A building assembly system for fabricating a multi-story building is described, wherein the building includes a vertical support core arranged on a base. Lift jacks are arranged between a top portion and a bottom portion of the vertical support core, and a reusable bridle is suspended from the plurality of lift jacks and slidably arranged on the vertical support core. A floor plate is assembled onto the bridle at an assembly level that is proximal to the base. The plurality of the lift jacks are operable to lift the bridle and the assembled floor plate to a design elevation on the vertical support core, and are operable to lower the bridle to the assembly level on the vertical support core after the floor plate has been secured to the vertical support core at the design elevation.

The invention is a method to build and erect super high rise buildings with a completely new concept of civil engineering, which is based on concept and method of building of vertical columnar structures by multi stacking of columns using hydraulic suspension and elevator arm system, and then strengthening them with concrete. This is followed with building of gateway support structure around vertical columnar structure and central core to stabilize the high rise building. Next stage is the building of horizontal steel framework platforms at ground level and elevating them by central core elevator and cable hoist system. The passage of horizontal platforms through gateway structure is conducted by alternating opening and closing of gates. The process enables to populate the vertical columnar structures with horizontal platforms, which are then inter locked with vertical columnar structures and central concrete core wall Finally the steel framework platforms are strengthened with concrete.

The present disclosure relates to a construction process, the so-called Zaina process, which was designed to industrialize the construction of buildings. The Zaina construction process operates like an industry that receives raw materials and transforms them into a product; it establishes an analogous vertical production line, the end product of which is a building. It is an industrial process implemented at the delivery site of the product, that is to say, the building.

A top-down construction method for a multi-storey basement with a full steel structure is provided, including: S1, constructing a diaphragm wall permanent structure; S2. conducting an open excavation, then constructing a first layer structural beam and slab; S3. conducting an underground excavation on an underground second layer earthwork, then constructing structural beam and slab and vertical shear wall on underground first layer; S4. excavating earthworks from an underground third layer to an underground N?1 layer, and constructing structural beams and slabs and vertical shear walls; S5. conducting the underground excavation on an underground N layer earthwork, and constructing a two-span structural steel beam; S6. conducting the underground excavation on earthworks of bottom plate layer, constructing remaining structural beams and slabs and vertical shear wall; S7. conducting the underground excavation on earthworks of bearing platform and water collection well; S8. constructing earth intakes of the podium and the basement.

The present invention integrates the use of pre-manufactured structures with minimal on-site installation and lift-slab construction to achieve the construction of multi-story buildings. The pre-manufactured structures are designed to be readily integrated with both horizontal and vertically adjacent building components, including lift-slab components, so that multiple building stories may be readily and securely stacked, one on top of the other. The present invention advantageously permits top-down lift-slab construction for multi-story buildings. The present invention also provides for the development of flexible design plans for institutional, residential, office and other types of buildings. The present invention advantageously provides for easier, more efficient, faster, cheaper, safer, higher quality and more consistent, environmentally advantaged, energy-efficient, easier to maintain, intelligently designed, and customizable multi-story building construction.

A multi-story building floor support system is basically provided with a receptacle and a first support member. The receptacle is configured to be embedded into a building core. The receptacle includes a first chamber, a first support plate and a second support plate. The first chamber has with a first insertion opening. The first support plate protrudes from a top surface of the first chamber. The second support plate protrudes from a bottom surface of the first chamber. The first and second support plates are structured to retain the receptacle inside the building core. The first support member has a first end section and a second end section. The first end section is configured to be inserted into the first receiving opening of the first chamber such that the second end section projects outwardly from the first receiving opening of the first chamber.
