Description

Technical Field

[0001] The utility model relates to the technical field of modular buildings, in particular to a wall component suitable for modular buildings. Background Art

[0002] In traditional building construction, the pouring of concrete elements typically relies on temporary support systems and removable side forms. These side forms are installed on-site before the concrete is poured to ensure that the concrete forms the desired shape and size during the hardening process. However, this method has several major problems:

[0003] The installation and removal of the side formwork is a labor-intensive process that requires a lot of manpower and time. In addition, the repeated use of the formwork requires careful maintenance, otherwise it is easy to damage, further increasing costs.

[0004] The long preparation and disassembly time of the formwork will affect the overall construction progress, especially in projects that need to be built quickly, where this inefficiency is particularly obvious.

[0005] If the joints between the side formwork and between the side formwork and the base plate are not handled properly, gaps may appear, causing leakage during concrete pouring, affecting the appearance quality and structural performance of the components, and may also cause the concrete behind the formwork to be loose, forming a honeycomb structure. Utility Model Content

[0006] (1) Technical issues to be resolved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides a wall component suitable for modular buildings, which solves the problems of complex template installation, low construction efficiency and unstable component quality in traditional construction.

[0008] (2) Technical solution

[0009] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include: a wall component suitable for modular buildings, the wall component includes a rectangular cavity structure with an open top formed by a bottom plate and four side panels connected end to end, the two adjacent side panels are perpendicular to each other, and multiple prestressed steel bars are supported on the two opposite side panels. Concrete is poured in the rectangular cavity structure, and the prestressed steel bars pass through the concrete.

[0010] By completing the concrete pouring and prestressed steel bar installation during the factory prefabrication stage, the tedious steps of installing and disassembling formwork during on-site construction are effectively eliminated, thereby greatly saving labor costs and construction time and significantly improving construction efficiency. In addition, prefabricated components are manufactured in a controllable production environment, which can better control the pouring and curing conditions of concrete, ensure the structural strength and density of the components, avoid the common leakage and honeycombing phenomena of on-site pouring, and thus improve the appearance quality and structural performance of the components. By applying prestressing during the prefabrication stage, the bonding between the steel bars and concrete is enhanced, the tensile strength and rigidity of the wall components are improved, the occurrence of cracks in the decorative surface is effectively controlled, and the overall stability of the modular building is enhanced. The prefabricated design of the wall components makes on-site construction easier. Only the prefabricated components need to be transported to the site for assembly, which greatly reduces the complexity and uncertainty of on-site construction and reduces the difficulty of construction.

[0011] Furthermore, the wall components can be used as prefabricated lightweight partition walls, with the four side panels constructed as follows: Configuration 1 or Configuration 2. Configuration 1: All four side panels are edge angle steels, with the vertical and horizontal panels of each edge angle steel having the same length. Configuration 2: The four side panels are composed of a set of opposing edge angle steels and a set of opposing edge channel steels perpendicularly connected to the ends of the edge angle steels.

[0012] By using opposing edge angles and channels, or two sets of opposing edge angles, the assembly process of wall components is simplified, making installation more convenient and efficient. The vertical connection of the edge angles and channels provides greater structural stability, especially when subjected to lateral forces.

[0013] This design is suitable for making lightweight partition walls, which not only ensures the strength of the wall but also reduces the weight. It is suitable for application scenarios that do not need to bear heavy loads.

[0014] Prefabricated lightweight partition wall components can be quickly produced in the factory and delivered to the construction site, greatly reducing on-site installation time and speeding up the construction progress of the entire project.

[0015] The wall components can be used as prefabricated non-lightweight partition walls, with the four side panels constructed as follows: Structure 3 or Structure 4:

[0016] Structure three: The four side panels are all edge angle steels, the horizontal panels of the edge angle steels are isosceles trapezoidal panels, and the two adjacent horizontal panels are spliced ​​through the inclined surfaces of the end portions of the isosceles trapezoidal panels.

