Specifically, the server 10 is connected to a CAD device 30 and an administrator terminal 40 via a LAN (Local Area Network) 20. The server 10, the CAD device 30, and the manager terminal 40 are all installed in a management room, for example.

On the other hand, the reader / writer (external device) 50 and the position measuring device (external device) 60 are used by the operator in the field. The reader / writer 50 is for reading information recorded on the IC tag 70a in a non-contact manner or writing information in the IC tag 70a in a non-contact manner. The IC tag 70a is a non-contact IC chip with a built-in antenna. Note that the reader / writer 50 is prepared to be portable.
The IC tag 70a is attached to each piping sleeve to be described later. The IC tag 70a records a sleeve number (piping sleeve identification information) d1 for uniquely identifying each sleeve.

  The position measuring device 60 is a known non-contact three-dimensional measuring device using, for example, a laser or a CCD camera. The position measuring device 60 measures the installation position of the piping sleeve, which will be described later, the piping measurement gap amount d8 which will be described later, the measurement gap amount d11 for the heat insulating material which will be described later, based on each point of the obtained measurement point group. Is configured to do. Hereinafter, the server 10, the CAD device 30, and the administrator terminal 40 will be described in detail.

  First, the server 10 will be described in detail. The server 10 is for supporting the construction of a piping sleeve (hereinafter simply referred to as “sleeve”), and specifically includes a communication unit 11, a storage unit 12, and a processing unit 13 for controlling them. . The processing unit 13 is a processing device such as a CPU. The communication unit 11 is for realizing communication among the reader / writer 50, the CAD device 30, and the manager terminal 40. For example, a communication interface such as a wireless board or a LAN board corresponds to this.

The storage unit 12 is a storage device such as a memory or a hard disk. In this storage unit 12,
A sleeve list 121, a piping gap amount list 122, a heat insulating material gap amount list 123, and a hole closing related condition 124 are stored. Hereinafter, these will be described in detail in order.
The sleeve list 121 stores information related to the planned sleeve and piping. Specifically, as shown in FIG. 2, the sleeve list 121 includes a sleeve number d1 of the piping sleeve (see FIG. 1), a piping number d2, a sleeve dimension d3, a planned position d4, a piping heat transfer amount d5, and The correspondence relationship of the heat insulating material thickness d6 is stored. The pipe number d2 is identification information for specifying the pipe that penetrates the sleeve. The sleeve dimension d3 indicates the diameter (inner diameter) and length of the sleeve.
The planned position d4 means the position of the sleeve planned in advance, and as this display method, for example, each position in the three directions of the frontage, depth, and height of a building is used. Specifically, it is expressed based on a street core that is set in advance.
The pipe heat transfer amount d5 is set in advance based on design conditions such as thermal conductivity. The heat insulating material thickness d6 is also set in advance based on design conditions such as thermal conductivity.

As shown in FIG. 3, the piping gap amount list 122 includes the sleeve number d1, the required gap amount between the sleeve and the pipe (required gap amount for piping) d7, and the measurement between the sleeve and the pipe. The correspondence relationship between the gap amount (measurement gap amount for piping) d8 and the determination d9 is stored.
Both the necessary gap amount d7 and the measurement gap amount d8 indicate the degree of the gap between the outer diameter of the pipe and the inner surface of the sleeve. Among these, the required gap amount d7 means a design value determined in consideration of circumstances such as the pipe diameter.
On the other hand, the measurement gap amount d8 means an actual measurement value when the pipe is passed through the sleeve. In FIG. 3, “X1”, “X2”, “Y1”, and “Y2” are shown as the necessary gap amount d7 and the measurement gap amount d8, which will be described later.

  The determination d9 indicates whether or not the measurement gap amount d8 is appropriate, that is, whether or not the measurement gap amount d8 is the required gap amount d7. In other words, whether the measurement gap amount d8 is within the allowable range is indicated. For example, when the measurement gap amount d8 is the same as the required gap amount d7, “OK” indicating that it is within the allowable range is set in the determination d9. On the other hand, if the required gap amount d7 is not the same, the determination d9 is set to “NG” indicating that it is outside the allowable range. Note that the required gap amount d7 here means that it suffices if it is within a preset error range, and does not mean that it is always completely coincident.

