Description

Technical Field

[0001] This utility model relates to the field of building exterior window construction technology, and in particular to a window frame expansion joint structure. Background Technology

[0002] Currently, during the installation of window frames, expansion joints are usually installed at the connection between the window frame and the wall. This is because buildings are affected by various factors during use, and temperature changes can cause building materials to expand and contract. Without expansion joints, it is easy for the window frame or wall to crack and deform.

[0003] Existing window frame expansion joint structures use ordinary sealant or foam strips to fill the expansion joints, but they often have the following shortcomings;

[0004] First, ordinary sealant or foam strips have poor durability. After being exposed to wind, sun and temperature changes for a long time, they are prone to aging and cracking, which affects the normal use of expansion joints.

[0005] Secondly, the construction of some expansion joints is quite complex during installation, requiring a lot of time and effort. This not only increases construction costs but also makes it difficult to guarantee installation quality. If installation errors occur, subsequent repairs and rectifications are also quite complicated.

[0006] Based on this, the present invention proposes a window frame expansion joint structure. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model proposes a window frame expansion joint structure, which not only improves construction and installation efficiency and quality but also reduces costs and effectively prevents window frame deformation.

[0008] The technical solution to achieve the purpose of this utility model is as follows: a window frame expansion joint structure, including two pairs of fixing plates, with a window frame one and a window frame two fixedly installed between each pair of fixing plates, and multiple sets of rolling steel balls rolled on the opposite side of each fixing plate and the window frame one and the window frame two slidingly engaged.

[0009] In some embodiments, a pair of limiting grooves are provided on opposite sides of window frame one and window frame two, and a pair of limiting plates are fixedly installed on the side of window frame one and window frame two near the limiting grooves. A decorative plate is slidably installed between window frame one and window frame two, and the decorative plate slides in cooperation with the limiting plates and limiting grooves.

[0010] Compared with existing technologies, the significant advantages of this invention are:

[0011] Firstly, this utility model utilizes rolling steel balls and decorative panels to enable the two window frames to achieve a certain displacement, thereby significantly offsetting the deformation of the window frames caused by temperature differences in the wall structure, which affects the normal use of the windows. Furthermore, the decorative panels not only allow for the displacement of window frame one and window frame two, but also seal the intersection of the window frames, thereby improving the overall neatness and aesthetics of the frame.

[0012] Secondly, this utility model uses two window frames and decorative panels to create relative displacement, thereby offsetting the changes in the window frame structure caused by wall deformation. It is not only convenient to construct, but also has high durability and will not affect the stability of the building structure.

[0013] This addresses the problems of existing expansion joint structures that use ordinary sealant or foam strips for filling, which have poor durability and are prone to aging and cracking after prolonged exposure to wind, sun, and temperature changes, affecting the normal use of the expansion joints; secondly, some expansion joint structures are quite complex to install, requiring a lot of time and effort, which not only increases construction costs but also makes it difficult to guarantee installation quality. Once an installation error occurs, subsequent maintenance and rectification work is also quite cumbersome. Attached Figure Description

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This utility model provides an improved window frame expansion joint structure. The technical solution of this utility model is as follows:

[0022] like Figures 1-3 As shown, a window frame expansion joint structure includes two pairs of fixing plates 1. Window frame one 3 and window frame two 4 are fixedly installed between each pair of fixing plates 1. Multiple sets of rolling steel balls 2 are slidably installed on the opposite side of each fixing plate 1 and window frame one 3 and window frame two 4. Window frame one 3 and window frame two 4 are slidably engaged. The window frame one 3 and window frame two 4 and the fixing plates 1 can provide support for the installation of the rolling steel balls 2. By using the sliding installation method, it can effectively adapt to the deformation of the structural wall caused by factors such as temperature difference, thereby avoiding deformation of the window frame as a whole, which would affect the normal use of the window.

[0023] Furthermore, a pair of limiting grooves 7 are provided on opposite sides of window frame 3 and window frame 4. A pair of limiting plates 5 are fixedly installed on the side of window frame 3 and window frame 4 near the limiting grooves 7. A decorative plate 6 is slidably installed between window frame 3 and window frame 4. The decorative plate 6 slides in cooperation with the limiting plates 5 and the limiting grooves 7. The decorative plate 6 can beautify the intersection of window frame 3 and window frame 4. The limiting grooves 7 can ensure that the decorative plate 6 slides inside window frame 3 and window frame 4. This ensures that when window frame 3 and window frame 4 are displaced by external factors, the decorative plate 6 can move in coordination with window frame 3 and window frame 4, thus ensuring that window frame 3 and window frame 4 can adapt to different degrees of displacement caused by the deformation of the wall structure.

[0024] The specific working method is as follows: Rolling steel balls 2 are installed at equal intervals on the side walls of the fixing plate 1, window frame 3, and window frame 4. The fixing plate 1 is fixedly connected to window frame 3 and window frame 4. The decorative plate 6 is installed inside window frame 3 and window frame 4 through the limiting groove 7. After installation, window frame 4 is fixed to one end of the expansion joint, and window frame 3 is fixedly installed to the structural frame. The installation is now complete. When the wall structure deforms due to factors such as temperature difference, window frame 3 and window frame 4 can move, thereby offsetting the damage to the overall window frame caused by the deformation of the structural wall and avoiding affecting the normal use of the window.

[0025] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