[0017] Structure 4: The four side panels are all edge angle steels, and the horizontal plates of the edge angle steels are rectangular plates. The length of the horizontal plates of the first group of relatively set edge angle steels is shorter than the length of their vertical plates, and the length of the horizontal plates of the second group of relatively set edge angle steels is the same as the length of their vertical plates.

[0018] By fixing the cross plates between mutually perpendicular edge angle steels at an angle of 40-50 degrees (the cross plates are spliced ​​by the inclined surfaces of the ends of the isosceles trapezoidal plates), or by fixing the ends of the cross plates of one edge angle steel to the vertical plates and cross plates of another edge angle steel, the structural stability and shear resistance of the wall components can be significantly improved.

[0019] The angled connection improves the wall element's ability to resist bending, which is important for non-lightweight partition walls, as they are often required to carry large loads.

[0020] Furthermore, in construction three: the inner angle of the isosceles trapezoidal plate is between 40 and 50 degrees, the longer side of the isosceles trapezoid is vertically connected to the vertical plate of the edge angle steel, and the inclined surface of the end of an isosceles trapezoidal plate is spliced ​​with another adjacent isosceles trapezoidal plate.

[0021] By vertically connecting isosceles trapezoidal plates with vertical plates, splicing the ends of isosceles trapezoidal plates at an angle, and fixing the horizontal plates and vertical plates of adjacent edge angle steels, the structural stability and shear resistance of wall components can be significantly improved.

[0022] The design of isosceles trapezoidal cross plates can improve the ability of wall components to resist bending, which is very important for non-lightweight partition walls because they usually need to carry large loads.

[0023] By connecting at a specific angle, i.e. 40-50 degrees, the structural strength of the wall components can be improved while ensuring the tightness and stability of the connection parts.

[0024] Through optimized connection methods, the performance of wall components in natural disasters such as earthquakes is enhanced, improving the safety of buildings.

[0025] Furthermore, in structure four: in the first group of relatively arranged edge angle steels, the length of the vertical plate is the same as the length of the corresponding side of the bottom plate, the length of the horizontal plate is less than the length of the vertical plate, and a yield area is formed at the end of the horizontal plate; in the second group of relatively arranged edge angle steels, the length of the vertical plate and the horizontal plate is the same as the length of the corresponding side of the bottom plate.

[0026] In two adjacent edge angle steels, the end of the horizontal plate of one edge angle steel is located in the concession area of ​​the other edge angle steel and is in contact with the horizontal plate and vertical plate of the edge angle steel where the concession area is located.

[0027] The combination of the first and second sets of edge angles significantly improves the structural stability and shear resistance of the wall component, particularly when the horizontal plates of the second set of edge angles are positioned and closely aligned with the first set's relief zones, further strengthening the structural integrity. The horizontal plates of the first set of edge angles are shorter than the corresponding vertical plates, creating a relief zone that improves the wall component's resistance to bending, a crucial feature for non-lightweight partition walls, which often bear significant loads. The horizontal plates of the second set of edge angles closely align with the first set, ensuring tightness and stability at the joint and improving the overall performance of the wall.

[0028] Furthermore, in construction one, the horizontal plates and vertical plates of the first group of relatively arranged edge angle steels are the same length as the corresponding sides of the bottom plate, and the horizontal plates and vertical plates of the second group of relatively arranged edge angle steels are the same length and shorter than the corresponding sides of the bottom plate.

[0029] In structure 2: the horizontal and vertical plates of the edge channel steel are the same length as the corresponding sides of the bottom plate, the vertical plates of the edge channel steel located in the cavity structure are provided with multiple positioning holes, the horizontal and vertical plates of the edge angle steel are the same and shorter than the length of the corresponding sides of the bottom plate, and the edge angle steel is vertically connected to the edge channel steel.

[0030] By using edge angle steel or edge channel steel as side panels and adopting a specific layout, the structural stability and shear resistance of prefabricated lightweight partition walls can be significantly improved. The vertical panels of the edge channel steel have multiple positioning holes, which can be easily fixed to the infill panels or other structural components, improving the connection tightness and structural integrity.