As shown in FIG. 4, the insulation material gap amount list 123 includes the sleeve number d1, the required gap amount d10 between the sleeve and the insulation material, the measurement gap amount d11 between the sleeve and the insulation material, and the determination. The correspondence relationship of d12 is stored. Both the necessary gap amount d10 and the measurement gap amount d11 referred to here represent the degree of the gap between the outer diameter of the heat insulating material and the inner surface of the sleeve.
Among these, the required gap amount d10 means a design value determined in consideration of the circumstances such as thermal efficiency. On the other hand, the measurement gap amount d11 means an actual measurement value when a heat insulating material is attached to the pipe. In FIG. 4, “X3”, “X4”, “Y3”, and “Y4” are shown as the required gap amount d10 and the measurement gap amount d11, which will be described later.

The determination d12 indicates whether the measurement gap amount d11 described above is appropriate. That is, as in the case of the above-described determination d9 (see FIG. 3), whether or not the measurement gap amount d11 is the same as the necessary gap amount d10, that is, whether it is within the allowable range is shown. For example, when the measurement gap amount d11 is equal to the required gap amount d10, “OK” indicating that it is within the allowable range is set in the determination d12. Is set to “NG” indicating that it is outside the allowable range.
The purpose of the required gap amount d10 here is to the extent that it is within the preset error range.

The hole closing related condition 124 is a condition related to the hole finishing of the piping sleeve. As shown in FIG. 5, the hole closing related condition 124 corresponds to the sleeve number d1, the environmental condition d13, and the hole closing method d14. Stores relationships. Examples of the environmental condition d13 include negative pressure, positive pressure, water tightness, oil tightness, fire prevention, and outdoors.
The hole closing method d14 means a method for closing the sleeve. As the hole closing method d14, for example, there are various methods using mortar, rock wool and the like.

Here, a construction example of the sleeve is shown in FIG. FIG. 6A is a cross-sectional view of the sleeve in a state of penetrating the wall, and FIG. 6B is a view taken along the line I-I of FIG.
According to FIG. 6A, a sleeve is provided on the wall, and IC tags 70a are attached to both sides of the sleeve. Here, the IC tag 70a is attached to both sides of the sleeve because the environment such as negative pressure and the hole closing method may be different on each side, so that the operator can also confirm these differences. This is because of this.
A pipe passes through the sleeve, and the pipe is covered with a heat insulating material. Further, between the pipe and the sleeve, for example, mortar is filled and a hole is provided.

According to FIG.6 (b), the gap between the outer diameter of piping and the inner surface of a sleeve is shown as above-mentioned "X1", "X2", "Y1", and "Y2" (refer FIG. 3). . Among these, “X1” and “X2” represent gaps on the X direction side, and “Y1” and “Y2” represent gaps on the Y direction side.
Further, the gap between the outer diameter of the heat insulating material and the inner surface of the sleeve is shown as “X3”, “X4”, “Y3”, and “Y4” (see FIG. 4). Among these, “X3” and “X4” represent gaps on the X direction side, and “Y3” and “Y4” represent gaps on the Y direction side.

Returning to FIG. 1, the CAD device 30 includes an input unit 31 such as a keyboard, a display unit 32 such as a display, a communication unit 33 such as a LAN board, a storage unit 34 such as a memory, and a processing unit (CPU or the like) that controls these. 35.
The administrator terminal 40 is, for example, a personal computer, and includes an input device such as a mouse, a display device such as a computer display, a storage device such as a memory, and a processing device such as a CPU.

  Next, a processing procedure of the server 10 and the like when the operator provides the sleeve while checking the position of the sleeve on site will be described with reference to FIG. Here, a description will be given on the premise that the operator provides the sleeve at a predetermined position through on-site adjustment and the like. At this time, the operator attaches two IC tags 70a (see FIG. 6) to the sleeves, and then uses the reader / writer 50 to set the sleeve numbers set in advance to the IC tags 70a. The description will be made on the assumption that d1 is written.

In S <b> 1, first, the position measuring device 60 measures the installation position of the sleeve to be worked by the operation of the position measuring device 60 by the operator, and transmits the measurement position of the sleeve indicating the installation position to the reader / writer 50. . The measurement positions of the sleeve include positions in three directions set in advance as in the above-described planned position d4 (see FIG. 2).
In S2, the operator reads the sleeve number d1 written in the IC tag 70a in the sleeve using the reader / writer 50. Then, when the operator operates the reader / writer 50, the reader / writer 50 transmits the measurement position transmitted from the position measuring device 60 to the server 10 for each sleeve number d1. In this way, the measurement position of the sleeve to be worked is transmitted to the server 10.

