Description

  The present invention relates to a piping rack that supports pipes arranged in various plants side by side, a water treatment plant using the piping rack, and a method for manufacturing the water treatment plant.

  Conventionally, water treatment plants have been provided in a so-called “on-site installation method”. In other words, a water treatment plant is designed according to the installation site of a plant such as a factory that uses the water treatment plant (hereinafter simply referred to as “site”), and a plurality of water treatment devices constituting the water treatment plant are installed at the installation site. After installation, piping and wiring for connecting these water treatment devices, or a measurement control device for the water treatment device was attached to the water treatment device on site. In general, a water treatment plant includes a plurality of water treatment devices, and the number of pipes connecting these water treatment devices increases. Therefore, a water treatment plant usually has a piping rack that supports and fixes the pipes. Provided. As such a support, for example, a piping rack composed of a plurality of frame members, shelves, and the like is known (for example, Patent Document 1 and Patent Document 2).

  By the way, in recent years, as the quality of water treatment plants are improved, the delivery time is shortened, and the cost is reduced, water treatment plants, particularly pure water production plants, are provided in a so-called “in-house method” ( For example, Patent Document 3). In the in-house method, the water treatment plant is divided into one or a plurality of modules, and each module is manufactured in the plant provider's factory. That is, according to the in-house production method, the water treatment plant is divided into one or more modules, and piping, measurement control devices, and the like necessary for one or more water treatment devices included in each module are attached in advance. The manufactured module is transported to the site by a truck or the like and connected to other modules to complete the water treatment plant.

As described above, according to the in-house production method, since the water treatment equipment with the pipes and the like attached thereto is arranged in each module, the water treatment plant can be easily and quickly installed on the site. In addition, since the operation state of water treatment equipment in each module and the connection state with piping, etc. can be inspected in advance when the module is completed, it is easy to identify the presence or absence of defective parts and defective parts, and improve the quality of the water treatment plant There is an advantage that can be.

  By the way, in the internal work system mentioned above, each module is provided with 1 or 2 or more water treatment equipment, piping etc. connected to the said water treatment equipment, but water treatment equipment, piping, etc. which are arranged in each module The type and number vary depending on the specifications of each water treatment plant and are not necessarily uniform. For this reason, in the conventional in-house method, the piping to be arranged in each module must be individually designed for each module as in the case of the on-site installation method, which increases the time and cost required for module production. I was invited.

  In addition, each module has a piping rack that supports the piping arranged in the module. When connecting a plurality of modules on the site and assembling a water treatment plant, the piping is connected to the piping rack. A plurality of modules are connected to each other in a fixed state.

  Here, a pair of pipes arranged in different modules are fixed to a pipe rack so that they are joined in advance at a predetermined position. Conventionally, however, the joint positions of a plurality of pipes can be accurately defined. It was difficult. In addition, since the piping racks used in the past have a low degree of freedom in the position for fixing the piping, if the joint positions of the piping racks arranged in a pair of adjacent modules are shifted, the fixing position of the piping There has been a problem that the operation of changing the data becomes large.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a piping rack that can easily and accurately define the joint position of piping and reduce the time and cost required for module manufacture. Specifically, the present invention is a piping rack in which a plurality of pipes are arranged, and includes a piping rack that can easily fix and join the pipes, a water treatment plant using the piping rack, and a method for manufacturing the same. The purpose is to provide.

  The present invention is a pipe rack that supports pipes provided in various plants, particularly water treatment plants, and fixes a pipe by forming a slit around a pipe placement section that arranges a plurality of pipes on substantially the same plane. It is characterized by using a piping rack that can fix the pipe at an arbitrary position on the edge of the pipe placing portion without drilling for attaching the fixing tool. More specifically, the present invention provides the following.

  (1) A substantially rectangular pipe holding member comprising: a substantially rectangular pipe placing part for placing a plurality of pipes side by side; and a fixing part provided on an outer edge side of the pipe placing part for fixing the plurality of pipes. A gap extending along an edge of the pipe placement section is formed between the pipe placement section and the fixing section, and the fixing section includes the plurality of pipes. Each of these is fixed in the arbitrary positions along the said edge, The piping rack characterized by the above-mentioned.

  The pipe holding member is not particularly limited as long as it has a shape that expands at least two-dimensionally and has an outer edge that is substantially rectangular, and can be configured by an arbitrary member that can arrange a plurality of pipes on substantially the same plane. For example, it may be constituted by a substantially rectangular flat plate to have a substantially rectangular planar shape, or may be constituted by a rod-like member to have a substantially rectangular frame shape. The flat plate may be used alone or a plurality of flat plates may be connected to each other. In addition, the “frame shape” includes not only a hollow shape inside the frame but also a shape in which a rod-like member or the like is provided inside the frame so that the inside of the frame is striped or net-like. The pipe holding member includes a pair of faces facing each other, and hereinafter, one of the pair of faces that is in contact with the pipe is referred to as a “front surface”, and the other face is referred to as a “back surface”.

  The pipe holding member includes a pipe placing part on which the pipe is placed and a fixing part for fixing and holding the pipe with a fixture, and the pipe placing part is formed inside the pipe holding member. It is provided in the vicinity of the outer edge of the pipe placement section. The fixed part and the pipe placement part are provided on substantially the same plane, and a gap penetrating the front and back surfaces of the pipe holding member is provided between the fixed part and the pipe placement part. It is provided along.

