A special mold for the production of one-time molding decorative thermal insulation externally pasted blocks

Abstract

The invention discloses a dedicated mold for producing one-shot formed decorative thermal-insulating externally-pasted bricks. The dedicated mold is characterized by comprising an upper mold head 1, a lower mold box flat plate 2, two short outer box plates 3, two short inner partition plates 4, two long outer box plates 5, long inner partition plates 6 and a plurality of tongue-shaped bosses 7. The two short outer box plates 3 and the two long outer box plates 5 form a rectangular framework, wherein the upper portion of the inner side of each short outer box plate 3 is of a boss shape, and the upper portion of the inner side of each long outer box plate 5 is in the shape of a boss which is evenly provided with the tongue-shaped bosses 7. The long inner partition plates 6 are located at the centers of the two long outer box plates 5 and parallel to each other. The two short inner partition plates 4 are located between the two short outer box plates 3 and parallel to the two short outer box plates 3, wherein the cross section of each short inner partition plate 4 is of an inverted boss shape, and distances between the two short inner partition plates 4 and the two short outer box plates 3 are equal. According to the dedicated mold, the bosses of the short inner partition plates 4 and the short outer box plates 3 protrude by the length of a half mortar joint, the bosses of the long outer box plates 5 protrude by the length of a mortar joint, and the protruding height of each tongue-shaped boss 7 is equal to the depth of a vertical dovetail groove 9 in an XPS thermal insulation board 8 which is inserted in a mold box through the bottom of the mold box.

Description

technical field [0001] The utility model relates to a new-type production tool for building materials, in particular to a special mold for producing one-time molding, decorative, heat-preserving and externally pasted blocks for producing masonry walls. Background technique [0002] In order to save energy and achieve sustainable development, the Chinese government forcibly raised the building energy-saving standard to 65%. At present, the main way of building energy saving is: "polystyrene board thin plaster external wall external insulation system". Due to the great difference in climate between the north and the south, the problems exposed are mainly manifested in: external wall cracking, external insulation layer falling off, and insulation layer durability Poor performance, insulation materials cannot last the same life as the building, and fires occurred during the construction process (such as the 11.15 catastrophic fire in Shanghai). In order to solve the problem of ...

AI Technical Summary

Problems solved by technology

There are two major technical defects in the block product produced by "vertical forming method": 1) considerable cracks are produced at the dovetail groove 9, which affects the connection strength between the concrete base 11 and the XPS polystyrene insulation board 8, and will bring damage to the building 2) The "vertical forming method" cannot produce decorative and thermal insulation blocks with decorative surface layer 12 at one time. The exterior block with decorative surface layer 12 is formed, and the difficulty of production is reduced, which solves the problem of cracks in the connection between the concrete base layer 11 and the XPS polystyrene insulation board 8, and the yield rate is upgraded to 100%.
