[Problems to be solved by the device]

 However, according to the above-mentioned conventional gasket, since water proofing is not performed thereafter, water leakage may occur. In order to improve this problem, a waterproof gasket made of a waterproof material such as styrene resin is also known, but styrene resin is easily pierced by a sharp object to open a hole, so water may leak from this hole. . Therefore, care must be taken during construction so that the sharp edges of the crosspiece do not penetrate the gasket. Also, the waterproof gasket made of styrene resin will be damaged if it is peeled off after it has been pasted once.Therefore, it cannot be peeled off and re-applied when the gasket is attached diagonally or in the wrong place. It was

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 2 shows a first embodiment of the present invention. As shown in FIG. 2, the gasket 20 for preventing leakage at the joint portion between the door and the window frame is composed of a gasket body 21, a tough film 22, and two release papers 23. The soft and waterproof gasket body 21 is made of a resin having a closed cell (CLOSE CELL), for example, EVA (ETHYLENE / VINYL ACETA TE). The gasket body 21 is formed in a flat plate shape and has a little compressive elasticity.

The tough film 22 is made of a strong plastic material having properties such as being difficult to pierce and tear, and is made of, for example, PVC (POLYVINYL CHLOREDE), and is attached to one surface of the gasket body 21. An adhesive is applied to the other surface of the gasket body 21 and the outer surface of the tough film 22 to form two attachment surfaces.

The release paper 23 is a thin film made of paper or plastic, and has an oil film layer on one surface. With this oil film layer, it is possible to repeatedly apply and release the release paper to the application surface. A brand mark is printed on the other side of the release paper. The gasket 20 having the above-described configuration has one long side formed in a step shape. The other long side is provided with notches of the number and shape corresponding to the members to be joined via the gasket 20. At the center of the gasket 20, a horizontal cutoff line 204 extending parallel to the long side and a vertical cutoff line 205 extending perpendicularly to the horizontal cutoff line 204 are provided. As a result, the gasket 20 can be divided from the horizontal cutoff line 204 and the vertical cutoff line 205.

Second Embodiment A second embodiment of the present invention is shown in FIG. As shown in FIG. 3, the gasket 30 for preventing leakage is composed of a soft and waterproof gasket body 31, two tough films 32 attached to one side and the other side of the gasket body 31, and two sheets of tough film 32. The tough film 32 is composed of two release papers 33, which are respectively attached to the two attaching surfaces formed by applying an adhesive to the outer surface of the tough film 32. As the material of the gasket main body 31, the tough film 32 and the release paper 33, the same materials as in the first embodiment can be used.

In the gasket 30 having the above structure, one long side 301 is formed in a step shape. The other long side 302 is provided with notches of the number and shape corresponding to the members to be joined via the gasket 30. At the center of the gasket 30, two horizontal cut lines 304 extending parallel to the long sides and a vertical cut line 305 extending perpendicular to the horizontal cut lines 304 are provided. Next, the shapes of doors and windows to which the gasket 30 according to the second embodiment of the present invention is applied will be described.

As shown in FIG. 4, a door and a window 40, which are usually manufactured by extrusion molding using an aluminum material, have upper, middle, lower three members between a left vertical member 41 and a right vertical member, which are two vertical members on the left and right. An upper horizontal member 43, a middle horizontal member 44, and a lower horizontal member 45, which are horizontal members of the book, are provided. The left vertical member 41 is formed with an upper joint portion 401, a middle joint portion 402, and a lower joint portion 403, which are three joint portions. Further, the right vertical member 42 is formed with an upper joint portion 404, a middle joint portion 405 and a lower joint portion 406 which are three joint portions. The upper joining portion 401 and the upper joining portion 404 are provided in positions facing each other in a shape facing each other. Similarly, the middle joint portion 402 and the middle joint portion 405 and the lower joint portion 403 and the lower joint portion 406 are provided in positions facing each other in a shape facing each other.

Since the gasket 30 is provided with sticking surfaces on both sides, three types of gaskets corresponding to the upper, middle, lower three horizontal members are used for the door and the window 40. Here, as shown in FIG. 5, in the door and the window 40, the upper shape of the lower cross member 45 and the upper shape of the middle cross member 44 are the same, and the lower shape and the middle cross member of the upper cross member 43 are the same. The lower shape of the material 44 is the same. Therefore, in the second embodiment of the present invention, one kind of gasket 30 corresponding to the shape of the inner cross member 44 is prepared, and the gasket 30 is used as it is for the middle joining portions 402 and 405, and the upper joining is performed. The upper part obtained by dividing the gasket 30 into two pieces from the horizontal cutoff line 304 is used for the parts 401 and 404, and the lower part obtained by dividing the gasket 30 into two pieces from the horizontal cutoff line 304 is used for the lower joint parts 403 and 406. use. Accordingly, one type of gasket 30 can be formed into three types of shapes and used for the joining portion of the three upper, middle, and lower cross members.

A method of attaching the gasket 30 to the joining portion will be described by taking the joining of the upper horizontal member 43 and the left vertical member 41 as an example. As shown in FIG. 6, first, one sheet of release paper 33 is peeled off, and the gasket 30 is attached to the wall of the left vertical member 41 at the position where the upper horizontal member 43 is to be joined. Next, the other release paper 33 of the gasket 30 is peeled off to position the upper horizontal member 43, and then the left vertical member 41 and the upper horizontal member 43 are screwed through the metal lock plate 51 as shown in FIG. The material 43 is tightened and fixed. Further, the upper horizontal member 43 may be positioned and the left vertical member 41 and the upper horizontal member 43 may be fastened and fixed without peeling off the other release paper 33.

As described above, according to the gasket 30 of the second embodiment, since the toughness film 32 is attached to both sides of the waterproof and soft gasket body 31, the toughness film 32 supports the gasket body 31. It For this reason, the gasket 30 is less likely to be damaged even if the application and the peeling are repeated, which is an effect that it is convenient for the construction work. Further, since the gasket main body 31 is protected by the tough film 32, even if the vertical member and the horizontal member are tightened, the sharp portion of the end face of the horizontal member is unlikely to pierce the gasket 30, and therefore the waterproof effect is high. Further, since the gasket 30 can be divided and used from the horizontal cutoff line 304 or the vertical cutoff line 305, one kind of the gasket 30 can be applied to the frame of doors and windows of various sizes and shapes. As a result, the stock of material can be reduced and the manufacturing cost can be reduced.

Even when the gasket 20 of the first embodiment is used, the same effect as that of the second embodiment can be obtained.
