Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated cabin foundations, and in particular to a pile-column cast-in-place reinforced concrete single cabin foundation for a prefabricated energy storage battery cabin. Background Art

[0002] In new energy storage projects, the construction of prefabricated cabin equipment foundations faces many challenges. The foundation needs to be built after a large amount of earth excavation and backfilling, especially in bad weather or rainy seasons, which increases the difficulty of construction and the amount of wet work. In addition, in the low temperature environment in winter, special construction measures are required to ensure the quality of the project, which increases the construction period, difficulty and cost. The foundation of prefabricated cabin equipment requires a large amount of steel bars and concrete, resulting in increased material consumption.

[0003] For this purpose, a pile-column-cast reinforced concrete prefabricated single cabin foundation for energy storage batteries is proposed to solve the above-mentioned problems. Summary of the invention

[0004] The present invention aims to provide a pile-column cast-in-place reinforced concrete prefabricated single cabin foundation for energy storage batteries to solve or improve at least one of the above-mentioned technical problems.

[0005] In view of this, a first aspect of the present invention is to provide a pile-column-in-place cast-in-place reinforced concrete prefabricated single cabin foundation for energy storage batteries.

[0006] A second aspect of the present invention is to provide a construction method.

[0007] A first aspect of the present invention provides a pile-column cast-in-place reinforced concrete energy storage battery prefabricated cabin single cabin foundation, comprising: a reinforced concrete foundation, which includes a pile column and a connecting beam integrally formed by concrete pouring; the pile column is arranged in a foundation along a preset direction, and the preset direction is parallel to the connecting surface of the pile column and the connecting beam; the connecting beam connects two pile columns along at least one connecting direction; the pile column and the connecting beam both include a steel cage for supporting the concrete; a plurality of embedded parts, which are inserted on the steel cage of the pile column and / or the connecting beam; the embedded parts include anchor bars and anchor plates, at least a portion of the anchor plates and the anchor bars are embedded in the concrete; along the preset direction, the anchor plate has a welding surface whose height is not lower than that of the pile column and the connecting beam; a connecting part, which is separately arranged from the embedded part; the connecting part has at least one welding belt, and the welding belt is welded and fixed to the welding surface along the preset direction; the connecting part also has an assembly end face separated from the welding belt, and the assembly end face can fix the energy storage battery.

[0008] In any of the above technical solutions, a plurality of casting holes are drilled on the foundation along the preset direction; a prefabricated formwork is assembled on the casting holes to form a casting cavity for casting the concrete; inside the casting cavity, the steel cage of the connecting beam is knotted and fixed with the steel cage of the pile column; the anchor bars are inserted into the steel cage of the connecting beam and / or the steel cage of the pile column.

[0009] In any of the above technical solutions, the connecting member includes: a top plate, the assembly end surface is located on the upper surface of the top plate; two vertical plates are provided and both are connected to the top plate; and the welding belt is located on the lower surface of the vertical plates.

[0010] In any of the above technical solutions, when the welding belt is welded and fixed to the welding surface, the two vertical plates, the top plate and the welding surface together form a buffer cavity; along the welding direction of the welding belt, the two vertical plates and the top plate form a group of hanging holes.

[0011] In any of the above technical solutions, an arc surface is provided on the surface of the vertical plate around the welding band; the arc surfaces of the two vertical plates are arranged opposite to each other; a buffer gap is formed between the arc surface and the welding surface; there is a guide angle between the vertical plate and the top plate, and the numerical range of the guide angle is 91-98; wherein, along the preset direction, the two vertical plates are symmetrically arranged.

[0012] In any of the above technical solutions, the buffer gap is communicated with the buffer cavity.

[0013] In any of the above technical solutions, the number of the connecting parts is equal to the number of the embedded parts; the number of the hanging openings in each group is two, and the two hanging openings are separated and arranged; the two hanging openings in the same group are connected to one buffer cavity, and the two hanging openings and the buffer cavity together constitute a heat dissipation channel.

[0014] In any of the above technical solutions, the heat dissipation channel has a flow direction; on the pile column and the connecting beam, the flow directions of the heat dissipation channel are the same or different.

[0015] In any of the above technical solutions, the direction of the flow direction is set by the center of gravity position of the energy storage battery and the heat dissipation direction of the energy storage battery; with respect to the influence on the direction of the flow direction, the weight of the center of gravity position is higher than the weight of the airflow direction.

