Description

Technical Field

[0001] The present application relates to the technical field of building components, and in particular to composite building components and construction methods thereof. Background Art

[0002] With the continuous advancement of construction technology, traditional building structures are gradually evolving towards higher strength, higher durability, and better integrity. To meet the dual demands of modern construction projects for load-bearing capacity and construction efficiency, composite building structures have emerged and are widely used in bridges, high-rise buildings, and long-span structures. Common composite structures include steel-concrete composite beams and concrete-filled steel tubular columns. The basic principle of composite structures is to combine two or more materials with different properties to fully utilize the advantages of each, such as the high tensile strength of steel and the excellent compressive properties of concrete.

[0003] In the prior art, steel-concrete composite structures typically use reinforced concrete slabs and steel beams connected by shear connectors (such as studs) to achieve shared load-bearing. This structural form improves the overall stiffness and load-bearing capacity to a certain extent. However, in actual application, existing steel-concrete composite structures still have several technical problems: First, due to the characteristics of the concrete material itself, the entire structure has a large deadweight, which limits its further application in super-high-rise or large-span structures; second, the interface between steel and concrete is prone to slippage during repeated loads or long-term use, affecting the overall stability and durability of the structure; third, when the structure is subjected to large torque, the concrete portion exhibits certain brittle characteristics, resulting in insufficient ductility, which in turn affects the safety and seismic performance of the structure. Summary of the Invention

[0004] The purpose of the present application is to provide a composite building component and a construction method of the composite building component, wherein the composite building component has strong impact resistance, good toughness and high strength.

[0005] In order to achieve the above objectives, in a first aspect, the present invention provides a composite building component, comprising: A support structure comprising a plurality of fixedly connected support plates, wherein the plurality of support plates are parallel in the length direction and radially distributed with the axis of the support structure as the center in a direction perpendicular to the length; At least one elastic member, in a direction perpendicular to the length of the support plate, ends of at least two adjacent support plates away from the axis are connected by the elastic member.

[0006] In an optional embodiment, a sleeve is further included, and the sleeve is sleeved on the elastic member.

[0007] In an optional embodiment, the sleeve is fixedly connected to the support plate.

[0008] In an optional embodiment, a connection hole is provided on the support plate to provide a mounting position for the elastic member, the inner diameter of the connection hole is D, and the distance between the connection hole and the edge of the support plate is L, wherein L≥3D.

[0009] In an optional embodiment, the inner diameter D of the connecting hole is larger than the outer diameter Q of the sleeve.

[0010] In an optional embodiment, an isolation tube is further included, and the isolation tube is sleeved on the support structure.

[0011] In an alternative embodiment, the isolation tube is poured with concrete.

[0012] In an optional embodiment, multiple groups of elastic members are arranged along the length direction of the support structure, and the elastic members in the same group are located on the same plane perpendicular to the length direction of the support structure. The distance between two adjacent groups of elastic members is A, and the length of the support structure is B, where A≤1 / 3B.

[0013] In an optional embodiment, the elastic members in one group are cross-distributed relative to the elastic members in another adjacent group.

[0014] In a second aspect, the present invention provides a method for constructing a composite building component, comprising the steps of: Connecting holes are provided on the plurality of support plates, wherein the inner diameter of the connecting holes is D and the distance between the connecting holes and the edge of the support plates is L, wherein L≥3D; Fixedly connecting the plurality of support plates to form a support structure, so that the plurality of support plates are parallel in the length direction and radially distributed with the axis of the support structure as the center in the direction perpendicular to the length; An elastic member is passed through the sleeve to form a support rod, one end of the elastic member and the sleeve is installed at the connecting hole of one support plate, and the other end of the elastic member and the sleeve is installed at the connecting hole of another adjacent support plate. At least one group of support rods is provided, and the support rods of the same group are located on the same plane perpendicular to the length direction of the support structure. If at least two groups of support rods are provided, the support rods in one group are cross-distributed relative to the support rods in the other adjacent group. The spacing between the two adjacent groups of support rods is A, the length of the support structure is B, and A≤1 / 3B; An isolation pipe is placed on the support structure, and concrete is poured into the isolation pipe.

