Summary of the Invention

Problem to be Solved by the Invention

[0004] However, since the waterproof fixture is located under the existing waterproof sheet, it is difficult to find the waterproof fixture, and it takes time to specify the position of the waterproof fixture from above the waterproof sheet. In addition, although it is necessary to arrange the repair fixture above the specified waterproof fixture, it takes time to perform the positioning work. As described above, there is room for improving the efficiency of conventional waterproof layer repair work.

[0005] Accordingly, an object of the present invention is to provide a waterproof layer repair tool that can improve the efficiency of waterproof layer repair work.

Means for Solving the Problem

[0006] The waterproof layer repair tool of the present invention is used in repair work to lay a new repair sheet on top of a waterproof layer in which a waterproof sheet is fixed to the upper surface of waterproof fasteners fixed to a waterproof substrate, and comprises a detection unit for detecting the waterproof fasteners from above the waterproof sheet, and a fastener placement mechanism for positioning the repair fasteners for fixing the repair sheet at a repair target position which corresponds to a position directly above the waterproof fasteners on a member located above the waterproof fasteners detected by the detection unit.

[0007] According to this invention, the detection unit can detect waterproofing fasteners beneath the waterproofing sheet, making it easier to pinpoint the location of the waterproofing fasteners. Furthermore, the fastener placement mechanism allows for the placement of repair fasteners at the detected repair target locations, thus simplifying the installation of the repair fasteners. Consequently, this enables more efficient repair work on the waterproofing layer.

[0008] In the present invention, it is preferable that the fastener placement mechanism has a guide portion for guiding the fastener for modification to the position to be modified.

[0009] With this configuration, the guide unit positions the repair fastener at the location to be repaired, making it easy for workers to position the repair fastener at the location to be repaired.

[0010] In the present invention, the fastener placement mechanism preferably has a housing section for housing the repair fastener, and the guide section preferably guides the repair fastener housed in the housing section to the position to be repaired.

[0011] With this configuration, by pre-storing the repair fasteners in the storage section, it becomes possible to identify the repair target location using the detection unit and then place the stored repair fasteners directly into place. Furthermore, since the guide unit positions the repair fasteners at the repair target location, workers can easily place the repair fasteners at the target location.

[0012] In the present invention, it is preferable that a base is provided to slidably support the detection unit.

[0013] With this configuration, after identifying the repair target location using the detection unit, the detection unit can be moved to a different location from the repair target location by sliding it on the base. As a result, it becomes easier to perform tasks such as fine-tuning the placement of repair fasteners while the waterproofing layer repair tool is in place.

[0014] In the present invention, the fastener placement mechanism preferably includes a housing section for housing the repair fasteners and a transport mechanism for transporting the repair fasteners housed in the housing section toward the repair target location.

[0015] With this configuration, by pre-storing the repair fixing device in the storage compartment, it becomes possible to identify the repair target location using the detection unit, and then use the transport mechanism to position the repair fixing device stored in the storage compartment.

[0016] In the present invention, the transport mechanism has a movable part that is slidably supported on the base and moves the repair fixing device, and it is preferable that when the movable part is slid, it slides together with the detection part and pushes the repair fixing device toward the position to be repaired.

[0017] With this configuration, after identifying the location to be repaired using the detection unit, the repair fixing device can be placed at the location to be repaired simply by the worker sliding it.

[0018] In the present invention, the transport mechanism has a guide portion that guides the repair fixing device to the repair target position, and it is preferable that the guide portion guides the repair fixing device, which has been pushed by the moving portion, to the repair target position.

[0019] With this configuration, the repair fixing device, which is pushed by the movable part, is guided to the repair target position by the guide part, making it possible to position the repair fixing device more accurately at the repair target position.

[0020] In the present invention, it is preferable that the base portion is provided with a handle portion used when gripping the base portion.

[0021] According to this configuration, an operator can more easily perform a sliding operation by gripping the handle portion.

[0022] In the present invention, it is preferable that the detection unit includes a plurality of sensors arranged at different positions, the sensors are configured to be capable of detecting the waterproof fixing tool present in a region around the sensors, and the detection unit is configured to be capable of identifying which of the plurality of sensors has detected the waterproof fixing tool.

