Description

Technical Field

[0001] This utility model relates to the field of cold-formed thin-walled steel structure building technology, and in particular to a cold-formed thin-walled steel rural house wall structure with energy dissipation function. Background Technology

[0002] Cold-formed thin-walled steel structures, with their significant advantages such as light weight, high strength, rapid construction, environmental friendliness, and high degree of industrialization, have been widely used in residential construction, especially in rural housing projects, becoming an energy-saving and environmentally friendly building form that aligns with the concept of sustainable development. To resist horizontal loads such as wind loads and seismic forces, these structures typically require diagonal bracing members in their walls to provide necessary lateral stiffness. Therefore, the performance of the connection nodes between the diagonal bracing and the wall frame (top guide beams, bottom guide beams, columns, etc.) directly affects the seismic safety and stability of the entire structure.

[0003] However, although energy-dissipating diagonal braces have been applied to cold-formed thin-walled steel rural house walls, the energy-dissipating part is part of the diagonal brace, that is, the energy-dissipating part is integrated with the diagonal brace. Its plastic deformation capacity is limited, and once it is damaged, the entire diagonal brace often needs to be replaced, resulting in high repair costs. This makes it difficult to meet the actual needs of rural house construction for structural repairability and economy. Utility Model Content

[0004] Based on the above analysis, the present invention aims to provide a cold-formed thin-walled steel rural house wall structure with energy dissipation function, in order to solve the problems of poor energy dissipation and high repair cost of existing cold-formed thin-walled steel rural house walls.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] A cold-formed thin-walled steel rural house wall structure with energy dissipation function includes a top guide beam, a bottom guide beam, columns, diagonal braces, and energy dissipation connectors; the top guide beam and the bottom guide beam are respectively located at the top and bottom ends of the columns, and the two ends of the diagonal braces are detachably connected to one end of an energy dissipation connector, and the other end of the energy dissipation connector is detachably connected to the top guide beam and the column, or the other end of the energy dissipation connector is detachably connected to the bottom guide beam and the column;

[0007] The thickness of the energy-consuming connector is less than the thickness of the connecting parts at both ends, and the energy-consuming connector is provided with a weakening structure, which is an elongated hole or an arc-shaped groove. The long axis of the elongated hole is perpendicular to the length direction of the diagonal brace, and the arc-shaped groove is provided at the middle edge of the energy-consuming connector to make the energy-consuming connector form a dog bone-like structure.

[0008] Furthermore, the energy-consuming connector has at least one elongated hole.

[0009] Furthermore, the energy-consuming connector is provided with a plurality of regularly arranged elongated holes.

[0010] Furthermore, it also includes a substrate, one end of which is detachably connected to the top guide beam and the column or to the bottom guide beam and the column, and the other end of which is detachably connected to the energy-consuming connector.

[0011] Furthermore, the energy-consuming connector has first screw holes at both ends.

[0012] Furthermore, the substrate is provided with a second screw hole.

[0013] Furthermore, it also includes cross braces, with multiple cross braces parallel to the top guide beam and the bottom guide beam; the top guide beam, the bottom guide beam, the column and the cross braces are connected to form a rectangular frame structure.

[0014] Furthermore, the rectangular frame structure has base plates at each of its four corners and diagonal braces on both sides.

[0015] Furthermore, the energy-consuming connector is made of low-yield-point steel.

[0016] Furthermore, the thickness of the energy-consuming connector is 1-1.5 mm.

[0017] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0018] (1) The two ends of the diagonal brace of this utility model are respectively connected to an energy-dissipating connector. The two ends of the energy-dissipating connector are detachably connected to the components they are connected to. The energy-dissipating connector is provided with a weakening structure. When the weakening structure is an elongated hole, its long axis is perpendicular to the length direction of the diagonal brace. When the weakening structure is an arc groove, the arc groove is located at the middle edge of the energy-dissipating connector, forming a dog bone structure. When the wall is subjected to a horizontal load, the plastic hinge is actively guided to form in this area through the energy-dissipating connector. By utilizing the excellent plastic deformation capacity of the low yield point steel, the energy dissipation efficiency of the node is greatly improved, and the damage is concentrated on the replaceable energy-dissipating connector, which effectively avoids the damage to the main structure of the wall and realizes the design concept of "damage control". If the energy-dissipating connector is damaged, the structural function can be restored simply by replacing the new energy-dissipating connector, which greatly reduces maintenance costs and time.

