Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a support device for supporting piping to a side support member via a support member such as a spring hanger.

(Prior Art) Conventionally, in a support device for supporting a pipe on a side support, a lug is welded to the outer periphery of the pipe, and a support member such as a spring hanger is coupled to the lug.

(Problems to be solved by the invention) In the above-mentioned conventional pipe support device, the lug is directly welded to the outer circumference of the pipe, so this work is not easy, and especially in the case of pipes for nuclear power plants, inspection of welded parts is difficult. The problem is that the process is extremely strict and requires a troublesome heat treatment process after welding.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention provides a pipe support device in which a lug 3 is fixed to the pipe P and the lug 3 is laterally supported. , a pair of fastening fittings 1, 1 are provided with lugs 3, 3 at both ends of a semi-annular curved plate 2 along the outer periphery of the pipe P.
are arranged opposite to the outer periphery of the pipe P, a projecting edge 4 is provided on at least one of the upper edge or the lower edge of the lug 3 at a predetermined interval from the base end, and a curved wedge 6 along the outer periphery of the pipe P is provided on both sides. Insert between the pipe P and the tightening fitting 1 from the edge 4 side so as to straddle the tightening fittings 1, 1, and insert the wedge 6 between the end face of the wedge 6 and the edges 4, 4 of the two opposing lugs 3, 3. A holding plate 7 that comes into contact with the holding plate 7 and a receiving plate 5 provided on the opposite side with the lug 3 interposed therebetween are tightened with bolts 8, so that the wedge 6 can be pushed in with the holding plate 7.

(Function) In the pipe support device of the present invention, a pair of clamping fittings 1 are disposed facing each other around the outer periphery of the piping P, and a curved wedge 6 is positioned at the opposing portion of the lug 3 and protrudes so as to straddle both clamping fittings 1. A presser plate 7 is inserted between the pipe P and the clamping fitting 1 from the edge 4 side, and is arranged so as to abut against the end surface of the wedge 6 and the protruding edges 4 of the two lugs 3 facing each other. 7
A bolt 8 is inserted between and a receiving plate 5 provided on the opposite side with the lug 3 in between, and both are tightened, and the wedge 6 is pushed in with the holding plate 7 to fix the tightening fitting 1 to the pipe P. When pressing the wedge 6 with the holding plate 7, one side of the holding plate 7 contacts the end face of the wedge 6, and the other side contacts the protrusion 4 of the lug 3 with a space in between, so that by tightening the bolt 8. A rotational moment is generated in the pressing plate 7 in the direction of pushing the wedge 6, and this force firmly presses the wedge 6.

(Embodiment) FIGS. 1 to 3 show an embodiment in which the present invention is applied to a support device for a vertically rising portion of a pipe. Figure 1 is a perspective view showing how the piping support device is installed;
3 is a plan view, and FIG. 3 is a partial longitudinal sectional front view.

In the figure, reference numeral 1 denotes a pair of fastening fittings, which are provided in pairs on the outer periphery of the pipe P, facing each other. The fastening fitting 1 is formed by providing lugs 3 at both ends of a semi-annular curved plate 2 along the outer periphery of the pipe P. The lugs 3 are connected to each other with bolts or the like, and are supported upwardly by spring hangers or the like (not shown). The lug 3 is formed with a protruding edge 4 projecting upward at a predetermined distance from its base. Furthermore, a horizontal receiving plate 5 is fixed to the lower edge of the corner between the curved plate 2 and the lug 3.

The wedge 6 is curved along the outer periphery of the pipe P, and is inserted between the pipe P and the fastening fitting 1 from above so as to straddle both the fastening fittings 1, 1.

Then, a presser plate 7 is applied so that the lower surfaces of both sides are in contact with the upper end of the wedge 6 and the ridges 4 of the two opposing lugs 3, and the presser plate 7 and the receiving plate 5
A bolt 8 is inserted through the bolt 8, and the holding plate 7 and the receiving plate 5 are tightened by the bolt 8. Therefore,
The wedge 6 is pushed down by the holding plate 7 and press-fitted between the pipe P and the clamping fitting 1, so that the clamping fitting 1 is fixed to the pipe P.

In the pipe support device of this embodiment, the pipe P
A pair of clamping fittings 1 are arranged facing each other on the outer periphery of the lug 3, and a curved wedge 6 is inserted between the piping P and the clamping fitting 1 from above so as to be located on the opposite side of the lug 3 and spanning both clamping fittings 1,1. do. A presser plate 7 is arranged so that the lower surface of one side is in contact with the upper end surface of this wedge 6, and the lower surface of the other side is in contact with the protruding edges 4, 4 of the two opposing lugs 3, 3. A bolt 8 is inserted through the plate 5 and tightened, and the wedge 6 is pushed down by the holding plate 7 to be press-fitted between the clamping metal fitting 1 and the pipe P, and the clamping metal fitting 1 is fixed to the piping P. When the wedge 6 is pressed down by the holding plate 7, one side of the holding plate 7 comes into contact with the upper end surface of the wedge 6, and the other side comes into contact with the ridge 4 of the lug 3 with a space S in between, so that the bolt By tightening 8, a rotational moment is generated in the direction of pushing the wedge 6 into the holding plate 7 as shown by the arrow, and this force allows the wedge 6 to be easily pushed in and firmly pressed at all times.

Note that the present invention is not limited to the illustrated embodiment; for example, the receiving plate 5 may be made separate from the fastening fitting 1, and a projecting edge may be formed on the other side of the lug, and Instead of the receiving plate 5, a holding plate may be provided on the other side, and the holding plates on both sides may be tightened with bolts, and the wedge may be press-fitted from the other side as well. Furthermore, it can be applied not only to vertically rising parts of piping, but also to supporting horizontal parts and all other places.

(Effects of the invention) As described above, in the present invention, in the support device for the piping P in which the lug 3 is fixed to the piping P and the lug 3 is supported laterally, a half-length along the outer circumference of the piping P is provided. A pair of fastening fittings 1, 1 with lugs 3, 3 provided at both ends of an annular curved plate 2 are arranged facing each other on the outer periphery of the pipe P, and at least one of the upper edge or the lower edge of the lugs 3 is provided at a predetermined distance from the base end. A curved wedge 6 along the outer periphery of the pipe P is inserted between the pipe P and the clamping fitting 1 from the flange 4 side so as to straddle both the clamping fittings 1, 1. The end face of the wedge 6 and the two opposing lugs 3,
3, and a receiving plate 5 provided on the opposite side with the lug 3 in between, are tightened with bolts 8, and the wedge 6 is secured with the holding plate 7.
Because it is configured so that it can be pushed in, lug 3 is attached to the pipe P.
can be fixed without welding, the wedge 6 can be easily pushed in by the rotational moment of the holding plate 7, and the wedge 6 can be firmly fixed.
