    • BACKGROUND Field of the Invention
  • The present invention relates generally to building construction, and particularly to an improvement in reinforced concrete with automated self-installing concrete formwork.
    • Description of the Related Art
  • Plain concrete does not easily withstand tensile and shear stresses caused by wind, earthquakes, vibrations, and other forces and is therefore unsuitable in most structural applications. In reinforced concrete, the tensile strength of steel and the compressive strength of concrete work together to allow the member to sustain these stresses over considerable spans. Steel is embedded in the concrete in such a manner that the two materials act together to resist those outside forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure. The invention of reinforced concrete in the 19th century revolutionized the construction industry, and concrete became one of the world's most common building materials.
  • Concrete has low tensile strength but very high compressive strength. Reinforced concrete is created when concrete is combined with steel reinforcing bars that have high tensile strength. The two materials combined act together to resisting forces in a better way than each does by itself. The steel reinforcing bars that are used for this purpose are called “Rebar” as shorthand. Rebar cages are longitudinal or vertical bars that are laid out with uniform spacing and have other sets of rebar placed in a transverse position and attached with ties, clamps or welds. Once rebar cages are installed on a construction site, concrete formwork is assembled to hold concrete in place until it cures enough to hold its own weight. Traditionally, formwork was made out of plywood that is installed by hand, or by reusable metal or plastic concrete formwork that is set up manually, and taken down manually.
  • The prior methods of setting up concrete formwork in construction are heavily labor intensive, slow, and in the case of formwork made with plywood, not environmentally friendly.
  • A U.S. Pat. No. 9,683,361B2 prefabricated assemblies which are assembled on a construction site to provide a permanent concrete mold with integrated structural reinforcement and structural splices for cast-in-place concrete structures. The invention enhances the quality of the cast concrete structure while lowering the cost of construction and construction time. Described herein is a column form assembly, a column closure panel assembly, a beam form assembly, and a slab form assembly which are used to construct cast in place structurally reinforced concrete columns, beams, and floor slabs with minimal form work and construction site logistics. Also described herein are a method of assembly of said structures and a method of fabricating said assemblies.
  • U.S. Pat. No. 10,227,785B2 provides a robotic casting machine (RCM) provides for on-site, or near-site casting and automated production of cast components, such as concrete modular, volumetric building components. The RCM includes stationary and mobile support structures, which can be positioned in a loading configuration, a casting configuration and an ejection configuration in which the cast volumetric component may be ejected from the mold. Tipping machines located beneath the cast component facilitate ejection, rotation and loading of the ejected module onto a transport surface for transport of the module. The support structures are constructed of prefabricated frames that may include at least one standardized section, which may be utilized on every project, and may also include a customized section, which may be provided to achieve desired dimensions of the cast module on a particular project. A casting process is provided in which a volumetric module is cast in a rotated orientation, in which the floor is cast with an initial vertical orientation, the transverse walls extend in a horizontal orientation, which is cast in vertical wall forms, and a longitudinal wall extends horizontally along the top of the mold. Modular, volumetric components created using the RCM and casting process are also described.
  • A U.S. Pat. No. 9,371,648B1 discloses concrete building structure and method for constructing a building structure which includes a first cross-brace section, including a plurality of pre-cast concrete blocks connected in series by at least one rebar; a second cross-brace section, including a plurality of pre-cast concrete blocks connected in series by at least one rebar, extending generally perpendicularly to the first cross-brace section such that the first and second cross-brace sections form a grid understructure; a plurality of channels encapsulating adjacent blocks from the first and second cross-brace sections, whereby the grid understructure includes channels into which concrete may be poured at a building site; each of the plurality of blocks positioned within respective channels; a plurality of pre-cast concrete slabs resting atop the blocks in the grid understructure; and poured concrete filling each of the channels and a space between adjacent concrete slabs to complete a generally flat floor of the building structure.
  • A US patent 20160160515A1 describes a construction systems for erecting building structures comprise a plurality of prefabricated interconnectable modular budding units, each unit comprising framing members and a plurality of nodes, each node situated for selective interconnection with other units, the nodes and the exterior dimensions of the frame conforming to ISO shipping standards such that each unit is transportable using the ISO intermodal transportation system, and such that when the units are interconnected, a building structure is formed.

  • A U.S. Pat. No. 8,151,537B2 A method of deploying a cooperating set of prefabricated structure comprises positioning a first prefabricated structure including a first shell and a first extension nested within the first shell, the first shell and first extension having corresponding frames that form channels communicating electrical wiring. The method further comprises positioning a second prefabricated structure including a second shell and a second extension nested within the second shell, the second shell and second extension having corresponding frames that form channels communicating electrical wiring. The electrical wiring of the first prefabricated structure and the second prefabricated structure connect so that the first prefabricated structure and the second prefabricated structure share a common electrical system.
  • An EP patent 0,032,421A1 on fiber-reinforced concrete comprising a concrete matrix including two kinds of short fibers (A,B) one being a short fiber (A) having a Young's modulus higher than that of concrete, the other being a short fiber (B) which has a Young's modulus lower than that of concrete a showing good adhesiveness to concrete. The said fibers are mixed in a predetermined ratio and are dispersed in the concrete matrix. A reinforcing material for concrete is also disclosed, such material consisting of a mixture of the fibers (A.B) as mentioned above.
  • It can thus be seen from the foregoing that several attempts have been made to provide different materials and strategies for assembling concrete formwork to speed up construction. However clearly, the need exists for an automated self-installing concrete formwork which allows buildings to be built faster and with less construction waste. Automated self-installing concrete formwork are capable of easy, fast, solid installation and can hold the significant weight of concrete and reinforced steel bar (rebar) while concrete cures enough to support its own weight. Furthermore, there is a need for an apparatus and method of manufacture for larger-scale precast concrete blocks which, is substantially automated, easy to use and clean, integrates casting and transportation functions, and is of moderate scale.
  • None of the previous inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed. Hence, the inventor of the present invention proposes to resolve and surmount existent technical difficulties to eliminate the aforementioned shortcomings of prior art.