[0031] Furthermore, in Construction 1 or Construction 2:

[0032] The wall components also include filling plates, which are connected in sequence by plug-in and arranged longitudinally in the cavity. Connecting rods are provided at both ends of the filling plates in the longitudinal direction to cooperate with positioning holes opened on the vertical plates of the edge channel steel; there is a gap between the end of the filling plate and the edge angle steel or the edge channel steel, and the gap is filled with concrete; prestressed steel bars are longitudinally inserted into the edge angle steel or the edge channel steel and arranged in the gap.

[0033] By setting a gap between the infill plate and the edge angle steel or edge channel steel and filling it with concrete, the structural stability and shear resistance of the wall component can be significantly improved.

[0034] The filling plates are connected by plug-in and matched with the positioning holes on the edge channel steel through connecting rods, which ensures the close connection between the filling plates and improves the integrity of the structure.

[0035] By pre-setting the connecting rods and positioning holes, the on-site installation process is simplified and production efficiency is improved.

[0036] Prestressed steel bars are inserted longitudinally into the gaps between the edge angles or channel steels, which improves the performance of wall components in natural disasters such as earthquakes and enhances the safety of buildings.

[0037] Furthermore, in construction three or construction four:

[0038] The wall components also include multiple ribs and ribs, which are arranged in the cavity structure. The ribs are perpendicular to the horizontal and vertical plates of the edge angle steel and can be perpendicular to the bottom plate; the length of the ribs is the same as that of the bottom plate.

[0039] The provision of ribs and strips can significantly improve the structural stability and shear resistance of wall components, making them more capable of bearing heavy loads.

[0040] The ribs are arranged perpendicularly to the horizontal and vertical plates of the edge angle steels, which can improve the ability of the wall components to resist bending.

[0041] The length of the added ribs is the same as that of the base plate, which can ensure the uniform distribution of the internal structure of the wall components and improve the uniformity and stability of the overall structure.

[0042] Furthermore, in construction three or construction four:

[0043] The wall components also include truss bars, the lower ends of which are located in the cavity structure and abut against the edge angle steel or edge channel steel. The height of the truss bars is higher than the height of the edge angle steel, and the upper ends of the truss bars are located outside the cavity structure. The truss bars are parallel to the prestressed steel bars and are evenly distributed.

[0044] Furthermore, the wall components are placed horizontally on the base surface for concrete pouring and application of prestressed steel bars.

[0045] By setting truss reinforcement in the cavity structure, the structural stability and shear resistance of the wall components can be significantly improved, especially when subjected to lateral forces.

[0046] The truss reinforcement is connected to the edge angle steel or edge channel steel, which can improve the wall component's ability to resist bending.

[0047] The height of the truss reinforcement is higher than the edge angle steel, which can ensure the uniform distribution of the internal structure of the wall components and improve the uniformity and stability of the overall structure.

[0048] The truss reinforcement is parallel to the prestressed steel bars and is evenly spaced, which can simplify the manufacturing process and improve production efficiency.

[0049] Standardized components and simplified manufacturing processes help reduce production costs while improving product quality.

[0050] After most of the work on prefabricated wall components is completed in the factory, only simple assembly is required on site, which greatly reduces on-site construction time and speeds up the construction progress.

[0051] Precise manufacturing in a factory environment ensures the dimensional accuracy and appearance quality of wall components, avoiding leakage and honeycombing that may occur during on-site pouring.

[0052] Through optimized internal structures, the performance of wall components in natural disasters such as earthquakes is enhanced, improving the safety of buildings.

[0053] The setting of truss reinforcement enhances the compressive capacity of wall components, making them more able to withstand heavy loads. The setting of truss reinforcement improves the durability of wall components and extends their service life.

[0054] The wall components are placed horizontally on the base surface for concrete pouring and prestressed steel bars, which simplifies the construction process and makes construction more convenient and quick.

