Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic panel installation structure technology, specifically a large-span flexible support end installation structure under site constraints. Background Technology

[0002] For wastewater treatment plants with limited space, the end columns of large-span flexible supports are usually installed on the walls of the wastewater treatment pool. The area around the pool is the daily maintenance road of the wastewater treatment plant. Due to the limited space, the anchoring end is generally composed of two U-shaped pull rings, steel strands, diagonal fasteners, and reinforced concrete load-bearing piles (one column and one pile), as shown in "A New Type of Flexible Photovoltaic Support" with publication number CN220754704U.

[0003] The anchorage end of the large-span flexible support bears the entire structural weight, wind load and dynamic load. If it encounters extreme weather (such as freezing rain or snow), it is easy to cause damage to the inclined fasteners, the reinforced concrete load-bearing piles to be pulled up, and thus the large-span flexible support system to collapse. Utility Model Content

[0004] This utility model provides an end installation structure for large-span flexible supports under site constraints, aiming to solve the problem that existing flexible support side fixing structures are easily pulled up and cause the flexible support system to collapse when encountering severe weather in situations with limited installation space.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An end-mounting structure for a large-span flexible support under site constraints, the installation structure includes several installation groups, each installation group includes several installation units, and each installation unit corresponds one-to-one with a flexible support end column on the flexible support mounting wall;

[0007] Each installation group includes a load-bearing main beam. The flexible support mounting wall has a continuous mounting groove on one side. The load-bearing main beam is embedded and confined within the mounting groove. The installation units in the same group are all supported and fixed on the corresponding load-bearing main beam.

[0008] Each installation unit includes a support component mounted on the main load-bearing beam. The support component and the main load-bearing beam work together to form a multi-layered hollow structure. The top of the support component is connected to the top of the corresponding flexible support end column through a diagonal support component.

[0009] Preferably, there are no fewer than three installation units within the same installation group.

[0010] More preferably, each of the inclined support components includes inclined steel columns arranged at an angle toward the mounting groove. The top of the inclined steel column is fixedly installed to the wing plate at the top of the corresponding flexible support end column by fixing bolts, and the bottom of the inclined steel column is fixedly installed to the top of the corresponding top layer connecting beam by expansion bolts.

[0011] Furthermore, the supporting component includes several layers of connecting beams arranged in a vertical direction. Adjacent connecting beams are supported and fixed by several short columns, and the bottom of the lowest connecting beam is supported and fixed to the main load-bearing beam by several short columns.

[0012] Furthermore, the connecting beam has at least two layers. The first layer of connecting beam is supported and fixed to the second layer of connecting beam by a number of short columns, and the short columns of this layer are symmetrical about the bottom middle position of the first layer of connecting beam. The second layer of connecting beam is supported and fixed to the corresponding load-bearing main beam by a number of short columns.

[0013] Specifically, both the connecting beam and the load-bearing main beam are quadrangular prism-shaped reinforced concrete columns, and the horizontal area of ​​the connecting beam gradually increases in the vertical upward direction.

[0014] More specifically, the bottom of the load-bearing main beam and the corresponding support component are provided with a number of limiting posts. The limiting posts are driven into the bottom of the installation groove, and the load-bearing main beam forms a limiting fit with the installation groove through the limiting posts.

[0015] In detail, both the connecting beam and the load-bearing main beam have inclined surfaces on the side away from the corresponding flexible support end column, and the inclined surfaces slope downward along the side away from the corresponding flexible support end column.

[0016] More specifically, the adjacent load-bearing main beams are coaxially connected by connectors.

[0017] Preferably, the installation groove is filled with soil, which covers the main load-bearing beam and the supporting components, and the soil presses down on the slope to limit its movement.

[0018] The beneficial effects of this utility model are:

[0019] 1. Multiple installation units are assembled into an installation group and installed on the same load-bearing main beam to increase the self-weight of the load-bearing main beam, thereby improving its pull-out resistance after being buried in soil.

[0020] 2. All installation units use diagonal bracing components to support and limit the top of the corresponding flexible support column. The self-weight of the supporting components and the main beam resists pull-out and prevents them from being pulled up.

[0021] 3. The supporting components and the main load-bearing beams work together to form a multi-layer hollow structure. On the one hand, this avoids completely blocking the underground structure of the sewage treatment plant pool, which would affect future maintenance needs and saves horizontal installation space, making it suitable for narrower locations. On the other hand, when the soil is buried, the soil fills into the hollow structure, creating resistance to the connecting beams of each layer and improving the overall tensile strength.

