Description

  The present invention relates to a connecting member of a cable rack used for wiring a cable.

  Conventionally, cable racks are used to route cables. The cable rack is formed by laying a child girder at a predetermined interval between a pair of opposed parent girder, and is arranged under the ceiling by a hanging tool attached to the ceiling surface, for example. Then, the cable is placed on the child beam of the cable rack and wiring is performed.

  In such a cable rack, a plurality of cable racks are connected in the longitudinal direction and arranged below the ceiling. The connection bodies are fixed to the connection ends of both cable racks to be connected, and the connection bodies are bolted to each other. And what is connected with a nut was considered (for example, refer to patent documents 1).

  This connecting member is composed of a connecting body and a connecting bolt and nut, and the connecting body is a fixing portion whose one end is fixed to the connecting end of one cable rack with a fixing bolt and nut. The other end portion becomes an overlapping portion protruding from the connection end portion, and a fixing portion is attached to each of the cable racks to be connected. Then, the overlapping parts of the connection bodies attached to the connection ends of both cable racks are overlapped with each other at an arbitrary angle, and the fastening part composed of the hole formed in the overlapped part is fastened and fixed with the bolts and nuts for connection. Consolidation is complete.

  However, in this case, there is a problem that the angle of both the connecting bodies is easily shifted because both connecting bodies are rotatably connected by connecting bolts and nuts. Therefore, in order to solve this point, when connecting adjacent cable racks so as to make a predetermined angle, the connecting ends of the cable racks are connected to joint members formed so that both end portions make the predetermined angle. The thing which fixed each part was considered (for example, refer patent document 2).

However, in such a connection member of the cable rack, only one angle can be handled by one connection member, and the above-mentioned various types can be dealt with when both cable racks have various angles. It is necessary to prepare dozens of types of connecting members with various angles formed by both ends according to the angle, which is not preferable in terms of design / manufacturing cost and component management, and is also a cable rack connecting member. Since these are integrally formed, even a slight construction error or construction error cannot be flexibly absorbed by one connection member, and the prepared connection member may not be used.

Are overlapped so that the overlapping portion 12 on which the angle fixing means 5 is provided is positioned outside. By adopting such a configuration, it is possible to prevent a plurality of angle fixing means 6 from appearing on the outside and losing the aesthetic appearance.

  In the present invention, it is easy to determine the angle of both connecting members in the case where both connecting members are rotatably connected by connecting bolts and nuts.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. First, the cable rack 4 will be described. As shown in FIG. 2, the cable rack 4 is mainly composed of a pair of parent beams 41 and a plurality of child beams 42 installed between the parent beams 41.

  The main girder 41 is made of a normal metal and is arranged substantially in parallel so as to face both side end portions of the cable rack 4, that is, both end portions in the width (short side) direction. The upper horizontal piece and the lower horizontal piece protrude from the upper and lower end portions to the other parent girder 41 that forms a pair. A plurality of child beams 42 are installed between the pair of parent beams 41. The sub-girder 42 is usually made of metal formed by bending a plate-like member to have a cross-sectional shape, a U-shape, a U-shape with a lip, etc., and the shape is not particularly limited. In the form, it is formed in a U-shape with a lip that opens upward, and this child girder 42 has its both ends fixed to the side vertical pieces of the parent girder 41 by welding or the like.

  Thus, the cable rack 4 which comprises a main body is arrange | positioned under a ceiling in the field via the hanging tool etc. which were attached to the ceiling surface. And the connection to the longitudinal direction of the cable rack 4 is performed by abutting the end portions in the longitudinal direction and fixing the connecting member to the outer surface across the both end portions. The case where it connects so that a direction may not become a straight line is demonstrated.

