The present invention relates to a laser fixture measuring instrument and a laser measuring system, and more particularly to a laser measuring target fixture for measuring a connection position of a connecting part such as a pipe and the like. Laser measurement system for laser measuring target fixtures.

In large structures such as ships, factories, and bridges, long-distance piping is generally laid under the piping with flanges at both ends. In addition, in the construction of ships, the block construction is often carried out, and the hull is divided into a plurality of squares. After the blocks are manufactured, the blocks are connected and the hull is constructed. At this time, it is necessary to connect pipes between the blocks. However, the piping is not properly connected by the piping of the design, such as the manufacturing error of piping, the assembly error at the time of building a block, etc. Therefore, for example, a pipe which adjusts the length by cutting a pipe having an extra length in the field, a pipe which cuts the pipe in the field and welds the angle steel, etc., and a position where the flange of the joint is drawn on the spot is used. In the shape of the drawing tube, etc., temporary piping or drawing tools are brought to the site, and after the site is adjusted, the specific length or shape, the formal piping is manufactured at the factory, and then supplied to the site to connect the piping.

In this way, piping that needs to be adjusted at the site (hereinafter referred to as field adjustment) Tube), the correct length or shape is important. As a method of measuring the mounting position of the field adjusting pipe, for example, the method described in Patent Document 1 or Patent Document 2 has been proposed.

The measurement method described in Patent Document 1 uses a three-dimensional photogrammetry method of a digital camera and a personal computer to adhere a seal-shaped measurement target having a light-reflecting portion to a flange that constitutes a mounting position of the pipe. After the outer circumference of the bolt hole or the machine coupling portion is fitted to the surface of the offset fixture, the measurement target is captured by a digital camera. Thereby, the coordinates of the target are calculated, and the center coordinates of the bolt hole or the center coordinates of the flange are calculated, and the mounting position of the specific pipe is specified.

In the measurement method described in Patent Document 2, the position measuring device is placed on one of the flanges, and the ring pin is fitted into the bolt hole of the other flange, and the wire is taken out from the position measuring device and stuck. Stop at the ring pin, thereby measuring the length or angle of the wire, and the location of the particular flange. Moreover, the measurement data obtained by the measurement method is taken in by a personal computer and converted into tube processing data. Then, by setting the conditions of the number of bends, the bending position, the type of the tube (elbow, elbow, etc.), the amount of the mold, the amount of the liner, and the like on the tube processing data, a production specification file of the field adjustment tube is prepared.

Hereinafter, embodiments of the present invention will be described using Figs. 1 to 6 . Here, Fig. 1 is a view showing an overall configuration of an outline of a laser measuring system according to a first embodiment of the present invention. Fig. 2 is a view showing a target jig for a measuring instrument shown in Fig. 1, Fig. 2A is a plan view showing a mounted state, and Fig. 2B is a side view showing a mounted state. 3 is a view showing a target jig for laser measurement according to the first embodiment of the present invention, and FIG. 3A is a partial cross-sectional view, FIG. 3B is a front view, and FIG. 3C is a first modification. The 3D diagram shows a second modification.

As shown in Fig. 1, the laser measuring system 1 according to the first embodiment of the present invention measures the first flange 11 and the second flange 12 to which the borrowing pipe is connected by receiving the reflected light of the laser light. The laser measuring system 1 of the position has a fixture 2 for measuring the sensor, the one end portion 2a and the intermediate portion 2b are fixed to the first flange 11, and the other end portion 2c extends from the first flange 11 to the outside. The laser measuring target fixture 3 is fixed to the second flange 12 and constitutes a reflector; the laser measuring device 4 is fixed to the other end portion 2c of the measuring fixture 2, and The laser light is received by the laser light, and the distance to the target fixture 3 for the laser measurement is measured; and the calculation means 5 is based on the output data of the laser measuring device 4, the shape of the fixed fixture 2 for the measuring device, and the laser The shape of the measuring device 4 and the shape of the laser measuring target fixture 3 are used to calculate the positions of the first flange 11 and the second flange 12; the laser measuring target fixture 3 has: a pedestal 31 of the flange 12; a spherical body 32 having a surface 32a capable of reflecting laser light and protruding at a portion of the surface fixed to the pedestal 31; and a fixing means 33 for pedestal 31 is fixed to the second flange 12.

