Description

Technical Field

[0001] This invention relates to the field of building materials technology, and in particular to an exterior wall lattice brick and its molding die. Background Technology

[0002] Lattice bricks are building blocks with through holes. Due to their good ventilation and beautiful appearance, they are widely used in the exterior walls of buildings in temperate climates such as South America, Africa, and South Asia. Lattice bricks can provide natural ventilation to the interior while reducing building energy consumption, playing an important role in ventilation and decoration in various buildings such as residences, factories, and schools.

[0003] As Chinese companies continue to expand their overseas engineering projects, the application of lattice bricks in tropical and rainy regions faces significant technical challenges. These regions are characterized by hot and humid climates, as well as heavy rainfall and sudden downpours, placing a dual requirement on lattice bricks: both ventilation and rain protection.

[0004] Existing lattice bricks on the domestic and international markets often prioritize ventilation and aesthetics, but in areas with high rainfall, they struggle to achieve both ventilation and rain protection. The perforated design of existing lattice bricks fails to effectively resolve the conflict between ventilation and rain protection, making it difficult to prevent rainwater from entering the building while ensuring good ventilation. This technical deficiency leads to indoor waterlogging and even water accumulation, creating a love-hate relationship with lattice bricks in construction projects and severely restricting their widespread application in tropical, rainy regions.

[0005] Therefore, there is an urgent need for a lattice brick technology solution that can effectively prevent rainwater from entering the room while ensuring good ventilation through a reasonable perforation design, and can maintain good rainproof performance, especially under heavy rain conditions with large instantaneous rainfall. Summary of the Invention

[0006] This invention provides an exterior wall lattice brick and its molding mold. The exterior wall lattice brick can effectively drain rainwater while ensuring air circulation, thus achieving a balance between ventilation and rain protection.

[0007] In a first aspect, the present invention provides an exterior wall lattice brick, comprising a brick body, the brick body having a through inclined channel, the inclined channel having a first opening facing the outside and a second opening facing the inside, the inclined channel being inclined upward from the first opening to the second opening.

[0008] In one possible implementation, the side of the brick facing the outside is provided with a first groove that communicates with the first opening. The first groove is used to guide airflow from the first opening into the inclined channel.

[0009] In one possible implementation, a first drainage surface is provided at the bottom of the inclined channel, and a second drainage surface is provided at the bottom of the first groove, with the second drainage surface connected to the output end of the first drainage surface.

[0010] In one possible implementation, the second flow-guiding surface is provided with a flow-guiding groove or a flow-guiding flange to disperse the water flow.

[0011] In one possible implementation, a third flow-guiding surface is provided at the top of the first groove, which is used to guide the airflow to the second flow-guiding surface.

[0012] In one possible implementation, a fourth drainage surface is provided at the top of the inclined channel, a first transition surface is provided at the end of the first drainage surface adjacent to the second opening, and a second transition surface is provided at the end of the fourth drainage surface adjacent to the first opening, wherein the height of the first transition surface is greater than or equal to the height of the second transition surface.

[0013] In one possible implementation, the first transition surface and the second transition surface are either a plane or an arc surface.

[0014] In one possible implementation, a second groove communicating with a second opening is provided on the side of the brick facing the interior, and the second groove is arranged 180° rotationally symmetrically with the first groove.

[0015] In one possible implementation, the tilt angle of the inclined channel relative to the horizontal plane is 30°-45°.

[0016] In one possible implementation, the inner surface of the inclined channel is coated with a hydrophobic coating.

[0017] In one possible implementation, the brickwork includes: an outer frame structure; and two partition structures disposed on the outer frame structure, with an inclined channel formed between the two partition structures.

[0018] In one possible implementation, the two separating structures are arranged in a 180° rotational symmetry configuration.

[0019] Secondly, the present invention provides a molding die for preparing the above-mentioned exterior wall lattice bricks, comprising two units, each unit comprising a half frame and an extension disposed within the half frame; When the two individual units are fastened together, the two half-frames form a mold cavity for preparing the brick body, and the two extensions abut against each other within the mold cavity to form an inclined channel for the brick body.

[0020] In one possible implementation, the two units are arranged in a 180° rotational symmetry configuration.

