Abstract

The manufacture and design of a novel reinforced cement composite material (10) comprising seamless, elongated, integrally perforated tubular metal steel bars (20) with a triangular cross-section constrained topology configured with three consecutive parallel interconnected solid rod-like portions located at the apex of the triangle as longitudinal reinforcing phases (21), multiple perforated mid-span shells as anchoring phases (22), and a permeated heterogeneous blended adjustable low-heat-of-hydration, high-elasticity-modulus hydraulic binder material as a matrix phase (40). The composite material is characterized by a unique core-radial, axial-aligned, distributed mechanically bonded anchoring tenon mesh (41) which, during the curing of the hydraulic binder composite material, is influenced by multiple honeycomb matrix tenon cells (42) formed in collaboration with annular honeycomb-shaped constraining stirrups along the perforated mid-span shells and used in conjunction with a multilayer perforated metal plate as a transverse reinforcing phase (30) for the manufacture of various three-dimensional steel mesh constrained cages in reinforced solid concrete elements for constructing buildings and civil structures.

Description

Invention Field

[0001] This invention broadly relates to a novel reinforced cement composite system featuring a new interlocking structured rebar network combined with a permeated, non-uniformly mixed hydraulic material, replacing the ribbed solid metal reinforcing bars currently widely used in the construction industry to form concrete structural members. Clearly, this invention allows for the realization of novel elastically reinforced cement composites with high mechanical bonding properties through the use of an interlocking hydraulic material matrix dowel approach, and high deformation / ductility properties through the use of triangular perforated tubular rebar structures with multiple layers of perforated metal plates.

[0002] Existing technologies for reinforcing cement composite materials

[0003] The technology of reinforced concrete composite materials is well-known and widely applied in the construction industry, and its advantages lie in the fact that ribbed steel bars provide tensile strength to concrete structures and supplement the compressive strength of concrete. However, under high dynamic lateral loads such as earthquakes, even with the constraint of the reinforcing steel system, the steel reinforced by ribbed steel cages can undergo severe deformation or bending.

[0004] Reference Figure 1 , 2aFigures 2b and 2b illustrate typical ribbed solid and / or hollow reinforcing bars with different polygonal cross-sectional shapes, demonstrating a typical prior art method for forming structural concrete members by bonding and securing the reinforcing bars to the core periphery of the solid and / or hollow bars using a hydraulic adhesive matrix material. However, buckling of the rebar rod under high dynamic lateral loads remains an unresolved and recognized drawback of single solid / hollow reinforcing bars, primarily due to their low moment of inertia, ineffective anchorage mechanisms, shear stress dimensional hysteresis, and large elastic modulus mismatch between the reinforcing bar and the surrounding cementitious matrix. In a more specific sense, the novel perforated tubular monolithic architected rebar proposed in this invention, together with the infiltrated normal strength high elastic modulus hydraulic binder matrix, not only retains all the important advantages provided by traditional solid composite rebar, but also significantly and correctly solves the aforementioned problem of mismatch between the elastic modulus of single solid / hollow rebar, while introducing new mechanisms in the interfacial bonding of the rebar matrix and the lap splicing of the rebar.

[0005] In the construction industry, the technology of using multi-layered steel mesh structures as welded steel mesh solid rods to prepare concrete products is commonly referred to as steel-cement laminate. Figure 3c Among them, the most famous high-performance product is DUCON. However, its main applications are in seamless flooring and concrete repair. Research progress on alternative improvements to steel-cement laminates is also highly anticipated.

[0006] As is well known, there has been significant progress in the research of high-performance thin sandwich composite panel systems, such as steel-concrete-steel (DSC) hybrid panels. Figure 3a and 3b It is typically constructed with double-layered steel plates as reinforcement layers, sandwiched between Portland cementitious substrates using welded steel columns as shear stress connections. However, welding fatigue is one of the major defects that frequently occurs in thin-plate sandwich composites during their service life. Furthermore, due to the fire resistance requirements of the outermost double-layered metal plates, the specific welding procedures specified for installing the steel shear bolts, and fatigue issues, the widespread use of DSCs in the construction market is very limited.

[0007] Therefore, there remains a need in the field for reinforced laminated structural materials that can be used in current structural application design specifications, while eliminating the aforementioned limitations, particularly those of cement-reinforced laminates, and exhibiting high destructive toughness and low heat of hydration during curing.

