A STUDY ON THE METHOD OF ERECTING THE PRINCIPLE TOWER OF NAGOYA CASTLE IN HOREKI PERIOD

The Principal Tower of Nagoya Castle was repaired on a large scale from 1752 to 1755. This paper evaluates and analyzes the Principal Tower based on historical drawings and specifications, which explain the repair of the main body of castle tower. The northern and the western parts of the first and the second layers on the top of the stone wall of the Principal Tower were dismantled before the stone wall was dismantled. Also, the builders cleverly applied a system of levers. Then the subsidence and the inclination of the Principal Tower were fixed logically and systematically using the system.�

A STUDY ON THE DISMANTLEMENT REPAIR OF STONE WALL OF THE PRINCIPAL TOWER OF NAGOYA CASTLE IN HOREKI PERIOD

The Principal Tower of Nagoya Castle was repaired on a large scale from 1752 to 1755. This paper evaluates and analyses the principal tower based on some drawings and specifications, which have explained about the leading frame that gives a base line on the stone wall of the tower. Besides that, this paper is also addressed to clarify the dismantlement repair process and its area. Basically, the dismantling and piling up were gradually done within the appropriate range on the North side and West side of the stone wall, and the new window had been installed.

DIMENSIONAL RELATION BETWEEN RAFTER PLACEMENT AND BRACKET COMPLEX OF “NON-ROKUSHIGAKE” ARCHITECTURE

As for the relation between the rafter placement and the bracket complex, Rokushigake architecture, which is the combination of the outer surface of each block and the outer surface of the two rafters, is well known. However, there are quite a few non-Rokushigake Japanese shrines and temples designated as national treasure or important cultural properties. This paper will analyze the dimensional relation between the rafter placement and 3-on-1 bracket complex among the non-Rokushigake architecture. Consequently, it became clear that the outer surface of three-block bracket arms or its center are matched systematically with the inner surface of the rafter above and its center or the outer surface from the six-rafters placement to three-rafters placement.