[0029] The embodiments will be further described below with reference to the accompanying drawings.

[0030] like Figures 1-3 As shown in the preferred embodiment 1, a large-span flexible support end installation structure under site constraints is provided. The installation structure includes several installation groups, each installation group includes several installation units, and each installation unit corresponds one-to-one with the flexible support end column 1 on the flexible support installation wall 8.

[0031] Each installation group includes a load-bearing main beam 4. The flexible support mounting wall 8 has a continuous mounting groove 7 on one side. The load-bearing main beam 4 is embedded and confined within the mounting groove 7. The installation units in the same group are all supported and fixed on the corresponding load-bearing main beam 4.

[0032] Each installation unit includes a support component 3 mounted on the main load-bearing beam 4. The support component 3 and the main load-bearing beam 4 work together to form a multi-layer hollow structure. The top of the support component 3 is connected to the top of the corresponding flexible support end column 1 through a diagonal support component 2.

[0033] Multiple installation units are assembled into an installation group and installed on the same load-bearing main beam 4 to increase the self-weight of the load-bearing main beam 4, thereby improving its pull-out resistance after being buried in soil.

[0034] Each installation unit supports and limits the top of the corresponding flexible support end column 1 through the inclined support component 2, and resists pull-out by the self-weight of the bearing component 3 and the load-bearing main beam 4 to prevent it from being pulled up.

[0035] The supporting component 3 and the main load-bearing beam 4 work together to form a multi-layer hollow structure. On the one hand, this avoids completely blocking the underground structure around the sewage treatment plant pool, which would affect future maintenance needs. On the other hand, when the soil is buried, the soil fills into the hollow structure, creating resistance to the connecting beams of each layer and improving the overall tensile strength.

[0036] There should be no fewer than three installation units within the same installation group. Ensure they are under their own weight to prevent them from being pulled up.

[0037] Each of the inclined support components 2 includes inclined steel columns 201 arranged at an angle towards the mounting groove 7. The top end of the inclined steel column 201 is fixedly installed to the wing plate 101 at the top end of the corresponding flexible support end column 1 by fixing bolts 202. The bottom end of the inclined steel column 201 is fixedly installed to the top of the corresponding top-level connecting beam 301 by expansion bolts 203. This ensures the fixed installation of the inclined steel column 201, limits the position of the flexible support end column 1, and prevents the flexible support end column 1 from being pulled up after cooperating with the supporting component 3 and the load-bearing main beam 4.

[0038] The supporting component 3 includes several layers of connecting beams 301 arranged vertically. Adjacent connecting beams 301 are supported and fixed by several short columns 302. The bottom connecting beam 301 is supported and fixed to the main load-bearing beam 4 by several short columns 302. The hollow structure ensures improved tensile strength after being buried by soil.

[0039] The connecting beams 301 consist of at least two layers. The first layer of connecting beams 301 is supported and fixed to the second layer of connecting beams 301 by a number of short columns 302. The short columns 302 in this layer are symmetrical about the bottom middle position of the first layer of connecting beams 301. The second layer of connecting beams 301 is supported and fixed to the corresponding load-bearing main beams 4 by a number of short columns 302. This ensures the stability of the structure.

[0040] After drilling the installation holes for the short column 302 on the connecting beam 301, insert the short column 302 and seal and fix it with concrete.

[0041] Both the connecting beam 301 and the load-bearing main beam 4 are quadrangular prism-shaped reinforced concrete columns. The horizontal area of ​​the connecting beam 301 gradually increases in the vertical upward direction, forming a leaning tower structure, increasing the soil's load-bearing area and improving tensile strength.

[0042] The load-bearing main beam 4 and the supporting component 3 are provided with several limiting posts 5 at their bottoms. The limiting posts 5 are driven into the bottom of the mounting groove 7, and the load-bearing main beam 4 forms a limiting fit with the mounting groove 7 through the limiting posts 5. This increases the tensile strength and stability of the device.

[0043] After drilling the installation holes for the limiting columns 5 on the main load-bearing beam 4, insert the limiting columns 5 and seal and fix them with concrete.

[0044] As a preferred embodiment 2, the connecting beams 301 are distributed sequentially from top to bottom. The uppermost connecting beam 301 is partially exposed above the ground and is fixed to the inclined steel column 201 by expansion bolts 203. Two rows of short columns 302 are provided under this layer of connecting beams 301, with three short columns 302 evenly spaced in each row, which are fixed together with the lower connecting beam 301. Two rows of four short columns 302 (a total of eight) are provided under the second layer of connecting beams 301 and are fixed together with the load-bearing main beam 4. Two rows of four (a total of eight) limiting columns 5 are provided under the corresponding positions of the load-bearing main beam 4 and inserted into the installation groove 7.

