It is a figure explaining the method of attaching the nut body of b) to a bolt body.

  The long material support 5 is attached to a bolt body B that is already installed in the structure and supports a long material L such as a wiring material or a piping material, from the axial side of the bolt body B. A nut body 1 that can be attached and maintains the attached state by plastic deformation, and a support body 2 that is fixed to a position where the nut body 1 is not plastically deformed and receives a long material L are provided.

  And the support body 2 is provided with the contact part 2b which contact | abuts or adjoins the part of the bolt body B other than the part which attached the nut body 1, and the load of the elongate material L to carry | support is this contact part 2b. It is also configured so that it can be shared.

  The configuration of the nut body 1 and the method of attaching it to the bolt body B will be described in detail with reference to FIG. 2, but as shown in FIGS. 1 (a) and 1 (b), the nut body 1 has a saddle shape with a pipe stop. Then, the inner surface of the saddle is screwed into the outer surface screw of the bolt body B, and the gripping portion 1c corresponding to the saddle-shaped toe portion is sandwiched between the mounting tools and plastically deformed, so that FIG. As shown in Fig. 2), the bolt body is firmly screwed and attached.

  The support body 2 is constituted by bending a bar as a whole, and is fixed to a position where the nut body 1 is not plastically deformed, and is continuously attached in the axial direction of the bolt body B in the attached state. Abutting portion 2b that extends along the wall and shifts by the thickness of the peripheral wall of the nut body 1 so as to approach the bolt body B and abuts against the bolt body B. Is provided in the vertical direction, it is provided with a support portion 2c that extends in the horizontal direction and receives the long material.

  The support body 2 further continues to the support section 2c. In this embodiment, the vertical section 2d rises up to the same axial position as the fixing section 2a in the vertical direction, and the opening that is continuous to the bolt section B and inclined to the bolt body B side. An inclined portion 2e is provided.

  As shown in FIGS. 2 (a) and 2 (b), the nut body 1 is formed on the outer side of the main body portion 1a and the main body portion 1a provided with an engagement protrusion 1b that is screw-engaged with the outer surface screw of the bolt body B. In order to plastically deform the main body portion 1a along the outer surface screw of the bolt body B, the main body portion 1a includes a pair of grip portions 1c gripped by the attachment tool 6, and has a U-shaped saddle shape as a whole. .

  The opening side of the U-shaped saddle of the nut body 1 allows the bolt body B to pass through. The groove provided on the side of the opening portion 1e and the gripping portion 1c that contacts the attachment tool 6 is referred to as a locking groove 1m. .

  As shown in FIGS. 2 (c) and 2 (d), the attachment tool 6 used when attaching the nut body 1 to the bolt body B is generally the same in shape as a tool called a pliers. And a pair of clamping portions 6b that are opened and closed around the rotation shaft 6a, and the clamping portions 6b securely hold the tip of the gripping portion 1c of the nut body 1 from the beginning to the end of the plastic deformation. Specially, it is characterized in that a pair of holding recesses 6c are provided inside the tip.

  When attaching the nut body 1 to the bolt body B with the attaching tool 6, first, as shown in FIG. 2 (c), the opening 1e of the nut body 1 is passed through and the outer surface of the bolt body B is passed. The screw is engaged with the engaging protrusion 1b of the nut body 1 so that the pair of gripping portions 1c of the nut body 1 in this state is from the side facing the nut body 1 with the bolt body B as the center. The mounting tool 6 is inserted into the pair of holding recesses 6c.

  When the clamping part 6b of the attachment tool 6 is tightened from this state so as to be closed, the holding engagement state between the holding recess 6c and the tip of the gripping part 1c provided with the locking groove 1m is maintained. In this state, the nut body 1 is plastically deformed and the state shown in FIG. 2D is obtained, and the nut body 1 is attached to the bolt body B satisfactorily.

  The nut body 1 is made of steel, and is plastically deformed well in its plastic region to maintain the state after the deformation, and the attached state is maintained well.

  Thus, according to the long material support 5 in which such a nut body 1 and the support body 2 are combined, the support body 2 (that is, the entire support tool 5) is screwed into several screws due to plastic deformation of the nut body 1. Since it is firmly and securely attached to the bolt body B by the engagement, a good attached state is maintained.

