Description

Technical Field

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

[0002] In pumped storage power stations, asphalt concrete panels are 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 extreme weather environments of long-term exposure to the sun, especially in Xinjiang region. Excessive high-temperature exposure will cause the asphalt concrete to soften and flow, which will have 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 power station and thus economic losses. Nowadays, a method of using an assembled sunshade to shield the dam slope has emerged, reducing the time of direct sunlight on the panel and avoiding the loss of anti-seepage ability of the asphalt concrete panel 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 rainproof and sunshading functions.

[0004] However, in the related art, welding construction is used for each component of the assembled sunshade. Therefore, the construction quality highly depends on the professional skill level of welders and cannot be completed by general workers, which improves the employment standard and increases the construction difficulty of the sunshade. Moreover, too many welding parts will also make it difficult to recycle the prefabricated components 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 reuse rate of prefabricated components.

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

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

[0008] 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, and the sliding of the sliding supports after bearing the load is limited, so that the weight of the sun visors can be used to keep the sliding supports in a stable and static state during later use. During the construction process, the sliding supports are highly versatile, and can adapt to sun visors of different sizes and specifications by sliding to adjust the spacing between two adjacent sliding supports. The flat sun visors can be quickly and stably installed without the use of additional fixing devices, thereby speeding up the construction speed. In the event of dismantling and modification during later use, after the sun visors are removed, the sliding supports resume the sliding function, and can be easily removed by sliding the sliding supports to the end of the prefabricated cantilever scaffolding.

[0009] Compared with the traditional welding fixation in related technologies, the dismantled sunshade and sliding support can still maintain the intact structure, and can be directly recycled without remaking, and re-invested in the construction of sunshade awnings for other projects. The assembly difficulty of the assembled sunshade is greatly reduced, and the reuse rate of prefabricated components is increased at the same time. It is green and environmentally friendly, and in line with the development trend of future buildings.

One end of the spliced ​​beam is detachably fixed to the support column, and the other end of the spliced ​​beam is horizontally cantilevered toward one side of the dam slope, so that the sunshade covers the dead water line within the range of the positive projection of the dam slope surface, and the sliding support is slidably connected to the spliced ​​beam.

[0012] 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 support column includes a vertical column, a beam frame and a bracket. The bottom end of the vertical column is fixedly connected to the hydraulic structure. A horizontally penetrating installation hole is formed in the vertical column. The beam frame is inserted into the installation hole.

[0032] The present invention provides a prefabricated sunshade structure and a construction method thereof.

[0033] Referring to Figure 1 、 Figure 2 As shown in, a prefabricated 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 which are connected to each other. A plurality of prefabricated overhanging shed frames 1 are arranged at intervals in 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.

[0034] Specifically, the prefabricated overhanging shed 1 includes a vertical support column 11 and a horizontal overhanging beam 12, which can specifically be 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 one-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 static state during later use. 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 later use, 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.

[0035] 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 a complete structure and can be directly recycled without being remelted and reused, and can be reinvested in the construction of sunshades for other projects. This greatly reduces the assembly difficulty of the prefabricated sunshade and at the same time improves the reuse rate of prefabricated components, which is green and environmentally friendly and conforms to the development trend of future buildings.

[0036] 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.

[0037] 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 prefabricated sunshade structure is adopted, and the number of spans of the sunshade panels 3 is six spans.

[0038] Optionally, the sunshade panel 3 is a solar power generation panel.

[0039] 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 achieving the shading of the dam slope 102. The sunshade panel 3 can generate electricity using solar energy to supply supporting living facilities such as street lamps in the dam, reducing commercial electricity consumption and the operation cost of the dam.

[0040] Refer toFigure 3 , optionally, the sliding support member 2 includes a mounting portion 21, a sliding portion 22 and a support 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 overhanging beam 12. The support portion 23 is fixedly connected to the side of the mounting portion 21 facing away from the sliding portion 22, and the support portion 23 is used to place the sunshade 3.

[0041] Specifically, by arranging the sliding portion 22 and the support portion 23 on both sides of the mounting portion 21 respectively, the sliding function and the support function of the sliding support member 2 can be effectively separated, avoiding mutual shielding and interference.

[0042] In this embodiment, both the mounting portion 21 and the support portion 23 are rectangular plate members. The support portion 23 is vertically fixed to the surface of the mounting portion 21 facing away from the sliding portion 22. The surface of the support portion 23 in contact with the sunshade 3 is parallel to the X-Y plane. The right angle formed by the enclosure of the mounting portion 21 and the support portion 23 is beneficial to the positioning during the paving of the sunshade 3 and maintaining stability after paving.

