Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible cleat for supporting instrumentation pipes installed at a nuclear power plant or the like at a predetermined interval, and more particularly to a pipe support when the instrumentation pipes are different from the standard cleats. The present invention relates to a universal cleat for instrumentation piping suitable for repair of a vehicle.

[0002]

2. Description of the Related Art A conventional instrumentation pipe 1 is supported at regular intervals by a standard cleat 100 as shown in FIG. As shown in FIG. 8, the standard cleat 100 receives the instrumentation pipe 1 in the pipe receiving portion 102 of the Z-shaped steel support member 101, and has a spectacle shape having concave portions 103 provided at intervals between the pipes 110. The pipe 110 is positioned in the recess 103, and the standard cleat 100 is fixed to the support member 101 by bolts 104 between the pipes 110.

[0003]

However, the conventional standard cleat 100 cannot be used in the case where the pipe spacing is not uniform, such as existing pipes, because the pipe spacing is constant. In order to improve this, it is conceivable to repair the pipes so as to make the intervals between the pipes, but the construction cost is too high. In addition, since the instrumentation pipe support is repaired by using a standard cleat with a fixed pipe interval, there is a problem that the pipe 110 is cut and welded and connected with the coupling 105. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, reduce the cost of pipe repair, and provide a cleat for instrumentation piping that can cope with uneven pipe spacing.

[0004]

According to a first aspect of the present invention, there is provided a universal cleat for an instrumentation pipe, comprising: a support member having a pipe support having a receiving surface of an instrumentation pipe in which a plurality of pipes are arranged; A partition plate inserted between the pipes, a pressing member arranged in parallel with the pipe support with the partition plate therebetween, and fixing means for integrating the pressing member and the support member are provided. The presser member is provided with a presser member passing portion that restricts movement of the presser member in a direction parallel to the instrumentation pipe and permits movement in a direction crossing the instrumentation pipe.

[0005]

According to the first aspect of the present invention, by adopting a flexible cleat, a partition plate is inserted between the pipes in the case of irregular pipe spacing, particularly in the existing pipe, and the partition plate is interposed. Then, the holding member is fixed to the supporting member, so that it is not necessary to repair the pipe by coupling after the pipe is cut and repaired to the standard cleat as in the conventional art, and the construction cost can be reduced.

[0006]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an instrumentation piping diagram to which the present invention is applied, and FIG. 2 is a perspective view of an instrumentation piping universal cleat according to the present invention. The instrumentation pipe 1 is arranged in a state where a plurality of pipes 10 are aligned, and a standard cleat 2 is used in a place supporting at a standard interval, and in a place supporting at a different interval from the standard interval. Sweat cleat 3
Is used.

[0007] The flexible cleat 3 connects the instrumentation pipe 1 to the pipe 10
The partition plate 40 is inserted between the support members 30 and supported by the support member 30, and the holding member 50 is positioned above the instrumentation pipe 1 with the partition plate 40 therebetween.
Is fixed and integrated. Support member 30
Is a pipe support 31 having a receiving surface 31a of the instrumentation pipe 1,
It is made of a Z-section steel formed from a fixing portion 32 for fixing to a floor or a wall, and a connecting portion 33 for connecting the pipe supporting portion 31 and the fixing portion 32. A partition plate 40 is fixed to the pipe supporting portion 31. A plurality of bolt holes 34 are provided.

The partition plate 40 is made of a thin plate material. As shown in FIG. 3, an open groove 41 is formed on the upper side, and an insertion groove 42 through which a pressing plate 51 having a width larger than the groove width is formed at the bottom of the groove. Is provided. FIG. 4 shows a modification of the partition plate 40. This example has a structure in which a slit-like insertion hole 43 through which the holding plate 51 penetrates is formed. Here, the insertion groove 4
2 and the insertion hole 43 restrict movement of the presser plate 51 in a direction parallel to the instrumentation pipe 1 and allow movement in a direction crossing the instrumentation pipe 1. Corresponds to a pressing member passing portion.

The holding member 50 has a structure in which the partitioning plate 40 is pressed and fixed to the support member 30 according to the width of the instrumentation pipe 1, and the instrumentation pipe 1 is integrated with the support member 30. In the present example, a holding plate 51 that passes through the groove 42 or the insertion hole 43 of the partition plate 40 is configured. The holding plate 51
The partition plate 40 is formed to have substantially the same length as the support member 30.
A screw hole 52 corresponding to the screw hole 34 of the support member 30 is formed in the vicinity of both ends in the length direction and at an intermediate portion so that the screw hole 52 can be loosely inserted into the groove 42 or the insertion hole 43 of the support member 30. Has been established. A bolt 60 as fixing means is passed through the screw holes 52 and 34, a collar 61 and a spring washer 62 are inserted from below, and tightened with a nut 63.

Next, the use of the adjustable cleat of this embodiment will be described. In FIG. 2, a support member 30 is disposed at a position supporting the instrumentation pipe 1, and the instrumentation pipe 1 is connected to a pipe support 31.
And insert the partition plate 40 between the pipes 10. However, the partition plate 40 is not inserted in a portion where the intermediate screw hole 52 exists. The partition plate 40 is adjusted by inserting one sheet between the pipes 10 or by inserting a plurality of sheets in a stacked manner in accordance with the interval between the pipes 10. After inserting the partition plate 40, the holding plate 50
Through the groove 42 (or the insertion hole 43) of the partition plate 40 on one end side, and out to the other end side. The bolt holes 60 are passed through the screw holes 52, 34 at both ends, and the bolt holes 60 are passed through the intermediate screw holes 52, 34 between the adjacent pipes 10, so that each bolt 6
Insert a collar 61 and a spring washer 62 from the back side of the pipe support 31 and tighten them with nuts 63. By bolting the middle of the holding plate 50, the center portion warps outward and the partition plate 40 does not separate from the receiving surface 31a of the tube 10 and floats. The usage example shown in FIG.
When there is a large space between the adjacent pipes 10, a short pipe 11 can be inserted in place of the partition plate 40 to support the pipe. The short pipe 11 has a length substantially equal to the width of the pipe support 31.

FIG. 6 is a perspective view showing another embodiment of the present invention. The same components as those in the embodiment shown in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted as appropriate. In the present embodiment, the instrumentation pipe 1 is mounted on a cradle 70 separate from the support member 30, and the cradle 70 is fixed to the support member 30. The cradle fitting 70 is formed by sheet metal processing into a U-shaped cross section, and a screw hole 71 corresponding to the cradle bracket fixing screw hole 34 of the support member 30 is provided near both ends, and a screw hole 52 of the presser plate 50 is provided inside thereof. Are provided with screw holes 72 for fixing the holding plate.

When using the free cleat, the instrumentation pipe 1 is first attached to the cradle metal fitting 70, and the partition plate 40 is provided between the pipes.
Is inserted into the partition plate 40, the bolt 60A is inserted into the screw holes 52, 72 through the holding plate 50, and is fixed to the receiving bracket 70, and the instrumentation pipe 1 is assembled. Then, the cradle bracket 70
