Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, and in particular to an embedded wall connection kit. Background Technology

[0002] The walls of steel-framed buildings can be either externally mounted or internally embedded. Compared to externally mounted walls, internally mounted walls offer several advantages, such as: reduced wall thickness, elimination of protruding beams and columns, and more efficient use of building space; close integration with the main building structure, improving the overall structural rigidity and stability; and high-efficiency thermal insulation, which helps improve building energy efficiency and reduce energy consumption.

[0003] The connection between the embedded wall and the steel frame is typically achieved using rigid connectors. During use, the wall is subjected not only to in-plane horizontal loads but also to out-of-plane horizontal loads (such as wind loads). When subjected to horizontal loads (e.g., wind loads), the steel frame undergoes horizontal displacement relative to the frame beams, resulting in bending deformation. Because of the rigid connectors between the embedded wall and the steel frame, the wall itself also undergoes bending deformation. This mismatch in deformation between the wall and the steel frame can lead to cracks or even damage in the wall, especially at the connection points with the rigid connectors. This can result in adverse consequences such as water leakage, impaired building functionality, and reduced out-of-plane load-bearing capacity of the wall. Utility Model Content

[0004] This utility model provides an embedded wall connection kit to solve the technical problem of inconsistent deformation between the wall and the steel frame, which leads to cracks or even damage in the wall, especially at the connection between the wall and the rigid connector.

[0005] To address the aforementioned technical problems, this utility model provides an embedded wall connection kit, disposed between the embedded wall and a steel frame. The embedded wall connection kit includes:

[0006] The U-shaped connector includes a web and flanges at both ends of the web. The U-shaped connector is used to be fitted onto the embedded wall, so that the flanges at both ends are fixedly connected to the two sides of the embedded wall. A gap is formed between the web and the embedded wall.

[0007] The S-shaped connector has its first end fixedly connected to the side of the steel frame facing the embedded cavity, and its second end inserted downward from above the U-shaped connector into the gap and locked between the web and the embedded wall.

[0008] Furthermore, the U-shaped connector and the S-shaped connector are formed by bending steel plates.

[0009] Furthermore, the flange is detachably connected to the inner cavity.

[0010] Furthermore, the second end of the S-shaped connector is inserted into the gap and clamped between the web and the embedded wall by the U-shaped connector, so that one side of the S-shaped connector abuts against the web and the other side abuts against the embedded wall.

[0011] Furthermore, the web plate is provided with a first threaded hole for engaging with a fastening bolt. The second end of the S-shaped connector is inserted into the gap, and the fastening bolt is screwed into the first threaded hole so that the end of the fastening bolt abuts against one side of the S-shaped connector and the other side abuts against the embedded wall.

[0012] Furthermore, the S-shaped connector includes a first connecting portion, a first supporting portion, a deformable portion, a second supporting portion, and a second connecting portion that are fixedly connected in sequence. The first connecting portion and the second connecting portion are parallel and opposite to each other. The first supporting portion and the second supporting portion are parallel and staggered. The first supporting portion is located above the second supporting portion. The first supporting portion and the second supporting portion are located between the first connecting portion and the second connecting portion, and the length directions of the first supporting portion and the second supporting portion are perpendicular to each other. The deformable portion is located between the first supporting portion and the second supporting portion.

[0013] Furthermore, the second connecting part is detachably connected to the steel frame.

[0014] Furthermore, the second connecting part is provided with a second threaded hole, which is used to cooperate with a bolt to fix the second connecting part to the steel frame.

[0015] Furthermore, the first support portion and the second support portion are completely offset from each other, and the end of the first support portion near the deformable portion and the end of the second support portion near the deformable portion are spaced apart in the horizontal direction, so that the deformable portion is inclined outward and downward.

[0016] The beneficial effects of this utility model embodiment:

[0017] The first end of the S-shaped connector of this utility model is fixedly connected to the steel frame, and the flanges at both ends of the U-shaped connector are fixedly connected to the embedded wall. The second end of the S-shaped connector is clamped between the web of the U-shaped connector and the embedded wall through the web of the U-shaped connector. Due to its shape characteristics, the S-shaped connector is a flexible connector. When subjected to wind loads perpendicular to the embedded wall, the S-shaped connector can undergo lateral bending deformation, achieving deformation coordination between the steel frame and the embedded wall within the wall surface. This prevents the embedded wall from being subjected to excessive horizontal thrust, thus protecting the wall while meeting the load-bearing capacity and deformation requirements of the embedded wall.

