Shaft Reinforcement Adjacent Earth's Surface Patents (Class 52/170)
  • Patent number: 10655356
    Abstract: A pole reinforcement system and method for improving the stability of a pole with both an above-grade and below-grade installation. The pole reinforcement system generally includes a sleeve assembly which is secured around a pole via one or more retainers which may comprise brackets, securing bands, or other structures. One or more insertion attachments are utilized so that the sleeve assembly may be secured to the pole at a position below-grade. The sleeve assembly may comprise one or more sleeves which are secured around the pole. By utilizing the present invention to reinforce the pole both above- and below-grade, the stability of the pole may be greatly improved over prior reinforcement methods.

  • Patent number: 10472792
    Abstract: The present disclosure is directed to a tower assembly for a wind turbine having a tower flange that can accommodate foundations and/or nacelles of varying sizes. The tower assembly includes one or more tower sections having an integral tower flange that can be secured to a foundation, atop the tower section(s), and/or at a mid-height tower location. Further, the tower flange includes a substantially cylindrical wall defining an outer diameter and an inner diameter separated by an increased radial thickness. Thus, a radial offset is defined between the outer diameter of the tower flange and the corresponding tower component, i.e. the foundation, another tower section, or a yaw bearing. Accordingly, the larger radial thickness of the tower flange allows the flange to accommodate foundations or turbines of varying sizes with one common tower.

  • Patent number: 7874111
    Abstract: A floor system for use in a conservatory or other annexes includes a panelled floor and a frame construction. The frame construction at least partly surrounds the panelled floor. The floor system is anchored in the ground by at least one ground anchor. The use of ground anchors makes a prior excavation substantially completely unnecessary. The floor system is a dry construction system, in which no construction material containing water are used during construction of the floor system.

  • Patent number: 7827748
    Abstract: A tower foundation (10) comprises a base slab (11), a plurality of pillar slabs (12), and a crown stab (13). The base slab (11), pillar slabs (12) and crown slab (13) are all retained in position by six steel guide rods (18) that extend upwardly from the base slab (11). The six guide rods (18) have externally threaded ends configured to receive internally threaded mounting bolts (20). The guide rods are arranged in a generally triangular pattern. The pillar slabs are rectangular with their sides being undercut or sloping outwardly from the bottom surface to the top surface, i.e., the sidewalls diverge outwardly as they extend upwardly. The outwardly sloping sidewalls aid in preventing the foundation from tilting over time.

  • Patent number: 7823348
    Abstract: A system and method which positions and orients a wall post or column during positioning and supports the post after it has been positioned. The system embodying the principles of the present invention is set and contacts surfaces of the post. The system includes two monolithic one-piece anchor blocks located on a level surface to have top faces thereof located co-level with each other and tie and cross rods each of which has a surface that is vertically oriented when in use and which abuttingly engages a corresponding surface of the post when in use. At least one tie rod is connected to the anchor block top faces and the cross rod is attached to the tie rod. The tie rod is located at a desired position relative to a reference plane and the cross rod is located at a desired location relative to a reference location. The post is located between the two anchor blocks and in abutting contact with the vertically oriented surfaces of the rods.

  • Patent number: 7815157
    Abstract: A method for reinstating a pole standing in ground comprising, abutting an inner surface of a sleeve against an outer surface of the pole so as to have a lower portion of the sleeve penetrating the ground and an upper portion of the sleeve projecting above the ground, and sliding a secondary member against an outer surface of the sleeve so that the secondary member locates against the sleeve and projects above the ground and into the ground, wherein the construction is such that the sleeve and secondary member located against the sleeve jointly form a bridging beam incorporating a box section reinforcement of the bridging beam. The formation of this box section substantially improves the strength of the bridging beam above what would be expected from the strength of the individual components.

  • Patent number: 7735268
    Abstract: An apparatus for bracing a masonry wall that is bowing or has begun to buckle as a result of hydrostatic pressure and/or other forces as may occur with the foundation or basement wall of a building. The wall restraint system includes a vertically disposed beam, which is positioned against a vertical concrete masonry wall and secured in place by a bottom bracket and a top bracket. The beam reinforces the wall and prevents further bowing, buckling, or potentially collapsing of the wall. One end of the beam is secured to the floor by a bottom bracket. The bottom bracket preferably receives the lower end of the beam. The upper end of the beam is secured against the basement wall by a top bracket or offset connector, which in turn is secured to one of the overhead floor joists. The beam may be offset to avoid piping or the like.
