Description

Technical Field

[0001] This invention relates to the field of earthquake-resistant structural technology, and in particular to a prefabricated steel frame wall structural system. Background Technology

[0002] In prefabricated construction, components are prefabricated in a factory and then transported to the construction site for assembly. Due to its advantages of energy saving, environmental friendliness, and short construction cycle, it has been widely used in the construction industry.

[0003] After the wall panels are prefabricated in the factory, they are generally quite heavy and cannot be moved manually. The transfer of wall panels usually relies on machinery, and the transfer of machinery is affected by the weather. Therefore, weather conditions have a significant impact on the construction period.

[0004] To improve the seismic performance of buildings, precast steel frame wall systems offer significant advantages. Compared to other energy-dissipating and vibration-damping structural systems, precast steel frame wall modular structures, with beams and columns forming a frame, jointly resist horizontal and vertical loads generated during operation (such as during earthquakes). Precast steel frame wall systems can be widely applied in multi-story and high-rise buildings, and are of significant practical importance for improving their seismic performance. Therefore, developing a precast steel frame wall modular structural system is particularly important. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by the present invention is to propose a prefabricated steel frame wall structure system that is simple to connect, flexible in layout, and easy to standardize and customize.

[0006] The technical solution adopted by this invention to solve its technical problem is to propose a prefabricated steel frame wall structure system, comprising:

[0007] Multiple steel frame wall modules are fixedly connected to form a frame. Each steel frame wall module includes a wall body and a beam-column frame. The beam-column frame includes a left column, a right column, an upper beam, and a lower beam. The left and right columns are spaced apart, and each column has several prestressed tendons. The two ends of the upper beam are connected to the upper ends of the left and right columns, respectively, and the two ends of the lower beam are connected to the lower ends of the left and right columns, respectively. The wall body is located between the left column, right column, upper beam, and lower beam. Each column, right column, upper beam, and lower beam is made of I-beams or T-beams, and each column has multiple bolt holes for bolts to pass through and connect adjacent steel frame wall modules.

[0008] At least two adjacent steel frame wall modules are connected in a straight line;

[0009] At least two adjacent steel frame wall modules are joined in an L-shape.

[0010] At least three of the steel frame wall modules are connected in a T-shape;

[0011] At least four of the steel frame wall modules are joined together in a cross shape.

[0012] Furthermore, multiple steel frame wall modules are arranged in multiple rows, columns, and layers to form the frame, and adjacent steel frame wall modules are fixedly connected.

[0013] Furthermore, both the left column and the right column are provided with multiple prestressing tendons, and each prestressing tendon is provided with multiple stirrups, which are attached to two adjacent prestressing tendons.

[0014] Both the left and right columns are provided with multiple rows and columns of bolts;

[0015] Multiple longitudinal reinforcement bars are provided near the joint between two adjacent steel frame wall modules.

[0016] Furthermore, when the left column, right column, upper crossbeam, and lower crossbeam are all constructed of I-beams,

[0017] The straight-line connection method between two adjacent steel frame wall modules is as follows: the left column of one steel frame wall module is attached to the right column of the other steel frame wall module, and bolts pass through the left column and the right column to fix the two together.

[0018] The L-shaped connection between two adjacent steel frame wall modules is as follows: the left column of one steel frame wall module is adjacent to and perpendicular to the right column of another steel frame wall module, and the two are fixedly connected by an L-shaped steel plate.

[0019] The T-shaped connection method between the three steel frame wall modules is as follows: the left columns of two steel frame wall modules are respectively set on both sides of the right column of one steel frame wall module in a T-shape, and the three are fixedly connected by two L-shaped steel plates respectively.

[0020] The cross-shaped connection method between the four steel frame wall modules is as follows: the left columns of the four steel frame wall modules are arranged in a cross shape and are adjacent to each other in sequence. Each of the four modules is fixedly connected to each other by four L-shaped steel plates.

[0021] Furthermore, the connection between the upper steel frame wall module and the lower steel frame wall module is as follows: the lower crossbeam of the upper steel frame wall module and the upper crossbeam of the lower steel frame wall module are fixedly connected by bolts.

[0022] Furthermore, the left columns of the upper steel frame wall module and the lower steel frame wall module are fixedly connected by a flat steel plate, and the right columns of the upper steel frame wall module and the lower steel frame wall module are fixedly connected by a flat steel plate.

