Technical Field

The invention relates to the technical field of building material assembly, in particular to a hanging system for a building heat-insulation decorative structure plate.

Background

In the building decoration industry, new processes and new materials are continuously emerging. The heat-insulating decorative board is economic, beautiful, colorful, energy-saving and environment-friendly, and is widely applied to decorative walls and cylindrical surfaces. In recent years, the use of stone construction techniques for interior wall surfaces or exterior wall surface decoration of buildings has been emerging in many cities. The construction process is mainly characterized in that a 'dry' part, an anchor bolt and a hanging fastener are fixedly arranged on a wall and a cylindrical surface.

At present, the plates are installed by adopting a method of mainly adhering and secondarily hanging. The existing hanging fastener has weak holding force, cannot be independently hung and is inconvenient to use; the air pressure performance is poor is prevented to the catching groove panel of installation, easily drops, takes place quality defects such as "flower face" easily, and the comparatively outstanding panel that easily drops also has the potential safety hazard. The intensive forbidden external thermal insulation anchor system value of the external wall in each province in half a year is profound in the industry. The national insulation society integrated board society recommends reading that insulation and decoration integrated board system safety is the life line of insulation and decoration integrated boards, and explains the severity of the problem.

To the above-mentioned problem, patent CN112796482A discloses panel forked tail hook formula pendant, and this pendant can firmly grasp panel like the hawk claw, and the wind pressure performance is strong, is difficult to drop, and factor of safety is high for the panel of installation. However, since the plate material is fitted into the dovetail hook hanger of the plate material only from the side surface, the plate material needs to be provided with a hook groove penetrating the side surface, which has a certain influence on the overall strength of the plate material.

The fundamental reason of the hanging safety of the integrated board is solved; the plate and the pendant should have a connection process of an integral structure, an occlusion function, a buckling function, a shockproof function and a flexible connection function, and the double expansion bolt is anchored with the wall body to form a structural process of three-level double protection independent of bonding. The plate should have independent mounting capacity, so that the vertical bearing capacity is reduced.
