Description

  The present invention relates to a pipe hanger for suspending piping arranged on a ceiling or the like of a building such as an apartment house.

  Conventionally, pipes for water supply and drainage disposed on the ceiling or the like of a building have been conventionally suspended by a pipe hanger 51 as shown in FIG. The pipe hanger 51 includes a pair of sandwiching portions 52 and 52 that are connected to each other by a hinge 59 to sandwich a pipe (not shown), and suspension portions 53 and 53 that are continuous above the sandwiching portions 52 and 52. The holding body 54 having the above structure, a hanging tool 55 attached to the building, and a bolt 56 and a nut 57 for connecting and fixing the holding bodies 54 and 54 to the hanging tool 55 are provided.

  In such a pipe hanger 51, for example, first, a flanged nut 58 is screwed and fastened to an anchor bolt (not shown) provided on a support member attached to the building, thereby supporting the upper portion of the hanger 55. Secure to the member. Next, the pipes are clamped between the clamping parts 52 and 52, and the bolt 56 and the nut 57 are fastened.

  The conventional pipe hanger 51 as described above requires fastening members such as bolts 56 and nuts 57, has a large number of parts, and has a problem that workability on site is not good. That is, during construction, a tool for fastening the bolt 56 and the nut 57 is always required, and the fastening work is usually performed in a high place or a narrow place where a scaffold is required, so that it is not easy. There were many cases. For this reason, there has been a problem that the total construction cost including the member cost becomes high. Moreover, the bolt 56 and the nut 57 may fall off at the time of construction.

  In addition, in order to prevent the nuts with flanges 58 for attaching the hanger 55 to the building, both side walls on the upper side of the hanger 55 are pressed from both outer sides to form inner protrusions 55a and 55a. However, such processing was very troublesome and time-consuming. Further, since piping is generally installed at a high place, from the viewpoint of safety, the piping is temporarily temporarily placed in one clamping portion 52 until the piping is fixed with the bolt 56 and the nut 57. It is also desirable to be able to hold it in a state.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a pipe hanger that has good workability and can be easily manufactured so that piping can be suspended without using a tool.

A pipe hanger according to the present invention includes a sandwiching body having a pair of sandwiching portions that are pivotally connected to each other at a lower portion so as to sandwich a pipe, and a locked portion that is continuous above the sandwiching portion, and the sandwiching body One locking portion for locking the one locked portion of the holding body in a detachable and non-detachable manner, the other locking portion for locking the other locked portion of the sandwiching body detachably, and A suspension member having a fixing portion that can be fixed to a support member that is connected to the building connected to the upper side of both of the locking portions, and
In order to lock the locked state of the other locked portion, a lock member provided rotatably on the outside of the other locked portion, and a nut hole formed in a fixing portion of the suspension member A drop-off preventing member provided inside the other locking portion to prevent the nut member with the head inserted from falling off is attached to the other locking portion of the suspension member by a fastening member .

  According to such a structure, since the nut member with a head is prevented from falling off by the fall-off preventing member, the construction for attaching the suspension member to the support member of the building can be reliably performed. Then, after one latched portion of the sandwiching body is latched to one latching portion of the suspension member fixed to the building, the pipe is sandwiched between the sandwiching portions, and the other latched body If the engaging portion is engaged with the other engaging portion of the suspension member and the engagement state is locked by the lock member, the pipe can be stably suspended on the pipe hanger without using a tool. In addition, since both the lock member and the drop-off prevention member are attached to the other engaging portion of the suspension member by the fastening member, for example, if a rivet is used for the fastening member, the lock member and the drop-off prevention member can be locked by a simple one-time rivet caulking process. The member and the drop-off preventing member can be easily attached.

  In such a pipe hanger, a drop-off preventing member provided inside the other locking portion may be provided with a temporary fixing portion for temporarily fixing the pipe to one of the holding portions of the holding body. In this way, since the pipe can be held in a stable temporarily fixed state, safety can be ensured even in high-altitude work.

  You may provide the temporary stop part for temporarily fixing the piping mounted in one clamping part of the said clamping body in the lower end of said other latching | locking part. In this case, for example, it may be formed in a chamfered shape in order to extend the lower end of the pipe until it comes into contact with the upper part of the pipe so that the pipe can be inserted.

  Both locking portions may be provided in parallel at a predetermined interval, and the both locked portions may be locked outside the both locking portions.

  A locking piece bent upward is formed on one locking portion of the suspension member, an opening is formed on one locked portion of the holding body, and an upper edge of the opening is the engagement portion. You may make it latch on a stop piece.

  Further, the upper portion of the locking piece bent upward may be formed in an outwardly open shape so as to facilitate locking of the opening formed in the one locked portion to the locking piece. Good.

  Since the pipe hanger according to the present invention prevents the nut member with the head from falling off by the drop-off preventing member, it is possible to reliably perform the construction for attaching the suspension member to the support member of the building. Then, after one latched portion of the sandwiching body is latched to one latching portion of the suspension member fixed to the building, the pipe is sandwiched between the sandwiching portions, and the other latched body If the engaging portion is engaged with the other engaging portion of the suspension member and the engagement state is locked by the lock member, the pipe can be stably suspended on the pipe hanger.

  Therefore, piping can be suspended without requiring a tool, and the workability is remarkably improved. Moreover, since it is not necessary to use a fastening member separately, parts, such as a fastening member, do not drop out during construction work, work can be carried out without delay, and safety during work is improved. And since both a locking member and a fall-off prevention member are attached to the other latching | locking part of a suspension member with a fastening member, manufacture becomes easy.

Below, the pipe hanger which concerns on the best embodiment of this invention is demonstrated in detail, referring drawings.
[Embodiment 1]

As shown in the figure, the pipe hanger 1A basically includes a holding member 4 for holding a pipe (not shown) and a suspension member 7 fixed to a support member (not shown) attached to the building. And.