[0023] Furthermore, when the left column, right column, upper crossbeam, and lower crossbeam are all set as T-shaped steel:

[0024] The straight-line connection method between two adjacent steel frame wall modules is as follows: the left column of one steel frame wall module is aligned and attached to the right column of the other steel frame wall module, and the two are fixedly connected by two flat steel plates respectively.

[0025] The L-shaped connection between two adjacent steel frame wall modules is as follows: the left column of one steel frame wall module is adjacent to and perpendicular to the right column of another steel frame wall module, and the two are fixedly connected by two L-shaped steel plates.

[0026] The T-shaped connection method between the three steel frame wall modules is as follows: the left columns of the two steel frame wall modules are respectively set on both sides of the right column of the one steel frame wall module in a T-shape, and the three are fixedly connected by two L-shaped steel plates and one flat steel plate.

[0027] The cross-shaped connection method between the four steel frame wall modules is as follows: the left columns of the four steel frame wall modules are arranged in a cross shape and are placed adjacent to each other in sequence. Two of the four modules are fixedly connected in pairs by four L-shaped steel plates to fix the four modules together.

[0028] Furthermore, the connection between the upper steel frame wall module and the lower steel frame wall module is as follows: the lower crossbeam of the upper steel frame wall module and the upper crossbeam of the lower steel frame wall module are fixedly connected by several flat steel plates;

[0029] The left columns of the upper steel frame wall module and the lower steel frame wall module are fixedly connected by a flat steel plate, and the right columns of the upper steel frame wall module and the lower steel frame wall module are fixedly connected by a flat steel plate.

[0030] Furthermore, when the steel frame wall modules are joined in a straight line, an L-shaped joint, a T-shaped joint, or a cross-shaped joint, a template is used to surround the circumference of the connection point, and the template and the steel frame wall module form a space for concrete pouring.

[0031] Furthermore, the upper crossbeam and the lower crossbeam have the same structure, and the left column and the right column have the same structure;

[0032] The steel frame wall module has a vertically symmetrical structure and a horizontally symmetrical structure.

[0033] Compared with the prior art, the present invention has at least the following beneficial effects:

[0034] In this invention, multiple steel frame wall modules are fixedly connected to form a frame, constituting the main structure of a prefabricated steel frame wall system. Each steel frame wall module consists of a beam-column frame and walls. The beam-column frame bears the load and jointly resists horizontal and vertical loads during earthquakes, while the walls themselves do not bear weight. The beam-column frame within the steel frame wall module includes a left column, a right column, an upper beam, and a lower beam. The left column, right column, upper beam, and lower beam are all made of I-beams or T-beams, facilitating the connection of the steel frame wall modules in this prefabricated steel frame wall structure. This system includes various connection methods such as straight joints, L-shaped joints, T-shaped joints, and cross-shaped joints, offering a wide variety of connection options and making connection very convenient. After connection, wooden formwork is used to enclose the joint, and concrete is poured. Once the concrete has solidified, the wooden formwork is removed, thus forming the prefabricated steel frame wall structure system. The concrete and the shear studs serve to position, limit, and stop movement. The prefabricated steel frame wall structure system of this scheme has a simple construction, a clear and well-defined stress mechanism, light weight, and strong energy dissipation capacity. The steel frame wall modules can be freely combined and connected. Furthermore, the steel frame wall modules are processed in the factory, ensuring quality and preventing leakage problems, while also enabling various integrated prefabrication methods, such as: integrated enclosure walls with insulation, heat insulation, and decoration; integrated interior partition walls with pipelines and decoration; lateral force resisting and non-lateral force resisting wall panels; and prefabricated integral connections. Moreover, when a single, single-layer, or single-row steel frame wall module is damaged during earthquake energy dissipation, local replacement is convenient.

[0035] In the structural system of this invention, the load is borne by a beam-column steel frame, while the walls of the house using this structure are not load-bearing and only serve the function of enclosure and partition. They can generally be constructed or assembled using prefabricated aerated concrete, expanded perlite, hollow bricks or porous bricks, pumice, vermiculite, ceramsite and other lightweight materials.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0059] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0060] Example 1:

[0061] like Figures 1-8 As shown, this embodiment is a prefabricated steel frame wall structure system. In this embodiment, the left column 11, right column 12, upper beam 13 and lower beam 14 are all made of I-beams.

