In the above-mentioned conventional device, a steel ball is interposed between the saddle and the gantry, but when the pipe moves upward, a gap is generated between the saddle and the pedestal that move together with the pipe. If this gap becomes larger than the diameter of the steel ball, the steel ball will fall off and the desired performance cannot be exhibited. As a result, this device cannot restrain the upward movement of the pipe, and has a problem that the movement of the pipe is limited to a place where the movement is limited to a direction other than the upward direction.
Therefore, it is an object of the present invention to provide a pipe support structure that restrains the movement of the pipe in the support direction and easily allows the movement in the direction orthogonal to the support direction to ensure the fixing and thermal displacement of the pipe. do.

In order to solve the above problems, the pipe support structure of the invention according to the present application is a pair of gripping members 11 that face each other so as to sandwich the pipe P between them and fasten both ends to each other with bolts 13 to fix the pipe P to the pipe P. , One of 12 11 is attached to the structure to support the pipe P. The pipe support structure 1 includes a mounting member 10 fixed to one of the gripping members 11, a support member 2 fixed to a gantry S on the path of the pipe P, and the mounting member 10 to be mounted to support the pipe P, and the support thereof. It is provided with a holding member that projects from the member 2 to the gripping member 11 side of the mounting member 10, sandwiches the mounting member 10 with the support member 2, and fixes the mounting member 10 so as to be movable in a direction orthogonal to the arrangement thereof. The pipe P is constrained in the support direction with respect to the gantry S of the structure, and is allowed to move in the orthogonal direction.
Low friction resistance plates 6a and 10c that slide smoothly are interposed between the mounting member 10, the support member 2, and the pressing member.
The support member 2 or the holding member is rotatably supported by the support member 2 on the contact surface of the mounting member by a rotation axis in the axial direction of the pipe P, and is parallel to the direction orthogonal to the axis of the pipe P. A plurality of rollers 8 arranged in line with each other are provided.

According to the apparatus of the invention according to the present application, the holding member restrains the movement of the pipe in the support direction of the structure and allows the movement in the direction orthogonal to the support direction, so that the fixing of the pipe and the tolerance of thermal displacement are ensured.

FIG. 3 is a cross-sectional view taken along the line III-III of FIG. 2 of the pipe support structure of FIG. It is a perspective view which omitted a part of the pipe support structure of FIG. It is an enlarged front view of a part of the pipe support structure of FIG.

Embodiments of the present invention will be described with reference to the drawings.
In FIGS. 1 to 3, the pipe support structure 1 is located on the path of the pipe P and is horizontally mounted on a gantry S made of a square pipe, an H-shaped steel material, or the like, and is raised according to the support position of the pipe P. It includes an adjusted support frame 2 and a saddle 3 that supports the pipe P on the support frame 2.

The support frame 2 includes an I-shaped steel material 4, a rectangular lower plate 5 and a support plate 6 fixed in parallel to the upper and lower flanges of the long I-shaped steel material 4, and a web of the I-shaped steel material 4 between them. It is composed of a plurality of ribs 7 to which the base end portion is fixed and extends in the orthogonal direction. Although the support plate 6 constitutes a part of the support frame 2, it may be integrated as a part of the gantry S whose height is adjusted according to the vertical position of the pipe P. Slide pads 6a, which are steel plates having low frictional resistance constituting the low frictional resistance plate, are attached to the upper surfaces of both ends in the longitudinal direction of the support plate 6. The support plate 6 is supported by a pair of rollers 8 and 8 which are holding members whose horizontal rotating shafts crossing the slide pad 6a with a gap are supported by the bracket 9.

The saddle 3 includes a mounting member 10, a first gripping member 11 fixed to the mounting member 10, and a second gripping member 12 that diagonally faces the gripping member 11 vertically and vertically and grips the pipe P between them. , A bolt / nut 13 for connecting the first and second gripping members 11 and 12. The first gripping member 11 and the second gripping member 12 are continuous with the gripping portions 11a and 12a forming a semicircular outer bulge so as to receive the half portion of the pipe P and both ends of the gripping portions 11a and 12a. It is provided with joints 11b and 12b to be fastened with bolts and nuts 13. A vibration damping device or the like for suppressing the vibration of the pipe P is connected to the first gripping member 11 as needed. The upper end of the mounting member 10 is fixed to the lower surface of the base 10a mounted on the support frame 2 and the lower surface of the first gripping member 11, and rises vertically from the base 10a so as to face each other with a space between the left and right sides. It is provided with a support leg 10b having an H-shaped cross section. The width of the base 10a in the axial direction of the pipe P is smaller than the distance between the brackets 9 and 9 of the roller 8, and the base 10a is inserted into the gap between the support plate 6 and the roller 8 of the support frame 2. As shown in FIGS. 3 and 4, a slide pad 10c, which is a steel plate having a small friction resistance and constitutes a low friction resistance plate that always overlaps with the slide pad 6a, is attached to the bottom surface of both ends of the base 10a in the longitudinal direction. ing. A slide pad 10c, which is a steel plate having a small frictional resistance and constitutes a low frictional resistance plate always located at a corresponding position of the roller 8, is attached to the upper surface of both ends of the base 10a in the longitudinal direction.

In this pipe support structure 1, the saddle 3 is fixed to the pipe P by sandwiching the pipe P between the gripping members 11 and 12 and fastening the pipe P with bolts and nuts 13, and the pipe P is supported by the gantry S. In this state, the pipe P is constrained in the vertical direction because the base 10a of the mounting member 10 is vertically sandwiched between the rollers 8 and 8 and the support plate 6 of the support frame 2. On the other hand, the pipe P can be moved in the horizontal direction within the range where the difference length range between the width in the axial direction of the pipe P and the distance between the brackets 9 and 9 and the support legs 10b between the rollers 8 and 8 are restricted. During these movements, the rollers 8 and 8 roll on the base 10a, and the base 10a moves with respect to the support plate 6 due to smooth sliding between the rollers 8 and the slide pad 10c and between the slide pads 6a and 10c. It is performed smoothly and allows the thermal displacement of the pipe P reasonably.

In the present embodiment, the pipe P is supported in the vertical direction with respect to the gantry S, but the present invention is not limited to this, and the pipe P is supported in the horizontal direction with respect to the gantry S. In this case, the configuration is appropriately changed such that the support plate 6 constituting the support frame 2, the rollers 8 constituting the holding member, the base 10a constituting the mounting member 10, etc. are arranged in the horizontal direction in the vertical direction. Needless to say, it can be applied by this.

Further, the slide pad 6a is attached to the support plate 6, but instead of the slide pad 6a, the slide pad 6a is always located at the corresponding position of the slide pad 10c and has a horizontal rotation axis that crosses the slide pad 10c with a gap below the slide pad 10c. The rollers may be supported, and even in this case, the base 10a can be smoothly moved with respect to the support plate 6.
Further, instead of the roller 8, a holding plate to which a slide pad in contact with the slide pad 10c is attached may be crossed over the base 10a, and in this case as well, the base 10a may smoothly move with respect to the support plate 6. It can be carried out.