  As shown in FIG. 1, the connection body 1 is made of a metal having a substantially plate shape. One end of the connection body 1 is a fixing portion 11 fixed to the connection end of the cable rack 4, and the other end is the connection. The overlapping portion 12 protrudes from the end portion and is superposed on the connection body 1 fixed to the other cable rack 4. The fixing part 11 has a substantially U-shaped cross section in which the upper piece and the lower piece protrude from the upper and lower end portions of the vertical piece portion as the main body, and the vertical piece portion, the upper piece, and the lower piece are respectively on the side of the parent beam 41. It is fitted and attached along the outer surface of the vertical piece, the upper horizontal piece, and the lower horizontal piece. As shown in FIG. 2, a fixing tool insertion hole 13 and a fixing tool insertion hole 43 communicating with the overlapping portion of the vertical piece portion of the fixing portion 11 and the side vertical piece of the main beam 41 are formed, and a bolt 91 and a nut are formed. The connecting member 1 is fixed to the main beam 41 by inserting and fastening the fixing device made of 92 into the fixing device insertion holes 13 and 43, and the connection between the parent beam 41 and the connecting member 1 is achieved.

  The overlapping portion 12 of the connection body 1 is a plate-like one extending from the vertical piece portion of the fixing portion 11 and in the present embodiment, the protruding end side edge 12a is formed in an arc shape. The corners are prevented from protruding. An insertion hole 14 is formed in the center portion of the fixed portion 11 (in this embodiment, the center portion of the end edge 12a formed in the arc shape). This insertion hole 14 is for inserting a shaft portion 22 of a bolt 2 of a fastener composed of a metal coupling bolt 2 and a nut 3 that fix the connection bodies 1 fixed to both cable racks 4. The insertion hole 14 of the connection body 1 on the side to which the head 21 of the connecting bolt 2 is fastened is a non-circular hole 14a described later. And this insertion hole 14 and its peripheral part serve as a fastening part to which the bolt 2 and nut 3 for connection are fastened.

  And in this invention, the angle fixing means 5 and the angle to-be-fixed means 6 are provided in both the connected bodies 1, respectively, and the angle which both the connected bodies 1 make can be maintained easily.

  Among the pair of connection bodies 1 that are connection members of the cable rack, at least one angle fixing means 5 is provided separately from the fastening portion in the overlapping portion 12 of one connection body 1 and the overlapping portion 12 of the other connection body 1. In addition, a plurality of angle-fixed means 6 are provided separately from the fastening portion for selectively combining the angle-fixing means 5 and connecting the connecting members 1 at a predetermined angle. In the present embodiment, one through hole 51 as the angle fixing means 5 is formed in the overlapping portion 12 of one connection body 1 at a predetermined interval from the insertion hole 14 to the fixing portion 11 side, and the other connection body 1 is formed. A plurality of (9 in the figure) through-holes 61 are provided as angle-fixed means 6 on the same circumference whose radius is the length from the insertion hole 14 to the through-hole 51 with the insertion hole 14 as the center. They are formed at equal intervals (that is, the central angles are equal). In particular, the central angle is generally set to an angle that is frequently used, for example, 0 °, 30 °, 45 °, 60 °, 90 °, −30 °, −45 °, −60 °, −90 °, and the like. Well, when these angles are used, there is no need to cause an angle shift. If an angle other than these angles is used, as will be described later, it can be handled by not using the bolt 7 and the nut 8 for fixing the angle. Here, although the through hole 51 as the angle fixing means 5 formed in one connection body 1 is formed in a substantially square shape, this will be described later. The through holes 51 and 61 serving as the angle fixing means 5 and the angle fixed means 6 are fastened by the angle fixing bolt 7 and the nut 8 in a communicating state.

  The attachment of the connecting member of the cable rack composed of both the connecting bodies 1 will be described. First, the fixing portion 11 of any one of the connecting bodies 1 is connected to the connection end portion of the cable rack 4. At this time, the connection bodies 1 are connected to each other in advance by temporarily fastening the fastening portions with the connecting bolts 2 and nuts 3, or the fixed portions 11 of one connection body 1 are connected to the cable rack 4. Then, the other connecting body 1 is temporarily fastened with a connecting bolt 2 and a nut 3 so as to be rotatable. Then, the angle formed by both connecting bodies 1 is adjusted to the same angle in accordance with the angle formed by both cable racks 4 to be connected. The through hole 51 as the angle fixing means 5 of one connection body 1 is communicated with one of the plurality of through holes 61 as the angle fixed means 6 of the other connection body 1. Thus, the communicating through holes 51 and 61 are temporarily tightened with bolts 7 and nuts 8 for fixing the angle. Thereafter, the fixing portion 11 of the connection body 1 on the side not connected to the cable rack 4 is fastened and fixed to the connection end portion of the other cable rack 4 with bolts 91 and nuts 92, and finally the connecting bolts 2 and nuts are connected. 3 and the angle fixing bolt 7 and nut 8 are fastened (finally tightened) and fixed.

