Abstract

To provide a building structure of S3RC steel reinforced construction that can solve a problem caused by RC structure, SC structure, and SRC structure.SOLUTION: There is provided a building structure of S3RC steel reinforced construction comprising a steel frame, at least one steel shell layer, multiple rebars, and a concrete body. The steel shell layer is mounted on the steel frame, and the rebars are connected to the steel frame, and located at one side of the steel shell layer. The concrete body is mounted at one side of the steel shell layer and covers the rebars. Covering the concrete body and the rebars using the steel shell layer and the steel frame improves tensile intensity of the concrete body from the outside and enhances earthquake resistance. Even if the concrete body is shattered by the earthquake, the steel shell layer covers the broken pieces, scattering of the broken pieces is prevented and collapse of the overall structure is avoided. Furthermore, the steel shell layer protects the concrete body from being affected by the atmosphere and moisture, and expansion of the concrete body is prevented and weathering can be avoided, and thus, good structure of the concrete body is maintained.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to architectural structures, and more particularly to an integrated, continuous structure in which the concrete of walls, columns, beams, and floor plates and the internal steel materials are covered with steel plates and steel frames. [Background technology]

[0002] Modern building structures generally use reinforced concrete (RC) as the main structure, and architectural structures have evolved from primarily RC structures to steel-reinforced concrete (SRC) structures, which combine steel construction (SC) as the main support. This is because high-rise buildings made of purely steel structures are not suitable for residential buildings, as the high plasticity of steel causes large horizontal displacements on the upper floors when subjected to horizontal wind or seismic forces, making people in rooms on the upper floors uncomfortable.

[0003] In traditional SRC construction, the center of the beams and columns is supported by steel frames, and the outside is covered with 15 to 20 cm of concrete. Thick main reinforcement bars and hoop reinforcement are contained within the concrete, and the rebar and steel frame work together. This construction requires formwork, assembling and processing rebar, and applying cement.

[0004] Taiwan Utility Model No. M358176 proposes a reinforced concrete wall, the construction of which involves assembling lightweight steel beams, laying wire mesh on the outside, placing rebar on the inside, and then pouring concrete. While this construction method can be completed in a relatively short time, wire mesh walls are not very watertight, so waterproofing is required when used as an exterior wall. It is also recommended for other walls that do not require load-bearing or shear-resistance applications. Furthermore, in this utility model, the construction of the wire mesh wall involves assembling multiple pre-formed steel frames and double wire mesh, pouring concrete, and after the concrete has cured, dried, and hardened, applying a surface treatment to the double wire mesh by hand painting or mechanical spraying. Finally, the construction of the wire mesh wall is completed.

[0005] Furthermore, traditional RC, SC, and SRC structures are like bones wrapped in flesh, with the concrete and rebar exposed to the air and no external protection, resulting in low tensile strength, susceptibility to structural deterioration, and reduced seismic resistance. When an earthquake strikes, the concrete can spall off and the structure can collapse instantly. Furthermore, because the concrete and rebar in traditional RC, SC, and SRC structures are exposed to the air, harmful environmental factors can cause the concrete and rebar to undergo electrochemical reactions, expanding their volume. Alternatively, environmental humidity, moisture, or seawater erosion can cause the concrete to undergo oxidation-reduction reactions, weakening the structure.

[0006] From the above, it can be seen that there is certainly room for improvement in the conventional RC, SC, and SRC structures. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Taiwan Utility Model Registration No. TW M358176 Summary of the Invention [Problem to be solved by the invention]

[0008] The main object of the present invention is to provide an S3RC steel frame building structure that can solve the problems of RC, SC and SRC structures mentioned above. [Means for solving the problem]

[0009] In order to achieve the above object, the S3RC steel frame building structure of the present invention is as follows: Steel frame and At least one steel shell layer installed on the steel frame, each of which includes a plurality of outer steel decks installed parallel to each other; a plurality of reinforcing bars connected to the steel frame and located on one side of the at least one steel shell layer; a concrete body installed on one side of the at least one steel shell layer and covering the reinforcing steel; Each of said outer steel decks is One main body portion that is a rectangular body; two connection portions respectively connected to two opposing edges of the main body and extending outward from the two opposing edges, each of the connection portions protruding toward one side of the at least one steel shell layer; The two connection portions of any two adjacent outer steel decks are connected to each other.