[0008] Key issues in the current development of reinforced cement composite materials

[0009] Building and civil engineering structures, such as buildings and bridges, typically employ reinforced concrete structures. In reinforced concrete structures, steel reinforcing bars are embedded in cast concrete. These bars provide tensile strength to the concrete structure and supplement its compressive strength. However, the reinforcing bars / cages can deform or twist, leading to unnecessary deformation of the resulting reinforced concrete structure. Simultaneously, stringent wind and seismic design is implemented, and design codes for reinforced concrete with details regarding transverse reinforcement have been developed and widely applied to meet the higher ductility requirements of reinforced concrete. Current status of reinforced cementitious composites is limited to using cross-tie loop bars in combination with single solid / hollow reinforcing bars as confining reinforcement, and the buckling problem of solid reinforcing bars under seismic loads remains unresolved. Notably, with the increase in the diameter of traditional solid composite reinforcing bars, the "shear stress hysteresis" problem leads to a disproportionate increase in core strength and a combined negative impact of losing core area efficiency in terms of strength and load handling. Another common practice to improve the ductility of reinforced concrete is to add metal fibers to prevent cracking, but the effect is limited unless the fiber content is very high. The main drawback of traditional solid steel reinforcement is largely due to its "buckling" limitation, which, importantly, is now successfully addressed by the features of the current, soon to be more fully disclosed, composite steel reinforcement invention of a "perforated-tubular" two-main-component apex solid / mid-span shell.

[0010] Interestingly, the apparatus and related manufacturing methods for manufacturing the novel perforated tubular steel reinforcement structure proposed in this invention significantly enhance the manufacturability of the invention and strengthen its application in this field.

[0011] Another aspect of this invention is the development of a concept for an elastically reinforced monolithic laminated composite material based on a three-dimensional tension-interlocked confined steel cage. By customizing a non-slip topological interlocking mechanism, delamination failure caused by the propagation of interfacial cracks between the reinforcing phase and the matrix phase of the reinforced cement composite material can be mitigated. Furthermore, by confining the steel cage, the permeated cement matrix is ​​segmented into hard and soft phases, further transforming their respective structural properties into advanced composite materials.

[0012] The three-dimensional tension interlocking confined steel cage of this invention uniformly utilizes the entire capacity of the continuous reinforcing phase from the inside out. Unlike the frictional force between traditional steel bars and the matrix, interfacial bonding is not the primary factor in force transmission in this novel elastic reinforced composite system. Instead, the interlocking and distributed anchoring force transmission mechanism between the three-dimensional reinforcing phase and the penetrating high-elasticity modulus matrix binder invokes a completely rigid composite effect.

[0013] Further detailed descriptions of these new features and advantages will be given in their respective summaries below, and will also be given in the detailed description of the invention thereafter. Summary of the Invention

[0014] Characteristics of novel reinforced cement composite systems

[0015] From a systems perspective, the present invention can be described as a composite steel mesh material system comprising: (a) an elongated triangular perforated tubular rebar structure and a functionally defined collar-sleeve fitting joined to the perforated triangular tubular rebar element; (b) a perforated honeycomb transversely reinforcing metal plate for arranging multiple perforated triangular tubular rebars to form a steel mesh; and (c) a low-heat-of-hydration, high-elasticity-modulus-permeable cementitious matrix embedded in the perforated triangular tubular rebar element / mesh.

[0016] In addition to the aforementioned system perspectives, this invention also proposes a novel composite material anchoring mechanism to replace rib bonding, which is achieved by a tenon-and-mortise interlocking mechanism between a triangular perforated tubular steel mesh and a high-elasticity modulus permeable matrix, along with transversely spaced perforated honeycomb reinforcing plates, replacing transverse steel bars.

[0017] Another feature of the present invention is a method for constructing a structural system with high deformability and ductility, which has a novel steel reinforcement topology configuration that enables better bond strength and shorter development length through distributed perforation and apex material-volume usage.

[0018] Tubular composite apex solid / mid-span shell reinforced structure

[0019] According to a preferred and optimal embodiment of the present invention, from a structural and product perspective, a uniformly formed, slender, hot-extruded tubular metal reinforcement composite structure with a long axis is proposed, comprising (a) three interconnected, continuous, solid rod portions at the apex as a reinforcing phase, (b) a plurality of perforated mid-span shells serving as an anchoring phase along the length of the reinforcement, (c) profiled head portions serving as splicing connection phases, and (d) hot-extruded tubular metal collars-sleeves serving as contact-lapping phases. Preferably, the hot-extruded tubular reinforcement and the collar-sleeves are triangular prisms, and the perforated mid-span shell structure has longitudinally patterned square tenon holes. Constructed integrally with and as part of the preferred triangular perforated tubular reinforcement, it synergistically provides significant performance advantages over all known solid steel reinforcement structures. The triangular perforated tubular reinforcement has a construction that centrally defines the apex solid / mid-span shell binding combination of the steel-reinforced structure of the present invention, including unique buckling load management, maximum material-moment of inertia distribution to offset the shear stress hysteresis problem faced by designers in the "size effect" dilemma of conventional solid steel reinforcement, and a high interface mechanical bonding / anchoring mechanism to effectively maintain good internal consistency with the penetrating cement matrix material.

