Abstract
Description
Technical Field
[0001] This utility model relates to the field of decoration technology, and in particular to a window sill end closing connection structure. Background Technology
[0002] In architectural decoration projects, the finishing treatment of window sill ends is a crucial aspect of ensuring both the building's aesthetics and functionality. Existing window sill end finishing structures typically employ simple methods such as filling with sealant or directly fixing decorative strips. However, sealant is prone to aging and cracking over long-term use, leading to rainwater leakage and affecting the window sill's waterproofing performance. Directly fixing decorative strips is often insecure, easily loosening and falling off, affecting not only aesthetics but also posing safety hazards. Furthermore, it is difficult to adapt to window sills of different sizes and materials. Therefore, we propose a new window sill end finishing connection structure. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a window sill end-sealing connection structure. This utility model solves the problems of existing window sill end-sealing structures that typically use simple sealant filling or direct fixing of decorative strips. These methods often result in sealant aging and cracking over long-term use, leading to rainwater leakage and affecting the window sill's waterproof performance. Furthermore, direct fixing of decorative strips is often insecure, prone to loosening and detachment, affecting aesthetics, posing safety hazards, and being unsuitable for window sills of different sizes and materials.
[0004] This utility model discloses a window sill end-closing connection structure, including a window sill wall, a pad layer on the top of the window sill wall, a stone veneer on the top of the pad layer, a connecting plate on the side of the pad layer away from the window sill wall, a fixed plate fixedly connected to the lower part of the connecting plate away from the pad layer, a fixed plate fixedly connected to a side plate on the side of the fixed plate away from the connecting plate, an upwardly inclined protrusion on the upper part of the side plate away from the fixed plate, a plurality of equidistant positioning blocks on the side of the connecting plate near the pad layer, and positioning grooves matching the positioning blocks on the pad layer.
[0005] In the above scheme, the cross-section of the positioning block is trapezoidal.
[0006] In the above scheme, the positioning block has serrated grooves on both sides.
[0007] In the above scheme, the padding layer is EPDM rubber.
[0008] In the above scheme, the side plate away from the fixed plate is provided with a putty leveling layer.
[0009] In the above scheme, the protrusion is provided with a serrated groove on the side away from the fixing plate.
[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a window sill end finishing connection structure. The overall structure of the connecting plate, fixing plate, side plate, protrusion, and positioning block has strong overall strength. The positioning block is inserted into the positioning groove. Through the mutual cooperation between the positioning block and the positioning groove, the connecting plate and the padding layer can be stably connected. The inner layer of the putty leveling layer is flush with the side of the side plate away from the window sill wall, and the outer layer of the putty leveling layer is flush with the end of the protrusion away from the side plate. The serrated groove increases the contact area between the protrusion and the putty leveling layer, thus facilitating the coverage of the putty leveling layer. This connection structure is simple, has good concealment, and high installation stability, which can effectively avoid aging and cracking, and improve the service life of the window sill end finishing.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0016] like Figure 1-2As shown, this utility model is a window sill end-receiving connection structure, including a window sill wall 1, a pad 2 on the top of the window sill wall 1, a stone veneer 3 on the top of the pad 2, a connecting plate 4 on the side of the pad 2 away from the window sill wall 1, a fixing plate 5 fixedly connected to the lower part of the connecting plate 4 away from the pad 2, and a side plate 6 fixedly connected to the side plate 5 away from the connecting plate 4. An upwardly inclined protrusion 7 is provided on the upper part of the side plate 6 away from the fixing plate 5. The connecting plate 4, fixing plate 5, side plate 6, protrusion 7, and positioning block 8 are an integral structure, thereby effectively ensuring the overall structural strength of the connecting plate 4, fixing plate 5, side plate 6, protrusion 7, and positioning block 8. Multiple positioning blocks 8 are arranged at equal intervals on the side of the connecting plate 4 near the pad 2. The pad 2 has a positioning groove 9 that matches the positioning block 8. The positioning block 8 is inserted into the positioning groove 9. Through the mutual cooperation between the positioning block 8 and the positioning groove 9, the connecting plate 4 and the pad 2 can be stably connected.
[0017] The positioning block 8 has a trapezoidal cross-section, and the trapezoidal structure of the positioning block 8 allows it to be stably engaged inside the positioning groove 9.
[0018] The positioning block 8 has serrated grooves on both sides, which effectively increases the friction between the side wall of the positioning block 8 and the inner wall of the positioning groove 9.
[0019] The padding layer 2 is made of EPDM rubber.
[0020] The side panel 6 is provided with a putty leveling layer 10 on the side away from the fixed plate 5. The putty leveling layer 10 has two layers. The inner layer of the putty leveling layer 10 is flush with the side panel 6 away from the window sill wall 1, and the outer layer of the putty leveling layer 10 is flush with the end of the protrusion 7 away from the side panel 6.
[0021] The protrusion 7 has a serrated groove on the side away from the fixing plate 5. The serrated groove increases the contact area between the protrusion 7 and the putty leveling layer 10, making it easier to cover the putty leveling layer 10.
[0022] Specifically, in this utility model, the connecting plate 4, fixing plate 5, side plate 6, protrusion 7, and positioning block 8 are integrated into one structure, which effectively ensures the overall structural strength of the connecting plate 4, fixing plate 5, side plate 6, protrusion 7, and positioning block 8. The positioning block 8 is inserted into the positioning groove 9. Through the cooperation between the positioning block 8 and the positioning groove 9, the connecting plate 4 and the padding layer 2 can be stably connected. The inner layer of the putty leveling layer 10 is flush with the side of the side plate 6 away from the window sill wall 1, and the outer layer of the putty leveling layer 10 is flush with the end of the protrusion 7 away from the side plate 6. The serrated groove increases the contact area between the protrusion 7 and the putty leveling layer 10, thus making it easier to cover the putty leveling layer 10.
[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
