Description

The present invention relates to an arrangement member for forming an unjoined region and a method for joining a waterproof sheet.

Conventionally, as a floor portion of a roof or a veranda, as shown in FIG. 1, a house to which a heat insulating panel laying portion 30 in which a large number of heat insulating panels 1 are laid is applied is known. In the heat insulating panel laying portion 30, a large number of heat insulating panels 1 are arranged in a matrix, and for example, in the adjacent heat insulating panels, one of the heat insulating panels is butted against each other as shown in FIG. The concave portion 70 is provided on the end surface, and the other heat insulating panel 1 is provided with a convex portion 60 on the end surface to be abutted, and the concave portion 70 of one heat insulating panel 1 and the convex portion 60 of the other heat insulating panel 1 are engaged with each other. By doing so, the adjacent heat insulating panels 1 are connected to each other.

The heat insulating panel laying portion 30 constitutes a roof and a floor portion by being fixed to the purlins, purlins 91, rafters, and the like provided in the house by using the fixing screws 9C.

Further, in the heat insulating panel laying portion 30 having such a configuration, a gap may occur at the boundary portion 25 between the adjacent heat insulating panels 1 depending on the construction state. If there is a gap, rainwater or the like may enter the house through this gap and cause a leak. Therefore, it has been proposed to join (attach) the waterproof sheet 8 so as to cover this gap, that is, the boundary portion, to prevent the intrusion of rainwater or the like (see, for example, Patent Document 1).

As described above, the waterproof sheet 8 is joined to the boundary between the heat insulating panels 1. Here, as described above, since the large number of heat insulating panels 1 are arranged in a matrix, the boundary portion 25 formed between them is linear. Therefore, the waterproof sheet 8 joined to the boundary portion 25 also has a linear shape (strip shape), and the waterproof sheet 8 having such a shape is joined to the heat insulating panel so as to correspond to the boundary portion 25.

Therefore, for example, Patent Document 2 describes a waterproof sheet joining device 500 used for joining a band-shaped waterproof sheet 8 to the heat insulating panel 1 so as to cover the boundary portion 25 between the heat insulating panels 1. Such a configuration can be mentioned.

That is, in the waterproof sheet joining device 500, as shown in FIG. 10, a nozzle provided in the waterproof sheet joining device 500 is provided on the edge 81 of the waterproof sheet 8 arranged so as to cover the boundary portion 25 between the heat insulating panels 1. A liquid material containing a solvent or an adhesive is supplied from No. 5, and then, at the edge 81 of the waterproof sheet 8, the edge portion of the waterproof sheet 8 is rolled from the front side by the roller 92A provided in the waterproof sheet joining device 500. At 81, the waterproof sheet 8 and the heat insulating panel 1 are joined.

By the way, as described above, a large number of heat insulating panels 1 are arranged in a matrix, and the linear boundary portion 25 formed between them is a boundary along the X-axis direction as shown in FIG. It has a portion 25A and a boundary portion 25B along the Y-axis direction. Therefore, the waterproof sheet 8 also has the waterproof sheet 8A joined corresponding to the boundary portion 25A and the waterproof sheet 8B joined corresponding to the boundary portion 25B, and is waterproof as shown in the E portion in FIG. With the sheet 8A on the lower side and the waterproof sheet 8B on the upper side, an overlapping portion 85 is formed in which these are orthogonally overlapped with each other.

In the overlapping portion 85, a step is formed with the waterproof sheet 8A on the lower side and the waterproof sheet 8B on the upper side, and a gap is formed between the waterproof sheet 8A and the waterproof sheet 8B at this step. There is a risk that rainwater or the like may enter the house through the gap. Therefore, usually, the welding work for eliminating the gap is carried out by the operator by welding the waterproof sheet 8A and the waterproof sheet 8B at the step.