[0016] The first aspect of the present invention provides a construction method, comprising the following steps: according to the number of piles required for the energy storage battery, drilling casting holes on the foundation in the same number as the piles; placing the steel cages of the piles and the connecting beams according to the positions of the casting holes, and assembling formwork on the steel cages to form a casting cavity; inserting the anchor bars of the embedded parts on the steel cages, and pouring concrete into the casting cavity; removing the formwork after the concrete solidifies, and fixing the connecting parts to the embedded parts by welding the welding strips and the welding surfaces; and assembling and fixing the assembly end faces of all the connecting parts to the energy storage battery.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The use of cast-in-place reinforced concrete piles and mechanical drilling on site reduces the amount of excavation and backfill compared to conventional practices, speeding up construction, which is particularly critical on construction sites with a relatively short construction window.

[0019] Conventionally, the load of the energy storage battery cabin equipment is transmitted to the reinforced concrete independent foundation or strip foundation through reinforced concrete beams or reinforced concrete walls, and then transmitted to the foundation soil. The present invention adopts a reinforced concrete pile column as a whole, the force transmission path is clearer and more direct, the connection structure is simple, and the construction is convenient.

[0020] Conventional energy storage battery cabin foundation methods use a large amount of reinforced concrete and high engineering costs. Conventional methods use excavation and reinforced concrete extended independent foundations or strip foundations, or box foundation methods similar to basements. The size itself is relatively large, so the amount of concrete used is relatively high. With the pile foundation, the force transmission mode changes, and the load is transmitted by using the friction between the pile and the soil and the end bearing force of the pile end. It is just a section of a cylinder with a relatively small volume and less concrete. The present invention uses a pile-column cast-in-place reinforced concrete foundation, which can save the amount of steel bars and reinforced concrete, save resources, and thus improve energy efficiency and reduce costs.

[0021] The conventional energy storage battery cabin foundation method requires a large workload of supporting formwork, tying reinforcement and pouring concrete, and many of these links need to be completed manually. Conventional methods involve excavation, using reinforced concrete extended independent foundations or strip foundations, or box-type foundations similar to basements. The size itself is relatively large, requiring on-site formwork, tying reinforcement, and pouring concrete. All of these tasks need to be completed manually, and the workload is relatively large. Using pile foundations, mechanical drilling, and the soil itself as a template, only the part above the ground requires formwork, and the underground part does not require separate formwork. For piles, because the steel cages are all the same and have a small size, they can all be completed in the processing plant, then transported to the site, and hoisted into the drilled holes. The volume of the hole is small, and the work of pouring concrete is also relatively small. Therefore, the amount of work for supporting formwork, tying reinforcement and pouring concrete is reduced. In addition, the damage to the site is small. The present invention adopts a pile-column cast-in-place reinforced concrete foundation to reduce the workload of supporting formwork, tying reinforcement and pouring concrete, save labor costs, and improve labor productivity.

[0022] Conventional practice is to bury the full-length channel steel directly on the top surface of the reinforced concrete beam. The channel steel limbs collide with the steel bars in the reinforced concrete beam and need to be cut, which is very inconvenient for construction. The connector for installing the energy storage cabin equipment of the present invention is welded and connected to the steel embedded parts separately in the later stage. The connection node is simple and the construction is convenient. The small steel embedded parts are very convenient to be buried on the top surface of the reinforced concrete beam.

[0023] By establishing a heat dissipation channel, the generated heat can be well dissipated to prevent overheating and damage, so as to reduce the heat transfer to the concrete below and avoid damage to the interior of the concrete due to long-term use. This is especially important for energy storage batteries with heat sources or that need heat dissipation.

DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0037] See also Figure 1-7 , the following describes a pile-column-cast reinforced concrete energy storage battery prefabricated cabin single cabin foundation of some embodiments of the present invention.

[0038] In order to facilitate the grid-connection and peak-shaving of new energy power generation, a large number of energy storage projects are generally provided. Energy storage can be divided into physical energy storage and chemical energy storage. Chemical energy storage includes electrochemical energy storage and other types of chemical energy storage. At present, electrochemical energy storage is the mainstream technology direction, and lithium-ion batteries are the focus of the development of electrochemical energy storage technology. Lithium iron phosphate batteries are the mainstream route. At present, most energy storage projects use lithium iron phosphate electrochemical energy storage technology, integrating several energy storage battery components together and placing them in a prefabricated cabin as a module with a certain rated power. The energy storage battery prefabricated cabin is roughly a rectangular parallelepiped, similar to a container. In large-scale base energy storage projects, there are dozens to hundreds of such prefabricated cabins. The energy storage battery prefabricated cabin must be supported on a foundation, and accordingly, the energy storage battery prefabricated cabin equipment foundation also has dozens to hundreds, which is large in number and accounts for a high proportion of the construction cost.