[0062] A precast steel frame wall structure system, comprising:

[0063] Multiple steel frame wall modules 1 are fixedly connected to form a frame. Each steel frame wall module 1 includes a wall 10 and a beam-column frame. The beam-column frame includes a left column 11, a right column 12, an upper beam 13, and a lower beam 14. The left column 11 and right column 12 are spaced apart, and both the left column 11 and right column 12 are provided with several prestressing tendons 15. In this embodiment, multiple prestressing tendons 15 are provided, meaning both the left column 11 and right column 12 have multiple prestressing tendons 15. Multiple stirrups 16 are provided on each prestressing tendon 15, and the stirrups 16 are attached to adjacent prestressing tendons 15. In actual use, the prestressing tendons 15 can dissipate the energy input from earthquakes.

[0064] In this embodiment, the two ends of the upper crossbeam 13 are connected to the upper ends of the left column 11 and the right column 12, respectively, and the two ends of the lower crossbeam 14 are connected to the lower ends of the left column 11 and the right column 12, respectively. The wall 10 is set between the left column 11, the right column 12, the upper crossbeam 13, and the lower crossbeam 14. The left column 11, the right column 12, the upper crossbeam 13, and the lower crossbeam 14 are all provided with multiple bolt through holes 110, which allow bolts to pass through and connect adjacent steel frame wall modules 1 to each other. The multiple bolt through holes 110 on the left column 11, the right column 12, the upper crossbeam 13, and the lower crossbeam 14 make it convenient to connect the steel frame wall modules 1 on all four sides.

[0065] Furthermore, multiple steel frame wall modules 1 are arranged in multiple rows, columns, and layers to form a frame, and adjacent steel frame wall modules 1 are fixedly connected. In this scheme, the steel frame wall module 1 can be regarded as the smallest module in the prefabricated steel frame wall structure system. The structural system is formed by the fixed connection of multiple rows, columns, and layers of this smallest unit of steel frame wall module 1. When a single steel frame wall module 1, a single layer, or a single column is damaged during earthquake energy dissipation, it is also convenient to replace it locally.

[0066] Specifically, in this embodiment, both the left column 11 and the right column 12 are provided with multiple rows and columns of studs 18, which can enhance the strength of the structural system. In addition, to improve the strength of the system, multiple longitudinal ribs 17 are also provided near the joint between two adjacent steel frame wall modules 1.

[0067] In actual use, the precast steel frame wall structure system is supported by the beam and column steel frame, while the walls of the house using this structure are not load-bearing and only serve as enclosure and partition. Generally, it can be constructed or assembled using precast aerated concrete, expanded perlite, hollow bricks or porous bricks, pumice, vermiculite, ceramsite and other lightweight materials.

[0068] The various connection methods between steel frame wall modules 1 in this embodiment are described in detail below. It should be explained that in this embodiment, since the upper crossbeam 13 and lower crossbeam 14 have the same structure, and the left column 11 and right column 12 have the same structure, and the steel frame wall module 1 has both a vertically and horizontally symmetrical structure, the left column 11 and right column 12 are only used to distinguish their orientation; their actual structures are the same, their installation positions can be interchanged, and they serve the same function. Similarly, the upper crossbeam 13 and lower crossbeam 14 are only used to distinguish their orientation; their actual structures are the same, and their installation positions can be interchanged. Wherein:

[0069] like Figure 3 and Figure 4 As shown, in this embodiment, at least two adjacent steel frame wall modules 1 are connected in a straight line. The straight-line connection between two adjacent steel frame wall modules 1 is as follows: the left column 11 of one steel frame wall module 1 is attached to the right column 12 of another steel frame wall module 1, and bolts pass through both the left column 11 and the right column 12 to fix them together. Specifically, in this connection method, the I-beams of the left column 11 in the first steel frame wall module 1 and the right column 12 in the second steel frame wall module 1 are connected by bolts, and studs 18 are installed on their webs. Except for the bolted connections, all other connections are welded. Stirrups 16 and longitudinal reinforcement 17 are provided at the joint of the two steel frame wall modules 1. In the straight-line connection method, only bolts are needed to fix the two wall panels 10 together, which simplifies the construction.

[0070] like Figure 3 and Figure 5 As shown, in this embodiment, at least two adjacent steel frame wall modules 1 are connected in an L-shape. The L-shaped connection between two adjacent steel frame wall modules 1 is as follows: the left column 11 of one steel frame wall module 1 is adjacent to and perpendicular to the right column 12 of another steel frame wall module 1, and the two are fixedly connected by an L-shaped steel plate 2. Specifically, in this connection method, the left column 11 of one steel frame wall module 1 and the right column 12 of another steel frame wall module 1 are fixedly connected by an L-shaped steel plate 2 and bolts, and studs 18 are installed on its web. Except for the bolted connections, all other connections are welded.

