Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a composite wall and a method for manufacturing the same. Background Art

[0002] Whether in residential construction or road and bridge construction, retaining walls are essential structures. They serve as the first line of defense against external shocks or earthquakes. They withstand horizontal and vertical loads caused by wind and earthquakes, preventing shear failure in buildings and structures. They are typically constructed of reinforced concrete.

[0003] In traditional construction, the vast majority of work requires on-site tying of steel cages and pouring concrete. The resulting retaining wall structure is relatively stable and appropriately sized, but long construction periods, large material storage areas, and a shortage of construction workers have become barriers to the advancement of the construction industry. While prefabricated buildings offer significant construction advantages, they require a variety of standardized molds for different building structures, resulting in limited versatility in retaining walls. Furthermore, the prefabricated walls are heavy and difficult to transport. Furthermore, the assembly process requires large machinery, making positioning, reinforcement, and adjusting the verticality of the retaining walls complex and labor-intensive. This heavy workload leads to poor construction schedule control, low efficiency, and poor construction precision, resulting in high costs. Furthermore, composite structure walls suffer from serious problems such as water leakage, resulting in low user satisfaction and hindering the development of prefabricated structures. Furthermore, existing building walls have poor impact toughness. When used for road and bridge retaining walls, vehicles collide with them in some traffic accidents, exerting significant impact forces on the vehicles. Moreover, due to the large impact force, the building wall itself will also be severely damaged, which is not conducive to the later repair of the building wall. Summary of the Invention

[0040] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0041] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a prefabricated wall structure provided by related technologies. To facilitate assembly, my country began promoting the use of low-rise cold-formed, thin-walled steel enclosure walls in 2000. Cold-formed, thin-walled steel composite walls are commonly used as building enclosures. Cold-formed, thin-walled steel structural systems offer a high degree of standardization, excellent seismic performance, and environmental friendliness, but are primarily used in residential buildings of three stories or fewer.

[0042] The load-bearing capacity of the cold-bent thin-walled steel building system in the prior art is lower than that of general reinforced concrete structures and ordinary steel structures. The number of floors of a residence is greatly limited, and only low-rise buildings can be built. Most areas in my country are located in areas with severe earthquake disasters. The cold-bent thin-walled steel building system in the existing technology has the following problems in terms of earthquake resistance: (a) As the structure height increases, the P-Δ effect of the earthquake load will be aggravated. The lateral stiffness of the composite wall in the cold-bent thin-walled steel building system in the existing technology is low, resulting in low lateral resistance and bearing capacity of the cold-bent thin-walled steel building system; (b) From the perspective of ductility, the energy consumption capacity of the composite wall in the cold-bent thin-walled steel building system in the existing technology is lower than that of the frame structure and the enclosing wall structure; (c) From the perspective of multiple seismic fortifications, the cold-bent thin-walled steel building system in the existing technology has only one seismic fortification. Once it is destroyed, the subsequent continuous earthquakes will cause the building to collapse; (d) From the perspective of impact resistance, the impact resistance of the composite wall in the cold-bent thin-walled steel building system in the existing technology is poor, and the safety factor during use is low.

[0043] In the examples of this application, please refer to Figure 2 , Figure 2 This is a structural diagram of a composite wall provided by an embodiment of the present application. The composite wall 000 may include: a first maintenance layer 100, a structural layer 200 and a second maintenance layer 300. In order to more clearly see the structure of the composite wall 000, please refer to Figure 3 , Figure 3 yes Figure 2 An exploded view of a composite wall is shown, showing a first connecting member 400 and a second connecting member 500 .

