Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention is a method for moving lighting equipment, wiring parts, etc. from L-shaped steel, thin-shaped steel, and other construction materials in building structures in any direction. This invention relates to a suspension support fitting that is tilted and suspended.

(Prior Art) Conventionally, in order to suspend and support various wiring devices from various construction materials, the applicant has proposed, for example, as shown in FIG. To provide a suspension support fitting equipped with a nut curved in an arc shape to enable dynamic adjustment. This suspension support fitting includes a support fitting main body 101 having an approximately U-shape on the side that is screwed and press-fastened to a predetermined construction material S, and a substantially U-shaped suspension fitting in the front that is swingably supported by the support fitting main body 101. Hanging metal fitting 102 and this hanging metal fitting 1
A hanging rod member B inserted through the curved bottom wall of No. 02 is screwed in, and an engagement nut disc 103 is engaged with the inner surface of the curved bottom wall. Then, the engagement nut plate 103
is curved in an arc so as to be in close contact with the inner surface of the curved bottom wall of the hanging fitting 102 and to slide in correspondence with the inclination of the hanging rod member B to be supported, and has a female thread into which the hanging rod member B is screwed. It has been formed.

In order to be able to provide this kind of conventional engagement nut disk 103 at a low cost, a suitably thick sheet material is used as a material, and this is pressed and bent.
Further, the female thread is formed as a tap structure.

Furthermore, a fixing nut 104 is screwed into the outer surface of the curved bottom wall of the hanging fitting 102 in order to securely fix the construction material S to the hanging fitting 102, and the bottom wall is clamped together with the engaging nut disk 103. In this fixing nut 104, a chrysanthemum washer 105 is interposed between the fixing nut 104 and the bottom wall of the suspension fitting 102 in order to prevent the nut from loosening.

On the other hand, in addition to this, the applicant has
Suspension support fittings such as 61695 publication and Utility Model Publication No. 47-5683 are also provided. Of these, Utsukai Showa 55-
The suspension support fitting of Publication No. 61695 has a main body with a substantially U-shaped side surface in which an opening for sandwiching a specified construction material is formed between the upper and lower plates facing each other, and a tip on the side of the construction material sandwiched within the opening. In this mounting bracket, a shock absorbing material is interposed between the upper plate and a nut member to which the fixing screw is screwed, in a mounting bracket consisting of a fixing screw provided on an upper plate so as to be movable forward and backward for pressure fixing.

In addition, the suspension support metal fitting disclosed in Japanese Utility Model Publication No. 47-5683 has a tightening bolt screwed into a screw hole in the upper plate, a notch with a flange on both left and right plates, and a lower end of both left and right plates. The upper ends of the left and right plates of the angle adjustment fitting are fitted onto the lower ends of the left and right plates of the metal fitting body in which a pivot hole is bored in the metal fitting body, and a ring is interposed between the left and right plates of the metal fitting body to form the angle adjustment fitting. is pivotally attached to the lower ends of the left and right plates of the metal fitting body, and the upper end of the hanging bolt with a nut screwed into the engagement hole provided at the lower end of the angle adjusting metal fitting is engaged, and the angle adjusting metal fitting is rotated. It is constructed by detachably attaching a hanging bolt to the lower end.

However, according to the structure (FIG. 4) of the engagement nut plate 103 formed by conventional press working, since the tap is curved after being formed, the suspension fitting 102 is When screwing in the hanging rod member B from the outside, the engaging nut board 1
There was a problem in that the taps on the curved surface of 03 itself hit, making it difficult to screw in the hanging rod member B smoothly.

Also, a chrysanthemum washer 1 for preventing loosening of the hanging rod member B.
05 has its rough surface abutted against the outer surface of the curved bottom wall of the hanging fitting 102, but since the curved bottom wall itself is curved, the actual contact area is extremely small.
The loosening prevention function of the hanging rod member B was not fully exhibited.

On the other hand, in the suspension support metal fitting disclosed in Japanese Utility Model Application Publication No. 55-61695, although the suspension rod member is supported from the suspension support with a shock absorbing material interposed, the structure is such that the suspension support is sandwiched and tightened. As a result, when vibration or shock is applied, the shock absorber moves slightly upward, and the hanging rod member to which the shock absorber is screwed tends to come off from the shock absorber.

In addition, with the suspension support metal fittings such as those disclosed in Japanese Utility Model Publication No. 47-5683, although the angle adjustment metal fittings can be moved back and forth,
Since the hanging bolt was fixed to the angle adjustment fitting, the hanging bolt itself could not be moved from side to side.

Therefore, this idea was devised in view of the above points, and it is possible to secure a sufficient length for screwing in the hanging rod member, and also to make it easy to screw in to ensure reliable engagement and support. The purpose of the present invention is to provide a suspension support fitting which improves stability by increasing the contact area of a washer to the outer surface of a curved bottom wall of the fitting and further increases tightening by screwing.

[Structure of the invention] (Means for solving the problem) In order to achieve the above-mentioned purpose, this invention includes a supporting metal body whose side surface is approximately U-shaped and which is screwed and compressed to a predetermined construction material; A hanging metal fitting which is approximately U-shaped from the front and is swingably supported by the support metal body, and a hanging rod member inserted through the curved bottom wall of this hanging metal fitting is screwed into and engaged with the inner surface of the curved bottom wall. In the suspension support fitting, the suspension fitting is formed by providing an elongated suspension hole in the curved bottom wall, which is long in the left-right direction, and the nut body includes: It is thick in the direction in which the hanging rod member is screwed in, and is formed in a cylindrical shape with a curved outer circumferential surface similar to the curvature of the inner surface of the curved bottom wall of the hanging fitting, and a female thread into which the hanging rod member is screwed is drilled in the transverse direction. A clamping nut that clamps and clamps the curved bottom wall together with the nut body is screwed into the upper part of the hanging rod member, and a circular boss that contacts the outer surface of the curved bottom wall is inserted between the clamping nut and the curved bottom wall. A contact protrusion of the shape 4 is provided on the periphery surrounding the hanging rod member.
The present invention is characterized in that a washer formed by the holding nut and the washer is interposed, and a chrysanthemum washer is interposed between the clamping nut and the washer.

(Function) In the hanging support metal fitting according to this invention, the support metal body is attached to the construction material by tightening the mounting screws, and lighting equipment, etc. are attached to the hanging metal fitting connected to the support metal body. A hanging rod member for suspending a predetermined wiring device such as a wiring component is engaged and supported.

The suspension rod member is engaged with and supported by the suspension metal fitting by screwing into the suspension rod member a nut body and a clamping nut arranged inside and outside the curved bottom wall of the suspension metal fitting, and clamping and compressing the curved bottom wall.

At this time, since the nut body is thick, the hanging rod member can be screwed in in the same way as a normal nut.
In addition, the circular boss-shaped abutting protrusion of the washer interposed between the clamping nut and the curved bottom wall substantially increases the contact area with the outer surface of the curved bottom wall, and prevents the curved part from bending as the hanging rod member swings. Even if it moves on the outer surface of the bottom wall, it always maintains contact with it. By maintaining the contact state, the nut body and the clamping nut can stably clamp the curved bottom wall.

The nut body is formed into a cylindrical shape having a curved outer circumferential surface that slides into contact with the inner surface of the curved bottom wall of the hanging fitting, and has a female thread bored in the transverse direction into which the hanging rod member is screwed. Therefore, when placed inside the curved bottom wall of the hanging bracket, the nut body itself is prevented from idling when the hanging rod member is screwed in, ensuring a smooth and secure connection, and allowing But it can be screwed in.