[0028] Please refer to Figures 1 to 4 This utility model embodiment provides an embedded wall connection kit, disposed between the embedded wall 12 and the steel frame 11. The embedded wall connection kit includes:

[0029] The U-shaped connector 14 includes a web 142 and flanges 141 disposed at both ends of the web 142. The U-shaped connector 14 is used to fit around the embedded wall 12, so that the flanges 141 at both ends are fixedly connected to the two sides of the embedded wall 12, and a gap is formed between the web 142 and the embedded wall 12.

[0030] S-shaped connector 13, the first end of which is fixedly connected to the side of the steel frame 11 facing the embedded cavity, and the second end of which is inserted downward from above the U-shaped connector 14 into the gap and locked between the web plate 142 and the embedded wall 12.

[0031] like Figure 2 As shown, specifically, the flanges 141 at both ends are fixedly connected to the two sides of the embedded wall 12, indicating that the flanges 141 and the embedded wall 12 can be fixed by screws or adhesives. In this embodiment, the flanges 141 and the embedded wall 12 are fixed by screws.

[0032] Specifically, the flange 141 is detachably connected to the inner cavity. The second connecting part 135 is detachably connected to the steel frame 11. This facilitates on-site assembly.

[0033] like Figure 4 As shown, the flange 141 is provided with a third threaded hole 1411, which is used to engage with a bolt or screw to fix the flange 141 to the embedded wall 12. Preferably, the third threaded hole 1411 is engaged with a screw, the outer periphery of which is provided with external threads, which are screwed into the third threaded hole 1411. The end of the screw is driven into the embedded wall 12, thus fixing the flange 141 to the embedded wall 12 for a more secure connection.

[0034] Preferably, the flange 141 is a flat plate, with the flanges 141 at both ends arranged in parallel, and one end of the flange 141 is vertically connected to the end of the web 142. The web 142 of the U-shaped connector 14 is arranged horizontally, and the flanges 141 at both ends are perpendicular to the web 142. Typically, the end faces of adjacent sides of the wall are arranged vertically and the connected ends form a right angle. The connection between the flange 141 of the U-shaped connector 14 and the web 142 also forms a right angle, which can better adapt to the shape of the embedded wall 12.

[0035] like Figure 1 As shown, specifically, the S-shaped connector 13 has two openings, with the opening near the first end facing upwards and the opening near the second end facing downwards. The first end of the S-shaped connector 13 can be fixed by screwing, welding, or bonding. In this embodiment, the S-shaped connector 13 is fixedly connected to the steel frame 11 by screwing. With the opening near the second end of the S-shaped connector 13 facing downwards, the second end of the S-shaped connector 13 is inserted into the gap from top to bottom, so that the second end is locked onto the U-shaped connector 14 and will not fall off. At this time, the S-shaped connector 13 is clamped between the U-shaped connector 14 and the embedded wall 12 by the U-shaped connector 14, so that the second end of the S-shaped connector 13 is fixedly connected.

[0036] In this embodiment, the first end of the S-shaped connector 13 is fixedly connected to the steel frame 11, and the flanges 141 at both ends of the U-shaped connector 14 are fixedly connected to the embedded wall 12. The second end of the S-shaped connector 13 is clamped between the web 142 and the embedded wall 12 through the web 142 of the U-shaped connector 14. Due to its shape characteristics, the S-shaped connector 13 is a flexible connector. When subjected to wind loads perpendicular to the embedded wall 12, the S-shaped connector 13 can undergo lateral bending deformation, achieving deformation coordination between the steel frame 11 and the embedded wall 12 within the wall surface. This prevents the embedded wall 12 from being subjected to excessive horizontal thrust, thus protecting the wall while meeting the load-bearing and deformation requirements outside the embedded wall 12.

[0037] It is understandable that the S-shaped connector 13 and the U-shaped connector 14 can be formed by bending steel plates. The S-shaped connector 13 is used as a buffer. Its load-bearing capacity and stiffness are sufficient to ensure that the S-shaped connector 13 is not damaged under wind load. Furthermore, the embedded wall 12 in the plane will not have excessive displacement relative to the steel frame 11.

[0038] Specifically, the second end of the S-shaped connector 13 is locked between the web 142 and the embedded wall 12, including two connection methods.

[0039] The first connection method: The second end of the S-shaped connector 13 is inserted into the gap and clamped between the web 142 and the embedded wall 12 by the U-shaped connector 14, so that one side of the S-shaped connector 13 abuts against the web 142 and the other side abuts against the embedded wall 12. In this way, the structure is simple, and the second end of the S-shaped connector 13 can be fixed by clamping.