The first flange 11 and the second flange 12 are, for example, a fitting portion that is disposed in a block adjacent to a large structure such as a ship or a factory. The first flange 11 is disposed, for example, on the floor surface 100 of the first square BL1 upward, and the second flange 12 is disposed on the wall surface 200 of the second square BL2, for example, downward. The first block BL1 and the second block BL2 are individually attached to each other and assembled, and then connected to each other by welding or the like. Then, the pipes connecting the first block BL1 and the second block BL2 are connected to the first flange 11 and the second flange 12. This piping is a piping that absorbs manufacturing errors or sets errors, and is a so-called field adjustment pipe. Therefore, the first block BL1 and the second block BL2 are connected, and the first After the positions of the flange 11 and the second flange 12 are determined, the positions of the first flange 11 and the second flange 12 are measured, and an on-site adjustment pipe is produced. This embodiment is suitable for measuring the positions of the first flange 11 and the second flange 12.

As shown in FIGS. 2A and 2B, the measuring fixture 2 has a plate-like member 21 which is formed to be longer than the diameter of the first flange 11 and which is fixed to the end portion 2a. The hole 22; the jig fixing long hole 23 formed in the intermediate portion 2b; the measuring device fixing hole 24 formed in the other end portion 2c; the jig fixing bolt 25 is inserted into the jig fixing hole and the 1 flange 11 and jig fixing long hole 23 and first flange 11; and jig fixing nut 26 are screwed to the jig fixing bolt 25, and have a tap that bites into the first flange 11. Face 26a.

Further, the plate-like member 21 is made of, for example, an aluminum alloy material, and the jig fixing bolt 25 and the jig fixing nut 26 are made of, for example, a stainless steel material. By the combination of the materials, it is possible to suppress the wear or cutting of the member while increasing the locking force.

By forming the plate-like member 21 longer than the diameter of the first flange 11, the laser measuring device 4 can be disposed at a position eccentric from the first flange 11. Further, by changing the fixing position of the plate member 21, the laser measuring device 4 can be disposed at any position on the outer circumference of the first flange 11. Therefore, even if the obstacle is located between the first flange 11 and the second flange 12, the laser measuring device 4 can be disposed so as to receive the light from the laser light while avoiding the obstacle.

In addition, the plate-like member 21 can also be made to cope with the change in the diameter of the first flange 11, for example, a plurality of lengths are prepared in advance as large, medium, and small. On the other hand, the plate-like member 21 of a desired length can be selected in accordance with the environment of the work site or the like.

The jig fixing long hole 23 is formed in the intermediate portion 2b of the plate member 21 along the longitudinal direction. By forming the jig fixing long hole 23, even if the size of the diameter of the first flange 11 is changed, it is easy to cope with, and the measuring fixture 2 can be fixed to the first flange 11. In the state in which the plurality of bolt holes 11a are formed in the first flange 11, the jig fixing bolts 22 and the jig fixing long holes 23 are inserted into the bolt holes 11a of the arbitrarily selected two places, and the jig fixing bolts are inserted. 25. The pair of bolt holes 11a for fixing may also be located on a diagonal line or adjacent to each other.

The gauge fixing hole 24 is a through hole into which the anchor bolt 4a that can be coupled to the lower end portion of the laser measuring device 4 is inserted. The nut 4b and the anchor bolt 4a are screwed and locked from the back surface of the plate member 21, whereby the laser measuring device 4 is fixed to the plate member 21. In FIG. 2A, the concave portion 24a disposed on the outer circumference of the measuring instrument fixing hole 24 is formed to be engageable with a convex portion (not shown) formed at the lower end portion of the laser measuring device 4, thereby contributing to Positioning of the laser measuring device 4.

The jig fixing bolt 25 is inserted into the jig fixing hole 22 and the jig fixing long hole 23 of the plate-like member 21 disposed on the upper surface of the first flange 11, and is inserted into the bolt hole 11a of the first flange 11. . Then, the jig fixing nut 26 is screwed and locked from the back surface of the first flange 11. In this manner, by connecting the jig fixing nut 26 from the back surface of the first flange 11, the locking force can be improved.