[0015] In this application, at least two adjacent support plates are connected at ends, away from the axis, in a direction perpendicular to the length of the support plates by an elastic member. When the support plates are subjected to vibration and torque, the elastic member elastically deforms, absorbing some of the force, dispersing and buffering the vibration and torque energy. This reduces the direct impact of these external forces on the support structure, improves the toughness and strength of the support plates, effectively reduces the risk of damage to the structure due to vibration and torque, and extends the service life of the structure.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0023] In a first aspect, embodiments of the present application provide a composite building component that can be used as a support column or a load-bearing beam in a building structure. The composite building component includes a support structure and an elastic member 200 .

[0024] like Figure 3 As shown, the support structure includes a plurality of fixedly connected support plates 100, which are parallel in the length direction and radially distributed with the axis of the support structure as the center in the direction perpendicular to the length. Figure 4 The direction indicated by the middle dimension B is the length direction of the support structure and the length direction of the support plate 100 . The length direction of the support structure is consistent with the length direction of the support plate 100 , and the length of the support structure is substantially consistent with the length of the support plate 100 .

[0025] For example, Figure 3 as well as Figure 4 The embodiment in which four support plates 100 are provided is shown. The four support plates 100 are fixedly connected to form a cross-shaped support structure (or an X-shaped support structure). The fixing method is, for example, welding, bolting, or integral molding. In another embodiment, three support plates 100 are provided and fixedly connected to form a Y-shaped support structure. Of course, other numbers of support plates 100 may also be provided, such as five, six, or seven.

[0026] In the actual manufacturing process, when four support plates 100 are provided, the support plates 100 may be as follows: Figure 3The individual plates extending in a straight line as shown can also be made of angle steels, which are integrally formed. One angle steel includes two support plates 100, and two angle steels include four support plates 100. The two angle steels can be formed as follows: Figure 1 The distribution is shown in Figure 1 The structure of the support plate 100 is shown from a top view. Figure 1 In the figure, the openings of the two angle steels are facing each other, and they are fixedly connected by bolt connection or welding; of course, in the actual production process, if three support plates 100 are set, the support structure can be provided with three support plates 100 extending along a straight line, or two support plates 100 made of an angle steel and a support plate 100 extending along a straight line can be provided, and the support plates 100 extending along a straight line are fixedly connected to the angle steel to form a Y-shaped support structure.

[0027] To facilitate description and understanding of the technical solution of the present application, the technical solution of the present application is described below by taking the provision of four support plates 100 as an example.

[0028] like Figure 4 As shown, the number of the elastic member 200 is at least one, and in a direction perpendicular to the length of the support plate 100 , ends of at least two adjacent support plates 100 away from the axis are connected by the elastic member 200 .

[0029] Exemplarily, the elastic member 200 includes but is not limited to: a coil spring, a leaf spring or a steel plate spring.

[0030] Exemplarily, the elastic member 200 and the support plate 100 are connected by welding, bolt connection, or clamping.

[0031] For example, one elastic member 200 is provided, one end of the elastic member 200 is fixedly connected to one support plate 100, and the other end of the elastic member 200 is fixedly connected to another adjacent support plate 100. In other embodiments, such as Figure 4 As shown, two elastic members 200 are provided, an angle is formed between the two elastic members 200 , and there is a spacing or no spacing between the two elastic members 200 along the length direction of the support plate 100 .

[0032] In another embodiment, two elastic members 200 are provided, and the two elastic members 200 are parallel and symmetrically distributed. There is a gap between the two elastic members 200 or no gap exists along the length direction of the support plate 100 .

[0033] In another embodiment, Figure 1As shown, four elastic members 200 are provided, and the four elastic members 200 are provided on four support plates 100 in a U-shaped distribution. The four elastic members 200 can be divided into two groups, and two elastic members 200 in relative positions form a group. The elastic members 200 in different groups are on different planes, that is, the elastic members 200 in different groups have a spacing along the length direction of the support plate 100.

[0034] In this application, the support structure is composed of multiple support plates 100 that are parallel in the longitudinal direction and radially distributed perpendicular to the longitudinal direction with the axis as the center. This radial layout enables the support structure to disperse and withstand external forces from multiple directions. Whether it is vertical pressure from above or lateral thrust, it can be evenly transmitted through each support plate 100, effectively improving the overall load-bearing capacity of the composite building component when used as a support column or load-bearing beam, and enhancing the stability of the structure in complex load-bearing environments.

