Description

Technical Field

[0001] This utility model relates to an external wall settlement joint technology, and more particularly to a connection structure for external wall settlement joints, or a connection method for expansion joints, which helps to improve the aesthetics of external walls. Background Technology

[0002] In building structures, settlement joints or expansion joints are important structural measures used to mitigate structural deformation caused by uneven foundation settlement or temperature changes. Traditional methods for treating exterior wall settlement joints typically prioritize functionality, often using metal covers (such as aluminum alloy or stainless steel), rubber sealing strips, or asphalt-impregnated hemp fibers for covering or filling. While these methods can meet basic waterproofing, seepage prevention, and deformation adaptation requirements, they have significant drawbacks in terms of aesthetic harmony, specifically:

[0003] 1. Material and finish mismatch: Existing settlement joint covers are mostly standardized industrial products with a single material (such as a metallic finish), making it difficult to integrate with the texture, color, and grain of exterior wall finishes (such as imitation stone paint, cultured stone, glass curtain walls, or ceramic tiles). For example, the obvious color difference and reflectivity difference between metal covers and stone finishes create a visually disjointed effect, damaging the overall aesthetics of the building facade.

[0004] 2. Crude Joint Treatment: Traditional cover plates require caulking or rivet fixation after installation. The caulking agent color is difficult to match with the cover plate and wall surface, and long-term exposure can lead to caulking and discoloration, as well as warping of the cover plate edges, further exacerbating the aesthetic disharmony. Furthermore, uneven gaps often appear at the joint between the cover plate and the wall due to construction errors, affecting the flatness of the facade.

[0005] 3. Conflict between dynamic deformation and decorative surface: Settlement joints need to shift with building deformation. However, in existing technologies, the expansion joint design of the cover plate or sealing material is mostly exposed. Its mechanical structure and decorative surface material cannot deform synchronously, resulting in misalignment, cracking, or detachment of the expansion joint and the surrounding decorative surface.

[0006] It creates a clear "patch" effect.

[0007] While some improved products exist on the market, their durability, waterproofing, and simulation of complex decorative surfaces remain insufficient, and they cannot solve the problem of exposed joints caused by dynamic deformation. With increasing demands for architectural aesthetics, achieving an invisible and integrated design between settlement joints and exterior wall finishes has become a critical technical bottleneck that the industry urgently needs to overcome. Summary of the Invention

[0008] The purpose of this utility model is to provide a connection structure for the settlement joint of the exterior wall. Through structural improvement, sufficient deformation space can be reserved, and an exterior finish that matches the exterior wall can be provided to enhance the overall aesthetics of the exterior wall.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: a connection structure for an exterior wall settlement joint, including a mid-span structure spanning between two side walls. The mid-span structure is a steel frame structure, with one side being a fixed end fixedly connected to the corresponding side wall, and the other side being a free end fitting and overlapping with the corresponding side wall. The outer side of the mid-span structure is provided with a decorative line system, including vertical lines covering the mid-span structure and a connection structure for fixing the vertical lines. The connection line structure includes a base plate fixedly connected to both ends of the mid-span structure and a connecting support fixed to the vertical lines.

[0010] In the above technical solution, the mid-span structure includes left and right longitudinal uprights and several transverse cross-connectors. Each transverse cross-connector is L-shaped, with one end being the fixed end welded to the embedded part in the wall, and the other end extending to the other side wall and connecting to the corresponding longitudinal upright to form the free end. The transverse cross-connectors are spaced across the left and right longitudinal uprights to form a steel frame structure.

[0011] In the above technical solution, the decorative line system includes vertical lines and side wing decorative strips. The side wing decorative strips are distributed on the left and right sides of the vertical lines and are fixed to the connecting supports by stainless steel rivets. The side wing decorative strips are long aluminum alloy profiles. The side closer to the vertical lines is connected to the vertical lines by rivets, and the side closer to the wall is sealed with sealant.

[0012] A further technical solution is that the vertical lines in the decorative lines are formed by bending aluminum single panels, including a shaped surface and two side flanges. The two side flanges wrap around the two side connecting supports and are respectively riveted and fixed to the left and right side wing shaped strips.

[0013] In the above technical solution, the connecting support includes an L-shaped bent steel plate, a connecting back plate, and a horizontal positioning plate. One end of the L-shaped bent steel plate is connected to the decorative line system, and the other end is provided with an adjustment elongated hole corresponding to the base plate. The connecting back plate is located next to the adjustment elongated hole and together with the horizontal positioning plate forms an installation position. The base plate is inserted into the adjustment elongated hole and fixed to the connecting back plate by a limiting bolt. An adjusting stud passes through the horizontal positioning plate and abuts against the base plate.

