INNER FACE MATERIAL PRESSING DEVICE
To provide an inner face material pressing device capable of stably achieving reaction force in pressing an inner face material, efficiently and surely exerting a work to engage the inner face material with an inner face material fixing member disposed on an inner peripheral face of a pipe in safety while moving in a pipe axial direction without necessarily making a worker enter the pipe, and being applied to a pipe of a small diameter (nominal diameter:800-1000 mm or less).SOLUTION: An inner face material pressing device includes a first contact portion 11, a second contact portion 12 and a third contact portion 13 kept into contact with a surface of an inner face material 5, and a strut portion 15 supporting the contact portions 11, 12, 13, the first contact portion 11, and the second contact portion 12 and the third contact portion 13 are respectively positioned on a line at one side on which a face including a pipe axis and a pipe periphery are intersected, and a line at the other side, and the first contact portion 11, and the second contact portion 12 and/or the third contact portion 13 press the inner face material 5.SELECTED DRAWING: Figure 8
【課題】内面材を押圧する際に安定して反力をとることができ、管軸方向に移動しながら管の内周面に設置された内面材固定部材に内面材を係合する作業を、必ずしも作業者が管内に入ることなく、効率よく、安全に、かつ、確実性を以て行うことができ、かつ、小径（呼び径：８００〜１０００ｍｍ以下）の管にも適用できる内面材押圧装置を提供すること。【解決手段】内面材５の表面に当接する、第１の当接部１１と、第２の当接部１２と、第３の当接部１３と、各当接部１１，１２，１３を支持する支柱部１５とを具備し、第１の当接部１１と、第２の当接部１２及び第３の当接部１３とは、管軸を含む面と管周とが交わる一方の線上と、他方の線上とにそれぞれ位置するように配置され、第１の当接部１１と、第２の当接部１２及び／又は第３の当接部１３とが内面材５を押圧するようにする。【選択図】図８