[0055] In a second aspect, the present application provides an application of a wall component suitable for modular buildings in modular buildings. The modular building includes wall components, floors, and top beams. The wall components can be overlapped and are perpendicular to the parallel floors and top beams.

[0056] The wall components can be stacked together, which simplifies the construction process of modular buildings and makes on-site construction simpler and faster. After stacking, the supporting performance of the wall components is more solid.

[0057] The prefabricated design of wall components makes on-site construction simpler. Prefabricated components only need to be transported to the site for assembly, which greatly reduces on-site construction time and speeds up the construction progress.

[0058] (3) Beneficial effects

[0059] The beneficial effects of the present invention are as follows: the present invention is a wall component suitable for modular buildings. Since the wall component has completed the concrete pouring and installation of prestressed steel bars in the factory prefabrication stage, there is no need to build and dismantle the wall membrane during on-site construction, which greatly saves labor and time costs and speeds up the construction progress. The production environment of the prefabricated components is controllable, which can better control the pouring and curing conditions of the concrete, ensure the strength and density of the components, avoid problems such as leakage and honeycomb that may occur during on-site pouring, and improve the appearance quality and structural performance of the components. By applying prestress in the prefabrication stage, the bond between the prestressed steel bars and the concrete is enhanced, the tensile strength and rigidity of the wall components are improved, the generation of cracks in the decorative surface is effectively controlled, and the overall stability of the modular building is enhanced. The prefabricated design of the wall components makes on-site construction simpler. It is only necessary to transport the prefabricated components to the site for assembly, which reduces the complexity and uncertainty of on-site construction and reduces the difficulty of construction.

[0070] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is used as a reference. In this document, the longitudinal direction refers to the direction in which the prestressed steel bars 13 are applied, and the transverse direction refers to the direction perpendicular to the prestressed steel bars 13. In this application, fixed connections (except for the pouring of concrete 14), splicing, or lamination generally refer to welding. The horizontal plates parallel to the base plate 11 are fixed to the base plate 11, and the vertical plates are perpendicular to the base plate 11.

[0071] The beneficial effect of the present invention is that it significantly improves the structural performance and construction efficiency of the wall component 1 while reducing costs. First, by applying prestress, the cracking phenomenon of the concrete 14 when subjected to tension is effectively prevented, which solves the serious problem of cracking of traditional prefabricated wall panels, significantly improves the rigidity and crack resistance of the wall panel components, and enhances the stability and durability of the structure. Secondly, the use of finished angle steel or channel steel as a mold effectively reduces the mold opening cost of wall panels and prefabricated columns of different sizes, reduces mold waste and repeated investment, and thus reduces the overall production cost. In addition, the use of finished angle steel or channel steel as a mold simplifies the construction process, reduces the use and disassembly of on-site formwork, and speeds up the construction progress. In summary, the present invention not only improves the structural performance and construction efficiency of the wall component 1 by applying prestress and using finished angle steel or channel steel as a mold, but also reduces costs, improves construction quality, and enhances the safety and durability of the building.

[0072] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0073] Example 1:

[0074] Reference Figure 1 、 Figure 2 and Figure 3 A wall component 1 suitable for modular buildings, the wall component 1 includes a rectangular cavity structure with an upper end open, which is formed by a bottom plate 11 and four side plates 12 connected end to end. A plurality of prestressed steel bars 13 are supported on two opposite side plates 12. Concrete 14 is poured in the rectangular cavity structure, and the prestressed steel bars 13 pass through the concrete 14. The prestressed steel bars 13 are usually arranged longitudinally.

[0075] Reference Figure 1 and Figure 2 The wall component 1 is placed horizontally on the base surface for pouring concrete 14 and applying prestressed steel bars 13.

[0076] The base surface is a tensioning platform or a turning platform, which is convenient for applying prestress to the prestressed steel bars 13 .

[0077] Prestressed steel bars 13 are special steel bars that achieve a prestressed state by applying tensile stress to concrete 14 before it solidifies. This prestressing can offset or reduce the tensile stress generated by the concrete 14 structure during use, thereby improving the structure's load-bearing capacity and crack resistance.

