In particular, the present invention relates to hardware for hanging a small-diameter pipe from above and installing the pipe.

[0002]

2. Description of the Related Art Equipment pipes, which are arranged substantially horizontally in a building, are generally constructed in accordance with the Ministry of Construction common specifications. For example, in a gas pipe of 100 A or less, the horizontal support intervals of the pipe are all set to be within 2.0 m.
At a support interval within this regulation, a member having a female screw called an insert which is conventionally installed in the ceiling portion is used, or an anchor is hit, and one bolt is used with one hanging bolt and a hanging hardware. Only tubing. FIG. 10 shows such a conventional hanging hardware, in which one tube 1 is hung by one hanging bolt 2 each. Mounting bracket 3 at the lower end of the suspension bolt 2
And a band portion 4 in which the tube 1 is held
Is attached.

For example, in the case of a gas pipe, the operating weight is 20
A is about 4.5kg, 50A is about 16.0kg, 9
In the case of the specified hanging bolt having a diameter of mm, the pulling strength is 300 kg (one post-anchor anchor). Therefore, the 50A pipe has a strength margin of 18 times and the 20A has a strength margin of 65 times.

[0004] However, since the entire screw bolt and the suspension band with the turn must be used one by one at short support intervals as the suspension hardware, the installation cost is increased, and the above-mentioned strength margin is not effectively utilized. Met.

[0005] Further, the anchoring work to be provided on the lower surface of the ceiling is often performed at a high place on a stepladder or an assembling scaffold, so that there is a high danger as a working condition.

[0006] On the other hand, Japanese Patent Application Laid-Open No. 8-303650 "Apparatus for suspending pipes for air conditioning equipment and pipes for hot and cold water supply" is suitable for discharging a hanging band with a turn and suspending a pair of pipes simultaneously. A pipe suspension device using a bracket has been proposed. According to this technique, up to two pipes can be held by one hanging bolt, and the work of anchoring and attaching to the hanging bolt can be reduced to about half of the conventional one.

[0007]

However, in the apparatus disclosed in Japanese Patent Application Laid-Open No. H8-303650, the bolts of the holding hardware for directly holding the pipe material are temporarily temporarily tightened, temporarily suspended, and then temporarily suspended. The work was not easy and labor was still small, for example, it was necessary to retighten after positioning with a certain bracket, and it was necessary to change tools such as a spanner.

In the above apparatus, a pair of pipes, ie, two pipes,
Although the configuration for holding up to the pipe material is shown, depending on the pipe diameter etc. used, there is still a strength margin in the hanging bolt,
If the number is further suspended, more effective and rational piping can be achieved.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a plurality of pipes suitable for the hanging strength of a hanging member such as a single hanging bolt when a small diameter pipe is hung. An object of the present invention is to provide a hanging hardware that can be held and is easily operated.

Regarding 00-3, the same ones as those of the conventional one-to-one corresponding suspension bolt, mounting hardware 13 and band portion are used.

Although the suspension bolt 100 is shown with an upper part screwed into an anchor female screw, a rod member or the like having a ceiling-side attachment portion to the upper frame and a male thread part at the lower part is suspended. It is also possible to use as a member. In addition, the hanging hardware 10 is formed of a material having a large longitudinal elastic modulus and a high strength, such as an iron material.

FIGS. 2A and 2B are a perspective view and a four-sided view showing a top plate 12 which is a characteristic component of the present invention. In the state where the top plate 12 is attached, a flat portion 12a which forms a substantially horizontal surface portion is provided at the center portion with a structure that allows the flat plate portion 12a to be attached substantially horizontally to the suspension bolt 100. A central hole 21 having a diameter through which the male screw portion of the suspension bolt 100 can be inserted is formed at a substantially central position. The suspension bolt 100 is passed through the central hole 21 and is fixed at a predetermined position using the nut 15 (see FIG. 1).

At the positions near both side ends of the flat plate portion 12a of the top plate 1, suspension band fixing holes 23 for fixing a suspension band for holding a pipe described later are provided one by one on the left and right.

Further, the four sides of the top plate 12 are bent downward, respectively, and the bent portions on the left and right sides in FIG. That is, there are formed elongated band insertion holes 24 in the form of elongated holes slightly larger than the width and thickness of the distal end portion 25 of one arm portion 22 of the suspension band 20 described later. The upper end 24a of the suspension band insertion hole 24 is formed so as to be substantially flush with the lower surface of the flat plate portion 12a.

