Technical Field
[0002] This invention relates to the field of packaging and transportation technology for interlocking bricks, and in particular to a brick stacking structure and stacking, packaging and loading / unloading method for interlocking bricks. Background Technology
[0003] H-beam connecting bricks, as a key material in slope protection engineering, are widely used in river management, road slope reinforcement, and ecological restoration projects due to the high-strength concrete properties. Compared with traditional brick masonry, their individual bricks are larger and heavier. This characteristic presents significant challenges to the loading and unloading process from the factory to the construction site. In the early days, loading and unloading relied entirely on manual labor, which not only required a large investment of manpower and resources but also resulted in low efficiency and a high risk of brick breakage during the process, adversely affecting project progress and cost control.
[0004] With technological advancements and the iteration of machinery and equipment, the loading and unloading methods for I-beam connecting bricks have been gradually upgraded, shifting from purely manual labor to a "packaging + machinery" model. This means that after packaging, loading and unloading are completed with the help of forklifts or cranes. This effectively reduces manpower input, lowers the brick damage rate during the packaging process, and significantly improves the efficiency of loading and unloading.
[0005] Currently, the mainstream efficient loading and unloading technology is centered on "pallet assistance": interlocking bricks are neatly packaged and stacked on pallets, and then lifted by forklifts to complete the loading and unloading operation. While this technology has significant advantages over manual and early mechanical loading and unloading, it still reveals several drawbacks in practical applications: First, because I-beam interlocking bricks are made of high-strength concrete, a single brick typically weighs 30-50 kg, requiring pallets with a load-bearing capacity exceeding 2 tons, necessitating the use of custom pallets, directly increasing costs by 40%-60%; second, the pallet recycling system is not yet perfect, requiring an additional 3-4 person-hours for on-site pallet dismantling, and the damage rate of delayed-recycling pallets is as high as 10%-30%, further increasing material costs; third, fuel consumption during delayed recycling increases the cost of each recycling trip by 15%-20%. These problems still restrict the economy and efficiency of I-beam interlocking brick loading and unloading. Therefore, how to develop a method for stacking, packaging, and loading and unloading I-beam interlocking bricks that can solve the existing technical problems has become a technical issue to be addressed. Summary of the Invention
[0006] Based on the aforementioned technical problems, this invention proposes a brick stacking structure for interlocking I-beam bricks and a method for stacking, packaging, and loading / unloading them, in order to solve the problems existing in the background technology.
[0007] In view of this, the present invention proposes a brick stack structure and a method for stacking, packing and unloading I-beam interlocking bricks, which includes: a brick stack body formed by I-beam interlocking bricks, wherein the first layer of I-beam interlocking bricks is arranged in 3 columns in the length direction and 9 rows in the height direction, and the second layer of I-beam interlocking bricks is arranged on the first layer in the same manner as the first layer, and a forklift hole with a length of 240mm and a height of 100mm is formed between the first layer and the second layer; The third and fourth layers of interlocking bricks of the brick stack body are arranged in three columns in the height direction and three rows in the width direction, and staggered by a gap of 25mm in the length direction, with each row having a height of 100mm; the arrangement of the fifth, sixth, seventh, and eighth layers of interlocking bricks is the same as that of the third and fourth layers of interlocking bricks.
[0008] Furthermore, the outer layer of the brick stack is provided with packing straps, and the packing structure of the packing straps does not affect the forklift opening.
[0009] Furthermore, the packing strap has a width of 20mm and a thickness of 0.8mm.
[0010] Furthermore, the packing straps are arranged in three horizontal and six vertical directions, with two horizontal packing straps tied to the middle of the first and second layers of interlocking bricks, and the third horizontal packing strap tied to the middle of the thickness of the eighth layer of interlocking bricks. The vertical packing straps are tied to both ends of the length of the interlocking bricks.
[0011] Furthermore, the dimensions of the interlocking bricks are 400mm × 300mm × 100mm (length × width × height), with two holes of 90mm × 80mm × 10mm (length × width × height) reserved in the middle; the dimensions of the brick stack body are 1200mm × 900mm × 1200mm (length × width × height).
[0012] Furthermore, the packing tape is an eco-degradable packing tape.
[0013] Furthermore, the third, fourth, fifth, sixth, seventh, and eighth layers are staggered to each other.