[0035] In the present application, at least two adjacent support plates 100 are connected at ends away from the axis in a direction perpendicular to the length of the support plates 100 by an elastic member 200. When the support plates 100 are subjected to vibration and torque, the elastic member 200 can elastically deform, absorbing part of the force, dispersing and buffering the energy of the vibration and torque, thereby reducing the direct impact of these external forces on the support structure, improving the toughness and strength of the support plates 100, effectively reducing the risk of damage to the structure due to vibration and torque, and extending the service life of the structure.

[0036] In order to prevent foreign matter from entering the elastic member 200 and affecting the elastic performance of the elastic member 200, as shown in FIG. Figure 5 As shown, in one embodiment, the composite building component further includes a sleeve 300, which is sleeved on the elastic member 200. The sleeve 300 is used to protect the elastic member 200 from external debris and enable the elastic member 200 to maintain its elastic performance.

[0037] Figure 1 The elastic member 200 is shown in a top view. Figure 2 The elastic member 200 with the sleeve 300 externally sleeved is shown in a top view. Figure 5 The elastic member 200 with a sleeve 300 on the outside is shown in a three-dimensional perspective.

[0038] The elastic member 200 absorbs vibrations and buffers external forces through its own expansion and contraction. However, debris that enters the elastic member 200 may become lodged in it, hindering its normal expansion and contraction. For example, in a coil spring, debris may become lodged between the coils, preventing the spring from compressing and extending freely; in a leaf spring, debris may affect its bending and rebound. The sleeve 300, which fits over the elastic member 200, effectively blocks the ingress of external debris, ensuring that the elastic member 200 maintains smooth expansion and contraction in all environments, allowing it to stably function.

[0039] Debris not only affects the elasticity of the elastic member 200 but can also cause physical damage. Sharp debris can scratch the surface of the elastic member 200, while corrosive debris can erode the material of the elastic member 200, causing it to lose strength, weaken its elasticity, or even break. The protective function of the sleeve 300 reduces contact between the elastic member 200 and foreign debris, lowering the likelihood of such damage, thereby extending the service life of the elastic member 200 and reducing maintenance and replacement costs.

[0040] To further increase the strength and toughness of the support structure, in one embodiment, the sleeve 300 is fixedly connected to the support plate 100 so that the sleeve 300 can support the support plate 100 and improve the deformation resistance of the support plate 100.

[0041] The sleeve 300 and the support plate 100 are fixed to each other by, for example, welding or clamping.

[0042] After being fixedly connected to the support plate 100, the sleeve 300 can provide additional support for the support plate 100. When subjected to external forces, the sleeve 300 can share some of the load acting on the support plate 100, reducing stress concentration within the support plate 100 itself. This enhances the support plate 100's resistance to bending and deformation, allowing the entire support structure to withstand greater pressure and loads. For example, when a building is subjected to external forces such as strong winds or earthquakes, the fixed sleeve 300 can effectively prevent the support plate 100 from excessive bending or breaking.

[0043] The presence of the sleeve 300 gives the support structure greater resilience when subjected to stress. When subjected to impact or dynamic loads, the sleeve 300 and the support plate 100 elastically deform, absorbing and dissipating energy and preventing sudden structural failure due to excessive localized stress. This resilience helps improve the structure's seismic and impact resistance, extending its service life.

[0044] In order to provide an installation position for the elastic member 200, as Figure 3As shown, in one embodiment, a connection hole 110 is provided on the support plate 100 to provide an installation position for the elastic member 200, and the end of the elastic member 200 is fixedly installed at the connection hole 110 of the support plate 100, and the fixing method is, for example, welding, clamping or bolt connection.

[0045] like Figure 3 As shown, in order to prevent the elastic member 200 from deforming the connection hole 110 of the support plate 100, the setting position of the connection hole 110 must at least meet the following requirements: L≥3D, where the inner diameter of the connection hole 110 is D and the distance between the connection hole 110 and the edge of the support plate 100 is L.

[0046] Dedicated connection holes 110 are provided on the support plate 100 to provide mounting locations for the elastic member 200, allowing the elastic member 200 to quickly and accurately locate a fixing point during installation. Construction personnel can precisely secure the ends of the elastic member 200 based on the location of the connection holes 110, avoiding blind groping and positional deviation during installation, and improving installation efficiency and accuracy.