[0071] like Figure 3 and Figure 6As shown, in this embodiment, at least three steel frame wall modules 1 are connected in a T-shape. The T-shaped connection between the three steel frame wall modules 1 is as follows: the left columns 11 of two steel frame wall modules 1 are respectively arranged on both sides of the right column 12 of one steel frame wall module 1 in a T-shape, and the three are fixedly connected by two L-shaped steel plates 2. Specifically, the three steel frame wall modules 1 are fixedly connected by two L-shaped steel plates 2 and bolts, and studs 18 are installed at their webs. Except for the bolted connections, all other connections are welded. Stirrups 16, prestressed tendons 15, and longitudinal reinforcement 17 are provided at the connection points.

[0072] like Figure 3 and Figure 7 As shown, in this embodiment, at least four steel frame wall modules 1 are connected in a cross shape. The cross-shaped connection method between the four steel frame wall modules 1 is as follows: the left columns 11 of the four steel frame wall modules 1 are arranged adjacently in a cross shape, and each pair of the four modules is fixedly connected by four L-shaped steel plates 2. Specifically, the four steel frame wall modules 1 are fixedly connected by L-shaped steel plates 2 and bolts, and studs 18 are installed on their webs. Except for the bolted connections, all other connections are welded. Prestressed tendons 15 and longitudinal reinforcement 17 are provided at the connection points.

[0073] In this embodiment, all types of connections—straight, L-shaped, T-shaped, and cross-shaped—are convenient, easy to construct, and offer good connection stability and high strength.

[0074] like Figure 8 As shown, in this embodiment, the connection between the upper steel frame wall module 1 and the lower steel frame wall module 1 is as follows: the lower crossbeam 14 of the upper steel frame wall module 1 and the upper crossbeam 13 of the lower steel frame wall module 1 are fixedly connected by bolts. Furthermore, the left columns 11 of both the upper and lower steel frame wall modules 1 are fixedly connected by flat steel plates 3, and the right columns 12 of both the upper and lower steel frame wall modules 1 are fixedly connected by flat steel plates 3.

[0075] When fixing and connecting the various steel frame wall modules 1 in this prefabricated steel frame wall structure system, only L-shaped steel plates 2, flat steel plates 3 and fixing bolts are needed, making the connection simple and convenient.

[0076] Example 2:

[0077] like Figures 9-14As shown, the difference between this embodiment and Embodiment 1 is that the left column 11, right column 12, upper beam 13, and lower beam 14 in this embodiment are all made of T-shaped steel instead of I-beams. The other structures are the same as in Embodiment 1. Because the left column 11, right column 12, upper beam 13, and lower beam 14 have changed compared to Embodiment 1, the method of connecting the various steel frame wall modules 1 in this embodiment is also different from that in Embodiment 1. Specifically:

[0078] like Figure 9 and Figure 10 As shown, in this embodiment, the straight-line connection between two adjacent steel frame wall modules 1 is as follows: the left column 11 of one steel frame wall module 1 is aligned and attached to the right column 12 of another steel frame wall module 1, and the two are fixedly connected by two flat steel plates 3 respectively. Specifically, the T-shaped steel of the two steel frame wall modules 1 is fixedly connected by flat steel plates 3 and bolts, and studs 18 are installed at their webs. Except for the bolted connections, all other connections are welded. Stirrups 16 and longitudinal bars 17 are provided at the connection positions.

[0079] like Figure 9 and Figure 11 As shown, in this embodiment, the L-shaped connection between two adjacent steel frame wall modules 1 is as follows: the left column 11 of one steel frame wall module 1 is adjacent to and perpendicular to the right column 12 of another steel frame wall module 1, and the two are fixedly connected by two L-shaped steel plates 2. Specifically, the two steel frame wall modules 1 are fixedly connected by L-shaped steel plates 2 and bolts. Except for the bolted connections, all other connections are welded, and studs 18 are installed on their webs. Stirrups 16 and longitudinal reinforcement 17 are provided at the connection positions.