[0010] In order to achieve the above object, another S3RC steel frame building structure of the present invention is as follows: At least one steel shell layer is attached to the surface of a reinforced concrete (RC) structure to cover the reinforced concrete structure; The at least one steel shell layer includes a plurality of outer steel decks that are installed parallel to each other, and each of the outer steel decks includes: One main body portion that is a rectangular body; two connection portions respectively connected to two opposing edges of the main body and extending outward from the two opposing edges, each of the connection portions protruding toward one side of the at least one steel shell layer; The two connection portions of any two adjacent outer steel decks are connected to each other.

[0011] In order to achieve the above object, another S3RC steel frame building structure of the present invention is as follows: At least one steel shell layer is attached to the surface of a steel reinforced concrete (SRC) structure to cover the SRC structure; The at least one steel shell layer includes a plurality of outer steel decks that are installed parallel to each other, and each of the outer steel decks includes: One main body portion that is a rectangular body; two connection portions respectively connected to two opposing edges of the main body and extending outward from the two opposing edges, each of the connection portions protruding toward one side of the at least one steel shell layer; The two connection portions of any two adjacent outer steel decks are connected to each other.

[0012] In order to achieve the above object, another S3RC steel frame building structure of the present invention is as follows: The present invention has at least one steel shell layer that is attached to the surface of a steel construction (SC) to cover the steel construction.

[0013] The advantage of this invention is that by covering the concrete body and rebar with a steel shell and / or steel frame, the tensile strength of the concrete body is improved from the outside, enhancing earthquake resistance. With this structure, even if the concrete body shatters during an earthquake, the steel shell can contain the fragments, preventing them from scattering and preventing the collapse of the entire structure. Furthermore, the steel shell protects the concrete body from the effects of air and moisture, preventing expansion and weathering, thereby maintaining the concrete body's structural integrity. In the S3RC structure of this invention, the columns, beams, walls, and floors are all constructed with at least one steel plate and steel frame. The walls and floors provide the building's tensile strength, disperse external forces, and reduce deformation. Therefore, during an earthquake, horizontal forces caused by the earthquake can be offset, resulting in smaller shaking amplitudes and fewer changes in comfort, reducing the likelihood of cracks in the walls.

[0015] First, as shown in Figures 1, 5, and 7, the present invention is an S3RC steel-framed building structure, which includes at least a steel shell layer 10, a steel frame 20, a plurality of reinforcing bars 30, and a concrete body 50, and the steel frame 20 encases a reinforced concrete structure, the outer layer of which is encased by the steel shell layer 10. The overall structure is divided into an inner layer RC structure entirely encased by the steel shell layer 10, and an outer layer SC (Steel Construction, SC) structure, and since it has three layers of steel (Steel*3) and reinforced concrete (RC) in cross section, the present invention is called an S3RC steel-framed building structure.

[0016] In addition, as shown in Figures 11 to 13, a method of covering structures such as RC, SRC, and SC with a steel shell layer 10 can also be adopted, thereby providing these types of architectural structures with the effects of structural reinforcement, earthquake prevention, and protection.

[0017] As shown in Figures 1 and 2, the reinforcing bars 30 are connected to the steel frame 20 and are located on one side of the steel shell layer 10. The steel shell layer 10 includes a plurality of outer steel decks 11 and a plurality of fixing members 12. However, the configuration of the steel shell layer 10 is not limited to this and may be made of C-shaped steel or metal steel plate (meaning various types of metal support plate, for example, galvanized steel plate).

