Definitions

  • the invention relates to a method of constructing building units using composite materials and adhesives, for varied purposes and functions, including low-cost housing.
  • a house is one of the essential needs of the people.
  • Conventional houses are usually made of wood, cement, iron bars, and GI sheets, among other construction materials. These materials are often expensive and the construction of a house with the said materials is complex and takes a long time and requires many workers. All these cause difficulty in the construction of decent dwellings for Filipino families.
  • the ideal for any building unit is that it will be there to stand the test of time and exposure to the elements so as to serve its purpose and need for a long, long time.
  • a number of basic steps may be identified in constructing a building unit in the conventional way. Firstly, the ground at the site of the building unit should be cleared and levelled before the next step of pouring the foundation. Foundations often consist of poured concrete with steel rods. Since concrete isn’t waterproof, this should be sprayed with a waterproofing substance. Subsequent steps become more and more complex and labor/material-intensive, such as, framing, setting up plumbing, electrical, ventilation system, adding insulation and drywall, interior and exterior finishes, and installing fixtures and flooring. Simplified and low-cost houses, as well as the method of constructing the same, already form part of the prior art.
  • CN206090841 titled “Fast Installation Room Structure”, published on 12 April 2015, relates to a quick-assembly house structure comprising a steel modular frame and a plurality of modular cement boards wherein said steel modular frame comprises a top beam, a vertical column, a bottom frame, and a foot column; the steel modular frame adopts a channel steel welding structure, the lower end of the stand column is vertically fixed on the bottom frame, and the upper end of the stand column is connected with the top beam; the foot column is located below the bottom frame and is vertically fixed to the bottom frame.
  • Said modular cement board comprises a channel steel frame and a fiber cement board wherein the channel steel frame is of a rectangular frame structure and the fiber cement board is fixed in the channel steel frame.
  • Said cement board comprises aerated concrete fiber board, a thermal insulation board, and a high-pressure cement fiber board which are sequentially attached to each other.
  • CN206267295U titled “Big Board House”, published on 20 June 2017, relates to a large board room with walls, doors, windows, and roof panels wherein said room has no pillars, steel frame, mold beam or purlins.
  • the foamed cement board has a strong increase in strength after having a steel channel, steel wire, a mesh cloth, and a high strength mortar, and steel wire.
  • JP 2000129720 discloses a low-cost house building method that includes constructing a foundation that an individual concrete footing at the periphery in which a foundation for a plurality of framework columns are erected and mat foundations for an external wall foundation connecting the individual footings and within an earthen floor surrounded by the external walls are integrally fixed, a field welding process for a heavy square steel pipe column and a beam in which a framework is erected on the individual footing, and a process using a light weight cellular concrete board for an exterior wall and a reinforcing steel frame for an opening.
  • CN 200710034832.5 discloses to a method for rapidly assembling a low cost energy-saving house with precast columns, beams and slabs comprises the steps of preparing house columns, beam molds and built-in reinforcing steel bars or profiled steel bars, pouring concrete grout into the molds, high-speed rotating in a centrifuge, curing, and demolding to obtain precast reinforced concrete columns and beam components; and inserting the precast columns on a cup foundation element, passing the precast beams through the preformed pores on the precast column, lapping precast floor slabs on the precast beams, and embedding wall slabs inside the embedding grooves of the precast beams, so as to form the major structure of the rapidly assembled low-cost energy-saving house.
  • JP 2011154728 relates to a simple building construction that comprises: quadrilateral annular frame units each of which consists of four wooden frame bars connected to each other at respective end parts thereof by joint metal fittings in an orthogonal state; structural plywood plates which are fixed on the top surfaces of a plurality of annular frame units and the exterior surfaces of both side faces opposing to each other to connect and integrate between the wooden frame bars, in the state that the plurality of annular frame units are arrayed in parallel at predetermined intervals in the thickness direction; and floor boards which are fixed on the floor surfaces of the plurality of annular frame units.
  • the object of the present invention is to provide an easy and cost-effective method for constructing buailding units for varied purposes and functions, in particular, a simplified and low-cost house unit.
  • the present invention relates to a method for construction of a building unit characterized by the use of fiber cement-plywood composite boards and laminated veneer lumber as parts, and the use of construction adhesive to form and fasten the said parts.
  • the invention also relates to the building units, such as a house, built through the said method. With the use of only adhesive for fastening the parts of the house, the construction becomes simple and cost-effective.
  • the said fiber cement-plywood composite board is used as the main construction material for the low-cost house.
  • the fiber-cement part of the panel faces the outside of the house due to its weather, fire, and termite-resistant properties while the plywood component provides good insulation and may provide a wooden interior finish.
  • the house As the structure is predominantly made of wood and fiber cement, the house is perfect for the weather in the tropics as it provides cooler ambient room temperature and better ventilation. The load-bearing capacity of the structure is superior considering that it is made out of light materials.
  • the 16ft x 16ft layout is based on the structural integrity of the material, the economy of space, decency, security, and comfort at a very affordable price.
  • the house uses laminated veneer lumber (LVL) to combine the best features of cement and wood resulting in benefits of strength, weatherability, fire and termite resistance.
  • the laminated veneer lumber serves as the framework where the plywood-fiber cement panels are glued at the joints. The use of laminated veneer lumber is because it is better quality than lumber from sawmills. It does not warp and weathers better than lumber.

Abstract

La présente invention concerne un procédé de construction d'une unité de construction caractérisée par l'utilisation de panneaux composites de fibrociment-contreplaqué et de bois en placage stratifié en tant que parties, et l'utilisation d'un adhésif de construction pour former et fixer lesdites parties. L'invention concerne également les unités de construction, telles qu'une maison, construites selon ledit procédé. Avec l'utilisation d'un seul adhésif pour fixer les parties de la maison, la construction devient simple et économique. La capacité portante de la structure est supérieure en considérant qu'elle est réalisée en matériaux légers. La disposition de 16 pieds x 16 pieds est basée sur l'intégrité structurale du matériau, l'économie d'espace, la décence, la sécurité et le confort à un prix très abordable.
