The invention relates to an anti-counterfeiting transfer printing technology which comprises the following steps: preparing a laser plate; coating a layer of mold release agent or imaging paint on a PET base film; carrying out vacuum pumping on the PET base film and an aluminum material device in a vacuum plating evaporator; then heating the aluminum material and depositing gaseous aluminum particles on the surface of the moving PET base film and / or the surface of the mold release agent or the imaging paint; stamping an embossing pattern on the laser plate on a mold release agent layer or an imaging paint layer and / or an aluminum layer so as to make a holographic transfer film for transfer; bonding the holographic transfer film and backing paper together; separating the PET base film fromthe paper, wherein the stripped PET base film can be repeatedly used for a coated base film; and coating a layer of aqueous varnish on the surface of the transferred paint layer and / or the aluminum layer. The technology can combine an anti-counterfeiting printing technology with a transfer printing technology, and an aluminum plating layer transferred on the paper can be made to be thin, thereby saving the aluminum material; in addition, the base film used in transfer printing can be repeatedly utilized and does not pollute the environment.

The invention relates to an aluminum template which has higher use efficiency and saves more materials. The aluminum template comprises a panel and connection plates at the periphery of the inner side of the panel, wherein a plurality of vertical reinforcing ribs and transverse reinforcing ribs are arranged on the inner side of the panel, and the two ends of the vertical reinforcing ribs and the transverse reinforcing ribs are fixedly connected with the connection plates respectively; notches are formed in one sides of the transverse reinforcing ribs, which are contacted with the panel; the vertical reinforcing ribs are inserted into the notches. According to the aluminum template, a manner of arranging the reinforcing ribs vertically and transversely is adopted so that the panel with a template area of 0.5 square meters is divided into a plurality of small stresses faces, so that the template is not easy to deform and the strength and the bearing capability of the template are enhanced greatly; convex shoulder strip inner bolts are arranged on the connection plates for connection so that the occlusion of the templates is more tight and slurry is not easy to seep, and furthermore, the slurry is saved and a construction site is prevented from being polluted by the slurry; a pin sheet is set to be a radian plate so that the pin sheet is not easy to fall off, is convenient to mount and dismount and is convenient to pick up when falling down to the ground; the construction cost is reduced effectively to a certain extent.

The invention belongs to the technical field of building structures and relates to a bolt-assembled double-layer aluminum alloy latticed shell structure. The bolt-assembled double-layer aluminum alloy latticed shell structure comprises a plurality of H-type aluminum alloy bars. The H-type aluminum alloy bars on the upper layer are connected with the upper end of a vertical aluminum alloy circular web member through a bolt assembly joint on the upper layer, and the H-type aluminum alloy bars on the lower layer are connected with the lower end of the vertical aluminum alloy circular web member through a bolt assembly joint on the lower layer. Each bolt assembly joint comprises an upper cover plate, a lower cover plate, a center ribbed tube and a ribbed plate, wherein the ribbed plate is connected the center ribbed tube, and the center ribbed tube is connected with the upper cover plate and the lower cover plate through bolts. The upper flanges of the H-type aluminum alloy bars are connected with the upper cover plates of the bolt assembly joints through bolts, and the lower flanges of the H-type aluminum alloy bars are connected with the lower cover plates of the bolt assembly joints through bolts. Webs of the H-type aluminum alloy bars are connected with the ribbed plates of the bolt assembly joints through bolts. In this way, the bolt-assembled double-layer aluminum alloy latticed shell structure is formed. According to the bolt-assembled double-layer aluminum alloy latticed shell structure, the overall stability of a structural system and the utilization ratio of materials can be improved.