[0019] (2) The energy-dissipating connector of this utility model has at least one elongated hole, the long axis of which is approximately perpendicular to the axis of the diagonal brace, to ensure that the energy-dissipating core area can undergo tensile or compressive plastic deformation in a predetermined direction when the diagonal brace is under tension or compression. The energy-dissipating connector is connected to other components by screws. When the energy-dissipating connector needs to be replaced, the screws can be loosened to quickly replace the new energy-dissipating connector. When the diagonal brace is under tension or compression, the force is transmitted to the energy-dissipating connector through the screws, and the stress concentration causes it to undergo plastic tensile, bending or bulging deformation first, absorbing and dissipating energy in the process.

[0020] (3) One end of the energy-dissipating connector of this utility model is connected to the diagonal brace by a screw, and the other end of the energy-dissipating connector is connected to the base plate by a screw. The thickness of the energy-dissipating connector is less than the thickness of the diagonal brace and the thickness of the base plate. When the wall is subjected to a horizontal load, the force is transmitted to the energy-dissipating connector through the diagonal brace. Since the plate in the energy-dissipating core area is thinner and has a weakening structure, its stiffness is relatively small, and the stress will first concentrate here. After the load reaches a certain level, the energy-dissipating connector will enter the plastic yielding state first, and dissipate a large amount of seismic energy through repeated plastic deformation of the metal (such as bending and stretching), thereby protecting the main load-bearing components such as the diagonal brace and the column from damage. Even if the energy-dissipating connector is damaged, it is only necessary to replace the energy-dissipating connector, which is convenient for post-disaster repair.

[0021] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing this invention. The objectives and other advantages of this invention can be realized and obtained from the details specifically pointed out in the text and accompanying drawings. Attached Figure Description

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0032] A specific embodiment of this utility model, combined with Figure 1 , Figure 2 and Figure 5 As shown, a cold-formed thin-walled steel rural house wall structure with energy dissipation function (hereinafter referred to as cold-formed thin-walled steel rural house wall structure) is disclosed, including a top guide beam 1, a bottom guide beam 2, a column 3, a diagonal brace 4, and an energy dissipation connector 5. The top guide beam 1 and the bottom guide beam 2 are respectively located at the upper and lower ends of the column 3. An energy dissipation connector 5 is connected to each end of the diagonal brace 4. One end of the energy dissipation connector 5 is detachably connected to the diagonal brace 4, and the other end of the energy dissipation connector 5 is detachably connected to the top guide beam 1 and the column 3 or to the bottom guide beam 2 and the column 3. The thickness of the energy dissipation connector 5 is less than the thickness of the connecting parts at both ends, and the energy dissipation connector 5 is provided with a weakening structure, which is an elongated hole 51 or an arc-shaped groove 52. The long axis of the elongated hole 51 is perpendicular to the length direction of the diagonal brace 4, and the arc-shaped groove 52 is located at the middle edge of the energy dissipation connector 5 to form a dog-bone structure.

[0033] Compared with the prior art, the cold-formed thin-walled steel rural house wall structure provided in this embodiment has an energy-dissipating connector 5 connected to each end of the diagonal brace 4. The two ends of the energy-dissipating connector 5 are detachably connected to the components they are connected to, and the energy-dissipating connector 5 is provided with a weakening structure. When the weakening structure is an oblong hole 51, its long axis is perpendicular to the length direction of the diagonal brace 4. When the weakening structure is an arc groove 52, the arc groove 52 is located at the middle edge of the energy-dissipating connector 5, forming a dog bone structure. When the wall is subjected to a horizontal load, the plastic hinge is actively guided to form in this area through the energy-dissipating connector 5. By utilizing the excellent plastic deformation capacity of the low yield point steel, the energy dissipation efficiency of the node is greatly improved, and the damage is concentrated on the replaceable energy-dissipating connector 5, which effectively avoids the damage to the main structure of the wall and realizes the design concept of "damage control". If the energy-dissipating connector 5 is damaged, the structural function can be restored simply by replacing the new energy-dissipating connector 5, which greatly reduces maintenance costs and time.