[0078] When concrete components are subjected to external forces, they generate tensile and compressive stresses. In conventional reinforced concrete structures, the steel bars primarily resist tensile stress, while the concrete primarily bears compressive stress. In prestressed concrete structures, by pre-applying tensile stress to the steel bars, the concrete is placed in a compressive state, thereby improving the structure's crack resistance and load-bearing capacity.

[0079] The prestressed steel bar 13 is mainly made of stress-relieving spiral ribbed steel wire with a tensile strength standard of 1470MPa and diameters of ΦH4.8, ΦH7, and ΦH9.

[0080] Example 2

[0081] Reference Figure 3 This embodiment is a further refinement of embodiment 1. On the basis of embodiment 1, the wall component 1 is used as a prefabricated lightweight partition wall, and the lightweight partition wall structure is a construction structure.

[0082] In the first structural mode, the four side panels 12 are all edge angle steels 121, and the four side panels 12 include a first group of oppositely arranged edge angle steels 121 and a second group of oppositely arranged edge angle steels 121. The first group of edge angle steels 121 and the second group of edge angle steels 121 are perpendicular to each other.

[0083] The vertical and horizontal plates of each edge angle steel 121 are the same length and are both rectangular plates. The horizontal and vertical plates of the first group of relatively arranged edge angle steels 121 are the same length as the corresponding sides of the bottom plate 11. The horizontal and vertical plates of the second group of relatively arranged edge angle steels 121 are the same length and shorter than the length of the corresponding sides of the bottom plate 11. The sum of the length of the horizontal plates of the second group of edge angle steels 121 and the width of the horizontal plates of the two edge angle steels 121 in the first group is equal to the length of the bottom plate 11 corresponding to the second group of edge angle steels 121. The first group of relatively arranged edge angle steels 121 are arranged horizontally, and the first group of relatively arranged edge angle steels 121 are arranged vertically.

[0084] In addition, the wall component 1 further includes filling plates 17 , which are sequentially connected by plugging and longitudinally arranged in the cavity. The overall length of the filling plates 17 is the same as the overall length of the second set of edge angle steels 121 .

[0085] Connecting rods are provided at both ends of the filling plate 17 in the longitudinal direction. The connecting rods are located above the horizontal plates of the first group of relatively arranged edge angle steels 121 and are fixedly connected to the edge angle steels 121 through concrete 14. There is a gap between the left and right ends (transverse) of the filling plate 17 and the edge angle steels 121. Prestressed steel bars 13 are provided in this gap, and the gap is filled with concrete 14. The prestressed steel bars 13 are longitudinally inserted through the edge angle steels 121. In other words, a filling plate 17 is provided in the middle of the rectangular cavity, and edge angle steels 121 are provided on all sides. Concrete 14 is poured in the gap between the filling plate 17 and the vertical plates of the edge angle steels 121. The concrete 14 in the up and down directions connects the connecting rod of the filling plate 17 to the edge angle steel 121, and the concrete 14 in the left and right directions directly connects the filling plate 17 to the edge angle steel 121.

[0086] In this embodiment, the side angle steels 121 arranged transversely serve as ring beams, and the side angle steels 121 arranged longitudinally serve as structural columns.

[0087] Example 3

[0088] Reference Figure 3 This embodiment is a further refinement of embodiment 1. On the basis of embodiment 1, the wall component 1 is used as a prefabricated lightweight partition wall, and the lightweight partition wall structure is a second structure.

[0089] The four side panels 12 are composed of a set of oppositely positioned edge angle steels 121 and a set of oppositely positioned edge channel steels 122 perpendicularly connected to the ends of the edge angle steels 121. The edge channel steels 122 are C-shaped channel steels. The edge channel steels 122 include two vertical plates and a horizontal plate, with the horizontal plate positioned between the two vertical plates. In addition, two additional connecting plates can be provided, one at each end of the edge channel steels 122, perpendicular to the horizontal plate and connecting the two vertical plates to prevent uncured concrete 14 within the edge channel steels 122 from escaping. The edge channel steels 122 are arranged horizontally, while the edge angle steels 121 are arranged vertically.

