Description

Technical Field

[0001] This invention belongs to the field of cement product technology, specifically, it relates to a structurally reinforced precast cement product and method. Background Technology

[0002] Structurally reinforced cement is a type of cement-based composite material that significantly improves compressive strength, flexural strength, crack resistance, and durability by introducing reinforcing materials (such as fibers) into the cement matrix to optimize the internal structural mechanical properties. Its core design logic is to disperse stress transmission paths and inhibit crack initiation and propagation through the synergistic effect of reinforcing materials and the cement matrix, thereby meeting the higher requirements of building structures for material strength and stability. It is widely used in building scenarios such as walls, floors, pipes, and load-bearing components.

[0003] Among the many types of structurally reinforced cement, fiber-reinforced cement products have become one of the most widely used categories on the market due to the availability of raw materials and relatively simple processing. These products replace the traditional single cement matrix by adding various fibers (such as plant fibers, glass fibers, and plastic fibers) as a reinforcing phase to concrete, utilizing the high toughness and tensile strength of fibers to compensate for the brittleness and cracking susceptibility of cement materials. Among these, plastic fibers, with their advantages of low cost, corrosion resistance, and ease of industrial production, have gradually become the mainstream choice. Common products include fiber-reinforced cement bricks, cement boards, and cement pipes, which are widely used in civil construction, municipal engineering, and other fields.

[0004] However, existing fiber-reinforced cement products still face numerous technical bottlenecks in practical applications, hindering their strength improvement and performance stability: 1. Uneven fiber distribution is a prominent issue: Traditional processes often cut plastic filaments into short segments of 30-40mm and mix them into concrete. The fibers are prone to agglomeration and poor dispersion, failing to form a continuous stress transfer network. 2. Some solutions use loose clumps of plastic filaments as reinforcing fibers. While this avoids cutting waste, these clumps have an irregular structure. During concrete pouring, the fibers tend to accumulate at the bottom of the product under the impact of the slurry and gravity, resulting in sparse distribution in the middle and upper parts. This leads to an unbalanced strength distribution and insufficient crack resistance in the core stress area.

[0005] In the prior art, Chinese patent publication number CN110590255B, publication date: 2024-06-21, entitled "A High-Strength Plastic Fiber Reinforced Cement Product and Its Manufacturing Method," discloses that before the reinforcing fiber is cast, it is a loose ball of plastic filaments formed by winding at least one plastic filament, corresponding to the shape and size of a single product. During casting and after solidification, all internal gaps of the loose ball of plastic filaments are filled with concrete, and the outer periphery of the loose ball of plastic filaments is wrapped by the concrete to form the target shape of the product. The loose ball of plastic filaments is formed by continuous extrusion in a plastic extruder and cooling and shaping in its cooling water tank. A winding mold is set in the cooling water tank so that the plastic filaments are wound and shaped within the winding mold. The strength of the product is significantly improved, and there are no weak points on any side of the product, making manufacturing extremely convenient and quick. Although the above technical solution can improve the strength of cement products by setting up loose balls of plastic filaments, the arrangement of the loose balls of plastic filaments can easily lead to uneven distribution. Although support ribs are installed to support the loose plastic filament bundles, they can still easily accumulate at the bottom due to the impact of the cement slurry during pouring. In addition, the appearance, shape, size, and distribution path of each loose plastic bundle placed in the cement product are different, which leads to large fluctuations in the quality of the molded cement product and makes it difficult to guarantee the consistency of its performance. Summary of the Invention

[0006] The purpose of this invention is to provide a structurally reinforced precast cement product and method to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a structurally reinforced precast cement product, comprising a precast cement component formed by casting, and further comprising: a ribbed assembly disposed in the precast cement component, wherein the ribbed assembly is disposed in multiple layers in the precast cement component; wherein, the ribbed assembly is formed in a single-layer structure by multiple nodes in a surrounding manner, and forms several triangular structural areas; multiple intersection points are evenly distributed among the triangular structural areas on the multiple layers of the ribbed assembly, and the multiple layers of intersection points are bound together by binding members, thereby changing the height position of the intersection points in the layer, and forming a three-dimensional ribbed network structure.

[0008] Preferably, the system further includes a mold box, in which multiple connecting rods are provided, and the node is located on each connecting rod.

