摘要： A support structure, such as a bridge support structure for long spans between supports, includes a beam-like girder formed of reinforced concrete or prestressed concrete connected to and supported on the upper ends of support piers so that the girder is bending resistant. A strut framework extends between the girder and the support pier and includes a reinforced concrete compression strut extending diagonally upwardly from the lower end of the support pier to the girder at a position spaced outwardly from the support pier whereby the dead load of the compression strut is supported by tie rods extending from the compression strut upwardly to the girder or the pier. The compression strut forms one side of a triangle with the other sides formed by the girder and the support with the tie rods located within the triangle.

摘要： A controlled-discharge door assembly for particulate material or liquids includes a door member with a curved surface engaged by a large diameter roller mounted to a pivotable lever. The roller diameter is large in comparison to the length of the lever arm and provides variable torque multiplication as the roller moves along the curved surface of the door so that greater force is applied against the door when it is nearly closed. Resilient seals are provided around the door opening, the seal compressed by the discharge doors during closing to prevent leakage. The lever is moved over-center to hold the door in a locked position.

摘要： A prefabricated three-dimensional truss structure for a bridge, or the like, the truss formed from bars arranged to define triangular or rectangular patterns. The bars are formed from prestressed, high-strength concrete that are connected at their ends with assembly blocks that are prestressed, the prestress being preferably provided by the cables that prestress the bars, and which terminate at the blocks. A plurality of such unit trusses can be assembled to provide a truss structure for a bridge span, and the trusses can assume a wide variety of configurations.

摘要： A bridge structure particularly adapted for construction in skewed orientation with respect to a lower, overpassed roadway comprises a bridge portion, end abutments, and an intermediate support column. The bridge portion is constructed by supporting a plurality of precast concrete open-topped box-beams and precast L-shaped parapet-sidewalk members on temporary falsework at the bridge site. Upstanding from the precast box beams are wooden flanges which are trimmed in place to provide temporary supports of desired heights for precast slabs forming a bed for the upper roadway. The variable-height supports are used to form a crown in the roadbed, or to form an inclined roadbed which may be part of a banked curve. The precast box-beams are joined together by formed-in-place concrete diaphragms which are poured simultaneously with a concrete roadbed, whereby a monolithic squared off bridge portion is formed. An intermediate support column engages one of the diaphragms, thereby eliminating an exposed transverse support beam. The bridge portion is post tensioned by means of longitudinal and transverse post tensioned tendons. The squared-off bridge portion extends between two abutments, and any skew angle between the upper and lower roadways is accommodated in the abutments by a diagonal rake or relief ''''chamfer'''' of the abutment corner closest to the roadway. The far side of the squared off end of the bridge portion engages the top of the unraked portion of the abutment wall at an expansion joint, and is supported thereon; the remainder of the end of the squared off bridge portion being supported in cantilever manner, projecting beyond the diagonally raked corner of the abutment. The diagonally raked portion of the base wall of the abutment is substantially parallel to the lower roadway, thereby providing adequate horizontal clearance therefrom. The top of the abutment provides the approach roadway for the bridge. The top of the abutment is supported on and integral with the base walls of the abutment, with a portion cantilevered outward beyond the raked portion of the base wall to meet the squared off bridge portion.
