Abstract
Description
Technical Field
[0001] This application relates to the field of transformer transportation technology, and more specifically, to a transportation and fixing fixture for transformer cores. Background Technology
[0002] Transformer cores, as core components of power equipment, play a crucial role in long-distance logistics transportation. With the expansion of global supply chains and the improvement of logistics efficiency, securing methods are constantly being optimized to enhance transportation safety and reliability. Current technological developments tend to simplify operating procedures and enhance adaptability, ensuring the core remains stable during transportation to meet the ever-increasing demands of power equipment.
[0003] However, existing securing methods often rely on complex and cumbersome fastening devices. In practice, these devices not only consume significant manpower and time, substantially increasing pre-transportation preparation costs, but also pose a risk of transformer core displacement due to severe vibration and impact when facing bumpy road conditions. This can lead to structural damage or functional failure, ultimately resulting in equipment scrapping. This instability severely impacts overall transportation efficiency and poses substantial safety hazards and economic losses.
[0004] There is currently no effective technical solution to the above problems. Utility Model Content
[0005] The purpose of this application is to provide a transportation and fixing fixture for transformer cores, so as to solve the problems of cumbersome and time-consuming installation of existing fixing measures and the easy displacement or damage of the core under bumpy road conditions, thereby improving the safety, reliability and efficiency of transportation.
[0006] This application provides a transportation and fixing fixture for transformer cores, used to fix transformer cores for logistics transportation, including a base plate, diagonal bracing assembly and clamping feet;
[0007] The transformer core is placed vertically on the base plate, and at least one pair of diagonal sides of the bottom of the transformer core are provided with clamping feet to define the placement position of the transformer core and fix it to the base plate.
[0008] There are two diagonal bracing assemblies, which are respectively installed on both sides of the transformer core. Each diagonal bracing assembly includes a fixing clamp and a diagonal bracing member.
[0009] The fixing clamp is fixed to the side of the transformer core. The length of the diagonal brace is adjustable and it is inclined. The top of the diagonal brace is fixed to the fixing clamp. The bottom of the diagonal brace is located outside the base plate. The height of the bottom of the diagonal brace is lower than the height of the bottom of the transformer core and higher than or level with the bottom surface of the base plate.
[0010] The aforementioned transport and fixing fixture for the transformer core includes a base with a rectangular cross-section, and an L-shaped bracket that fits against the outer side of the base, with a horizontally bent end fixed to the base plate at its bottom.
[0011] The aforementioned transport and fixing fixture for the transformer core includes a clamping member having a reinforcing rib connecting the outer side and the top surface of the horizontally bent end.
[0012] The aforementioned transport and fixing fixture for transformer cores includes a first diagonal brace and a second diagonal brace. The top end of the first diagonal brace is fixedly connected to the fixing clamp, and the bottom end is slidably installed inside the second diagonal brace and fixed to the second diagonal brace by fasteners.
[0013] The transport and fixing fixture for the transformer core has a rounded corner on the side of the bottom end of the second diagonal brace near the transformer core.
[0014] The aforementioned transport and fixing fixture for transformer cores includes a fixing clamp comprising a horizontally arranged fixing beam and a limiting buckle fixed to the bottom side of the fixing beam, wherein the top end of the diagonal brace is adjustablely fixed to the limiting buckle.
[0015] The aforementioned transport and fixing fixture for transformer cores includes multiple limiting buckles fixedly connected to the same fixing beam.
[0016] The aforementioned transport and fixing fixture for transformer cores includes a fixing beam that is a U-shaped channel steel with its slot facing upwards, and a limiting buckle that is a U-shaped channel steel with its slot facing downwards. The length direction of the slot of the fixing beam is perpendicular to the length direction of the slot of the limiting buckle.
[0017] The aforementioned transport and fixing fixture for the transformer core, wherein the fixing clamp is installed at a height higher than 1 / 2 the height of the transformer core.
[0018] The aforementioned transport and fixing fixture for the transformer core, wherein the angle between the extension direction of the diagonal brace and the horizontal plane is 45-60°.
[0019] As can be seen from the above, the transformer core transportation fixing fixture provided in this application introduces an adjustable-length and inclined brace, and cleverly designs its bottom end to be located on the outside of the base plate and directly or nearly directly abutting the bearing surface of the transport vehicle. In this way, the lateral force and overturning moment borne by the transformer core during transportation are directly transmitted to the transport vehicle. This effectively solves the problems of cumbersome and time-consuming installation of existing fixing measures and the easy displacement or damage of the core under bumpy road conditions, and achieves the effect of improving transportation safety, reliability and efficiency.