[0018] Furthermore, the outer steel decks 11 are arranged parallel to each other, and each outer steel deck 11 has one main body 110 and two connecting parts 111. The main body 110 is a rectangular plate, and the two connecting parts 111 are connected to two opposing edges of the main body 110, respectively, and extend along the opposing edges, and each connecting part 111 protrudes toward one side of the steel shell layer 10. Note that the two connecting parts 111 of any two adjacent outer steel decks 11 are connected to each other, but the shape of the connecting parts 111 is not limited to this.

[0019] Specifically, in this embodiment, the two connection portions 111 of each exterior steel deck 11 include a first connection portion 112 and a second connection portion 113, and the first connection portion 112 has a connection groove 1121 formed so as to curve in a direction away from the second connection portion 113, and the second connection portion 113 curves toward the first connection portion 112. In this configuration, when two adjacent exterior steel decks 11 are connected to each other, the second connection portion 113 of one exterior steel deck 11 is located in the connection groove 1121 of the first connection portion 112 of the other exterior steel deck 11, but this is not limited to this.

[0020] In this embodiment, a plurality of fixing members 12 are provided, and each fixing member 12 is installed by penetrating the connection portions 111 of any two adjacent outer steel decks 11. Specifically, the fixing members 12 are studs that penetrate and fit into the first and second connection portions 112 and 113 that are connected to each other, thereby fixing the relative positions of the two outer steel decks 11. Note that, with this configuration, the steel shell layer 10 can be formed by connecting multiple outer steel decks 11 in series, but this is not limited to this. In other embodiments, the fixing members 12 may not be provided, and the steel shell layer 10 may be formed by directly connecting multiple outer steel decks 11 by welding, for example.

[0021] A plurality of reinforcing bars 30 are located on one side of the steel shell layer 10 , and a concrete body 50 is also installed on one side of the steel shell layer 10 to cover the reinforcing bars 30 .

[0022] The S3RC steel frame building structure of the present invention can be used for the construction of wall structures, column structures, and floor structures. Each structure will be described in detail below.

[0023] As shown in Figures 1 to 3, in the wall structure of the present invention, a steel frame 20 includes steel beams 21 and steel columns 22, which are interconnected, with the steel columns 22 extending vertically and the steel beams 21 extending horizontally. There are two steel shell layers 10, which are spaced apart, positioned opposite each other, and connected to the steel beams 21 and steel columns 22. A plurality of reinforcing bars 30 are connected crosswise, and the two steel shell layers 10 are arranged between baseline C-shaped steel beams 35. The spacing between the two steel shell layers 10 can be adjusted as needed.

[0024] When constructing the wall structure of the present invention, first, the steel columns 22 and steel beams 21 of the steel frame 20 are installed, and two baseline C-shaped steels 35 are placed on the steel beams 21 at a distance from each other using laser positioning. Two steel shell layers 10 are then connected to the two baseline C-shaped steels 35 and placed between the two baseline C-shaped steels 35. It is preferable to connect the steel shell layers 10 and the baseline C-shaped steels 35 by welding.

[0025] Next, multiple horizontal reinforcing bars 31 are installed on the surface of each steel shell layer 10 facing the other steel shell layer 10, and multiple vertical reinforcing bars 32 are installed on top of the horizontal reinforcing bars 31. The horizontal reinforcing bars 31 and vertical reinforcing bars 32 installed in each steel shell layer 10 form an outer reinforcing bar mesh 39. The horizontal reinforcing bars 31 and the steel shell layer 10 are preferably connected by welding. In this connection, the horizontal reinforcing bars 31 and the vertical reinforcing bars 32 are preferably tied and secured together before being connected by welding. However, this is not limited to this. For example, in another embodiment, the horizontal reinforcing bars 31 can be replaced with stainless steel circulation pipes, which provide a water circulation path to regulate the temperature of the wall structure. In this embodiment, the spacing between two adjacent horizontal reinforcing bars 31 is approximately 50 cm, and the spacing between two adjacent vertical reinforcing bars 32 is approximately 15 cm. However, this spacing is not limited to this and can be adjusted as needed.