  In S2, the reader / writer 50 transmits the sleeve number d1 to the server 10. For example, the position measuring device 60 as an external device directly associates the measurement position of the sleeve with the sleeve number d1, and directly You may make it transmit to the server 10. FIG.

  In S3, the processing unit 13 of the server 10 receives the transmission from the reader / writer 50 and receives the measurement position of the sleeve for each sleeve number d1. Subsequently, the processing unit 13 reads the planned position d4 corresponding to the sleeve number d1 described above from the sleeve list 121 (see FIG. 2) of the storage unit 12, and the measurement position received in S3 and the read planned position d4. Are compared (S4).

  If the two positions do not match as a result of the comparison (No in S5), the processing unit 13 transmits that fact to the reader / writer 50 (S6). On the other hand, if they match (Yes in S5), the processing unit 13 transmits that fact to the reader / writer 50 (S7). Thereby, for example, the inconsistency or coincidence is displayed on the display panel on the reader / writer 50, and the operator can confirm whether or not the sleeve is provided at the planned position d4. At this time, even if the sleeve is not in accordance with the planned position d4, the operator can take appropriate measures by confirming that fact. In this way, the operator provides the sleeve at a predetermined position.

  In S6 and S7, the processing unit 13 reads the sleeve dimension d3 corresponding to the sleeve number d1 received in S3 from the sleeve list 121 (see FIG. 2) of the storage unit 12, and the sleeve dimension d3 is also read by the reader / writer 50. You may make it transmit to. In this case, the sleeve dimension d3 is displayed on the display panel of the reader / writer 50, which enables the operator to confirm the sleeve dimension d3 on site, which is beneficial.

After that, after the operator passes the temporary pipe through the sleeve provided at a predetermined position, the processing procedure of the server 10 and the like in the case where construction is performed while confirming whether the gap amount between the sleeve and the pipe is correct or not is illustrated. 8 will be described.
In S20, first, the position measuring device 60 measures the measurement gap amount d8 (see FIG. 3) indicating the gap amount between the sleeve to be worked and the pipe by the operation of the position measuring device 60 by the operator. Transmit to the reader / writer 50. The measurement gap amount d8 includes “X1”, “X2”, “Y1”, and “Y2” (see FIG. 6).

  In S21, the operator uses the reader / writer 50 to read the sleeve number d1 written on the IC tag 70a in the sleeve. Then, by the operation of the reader / writer 50 by the operator, the reader / writer 50 associates the measurement gap amount d8 transmitted from the position measuring device 60 with the sleeve number d1 and transmits it to the server 10.

  In S21, the reader / writer 50 associates the measurement gap amount d8 and the sleeve number d1 and transmits them to the server 10. However, for example, the position measuring device 60 calculates the measurement gap amount d8 and the sleeve number d1. You may make it link and transmit to the server 10 directly.

  In S22, the processing unit 13 of the server 10 receives the transmission from the reader / writer 50 and receives the measurement gap amount d8 and the sleeve number d1 in association with each other. Subsequently, the processing unit 13 determines whether or not the received measurement gap amount d8 is within an allowable range (S23). Specifically, the processing unit 13 reads the necessary gap amount d7 corresponding to the received sleeve number d1 from the piping gap amount list 122 (see FIG. 3) in the storage unit 12, and the measurement gap amount d8 described above, The read necessary gap amount d7 is compared.

As a result of the comparison, when it is determined that the measurement gap amount d8 is not equal to the required gap amount d7, the processing unit 13 determines that the measurement gap amount d8 is not within the allowable range (No in S23). Is transmitted to the CAD device 30 (S24). As a result, the display unit 32 of the CAD device 30 displays the above-described effect, and the operator can take appropriate measures.
In this case, the processing unit 13 registers “NG” indicating the determination result of S23 in the corresponding column of determination d9 (see FIG. 3) of the piping gap amount list 122.
Although the processing unit 13 transmits the message to the CAD device 30, the processing unit 13 may transmit the message to the reader / writer 50. This is useful because the operator can confirm on the site that the measurement gap amount d8 is not within the allowable range through the display panel of the reader / writer 50.