[0009] Preferably, the connecting rods are arranged in three groups in the horizontal direction and three in the vertical direction, with three in each group, for a total of [number] connecting rods.

[0010] Preferably, the rib assembly includes a single rib arranged radially around the connecting rod located at the center and surrounding the adjacent connecting rods, and side ribs arranged orthogonally around the connecting rod located at the center on the four adjacent connecting rods, so that the four connecting rods are connected, and an outer peripheral rib is arranged around the outer connecting rod.

[0011] Preferably, the intersection point is located at the intersection of the monofilament rib and the side rib, the triangular structure area is located in the triangular area formed by the intersection of the monofilament rib and the side rib, and the binding member includes a binding wire connected to the intersection point of the multi-layer rib assembly.

[0012] Preferably, the rib assembly includes a first oblique rib and a second oblique rib, which are wrapped around the connecting rod and in an S-shape around the node; the connecting rod at the center is respectively surrounded by a first long rib in the vertical direction.

[0013] Preferably, the intersection point is located at the intersection of oblique rib one and oblique rib two, the triangular structure area is located in the triangular area two formed by the intersection of oblique rib one and oblique rib two, and the binding member includes binding wire two connected to the intersection point of the multi-layer rib assembly.

[0014] Preferably, the rib assembly includes triangular rib one and triangular rib two respectively arranged around the first group of transverse connecting rods and the third group of transverse connecting rods, and triangular rib three and triangular rib four respectively arranged around the first group of vertical connecting rods and the third group of vertical connecting rods; triangular rib five and triangular rib six are respectively arranged between the first group of vertical connecting rods, the third group of vertical connecting rods and the second group of vertical connecting rods; and long rib two is arranged around the connecting rods in the vertical direction of the connecting rod at the center.

[0015] Preferably, the intersection points are symmetrically located at the intersection of triangular rib one and triangular rib two, and at the intersection of triangular rib three and triangular rib four, respectively. The triangular structure area is located in the triangular area three formed by the intersection of triangular rib one, triangular rib two, triangular rib three, triangular rib four, triangular rib five, and triangular rib six. The binding component includes binding wire three connected to the intersection points of the multi-layer rib assembly.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0017] 1. The core of this structurally reinforced precast cement product lies in the construction of a three-dimensional ribbed network structure. It achieves a performance breakthrough through the synergistic effect of multi-layer ribbed components. The single-layer ribbed components form multiple stable triangular structural areas through the arrangement of radial, S-shaped oblique ribs or multiple triangular rib groups, effectively dispersing local stress by utilizing the geometric stability of triangles.

[0018] 2. This structurally reinforced precast cement product features multi-layer components whose intersections are fixed and their height adjusted via binding devices, forming a conical connection structure. The triangular support area is further expanded between adjacent layers, allowing stress to be uniformly transmitted in three dimensions. This overcomes the limitations of traditional planar reinforced structures where stress is concentrated in a single direction. Compared to existing technologies where uneven fiber distribution and loose aggregate buildup lead to strength imbalances, this solution's ribbed components pre-form a stable structure that resists cement slurry impact, ensuring uniform distribution of reinforcing materials. This significantly improves the tensile, shear, crack, and impact resistance of the precast components, effectively addressing the core issues of uneven strength and easy cracking in traditional precast cement products. Furthermore, the design of the pull-out / non-pull-out connecting rods allows for selection as additional reinforcing ribs, while the slotted structure ensures the ribbed components do not loosen during removal, further guaranteeing overall structural stability.

[0019] 3. This structurally reinforced precast cement product solution achieves both precision and simplification at the production end, balancing efficiency and cost. The ribbed components rely on a 3×3 matrix arrangement of connecting rods for precise positioning, eliminating the need for complex weaving processes. Arrangement is achieved simply through wrapping and cross-binding. Whether it's a combination of radial single ribs and side ribs, or an arrangement of S-shaped oblique ribs and multi-triangular rib groups, the operation process is simple and easy to understand, lowering the production threshold and labor costs. Furthermore, this solution effectively avoids the agglomeration and waste problems that easily occur when short-cut fibers are randomly incorporated, resulting in higher material utilization. Simultaneously, no special equipment investment is required; existing production lines can be adapted, further reducing technological upgrade costs and production inputs, achieving a win-win situation of efficient production and cost control.

