Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling hanging metal fitting having a vibration-proof structure for supporting a ceiling base member by suspending it from a horizontal member arranged above the ceiling.

[0002]

2. Description of the Related Art As a ceiling hanging metal fitting of a vibration-proof structure, which is supported by suspending a base member of the ceiling from a horizontal member arranged above the ceiling, the one shown in FIG. 4 has been conventionally known. In the illustrated conventional ceiling hanging metal fitting, the upper end flat portion of the upper battlement plate bolt 1 is fixed to a horizontal member, such as a joist or a lumber receiver, arranged above the ceiling with a nail (not shown). Has become. An annular hanger 2 is fixed to the bolt portion of the upper battledore bolt 1 by nuts 3 and 4.

A lower battledore bolt 5 is suspended at the lower end of the hanger 2 by the bolt portion. Nuts 6 and 7 are screwed into the bolt portion of the lower battledore bolt 5, and a vibration proof rubber 8 is provided between the nut 7 and the hanger 2.
Has been inserted. A ceiling base member such as a field edge is fixed to the lower flat portion of the lower battledore bolt 5 with a nail. Then, the ceiling material is fixed to the ceiling base member from below with nails or the like.

In the above-mentioned conventional ceiling hanging metal fitting,
By inserting the anti-vibration rubber 8 between the nut 7 and the hanger 2, transmission of vibration such as sound between the hanger 2 and the lower battlement plate bolt 5 is suppressed. As a result, the structure is such that vibration such as footsteps above the floor can be prevented from being transmitted to the ceiling below the floor.

[0005]

However, in the above-mentioned conventional ceiling hanging metal fitting, there are two adjustment points by the nut, that is, the upper battlement plate bolt and the lower battlement plate bolt, which makes the handling troublesome. Was there. Further, since the lower battledore bolt 5 is merely suspended from the hanger 2 and is not fixed, the lower battledore bolt 5 floats up relative to the hanger 2 when pushed up from below.

[0006] Therefore, when the ceiling material is hammered from below to the ceiling base material such as a field edge fixed to the lower end flat portion of the lower battlement board bolt 5, the ceiling base material and the lower battlement board bolt 5 are lifted, and the ceiling material is removed. Workability was poor because it was not possible to hit the ceiling base member efficiently. An object of the present invention is to provide a ceiling hanging metal fitting having a vibration-proof structure that is easy to handle and has excellent workability in the work of hitting a ceiling material.

[0007]

In order to achieve the above object, in a ceiling hanging fitting according to the present invention, a flat lower end portion to which a base member of the ceiling is fixed, and an outer circumference extending upward from the lower end portion are provided. A suspension bolt member having a bolt portion with a screw threaded on it, and a carrying portion that is fixed to a horizontal member disposed above the ceiling and carries the hanging bolt member. A bracket member having a loose insertion hole through which the bolt portion of the hanging bolt member is inserted with a gap, and an upper vibration isolating member and a lower vibration isolating member having an insertion hole through which the bolt portion of the hanging bolt member is inserted, An upper nut and a lower nut screwed to the bolt portion of the hanging bolt member are provided, and a lower vibration isolating member and a carrying portion of the bracket member are provided between the upper nut and the lower nut screwed to the bolt portion of the hanging bolt member. And above Vibration isolating member has a structure that is inserted from the lower end in this order.

That is, the hanging bolt member has only one adjustment position by the nut, and the hanging bolt member can be fixed to the bracket member by tightening the upper nut and the lower nut. There is.

[0009]

With such a structure, according to the present invention, the number of adjusting points by the nuts is reduced, so that it is easy to handle and the suspension bolt is fixed to the bracket member. Therefore, even when the suspension bolt is pushed up from below, the suspension bolt does not float up relative to the bracket member.

Further, if at least one of the upper vibration isolating member and the lower vibration isolating member is provided with an annular projection around the insertion hole, the annular projection is fitted into the loose insertion hole formed in the carrying portion of the bracket member. It is preferable since it is possible to prevent the bracket member and the hanging bolt from directly contacting each other.

Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 is a front view showing an embodiment of a ceiling hanging metal fitting according to the present invention, FIG. 2 is a partial cross-sectional left side view showing a usage state of the ceiling hanging metal fitting according to the present invention shown in FIG. 1, and FIG. It is the perspective view which showed an example of the vibration isolator concerning this.

As shown in these drawings, in the ceiling hanging fitting according to the present invention, the ceiling base member such as the field edge 11 is provided with the hanging bolt 12 fixed to the lower end portion 12a. The lower end portion 12a of the hanging bolt 12 is formed flat so as to easily fix the ceiling base member such as the field edge 11.
A hole 12b into which the nail 13 is inserted is formed in the lower end portion 12a so that the ceiling base member such as the field edge 11 can be fixed to the lower end portion 12a of the hanging bolt 12 by the nail 13. .

The hanging bolt 12 has a bolt portion 12c extending upward from a lower end portion 12a thereof and having a threaded outer periphery. The hanging bolt member 12 is the bolt portion 12
It is suspended and supported by the bracket member 15 at c. As is clear from FIG. 2, the bracket member 15 is a metal member that is fixed to a horizontal member such as a joist 16 provided above the ceiling with a nail 17 or the like. A hole 15b into which the nail 17 is inserted is formed in a portion of the bracket member 15 which is to be hit on the horizontal member, so that the bracket 17 can fix the bracket member 15 to the horizontal member such as the joist 16 or the like. .

