Reference numeral 51 denotes a heat insulating material as an attachment member, which is made of, for example, foamed polystyrene, and has the same thickness as the length of the cylindrical spacer 21.

Next, an example of attaching (fixing) the fixing member 31 and the heat insulating material 51 to the column 41 will be described.
First, as shown in FIG. 2, the heat insulating material 51 is brought into contact with the outer surface of the column 41.
At this time, if there is a possibility that the heat insulating material 51 may slide down from the outer surface of the column 41, it is desirable to temporarily fix the heat insulating material 51 to the column 41.
Then, as shown in FIG. 2, the fixing member 31 is vertically arranged at the position of the column 41 extending vertically, and the cylindrical spacer is inserted into the insertion hole 32 of the fixing member 31 through the through hole 22 of the cylindrical spacer 21. The screw shaft 13 of the fixed screw member 11 protruding from 21 and the cylindrical spacer 21 are inserted, and the screw shaft 13 is pierced into the heat insulating material 51.

Next, when the screw shaft 13 is screwed into the heat insulating material 51 while pushing the fixing screw member 11, the screw shaft 13 opens the heat insulating material 51 and the tip of the screw shaft 13 abuts on the column 41 as shown in FIG. .

Accordingly, in the operation of fixing the fixing member 31 to the column 41 at a distance of the length of the cylindrical spacer 21, the installation operation of the cylindrical spacer 21 and the fastening operation by the fixing screw member 11 can be performed simultaneously. The fixing work of the fixing member 31 can be performed with good workability, and the work can be simplified, the work period can be shortened, and the construction cost can be greatly reduced.
Since the screw shaft 13 is a woodworking screw shaft, the fixing member 31 can be a fixing tool F suitable for fixing the fixing member 31 to a fixed member made of a wood material such as wood, wood wool, and laminated board.

In the above-described embodiment, the example in which the fixing tool F is configured by the fixing screw member 11, the cylindrical spacer 21, and the fixing member 31 is shown. However, the fixing tool is configured by the fixing screw member and the cylindrical spacer. May be.
Moreover, although the example which made the fixing screw member 11 metal was shown, the non-metallic, for example, plastic fixing screw member may be used.
Moreover, although the example which made the expansion surface 14a of the wedge part 14 conical surface shape was shown, as long as the cylindrical spacer 21 can be diameter-expanded, another shape may be sufficient as a expansion surface.
Moreover, although the example which formed the wedge part 14 in the column shape was shown, the wedge part may be an I-cut shape.
Further, an example of the fixing screw member 11 in which a wedge portion 14 having an expanding surface 14a that expands from the end on the screw shaft 13 side to the tightening seat 12 side is provided between the tightening seat 12 and the screw shaft 13. The screw shaft extends from the center of the clamping seat, and the diameter of the cylindrical surface can be expanded at least at a part of the circumferential surface at a predetermined distance (the thickness of the fixing member) from the clamping seat of the screw shaft. A similar effect can be obtained even with a fixing screw member having a configuration in which a diameter-expanding portion capable of expanding one end of the spacer is provided.
Moreover, although the cylindrical spacer 21 is shown as an example in which the metal plate is rounded into a cylindrical shape and has a slit in the axial direction, the wedge portion 14 can be provided even if the slit is not provided in the axial direction. It may be a cylindrical spacer made of metal or non-metal having a thickness that can be expanded by, for example, plastic.
In addition, although the heat insulating material 51 is interposed between the fixing member 31 and the column 41, the fixing member 31 is fixed to the column 41 with a distance of the length of the cylindrical spacer 21. Even if nothing is interposed between the fixing member 31 and the column 41, another member may be interposed.
When a hard member that cannot be expanded and crushed by the cylindrical spacer 21 is interposed between the fixing member 31 and the column 41, one end of the cylindrical spacer 21 is expanded in diameter to the hard member. The fixing member 31 can be fixed to the column 41 in the same manner as described above by providing a hole that can hold the fixing member 31 between one end of the cylindrical spacer 21 and the fastening seat 12.
Further, the example in which the fixed member is the column 41 has been shown, but the fixed member is a metal plate or the like, and the screw shaft is a tapping screw shaft or a drill screw shaft so that the fixing member 31 is a metal plate or the like. It can be set as a fixture suitable for fixing to a to-be-fixed member.