[0020] Importantly, the seamless, integral anti-buckling bandage nodal zone, existing between the continuous apex solid reinforcement phase and the mid-span shell already produced from a single hot extrusion process, possesses the endless hoop confinement capability to suppress the load-bearing capacity of matrix expansion and effectively guide it into the long, linearly axially extending, tensioned apex corner rods present in the steel reinforcement structure.

[0021] In the proposed preferred embodiment of the reinforced structure, the dimensions of the continuous apex solid portion (8mm-16mm) are effectively adjusted to achieve sufficient failure toughness, while minimizing the lap-length parameter, which is considered to be 40 times the diameter of the reinforcing bar in the design standard.

[0022] Splice Connector and Triangular Reinforcing Mesh

[0023] Another key feature of the invention is that, for effective and innovative use, a tight insertion connection is provided by a perforated triangular tubular collar-sleeve on the two irregular double-ended ends of two perforated triangular tubular steel bars with the same external dimensions.

[0024] In the steel reinforcement structure of this invention, the collar-sleeve itself can independently function as a sheath-structure, possessing a physical form and performance similar to an offset-dimensionality extend structure. This innovative connection mode facilitates and reduces the assembly cost of the steel reinforcement structure of this invention, and can be described as a contact lapping splicesleeve in an integral form associated with interlocking tenons.

[0025] Another very interesting feature of the perforated triangular tubular steel reinforcement structure of this invention is that it can be effectively assembled into a steel mesh structure simply by inserting multiple layers of perforated honeycomb metal plates as transverse reinforcement. Not only is this feature of the invention itself interesting, but the honeycomb transverse reinforcing metal plates, used as embedded "internal endless loop" reinforcement, greatly avoid the expansion phenomenon of the permeable cement matrix that usually occurs under seismic loading. The novel embedded assembly model of this invention, through the combination of modular steel mesh cages, can significantly improve construction efficiency, shorten the construction cycle, and facilitate on-site assembly.

[0026] Synergistic Permeable Matrix Filler

[0027] As described above, the present invention also proposes a permeable, low-heat-of-hydration, high-elasticity-modulus cementitious matrix, which forms an interlocking tenon mesh for interfacial bonding and an anchoring mechanism within the novel reinforced composite material. This high-elasticity-modulus matrix plays a crucial role in the deformation and ductility properties of the present invention in structural applications. In other words, as a permeable inorganic hydraulic binder-based material, the low yield stress rheological mixing properties of the fresh paste and the high elasticity-modulus properties of the hardened paste are both essential in the matrix structure of the proposed preferred embodiment.

[0028] In existing technological practices, it will be noted that achieving high modulus of elasticity concrete using conventional cementitious matrix mixing methods will result in an increase in the modulus of elasticity of concrete with aggregates and / or compressive strength grades exceeding 100 MPa. However, when the compressive strength grade of concrete exceeds 80 MPa, the significant release of binder hydration heat during hardening is a major problem leading to internal cracking of the concrete, unless appropriate cooling procedures are implemented for drying curing, or even mandatory fiber reinforcement is mandated in building codes to prevent cracking exposed to fire.

[0029] For reasons not yet fully understood but unexpected, the unique ternary composite binder of this invention contains ultrafine ground blast furnace slag (UFGGBS), with the UFGGBS content being 15%-35% by weight of the total binder, more preferably 25%-35%, and a water / binder ratio of 0.28-0.32. For ordinary grade 60 MPa compressive strength concrete, without using ultra-high strength concrete methods, it provides excellent elastic modulus enhancement properties in the 40 GPa-45 GPa range, referred to herein as the "decoupling effect." Due to the significant portion of the ultrafine slag inducing aluminosilicate bridging molecular interface strengthening effect, this novel low-heat ternary composite cementitious binder, when used with the organic osmotic spacer dispersant (hereinafter referred to as "G. Seed"), can significantly improve CASH gel morphology and bond density. By using an in-situ seeding template to control the morphology and size of the gel grains in the basic gel building blocks of CASH, they can self-assemble into microstructures with a higher bond density. Simultaneously, after the matrix solidifies, it transforms from an amorphous gel state to an ordered crystalline gel state, thus the hardened matrix is ​​very similar to the metal alloy matrix in terms of modulus enhancement.

[0030] In the proposed, preferred embodiment of the novel reinforced composite material, the high-elasticity modulus permeable cement matrix, hereinafter referred to as "Model CEM," is composed of an air-cured hydraulic active binder comprising: silicate cement (OPC), granulated blast furnace slag (GGBS) and ultrafine granulated blast furnace slag (UFGGBS), an organic osmotic spacer, fine aggregate, coarse aggregate, water, and an organic dispersant. Importantly, the preferred permeable cement matrix is ​​in the form of an optimized packing bond density paste, which is dispersed in combination with a small-molecule organic permeable spacer co-dispersant present in the freshly mixed matrix to impart a dense filler-filling effect at a low water / binder ratio.

