Extended Wooden Panels for Flooring and Cladding of Buildings

Introduction. The development of the construction industry in Russia involves both emerging technologies and materials and traditional construction methods. One of the well-known tools in this country is wooden housing construction. Apartment buildings are being built from wooden CLT panels, glued timber, beams made of unidirectional veneer, etc. are commonly employed. Modern architecture seeks to create large open spaces for free planning. In wooden buildings, it is not always possible to organize such spaces due to a limited length of lumber being produced. Studies aimed at designing extended panels from wood are thus gaining momentum. The aim of this study is to develop new designs of wooden panels for cladding and flooring of buildings from standard lumber, plywood and oriented strand boards with spans exceeding the standard length of boards, to identify the limits in the load-bearing capacity of such panels, as well as to conduct their geometric calculation.

Materials and Methods. Two types of box-shaped panels made of wooden planks, plywood and/or oriented strand boards are considered. The load-bearing capacity of the suggested structures is estimated by means of both traditional methods of material strength and computer models.

Research Results. The design of extended panels is described differing from the known overseas analogues and is free from the inherent disadvantages of the latter. Geometric calculation of the suggested structures is performed. The rational size ratios of the sizes of boards that make up the panels are identified. Design limitations for individual elements of products are established. Computer models of the panels are designed and employed in order to identify the applicability limits of the suggested structures.

Discussion and Conclusion. As a result of the research, new designs of wooden panels for flooring and cladding of buildings with possible spans exceeding the standard length of lumber and made with no use of costly materials have been developed. The simplicity of the design makes it possible to organize manufacturing of products in small-size industries with complex and costly equipment involved. The panels can be employed for long open spaces in wooden buildings and structures for a broad range of purposes.
