Description

  The present invention relates to an improvement in a support used for supporting piping and other desired arrangements to be arranged on a structure such as a ceiling of a building.

  For example, a deck plate may be stretched on the ceiling of a building. In many cases, a groove is provided in the lower surface of the deck plate, and the groove has an inner width wider than the opening width of the groove opening. Such a groove is often used as a locking portion of a support when a wiring or piping material is disposed, and various support tools for that purpose have been proposed.

   For example, as shown in FIG. 11, in the hanging metal fitting of Patent Document 1, when a bolt is fastened to the nut portion of the hanging metal fitting and the bolt tip is brought into contact with the bottom of the groove, the repulsive force causes the wing portion of the hanging metal fitting to have the groove It is pressed in a state of being almost perpendicular to the side wall and can withstand the load caused by hanging.

   Moreover, in the support tool of patent document 2, it has a shape like a flat head bolt as shown in FIGS. 12-13, and the latching | locking part used as the head latches in a groove | channel. And this is inserted into a groove | channel by dividing | segmenting into two division bodies, and it latches by aligning a division body to the original one.

Moreover, as shown to FIGS. 14-15, the support tool of patent document 3 rotates and attaches the support tool inserted in the groove | channel.

  However, in the hanging metal fitting of Patent Document 1, the bolt must be rotated until the tip of the bolt comes into contact with the bottom of the groove, which is troublesome to mount.

 This also applies to the support of Patent Document 2. If the engaging portion does not match the size and shape of the groove, another support that matches the groove must be prepared.

 Further, the support tool of Patent Document 3 is inserted into the groove and rotated to be attached. However, since this supportable structure allows reverse rotation of the attached support tool, There is a problem such as being pulled out of the groove by being reversely rotated by being pulled by a pipe or the like.

   Moreover, even if the groove of the deck plate is the same standard product, there is a dimensional tolerance in the opening width and the like. On the other hand, the suspension metal fittings of Patent Documents 1 to 3 assume specific dimensions. Depending on the dimensional tolerance of the groove of the attachment destination, the size may not match, and a problem may occur in the installation.

   Therefore, the object of the present invention is that it can be easily mounted on a deck plate or other structure having a groove, can be widely adapted to the dimensional tolerance of the groove, and can be rotated with respect to the groove as the mounting location. An object of the present invention is to provide a support for an arrangement body that does not move in a groove.

For the above purpose, the invention according to claim 1 of the present application is an arrangement body fixed to a building material having an opening and having an inner width wider than the opening width of the opening and having a groove. It is the arrangement | positioning body support tool which supports. And a support body having a fixing portion to which the arrangement body is fixed, the support body having a bent portion where the main body is bent at at least one place, and the bent portion disposed in the groove. And at least a pair of engaging portions that are engaged with the groove by being bent at, and at least a pair of gripped portions that are gripped for the bending.

  The engaging portion is formed on the bent portion side and is disposed on one side wall side of the groove, and is longer than the inner width of the groove from the first engaging portion. And a second engaging portion that is disposed on the other side wall side by bending and separating the main body.

  Furthermore, with the engaging portion disposed in the groove, the second engaging portion is bent at a bent portion so that the second engaging portions are brought close to each other, thereby being engaged with the groove to prevent it from rotating and coming off. It is characterized by that.

   The invention described in claim 2 is characterized in that, in the invention described in claim 1, the bent portion is formed so as to be plastically deformable so as to maintain the bent state.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the engaging portion is provided with a locking portion that bites into and locks the side wall to prevent the groove from moving in the longitudinal direction. It is characterized by.

  The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the engaging portion is fixed to a groove recessed in the lower surface of the deck plate which is a building material, and the fixing portion is disposed. Wiring or piping material which is a body is fixed.

  According to the first aspect of the present invention, when attaching to the groove, the attachment is made only by gripping the gripped portion and bending the support tool body, thereby realizing easy attachment. In addition, even if the groove to be attached is of various sizes, as long as the second engagement portion is separated from the first engagement portion longer than the inward width of the groove, the first engagement portion and the first engagement portion are bent. The two engaging portions are in contact with the respective side walls to mount the support, and as long as the two engaging portions are in contact with the width of the groove. Further, since the first engaging portion and the second engaging portion are in contact with the side wall, the rotation is also prevented.

   According to the second aspect of the invention, since the bent state is maintained by plastic deformation, the engaged state of the engaging portion is also maintained.

   According to invention of Claim 3, since a latching | locking part bites into the side wall of a groove | channel, it is controlled that the support tool after attachment moves to the longitudinal direction of a groove | channel.

