External thermal insulation cement decorative panel with vertical joints as rigid sealing joints

Abstract

The invention relates to an external thermal insulation cement decoration panel provided with a covered channel type rigid sealing joint serving as a vertical joint and an assembling method thereof. The external thermal insulation cement decoration panel is characterized in that the cement decoration panel is internally provided with a metal or non-metal net; a three-dimensional decorative pattern is preformed on the outer side face of the cement decoration panel; the upper end face of the cement decoration panel is provided with a full-length convex key and metal hanging parts spaced by a certain distance, and the lower end face of the cement decoration panel is provided with a groove; the inner sides of the two side end faces are sunken inwards to form an exterior-high and interior-low step shape; and perforated metal plate strips are embedded in the sunken faces. During construction and assembly of the cement decoration panel, a sunk key type joint serves as a horizontal joint, and the covered channel type rigid sealing joint serves as the vertical joint. The gap of the joint is small, the decorative pattern at the joint can be successive so that a big integral three-dimensional pattern can be presented. The sunk key type horizontal joint has good permeability, and the covered channel type rigid sealing joint has good anti-cracking and anti-leakage performance.

Description

technical field [0001] The invention belongs to an exterior thermal insulation cement decorative panel of an exterior wall whose vertical seam is a dark groove type rigid sealing seam. 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 ...