[0044] The first maintenance layer 100 in the composite wall 000 may include: a first steel plate 101, a second steel plate 102, and a first filling layer 103 located between the first and second steel plates 101, 102. The second steel plate 102 has a first through-hole A1 for receiving the first connector 400 and a second through-hole A2 for receiving the second connector 500. The first filling layer 103 may have a first connecting groove for receiving the first connector 400 and a second connecting groove for receiving the second connector 500. The first and second steel plates 101, 102 can function as a double-layer steel plate shear wall. When the wall is subjected to external impact, the first and second steel plates 101, 102 can share the load. Because steel plates have good load-bearing and energy-dissipating capabilities, the first and second steel plates 101, 102 in the first maintenance layer 100 can effectively resist external impact.

[0045] Furthermore, the filler layer enhances the integrity between the first steel plate 101 and the second steel plate 102 in the first protective layer 100, providing the first protective layer 100 with a more stable load-bearing capacity. Thus, when subjected to external impact, the first steel plate 101 and the second steel plate 102 in the first protective layer 100 can work together better, thereby offsetting the impact of the external environment and ensuring that the composite wall 000 has good impact resistance.

[0046] In order to more clearly see the matching relationship between the second maintenance layer 300 and the first connecting member 400 and the second connecting member 500, please refer to Figure 4 , Figure 4 This is another perspective provided by the embodiment of the present application Figure 2An exploded view of a composite wall is shown. The second maintenance layer 300 in the composite wall 000 may include: a third steel plate 301 and a fourth steel plate 302, and a second filling layer 303 located between the third and fourth steel plates 301, 302. The third steel plate 301 may have a third through hole A3 for passing the first connector 400, and a fourth through hole A4 for passing the second connector 500. The second filling layer 303 may have a third connecting groove for passing the first connector 400, and a fourth connecting groove for passing the second connector 500. The roles and functions of the third and fourth steel plates 301, 302 in the second maintenance layer 300 may refer to those of the first and second steel plates 101, 102 in the first maintenance layer 100. The roles and functions of the second filling layer 303 in the second maintenance layer 300 may refer to those of the first filling layer 103 in the first maintenance layer 100, and will not be further described here. It should be noted that each of the above-mentioned connecting grooves can be communicated with the through holes with corresponding numbers. For example, the first connecting groove can be communicated with the first through hole.

[0047] The structural layer 200 in the composite wall 000 can be located between the first maintenance layer 100 and the second maintenance layer 300. The structural layer 200 can have a first hole K1 for the first connector 400 and a second hole K2 for the second connector 500. Because the structural layer 200 can be located between the first maintenance layer 100 and the second maintenance layer 300, the composite wall 000 can achieve better overall performance through the structural layer 200. The first and second maintenance layers 100, 300 can also work together under the influence of the structural layer 200. This allows the composite wall 000 to withstand external impacts while all three layers, including the first, structural, and second maintenance layers, 300, can participate in the load-bearing process. This further improves the load-bearing capacity and energy dissipation capabilities of the composite wall 000.

[0048] For example, the structural layer 200 may include structural steel bars connected to the first and second maintenance layers 100 and 300, respectively. These steel bars effectively connect the structural layer 200 to the first and second maintenance layers 100 and 300, forming a composite wall 000. Furthermore, when the composite wall 000 is subjected to an external impact, the structural layer 200 can participate in the load not only through its contact surface with the first and second maintenance layers 100 and 300, but also through the structural steel bars connected to the first and second maintenance layers 100 and 300. This allows the structural layer 200 to better participate in the load-bearing and energy-dissipating capabilities of the composite wall 000.

[0049] The first steel plate 101, the second steel plate 102, the third steel plate 301 and the fourth steel plate 302 in the composite wall 000 can be rectangular in shape. One end of the first connecting member 400 in the composite wall 000 can be connected to the corner of the first steel plate 101 on the side of the first steel plate 101 close to the second steel plate 102, and the other end of the first connecting member 400 can be connected to the corner of the fourth steel plate 302 on the side of the fourth steel plate 302 close to the third steel plate 301. The orthographic projection of the axis of the first connecting member 400 on the first steel plate 101 can coincide with a diagonal line of the first steel plate 101. In this way, under the action of the first connecting member 400, the first maintenance layer 100, the second maintenance layer 300 and the structural layer 200 can better form an integrated structure. When the composite wall 000 is impacted by the external environment, the first connecting member 400 can transfer the deformation of the first steel plate 101 or the fourth steel plate 302 to other structures in the composite wall 000, so that the first maintenance layer 100, the second maintenance layer 300 and the structural layer 200 in the composite steel plate can cooperate better, thereby ensuring that the composite wall 000 has better bearing capacity and energy consumption capacity.

