An Analysis of Contributory Factors in the Formation of Carpentry Latticework

Gerehchini (latticework) is one of the most prominent patterns used in Iranian handicrafts and buildings. It should not be considered as a mere visual pattern, but in principle as a solution to solve executive challenges. Carpentry latticework is a type of geometrical pattern used in making fences, doors and most of all latticed windows. Due to the vulnerability of wood material, especially owing to its proximity to the open air, as serious study of such structures have to be carried out. An analysis of latticework and the tradition of making such works can now be done by present masters and the few images and examples remained from the traditional Iranian architecture. In this article, an attempt is made to explain the strategic reasons for using this type of pattern by examining the various aspects of the factors affecting the formation of this type of lattice.The purpose of this study is to identify the factors affecting the carpentry latticework used in latticed windows and to explain the reasons for the difference between such a lattice and other related types. Defining the nature of carpentry latticework depends upon understanding the way it is made. The function of windows, features of wooden constructions and construction methods, basic knowledge of flat geometry, visual aesthetic development of artists and architects are among the factors influencing the formation of carpentry knots. Reviewing these cases by field and library studies with a descriptive-analytical and modeling approach, this article is done with the purpose of having an accurate representation of the carpentry latticework and making an analysis of the feature of this type of lattice. One of the results of this research explains three factors, i.e. function, appearance and technology in the formation of the mentioned lattice. Incidentally, the role of different factors in the formation of this type of lattice is examined by looking through a detailed study of its construction.