[0021] The exterior wall lattice bricks provided by this invention have a through-type inclined channel. This inclined channel has a first opening facing the outside and a second opening facing the inside. The inclined channel is set upwards from the first opening to the second opening, achieving a coordination of ventilation and rainproofing functions using the principle of gravity. When outdoor air enters through the first opening, driven by the temperature and pressure difference between the inside and outside, it flows upwards along the inclined channel to the second opening, forming a stable ventilation path. When rainwater enters through the first opening with the wind, it cannot reach the second opening along the upward inclined path due to gravity, but instead naturally flows back to the first opening for discharge. The upwardly inclined channel geometry produces different flow effects for gases and liquids. Gases can overcome gravity and flow along the channel with the help of driving force, while liquids are dominated by gravity and cannot flow upwards, thus achieving a differentiated effect of gas passage and liquid blockage within the same channel. In the heavy rain conditions of tropical regions such as South America and Africa, traditional lattice bricks often cause rainwater to directly enter the room, causing water accumulation. However, the inclined channel of this invention can prevent rainwater from entering while maintaining ventilation, avoiding indoor waterlogging. This invention establishes a gravity drainage mechanism through the inclined channel, achieving effective rainwater removal while ensuring air circulation. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0034] The following is combined Figures 1 to 4 The present invention describes an exterior wall lattice brick, including a brick body 1, the brick body 1 having a through inclined channel 11, the inclined channel 11 having a first opening 111 facing the outside and a second opening 112 facing the inside, the inclined channel 11 being inclined upward from the first opening 111 to the second opening 112.

[0035] In this invention, the brick body 1 is provided with a through inclined channel 11. The inclined channel 11 has a first opening 111 facing the outside and a second opening 112 facing the inside. The inclined channel 11 is inclined upward from the first opening 111 to the second opening 112, and the ventilation and rainproof functions are coordinated by utilizing the principle of gravity. When outdoor air enters through the first opening 111, it is driven by the temperature and pressure difference between the inside and outside and flows upward along the inclined channel 11 to the second opening 112, forming a stable ventilation path. When rainwater enters the first opening 111 with the wind, it cannot reach the second opening 112 along the upward inclined path due to gravity, but naturally flows back to the first opening 111 and is discharged. The upward inclined channel geometry produces different flow effects for gases and liquids. Gases can overcome gravity and flow along the channel with the help of driving force, while liquids are dominated by gravity and cannot flow upward, thus achieving a differentiated effect of gas passage and liquid obstruction within the same channel. In tropical regions like South America and Africa, where heavy rainfall is common, traditional lattice bricks often cause rainwater to directly enter indoor spaces, resulting in water accumulation. However, the inclined channel 11 of this invention prevents rainwater from entering while maintaining ventilation, thus avoiding indoor waterlogging. This invention establishes a gravity drainage mechanism through the inclined channel 11, effectively removing rainwater while ensuring air circulation.

[0036] Specifically, the upward tilt of the inclined channel 11 creates a directional fluid channel. When air flows, it enters through the lower first opening 111, passes through the inclined channel 11, and reaches the higher second opening 112, forming a stable airflow circulation by utilizing the temperature and pressure differences between indoors and outdoors. When rainwater enters, due to the upward tilt of the channel, the rainwater naturally flows back to the first opening 111 under gravity and is discharged, preventing accumulation within the channel.

[0037] In one specific embodiment, the exterior wall lattice bricks are applied to the exterior walls of buildings in rainy tropical regions such as South America and Africa. Under conditions of heavy downpours, traditional vertical perforated lattice bricks can cause rainwater to directly flow into the interior, resulting in water accumulation. However, the inclined channel 11 design of this invention can effectively prevent rainwater from entering while maintaining good ventilation, thus avoiding indoor waterlogging.

[0038] In related technologies, existing lattice bricks mostly adopt vertical through holes or horizontal through holes, emphasizing ventilation and aesthetics. However, in areas with heavy rainfall, it is difficult to achieve both ventilation and rain protection, leading to indoor waterlogging and even water accumulation, resulting in a love-hate relationship with lattice bricks in construction projects. In this embodiment of the invention, the design of the inclined channel 11 effectively solves the contradiction between ventilation and rain protection. Through the upward-sloping channel configuration, normal air circulation is ensured while rainwater is naturally drained using gravity, providing a reliable technical solution for ventilation of building exterior walls in rainy areas.