  The sandwiching body 4 includes a pair of sandwiching portions 21 and 22 and locked portions 31 and 32 that are continuous above the sandwiching portions 21 and 22. The pair of sandwiching portions 21 and 22 are formed in a substantially semicircular arc shape so as to face each other by bending a sheet metal material having a predetermined width, and are connected to each other at a lower end portion by a hinge 13 so as to be relatively rotatable.

  On the other hand, as shown in FIGS. 2A to 2D, the suspension member 7 leaves a flat portion at the center of a sheet metal member having a predetermined width and bends both sides downward to keep a predetermined interval. Then, both side walls 71 and 72 that are suspended in parallel and face each other are formed, and locking portions 51 and 52 for detachably locking the both locked portions 31 and 32 of the sandwiching body 4 are formed below the side walls 71 and 72, respectively. The rivet hole 72a is formed in the upper part of the other side wall 72, and the fixing part 6 having the nut hole 6a is provided in the upper flat part.

  The locking part 51 formed at the lower part of the one side wall 71 has a locking piece 51a that is partly raised and bent upward, and the upper part of the locking piece 51a is slightly open outward. Is formed. The other locking portion 52 has a locking piece 52a that is partially raised and bent in the lateral direction. The locked portions 31 and 32 of the holding body 4 locked to the both locking pieces 51a and 52a have rectangular openings 31a and 32a (see FIG. 1), respectively.

  And the fall prevention part 81 which supports the nut 14 with the flange inserted in the nut hole 6a of the fixing | fixed part 6 from the downward direction, and the piping mounted in one clamping part 21 for supporting in a temporary placement state The drop-off prevention member 8 provided with the temporary fixing portion 82 and the lock member 10 are attached to both the inside and outside of the side wall 72 by rivets (fastening members of the present invention) 12 inserted into the rivet holes 72a of the other side wall 72. ing. The suspension member 7 can be fixed to the building by screwing and fastening the nut 14 to an anchor bolt (not shown) fitted in a support member attached to the ceiling or the like of the building.

  The drop-off prevention member 8 is made of a plate member, and is formed by bending the upper part of the plate member into approximately 90 ° one side as shown in FIGS. 3 (a) to 3 (c), and is screwed into the nut 14. Has a split groove 81a through which the nut 14 is inserted, and is arranged in contact with or close to the lower portion of the nut 14. The temporary fixing portion 82 is formed by folding the lower portion of the plate member upward, and urges and abuts in a line contact state with the pipe P placed on the one holding portion 21 suspended by the suspension member 7. Corresponding to a state that is extremely close to the extent that it can be prevented. A rivet hole 8 a for inserting the rivet 12 inserted through the rivet hole 72 a of the other side wall 72 is formed below the drop-off preventing portion 81.

A lock member 10 that is rotatably supported by the rivet 12 is provided outside the other side wall 72 of the suspension member 7, and the other locked portion 32 is locked to the locking piece 52 a. Can be locked. The lock member 10 has an operation piece 10a, and is locked at a position where the other locked portion 32 is locked by _two dowels d ₁ and d ₂ formed on the outer surface of the other side wall 72 (FIG. 1). A solid line (b) and a lock release position (two-dot chain line in FIG. 1B) can be temporarily fixed. The dowel d ₁ is a flat head dowel that the locked portion 32 cannot get over, and d ₂ is a round head dowel that the locked portion 32 can get over. These dowels d ₁ and d ₂ can be easily formed by pressing.

  In the pipe hanger 1A configured as described above, first, the opening 31a of the one locked portion 31 of the holding body 4 with respect to the one locking piece 51a of the suspension member 7 fixed to the support member of the building. Is fitted from the outside, and the upper edge of the opening 31a is locked to the one locking piece 51a so that it can be engaged and disengaged. In that case, since the upper part of the locking piece 51a is formed in a slightly outward shape, the fitting operation of the one opening 31a to the locking piece 51a becomes easy. At this time, the other clamping part 22 and the locked part 32 are in an open state opened with respect to the one clamping part 21 and the locked part 31.

  Next, when the pipe P is fitted into one of the holding parts 21, the temporary fixing part 82 of the drop-off preventing member 8 comes into contact with the pipe P, and the pipe P is supported by the holding part 21 in a stable temporary placement state. When the pipe P is fitted, for example, a part of the outer periphery of the pipe P is slightly deformed and passes through the temporary fixing part 82 to come into contact with the temporary fixing part 82 in a stable temporary fixing state. And if the opening 32a of the other to-be-latched part 32 of the clamping body 4 is latched by the other latching piece 52a of the suspension member 7, and the latching state is locked by the lock member 10, the piping P will be obtained. The pipe hanger 1A can be suspended in a stable state. In the temporarily fixed state, the outer periphery of the pipe P is not necessarily in contact with the temporary fixed part 82, and the pipe P and the temporary fixed part 82 have a slight gap in a state that is extremely close to each other so that they can be prevented from coming off. You may respond.

  Therefore, it is possible to easily suspend the pipe from the pipe hanger without requiring a tool or skill, and the workability is remarkably improved. Further, since a conventional fastening member is not required separately, the number of parts is reduced, the pipe hanger 1A can be provided at low cost, and the total construction cost including the member cost can be significantly reduced. . In addition, when the piping P is easy to deform | transform, although fitting is accept | permitted by deform | transforming a part of outer periphery at the time of the fitting, the fall prevention member 8 is formed with a thin plate material, and appropriate elasticity is provided. Thus, even if the rigidity of the pipe P is high, the fitting of the pipe P can be permitted by the deformation of the temporary fixing portion 82 of the drop-off prevention member 8.
