论耍头拟昂现象与六铺作的缺失——以晋东南地区为例

A Study on Overhanging Bracket-End in the Shape of Inclined Arm and the Absence of Six-Tier Bracket Set as Exemplified in Southeast Shanxi Province

耍头自产生伊始,最先模拟下昂昂尖的形态,其后随着梁架与铺作节点的改变,逐渐缩短并丧失结构功能;同时,在使用昂形耍头的木构中六铺作斗栱亦集体缺失。本文从构造做法和外观形象两条线索出发,以遗存数量丰富且时代接续的晋东南地区为例,诠释耍头拟昂与弃用六铺作两种现象间的内在关联,以期揭示构件选型与构造节点设计间的连带性问题。

Overhanging bracket-ends simulated the shape of the end of inclined arm ever since existence, while the length was reduced with no structural function as the joints of beams and bracket sets were changed, and six-tier bracket sets are collectively missing in the buildings with inclinedarm-shaped overhanging bracket-ends. Taking existing buildings in Southeast Shanxi Province as examples, this paper attempts to discover coherent connections between the simulation of bracket-end as inclined arm with the absence of six-tier bracket sets in terms of construction techniques and appearance as the two sets of clues. It aims to reveal the collateral phenomenon between the formal selection of components and design of joints.
