  FIG. 1 shows a cross-sectional view of the heat insulating waterproofing fixtures 1 and 11 according to the present invention. The fixtures 1 and 11 are composed of heads 1a and 11a and shafts 1b and 11b provided with spiral threads 1d and 11d near the tip. The heat-insulating waterproof construction fixture 1 and the heat-insulating waterproof construction fixture 11 are different in terms of the length from the head outer edges 1c, 11c to the tips of the shaft portions 1b, 11b. That is, the shorter adiabatic waterproof construction fixture 1 is used at a location where the thickness of the heat insulating material is thin, such as under water, on the waterproof construction surface, while the longer adiabatic waterproof construction fixture 11 is used. Is used at a location where the thickness of the heat insulating material such as water is thick on the waterproof construction surface.

  Convex mark lines 2 and 12 are provided at positions of a length L corresponding to the screwing depth from the head outer edges 1c and 11c to the housing on the outer periphery of the shaft portions 1b and 11b. The mark lines 2 and 12 are colored with different colors.

  The heads 1a and 11a are flat head shaped with a flat top surface and a conical bearing surface. In the present invention, the shape of the head is typically such a flat screw shape, but various types can be applied without being limited thereto. For example, a disk-like flat screw shape or a hemispherical round screw shape may be employed.

  The shaft portions 1b and 11b have a shape in which helical threads 1d and 11d are formed from the vicinity of the center to the tip direction. In the present invention, the shaft portion is not limited to the presence or absence of such a screw thread, and may be one without a screw thread represented by, for example, a driving nail.

  Insulating and waterproofing fixtures 1 and 11 according to the present invention are preferably made of iron, stainless steel, brass, copper, or an alloy thereof. In addition, synthetic resin, ceramic, or the like is adopted. It is not limited to the material.

  The mark lines 2a and 12a shown in FIG. 1 according to the present invention are the length of the shaft portion at the position of the length L corresponding to the screwing depth from the head outer edges 1c and 11c to the housing on the outer periphery of the shaft portions 1b and 11b. It is formed in a convex shape over the periphery perpendicular to the direction.

  In these mark lines 2a and 12a, those formed in a convex shape are shown, but the shape is not limited. For example, the mark lines 2a and 12a are formed in a concave shape like the mark line 2b shown in FIG. It may be. Further, as shown by a mark line 2c shown in FIG. 2B, the mark may be only applied or affixed with a coloring material such as a paint or a coloring tape without being convex or concave.

  In the present invention, the mark line is preferably formed in a convex shape or a concave shape. With such a shape, the marking line can be cut at the same time, such as when forming a screw thread, at the time of production, and at the time of waterproof construction, contaminants such as dust and mud on the surface Visibility can be easily ensured by wiping off even if adhering. Further, even when the welding solvent adheres, the mark line does not disappear. There are no restrictions on the height, depth, width, and other dimensions of the convex or concave mark lines as long as visibility can be ensured.

  Moreover, in this invention, it is preferable that a mark line is colored and the color changes with the length of the fixing tool for heat insulation waterproofing construction, respectively. By doing so, the construction worker can easily select what is instructed in the design document by looking at the color, and can reduce the selection error of the fixture.

  Further, the shape of the mark line may be a shape that is oblique to the shaft portion, as indicated by the mark line 2d in FIG. By doing in this way, the construction worker can know the extent of the screwing depth by looking at a part of the mark line, and thereby adjust the screwing depth.

  Further, the number of the mark lines 2 is not limited to one, but may be plural as shown by a mark line 2e in FIG. 2D, for example. For example, the screwing depth can be adjusted efficiently by setting three or five mark lines and setting the center line as a reference line.

  Next, an example of the waterproof construction method according to the present invention will be described with reference to FIGS.

  First, as shown in FIG. 3, various types of inclined heat insulating material 5 a and flat plate-shaped heat insulating material 5 b that are inclined in one direction are stacked on a frame 6 made of substantially flat concrete, and these are laid in parallel. Lined up, the waterproof construction surface M in which the heat insulating material 5 is inclined in a certain direction is formed.

  Here, typical examples of the frame include concrete, lightweight foam concrete (ALC), porous concrete, and the like. Materials etc. can also be applied.

  Typical examples of the heat insulating material include foamed synthetic resin such as foamed polystyrene, foamed polyethylene, and foamed phenol resin, but there are no particular restrictions on the material.

  Next, a disc-shaped joining sheet 3 for a waterproof sheet made of a resin-coated steel plate having a resin coating on the surface is disposed at each of the water bottom Ma, the center portion Mb, and the water top Mc on the waterproof construction surface M. .

  Next, for the waterproof sheet joint plate 3 arranged in the lower part Ma, a short-length insulating waterproofing fixture 1 is selected, while the waterproof part arranged in the central part Mb and the upper part Mc. For the sheet joining plate 3, a long insulating and waterproofing construction fixture 11 is selected. Here, in the heat-insulating and waterproofing fixtures 1 and 11, the mark lines 2a and 12a are formed in a convex shape, and different colors are separately applied to the convex portions. By doing so, it is only necessary to select a fixture of the color as instructed in the design document according to the construction location, so that selection errors of the fixture can be reduced.

  Next, the heat insulation waterproofing construction fixtures 1 and 11 are made to pass through the heat insulating material 5 and have their tips abutted against the surface of the housing 6. Then, the shaft portions 1b and 11b of the heat-insulating and waterproofing fixtures 1 and 11 protruding on the waterproof sheet bonding plate 3 are viewed to confirm whether or not the mark lines 2a and 12a are visible on the outer periphery. If the mark lines 2a and 12a can be visually confirmed, it is confirmed that the heat-insulating and waterproofing fixtures 1 and 11 are definitely selected as sinking deeper than an appropriate screwing depth into the housing. On the other hand, if the mark lines 2a and 12a are not visible and enter the waterproof sheet joining plate 3 side or the heat insulating material 5, they are properly selected as sinking shallower than the screwing depth into the housing 6. It is determined that it is not.

  Thus, after the screwing depth is confirmed to be appropriate in the heat insulating waterproofing construction fixtures 1 and 11, as shown in FIG. 4, the respective heat insulating waterproofing construction fixtures 1 and 11 are screwed and joined to the waterproof sheet. Hold plate 3 down. Then, the waterproof sheet 4 is laid on the waterproof construction surface, and the contact portion between the waterproof sheet joining plate 3 and the waterproof sheet 4 is joined by solvent welding or heat fusion to complete the waterproof construction.

  Thus, according to the above construction method, after penetrating the heat insulating material and abutting the tip of the shaft portion against the housing surface, whether the mark line provided there is visible on the heat insulating material surface or not. Since it is only necessary to screw the fixing tool for thermal insulation waterproofing into the housing after visual recognition, the waterproof construction is good, and the selection error of the fixing tool for thermal insulation waterproofing can be prevented.