[0043] The sliding portion 22 may include a fixing member 221 and a roller 222. The roller 222 is coaxially rotatably connected to the fixing member 221 through a pin shaft. A screw is fixedly connected to the surface of the fixing member 221 facing away from the roller 222. A threaded hole is correspondingly formed on the mounting portion 21. The cooperation between the screw and the threaded hole realizes the fixed connection between the sliding portion 22 and the mounting portion 21. The overall sliding of the sliding support member 2 is realized by the rolling of the roller 222 along the overhanging part of the prefabricated overhanging shed 1, which can make the sliding process smoother and further reduce the installation difficulty. Preferably, two rows of sliding portions 22 are arranged on the upper and lower sides of the mounting portion 21, two in each row, so as to be able to limit the relative displacement in the Z direction between the sliding support member 2 and the prefabricated overhanging shed 1, improve the connection strength and enhance the sliding stability.

[0044] , optionally, the side edge of the sunshade 3 is tightly abutted against the mounting portion 21.

[0045] Specifically, the two sides of the sunshade 3 supported by the sliding support member 2 are limiting edges, and the two sides of the sunshade 3 perpendicular to the limiting edges are free edges. By making the clear distance between two opposite mounting portions 21 slightly smaller than the length of the free edge of the sunshade 3, the sunshade 3 and the sliding support member 2 can be connected and matched in an elastic clamping manner. The mounting portions 21 of two opposite sliding support members 2 respectively abut against the outer side walls of the sunshade 3 from both sides. In addition to the limiting function, the mounting portion 21 also plays an additional role in enhancing the connection, improving the structural stability.

[0046] Refer to Figure 1Optionally, the horizontal cantilever beam 12 is a spliced ​​beam, the support column 11 is used to anchor to 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 is horizontally cantilevered toward one side of the dam slope 102, so that the sunshade 3 covers the dead water line within the positive projection range of the slope of the dam slope 102, and the sliding support 2 is slidably connected to the spliced ​​beam.

[0047] Specifically, the cantilever beams and load-bearing columns of the sunshade shed in the related art are all single-piece integral components, and large-scale lifting equipment is required for construction during on-site assembly and welding. In the hydraulic structure 10, the sunshade shed is cantilevered toward the dam slope 102, and the slope cannot be freely moved by the lifting equipment, and the weight of the integral steel components far exceeds the human load limit. The horizontal cantilever beam 12 is improved to a spliced ​​beam, and the weight of each section of the spliced ​​beam is controlled within a range that is convenient for manual picking and installation, so there is no need to use large-scale lifting equipment. A small ladder is installed on the dam top 101, and the ladder transports the workers and prefabricated components to the required height, and the workers can install them manually, which simplifies the use of construction equipment and reduces the conditions required for installing the sunshade shed, thereby reducing the economic cost of construction. When the water level drops to the dead water line, the exposed area of ​​the dam slope 102 is the largest. The dead water line of the hydraulic structure 10 is located within the range of the positive projection of the sunshade 3 on the slope of the dam slope 102, which can ensure that the sunshade structure can protect the dam slope 102 from the sun in the whole cycle, all time periods and all water levels.

[0048] Reference Figure 4 Optionally, the horizontal cantilever beam 12 includes a module beam section 121 and a connector 122. A plurality of the module beam sections 121 are sequentially spliced ​​through the connector 122. The length of the module beam section 121 is consistent with the side length of the sun visor 3 in the span direction.

[0049] Specifically, a modular beam section 121 having the same length as the side length in the span direction of the sunshade 3 is used, and the sunshade 3 and the horizontal cantilever beam 12 have the same span and aligned edges, which can further improve the assembly adaptability between the sunshade 3 and the horizontal cantilever beam 12, facilitate the counting of the number of components, and make the component parameters more uniform. The modular beam section 121 with a modular design is connected in coordination with a universal connector 122, which can also facilitate the improvement of the applicable scope of the component. During use, the cantilever length of the sunshade structure can be flexibly adjusted according to the water level.

[0050] Reference Figure 4 Optionally, a slot 1211 is provided at the end of the module beam section 121, and the connecting member 122 is provided with a snap-fitting portion 1221 protruding outward, and the snap-fitting portion 1221 is interference fit with the slot 1211; and / or, a limiting portion 1222 is provided on the connecting member 122, and the limiting portion 1222 is used to limit the sliding of the sliding support member 2.

[0051] 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.

[0052] 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 on the upper and lower sides. 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.

[0053] 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 centered 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.

[0054] 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.

[0055] Specifically, by arranging 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 be evenly dispersed.

[0056] 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. During installation, it is necessary to avoid the cables 13 from crossing and knotting with each other.

[0057] Refer 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 balance 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.

[0058] 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 balance section 1122 of the beam frame 112 can play a role in counterweight and balance the force of the load-bearing section 1121. Making the balance section 1122 into an arc can also play a role in limiting the position, avoiding the beam frame 112 from slipping towards the dam slope 102 direction 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.

[0059] In this embodiment, the beam frame 112 and the module 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 module beam section 121 and the side wall of the beam frame 112, then the module beam section 121 is inserted into the cavity of the box-section steel profile and the module beam section 121 is made to fit with the inner wall of the cavity. The screw is inserted into the bolt hole and horizontally penetrates the beam frame 112, and finally the protruding section of the screw is fixed with a nut.
