Description

Technical Field

[0001] The utility model relates to an external wall panel, in particular to a prefabricated sandwich thermal insulation lightweight external wall panel, belonging to the technical field of building accessories. Background Art

[0002] External wall panels have been widely used in the field of prefabricated buildings. External wall panels need to have thermal insulation capabilities, and in many cases they should also have the ability to be suspended and installed. Therefore, in order to ensure the structural strength of the external wall panels, combined with their thermal insulation capabilities, their weight is generally large; and excessively heavy wall panels will increase logistics and transportation costs; as well as the danger of high-altitude operations. At the same time, in order to have thermal insulation capabilities, existing external wall panels usually add multiple layers of composite panels to the wall panels, which makes it more difficult to reduce the weight of the external wall panels.

[0003] Therefore, further improvement is needed. Utility Model Content

[0007] Furthermore, the wall panel shell is made of metal color steel plate; the upper and lower ends of the installation and fixing block are provided with fixing flanges; and the fixing flanges are provided with fixing screw holes.

[0008] Furthermore, matching screw holes are provided on the upper and lower sides of the mounting strip hole; the mounting fixing block is inserted into the mounting strip hole; the fixing flange covers the upper and lower sides of the mounting strip hole; the fixing screw hole and the matching screw hole are arranged relative to each other and fixed by bolts.

[0009] Furthermore, the mounting bracket comprises at least two; the mounting bracket is transversely connected between the two mounting fixing blocks; and the mounting fixing block is provided with a through hole relative to the mounting bracket.

[0010] Furthermore, the mounting bracket passes through a through hole; the end of the mounting bracket is located on the outside of the mounting fixing block; the external fastener is L-shaped; the external fastener includes a horizontal plate parallel to the mounting fixing block; and a vertical plate is arranged on the horizontal plate.

[0011] Furthermore, the horizontal plate is connected to the mounting bracket; the vertical plate is provided with a fixed mounting hole; and the vertical plate is fitted to the beam column.

[0012] Furthermore, the thermal insulation filler is kapok aerogel.

[0013] The utility model has the following beneficial effects: a wall panel shell is used as the main body of the exterior wall panel, and a heat-insulating chamber is provided inside the wall panel, and is filled with heat-insulating fillers as heat-insulating fillers; the wall panel shell is hollowed out to improve its lightness; at the same time, mounting strip holes are opened on both sides of the wall panel shell, and mounting fixing blocks are arranged in the mounting strip holes, and a mounting bracket is connected between the two mounting fixing blocks, and a hanging beam is arranged outside the mounting bracket; in this way, the wall panel shell only uses the mounting fixing blocks for load-bearing, and the mounting fixing blocks themselves are necessary components for sealing the wall panel shell, so there is no need to use additional connecting parts to connect the wall panel shell, which greatly reduces the overall weight of the wall panel shell.