[0050] Here, the first connector 400 can be connected to the first steel plate 101 and the fourth steel plate 302 via the first through-hole A1 in the second steel plate 102 for passing the first connector 400, the third through-hole A3 in the third steel plate 301 for passing the first connector 400, and the first hole K1 in the structural layer 200 for passing the first connector 400. For example, after connecting to the first steel plate 101, the first connector 400 can pass through the first through-hole A1, the first hole K1, and the third through-hole A3 before connecting to the fourth steel plate 302. Furthermore, because the orthographic projection of the axis of the first connector 400 on the first steel plate 101 can coincide with a diagonal line of the first steel plate 101, that is, it can be arranged along two diagonally opposing corners of the first steel plate 101 and the fourth steel plate 302, when the composite wall 000 is impacted by the external environment, the first connector 400 can help other structures in the composite wall 000 resist the impact by generating tensile deformation. It should be noted that after the composite wall 000 is impacted by the external environment, the primary deformation forms of the first maintenance layer 100, the second maintenance layer 300, and the third maintenance layer are shear deformation and compressive deformation. Thus, because the composite wall 000 may also include the first connector 400, after the composite wall 000 is impacted by the external environment, the deformation of the various structures within the composite wall 000 can be more coordinated under the influence of the first connector 400, thereby avoiding the undesirable situation where a particular structure experiences severe shear deformation or compressive deformation, causing it to prematurely cease operation. Thus, through the first connector 400, the composite wall 000 not only has a high load-bearing capacity and energy dissipation capacity, but also has good ductility, thereby reducing the undesirable situation where the composite wall 000 suffers brittle failure after being subjected to a large external impact.

[0051] One end of the second connector 500 in the composite wall 000 can be connected to the corner of the first steel plate 101 on the side of the first steel plate 101 close to the second steel plate 102. The other end of the second connector 500 can be connected to the fourth steel plate 302 on the side of the fourth steel plate 302 close to the third steel plate 301. The orthographic projection of the axis of the first connector 400 on the first steel plate 101 can coincide with another diagonal line of the first steel plate 101. The role and function of the second connector 500 in the composite wall 000 can be referenced to the role and function of the first connector 400 in the composite wall 000 and will not be repeated here.

[0052] In summary, the present application provides a composite wall, comprising: a first protective layer, a structural layer, a second protective layer, a first connector, and a second connector. Through the first protective layer and the second protective layer, the composite wall can better resist impacts from the external environment. When subjected to impacts from the external environment, the steel plates in the first protective layer and the second protective layer can work together better, thereby offsetting the impact of the external environment, thereby ensuring that the composite wall has good impact resistance. Moreover, when the composite wall is subjected to impacts from the external environment, the structural layer can also better participate in the force of the composite wall, thereby enabling the composite wall to have a higher bearing capacity and energy dissipation capacity. In addition, under the action of the first connector and the second connector, the first protective layer, the second protective layer, and the structural layer can better form an integrated structure. When the composite wall is subjected to impacts from the external environment, the first connector and the second connector can transfer the deformation of the first steel plate or the fourth steel plate to other structures in the composite wall, thereby enabling the first protective layer, the second protective layer, and the structural layer in the composite steel plate to work together better, thereby ensuring that the composite wall has a better bearing capacity and energy dissipation capacity.

