A prefabricated insulated building panel features a sheet of rigid thermally insulating material, an inner structural layer connected to one face of the insulating material, and an outer layer of cured composite cementitious material connected to an opposite second face of the rigid insulating material with a thickness allowing the cured composite cementitious layer to be supported at the insulating material by bonding action therewith. The panel also features channels at the interface between the composite cementitious outer layer and the insulating material formed by grooves in the second face of the insulating material extending to a periphery of the panel. These channels afford pressure equalization and moisture drainage capabilities to the panel.

Additionally, the inner structural layer comprises a layer of cured composite cementitious material bonded to the insulating material, which has a thickened edge portion along the periphery of the panel compared to strengthen the panel.

The present application relates to the technical field of engineering construction and provides a rebar, a device and a construction method for 3D-printing a concrete interlayer structure. The rebar at least comprises: a body in the form of a chain structure, comprising a plurality of sub-parts mutually spliced, wherein the body is adapted for being sandwiched between two adjacent upper and lower cement-based slurry layers; a rotatable joint arranged between two adjacent sub-parts in such a way that the two adjacent sub-parts are rotatably connected to each other; insertion members, wherein both sides of each of the sub-parts are provided with the insertion members extending away from the center of each of the sub-parts, wherein the insertion member on one side of each of the sub-parts is adapted for being inserted in an upper cement-based slurry layer, and the insertion member on an opposite side of each of the sub-parts is adapted for being inserted in a lower cement-based slurry layer. In summary, the rebar can simultaneously enhance the bearing capacity of the printed structure both in the horizontal direction and in the vertical direction, improve the overall connection strength of the printed structure, so that the building structure is not prone to damage or collapse, which is conducive to reducing any potential safety hazard.

Self-standing, thermally-insulating, noise-insulating, seismically-insulating, water-insulating, electromagnetic-insulating superstructure, whose overall internal volume is filled with rigid and lightweight granules, in which the dwelling rooms are immersed. The lightweight granules are spherical, porous or hollow, they have no binder and are scattered. A gas-tight skin clads all the outer surface of the superstructure's shell and the walls of the dwelling quarters. Gas-tight bay-frames of conical outer shape are embedded in the openings and bays. The entire volume, made up of the scattered granules, the plates, the bay-frames and the gas-tight skin, is under gas-vacuum. This gas-vacuum is lifetime-controlled by a vacuum pump which is installed in situ. The outer casing and the inner walls are braced by the volume of granules stiffened by atmospheric pressure. A plurality of ion-polarized layers, vaporized on overlay metallized polymer vacuum sheets, are inserted between the rigid plates and the gasproof skin.
