A construction apparatus comprising a framework (3) installed above a completed structure of a building (10) so as to form a working space for construction work including installing permanent columns (6) over the completed structure, guide posts detachably held on the completed structure, elevating and locking mechanisms provided on the framework for elevating the framework to form the working space and for locking the framework to the guide posts, and construction means mounted on the framework and capable of carrying out the construction work in the working space. The framework (3) is provided with a cover (16) for covering the working space. A construction method of constructing a multistory building in ascending order of stories, comprising steps of elevating a framework (3) placed on a completed structure of the building to form a working space over the completed structure, locking the framework at an elevated position to the completed structure, sequentially installing permanent columns (6) in the working space, installing beams (7) between the fixed permanent columns (6), executing construction work in a structure formed of the permanent columns (6) and the beams (7), and disengaging the framework (3) from the completed structure. The construction apparatus and the construction method can be fabricated at a reduced cost and, in constructing multistory buildings, and the construction apparatus saves labor and enables the uninterrupted execution of construction work regardless of weather conditions. The construction apparatus is sufficiently resistant to earthquakes. |
