Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nut-shaped member suitable for mounting on a long bolt, and a supporting tool for applying the nut-shaped member to a ceiling bolt to be hung on a ceiling structure of a building. It is about.

[0002]

2. Description of the Related Art Conventionally, even when a nut is mounted in the middle of a long bolt, it has conventionally been necessary to fit the nut to the end of the bolt, rotate it to a desired position, and proceed with time. For example, as shown in FIG. 3, the attachment of the ceiling frame member 4 supporting hanging metal member 3 to the long hanging bolt 2 hanging on the ceiling structure 1 is conventionally performed by positioning the nut N ₁ on the hanging bolt 2. It was done by setting it there through the hole of the bent portion 3a of the hanging hardware 3 and tightening another nut N ₂ from below. However, this suspension bolt 2
Are hung vertically and horizontally on the ceiling structure 1 at intervals of 900 mm, the number of them is very large, and therefore the mounting work of the hanging hardware 3 is enormous. Therefore, the applicant
A leaf spring nut 7 shown in FIGS. 4 and 5 was developed and filed so that the hanging hardware 3 can be easily positioned and fixed to the hanging bolt 2 (see Japanese Utility Model Publication No. 2-35045).

The leaf spring nut 7 has an internal thread 71a formed inside and an opening 71 parallel to the axis at one side.
An elastic tubular nut portion 71 having b and two plate-like knobs 7 which are attached to the opposite side of the nut portion 71 on the opposite side to the opening portion 71b and which are attached at their base end portions and which are opened at appropriate angles and project from each other.
2, a nut-shaped cutout portion 73 is formed on the side portion of the nut portion 71 at a right angle to the axis, and the cutout portion 73 extends to the vicinity of the base end portion of each knob. ..

[0004]

In the leaf spring nut 7 described above, as shown in FIG. 5, the bent portion 3a of the hanging hardware 3 is inserted into the notch portion 73, the knob 72 is closed, and the opening portion 71b is further opened. After opening and setting the inner diameter of the nut portion 71 to be larger than the outer diameter of the hanging bolt 2, the leaf spring nut 7 and the hanging hardware 3 are set and positioned on the hanging bolt 2, and then the knob 72 is released to lift the hanging hardware 3. Although it is fixed to 2, the position may shift when a very large external force is applied to the hanging hardware 3.

According to the present invention, a nut-shaped member that can be easily mounted in a target position of a long bolt in a short time, and by applying the nut-shaped member, even if a large external force is applied, the position shift of the hanging metal object with respect to the hanging bolt can be achieved. It is an object of the present invention to provide a ceiling frame support which does not occur at all.

[0006]

In order to achieve the above object, in the nut-shaped member of the present invention, a female screw having a diameter larger than the outer diameter of the bolt to be mounted is formed at the center thereof, and the central portion is provided at the side portion. The main fixing member has a nut-shaped outer shape in which a female screw penetrating the female screw is formed, and a bolt screwed into the side female screw. In addition to the above-mentioned structure, the ceiling frame member support is configured such that the upper bent portion of the hanging metal member is rotatably attached to the main fixing member.

[0007]

[Operation] In the nut-shaped member configured as described above and the ceiling frame member support tool to which the nut-shaped member is applied, the main fixing member is slid at the target position of the bolt to be mounted, and the bolt is tightened. Is screwed into a female screw at the center of the main fixing member. Then, when the main fixing member is rotated, the object is tightened just like a normal nut. Also, when the hanging hardware is rotatably attached to the main fixing member and used as a ceiling frame member support tool, after the positioning with respect to the hanging bolt, the main fixing member does not rotate anymore by tightening the bolt further, The gap will not occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIG.

Generally, in the ceiling of a building, a lightweight iron ceiling frame member 4 is hung from a long hanging bolt 2 hung from a ceiling structure 1 through a hanging metal member 3, and a base plate is attached below the ceiling frame member 4. It is completed by applying lath mortar coating to the lower surface.

The nut-shaped member of the present invention comprises a main fixing member 5
And a bolt 6, for example, a hanging hardware 3
In combination with the above, it is used as a part of the ceiling frame member support in the above ceiling assembly.

The hanging hardware 3 is no different from the conventional one shown in FIGS. 3 and 4, and has a hole 31 through which the hanging bolt 2 is inserted.
Has an upper bent portion 3a.

The main fixing member 5 is formed by integrally forming a hooking portion 51 and a mounting portion 52. The hook 51 is
The outer shape is a nut shape, and a through hole having a diameter larger than the outer diameter of the hanging bolt 2 is provided at the center. A female screw 51a is formed in the through hole. The inner diameter of the female screw 51a may be about 9.1 mm, for example, when the hanging bolt 2 has an outer diameter of 8.9 mm. Further, a hole that penetrates to the central female screw 51a is formed on one side surface of the hook portion 51, and a female screw 51b is formed in the hole.
First, the mounting portion 52 is, as shown by the alternate long and short dash line in FIG.
It has a tubular shape slightly smaller than the inner diameter of the hole 31 of the hanging hardware 3, and is flattened as shown by the solid line by pressing the fitting 3 after fitting it therein. Even if integrated in this state, the main fixing member 5 needs to be able to rotate with respect to the hanging hardware 3. When the main fixing member 5 and the bolt 6 are used alone as a nut-shaped member, the mounting portion 52 may not be provided.

The bolt 6 is screwed into a female screw 51b formed on one side surface of the main fixing member 5.

When using the main fixing member 5 and the bolt 6 as a nut, first, the bolt 2 to be mounted is passed through the central hole of the main fixing member 5 and slid to a position close to the target position. When tightening the bolt 6 in that state, the target bolt 2
Is moved from the position 2 shown by the solid line to the position 2'shown by the dotted line in FIG. 2, and is screwed with the female screw 51a of the main fixing member 5. When the main fixing member 5 is rotated in this state, the object can be tightened just like a normal nut. After that, when the bolt 6 is further tightened, the main fixing member 5 and the bolt 6 do not rotate with respect to the mounting target bolt 2. Further, if the hanging hardware 3 is fitted into the mounting portion 52 of the main fixing member 5 and is pressed and integrated, it can be used similarly as a ceiling frame member support tool. In this case, tightening the bolt 6 further after the positioning with respect to the hanging bolt 2 is particularly effective for preventing the positional deviation of the hanging hardware 3.

[0015]

Since the present invention is constructed as described above, it has the following effects.

That is, even if the bolt is long, after sliding the main fixing member to the target position of the bolt to be mounted,
By tightening the bolt, it can be used as a normal nut. Moreover, the mounting can be performed easily in a short time. When the hanging metal object is rotatably attached to the main fixing member and is used as a ceiling frame member supporting tool, in addition to the above effects, the hanging metal object shown in FIG. It is possible to obtain the same supporting strength as that of the conventional assembly, and there is no displacement.
