Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic dam slope shading, and more particularly to an assembled shading structure and a construction method thereof. Background Art

[0002] In a pumped-storage power station, an asphalt concrete panel is often laid on the dam slope surface to improve the anti-seepage capacity of the dam. In the northwest region of China, due to long sunshine hours and high intensity, some power stations will face the extreme weather environment of long-term exposure to the sun. Excessive high-temperature exposure will cause the asphalt concrete to soften and flow, thus having an adverse impact on the mechanical properties and anti-seepage effect of the asphalt concrete anti-seepage plate, resulting in safety problems during the operation of the dam and the power station and thus suffering economic losses. Nowadays, a method of using an assembled sunshade to shade the dam slope has emerged, reducing the time of direct sunlight on the panel and preventing the asphalt concrete panel from losing its anti-seepage ability due to high-temperature exposure.

[0003] In the related art, a prefabricated sunshade is fixedly installed on the dam crest. The sunshade is in an inverted L shape and mainly consists of an inverted L-shaped side frame connected to the dam body, a ceiling frame installed between adjacent side frames, and a shed cover with rain-proof and sun-shading functions.

[0004] However, in the related art, welding construction is used for each part component of the assembled sunshade. Therefore, the construction quality highly depends on the professional skill level of the welder and cannot be completed by general workers, thus raising the employment standard and increasing the construction difficulty of the sunshade. Moreover, too many welding parts will also make it difficult for the prefabricated components to be recycled repeatedly after disassembly and modification, which is not conducive to energy conservation and environmental protection. Summary of the Invention

[0005] The problem solved by the present invention is how to reduce the construction difficulty of the assembled hydraulic sunshade and at the same time improve the repeated utilization rate of the prefabricated components.

[0006] To solve the above problems, the present invention provides an assembled shading structure and a construction method thereof.

[0007] In a first aspect, the present invention provides an assembled shading structure, adopting the following technical solution:

[0008] An assembled shading structure includes a prefabricated overhanging shed frame, a sliding support member, and a sunshade panel. The prefabricated overhanging shed frame includes a support column and a horizontal overhanging beam connected to each other. A plurality of prefabricated overhanging shed frames are arranged at intervals along a set direction. A plurality of the sliding support members are connected to the horizontal overhanging beam of the prefabricated overhanging shed frame and can slide along the extending direction of the horizontal overhanging beam. The sunshade panel is laid flat between the horizontal overhanging beams of adjacent prefabricated overhanging shed frames and is supported by the sliding support members.

[0009] The beneficial effects of the present invention are as follows: multiple sliding supports are slidably connected to the horizontal cantilever beams of the prefabricated cantilever scaffolding, and the sliding supports spaced apart on the horizontal cantilever beams are in direct contact with the sun visors and bear the load. The sliding of the sliding supports after bearing the load is restricted, so that the weight of the sun visors can be used to keep the sliding supports in a stable and stationary state during later use. During the construction process, the sliding supports are highly versatile and can accommodate sun visors of different sizes by adjusting the spacing between two adjacent sliding supports through sliding. The flat sun visors can be installed quickly and stably without the use of additional fixing devices, thereby speeding up the construction speed. In case of dismantling and modification during later use, after removing the sun visors, the sliding supports will resume their sliding function and can be easily removed by sliding the sliding supports to the end of the prefabricated cantilever scaffolding.

[0010] Compared to traditional welding fixation, the visor and sliding supports remain structurally intact after removal, allowing them to be recycled and reused in other awning construction projects without requiring remanufacturing. This significantly reduces the assembly difficulty of prefabricated awnings and increases the reuse rate of prefabricated components, making them environmentally friendly and in line with future architectural trends.

[0013] Optionally, the horizontal cantilever beam includes a module beam section and a connector, and a plurality of the module beam sections are sequentially spliced together through the connector, and the length of the module beam section is consistent with the side length of the sun visor in the span direction.

[0015] Optionally, the prefabricated overhang scaffold further includes a cable, with both ends of the cable being fixed to the support column and the connecting member respectively.

