Methodology of traditional working of construction timber for structural repairs of historical buildings
Kloiber, Michal ; Růžička, Petr ; Tippner, J. ; Kunecký, Jiří
The publication deals with a methodological description of traditional (manual) wood working for structural measures in repairs of historical buildings. The methodology includes the results of experimental testing performed during timber logging in various seasons (winter, spring, summer), results for different ways of working (cutting, splitting, hewing, and combination of hewing with floating), results of verifying the elimination of growth (residual) stresses in wood selection and working (selection of wood without natural defects and intentional interventions during working). The resulting methodology meets the protection standards of cultural heritage, in particular the requirement to minimize interference with the original material, while using the original working technology for newly incorporated elements including material selection. The methodology describes the prerequisites for use and the necessary marginal conditions, material selection, handling and storage of logs, woodworking technology (hewing, splitting, and cutting), but also storage of worked elements until the actual structural repair, while presenting the version of minimum interference with the original material using traditional (manual) working of timber on specific examples of structural elements.

Longitudinal log splitting in repairs of timber structures
Kloiber, Michal ; Hrivnák, Jaroslav ; Bryol, R. ; Tippner, J.
The range of technologies used has lacked a description of the traditional longitudinal log splitting, which was often used in order to utilize the maximum possible volume of timber extracted for constructions (especially rural timbered buildings). Longitudinal splitting supports carpentry sustainability as well as allows for accurate replication of the original elements (in dimension, shape, technology). Therefore, the research focused on the design of a procedure practically usable and applicable in the common practice for repairs of timber structures, especially historical monuments. Such a procedure is longitudinal splitting using wedges (metal and wooden) and mallets. The aim of the heritage conservation procedure was to practically describe the technical solution, the technological procedure of longitudinal log splitting allowing the use of hand tools only. The procedure respects the protection of cultural heritage standards, in particular the requirement to minimize interference with the original material, while retaining high accuracy of reproduction of the original properties of structural elements.