[0053] In the examples of this application, please refer to Figure 3 and Figure 4 The length of the first connector 400 can be equal to that of the second connector 500, and the cross-sectional dimensions of the first connector 400 and the second connector 500 can be equal. This allows the first connector 400 to better cooperate with the second connector 500. Furthermore, during production, the first connector 400 and the second connector 500 can be processed and formed simultaneously, further improving the production efficiency of the composite wall 000.

[0054] For example, because the length of the first connector 400 is equal to that of the second connector 500 and their dimensions are also equal, when the composite wall 000 is impacted by the external environment, the deformation of the first connector 400 and the second connector 500 can also be consistent. This ensures that the first connector 400 and the second connector 500 have the same lateral force resistance, thereby preventing the first connector 400 or the second connector 500 from prematurely stopping operation and causing damage to the composite wall 000.

[0055] It should be noted that the drawings in this application simplify the sizes and shapes of the first connector 400 and the second connector 500 for the sake of illustration. Figure 3 and Figure 4The dimensions of the cross sections of the first through hole A1, the second through hole A2, the third through hole A3, the fourth through hole A4, the first connecting groove, the second connecting groove, the third connecting groove, the fourth connecting groove, the first hole position K1, and the second hole position K2 in the composite wall 000 parallel to the first steel plate 101 can be equal to the dimensions of the cross sections of the first connector 400 and / or the second connector 500 parallel to the first steel plate 101. In this way, the first connector 400 can better pass through the first through hole A1, the third through hole A3, the first connecting groove, the third connecting groove, and the first hole position K1 to achieve connection with the first steel plate 101 and the fourth steel plate 302, and the second connector 500 can better pass through the second through hole A2, the fourth through hole A4, the second connecting groove, the fourth connecting groove, and the second hole position K2 to achieve connection with the first steel plate 101 and the fourth steel plate 302. In this way, it can be ensured that the first connecting member 400 and the second connecting member 500 can be fixed relatively stably in the composite wall 000. After the composite wall 000 is impacted by the external environment, the first connecting member 400 and the second connecting member 500 can better cooperate with other structures in the composite wall 000 to bear the force, thereby further improving the integrity of the composite wall 000.

[0056] For example, since the dimensions of the cross section of the first through hole A1, the second through hole A2, the third through hole A3, the fourth through hole A4, the first connecting groove, the second connecting groove, the third connecting groove, the fourth connecting groove, the first hole position K1 and the second hole position K2 in the composite wall 000 parallel to the first steel plate 101 can be equal to the dimensions of the cross section of the first connecting member 400 and / or the second connecting member 500 parallel to the first steel plate 101, the first filling layer 103, the second steel plate 102, the structural layer 200, the third steel plate 30 1 and the second filling layer 303 can be better connected with the first connecting member 400 and the second connecting member 500. After the composite wall 000 is impacted by the external environment, the deformation generated by the first filling layer 103, the second steel plate 102, the structural layer 200, the third steel plate 301 and the second filling layer 303 can be better transmitted to the first connecting member 400 and the second connecting member 500. The first connecting member 400 and the second connecting member 500 can also better coordinate the force of each layer structure in the composite wall 000.

[0057] In the embodiment of the present application, there are many ways to connect the two ends of the first connecting member 400 and the second connecting member 500 to the first steel plate 101 and the second steel plate 102. This application only schematically illustrates the following two possible implementations.

[0058] In one possible implementation, Figure 4As shown, both ends of the first connector 400 and the second connector 500 can be connected to the first steel plate 101 and the fourth steel plate 302 by welding. In this way, by welding, the first connector 400 and the second connector 500 can be connected to the first steel plate 101 and the fourth steel plate 302 in a fixed manner, thereby further improving the load-bearing capacity and energy dissipation capacity of the composite wall 000.