[0016] Optionally, the support column includes a column, a beam and a corbel, the bottom end of the column is fixedly connected to the hydraulic structure, a horizontal through-mounting hole is opened on the column, the beam is passed through the mounting hole, and the beam is divided into a load-bearing section and a balancing section with the column as the boundary, the load-bearing section is used to connect the horizontal cantilever beam, the corbel is supported below the load-bearing section and the corbel is fixedly connected to the column.

[0017] Optionally, a side edge of the sun visor presses against the mounting portion.

[0019] In a second aspect, the present invention provides a construction method for an assembled sunshade structure, which adopts the following technical solution:

[0039] The present invention provides an assembled sunshade structure and a construction method thereof.

[0040] Referring to Figure 1 , Figure 2 , an assembled sunshade structure provided by an embodiment of the present invention includes a prefabricated overhanging shed frame 1, a sliding support member 2, and a sunshade panel 3. The prefabricated overhanging shed frame 1 includes a support column 11 and a horizontal overhanging beam 12 that are connected to each other. A plurality of prefabricated overhanging shed frames 1 are arranged at intervals along a set direction. A plurality of the sliding support members 2 are connected to the horizontal overhanging beam 12 of the prefabricated overhanging shed frame 1 and can slide along the extending direction of the horizontal overhanging beam 12. The sunshade panel 3 is laid flat between the horizontal overhanging beams 12 of adjacent prefabricated overhanging shed frames 1 and is supported by the sliding support member 2.

[0041] Specifically, the prefabricated overhanging shed 1 includes a vertical support column 11 and a horizontal overhanging beam 12, which can be specifically in the shape of an inverted L-shaped bracket. Multiple sunshade panels 3 are laid flat between two prefabricated overhanging sheds 1 placed side by side to form a single-span sunshade structure, and the number of spans required is determined according to the length of the dam body and the length of a single span. A plurality of sliding support members 2 are slidably connected to the horizontal overhanging beam 12 of the prefabricated overhanging shed 1. The sliding support members 2 located on both sides of the sunshade panel 3 are in direct contact with the sunshade panel 3 and bear the load. After bearing the load, the sliding of the sliding support members 2 is restricted, so that the self-weight of the sunshade panel 3 can be used to keep the sliding support members 2 in a stable and stationary state during the later use process. During the construction process, the sliding support members 2 have strong versatility. By sliding and adjusting the distance between two adjacent sliding support members 2, sunshade panels 3 of different sizes and specifications can be adapted. The laid sunshade panels 3 can be quickly and stably installed without using additional fixing devices, thus accelerating the construction speed. During the later use process, if demolition and modification are required, after removing the sunshade panel 3, the sliding support members 2 resume their sliding function, and the sliding support members 2 can be easily removed by sliding them to the end of the horizontal overhanging beam 12.

[0042] Compared with the traditional welding fixation in the related art, after demolition, the sunshade panel 3 and the sliding support members 2 can still maintain their structural integrity and can be directly recycled without being remelted, and can be reused in the construction of sunshades for other projects. The assembly difficulty of the assembled sunshade is greatly reduced, and at the same time, the reuse rate of prefabricated components is improved. It is green and environmentally friendly, meeting the development trend of future buildings.

[0043] Refer to Figure 2 In this embodiment, the sunshade panel 3 is preferably a rectangular panel with a unified specification. The X direction is the span direction of the sunshade panel 3. The sliding support members 2 and the sunshade panel 3 adopt a four-point support force form, and a sliding support member 2 is provided at each of the four corner points of each sunshade panel 3. The above support method is more conducive to the lightweight design of the sliding support members 2, facilitating the installation by workers and reducing the labor intensity of workers.

[0044] Refer to Figure 1 The overall sunshade structure takes two prefabricated overhanging sheds 1 and the sunshade panels 3 laid between them as one span. In this embodiment, a seven-span assembled sunshade structure is adopted, and the number of spans of the sunshade panels 3 is six spans.