[0039] The prefabricated cabin of energy storage battery weighs about dozens of tons, is about ten meters long and several meters wide. The prefabricated cabin equipment is installed at a height of about half a meter from the ground. The height of the battery prefabricated cabin itself is not high, about three meters, and the wind load or seismic load is relatively small, and the force is still mainly vertical load. In the above-mentioned deserts, deserts, Gobi and other areas, the geological conditions are relatively good, including some hard plastic clay foundations, the foundation bearing capacity is relatively high, and the use of natural foundations basically meets the requirements. The foundation of the conventional prefabricated cabin equipment is supported by a full-length reinforced concrete vertical wall, and a full-length reinforced concrete strip foundation is set under the full-length reinforced concrete vertical wall. Or a low reinforced concrete frame structure is used, and the weight of the prefabricated cabin equipment is supported on the reinforced concrete frame beam, and then transmitted to the reinforced concrete independent foundation through the reinforced concrete frame column. The foundation of the above-mentioned type of energy storage cabin equipment generally adopts large mechanical excavation, and the amount of earth excavation and backfilling are large. If the construction is not timely, when it encounters the rainy season, rainwater will accumulate in the foundation pit, causing disturbance to the foundation soil, construction difficulties, and affecting the construction period. This type of equipment foundation involves a lot of work such as supporting formwork, binding reinforcement and pouring concrete, most of which are basically completed manually, and the construction progress is slow. The construction site has a large amount of wet work, the level of civilized construction on site is not high, and the impact on the environment is relatively large.

[0040] If winter construction is required due to progress reasons, the above-mentioned foundation type reinforced concrete cast-in-place workload is large. When the temperature is below a certain level, a large number of winter construction measures are required, and the construction cost is high. In addition, the workload of excavation, backfilling, reinforcement and formwork is large, which is not convenient for construction in winter, and the construction progress is slow and the construction difficulty is high.

[0041] It can be seen that the use of the above-mentioned type of energy storage battery prefabricated cabin equipment foundation requires not only a large amount of excavation and backfill, but also a large amount of reinforced concrete materials. Due to the large number of energy storage battery prefabricated cabin equipment foundations, a large amount of reinforced concrete materials and labor costs will be consumed, the construction is difficult and slow, and the project cost is high.

[0042] In view of the above-mentioned technical problems, the first aspect of the present invention proposes a pile-column cast-in-place reinforced concrete prefabricated single cabin foundation for energy storage batteries. In some embodiments of the present invention, Figure 1-6 As shown, the prefabricated manifest tank foundation includes:

[0043] A reinforced concrete foundation, comprising a pile column 1 and a connecting beam integrally formed by pouring concrete 4; the pile column 1 is arranged in the foundation along a preset direction, the preset direction is parallel to the connection surface between the pile column 1 and the connecting beam; the connecting beam connects two pile columns 1 along at least one connection direction; the pile column 1 and the connecting beam both include a steel cage for supporting concrete 4.

[0044] A plurality of embedded parts 9 are inserted into the steel cage of the pile column 1 and / or the connecting beam; the embedded parts 9 include anchor bars 12 and anchor plates 11, at least a portion of the anchor plates 11 and the anchor bars 12 are embedded in the concrete 4; along a preset direction, the anchor plates 11 have a height not lower than the pile column 1 and the connecting beam.

[0045] The connector 10 is separately arranged from the embedded part 9; the connector 10 has at least one welding band 1003, which is welded and fixed to the welding surface 1101 along a preset direction; the connector 10 also has an assembly end face separated from the welding band 1003, and the assembly end face can fix the energy storage battery.

[0046] The present invention provides a pile-column-type cast-in-place reinforced concrete energy storage battery prefabricated cabin single cabin foundation. The reinforced concrete foundation consists of a pile column 1 and a connecting beam formed by pouring concrete 4. The pile column 1 and the connecting beam are arranged in the foundation in a preset direction parallel to the connecting surface. The connecting beam connects the two pile columns 1 together along at least one connecting direction. The pile column 1 and the connecting beam both include a steel cage for supporting the concrete 4. The arrangement of the pile column 1 can disperse and transfer the load of the superstructure (such as the energy storage battery) to the depth of the foundation, thereby increasing the bearing capacity of the foundation. The connecting beam provides support and rigidity, so that the entire foundation structure can better resist lateral and torsional forces. The presence of the steel cage provides strong bending and compression resistance, increasing the strength and stability of the concrete 4.

[0047] The embedded parts 9 provide a strong connection between the structural components by fixing the steel cage in the concrete 4. This is very important for ensuring the integrity and stability of the pile 1, the connecting beam and other adjacent structures; the anchor bars 12 in the embedded parts 9 extend into the concrete 4, increasing the tensile strength of the structural components. This helps to prevent the generation of tension in bending or cantilever conditions, ensuring the stability and safety of the structure; the presence of the embedded parts 9 can effectively transfer the load to the foundation soil. In particular, when there is a vertical load acting on the pile 1, the height of the anchor plate 11 can provide sufficient support and bear the pressure and shear force generated.

