    • Disclosed is a honeycomb structure capable of preventing the generation of cracks in buffer portions and preventing the honeycomb structure from being divided when an operation (regeneration) of burning collected particulate matters is repeated. A honeycomb structure 100 includes a plurality of honeycomb segments 4 having partition walls 2 separating and forming a plurality of cells functioning as fluid passages and extending from one end surface of each segment to the other end surface thereof, and protruding walls 3 which are provided so as to protrude externally from partition walls 2a forming side surfaces 5 of the segments and which extend from one end of each segment to the other end thereof in a central axis direction. The plurality of honeycomb segments 4 are arranged adjacent to one another so that the side surfaces 5 of the honeycomb segments face each other with a predetermined distance being left therebetween, each buffer portion 11 is disposed between the adjacent honeycomb segments 4 to join the honeycomb segments 4 together, and an outer peripheral portion 13 is disposed on an outermost periphery 12 of the plurality of joined honeycomb segments 4.
    • 公开了一种蜂窝结构,其能够防止在缓慢部分产生裂纹,并且当重复收集的颗粒物质的操作(再生)时,防止蜂窝结构体分裂。 蜂窝结构体100包括多个蜂窝段4,隔壁2分隔并形成多个用作流体通道并且从每个段的一个端表面延伸到另一端表面的单元,并且突出壁3设置成 从分隔壁2a的外侧突出出来,形成分段的侧面5,并且从中间轴线方向的每个段的一端延伸到另一端。 多个蜂窝片4彼此相邻布置,使得蜂窝片的侧面5彼此面对预定的距离,每个缓冲部11设置在相邻的蜂窝片4之间,以将蜂窝片段 4一起,外周部13设置在多个蜂窝结合体4的最外周12上。
