Abstract
A void filling device which facilitates insertion of a void filling material into a tubular component and hold of the void filling material therewithin. The device comprises a holder for void filling material which is designed to retain the void filling material to fill a void space by expanding with heat and is of a different material from the void filling material so as to be elastically deformed and inserted into the void space. When the cross-sectional configuration of the void space of the tubular component is a rectangle, the holder is formed into a plate-like configuration which is longer than the diagonal line of the rectangle and is adapted to be insertable into the void space by bending the same arcuately.
Claims6
A void filling device, comprising:
- a void filling material to fill a void space by expanding with heat;
- retaining means for retaining said void filling material;
- elastically deformable means being formed of a different material from that of said void filling material and insertable into the void space by being elastically deformed;
- a cross-sectional configuration of the void space being a rectangle, said void filling device further comprises a plate-like material which is longer than a diagonal line of the rectangle, said plate-like material including said retaining means and said elastically deformable means and being adapted to be insertable into the void space by being bent arcuately;
- and
- said retaining means includes a hole provided in said plate-like material and said void filling material is inserted into the hole.
A void filling device, comprising:
- a void filling material to fill a void space by expanding with heat;
- retaining means for retaining said void filling material;
- elastically deformable means being formed of a different material from that of said void filling material and insertable into the void space by being elastically deformed;
- and
- said retaining means includes a pair of closure plates for retaining the void filling material therebetween, and said elastically deformable means includes an elastically deformable portion for interconnecting said pair of closure plates.
A void filling device, comprising:
- a void filling material to fill a void space by expanding with heat;