[0080] like Figure 9 and Figure 12 As shown, in this embodiment, the T-shaped connection between the three steel frame wall modules 1 is as follows: the left columns 11 of two steel frame wall modules 1 are respectively arranged in a T-shape on both sides of the right column 12 of one steel frame wall module 1, and the three are fixedly connected by two L-shaped steel plates 2 and a flat steel plate 3. Specifically, the three steel frame wall modules 1 are fixedly connected by the flat steel plate 3, the L-shaped steel plate 2 and bolts, and a row of studs 18 is installed on their web. Except for the bolted connections, all other connections are welded. Stirrups 16 and longitudinal bars 17 are provided at the connection positions.

[0081] like Figure 9 and Figure 13As shown, in this embodiment, the cross-shaped connection between the four steel frame wall modules 1 is as follows: the left columns 11 of the four steel frame wall modules 1 are arranged adjacently in a cross shape, and two of the four are fixedly connected in pairs by four L-shaped steel plates 2 to secure the four modules together. Specifically, the four steel frame wall modules 1 are fixedly connected to their T-shaped steel sections by L-shaped steel plates 2 and bolts, and studs 18 are installed at their webs. Except for the bolted connections, all other connections are welded. Stirrups 16 and longitudinal reinforcement 17 are provided at the connection points.

[0082] like Figure 14 As shown, in this embodiment, the connection between the upper steel frame wall module 1 and the lower steel frame wall module 1 is as follows: the lower crossbeam 14 of the upper steel frame wall module 1 and the upper crossbeam 13 of the lower steel frame wall module 1 are fixedly connected by several flat steel plates 3. The left columns 11 of both the upper and lower steel frame wall modules 1 are fixedly connected by flat steel plates 3, and the right columns 12 of both the upper and lower steel frame wall modules 1 are fixedly connected by flat steel plates 3.

[0083] When fixing and connecting the various steel frame wall modules 1 in this prefabricated steel frame wall structure system, only L-shaped steel plates 2, flat steel plates 3 and fixing bolts are needed, making the connection simple and convenient.

[0084] In both Embodiment 1 and Embodiment 2, when the steel frame wall modules 1 are connected by a straight, L-shaped, T-shaped, or cross-shaped joint, a template 4 is used to surround the circumference of the connection point, and the template 4 and the steel frame wall module 1 form a space for concrete pouring.

[0085] Based on both Embodiment 1 and Embodiment 2, in the prefabricated steel frame wall structure system of the present invention: multiple steel frame wall modules 1 are fixedly connected to form a frame, forming the main structure of the prefabricated steel frame wall structure system. The steel frame wall module 1 is composed of a beam-column frame and a wall 10. The beam-column frame bears the load and resists the horizontal and vertical loads during earthquakes together, while the wall 10 of the building does not bear the load. The beam-column frame of steel frame wall module 1 includes a left column 11, a right column 12, an upper beam 13, and a lower beam 14. The left column 11, right column 12, upper beam 13, and lower beam 14 are all made of I-beams or T-beams, facilitating the connection of steel frame wall modules 1 in this precast steel frame wall structure. This system includes eight connection types: straight, L-shaped, T-shaped, and cross-shaped. The connection methods are diverse and convenient. After connection, wooden formwork 4 is used to enclose the joint, and concrete is poured. After the concrete hardens, the wooden formwork 4 is removed to form the precast steel frame wall structure system. The concrete and the shear studs 18 serve to position, limit, and stop movement. This precast steel frame wall structure system has a simple construction, a clear stress mechanism, is lightweight, and has strong energy dissipation capacity. The steel frame wall modules 1 can be freely combined and connected. Furthermore, the steel frame wall module 1 is processed in the factory, which can not only ensure quality and prevent problems such as leakage, but also realize various integrated prefabrication, such as: the integration of enclosure wall with insulation, heat insulation and decoration, the integration of internal partition wall with pipeline and decoration, lateral force resisting and non-lateral force resisting wall panels, and prefabricated integral connection, etc.

[0086] In this scheme, the prefabricated steel frame wall structure system is processed as a whole in the factory, which not only ensures quality and prevents problems such as leakage, but also enables various integrated prefabrication. The outstanding advantages of this structural system are not only its short construction cycle, no seasonal restrictions, less on-site wet work, high material utilization rate, green environmental protection, and good building energy performance, making it an ideal residential building system for promoting housing modernization, but also its advantages such as large building space, flexible layout, and ease of standardization and modularization, which can be widely used in multi-story and high-rise buildings.