[0020] 4. This structurally reinforced precast cement product features three different rib arrangement methods, each with its own emphasis: the radial structure is simple and suitable for thin, medium-strength precast bricks and other products; the S-shaped oblique ribs, arranged in multiple directions, enhance shear and tensile strength and are suitable for medium-thickness precast components; the multi-triangular rib group forms a dense support network, which can meet the requirements of thick, high-strength large precast components and can be flexibly selected according to different product specifications.

[0021] 5. This structurally reinforced precast cement product features a removable / non-removable connecting rod design and an optional bottom groove, further enhancing its practicality. When retained, the connecting rod acts as a reinforcing rib; when removed, the resulting groove forms an interlocking structure with mortar and concrete during installation, improving stability. The groove can either fill to maintain a smooth surface or be retained to adapt to specific installation scenarios, meeting diverse needs in building construction. Whether for small precast bricks in civil buildings or high-strength precast components in industrial settings, this solution allows for flexible adaptation, significantly improving the product's market applicability and usage flexibility.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] Example: Refer to Figure 1 A structurally reinforced precast cement product includes a precast cement component 4 formed by casting, and further includes: a ribbed assembly disposed in the precast cement component 4, wherein the ribbed assembly is disposed in multiple layers in the precast cement component 4; wherein, the ribbed assembly is formed in a single-layer structure by multiple nodes in a surrounding manner, and forms several triangular structural areas; multiple intersection points are evenly distributed among the triangular structural areas on the multi-layer ribbed assembly, and the multi-layer intersection points are bound together by binding members, thereby changing the height position of the intersection points in the layer, and forming a three-dimensional ribbed network structure.

[0045] It also includes a mold box 5, which has multiple connecting rods 41, with nodes located on each connecting rod 41.

[0046] There are three sets of connecting rods 41 in the horizontal and three sets in the vertical directions, for a total of nine connecting rods 41. This means that the connecting rods 41 form a regular 3×3 matrix arrangement inside the mold box 5. This arrangement ensures that the connecting rods 41 are evenly distributed inside the cement precast component 4.

[0047] The ribbed assembly, acting as a reinforcing skeleton, is pre-placed inside the precast cement component 4. For example, the pre-fabricated ribbed assembly can be placed in a mold before pouring cement slurry, allowing the ribbed assembly to be completely encased within the cement matrix. Alternatively, the connecting rod 41 can be inserted into the sleeve 51 within the mold box 5, and then the ribbed assembly can be arranged around the connecting rod 41. As a preferred embodiment, the ribbed assembly can be made of materials such as plastic fiber filaments, glass fiber filaments, or polymer fiber filaments to provide sufficient tensile strength. The ribbed assembly can be arranged in two, three, or more layers to accommodate different thicknesses and strength requirements of the precast cement component 4. For example, two layers of ribbed assembly can be used for thinner precast bricks, while more layers can be used for thicker precast bricks.

[0048] In each layer of the rib assembly, the filaments are not randomly distributed, but organized through specific connection points (i.e., nodes). For example, multiple filaments can be interlaced at several predetermined points to form nodes. The filaments can be arranged around these nodes, for example, by weaving the filaments back and forth between multiple nodes to form a grid pattern. Thus, multiple triangular regions are naturally formed in a single layer of the rib assembly. These triangular structural regions are the basic mechanical units of the rib assembly and can effectively disperse local stress.

[0049] Multiple intersection points are formed by the uniformly distributed triangular structural areas on the multi-layered ribbed assembly. When the multi-layered ribbed assembly is stacked, the triangular structural areas on it will form corresponding positions in space. These intersection points are uniformly distributed in the precast concrete component 4 to ensure consistent reinforcement throughout the entire precast concrete component 4.

[0050] To secure the multi-layer ribbed components as a whole, these intersection points need to be connected. Thin metal wires, plastic cable ties, or high-strength ropes, or materials of the same material as the ribbed components, can be used as binding materials to tightly wrap or bind the intersection points of upper and lower layers or multiple layers of ribbed components together. This binding method transforms a single-layer distributed design into a three-dimensional interconnection of multi-layer ribbed components, further enhancing the structural strength of the precast concrete component 4 and ensuring a uniform distribution of structural strength. Furthermore, it ensures that the multi-layer ribbed components do not shift during casting and form a stable whole after the cement has cured.