[0039] The inclined channel 11 maintains a consistent width along its extension direction, which avoids accelerating the airflow and ensures the stability of the indoor airflow.

[0040] In some embodiments, the side of the brick 1 facing the outside is provided with a first groove 12 communicating with the first opening 111. The first groove 12 is used to guide airflow from the first opening 111 into the inclined channel 11.

[0041] In this invention, a first groove 12 communicating with a first opening 111 is provided on the outdoor side of the brick 1. The first groove 12 is used to guide airflow from the first opening 111 into the inclined channel 11. Through the guiding effect of the groove structure, the orderly organization of airflow and the initial diversion of rainwater are achieved. The groove structure can collect and converge outdoor airflow from different directions, forming a relatively concentrated and stable airflow line, thereby improving ventilation efficiency.

[0042] Specifically, the first groove 12 is located on the side of the brick body 1 facing the outside, and is directly connected to the first opening 111 to form an extension of the airflow channel. When outdoor wind blows towards the exterior wall of the building, the first groove 12 plays a role in collecting and guiding the dispersed airflow and then introducing it into the first opening 111. At the same time, the setting of the first groove 12 provides a frame structure around the brick body 1, which enhances the overall structural strength of the lattice brick.

[0043] In one specific embodiment, when used at overseas engineering sites, the first groove 12 can adapt to airflow conditions with different wind directions. Whether it is a headwind or an oblique wind, the groove can effectively capture the airflow and guide it into the inclined channel 11. When heavy rain is accompanied by strong winds, the first groove 12 can also initially disperse the impacting rainwater, reducing the amount of water directly impacting the first opening 111.

[0044] In this embodiment of the invention, the first groove 12 establishes a pre-treatment mechanism for airflow. The groove not only improves airflow organization, making the air entering the inclined channel 11 more stable and orderly, but also creates conditions for rainwater diversion through structural design, thereby enhancing the overall rainproof performance.

[0045] In some embodiments, the bottom of the inclined channel 11 is provided with a first drainage surface 113, and the bottom of the first groove 12 is provided with a second drainage surface 121, the second drainage surface 121 being connected to the output end of the first drainage surface 113.

[0046] In this invention, a first drainage surface 113 is provided at the bottom of the inclined channel 11, and a second drainage surface 121 is provided at the bottom of the first groove 12. The second drainage surface 121 is connected to the output end of the first drainage surface 113. By establishing a continuous drainage surface system, organized drainage of rainwater is achieved. The first drainage surface 113 ensures that rainwater entering the inclined channel 11 can flow back smoothly, and the second drainage surface 121 guides the rainwater in the first groove 12 into the first drainage surface 113, forming a complete drainage path.

[0047] Specifically, the first drainage surface 113 is arranged along the bottom of the inclined channel 11, providing a dedicated flow channel for rainwater return. The second drainage surface 121 is located at the bottom of the first groove 12 and is connected to the output end of the first drainage surface 113, eliminating the interruption in drainage. When rainwater enters the first groove 12 or the inclined channel 11, the drainage surface system guides the rainwater to flow along a preset path to the first opening 111 for discharge.

[0048] In one specific embodiment, under heavy rain conditions, rainwater impacts the surface of the brick 1 and enters the first groove 12. The second drainage surface 121 immediately guides the rainwater to the first drainage surface 113. Even if some rainwater enters the inclined channel 11, the first drainage surface 113 can ensure that the rainwater quickly flows back to the first opening 111, avoiding water accumulation in the channel and affecting ventilation.

[0049] In some embodiments, the second flow-guiding surface 121 is provided with a flow-guiding groove or a flow-guiding flange for dispersing water flow.

[0050] In this invention, the second drainage surface 121 is provided with a guide channel or a guide flange to disperse the water flow. By changing the shape and direction of the water flow, the concentration of rainwater impact is reduced. The guide channel can disperse the concentrated water flow into multiple fine streams, and the guide flange can change the direction of the water flow. The two work together to reduce the probability of rainwater directly impacting the inclined channel 11.

