Definitions

  • This invention relates generally to the field of prefabricated modular building systems for housing construction and construction projects in general.
  • U.S. Pat. No. 8,397,441 relates to buildings made up of recycled intermodal containers, sometimes called maritime containers or ISO containers.
  • containers require extensive modifications, such as cutting or removing sidewalls in order to allow for windows or doors.
  • the construction is limited to a width of 2.44 m and a length of 6.06 m or 12.19 m, which in turn limits the room size to fit within these dimensions.
  • prefabricated modular building systems are attractive because simplified and repetitive assembly of parts offers the possibility of erecting a construction project quickly while drastically reducing waste, losses, and multiple learning curves common to conventional construction.
  • quality and versatility of the “prefabricated” buildings is lower to that of buildings manufactured conventionally. This is partly due to the materials used, such as cargo containers, which has created a stigma associated with the construction term “prefabricated modular building systems”.

No. 7,665,250 addresses structures assembled from a combination of modules and uses, for the combination of said modules, module framing blocks, corner arch blocks, and other types of elements interlocking with corner blocks, and central blocks, which makes this system and many others in prior art complex systems, given the amount of necessary pieces to form a module.
  • This invention overcomes the disadvantages and limitations associated with several floors, modular construction and conventional construction methods to produce an energy efficient structure that can be built on a tight schedule, low cost and continue operating at very low maintenance costs, allowing for flexible construction with few elements to form a module and also allowing quick assembly for multiple purposes with resistant elements.

  • the connecting Means joining horizontally and vertically the structural frames are geometrical assemblies, located in the elements edges, which connect the pieces together, stiffening them by friction.
  • the connecting Means joining horizontally and vertically the structural frames are geometrical assemblies by a chamfer ( 14 ) in the edge of of the structural frames with an angle a range from 15° to 75° preferably 45°.
  • the connecting Means joining horizontally the structural frames are flat bars in “Z” ( 27 ), which are fixed to the upper structural frames through bolts, screws or welds.
  • the bonding sheet has three surfaces: an upper vertical ( 28 ), a horizontal ( 29 ) and a lower vertical ( 30 ).
  • the preferred joint angle is 90° and has a range between 0° and 180° measured from the surfaces of the structural structural frames that are attached.
  • the preferred attachment angle is 90° and have a range between 0° and ⁇ 180°, also measured from the surfaces of the structural structural frames which these flaps link.
  • the fins forming the bonding sheet have a preferred caliber of 2 millimeters, with a range between 0.5 and 10 millimeters. They can be located in each one of the structural structural frames, to increase the system rigidity. The preferred location of these elements is at the outer edge of each structural frame.
  • the joining sheets may also be at the joining of two structural structural frames, or at any part of the surface of the horizontal slabs of the framing frames.
  • the bonding sheets may be attached to the structural frames through bolts, flat bars, or be embedded in the emptying process.
  • the angles of the joints between the structural structural frames are set according to the geometry defined from the architectural designs.
  • the dimensions of one of these flat bars referring to FIG. 16 is for example In its upper vertical fin ( 28 ), the preferred length of the flat bar in “Z” is 15 centimeters in height. This dimension has ranges between 2 and 30 centimeters in height. On its horizontal flap ( 29 ) In its lower vertical flap ( 30 ), the preferred length of the flat bar in “Z” is 15 centimeters. This dimension has a range between 2 and 30 centimeters in length.
  • the preferred caliber is 2 millimeters and can be varied in a range of 2 to 10 millimeters, according to the structural calculations performed for each case.
  • the dimensions are directly proportional to the thickness of the vertical slabs in the different heights of the system, and for example 2 millimeters more on each side to guarantee the assembly between the flat bars and the slabs of the structural frames.
  • the connecting means joining horizontally and vertically the structural frames are geometrical assemblies formed by supports ( 31 ) between slabs of the structural frame.
  • the connecting means joining horizontally and vertically the structural frames are a flexible element such as neoprene, rubbers or the like located on the edges of the vertical and horizontal slabs of the structural frames, and they finish adhering by the pressure that is made to join the structural frames together.
  • the horizontal connecting means between the structural frames is a flexible element such as neoprene, rubbers or the like ( 32 ). These elements are installed on the edges of the vertical and horizontal slabs of the structural frames, and they finish adhering by the pressure that is made to join the structural frames together.
  • waterproof elastic gaskets covering a portion of the edge section of a structural frame.
  • the flexible element ( 32 ) is installed between the structural frames with a thickness of between 5 millimeters and 10 millimeters. These seals are located in the edges of the horizontal and vertical structural slabs and adhere to them by the pressure that is made to join the structural frames.
  • continuous structural elements such as post-tensioning metal wires ( 33 ) which are used inside the structural frames in the longitudinal or transverse direction through ducts with a diameter, for example of 1 ⁇ 2′′, and through the tensions made, join the structural frames with each other.
  • the support structure is constructed with the arrangement of the structural frames assemblies ( 34 ).
  • the structural frames are made in such a way that there is an empty space ( 35 ) i.e. Habitable spaces and empty spaces that form for example courtyards between two sets of structural frames and thus form a living space.
  • the arrangement of the structural frames is made in such a way that at the same level or in height there is a sequence of sets of structural frames and empty spaces. Structural frame assemblies that are installed on other structural frames also continue the sequence in height of structural and empty frame assemblies. In this way, the structural elements necessary for the construction of a building leave spaces that can be used as living spaces.
  • a cover ( 36 ) is added between some sets of structural frames, thereby forming a new living space.
  • An open section structural frame can also be added where the geometric shape of its cross section in cut of the open section structural frame is an open perimeter geometry formed of open polygonal lines in “U” shape ( 37 ) supported on another structural frame, forms a new living space.
  • the voids ( 6 ) between the structural frames are covered with a cover ( 36 )
  • the facades which are the front spaces of the structural frames and that are delimited by the vertical and horizontal slabs.
  • the facades, interior divisions and roofs are constructed with non-structural elements with various architectural forms and structural or non-structural elements with materials according to the weather, the provision of economic and material resources, or cultural tradition such as: metal sheets, masonry in brick or concrete, concrete emptied or prefabricated soil, metal, glass, wood, dry-wall type light modular divisions or similar, natural or synthetic agglomerates, polymers, among others.
  • At least one cover in the empty left by the installation of the structural frames located on the top floor of the building, at least one cover will be installed which will carry the rainwater through channels to be carried out.
  • Said cover can be curved, straight or sloping lines or combinations of the above and has a slope for example of 2% and conduits towards channels of rainwater collection and can be metallic, emptied in concrete, constructed with brick, wood, clay tile, concrete blocks or textile materials.