  The gap can be formed by configuring the pipe placing part and the fixing part as separate members and connecting the fixing part to the pipe placing part in a state of being separated from the pipe placing part at a predetermined interval. Specifically, the gap can be formed by configuring the pipe placement portion with a substantially rectangular frame or a substantially rectangular flat plate, and joining a fixing portion constituted by a rod-like member at a position spaced apart from the pipe placement portion.

  Alternatively, the pipe placement part and the fixed part may be integrally formed of the same member, and a gap may be formed by cutting the pipe placement part and the fixed part at a predetermined length. Specifically, a continuous hole extending linearly by continuously cutting off a portion that enters a predetermined distance (for example, about 10 to 30 mm) from the edge of the long flat plate is used as a gap, One side portion of the continuous hole may be a pipe placement portion and the other side portion may be a fixed portion. You may provide a clearance gap 1 or 2 or more with respect to one edge of a piping placement part.

  The pipe extends from the pipe placement section to the fixed section, and the end of the pipe is inserted into the gap between the pipe placement section and the fixed section so that the edge of the pipe is connected to the pipe placement section. It is fixed in a state extending from the edge. That is, the gap provided in the pipe holding member functions as a screw hole for inserting a fixture for fixing the pipe, and the gap extends substantially continuously along the edge. In, the pipe can be easily fixed at an arbitrary position near the edge of the pipe placement portion without drilling a screw hole. In addition, since it is easy to change the fixing position of the pipe, it is possible to easily correct the position when the joint position with the pipe fixed to another pipe rack is shifted.

  Furthermore, since the gap extends substantially parallel to the edge of the pipe placement portion, it becomes easy to project the end edge of the pipe with a predetermined length with reference to the position of the gap. For this reason, it is possible to easily define a joint position for connecting a plurality of pipes arranged at substantially the same height with other pipes.

  (2) An intermediate frame comprising the pipe holding member and a column connected to the pipe holding member and extending in a direction orthogonal to the edges, and a frame member connected to the column, and the middle frame An outer frame body having a substantially rectangular parallelepiped frame shape surrounding the body, wherein the inner edge of the pipe holding member is separated from the outer frame body by a predetermined distance from the outer frame body.

And three interstitial members 115.

  The long fixing material 113 </ b> N and the short fixing material 113 </ b> M are orthogonal to each other via the support column 151 and are provided along each of the four sides of the mounting frame 112 to form the fixing portion 130. Further, the placement frame 112 and the interstices 115 form a pipe placement portion 120 having a substantially rectangular frame shape. The long fixing material 113N is substantially parallel to the long side 112N of the placement frame, and in this embodiment, the length is about 600 cm. On the other hand, the short fixing material 113M and the intermediate material 115 are substantially parallel to the short side 112M of the placement frame, and in the present embodiment, these lengths are both about 230 cm.

  In the present embodiment, the placement frame 112 is made of a steel material having a substantially L-shaped cross section (hereinafter referred to as “L-shaped steel material”) in order to increase strength. On the other hand, since the long fixing material 113N and the short fixing material 113M may be lower in strength than the mounting frame 112, in the present embodiment, the long fixing material 113N and the short fixing material 113M are configured by a flat steel material (hereinafter referred to as “plate steel material”). The members constituting the pipe holding member 110 are not limited to these steel materials. For example, when strength is required, a steel material having a substantially U-shaped cross section (hereinafter, “grooved steel”), a square material having a square cross section, or the like can be used instead of the L-shaped steel material. If a flat steel material is used and strength is required, the plate thickness may be increased as compared with the case of using a square or the like.

  Each of the long fixing material 113N and the short fixing material 113M is joined to the placement frame 112 with a gap S therebetween. FIG. 3 is a schematic diagram of the pipe placement portion 120 including the portion indicated by the symbol A in FIG. 1 and shows a state in which the short fixing material 113M is attached to the short side 112M of the placement frame by the attachment tool 140.

Shown from the side. The fixing tool 131 is a substantially U-shaped linear member, and both end edges are male threads, and the both end edges are spaced with the linear member sandwiching the pipe P placed on the surface F of the pipe holding member 110. The pipe P is fixed by inserting it into S and attaching a nut N on the back surface B side of the pipe holding member 110.

  As shown in FIGS. 2 to 4, the gap S provided in the pipe holding member 110 extends along the edge of the substantially rectangular pipe placing part 120. As described above, in the present invention, a gap is provided between the pipe placing part 120 and the fixing part 130 except for a part to which the attachment tool 140 is attached. For this reason, in the present invention, the pipe P can be fixed by inserting the screw of the fixing tool 131 into an arbitrary position along the placement frame 112 constituting the edge of the pipe placement section 120. Furthermore, since the fixing position of the pipe P once fixed can be changed simply by loosening the nut N, fine adjustment of the fixing position of the pipe P is also facilitated.

  Further, since the gap S is provided substantially parallel to the edge of the pipe placement section 120, the end of the pipe P is extended to the outside of the pipe placement section 120 with a predetermined length with respect to the position of the gap S. By letting out, the joint position of the piping P and other piping can be prescribed | regulated easily. The clearance S and the fixing part 130 may be provided along at least one of the four sides of the pipe placement part 120. However, in order to increase the degree of freedom of the joint position of the pipe P, it is preferable to provide along each of a pair of substantially parallel sides (for example, a pair of long sides 112N or a pair of short sides 112M), More preferably, it is provided along each of the four sides as in this embodiment.

  FIG. 6 is an overall perspective view of the piping rack 2 according to the second embodiment of the present invention.
