[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-5 The present invention will describe the above technical solution in detail through the following embodiments: The decorative curtain wall in this embodiment uses an installation and fixing structure, such as... Figure 1 and Figure 2 The structure shown is suitable for quick assembly and disassembly of curtain wall unit panels 5. Each component has strong recyclability. Curtain wall unit panels 5 include, but are not limited to, insulation boards, aesthetic decorative boards, tempered glass, etc., as the structure of the curtain wall.

[0021] Specifically, in order to provide a fixed installation foundation and avoid the problem of damaging the foundation by repeatedly driving expansion bolts to install the corresponding curtain wall panels as in traditional construction, this embodiment installs an embedding unit 1 on the curtain wall foundation, including an embedding frame 11 pre-embedded in the curtain wall foundation, and a centering block 13 and a side block 12 respectively provided with external structures at the center and both sides of the outer end of the embedding frame 11.

[0022] like Figures 1-3 The structure shown has a bolt head slot 102 and a limiting slot 103 that are provided from the inside to the outside on the central locking block 13, and a first side slot 101 is provided in the side locking block 12; in this embodiment, a guide groove 104 is provided between the central locking block 13 and the side locking block 12, and a stop plate 7 is slidably installed in the guide groove 104 by a horizontally installed guide bolt 8.

[0023] An expansion compression sleeve 6 is fitted onto each of the multiple fastening bolts 3, and a pressure plate 2 is installed on the fastening bolts 3 and the outside of the expansion compression sleeve 6 by means of a nut. In the embodiment, at least two fastening bolts 3 are provided to ensure that the pressure plate 2 does not rotate or shift. Then, when the nut is tightened, the expansion compression sleeve 6 is squeezed and expanded to both sides and clamped to the side of the curtain wall unit panel 5 by the abutment plate 7.

[0024] Meanwhile, in order to further improve the stability of clamping, this embodiment provides a second side groove 202 for inserting rubber sealing strips 4 on both sides of the inner side of the pressure plate 2, and also inserts rubber sealing strips 4 into the first side groove 101. Therefore, a C-shaped wrapping clamping surface can be formed at the outer edge of the curtain wall unit panel 5 during the clamping process, so as to quickly complete the sealing and fixing, and facilitate the subsequent disassembly and replacement of the curtain wall unit panel 5.

[0025] In this embodiment, to obtain reliable deformation capability, an expansion compression sleeve 6 is provided, including a frame sleeve 61 fitted onto the fastening bolt 3. Anti-detachment blocks 62 and limiting blocks 63 are respectively connected to the inner and outer ends of the frame sleeve 61. A limiting groove 201 for preventing the limiting block 63 from derailing is provided in the middle of the inner side of the pressure plate 2. The anti-detachment block 62 is engaged in the limiting groove 103, and... Figure 5 As shown, an extension bending groove 611 is provided in the inner frame wall of the frame sleeve 61, which enables the sleeve 6 to undergo external expansion and deformation based on the extension bending groove 611 when it is compressed and expanded.

[0026] Similarly, in order to better wrap and hold the side of the curtain wall unit panel 5, clamping blocks 64 are provided on both sides of the frame sleeve 61. A buffer deformation cavity 642 is provided in the middle of the clamping block 64. When squeezed outward, the rubber blade 641 is forced to be in a centered and contracted state, thereby increasing the force-bearing area and pushing the outer abutment plate 7, improving the subsequent clamping stability and reliability.

[0027] The resisting plate 7 is arranged between the curtain wall unit plate 5 and the expansion extrusion sleeve 6, in order to prevent the curtain wall unit plate 5 from falling under the action of gravity, the resisting plate 7 is arranged in the form of a steel profile frame, and a rectangular clamping groove is arranged on the side of the curtain wall unit plate 5, so that the curtain wall unit plate 5 can be clamped in the groove wall on both sides, in order to avoid hard contact and damage to the curtain wall unit plate 5, a rubber lining is arranged on the inner wall of the clamping groove.

[0028] The protrusions 21 are arranged at the two ends of the outer edge of the pressing plate 2, when the tightening of the bolts 3 is completed, the exposed bolts affect the appearance and external protection, therefore, the packaging cover 9 is clamped on the outer part of the pressing plate 2, as shown in the structure, the U-shaped packaging cover 9 is clamped on the protrusions 21 through the insertion of the card slot 901, so as to complete the packaging protection; when the curtain wall unit plate 5 is replaced and maintained subsequently, the tightening of the bolts 3 can be released only by disassembling the packaging cover 9, and each part is easy to replace, and the operation is simple and reliable.

[0030] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.​
