Description

  The present invention relates to a hanging bracket used for hanging and fixing a piping pipe to perform piping in a building, and more particularly, relates to a hanging bracket that enables piping work to be easily performed.

  As is well known, when piping such as a water pipe is performed in a building, a method of hanging a piping pipe from a ceiling slab using a hanging bracket may be employed. In a conventional hanging bracket, a pair of holding pieces each having a semicircular shape is connected by a hinge so as to be openable and closable at a position on a vertical line passing through the center of the piping pipe, and the piping pipe is held by the pair of holding pieces. And fix.

  When piping is performed using this hanging bracket, generally, the pair of sandwiching pieces is attached to a tangle that is connected to a suspension bolt attached to a ceiling slab by opening one of the sandwiching pieces to an open state. One of the connecting pieces formed at the upper end of each is supported so as to be hooked via a bolt, and in that state, the piping pipe is supported by one hand so as to be held by one of the holding pieces and then opened. The clamping piece is closed, and the bolt is passed through the connecting piece and tightened with a nut, thereby supporting the piping pipe on the hanging bracket.

However, in piping work using such conventional hanging brackets, the piping pipes are supported manually with respect to the hanging brackets that are suspended in an open state, one clamping piece is closed, and bolts and nuts are used. Since it is necessary to perform screw tightening and it is necessary to support a long and heavy piping pipe manually until the screw tightening of the nut, it is generally indispensable for multiple workers to share the work. The problem of poor workability remains.

Therefore, in order to solve the problem of such a hanging metal fitting, the lengths of the pair of holding pieces are made different, i.e., the holding pieces are displaced in the outer peripheral direction from the perpendicular passing through the center of the piping pipe. There has been proposed a hanging metal fitting that is openably and closably connected, and that the holding piece on the long side is used for temporarily holding the piping pipe and the holding piece on the short side is used for holding and fixing the piping pipe.

JP-A-11-173462

  However, when the length of the pair of clamping pieces is different, the hanging piece with the long side holding piece for temporarily placing the piping pipe and the short side holding piece for holding and fixing the piping pipe In this case, when the piping pipe is supported by the holding piece on the long side, if any impact is applied to the piping pipe, there is a possibility that the piping pipe may fall from the holding piece on the long side. It is done. In such a case, it is possible to point out the problem that the piping pipe must be held again by the long-side clamping piece, resulting in poor working efficiency.

  Then, this invention makes it the subject to provide the hanging metal fitting which makes it possible to perform piping work more efficiently.

The hanging bracket of the present invention is
A hanging bracket having an inner diameter corresponding to the outer diameter of the pipe pipe to be supported, is configured by opening and closing a pair of clamping pieces each having a bolt hole at each upper end portion,

  In the hanging metal fitting of the present invention, the holding piece constituting the hanging metal fitting is constituted by a clamp side holding piece and an upper side holding piece, and the clamp side holding piece has a length dimension that is more than half the inner diameter of the hanging metal fitting. The clamp-side clamping piece can be temporarily placed and supported, and the lower end portion of the clamp-side clamping piece is formed with a claw portion that prevents the piping pipe from being inserted into the clamp-side clamping piece. Yes.

  Therefore, when inserting the piping pipe into the clamping side clamping piece, the piping pipe must be pushed inside the clamping side clamping piece, and after inserting the piping pipe into the clamping side clamping piece, Even when an impact is applied to the piping pipe, the piping work can be performed more efficiently without fear of the piping pipe falling from the clamp-side clamping piece.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a hanging bracket according to the present invention will be described with reference to the drawings. FIGS. 1 and 2 are perspective views of the hanging bracket according to this embodiment, FIG. 1 is in a closed state, and FIG. In the figure, reference numeral 1 denotes a hanging bracket of the present embodiment.

  And the hanging metal fitting 1 of a present Example is metal, and has an internal diameter according to the outer diameter of the piping pipe to support. Moreover, the hanging metal fitting 1 of a present Example comprises a pair of clamping piece, and is comprised by connecting this clamping piece mutually so that opening and closing is possible.

  Here, the clamping piece will be described. In this embodiment, the clamping piece is a clamp-side clamping piece for supporting the piping pipe and an upper-side clamping for fixing the piping pipe supported by the clamping-side clamping piece. It is composed of pieces.

  First, the clamp-side clamping piece 2 will be described. In FIGS. 1 and 2, 2 is the clamp-side clamping piece 2, FIG. 3 is a perspective view of the clamp-side clamping piece 2, and FIG. 4 is the clamp-side clamping piece. 2 is a front view of a piece 2. FIG.