[0030] Please refer to Figures 1-4 Some embodiments of this application provide a transportation and fixing fixture for a transformer core, used to fix the transformer core 4 for logistics transportation, including a base plate 1, a diagonal brace assembly 2 and a clamping foot 3;
[0031] The transformer core 4 is placed vertically on the base plate 1. At least one pair of diagonal sides of the bottom of the transformer core 4 are provided with clamping feet 3 for defining the placement position of the transformer core 4 and fixing it to the base plate 1.
[0032] There are two diagonal bracing assemblies 2, which are installed on both sides of the transformer core 4 respectively. The diagonal bracing assembly 2 includes a fixing clamp 21 and a diagonal bracing member 22.
[0033] The fixing clamp 21 is fixed to the side of the transformer core 4. The length of the diagonal brace 22 is adjustable and it is set at an angle. The top of the diagonal brace 22 is fixed to the fixing clamp 21. The bottom of the diagonal brace 22 is located outside the base plate 1. The height of the bottom of the diagonal brace 22 is lower than the height of the bottom of the transformer core 4 and higher than or level with the bottom surface of the base plate 1.
[0034] Specifically, the base plate 1 is the basic load-bearing structure of the tooling, which can be made of steel plate, wooden pallet, or composite material board, etc., to provide a stable placement platform and serve as the mounting base for other components. It can be placed directly or fixed to the load-bearing surface of the transport vehicle using locking devices. The diagonal brace assembly 2 is a structural unit that provides lateral support for the transformer core 4, which can be made of telescopic rod, hinged rod, or multi-segment support rod, etc., to resist lateral impacts and overturning moments during transportation. The clamping foot 3 is a positioning component that limits the placement position of the bottom of the transformer core 4, which can be made of L-shaped angle brackets, U-shaped channel steel, or customized limiting blocks, etc., to ensure the initial alignment accuracy of the transformer core 4 on the base plate 1 and prevent its horizontal slippage. It can be fixed to the base plate 1 by welding, bolting, or riveting. The symmetrical layout of the diagonal brace assembly 2 is mainly to provide balanced lateral support and effectively resist impacts from different directions. The fixing clamp 21 is an intermediate component connecting the diagonal brace 22 and the transformer core 4. The diagonal brace 22 is the component that actually provides support force. This combination is mainly to achieve effective transmission of support force and adjustment of support angle. The bottom end of the diagonal brace 22 is located outside the base plate 1, that is, the bottom end does not rest on the base plate 1, but is in direct or near direct contact with the bearing surface of the transport vehicle. This design is mainly to directly transmit the lateral force and overturning moment experienced by the transformer core 4 during transportation to the bearing surface of the transport vehicle, thereby enhancing the stability of the entire transportation system and effectively preventing core displacement or damage.
[0035] Preferably, the four corners of the bottom of the transformer core 4 are provided with locking feet 3.
[0036] Specifically, one or more pairs of locking feet 3 fixed on the base plate 1 precisely define the placement position of the bottom of the transformer core 4, preventing initial sliding or displacement in the horizontal direction and providing a stable foundation for subsequent fixing. Next, two diagonal bracing assemblies 2 are installed on both sides of the transformer core 4. The fixing clamps 21 in each diagonal bracing assembly 2 are firmly fixed to the side of the transformer core 4, serving as a point for transmitting support force. The top of the diagonal bracing member 22 is connected to the fixing clamp 21, and its length can be adjusted according to the size of the transformer core 4, extending downwards at an inclined angle. Crucially, the bottom end of the diagonal bracing member 22 is designed to be located outside the base plate 1, and its height is precisely controlled so that it is lower than the bottom end of the transformer core 4, but higher than or flush with the bottom surface of the base plate 1. This unique height and positional relationship allows the bottom end of the diagonal bracing member 22 to contact the load-bearing surface of the transport vehicle directly or very close. When the transport vehicle travels on bumpy roads, the lateral impact force or overturning moment experienced by the transformer core 4 is transmitted to the diagonal brace 22 through the fixing clamp 21. Since the bottom end of the diagonal brace 22 directly abuts against the load-bearing surface of the transport vehicle, these forces can be directly distributed and transmitted to the vehicle's structure, rather than being entirely borne by the base plate 1 and the tooling itself. This direct force transmission path greatly enhances the stability of the entire transport system, effectively suppressing the displacement, swaying, or tipping of the transformer core 4 during transport, thereby ensuring the safety and reliability of the transport. Simultaneously, the adjustable length of the diagonal brace 22 simplifies the installation process and improves the versatility of the tooling.