[0031] According to the preferred embodiment, after hardening, the interfacial transition zone between the slurry and the aggregate is preferably in the form of a dense thin layer, which is generated from the pozzolanic reaction of ultrafine active hydraulic mineral fillers. This is crucial for the development of novel reinforced composite materials for distributed crack control and achieving high durability.

[0032] Constructed integral sandwich structure

[0033] As described above, this invention also proposes a novel elastically reinforced sandwich laminate composite material system. In the broadest sense, this elastically reinforced laminate composite material, characterized by a "constructed honeycomb layered material," is characterized by a "triangular interlocking material (TIM)," based on a combination of a ternary binder containing a "normal strength-high elastic modulus matrix" of ultrafine ground blast furnace slag and a three-dimensional reinforcing cage constraint mesh. This three-dimensional reinforcing cage constraint mesh originates from an assembly of aligned multiple layers perforated iso-grid patterned metal plates, which are internally tension-interlocked in at least one dimension with multiple mutually cooperating vertex solid triangular hollow reinforcing bars. Even in the event of severe damage where the matrix may fail, the vertex solid triangular hollow reinforcing bars, acting as a lateral reinforcement system in the multilayer integral sandwich composite material, counteract separation through a matrix tenon anchoring mechanism and provide strong tension interlocking.

[0034] The invention is now defined by creating a novel “Triangular Interlocking Material (TIM)” structured-structural laminate design and a predetermined topological structure method, characterized by the content described in the independent claims. Preferred embodiments of the invention are disclosed in the independent claims. In particular, the “Triangular Interlocking Material (TIM)” system originates from a combination of cells, each cell having a solid triangular cylindrical core geometry whose top and bottom surfaces are defined by annular honeycomb-shaped confining hoops based on a triangular model arranged within a two-dimensional perforated grid plate constructed of slender beams. The dimensional parameters of the cells have significant control over the development of the tenon-and-mortise properties of the cells through the constraint effect of non-slip topological interlocking action between the reinforcing structural phase and the matrix phase. This overcomes the reinforcement limitations of traditional composite materials based on the transfer of total tensile strength from bonding stress to the alloy reinforcing phase. As an effective structural material, the periodically replicated honeycomb cylindrical solid tenons of a triangular geometry (hereinafter referred to as "Triangular Interlocking Material (TIM)") with well-controlled "interlocking parameters" endow the constructed honeycomb layered material system with a tunable mechanism, precise structural performance, and function. Therefore, "TIM" can be designated as the element representing the volume (RVE) that controls and influences the mechanical properties of the composite material of this invention. The shape factor of the "Triangular Interlocking Material (TIM)" has the highest intrinsic efficiency ratio, defined as the ratio of the bonding side surface area to the cross-sectional area of ​​a cylindrical material at a given equivalent height and unit mass of matrix material. Therefore, for the same cross-sectional area, the Triangular Interlocking Material (TIM) is approximately 30% more efficient than a circular one in developing surface adhesion and significantly improves shear stress-strain capacity for a given displacement requirement.

[0035] Unlike traditional multilayer sandwich structures, the novel elastically reinforced sandwich laminated composite system of this invention is a new class of multilayer sandwich composites employing a multi-materials-structured-structures hybridization strategy. This strategy focuses on predetermined topological configurations, including honeycomb, layered, and segmented structures, to create ordered phases with varying connectivity, thereby optimally serving specific engineering purposes. In particular, this invention relates to a single-layer or multilayer sandwich composite material in which the stiffness mismatch between the reinforcing phase and the matrix phase is intentionally controlled to produce a novel elastically reinforced monolithic sandwich composite material with incredibly high strength, high flexural stiffness, high ductility, high deformation capacity, and high tolerance to localized mechanical damage with minimal mass. This innovative, achievable thin composite panel can be conceptualized as a highly improved form of permeable laminated sandwich composite material, eliminating the need for adhesives or welding techniques to bond the double outer layers to the core. In order to replace adhesive or welding methods, multiple apex solid perforated hollow steel bars are inserted as bridging anchor rods, which serve as tension interlocking connectors and spacers, to firmly bond the double sandwich outer composite panel sheet to the sandwich inner composite panel core, thereby intentionally creating a fully rigid thin-layer sandwich composite component or element thereon for general structural applications.

[0036] Apparatus for implementing a new method for manufacturing reinforcing bars and perforated plates

[0037] As described above, the present invention also proposes special apparatus for carrying out the method of the present invention in order to produce the steel reinforcement structure and perforated metal plate of the present invention.

[0038] In the device, advancing from the upstream region to the downstream region, it includes (a) a mandrel with a triangular profile having a long axis substantially coincident with the rebar forming axis, (b) an elongated hollow extrusion die operably disposed adjacent to the extrusion region, its long axis substantially coincident with the rebar forming axis, surrounding the mandrel, (c) a plurality of heaters spaced apart from each other along the rebar forming axis and arranged to be effectively adjacent to and associated with the extrusion die, and (d) a power-driven push rod that moves at a rate relative to the extrusion die to preheat the solid metal bar.