[0045] Optionally, the sunshade panel 3 is a solar power generation panel.

[0046] Specifically, most of the hydraulic structures 10 that need to be provided with sunshade structures are located in areas with sufficient sunlight. Using a solar power generation panel as the sunshade panel 3 can utilize solar energy while shading the dam slope 102. The sunshade panel 3 can generate electricity using solar energy to supply supporting living facilities such as street lights in the dam, reducing commercial electricity consumption and the operation cost of the dam.

[0047] Refer toFigure 3 Optionally, the sliding support member 2 includes a mounting portion 21, a sliding portion 22 and a supporting portion 23, the sliding portion 22 is fixedly connected to the mounting portion 21, the sliding portion 22 is in rolling contact with the horizontal cantilever beam 12, and the supporting portion 23 is fixedly connected to the side of the mounting portion 21 away from the sliding portion 22, and the supporting portion 23 is used to place the sun visor 3.

[0048] Specifically, the sliding portion 22 and the supporting portion 23 are respectively arranged on both sides of the mounting portion 21 , which can effectively separate the sliding function and the supporting function of the sliding support member 2 to avoid blocking and interfering with each other.

[0049] In this embodiment, the mounting portion 21 and the supporting portion 23 are both rectangular plates. The supporting portion 23 is vertically fixed to the side of the mounting portion 21 facing away from the sliding portion 22. The side of the supporting portion 23 that abuts against the sun visor 3 is parallel to the XY plane. The right angle formed by the mounting portion 21 and the supporting portion 23 is beneficial to the positioning of the sun visor 3 during installation and maintaining stability after installation.

[0050] The sliding portion 22 may include a fixing member 221 and a roller 222. The roller 222 is coaxially connected to the fixing member 221 via a pin. A screw is fixedly connected to the side of the fixing member 221 facing away from the roller 222. A corresponding threaded hole is provided on the mounting portion 21. The screw and the threaded hole cooperate to achieve a fixed connection between the sliding portion 22 and the mounting portion 21. Using the roller 222 to roll along the overhanging portion of the prefabricated overhang scaffolding 1 to achieve overall sliding of the sliding support 2 can make the sliding process smoother and further reduce the difficulty of installation. Preferably, two rows of sliding portions 22 are provided on the upper and lower sides of the mounting portion 21, with two in each row, so as to limit the relative displacement in the Z direction between the sliding support 2 and the prefabricated overhang scaffolding 1, improve the connection strength, and enhance the sliding stability.

[0051] Optionally, a side edge of the sun visor 3 is pressed against the mounting portion 21 .

[0052] Specifically, the two sides of the sun visor 3 supported by the sliding support member 2 serve as limiting edges, while the two sides of the sun visor 3 perpendicular to the limiting edges serve as free edges. By ensuring that the clearance between the two opposing mounting portions 21 is slightly less than the length of the free edges of the sun visor 3, the sun visor 3 and the sliding support member 2 are connected and engaged in an elastic snap-fit manner. The mounting portions 21 of the two opposing sliding support members 2 respectively abut against the outer wall of the sun visor 3 from both sides. In addition to their limiting function, the mounting portions 21 also serve to strengthen the connection, enhancing structural stability.

[0053] Reference Figure 1, optionally, the horizontally cantilevered beam 12 is a spliced beam, the support column 11 is used for anchoring with the hydraulic structure 10, one end of the spliced beam is detachably fixed to the support column 11, and the other end of the spliced beam horizontally cantilevers towards the dam slope 102 side, so that the positive projection range of the sunshade 3 on the slope of the dam slope 102 covers the dead water line, and the sliding support member 2 is slidably connected to the spliced beam.