On the other hand, when the measurement gap amount d8 is determined to be the required gap amount d7 by the above-described comparison, the processing unit 13 determines that the measurement gap amount d8 is within the allowable range (Yes in S23), and the sleeve received in S22. The environmental condition d13 and the hole closing method d14 corresponding to the number d1 are read from the hole closing related condition 124 (see FIG. 5) in the storage unit 12. Then, the processing unit 13 transmits the environmental condition d13 and the hole closing method d14 to the reader / writer 50 together with the result of the determination (the measurement gap amount d8 is within the allowable range) (S25).
As a result, the operator carrying the reader / writer 50 can confirm the result of the determination and allow the temporary piping to pass through the sleeve as scheduled to proceed with the next hole closing operation. In this case, for example, the operator can confirm the environmental condition d13 such as negative pressure and the hole closing method d14 such as mortar for each sleeve, so that the hole closing work can be performed more accurately. Can do.
In this case, the processing unit 13 registers “OK” indicating the determination result of S23 in the corresponding column of the determination d9 (see FIG. 3) of the piping gap amount list 122.

  Thereafter, the operator attaches a heat insulating material to the above-described pipe (see FIG. 6), and operates the position measuring device 60 in order to measure the gap amount between the sleeve and the heat insulating material. Then, by the operation of the position measuring device 60 by the operator, the position measuring device 60 measures the measurement gap amount d11 (see FIG. 4) indicating the gap amount between the sleeve and the heat insulating material and transmits it to the reader / writer 50. (S26). The measurement gap amount d11 includes “X3”, “X4”, “Y3”, and “Y4” (see FIG. 6).

  In S27, the operator uses the reader / writer 50 to read the sleeve number d1 written on the IC tag 70a in the sleeve. Then, by the operation of the reader / writer 50 by the operator, the reader / writer 50 associates the measurement gap amount d11 transmitted from the position measuring device 60 with the sleeve number d1 and transmits it to the server 10.

  In S27, the reader / writer 50 associates the measurement gap amount d11 and the sleeve number d1 and transmits them to the server 10. However, for example, the position measuring device 60 sets the measurement gap amount d11 and the sleeve number d1. You may make it link and transmit to the server 10 directly.

  In S28, the processing unit 13 of the server 10 receives the transmission from the reader / writer 50 and receives the measurement gap amount d11 and the sleeve number d1 in association with each other. Subsequently, the processing unit 13 determines whether or not the received measurement gap amount d11 is within an allowable range (S29). Specifically, the processing unit 13 reads the necessary gap amount d10 corresponding to the received sleeve number d1 from the heat insulating material gap amount list 123 (see FIG. 4) in the storage unit 12, and the measurement gap amount d11 described above. Then, the read necessary gap amount d10 is compared.

As a result of the comparison, for example, when it is determined that the measurement gap amount d11 is not the required gap amount d10, the processing unit 13 determines that the measurement gap amount d11 is not within the allowable range, and indicates the result. "NG" is registered in the corresponding column of the determination d12 (see FIG. 4) of the gap amount list 123 for the heat insulating material.
On the other hand, when it is determined that the required gap amount d10 is the same, the processing unit 13 determines that the measurement gap amount d8 is within the allowable range, and determines “OK” indicating the result as the determination d12 ( (See FIG. 4).

  Then, the processing unit 13 transmits such a determination result to the reader / writer 50 (S30). Thereby, it becomes possible for the operator to confirm whether the gap amount between the sleeve and the heat insulating material is correct or not on the site through the display panel of the reader / writer 50, and to facilitate smooth construction. For example, when the gap amount is within the allowable range, the heat insulating material can be applied as scheduled. On the other hand, when the gap amount is not within the allowable range, the construction method of the heat insulating material can be reviewed. Therefore, the construction work of the sleeve can be performed efficiently on site.

  The present invention is not limited to the embodiment described above. The configuration, data structure (see FIGS. 2 to 5) and processing procedure (see FIGS. 7 and 8) of the sleeve construction support system may be changed and configured without departing from the spirit of the present invention. For example, although the case where the configuration is configured using one server 10 has been described, the configuration may be such that distributed processing is performed using a plurality of computers.
