The invention relates to a reinforcing mat (1) for reinforcing a top layer of a ground, which top layer consists of bitumen, asphalt or a hydrocarbon-containing material of like nature, in which the reinforcing mat (1) is a mat woven with longitudinal wires (2, 3) and provided with reinforcement elements (4) running in the transverse direction of the mat, in which the reinforcement elements (4) consist of helically twisted steel profiled wires of essentially rectangular cross section.

A structural reinforcement for a hollow section at least part of at least one of whose surfaces is the internal surface of an external panel comprising a rigid reinforcing member having a shape that substantially conforms to the cross section to be reinforced. An expandable adhesive material is provided over a portion of the surface of the rigid reinforcing member and the shape of the rigid reinforcing member and the amount and location of the expandable adhesive is such that upon foaming the fo...

A reinforcing net for use in a reinforcing layer is formed by spacing two parallel spreader yarns under tension and wrapping weft yarns around the two spreader yarns. The reinforcing net can either be affixed to an adhesive coated substrate or coated with adhesive at the intersections of the yarns to bond the net together. The net may be affixed to a plurality of substrates to form a laminate. The net, a ribbon of net with one substrate, and the laminate, may be used in making and reinforcing sp...

An apparatus and method for lifting a plurality of reinforcing bars (rebars) all at one time, and holding them in vertical position while they are connected one at a time to the upper ends of steel elements such as bolts or reinforcing bars protruding from concrete. The apparatus has an elongate lower element with a row of blind holes or recesses in its upper end to receive the lower ends of the bars. An elongate upper element has a row of through holes in registry with the blind holes. The two ...

A brick or masonry structure is drilled to receive an elongate reinforcing assembly comprising a core with one or more fabric sleeves over most of its length. The sleeves are injected with grout that seeps through the fabric to bond to the drilling wall. It may bond directly to the core or to a tube through which the core extends. The core is anchored to the structure at or near the mouth of the drilling while a tube farthest from the mouth may have a connection to the core that allows the core ...

Sulfur containing organosilicon compounds having the formula: in which Z is: ##STR1## where R.sub.1 is alkyl of 1 to 4 carbon atoms cyclohexyl or phenyl and R.sub.2 is alkoxy of 1 to 8 carbon atoms, cycloalkoxy of 5 to 8 carbon atoms or alkylmercapto of 1 to 8 carbon atoms, alk of a divalent aliphatic hydrocarbon or unsaturated aliphatic hydrocarbon or a cyclic hydrocarbon containing 1 to 18 carbon atoms and n is a whole number from 2 to 6 are used as reinforcing additives in rubber mixtures con...

A reinforcing rod includes a rectilinear and elongated shaft that has a centrally disposed longitudinal axis and includes a monolithically formed spine extending along an entire length of the shaft and parallel to the axis. The spine includes monolithically formed coextensive rings equidistantly spaced and juxtaposed along a length of the shaft. The spine bifurcates the rings. The rings form a generally spiral pattern about the shaft. The shaft is formed from steel. A mechanism is included for p...

A reinforcing structure designed for handling compression stress states when the structure is molded into a composite. The structure, specifically a wrapped cord with metallic filaments contained therein, is suitable for both compression and tension load forces. The reinforcing structure has a core comprising a plurality of essentially straight, nested filaments arranged in parallel, the filaments forming a line of contact with adjacent filaments that extends along the length of the filaments. W...

A reinforcing member such as a cable bolt is formed of a multiplicity of helically stranded wires wound around a straight core or king wire. At least the outer wires are formed with a plurality of spaced helical ribs extending along the entire length thereof.

With reference to FIG. 2, a preferred form of the invention comprises a reinforcing element for use in strengthening and stiffening wooden beams 6. The reinforcing element comprises a length of angles steel 1 attached to an offset nail plate 2. The angled steel 1 is laid against the wooden beam 6 and the nails 9 of the nail plate 2 are driven into the wooden beam 6. The reinforcing element may have a number of nail plates spaced along its length, or alternatively a single nail plate extending su...
