Technical Field

[0001] The utility model relates to the field of building construction, in particular to an automatic connector for hollow sandwich panels. Background Art

[0002] As a building's floors increase, its overall weight gradually increases, and most of the building's weight comes from the weight of the load-bearing walls. A hollow-web sandwich panel is a new type of spatial grid structure system. Its structural feature is that each rib of the densely ribbed well-shaped floor is hollowed out, but the reinforced concrete at the intersection is retained, dividing the original rib into upper and lower ribs, thus forming a hollow-web cross-beam. The "shear key" at the intersection, which has the mechanical properties of a "block unit," enables the upper and lower ribs of the hollow-web sandwich panel to work together. Automation connectors are commonly used in automated equipment and production lines to achieve fast and reliable connections between devices.

[0024] During the assembly of the U-shaped frame 21, the device can actively move the U-shaped frame 21 closer to the lower end of the lower rib 2. At this time, the inner walls of the U-shaped frame 21 come into contact with the end angles of the positioning wedge 314 in the process of contacting the side surfaces of the lower rib 2. At this time, as the U-shaped frame 21 gradually moves upward, it resists the positioning wedge 314 and slides inside the sliding groove 312, and compresses the air spring 313 during the movement. When the U-shaped frame 21 moves upward until the trapezoidal hole 315 coincides with the sliding groove 312, the positioning wedge 314 is reset by the air spring 313, so that the positioning wedge 314 passes through the trapezoidal hole 315, and the U-shaped frame 21 and the lower rib 2 are automatically and stably connected.