[0014] A method for stacking, packaging, and unloading interlocking bricks, characterized by comprising the following steps: Step 1: Stack the interlocking bricks. The first layer of interlocking bricks is stacked vertically in 3 columns along the length and in 9 rows along the height. Step 2: The second layer is stacked on top of the first layer in the same manner as in Step 1, so that a long forklift hole is formed between the two layers; Step 3: The third and fourth layers of interlocking bricks are laid horizontally in three columns along the height direction and three rows along the width direction, with a 25mm gap between them along the length direction. The height of each row is 100mm. Step 4: Stack the fifth, sixth, seventh, and eighth layers in the same manner as in Step 3; Step 5: Pack the stacked bricks together and secure them with 3 and 6 packing straps in the horizontal and vertical directions respectively. Specifically, two packing straps are placed horizontally in the middle of the first and second layers of I-beam interlocking bricks, and the third horizontal packing strap is tied in the middle of the thickness of the eighth layer of I-beam interlocking bricks. The vertical packing straps are tied at both ends of the length of the I-beam interlocking bricks. Step Six: Loading and unloading of brick stacks. Forklifts can directly insert and unload the entire stack through the forklift holes reserved between the first and second layers of interlocking bricks. When loading, the forklift legs are precisely inserted into the reserved forklift holes in the brick stack and then lifted smoothly for safe loading. After transportation to the construction site, unloading is completed in the reverse manner.
[0015] Furthermore, the stacking of bricks is carried out on an automatic packaging machine in the brick factory.
[0016] Furthermore, the forklift hole is 240mm long and 100mm high.
[0017] This invention proposes a brick stacking structure for interlocking I-beam bricks and a method for stacking, packaging, and loading / unloading them. Compared with the prior art, this invention has the following advantages: The pallet-free loading and unloading technology for interlocking bricks provided by this invention can bring many significant benefits, as follows: 1. Significantly reduced costs: The elimination of pallets completely saves on the extra costs associated with custom-made high-strength pallets, avoids material losses due to a 10%-30% breakage rate caused by delayed pallet recycling, and also saves 15%-20% on fuel costs in the pallet recycling and transportation process, achieving effective cost control from multiple dimensions.
[0018] 2. Improved space utilization and operational efficiency: Eliminates reliance on pallets, eliminates the need to reserve space for pallets, significantly reducing space occupation during transportation; and eliminates the need for pallet-related packing, stacking, and on-site disassembly operations, reducing the workload of 3-4 people per hour, making the packing and unloading process simpler, and improving overall operational efficiency.
[0019] 3. Ensure operational safety: By utilizing the forklift holes formed by the brick structure itself for handling, when lifting the brick stack, most of the weight is borne by the upper (second layer) bricks corresponding to the forklift holes, while the packing straps only bear the weight of the first layer of bricks and a small portion of the lateral pressure, effectively avoiding the breakage of the packing straps and ensuring the safety and stability of the loading and unloading process.
[0020] 4. Reduce construction waste and meet environmental protection requirements: Use biodegradable packing straps instead of traditional packing materials. After loading and unloading, the biodegradable materials can degrade naturally, which greatly reduces the waste generated during construction and is in line with the current ecological and environmental protection engineering concept.

Detailed Implementation
[0022] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the contents disclosed below.
[0024] The following combination Figures 1 to 8 The technical solution of the present invention will be further described below.
[0025] First embodiment, such as Figures 1 to 8As shown: A method for stacking, packing and unloading I-beam interlocking bricks 10, comprising: a brick stack body 11 formed by I-beam interlocking bricks 10, wherein the first layer 2 of the brick stack body 11 consists of I-beam interlocking bricks 10 arranged in 3 columns along the length direction and 9 rows along the height direction, and the second layer 3 consists of I-beam interlocking bricks 10 arranged on the first layer 2 in the same manner as the first layer 2, and a forklift hole 1 with a length of 240 mm and a height of 100 mm is formed between the first layer 2 and the second layer 3; The third layer 4 and the fourth layer 5 of the brick stack body 11 are arranged in three columns in the height direction and three rows in the width direction, and are staggered by a gap of 1425mm in the length direction. The height of each row is 100mm. The arrangement of the fifth layer 6, the sixth layer 7, the seventh layer 8, and the eighth layer 9 of the brick stack body 11 is the same as that of the third layer 4 and the fourth layer 5 of the brick stack body 10.
[0026] The outer layer of the brick stack body 11 is provided with packing straps, and the packing structure of the packing straps does not affect the forklift hole 1. The packing straps are 20mm wide and 0.8mm thick. There are 3 packing straps in the horizontal direction and 6 in the vertical direction. Two horizontal packing straps 12 are tied to the middle position of the first layer 2 and the second layer 3 interlocking bricks 10, respectively. The third horizontal packing strap 12 is tied to the middle position of the thickness of the eighth layer 9 interlocking bricks 10. The vertical packing straps 13 are tied to both ends of the length direction of the interlocking bricks 10.