[0039] In addition, the device of the present invention also includes a fiber laser tube cutting machine having a rotatable clamp that is aligned with the forming axis of the steel bar and forming predetermined holes in a manner distributed along the length of the shell in the steel bar structure.

[0040] These and various other features and advantages provided by the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings and claims.

[0068] Best way to carry out the invention

[0069] See the attached diagram, refer first. Figure 6a The novel reinforced cement composite material, including (10), is a slender, linear composite material constructed according to a preferred and best embodiment of the invention. The triangular perforated tubular reinforcing bar (20) has... Figure 4 The long axis shown includes a continuous solid vertex reinforcement phase (21), a mid-span shell anchoring phase (22), an irregular end cap head anchoring phase (24), and a perforated honeycomb tenon hole interlocking phase (23). A permeable high-elasticity modulus matrix (40) is integrally and uniformly embedded with the reinforcing steel (20). After hardening along the length of the reinforcing steel (20), the matrix has a dense mass form, including an array of matrix tenons (42), an array of constrained matrix (41) within the reinforcing steel shell, and an array of unconstrained matrix (43). Therefore, the perforated tubular composite reinforcing steel structure proposed in this invention, when situated within a permeable high-elasticity modulus matrix, significantly contributes to the excellent longitudinal bending stability of the reinforcing steel structure. Figure 4 As shown, a set of tenon holes (23) along the mid-span shell of the steel reinforcement is the main interlocking interface for forming matrix bonding and anchorage strength, replacing the typical steel ribs along the bar surface and the hooks at the ends of the solid bar in the prior art. The main continuous solid apex (21), the perforated mid-span shell (22), and the double-end caps (24) formed by hot extrusion and fiber laser cutting are collectively referred to herein as the perforated tubular steel reinforcement structure (20).

[0070] As described above, the perforated tubular steel bar is a hot-extruded structure that, under tensile stress, exhibits the same elongation characteristics as conventional solid steel bars. The formation of the uniformly oriented, solid-corner, mid-span shell structure involves a large number of suitable metal ingots, preferably low-carbon steel, hot-extruded through a die perpendicular to the longitudinal axis of the steel bar. Those skilled in the art will readily understand that a relatively wide range of sizes of the component parts constituting the steel bar structure (20) may be available, and different sizes may be used, depending on the specific application of the structure.

[0071] Variations in the dimensions of the reinforcing steel members will naturally affect the structure's design load-bearing capacity. In fact, the entire structure is a perforated tubular structure, which largely eliminates the so-called "reinforcement dimensional shear stress hysteresis problem," a characteristic of traditional large-diameter solid reinforcing steel. Therefore, relatively large integral reinforced structures can be produced and used for high load-bearing requirements without compromising the capacity of large solid cross-section reinforcing steel.

[0072] See details Figure 4The reinforcing phase (21) is strategically positioned at the apex of the equilateral triangular cross-sectional geometry to maximize the moment of inertia of the steel reinforcement structure (20). This structure of slender solid bars (21) with three consecutive vertices connected to each other eliminates the dilemma of “shear hysteresis,” which is achieved by increasing the diameter of the steel reinforcement to achieve the desired greater strength. The triangular cross-section is defined by periodically binding the steel reinforcement with seamless, homogeneous, and circumferentially circumferentially running stirrups, which serve as nodes or bulkheads, referred to here as the binding structure. This further prevents Brazier buckling of the proposed steel reinforcement structure, thereby enhancing its deformation capacity during seismic loading.

[0073] In principle, anything that stiffens a tubular rod will increase its bending resistance, thus making it stronger in compression. Therefore, the quantum jump in strength and ductility of the proposed tubular steel reinforcement structure can be achieved by providing detailed structural efficiency through a substantially linear, solid reinforced apex capable of bearing long-axis tension, preferably made of metallic material and obtained from extrusion molding and fiber laser cutting processes.

[0074] Of particular interest regarding this capability of the bandage reinforcement structure of the present invention is that this variation in buckling resistance can be achieved without altering the volume of material occupied by the reinforcement structure within the permeable matrix in any way. In other words, it provides a remarkable counterbalance between the buckling resistance of the reinforcement and the expansion of the surrounding matrix under seismic and lateral forces.

[0075] See Figure 4 By constructing “multi-unit matrix tenon” cells (42) along the mid-span shell (23) as the anchoring phase, the long-standing problems of bond strength and anchorage development length in conventional steel ribbed steel structures can now be successfully solved by this unique feature of the invention. Importantly, the inherent efficiency in the area-to-volume ratio of the “triangular” cross-sectional shape further maximizes the bond between the proposed steel bar’s intrinsic angular surface and the permeable matrix.