By the way, this welding work by the operator is carried out after joining the waterproof sheet 8 and the heat insulating panel 1 using the waterproof sheet joining device 500. Therefore, the waterproof sheet 8A and the waterproof sheet 8B are unintentionally joined by the waterproof sheet joining device 500 in a state where a gap is formed between the waterproof sheet 8A and the waterproof sheet 8B at the step in the overlapping portion 85. It will be. Therefore, prior to the welding work, the worker is forced to perform a peeling work for peeling the waterproof sheet 8A and the waterproof sheet 8B at the step, that is, to carry out unnecessary work. there were.

Further, such a problem is caused by an overlapping portion formed by overlapping the tip of the waterproof sheet 8A along the X-axis direction (the same direction) and the base end of the waterproof sheet 8A, as shown in the F portion in FIG. The same occurs at the step in 86.

As a result, the frame 94B constitutes a quadrangular frame body having a beam extending in the X-axis direction at the center thereof.

As shown in FIG. 10, on the frame 94B, two pairs of wheels 92B are arranged so as to face each other in the X-axis direction at the four corners thereof, and each wheel 92B rotates in the Y-axis direction. It is possible to be supported by the frame 94B. Then, by rotating each wheel 92B, the joining device 500 can travel together with the supply system 10 mounted on the second vehicle body 91B. For example, when each wheel 92B rotates in the + Y axis direction (forward direction), the joining device 500 can be advanced in the + Y axis direction. Further, when each wheel 92B rotates in the −Y axis direction (retracting direction), the joining device 500 can be retracted in the −Y axis direction. Then, when the joining device 500 advances in the + Y-axis direction and reverses in the −Y-axis direction, the opposing wheels 92B each travel on a pair of wheel traveling lines Lk along the Y-axis direction. More specifically, among the wheels 92B facing each other in the X-axis direction, the wheel 92B located on the −X-axis direction side travels on the wheel travel line Lk1, and the wheel 92B located on the + X-axis direction side runs on the wheel travel line Lk2. Run.

In the present embodiment, the first vehicle body 91A is arranged in the X-axis direction between the wheels 92B facing each other in the X-axis direction, that is, between the pair of wheel traveling lines Lk along the Y-axis direction. At this position, they are connected to the second vehicle body 91B.

Further, each of the two first vehicle bodies 91A has three pressing portions 94 arranged side by side in the Y-axis direction and a connecting plate 95 connecting the three pressing portions 94.

The two first vehicle bodies 91A, one of which is arranged on the −X axis direction side and the other on the + X axis direction side, are different from each other except that the arrangement positions are different as shown in FIGS. 10, 12, and 13, respectively. , Basically the same configuration. Therefore, the first vehicle body 91A located on the −X-axis direction side will be typically described below. In addition, one of the three is at the end of the connecting plate 95 on the + Y-axis direction, one is at the end of the connecting plate 95 on the −Y-axis direction, and one is at the center of the connecting plate 95 on the −Y-axis direction. As shown in FIGS. 10 to 13, each of the three connected pressing portions 94 has basically the same configuration except that the arrangement positions are different. Therefore, the pressing portion 94 located at the end portion on the + Y axis direction side will be typically described below.

In the first vehicle body 91A, the pressing portion 94 includes a frame 94A and a plurality of (eight in this embodiment) rollers 92A rotatably supported under the pressing portion 94.

The frame 94A has two side plates 942. The two side plates 942 are arranged in the X-axis direction and are arranged so as to face each other with a gap.