[0045] When the connecting beam 301 is being poured, the pouring guide pipe is tied together with the reinforcing steel and placed into the borehole. The distance from the end of the pouring guide pipe to the fixed end face layer is not less than 100mm. During grouting, pure cement grout with a water-cement ratio of 0.5 is used. The grout outlet of the grouting pipe should be inserted 300-500mm from the bottom of the hole. The grout is continuously poured from bottom to top, and it is ensured that the water and air are drained and vented smoothly from the hole. The grouting equipment should have sufficient grout production capacity and the required rated pressure. The grouting pipe used should be able to complete the continuous grouting of a single column within 1 hour.

[0046] Ordinary Portland cement is used for grouting the connecting beam 301 and the long and short columns.

[0047] For strength testing of both long and short columns, there should be at least one set of test blocks for every 30 columns, with each set containing at least 6 test blocks. The strength of the test blocks should meet the design requirements and be no less than 32.5 MPa.

[0048] After the long column pull-out test is passed, construction work will proceed in sequence.

[0049] The area within 600mm on both sides of the top connecting beam 301, which connects to the diagonal steel column 201, is a stirrup reinforcement zone.

[0050] All bolt fixing parts are treated with 8.8 grade hot-dip galvanizing for corrosion protection.

[0051] In a preferred embodiment 3, adjacent load-bearing main beams 4 are coaxially connected by connectors. The connectors can be made of reinforcing steel bars, connecting all the load-bearing main beams 4 to form a line, linking the installation assembly together to form a single, fixed structure. This increases the device's self-weight while significantly enhancing its tensile strength, creating a modular structure that saves space and is suitable for confined spaces.

[0052] As a preferred embodiment 4, both the connecting beam 301 and the load-bearing main beam 4 are provided with inclined surfaces 6 on the side away from the corresponding flexible support end column 1, and the inclined surfaces 6 slope downward along the side away from the corresponding flexible support end column 1.

[0053] The mounting groove 7 is filled with soil, which covers the main load-bearing beam 4 and the supporting component 3, and the soil presses down on the inclined surface 6 to limit its movement. When the device tends to be pulled upwards, the soil will exert a reaction force on each inclined surface 6, increasing its pull-out resistance.

[0054] Greenery can be planted on the soil to ensure aesthetic appeal.

[0055] As a preferred embodiment 5, the main beam 4 and the supporting component 3 can also be selected to be cast and installed on site from bottom to top. During the installation process, all the limiting columns 5 are first cast and installed on site using molds and steel bars, and then inspected.

[0056] After acceptance, the supporting main beam 4 is cast and installed on the limiting column 5 using molds and steel bars to ensure a tight connection between the supporting main beam 4 and the limiting column 5, and then the acceptance is carried out.

[0057] After acceptance, the lowest short column 302 is cast and installed on the main beam 4 using molds and steel bars to ensure a tight connection between the short column 302 and the main beam 4, and then the acceptance is carried out.

[0058] After passing the acceptance test, the connecting beam 301 was cast and installed on the short column 302 on site using molds and steel bars to ensure a tight connection between the connecting beam 301 and the short column 302, and then the acceptance test was conducted.

[0059] Repeat the last two steps until the last connecting beam 301 is poured. After acceptance, the pouring and installation of the entire component are completed.

[0060] As a preferred embodiment 6, the bottom of the main beam 4 is provided with several limiting posts 5, which are not limited to the positions corresponding to the supporting components 3, thus enhancing the overall limiting effect.

[0061] The working principle of this utility model:

[0062] Multiple installation units are assembled into an installation group and installed on the same load-bearing main beam 4 to increase the self-weight of the load-bearing main beam 4, thereby improving its pull-out resistance after being buried in soil.

[0063] Each installation unit supports and limits the top of the corresponding flexible support end column 1 through the inclined support component 2, and resists pull-out by the self-weight of the bearing component 3 and the load-bearing main beam 4 to prevent it from being pulled up.

[0064] The supporting component 3 and the main load-bearing beam 4 work together to form a multi-layer hollow structure. On the one hand, this avoids completely blocking the underground structure around the sewage treatment plant pool, which would affect future maintenance needs. On the other hand, when the soil is buried, the soil fills into the hollow structure, creating resistance to the connecting beams of each layer and improving the overall tensile strength.