[0076] By shifting the design phase of enhancing component proportions to material proportions, such as... Figure 4 and 6aThe distributed local interlocking mechanism shown follows the similarity theory of proportional changes (i.e., reinforcing phase + anchoring phase + configuration + proportion). Therefore, traditional methods for shortening the anchorage length of reinforcing bars, such as using welded anchor heads instead of end hooks, can be simplified in a more uniform way by using integrated irregular end caps (24).

[0077] The composition of the now described high-elasticity modulus matrix “model CEM” (40) is analyzed, and observations are made as follows: Figure 13a and 13b The overall composition shown includes a hydraulic mineral binder “G. Seed” (47) having a ternary mixed cementitious material (45), fine aggregate, coarse aggregate, organic dispersant, organic permeation spacer co-dispersant (46) and water.

[0078] In view of the characteristics of the high elastic modulus matrix of the present invention, in addition to the general performance characteristics required by cement composites such as concrete, it also includes low yield stress flow in the fresh state and high bond density after hardening, so as to obtain the high elastic modulus characteristics of the penetrating inorganic binder matrix.

[0079] Focusing on the composition of hydraulic mineral binders, the addition of large amounts of ultrafine active mineral fillers (UFGGBS), and the use of organic penetrating spacer co-dispersants, has led to the targeted development of high bond density with aggregates for obtaining high elastic modulus slurries. This has resulted in significant improvements over existing techniques in the use of volcanic aggregates that induce alkaline silica reactions. Another advanced alternative is the use of ultra-high strength concrete with compressive strength exceeding 80 MPa, but this requires the addition of organic fibers to control explosive cracking.

[0080] As a crucial performance factor for deformation control in novel reinforced cementitious composites, the proposed method for determining the binder density of active mineral fillers involves a modified form of the strength-elastic modulus decoupling effect. This differs from the aggregate modulus upgrading practices commonly used in strength-elastic modulus coupled hybrid designs. Figure 13c As shown.

[0081] High elastic modulus hydraulic binders, such as those already mentioned and Figure 13d The test results shown indicate that the ternary blended cement material (45) can be prepared using a specific mixture of components, including ordinary Portland cement (OPC), finely ground blast furnace slag (GGBS), and ultrafine ground blast furnace slag (UFGGBS) combined with an organic permeation spacer co-dispersant (46), which can be prepared by the following “G. Seed” formulation:

[0082] (a) 50-60 vol% silicate cement with an average particle size of 30 μm;

[0083] (b) 25-30 vol% of UFGGBS with an average particle size of 5 μm;

[0084] (c) 15-20 vol% of GGBS with an average particle size of 20 μm;

[0085] (d) The water / binder ratio ranges from 0.28 to 0.32;

[0086] (e) 0.5-2 vol% organic permeation spacer co-dispersant.

[0087] The properties of the new "modulus CEM" composite material after 28 days of normal curing are as follows: Figure 13d The test results are shown in the table. This clearly demonstrates that the CASH binder gel layer interface strengthening strategy can effectively improve the elastic modulus of cement composites without employing ultra-high strength concrete design methods.

[0088] Preferably, as shown in Figure 5, the perforated tubular steel reinforcement structure of the present invention adopts a triangular geometric cross-sectional shape, which has the highest bending-torsional stiffness. Furthermore, it has the largest area / volume ratio, maximizing the matrix permeability and flow rate ratio. More specifically, the triangular cross-sectional geometry of the preferred embodiment effectively results in an extremely strong and robust mechanical bond between the steel reinforcement structure and the permeable matrix—this bond also plays a crucial role in the stiffening of the continuous apex angle-reinforcing phase resisting buckling forces.

[0089] The splicing mechanism for triangular perforated tubular steel bars differs from the typical splicing method for traditional solid steel bars, such as... Figure 7 As shown, the collar-sleeve insertion proposed in this invention is a fundamental method that combines the joint sleeve and contact lap joint methods used in existing solid rebar joint connections.

[0090] The perforated tubular collar-sleeve is one of the most unique contributions of this invention because it works in a very special way to align the perforated tubular steel bars coaxially, thus simulating the tensile strength of continuous steel bars without joints.

[0091] As an important aspect of the above-mentioned connection method, the proposed tight insertion method includes the following steps: (a) minimizing the lap length parameter of the vertex solid angle reinforcing phase, (b) matching the external dimensions and geometry of the coaxial reinforcement structure with the internal dimensions and geometry of the collar-sleeve, and (c) achieving an interlocking connection mechanism using a permeable high elastic modulus matrix. This integral connection method differs from existing methods in that it includes a profile dual-end-cap head (24) of the perforated tubular reinforcement, which is anchored and used in conjunction with the collar-sleeve (25).

[0092] Now, attention is systematically turned to another aspect of the invention, which recognizes the opportunity provided by the perforated tubular steel reinforcement structure of the invention to systematically construct steel reinforcement assemblies, for example, (a) forming triangular steel mesh column cages, (b) forming triangular steel mesh beam cages, and (c) forming triangular steel mesh foundation cages.