In the frame 94A, as shown in FIGS. 11 and 12, a plurality of rollers 92A are arranged between the two side plates 942. The width of each roller 92A is set to a size that can include the width of the waterproof sheet 8, and is rotatably supported by two side plates 942. Then, as each roller 92A rotates, the first vehicle body 91A travels together with the second vehicle body 91B, whereby the joining device 500 travels together with the supply system 10. For example, when each wheel 92B rotates in the + Y-axis direction, each roller 92A also rotates in the + Y-axis direction, and as a result, the joining device 500 can be advanced in the + Y-axis direction. Further, when each wheel 92B rotates in the −Y axis direction, each roller 92A also rotates in the −Y axis direction, and as a result, the joining device 500 can be retracted in the −Y axis direction. Then, when the joining device 500 moves forward in the + Y-axis direction and reverses in the −Y-axis direction, the roller 92A moves in the Y-axis direction between the pair of wheel traveling lines Lk on which the opposing wheels 92B travel. It travels along the roller traveling line Ls along the line. The position where the roller 92A travels corresponds to the edge of the waterproof sheet 8, and after the solvent Q is supplied by the supply system 10, the edge of the waterproof sheet 8 is moved by the roller 92A to the waterproof sheet 8A. By rolling from the front side, the waterproof sheet 8 and the heat insulating panel 1 can be joined.

The number of pressing portions 94 located at is nine, and the number is not limited to nine.

The connecting plate 95 is a long object extending in the Y-axis direction, is arranged along the X-axis direction, and is pressed at three locations, both ends and the center of the connecting plate 95, via the connecting member 95A. The parts 94 are connected. The connecting plate 95 is connected to the second vehicle body 91B, whereby the pressing portion 94 is fixed to the second vehicle body 91B via the connecting plate 95 and the connecting member 95A. That is, the first vehicle body 91A is fixed to the second vehicle body 91B.

The connecting member 95A has a coil-shaped (spring-shaped) shaft portion 951 that is slidably connected to the connecting plate 95 and the pressing portion 94 in the vertical direction, and the shaft portion 951 is inserted inside the coil. It has a part 952. The shaft portion 951 is connected to the connecting plate 95 and the pressing portion 94 in a state of resisting the spring force of the coil portion 952.

The connecting member 95A having such a configuration urges the pressing portion 94 with respect to the connecting plate 95 in the vertical direction (Z-axis direction) so as to be swingable in the downward direction (-Z-axis direction). (See FIGS. 11 and 12).

Therefore, since the connecting member 95A is fixed to the second vehicle body 91B, the pressing portion 94, that is, the first vehicle body 91A can swing in the vertical direction (Z-axis direction) with respect to the second vehicle body 91B. It will be urged in the direction (-Z axis direction). Therefore, when the waterproof sheet 8A is rolled by the roller 92A provided in the first vehicle body 91A and the waterproof sheet 8A and the waterproof sheet 8B are joined by rolling the waterproof sheet 8A from the front side thereof, the coil portion 952 having a different urging force is inserted into the shaft portion 951. By doing so, the magnitude of the load applied to the waterproof sheet 8A can be set to a desired magnitude.

The handle 93 is supported and fixed to a pole 96 provided so as to project upward from the middle plate 614 of the frame 94B in the second vehicle body 91B. An operator who performs the joining work of the waterproof sheet 8 grips the handle 93 and pushes the joining device 500 in the + Y axis direction to move forward, or pulls the joining device 500 in the + Y axis direction to move it backward. It can be performed.

The supply system 10 corresponds to the edge of the waterproof sheet 8, more specifically, the edge of the waterproof sheet 8 arranged so as to cover the boundary portion 25, between the waterproof sheet 8 and the heat insulating panel 1. It is a structure that supplies the solvent Q.

As described above, each unit of the supply unit 10A is individually provided with respect to the supply unit 10B, but the storage unit 2 is provided as a shared unit.

In the supply unit 10A having such a configuration, in the present embodiment, the storage unit 2, the flow path 3, the pump 6, and the force transmission unit 7 are the first vehicle body 91A and the first vehicle body 91A among the parts constituting the supply unit 10A. Of the second vehicle body 91B, the nozzle 5 is arranged on the second vehicle body 91B, and the nozzle 5 is arranged on the first vehicle body 91A. Hereinafter, each part constituting the supply part 10A will be described.

In the present embodiment, the storage unit 2 is composed of a cylindrical tank as shown in FIG. It is preferable that the tank has a ventilation hole that communicates with the outside.

