  Hereinafter, the best mode for carrying out the weir plate and finishing material according to the present invention will be described.

  FIG. 1 is a perspective view showing a first example of the weir plate and finishing material according to the present invention, FIG. 2 is a partially enlarged perspective view showing the layer structure of the weir plate and finishing material of this example, and FIG. 3 is this example. It is a partial expanded sectional view which shows the layer structure of this dam plate and finishing material.

  The dam plate / finishing material 1 of this example is used as a mold for forming an uneven portion when constructing an uneven portion of concrete provided on a waterproof layer on the roof of a building, and its shape is The plate-like body has a size corresponding to the outer shape of the uneven portion to be molded.

  The dam plate / finishing material 1 is provided with a net material 3 on the surface of a dam plate / finishing material main body 2 formed of an elastic material, and at least on the surface of the dam plate / finishing material main body 2 provided with the net material 3. The resin mortar layer 4 is laminated on the portion exposed from the concrete to be placed.

  As the elastic material forming the barrier plate / finishing material body 2, a foam of synthetic resin such as foamed polyethylene or polystyrene is used, but is not limited thereto.

  Moreover, as the net material 3 provided on the surface of the dam plate / finishing material body 2 formed of an elastic material, for example, a glass cloth mesh, a glass fiber mesh, an alkali-resistant glass fiber mesh, an aramid fiber mesh, a carbon fiber mesh, A nylon mesh, a vinylon mesh, a polypropylene mesh, etc. are mentioned. The net member 3 is stretched by being fixed to the surface of the main body 2 of the barrier plate and finishing material, but the fixing means is not particularly limited, and it is stretched to such an extent that it does not easily fall off. That's fine.

  The resin mortar layer 4 laminated on the surface of the barrier plate / finishing material body 2 provided with the net material 3 contains, for example, cement and resin emulsion as essential components. Examples of the resin emulsion include an acrylic resin emulsion made of an acrylic resin such as an acrylic resin and an acrylic silicone resin. The cement is not particularly limited as long as it is a known cement material in the technical field related to resin mortar, and examples thereof include Portland cement and alumina cement. These can be used alone or in combination of two or more. .

  Moreover, in this example, as shown in FIGS. 1 and 2, the net member 3 has an end portion 3 a that is free of any length from the end portion of the resin mortar layer 4 to the outside of the resin mortar layer 4. It protrudes.

  According to the dam plate / finishing material 1 configured as described above, the dam plate / finishing material main body 2 is formed of an elastic material, and the net material 3 is provided on the surface of the dam plate / finishing material main body 2. Since the resin mortar layer 4 is laminated on the surface of the main body 2 of the weir plate / finishing material 2 provided with 3, the weir plate / finishing material 1 has sufficient strength as a mold for molding the uneven portion of the concrete.

  And when constructing a concrete rugged portion on the waterproof layer when finishing the waterproof layer holding concrete on the roof of the building, on the waterproof layer stacked on the roof slab, depending on the concrete rugged portion to be built By arranging the weir plate / finishing material 1 and fixing the weir plate / finishing material 1 to the waterproof layer with an adhesive or the like, it is possible to construct the form of the uneven portion.

  And, after placing the waterproof layer pressing concrete and forming the concavo-convex portion, the barrier plate / finishing material 1 can be left as it is as the wall of the concavo-convex portion without being removed. There is no need to remove the barrier plate / finishing material 1 for constructing the formwork.

  Moreover, since the weir plate and finishing material body 2 is formed of an elastic material, it serves as a joint that absorbs the expansion and contraction of the concrete, and the periphery of the uneven portion that has been conventionally performed as a separate work from the formation of the uneven portion. There is no work to separately arrange joint materials to absorb the expansion and contraction of the waterproof layer holding concrete.

  Moreover, in this example, since the end 3a of the net member 3 protrudes from the end of the resin mortar layer 4 to the outside of the resin mortar layer 4 in an arbitrary length-free state, the net member 3 is laminated on the roof slab. When the weir plate / finishing material 1 is placed on the waterproof layer thus formed to form a concavo-convex portion, and when the waterproof layer holding concrete is placed, the resin mortar layer 4 starts from the end of the resin mortar layer 4. The end portion 3a of the net member 3 projecting outside is buried in the waterproofing layer pressing concrete and functions as an anchor.

  Next, a usage example of the barrier plate / finishing material 1 configured as described above will be described with reference to FIG. Drawing 4 is an explanatory view showing the example of use in the case of constructing equipment installation foundation concrete on the waterproof layer of the roof of a building.