Here, the fastening by the connecting bolt 2 and the nut 3 will be described. The connecting bolt 2 is connected by inserting the shaft portion 22 into the insertion hole 14 in which the overlapping portions 12 of both connecting bodies 1 are overlapped and communicating with each other, and screwing the connecting nut 3 to the shaft portion 22. The overlapping portion 12 of the body 1 is fixed, but the insertion hole 14 formed in the connection body 1 has a shortest distance between the inner end edges so that the shaft portion 22 of the connecting bolt 2 is inserted. It is formed to have a length substantially the same as the diameter of the shaft 22 or slightly longer than the diameter of the shaft portion 22. The insertion hole 14 of the connecting body 1 on the side where the connecting nut 3 is fastened is formed in a substantially circular shape similar to the cross section of the shaft portion 22, and the head of the connecting bolt 2. The insertion hole 14 of the connection body 1 on the side to which 21 is fastened is a non-circular non-circular hole 14a (in this embodiment, a square shape, but not particularly limited to a polygon or the like), and the connecting bolt 2 A non-circular portion 23 is formed in the base portion of the shaft portion 22 and has substantially the same shape as the non-circular hole 14a and is fitted into the non-circular hole 14a. Accordingly, when the connecting bolt 2 is inserted into the insertion hole 14 (non-circular hole 14a) of the connecting body 1 and fastened with the connecting nut 3, the connecting bolt 2 is prevented from rotating. be able to. At this time, the thickness t ₁ of the non-circular portion 23 (that is, the length in the longitudinal direction of the shaft portion 22) is adjusted so that the back surface of the head portion 21 of the connecting bolt 2 contacts the outer surface of the connection body 1. ) Is formed to be thinner than the thickness t _{2 of} the portion of the connecting body 1 where the non-circular hole 14a is provided, and the projecting end surface of the non-circular portion 23 abuts against the outer surface of the other connecting body 1 This prevents the second head 21 from floating.

  When the non-circular portion 23 of the connecting bolt 2 does not fit in the non-circular hole 14a of the connecting body 1 and protrudes toward the other connecting body 1, the non-circular portion 23 is inserted into the insertion hole 14 of the other connecting body 1. If it is not accommodated, the head 21 of the connecting bolt 2 is in a floating state. Therefore, it is necessary to enlarge the insertion hole 14 of the other connecting body 1 to accommodate the non-circular portion 23. This is not preferable because the fastening area between the connecting nut 3 and the other connecting body 1 is reduced and the electrical continuity is reduced. In this respect, the present application is preferable because the non-circular portion 23 is accommodated in the non-circular hole 14a as described above.

  Next, fastening by the angle fixing bolt 7 and nut 8 will be described. The through hole 51 as the angle fixing means 5 formed in one connection body 1 is formed in a substantially square shape having sides that are the same as or slightly longer than the diameter of the shaft portion of the angle fixing bolt 7 described later. Further, the plurality of through holes 61 as the angle fixing means 6 formed in the other connecting body 1 are substantially circular with a diameter that is the same as or slightly longer than the diameter of the shaft portion of the angle fixing bolt 7. Is formed. The bolt 7 for fixing the angle is formed with a square part fitted in the through hole 51 in the same shape as the through hole 51 as the angle fixing means 5 at the base part of the shaft part. The fastening by the angle fixing bolt 7 and the nut 8 is also inserted into the through holes 51 and 61 of the connecting body 1 in the same manner as the fastening by the coupling bolt 2 and the nut 3 described above. Thus, when the angle fixing nut 8 is fastened, the rotation of the angle fixing bolt 7 with respect to the connection body 1 can be prevented.

