Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a hanging bracket for suspending and supporting an air conditioner and various types of piping from a ceiling surface.

[0002]

[Problems to be solved by the invention]

 Conventional suspension fittings are provided with bolt insertion holes facing the upper and lower plates of a frame member obtained by bending a metal plate.Therefore, the opening surface is narrow and the insertion and rotation of a nut rotation tool such as a wrench can be performed. It was troublesome. The object of the present invention is to provide a ceiling hanging bracket capable of rotating a rotating tool of a fastening nut in a range of approximately 180 ° and having the same outer shape and appearance as a conventional hanging bracket when fully fastened.

[0003]

[Means for Solving the Problems]

 The ceiling suspension bracket according to the present invention includes a first U-shaped member in which a first upper plate portion having a bolt hole formed therein and a first lower plate portion are connected by a first vertical side plate, and a first U-shaped member having a bolt hole formed therein. A second upper plate portion and a second U-shaped member formed by connecting the second lower plate portion with a second vertical side plate, wherein the bolt holes of the first and second upper plate portions and the first and second lower plate portions are formed. A ceiling metal fitting wherein the first and second U-shaped members are rotatably connected by fitting eyelets to each of the bolt holes of the first and second U-shaped members. Is turned to a position convenient for the nut fastening operation, and the temporary tightening is easily performed. Then, the vertical side plate of the second rotating member is rotated so as to face the vertical side plate of the first U-shaped member, and the main tightening is performed. It is fixed. In addition, reinforcing ribs are provided on one side of the first upper plate and the first lower plate so as to face each other, and these are welded and connected with the reinforcing side plates, so that a load resistance equal to or higher than that of the frame-shaped hanging bracket is obtained. Gain. In the present invention, by providing a vibration-proof material such as a rubber bush and a washer beyond the height of the reinforcing rib of the first lower plate portion, the rotation of the fastening nut can be further facilitated together with vibration-proof. In the present invention, the hanging bracket is assembled at the site using a grommet having no lower end folded (caulked) since the first and second ribs are merely rotatably connected by the grommet. You can also attach.

[Embodiment of the invention]

 In the figure, reference numeral 1 denotes a rectangular first upper plate portion, in which a bolt hole 2 is formed at a center portion, and a bent reinforcing rib 3 is formed on one side edge. Reference numeral 4 denotes a first vertical side plate, and reference numeral 5 denotes a first lower plate portion, and a corner C may be cut off or an arc portion. Reference numeral 6 denotes a bolt hole drilled immediately below the bolt hole 2, and reference numeral 7 denotes a reinforcing rib provided to face the reinforcing rib 3. Each reinforcing rib is joined to the reinforcing side plate 4A by spot welding or the like. The upper plate, the side plate and the lower plate are formed by bending a metal plate, and constitute a first U-shaped member A. B is a second U-shaped member. A second upper plate 9 and a second lower plate 10 are formed at both ends of the second side plate 8 by bending, and bolt holes 11 and 12 are formed. Bolt holes (eyelet fitting insertion holes) 2, 11 and 6, 12 of the first and second U-shaped members are respectively aligned, and eyelet fittings 13, 14 are fitted and rotatably connected. . In the present invention, the second upper plate portion 9 is in contact with the lower surface of the first upper plate portion 1, but the second lower plate portion 10 is the upper surface of the first lower plate portion 5. It may be.

[0005] The hanging bracket according to the present invention is configured such that a first U-shaped member A and a second U-shaped member B are temporarily fastened to a ceiling P by a nut 18 in a state of being bent at right angles as shown in FIGS. After T is inserted through the eyelet fitting 14, the nut 17 is temporarily tightened. In this case, the rotary tool has a rotation range of approximately 180 °. Next, the second U-shaped member B is returned to the original state, and the state shown in FIG. In FIG. 1, reference numeral 15 denotes a rubber bush for vibration isolation, and reference numeral 16 denotes a washer, which is provided at a height higher than the height of the reinforcing rib 7, so that the rotation of the nut 17 can be further facilitated and a vibration isolation effect can be obtained.

[0006]

[Effect of the invention]

 The product according to the present invention can easily perform the fastening operation by widening the rotation range of the nut of the suspension bolt, and is suitable as a relatively low-load ceiling suspension bracket.
