Abstract

PURPOSE:To enable a sheathed tube to be fixed to a sleeper of small breadth or a small beam by providing the first fixing section having surface in contact with one external side of an underfloor structural member as integral part of a sheathed tube holding section, and the second fixing section almost orthogonal with the first fixing section and coming in contact with another adjacent external side of the member. CONSTITUTION:A sheathed tube fastening band 1 is formed out of a metal strip integrating a holding section 1a to hold a sheathed tube 5, and the first fixing and second fixing sections 1b and 1c fitted to an underfloor structural member 4. The first fixing section 1b has contact surface 1d in contact with one side 4a of the member 4 having an almost rectangular cross section, and is fastened thereto with a screw 6. The second fixing section 1c is extended almost along a 90 deg. direction from the section 1b, and has contact surface 1e in contact with another side 4b of the member 4 adjacent in a 90 deg. direction. The side 1e is kept in contact with the side 4b, and secured thereto with another screw 6. According to this constitution, breadth for securing a sheathed tube fastener can be made small, and the dimensional degree of freedom for leading the sheathed tube can be enhanced.

And 01c becomes wider, and sheath tube fixing band 01
Could not be fixed to joist 07.

The present invention has been made in view of the above problems of the prior art, and provides a sheath tube fixing tool capable of fixing the sheath tube to an underfloor structural member such as a narrow joist or beam. The purpose is to

[0007]

In order to achieve the above-mentioned object, a sheath tube fixing device of the present invention is provided with a holding portion formed so as to be able to hold a sheath tube, and is integrally provided with this holding portion. A first fixing portion which has a first contact surface that contacts one surface of the outer peripheral surface of the structural member and is formed so as to be fixed to the one surface of the outer peripheral surface; and the first contact surface. A second contact surface, which has an angle of about 90 ° and is in contact with another surface adjacent to one surface of the outer peripheral surface of the structural member, is formed so as to be fixable to the other surface. It consists of a fixed part.

[0008]

[Operation] When installing the sheath tube to the underfloor structural member, first,
With the sheath pipe held by the holding portion of the sheath pipe fixture, the sheath pipe is placed along the underfloor structural member such as a joist or beam, and
-The contact surface of one fixing portion of the second fixing portion is brought into contact with one surface of the underfloor structural member, and the contact surface of the other fixing portion is at an angle of approximately 90 ° to the one surface of the underfloor structural member. It is brought into contact with the adjacent other surface, and in this state, each fixing portion is fixed by a predetermined fixing means such as a screw or a nail. As described above, since only one contact surface is brought into contact with one surface of the underfloor structural member, the dimension for fixing the sheath tube fixing tool in the underfloor structural member can be smaller than the conventional size.

The embodiment of the present invention has been described above with reference to the drawings. However, the specific structure is not limited to this embodiment, and the present invention can be applied even if there is a design change or the like within the scope not departing from the gist of the present invention. Included in the invention. For example, in the embodiment, the sheath tube fixing band 1 formed of a strip-shaped metal is used as the sheath tube fixing tool.
However, the present invention is not limited to this, and may be applied to a sheath tube fixing tool having a structure such as the sheath tube fixing saddle shown in FIG. 8. It suffices that the fixing portion to be fixed has contact surfaces that can contact two different surfaces of the underfloor structural member at an angle of approximately 90 °. In addition,
In the case of a saddle structure, the first and second contact surfaces are
It is not necessary to arrange at both ends of the holding part as in the embodiment,
Since these two contact surfaces can be arranged close to each other, in the embodiment, the lower end of the holding portion is arranged at substantially the same height as the lower surface of the joist, whereas in this case the lower end of the holding portion is arranged. Can be arranged below the lower surface of the joist, and can be fixed even if the vertical dimension of the joist is smaller than the outer diameter of the sheath tube. Further, in the embodiment, metal is shown as the material of the sheath tube fixing tool, but the material is not limited to this and a synthetic resin may be adopted. Further, in the embodiment, the sheath tube is routed to the joist by the sheath tube fixture, but the present invention is not limited to this, and may be routed along another underfloor structural member such as a beam. Further, in the embodiment, the example in which the holding portion is formed in a substantially U-shape is shown, but any shape such as a substantially C-shape may be used as long as it can hold the sheath tube. By the way, when it is formed in a substantially C shape, the fixing surfaces can be placed close to each other, as in the case of the above-mentioned saddle, and it is possible to fix a sheath tube with an outer diameter larger than the vertical dimension of the joist. Becomes Further, in the embodiment, the fixing surface is formed on the flange, but the fixing surface may be formed on one surface of the block-shaped portion, for example.

[0021]

As described above, in the sheath tube fixing device of the present invention, the first fixing portion having the first abutting surface which abuts on one surface of the outer peripheral surface of the underfloor structural member, And a second fixing portion having a second contact surface that is in contact with the other surface adjacent to the one surface of the underfloor structural member at an angle of approximately 90 ° with the first contact surface. Since the structure is provided, only one abutting surface is brought into contact with one surface of the underfloor structural member, which is the surface along which the sheath tube is routed, and the width dimension for fixing the sheath tube fixing tool in the underfloor structural member. Is smaller than before,
The effect that the dimensional freedom for arranging the sheath tube is improved compared to the conventional case is obtained.