[0037] The transformer core transportation fixing fixture of this application introduces an adjustable-length and inclined brace 22, and cleverly designs its bottom end to be located outside the base plate 1 and directly or nearly directly abutting the bearing surface of the transport vehicle. This directly transmits the lateral force and overturning moment borne by the transformer core 4 during transportation to the transport vehicle, effectively solving the problems of cumbersome and time-consuming installation of existing fixing measures and the easy displacement or damage of the core under bumpy road conditions. This achieves the effect of improving transportation safety, reliability and efficiency.
[0038] In some preferred embodiments, the transformer core 4 has a rectangular base 41, and the clamping member 3 is an L-shaped corner bracket that fits against the outside of the base 41, with a horizontally bent end 31 fixed to the base plate 1 at its bottom.
[0039] Specifically, the L-shaped corner bracket is a structural component with two mutually perpendicular planar parts, which can be formed by bending a metal sheet in one piece or by welding two sheets together.
[0040] Specifically, the clamping member 3 is designed as an L-shaped bracket, whose two mutually perpendicular contact surfaces can fit tightly against the outer side of the rectangular base 41. This fitting method limits the base 41 of the transformer core 4 in two orthogonal directions, suppressing the displacement and swaying of the core in the horizontal direction. The bottom of the L-shaped bracket has a horizontal bent end 31, which provides a wide mounting surface, allowing it to be fixed to the base plate 1. By fixing the clamping member 3 to the base plate 1, the clamping member 3 can provide continuous support and limiting effect for the transformer core 4, maintaining its position even under external impact or vibration. In addition, combined with the tooling of the base plate 1 and the diagonal brace assembly 2, the diagonal brace assembly 2 provides inclined support from the side of the transformer core 4, further enhancing the stability of the core and preventing it from tipping over. The limiting effect of the clamping member 3 and the inclined support of the diagonal brace assembly 2 work together to ensure the stability and safety of the transformer core 4 during transportation, avoiding wear or damage to the core.
[0041] In some preferred embodiments, the locking member 3 has a reinforcing rib 32 that connects the outer side surface and the top surface of the horizontally bent end 31.
[0042] Specifically, during logistics and transportation, the transformer core 4 is subjected to dynamic loads from various directions. These loads are transmitted to the clamping member 3 through the transformer core 4, especially at the corner of the L-shaped bracket, where stress concentration areas are easily formed. This solution addresses this by incorporating a reinforcing rib 32 between the vertical outer surface of the clamping member 3 and the top surface of the horizontal bending end 31, forming a triangular support structure with good stability. This reinforcing rib 32 acts as an additional rigid connector, tightly connecting the two main load-bearing surfaces of the L-shaped bracket. When the transformer core 4 is subjected to lateral impact or vibration, the force acting on the clamping member 3 is no longer concentrated only at the corner of the L-shaped bracket, but is effectively dispersed and transmitted to a larger area of the clamping member 3 through the reinforcing rib 32. The introduction of the reinforcing rib 32 increases the overall cross-sectional moment of inertia and structural stiffness of the clamping member 3, enabling it to better resist bending and deformation when subjected to dynamic loads. This structural reinforcement allows the locking member 3 to continuously maintain its restraining effect on the transformer core 4, effectively preventing displacement or damage to the transformer core 4 even under bumpy road conditions or sudden impacts. By integrating the reinforcing rib 32 into the design of the locking member 3 of the L-shaped bracket, this solution improves its structural reliability and stability in complex transportation environments while maintaining the basic positioning function of the locking member 3. This combination method gives the originally vulnerable L-shaped bracket structure resistance to deformation, thereby ensuring the safe fixation of the transformer core 4 throughout the entire transportation process.
[0043] In some preferred embodiments, the diagonal brace 22 includes a first diagonal brace 221 and a second diagonal brace 222. The top end of the first diagonal brace 221 is fixedly connected to the fixing clamp 21, and the bottom end is slidably installed in the second diagonal brace 222 and is fixed on the second diagonal brace 222 by fasteners 223.
