摘要： A connector for mounting a pipe member (P) having a spiral-shaped wall to a through hole (h) formed in a wall member (W), the connector comprises a bellmouth (1), a holder (2) and a waterproof packing member (3). The bellmouth (1) includes an engaging projection (13) which is formed on the outer periphery (12) of a cylindrical-shaped portion (11) thereof and is engageable with the inner peripheral surface of the pipe member (P). The holder (2) includes a spiral-shaped projection (23) which is formed on the inner peripheral surface (22) of a cylindrical-shaped portion (21) thereof and fittingly engageable with the outer periphery spiral-shaped portion of the pipe member (P). The waterproof packing member (3) is disposed between the wall member (W) and the holder (2).

摘要： A pipe having a substantially square cross section portion and a substantially circular cross section portion are disposed alternately in the axial direction of the pipe. The thickness of the circular portion is set uneven in the circumferential direction. In particular, the thickness of the portions of the circular portion that correspond to the corner portions of the square portion is set larger than the thickness of the portions that correspond to the central portions of the respective sides of the square portions. Accordingly, a pipe having corner portions with increased pressure deformation resistance is obtained. Also, the pipe is capable of being manufactured in a high efficiency manner.
摘要翻译：具有大致正方形截面部分和大致圆形横截面部分的管道沿管道的轴向方向交替设置。圆形部分的厚度在圆周方向上设定为不均匀。特别地，圆形部分对应于方形部分的角部的部分的厚度被设定为大于与正方形部分的各个侧面的中心部分对应的部分的厚度。因此，获得具有增加的耐压变形阻力的角部的管。此外，管能够以高效率的方式制造。

摘要： A joint (and method) connects synthetic resin corrugated pipes, each of the corrugated pipes including a pipe wall having sectionally rectangular wall portions and sectionally circular wall portions disposed alternately in a longitudinal direction of the corrugated pipe. The sectionally circular wall portions each include an annular-shaped protrusion projecting outwardly from the sectionally circular wall portions disposed substantially at a center of the sectionally circular wall portion between adjacent sectionally rectangular wall portions in the longitudinal direction. The joint includes a pair of semicircular-shaped joint main bodies coupled with each other by bolts, each having a recessed groove defined by both of its side edge portions in a width direction thereof and also having tightening bolt holes respectively formed at both peripheral end portions in a peripheral direction thereof, and a pair of watertight packings respectively formed of elastic material and respectively received in the recessed grooves of the semicircular-shaped joint main bodies, each of the watertight packings having a semicircular portion which includes two edge portions disposed at two end portions in a width direction thereof, and a projecting portion disposed between the two edge portions in the width direction and inwardly projected in a radial direction of the pipe.
摘要翻译：接合（和方法）连接合成树脂波纹管，每个波纹管包括管壁，其具有沿波纹管的纵向方向交替布置的截面矩形壁部分和截面圆形壁部分。截面圆形壁部分每个都包括一个环形突起，该圆形突起从基本上位于相邻截面矩形壁部分之间的截面圆形壁部分的中心处的截面圆形壁部分沿纵向方向突出。该接头包括一对通过螺栓彼此连接的半圆形接头主体，每一个具有由其两个侧边缘部分沿其宽度方向限定的凹槽，并且还具有分别形成在两个外周端部处的紧固螺栓孔并且分别容纳在半圆形接头主体的凹槽中的每一个水密性填料均具有半圆形部分，该半圆形部分包括设置在两个第二部分的两个边缘部分在宽度方向上的端部，以及设置在两个边缘部分之间的沿宽度方向并沿管的径向向内突出的突出部分。

摘要： A corrugated synthetic resin pipe comprises a pipe wall including sectionally rectangular wall portions and sectionally circular wall portions disposed alternately in a longitudinal direction of the pipe. Each of the sectionally circular wall portions has an annular projected portion disposed at a substantially center of the sectionally circular wall portion between adjacent sectionally rectangular wall portions in the longitudinal direction, to thereby prevent parallel layout or stack layout of pipes from being disturbed.
摘要翻译：波纹合成树脂管包括管壁，该管壁包括沿管的纵向交替设置的截面矩形壁部分和截面圆形壁部分。每个截面圆形壁部分具有环形突出部分，其设置在纵向方向上的相邻截面矩形壁部分之间的截面圆形壁部分的大致中心处，从而防止管道的平行布局或堆叠布局被扰乱。