[0047] The location of connection hole 110 must satisfy the requirement "L ≥ 3D" (the inner diameter of connection hole 110 is D, and the distance between connection hole 110 and the edge of support plate 100 is L). This effectively prevents the elastic member 200 from generating excessive tensile force concentration on connection hole 110 when subjected to stress. When the elastic member 200 expands or contracts or is subjected to external force, if connection hole 110 is too close to the edge of support plate 100, the tensile force may cause deformation or even tearing of the material surrounding connection hole 110. Meeting this distance requirement can more evenly distribute the tensile force over a larger area of support plate 100, reducing local stress concentration, thereby preventing deformation of connection hole 110 and ensuring the structural integrity of support plate 100.

[0048] In order to provide a mounting location for the sleeve 300, as Figure 5 As shown, in one embodiment, the inner diameter D of the connection hole 110 is greater than the outer diameter Q of the sleeve 300. Exemplarily, the end of the sleeve 300 is fixed to the connection hole 110 of the support plate 100 by welding.

[0049] The inner diameter D of the connection hole 110 is larger than the outer diameter Q of the sleeve 300, creating ample space for the installation of the sleeve 300. During installation, construction workers can easily insert the sleeve 300 and place it in the appropriate position without worrying about installation difficulties or even failures due to size mismatches. This greatly improves installation efficiency and reduces installation time and labor costs.

[0050] In order to reduce corrosion of the supporting structure and increase its service life, such as Figure 1 and Figure 2As shown, in one embodiment, the composite building component further includes an insulating tube 400, which is sleeved on the supporting structure.

[0051] Exemplarily, the isolation tube 400 is made of glass fiber reinforced plastic. In other embodiments, the isolation tube 400 is made of metal material, such as aluminum alloy, stainless steel, or cast iron.

[0052] In a building environment, support structures may be exposed to various corrosive media, such as moisture, oxygen, acidic or alkaline gases in the air, and salt and chemicals in the soil. Isolation tube 400, installed on the support structure, forms a physical barrier, effectively preventing these corrosive media from coming into direct contact with the support structure, thereby significantly reducing the likelihood of corrosion. For example, in humid coastal areas, where the air contains high levels of salt and moisture, isolation tube 400 prevents these substances from corroding the support structure, potentially preventing rust and corrosion of the metal support structure.

[0053] When a support structure is composed of dissimilar metal materials or in contact with surrounding metal components, electrochemical corrosion cells can easily form in a humid environment, leading to increased localized corrosion. Isolation tube 400 isolates the support structure from surrounding metal components that may generate a potential difference, destroying the conditions for electrochemical corrosion and thus preventing the occurrence of electrochemical corrosion and protecting the integrity of the support structure.

[0054] Because isolation tube 400 effectively reduces the support structure's contact with corrosive media, it significantly slows the rate of corrosion of the support structure. Corrosion is one of the main causes of performance degradation and strength loss in structural materials. Slowing the corrosion rate means the support structure can maintain its original mechanical properties and structural stability for a longer period of time, thereby extending the service life of the entire composite building component.

[0055] To further enhance the strength of the composite building component, in one embodiment, the isolation tube 400 is filled with concrete. Concrete inherently has high compressive strength, and when poured into the isolation tube 400, it significantly enhances the compressive resistance of the area surrounding the isolation tube 400. When the composite building component is subjected to vertical loads, such as the building's own weight and floor live loads, the concrete-filled isolation tube 400 can better share and transfer the pressure, reducing the stress on the supporting structure. This improves the compressive bearing capacity of the entire component, enabling the building to withstand greater weight and more complex load conditions.

[0056] After concrete is poured into the isolation tube 400, it forms a composite cross-section with the tube 400. Compared to the isolation tube 400 or the supporting structure alone, this composite cross-section has a greater moment of inertia, significantly improving the component's flexural rigidity. When subjected to horizontal loads such as wind and earthquakes, the component can better resist bending deformation, maintain its shape and stability, and reduce structural damage caused by excessive bending.

[0057] In order to make the force applied by the elastic member 200 to the supporting structure more uniform, as shown in FIG. Figure 4 or Figure 5 As shown, in one embodiment, multiple groups of elastic members 200 are arranged along the length direction of the support structure, and the elastic members 200 of the same group are located on the same plane perpendicular to the length direction of the support structure. The distance between two adjacent groups of elastic members 200 is A, and the length of the support structure is B, where A≤1 / 3B.