[0048] By using the embedded parts 9, a strong connection is formed between the pile column 1 and the connecting beam, which enhances the stability and rigidity of the entire foundation structure, thereby improving the earthquake resistance of the building and the reliability of the overall structure; because the anchor plate 11 and the anchor bar 12 are embedded in the concrete 4, the embedded parts 9 can provide additional tensile resistance to maintain the integrity and safety of the structure in the face of wind loads, horizontal earthquakes or other situations that cause tension; by setting the embedded parts 9 in the concrete 4, the reinforced concrete 4 structure in the local area can be strengthened to withstand greater stress and load. This helps to prevent local damage and cracking; the embedded parts 9 can be pre-installed before allowing the concrete 4 to be poured, reducing the working time required to install them on site. This process can speed up the progress of the construction project and improve construction efficiency.

[0049] The connector 10 is fixed to the embedded part 9 by the welding strip 1003, so as to realize the reliable connection between the embedded part 9 and other components (such as energy storage batteries). It provides a firm connection point to ensure the stability and continuity between the components; the welding strip 1003 plays an important role in the connector 10, and provides additional strength and rigidity by welding and fixing with the welding surface 1101. This helps to increase the endurance and stability of the overall connection structure.

[0050] The connector 10 can enhance the overall stability of the embedded part 9 and other components by providing a fusion connection. The use of the welding strip 1003 ensures the strength and durability of the connection point and reduces the risk of possible displacement and structural loosening. By properly welding and fixing the connector 10 and the embedded part 9, a stable connection bridge is formed, which effectively transfers the load and can withstand the pressure caused by load or vibration. This helps to increase the safety and integrity of the connection. The connector 10 has an assembly end surface fixed to components such as energy storage batteries. Such a design makes the connection process more flexible and convenient, and provides convenience for mechanical installation operations.

[0051] The use of piles and columns 1, through mechanical drilling, no excavation and backfilling on site, saving construction time, speeding up construction progress, and reducing project costs; the use of piles and columns 1 in one, the force transmission path is clearer and simpler, the connection structure is simple, and the construction is convenient; the piles in the site soil do not need to be supported by formwork, and the reinforcement of the piles and columns 1 can be completed in the reinforcement processing plant. The use of piles and columns 1 in one to cast reinforced concrete 4 energy storage prefabricated cabin equipment foundation, formwork binding reinforcement casting concrete 4 and other on-site workloads are reduced, and these links are basically completed manually, thus saving a lot of labor costs; this foundation type reduces the amount of steel bars and concrete 4 materials, reducing the project cost. There are fewer wet operations on the construction site, the degree of civilized construction on site is high, and the impact on the environment is small; the connectors are welded to the embedded steel parts, the connection is simple, and the construction is convenient.

[0052] Specifically, the pile column 1 is a cast-in-place reinforced concrete pile column, and the steel cage of the pile column 1 is formed by bundling the longitudinal steel bars 2 of the pile body and the transverse stirrups 3 of the pile body.

[0053] Specifically, the connecting beam includes a cast-in-place reinforced concrete beam 7 and a cast-in-place reinforced concrete beam 8; the cast-in-place reinforced concrete beam 7 and the cast-in-place reinforced concrete beam 8 have the same structural composition, and the steel cages of the cast-in-place reinforced concrete beam 7 and the cast-in-place reinforced concrete beam 8 are both formed by bundling the beam longitudinal steel bars 5 and the beam transverse steel bars 6.

[0054] Specifically, the embedded parts and the connecting parts are all made of steel.