[0054] Specifically, in the related art, the cantilever beam and the load-bearing column of the sunshade frame are both single-piece integral components, and large hoisting equipment is required for construction during on-site assembly and welding. In the hydraulic structure 10, the sunshade cantilevers towards the dam slope 102, and the slope surface cannot provide free movement for the hoisting equipment, and the weight of the integral steel component far exceeds the limit of human load. The horizontally cantilevered beam 12 is improved to be a spliced beam, and the weight of each section of the spliced beam is controlled within the range that is convenient for manual handling and installation, so that large hoisting equipment is not required. A small ladder is installed on the dam top 101, and the ladder transports workers and prefabricated components to the required position height, and the workers can install them manually, which simplifies the use of construction equipment, reduces the conditions required for installing the sunshade frame, and thus reduces the construction economic cost. When the water level drops to the dead water line, it is the time when the exposed area of the dam slope 102 is the largest. The dead water line of the hydraulic structure 10 being within the positive projection range of the sunshade 3 on the slope of the dam slope 102 can ensure that the sunshade structure plays a sun protection and shading role for the dam slope 102 throughout the whole cycle, all time periods, and all water levels.

[0055] Refer to Figure 4 , optionally, the horizontally cantilevered beam 12 includes modular beam segments 121 and connectors 122. Multiple modular beam segments 121 are sequentially spliced through the connectors 122, and the length of the modular beam segment 121 is the same as the side length of the sunshade 3 in the span direction.

[0056] Specifically, by using modular beam segments 121 with the same length as the side length of the sunshade 3 in the span direction, the number of spans of the sunshade 3 and the horizontally cantilevered beam 12 is equal and the edges are aligned, which can further improve the assembly adaptability between the sunshade 3 and the horizontally cantilevered beam 12, facilitate the counting of component quantities, and make the component parameters more unified. The modular beam segments 121 designed with modularity cooperate with the general connectors 122 for connection, which can also facilitate the improvement of the applicable range of the components. During use, the overhanging length of the sunshade structure can be flexibly adjusted according to the water level line.

[0057] Refer to Figure 4 , optionally, a card slot 1211 is opened at the end of the modular beam segment 121, the connector 122 is provided with a protruding clamping portion 1221 outward, and the clamping portion 1221 is in interference fit with the card slot 1211; and / or, a limiting portion 1222 is provided on the connector 122, and the limiting portion 1222 is used for restricting the sliding of the sliding support member 2.

[0058] Specifically, a clamping groove 1211 is formed at the end of the modular beam section 121, and is in plug-in fit with the clamping portion 1221 protruding from the surface of the connecting member 122, so that the connecting member 122 can be hidden inside the modular beam section 121. After splicing, the two modular beam sections 121 can abut against each other, thereby reducing the error between the length of the spliced beam after splicing and the calculated length of the horizontal cantilever beam 12 in actual splicing.

[0059] In this embodiment, the modular beam section 121 is composed of two steel rails. In order to flexibly adjust the length of the modular beam section 121 and make clamping grooves 1211 available at both ends of any length, the clamping grooves 1211 are parallel to the length direction of the steel rails, and two clamping grooves are provided vertically. The clamping grooves 1211 are both formed on one side of the two steel rails facing each other. The main body of the connecting member 122 is a rectangular plate. Through grooves parallel to the sliding direction of the sliding support member 2 are symmetrically formed on both sides of the connecting member 122, and a clamping portion 1221 is formed at each of the upper and lower edges of the through groove. The two clamping portions 1221 are respectively inserted into the two clamping grooves 1211, and the two steel rails are fixed to each other through the connecting members 122 at both ends. This embodiment further improves the assembly degree of the spliced beam, and the component is designed with lightweight, reducing the labor intensity of workers during installation. The double clamping grooves 1211 and the double clamping portions 1221 can improve the connection strength.

[0060] Refer to Figure 5 In other embodiments, it is also possible to fixedly provide limiting portions 1222 on the top surface and the bottom surface of the connecting member 122. In this embodiment, the limiting portions 1222 are formed by vertically splicing two plate members. The four T-shaped limiting portions 1222 are centrally and symmetrically distributed on the top surface and the bottom surface of the connecting member 122, and can play a role in positioning both the sliding support member 2 and the modular beam section 121, so as to prevent the sliding support member 2 from being accidentally pushed by an external force and causing the overall displacement of the sunshade 3 during later use.