The fixture fixing nut 26 has a conical surface on the side of the nut, and the conical surface The tapered surface 26a is formed. When the jig surface 26a is formed and the jig fixing nut 26 is screwed to the jig fixing bolt 25, the tip end of the jig fixing nut 26 enters the bolt hole 11a, and the first convex is bitten by the wedge effect. The rim 11 can firmly fix the jig fixing bolt 25, and the center of the jig fixing bolt 25 can be easily aligned with the center of the bolt hole 11a.

In the laser measuring target fixture 3, when the position of the object (for example, the second flange 12) is measured by irradiating the laser beam and receiving the reflected light, the laser beam disposed on the reflector of the object is formed. The measuring fixture is used for measurement. The target fixture 3 for laser measurement has a pedestal 31, a sphere 32, and a fixing means 33 as shown in FIG. 3A.

The pedestal 31 has a plate-like member having a larger area than the bolt hole 12a formed in the second flange 12. Here, as shown in FIG. 3B, the pedestal 31 has a disk shape, but is not limited to this shape, and may be polygonal. Further, the target fixture 3 for laser measurement applies a process of absorbing laser light or scattering the surface 31a of the pedestal 31 on the side of the fixed spherical body 32. The processing may be a process of forming the unevenness or the groove on the surface 31a, a process of coloring black or gray, a process of forming a film or a coating, or a process of attaching a cloth member such as felt. By applying such processing to the surface 31a, the laser light reflected from the pedestal 31 can be reduced or the intensity can be weakened, and erroneous detection of the spherical body 32 of the system can be suppressed.

The sphere 32 is made of, for example, a metal ball such as an iron ball. However, the spherical body 32 is not limited to a metal as long as it is a material that easily reflects laser light, and a coating that enhances reflection can be applied to the surface 32a. The ball 32 is fixed to the center portion of the pedestal 31 by spot welding or the like. Also, because the surface 32a of the ball 32 is fixed Since a part of the laser beam protrudes from the pedestal 31, the laser light that is incident on the laser measuring target fixture 3 is efficiently reflected on the surface 32a of the spherical body 32.

The intensity of the reflected light reflected by the surface 32a of the sphere 32 is maximized at the measuring point P on the straight line passing through the center point Ct of the sphere 32. Since the laser light that is off center point Ct is not vertically reflected with respect to the incident angle, the intensity of the reflected light measured by the laser sensor 41 is lowered. In contrast, since the laser light incident on the straight line passing through the center point Ct of the sphere 32 is vertically reflected with respect to the incident angle, the intensity of the reflected light measured by the laser sensor 41 becomes maximum. Therefore, the distance L between the laser sensor 41 and the sphere 32 (i.e., the coordinate of the measurement point P) can be easily calculated from the flight time of the laser light.

The fixing means 33 includes an anchor bolt 33a that is erected on the back surface of the pedestal 31, and a nut 33c that is an anchor bolt that is inserted into a through hole (bolt hole 12a) formed in the object (second flange 12). 33a is screwed and has a tapered surface 33b that bites into the through hole (bolt hole 12a). The anchor bolts 33a may be welded to the back surface of the pedestal 31 or may be fixed by screwing.

The nut 33c has a conical surface on its side surface, and the conical surface constitutes a conical surface 33b. When the nut 33c is screwed into the anchor bolt 33a by forming the tapered surface 33b, the front end of the nut 33c enters the bolt hole 12a, and the second flange 12 is bitten by the wedge effect, and the laser amount can be firmly fixed. The target jig 3 is measured, and the center of the target jig 3 for laser measurement can be easily aligned with the center of the bolt hole 12a. Further, it is also possible to screw the quick bolt 33d from the nut 33c to suppress the falling of the nut 33c.

Further, the fixing means 33 may have a magnet 33e disposed on the back surface of the pedestal 31 as shown in FIG. 3C. The second flange 12 is like a steel material. In the case where the material of the magnet can be sucked, the target fixture 3 for laser measurement can be fixed to an object such as the second flange 12 by the magnet 33e. The magnet 33e may be a permanent magnet or an electromagnet that can switch ON/OFF of the suction force. By forming the fixing means 33 by the magnet 33e, the laser measuring target fixture 3 can be easily placed on a structure having no flange, top surface, wall surface, floor surface, equipment, or the like without the bolt hole 12a. surface.

Further, as shown in FIG. 3D, a protruding portion 33f that can be fitted to the bolt hole 12a or the like may be provided. By forming the protruding portion 33f, the positioning of the target fixture 3 for laser measurement can be easily performed.