  Further, the nut body 1 and the support body 2 are usually fixed by welding, but the fixing position is an arc portion as shown by an phantom line of a two-dot chain line in FIGS. 2 (c) and 2 (d). That is, since the nut body is in a position where it is not plastically deformed, the support tool 5 is attached to the bolt body B without changing the relative positional relationship between the bolt body B and the support portion 2a of the support body 2 due to plastic deformation. Can be attached.

  The position where the nut body is not plastically deformed is also a portion that is arcuate so as to follow the external thread of the bolt body B from the beginning of the portion provided with the engagement protrusion 1b inside the nut body. .

  Furthermore, since it is such a fixed position, the gripping portion 1c of the nut body 1 is sandwiched and held, and the nut body 1 is plastically deformed by the attachment tool 6 so as not to obstruct the attachment.

  Further, the load of the long material L carried by the support portion 2a of the support body 2 is supported by the attachment portion between the nut body 1 and the bolt body B, and the long material L around the attachment portion is supported. The moment due to the load is configured to be received by the bolt body B via the contact portion 2b, and the force acting on the support body 2 is preferably shared by the attachment portion and the contact portion, so that the bolt Since it is supported by the cooperation with the body B, it can withstand a larger load.

  That is, the long material support 5 can support a long material firmly with a simple structure by such a structure.

  Fig.3 (a) is a side view which shows the other example of the elongate material support tool of this invention, (b), (c) is AA sectional drawing of (a). Accordingly, the same parts as those already described are denoted by the same reference numerals and redundant description is omitted. Moreover, in order to avoid complexity, there are cases where all symbols are not repeated.

  The long material support 5A shown in FIG. 3A is longer than the long material support 5 shown in FIG. 1 in the attached state to the bolt body B as shown in FIG. In a state where no load is received, the contact portion 2 b ′ is not in contact with the bolt body B but is in a close state.

  That is, the shift amount in the direction of the bolt body B from the fixing portion 2a to the contact portion 2b ′ is smaller.

  The contact part 2b 'of the present invention includes such a thing and exhibits the same effect as the contact part 2b that contacts the bolt body B. This is because when the load of the long material is received, the lower contact portion 2b ′ from the fixing portion 2a receives the measurement due to the load, bends to the bolt body B side, and contacts the bolt body B.

  Therefore, the long material support 5A provided with such a contact portion 2b 'also exhibits the same effect as the long material support 5 of FIG.

  Also, the long material support 5 of FIG. 1 and the long material support 5A of FIG. 2A also have a circular cross-sectional shape as shown in FIG. 2B. Alternatively, this cross section may be a rectangle as shown in FIG.

  Since the long material supports 5 and 5A of the present invention are formed by bending such a bar having a circular cross section and a rectangular cross section, they can be easily manufactured and the manufacturing cost can be reduced. it can.

  FIG. 4 shows another example of the long material support of the present invention, in which (a) is a front view and (b) is a side view.

  Compared to the long material support 5 of FIG. 1, the long material support 5 </ b> B has the contact portion 2 f between the support 2 </ b> B and the bolt body B attached to the bolt body B, and It is different in that it is configured as a hook portion 2f that surrounds it so that it can be engaged or cannot be easily detached, and the fixing manner of the fixing portion 2a 'of the support body 2B to the nut body 1 is different.

  The end portion of the support 2B, which is a bar, is in contact with the outer surface of the main body portion 1a of the nut body 1 and extends horizontally from here, and is separated from the bolt body B by a predetermined distance. At the position, it becomes a lower portion 2h extending downward along the axial direction of the bolt body B, hereinafter, a support portion 2c and a vertical portion 2d, and the tip thereof is an inclined portion 2g connected to the hook portion 2f. ing.

  As shown in FIG. 4A, the hook portion 2f surrounds the bolt body B, and the hook portion 2f is applied to the bolt body B by the force LF1 caused by the load LF of the long material acting on the support portion 2c. It can be pressed.

  On the other hand, a pressing force of a force LF2 caused by the load LF of the long material acting on the support portion 2c acts on the fixing portion 2a ', and the nut body 1 is pressed against the bolt body B.

  The long material support 5B having such a configuration exhibits the same effect as that of the long material support 5 of FIG. 1 and is also supported by the force due to the load LF of the long material acting on the support portion 2c. Since the action point is pressed against the bolt body B at any action point (hook part 2f, fixing part 2a ') of the body 2B and the nut body 1, the long material support 5B and the bolt body B are actuated. The support relationship by the abutting and holding is further strengthened, and the load bearing strength is increased.