Further, the storage unit 2 is fixed to a support column 943 provided so as to project upward from the frame 94B, whereby the storage unit 2 is arranged on the second vehicle body 91B.

The storage unit 2 is provided not only with the supply unit 10A but also with the supply unit 10B. As a result, in the middle of joining the waterproof sheet 8 and the heat insulating panel 1 using the joining device 500, either the supply unit 10A or the supply unit 10B, that is, the two edges of the waterproof sheet 8 along the Y-axis direction. It is possible to reliably prevent the solvent Q from being supplied to any one of the portions 81.

The solvent Q, which is supplied to the edge of the waterproof sheet 8 and is used for welding the waterproof sheet 8 and the heat insulating panel 1, is stored in the storage unit 2. The solvent Q is not particularly limited, and is, for example, ketones such as tetrahydrofuran (THF), nitrobenzene, carbon tetrachloride, pyridine, ethyl acetate, cyclohexanone, and methyl ethyl ketone (MEK), and alcohols such as toluene, methyl alcohol, and isopropyl alcohol. Classes and the like can be mentioned, and one or a combination of two or more of these can be used, and among them, tetrahydrofuran is preferable. Tetrahydrofuran has excellent volatility, and various resin materials show solubility. Therefore, it is preferable as a solvent used for welding the waterproof sheet 8 and the heat insulating panel 1.

The flow path 3 is liquidtightly connected to the bottom of the storage portion 2, and is arranged on the second vehicle body 91B in this state.

The flow path 3 can be partially or wholly formed by a metal or resin pipe that communicates with the storage unit 2 and allows the solvent Q to pass through.

In the flow path 3, in the present embodiment, a plurality of pipes are connected via a joint, and the pipes are bent or curved at one or a plurality of points in the middle of the longitudinal direction thereof, and the pump 6 And the flow rate adjusting unit 4, the storage unit 2 and the nozzle 5 are connected to each other, and a flow path for supplying the solvent Q from the storage unit 2 to the nozzle 5 is formed.

The nozzle 5 is liquidtightly connected to the tip of the flow path 3 on the opposite side of the storage portion 2, and is arranged in the first vehicle body 91A in this state.

In the present embodiment, as shown in FIG. 14, the nozzle 5 is formed of a hollow metal body having a flat shape and communicates with the flow path 3.
The nozzle 5 may be provided with a reinforcing material for reinforcing the nozzle 5.

Further, as shown in FIG. 14, the nozzle 5 opens rearward, that is, toward the −Y axis direction, and the solvent Q that has passed through the flow path 3 is discharged to the edge portion of the waterproof sheet 8. have. Then, the solvent Q discharged from the discharge port 51 is used for joining the waterproof sheet 8 and the heat insulating panel 1. The shape of the discharge port 51 is a slit shape along the X-axis direction in the configuration shown in FIG. 14, but the shape is not limited to this as long as it can be supplied to the edge portion of the waterproof sheet 8. As for the nozzle 5, the nozzle 5 located on the −X axis direction side in parallel with the XY plane protrudes toward the + X axis direction side, and the nozzle 5 located on the + X axis direction side protrudes toward the −X axis direction side. ..

Then, as shown in FIGS. 10 and 14, when the nozzle 5 discharges the solvent Q, the nozzle 5 is from one side in the width direction of the waterproof sheet 8A, that is, from the −X axis direction side to the back side of the waterproof sheet 8 ( It is inserted between the waterproof sheet 8 and the heat insulating panel 1).

The supply unit 10A has such a nozzle 5, and by discharging the solvent Q from the nozzle 5, the solvent Q is supplied to the edge portion of the waterproof sheet 8.

The number of nozzles 5 installed in the supply unit 10A is not limited to one in the present embodiment, but may be two or more, for example.

