Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to a component-type curtain wall corner column connection device. Background Technology

[0002] With the rapid development of my country's construction industry, the shapes of main buildings are changing daily, leading to increasingly diverse curtain wall designs. Corner mullions are a crucial component of the curtain wall system, serving as transitional elements between different wall surfaces and bearing loads from various directions, primarily wind loads. In curtain wall design, corner mullions are typically categorized into large corner mullions and small corner mullions based on their stress conditions, size, and location.

[0003] Currently, modular curtain wall systems are only a common form of external envelope structure. Both large and small columns can be installed at corners. However, large columns at corners can affect the transparency of views from the interior. As people demand higher levels of detail and aesthetic appeal in architecture, corresponding design requirements have emerged. Unlike the previous use of large corner columns, small corner columns allow for more continuous and aesthetically pleasing connections between interior beams, weakening the corner separation and making the corner smoother. This results in better and more open views at the corner. Existing glass curtain wall corner column connections use adapters, and clamping columns are connected with bolts. For small corner columns, the clamps cannot penetrate the column for secure clamping, and the original corner connection method cannot meet the actual needs of on-site applications.

[0004] In summary, a connection device is needed for the small corner columns of modular curtain walls. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a component-type curtain wall corner column connection device. By setting a transition steel plate and two connectors, two curtain wall transition pieces can be connected to the column. Especially for small corner columns, the connection can be achieved without penetrating the column or damaging the internal structure of the column, and it also avoids the indoor bolts being exposed and affecting the aesthetics.

[0006] The technical solution of this utility model is: A component-type curtain wall corner column connection device, used to connect two curtain wall transition pieces to a column, comprising: The adapter steel plate is L-shaped. One side of the adapter steel plate is used to abut against the corner of the column, and the other side of the adapter steel plate is used to fix one end of the two curtain wall adapter pieces. Two connectors are symmetrically arranged on the transition steel plate, and the two connectors are used to connect the transition steel plate to both sides of the corner of the column; A limiting element is provided on the adapter steel plate, and the limiting element is used to prevent the adapter steel plate from deflecting.

[0007] Preferably, the connector includes: Two bolts are provided, and through holes are respectively opened on the side walls of the adapter steel plate and the column, and the two bolts are respectively inserted into the through holes.

[0008] Preferably, the through hole is a keyhole, which is opened along the length of the adapter steel plate, and the two bolts are respectively inserted into the keyhole.

[0009] Preferably, the limiting component consists of two screws, which are threaded onto the adapter plate and the column, respectively, and the two screws are located below the bolts in the two connecting components.

[0010] Preferably, it also includes: A gasket is fitted onto the bolt, and one side of the gasket is welded to the adapter plate.

[0011] Preferably, the gasket is a steel sheet, which is welded to the transition steel plate.

[0012] Preferably, the adapter steel plate, the two connecting parts and the limiting part are a set of connecting structures, and there are two sets of connecting structures, which are distributed along the axial direction of the column.

[0013] Preferably, the spacing between the transition steel plates in the two sets of connection structures is 450mm-600mm.

[0014] Preferably, the spacing between the transition steel plates in the two sets of connection structures is 500mm.

[0015] Compared with the prior art, the component-type curtain wall corner column connection device provided by this utility model has the following advantages: This device connects two curtain wall transition pieces to a column by using a transition steel plate and two connectors. It is particularly useful for small corner columns, achieving a connection without penetrating the column or damaging its internal structure, and also avoids exposed bolts affecting aesthetics. In use, the ends of the two curtain wall transition pieces are first welded to the transition steel plate. The welded structure is then connected to the column via the two connectors, thus achieving the connection between the two curtain wall transition pieces and the column. After connection, a limiting device prevents the transition steel plate from deflecting, further ensuring a stable connection between the two curtain wall transition pieces and the column.

[0017] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0018] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] Furthermore, in the description of this utility model, "a plurality of" refers to two or more. The terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] Example 1 like Figure 1 As shown, this utility model provides a component-type curtain wall corner column connecting device for connecting two curtain wall adapters 1 and columns 4, including: adapter steel plate 2, connectors, and limiting components. The adapter steel plate 2 is L-shaped, that is, the L-shaped plate includes two perpendicular plates. One side of the adapter steel plate 2 (the inner side of the right angle between the two plates, that is, the two sides with an included angle of 90°) is used to abut against the corner of the column 4. The shape of the adapter steel plate 2 conforms to the corner shape of the column 4. The other side of the adapter steel plate 2 (the outer side of the right angle between the two plates, that is, the two sides with an included angle of 270°) is used to fix one end of the two curtain wall adapters 1, such as... Figure 4As shown, the ends of the two curtain wall transition pieces 1 form a right angle, and the ends of the two curtain wall transition pieces 1 are welded to the two sides of the transition steel plate 2 at an angle of 270°. Two connectors are symmetrically arranged on the transition steel plate 2, that is, on the two sides of the transition steel plate 2 at an angle of 90°. The two connectors are used to connect the transition steel plate 2 to the corners of the column 4. A limiting piece is arranged on the transition steel plate 2 to prevent the transition steel plate 2 from deflecting, making the connection between the two curtain wall transition pieces 1 and the column 4 more stable. In use, the ends of the two curtain wall transition pieces 1 can be welded to the transition steel plate 2 first, and then the welded integrated structure can be connected to the column 4 through the two connectors, thereby realizing the connection between the two curtain wall transition pieces 1 and the column 4. After the connection is completed, the limiting piece prevents the transition steel plate 2 from deflecting, further realizing the stable connection between the two curtain wall transition pieces 1 and the column 4. This device connects two curtain wall transition pieces 1 to the columns 4 using a transition steel plate 2 and two connectors. It is particularly useful for small corner columns, achieving connection without penetrating the column or damaging its internal structure, and also avoids exposed bolts affecting aesthetics. The transition steel plate 2 and the curtain wall transition pieces 1 are welded together, allowing them to be pre-welded to form a single structure for on-site installation with the smaller columns.