[0040] The second connection method: The web plate 142 is provided with a first threaded hole 1421, which is used to mate with a fastening bolt 15. The second end of the S-shaped connector 13 is inserted into the gap, and the fastening bolt 15 is screwed into the first threaded hole 1421, so that the end of the fastening bolt 15 abuts against one side of the S-shaped connector 13 and the other side abuts against the embedded wall 12. In this way, the S-shaped connector 13 can be clamped between the web plate 142 and the embedded wall 12 by the fastening bolt 15. Moreover, after the S-shaped connector 13 is deformed, the fastening bolt 15 can be rotated in the opposite direction to loosen the second end of the S-shaped connector 13, which is convenient for replacing the S-shaped connector 13 without disassembling the U-shaped connector 14. The operation is simple.

[0041] It is understood that the S-shaped connector 13 in this embodiment is preferably connected to the U-shaped connector 14 using the second connection method.

[0042] like Figure 3As shown, specifically, the S-shaped connector 13 includes a first connecting portion 131, a first supporting portion 132, a deformable portion 133, a second supporting portion 134, and a second connecting portion 135 that are fixedly connected in sequence. The first connecting portion 131 and the second connecting portion 135 are parallel and opposite to each other. The first supporting portion 132 and the second supporting portion 134 are parallel and staggered. The first supporting portion 132 is located above the second supporting portion 134. The first supporting portion 132 and the second supporting portion 134 are located between the first connecting portion 131 and the second connecting portion 135. The length direction of the first supporting portion 132 and the second supporting portion 134 is perpendicular to the length direction of the first connecting portion 131 and the second connecting portion 135. The deformable portion 133 is located between the first supporting portion 132 and the second supporting portion 134.

[0043] Specifically, the first connecting part 131, the first supporting part 132, the deformable part 133, the second supporting part 134, and the second connecting part 135 are fixedly connected in sequence, meaning that one end of the first connecting part 131 is fixedly connected to one end of the first supporting part 132, the other end of the first supporting part 132 is fixedly connected to one end of the deformable part 133, the other end of the deformable part 133 is fixedly connected to one end of the second supporting part 134, and the other end of the second supporting part 134 is fixedly connected to one end of the second connecting part 135.

[0044] Since the steel frame 11 is usually arranged parallel to the embedded wall 12, the first connecting part 131 and the second connecting part 135 are arranged parallel to each other. The first connecting part 131 and the second connecting part 135 are arranged opposite each other, and the first support part 132 and the second support part 134 are arranged parallel and staggered, so that the deformation part 133 is inclined. When subjected to wind load perpendicular to the embedded wall 12, the deformation of the steel frame 11 and the embedded wall 12 in the wall surface is inconsistent. The deformation part 133 can be laterally bent, so as to realize the deformation coordination of the steel frame 11 and the embedded wall 12 in the wall surface. In addition, the horizontal deformation of the deformation part 133 can also buffer the thrust of the wind load on the deformation part 133 perpendicular to the embedded wall 12, so as to protect the embedded wall 12.

[0045] Specifically, the first support portion 132 and the second support portion 134 are completely offset. The end of the first support portion 132 near the deformation portion 133 and the end of the second support portion 134 near the deformation portion 133 are horizontally spaced, so that the deformation portion 133 is inclined outward and downward. In this way, the movement distance of one end of the deformation portion 133 towards the steel frame 11 or the embedded wall 12 can be increased, thereby increasing the buffering force on the steel frame 11 and the embedded wall 12.

[0046] Specifically, the deformable part 133 is a flat plate, and the stress of the deformable part 133 is concentrated at the position connecting the first support part 132 and the second support part 134. The deformable part 133 itself is not easy to break.

[0047] Preferably, the first connecting part 131 and the second connecting part 135 are flat plates, which can increase the contact area with the embedded wall 12 and the steel frame 11. When the S-shaped connector 13 is under force, the force is dispersed, so that the S-shaped connector 13 can withstand a large force and is not easy to damage the inner cavity wall, thus achieving the effect of protecting the embedded wall 12.

[0048] Specifically, the second connecting part 135 is provided with a second threaded hole 1351, which is used to cooperate with a bolt to fix the second connecting part 135 to the steel frame 11.

[0049] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above are merely specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. In particular, it should be noted that any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model for those skilled in the art.