The front side of the flat plate portion 12a of the top plate 12,
A front plate portion 16 and a rear plate portion 18 which are bent portions are also formed on the back side. The front plate portion 16 and the rear plate portion 18 are formed as reinforcing portions for resisting a bending force applied to the flat plate portion 12a of the top plate 12 when the tube is suspended.

Next, as can be understood from FIG. 1, the suspension band 20 includes two arms 22a and 22b and a hinge 27 for axially fixing the arms 22 so that the arms 22 can be opened and closed. Take the role of holding. As shown in the figure, each arm portion 22 is composed of a belt portion 20a for surrounding the outer periphery and an intermediate auxiliary member 20b disposed inside the belt portion 20a and having a concave portion corresponding to the tube material 300.

Next, with reference to FIGS. 3 and 4, a description will be given of a procedure for suspending a pipe using the suspending hardware 10 according to the above embodiment. The upper portion of the suspension bolt 100 is previously screwed into an anchor female screw hit on the ceiling, and the nut 15-1 is passed through the male screw portion 110. The male screw 110 of the suspension bolt 100 is passed through the central hole 21 of the flat plate portion 12a of the top plate 12,
Further, the nut 15-2 is inserted into the male screw portion 110 from below and manually screwed. Further, it is tightened with a desired torque using a tool such as a monkey spanner.

Thus, the positioning and mounting of the top plate 12 is completed as shown in FIG. In this state, the flat plate portion 12a of the top plate 12 is maintained substantially horizontal with respect to the hanging bolts 100 suspended in this state.

Next, the suspension band 20 is opened,
As shown in FIG. 3B, the end 25 of the one arm 22a is connected to the suspension band insertion hole 24 of the frame 14a of the top plate 12.
Through. The length of insertion is up to a position where the through hole 25a formed in the end portion 25 substantially matches the suspension band fixing hole 23 of the flat plate portion 12a of the top plate 12. In this figure, the other arm connected by a hinge is not shown.

In the above state, the suspension band 20 receives the gravity vertically downward while receiving the tip 25 of the arm 22a.
Is restrained by the lower end 24b of the suspension band insertion hole 24 and the lower surface 12b of the flat plate portion 12a, and a state in which it is not easily dropped is maintained. That is, the lower end 24b of the suspension band insertion hole 24
Is a fulcrum, and the arm portion distal end portion 25, which is an action point, is restricted from moving vertically in the lower surface 12b of the flat plate portion 12a, so that the entire suspension band 20 is supported.

In this way, the frame 14 of the top plate 12 is restrained,
One arm 22 of the suspended band 20 in a supported state
A pipe material 300 is placed on top of a (FIG. 4A)
reference). The flat plate portion 12a includes the suspension band 20 and the pipe 30.
However, in the present embodiment, the front plate 16 and the rear plate 18 serving as reinforcing plates supplement the rigidity against bending in the vertical direction, and reliably prevent the flat plate 12 from being deformed. . Therefore, even if the pipe 300 is placed, the suspension band 20 is maintained without falling down in the previous state.

As described above, the operator does not need to keep holding the pipe 300, and after placing the pipe 300, can free his / her hands and proceed to the next operation. Piping work using hanging hardware, which is a work at height, is facilitated.

Next, the other arm 22b is rotated to close the tube 300 so as to sandwich the tube 300, and the suspension band 20 is fastened to the flat plate 12a. In this operation, after the suspension band 20 is closed, the suspension band 20 is located at an almost overlapping position (see FIG. 3B).
The suspension band fixing bolt 17 is inserted into the fixing hole 25a of the arm end portion 25 and the suspension band fixing hole 23 on the top plate 12 side, and a nut is screwed into the suspension band fixing bolt 17 and tightened. Will be

The tightening of the nut can be performed without applying an extra load to the suspension band fixing bolt 17 and the nut depending on the restraint and the support state of the suspension band 20, and can be easily performed manually by the operator. . Then, the nut is finally tightened with a desired torque by using a tool such as a monkey, so that the suspension of the tube material is easily completed.

A tool is used only once at the end of fastening of the suspension band 20, and there is no troublesome insertion / removal of a tool or a change of a tool especially at a high place. In this way, the operator can end a series of tube material hanging operations very easily.

The above-mentioned operation can be performed in the left-right order or in parallel, so that the hanging bands 20 can be arranged on both the left and right sides as shown in FIG. 4B. It is possible to suspend two pipes.