[0055] As can be seen from the above, the purpose of the present invention is to provide a pile-column cast-in-place reinforced concrete energy storage battery prefabricated cabin single cabin foundation, so as to reduce the amount of excavation and backfilling, speed up the construction progress, reduce resource consumption, reduce the amount of engineering and construction cost, and use construction machinery to drill holes or rotary drilling methods at the designed position of the site, without large excavation and basically without backfilling. In the steel bar processing plant, the longitudinal steel bars of the pile body and the transverse stirrups of the pile body are tied to form a steel cage, which is transported to the site and placed in the holes that have been drilled in the site soil. The part above the site soil is supported by formwork, and the longitudinal steel bars of the beams and the transverse stirrups of the beams are tied to form the skeleton of the reinforced concrete cross beams and the reinforced concrete longitudinal beams, and the longitudinal steel bars of the reinforced concrete cross beams and the reinforced concrete longitudinal beams are bent and anchored into the reinforced concrete piles. The conventional solution directly buries the full-length channel steel on the top surface of the reinforced concrete beam. The channel steel limbs collide with the steel bars in the reinforced concrete beam, and need to be cut and processed, which is very inconvenient for construction. In order to facilitate the burial of embedded parts, the embedded parts are designed to be buried in blocks. In the steel structure processing site, the steel anchor bars are welded to the steel anchor plate to make steel embedded parts. Then the embedded steel parts are transported to the site and installed at the designed position on the top of the reinforced concrete beams and reinforced concrete longitudinal beams, and the flatness of the top surface is adjusted to meet the installation requirements. Next, pour the concrete, which is very convenient to make reinforced concrete piles and reinforced concrete beams and longitudinal beams. The reinforced concrete beams and reinforced concrete piles are erected together to form a pile-column cast-in-place reinforced concrete foundation. The reinforced concrete piles directly transmit the force to the foundation soil, the force transmission path is clear and simple, and the beam-column connection structure is simple. Then weld the connector to the embedded steel parts, and install the energy storage battery prefabricated cabin single cabin equipment on the connector.

[0056] The present invention has simple connection nodes, convenient construction, and fast construction speed. The reinforced concrete piles and columns directly transmit force to the foundation soil, the force transmission path is clear and simple, and the beam-column connection structure is simple. Construction machinery uses drilling or rotary drilling to form holes at the designed location on the site. The drilling workload is not large, and there is no large excavation and backfilling volume. Compared with conventional practices, the use of piles and columns as an integral cast-in-place reinforced concrete foundation saves steel bars and reinforced concrete, saving resources. Because the workload of supporting formwork, tying reinforcement and pouring concrete is reduced, labor costs are saved and labor productivity is improved. In large base projects, due to the large number of energy storage cabin equipment, ranging from dozens to hundreds, the amount of engineering saved is considerable and the project cost is significantly reduced.

[0057] It can be seen that for energy storage battery prefabricated cabin single cabin equipment, the use of this pile-column cast-in-place reinforced concrete energy storage battery prefabricated cabin single cabin foundation can reduce the amount of excavation and backfilling, speed up the construction progress, reduce resource consumption, reduce the amount of engineering and construction costs, and thus achieve the purpose of energy conservation and emission reduction, with very good economic and social benefits.

[0058] In any of the above embodiments, a plurality of pouring holes are drilled on the foundation along a preset direction; and a prefabricated formwork is assembled on the pouring holes to form a pouring cavity for pouring concrete 4 .

[0059] Inside the casting cavity, the steel cage of the connecting beam is knotted and fixed with the steel cage of the pile column 1 ; the anchor bars 12 are inserted into the steel cage of the connecting beam and / or the steel cage of the pile column 1 .

[0060] In this embodiment, a cavity for pouring concrete 4 can be formed by setting a pouring hole in a preset direction on the foundation and using a prefabricated formwork. This provides a suitable space and container for pouring concrete 4; by knotting and fixing the steel cage of the connecting beam and the steel cage of the pile column 1 together, a firm connection between the two is achieved. This helps to maintain the overall connectivity and stability of the structure; by inserting anchor bars 12 on the steel cage of the connecting beam and / or the pile column 1, the connection and integration of the connecting beam and the pile column 1 during the pouring process are strengthened.

[0061] As can be seen from the above, by establishing connections between the steel bars and knotting and fixing the steel cages together, the stability and strength of the connection part can be further increased. It helps to improve the stability and load-bearing capacity of the overall structure; the use of prefabricated formwork can reduce the waste of concrete 4 and ensure that the concrete 4 is constructed in the required shape and size during the pouring process. It not only saves material costs, but also improves the efficiency and quality of construction; through prefabricated formwork and steel bar knotting and fixing technology, accurate control of the concrete 4 pouring part and more convenient construction operations are achieved. It helps to improve the ease of use and consistency of the construction process; by optimizing the design and correctly placing the anchor bars 12, the durability of the connection part is improved, thereby reducing the problems that may be caused by overlap, cracking and displacement.

[0062] In any of the above embodiments, the connecting member 10 includes:

[0063] The top plate 1001 , the assembly end surface is located on the upper surface of the top plate 1001 .

[0064] Two vertical plates 1002 are provided and both are connected to the top plate 1001 ; the welding strip 1003 is located on the lower surface of the vertical plates 1002 .

[0065] In this embodiment, the connection piece 10 provides vertical support and connection functions by combining the vertical plate 1002 with the top plate 1001. Different components or structures can be connected to ensure stability and integration between each other; the combination of the vertical plate 1002 and the top plate 1001 forms a frame structure that can be used to carry and fix other components, accessories or iron parts. The arrangement of the welding strip 1003 below the vertical plate 1002 also increases the strength and rigidity of the connection piece 10.

