The size of the step can be 5 mm*5 mm, that is, the difference between the thickness of the edge of the outer surface of the decorative panel 11 and the thickness of other parts is 5 mm, and the length extending inward is also 5 mm. It is convenient to install adjacent curtain walls 1 using the curtain wall installation system of the present application.

[0054] Furthermore, all edges of the outer surface of the decorative panel 11 are step structures 111 , which facilitates installation between adjacent curtain walls 1 using a unified curtain wall installation system.

[0055] Furthermore, the decorative panel 11 is consistent in size with the back panel 13 and is larger than the thermal insulation layer 12, so that when the three are bonded together, the edges of the thermal insulation layer 12 are all located inside the edges of the decorative panel 11 and the back panel 13, forming a gap filled with sealant 14, which can be sealed with neutral silicone weather-resistant sealant, solving the problem of preventing the vacuum decompression panel from being punctured.

[0060] When in use, the mounting portion 32 extends to the side away from the wall 5, and the adjusting portion 31 of the adjusting member 3 is inserted into the adjusting groove 24 of the wall connecting member 2, and can move along the length direction of the adjusting groove 24, so that the position of the adjusting member 3 fixed on the wall connecting member 2 can be adjusted along the second direction. The present application uses a mechanical connection method to solve the problem of curtain wall falling off; compared with the traditional curtain wall system, it can save a large area of ​​keels to save construction period and cost; compared with the traditional curtain wall system, it saves structural thickness and increases the building use area.

[0061] Preferably, there may be a step structure between the adjusting portion 31 and the mounting portion 32 , that is, the adjusting portion 31 and the mounting portion 32 are not in the same plane along the thickness direction, so as to facilitate installation.

[0062] As attached Figure 5 As shown, the corner piece 4 can be made of aluminum alloy, and includes a slot portion 41 and a connecting portion 42 connected to each other, the slot portion 41 is used to install the curtain wall 1, the connecting portion 42 extends along the third direction, and is provided with a corner piece strip hole 43 extending along the third direction, and the third direction is a direction perpendicular to the wall 5. The connecting portion 42 of the corner piece 4 is connected to the mounting portion 32 of the adjusting member 3, and the distance between the corner piece 4 and the wall 5 can be adjusted through the corner piece strip hole 43, thereby adjusting the distance between the curtain wall 1 and the wall.

[0063] As attached Figure 7As shown, during the specific installation, the connecting portion 42 of the angle piece 4 corresponds to the mounting portion 32 of the adjusting member 3, and the connection between the angle piece 4 and the adjusting member 3 is achieved by arranging a bolt 33 in the angle piece strip hole 43 and threading the bolt 33 with the threaded hole 321 on the mounting portion 32 of the adjusting member 3.

[0064] Furthermore, a gasket 34 is provided between the bolt 33 and the angle piece 4 to improve the stability of the installation.

[0065] Furthermore, an isolation pad 7 is provided between the gasket 34 and the connecting portion 42 of the corner piece 4, and between the connecting portion 42 of the corner piece 4 and the mounting portion 32 of the adjusting member 3, to prevent the two metals from directly contacting each other and emitting noise, and to adjust small errors; the thermal conductivity of metal is high, and after adding an isolation pad between metals or between metals and the wall, a thermal bridge is formed, which effectively reduces heat conduction.

[0066] The installation system of the present application has a first direction along the vertical direction of the wall 5, a second direction along the horizontal direction of the wall 5, and a third direction perpendicular to the wall 5. During the construction process of installing the curtain wall 1, due to the presence of steel bars in the wall 5, there may be a deviation between the position of the anchor hole and the line-laying position, and the wall connecting member 2 and the wall connecting strip hole 26 are used to adjust the wall 5 up and down. When the flatness of the wall 5 does not meet the requirements, the adjustment member 3 is used to adjust the horizontal and left and right directions, and the angle strip hole 43 of the angle piece 4 in and out is used to adjust the in and out direction to ensure the installation flatness of the curtain wall. The coordinated installation of the wall connecting member 2, the adjustment member 3, and the angle piece 4 uses a chemical post-cut dual-function anchor bolt to solve the safety problem that the existing thermal insulation decorative integrated board adopts a combination of adhesive or adhesive anchoring, which is easy to fall off due to insufficient pull-out force. At the same time, the chemical post-cut dual-function anchor bolt has a single pull-out force damage value of up to 10KN on the brick wall. Considering the curtain wall load, it still meets the force calculation requirements, and can realize the installation of vacuum insulation thermal insulation decorative integrated board without keel, reduce the construction period, and save costs.

[0067] Further, such as Figure 3 As shown, the adjustment groove 24 of the wall connecting member 2 includes an inner groove 241 and an outer groove 242, the inner groove 241 is a circular groove, and the notch is connected to the outer groove 242, and the gap between the two side walls of the outer groove 242 gradually decreases from the outside to the inside; the adjustment part 31 of the adjustment member 3 has a circular plate 311 adapted to the circular groove of the inner groove 241, the adjustment part 31 of the adjustment member 3 can move in the inner groove 241, and can be slightly rotated, so as to realize the micro-rotation of the adjustment member 3 along the wall connecting member 2.

[0068] Furthermore, a mounting hole 221 connected to the inner groove 241 is provided on the first limiting portion 22 of the wall connecting member 2. After the second direction is adjusted and slightly rotated to the right position, a screw is provided in the mounting hole 221 to fix the circular plate 311 of the adjusting portion 31.

[0069] Furthermore, a tightening hole 251 is provided on the extension portion 25 of the wall connecting member 2 along the first direction. When in use, a tightening bolt 252 is threadedly connected in the tightening hole 251 to achieve fine-tuning tightening with the adjusting member 2 .

[0070] Further, such as Figure 5 , Figure 6 As shown, a step 44 adapted to the curtain wall 1 is provided in the groove of the slot portion 41 of the corner piece 4, and a first side wall 411 of the slot portion 41 close to the connecting portion 42 extends toward a side away from the plane of the connecting portion 42, and is provided with an exhaust hole 45 for exhausting air when installing the curtain wall 1 to improve the flatness of the installation.

[0071] Specifically, the slot portion 41 has a first side wall 411 and a second side wall 412, and the second side wall 412 is located at the end of the corner piece 4 away from the connecting portion 42. The second side wall 412 is adapted to the step structure 111 of the curtain wall 1. When the curtain wall 1 is installed, the second side wall 412 is clamped at the outer surface step structure 111 of the decorative panel 11 of the curtain wall 1, and the decorative panel 11, the thermal insulation layer 12, and the back plate 13 of the curtain wall 1 are clamped between the first side wall 411 and the second side wall 412, so as to facilitate the fixing of the curtain wall 1.