The bracket member 15 is formed with a suspension support portion 15a which extends horizontally, and the suspension support portion 15a is formed with a free insertion hole 15c through which the bolt portion 12c of the suspension bolt member 12 is inserted with a gap. ing. Hanging branch 1
An upper anti-vibration member 18 and a lower anti-vibration member 19 are provided above and below 5a, respectively. These anti-vibration members are formed of anti-vibration rubber or the like, and are used for the bolt portion 12c of the hanging bolt member 12.
Insertion holes 18a and 19a, through which is inserted, are formed in each.

The bolt portion 12c of the hanging bolt member 12 is
As shown in the drawing, these are inserted into the insertion holes 18a and 19a of the vibration isolation members 16 and 17 and the free insertion hole 15c of the suspension support portion 15a. Then, by tightening the wing nuts 20 and 21 screwed into the bolt portion 12c from above the upper vibration isolating member 18 and below the lower vibration isolating member 19, respectively, the hanging bolt member 12 is attached to the bracket member 15 at the bolt portion 12c. It is fixed to the suspension support portion 15a and suspended.

At this time, as described above, the bolt portion 12
Since a gap is provided between the c and the suspension support portion 15a, direct contact between the bracket member 15 and the suspension bolt member 12 can be avoided, and transmission of sound and vibration between them can be prevented. Further, since the vibration isolation members 18 and 19 are inserted between the wing nuts 20 and 21 and the suspension support portion 15a, transmission of sound and vibration between the bracket member 15 and the suspension bolt member 12 is suppressed. .

Further, as shown in FIG. 3, the vibration isolating member 1
8 and 19 through holes 18a, 19
Around the a, the bolt portion 12c in the loose insertion hole 15c formed in the suspension support portion 15a of the bracket member 15 and the suspension support portion 15a.
By forming the annular protrusions 18b and 19b that fit into the gap between the bracket member 15 and the hanging bolt member 12, it is possible to reliably prevent contact between the bracket member 15 and the hanging bolt member 12, and to reliably transmit sound and vibration between them. it can.

Incidentally, seat ridges 22 and 23 are inserted between the wing nut 20 and the vibration isolating member 18 and between the wing nut 21 and the vibration isolating member 19, respectively. This is because the pressure when the wing nut is tightened is concentrated on the contact portion between the wing nut and the vibration isolating member, and the vibration isolating member is prevented from being unnecessarily deformed. Further, it is expected that the upper vibration isolating member 18 will be gradually deformed because it continues to receive a load for a long period of time, and its vibration isolating performance will deteriorate. Therefore, in this embodiment,
In order to prevent the deformation of the upper vibration isolating member 18 as much as possible, an enclosure 15d is formed on the outer peripheral portion of the suspension support portion 15a of the bracket member 15 so that the upper vibration isolating member 18 can be fitted tightly. As a result, it is possible to prevent the upper vibration isolation member 18 from being deformed and protruding laterally.

By the way, when tightening the wing nuts 20 and 21, it is possible to adjust the relative height of the hanging bolt member 12 with respect to the bracket member 15. In the ceiling hanging metal fitting according to the present invention, the nut is used. Since there is only one adjustment point on the bolt portion 12c of the hanging bolt member 12, the number of adjustment points is smaller than that of the conventional ceiling hanging metal fitting, and the handling is easy.

Further, in the conventional ceiling hanging metal fitting, when the ceiling material is hammered from below onto the ceiling base member such as a field edge fixed to the lower end flat portion of the lower battlement plate bolt 5, the ceiling base member and the lower battlement plate bolt 5 are It floated up and the ceiling material could not be efficiently hit on the ceiling base material,
Although the workability was poor (see FIG. 4), in the ceiling hanging fitting according to the present invention, as described above, the hanging bolt member 1
Since 2 is fixed to the bracket member 15,
Even if the hanging bolt member 12 is pushed up from below, the hanging bolt member 12 does not float up relative to the bracket member 15.

Therefore, when the ceiling material 24 is struck from below with a nail or the like to the ceiling underlayer member such as the field edge 11 fixed to the lower end portion 12a of the hanging bolt member 12, the ceiling underlayer member and the hanging bolt member 12 float up. As a result, the ceiling material can be more efficiently hit on the ceiling base member as compared with the conventional case. In the above-described embodiment of the present invention, the wing nuts 20 and 21 are used as the nuts screwed into the bolt portion 12c of the hanging bolt member 12. this is,
This is because the wing nut can be tightened without using a tightening tool such as a wrench and is excellent in workability. Therefore, if this workability is sacrificed, a normal hexagon nut may be used instead of the wing nut.

[0022]

As described above, according to the present invention, the number of adjustment points by the nuts is reduced as compared with the conventional ceiling hanging metal fitting, so that there is an advantage that the handling is easy. Further, since the suspension bolt is fixed to the bracket member, the suspension bolt does not float up relative to the bracket member even when the suspension bolt is pushed up from below. Therefore, when the ceiling material is struck from below with a nail or the like to the ceiling foundation member such as a field edge fixed to the lower end portion of the suspension bolt member, the ceiling foundation member and the suspension bolt member do not float up, and the ceiling ceiling member is smaller than in the past The material can be efficiently hit on the ceiling base member.