[0061] Refer to Figure 1 、 Figure 2 Optionally, the prefabricated cantilever shed 1 further includes a cable 13, and both ends of the cable 13 are respectively fixed to the support column 11 and the connecting member 122.

[0062] Specifically, by providing the cable 13 between the connecting member 122 and the support column 11, the load at the end of the horizontal cantilever beam 12 can be reduced, thereby reducing the flexural deformation of the horizontal cantilever beam 12 caused by gravity, avoiding the overall overturning of the prefabricated cantilever shed 1, and improving the structural stability. Since the lengths of the modular beam sections 121 are equal, the cable 13 is installed through the connecting members 122 at equal intervals, and the force on the horizontal cantilever beam 12 can also be evenly distributed.

[0063] Refer to Figure 2 、 Figure 6, in this embodiment, a cable hole 1223 perpendicular to the X-Y plane is formed in the center of the connecting member 122, and a plurality of cable positioning holes 1112 arranged along the Z direction are formed at the top of the outer peripheral wall of the support column 11. The cables 13, the cable positioning holes 1112 and the connecting member 122 correspond to each other one by one. During construction, one end of the cable 13 is first anchored on the support column 11, then the other end of the cable 13 is passed through the cable hole 1223 for tensioning, and finally fixed. The connecting member 122 closest to the support column 11 corresponds to the lowermost cable positioning hole 1112. The farther the connecting member 122 is from the support column 11, the higher the position of the corresponding cable positioning hole 1112 connected. During installation, it is necessary to avoid the cables 13 from crossing and knotting with each other.

[0064] Referring to Figure 6 , Figure 7 , optionally, the support column 11 includes a column 111, a beam frame 112 and a bracket 113. The bottom end of the column 111 is fixedly connected to the hydraulic structure 10. A horizontally penetrating installation hole 1111 is formed in the column 111. The beam frame 112 is inserted into the installation hole 1111. The beam frame 112 is divided into a load-bearing section 1121 and a balancing section 1122 with the column 111 as the boundary. The load-bearing section 1121 is used to connect the horizontally cantilevered beam 12. The bracket 113 is supported below the load-bearing section 1121 and the bracket 113 is fixedly connected to the column 111.

[0065] Specifically, the setting of the bracket 113 plays an auxiliary supporting role for the beam frame 112, which can reduce the calculated length of the cantilever part of the beam frame 112 and improve the bearing capacity of the beam frame 112. The load-bearing section 1121 of the beam frame 112 is fixedly connected to the cantilever starting end of the horizontally cantilevered beam 12, and welding or bolt connection can be selected. The balancing section 1122 of the beam frame 112 can play a role in counterweight to balance the force of the load-bearing section 1121. Making the balancing section 1122 into an arc shape can also play a role in limiting, avoiding the beam frame 112 from slipping in the direction of the dam slope 102 due to excessive force on the load-bearing section 1121. In order to improve the connection strength between the beam frame 112 and the column 111, it is preferably to weld the contact part between the beam frame 112 and the column 111 from the outside, and a circumferential seal weld connected end to end is preferably adopted.

[0066] In this embodiment, the beam frame 112 and the modular beam section 121 are preferably fixed by a bolt anchoring connection method. The beam frame 112 is made of a box-section steel profile with flanges. During installation, bolt holes are correspondingly formed in the first modular beam section 121 and the side wall of the beam frame 112, then the modular beam section 121 is inserted into the cavity of the box-section steel profile and the modular beam section 121 is fitted to the inner wall of the cavity. Screws are inserted into the bolt holes and horizontally penetrate through the beam frame 112, and finally nuts are used to fix the protruding sections of the screws.

[0068] The method includes:

[0070] When pouring the hydraulic structure 10, reserve anchor holes 1011 in the dam crest 101, insert the support columns 11 of each precast overhanging pergola 1 into the anchor holes 1011 in sequence, and connect and fix the support columns 11 of the precast overhanging pergola 1 to the hydraulic structure 10.
