[0003] [Patent Document 1] JP 2024-44884 A Summary of the Invention [Problem to be solved by the invention]
[0004] Flat roofs with no slope are common in buildings and condominiums. To prevent leaks from a flat roof, waterproof sheets are attached to the roof and a sealant is applied to the joints or on cracks in the concrete. When applying a sealant to the joints of a waterproof sheet, it is necessary to seal the gaps in the joints with the sealant. Also, when applying a sealant to cracks in concrete, it is necessary to apply the sealant so that there are no gaps above the cracks.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an example of a configuration of a sealant shaping tool according to an embodiment of the present invention, viewed from an obliquely upward direction. As shown in FIG. 1, the sealant shaping tool 10 includes a gripping part 100 and a main body part 200. The main body part 200 is made of wood, plastic, or the like. The gripping part 100 is made of, for example, a "U"-shaped metal fitting, and is attached to the upper surface of the main body part 200 with a wood screw or the like. The shape of the gripping part 100 is not particularly limited, and may be made of, for example, a "T"-shaped metal fitting. The material of the gripping part 100 is not limited to metal, and may be, for example, wood. The sealant shaping tool 10 shapes the sealant applied to the application surface. The gripping part 100 is used by an operator to grip the gripping part 100 and slide the main body part 200 along the applied sealant.
[0013] Fig. 2 is a perspective view of the main body 200 as viewed obliquely from above the top surface, and Fig. 3 is a perspective view of the main body 200 as viewed obliquely from above the bottom surface. Fig. 4 is a diagram showing the width and height of the cross section of the groove at both ends as viewed from the front. As shown in Fig. 2 and Fig. 3, the main body 200 has a groove 201 on the bottom surface 200D side, which extends in the longitudinal direction and has both ends open. The main body 200 has two faces 200F, 200B that face each other parallel to the longitudinal direction, two faces 200R, 200L that face each other parallel to the lateral direction, and two faces 200U, 200R that face each other non-parallel to the height direction. The faces 200F, 200B are the front and back faces of the main body 200, the faces 200R, 200L are the right and left sides of the main body 200, and the faces 200U, 200D are the top and bottom faces of the main body 200. Although the face 200D is divided into two by the groove 201, it will be described as one face.
[0014] The width and height of a cross section at one end of the groove 201 in the longitudinal direction (the opening on the face 200F that becomes the front) are greater than the width and height of a cross section at the other end (the opening on the face 200B that becomes the back). In FIG. 4, the width LM1 and height HM1 of the cross section at one end of the groove 201 in the longitudinal direction as viewed from the face 200F that becomes the front are greater than the width LM2 and height HM2 of the cross section at the other end. By configuring the groove 201 in this way, the sealant is pressed against and adheres to the joints or cracks of the waterproof sheet, and is shaped according to the size of the cross section at the other end that becomes the exit. The worker applies (applies) the sealant linearly onto the joints or cracks of the waterproof sheet, and shapes the sealant by sliding the bottom surface of the sealant shaping tool 10 linearly. The opening on the surface 200F serves as the inlet for the sealant, and the opening on the surface 200B serves as the outlet for the sealant. Thus, the width and height of the cross section of the shaped sealant are width LM2 and height HM2. The cross sections of one end and the other end of the groove 201 in the longitudinal direction are arc-shaped, but the shape is not particularly limited and may be, for example, a rectangle or a cut polygon.
[0015] Groove 201 extends in a curved shape from one end side (the side of surface 200F) to the other end side (the side of surface 200B), and such groove 201 can be obtained by the method of manufacturing main body portion 200 shown in Figure 5. As shown in FIG. 5, a rectangular prism 20 with a cylindrical opening in the length direction is cut in half from the side in the horizontal direction to obtain two pillars 21 with semicircular grooves. Then, each pillar 21 is cut obliquely from the side to obtain two main body parts 200. As shown in FIG. 4, the obtained main body part 200 has a width LM1 and height HM1 of a cross section at one end of the longitudinal direction of the groove 201 as viewed from the face 200F, which is the front face, which is larger than the width LM2 and height HM2 of the cross section at the other end, and the groove 201 is formed to extend in a curved shape from the one end side (the face 200F side) to the other end side (the face 200B side). If the material of the rectangular prism 20 is wood, it becomes easy to cut the rectangular prism 20 and the pillars 21. In this case, the material of the main body part 200 is wood.
[0016] Groove 201 extends in a curved manner, as opposed to extending in a straight line from one end side (the side of surface 200F) to the other end side (the side of surface 200B), which has the effect described below. When groove 201 extends linearly from one end side (the side of surface 200F) to the other end side (the side of surface 200B), as shown in FIG. 6, sealing agent 30 before shaping may be subjected to force from the inclined surface of groove 201 near the entrance of main body portion 200, causing part of it to protrude from the groove. On the other hand, when groove 201 extends in a curved shape from one end side (the side of surface 200F) to the other end side (the side of surface 200B), as shown in FIG. 6, sealing agent 30 before shaping advances to a position away from the entrance of main body portion 200 and receives force from the inclined surface of groove 201, thereby preventing a part of it from protruding out of the groove.
[0017] In order to make the shaped sealant 30A linear, it is desirable to shape the sealant 30 by sliding the sealant shaping tool 10 along a guide material 40 as shown in Fig. 8. The height of the guide material 40 may be greater or less than the height of the sealant shaping tool 10. In order to slide the sealant shaping tool 10 along the guide material 40, the surface 200D that will be the bottom surface is used as the sliding surface, and at least one of the longitudinal surfaces (side surfaces) 200L, 200R of the sealant shaping tool 10 is used as the sliding surface that slides against the side surface of the guide material 40.
[0018] FIG. 8 is an explanatory diagram showing an example in which the sealant shaping tool 10 is slid along the guide material 40 with the surface 200L, which is a side surface in the longitudinal direction, serving as a sliding surface. As shown in FIG. 8, the worker dispenses (applies) the sealant 30 onto the application surface on the joints or cracks of the waterproof sheet. Next, the worker places the guide material 40 along the sealant 30, places the sealant shaping tool 10 so that the sealant 30 enters the opening provided on the surface 200F that will be the front surface of the sealant shaping tool 10, and slides the sealant shaping tool 10 along the guide material 40. As the worker slides the sealant shaping tool 10, the sealant 30 is shaped into the sealant 30A, and finally the shaped sealant 30A remains on the application surface. The width and height of the cross section of the shaped sealant 30A are width LM2 and height HM2.
[0019] The above-described embodiment is a preferred embodiment of the present invention, but the scope of the present invention is not limited to the above-described embodiment, and the present invention can be implemented in various modified forms without departing from the gist of the present invention.
[0020] When the main body 200 is produced by the production method shown in Fig. 5, the surface 200D which is the bottom surface of the main body 200 and the surface 200U which is the top surface are not parallel, and the height H2 from the surface 200D which is the bottom surface of the main body 200 to the surface 200U which is the top surface is smaller than the height H1 of one end side (surface 200F side) of the groove 201. However, as shown in Fig. 9, the main body 200 may be replaced with the main body 201, and the height from the surface 200D which is the bottom surface of the main body 201 to the surface 200U which is the top surface may be the same on one end side (surface 200F side) of the groove 201 and the other end side (surface 200B side) of the groove 201.
