Abstract: A barbed light weight concrete fastener and plate comprises a fastener with a head and two bendable legs. Each leg has a barb and a bump protruding therefrom. The fastener is pushed through a base ply and into a roof deck of cementitious material. The legs diverge to capture a concrete wedge between them. The barbs dig into the concrete wedge to increase resistance to a pullout force. The bumps create pressure points with the cementitious material that further resist pullout. A plate may be interposed between the fastener and the base ply. The plate has a number of openings therethrough of relatively large area. The openings are filled with plugs of asphalt that adhere to the base ply. Pulling of the base ply is resisted by the plate acting against the shear areas between the asphalt plugs and the base ply.

Abstract: An elongate hollow rock bolt, bolt installations, and process of effecting the same, wherein the bolt is slightly over-size relative to the transverse cross-section of the mine roff hole or aperture in which the bolt is to be installed. The bolt has a radial, transverse polygonal cross-section formed by contiguous deflectable resilient sides provided with outwardly directed fins, the latter being tapered. When the bolt is impact-forced into a mine roof aperture, the fins are forced inwardly, deflecting the bolt sides which, owing to their resiliency, maintain the fins and the aperture wall areas contacting the same under compression, thus increasing the holding effect upon the bolt. The latter may be grouted in, and also may have a pre-installed bearing plate provided with an aperture and slide-slots accommodating the fins.

Abstract: An elongate hollow rock structure and installation wherein the elongated shank of the bolt is hollow and has a series of outwardly bowed side or side portions that are capable of resilient deflection. Fin means are provided in sides or side portion, with the overall span of the fin means being greater than the bolt hole into which the bolt is to be impacted. The pin means are tapered so as to provide for ease of insertion of the bolt. Impaction of the bolt into a mine roof hole provides for a compression loading of the fins of the bolt shank such that these engage the aperture wall in a forced-compression state. Corrosion factors are limited to fin edge contact with the aperture wall of the bolt hole. Resilient sides' deformation at the core of the bolt shank is relied upon to compression load the fins for frictional contact with the aperture wall into which the bolt is implaced.