[0026] The center line between the two steel shell layers 10 is positioned using a laser, and the inner reinforcing steel mesh 33 is installed. In this embodiment, the inner reinforcing steel mesh 33 can be, but is not limited to, a bamboo-shaped reinforcing steel mesh. Each mesh of the inner reinforcing steel mesh 33 is approximately 10 cm long and approximately 10 cm wide, but this spacing can be adjusted as needed. Two outer reinforcing steel meshes 39 are installed at a distance from the inner reinforcing steel mesh 33 and are located between the two steel shell layers 10. The spacing between the outer reinforcing steel mesh 39 and the inner reinforcing steel mesh 33 can also be adjusted as needed. Next, water, electricity, and fire piping are installed between the inner reinforcing steel mesh 33 and the horizontal reinforcing steel bars 31. Box holes for water, electricity, and fire hoses and window holes are pre-drilled in the steel shell layer 10. Then, multiple width-fixing reinforcing steel bars 34 are installed to fix the width between the two steel shell layers 10. In this embodiment, the interval between two adjacent width-fixing rebars 34 is approximately 20 cm, but this is not limited to this and the interval can be adjusted as needed. Also, the installation process of the width-fixing rebars 34 is a conventional technique in this technical field, so a detailed description will not be given here.

[0027] Next, as shown in Figures 1, 4 and 9, in the column structure of the present invention, the steel shell layer 10 is installed along the vertical direction and is formed to surround the column installation space 40, and the steel column 22 of the steel frame 20 is installed and placed in this column installation space 40.

[0028] In addition, in this embodiment, the steel shell layer 10 of the column structure is preferably formed by a plurality of reinforcing steel decks 11A that are interconnected and surround the steel columns 22. Each reinforcing steel deck 11A has a structure similar to that of the outer steel deck 11, including a main body 110A and two connecting portions 111A. The two connecting portions 111A are located on two opposing edges of the main body 110A, and the reinforcing steel decks 11A are connected to each other via the connecting portions 111A. The main difference between the reinforcing steel decks 11A and the outer steel deck 11 is that the reinforcing steel deck 11A is thicker than the outer steel deck 11, resulting in higher strength. Specifically, in this embodiment, the thickness of the outer steel deck 11 is approximately 2.8 mm, and the thickness of the reinforcing steel deck 11A is approximately 3.2 mm. However, the thicknesses of the outer steel deck 11 and the reinforcing steel deck 11A can be adjusted as needed.

[0029] When assembling the column structure of the present invention, first, the two sides of the steel column 22 are set based on the baseline of two adjacent wall structures, specifically, based on the extension lines of the horizontal reinforcing bars 31 on the steel shell layer 10 in the outer layer of the two adjacent wall structures. Then, the horizontal reinforcing bars 31 are connected to the steel column 22, and it is preferable that the horizontal reinforcing bars 31 and the steel column 22 are connected by welding. Furthermore, a plurality of reinforcing steel decks 11A are connected to each other to form the steel shell layer 10, and the steel column 22 is surrounded by the plurality of reinforcing steel decks 11A. As a result, the steel column 22 is located in the column installation space 40 surrounded by the steel shell layer 10, and a drainage system and water and electricity piping can also be installed in the column installation space 40. In this embodiment, the steel shell layers 10 are welded to the steel columns 22. Specifically, the outer steel shell layers 10 of the two adjacent wall structures are welded to the steel columns 22, thereby improving the strength of the structure. As a result, the steel shell layers 10 of the wall and the outer steel deck 11 of the column form a continuous structure, and the concrete body can be poured all at once in the space enclosed between them, so that the concrete body forms a continuous, integrated structure between the wall structure and the column structure.

[0030] The column structure of this embodiment may further include a steel clamping ring 60 located outside the steel shell layer 10 and surrounding the steel shell layer 10. Specifically, the steel clamping ring 60 in this embodiment is made by bending a C-shaped steel and is welded to the outside of the steel shell layer 10 to clamp the steel shell layer 10 of the column structure and increase the strength of the structure. However, this is not limited to this. In other embodiments, the steel clamping ring 60 may not be provided, or the steel clamping ring 60 may be connected to the outer layers of the steel shell layers 10 of two adjacent wall structures by welding.