The laser measuring device 4 is a machine that scans laser light within a range including the laser measuring target fixture 3 and measures the distance of the position at which the maximum reflected light intensity is obtained. Specifically, the laser measuring device 4 has a laser sensor 41 that can receive light from the laser beam, a body portion 42 that supports the laser sensor 41 to be rotatable, and a lower end portion that is disposed at the lower end of the body portion 42. Turntable 43.

The laser sensor 41 is configured to be rotatable about a drive shaft by a drive motor (not shown) disposed in the main body portion 42. The main body portion 42 is disposed on the turntable 43 and is configured to be rotatable in a state in which the turntable 43 is fixed to the measuring fixture 2 for measuring. Further, the signal processing unit 42a that processes the projection of the laser light, the scan of the laser light, the calculation of the distance, and the like is disposed in the main body unit 42. The main body portion 42 may be connected to the turntable 43 via a drive motor (not shown), or may be connected to the turntable 43 so as to be manually rotatable.

The signal processing unit 42a measures the light projection timing of the laser light and the light receiving timing of the reflected light, calculates the flight distance (reciprocation distance) from the flight time of the laser light, and calculates the distance from the laser sensor 41 to the object. Again, the signal The processing unit 42a measures the intensity of the reflected light, detects the maximum value within the predetermined measurement time, and outputs the distance of the object at the time of the maximum value as the target from the laser sensor 41 to the laser measurement. The distance of the target fixture 3. Further, the distance calculation system may detect the maximum value of the received light intensity, or may calculate the distance in advance and select the distance at which the received light intensity becomes maximum.

Further, the signal processing unit 42a may be configured to control a drive motor that rotates the laser sensor 41 and a drive motor that rotates the main body portion 42 on the turntable 43 to scan the laser light within a fixed range. . Further, it is also possible to manually perform the laser measuring device 4 when the laser measuring target fixture 3 is included in the scanning range of the laser light.

The above-described laser measuring device 4 can be manufactured by combining a relatively small electronic component, a driving motor, or the like, and can be made smaller and lighter than a metal wire measuring a physical distance. For example, the conventional metal wire measuring device has a weight of about 25 kg, but by using the laser measuring device 4, the weight can be reduced to 2 to 3 kg or less.

The calculation means 5 is composed of, for example, a CPU (Central Processing Unit), a memory device such as a RAM, a ROM, a hard disk, an input device such as a keyboard, and an output device such as a display, and is constituted by a so-called personal computer or the like. The calculation means 5 is electrically connected to the signal processing unit 42a of the laser measuring device 4 as shown in Fig. 1, and is configured to be used from the laser sensor 41 to the laser measuring target fixture. The distance of 3 is received as an output signal.

Further, in the memory device of the calculation means 5, the shape of the first flange 11 is memorized in advance (for example, the radius Rf1 and the height H1 of the first flange 11 and the snail The position of the bolt hole 11a and the diameter thereof, and the shape of the fixture fixture 2 (for example, the center distance L2 between the fixture fixing hole 22 and the gauge fixing hole 24, the thickness D2 of the plate member 21, etc.) And the shape of the laser measuring device 4 (for example, the height H4 of the main body portion 42 and the rotating table 43, the distance L4 between the main body portion 42 and the laser sensor 41, etc.). The calculation means 5 calculates geometrically based on these materials, whereby the position of the flange surface of the first flange 11, the position of the center line Mf1 of the first flange 11, the position of the bolt hole 11a, and the like can be specified.

Further, as shown in FIG. 3A, the memory device of the calculation means 5 stores in advance the shape of the second flange 12 (for example, the radius Rf of the second flange 12, the position and diameter of the bolt hole 12a, etc.), and the laser. The shape of the target fixture 32 (for example, the radius Rt of the sphere 32, the height Ht from the back surface of the pedestal 31 to the center point Ct of the sphere 32) is measured. Therefore, the calculation means 5 can easily calculate the bolt hole 12a on the second flange 12 by geometric calculation as long as the target gauge 3 for laser measurement is fixed to coincide with the center line Mb of the bolt hole 12a. The position of the center point Q (XYZ coordinates).

