nakazonae 中備
KEY WORD : architecture / general terms
Also written 中具. Secondary or intermediate supports placed in the interstices between the bracket complexes *tokyou 斗きょう a top of the pillars. The most common types of support are bearing-block capped struts *kentozuka 間斗束, frog-leg struts *kaerumata 蟇股, or plectrum or spatula-shaped struts *minozuka 蓑束. These struts are set between head tie beams *kashiranuki 頭貫, and wall purlins *tooshihijiki 通し肘木. Originally these struts were added to strengthen the roof frame above. They were necessary from the 7c to the end of the 10c, and continued to be a characteristic of the Japanese style *wayou 和様. However, with the invention of the hidden roof *noyane 野屋根, at the end of the 10c, the struts had lost much of their structural function and became more and more decorative.
