Installation and leveling method of external thermal insulation cement decorative panel with concave edge hidden key joint

Abstract

The invention relates to an external thermal insulation cement decoration panel provided with a concave edge and sunk key type joint and a mounting and leveling 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 edge of the cement decoration panel is provided with a concave edge with an appropriate width and depth; the upper end face of the cement decoration panel is provided with a full-length convex key and metal hanging parts at certain intervals; and the two side end faces of the cement decoration panel are planes or the outer edges of the cement decoration panel are provided with convex edges with an appropriate height, and perforated metal plate strips are embedded in the two side end faces or the outer edges of the cement decoration panel. During construction and assembly of the cement decoration panel, horizontal joints serve as sunk key type joints, the concave edges form horizontal grid division joints, vertical joints serve as perforated metal plate strip coped joints, special mortar is embedded in the joints compactly in a filling mode, and vertical grid division joints with the same depth as the horizontal grid division joints are formed. The perforated metal plate strips are good in flatness, accurate in shape and size and capable of well meeting the requirements of the production process of the cement decoration panel. The perforated metal plate strip coped joints have good tensile strength and can effectively protect the mortar joints against cracking and leakage.

Description

technical field [0001] The invention belongs to a method for installing, anchoring and leveling the base wall surface of an external thermal insulation cement decorative panel provided with recessed side hidden key joints. Background technique [0002] In the patent application document with the application number 201410624106.9 and titled "Method for Forming Cement Decorative Panel Using Laminated Mold Box and Steel Wire Mesh Separation and Laying", a scheme of cement decorative panel with steel mesh on four sides is disclosed. During the implementation, many problems were found, such as the flatness of the steel mesh cannot meet the requirements of the production molding process, it is difficult to accurately pre-embed the steel mesh in the mold, the four sides of the mold are not tightly sealed, resulting in burrs, and mortar filling and pointing during construction and assembly The workload is large, etc. If these problems are not solved, it will be difficult to realize...

Problems solved by technology

[0002] In the patent application document with the application number 201410624106.9 and titled "Method for Forming Cement Decorative Panel Using Laminated Mold Box and Steel Wire Mesh Separation and Laying", a scheme of cement decorative panel with steel mesh on four sides is disclosed. During the implementation, many problems were found, such as the flatness of the steel mesh cannot meet the requirements of the production molding process, it is difficult to accurately pre-embed the steel mesh in the mold, the four sides of the mold are not tightly sealed, resulting in burrs, and mortar filling and pointing during construction and assembly heavy workload

If these problems are not solved, it will be difficult to realize mechanized production, and the construction and assembly will be labor-intensive and time-consuming.
