Definitions

  • This invention relates to a reinforced concrete structure for a house and its design method.
  • the term "house” includes both detached houses and apartment buildings.
  • the structure of columns and beams (for example, the thickness of the columns and beams, and the position and number of reinforcing bars arranged inside them) is almost always different for each column or beam, and it is more common to adopt a complex structure in which the structure of columns and beams is different for each column or beam, in order to achieve both the fulfillment of the safety performance required for the building after construction and the reduction of the cost of construction materials as low as possible.
  • structural designs have become too complicated, and in most cases, they are performed using dedicated software installed on a computer, and the dedicated software is created using the approach described above.
  • structural design is extremely complicated. This causes other problems.
  • the work done by structural designers is extremely complicated, and therefore the time required for structural design itself is long and the cost required for structural design is often relatively high.
  • the structural design of even a detached house with a reinforced concrete frame takes about two months and costs 500,000 to 1,000,000 yen.
  • the materials needed to build the building and the number of construction steps (which relate to the labor costs required during construction) are not finalized, and so the cost required to build the building cannot be estimated.
  • structural design could be simplified, for example by reducing costs, it could potentially resolve some of the issues preventing the widespread use of concrete-framed homes.
  • structural design has the objective of "generally designing the foundations and framework of a building economically while satisfying safety performance so that it can withstand various loads," and where it is believed that the correct approach to achieve this objective is to "achieve both the satisfaction of the safety performance required for the building after construction and the reduction of construction material costs as much as possible by adopting a complex structure in which the structures of columns and beams are different for each column or beam," the idea of simplifying structural design does not even exist. Therefore, at least at present, no realistic means have been proposed to make structural design cheaper.
  • the present invention aims to propose a technology that simplifies structural design, making it possible to complete the design in a short time and at a low cost, and in some cases, even reducing the costs required to build a house.
  • the technology is concerned exclusively with reinforced concrete frameworks for houses, or design methods.
  • the invention proposed by the applicant to solve the above problems will first be outlined.
  • conventional structural design is complicated.
  • the reason why structural design becomes complicated is, for example, to ensure the strength of the building or house provided by the columns and beams by giving only the minimum necessary strength to the components of the rigid frame structure, such as columns and beams, while minimizing the cost of construction materials.
  • the simplest shape for a rigid frame structure in which the load of a building or house is supported by columns and beams is a rectangular parallelepiped frame, which includes four beams each extending in the horizontal and mutually perpendicular x- and y-directions, and four columns extending in the vertical z-direction.
  • a frame with a specific shape as a reference frame
  • adjacent reference frames columns and beams that overlap each other are combined into one. This makes it possible to construct a rectangular parallelepiped frame with a certain degree of freedom.
  • a reinforced concrete structure including a new frame obtained by arranging X pieces of reference frames including the above-mentioned standardized columns and beams in the x direction, Y pieces in the y direction, and Z pieces in the z direction can always support the load of a house including it, then a reinforced concrete structure including a new frame obtained by arranging X pieces of frames (quasi-reference frames) in the x direction, Y pieces in the y direction, and Z pieces in the z direction, which conform to a reference frame that is smaller in at least one of the x direction, y direction, and z direction than a reference frame equipped with columns and beams similar to the standardized columns