  Moreover, since both the connection bodies 1 are fastened and fixed by the bolts 2 and nuts 3 for connection, even if a slight construction error or construction error can be absorbed, it can be flexibly dealt with. . For example, by forming the through holes 51 and 61 larger in diameter than the diameter of the shaft portion of the bolt 7 for fixing the angle, “play” is formed, and both can be performed by the angle fixing means 5 and the angle fixed means 6. The angle formed by the connecting body 1 can be widened and the error can be absorbed. In the case of an error that cannot be absorbed even by the “play”, the angle fixing bolt 7 and the nut 8 are not used, that is, the angle fixing means 5 and the angle fixed means 6 are not functioned. Although the angle cannot be maintained in the temporarily fixed state, the cable rack 4 can be connected at an arbitrary angle.

  The order of fixing the connection body 1 to the cable rack 4 is not limited to the order described above, and after fixing one connection body 1 to one cable rack 4, the other connection body 1 is connected to the connection body. 1 is connected to the other cable rack 4 after the other connection body 1 is fixed to the two cable racks 4. After connecting the connection bodies 1 or fixing the connection bodies 1 at a predetermined angle, the connection bodies 1 may be fixed to the cable rack 4.

  In the connection member of the cable rack as described above, both connecting members 1 are connected by fastening the fastening portions with connecting bolts 2 and nuts 3. By providing the angle fixing means 5 and the plurality of angle fixed means 6 respectively, it is easy to determine the angles of both the connecting bodies 1. Even in the state where the connecting bolt 2 and the nut 3 are temporarily tightened to temporarily fix the connecting bodies 1, the angle fixing means 5 and any one of the angle fixed means 6 are attached to the angle fixing bolt 7 and the nut 8. It is possible to maintain the angle formed by both connecting bodies 1 by screwing. In addition, this makes it possible to deal with various angles made by the connecting members 1 with a single cable rack connecting member, which improves workability and eliminates waste from parts ordering to construction. Can be done.

  In addition, the angle fixing means 5 and the angle fixed means 6 are formed by the through holes 51 and 61 as described above, and the angle fixing bolt 7 and the nut 8 are fastened through the through holes 51 and 61. Thus, the angle fixing means 5 and the angle fixed means 6 can be formed simply by drilling the through holes 51 and 61. In this embodiment, only the through hole 51 is provided as the angle fixing means 5, but a plurality of the angle fixing means 5 may be provided so as to correspond to the through holes 61 of the angle fixed means 6. Is.

  In the present embodiment, as shown in FIG. 2, the overlapping portion 12 having only the through hole 51 as the angle fixing means 5 is the overlapping portion 12 having the plurality of through holes 61 as the angle fixed means 6. It is superimposed so that it is located outside. By doing in this way, only the through hole 51 as the angle fixing means 5 is located in the portion facing the outside, and the plurality of through holes 61 as the angle fixed means 6 are located outside. This prevents the appearance from being lost.

  Further, the coupling bolt 2 and the nut 3 of the present embodiment are provided with a projection 20 and a projection 30 that bite into the outer surface of the connection body 1 on the contact surface to the connection body 1, respectively. The connecting bolt 2 is provided with four protrusions 20 at substantially equal intervals on the back surface of the head 21, and the connecting nut 3 has a flange portion that serves as a contact surface to the connection body 1. Four protrusions 30 are provided at 31 at substantially equal intervals. When the overlapping portion 12 of both connecting bodies 1 is fastened and fixed by the connecting bolt 2 and the nut 3, the protrusions provided on the connecting bolt 2 and the nut 3 by the tightening force of the connecting bolt 2 and the nut 3. 20 and 30 bite into the outer surface of the connection body 1, and the protrusions 20 and 30 break the insulating coating on the outer surface of the connection body 1, and the base metal of the connection body 1 and the connecting bolt 2 and nut 3 are electrically connected. Both the connecting bodies 1 and both the cable racks 4 can be conducted.