[0023] According to this configuration, an operator can identify the direction in which the waterproof fixing tool is located by checking the position of the sensor that has detected the waterproof fixing tool among the plurality of sensors, and further, when all the sensors detect the waterproof fixing tool, can identify that the waterproof fixing tool exists near the center position of the plurality of sensors. As a result, it becomes possible to specify the position of the waterproof fixing tool with high accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, the outdoor side of the roof is referred to as "upper" or "top," and the indoor side of the roof is referred to as "lower" or "bottom."

[0026] [About the basic structure of the waterproof layer] Figure 1 shows the roof of a building before the waterproofing layer repair method of the present invention is implemented. Board-shaped insulation material 2 is laid out on top of the waterproofing base 1, and a waterproofing layer L1 is formed on top of the insulation material 2, with a waterproofing sheet 3 fixed to the upper surface of fixed waterproofing fasteners 4.

[0027] In this embodiment, the waterproofing substrate 1 is a concrete flat roof, but it is not limited to this. Any material or structure used in conventional waterproofing structures such as ALC, wood, steel, or metal folded plate roofs may be used. It may also be something other than a roof, as long as it forms the waterproofing layer L1.

[0028] Insulation material 2 is made of, for example, a urethane-based foam material and contains countless independent air cells. In addition, insulation material 2 has appropriate strength and thermal insulation properties.

[0029] [Regarding seat fasteners] Multiple waterproof fasteners 4 are arranged on the insulation material 2 at intervals from each other, and a waterproof sheet 3 is adhered and fixed to the upper surface of the waterproof fasteners 4.

[0030] The waterproof fastener 4 is, for example, made of a stainless steel disc with a diameter of about 50 to 100 mm. As shown in Figures 2 and 3, the upper surface of the waterproof fastener 4 is covered with a hot-melt adhesive layer H1 made of thermoplastic synthetic resin as an adhesive to the waterproof sheet 3.

[0031] The waterproof fastener 4 has a protruding portion 4a that extends upward. The upper surface of the protruding portion 4a is the surface (fixing surface 4b) to which the waterproof sheet 3 is fixed. The protruding portion 4a is annular in shape (see Figure 1). The fixing surface 4b is covered with the hot melt adhesive layer H1 described above.

[0032] The waterproof fastener 4 is fixed to the waterproof substrate 1 by a fixing member 8. In this embodiment, the fixing member 8 is made of a screw. The fixing member 8 is inserted through the central hole of the waterproof fastener 4 and then driven into the insulation material 2 from above. Furthermore, by screwing the fixing member 8 into the waterproof substrate 1, the fixing member 8 fixes the waterproof fastener 4 to the waterproof substrate 1.

[0033] [About waterproof sheets] The waterproof sheet 3 is constructed by forming a waterproof material, such as polyvinyl chloride resin, into a sheet.

[0034] The waterproof fastener 4 and the waterproof sheet 3 are fixed together by first placing the waterproof sheet 3 over the hot melt adhesive layer H1 of the waterproof fastener 4, and then inductively heating the waterproof fastener 4 from above the waterproof sheet 3 using an electromagnetic induction heating device (not shown), thereby melting the hot melt adhesive layer H1 and the waterproof sheet 3 with the heat and bonding the waterproof fastener 4 and the waterproof sheet 3 together.

[0035] As described above, the waterproof layer L1 also needs to be repaired as its service life expires. Figure 8 is a cross-sectional view showing the waterproof layer L2 after a waterproof layer repair method has been implemented, in which a new repair sheet 10 is laid on top of the waterproof layer L1, which has a waterproof sheet 3 fixed to the upper surface of a waterproof fastener 4 fixed on a waterproof base 1.

[0036] As shown in Figure 8, a repair fastener 11 for fixing the repair sheet 10 for waterproofing layer repair is positioned in a location that overlaps with the waterproofing fastener 4 of the waterproofing sheet 3. The waterproofing fastener 4 and the repair fastener 11 are mechanically connected by screws 12. The repair sheet 10 is fixed to the upper surface of the repair fastener 11 with hot melt adhesive layer H2 (see Figure 7), forming a new waterproofing layer L2.

[0037] The waterproofing fasteners 4 installed beneath the waterproofing sheet 3 are installed using waterproofing layer repair tools 20. The configuration of the waterproofing layer repair tools 20 is described below.