[0051] Specifically, the guide channel is a groove structure on the second flow-inducing surface 121. When rainwater impacts the first groove 12, the guide channel divides the water flow into multiple smaller streams, reducing the impact force of a single stream. The guide flange is a protruding structure on the second flow-inducing surface 121, which can deflect the water flow and prevent it from impacting the first opening 111 in a straight line. Through the above settings, the water flow is sufficiently dispersed and guided before entering the first flow-inducing surface 113.

[0052] In some embodiments, a third flow-guiding surface 122 is provided on the top of the first groove 12, and the third flow-guiding surface 122 is used to guide the airflow to the second flow-guiding surface 121.

[0053] In this invention, a third airflow guiding surface 122 is provided at the top of the first groove 12. The third airflow guiding surface 122 is used to guide the airflow to the second airflow guiding surface 121. Through the optimized design of the airflow path, the ventilation efficiency is improved and the airflow organization is enhanced. The third airflow guiding surface 122 provides guidance for the airflow entering the first groove 12, enabling the airflow to smoothly transition to the area of ​​the second airflow guiding surface 121 and then enter the inclined channel 11.

[0054] Specifically, the third airflow guiding surface 122 is located at the top of the first groove 12, forming a guide surface for airflow. When outdoor air enters the first groove 12, the third airflow guiding surface 122 guides the airflow downwards to the area of ​​the second airflow guiding surface 121, preventing the airflow from generating eddies or backflow within the groove. This orderly airflow organization reduces flow resistance and improves ventilation efficiency.

[0055] In one specific embodiment, under natural ventilation conditions, the outdoor breeze is guided by the third airflow surface 122 to form a stable airflow line. The airflow smoothly transitions from the third airflow surface 122 to the second airflow surface 121, and then enters the inclined channel 11 through the first opening 111. The entire airflow path is smooth and unobstructed, avoiding the loss of ventilation efficiency caused by airflow turbulence.

[0056] In some embodiments, a fourth drainage surface 114 is provided at the top of the inclined channel 11, a first transition surface 115 is provided at one end of the first drainage surface 113 adjacent to the second opening 112, and a second transition surface 116 is provided at one end of the fourth drainage surface 114 adjacent to the first opening 111, wherein the height of the first transition surface 115 is greater than or equal to the height of the second transition surface 116.

[0057] In this invention, a fourth flow-guiding surface 114 is provided at the top of the inclined channel 11, a first transition surface 115 is provided at one end of the first flow-guiding surface 113 adjacent to the second opening 112, and a second transition surface 116 is provided at one end of the fourth flow-guiding surface 114 adjacent to the first opening 111. The height of the first transition surface 115 is greater than or equal to the height of the second transition surface 116. By establishing a complete flow-guiding surface system and a reasonable height difference configuration, the overall optimization of airflow organization and the further enhancement of rainproof performance are achieved.

[0058] Specifically, the fourth drainage surface 114 is located at the top of the inclined channel 11, providing a smooth flow surface for the airflow within the channel. The first transition surface 115 and the second transition surface 116 are located at opposite ends of the first drainage surface 113, forming a favorable flow gradient through their height difference. The configuration where the height of the first transition surface 115 is greater than or equal to the height of the second transition surface 116 ensures smooth airflow and prevents backflow of rainwater at the second opening 112. The first drainage surface 113 and the fourth drainage surface 114 are positioned opposite each other, forming a space between them for the inclined channel 11. The first drainage surface 113 and the fourth drainage surface 114 can be planar, forming an inclined straight line 11; alternatively, the first drainage surface 113 and the fourth drainage surface 114 can be curved surfaces, thus forming an inclined channel 11 with a certain curvature.

[0059] In this embodiment of the invention, the fourth airflow guide surface 114 and the transition surface system establish a flow field optimization mechanism inside the inclined channel 11. Through careful design of the airflow path and reasonable configuration of the height difference, ventilation resistance is reduced and rainproof effect is improved, achieving dual performance optimization.

[0060] In some embodiments, the first transition surface 115 and the second transition surface 116 are either a plane or an arcuate surface.

