Uni-directional and multi-directional mechanical structural bearing
A uni-directional and multi-directional mechanical bearing suitable for supporting structures such as bridges comprises a removable cassette comprising a sliding layer composed of a low friction material such as PTFE. The removable cassette allows for the replacement of the sliding layer without needing to remove or replace the entire bearing. The bearing can be part of a kit that includes a replacement cassette having a varying thickness that corresponds to the uneven wear on the sliding layer of the removable cassette and compensates for an eccentric pressure on the bearing when under load.
HOLD DOWN SYSTEM WITH DISTRIBUTED LOADING FOR BUILDING WALLS
A hold down system for a building wall comprises a first rigid member and a second rigid member, the second rigid member being vertically spaced apart from the first rigid member, the first rigid member is supported on a horizontal member of a stud wall, the first and second rigid members including first and second openings, respectively; a tie-rod with a lower end portion for being anchored to an anchorage, the tie-rod extending transversely through the first and second openings, the tie-rod dividing the first and second rigid members into a first lateral section on one side of the tie-rod and a second lateral section on a diametrically opposite side of the tie-rod; first support and second support disposed between the first and second rigid members, the first support being disposed in the first lateral section, the second support being disposed in the second lateral section, the tie-rod extending through the first and second rigid members outside of the first support or the second support; and a nut threaded to the tie-rod, the nut exerting pressure on the second rigid member to place the tie rod under tension loading, the tension loading is transferred by the second rigid member to the first and second supports to subject the first and second supports to compression loading, thereby causing the first rigid member to press on the horizontal member of the stud wall via the first and second lateral sections of the first rigid member, thus distributing the compression loading.

Systems and methods for installing and stabilizing a pier
A device for stabilizing a metal pier installed in the ground. The device includes a device to provide lateral support to the pier and a shaft configured so that a force imposed, parallel to an axis of the pier, on the device is not imposed on the pier. A method of stabilizing a pier installed in ground to support a structure. The method includes determining the location of an unstable soil zone of the ground and a stable soil zone of the ground. The method also includes placing a stabilizing plate in the unstable soil zone to provide lateral support to the pier. A device configured to lift a foundation slab above the ground. The device includes a lifting bolt and apparatus that restricts lateral deflection of the pier when a torque is applied to the lifting bolt to raise the slab. A method of stabilizing soil around a pier.
Wall lifting methods
Methods of lifting structures such as a wall of a building. A fluid that is under pressure is injected beneath the base of the wall. The pressure of the injected fluid acts against the base of the wall to lift the wall vertically. In some embodiments, a supplemental lifting force mechanism can be attached to the wall to apply a supplemental lifting force to the wall that acts together with the lifting force applied by the injected fluid. The supplemental lifting force lightens the wall, reducing the amount of lifting force required to be applied to the wall by the injected fluid.
METHOD FOR CORRECTING CONCRETE PLATE TILTING ON SUBSIDED GROUND
An object of the present invention is to provide a method for correcting the tilt of adjacent concrete slabs on subsided ground and connected at a joint part by tie bars or dowel bars caused by the subsidence of the joint part. The method of the present invention as a means for resolution comprises a step of pushing up a tilted concrete slab by: with respect to concrete slabs adjacent to each other across a subsided joint part, drilling an injection hole for injecting an expandable resin in one concrete slab at a point 10 to 200 cm away from the joint part and also in the other concrete slab at a point 10 to 200 cm away from the joint part, the point in the other concrete slab being on a line that is orthogonal to the joint part and has the point in the one concrete slab thereon; simultaneously starting an operation of intermittently injecting an expandable resin from both of the injection holes; and expanding the expandable resin below both of the concrete slabs.
