  • Patent number: 8875469
    Abstract: A sleeve for protecting from deterioration and anchoring an embedded end of a post in the ground. The sleeve, molded from unperforated, resilient material, conforms to the exterior post dimensions and extends for at least the desired embedment distance. One or more inwardly projecting notches are cut into the post. The sleeve includes one or more reversible snap domes molded into the sleeve at locations coinciding with the post notches. The snap domes flex to an outwardly concave position as the post is being inserted into the sleeve and then snap to an inwardly concave position once the post is fully installed and the snap domes align with the notches. The inward concavity of the snap domes extends into and engages the post notches to prevent the sleeve from being removed from the post. When embedded into the ground, backfill material prevents the snap dome from being deflected into the outward concavity position, thus anchoring both post and sleeve in the ground.

  • Patent number: 8635833
    Abstract: An earth retention system constructed with a top-down process that can be used for permanent below-grade structures, similar to a “soldier beam and lagging wall,” consists of vertical soldier piles, drainage and waterproofing, and a finished, reinforced concrete facing. The concrete facing is placed pneumatically (i.e., using so-called shotcrete). The system is well-suited to constructing below-grade portions of buildings where excavation lay back is not practical or cost effective and can incorporate permanent lateral support from tieback anchors. The below-grade structure is constructed by excavating down part way, constructing a waterproof “lift” portion of the ultimate structure, excavating down another part way, constructing another waterproof lift portion in a manner to be tied in with the lift portion immediately above, and repeating these steps until the below-grade structure is constructed to the desired depth.

  • Patent number: 8637767
    Abstract: A first device useful as a support base for utility poles, which integrates an anti-theft security system directed to prevent theft of power supply wires used in underground power distribution systems. The security system includes a dual internal conduit system for housing the wires and at least two head bolts inserted in an individual lateral straight conduit. Similarly, a second device includes a mold having an inverted T-shaped housing for the wires and a head bolt inside the upright conduit section of said inverted T-shaped housing. In both devices, the wires are moved in an angled position and secured by tightening the corresponding bolt.

  • Patent number: 8615964
    Abstract: An improved mounting structure for the posts of hand rail systems including a mounting arm member positioned within a sleeve monolithically formed within the inner chamber of the post. The sleeve includes a slit that allows for the outflow of water, thereby limiting corrosion and degrading of the post and mounting structure. A series of nubbed projections create grooves within the surface of the sleeve, to secure the mounting arm into the sleeve in a strong manner. A secure fit limits the amount of liquid trapped within the sleeve reducing corrosion. The mounting arm has smaller dimensions, reducing the chances that the arm comes into contact with support rods embedded within the concrete during installation. By avoiding contact with the support rods, concrete spalling is dramatically reduced, adding to the lifetime of the rail system.

  • Patent number: 8613178
    Abstract: An anchoring element that provides anchorage in an object, and is compressible in the direction of a compression axis under local enlargement of a distance between a peripheral anchoring element surface and the compression axis. The anchoring element has a coupling-in face which serves for coupling the mechanical vibrations into the anchoring element, which coupling-in face is not parallel to the compression axis. The anchoring element further includes a thermoplastic material which in areas of the peripheral surface enlargement forms at least a part of the surface of the anchoring element.

  • Patent number: 8607524
    Abstract: An anchoring device including an anchoring element suitable for being anchored an object of construction material with the aid of mechanical vibrations. The anchoring element includes a thermoplastic material and a tool. The thermoplastic material forms at least a part of a radially outer surface of the anchoring element, and the tool has a proximal portion and a broadening portion distally of the proximal portion. The broadening portion has an outer second cross-section, the second cross section being larger than the first cross section but being adapted to the first cross section so that the tool can be moved with respect to the anchoring element while the broadening portion is in the axially-extending opening and locally expands the anchoring element while thermoplastic material of the anchoring element that surrounds the broadening portion is in a solid state.

  • Patent number: 8567743
    Abstract: A system for attaching a columnar building member to a structural support member, uses one or more connecting brackets comprising a flat base plate having an inner perimeter and an outer perimeter, with a plurality of apertures disposed along the base plate. A socket extends from the inner perimeter of the base plate, with the perimeter of the socket conforming to the inner perimeter of the base plate, and with a plurality of apertures disposed along the socket. The columnar building member is attached to the connecting bracket via a plurality of fastening means through the apertures disposed along the socket. The columnar building member and connecting bracket are attached to the structural support member(s) via a plurality of fastening means through the apertures disposed along the base plate.

  • Publication number: 20130255169
    Abstract: A post-tensioned concrete cap foundation has helical anchors with pipes having several helical discs welded around the pipe perimeter to spin drill deep into subsurface soils or other soft materials with holes in the pipe for high pressure-grouting in place. The helical anchor pipes are coupled to a tensioning element for pulling and post-tensioning the helical anchor. The helical anchors are tension anchors which can be converted to compression anchors. The helical anchors in tension serve to pull the foundation cap down to compress the underlying soil while the compression anchors limit the maximum settlement of the concrete foundation cap. The foundation also includes perimeter-forming and interior corrugated metal pipes with upper and lower sleeved horizontally extending radial bolts that are secured to the pipes and post-tensioned to provide lateral foundation compression.