[0034] like Figure 2 and Figure 3 As shown, when the weakening structure is an elongated hole 51, the energy-dissipating connector 5 has at least one elongated hole 51.

[0035] like Figure 4 As shown, the energy-dissipating connector 5 has a plurality of regularly arranged elongated holes 51, preferably three in number. The long axis of the elongated holes 51 is approximately perpendicular to the axis of the diagonal brace 4 to ensure that when the diagonal brace 4 is under tension or compression, the energy-dissipating core area can undergo tensile or compressive plastic deformation in a predetermined direction.

[0036] To facilitate the connection of the energy-consuming connector 5 with other components, such as Figure 3 , Figure 4 and Figure 5 As shown, the energy-consuming connector 5 has first screw holes 53 at both ends. The energy-consuming connector 5 is connected to other components by screws. When the energy-consuming connector 5 needs to be replaced, the screws can be loosened and a new energy-consuming connector 5 can be replaced to restore the structural function, which greatly reduces maintenance costs and time.

[0037] Preferably, the energy-dissipating connector 5 is made of low-yield-point steel, such as LY100 or LY160. The thickness of the energy-dissipating connector 5 is 1-1.5 mm.

[0038] In this embodiment, when the diagonal brace 4 is under tension or compression, the force is transmitted to the energy dissipation connector 5 through the screw. Since the plate in this area is thin and has openings (such as oblong holes 51), the stress concentration causes it to undergo plastic stretching, bending or bulging deformation first, and absorbs and dissipates energy in the process.

[0039] like Figure 1 and Figure 2As shown, the cold-formed thin-walled steel rural house wall structure also includes a base plate 6. One end of the base plate 6 is connected to the top guide beam 1 and the column 3 simultaneously, or to the bottom guide beam 2 and the column 3 simultaneously, such as by self-tapping screws; the other end of the base plate 6 is detachably connected to the energy-dissipating connector 5. The thickness of the base plate 6 is greater than the thickness of the energy-dissipating connector 5.

[0040] Understandably, in order to achieve a detachable connection between the substrate 6 and the power-dissipating connector 5, such as Figure 6 As shown, the substrate 6 has a second screw hole 61.

[0041] Preferably, the substrate 6 is a rectangular plate.

[0042] In this embodiment, one end of the energy-dissipating connector 5 is connected to the diagonal brace 4 by a screw, and the other end is connected to the base plate 6 by a screw. The thickness of the energy-dissipating connector 5 is less than the thickness of the diagonal brace 4 and the thickness of the base plate 6. When the wall is subjected to a horizontal load, the force is transmitted to the energy-dissipating connector 5 through the diagonal brace 4. Because the plate in the energy-dissipating core area is thinner and has a weakening structure, its stiffness is relatively small, and stress will first concentrate here. After the load reaches a certain level, the energy-dissipating connector 5 will be the first to enter the plastic yielding state, dissipating a large amount of seismic energy through repeated plastic deformation of the metal (such as bending and stretching), thereby protecting the main load-bearing components such as the diagonal brace 4 and the column 3 from damage. Even if the energy-dissipating connector 5 is damaged, only the energy-dissipating connector 5 needs to be replaced, which is convenient for post-disaster repair.

[0043] like Figure 1 and Figure 2 As shown, the Lengwang thin-walled steel rural house wall structure also includes horizontal braces 7, which are parallel to the top guide beam 1 and the bottom guide beam 2 and are evenly distributed between them. Each end of the horizontal brace 7 is connected to a column 3, and the middle of the horizontal brace 7 passes through multiple columns 3 and connects to the passing columns 3. A rectangular frame structure is formed by connecting the top guide beam 1, the bottom guide beam 2, the columns 3, and the horizontal braces 7. Base plates 6 are provided at the four corners of both sides of the rectangular frame structure, and diagonal braces 4 are provided on both sides of the rectangular frame structure. The diagonal braces 4 and the energy-dissipating connectors 5 are located on the diagonals of the rectangular frame structure.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