[0066] As can be seen from the above, the combination of the vertical plate 1002 and the top plate 1001 enhances the strength of the connector 10, allowing it to withstand greater loads and vibrations. By properly installing the welding strip 1003, the stability and durability of the connector 10 can be ensured; since the connector 10 already has a frame form and comes with an assembly end surface, it is easier to install other components or accessories on the assembly end surface, simplifying the assembly process and saving time and labor costs; the structure and design of the connector 10 ensure its wide adaptability and can be combined with components or structures of different shapes, sizes and materials. This makes it highly flexible and adaptable in various scenarios and engineering projects.

[0067] Specifically, the top plate 1001 is a steel top plate made of steel, and the vertical plate 1002 is a steel vertical plate made of steel.

[0068] In any of the above embodiments, when the welding belt 1003 is welded and fixed to the welding surface 1101 , the two vertical plates 1002 , the top plate 1001 and the welding surface 1101 together form a buffer cavity 1004 .

[0069] Along the welding direction of the welding strip 1003 , a set of hanging openings 1005 are formed between the two vertical plates 1002 and the top plate 1001 .

[0070] In this embodiment, a space with a buffer cavity 1004 is formed inside the connector 10 by fixing the welding strip 1003 to the welding surface 1101, which can provide shock absorption, buffering and load dispersion functions in some cases. It can effectively reduce the impact and shock caused by external effects and reduce the stress concentration of the structure; the hanging hole 1005 formed between the vertical plate 1002 and the top plate 1001 is very useful and convenient for hanging accessories or other structural elements, providing a position for fixing, supporting and connecting parts, making the installation process more simplified and faster.

[0071] As can be seen from the above, the existence of the buffer cavity 1004 can reduce the effect of the impact caused by load or vibration transmitted to the connector 10 and its related structures, and can reduce the risk of adverse effects on the structure, thereby extending the life of the connector 10 and related structures; the setting of the hanging port 1005 makes the connector 10 more flexible and multifunctional, which can adapt to the hanging requirements of different components or accessories, and facilitate the replacement, adjustment and addition of parts to the overall device; the hanging port 1005 in the connector 10 can make the overall device, after being separated from the foundation, be lifted by external equipment, so as to be reused or replaced in different places without re-production and assembly. By temporarily hanging the accessories on the hanging port 1005, it can be positioned and adjusted more easily, thereby improving the convenience of the overall assembly process.

[0072] In summary, the buffer cavity 1004 and the hanging hole 1005 in the connector 10 play an important role. The buffer cavity 1004 reduces the influence of load transfer and structural stress, and improves the stability and life of the structure. The hanging hole 1005 provides a convenient location for hanging accessories and other components, and increases the flexibility and assembly convenience of the connector 10.

[0073] In any of the above embodiments, a circular arc surface 1006 is provided on the surface of the vertical plate 1002 around the welding belt 1003; the circular arc surfaces 1006 of the two vertical plates 1002 are arranged opposite to each other; a buffer gap 1007 is formed between the circular arc surface 1006 and the welding surface 1101;

[0074] There is a guide angle between the vertical plate 1002 and the top plate 1001, and the value range of the guide angle is 91-98.

[0075] Among them, the two vertical plates 1002 are symmetrically arranged along a preset direction.

[0076] In this embodiment, due to the buffer gap 1007 between the arc surface 1006 and the welding surface 1101, when the connector 10 is subjected to load, a certain degree of freedom and shock absorption effect can be provided. In this way, the impact and vibration of the structure can be reduced, thereby protecting the connector 10 and related structures from adverse effects; the guide angle between the vertical plate 1002 and the top plate 1001 provides force guidance, so that the overall posture can stand upright when deformed by force, avoiding deviation to the outside, ensuring that the connector 10 is longitudinally aligned with other structures, and helping to guide the assembly, adjustment and positioning of the connector 10 and other components.

[0077] As can be seen from the above, by providing the buffer gap 1007 and the arc surface 1006, the connector 10 can effectively reduce the impact and stress transfer caused by external loading. This can protect the connector 10 and its adjacent structures from damage and extend its life and reliability; the symmetrically arranged vertical plates 1002 and the design between the vertical plates 1002 and the top plate 1001 with a guide angle can ensure that the connector 10 remains intact and consistent during the installation process, which not only provides structural stability, but also ensures the correctness and accuracy of assembly;

[0078] In summary, the arc surface 1006, buffer gap 1007 and guide angle in the connector 10 all play an important role in alleviating stress and impact, maintaining structural integrity, and providing convenience, consistency and precision during assembly. Its auxiliary functions increase the reliability and efficiency of the connector 10, while providing a better construction experience and results.