[0059] For another possible implementation, please refer to Figure 5 , Figure 5 : is a structural schematic diagram of another composite wall provided by an embodiment of the present application. The first steel plate 101 and the fourth steel plate 302 may have connection holes that allow the first connector 400 and the second connector 500 to pass through. The first connector 400 and the second connector 500 may extend out of the first steel plate 101 at one end close to the first steel plate 101, and the first connector 400 and the second connector 500 may extend out of the fourth steel plate 302 at one end close to the fourth steel plate 302. In addition, both ends of the first connector 400 and the second connector 500 may have a threaded structure, and the first connector 400 and the second connector 500 may be connected to the first steel plate 101 and the fourth steel plate 302 by means of a bolt connection through a connector L. In this way, by means of a bolt connection, the first connector 400 and the second connector 500 can be connected to the second steel plate 102 and the fourth steel plate 302 in a hinged manner. Thus, after the composite wall 000 is subjected to the ultimate impact of the external environment, the first connector 400 and the second connector 500 can better coordinate deformation with the various layers of the composite wall 000, and the first connector 400 and the second connector 500 can deform more significantly. Since the first connector 400 and the second connector 500 can be made of steel, the good ductility of steel can improve the ductility of the composite wall 000.

[0060] In the embodiment of the present application, the materials of the first filling layer 103, the second filling layer 303, and the structural layer 200 in the composite wall 000 are not particularly limited. The following materials are used for schematic illustration:

[0061] In the present application, the materials of the first filling layer 103 and the second filling layer 303 can be a first concrete or a perlite insulation material. Here, the first concrete can be foamed concrete. Because foamed concrete and perlite insulation materials are lightweight and have good insulation and ductility, the first filling layer 103 and the second filling layer 303 can ensure that the composite wall 000 has good insulation and ductility, while also ensuring that the composite wall 000 has a low weight. During the construction of the composite wall 000 for use in prefabricated buildings, operators can more conveniently adjust the position of the composite wall 000.

[0062] The structural layer 200 in the composite wall 000 can be made of a second concrete. Here, the second concrete can be a concrete composited with a fiber material. The fiber material can further enhance the ductility of the structural layer 200, allowing the second concrete to possess both good load-bearing capacity and good ductility. This can enhance the load-bearing capacity and energy dissipation capabilities of the composite wall 000. Furthermore, when subjected to external environmental impact, the composite wall 000 can undergo plastic failure. In this way, when the composite wall 000 is used as a protective wall of a road or bridge, after a vehicle collides with the protective wall panel, the composite wall 000 can exhibit good ductility, thereby better protecting the vehicle and avoiding the adverse situation where after the vehicle collides with the composite wall 000, the vehicle and the user carrying the vehicle suffer secondary injuries due to damage to the vehicle due to the high strength but poor ductility of the wall panel; when the composite wall 000 is used as a protective wall of a residence, the composite wall 000 can not only better insulate the residence, but also improve the seismic performance of the residence through its own good bearing capacity and ductility.

[0063] For example, the fiber material of the structural layer 200 in the composite wall 000 can be composited with the structural layer 200 in a variety of possible implementations. This application only schematically illustrates the following two possible implementations.

[0064] In one possible implementation, the fiber material can be combined with the second concrete in the form of aggregate. In this case, the second concrete comprises cement, fly ash, sand, fiber material, a water reducer, and water. The mass ratio of cement, fly ash, sand, and water is 1:1:0.76:0.55, with the fiber material accounting for 1.45% of the total volume of the second concrete and the water reducer accounting for 0.8% of the combined mass of cement, fly ash, and sand. This ensures the structural performance of the composite wall 000 while simplifying the installation process of the structural layer 200 within the composite wall 000, thereby further improving the production efficiency of the composite wall 000.

[0065] It should be noted that the present application also improves the mix ratio of the second concrete. Compared with the mix ratio of conventional concrete, the present application adjusts the mass ratio of cement, fly ash, sand and water in the second concrete, as well as the volume proportion of fiber material in the second concrete, so that the second concrete can better cooperate with the first connecting member 300 and the second connecting member 500 in the composite wall 000, thereby improving the bearing capacity, ductility and energy consumption capacity of the composite wall 000.

