Portal apparatus (40) is provided for interconnection between adjacent first and second structures (32, 34) in order to maintain operative communication between the structures (32, 34) under seismic conditions. The apparatus (40) includes a portal assembly (36) together with coupling assemblies (38, 40) permitting translation and rotational movement of the portal assembly (36) about three orthogonal axes (X, Y and Z) in space. The first coupling assembly (38) serves to secure assembly (36) to structure (32) and permits rotation about and translation along the X axis, as well as rotation about the Y and Z axes. The second coupling assembly (40) slidably connects the remote end of assembly (36) to structure (34) and accommodates Y and Z axes translation.

Seismic portal

A support for connecting a facade to at least one and preferably two buildings permits limited movement of the facade during seismic disturbances. The support includes a coupler presenting a projecting member and a mount presenting a receiver complementally configured with the projecting member. In one application, the projecting member and receiver define a track for permitting relative translational movement therealong, while in another application the projecting member and receiver define a hinge which may permit both limited pivotal movement and limited translational movement between the projecting member and the receiver. A plurality of tracks oriented in parallel or in perpendicular orientations may be employed to permit movement along different axes, and in particularly preferred embodiments wherein the facade spans the gap between two adjacent buildings, the support permits limited movement of the facade relative to the buildings along three orthogonal axes of translational movement and limited pivoting about three orthogonal axes.

The present invention consists of a metal trench grating and the method of manufacture by which it is constructed. The trench grating consists of plural cross bars having equi-spaced slots and a plurality of elongated rails inserted within the respective cross bar slots, and wherein a single weldment across the bottom of each cross bar provides complete fastening of the assembled trench guard. The method of manufacture stresses simplicity and quick assembly as the plural longitudinal rails are inserted in the plural-slotted cross bars and supported for final welding across the bottom central slot of each cross bar to produce the final form trench grating.

Trench grating and method of manufacture

Apparatus for concealment and abridgement of relatively larger expansion joint voids between structures exhibiting orthogonal relative movement. The assembly consists of base plate and slide structure secured in orthogonal disposition on opposite sides of an expansion void, with angular matching cover plate structure supported on said base plate and slide structure.