  Further, the bolt 7 and the nut 8 for fixing the angle are not particularly shown, but the protrusions that bite into the outer surface of the connection body 1 are formed on the contact surface to the connection body 1 similarly to the connection bolt 2 and the nut 3. It may be provided. For example, four protrusions are provided on the back surface of the head of the bolt 7 for fixing the angle substantially evenly, and the contact surface of the nut 8 for fixing the angle to the connecting body 1 is spaced almost evenly. Four protrusions may be provided. Accordingly, when the overlapping portion 12 of both the connecting bodies 1 is fastened and fixed by the bolt 7 and the nut 8 for fixing the angle, the projections of the connecting body 1 are tightened by the tightening force of the bolt 7 and the nut 8 for fixing the angle. It will bite into the outer surface and good conduction will be achieved.

  Next, another embodiment will be described with reference to FIG. In this structure, one of the angle fixing means 5 and the angle fixed means 6 is formed as a protruding portion and the other as a fitted portion, and the protrusion as the angle fixing means 5 provided in the overlapping portion 12 of one connecting body 1. The portion or the fitted portion is selectively fitted with the fitted portion or the protruding portion as the plurality of angle fixing means 6 provided in the overlapping portion 12 of the other connecting body 1. In the present embodiment, one protruding portion 52 is provided as the angle fixing means 5, and nine fitted portions 62 including through holes into which the protruding portions 52 are fitted are formed as the angle fixed means 6. By doing in this way, the angle fixing means 5 and the angle fixed means 6 can be formed only by providing the protrusion part 52 and the fitting part 62, and the angle fixing bolt 7 and the nut 8 are also required. Absent.

  The fitted portion 62 is not limited to a through hole, and may be a recessed portion that is recessed from the surface.

  Next, another embodiment will be described with reference to FIG. Since this embodiment is mostly the same as the embodiment shown in FIG. 5, the same portions are denoted by the same reference numerals, description thereof is omitted, and only different portions are described.

  In this embodiment, the insertion hole 14 of one connection body 1 is a long hole 14b through which the connecting bolt 2 can move, and the angle fixed means 6 is attached to the edge 12a of the overlapping portion 12 of the other connection body 1. As shown, a plurality of notches 63 into which the bolts 7 for fixing the angle can be inserted are formed.

  The long hole 14b has a direction in which the overlapping portions 12 are connected to the fixing portion 11 as a longitudinal direction, and the distance between the inner end edges in the longitudinal direction is longer than the diameter of the shaft portion 22 of the connecting bolt 2 ( In the present embodiment, the distance between the inner end edges in the short direction is substantially the same as or slightly longer than the diameter of the shaft portion 22 of the connecting bolt 2.

  Further, the overlapping portion 12 of the connection body 1 on the side where the angle fixing means 6 is provided has an end edge 12a formed in an arc shape as described above, and this arc is centered on the insertion hole 14, The radius is fixed to the axial center position of the connecting bolt 2 inserted so as to be positioned at the end of the elongated hole 14b of the overlapping portion 12 of the other connecting body 1 on the through hole 51 side, and the angle is fixed to the through hole 51. This is the distance between the axial center position of the bolt 7 for use. Then, a plurality of notches 63 into which the angle fixing bolts 7 can be inserted from the outside are formed in the circumferential direction in the end edge 12a.

  In a state where the connecting bolt 2 is located at the end of the long hole 14 b on the through hole 51 side, the angle fixing bolt 7 inserted into the through hole 51 is superposed on the connection body 1 on the side where the angle fixed means 6 is provided. The angle is fixed by being inserted into one of the plurality of cutouts 63 provided on the edge 12a of the portion 12. In a state where the connecting bolt 2 is located at the end of the long hole 14 b opposite to the through hole 51, the angle fixing bolt 7 inserted into the through hole 51 is connected to the side on which the angle fixed means 6 is provided. It is not inserted into the notch 63 provided at the end edge 12a of one overlapping portion 12, and the angle is not fixed.

  The bolt 7 and the nut 8 for fixing the angle are temporarily tightened, and the bolt 2 and the nut 3 for connection are temporarily tightened so that the connection bolt 2 is located at the end of the long hole 14b opposite to the through hole 51. Since the angle between the connecting members 1 is not fixed, an arbitrary notch 63 is selected, and the connecting bolt 2 inserted into the long hole 14b is connected to the end of the long hole 14b on the through hole 51 side. The connecting body 1 is moved so as to be positioned, and the angle fixing bolt 7 is inserted into the selected notch 63 to fix the angle.