[0058] Arranging multiple groups of elastic members 200 along the length of the support structure can disperse the forces that might otherwise be concentrated in one or a few locations to multiple locations. Each elastic member 200 bears a portion of the force, making the forces acting on the support structure more balanced. This avoids excessive force in one area while less force is applied elsewhere, thereby reducing the risk of structural deformation and damage caused by uneven force.

[0059] The same group of elastic members 200 is located on the same plane perpendicular to the length of the support structure, ensuring uniform force transmission within the same plane. The spacing A ≤ 1 / 3B between adjacent groups of elastic members 200 further ensures that the elastic members 200 are densely and evenly distributed along the entire length of the support structure, allowing for a smoother and more even transfer of load from the elastic members 200 to the support structure, improving the rationality of the structural force. The uniform distribution of multiple groups of elastic members 200 enhances the support structure's ability to resist lateral displacement. When the support structure is subjected to lateral forces, the various groups of elastic members 200 work together to resist lateral deformation, maintaining a stable support structure, reducing the possibility of lateral sway and tilt, and improving the overall stability of the structure.

[0060] In order to increase the ability of the support structure to resist forces in multiple directions, such as Figure 4 or Figure 5 As shown, in one embodiment, the elastic members 200 in one group are cross-distributed relative to the elastic members 200 in another adjacent group.

[0061] For example, Figure 4 and Figure 5 , an embodiment in which two elastic members 200 are cross-distributed is shown, and the two elastic members 200 are spaced apart in the length direction of the support structure; Figure 1 and Figure 2 , an embodiment of a cross-distribution of four elastic members 200 is shown, wherein the four elastic members 200 are arranged on four support plates 100 in a U-shaped distribution, and the four elastic members 200 can be divided into two groups, where two elastic members 200 in relative positions form a group, and elastic members 200 in different groups are on different planes, that is, the elastic members 200 in different groups have a spacing along the length direction of the support plate 100.

[0062] When the support structure is subjected to forces from different directions, the cross-distributed elastic elements 200 can disperse and buffer the forces from multiple angles. For example, when subjected to a horizontal lateral force, one set of elastic elements 200 can provide a reaction force in one direction, while another adjacent cross-distributed set of elastic elements 200 can contribute to the force sharing from another related direction. This allows the support structure to more evenly withstand lateral forces in all directions within the horizontal plane, preventing structural damage caused by excessive force in a single direction.

[0063] In practical engineering, support structures are often subjected to complex spatial forces, including horizontal and vertical forces, as well as torsional forces. The cross-distributed elastic elements 200 form a three-dimensional force network, with each group of elastic elements 200 working together to resist complex spatial forces such as torsional forces. When the support structure twists, the elastic elements 200 in different directions generate opposing torques, effectively limiting torsional deformation and improving the structure's ability to withstand complex spatial forces.

[0064] In a second aspect, embodiments of the present application provide a method for constructing a composite building component, which can be used for the construction of the composite building component of any of the above embodiments, and the steps include: S100: Figure 3 As shown, connection holes 110 are opened on multiple support plates 100 , the inner diameter of the connection hole 110 is D, and the distance between the connection hole 110 and the edge of the support plate 100 is L, wherein L≥3D.

[0065] S200: Figure 3 As shown, a plurality of support plates 100 are fixedly connected to form a support structure, so that the plurality of support plates 100 are parallel in the length direction and radially distributed with the axis of the support structure as the center in the direction perpendicular to the length.

[0066] S300: Figure 5As shown, an elastic member 200 is passed through the sleeve 300 to form a support rod, that is, the support rod includes a sleeve 300 and an elastic member 200; one end of the elastic member 200 and the sleeve 300 is installed at the connecting hole 110 of a support plate 100, and the other end of the elastic member 200 and the sleeve 300 is installed at the connecting hole 110 of another adjacent support plate 100. At least one group of support rods is provided, and the support rods of the same group are located on the same plane perpendicular to the length direction of the support structure. If at least two groups of support rods are provided, the support rods in one group are cross-distributed relative to the support rods in the adjacent other group. The spacing between the two adjacent groups of support rods is A, the length of the support structure is B, and A≤1 / 3B.

[0067] S400: Figure 2 As shown, the isolation tube 400 is placed on the support structure, and concrete is poured into the isolation tube 400.

[0068] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0069] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
