[0017] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structures and implementation methods. Therefore, the following specific implementation methods and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.
[0018] Figure 1 The schematic diagram shows the assembly structure of a new type of metal frameless curtain wall. Figure 1 As shown, it includes a fixing notch reserved on the structure 1 and a glass piece 2 to be fixed. A rubber strip 3 is fixed in the fixing notch, and a first notch 5 and a second notch 6 are opened on the rubber strip 3. The glass piece 2 is embedded in the first notch 5 and a filler strip 4 is inserted into the second notch 6 for fixing. The hardness of the filler strip 4 is higher than that of the rubber strip 3. By pressing the filler strip 4 with a higher hardness into the second notch 6 of the rubber strip 3, the pressing process is smooth, which can prevent the deformation of the rubber strip 3 to a certain extent, and ensure the stable fixation of the glass piece 2 on the structure 1. In actual application, the design hardness of the rubber strip 3 is 70N / mm2 The design hardness of the fillet 4 is 85N / mm 2 .
[0019] Figure 2 The cross-sectional structure of the rubber strip is schematically shown. The aforementioned rubber strip 3 (such as Figure 2 The edge of the embedded section 10 embedded in the fixed notch is fixed with a plurality of sawtooth pieces 11, and the width of the embedded section 10 is 3-4mm greater than the width of the fixed notch, so that the rubber strip 3 is firmly fixed, and the airtightness and waterproofness are improved. Before installation, the outer side of the sawtooth piece 11 of the rubber strip 3 needs to be convexly molded with sealant and then pressed into the fixed notch, which is beneficial to airtightness and waterproofness. The edge of the rubber strip 3 facing the side of the structure 1 is provided with a concave blade 12, and the concave blade 12 can make the rubber strip 3 fit closely with the surface of the structure 1, further improving the airtightness and waterproofness.
[0020] Figure 3 The schematic diagram shows the cross-sectional structure of the fillet, combined with Figure 2 as well as Figure 3 The rubber strip 3 is described in detail. A first notch 5 and a second notch 6 are provided on the rubber strip 3. The first notch 5 is provided in the middle area of the rubber strip 3. A concave blade 7 is provided at the entrance of the first notch 5. The second notch 6 is provided based on at least one side of the first notch 5. A concave arc section 8 is provided near the entrance of the second notch 6. A convex section 9 is provided on the insert 4. The convex section 9 fits with the concave arc section 8 to ensure the fit between the insert 4 and the rubber strip 3. When the rubber strip 3 is installed, the outer side of the rubber strip 3 is pressed down and the glass piece 2 is installed in the first notch 5. Then, the insert 4 is pressed into the second notch 6, so that the concave blade 7 at the entrance of the first notch 5 fits tightly with the glass piece 2. While fixing the glass piece 2, it also plays a sealing role. The convex section 9 on the insert 4 is stuck in the concave arc on the second notch 6, so that the insert 4 will not fall off.
[0021] In actual application, the glass piece 2 can be fixed by applying multiple adhesive strips 3 and filler strips 4 on the structure 1, which can effectively disperse the gravity load and lateral wind load of the glass piece 2, ensure the stability of the glass piece 2 fixed on the structure 1, and thus ensure the decorative effect of the curtain wall. Furthermore, the aforementioned adhesive strips 3 can be fixedly set at the stress point of the glass piece on the structure, and a polygonal structure is formed by multiple adhesive strips 3 to complete the fixation of the glass piece 2, enhance the bearing performance of the adhesive strips 3 on the glass piece 2, and ensure the stability of the curtain wall structure.
[0022] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
