Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is directed to an entrance corner to prevent water leakage at an entrance corner formed by intersecting three planes exposed to the outside in a building. The present invention relates to a sheet for waterproofing a part of a corner.

[Prior Art] Conventionally, as shown in FIG. 3 and FIG. 4, water leakage is prevented at an entry corner 14 formed by intersecting three planes 11, 12, 13 exposed to the outside in a building. As the entry corner corner water stop member to be installed for this purpose, there are those shown in FIGS. 5 and 6. FIG. 5 shows a rubber plate 15 formed into a shape that closely adheres to the shape of the corner 14 at the corner of the corner, and FIG. 6 shows that a rectangular thin metal plate 16 is partially cut and bent, By superimposing the vicinity of the cutting line, the shape is brought into close contact with the shape of the corner of the entering corner, and then caulking 17 is applied.

[Problems to be Solved by the Invention] Although there is no particular problem in the above-mentioned conventional ones when three planes intersect each other perpendicularly, for example, one of the three planes is a roof. In this case, the roof is different depending on the requirements of appearance, drainage, strength, etc., and there has been no general-purpose waterproofing material having a shape that can satisfy all of the different roof inclinations in terms of adhesion. Therefore, there is a problem that it is necessary to take either means of preparing a waterproof material having a different shape each time, or processing it for mounting depending on the shape of the corner of the entering corner. There is.

An object of the present invention is to provide a sheet for waterproofing water in the corners at the corners that solves the above problems.

[Means for Solving the Problems] Description will be made with reference to the drawings. In order to achieve the above purpose,
The waterproof sheet for entering corners according to the present invention is formed by three planes exposed to the outside of a building vertically intersecting each other, and two planes of the three planes vertically intersecting each other. In the sheet for waterproofing corners of corners having obtuse angles, that is, an angle between one of these two planes and the other remaining plane is greater than 90 degrees, the first rectangular portion 1,
Second and third rectangular portions that share one side with a pair of adjacent base sides 1a and 1b of the first rectangular portion 1.
2, 3 and a fan-shaped portion 4 sharing the intersection 1c with the base sides 1a, 1b and filling a portion sandwiched by the other sides 2a, 3a of the second and third rectangular portions 2, 3 Bending grooves 6 are formed radially around the intersection 1c of the fan-shaped portion 4 and on the sides 1a, 2a, 2b, and at least a part of the fan-shaped portion 4 is adjacent to the first rectangular portion 1. It is possible to fold around the intersection 1c of the base sides 1a and 1b that meet each other to form a small fan shape 4a, and to bend the second and third rectangular portions 2 and 3 in directions approaching each other.

[Operation] In the above-mentioned sheet for waterproofing corners at corners, at least a part of the fan-shaped portion 4 is formed along the groove 6 with the intersection 1c of the adjacent base sides 1a, 1b of the first rectangular portion 1 as the center. Folding,
By forming the small fan-shaped portion 4a and bending the second and third rectangular portions 2 and 3 along the groove 6 in the direction of approaching each other, one of the three planes forming the corners of the corners is formed. Two planes intersect perpendicularly to each other, and any one of these two planes, and the other remaining planes make an angle of 90 to 180 degrees, any of the three planes. It is possible to make a shape that can be closely attached to.

[Embodiment] FIG. 1 is a developed plan view showing an embodiment of a waterproof sheet for corners and corners of the present invention, which is made of a rubber elastic body having a thickness of 1 to 2 mm and is composed of the following parts. Composed. That is, 1 is a first rectangular portion, 1a and 1b are a pair of adjacent base sides of the first rectangular (including square) portion 1, 1c is an intersection of the base sides 1a and 1b, and 2 and 3 are Second and third rectangular portions sharing one side with the base sides 1a and 1b of the rectangular portion 1, 2a and 3a are base sides 1a and 1b of the second and third rectangular portions 2 and 3, respectively.
The other side 4 perpendicular to is a fan-shaped portion that fills the portion sandwiched by the other sides 2a and 3a.

To attach this to the corner corner 14 formed by the intersection of three planes 11, 12, 13 exposed to the outside of the building, for example, on the plane 11 corresponding to the roof and one of the vertical walls When the angle formed with the corresponding plane 12 exceeds 90 degrees and the angle formed with the plane 13 corresponding to the other of the vertical walls is a right angle,
Fold the fan-shaped part 4 along the groove 6 around the intersection 1c,
As shown in FIG. 2, a small sector 4a having a central angle α obtained by subtracting 90 degrees from the angle formed by the planes 11 and 12 is formed, and the second and third rectangular portions 2 and 3 are respectively formed into the first rectangle. Along the pair of adjacent base sides 1a, 1b of the portion 1, the parts 1 are bent along the groove 6 so as to approach each other. By doing so, the first and second rectangular parts 1 and 2 become parallel to the two planes 11 and 12 of the building, and the small fan shape 4a becomes flush with the third rectangular part 3 and the small fan shape is formed. 4a and the third rectangular part 3
The three planes are parallel to the plane 13 of the building.
11,12,13, 1st, 2nd, 3rd rectangular parts 1, 2, 3 respectively
Also, the small fan shape 4a can be closely attached.

The entry corner water stop sheet of the present invention is not limited to the above-mentioned embodiment, and three flat surfaces 11, 1 forming the entry corner are provided.
Any two planes of 2, 13 intersect perpendicularly to each other, and any one of the three planes 11, 12, 13 can form an angle of 90-180 degrees with the other plane. It is possible to make a shape that can be closely attached to.

In addition, the first, second, and third rectangular portions 1, 2, and 3 have side 1
A protrusion 5 having a triangular cross section for draining may be provided perpendicularly to a and 1b.

[Effects of the Invention] The present invention is configured as described above.
Even if they are manufactured in the same shape and the same size, any two planes among the three planes 11, 12 and 13 that form the corners of the corners intersect perpendicularly to each other, and the angle formed by the remaining one plane is
Three planes 11,1 at any angle from 90 to 180 degrees
It is possible to form a shape that can be in close contact with any of the surfaces 2 and 13, which has a high degree of freedom, enables mass production, and reduces manufacturing costs. In addition, the construction is easy on site, and there are no breaks in the corners and there is no need for caulking, which is extremely convenient.