[0022] This embodiment provides a specific structure for a connector. Further, the connector includes two bolts 3. Through holes 5 are respectively provided on the side walls of the transition steel plate 2 and the column 4. The positions and sizes of the through holes 5 on the transition steel plate 2 and the column 4 correspond, and the two bolts 3 are respectively inserted into the through holes 5. This embodiment achieves the connection between the transition steel plate 2 and the column 4 by providing corresponding through holes 5 on both the transition steel plate 2 and the column 4, and matching the bolts 3 within the through holes 5 on both the transition steel plate 2 and the column 4. The transition steel plate 2 is welded to the curtain wall transition component 1, thereby achieving the connection between the column 4 and the curtain wall transition component 1. In this embodiment, the bolts 3 are fixed on both sides of the column 4, not penetrating through it. Therefore, the heads of the bolts 3 will not be exposed indoors, ensuring the aesthetics and consistency of the exterior facade.

[0023] like Figure 2 , Figure 3As shown, the through hole 5 is further designed as a keyhole, meaning its shape resembles a key. The through hole 5 includes interconnected circular and strip-shaped holes. The circular holes are located at the bottom, and the keyholes are formed along the length of the adapter steel plate 2. Two bolts 3 are respectively inserted into the keyholes. Because the ends of the bolts 3 are relatively large, the keyholes allow the ends of the bolts 3 to pass through the circular holes at the bottom of the keyholes. After passing through, the ends move upwards, allowing the shank to pass through the strip-shaped holes. Since the small column cavity is small, keyholes are needed for the bolts 3 to pass through. In this embodiment, the keyholes allow the hexagonal head of the bolt 3 to be inserted into the column 4 from any position and then locked to the external L-shaped adapter steel plate 2. In this embodiment, during connection, one end of the bolt 3 is first inserted through the keyhole on the column 4, and then the other end of the bolt 3 is inserted through the keyhole on the adapter steel plate 2, so that the shank of the bolt 3 passes through both keyholes.

[0024] To further solidify the connection, such as Figure 3 As shown, it also includes: a washer 6 fitted onto the bolt 3, the washer 6 being a steel sheet, and one side of the washer 6 being welded to the adapter steel plate 2. In this embodiment, by setting the washer 6, the bolt 3 can be further tightened, and since the washer 6 is a steel sheet welded to the adapter steel plate 2, a more stable connection is achieved.

[0025] Example 2 As a further improvement on Embodiment 1, this embodiment provides a specific method for providing a limiting member, such as... Figure 2 As shown, further, the limiting components are two screws 7, which are threaded onto the adapter steel plate 2 and the column 4 respectively. The two screws 7 are located below the bolts 3 in the two connecting components, that is, below the keyholes. After connecting the bolts 3 to the adapter steel plate 2 and the column 4, the two screws 7 are then threaded between the adapter steel plate 2 and the column 4. This prevents the adapter steel plate 2 from moving up and down or deflecting, thus limiting its position and further ensuring a stable connection between the adapter steel plate 2 and the column 4.

[0026] In this embodiment, the other structures are the same as in embodiment 1, except that optimizations have been made to embodiment 1.

[0027] Example 3 As a further improvement on Embodiment 1, the adapter steel plate 2, the two connectors, and the limiting member form a set of connection structures. Two sets of connection structures are provided, distributed along the axial direction of the column 4. This embodiment differs from Embodiment 1, which is a single-point connection for the column 4. This embodiment is designed to accommodate a double-point connection for the column 4. Embodiment 1 is suitable for column 4 heights less than 4.2m, while this embodiment is suitable for column 4 heights between 4.2m and 6m. Specifically, for a double-point connection of the column 4, the limiting member only needs to be provided in the top connection structure.

[0028] Furthermore, the spacing between the transition steel plates 2 in the two sets of connection structures is 450mm-600mm, with the optimal spacing being 500mm. If the spacing between the two sets of connection structures is too large or too small, it will affect the subsequent installation work.

[0029] In this embodiment, the other structures are the same as in embodiment 1, except that optimizations have been made to embodiment 1.

[0030] The advantages of this invention are that, by using a transition steel plate and two connectors, two curtain wall transition pieces can be connected to the column. This is especially beneficial for small corner columns, as it allows for connection without penetrating the column or damaging its internal structure, and also avoids exposed bolts affecting aesthetics. In use, the ends of the two curtain wall transition pieces are first welded to the transition steel plate. Then, the welded integrated structure is connected to the column via the two connectors, thus achieving the connection between the two curtain wall transition pieces and the column. After connection, a limiting component prevents the transition steel plate from deflecting, further ensuring a stable connection between the two curtain wall transition pieces and the column.

[0031] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
