction operations, facilitating free passage of construction personnel and material transportation. When the roller blind is unwound from the roller shaft 31 to cover the side of the working space, the locking device can be detachably locked to the bottom of the working space, firmly fixing the roller blind and preventing it from swaying or retracting due to external forces such as wind, ensuring that the roller blind can continuously and stably perform its sunshade function, effectively blocking direct sunlight from hitting the relevant structures, and maintaining the environmental conditions required for the main cable saddle construction.
[0069] The locking component is a traction rope 32. When the roller blind is in the unfolded state, the end of the traction rope 32 can be anchored to the lower longitudinal beam 12; when the roller blind is wound on the roller 31, the end of the traction rope 32 can be tied to the upper longitudinal beam 11.
[0070] Alternatively, when the roller shutter is in the unfolded state, the free end of the roller shutter can be temporarily tied to the lower longitudinal beam 12 with thin rope; or, the bottom of the roller shutter can be weighed down with steel or other heavy objects to make the internal working space completely enclosed.
[0071] In other embodiments, the side enclosure 3 may use multiple folding panels connected sequentially by hinges. A fixed shaft is provided on the side of the support component 1, and one end of the side enclosure 3 is hinged to the fixed shaft, allowing the entire enclosure to rotate around the shaft. When the side of the work space needs to be opened, the folding panels are folded up sequentially and placed against the side of the support component 1, occupying minimal space. When covering is required, the folding panels are unfolded sequentially to form a continuous covering surface, effectively covering the side of the work space.
[0072] Alternatively, magnetic strips or plates can be installed on the side of the support assembly 1, and corresponding magnetic materials can be applied to the edges of the side enclosure 3. When the side enclosure 3 approaches the side of the support assembly 1, they attract each other magnetically, causing the side enclosure 3 to adhere to the support assembly 1, thus covering the side of the work space. To open it, simply pull the side enclosure 3 off the support assembly 1.
[0073] It is understandable that the connection method between the side enclosure 3 and the support component 1 is not limited here, as long as it can be ensured that the side enclosure 3 can move relative to the support component 1 to achieve the effect of opening or covering the side of the working space.
[0074] The operation cycle of the shading equipment is from the completion of the UHPC pouring inside the grid to the hoisting of the saddle body. Therefore, before hoisting the lower support plate, the roller system, and the upper support plate box, the top cover 2 needs to be slid and retracted to one side so that the hoisting components can be directly lowered and installed from directly above. After installation, the top cover 2 should be unfolded in a timely manner.
[0075] Shading equipment provides rain and wind protection, preventing sunlight from deforming the grille. However, severe weather conditions such as strong winds, heavy rain, and heavy snow may occur during construction. Therefore, the shading equipment needs to withstand wind and snow loads. But if the shading equipment is to withstand these loads directly, the design will inevitably be uneconomical. Therefore, the design of the shading equipment only needs to consider winds below level 6 and resistance to light rain.
[0076] According to the weather forecast, before the arrival of severe weather, the top canopy 2 needs to be slid and retracted to one side, the roller shutters need to be fully rolled up and secured with thin ropes, and a temporary tarpaulin needs to be laid over the construction area and secured.
[0077] When it is necessary to remove the sunshade equipment, first remove the top cover 2. During removal, first release the lock on the sliding of the top cover 2, then push the top cover 2 so that it slides along the I-beam 4 on the top of the support assembly 1. Move the top cover 2 to a position that is easy to move and then remove it to complete the removal of the top cover 2.
[0078] Next, remove each side enclosure 3 in sequence. During removal, first unlock the locking piece at the free end of the roller shutter from the bottom of the work space, then manually pull the free end of the roller shutter to gradually wind it onto the roller shaft 31. Once the roller shutter is fully wound, remove the connecting parts between the roller shaft 31 and the support assembly 1, and remove the roller shutter as a whole.
[0079] Next, remove the crossbeam 13. During removal, loosen the connecting bolts or other connecting parts between the crossbeam 13 and the upper longitudinal beam 11 and the lower longitudinal beam 12, and remove the crossbeam 13 one by one. After the crossbeam 13 is removed, disconnect the fixed connection between the column 14 and the top of the construction tower 100.
[0080] Next, dismantle the supporting structure on one side. During dismantling, the upper longitudinal beam 11, lower longitudinal beam 12, column 14, and diagonal brace on one side are dismantled as a whole. Since they form a stable structure through welding, bolting, and other methods, the connections between the components are removed first, and then the upper longitudinal beam 11, lower longitudinal beam 12, column 14, and diagonal brace on that side are dismantled sequentially or as a whole by hoisting.
[0081] Finally, dismantle the supporting structure on the other side. Using the same method as dismantling the supporting structure on one side, dismantle the upper and lower longitudinal beams 12, columns 14, and diagonal braces on the other side. At this point, the sunshade equipment has been completely dismantled.
[0082] It is understandable that when it is necessary to install sunshade equipment, the installation process is the reverse of the above-mentioned removal process, which will not be elaborated here.
[0083] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
