Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a formed rubber waterproof corner pad for waterproofing a sheet in a corner portion and a drainage portion of a building.

[0002]

[Prior art]

 The waterproofing method for the corners of a building is to cut and stick each body waterproofing material to cover it, or temporarily use a material other than a waterproofing material sheet such as a filler or unvulcanized tape to reinforce waterproofing. It was stopped. For example, as shown in FIG. 5, the corner protruding end 31 is reinforced by bonding sheets 32, 33, 34 or the like, or the periphery of the roof drain 41 is reinforced by a waterproof sheet 42 as shown in FIG. Such a construction method is adopted.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional ones, the corner portion with the most water leakage in waterproofing work is insufficient, and the original purpose of perfect waterproofing cannot be expected. For example, in the method shown in FIG. 5, the bonded portion 37 becomes 1/10 or less of the required bonding area and cannot follow the expansion and contraction of concrete or wood. And the biggest problem is that there is no danger of water leakage because there is no overlap of sheets at the tip 31 of the corner. Further, in the construction method shown in FIG. 6, the corner ridgeline 43 cannot be overlapped with the main body waterproof sheet, and a large number of small holes remain and the risk of water leakage is great.

In addition, when a conventional waterproof sheet is used, there are the following problems as a waterproofing method for corners. (1) Reinforcement method with waterproof sheet A method in which a molded rubber sheet is cut along the corners and bonded together, and there is a risk of peeling because the adhesive area of the sheet is 1/10 or less of the standard. (2) Reinforcement method with unvulcanized sheet Since the tip of the corner is filled with unvulcanized sheet, aging occurs in a short period due to the brittleness of the material. (3) Reinforcement method by caulking This method reinforces the tip and the deep part of the corner by filling caulking material, which has almost no relation to the waterproof material of the main body and the waterproofing effect is extremely low. (4) Reinforcement method by coating film A method of applying a waterproof film around the corners to obtain a constant film thickness, and the required film thickness cannot be obtained at the corner tip and corner ridge lines, and the main body The relationship with the waterproof sheet is extremely thin.

The present invention has been proposed in view of the above problems, and solves all of these problems at once in the waterproofing work of the tip, the deep part, and the ridge of the corner, which is the most important part in the waterproofing work. The purpose is to provide a waterproof corner pad.

[0006]

[Means for Solving the Problems]

 The present invention is a waterproof corner pad made of vulcanized rubber that is molded according to the three-dimensional shape of each corner or drain of a building. In other words, it is a molded vulcanized rubber waterproof corner pad that is molded according to the shape and size of each corner of the building and conforms to certain standards for construction work. This waterproof corner pad can be easily molded by hot pressing using a die standardized to a certain size, using EP rubber or chloroprene rubber as a base material.

[0007]

[Action]

 With the above configuration, the independent molded rubber pad maintains sufficient overlap and adhesive force with the main body waterproofing material, and it is possible to quickly and completely waterproof the corners that are difficult to work in the waterproofing work of the building. .

[0008]

【Example】

 Hereinafter, the waterproof corner pad according to the present invention will be described in detail with reference to an embodiment shown in the drawings. FIG. 1 is a perspective view of an embodiment in which a waterproof corner pad for projecting corners according to the present invention is attached to a projecting corner of a tower or the like in waterproofing work on a building roof. In the figure, 1 is a waterproof corner pad for projecting corners, 2 is an outer corner ridge line, 3 is a wall surface, 4 is a rising wall surface, 5 and 6 are main body waterproof sheets, and 7 is an overlapping portion of the waterproof sheets 5 and 6. . In this way, the waterproof corner pad 1 made of one seamless rubber molding material is adhered along the angle of the corner, and the tip of the corner and the ridge are completely covered, so there is no risk of water leakage. In addition, the corner pad and the waterproof sheet of the main body maintain a 10 cm overlap, and can sufficiently follow fluctuations in the waterproof substrate. The present invention can be similarly applied to the corners of the entrance corner of the building.

2 and 3 are a perspective view and a cross-sectional view showing a state in which the pipe around the roof is waterproofed by using the waterproof pad of the present invention. 11 is a waterproof pad, 12 is a notch for fitting the waterproof pad, 13 is a pipe, 14 is a waterproof sheet for the rooftop main body, and 15 is slab concrete for the building. In this case, only one place is a fitting notch (joint). However, all others are covered with a molded rubber waterproof pad 11 which does not create a gap in the bent portion at a right angle. It should be noted that the main body waterproof sheet 14 can have a sufficient overlap while being cut at the base of the pipe.

Next, FIG. 4 shows a cross-sectional view of the surroundings of vertical drains (roof drain, etc.) on rooftops, balconies, bathrooms, kitchens, etc., which are waterproofed using the waterproof corner pad of the present invention, Reference numeral 21 is its waterproof corner pad, 23 is a vertical drainage pipe, 24 is a main body waterproof sheet, and 25 is slab concrete of a building. The gap between the water distribution pipe 23 and the slab concrete 25 is completely covered, and complete waterproofing is possible around the drainage port where the water leakage rate is highest. Since this waterproof corner pad 21 for drainage has an overlapping width of 10 cm around the drainage, it is not necessary to bend and attach the main body waterproof sheet 24 to the inside of the water distribution pipe 23. All you have to do is cut along the inner ridge of.

As is apparent from the embodiments shown in FIGS. 1 to 4, the most characteristic features of the present invention are: (1) the tip of the protruding corner of the corner portion, the deep part of the entering corner, the pipe circumference, and the water pipe. The part that bends around at a right angle should be covered with one seamless corner pad. (2) No work is required at the corners of the main body waterproof sheet, and the mutual relationship between this waterproof corner pad and the main body waterproof sheet is extremely easy and strong to bond on a flat surface. (3) Waterproofing at each corner requires almost no special technology and can be performed in a short time, which is a few tenths of the conventional waterproofing at corners, and is extremely economical. Is.

EP-based rubber or chloroprene-based rubber is preferably used as the main material of the waterproof corner pad of the present invention. EP rubber is excellent in weather resistance, ozone resistance, cold resistance, and heat resistance, and chloroprene rubber is a material that is excellent in weather resistance, oil resistance, and heat resistance. Can be used. These rubbers are molded and vulcanized by a heat press using a mold of a certain standard that matches the shape and size of each corner of the building, such as for corners, corners, pipes, etc. To manufacture. The mold was cast from a metal capable of withstanding high heat, was a press type, and consisted of both convex and concave surfaces. The corner pad thickness of the product was adjusted to 1.5 mm, and the overlapping portion L was adjusted and fixed to 100 mm. In addition, for vulcanization, a predetermined amount of a curing agent, a pigment, and other additives are added to rubber as a main material, and the mixture is pressed by both concave and convex molds and heated at a temperature of 180 ° C. for about 20 minutes. The hardness of the corner pad after molding was adjusted with a curing agent in the range of 60 to 70 degrees.
