DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for a building or the like, and more particularly to a waterproof structure provided on a building or the like having a rising portion such as a side wall.

[0002]

2. Description of the Related Art As a waterproof structure for a roof or the like having a rising portion such as a side wall, the structure shown in FIGS. 6 and 7 is conventionally known. In FIG. 6, A is a rooftop of a building, A1 is a roof side wall, and A2 is a roof slab portion. 1
Is a waterproof layer formed from the roof slab portion A2 to the side wall A1, and 4 is a protective layer formed on the waterproof layer 1 and is formed by driving concrete. 23
Is a cushioning material interposed between the side end of the protective layer 4 and the rising portion of the waterproof layer 1, and is formed of a foamed resin material. This cushioning material 23 is stretched with an adhesive or the like below the rising portion of the waterproof layer 1 when concrete as a protective layer is driven, and expands and contracts in the horizontal direction of the protective layer (concrete layer) 4 due to a temperature change or the like. It has the function of absorbing movement. Reference numeral 24 denotes an interposing material which is stretched over the horizontal portion of the waterproof layer 1 and is interposed between the protective layer 4 and the waterproof layer 1 made of concrete. It has functions such as soundproofing and shock resistance. by the way,
To form the waterproof structure as described above, first, the waterproof layer 1
The foamed resin plate 24 as an interposer is spread over the horizontal portion of the above, and then the cushioning material 23 is adhered to a predetermined portion of the side wall, that is, a portion facing the side end of the concrete protective layer 4, and concrete is driven into the protective layer 4 to form the protective layer 4. It is supposed to. FIG. 7 is a view showing another conventional example. In this case, the structure is exactly the same as the above-described conventional example, except that the cushioning member 23 has an inclined portion at a lower end portion.

[0003]

However, in any of the above-mentioned prior arts, it is difficult to adhere the cushioning member 23 to the rising portion of the waterproof layer 1, that is, to the wall surface portion. It takes a long time. The reason is as follows. That is, the cushioning material 23 is stretched over the rising portion of the waterproof layer 1 with an adhesive. However, since the waterproof layer is formed by laminating a waterproof sheet or the like in a number of layers, an inconsistent portion called an uneven portion is formed. Because of this, it is difficult to fix and attach the cushioning material 23 to a predetermined position on the vertical surface of the waterproof layer 1.
3 is deviated from a predetermined position. Such inconvenience frequently occurs particularly at a so-called corner where the corners come into contact with each other. Further, the above-mentioned conventional technique has the following disadvantages. That is, since both the interposition material 24 and the protective layer 4 provided on the waterproof layer 1 have sufficiently large surfaces covering the entire surface of the waterproof layer 1, for example, repair work, inspection work, and the like on the roof surface are performed. Interposer 2
When it becomes necessary to peel off the protective layer 4 and the protective layer 4 partly or completely, the work of peeling them off is extremely complicated, which causes a disadvantage that the working efficiency is reduced. In addition, since the protective layer 4 formed of concrete or the like expands and contracts due to a change in temperature, forming the protective layer 4 having a sufficiently wide surface as in the related art has a disadvantage that the protective layer 4 is cracked. As it occurs, the protective layer 4 presses the rising part of the building,
There is a possibility that the rising part of the building may be damaged.

[0004]

According to the present invention, a waterproof structure having a rising portion in a building or the like is provided with a waterproof layer extending from a plane portion of the building to the rising portion, and a waterproof layer provided on the waterproof layer. A cushioning material layer that is installed and laid with a plurality of cushioning materials of a predetermined size, and a plurality of protective materials formed by concrete casting are arranged side by side, and a protective material layer installed on the cushioning material layer And a joint member made of a foamed resin material provided between the plurality of cushioning materials and between the plurality of protective materials, respectively, wherein the cushioning material has a vertical portion and a horizontal portion formed integrally with each other to form a building. An object of the present invention is to solve the above-described conventional problem by using a side edge cushioning member installed from a flat portion to a rising portion and a flat cushioning material installed at a flat portion of a building.

[0005]

In the present invention, the side edge cushioning material installed from the flat portion to the rising portion of the building has a horizontal portion, and if this is bonded to the floor surface, the vertical portion can be easily converted to the rising portion. Even if concrete is driven into contact with a predetermined portion to form a protective material layer, the predetermined position can be easily held and no displacement occurs. In addition, since the cushioning material layer and the protection material layer are formed by a plurality of cushioning materials and protection materials each having a predetermined size, for example, when repairing and inspecting the roof surface, The cushioning material and the protective material can be easily peeled off, and the working efficiency can be improved. Then, even when the plurality of protective materials expand and contract due to a temperature change, the joint member made of the foamed resin material provided between the plurality of protective materials expands and contracts in accordance with the expansion and contraction of the protective material, and the joint member of the protective material expands and contracts. Since the energy of expansion and contraction is absorbed, it is possible to prevent cracks in the protective material, damage to the rising portion of the building, and the like.
