Hook connector with plastic fire relief
ActiveUS20060260244A1Cross beams from sagging or droopingPrevent pullbackCeilingsWallsNormal caseAbutment
A connector for a cross beam that hooks into a slot in a main beam in the grid of a suspended ceiling. The connector has a plastic encasement that forms abutments about a metallic core. The abutments position the connector within the slot, and prevent further entry of the connector into the slot, under normal conditions. The plastic abutments melt away during a fire, so that the beam can expand longitudinally to relieve stresses in the beam, without the beam buckling. Ridges on the bottom of the metallic core prevent pullback of the connector from the slot, during a fire, to prevent the ceiling from sagging or drooping.

According to the device for the stamping die, the height of the electric driving module can be adjusted according to the frequency of stamping a material strap of the stamping die, and the effective stirring distance of a swing plate to the material strap through a telescopic rod, a semicircular block and an arc-shaped friction pad under different stamping frequencies is ensured; and further, the fact that the stamping frequency is consistent with the stirring frequency of the arc-shaped friction pad to the material strap is ensured. A limiting block matched with the material strap prevents the material strap from being pulled back under external force, and theeffectiveness of stirring the material strap forward of the swing plate through the telescopic rod, the semicircular block and the arc-shaped friction pad is ensured.