[0044] Specifically, the first diagonal brace 221 is provided with a plurality of equidistant first adjustment holes 2211, the second diagonal brace 222 is provided with a second adjustment hole 2221, and the fastener 223 is a first bolt. The first diagonal brace 221 is installed on the second diagonal brace 222 by passing the first bolt through the second adjustment hole 2221 and the first adjustment hole 2211, so that the length of the first diagonal brace 221 can be adjusted.
[0045] Specifically, the diagonal brace 22 consists of a first diagonal brace 221 and a second diagonal brace 222, forming a sleeve-type telescopic structure. The top end of the first diagonal brace 221 is fixedly connected to the fixing clamp 21, ensuring that the supporting force is effectively transmitted from the transformer core 4. The bottom end of the first diagonal brace 221 is slidably installed inside the second diagonal brace 222, allowing the overall length of the diagonal brace 22 to be flexibly adjusted according to actual needs. After the length adjustment is completed, the two rods are locked by fasteners 223 to ensure that the adjusted length can be reliably maintained, preventing unexpected length changes due to vibration or impact during transportation, thereby enhancing the stability of the fixing fixture. The first diagonal brace 221 and the second diagonal brace 222 are coaxially arranged, ensuring that the two rods maintain good alignment during telescoping and fixing, avoiding eccentric force or jamming, and ensuring smooth adjustment and overall structural stability. The diagonal brace 22 in this design is a key component of the transformer core 4 transport and fixing fixture. Its adjustable length allows the entire fixture to adapt to transformer cores 4 of different sizes and varying transport requirements. Through this precise and stable length adjustment and locking mechanism, the fixture can provide continuous and reliable support for the transformer core 4, effectively resisting vibration and impact even under complex road conditions. This ensures the fixing effect and safety of the transformer core 4 during transport, improving the practicality and reliability of the overall transport fixture.
[0046] In some preferred embodiments, the bottom end of the second diagonal brace 222 has a rounded corner 2222 on the side near the transformer core 4.
[0047] Specifically, the transport fixing fixture of this application includes a base plate 1, clamping feet 3, and a diagonal brace assembly 2. The diagonal brace assembly 2 is installed on both sides of the transformer core 4, and the length of its diagonal brace 22 is adjustable, with its bottom end abutting against the load-bearing surface of the transport vehicle. The diagonal brace 22 consists of a first diagonal brace 221 and a second diagonal brace 222. The first diagonal brace 221 is slidably installed inside the second diagonal brace 222, and its length is adjusted by fasteners 223. In this structure, the bottom end of the second diagonal brace 222 is the key part where the diagonal brace 22 contacts the load-bearing surface of the transport vehicle. To ensure stability and safety during transportation, this contact point needs to avoid damage to the load-bearing surface. By providing a rounded corner 2222 on the side of the bottom end of the second diagonal brace 222 near the transformer core 4, when the bottom end of the diagonal brace 22 contacts the load-bearing surface of the transport vehicle, the rounded corner 2222 transforms the potentially sharp contact point into an arc surface. This curved contact surface disperses the pressure transmitted from the diagonal brace 22 to the bearing surface over a larger area, effectively reducing localized stress concentration. During the transportation of the transformer core 4, even if vibration or impact occurs, the rounded corner 2222 ensures uniform stress distribution on the contact surface, preventing scratches, dents, or perforations on the bearing surface of the transport vehicle due to localized high pressure. Furthermore, the rounded corner 2222 design eliminates the risk of cuts or abrasions that operators may face during installation, adjustment, or disassembly of the fixture, improving operational safety. Therefore, this rounded corner 2222 design, combined with the adjustable-length diagonal brace 22 structure, allows the diagonal brace 22 to effectively support the transformer core 4 while ensuring safe and reliable contact with the bearing surface of the transport vehicle, thereby improving the practicality and reliability of the entire transport fixture.
[0048] In some preferred embodiments, the fixing clamp 21 includes a horizontally arranged fixing beam 211 and a limiting buckle 212 fixed to the bottom side of the fixing beam 211, and the top of the diagonal brace 22 is fixed to the limiting buckle 212 at an adjustable tilt angle.
