Non-penetrating bridge-cut-off metal skinned sandwich panel system

Abstract

The invention relates to a non-penetrating bridge-cut-off metal skinned sandwich panel system. The system is characterized in that an inserting opening seam allowance cavity sectional material is fixedly connected to the upper top surface of a heat insulation core material, and an inserting opening female opening cavity sectional material is fixedly connected to the lower top surface of the heat insulation core material; the rear side face of the heat insulation core material is wrapped by a sandwich panel inner panel, and the front side face of the heat insulation core material is wrapped bya sandwich panel outer panel; one end of a F-shaped fastening fastener is inserted into a cavity of the inserting opening female opening cavity sectional material, and the other end of the F-shaped fastening fastener is fixedly connected with a mounting fixing surface. The system has the beneficial effects that a thermal bridge caused by the fact that a screw penetrates through the panel is avoided, the thermal insulation effect of a system fastening part is guaranteed, the integrity of a thermal insulation layer covering surface is kept, the thermal insulation effect of a system connecting part is guaranteed, and the inner panel, the outer panel, the sectional material, the end cover and the side sealing edge form a complete sealing structure for wrapping a thermal insulation core material; the core material is not exposed, the end part of the cavity sectional material is sealed, and no thermal bridge exists on the whole.

Description

technical field [0001] The invention relates to the technical field of building metal surface enclosure systems, in particular to a non-penetrating broken bridge metal surface sandwich panel system. Background technique [0002] During the installation process of the composite veneer on site, the insulation material at the purlin part is deformed by the extrusion of the plate and the purlin, and the thinned insulation material becomes the weak point of the insulation layer, resulting in a thermal bridge effect, which affects the insulation effect of the entire system . [0003] Conventional external wall insulation metal plate products are usually installed on the keel or wall by means of screws penetrating the plate. The insulation layer is destroyed by the fastening screws. The screws serve as heat channels connecting indoor and outdoor, resulting in heat transfer along the screws.

Problems solved by technology

[0002] During the installation process of the composite veneer on site, the insulation material at the purlin part is deformed by the extrusion of the plate and the purlin, and the thinned insulation material becomes the weak point of the insulation layer, resulting in a thermal bridge effect, which affects the insulation effect of the entire system

[0003] Conventional external wall insulation metal plate products are usually installed on the keel or wall by means of screws penetrating the plate. The insulation layer is destroyed by the fastening screws. The screws serve as heat channels connecting indoor and outdoor, resulting in heat transfer along the screws. Loss, a thermal bridge effect occurs, which affects the insulation effect of the entire system

[0004] Due to the thermal expansion and contraction of metal materials, the screws and the metal material panel produce an interaction force, and the thermal expansion of the panel surface causes the surface to be uneven, and the screw rod and the metal material panel are repeatedly squeezed and deformed, which may easily cause the expansion of the nail hole and cause water leakage. Even the screws are sheared and damaged by the metal material panel, resulting in potential safety hazards