  And the said clamp side clamping piece 2 has the clamp side clamping piece main body 4 made into circular arc shape in the figure, The plate-shaped attachment part 5 is formed in the upper end part of this clamp side clamping piece main body 4, A mounting bolt hole 6 is formed at the upper portion of the mounting portion 5, and a fixing bolt hole 7 is formed below the mounting bolt hole 6. In FIG. 3, 8 is a reinforcing rib. In other words, the clamp-side clamping piece 2 is provided with reinforcing ribs 8 upright across the entire end portions along the longitudinal direction on the outer peripheral side.

  Next, the clamp side clamping piece main body 4 will be described. In FIG. 4, the clamp side clamping piece main body 4 of this embodiment has a length that is at least half the total inner diameter of the hanging metal fitting 1. Specifically, in this embodiment, the length is about 5/8 or less of the inner diameter of the hanging bracket 1. Thus, when performing piping work, the piping pipe can be temporarily placed in the clamp-side clamping piece 2.

  Next, 9 is a nail | claw part in a figure. That is, the clamp side clamping piece 2 in the present embodiment has a claw portion 9 formed at the lower end portion, and the presence of the claw portion 9 prevents the pipe from being inserted into the clamp side clamping piece 2. I am going to do that.

  As shown in FIG. 2, the claw portion 9 has a width dimension narrower than the width of the main body portion 4, and a base portion 10 continuously provided in the arc direction at the lower end of the clamp-side clamping piece 2, When the distal end portion 11 having a predetermined length deformed in the outer peripheral direction is provided at the distal end of the base portion 10 and an attempt is made to insert a pipe pipe into the clamping side clamping piece 2, the base portion 10 of the claw portion 9 is obstructed. Thus, the insertion of the piping pipe into the clamping side clamping piece 2 is inhibited.

  Therefore, when the piping pipe is inserted into the clamp-side clamping piece 2, the piping pipe whose insertion into the clamping-side clamping piece 2 is hindered by the presence of the base 10 is strongly pushed into the clamp-side clamping piece 2. There is a need. Therefore, after the piping pipe is pushed into the clamping side clamping piece 2 by being pushed into the clamping side clamping piece 2, the piping pipe is easily fixed in the clamping side clamping piece 2 due to the presence of the base 10. Therefore, even when an impact is applied to the piping pipe, there is no possibility that the piping pipe falls from the clamp-side clamping piece 2.

  Moreover, the said claw part 9 in a present Example is deformable to the outer peripheral side or an inner peripheral side, and a piping pipe is clamp side clamping piece by changing the said base 10 to an outer peripheral side or an inner peripheral side with pliers etc. It is possible to adjust the degree of inhibiting the insertion into 2. Therefore, if it is desired to make the fixation in the clamp side clamping piece 2 strong and take out more difficult, the base 10 is deformed to the inner peripheral side, while the insertion into the clamp side clamping piece 2 is facilitated. If this is desired, it is possible to cope with this problem by deforming the base 10 to the outer peripheral side.

  Next, the upper side clamping piece 3 will be described with reference to the drawings. FIG. 5 is a perspective view showing the upper side clamping piece 3. In the figure, the upper side clamping piece 3 has an arcuate upper side clamping. It has a piece body 12, and a plate-like attachment portion 13 is formed at the upper end of the upper side clamping piece body 12. The attachment portion 13 is formed with a fixing bolt hole 14 for fixing the upper end portion of the upper side holding piece main body 12 to the clamp side holding piece main body 4. In FIG. 5, reference numeral 15 denotes a reinforcing rib. That is, in the upper side clamping piece 3, reinforcing ribs 15 are provided upright across the entire end portions along the longitudinal direction on the outer peripheral side.

  The upper side clamping piece main body 12 has a remaining length obtained by subtracting the length of the clamp side clamping piece main body 4 from the inner diameter of the hanging metal fitting 1 so that the upper side clamping piece main body 12 and the clamp side The clamping piece main body 4 can cover almost the entire circumference of the piping pipe.

  Next, in the figure, 16 is a shaft portion. That is, the upper-side clamping piece 3 protrudes the shaft portion 16 at both ends in the width direction at the lower end portion, and the shaft portion 16 is formed in the tip portion of the rib 8 in the clamp-side clamping piece 2. (See FIG. 3), the upper side holding piece 3 can be rotated with respect to the clamp side holding piece 2, and the upper side holding piece 3 can be turned to open and close the hanging bracket 1. . When the upper holding piece 3 is rotated to close the hanging bracket 1, the fixing bolt hole 14 formed in the attachment portion 13 in the upper side holding piece 3 is connected to the attachment portion 5 in the clamp side holding piece 2. The fixing bolt hole 7 is formed so as to face the fixing bolt hole 7.