[0061] In this invention, the first transition surface 115 and the second transition surface 116 are either planar or arc-shaped surfaces. By providing different transition surface shape options, adaptability to different application requirements and manufacturing conditions is achieved. Planar transition surfaces have a simple structure and lower manufacturing costs; arc-shaped transition surfaces can further optimize the flow field and reduce flow resistance.

[0062] Specifically, planar transition surfaces use straight lines to connect different height positions, which is relatively simple to manufacture and suitable for mass production. Curved transition surfaces use curves to achieve a smooth transition, reducing airflow separation in the transition area and minimizing flow losses. The choice between these two shapes provides flexibility in product design.

[0063] Preferably, the first transition surface 115 and the second transition surface 116 are flat, which facilitates mold processing and forming.

[0064] In some embodiments, the side of the brick body 1 facing the interior is provided with a second groove 13 communicating with the second opening 112, and the second groove 13 is arranged in a 180° rotational symmetry with the first groove 12.

[0065] In this invention, a second groove 13 communicating with a second opening 112 is provided on the side of the brick 1 facing the interior. The second groove 13 and the first groove 12 are arranged 180° rotationally symmetrically. Through the symmetrical structure design, the manufacturing process is simplified and the construction and installation are facilitated. The symmetrical arrangement allows the upper and lower molds to adopt the same design, reducing the mold manufacturing cost and providing a foolproof function for construction.

[0066] Specifically, the second groove 13 is located on the side of the brick 1 facing the interior, forming a complete 180° rotational symmetry with the first groove 12. This symmetrical arrangement ensures the correct functional effect of the lattice bricks regardless of their orientation, eliminating the need for workers to distinguish between the vertical and horizontal directions of the brick 1. Furthermore, the symmetrical structure makes the upper and lower parts of the mold identical, simplifying mold design and manufacturing.

[0067] In this embodiment of the invention, the 180° rotational symmetry of the second groove 13 solves both manufacturing and construction challenges. The symmetrical structure not only reduces manufacturing costs but also improves the convenience and reliability of construction, making it particularly suitable for overseas engineering applications where equipment and materials are scarce.

[0068] In some embodiments, the tilt angle of the inclined channel 11 relative to the horizontal plane is 30°-45°.

[0069] In this invention, the inclined channel 11 has an inclination angle of 30°-45° relative to the horizontal plane. By precisely controlling the inclination angle, an optimal balance between ventilation efficiency and rainproof effect is achieved. This angle range is determined based on fluid mechanics principles and actual engineering requirements, ensuring both effective rainwater drainage and maintaining good ventilation performance.

[0070] Specifically, when the tilt angle is between 30° and 45°, rainwater can overcome surface tension and frictional resistance under the influence of gravity and flow smoothly out along the bottom of the tilted channel 11. At the same time, this angle range has a limited impact on increasing airflow resistance, maintaining high ventilation efficiency. The angle selection takes into account the rainfall characteristics of different regions and the building's ventilation requirements.

[0071] In this embodiment of the invention, the 30°-45° tilt angle achieves a harmonious balance between ventilation and rainproof performance. This angle range has been practically verified to maximize ventilation performance while ensuring rainproofing, providing reliable technical parameters for building ventilation in rainy areas.

[0072] In some embodiments, the inner surface of the inclined channel 11 is coated with a hydrophobic coating.

[0073] In this invention, the inner surface of the inclined channel 11 is coated with a hydrophobic coating. Through the application of surface treatment technology, the rainproof performance is further enhanced and the durability of the material is improved. The hydrophobic coating can reduce the probability of rainwater adhering to the inner surface of the channel, promote the rapid flow of rainwater, and prevent long-term moisture erosion from damaging the material.

[0074] Specifically, the hydrophobic coating alters the wetting properties of the inner surface of the inclined channel 11, increasing the contact angle between rainwater and the surface and reducing water adhesion and penetration. When a small amount of rainwater enters the inclined channel 11, the hydrophobic coating allows the rainwater to flow and drain more quickly, reducing the residence time of water within the channel.

[0075] In some embodiments, the brick body 1 includes: an outer frame structure 14; two partition structures 15 disposed on the outer frame structure 14, with an inclined channel 11 formed between the two partition structures 15.