When the joining device 500 is pushed forward in the + Y-axis direction, the nozzle 5 is arranged in front of the pressing portion 94, that is, each roller 92A in the forward direction of the joining device 500. Therefore, after the solvent Q is supplied from the supply unit 10A to the edge portion 81 along the longitudinal direction of the waterproof sheet 8 via the nozzle 5, the waterproof sheet 8 and the heat insulating panel 1 are attached along the longitudinal direction of the waterproof sheet 8. At the edge portion 81, the roller 92A provided in the traveling system 9 (pressing portion 94) can roll the edge portion 81 from the front side thereof (see FIGS. 10 to 14). By this rolling compaction, the waterproof sheet 8 melted by the supply of the solvent Q and the heat insulating panel 1 are joined at the edge portion 81 of the waterproof sheet 8. As a result, the waterproof property between the waterproof sheet 8 and the heat insulating panel 1 at the edge 81 of the waterproof sheet 8 is ensured. By supplying the solvent Q to the edge 81 of the waterproof sheet 8 via the nozzle 5 using the joining device 500 as described above and rolling the waterproof sheet 8 by the roller 92A after the supply of the solvent Q. A joining step of joining the waterproof sheet 8 using the joining device 500 to the heat insulating panel 1 (floor surface) in the waterproof sheet joining method of the present invention is configured.

The flow rate adjusting unit 4 is provided in the middle of the flow path 3, and is arranged on the first vehicle body 91A in this state.

The flow rate adjusting unit 4 can be configured by, for example, a variable throttle valve. As a result, the flow rate adjusting unit 4 can steplessly adjust the flow rate of the solvent Q passing through the flow path 3 by changing the throttle opening degree. With such a flow rate adjusting unit 4, the solvent Q can be supplied from the nozzle 5 in just proportion.

The flow rate adjusting unit 4 may be configured to manually adjust the flow rate of the solvent Q, or automatically adjust the flow rate of the solvent Q based on various conditions such as the viscosity of the solvent Q. It may be configured to do so.

The pump 6 is arranged on the upstream side of the flow rate adjusting unit 4 in the middle of the flow path 3, and is arranged on the second vehicle body 91B in this state.

The pump 6 sends out the solvent Q in the flow path 3 from the storage unit 2 side toward the nozzle 5 side, and can be configured by, for example, a gear pump. As the gear pump, an external gear pump, an internal gear pump, or the like can be used, but it is preferable to use an external gear pump.

In the gear provided by the pump 6, the rotational force of the wheel 92B is transmitted via the force transmission unit 7, and the solvent Q in the flow path 3 is sent out from the storage unit 2 side toward the nozzle 5 side by this rotational force. It will be.

As the pump 6, in addition to the gear pump, various pumps such as a tube pump and a diaphragm pump can also be used.

The force transmission unit 7 is located between the pump 6 and the wheel 92BA (92B), whereby is arranged on the second vehicle body 91B, and the rotational force of the wheel 92BA is transferred to the gear provided by the pump 6. introduce. Then, the pump 6 uses this rotational force to send out the solvent Q in the flow path 3 from the storage unit 2 side toward the nozzle 5 side. As a result, since the solvent Q is discharged from the nozzle 5, the waterproof sheet 8 and the heat insulating panel 1 are in a molten state at the edge of the waterproof sheet 8.

Further, as described above, after the solvent Q is discharged, the waterproof sheet 8 is rolled by each roller 92A at the edge of the waterproof sheet 8 (see FIGS. 10 and 14). As a result, the waterproof sheet 8 and the heat insulating panel 1 are joined at the edge of the waterproof sheet 8.
After the joining work is completed, the nozzle 5 is removed from between the waterproof sheet 8 and the heat insulating panel 1.

When the solvent Q stored in the storage unit 2 can be supplied to the edge of the waterproof sheet 8 via the nozzle 5 by the siphon principle, the supply unit 10A is the pump 6 and the force transmission unit. 7 may be omitted.