  Further, a claw portion 9 formed on the lower end portion of the clamp side clamping piece 2 when the upper side clamping piece 3 is rotated to close the hanging bracket 1 at the lower end portion of the upper side clamping piece main body 12. An escape hole 17 for entering is formed, and the presence of the escape hole 17 makes it possible to rotate the upper side clamping piece 3 and close the hanging bracket 1.

  Next, the operation of the hanging bracket 1 of the present embodiment configured as described above will be described with reference to FIG. 6. A portion 21 indicated by a dotted line in FIG. It is a tan buckle to which the upper end of the metal fitting 1 is connected. That is, when the piping pipe is supported by the hanging metal fitting 1 of the present embodiment, first, the mounting bolt hole 6 formed in the mounting portion 5 of the clamp side holding piece 2 is used to mount the clamping side by the mounting bolt 23. A buckle 22 is attached to the upper part of the sandwiching piece 2. At the same time, the turnbuckle 22 is connected to a suspension bolt suspended from the ceiling or the like of the building, so that the suspension fitting 1 of the present embodiment is suspended from the ceiling of the building.

  Then, the upper holding piece 3 is rotated to the outer peripheral side to open the hanging bracket 1, and in this state, the pipe 21 to be supported is placed on the opening portion of the clamp side holding piece 2 on the surface along the longitudinal direction. Press. In this state, the claw portion 9 becomes an obstacle, and the pipe 21 cannot be inserted into the clamp-side clamping piece 2. Therefore, the surface of the piping pipe 21 is further strongly pressed against the inside of the clamp-side clamping piece 2. Then, while the piping pipe 21 is deformed flat, the piping pipe 21 gets over the claw portion 9 and is inserted into the clamping side clamping piece 2, whereby the piping pipe 21 is inserted into the clamping side clamping piece 2 due to the presence of the claw portion 9. Fixed to.

  Then, the upper side holding piece 3 is rotated to close the hanging metal fitting 1, and the portion of the pipe 21 fixed in the clamp side holding piece 2 that cannot be covered with the clamp side holding piece 2 is the upper side holding piece. 3, the fixing bolt hole 14 formed in the mounting portion 13 in the upper side clamping piece 3 and the fixing bolt hole 7 formed in the mounting portion 5 in the clamp side clamping piece 2 are opposed to each other by the fixing bolt 24. The mounting portion 13 of the upper side clamping piece 3 is fixed to the mounting portion 5 of the clamp side clamping piece 2.

  And at this time, in the hanging metal fitting 1 of the present embodiment, the piping pipe has a claw portion 9 that prevents the piping pipe from being inserted into the clamp-side clamping piece 2. When inserting into the clamping side clamping piece 2, it is necessary to push the piping pipe strongly into the clamping side clamping piece 2 while inserting the piping pipe into the clamping side clamping piece 2 into the clamping side clamping piece 2 After that, since the piping pipe is fixed in the clamp side clamping piece 2 due to the presence of the claw portion 9 and cannot be easily taken out, the upper side clamping piece 3 is attached to the mounting portion 5 of the clamp side clamping piece 2. Even before the portion 13 is fixed, even if an impact is applied to the piping pipe, there is no possibility that the piping pipe falls from the clamp-side clamping piece 2.

  Moreover, since the said nail | claw part 9 is making it deformable to the outer peripheral side or an inner peripheral side, it can adjust the grade which inhibits that a piping pipe inserts in the clamp side clamping piece 2 by making it deform | transform. Therefore, when it is desired to make the removal in the clamp side holding piece 2 more difficult and to make it difficult to take out, the claw portion 9 is deformed to the inner peripheral side, while the insertion into the clamp side holding piece 2 is performed. In order to make it easy, it is possible to cope with this by deforming the claw portion 9 to the outer peripheral side.

  Thus, in the hanging bracket of the present embodiment, after the piping pipe is inserted into the clamp-side clamping piece, the upper-side clamping piece is rotated so that the piping pipe is fixed in the clamping-side clamping piece. Even if the hanging metal fitting is not closed, even when an impact is applied to the piping pipe, the piping work can be performed more efficiently without fear of the piping pipe falling from the clamp-side clamping piece.

  The suspension bracket of the present invention is a pipe support bracket that supports a pipe pipe with a pair of sandwiching pieces, so that the pipe pipe can be firmly fixed with only one sandwiching piece. Applicable.