  In particular, in the fixing portion 2a ′, the pressing force of the force LF2 acts on the position where the nut body 1 is not plastically deformed. This restores the state after the plastic deformation of the nut body 1 (opens the gripping portion 1c). In other words, the screw engagement between the engagement protrusion 1b of the nut body 1 and the outer surface screw of the bolt body B is made stronger, and acts on the side that holds the attachment state by plastic deformation more firmly. So convenient.

  In Example 2, the fixing portion 2a 'and the lower portion 2h are fixed to the fixing portion 2a and the abutting portion 2b of the long material support 5 in FIG. 1, and the long material support 5A in FIG. 3A. The fixing portion 2a and the contact portion 2b 'may be used.

  FIG. 5 shows another example of the long material support of the present invention, in which (a) is a front view and (b) is a side view.

  Compared with the long material support 5B of FIG. 4, this long material support 5C has the same hook portion 2f and fixing portion 2a 'of the support 2C, but the support portion 2c continues from the fixing portion 2a' as it is. In this case, the support portion 2c and the hook portion 2f are connected to each other by an inclined portion 2i.

  Even in such a configuration, the long material support 5C is similar to the long material support 5B of FIG. 4 in that forces LF3 and LF4 due to the load LF of the long material acting on the support portion 2c. As shown in the figure, it acts on the hook portion 2f and the fixing portion 2a 'to exhibit the same effect.

  FIG. 6 shows another example of the long material support of the present invention, in which (a) is a front view and (b) is a side view.

  The long material support 5D is similar to the long material support 5B and 5C of FIGS. 4 and 5 in the shape of the hook portion 2f ′ of the support 2D, but the fixing portion 2j is from below the nut body 1. The hook portion 2f 'is continuous to the upper portion, and the support portion 2c is extended horizontally so as to be continuous with the hook portion 2f'. 2d 'is different.

  Even in such a configuration, the long material support 5D acts on the support portion 2c as shown in FIG. 6B, similarly to the long material support 5B and 5C of FIGS. The forces LF5 and LF6 due to the moment of the load LF of the long material acting on the hook portion 2f ′ and the fixing portion 2j exhibit the same effect.

  In this case, since the upper portion of the support portion 2c is opened, it is easy to place and remove the long material L on the support portion 2c.

  FIG. 7 shows another example of the long material support of the present invention, where (a) is a front view and (b) is a side view.

  Compared to the long material support 5B of FIG. 4, the long material support 5E has the same shape and function as the hook portion 2f constituting the support 2E. There is an extended lower portion 2k that extends downward without contacting with the body B, followed by a fixed portion 2m to be fixed to the nut body 1 and a lower portion 2n continuously in a straight line. The support part 2c and the vertical part 2d are provided continuously.

  In addition, a part of the lower part 2k of the support 2E is a locking contact portion 2g that is in contact with the bolt body B with the bolt body B sandwiched at a position on the opening side of the hook portion 2f. Features.

  Even in such a configuration, the long material support 5E is similar to the long material support 5B of FIG. 4 as shown in FIG. 7B, and is a long material that acts on the support portion 2c. The forces LF7 and LF8 resulting from the load LF act on the hook portion 2f and the fixing portion 2m, and the same effect is exhibited.

  In this case, since the upper portion of the support portion 2c is opened, it is easy to place and remove the long material L on the support portion 2c.

  Further, in the long material support 5E, the locking contact portion 2g that is located in the axial direction of the bolt body B with respect to the hook portion 2f and sandwiches the bolt body B in cooperation with the hook portion 2f is provided. Since the long material support 5E is slightly inclined, the locking contact portion 2g does not get in the way when the hook 2f is locked to the bolt body B.

  On the other hand, after the locking of the hook 2f and the bolt body B is completed, when the long material support 5E comes along the axial direction of the bolt body B, the locking contact is made on the opening side of the hook 2f. Even if the contact portion 2g comes into contact with the bolt body B and there is a slight gap between the hook body 2f and the bolt body B, the engagement between the support 5E and the bolt body B at the hook portion 2f in the use posture is further improved. The backlash can be reduced, and the effect of satisfactorily maintaining the engagement state of the long material support 5E and the bolt body B in the normal posture is exhibited.