   According to the fourth aspect of the present invention, the ceiling deck plate can be used for hanging various arrangement bodies.

  Next, an embodiment of the arrangement body support of the present invention will be described with reference to the drawings. That is, this arrangement body support is a support fixed to a groove formed on the lower surface of a building material as exemplified by a ceiling deck plate, and the groove is larger than the opening width of the opening. An inward width is formed wide, a support is fixed to the groove, and an arrangement body such as wiring and piping is supported by the support.

  1-3 is formed from a plastic stainless steel plate, and the main body 10 of the support made of this stainless steel plate is the main component. The support body 10 has a bent portion 11 that can fold the support body in half, and a pair of left and right half halves 20 formed symmetrically with respect to the bent portion 11 as a boundary. Yes. The pair of half halves 20 are bent so as to form an angle of about 90 °.

 As will be described with reference to FIG. 1 (a), a concave portion 21 is formed on the left and right sides of the half portion 20, and an inverted trapezoidal engagement portion 22 confined by the concave portion 21 is provided on the half portion. Is formed above. The engaging portion 22 having an inverted trapezoidal shape has end portions on both ends of the apex side 23 protruding left and right, and an end portion on the bent portion 11 side forms a first engaging portion 24a. The other end forms the second engagement portion 24b.

 Further, the corner portions of the end portions constituting the first and second engaging portions 24a and 24b serve as locking portions 25 that bite into the side wall 101 of the groove 100 shown in FIG. In particular, the second engaging portion 24b has an end bent outward so that the corner portion of the locking portion 25 can be satisfactorily bitten.

The engaging part 22 has a top 23 that is longer than the inner width W of the groove. As a result, the first engaging part 24a and the second engaging part 24b are also separated longer than the inner width. Has been. Further, the engaging portion 22 is formed to have the same height as the depth of the groove 100 to be fixed or slightly shorter than the depth of the fixing destination. Can be inserted into.
Further, the recess 21 is formed at a position corresponding to the opening 102 of the groove 100 when inserted in this manner, and the shape of the recess 21 is also the edge of the opening 102 as shown in FIG. It is formed in a shape corresponding to the cross-sectional shape.

  The pair of half halves 20 opened at about 90 ° are bent at the ends of the open ends, and the bent portions form a pair of gripped portions 26 to be gripped at the time of bending. Provides a place to do.

  Further, the lower portion of the half portion 22 is formed in a semicircle protruding downward, and a fixing hole 27 concentric with the semicircle is formed, and this is a fixing portion for fixing an arrangement body such as wiring and piping. 28. For example, a string, a hook, or the like is fixed to the fixing hole 27 to help support the arrangement body.

  The half part 20 configured as described above is a middle part between the engaging part 22 and the fixing part 28 and is connected to the other half part 20 via the bent part 11.

  Next, a usage method in the case where this arrangement body support 1A is used for the groove 100 of the deck plate Xa which forms the lower surface of the ceiling X as shown in FIG. 4 will be described.

  This arrangement body support tool 1A has a pair of half halves 20 that are open with respect to the groove 100 in a posture as shown in FIG. Is inserted into the groove from below the groove 100 with the left and right half halves 20 open in the longitudinal direction of the groove as shown in FIG.

  Then, with only the engaging portion 20 inserted into the groove 100, the gripped portion 26 of the arrangement body support tool 1A is sandwiched between pliers and other gripping tools, and as shown in FIG. 90 ° is further bent. When bent, since the top side 23 of the engaging portion 22 is longer than the inner width W of the groove 100, the engaging portion 22 serves the side wall 101 of the groove 100, that is, the first engaging portion 24a is one side wall of the groove. 101 abuts on the side 101, and the second engaging portion 24b abuts on the other side wall 101 side. Therefore, the concave portion 21 formed in the support body 10 is formed in the concave portion 21 having a depth enough to accommodate the opening 102 of the groove 100 when bent.

  When the gripping force is further increased in this state, the locking portions 25 at the ends of the first engaging portion 24a and the second engaging portion 24b bite into the side wall 101. In this way, the gripping operation is terminated, but the arrangement body support tool 1A is formed of a plastic stainless plate, and the bent portion 11 is also plastically deformable. The state is kept as it is and will not open and return to its original state. Thus, the bent state is maintained by the plasticity of the bent portion 11, and the bent state is also maintained by the biting of the engaging portions 25 of the first engaging portion 24a and the second engaging portion 24b.

  If the arrangement body support 1A is fixed in this manner, an arrangement body (not shown) such as wiring or piping may be fixed to the fixing portion 28.