[0031] The outer steel shell layer 10 and the reinforced steel deck 11A can be made of galvanized steel or stainless steel to improve water resistance. Furthermore, the reinforced steel decks 11A and the connecting portions 111A can be welded with additional rebars to increase strength. Alternatively, additional rebars can be added to the reinforced steel deck 11A together with the steel shell layer 10 and used through-hole reflow soldering to strengthen the connection between the wall structure and the column structure. Alternatively, additional rebars can be added to the reinforced steel deck 11A together with the rebars 30 and used through-hole reflow soldering to connect them. However, the construction method is not limited to these. Furthermore, the steel clamping rings 60 and the reinforced steel deck 11A can be connected by welding to strengthen earthquake resistance. These can be installed at the bottom of the building as needed, and the number can be adjusted as needed.

[0032] Next, the floor structure of the present invention will be further described with reference to Figures 5 to 8. In the floor structure of the present invention, a steel frame 20 includes steel beams 21, and at least one steel shell layer 10 is installed horizontally and connected to the steel beams 21, with the steel shell layer 10 installed flat. A plurality of reinforcing bars 30 are connected in a cross shape to form a plurality of reinforcing bar meshes. The reinforcing bar meshes are arranged parallel to each other and installed on the steel shell layer 10 at intervals.

[0033] As shown in FIGS. 5 to 8, specifically, the steel beam 21 has a top and bottom that face each other. Depending on the relative positions of the concrete body 50 and the steel beam 21, the present invention may have different types of floor panel structures. For example, the present invention may have a built-in type floor panel structure in which the concrete body 50 and the steel beam 21 are at approximately the same height, or a top-mounted type floor panel structure in which the concrete body 50 is located above the steel beam 21A. When applied to a built-in type floor panel structure, as shown in FIGS. 5 to 6, the steel shell layer 10 is located at the bottom 2111 of the main beam 211 of the steel beam 21, and multiple reinforcing bar meshes are connected to the steel beam 21A. When applied to a top-mounted type floor panel structure, as shown in FIGS. 7 to 8, the steel shell layer 10 is connected to the top 2121A of the sub-beam 212A of the steel beam 21A.

[0034] The construction of the floorboard structure of the present invention can also be carried out after the above-mentioned wall structure and column structure have been completed.

[0035] 5 and 6, in the built-in floor panel structure of the present invention, the steel beam 21 includes a plurality of main girders 211 and a plurality of sub-girders 212, and both ends of the sub-girders 212 are connected to the portions located on the center lines of the main girders 211. The main girders 211 and the sub-girders 212 are preferably connected by welding, and furthermore, it is also possible to use reinforcing plates and perform all-around welding, but this is not limitative.

[0036] After securing the installation space for the stairway passage, holes 213 are drilled along the center lines of the sub-girders 212. The inner diameter of each hole 213 is preferably between 6 and 10 cm. In this embodiment, the inner diameter of the holes 213 is approximately 8 cm, but is not limited to this. The reinforcing bars 30 are connected to the main girder 211 and the sub-girders 212 so as to cross each other along their extension, thereby forming an upper layer reinforcing bar mesh 36 and a lower layer reinforcing bar mesh 37. The upper layer reinforcing bar mesh 36 is installed along the center line of the sub-girders 212, and the reinforcing bars extending along the longitudinal direction of the main girder 211 in the upper layer reinforcing bar mesh 36 pass through the holes 213 along the center lines of the sub-girders 212 and are connected to the sub-girders 212 by welding. In this embodiment, the length and width of each mesh in the upper layer reinforcing bar mesh 36 and the lower layer reinforcing bar mesh 37 are approximately 10 cm, but are not limited to this.