[0090] The horizontal plate and vertical plate of the edge channel steel 122 are the same length as the corresponding sides of the bottom plate 11. The vertical plate of the edge channel steel 122 located in the cavity structure is provided with multiple positioning holes. The horizontal plate and vertical plate of the edge angle steel 121 are the same and shorter than the length of the corresponding sides of the bottom plate 11. The edge angle steel 121 is vertically connected to the edge channel steel 122.

[0091] The wall component 1 also includes a filling plate 17, which is connected to each other in sequence by plugging and arranged longitudinally in the cavity, and connecting rods are provided at both ends of the filling plate 17 in the longitudinal direction. The connecting rod is inserted into the positioning hole (pipe clamp method), and the connecting rod is located in the cavity of the edge channel steel 122, and the edge channel steel 122 is poured with concrete 14. There is a gap between the filling plate 17 and the edge angle steel 121 in the transverse direction, and the prestressed steel bar 13 is arranged in this gap, and the gap is filled with concrete 14. The prestressed steel bar 13 is longitudinally inserted into the edge channel steel 122. That is to say, the filling plate 17 is provided in the middle of the rectangular cavity, the edge angle steel 121 is provided longitudinally, and the edge channel steel 122 is provided transversely. Concrete 14 is poured in the gap between the filling plate 17 and the vertical plate of the edge angle steel 121, and concrete 14 is poured in the edge channel steel 122. Concrete 14 is poured into the edge channel steel 122 to connect the connecting rod of the filling plate 17 with the edge channel steel 122 , and the concrete 14 in the left and right directions directly connects the filling plate 17 with the edge angle steel 121 .

[0092] In this embodiment, the transversely arranged edge channel steels 122 serve as ring beams, and the longitudinally arranged edge angle steels 121 serve as structural columns.

[0093] Example 4

[0094] Reference Figure 1 and Figure 2 This embodiment is a further refinement of embodiment 1. On the basis of embodiment 1, the wall component 1 is used as a non-prefabricated lightweight partition wall, and the lightweight partition wall structure is a three-structure structure.

[0095] Reference Figure 4 The four side panels 12 are all edge angle steels 121. The horizontal plate of the edge angle steel 121 is an isosceles trapezoidal plate. The two adjacent horizontal plates are spliced ​​together by the bevel at the end of the isosceles trapezoidal plate. The inner angle of the isosceles trapezoidal plate is between 40-50 degrees, preferably 45 degrees. The longer side of the isosceles trapezoid is perpendicularly connected to the vertical plate of the edge angle steel 121, and the longer side of the isosceles trapezoidal plate is the same length as the vertical plate of the edge angle steel 121. The two perpendicular edge angle steels 121 are connected with the vertical plates and the horizontal plates, that is, the bevel at the end of one isosceles trapezoidal plate (the waist of the isosceles trapezoid) is spliced ​​with the bevel at the end of the other adjacent isosceles trapezoidal plate (the waist of the isosceles trapezoid).

[0096] Reference Figure 5 In addition, in this embodiment, the wall member 1 also includes a plurality of ribs 15 and ribs 16. The ribs 15 and ribs 16 are disposed within the cavity structure. The ribs 16 can also be disposed outside the cavity structure, i.e., on the other side of the base plate 11. The ribs 15 are perpendicular to the horizontal and vertical plates of the edge angle steel 121. By slightly increasing the length of the ribs 15, the ribs 15 can be perpendicular to the base plate 11, thereby enhancing the connectivity between the side panels 12 and the base plate 11. The ribs 16 are the same length as the base plate 11.

