Description

Technical Field

[0001] The utility model relates to the field of construction, and particularly relates to an integral vacuum insulation decorative reverse casting wall panel. Background Technique

[0002] As a super high-performance decorative and energy-saving integrated material, the vacuum insulation decorative integrated board has been widely used. In the construction of building facades, the bonding and anchoring process is mostly adopted, that is, the vacuum insulation board and the decorative panel are bonded into an integral structure. Usually, the size of the vacuum insulation board is the same as that of the decorative panel. The vacuum insulation board cannot be freely cut, otherwise its insulation performance will be affected. Therefore, special sizes need to be completely customized, and the cost is often high when there are many modules. Content of the Utility Model

[0003] The utility model discloses an integral vacuum insulation decorative reverse casting wall panel, which combines a large-size decorative panel and multiple small-size vacuum insulation boards, and presets an adjustment band to adapt to vacuum insulation boards of different sizes, and also facilitates free cutting of the combined integral board according to size requirements, effectively improving the problem of module customization of the vacuum insulation board.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] An integral vacuum insulation decorative reverse casting wall panel, comprising a decorative panel and multiple vacuum insulation boards laid and bonded on the back surface of the decorative panel. The size of a single vacuum insulation board is smaller than that of the decorative panel, and there is a spacing distance between adjacent vacuum insulation boards. The area where the spacing distance is located forms an adjustment band. Back bolt holes are opened at the back surface of the decorative panel at the adjustment band, and heat-insulating back bolts are installed in the back bolt holes. Aerogel felt rolls are filled in the adjustment band, and a self-adhesive gas barrier film is covered on the outer surface of the aerogel felt rolls. A steel reinforcement cage is erected on the top of the vacuum insulation board and then concrete is poured.

[0006] Further, the decorative panel adopts a calcium silicate board.

[0007] Further, the heat-insulating back bolt comprises a back bolt head, a nylon sleeve, a gasket and a screw rod. The back bolt head is screwed into the back bolt hole of the decorative panel. One end of the back bolt head is threadedly connected with one end of the nylon sleeve with internal threads. One end of the screw rod is threadedly connected with the other end of the nylon sleeve. The other end of the screw rod is threadedly connected with the gasket with internal threads. A part of the screw rod and the gasket are embedded inside the concrete.

[0008] Further, the decorative panel in a single integral vacuum insulation decorative reverse casting wall panel is composed of a whole board, and the width of the vertical adjustment band on the back surface of the whole decorative panel is the same as or different from the width of the horizontal adjustment band.

[0009] The integrally formed vacuum insulation decorative reverse-cast wall panel designed by the present utility model uses a large-sized single-piece decorative panel as the outer decorative panel material. Multiple small-sized vacuum insulation panels are adhesively bonded to the inner side of the decorative panel for heat insulation. A adjustment band is reserved on the back of the decorative panel to accommodate vacuum insulation panels of different sizes. In the adjustment band, a back-bolt type method is used in cooperation with the installation of heat-insulating back bolts, and a material that is easy to cut is filled in the adjustment band for caulking treatment. The design of the adjustment band not only facilitates the installation and adjustment of vacuum insulation panels of different sizes, but also facilitates free cutting along the adjustment band according to the designed size of a single reverse-cast wall panel into the required size. The reverse-cast wall panel designed by the present utility model effectively improves the problem of modular customization of vacuum insulation panels and effectively conducts heat bridge blocking settings.

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.

[0016] This embodiment discloses an integrally formed vacuum insulation decorative reverse-cast wall panel, which mainly includes a decorative and heat-insulating integrated board. After pouring concrete 1 on the decorative and heat-insulating integrated board, an integrally formed vacuum insulation decorative reverse-cast wall panel is formed. Among them, the decorative and heat-insulating integrated board is composed of a decorative panel 5 and a vacuum insulation panel 3. In this embodiment, the decorative panel 5 uses a calcium silicate board, and the decorative panel 5 is composed of a single piece of board. The size of the vacuum insulation panel 3 is smaller than that of the decorative panel 5. Multiple vacuum insulation panels 3 are laid flat and adhesively bonded to the back of the decorative panel 5. Multiple vacuum insulation panels 3 are respectively laid at a certain distance vertically and horizontally, such as Figure 1As shown, the area left between adjacent vacuum insulation panels 3 is the adjustment band 7 in this embodiment. The adjustment band 7 facilitates the adjustment of the installation positions of vacuum insulation panels 3 of different sizes. For the width design of the horizontal and vertical adjustment bands, it can be adjusted according to the size of the vacuum insulation panel 3 used. If the vacuum insulation panel 3 is square, the widths of the horizontal and vertical adjustment bands can be designed to be the same; if the vacuum insulation panel 3 is rectangular, the widths of the horizontal and vertical adjustment bands can be different.

[0017] Continuing from the above, back bolt holes need to be pre-drilled on the back of the decorative panel 5 corresponding to the position of the adjustment band 7. After the bonding of the vacuum insulation panel 3 and the decorative panel 5 is completed, a heat-insulating back bolt 2 is installed in each back bolt hole. As Figure 2 and Figure 3 shown, the heat-insulating 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 connection 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 round hole of the gasket is provided with an internal thread. When installing the heat-insulating back bolt 2, first screw the connection end of the back bolt head 21 into the back bolt hole of the decorative panel 5, then connect the nylon sleeve 22 to 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 into the cast concrete 1.

[0018] After the installation of the heat-insulating back bolt 2 is completed, aerogel felt rolls 4 are filled into the adjustment band 7. Other materials that are easy to cut and have heat-insulating effects can also be used to replace the aerogel felt rolls 4. Then, a self-adhesive gas barrier film 6 is used to cover the outer surface of the aerogel felt rolls 4, thereby completing the blocking treatment of the heat bridge. Next, the steel reinforcement cage is placed on the top of the vacuum insulation panel 3. Finally, concrete 1 is poured on the top of the vacuum insulation panel 3. After curing and demolding, the integral vacuum insulation decorative reverse casting wall panel of this embodiment is completed.

[0019] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
