Building construction method and lifting device

摘要

A lifting device for lifting an upper portion of a building which comprises a roof and a method of constructing a building using such a lifting device. The lifting device includes a base plate arranged to be mounted to an edge region of a support and a lifting platform attached to an actuator and capable of vertical movement by means of the actuator. The base plate has a first portion arranged to abut a substantially horizontal face of the support and a second portion arranged to abut a substantially vertical face of the support. The actuator is adjustably mounted to the base plate such that the position of the actuator is horizontally and/or vertically adjustable relative to the base plate to ensure a plumb lift.

1. A lifting device for lifting an upper portion of a building comprising a roof and an underside, the building further comprising a support having an edge region comprising a substantially horizontal upper face and a substantially vertical side face, the lifting device comprising:
a base plate configured to be mounted to the edge region of the support, the base plate having a generally Z-shaped cross-sectional configuration comprising an upper horizontal portion configured to abut the substantially horizontal upper face of the support, a vertical middle portion configured to abut the substantially vertical side face of the support, and a lower horizontal portion configured to support an actuator; a lifting platform configured to abut and lift the upper portion of the building such that a lower portion of the building may be constructed or inserted within a space between the support and the underside of the upper portion of the building; and an actuator movably coupled along a length of the actuator to the lifting platform and configured to vertically move the lifting platform, the actuator fixed to a vertically adjustable plate which is adjustably mounted to the lower horizontal portion of the base plate such that the actuator is configured to be adjusted vertically relative to the base plate to ensure a plumb lift, the actuator further configured to be adjusted horizontally relative to the base plate.