[0076] In this invention, the brick body 1 includes an outer frame structure 14 and two partition structures 15 disposed on the outer frame structure 14, forming an inclined channel 11 between the two partition structures 15. Through modular structural design, standardization of product manufacturing and reliability of function are achieved. The outer frame structure 14 provides overall strength and installation foundation, while the partition structures 15 ensure the precise forming of the inclined channel 11.

[0077] Specifically, the outer frame structure 14 forms a boundary framework around the brick body 1, providing the necessary structural strength for the lattice bricks and a foundation for connection with the wall. Two partition structures 15 are located inside the outer frame structure 14, and their relative positions and shapes determine the geometry and inclination angle of the inclined channel 11. This structured design ensures that each component has a clear functional division.

[0078] In one specific embodiment, during mass production, the outer frame structure 14 and the partition structure 15 can be subjected to separate quality control to ensure that each part meets the design requirements. The assembled lattice bricks can guarantee the dimensional accuracy and angular precision of the inclined channel 11, thereby ensuring consistent ventilation and rainproof performance, suitable for the stringent requirements of engineering projects for product consistency.

[0079] In some embodiments, the two partition structures 15 are arranged in a 180° rotational symmetry configuration.

[0080] In this invention, the two separating structures 15 are arranged with 180° rotational symmetry. Through the application of symmetrical structures, manufacturing costs are minimized and production efficiency is significantly improved. The symmetrical design halves the complexity of the manufacturing mold while ensuring the accuracy of the geometry of the inclined channel 11.

[0081] Specifically, the 180° rotational symmetry of the two partition structures 15 means that one partition structure 15 can be obtained by rotating the other partition structure 15 by 180°, thus requiring only one set of molds to be designed and manufactured. During production, the same set of molds can be used to manufacture both partition structures 15, maximizing mold utilization.

[0082] The mold used to manufacture bricks consists of two mold units that fit together to form a cavity. Concrete is poured into this cavity to create the bricks. Other malleable materials can be used instead of concrete. The inclined channel can be adjusted in angle or width according to environmental characteristics, thereby adjusting the airflow direction and volume.

[0083] In this embodiment of the invention, the 180° rotational symmetry of the partition structure 15 minimizes the number of molds required. Manufacturing two partition structures 15 using a single mold not only reduces mold manufacturing and maintenance costs but also improves production flexibility, making it particularly suitable for engineering projects requiring rapid deployment and cost control.

[0084] like Figure 5-9 As shown, the present invention provides a molding die for preparing the above-mentioned exterior wall lattice bricks, comprising two units 2, each unit 2 comprising a half frame 21 and an extension 22 disposed within the half frame 21; When the two individual units 2 are fastened together, the two half-frames 21 form a mold cavity for preparing the brick body, and the two extensions 22 abut against each other in the mold cavity to form an inclined channel 11 for the brick body 1.

[0085] In this invention, the molding die consists of two individual units 2, which can be snapped together to form a complete molding die. Two semi-frames 21 form a cuboid cavity for shaping the brick 1. One end of the cavity is sealed, and the other end has an opening for pouring molding material into the cavity. The molding material can be concrete, but other plastic materials can also be used. After pouring the molding material, a sealing plate is placed at the opening to ensure the flatness of the brick 1 at the opening. Two extensions 22 abut against each other within the cavity, forming an inclined structure that penetrates the cavity, creating an inclined channel 11 within the brick 1. After the brick 1 is formed, it can be removed from the cavity by disassembling the two individual units 2. The use of a two-unit structure facilitates the separation of the extensions 22 from the brick.

[0086] Specifically, the molding die can be made of rigid ABS plastic, which is injection molded for easy mass production. Of course, other malleable materials can also be used. To improve the stability of the die structure, reinforcing ribs are provided on the outer perimeter of the die, thereby ensuring the quality and consistency of the bricks produced by the molding die.

[0087] In some embodiments, the two monomers 2 are arranged in a 180° rotational symmetry configuration.