[0051] Furthermore, by using binding elements to wrap around the junction, the height position of the layer where it meets can be changed. During the binding process, the tension of the binding elements can be controlled, or a certain external force can be applied during binding to cause the bound junction to shift vertically. For example, pressing the junction of the upper rib assembly downwards or lifting the junction of the lower rib assembly upwards will cause these junctions to no longer be strictly located on the same horizontal plane, but to form a connection with a certain height difference. Since there are multiple ribs at the junction, changing the height difference at the junction can cause the rib assembly at the junction to form a lifting structure feature and a conical shape (see reference). Figure 15 When the intersection point of the upper rib assembly points downwards and the intersection point of the lower rib assembly points upwards, then the intersection points of the upper and lower rib assembly points move closer to the intersection point of the middle rib assembly (refer to...). Figure 15 At this point, the multi-layer ribbed components are more evenly distributed in the three-dimensional space of the precast cement component 4, and the structural strength is further optimized. Since the intersection point forms a cone shape, a triangular structure area will be further formed between adjacent ribbed components, which further strengthens the role of the three-dimensional ribbed network structure in the precast cement component 4, thereby effectively improving the strength of the precast cement component 4.

[0052] Therefore, through the arrangement of the aforementioned multi-layered ribbed components, the formation of nodes, the construction of triangular structural zones, the distribution of intersection points, and the adjustment and binding of the height of the intersection points, a three-dimensional, interconnected ribbed network is ultimately formed inside the precast concrete component 4. This three-dimensional ribbed network structure is no longer a simple planar stack, but a reinforced skeleton with a regular spatial three-dimensional feel, capable of resisting external loads from multiple directions, effectively improving the overall strength and crack resistance of the precast concrete component 4. Furthermore, this technical solution, through a regular surrounding arrangement, can be manufactured without complex weaving processes, effectively saving production costs.

[0053] Compared to existing technologies that randomly incorporate chopped fibers into the cement matrix or use irregular, loose aggregates as reinforcement, this solution effectively solves the problems of uneven fiber distribution and agglomeration by pre-constructing multi-layer ribbed components and forming stable triangular structural regions within a single layer. Furthermore, in existing technologies, loose aggregates are easily impacted by slurry during casting and accumulate, resulting in high strength at the bottom and low strength at the top of the product, leading to an overall imbalance in performance. In this solution, the ribbed components form a stable planar structure before casting, effectively resisting slurry impact and ensuring uniform distribution of the reinforcement material within the precast cement component 4.

[0054] The mold box 5 is used to shape the external form of the precast cement component 4. The connecting rod 41 is a structural component located inside the mold box 5, mainly used to provide support and positioning for the ribbed assembly. The connecting rod 41 can be made of metal rod, such as threaded steel, whose material and strength are sufficient to withstand the weight of the ribbed assembly and the impact during cement pouring. The mold box 5 also contains nine inserts 51, each with a hole in the center for inserting the connecting rod 41. When the cement is in a semi-solid state, or at an appropriate time, the connecting rod 41 can be pulled out to bond the ribbed assembly to the cement.

[0055] In another configuration, the height of the connecting rod 41 is lower than the top of the mold box 5, allowing the connecting rod 41 to be submerged after cement is poured into the mold box 5. This enables the connecting rod 41 to bond with the solidified cement, acting as a reinforcing rib to further enhance the strength of the precast cement component 4. It is important to note that after demolding, multiple grooves will form on the bottom of the precast cement component 4 (the grooves are formed by the insert 51 within the cement, and the grooves do not touch the lower ribbed components, thus preventing leakage of the lower ribbed components). These grooves can be filled by subsequently pouring cement, or left unfilled. When left unfilled, the multiple grooves can accommodate mortar and concrete during the laying process, allowing the mortar to embed into the grooves to form an interlocking structure, improving laying stability.