Further, as shown in FIG.
If the male screw portion 110 of 00 is further extended, another hanging hardware 10 is arranged under one hanging hardware 10, and a maximum of four pipe materials can be held. Another hanging hardware 10
If a conventional turnbuckle is used at the lower end of the hanging bolt 100 instead of the hanging bolt 100, a total of three tubes can be held as shown in FIG. In this manner, a plurality of pipes can be hung by a simple operation on one hanging bolt 100 within a range in which a hanging load and a space are allowed.

FIG. 7 is a perspective view schematically illustrating another embodiment. In the figure, the same reference numerals are given to the same components as those in the above-described embodiment, and the detailed description is given. Description is omitted.

The characteristic feature of the present embodiment is that the top plate 12 is made of a material having a larger elastic modulus or is increased in thickness to increase rigidity and strength. That is, the plate portion 16 and the rear plate portion 18 are not provided. As described above, when it can be confirmed that the design strength is sufficient for holding the pipe material and the mechanical bending is sufficiently small from the material and the cross-sectional shape, the reinforcing plate may not be provided. In this case, in the operation of fastening the suspension band 20 to the top plate 12, the surrounding space when the nut is screwed into the suspension band fixing bolt 17 and tightened becomes wider, and the fastening can be performed more easily.

Next, FIG. 8 is a schematic perspective view showing still another embodiment of the present invention, and a characteristic configuration different from the above-described embodiment lies in the configuration of the frame portion 14. As shown in the figure, the frame portion 14 is formed at the top plate 12 flat plate portion 12a. That is, it is disposed at a position closer to the side edge than the center hole 21 in the flat plate portion 12a. Then, as a major feature, a part (predetermined width, predetermined length) of the flat plate portion 12a from below.
Is rolled, and the protruding portion 14 protrudes above the flat plate portion 12a.
a is formed to form the elongated band-shaped hanging band insertion hole 24. By forming the frame portion 14 by rolling with a press machine or the like, the manufacturing process of the flat plate portion 12 can be simplified.

In the case of this embodiment, when the hanging band 20 in the opened state is locked, the distal end 25 of the lower arm portion is opened in the frame portion 14 of the hanging hardware 10 as shown in FIG. Is partially inserted into the hanging band insertion hole 24 thus formed. As a result, the suspension band 20 maintains its state in which it is not easily dropped while the distal end portion 25 of the arm portion is restrained by the upper end 24a of the suspension band insertion hole 24 and the upper surface 12a of the flat plate portion 12a while receiving gravity vertically downward. Is done. That is, contrary to the above-described FIG. 3B, the corner of the upper surface of the flat plate portion 12a serves as a fulcrum, and the arm tip portion 25, which is an action point, restricts the vertical movement at the upper end 24a of the suspension band insertion hole 24. Is what is done. Other effects when suspending tubing are:
This is the same as in the first embodiment. Therefore, the pipe material can be easily suspended.

FIG. 10 is a schematic perspective view showing still another embodiment. The characteristic configuration of the present embodiment is
That is, a reinforcing structure is provided on the flat plate portion 12a itself.
That is, the front plate portion 16 and the rear plate portion 18 which are the reinforcing plates shown in FIG. 2 are not formed, and the protruding portions 31-1 and 31-2 are formed along both sides in the longitudinal direction of the flat plate portion 12a. is there. For example, the flat portion 1a is rolled to form a reinforcing portion projecting upward at a predetermined height and a predetermined length. As described above, the protruding portions 31-1 and 3-2 serving as reinforcing portions increase the rigidity of the flat plate portion 12, and thus serve to reinforce the flat plate portion 12.

Although not shown, the protrusion 31-
1, 31-2 can be formed so as to protrude to the lower surface side of the flat plate portion 12a. In this case, in the initial temporary support state, the distal end portion 25 of the arm portion is moved to the protruding portions 31-1 and 3-1.
It is also possible to restrict from left and right in 1-2, and stabilization of the temporary support state is also achieved.

In the present embodiment, as in the above-described embodiments, the tool is used only once at the end, and there is no need to insert and remove the tool, and the work of suspending the pipe is easily completed.

It should be noted that the present invention is not limited to the configuration of each of the above embodiments, and various modifications are possible within the scope of the invention. Also, in the manufacturing examples shown in the above embodiments, the flat plate portion 12a and the like are formed by drilling, bending, and rolling, but the whole or a part thereof may be formed as a casting. .