  First, a fixing member 8 having a pin 7 for fixing a weir plate / finishing material 1 serving as a formwork at a position where equipment installation basic concrete is constructed is attached to a waterproof layer 6 laminated on a roof slab 5 with an adhesive. Secure with.

  Next, the dam plate / finishing material 1 is stabbed into the pin 7 of the fixing member 8, and the dam plate / finishing material 1 having a height from the waterproof layer to the upper end of the facility-installed foundation concrete is arranged on the waterproof layer 6 and constructed. The formwork 9 of the foundation concrete to be installed is constructed.

  Thereafter, the waterproof layer pressing concrete 10 is placed on the waterproof layer 6 to a predetermined height outside the mold 9 and into the mold 9 up to the height of the mold 9. In this way, the facility-installed foundation concrete 11 is constructed on the rooftop.

  FIG. 5 is a perspective view showing a second example of the weir plate and finishing material according to the present invention. Note that portions corresponding to those of the first example illustrated in FIGS. 1 to 3 described above are denoted by the same reference numerals.

  As in the first example, the barrier plate / finishing material 1 of the present example is provided with a net member 3 on the surface of the main body 2 of the barrier plate / finishing material body 2 formed of an elastic material, A resin mortar layer 4 is laminated on at least a portion exposed from the concrete to be placed on the surface of the weir plate / finishing material main body 2 provided with the net material 3.

  In this example, the surface on one side of the dam plate / finishing material body 2 that contacts the concrete is a dam plate / finishing material body exposed surface 2a that does not have the net material 3 and does not have the resin mortar layer 4 laminated thereon. The dovetail groove 12 is formed on the plate / finishing material main body exposed surface 2a. Since the other configuration is the same as that of the first example, the description of the first example is cited.

  In the present example, as in the first example, the net material 3 has an end 3a protruding from the end of the resin mortar layer 4 to the outside of the resin mortar layer 4 in an arbitrary length-free state. However, the end 3 a of the net material 3 may not protrude from the end of the resin mortar layer 4 to the outside of the resin mortar layer 4.

  The dam plate / finishing material 1 configured as described above has sufficient strength as a mold for molding the concave and convex portions of concrete, as in the first example. And, when finishing the waterproof layer holding concrete on the roof of the building, when constructing the uneven part of the concrete on the waterproof layer, the formwork of the uneven part can be built with the barrier plate / finishing material 1, and the waterproof layer holding concrete It is not necessary to remove the barrier plate / finishing material 1 for constructing the formwork after the placement. Moreover, since the weir plate and finishing material main body 2 is formed of an elastic material, it serves as a joint that absorbs the expansion and contraction of the concrete, and the joint material for absorbing the expansion and contraction of the waterproof layer holding concrete around the uneven portion. There is no work to arrange separately.

  Further, in this example, the surface on one side of the barrier plate / finishing material main body 2 that contacts the concrete is the barrier plate / finishing material main body exposed surface 2a in which the net material 3 is not provided and the resin mortar layer 4 is not laminated. Since the dovetail groove 12 is formed in the barrier plate / finishing material main body exposed surface 2a, the barrier plate / finishing material 1 is arranged on the waterproof layer laminated on the roof slab so that the mold of the uneven portion is formed. When the waterproof layer presser concrete is placed, the waterproof layer presser concrete enters the dovetail groove 12 formed on the barrier plate / finishing material main body exposed surface 2a, and enters the dovetail groove 12 to solidify the waterproof layer. Since the pressing concrete becomes ants, it is possible to prevent peeling of the barrier plate / finishing material 1 from the waterproof layer pressing concrete.

  Moreover, in this example, since the end 3a of the net member 3 protrudes from the end of the resin mortar layer 4 to the outside of the resin mortar layer 4 in an arbitrary length-free state, the net member 3 is laminated on the roof slab. When the weir plate / finishing material 1 is placed on the waterproof layer thus formed to form a concavo-convex portion, and when the waterproof layer holding concrete is placed, the resin mortar layer 4 starts from the end of the resin mortar layer 4. Since the end portion 3a of the net member 3 projecting outside is buried in the waterproof layer holding concrete and functions as an anchor, the barrier plate / finishing material 1 is more reliably peeled from the waterproof layer holding concrete. Can be prevented.

  Since the usage example of the weir plate / finishing material 1 configured as described above is the same as the first example, FIG. 4 showing the usage example of the first example is used, and the description thereof is omitted.