[0093] therefore, Figure 6a and 6b A composite honeycomb reinforcement cage system is shown, in which multiple perforated honeycomb transverse reinforcing plates (30) are sandwiched between multiple triangular perforated tubular steel bars (20). These multi-layered, three-dimensional honeycomb composite reinforcement cage structures, also known as confined cage assemblies, collaborate with a permeable, high-modulus-elasticity matrix to provide high deformation and ductility properties of novel reinforced cementitious composites, utilizing the buckling-resistant perforated tubular steel bar structure proposed in this invention to resist wind and seismic loads acting laterally on the building (70).

[0094] like Figure 6a and 6b As shown, the three-dimensional honeycomb reinforced cage composite material (50) has at least two perforated metal plates (30) with repeating patterns of triangular annular honeycomb stirrups (31) aligned, spaced, and parallel to each other in a matching design. This allows for engagement with at least two axially aligned triangular perforated tubular reinforcing bars (20) within this reinforced cage structure, thereby forcing them together as a high-stiffness confinement enclosure to form “interlocking tenon” cells (41) distributed throughout the novel reinforced cement composite unit structure. The formed “interlocking tenon” cells effectively utilize their confinement strengthening capacity to reach the maximum yield level before matrix slippage and crushing failure occur. Therefore, the confinement is integral, allowing the composite reinforced cage to establish the highest energy absorption capacity to dissipate the forces applied to the novel reinforced cement composite element. This super-ductile capability demonstrates that the preferred embodiment of the reinforced composite material proposed in this invention functions as a whole to achieve higher levels of strength, stiffness, and elastomechanical properties in terms of compressive, wind, and seismic loads, while maintaining good internal coherence.

[0095] In a preferred embodiment, the triangular perforated tubular reinforcing bars (20) are made of hot-extruded low-carbon steel, with a total length of approximately 10-12 m and a central major axis, referred to as the reinforcing bar forming axis. Extending along the vertex angle axis is a continuous solid bar region with a diameter approximately the drawn diameter (8 mm-25 mm), which defines the effective cross-sectional area of ​​the reinforcing phase. The associated mid-span shell binding region has a thickness of approximately (3 mm-6 mm) and a width of approximately (6 mm-12 mm), which defines the effective cross-sectional area of ​​the anchoring phase. The area of ​​the annular honeycomb stirrup region is approximately (25 mm x 25 mm - 50 mm x 50 mm), which defines the effective cross-sectional area of ​​the interlocking matrix tenons.

[0096] In a preferred embodiment of the three-dimensionally constructed honeycomb steel cage composite material (50), the multilayer perforated honeycomb transverse reinforcing phase (30) has equilateral triangular stirrups (31) with a length dimension of (40mm-70mm) and small circular vertices, which are spaced apart to create an equidistant mesh topology pattern of ribs and nodes to achieve optimal local constraint effect, and the thickness of the perforated plate is approximately (2mm-5mm).

[0097] In a preferred embodiment, such as Figure 13c The permeable high-performance matrix binder material (40) shown is a high elastic modulus cement binder matrix material with a compressive strength between 60 MPa and 80 MPa and an elastic modulus higher than 40 GPa to provide the required strength, hardness and toughness ductility properties, and in order to unblock infiltration, the maximum aggregate size is limited to one-quarter of the size of the honeycomb stirrups.

[0098] In one example embodiment, the elastically reinforced composite material structure shown in Figure 8 is an elastically reinforced laminated sandwich composite material (10) having multiple perforated thin metal plates (30) with annular honeycomb equilateral triangular stirrups as a multi-layer transverse steel mesh. By matching multiple apex solid perforated triangular hollow steel bars (20) that serve as shear stress connectors with the tension-interlocked multi-layer transverse steel mesh, an elastically reinforced high-performance thin-layer sandwich composite material component is generated after infiltration of a normal-strength, high-elastic-modulus ultrafine matrix (40), thereby forming an integral three-dimensional honeycomb-shaped confined cage as the reinforcing phase.

[0099] As described below, the elastic reinforced laminate sandwich composite material (10), as shown in Figures 8, 9, 10, 11, and 12, is a three-dimensionally architected honeycomb layered composite material. It has at least two perforated metal plates (30) with repeating patterns of annular honeycomb stirrups (31) or (31a), and a set of hollow triangular metal reinforcing bars (20) with solid apex perforations as tension interlocking reinforcements. These bars are inserted at defined positions between the perforated metal plates (30), preferably arranged in a staggered configuration. Figure 8e As shown, in this aligned configuration, the patterned annular honeycomb stirrups (31) or (31a) of the multilayer perforated metal plate (30) are mutually opposed and must therefore cooperate to form a high-stiffness confinement enclosure of the “Triangular Interlocking Material (TIM)” cells (41 & 42). The formed “TIM” cells consume their reinforcing capacity to the maximum yielding level before the high-performance matrix slips and crushes. Thus, the constraint is integral, and the multilayer structural reinforcing phase can establish a higher energy absorption capacity to dissipate the dynamics applied to the composite plate. This superductivity indicates that the composite plate of the present invention, acting as a whole, achieves a higher level of strength, stiffness, and elastomechanical properties in terms of resistance to compressive, wind, and seismic loads.

