Description

The present invention relates to a drainer used as a waterproof material in the field of the building industry.

[Background Art] Since a building is required to have a high degree of waterproofness, various waterproof structures are incorporated in various parts. For example, Japanese Patent Application Laid-Open No. 63-51547 discloses a waterproof structure at a connection portion between a first-floor outer wall panel of a first-floor room unit and a second-floor outer wall panel of a second-floor room unit. Here, a flexible resin waterproof sheet is used. The waterproof sheet is fixed by sandwiching its upper end between the lower part of the structure of the second-floor room unit and the lower part of the second-floor outer wall panel, and the lower part of the waterproof sheet is connected to the lower end of the second-floor outer wall panel and the upper end of the first-floor outer wall panel. It is pulled out to the front side of the first floor outer wall panel through the space,
It is joined to the upper part of the first floor outer wall panel. With this waterproof sheet, it is possible to prevent rain falling or rainwater transmitted along the surface of the second floor outer wall panel from entering the inside of the second floor outer wall panel or the first floor outer wall panel.

[Problems to be Solved by the Invention] As in the above-mentioned prior art example, when the joining partner to the lower part of the waterproof sheet is an outer wall panel, the surface to be joined to the waterproof sheet in the outer wall panel is flat.
The construction was very easy and did not cause any problems.

However, there were cases where the construction condition was poor depending on the place where the waterproof sheet was used. For example, a member to be joined below the waterproof sheet is a member provided in the vicinity of the floor (hereinafter, referred to as a member to be joined), and, in the vicinity of the member to be joined, some other member (hereinafter, an obstacle) from the floor. .)
Are protruding. In such a case, the lower part of the waterproof sheet could not be joined to the member to be joined near the obstacle. However, even if an attempt was made to join the lower portion of the waterproof sheet to the obstacle, it was impossible to cover the waterproof sheet on the uneven obstacle. Therefore, there was some concern about the waterproofness of this part.

The present invention has been made in view of the above-described problems of the conventional technology, and an object of the present invention is to provide a drainage material for construction that can exhibit sufficient waterproofness even when used in a part having a complicated shape. There is where to try.

Means for Solving the Problems The present invention has been made to achieve the above object, and the gist of the invention is that (a) it is formed of resin and has both flexibility and self-retaining property, The main body is deformed so as not to extend along a straight line in the longitudinal direction, and (b) is formed of resin and has more flexibility than the main body, and is joined along the end of the main body. And a connection piece having either a male or female fitting part forming a part of the fastener formed at an edge part on a side away from the main body part. .

[Operation] The shape of the main body of the drainer is deformed to a shape suitable for avoiding the place of use and obstacles, and the end is deformed so as not to be along a straight line in the longitudinal direction. Since the main body has both flexibility and self-preserving properties, the main body can be freely deformed by applying an external force, and can be restored to its original shape by removing the external force. Therefore, when the fitting part of the connection piece of the drainer is fitted to the fitting partner, if the end of the main body is deformed linearly,
The fitting operation can be easily performed. If the external force is removed after the fitting, the main body returns to its original shape, and the appearance is beautifully finished.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 8.

FIG. 5 is a plan view of a unit house, in which a balcony unit 30 is provided to protrude outward from the second-floor room units 10 and 20. In this embodiment, the draining material is used at a portion where the room units 10 and 20 and the balcony unit 30 gather (part A in FIG. 5).

As shown in FIG. 1, a drainer 40 is attached to the lower part of the corner located at the part A in the room unit 10 so as to face the balcony.

The drainer 40 includes a main body 41 and a connecting piece 42.
The main body 41 is made of vinyl chloride resin,

The protruding portion 41b has a shape and a size necessary to cover an obstacle (not shown) protruding upward from the floor of the balcony unit 30 in the portion A. The main body 41 has both flexibility and self-retention. That is, the main body 41 retains the above-described shape (original shape) unless external force is applied, but the main body 41 can be freely deformed by applying external force as needed. After being deformed, when the external force is removed, the main body 41 is restored to its original shape. The connection piece 42 is also formed of a flexible vinyl chloride resin, but its flexibility is richer than that of the main body 41. The connecting piece 42 has one end extending in the longitudinal direction and the main body 41
Is welded to the edge of the protruding portion 41b and the edge of the flat plate portion 41a connected thereto. As shown in FIG. 2, a male fitting portion 42a is formed on the other edge of the connection piece 42 extending in the longitudinal direction over the entire length thereof.

The draining member 40 is joined to the corner column member 12, the lower beam member 13, and the corner stud 14 of the room unit 10 via the double-sided adhesive tape. Has been fixed. In the attached state, the lower edge of the drainer 40 is located above the lower edge of the lower beam member 13, and the connection piece 42 and the main body 41 connected thereto are connected.
End protrudes in a direction closer to the room unit 20 than the column member 12.

In addition, as shown in FIG.
A drainer 50 is attached to the lower part of the corner, which faces the balcony. The draining member 50 has a symmetrical shape with the draining member 40, and the connecting piece 42 of the draining member 40
Draining material 40 except that a portion corresponding to the male fitting portion 42a is a female fitting portion 52a fitted with the fitting portion 42a.
The structure of the room unit 20 attached to the structure 21 is the same as that of the drainer 40 except that the room unit 20 is symmetrical. 3, 4, and 6, the same drain portions as those of the drainer 40 are denoted by the same reference numerals as those in the 50s, and the room units 20. In the structure 21, the same parts as those of the structure 11 of the room unit 10 are denoted by the same reference numerals in the 20s with the same first digit, and the description of these structures is omitted.

Next, the assembling procedure will be briefly described, focusing on the part A.

First, the structures 11, 21 of the second-floor room units 10, 20, to which the drainers 40, 50 are attached in advance, are installed at predetermined positions. Then, the male fitting portion 42a of the drainer 40 is
0 is fitted to the female fitting portion 52a. Each of the above fitting portions 42a, 52
a is bent twice at a right angle in the middle of the longitudinal direction, but as described above, since the main body portions 41, 51 of the drainers 40, 50 are extremely rich, the straight portions are straightened. Thereby, the fitting can be performed without any trouble.
Then, after the fitting, the main body portions 41 and 51 are restored to their square original shapes by their self-preserving properties. FIG. 6 shows this state.

Next, the balcony unit 30 is replaced with the second-floor room unit.
Lift up from the lower side of the structures 11, 21
The obstacles (not shown) protruding from the floor of the balcony unit 30 at the portions are formed by the protrusions 41b, 51b of the drainers 40, 50.
And the balcony unit 30 is fixed at a predetermined position.