[0049] Specifically, the fixed crossbeam 211 is a horizontal structural component that provides a connecting base for the diagonal brace 22. It can be implemented using rectangular steel pipes, I-beams, H-beams, or other profiles with sufficient strength and rigidity. The limiting buckle 212 is a structural component used to connect to the top of the diagonal brace 22 and limit its position. It can be implemented using L-shaped angle steel, C-shaped steel, or other metal profiles with a specific shape to accommodate the top of the diagonal brace 22. Adjustable tilt angle fixing means that the connection between the top of the diagonal brace 22 and the limiting buckle 212 allows the diagonal brace 22 to change its angle with the vertical or horizontal direction within a certain range. This can be achieved by providing an arc-shaped slot on the limiting buckle 212 for bolt sliding, by using a hinge structure between the limiting buckle 212 and the top of the diagonal brace 22 supplemented with an angle locking mechanism, or by providing multiple preset holes on the limiting buckle 212 for selective bolt fixing.
[0050] Specifically, the fixing clamp 21 includes a horizontally arranged fixing beam 211, which serves as a stable base for connecting the diagonal brace 22. This beam effectively fixes the clamp to the side of the transformer core 4 and distributes the force, thereby enhancing the stability and load-bearing capacity of the fixing clamp 21 itself. A limit buckle 212 is welded to the bottom side of the fixing beam 211, providing a dedicated and structurally stable connection point for the top of the diagonal brace 22. The top of the diagonal brace 22 is adjustablely fixed to the limit buckle 212 using a second bolt 213. This connection method not only ensures a stable connection between the diagonal brace 22 and the fixing clamp 21, but its adjustable tilt angle also allows the diagonal brace 22 to easily adjust its support angle according to the size, center of gravity position, or transportation environment requirements of the transformer core 4. When the transformer core 4 is placed vertically on the base plate 1 and the diagonal bracing assembly 2 is installed on both sides of the transformer core 4, the fixing clamp 21 is stably attached to the side of the transformer core 4 through its horizontally arranged fixing beam 211. The top of the diagonal bracing 22 is connected to the limiting buckle 212 on the bottom side of the fixing beam 211 by the second bolt 213, and the tilt angle can be adjusted. At the same time, the bottom end of the diagonal bracing 22 is located outside the base plate 1 and abuts against the bearing surface of the transport vehicle. By adjusting the tilt angle of the top of the diagonal bracing 22 and the length of the diagonal bracing 22 itself, the diagonal bracing 22 can be made to abut against the transformer core 4 in a suitable supporting posture and effectively transfer its supporting force to the bearing surface of the transport vehicle. This connection method with an adjustable top angle, combined with the adjustable length of the diagonal bracing 22, allows the entire diagonal bracing system to quickly and accurately adapt to the different support requirements of the transformer core 4, thereby providing stable support during transportation and preventing displacement or damage to the transformer core 4. This structural improvement makes the originally universal fixing clamp 21 more adaptable and easy to operate, thus improving the efficiency of the overall transportation fixing fixture.
[0051] In some preferred embodiments, multiple limit buckles 212 are fixedly connected to the same fixed crossbeam 211.
[0052] Specifically, by fixing multiple limiting buckles 212 to the same fixed crossbeam 211, the top of the diagonal brace 22 can be connected to different positions on the fixed crossbeam 211 according to the actual size and shape of the transformer core 4. This design allows the connection point between the diagonal brace 22 and the fixed clamp 21 to have an adjustable range in the horizontal direction. Combining the adjustable length of the diagonal brace 22 itself and the adjustable tilt angle when connected to the limiting buckle 212, the entire diagonal brace assembly 2 can flexibly adapt to transformer cores 4 of different sizes and shapes, ensuring that the diagonal brace 22 can provide support with appropriate horizontal position, length and tilt angle. This multi-point connection setting greatly enhances the versatility and adaptability of the tooling, enabling the tooling to provide stable support for transformer cores 4 of various specifications, thereby improving the stability and safety of the transportation process, and effectively reducing the production cost of customizing different fixed clamps 21 for different specifications of cores.
[0053] In some preferred embodiments, the fixing beam 211 is a U-shaped channel steel with the slot facing upward, and the limiting buckle 212 is a U-shaped channel steel with the slot facing downward. The length direction of the slot of the fixing beam 211 is perpendicular to the length direction of the slot of the limiting buckle 212.
