External thermal insulation cement decoration panels provided with concave edges and forming concealed groove type rigid sealing seams serving as vertical seams

Abstract

The invention discloses exterior wall external thermal insulation cement decoration panels provided with concave edges and forming concealed groove type rigid 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; the upper edge, the left edge and the right edge of the decoration panel are respectively provided with a concave edge having appropriate width and depth; 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; a groove is arranged in the lower end surface of the decoration panel; the inner sides of the end surfaces on the two sides of the decoration panel are recessed and form steps whose outer portions are higher than the inner portions; and punching metal strips are pre-embedded in the recessed surfaces. When the cement decoration panels are assembled, horizontal seams are sunk-key type seams; the vertical seams are concealed groove type rigid sealing seams; and horizontal and vertical dividing seams are formed by the concave edges. The sunk-key type seams are high in ventilation performance, and the concealed groove type rigid sealing seams are high in anti-cracking and anti-seeping performance. The diving seams formed by the concave edges have appropriate width and are straight in shape.

Description

technical field [0001] The invention belongs to an exterior thermal insulation cement decorative panel of an exterior wall provided with concave edges and vertical seams of hidden groove type rigid sealing 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 seams of seams, the grid seams formed by such seams appear to be too wide (more than 2cm) in appearance, not tall enough, and require a more labor-intensive mortar pointing process. Contents of the invention [0003] The object of the present invention is to narrow the width of the grid seam by setting concave edges and changing the seam method. , the appearance is tall and straight, and the mortar pointing process is eliminated. [0004] In order to achieve the above object, the present invention ...