[0038] [Regarding waterproofing repair tools] As shown in Figures 4 to 6, the waterproofing layer repair tool 20 is equipped with a detection unit 21 that detects the waterproofing fasteners 4 from above the waterproofing sheet 3, and a fastener placement mechanism F for positioning repair fasteners 11 for fixing the repair sheet 10 at a repair target position which corresponds to a position directly above the waterproofing fasteners 4 on a member located above the waterproofing fasteners 4 detected by the detection unit 21 on the surface of the waterproofing layer L1.

[0039] The waterproofing layer repair tool 20 includes a base 23 that supports a detection unit 21, and the detection unit 21 is slidably supported on the base 23. The base 23 is also provided with a handle 30 used when gripping the base 23.

[0040] The detection unit 21 includes four position detection coil units 22 arranged at different locations, which serve as sensors for detecting the waterproof fasteners 4. The position detection coil units 22 are configured to detect the waterproof fasteners 4 that are present in the area surrounding the position detection coil unit 22.

[0041] By sliding the waterproofing repair tool 20 across the surface of the waterproofing layer L1, the waterproofing fasteners 4 can be detected. The worker can then identify the detected location as the repair target location where the repair fasteners 11 will be installed.

[0042] The four position detection coil units 22 are arranged around the vertical axis VL at a pitch of 90 degrees at a central angle and are configured to detect different positions within one waterproofing fixture 4.

[0043] The detection unit 21 includes an alarm device 40 that can identify which of the multiple position detection coil units 22 detected the waterproof fastener 4. In this embodiment, the alarm device 40 is provided with multiple lighting devices arranged to correspond to the arrangement of the position detection coil units 22, and the alarm is provided by the lighting of these lighting devices. Here, the alarm device 40 is not limited to lighting devices, and may also include, for example, a sound generator that provides an alarm, a display device that displays an image, etc.

[0044] For example, when the frontmost of the four position detection coil units 22 detects the waterproof fastener 4, the worker can know that the waterproof fastener 4 is located in front of the detection unit 21. When all of the position detection coil units 22 detect the waterproof fastener 4, the detection unit 21 is positioned above the waterproof fastener 4. The worker can identify this position as the location to be repaired, where the repair fastener 11 will be installed.

[0045] A groove 21a is provided in the lower part of the detection unit 21, into which the edge portion of the base portion 23 can fit. The base portion 23 is configured to be slidable with its edge portion fitted into the groove 21a.

[0046] The fastener placement mechanism F comprises a storage section 24 for housing the repair fasteners 11, and a transport mechanism T for transporting the repair fasteners 11 housed in the storage section 24 toward the repair target location.

[0047] The housing section 24 is slidably supported on the base section 23, similar to the detection section 21, and is positioned side-by-side with the detection section 21. The housing section 24 comprises a rear wall section 25 located on the side opposite to the detection section 21, and two side wall sections 26 extending from both ends of the rear wall section 25 toward the detection section 21. The repair fixing device 11 is housed in the space enclosed by the rear wall section 25 and the side wall sections 26, resting on the upper surface of the base section 23. The detection section 21-side ends of the side wall sections 26 are connected to the detection section 21.

[0048] The lower portion of the side wall 26 is provided with a groove 26a, similar to the detection unit 21, into which the edge portion of the base 23 can fit. The groove 26a of the side wall 26 is connected to the groove 21a formed in the detection unit 21. With this configuration, the housing 24 is configured to slide together with the detection unit 21 from one end to the other end of the edge portion of the base 23.

[0049] An opening 27 is formed in the base portion 23. The detection portion 21 and the housing portion 24 slide along the base portion 23, allowing the detection portion 21 to be positioned on the opening 27 in a detection state, and the housing portion 24 to be positioned on the opening 27, with the top of the opening 27 open in a mounting state.

[0050] When in detection mode, the position detection coil unit 22 is located above the opening 27 and is configured to detect the waterproofing fastener 4 through the opening 27. The worker activates the waterproofing repair tool 20 and performs a detection operation to locate the waterproofing fastener 4 installed in the waterproofing layer L1.

[0051] When the operator slides the detection unit 21 against the base 23, the rear wall 25 and side wall 26 of the housing unit 24 slide together with the detection unit 21 along the upper surface of the base 23. When the housing unit 24 is slid while the repair fixing device 11 is housed in it, the rear wall 25 pushes the repair fixing device 11 toward the opening 27. In other words, the rear wall 25 functions as a moving part 28 that pushes and moves the repair fixing device 11.