[0014] In the above technical solution, a fireproof and heat-insulating layer is provided between the two side walls.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. The mid-span structure in this utility model is fixed on one side and free on the other. By fixing one end and flexibly adjusting the other, it can absorb structural deformation caused by uneven settlement or temperature changes of the two walls. Compared with the previous method of fixing both sides, it can better adapt to changes in the wall.

[0017] 2. Installing a decorative molding system on the outside of the mid-span structure serves two purposes: firstly, it provides protection for the inner mid-span structure, enhancing its waterproofness and durability; secondly, the decorative molding system can be selected to match the style and materials of the exterior wall design, achieving a unified, harmonious, and aesthetically pleasing exterior wall decoration effect.

[0018] 3. This utility model has a simple structure and is easy to implement. Attached Figure Description

The following will refer to the appendix... Figure 1-4The present invention will be described in detail with reference to the embodiments.

[0025] See Figure 1 As shown, a connection structure for an external wall settlement joint includes a mid-span structure 2 spanning between two side walls 1, and a fireproof and heat-insulating layer 3 is provided between the two side walls 1.

[0026] The mid-span structure 2 is a steel frame structure. One side (right) is a fixed end 4, which is fixedly connected to the corresponding side wall 1, and the other side (left) is a free end 5, which is fitted and overlapped with the corresponding side wall 1. The outer side of the mid-span structure 2 is provided with a decorative line system, including vertical lines 6 covering the mid-span structure 2, and a connecting structure for fixing the vertical lines 6. The connecting line structure includes a base plate 7 fixedly connected to both ends of the mid-span structure 2 and a connecting support 8 fixed to the vertical lines 6.

[0027] like Figure 3 , 4 As shown, the mid-span structure 2 includes left and right longitudinal uprights 9 and several transverse cross-connectors 10. Each transverse cross-connector 10 is L-shaped, with the left end being the fixed end 4 welded and fixed to the embedded part 11 in the wall, and the right end extending to the corresponding side wall and connecting to the right longitudinal upright 9 to form the free end 5 (not connected to the wall). The transverse cross-connectors 10 are spaced across the left and right longitudinal uprights 9 to form a steel frame structure.

[0028] like Figure 1 As shown, the decorative line system includes vertical lines 6 and side wing decorative strips 12. The side wing decorative strips 12 are distributed on the left and right sides of the vertical lines and are fixed to the connecting supports 8 by stainless steel rivets 13. The side wing decorative strips 12 are long aluminum alloy profiles. The side closer to the vertical line 6 is connected to the vertical line 6 by rivets 14, and the side closer to the wall 1 is sealed with sealant 15. Different line structures, materials, and colors are selected according to the exterior wall design requirements to match the curtain wall. This embodiment only presents one line structure as an example.

[0029] The vertical line 6 in the decorative lines is formed by bending aluminum single panels, including a shaped surface and two side flanges. The two side flanges wrap around the two side connecting supports 8 and are respectively riveted and fixed to the left and right side wing shaped strips 12, providing shielding and concealment for the mid-span structure 2.

[0030] like Figure 2As shown, the connecting support 8 includes an L-shaped bent steel plate 16, a connecting back plate 17, and a horizontal positioning plate 18. One end of the L-shaped bent steel plate 16 is connected to the side wing shaping strip 12, and the other end is provided with an adjusting elongated hole 21 corresponding to the base plate 7. The two base plates 7 are welded and fixed to the left and right longitudinal uprights 9. The connecting back plate 17 is set beside the adjusting elongated hole 21, forming an installation position together with the horizontal positioning plate 18 (L-shaped bent steel plate in the Y direction + connecting back plate in the X direction + horizontal positioning plate in the Z direction). The base plate 7 is inserted into the adjusting elongated hole 21, having an adjustment range in the Z direction. It is fixed to the connecting back plate 17 by a limiting bolt 19, and the adjusting stud 20 passes through the horizontal positioning plate 18 and abuts against the base plate 7, limiting the Z direction position of the base plate 7. The above X, Y, and Z directions are all based on Figure 1 , 2 The view direction.

[0031] This utility model utilizes a fixed connection on one side of the mid-span structure 2 to the wall 1, while the other side is not fixedly connected to the wall. Compared with the previous connection method where both sides are fixed, this application has a greater ability to absorb the deformation of the wall caused by factors such as settlement in terms of function. In terms of decoration, the decorative line system can match the curtain wall itself in terms of material and shape, without being affected by functionality, thereby achieving the requirements of invisible and integrated design.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
