External thermal insulation cement decoration panels forming concealed groove type flexible sealing seams serving as vertical seams

Abstract

The invention discloses exterior wall external thermal insulation cement decoration panels forming concealed groove type flexible sealing seams serving as vertical seams. Each decoration panel is characterized in that the decoration panel is internally provided with a metal or nonmetal net; three-dimensional decorative patterns are prefabricated on the outer side surface of the decoration panel; a full-length bulged key is arranged on the upper end surface of the decoration panel; metal hangers are arranged on the upper end surface of the decoration panel at a certain interval; the lower end surface and the end surfaces on the two sides of the decoration panel are respectively provided with a groove. When the cement decoration panels are assembled, horizontal seams are sunk-key type seams, and the vertical seams are concealed groove type flexible sealing seams in which sealant is poured and leakage-proof insertion boards are inserted. According to the invention, the jointing seams are quite narrow, so that the decorative patterns can be continuous in the jointing seams, and a whole large picture with three-dimensional patterns can be presented. The sealant in the concealed groove type sealing seams is not irradiated by solar ultraviolet rays, so that the service lifetime of the sealant can be greatly prolonged. The sunk-key type horizontal seams are high in ventilation performance.

Description

technical field [0001] The invention belongs to an exterior thermal insulation cement decorative panel with dark groove type flexible sealing seams for vertical seams. Background technique [0002] The application number is 201410623760.8, and the patent application document titled "Molding Method of Cement Decorative Board with Pre-embedded Pendant and Reserved Steel Wire Mesh Lap Joint" describes the cement decorative board. Rigid joints of seams, such joints are usually about 2cm wide, the decorative patterns at the joints cannot be continuous, and a large overall three-dimensional pattern cannot be assembled, the artistic expression of the finish is greatly limited, and a mortar pointing is required during construction and assembly process, increase construction labor costs and extend the construction period. Contents of the invention [0003] The purpose of the present invention is to change the seam method, the horizontal seam adopts the hidden key type seam, and th...