[0037] The lower layer reinforcing bar mesh 37 is connected to the sub-beam bottoms 2121 of each sub-girder 212 by welding, and the steel shell layer 10 is installed below it. In this embodiment, the steel shell layer 10 is laid flat and connected to the lower layer reinforcing bar mesh 37 by welding, and each outer steel deck 11 of the steel shell layer 10 is installed in a direction parallel to the main girder 211, but this is not limited to this. In addition, a plurality of processed reinforcing bars 38 are connected between the upper layer reinforcing bar mesh 36 and the lower layer reinforcing bar mesh 37 by bundling or welding, thereby connecting the upper layer reinforcing bar mesh 36 and the lower layer reinforcing bar mesh 37, but this is not limited to this.

[0038] 7 and 8, in the top-mounted floor panel structure of the present invention, the steel beam 21A includes a plurality of main girders 211A and a plurality of sub-girders 212A, and the sub-girders 212A are connected to the main girder tops 2111A of the main girder 211A, and the sub-girders 212A are arranged at intervals from each other. Specifically, in this embodiment, a reinforcing plate is used between the main girder 211A and the sub-girders 212A, and they are fastened with screws and welded all around, but this is not limited to this.

[0039] After securing the installation space for the stairway passage, the steel shell layer 10 is installed on the tops 2121A of the sub-girders 212A, and at this time, each outer steel deck 11 in the steel shell layer 10 is arranged in a direction parallel to the main girder 211A.

[0040] In the upper-mounted floor panels, many reinforcing bars 30A are connected to each other in a crosswise manner along the extension direction of the girders 211A and the sub-girders 212A, thereby forming an upper layer reinforcing bar mesh 36A and a lower layer reinforcing bar mesh 37A. In this embodiment, the length and width of each mesh of the upper layer reinforcing bar mesh 36A and the lower layer reinforcing bar mesh 37A are approximately 10 cm, but are not limited to this. The lower layer reinforcing bar mesh 37A is welded and fixed above the steel shell layer 10, and sufficient vertical space is provided for the installation of the upper layer reinforcing bar mesh 36A. In this embodiment, the distance between the upper layer reinforcing bar mesh 36A and the lower layer reinforcing bar mesh 37A is approximately 10 cm, but is not limited to this, and the distance between the upper layer reinforcing bar mesh 36A and the lower layer reinforcing bar mesh 37A can be adjusted according to actual needs. Specifically, the reinforcing bars 38 in the processed shape are welded and bound above the lower layer reinforcing bar mesh 37A, and then the upper layer reinforcing bar mesh 36A is installed above the reinforcing bars 38 in the processed shape, but this is not limitative.

[0041] After the installation of the steel shell layer 10, steel frame 20, and reinforcing bars 30 in the aforementioned column structure, wall structure, and floor plate structure is completed, concrete bodies 50 are poured into the wall structures, column structures, and floor plate structures of the entire building. In the case of an upper-mounted floor plate structure, the concrete body 50 is poured upward from the steel shell layer 10 to cover the upper layer reinforcing bar mesh 36A, and then poured upward to a thickness of approximately 15 cm, but this is not limited to this.

[0042] Before pouring the concrete body 50, building components such as box frames for water supply, electricity, and firefighting equipment, window frames, door frames, and passage frames may be installed first, but the order in which the concrete body 50 is poured is not limited to this. The concrete body 50 may be poured into the column structure, wall structure, and floor structure all at once after the steel shell layer 10, steel frame 20, and reinforcing bars 30 have been installed in the column structure, wall structure, and floor structure. Furthermore, another steel shell layer 10 may be installed on top of the concrete body 50 of the floor structure, and other construction layers may also be used, particularly in the rooftop area, thereby improving the overall strength of the S3RC steel-framed building structure.