Further, as shown in Fig. 1, the laser measuring target fixture 3 is fixed to at least three positions of the second flange 12 (for example, the bolt holes 12a), and the calculation means 5 calculates the arrangement of the laser amount. The coordinates (XYZ coordinates) at the position of the target jig 3 are measured, and the surface and the center position (the position of the center line Mf2) of the second flange 12 are specified. By arranging the laser measuring target fixture 3 at at least three positions of the object, the surface of the specific object can be easily made.

The calculation means 5 is based on the output of the laser measuring device 4 (the distance L from the laser sensor 41 to the laser measuring target fixture 3) and the shape of the memory device The surface information and the center position of the first flange 11 and the second flange 12 are accurately specified.

Further, the calculation means 5 may be configured to set the shape of the pipe connecting the first flange 11 and the second flange 12 from the position of the first flange 11 and the second flange 12 to be specified. For example, the calculation means 5 is a three-dimensional model of the structure (the first square BL1 and the second square BL2) including the first flange 11 and the second flange 12, and the first flange 11 and the second flange 12 are taken in. The position is plotted, and the length and shape of the pipe are calculated in such a manner as to prevent the pipe from interfering with other structures. In the display of 3D models and the production of tube drawings, software such as 3D-CAD or 3D VIEWER is used.

Further, in the tube drawing, the alignment mark used for positioning the pipe 6 to be manufactured may be recorded in advance. This is because when the pipe 6 is attached to the work site, if the direction of the pipe 6 is changed, the end portion of the pipe 6 may be disposed at a position close to the flange different from the flange to be connected, and the connection position may be mistaken.

Here, Fig. 4 is a side view showing a pipe obtained by the calculation means shown in Fig. 1, Fig. 4A showing the elbow, Fig. 4B showing the zigzag tube, and Fig. 4C showing the elbow. From the positions of the first flange 11 and the second flange 12 and the positional relationship of other structures, as shown in Figs. 4A to 4C, the pipe 6 (field adjustment pipe) is selected, for example, from an elbow or a zigzag pipe. And bending the tubular shape, and setting conditions such as a bending position, a bending angle, and a length of each part. In addition, the shape of the piping 6 shown in the figure is only an example, and is not limited to the shape shown.

Here, Fig. 5 is a view showing an overall configuration of an outline of a laser measuring system according to a second embodiment of the present invention. In addition, regarding the one shown in Figure 1 The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will not be repeated.

The laser measurement system 1 of the second embodiment shown in Fig. 5 connects the calculation means 5 to an electric communication line 7 such as a network. The communication line 7 is a distributed IP network constructed by interconnecting various communication lines (a public line, a dedicated line, and a wireless communication network such as a telephone line, an ISDN line, an ADSL line, etc.) using a communication protocol TCP/IP. The IP network also includes a LAN such as an intranet (intranet) such as 10BASE-T or 100BASE-TX or a home network.

In the communication line 7, in addition to the calculation means 5, a server 71 is connected, which memorizes the three-dimensional data required for displaying the three-dimensional model, and can transmit and receive the display of the three-dimensional model or the tube drawing to the calculation means 5. The materials needed for the production. The connection between the calculation means 5 and the server 71 may be wired or wireless. The calculation means 5 is preferably a portable terminal that can be brought to the site of the measurement field adjustment tube, and uses a notebook PC, a tablet PC, a smart phone, or the like.

Further, it is also possible to make the calculation means 5 cloud-capable, and it is possible to use the three-dimensional model display or the tube to create the software and materials required for the creation of the image via the communication line 7 (the first flange 11, the second flange 12, the amount) The shape of the jig 2 is fixed for the detector, etc.).

In a large structure such as a ship, since the moving distance is long and the number of on-site adjustment pipes is also large (hundreds to thousands), the calculation means can be realized by using the calculation means 5 connectable to the electric communication line 7. 5 Lightweight and miniaturized, and can reduce the burden on the operator. Also, in the electric communication line 7, By connecting a plurality of calculation means 5 or server 71, it is also possible to perform work at the same time. Further, the output data of the laser measuring device 4 stored in the calculating means 5 is transmitted to the servo 71 and stored therein, whereby the burden on the calculating means 5 can be further reduced.

Further, it is also possible to form a factory terminal 72 that is connected to the factory that manufactures the piping 6 in the electric communication line 7. The calculation means 5 and the factory terminal 72 are connected by the electric communication line 7, whereby the pipe production diagram created by the calculation means 5 can be easily transferred to the factory terminal 72, and the labor time or the conveyance pipe production can be omitted. The labor time of the drawing can shorten the construction period of the preparation pipe 6.

