Title of the articleThree-layer corrugated board for the low-rise building
Abstract.The article presents a structural element and a method of manufacturing a three-layer profiled wooden wall beam, consisting of the exterior wood boards with a thickness of 30-45 mm with final finishing, and an inner layer of insulation made of wood-fiber plates. As the cross sectional shape of the beam taken existing profiles laminated boards for walls. For bonding all layers use polyurethane resin. Grading lumber is performed with inserted insulation, which improves the accuracy of manufacture. The advantages of the proposed technical solution of three-layer beams is the lack of an impermeable adhesive joint according to the thickness of timber that circulates steam through design, using only natural materials (wood, polyurethane resins) for the manufacture, high manufacturing precision, small deformation of the shrinkage of the finished structure, high heat transfer resistance and heat capacity, which reduces heat loss and also reduce the cost of heating and air conditioning in comparison with other designs, reuse of waste in manufacturing. The disadvantages include higher requirements for quality of raw materials for the manufacture of face layers and for the insulation boards, as well as high demands on the quality of installation.
Keywords.profiled timber, wood fiber insulation, technology for the production of timber.