[0027] The interlocking I-beam bricks 10 have dimensions of 400mm × 300mm × 100mm (length × width × height), with two pre-drilled holes in the middle measuring 90mm × 80mm × 10mm (length × width × height). The brick stack body 11 has dimensions of 1200mm × 900mm × 1200mm (length × width × height). The packing straps are eco-friendly and biodegradable. The third layer 4, the fourth layer 5, the fifth layer 6, the sixth layer 7, the seventh layer 8, and the eighth layer 9 are staggered left and right to ensure the stability of the overall structure.
[0028] A method for stacking, packaging, and unloading interlocking bricks 10, characterized by comprising the following steps: Step 1: Stack the 10 interlocking bricks. The first layer consists of 2 interlocking bricks stacked vertically in 3 columns along the length and 9 rows along the height. Step 2: The second layer 3 is stacked on top of the first layer 2 in the same manner as in Step 1, so that a long forklift hole 1 is formed between the two layers; Step 3: Place the third layer 4 and the fourth layer 5 interlocking bricks horizontally in three columns along the height direction and three rows along the width direction, with a 1425mm gap along the length direction. The height of each row is 100mm. Step 4: Stack the fifth layer (6), the sixth layer (7), the seventh layer (8), and the eighth layer (9) in the same order as in Step 3; Step 5: Pack the stacked bricks together, securing them with 3 and 6 packing straps in the horizontal and vertical directions respectively; specifically, two packing straps are placed horizontally in the middle of the first layer 2 and the second layer 3 I-beam interlocking bricks 10, and the third horizontal packing strap 12 is tied in the middle of the thickness of the eighth layer 9 I-beam interlocking bricks 10; the vertical packing strap 13 is tied at both ends of the length of the I-beam interlocking bricks 10. Step Six: Loading and unloading of brick stacks. Forklifts can directly insert and unload the entire stack via the forklift holes 1 pre-drilled between the first layer (2) and the second layer (3) of interlocking I-beam bricks (10 pieces). During loading, the forklift forks precisely insert into the pre-drilled forklift holes 1 and lift the stack smoothly for safe loading. After transporting to the construction site, unloading is completed in the reverse manner. The entire process requires no pallet assistance. The brick stacks are stacked on an automatic packaging machine at the brick factory. The forklift hole 1 is 240mm long and 100mm high.
[0029] The actual usage process is as follows: First, in the stacking stage, the interlocking bricks 10 are stacked in layers according to the specifications. By utilizing the structural characteristics of the bricks themselves, forklift holes 1 that are adapted to the forklift fork teeth are naturally formed between the first layer 2 and the second layer 3 bricks, ensuring that the stacking is neat and that the position of the forklift holes 1 is accurate and stable, laying the foundation for subsequent loading and unloading.
[0030] Next comes the packaging stage, where biodegradable strapping is used to further secure the bottom layer of the stacked bricks. The focus during packaging is on the first two bricks; proper wrapping ensures the strapping firmly restrains the bottom layer. At this stage, the strapping primarily supports the weight of the first two bricks and the lateral forces during subsequent handling; excessive wrapping of the entire stack is unnecessary.
[0031] Finally, in the loading, unloading, and transportation phase, when the transport vehicle arrives or the brick stack needs to be transferred, the forklift operator directly inserts the forklift forks into the forklift hole 1 formed between the first layer 2 and the second layer 3 of the brick stack, and slowly raises the forklift forks. At this time, most of the weight of the brick stack is borne by the bricks of the second layer 3 through the forklift hole 1, and the packing straps only assist in bearing the weight and lateral force of the first layer 2. After the forklift smoothly lifts the entire stack of bricks, the loading, unloading, and other handling operations can be completed.
[0032] Once the brick stacks are transported to the designated location on the construction site, a forklift will place them securely, and then the biodegradable packing straps will be untied. No additional pallet handling is required, as the packing straps will naturally decompose, reducing construction waste. The entire process is pallet-free, making it simple and efficient.
[0033] This invention has achieved significant results in the slope protection project of the Qingxi Reservoir Hub Project in Ninghai County by innovatively applying a pallet-free loading and unloading technology for 10-piece interlocking I-beam bricks. For the construction requirement of 1300m³ of 10-piece interlocking I-beam bricks with dimensions of 400mm×300mm×100mm, the pallet-free packaging process of this invention reduced the original loading and unloading cost of 65,900 yuan to 48,000 yuan, while controlling the brick breakage rate to 0.55%. This technology utilizes the 12km transportation distance from the brick factory to the construction site, optimizing the brick stack structure to achieve safe and efficient mechanized operation, saving the project direct costs of 17,900 yuan, fully verifying its economic efficiency and reliability in engineering projects.
[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