[0066] In another possible implementation, see Figure 6 , Figure 6This is a schematic diagram of the structure of another composite wall provided by an embodiment of the present application. Composite wall 000 may include a fiber layer 600, which comprises a first fiber layer 601 and a second fiber layer 602. The first fiber layer 601 is positioned between the concrete and the third steel plate 301, while the second fiber layer 602 is positioned between the concrete and the second steel plate 102. As such, the first fiber layer 601 and the second fiber layer 602 can directly participate in the load-bearing of composite wall 000, further improving its load-bearing capacity and energy dissipation capabilities.

[0067] For example, a bonding material may be provided between the first fiber layer 601 of the structural layer 200 and the second steel plate 102 and the first filling layer 103. Through the bonding material, the first fiber layer 601 may bond the second steel plate 102 and the structural layer 200. Here, the connection method of the second fiber layer 602 to the structural layer 200 and the third steel plate 301 can refer to the connection method of the first fiber layer 601 to the second steel plate 102 and the first filling layer 103, and will not be repeated here.

[0068] In the present application, the fiber material may be a polyvinyl chloride material or a carbon fiber material. The fiber layer 600 may be made of a carbon fiber material. Both polyvinyl chloride and carbon fiber materials are lightweight, high-strength, and have good ductility, thereby further improving the load-bearing capacity and energy dissipation capacity of the composite wall 000 and ensuring good ductility of the composite wall 000.

[0069] In the examples of this application, please refer to Figure 6The composite wall 000 may further include a plurality of sealing panels 700, which may be distributed on both sides of the composite wall 000. The normal of each sealing panel 700 may be parallel to the first steel plate 101, and the width of each sealing panel 700 may be equal to the sum of the thicknesses of the first protective layer 100, the structural layer 200, and the second protective layer 300. One side of each sealing panel 700 may be connected to the first steel plate 101, and the other side of each sealing panel 700 may be connected to the fourth steel plate 302. In this way, after the first steel plate 101, the second steel plate 102, the third steel plate 301, and the fourth steel plate 302 are positioned using the first connector 400 and the second connector 500, the first steel plate 101, the second steel plate 102, the third steel plate 301, and the fourth steel plate 302, in conjunction with the plurality of sealing plates 700, can form a cavity for pouring concrete. In other words, a construction formwork for the first filling layer 103, the second filling layer 303, and the structural layer 200 can be formed. This further improves the production efficiency of the composite wall 000. Furthermore, in areas where transportation is inconvenient, operators can transport the various components of the composite wall 000 separately. Upon arrival at the site, the composite wall 000 can be assembled according to actual conditions, and the first filling layer 103, the second filling layer 303, and the structural layer 200 can be poured using the formwork formed by the first steel plate 101, the second steel plate 102, the third steel plate 301, and the fourth steel plate 302 in conjunction with the plurality of sealing plates 700. In this way, the construction efficiency of the building using the composite wall 000 provided by this application can be further improved.

[0070] In summary, the present application provides a composite wall, comprising: a first protective layer, a structural layer, a second protective layer, a first connector, and a second connector. Through the first protective layer and the second protective layer, the composite wall can better resist impacts from the external environment. When subjected to impacts from the external environment, the steel plates in the first protective layer and the second protective layer can work together better, thereby offsetting the impact of the external environment, thereby ensuring that the composite wall has good impact resistance. Moreover, when the composite wall is subjected to impacts from the external environment, the structural layer can also better participate in the force of the composite wall, thereby enabling the composite wall to have a higher bearing capacity and energy dissipation capacity. In addition, under the action of the first connector and the second connector, the first protective layer, the second protective layer, and the structural layer can better form an integrated structure. When the composite wall is subjected to impacts from the external environment, the first connector and the second connector can transfer the deformation of the first steel plate or the fourth steel plate to other structures in the composite wall, thereby enabling the first protective layer, the second protective layer, and the structural layer in the composite steel plate to work together better, thereby ensuring that the composite wall has a better bearing capacity and energy dissipation capacity.