[0100] This invention is based on an unexpected discovery that a uniformly distributed localized stirrup constraint effect can be synergistically generated between a core of high-performance matrix binder and an integrally continuous reinforcing structural phase characterized by annular honeycomb-like stirrups reinforced by ribs and node mesh. By purposefully interlocking multiple apex solid perforated triangular hollow tube steel bars with multi-layered perforated metal plates of functional gradients, a three-dimensional honeycomb-like steel cage phase is formed, which distributes the annular honeycomb-like triangular constraint rings into a systematically spaced three-dimensional periodic mesh pattern. Through these interlocking operations, novel building materials with continuous reinforcing and matrix phases can be prepared using conventional constituent materials, transforming their respective structural properties into advanced composite material properties. The building material of this invention, with its honeycomb and layered lattice structure designed within a sandwich hybrid material topology, achieves new elastically enhanced integral composite material properties through tension interlocking reinforcement and matrix tenon anchoring mechanisms working synergistically within the continuous matrix phase, which is divided into hard and soft phases by the honeycomb-like constrained steel cage structure. Figure 8a , 8cAs shown in 8d and 8f, the hard phases (41 and 42) consist of a cell-based solid triangular core geometry tenon matrix, while the soft phase (43) consists of a hexagonal honeycomb core geometry matrix. This combination of triangular and hexagonal regional structures in the matrix phases maximizes the interfacial strain gradient density, resulting in high back-stress work hardening, which further enhances the ductility of the laminated composite during deformation. This optimizes the design of the composite material, achieving strength, stiffness, and elasticity with minimal mass.

[0101] By following Figure 5a , 5b As shown in the design flowchart in Figure 9, the mechanical properties of the present invention can be adjusted for the intended application, and the above-described method has significant advantages in manufacturing structural components by avoiding welding and / or bonding processes, but allows for method-based embedding in order to manufacture the reinforcing steel configuration in the final desired geometry.

[0102] like Figure 6a As shown in Figure 8, multi-layered honeycomb triangular stirrup perforated plates (30) are assembled into mutually mating three-dimensional continuous reinforcing phases (50) through a simple insertion operation allowed by apex solid perforated hollow steel bars (20) derived from a complementary shape configuration, thereby completely eliminating the welding and bonding processes currently used in the production of honeycomb sandwich and DSC. This results in significant improvements to the existing technology manufacturing requirements in the design of DSC (double-skin composite) and honeycomb sandwich composites. This approach greatly reduces production costs and fully leverages the potential of simple internal assembly operations.

[0103] Finally, with the emergence of computer-aided design (CAD) and computer-aided manufacturing (CAM), such as Figure 6b The triangular perforated tubular steel reinforcement structure, collar-sleeve connector, and perforated honeycomb metal plate assembly of the reinforcing cage composite material (50) of the present invention can be automatically assembled. The perforation and cutting patterns are designed in CAD / CAM software. Then, as shown... Figure 14 , 17a As shown in 17b, this design can be used to program the cutting and milling processes. The savings in time and labor make it possible to produce a product economically. With CAD / CAM, high-volume, low-cost three-dimensional honeycomb steel cage composite materials (50) can be obtained.

[0104] Therefore, as Figure 15 , 16aAs shown in 16b, structural elements formed from multiple novel reinforced cement composite materials, such as columns, beams, and laminates, are arranged to be prefabricated pre-treated building modular components (60) manufactured in a factory and then delivered to the construction site for on-site assembly of the building (70) in the next assembly phase. The manufacturing and production process of the above-described three-dimensional architecture honeycomb layered composite material of the present invention is as follows: Figure 12 As shown, it is clearly demonstrated that the molding of the composite material did not employ welding or bonding processes. This illustrates that the invention can be easily adopted in existing prefabrication and assembly plants with only minor modifications to existing equipment, fully demonstrating the broad industrial applicability of the invention.

[0105] The current Industry 4.0 trend demands creativity in the construction sector. This cellular layered material approach to architecture cherishes and incorporates recognized manufacturing techniques and develops novel composite force transfer mechanisms to achieve innovative and exciting solutions, as illustrated in the preferred embodiment of the invention. While the preferred embodiment for carrying out the invention has been described in detail, those skilled in the art will recognize various alternative designs and embodiments for carrying out the invention as defined by the appended claims. All functional equivalents known in the art of any of these materials and methods are included in this invention. Nevertheless, we understand that other changes and modifications may be conceived and made by those skilled in the art, and we consider all such other changes and modifications to be within the scope of the invention and the appended claims.