By advancing the joining device 500 having the above configuration in the + X-axis direction, the waterproof sheet 8A and the heat insulating panel 1 are attached to the edge portion 81 of the waterproof sheet 8 (waterproof sheet 8A) arranged along the boundary portion 25A. In the meantime, after the solvent Q is supplied from the nozzle 5, the waterproof sheet 8A and the heat insulating panel 1 are rolled from the front side thereof by the roller 92A. As a result, the waterproof sheet 8A is joined to the heat insulating panel 1 so as to cover the boundary portion 25A along the X-axis direction.

Then, after the advancing of the joining device 500 in the + X-axis direction, the advancing in the + Y-axis direction of the joining device 500 causes waterproofing at the edge portion 81 of the waterproof sheet 8 (waterproof sheet 8B) arranged along the boundary portion 25B. After the solvent Q is supplied from the nozzle 5 between the sheet 8B and the heat insulating panel 1, the waterproof sheet 8B and the heat insulating panel 1 are compacted from the front side thereof by the roller 92A. As a result, the waterproof sheet 8B is joined to the heat insulating panel 1 so as to cover the boundary portion 25B along the Y-axis direction.

Since the joining of the waterproof sheet 8A corresponding to the boundary portion 25A and the joining of the waterproof sheet 8B corresponding to the boundary portion 25B using the joining device 500 as described above are performed in this order, E in FIG. Like the portion, an overlapping portion 85 is formed in which the waterproof sheet 8A is on the lower side and the waterproof sheet 8B is on the upper side in the middle of the waterproof sheet 8A and the middle of the waterproof sheet 8B. 1. See FIGS. 6 and 7).

In the overlapping portion 85, as shown in FIGS. 6 and 7, a step 82 having the waterproof sheet 8A on the lower side and the waterproof sheet 8B on the upper side is formed on two edges of the overlapping portion 85 along the X-axis direction. Since a gap is formed between the waterproof sheet 8A and the waterproof sheet 8B at these steps 82, rainwater or the like may enter the house through the gap. Therefore, usually, the welding work for eliminating the gap is carried out by the operator by welding the waterproof sheet 8A and the waterproof sheet 8B at the step 82.

By the way, the welding work by this operator is carried out after the joining of the waterproof sheet 8 and the heat insulating panel 1 using the waterproof sheet joining device 500 described above. Therefore, when the waterproof sheet 8 and the heat insulating panel 1 are joined using the waterproof sheet joining device 500 without any treatment, there is a gap between the waterproof sheet 8A and the waterproof sheet 8B at the step 82 of the overlapping portion 85. Is formed, the waterproof sheet 8A and the waterproof sheet 8B are unintentionally joined to each other.

The step 82 is formed at two edges of the overlapping portion 85 along the X-axis direction, and the solvent Q is supplied by the joining device 500 to the two edges 81 of the waterproof sheet 8B along the Y-axis direction. Be supplied. Therefore, an unwilling joint between the waterproof sheet 8A and the waterproof sheet 8B is formed at each of the four corners 87 of the overlapping portion 85 having a rectangular shape in a plan view. Further, in the overlapping portion 85, of the waterproof sheet 8A and the waterproof sheet 8B, the waterproof sheet 8A constitutes the second waterproof sheet located on the lower side, and the waterproof sheet 8B constitutes the first waterproof sheet located on the upper side. do.

On the other hand, in the step 82 of the overlapping portion 85, in a state where a gap is formed between the waterproof sheet 8A and the waterproof sheet 8B, the waterproof sheet 8A and the waterproof sheet 8B are unwillingly separated by the waterproof sheet joining device 500. If it is possible to prevent the waterproof sheet 8A and the waterproof sheet 8B from being joined, the peeling work between the waterproof sheet 8A and the waterproof sheet 8B at the step 82, which is performed by the operator prior to the welding work, is omitted, that is, wasteful. It is possible to omit the implementation of various work.