[0052] The side wall portion 26 of the housing portion 24 functions as a guide portion 29 that guides the repair fixing device 11 to the opening 27 and the position to be repaired when the detection portion 21 is slid and the repair fixing device 11 is pushed by the rear wall portion 25 (movable portion 28). The transport mechanism T is composed of the movable portion 28 and the guide portion 29.

[0053] The transport mechanism T transports the repair fasteners 11 housed in the housing section 24 toward the opening 27, and places them on the surface of the waterproof layer L1 through the opening 27. Here, the opening 27 may be configured to allow for changes in its dimensions to accommodate various types of repair fasteners 11.

[0054] The following describes the steps for repairing a waterproof layer L1, which has a waterproof sheet 3 fixed to the upper surface of a waterproof fastener 4 fixed on a waterproof substrate 1, using a waterproof layer repair tool 20.

[0055] <Insulation sheet laying steps> In the insulating sheet laying step, as shown in Figure 3, the insulating sheet 13 is laid in such a way that the plasticizer in the repair sheet 10 does not migrate to the waterproof sheet 3. After laying the insulating sheet 13, a specific step is performed. Here, the specific step may be performed after laying one insulating sheet 13, or after laying the insulating sheet 13 over the entire waterproof base 1 or a predetermined section, the specific step may be performed.

[0056] <Specific Steps> As shown in Figure 4, when locating the waterproofing fastener 4, the waterproofing layer repair tool 20 is used as a detection tool to locate the waterproofing fastener 4. The waterproofing layer repair tool 20, in the detection state, is moved over the surface of the waterproofing layer L1, that is, the surface of the insulating sheet 13, until the waterproofing fastener 4 can be detected.

[0057] When all position detection coil units 22 detect a waterproof fastener 4, that position is identified as the location to be renovated where the waterproof fastener 4 is installed.

[0058] <Placement Step> As shown in Figures 5 and 6, the repair fasteners 11 for fixing the repair sheet 10 are placed on the surface of the waterproof layer L1, that is, on the surface of the insulating sheet 13, at positions corresponding to the installation locations of the waterproof fasteners 4 identified in the specific step described above.

[0059] Specifically, the worker grasps the handle portion 30, which is provided on the base portion 23 of the waterproofing layer repair tool 20 and is used when gripping the base portion 23. In this state, the detection portion 21 and the housing portion 24 of the waterproofing layer repair tool 20 are slid to place the waterproofing layer repair tool 20 in a mounted position, and the repair fixing device 11 housed in the housing portion 24 is placed on the repair target position through the opening 27.

[0060] After placing the repair fastener 11, a connecting step is performed to connect the repair fastener 11 and the waterproofing fastener 4. At this time, when the waterproofing layer repair device 20 is in place, the opening 27 is open, allowing access to the repair fastener 11 through the opening 27. This configuration allows the worker to perform the connecting step without moving the waterproofing layer repair device 20.

[0061] <Linking Steps> As shown in Figure 7, the repair fastener 11 and the waterproofing fastener 4 are mechanically connected with screws 12. Specifically, the repair fastener 11 has a through hole 11a, and in order to mechanically connect the repair fastener 11 and the waterproofing fastener 4, holes for screw insertion are drilled in the insulating sheet 13, the waterproofing sheet 3, and the waterproofing fastener 4 with a drill or the like, corresponding to the through hole 11a of the repair fastener 11. After inserting the screws 12 through these holes and the through hole 11a, the repair fastener 11 is connected to the waterproofing fastener 4 by screwing the screws 12 into the screw insertion holes with a tool such as an impact driver. At this time, instead of screws 12, connecting means such as self-drilling screws with a drill part at the tip or rivets may be used.

[0062] The waterproofing layer repair tool 20 is returned to the detection state, and the identification step is performed. The identification step and connection step are repeated until all repair fasteners 11 are connected to the waterproofing fasteners 4. After all repair fasteners 11 are connected to the waterproofing fasteners 4, the repair sheet bonding step is performed.

[0063] <Renovation Sheet Adhesion Step> As shown in Figure 8, the repair sheet 10 is placed on the upper surface of the insulating sheet 13 and the repair fastener 11. The surface of the repair fastener 11 is covered with a hot melt adhesive layer H2, similar to the waterproof fastener 4. The repair fastener 11 is inductively heated from above the repair sheet 10 using an electromagnetic induction heating device, and the heat melts the hot melt adhesive layer H2, adhering the repair sheet 10 to the upper surface of the repair fastener 11 and forming a new waterproof layer L2.
