Description

  The present invention relates to a fixing member fixing method capable of fixing a fixing member to a fixed member at a distance of a length of a cylindrical spacer.

  When the fixed member is a column, the fixing member is a vertical body edge, and the vertical body edge is separated from the column by the thickness of the heat insulating material, the insulating material is interposed between the column and the vertical body edge. A cylindrical spacer having a length of thickness is interposed, a fastening screw is inserted into the through-hole of the cylindrical spacer from the longitudinal body edge side, and the fastening screw is screwed into the column, so that the longitudinal body edge is cylindrical. The spacer is fixed to the pillar at a distance of the length of the spacer (see, for example, Non-Patent Document 1).

As described above, when fixing the vertical trunk edge to the column by the thickness of the heat insulating material, the cylindrical spacer is fixed in advance because the cylindrical spacer is interposed between the column and the vertical trunk edge. It is necessary to arrange between the pillar and the vertical trunk edge.
Therefore, the work of fixing (attaching) the vertical body edge and the heat insulating material is inferior in workability, becomes a complicated work, prolongs the construction period, and increases the construction cost.
In addition, when inserting a retaining screw into the through hole of the cylindrical spacer from the vertical trunk edge side, mark the position of the through hole of the cylindrical spacer on the vertical trunk edge, and then attach the retaining screw to the cylindrical spacer for this mark. Therefore, the work of fixing (attaching) the vertical body edge and the heat insulating material is inferior and complicated, and the construction period is prolonged and the construction cost is increased.

  The present invention has been made in order to solve the above-described disadvantages, and can perform the work of fixing the fixing member to the fixed member with a distance of the length of the cylindrical spacer with good workability and easily. The fixing method of the fixing member which can be performed is provided.

The present invention is as follows.
(1) From a fixed screw member provided with a screw shaft at the center of the tightening seat having a conical surface and a widening surface that expands and contracting, the outer diameter of the tightening seat A cylindrical spacer capable of expanding the screw shaft movably inserted into a through hole having a small inner diameter, and an insertion hole through which the cylindrical spacer can be inserted with an inner diameter smaller than the outer diameter of the fastening seat. A fixing member fixing method for fixing the fixing member to a fixed member using a fixing member provided, wherein the cylindrical spacer is inserted into an insertion hole of the fixing member facing the fixed member. The screw shaft that has been inserted through the through hole and protruded from the cylindrical spacer and the cylindrical spacer and the screw shaft is screwed into the fixed member, thereby penetrating the insertion hole of the fixing member. One end of the cylindrical spacer on the side of the fixed member A part of the clamping seat enters the through hole of the cylindrical spacer while expanding the diameter on the expanding surface of the clamping seat, and the fixing member is sandwiched between one end of the cylindrical spacer and the clamping seat. The fixing member fixing method is characterized in that the fixing member is fixed to the fixed member at a distance of the length of the cylindrical spacer.
(2) From a fastening screw member provided with a screw shaft at the center of the side of the constricted seat having an expanding surface that expands in a conical shape, on the side where the expanding surface contracts, and from the outer diameter of the tightening seat A cylindrical spacer that is capable of expanding the screw shaft so that the screw shaft is movably inserted into a through hole having a smaller inner diameter, and a contracted end of a contracted surface that contracts in the same conical shape as the expanded surface of the clamping seat. And a fixing member having an inner diameter smaller than the outer diameter of the fastening seat and provided with an insertion hole through which the cylindrical spacer can be inserted. In the fixing method, the screw protruding from the cylindrical spacer through the through-hole of the cylindrical spacer from the large-diameter side of the contracted surface into the insertion hole of the fixing member facing the fixed member Inserting the screw shaft into the fixed member by inserting the shaft and the cylindrical spacer. The cylindrical spacer passing through the insertion hole of the fixing member expands the diameter of one end of the cylindrical member on the fixing member by the expansion surface of the clamping seat, and a part of the clamping seat penetrates the cylindrical spacer. Entering into the hole, the fixing member is clamped by one end of the cylindrical spacer and the clamping seat, and the fixing member is fixed to the fixed member at a distance of the length of the cylindrical spacer. This is a fixing method for a fixing member.
(3) In the fixing method of the fixing member according to (1) or (2), the screw shaft is a woodworking screw shaft.
(4) The fixing member fixing method according to (1) or (2), wherein the screw shaft is a tapping screw shaft or a drill screw shaft.

According to the present invention, the screw shaft and the cylindrical spacer that are inserted into the through hole of the cylindrical spacer from the front side (the side opposite to the fixed member) and the cylindrical spacer are inserted into the insertion hole of the fixing member and screwed. By screwing the shaft into the fixed member, the cylindrical spacer that penetrates the insertion hole of the fixing member expands the diameter of one end on the fixing member side with the expansion surface of the tightening seat, and a part of the tightening seat is cylindrical. The fixing member is inserted into the through hole of the cylindrical spacer, and the fixing member is clamped between one end of the cylindrical spacer and the fastening seat, and the fixing member is fixed to the fixed member at a distance of the length of the cylindrical spacer. Can do.
Accordingly, in the operation of fixing the fixing member having a thickness of about 1 mm, for example, to the fixed member with a distance of the length of the cylindrical spacer, the cylindrical spacer is installed and the fixing screw is fixed. Since the fastening operation by the members can be performed simultaneously, the fixing operation of the fixing member can be performed with good workability, and the work can be simplified, the construction period can be shortened, and the construction cost can be greatly reduced.
Also, the screw shaft protruding from the cylindrical spacer through the through hole of the cylindrical spacer and the cylindrical spacer from the large diameter side of the constricted surface into the through hole of the fixing member and the screw shaft to the fixed member By tightening the screw, the cylindrical spacer that penetrates the insertion hole of the fixing member has its one end on the fixing member side enlarged in diameter by the expansion surface of the clamping seat, and a part of the clamping seat is inside the through hole of the cylindrical spacer. The fixing member can be clamped by one end of the cylindrical spacer and the fastening seat, and the fixing member can be fixed to the fixed member at a distance of the length of the cylindrical spacer.
Therefore, in the work of fixing the thick fixing member having a thickness of, for example, 5 mm or more to the fixed member at a distance of the length of the cylindrical spacer, the installation work of the cylindrical spacer and the fixing screw are fixed. Since the fastening operation by the members can be performed simultaneously, the fixing operation of the fixing member can be performed with good workability, and the work can be simplified, the construction period can be shortened, and the construction cost can be greatly reduced.
And since a screw shaft is a screw shaft for woodworking, a fixing member can be fixed to to-be-fixed members, such as a timber, a wood wool material, a laminated board.
Further, since the screw shaft is a tapping screw shaft or a drill screw shaft, the fixing member can be fixed to a fixed member such as a metal plate.
