Robotization of production of wooden panel structures and construction with their application

Introduction. It is necessary to ensure that by 2030 the Russian Federation is among the top 25 leading countries in the world in terms of robotization density. The solution of this most important task should contribute to increasing the competitiveness of the Russian industry in the global market and accelerating the technological development of the country. Robotization has been identified as one of the directions of development of wooden house building. The condition for the introduction of automation and robotization is the creation of a continuous digital environment, starting from design, manufacturing, operation and disposal of building structures, covering all stages of the life cycle of construction products.

Materials and methods. There is an active growth of scientific papers devoted to robotics in the construction sphere.  In terms of the number of published papers Russia ranks 6th out of the total number of 61 countries considered. The efficiency of construction robotization is assessed from the point of view of economic efficiency of construction as a long-term investment process. The introduction of robotization depends to a large extent on the type of materials and production operations used. Currently, specimens of a new generation of domestic automated and robotized construction and assembly equipment are being developed and introduced into construction. Construction using wooden structures is one of the most promising areas for robotization.

Results. The experience of robot production of wooden arch coverings made of standardized calibrated solid timber bars of Japanese cypress wood with the use of single-type joints is considered. On the basis of production indicators of the operating enterprise LPC “Almas” LLC in Yakutsk the estimation of the reduction in the cost price of wooden panel constructions by 17.48 % was made when automating their production. An expert assessment of labour cost reduction in construction and installation works of large-panel buildings, as a correct analogue of a multi-storey building made of wooden CLT-panels, by 25 % in machine-shifts and man-days was carried out.

Conclusions. A prerequisite for the implementation of robotization is the creation of BIM of a high level of detail. The introduction of automation and robotization in construction with wooden structures has an effect on the stages of the factory production process and construction and assembly work.