[0079] Here, after the connector 10 is welded and fixed to the embedded part 9, and the connector 10 is welded and fixed to the energy storage battery, the excessive weight of the energy storage battery itself will suppress the connector 10 to deform. At this time, the guide angle between the vertical plate 1002 and the top plate 1001 causes the top plate 1001 to move downward, and drives the two vertical plates 1002 to deform in opposite directions, so that the connector 10 becomes a trapezoidal structure. The buffer cavity 1004 reserved in the middle is used to adapt to the deformation of the process. When the two vertical plates 1002 deform in opposite directions, the arc surface 1006 and the buffer gap 1007 are used to prevent the deformation process from pulling the welding belt 1003 at the bottom of the vertical plate 1002.

[0080] In any of the above embodiments, the buffer gap 1007 is communicated with the buffer cavity 1004 .

[0081] In this embodiment, when the connector 10 is subjected to external loads, shocks or vibrations, these forces can be slowed down and pass through the buffer gap 1007 into the buffer cavity 1004, that is, the connected space. This process allows the load to produce a certain degree of shock absorption and buffering, thereby protecting the structure and the connection point from damage; the buffer cavity 1004 forms a filling space around the connector 10, which can absorb a certain amount of energy and better dampen shocks and vibrations. This helps to control the stress and pressure on the material and reduce the deformation and vibration amplitude of the structure.

[0082] As can be seen from the above, by dispersing the external load or impact into the buffer gap 1007 and the buffer cavity 1004, other structures of the connector 10 will be subjected to less stress and load, reducing the pressure on the connector 10 and the surrounding structures, and improving durability and life; the buffer space allows the load, impact or vibration to be transmitted at an appropriate speed and method, and minimizes the damage to the structure, protects the integrity of the entire system, improves safety and reduces possible accident risks; the buffer cavity 1004 can effectively eliminate the interference of noise, vibration and impact, and improve the physical properties of the structure. At the same time, it also reduces the sound transmission and resonance effects, and improves the reliability and work efficiency of the structure.

[0083] In any of the above embodiments, the number of the connecting members 10 is equal to the number of the embedded members 9; the number of each group of hanging openings 1005 is two, and the two hanging openings 1005 are separately arranged;

[0084] Two hanging openings 1005 in the same group are connected to a buffer cavity 1004 , and the two hanging openings 1005 and the buffer cavity 1004 together form a heat dissipation channel.

[0085] In this embodiment, the hanging mouth 1005 and the setting connected to the buffer cavity 1004 can provide a buffering and shock-absorbing effect, help disperse and reduce the impact of external loads or impacts on the connector 10 and the structure, thereby protecting against the risk of damage and breakage; by forming a heat dissipation channel, the hanging mouth 1005, the buffer cavity 1004 and other related structures can better diffuse and conduct the heat generated at the connector 10, play an important role in preventing overheating and reducing the temperature, and help maintain the stability and normal working state of the connector 10 and the surrounding environment.

[0086] As can be seen from the above, the hanging port 1005 and the buffer cavity 1004 allow for effective energy transfer and load dispersion, improving the overall durability and reliability of the connector 10; by establishing a heat dissipation channel, the connector 10 can effectively dissipate the generated heat, prevent overheating and damage, reduce heat transfer to the concrete 4 below, and avoid damage to the interior of the concrete 4 caused by long-term use. This is particularly important for energy storage batteries with heat sources or that need to dissipate heat; by setting the hanging ports 1005 to two and separated from each other, the connector 10 is more convenient during installation and adjustment.

[0087] In any of the above embodiments, the heat dissipation channel has a flow direction; on the pile column 1 and the connecting beam, the flow directions of the heat dissipation channel are the same or different.

[0088] In this embodiment, the heat dissipation channel is a path or structure used to adjust and control the temperature of the device. It can transfer heat from the device or system by conduction, convection and radiation to maintain its normal operating temperature range; the flow direction of the heat dissipation channel refers to the direction in which heat is transferred in the channel. On the pile 1 and the connecting beam, the flow directions of the heat dissipation channels can be selected to be the same or different, depending on the specific design and requirements.

[0089] In any of the above embodiments, the direction of the flow is set according to the center of gravity position of the energy storage battery and the heat dissipation direction of the energy storage battery.

[0090] Regarding the influence of the orientation of the flow direction, the weight of the center of gravity position is higher than that of the airflow direction.

