Abstract

A construction apparatus comprising a framework installed above a completed structure of a building so as to form a working space for construction operations including installing permanent columns 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 equipment mounted on the framework and capable of carrying out the construction operations in the working space. The framework is provided with a cover for covering the working space. A construction method of constructing a multistory building in ascending order of stories comprises the steps of elevating a framework 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 in the working space, installing beams between the fixed permanent columns, executing construction operations in a structure formed of the permanent columns and the beams, and disengaging the framework from the completed structure. The construction apparatus can be fabricated and the construction method can be performed at a reduced cost and, in constructing multistory buildings, the construction apparatus saves labor and enables the uninterrupted execution of construction operations regardless of weather conditions. The construction apparatus is sufficiently resistant to earthquakes.