[0088] In this invention, by setting the two monomers 2 to a 180° rotational symmetry, the shapes of the two monomers 2 are completely identical; that is, rotating one monomer 2 by 180° yields the other monomer 2. Setting the two monomers 2 to have the same shape reduces mold costs. Compared to molding molds with two different monomers 2, if one monomer 2 is damaged or lost, a corresponding monomer 2 must be found to replace it. Furthermore, during storage or transportation, the two different monomers 2 need to be stored separately, which is inconvenient for transportation and daily management. This application, by designing the two monomers to have identical shapes, effectively solves the above problems. If one monomer is damaged or lost, either monomer 2 can be found to replace it, and transportation and storage can be carried out uniformly, facilitating transportation and daily management.

[0089] Specifically, the vertical cross-section of the two extensions 22 is "flag" shaped, including a triangular part and a vertical part. When the two units 2 are fastened together, the two triangular parts abut against each other, forming an inclined strip structure in the mold cavity, which is used to form an inclined channel in the brick body.

[0090] In some embodiments, the end of the extension 22 facing away from the mold cavity is provided with a receiving groove 23, which is used to receive the extension 22 of another unit 2.

[0091] By providing a receiving groove 23 at the end of the extension 22 facing away from the mold cavity, two monomers 2 can be stacked. When stacking, the extension 22 of one monomer 2 is inserted into the receiving groove 23 of the other monomer 2, thereby ensuring the stability of the stacked arrangement of the two monomers 2 and reducing the space occupied.

[0092] Lattice bricks, due to their excellent ventilation properties, are widely used on building exteriors in temperate regions such as South America, Africa, and South Asia, providing natural ventilation while reducing building energy consumption. However, these regions also face rainy climates with high sudden rainfall, so effective rainproofing measures would greatly enhance functionality, making them widely applicable in construction projects both domestically and internationally.

[0093] In one specific embodiment, Chinese companies facing shortages of equipment and materials in overseas projects, lacking large-scale brick factories, find that rainproof exterior wall lattice bricks, due to their unique structure, require pre-processing brick molds in China, transporting them in batches to the overseas construction site, and then casting the bricks into shape. On-site brick production reduces costs, shortens construction time, and solves the problem of the general contractor lacking raw materials in this embodiment. This solution, focusing on construction and transportation convenience, develops the bricks and molds simultaneously, improving upon the shortcomings of existing molding mold technology, such as large space occupation, poor stacking stability, and inconvenience in transportation and management. The simultaneously developed molding molds in this solution are easy to transport, lightweight, and flexibly combinable, making them widely applicable to construction projects in countries with limited material manufacturing capabilities.

[0094] In this application, by providing a receiving groove 23 on the monomer 2 to accommodate the extension 22, the use of the molding die is not affected, and multiple monomers 2 can be stacked during storage and transportation. In two adjacent monomers 2, the extension 22 at the top of the lower monomer 2 is inserted into the receiving groove at the bottom of the upper monomer 2, and the two half-frames 21 can also be effectively inserted.

[0095] Specifically, the receiving groove 23 adopts a gradually expanding structure, while the extension 22 has a triangular structure, and the half-frame 21 also adopts a gradually expanding structure. This facilitates the smooth insertion of the extension 22 of one unit 2 into the receiving groove 23 of the other unit 2, forming a stable stacking effect. The half-frame 21 has a relatively thin wall thickness, and the half-frame 21 is made of injection-molded material with a certain elastic deformation. The use of a gradually expanding structure with a small angle allows for the insertion and stacking of two units 2.

[0096] Furthermore, a second support surface 231 is provided in the receiving groove 23, and a first support surface 221 is provided in the extension 22. When the extension 22 is located in the receiving groove 23, it abuts against the second support surface 231 through the first support surface 221, thereby realizing the reliable stacking of two units 2 and ensuring the stability when multiple units 2 are stacked.

[0097] This invention, focusing on the convenience of processing, transportation, and on-site construction, develops the brick and mold simultaneously, improving upon the shortcomings of existing molding mold technology, such as large space occupation, poor stacking stability, inconvenient transportation, and inflexible reusability. The mold is made of lightweight rigid ABS plastic with a hollow internal structure, facilitating interlocking and stacking for transportation. A single brick is organically separated into two identical mold units, which are then rotated 180° symmetrically, interlocked, and anchored together from the sides, significantly saving transportation space and weight, and reducing transportation costs.
