[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0012] The present embodiment discloses an integrated vacuum insulation decorative reverse wall panel, which mainly includes an integrated decorative insulation panel. After pouring concrete 1 on the integrated decorative insulation panel, an integrated vacuum insulation decorative reverse wall panel is formed. The integrated decorative insulation panel is composed of a decorative panel 5 and a vacuum insulation panel 3. In the present embodiment, the decorative panel 5 is made of calcium silicate board, and the decorative panel 5 is a whole board. The size of the vacuum insulation panel 3 is smaller than that of the decorative panel 5. A plurality of vacuum insulation panels 3 are laid flat and bonded on the back of the decorative panel 5. The plurality of vacuum insulation panels 3 are laid vertically and horizontally at a certain distance, such as Figure 1 As shown, the area reserved between adjacent vacuum insulation panels 3 is the adjustment band 7 in this embodiment. The adjustment band 7 facilitates the adjustment of the installation position of vacuum insulation panels 3 of different sizes. The width design of the horizontal adjustment band and the vertical adjustment band can be adjusted according to the size of the vacuum insulation panel 3 used. If the vacuum insulation panel 3 is square, the width of the horizontal and vertical adjustment bands can be designed to be consistent; if the vacuum insulation panel 3 is rectangular, the width of the horizontal and vertical adjustment bands can be different.

[0013] As mentioned above, the back of the decorative panel 5 corresponding to the position of the adjustment strip 7 needs to be pre-opened with a back bolt hole. After the vacuum insulation panel 3 and the decorative panel 5 are bonded, a thermal insulation back bolt 2 is installed in each back bolt hole. Figure 2 and Figure 3 As shown, the thermal insulation back bolt 2 in this embodiment is mainly assembled by a back bolt head 21, a nylon sleeve 22, a gasket 23 and a screw rod 24. The connecting end of the back bolt head 21 and the nylon sleeve 22 is provided with an external thread, the inside of the nylon sleeve 22 is provided with an internal thread, and the inner wall of the circular hole of the gasket is provided with an internal thread. When installing the thermal insulation back bolt 2, first screw the connecting end of the back bolt head 21 and the decorative panel 5 into the back bolt hole, then connect the nylon sleeve 22 with the external thread end of the back bolt head 21, then screw the screw rod 24 into the other end of the nylon sleeve 22, and finally install the gasket 23 on the top of the screw rod 24. The height of the screw rod 24 is higher than the top surface height of the vacuum insulation panel 3, so that the screw rod 24 and the gasket 23 can be embedded in the poured concrete 1.

[0014] After the installation of the thermal insulation back bolt 2 is completed, the aerogel roll felt 4 is filled into the adjustment belt 7. Other materials that are easy to cut and have thermal insulation effects can also be used to replace the aerogel roll felt 4. Then, the outer surface of the aerogel roll felt 4 is covered with a self-adhesive air-insulating film 6 to complete the thermal bridge blocking treatment. Next, the steel cage is placed on the top of the vacuum insulation panel 3, and finally concrete 1 is poured on the top of the vacuum insulation panel 3. After solidification and demoulding, the integrated vacuum insulation decorative reverse wall panel of this embodiment is completed.

[0015] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
