The invention discloses a building
curtain wall connecting piece, and relates to the technical field of building curtain walls, the building
curtain wall connecting piece comprises a
keel frame, a plurality of panels are movably connected to the outer side of the
keel frame, a reinforcing plate is movably connected to the outer side of the
keel frame, a plurality of buckle connecting assemblies are jointly arranged between the keel frame and the panels, and through the buckle connecting assemblies, the reinforcing plate is movably connected to the outer side of the keel frame. During maintenance, the second
insertion block is rotated by 90 degrees, the first
helical rack is separated from the second
helical rack, fixation can be easily released, the first
helical rack and the second helical rack are in
close contact under the action of the first spring, and the installation process is simple and efficient. The damaged panel can be conveniently and accurately positioned, disassembled and replaced, the maintenance difficulty and cost are effectively reduced, and the convenience and economical efficiency of
curtain wall installation and maintenance are improved.
