摘要:
At least one hollow core tower (preferably of a rectangular construction) is constructed from a foundation to a preselected floor supporting height. The tower is preferably joined at the top and slotted vertically along at least one sidewall from the base of the tower to a partial height of the tower. Preferably the tower is slotted along opposed sidewalls to form opposed C-shaped sections confronting one another at the slots. After at least the lowest and ground adjacent portion of the tower is constructed, floors are built about the tower at or near ground level. The floors include a section extending into or across the tower at the slot or slots which preferably includes a cantilevered or spanning horizontal floor strengthening beam. Typically, the floors are constructed and stacked one on another at their ground level with the bottom floor built first and lowest, and the top floor or roof built last and highest at the top of the ground supported stack. Floors with curtain walls preferably attached at ground level are successively raised and fastened to the tower with the top floor raised and fastened first, and the lower floor raised and fastened last. With one or more of the floors in place, each floor at or near its section adjacent the tower is fastened to the tower sides to cross brace the tower at the slot. The floor section immediately surrounds the tower and locks the opposed tower sections against outward deflection or dynamic movement. A bridge across the tower at each floor simultaneously forms an interior lobby floor having on either side building service shafts, such as those required for elevators, fire stairs and conduits.

A reinforced concrete floor is constructed from a continuous slab defining a major and planar supporting surface. The continuous slab is folded at at least one beam defining path across its planar supporting surface and preferably includes a right angle grid of such folds with downward peripheral folds at the slab edges and downward V-sectioned folds to interrupt the major and planar supporting surface. By maintaining a constant vertical slab thickness and keeping the angle of the folds between 30.degree. and 60.degree. with respect to the major supporting surface, it is possible to nest and even construct a continuous stack of floors having identical overlying structural members and dimensions, such as the structurally and dimensionally repetitive overlying floors of a high-rise building. Moreover, when a nested stack of such floors is constructed or placed, the top floor of each nest in sequence at its beam defining folds can have beams placed immediately prior to lifting, while underlying floors await exposure to the top of the nest and placement of their beams in turn. Preferably, either cast-in-place or precast beams are placed from above the exposed floor into and fastened along the folds. This simultaneously completes the flat supporting surface of the floor as well as provides any needed and additional structural rigidity in the plane of the floor. Where the floors are nested at the base of a building vertical structural member, which can preferably be one or more central supporting towers, a building process results. Floors formed of folded, nested and stacked slabs are in sequence commencing with the top building floor and ending with the bottom building floor completed. Completion occurs by the placement of beams and/or flooring and sequentially raising and supporting each floor from the vertical structural member to provide a high-rise building.

A concrete floor is constructed at least partially about a supporting hollow core tower. The hollow core tower, which preferably includes a rectangular section, closely conforms to the border of the floor at the elevational outside section where the floor is fastened. The floor at its edge, immediate the tower sides, is provided with beam defining folds preferably bent down at an angle in the range of 30.degree. to 60.degree. from the major plane of the floor. At least one beam at each tower and at least two non-linearly aligned beams at each floor are nested at the floor-tower interface, typically below the major supporting surface of the floor. The tower sidewall at the floor is transpierced and threaded to receive a tension support member angularly depending downwardly and outwardly from the inside of the tower to the outside of the tower. Likewise and in registry with apertures transpierced in the tower, the beam at the tower inside includes apertures extending angularly downward. Those apertures extend through the floor fold at the tower outside. When the floor is raised to its full supported height, bolts are threaded through tower sidewalls, horizontal beams and slab folds and fastened at opposite ends to receive tension. The resultant fastening provides a vertical support to the floor through and at the beam as well as a friction support of the floor to the tower sidewall.