  Although the arrangement body is supported in this way, a tensile force or an external force to be rotated may be applied to the arrangement body support tool 1A by the supported wiring or piping. Even in such a case, the arrangement body support 1 </ b> A does not move in the groove 100 due to the pulling force because the locking portion 25 bites into the side wall of the groove.

  Further, even when an external force for rotation is applied, the engaging portion 22 longer than the inner width W of the groove 100 is engaged like a brace in a state where it is bridged obliquely in the groove 100, and this state is The rotation is restricted. In addition, the two engaging portions 22 that are obliquely bridged as described above regulate both forward and reverse rotations as shown in FIG. The detent is also effective.

  Also, the deck plate differs depending on the location of the arrangement, and the width of the groove may vary, but even in such a case, the length of the top portion 23 of the engaging portion 22 is inward of the groove. If it is longer than the width, the arrangement body support 1A can be fixed to the groove, so that one arrangement body support 1A can cope with grooves of various groove widths, and the application range is widened.

  In addition, the fixed place of the arrangement | positioning body support tool is not restricted to a deck plate, For example, as shown in FIG. 7, you may fix to the C-shaped rail 200 etc. which were attached to the ceiling. This is because the C-shaped rail also has an opening and is provided with a groove 200 having an inner width wider than the opening width of the opening 202.

  The arrangement body support tool 1B of FIG. 8 has an engaging portion formed in a V shape instead of the inverted trapezoidal shape as in the first embodiment. This arrangement body support 1B has the same configuration as that of the first embodiment except for the engaging portion 22.

  Moreover, 1 C of arrangement | positioning body support tools of Example 3 are formed by bending one stainless steel plate in three places centering on the back plate 30, as shown in FIGS. As in the first embodiment, the support body 10 of the arrangement body support 1C is a half part having an engaging portion 22, a gripped portion 26, and a fixing hole 26 on the left and right sides of the rectangular back plate 30. 20 are extended through the left and right bent portions 11 respectively.

The fixing screw hole 41 can be screwed into a bolt 50 with a ring shown in FIG.

   The ring 51 of the bolt 50 with the ring is used to fix the arrangement body such as wiring and piping, but the fixing hole 27 of the half portion 20 is used without using the fixing screw hole 41. It can be fixed and can be selected. However, the fixing hole 27 of the half part 20 may be omitted, and only the fixing screw hole 41 may be provided.

  An arrangement body support 1D of Example 4 shown in FIGS. 11 to 12 is obtained by bending a horizontally long rectangular stainless steel plate 50 by 90 ° at a central bent portion as shown in FIG. Further, before bending, a T-shaped cut 53 is made in the center of the upper side 51 and the lower side 52 of the stainless steel plate 50, and when the bend is bent at 90 degrees at this center, the portion of the cut 53 becomes the first engaging portion. The second engaging portion 24b may be formed at the stage of punching the stainless steel plate 50.

  In this case, the bent half portion 20 becomes the engaging portion 22 as it is, and the fixing portion 28 is formed by the fixing hole 27 provided in the engaging portion 22.

  As shown in FIG. 14, it is assumed that the arrangement body support 1D is fixed to a C-shaped rail 200a. It is gripped by a gripping tool inserted into the groove 200 and fixed to the groove 200. Once fixed, hooks and other members are locked in the fixing holes 27 to fix the wiring and the like.

  As shown in FIGS. 15 to 16, the arrangement body support 1 </ b> E of the fifth embodiment is similar to the third embodiment, in which one stainless steel plate is bent at three locations around the back plate 30. It is formed. In the support body 10 of the arrangement body support 1E, a horizontally long rectangular half 20 extends from the left and right sides of the square back plate 30 via two left and right bent portions 11, respectively. A rectangular bottom plate 40 bent at a right angle to the back plate 30 has a fixing screw hole 41 at the center and extends as a fixing portion 42 below the back plate 30. The fixing screw hole 41 can be screwed into the bolt rod 52 shown in FIG.

  In addition to the usage of fixing the mounting body support tool 1E to the groove of the ceiling, for example, as shown in FIG. 17, the groove 211 of the lightweight steel 210 used for the column of the lightweight partition wall is fixed. It may be used such as. In this case, since the groove 211 is in the vertical direction, the arrangement body support 1E is fixed sideways as shown in FIG. Then, the bolt rod 52 is screwed into the fixing screw hole 41 of the bottom plate 40, and a desired arrangement body can be fixed thereto. For example, a switch box may be attached.