[0091] In this embodiment, setting the direction of the circulation direction by the center of gravity position and the heat dissipation direction of the energy storage battery can have an impact on the entire system, and the center of gravity position is given a higher weight because it is directly related to the stability of the energy storage battery. When the center of gravity position is reasonably distributed, the overall stability of the energy storage battery will be improved, and it will be easier to achieve balance, reducing the risk of rollover or other accidents; the heat dissipation direction of the energy storage battery also needs to be considered. By combining the heat dissipation direction with the circulation direction, the cooling effect of the battery can be improved, and dangerous situations such as shortened battery life or even fire caused by overheating can be prevented. Ensuring good heat dissipation of the battery can not only extend the service life of the battery, but also help improve the performance matching and energy conversion efficiency of the entire energy storage system, and avoid excessive heat transfer affecting the life of the concrete 4 below.

[0092] From the above, it can be seen that setting the direction of the flow according to the center of gravity position can ensure that the energy storage battery is installed in the best position, thereby improving the stability of the device; determining the direction of the flow according to the heat dissipation direction can improve the cooling effect of the storage system, reduce the risk of battery overheating, reduce energy loss, extend battery life, and improve the performance of the energy storage system; by reasonably setting the center of gravity position and heat dissipation direction of the energy storage battery to set the flow direction, the potential safety hazards caused by battery overheating and other problems are reduced, and the safety of the entire energy storage system is improved.

[0094] The embodiment of the second aspect of the present invention provides a construction method. In some embodiments of the present invention, such as Figure 7 As shown, the construction method includes:

[0095] S101 , according to the number of piles 1 required for the energy storage battery, drilling casting holes on the foundation in the same number as the piles 1 .

[0096] S102, placing the pile column 1 and the steel cage of the connecting beam according to the position of the casting hole, and assembling the formwork on the steel cage to form a casting cavity.

[0097] S103, inserting the anchor bars 12 of the embedded parts 9 on the steel cage, and pouring concrete 4 into the pouring cavity.

[0098] S104, after the concrete 4 solidifies, the formwork is removed, and the connecting member 10 is fixed to the embedded member 9 by welding the welding strip 1003 and the welding surface 1101.

[0099] S105, assembling and fixing the assembly end faces of all the connectors 10 to the energy storage batteries.

[0100] The construction method provided by the present invention first uses a construction machine to form a hole on the site soil by drilling or rotary drilling, and then ties the longitudinal steel bars and transverse stirrups of the pile body to form a steel cage in a steel bar processing site, which is then transported to the site and placed in the hole drilled in the site soil. Then, the part above the site ground is supported by formwork, and the longitudinal steel bars and transverse stirrups of the beams are tied to form the skeleton of the reinforced concrete crossbeams and reinforced concrete longitudinal beams. In the steel structure processing site, the steel anchor bars are welded to the steel anchor plates to make steel embedded parts. Then, the steel embedded parts are transported to the site, installed at the designed position on the top surface of the reinforced concrete crossbeams and reinforced concrete longitudinal beams, and the flatness of the top surface is adjusted to meet the installation requirements. Then, concrete is poured into the hole and the template, so that the reinforced concrete piles and reinforced concrete crossbeams and longitudinal beams are quickly manufactured, forming a pile-column cast-in-place reinforced concrete energy storage battery prefabricated cabin single cabin foundation. Then, the connector is welded to the embedded part, and the energy storage battery prefabricated cabin single cabin equipment is installed on the connector.

[0101] The main function of the pile column 1 and the connecting beam is to provide a strong load-bearing support capacity to stably transfer the weight to the foundation. By drilling the same number of casting holes as the pile column 1 on the foundation, placing a steel cage and pouring concrete 4 therein, it can be ensured that the energy storage battery system is firmly installed and can withstand extreme loads and external vibrations; the energy storage battery system is usually large and heavy, so it needs to have good structural stability to prevent tilting or collapse. By setting the pile column 1 and the connecting beam, the rigidity and stability of the entire system can be increased, thereby effectively reducing the risk of catastrophic failure and providing reliable support; the correct setting of the pile column 1 and the connecting beam ensures that the energy storage battery is reliably fixed on the foundation, which directly affects the safety of the system. By firmly anchoring the embedded part 9 and fixing the connector 10 on the embedded part 9 through the welding belt 1003 and the welding surface, it can be ensured that the energy storage battery system will not loosen or break in extreme environments such as high wind speed and earthquake, and provide higher safety; the setting of the pile column 1 and the connecting beam enables the energy storage battery system to have better operational flexibility. The position and quantity of the piles 1 and the connecting beams can be adjusted according to actual needs to adapt to specific site conditions and design requirements. At the same time, this modular installation method is also convenient for subsequent maintenance and disassembly.