[0056] In one implementation, refer to Figure 2 , Figure 3 , Figure 4 The rib assembly includes a single rib 1 arranged radially around the connecting rod 41 located at the center and surrounding the adjacent connecting rods 41, and side ribs 11 arranged orthogonally around the connecting rod 41 located at the center and surrounding the four adjacent connecting rods 41, so that the four connecting rods 41 are connected, and an outer peripheral rib 12 is arranged around the outer connecting rod 41.

[0057] The monofilament rib 1 is typically made of metal wire or fiber material, and its main function is to provide radial tensile and shear strength and effectively transfer stress from the central area to adjacent areas. Its "radial wrapping arrangement" can be understood as extending and fixing uniformly or non-uniformly from a central point outwards. For example, one end of the monofilament rib 1 can be fixed to the central connecting rod 41, and then stretched and wrapped around the surrounding adjacent connecting rods 41; alternatively, the monofilament rib 1 can be pre-bent into a radial shape, then fitted onto the connecting rods 41 and bound. The side ribs 11 are mainly used to connect adjacent connecting rods 41, forming a closed structural unit, thereby enhancing the overall integrity and torsional resistance of the area. The "orthogonal surrounding arrangement" refers to four connecting rods 41 perpendicular to the central connecting rod 41, with side ribs 11 arranged and fixed on these four connecting rods 41 to form a rectangular connecting frame. Alternatively, the side ribs 11 can be pre-made into a grid shape, placed on the connecting rods 41, and fixed to the connecting rods 41 by binding or spot welding. The outer peripheral ribs 12 are mainly used to define the outer contour of the rib assembly and provide edge support and overall constraint for the entire single-layer rib assembly, preventing stress concentration or deformation in the edge area. The "surround arrangement" can be understood as forming a continuous or discontinuous ring structure along the outermost connecting rod 41. For example, the outer peripheral rib 12 can be a continuous steel wire, which is wound and fixed along the outermost connecting rod 41 to form a closed ring; or, the outer peripheral rib 12 can be composed of multiple rib segments, each segment connecting to the adjacent outer connecting rod 41, together forming the outer support structure.

[0058] The above scheme effectively distributes the load in the central area to the surrounding areas by finely arranging the ribbed assembly in a single-layer structure, with the central connecting rod 41 as the core and radiating single ribs 1 to the adjacent connecting rods 41. Simultaneously, by orthogonally arranging side ribs 11 around the central connecting rod 41 and surrounding the four adjacent connecting rods 41, these four connecting rods 41 are not only connected to each other, forming a robust internal frame, but also, together with the radial single ribs 1, construct multiple triangular structural zones, significantly improving the planar stiffness and shear resistance of the single-layer ribbed assembly. Furthermore, the outer peripheral ribs 12 arranged around the outer connecting rods 41 provide boundary constraints and overall stability for the entire single-layer ribbed assembly, ensuring the shape retention and uniform stress transfer of the ribbed assembly within the precast concrete component 4. This combined rib arrangement allows the single-layer rib assembly to form a mutually supportive and synergistic whole within the grid of 9 connecting rods 41, avoiding local stress concentration and providing a solid foundation for the three-dimensional convergence and binding of subsequent multi-layer rib assemblies. This enables it to better resist the impact of cement slurry and curing shrinkage stress during the pouring process, ensuring the structural reinforcement effect of the cement precast component 4.

[0059] The intersection point is located at the intersection of the single rib 1 and the side rib 11, and the triangular structure area is located in the triangular area 15 formed by the intersection of the single rib 1 and the side rib 11. The binding component includes binding wire 14 connected to the intersection point of the multi-layer rib assembly.

[0060] The intersection point is the point where the single-wire rib 1 and the side-wire rib 11 intersect on the connecting rod 41. The ribs at the intersection point can intertwine and converge, forming key nodes within the rib assembly. These intersection points bear the load of structural forces. The triangular structural region is the basic unit providing structural stiffness and stability. By defining the triangular structural region as triangle 15 formed by the intersection of the single-wire rib 1 and the side-wire rib 11, the internal stress structure of the rib assembly is clearer, fully utilizing the geometric stability of the triangle. The binding wire 14 can be made of high-strength steel wire, plastic wire, fiber-reinforced composite material wire, or corrosion-resistant alloy wire, effectively connecting the intersection points at different levels and ensuring load transfer in the vertical direction.

