[0002] Metal-faced rigid polyurethane sandwich panels refer to panels with upper and lower layers of metal sheets and a core of rigid polyurethane. They are divided into: galvanized steel sandwich panels, hot-dip galvanized color steel sandwich panels, electro-galvanized color steel sandwich panels, aluminum-zinc color steel sandwich panels, etc. according to the surface material; and divided into: metal foam plastic sandwich panels, metal inorganic fiber sandwich panels according to the core material.

[0003] Metal-faced rigid polyurethane sandwich panels are usually used for roof panels, wall panels, partition panels, ceiling panels, etc. At this time, the metal-faced rigid polyurethane sandwich panels need to be fixed and connected in pairs. However, the current metal-faced rigid polyurethane sandwich panels are usually bonded with glue, etc., which has weak adhesion. As the fixation weakens over time, it leads to loosening. In addition, this method is inefficient, which increases the manpower and material resources for the installation of metal-faced rigid polyurethane sandwich panels. Utility Model Content