[0043] Once the first floor is installed, a baseline C-shaped steel beam 35 is attached 2-3 cm above the concrete pouring surface of the floor structure to accurately position the next floor in terms of horizontal and elevation. Next, the steel columns 22 and steel beams 21 of the steel frame 20 are welded together, and the installation of the column structure, wall structure, and floor structure is repeated. Specifically, the steel frame 20 can be installed up to a height of approximately the second to fourth floor. Then, the column structure, wall structure, and floor structure are completed in stages, and concrete is poured. However, this is not limited to this; the second to fourth floors can also be installed as a single unit. Furthermore, as shown in Figure 10, C-shaped steel beams 70 can be installed horizontally between floors to reinforce the covering. Specifically, the C-shaped steel beams 70 are installed on the outside of the steel beams 21. The C-shaped steel 70 can also be used as the base for other steel deck structures such as roofs and steel shutters, but is not limited to this. It is also possible to install the C-shaped steel 70 on the inner steel shell layer without covering the steel beams 21 with the C-shaped steel 70.

[0044] The S3RC steel-framed building structure of the present invention is a continuous structure consisting of wall structures, column structures, and floor structures, with the steel shell layer 10 covering the steel frame 20, concrete body 50, and reinforcing bars 30. The S3 in S3RC refers to the three-layer structure of "shell-beam-shell" in floor structures and wall structures, "hoop-shell-frame" in column structures, and "wire-shell / shell-wire" in wall structures. Utilizing the above-mentioned structure, the present invention employs an S3RC earthquake-resistant building with a wall structure, column structure, and floor structure made up of three layers of steel: steel shell layer-steel frame-steel shell layer.

[0045] The S3RC steel plate steel frame building structure of the present invention has the following advantages:

[0046] Advantage 1: The method uses the steel shell layer 10 as a formwork and directly pours the concrete body 50 without using formwork. Also, since formwork is mainly made of wood, the use of the steel shell layer reduces tree felling and contributes to environmental protection. Furthermore, the finishing process can also be reduced during the work process, which significantly reduces construction waste, contributes to environmental protection, shortens construction time, and saves costs.

[0047] Advantage 2: After the concrete body 50 hardens and solidifies, the steel shell layer 10 acts like an exoskeleton or steel armor, isolating moisture and the atmosphere from the outside and preventing weathering caused by chemical reactions of the hardened concrete body 50. Furthermore, when the concrete body 50 is covered with the steel shell layer 10, it becomes impermeable to water and air, increasing its compressive strength and extending the deterioration time several times. The steel shell layer 10 can also be waterproofed. Furthermore, because the steel shell layer 10 has excellent ductility and tensile strength, it can support the concrete body 50, which is strong in compression but weak in bending. Even if the concrete body 50 is destroyed by an earthquake or other event, the steel shell layer 10 and columns can contain the concrete body 50 fragments, maintaining bearing capacity and preventing collapse through a bridge-like stacked structure.

[0048] Advantage 3: In a wall structure covered with a steel shell layer 10, the horizontal reinforcing bars 31 connected to the steel shell layer 10 can be replaced with pipes (e.g., galvanized steel pipes or stainless steel pipes), which can be connected to a circulation pump to transport cold or hot water. The steel shell layer 10 has excellent thermal conductivity, which can be used to adjust the wall temperature and further the indoor temperature, thereby reducing the use of central air conditioning and contributing to environmental protection.

[0049] Advantage 4: Because the steel shell layer 10 is used for the wall structure, stainless steel mirror plates, hairline plates, color boards, etched plates, or decorative plates can be attached by welding or nailing to the wall structure in locations such as bathrooms, kitchens, and toilets, so there is no need to worry about tiles peeling off due to expansion, and small items can be fixed by attaching magnets directly to the wall structure.

[0050] Advantage 5: This invention combines the advantages of conventional SC and SRC steel frame structures. Because steel materials have excellent rigidity and toughness, they are applicable to mid-rise buildings. This overcomes the drawback of large column and beam cross sections in RC structures, which waste space. Furthermore, the use of steel materials with higher toughness compared to RC structures allows for a variety of structural changes in the building's exterior. Furthermore, because the steel frame 20 and steel shell layer 10 are precast in a factory and then transported to the site and assembled, construction work can be carried out quickly, leading to a shorter construction period. Furthermore, because the wall formed by the steel shell layer 10 is flat in both the horizontal and vertical directions, construction standards can be easily met.