[0061] In another implementation, refer to Figures 5-9 The rib assembly includes oblique rib 1 2 and oblique rib 21, which are wrapped around the connecting rod 41 in an S-shape around the node; long rib 23 is respectively arranged around the connecting rod 41 in the horizontal and vertical directions at the center of the connecting rod 41; it should be noted that... Figure 6 , Figure 7 , Figure 8 The dotted lines in the schematic diagram of the oblique rib 21 are only for visual differentiation from the oblique rib 12 to avoid confusion due to overlapping schematic diagrams, and have no other meaning.

[0062] Among them, oblique rib 1 and oblique rib 21 are specific structural units constituting the rib assembly. They are arranged in an oblique manner, providing multi-directional tensile and shear resistance, helping to disperse stress over a larger area and avoid local stress concentration. When the connecting rod 41 is located in the precast concrete component 4, oblique rib 1 and oblique rib 21 surround the connecting rod 41, ensuring a strong connection point between the rib and the connecting rod 41, making the connecting rod 41 the anchor point of the rib network and effectively transferring loads. Long rib 1 23 is based on the connecting rod 41 at the center and connects to the connecting rods 41 in the transverse and longitudinal directions to improve overall stability and divide multiple triangular areas 25.

[0063] The intersection point is located at the intersection of oblique rib 1 2 and oblique rib 21, and the triangular structure area is located in the triangular area 25 formed by the intersection of oblique rib 1 2 and oblique rib 21. The binding component includes binding wire 24 connected to the intersection point of the multi-layer rib assembly.

[0064] The intersection point is formed by the intersection of oblique rib 1 (2) and oblique rib 21 (21) on a plane. Binding wire 24 connects the intersection points at different levels into a unified structure, creating a unified three-dimensional rib network structure that enhances the overall tensile and shear strength. The triangular structure area is a triangular region formed by the rib segments within the rib assembly. Its function is to utilize the inherent stability of triangles to effectively disperse and transfer stress, thereby enhancing the shear and tensile strength of the precast cement component 4.

[0065] Therefore, this scheme introduces oblique rib 1 2 and oblique rib 21 into a single-layer ribbed assembly within a frame composed of nine connecting rods 41, and arranges them in an S-shape around the connecting rods 41, thus forming a ribbed assembly with multiple triangular structural zones. The oblique arrangement of oblique rib 1 2 and oblique rib 21 allows the ribbed assembly to form a multi-directional reinforcing grid in the plane, effectively resisting shear and tensile forces from different directions and enhancing the in-plane stiffness of the single-layer ribbed assembly. Furthermore, the intersection points of the multi-layer ribbed assembly are connected by binding wire 24, forming a more compact and continuous three-dimensional reinforcing skeleton. This allows the entire precast concrete component 4 to effectively transfer force to the entire three-dimensional network when subjected to vertical loads and bending moments, improving the overall bending, shear, and impact resistance.

[0066] In one implementation, reference Figures 10-12 The rib assembly includes triangular ribs 31 and 32 respectively arranged around the first and third sets of horizontal connecting rods 41, and triangular ribs 33 and 34 respectively arranged around the first and third sets of vertical connecting rods. Triangular ribs 35 and 36 are respectively arranged between the first and third sets of vertical connecting rods 41 and the second set of vertical connecting rods 41. Long ribs 38 are arranged around the connecting rods 41 vertically at the center. It should be noted that... Figure 11 , Figure 12 The broken lines are only for visual differentiation to avoid confusion due to overlapping diagrams, and have no other meaning.

[0067] Among them, triangular wire ribs 1 (31), 2 (32), 3 (33), 4 (34), 5 (35), and 6 (36) are filamentous or linear components used to enhance the structural strength of the precast concrete component 4. These ribs form a stable triangular structure in the precast concrete component 4 to effectively resist tensile and shear stresses. These triangular wire ribs can be formed between the connecting rods 41 by pre-weaving or by winding or binding during installation. Furthermore, forming the rib assembly using triangular wire ribs is simple to operate and reduces the likelihood of missing areas.