[0054] Specifically, "perpendicular in length" means that the main axes or extension directions (i.e., the length direction) of the two U-shaped channel steels are orthogonal to each other. This arrangement can form a cross structure and enhance the overall rigidity of the connection.
[0055] Specifically, the fixed crossbeam 211 is designed as a U-shaped channel steel with the slot facing upwards. This U-shaped cross-section structure gives the fixed crossbeam 211 bending and torsional resistance, enabling it to withstand various loads from the diagonal brace 22 and during transportation, preventing deformation. The upward-facing slot also facilitates connection with other structural components. The limiting buckle 212 is designed as a U-shaped channel steel with the slot facing downwards, and its U-shaped structure also provides its own strength. The downward-facing slot allows the limiting buckle 212 to be securely welded or connected to the bottom side of the fixed crossbeam 211, providing a sturdy connection point for the top of the diagonal brace 22. This design ensures that the limiting buckle 212 is not easily deformed when bearing the force transmitted by the diagonal brace 22, and can effectively transfer the force to the fixed crossbeam 211. More importantly, the length direction of the slot of the fixed crossbeam 211 is designed to be perpendicular to the length direction of the slot of the limiting buckle 212. This vertically intersecting arrangement creates a rigid structure at the connection between the fixed beam 211 and the limiting buckle 212. When the diagonal brace 22 applies force to the fixed beam 211 through the limiting buckle 212, the force can be transmitted and dispersed along the axial directions of the two U-shaped channel steels, thus utilizing the structural advantages of the two types of U-shaped channel steels and enhancing the overall load-bearing capacity and deformation resistance of the entire fixing clamp 21. This optimized design ensures that the fixing clamp 21 maintains its structural integrity and fixing effect during the transportation of the transformer core 4, even when facing vibration and impact, thereby guaranteeing the transportation safety of the transformer core 4.
[0056] In some preferred embodiments, the mounting height of the fixing clamp 21 on the transformer core 4 is higher than 1 / 2 the height of the transformer core 4.
[0057] Specifically, by setting the mounting height of the fixing clamp 21 on the transformer core 4 to more than half the total height of the transformer core 4, the support point of the diagonal brace 22 for the transformer core 4 is raised to a higher position. As a component with a high center of gravity, the transformer core 4 is susceptible to overturning moments due to inertia during transportation. This high-position support allows the diagonal brace 22 to form a longer effective lever arm when resisting the overturning of the transformer core 4. According to the principle of torque balance, under the same supporting force, the longer the lever arm, the greater the overturning moment it can resist; conversely, to resist the same overturning moment, the required supporting force will be correspondingly reduced. Therefore, this design significantly enhances the stabilizing effect of the diagonal brace assembly 2 on the transformer core 4, enabling it to more effectively suppress the swaying and tilting of the transformer core 4 during transportation and prevent it from overturning. The base plate 1 and the clamping feet 3 provide basic positioning and anti-slip functions, while the high-positioned diagonal brace assembly 2 provides effective resistance to overturning moments. This combination utilizes the structural characteristics and center of gravity distribution of the transformer core 4 itself, which improves the stability of the entire transportation and fixing fixture, thereby solving the problem of insufficient stability caused by the support point being too low.
[0058] In some preferred embodiments, the angle (i.e., the tilt angle) between the extension direction of the diagonal brace 22 and the horizontal plane is 45-60°.
[0059] Specifically, such as Figure 1 As shown, the diagonal brace 22 is inclined outward from top to bottom in the direction away from the transformer core 4, forming an outward-opening support posture.
[0060] Specifically, the inclination angle of the diagonal brace 22 is limited to the range of 45-60°, that is, the angle between its axial direction and the horizontal direction is 45-60°, so that the diagonal brace 22 can provide both lateral and vertical support. During transportation, when the vehicle encounters bumps, sudden braking, or turning, the transformer core 4 will generate inertial force, attempting to undergo lateral displacement or tip over. At this time, the outwardly inclined diagonal brace 22 can effectively decompose these lateral forces, converting part of them into a downward vertical component force transmitted to the bearing surface, and another part into an outward horizontal component force, thereby resisting the tendency of the core to tip over. The inclination angle of 45-60° ensures the efficiency of this force decomposition, avoiding the problems of the lateral support being insufficient due to an excessively large angle, or the vertical support efficiency being reduced and space being occupied due to an excessively small angle.
