  • Patent number: 5417018
    Abstract: An apparatus for constructing a building (K) is disclosed. The building (K) includes a framework constituted of permanent columns (10) and permanent beams (11). The apparatus (S) is provided with a temporary framework, (13) which is constructed and located above the building (K) under construction. Lifting mechanisms (14) for lifting the temporary framework (13) are provided at and supported by the permanent columns (10) of the building (K). Each of the lifting mechanisms (14) is able to lift the lifting mechanism (14) itself along the permanent column (10) of the building (K). A crane (12, 413, 511) is provided at the temporary framework (13) for hoisting and conveying structural elements (U) of the building (K), for example, the permanent columns (10) and beams (11). Alternatively, movable hoists (131, 607) are provided so as to transfer at least under the temporary framework (13).

  • Patent number: 5117594
    Abstract: In an openable roof apparatus for a space, a stationary support structure is arranged about the space. A movable roof structure is supported by the stationary support structure and is movable with respect thereto. The movable roof structure having a first movable roof section and a second swing roof section. The second swing roof section is movable angularly about the central axis of the space with respect to the first movable roof section and is capable of being overlapped therewith. A guide arrangement is arranged on the stationary support structure and extends perpendicularly to a central axis of the space. The first movable roof section and the second swing roof section, which are overlapped with each other, are movable along the guide arrangement toward and away from the space.

  • Patent number: 5063730
    Abstract: In an openable roof apparatus for a space, a first and a second movable roof structures have their respective both ends which are supported respectively by a pair of stationary support structures for movement therealong. A pair of guide arrangements are arranged respectively on the pair of stationary support structures. The first and second movable roof structures are movable toward and away from each other along the guide arrangements. The first movable roof structure includes a plurality of movavble roof units having their respective axes which extend perpendicularly to the guide arrangements. The first and second movable roof structures are movable between a closed position where the movable roof units of the first movable roof structure cooperate with the second movable roof structure to close the space, and an open position where the movable roof units of the first movable roof structure are moved away from the second movable roof structure to open the space.