[0068] The first horizontal connecting rod 41, the third horizontal connecting rod 41, the first vertical connecting rod 41, the third vertical connecting rod 41, and the second vertical connecting rod 41 refer to specific positions among the nine connecting rods 41 arranged in a 3x3 grid within the mold box 5 (see reference). Figure 11 As shown, it should be understood that this grouping is for ease of expression only and does not constitute any other limitation. These connecting rods 41 serve as anchor points for the rib assembly, ensuring that the ribs maintain their preset position and tension during casting. The long ribs 38 are arranged perpendicular to the plane of the connecting rods 41 at the center, mainly to provide strength at the planar level.

[0069] This scheme constructs a highly optimized and uniformly distributed three-dimensional ribbed network structure by finely arranging triangular ribs 1 to 6 to 36 and long ribs 2 to 38 within the grid of connecting rods 41 inside the precast concrete component 4. Specifically, triangular ribs 1 and 2 form a transverse triangular support structure between the first and third transverse connecting rods 41, effectively resisting transverse shear forces. Simultaneously, triangular ribs 33 and 4 form a vertical triangular support between the first and third vertical connecting rods 41, enhancing longitudinal shear resistance. Furthermore, triangular ribs 5 and 6 form a denser triangular region between the first, third, and second vertical connecting rods 41, ensuring structural stability in the central region. In addition, long ribs 2 to 38 are arranged vertically along the central connecting rod 41, providing additional axial tensile strength and bending stiffness to the precast concrete component 4. This combination of multi-layered, multi-directional triangular and long ribs allows the entire rib network to more effectively distribute external loads in all directions, avoiding localized stress concentration. When the precast concrete component 4 is subjected to external impact or bending, these high-strength ribs can quickly bear tensile stress, limiting crack propagation and thus significantly improving the overall stiffness, crack resistance, and durability of the precast concrete component 4. Multiple intersection points formed by the evenly distributed triangular structural areas on the multi-layered rib assembly are bound together by tie-ins, changing the height position of the intersection points within their respective layers. This further tightly connects these finely arranged rib structures in three-dimensional space, forming a collaborative whole, enabling the precast concrete component 4 to exhibit superior mechanical properties under complex stress environments.

[0070] Reference Figure 11 The intersection points are symmetrically located at the intersection of triangular rib 1 31, triangular rib 2 32 and triangular rib 33, triangular rib 4 34 respectively. The triangular structure area is located in the triangular area 390 formed by the intersection of triangular rib 1 31, triangular rib 2 32, triangular rib 33, triangular rib 4 34, triangular rib 5 35 and triangular rib 6 36. The binding component includes binding wire 39 connected to the intersection point of the multi-layer rib assembly.

[0071] The intersection point is a crucial location for binding and connecting the multi-layer ribbed components, and also a key node for enhancing the strength of the cement product. Located at the intersection of the triangular ribs, it ensures the structural stability of the ribbed component in the plane and provides a clear anchoring point for subsequent interlayer connections. The triangular area 390 formed by the intersection of triangular ribs 31, 32, 33, 34, 35, and 36 has multiple triangular areas. Compared to the two implementation schemes mentioned above, this implementation scheme has more and more refined triangular structural areas, resulting in higher structural strength in the plane. When the multi-level intersection points are connected by binding wire 39, numerous triangular structural regions are formed in three-dimensional space, further enhancing the structural strength of the resulting precast cement component 4. This structure not only enhances the planar stiffness of the single-layer ribbed component but also significantly improves the overall structural strength and stability of the entire precast cement component 4 through precise interlayer connections.

[0072] Among them, the intersection points between triangular wire rib 1 31, triangular wire rib 33, and triangular wire rib 5 35 and the intersection points between triangular wire rib 1 31, triangular wire rib 4 34, and triangular wire rib 6 36 are connected by intersecting wire rib 37, forming a rectangular structural area on the plane. This setting can form a more stable structural area in the middle region of the cement precast component 4.

[0073] It should be understood that the aforementioned ribs can be composed of single or multiple strands of filaments. Furthermore, when winding the multi-layer rib assembly, the rib assembly can be wound first near the upper end of the connecting rod 41, and then pushed down to the desired position after winding. This makes it easier for the rib assembly to be wound on the connecting rod 41.

