Reciprokt tak i rundvirke. En hantverksinriktad studie i geometri och utförande

Abstract

Reciprocal roofs have, due to their unique appearance and possibility for large spans without the need for central support, gained popularity over the last 30 years. A variety of construction methods have been presented, with a varying degree of accuracy, and those that hold higher standards (i.e. those that take all the parameters into consideration and leave nothing to chance) exclusively deals with square-cut timber. In working with roundwood timber one has to adapt the marking and layout procedures to another set of prerequisites than those used in working with conventional square-cut timber. This study aims to bridge the gap between available published knowledge about the geometry in reciprocal roofs and the working methods applied in roundwood timber framing. The practical experiment accounted for is the full-scale construction of a hexagonal reciprocal roof with roundwood timber executed in sections and an investigation of the different problems posed by this method of construction.