According to the laser measuring target fixture 3 and the laser measuring system 1 according to the above embodiment, as the measuring means, the laser measuring is selected, and the spherical body 32 reflecting the laser light is arranged in the laser measuring By using the target jig 3, the position (distance) of the target jig 3 for laser measurement can be accurately measured, and the machine required for the laser measurement can be miniaturized and lightened.

Further, the measuring fixture 2 is fixed to the first flange 11, the laser measuring target fixture 3 is fixed to the second flange 12, and the laser measuring device 4 is fixed to the measuring device. The jig 2 is only a switch that is supplied to the laser measuring device 4, and can receive the light from the laser beam, so that the position of the object (for example, the second flange 12) can be specified, and the working time can be shortened. For example, in the conventional metal wire measurement, after fixing the jig or the measuring instrument, it is necessary to take out the metal wires of the respective holes of the plurality of bolt holes 12a of the second flange 12 and perform physical measurement one by one. The working time required for the measurement of the field adjustment tube is long (for example, about several tens of minutes), but according to the present embodiment, the working time can be shortened to about several minutes (for example, about 5 minutes).

Moreover, by making the laser measuring device 4 compact and lightweight, it can be easily handled and can be easily mounted on a high place or a top. Here, Fig. 6 is a view showing a mounting position of the laser measuring instrument and the laser measuring target jig shown in Fig. 1, and Fig. 6A shows a first modification, and Fig. 6B shows a second Modification. For convenience of explanation, the diagram of the calculation means 5 is omitted in each figure. The same components as those in the first embodiment shown in Fig. 1 are denoted by the same reference numerals, and the description thereof will not be repeated.

The first modification shown in FIG. 6A shows a case where the second flange 12 is disposed at the distal end of the pipe that extends perpendicularly to the wall surface 200 of the second block BL2. In this case, as in the first embodiment shown in FIG. 1, the laser measuring device 4 is fixed to the first flange 11 via the measuring fixture 2, and the laser measuring target is used. After the bolt hole 12a is fixed to the second flange 12, the laser measurement is performed. In the present embodiment (including the modified example), since the laser measurement is employed, as shown in FIG. 6A, even if the first flange 11 and the second flange 12 are disposed in a substantially vertical arrangement relationship, Laser light can be easily measured by irradiating the laser light to the target fixture 3 for laser measurement.

Further, even in the case where the second flange 12 is located directly above the first flange 11, in the present embodiment (including the modified example), since the laser measuring device 4 is fixed via the measuring fixture 2, the laser measuring device 4 is fixed. The position of the laser measuring device 4 can be shifted from the center position of the first flange 11, and the laser measuring device 4 can be easily disposed at a position where the laser beam can be irradiated to the laser measuring target fixture 3. .

The second modification shown in FIG. 6B shows that the first square BL1 has the wall surface 101 and the top portion 102, and the first flange 11 is disposed to hang from the top portion 102. The front end of the pipe extending straight, the second square BL2 has the floor surface 201, and the second flange 12 is disposed at the front end of the pipe extending upward from the floor surface 201. In this manner, even if the first flange 11 is disposed at the top of the top portion 102 or the wall surface 101, the laser measuring device 4 or the measuring fixture 2 for measuring the measuring device 2 can be easily reduced in size or weight, so that it can be easily passed. The measuring fixture 2 fixes the laser measuring device 4 to the first flange 11 by the fixing jig 2 . Further, the target fixture 3 for laser measurement is fixed to the second flange 12.

For example, in the case where there is no space for fixing the laser measuring device 4 to the flange of the floor surface or the lower side (here, the second flange 12), the laser measuring device 4 is fixed to the top or the height. The side flange (here, the first flange 11) is preferred. Further, in the embodiment shown in Fig. 1 or Fig. 6A, a flange in which the first flange 11 and the second flange 12 are interchanged and the laser measuring device 4 is fixed to the high side may be used.

The present invention is not limited to the above-described embodiments, and can be applied to large structures such as factories, bridges, railway vehicles, buildings, and the like other than ships, and can also be applied to connecting parts other than piping, and can be applied to the same square or It is a matter of course that various modifications can be made without departing from the spirit and scope of the invention.