[0074] Furthermore, the rib assembly simplifies the winding method by using radially arranged single ribs 1, S-shaped oblique ribs 1 and 21, and triangular rib groups arranged in multiple triangular patterns. This eliminates the need for complex winding paths and methods, making the product easier to implement and further reducing manufacturing costs. Specifically, the radial structure (single rib 1 + side ribs 11) is simple and suitable for thin precast components with moderate strength requirements; the S-shaped oblique ribs, through multi-directional inclined arrangement, enhance shear / tensile resistance and are suitable for medium-thickness precast components; the triangular rib groups form a denser triangular structure area, suitable for high-strength, thick precast components. All three share the connecting rod matrix 41 and the intersection point binding design concept, allowing for flexible selection based on product requirements and expanding the applicability of the solution.

[0075] In one implementation, refer to Figure 13 , Figure 14When the connecting rod 41 needs to be pulled out, a groove 42 is provided on the outer periphery of the connecting rod 41. The groove 42 is composed of a continuous straight edge 421, a vertical edge 422, and a slanted edge 423. The vertical edge 422 and the slanted edge 423 are formed by extending into the interior of the connecting rod 41, thus forming a groove 42 that can prevent the ribs from moving up and down.

[0076] When the connecting rod 41 is pulled out from above, the following is adopted: Figure 13 In this arrangement, the inclined side 423 is located below the straight side 421. When the connecting rod 41 is pulled upward, the rib can be disengaged along the inclined side 423, and the rib will not get stuck on the connecting rod 41.

[0077] Similarly, when the connecting rod 41 is pulled out from under the mold box 5, the following is adopted: Figure 14 Arrangement method. It should be noted that when pulling out the connecting rod 41 from above or below, one end of the connecting rod 41 must extend beyond the mold box 5 to facilitate its removal. Also, when using... Figure 14 When connecting rod 41 is shown, the method of wrapping the upper end with the push-down rib assembly is not required to avoid jamming and preventing it from being pushed down.

[0078] When the connecting rod 41 does not need to be pulled out, conventional threaded steel can be used.

[0079] In addition, when the connecting rod 41 is not pulled out, the rib can be made of a material with a certain degree of elasticity. However, when the connecting rod 41 needs to be pulled out, the rib cannot be made of a material with elasticity to avoid the rib assembly structure becoming loose and failing when pulled out.

[0080] Furthermore, to enhance the stability of each connecting rod 41 and prevent tilting when pouring concrete into the mold box 5, a cover plate is provided at the upper opening of the mold box 5. The cover plate has holes corresponding to the connecting rods 41. After the rib assembly is arranged, the cover plate is placed on the mold box 5, and the top of the connecting rod 41 enters the hole to limit the position of the connecting rod 41. In addition, a pouring inlet is also provided on the cover plate to facilitate the pouring of concrete into the mold box 5.

[0081] Example: A method for manufacturing a structurally reinforced precast cement product, comprising the following steps:

[0082] S1. Prepare a mold box 5 that is compatible with precast cement products. Set up connecting rods 41 in the mold box 5 in an array of three groups horizontally and three groups vertically.

[0083] S2. Arrange multi-layer rib components on the connecting rod 41 inside the mold box 5, and connect the intersection points of the multi-layer rib components with binding parts. Adjust the binding force to change the height position of the intersection point in the layer, and finally form a three-dimensional rib network structure.

[0084] S3. Pour concrete (which may contain cement, water, gravel, sand, etc.) into mold box 5 to ensure that the concrete fills all the internal gaps of the three-dimensional ribbed network structure, and let it stand until the concrete solidifies and hardens.

[0085] S4. Demold after the concrete has completely hardened.

[0086] In step S1, one end of the connecting rod 41 is inserted into the sleeve 51 at the bottom of the mold box 5. When the concrete is half solidified, the connecting rod 41 is pulled out completely, or the height of the connecting rod 41 is lower than the top of the mold box 5 so that the concrete can completely submerge the connecting rod 41 without pulling it out. After the concrete is completely solidified, it is bonded to the cement precast component 4.

[0087] The bottom of the hardened cement precast component 4 will have multiple grooves due to the setting of the insert 51. The grooves can be filled with cement or left to be used directly, depending on the needs.

[0088] The above method can be used to easily produce cement products with structural reinforcement.

Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