[0097] In addition, the wall component 1 also includes a truss bar 19, the lower end of the truss bar 19 is located in the cavity structure and abuts against the edge angle steel 121 or the edge channel steel 122. The height of the truss bar 19 is higher than the height of the edge angle steel 121, and the upper end of the truss bar 19 is located outside the cavity structure; the truss bar 19 is parallel to the prestressed steel bars 13 and is evenly distributed at intervals.

[0100] The four side panels 12 are all edge angle steels 121, and the horizontal plates of the edge angle steels 121 are rectangular plates. The horizontal plates of the first group of relatively arranged edge angle steels 121 are shorter than the vertical plates, and the horizontal plates of the second group of relatively arranged edge angle steels 121 are the same as the vertical plates.

[0101] Reference Figure 7 In the first set of oppositely positioned edge angles 121, the vertical plates are the same length as the corresponding sides of the bottom plate 11, and both ends of the horizontal plates are spaced apart from the corresponding ends of the vertical plates. This distance forms the clearance area 18 formed at the ends. In the second set of oppositely positioned edge angles 121, the vertical and horizontal plates are the same length as the corresponding sides of the bottom plate 11. In two adjacent edge angles 121, the end of the horizontal plate of one edge angle 121 is located within the clearance area 18 of the other edge angle 121 and is aligned with the horizontal plate and vertical plate of the edge angle 121 where the clearance area 18 is located.

[0102] In addition, in this embodiment, the wall member 1 also includes a plurality of ribs 15 and ribs 16. These ribs 15 and ribs 16 are disposed within the cavity structure. Ribs 16 can also be disposed outside the cavity structure, i.e., on the other side of the base plate 11. Ribs 15 are perpendicular to the horizontal and vertical plates of the edge angle steel 121. By slightly increasing the length of ribs 15, they can be perpendicular to the base plate 11, thereby enhancing the connectivity between the side panels 12 and the base plate 11. Ribs 16 are the same length as the base plate 11.

[0103] In addition, the wall component 1 also includes a truss bar 19, the lower end of the truss bar 19 is located in the cavity structure and abuts against the edge angle steel 121 or the edge channel steel 122. The height of the truss bar 19 is higher than the height of the edge angle steel 121, and the upper end of the truss bar 19 is located outside the cavity structure; the truss bar 19 is parallel to the prestressed steel bars 13 and is evenly distributed at intervals.

The wall components 1 can be overlapped (fixed and welded in the thickness direction and the length direction), and the wall component 1 is perpendicular to the parallel floors and top beams.

[0107] The wall components 1 include prefabricated composite walls, prefabricated beam molds, prefabricated wall molds, and prefabricated lightweight partition walls. Different cavity components can be stacked on each other as needed.

[0108] Example 7

[0109] A method for preparing a wall component 1 suitable for modular building comprises the following steps:

[0110] Step 1: Fix the bottom plate 11 and the side plates 12 around to form a closed cavity structure; reserve multiple steel bar holes on the side plates 12 for the prestressed steel bars 13 to pass through; and set ribs 15 on the side plates 12 as needed.

[0111] Step 2: Insert the prestressed steel bars 13 between the parallel and opposite side panels 12 along the longitudinal direction of the wall component 1 in the cavity structure; apply prestress to the prestressed steel bars 13 and use the pre-tensioning method to ensure effective transmission of the prestress; the formula is

[0112] σcon=0.6fptk, where σcon is the tension control stress and fptk is the standard value of the tensile strength of the prestressed steel bar 13;

[0113] Step 3: After the prestressed steel bars 13 are tensioned, concrete 14 is poured into the cavity structure. The strength grade of the concrete 14 needs to be based on the actual engineering design requirements. After pouring, the concrete 14 is cured to ensure that its strength gradually increases.

[0114] Step 4: When the strength of the concrete 14 reaches at least 75% of the design strength, the prestressed steel bars 13 are tensioned and cut to the corresponding positions according to the design requirements.

[0115] Step 5: After the prestressing is released, the wall component 1 is further cured until the concrete 14 is completely hardened.

[0116] Step 6: Assemble the prefabricated wall components 1 into a modular building unit through dry connection methods such as welding.