Therefore, in the joining of the waterproof sheet 8B corresponding to the boundary portion 25B along the Y-axis direction using the joining device 500, the step 82 of the overlapping portion 85 formed with the waterproof sheet 8A on the lower side and the waterproof sheet 8B on the upper side. In the region including the waterproof sheet 8A, more specifically, in the region 84 including the four corners 87 in the plan view of the overlapping portion 85, between the waterproof sheet 8A and the waterproof sheet 8B, as shown in FIGS. 15 to 17, not yet. The joint region forming arrangement member 201 (the unjoined region forming arrangement member of the present invention) is selectively arranged.

Here, the joining of the waterproof sheet 8B corresponding to the boundary portion 25B along the Y-axis direction is performed after the joining of the waterproof sheet 8A corresponding to the boundary portion 25A along the X-axis direction using the joining device 500. Then, in the edge portion 81 along the Y-axis direction (longitudinal direction) of the waterproof sheet 8B, the region where the waterproof sheet 8B abuts on the heat insulating panel 1 on the heat insulating panel laying portion 30 (floor surface) side is the waterproof sheet 8B. The area where the waterproof sheet 8B is in contact with the waterproof sheet 8A, that is, the overlapping portion 85 is not joined to the waterproof sheet 8B and the waterproof sheet 8A. It constitutes an area.

The arrangement member 201 for forming an unjoined region is an unjoined region in which the waterproof sheet 8B and the waterproof sheet 8A are not joined to the overlapping portion 85 at the edge portion 81 along the Y-axis direction (longitudinal direction) of the waterproof sheet 8B. The solvent Q is continuously supplied as a liquid material to the edge 81 of the waterproof sheet 8B along the Y-axis direction by advancing along the Y-axis direction of the joining device 500. At that time, the waterproof sheet 8B and the heat insulating panel laying portion 30 (floor surface) side are selectively arranged and used corresponding to the overlapping portion 85 which is the unjoined region. As described above, the joined region and the unjoined region can be reliably formed by a relatively easy operation of selectively arranging the unjoined region forming arrangement member 201 corresponding to the overlapping portion 85. The step of selectively arranging the unjoined region forming arranging member 201 corresponding to the overlapping portion 85 in advance when the joining device 500 advances along the Y-axis direction is the waterproof sheet joining method of the present invention. The placement process in is configured.

Then, after advancing along the Y-axis direction of the joining device 500, the waterproof sheet 8A and the waterproof sheet 8B are brought together at the step 82 of the overlapping portion 85 by removing the arrangement member 201 for forming the unjoined region from the overlapping portion 85. It is possible to surely prevent unintentional joining. Therefore, prior to the welding work for eliminating the gap by welding the waterproof sheet 8A and the waterproof sheet 8B at the step 82, the peeling work between the waterproof sheet 8A and the waterproof sheet 8B at the step 82 is performed by the operator. It can be omitted.

It is preferable that the unbonded region is composed of one metal plate arranged collectively. Thereby, the arrangement of the unjoined region forming arrangement member 201 (metal plate) with respect to the unjoined region can be carried out by one operation. Therefore, this arrangement work can be simplified.

As a specific example thereof, the unjoined region forming arrangement member 201 (metal plate) has a first configuration and a second configuration having a rectangular shape in a plan view, as shown in FIGS. 15 and 16. Further, as shown in FIG. 17, there is a third configuration in which the plan view shape is U-shaped, and the unjoined region forming arrangement member 201 having such a plan view shape is placed on the overlapping portion 85. In the above, by arranging between the waterproof sheet 8A and the waterproof sheet 8B, the area 84 indicated by the circle including the unjoined area of the four corners 87 of the overlapping portion 85 can be arranged collectively. Is set to.

Further, when the arrangement member 201 (metal plate) for forming an unjoined region has a rectangular shape in a plan view, it is preferable that the arrangement member 201 (metal plate) has a defective portion 210 in the central portion thereof, as shown in FIG. ..
