Abstract: Bridge construction method for a bridge formed by a series of beams placed between slabs, supported by angular profiles affixed to the beams. The method includes the steps of: fixing clips to edges of the upper surface of the beams, placing the beams on their supports, calculating the correct position of the angular profiles according to the shape or position of the beams; joining fasteners on the angular profiles, at an individual height determined according to the calculated positions; affixing the fasteners to the clips, so the angular profiles hang at the edges of the beams placing the slab on the angular profiles and casting concrete on the structure. The slabs are supported by angular profiles joined to the upper surface of the beams through a series of threaded protrusion carrying clips in said upper surface. Fasteners are joined to the clips and affixed to the angular profiles.

Abstract: A new method of sealing the seam between two adjacent sections of asphalt pavement deploys an adhesive elastomeric gasket which completely envelopes the vertical faces of the adjacent lanes on three sides—i.e., above, below and along each face. Since the gasket extends partly underneath each section of paving, it is laid down before each lane is paved, thereby taking advantage of the heat of the fresh asphalt to effectively and rapidly cure the adhesive component of the gasket to insure a strong bond on both sides of the seam.

Abstract: The surgical reamer has a hollow dome with apertures spaced apart arranged in arcs extending from an apex of the dome to the base portion of the dome, and removable teeth positioned in the apertures. Each cutting tooth has a flange that is aligned flush with the external surface of the dome, and a raised cutting edge extending above the flange and the external surface of the dome, and an interior passageway communicating between the outside and inside of the dome. In one embodiment, a base plate is removably secured on the base portion of the dome to provide closure of the central cavity of the dome.

Abstract: The surgical reamer (20) has a hollow dome (24) with apertures (26) spaced apart arranged in arcs (28) extending from an apex (30) of the dome to the base portion (32) of the dome, and removable teeth (22) positioned in the apertures. Each cutting tooth (22) has a flange (52) that is aligned flush with the external surface of the dome (24), and a raised cutting edge (50) extending above the flange and the external surface (36) of the dome, and an interior passageway (39) communicating between the outside and inside of the dome. In one embodiment, a base plate (56) is removably secured on the base portion (32) of the dome (24) to provide closure of the central cavity (34) of the dome.

Abstract: A light-weight, corrosion-resistant, readily installed bridge deck is formed of modular deck panels spliced to each other on site. Each of the deck panels is shop-fabricated by longitudinally welding flanges of adjacently placed multi-void extruded aluminum alloy structural elements. Transfer splices of longitudinally adjacent elongate elements are made by providing shear elements connecting individual elongate structural elements of each deck panel end-to-end prior to longitudinal welding of adjacent elongate elements, with the end joints between the elongate elements being arrayed in a staggered manner. A safety rail system is mounted to run alongside and above outer edges of the finished bridge deck mounted to a system of support girders.

Abstract: A safety net assembly and system is provided which includes at least two rods having attaching brackets at their ends. The brackets may be engaged over ledges in a frame that defines an opening over a subterranean work place. A net or webbing is slideably engaged on the rods, so that it may be opened for access and spread to cover the opening, to prevent a person from falling through the opening when the assembly or system is in place. Where there are insets in the ledges, the assembly or system may be left in place without interfering with the placement of a normal cover for the opening.

Abstract: Expansion joint cover assemblies are disclosed which are structured and dimensioned for use in covering expansion joints or spaces between adjacent structural sections of a building such as spaced floors or floor and wall sections. The assemblies include base members adapted to be positioned and secured to the adjacent structural sections and a leaf spring cover member fixedly interconnected to one of the base members at one end and bridging the expansion joint or space between the structural sections in a cantilever manner such that the cover member lies in a plane essentially flush with the floor section or sections and is structured and dimensioned to be slidably interconnected with the other base member to provide a secure, functionally effective and aesthetically pleasing assembly for accommodating translational relative movement of the structural sections.

Abstract: An expansion joint for buried inner placement over an expansion seam under a bridge roadway includes padding sheets fixed to the bridge deck on either side of the expansion seam in the deck. Padding slats are fixed to the bridge deck outboard of the padding sheets. A steel plate is superimposed above the padding sheets and padding slats and is provided on its underside with sliding pads and padding slats corresponding to the padding sheets and padding slats on the bridge deck. Rivets are anchored in the deck and accommodated in expansion slots in the sliding pads and steel plate. The rivets and slots are covered by guard covers. The joint is intended to be paved over.

Abstract: A system for attaching a bridge deck panel to a bridge structure which allows the panel to expand in lengthwise and sidewise directions independent of a bridge deck support structure. Brackets attached to members of a bridge deck support structure have undercuts on opposing ends which accommodate flanges on the bridge deck panel. Portions of the bracket overlying the undercut and flange prevent the deck panel from being separated from the deck support structure, but do not prevent the deck panel from lengthwise movement independent of the bridge structure due to temperature changes. To enable the panel to move in a sidewise direction, a space is provided between the outermost edge of the deck panel flange and the length of the undercut.

Abstract: The present invention provides a bridging system which serves to bridge expansion gaps, used in the roadbeds of major structures such as bridges or viaducts. The supporting portion of the system comprises bearers, the upper sides of which are level with the surface of the roadway. The bearers rest on crosspieces that are supported in such a manner as to be able to move, within recesses below the roadway. The secondary gaps between the bearers are sealed by means of elastic rubber strips. In order that any contraction or expansion of the structure is distributed evenly across the secondary gaps, the crosspieces are controlled by means of connecting rods. The ends of these connecting rods are articulated onto opposing edges of the gap. In contrast to conventional systems of this kind in which connecting rods are disposed beneath the crosspieces, in the present system, connecting rods pass through the crosspieces.
