Abstract

PURPOSE:To connect throating sheets with ease and certainty. CONSTITUTION:An upper side external wall 3 and a lower side external wall are installed above and below. Between them, the back face side of the lower end part 3a of the upper side external wall 3 and the front face side of the upper end part of the lower side external wall are covered with throating sheets 5 horizontally disposed. After that, the end parts 5a of the sheets 5 are connected to prevent water from leaking in from between the upper side external wall 3 and the lower side external wall. In this throating method for the external walls, the neibouring lower end parts 3a of the upper side external wall 3 are elastically deformed outward with a floating jig and then a rigid connection plate 9 is inserted between the back face sides of the lower end parts 3a. After that, the connection plate 9 is covered with the end parts 5a of the throating sheets 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a draining method for an outer wall in which water is drained between upper and lower outer walls installed above and below a building such as a house.

[0002]

2. Description of the Related Art Generally, a building unit system is known as one system for industrial production of buildings. In this method, a box-shaped building unit is preassembled at a factory, and a plurality of the building units are transported to a construction site and joined to each other to form a building. In this unit house, a gap is opened between the upper outer wall of the upper-floor building unit and the lower outer wall of the lower-floor building unit, so a drainer sheet should be placed between the upper outer wall and the lower outer wall. The water is prevented from entering the outer wall through the gap.

As a conventional water draining structure for the outer wall, there are those shown in FIGS. 5 and 6, for example. That is, the upper outer wall 3 is attached to the upper-floor building unit, and the lower outer wall 4 is attached to the lower-floor building unit, and the gap between the upper outer wall 3 and the lower outer wall 4 is waterproofed by the draining sheet 5. It has become.

More specifically, the draining sheet 5 has an upper edge portion attached to the back side of the lower end portion 3a of the upper outer wall 3 and a lower edge portion covering the surface side of the upper end portion 4a of the lower outer wall 4. There is. The ends 5a of the draining sheets 5 are connected by a fastener 6. This fastener 6
First, the state shown in FIG. 6A is connected to the outside of each outer wall 3 as shown in FIG. 6B, and then, as shown in FIG. It is inserted from c to the back side.

An example of this type is described in JP-A-63-35939.

[0006]

However, in such a conventional one, the work of connecting with the fastener 6 is difficult, and when the fastener 6 is inserted from the gap c, the gap c is narrow. Sometimes it may not be possible to insert it.

Therefore, it is an object of the present invention to provide a method for draining water from an outer wall in which the ends of the draining sheet can be easily and surely connected.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and between the upper outer wall and the lower outer wall that are installed vertically, the back surface of the lower end of the upper outer wall On the surface side of the upper end of the lower outer wall, a draining sheet is attached and arranged along the horizontal direction, and then the ends of the draining sheet are connected to each other from between the upper outer wall and the lower outer wall. In the draining method of an outer wall for preventing water from entering, after a lower end portion of the adjacent upper outer wall is elastically deformed outward by a floating means, a rigid body is provided on the back surface side of the lower end portion of the adjacent upper outer wall. The connection plate is inserted, and then the connection plate is covered with the end portion of the draining sheet to drain the outer wall.

[0009]

[Operation] According to such means, the lower end of the upper outer wall is floated, the connecting plate is inserted thereinto, and the end of the draining sheet is adhered. The workability is good, and there is no problem that the fastener does not enter the inside from the gap.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the present invention. The same parts as those of the conventional example will be described with the same reference numerals.

First, at the factory, upper and lower outer walls 3 and 4 are attached to each building unit in advance, and the draining sheet 5 is attached to the back side of the lower end 3a of the upper outer wall 3 to further As shown in FIG. 3, it is wound up on the front side.

After carrying these to the construction site and mounting the upper-floor building unit on the lower-floor building unit, the lower end portion 3a of the adjacent upper outer wall 3 is fixed by using the floating jig 7 as a floating means. Elastically deform outward. Specifically, the lifting jig 7 has a handle portion 7a and a lifting portion 7b,
The push-up portion 7b has a thicker base than the tip. Then, with the push-up portion 7b standing upright, as shown in FIG. 1A, the gap c between the adjacent upper outer walls 3 is increased.
After being inserted from above, it is rotated to a substantially horizontal state as shown in FIGS. At this time, the push-up portion 7b is inserted between the steel frame member 8 and the upper outer wall 3 as shown in FIG. 2, and the root side of the push-up portion 7b is formed thick as the push-up portion 7b rotates. Therefore, as shown in FIGS. 2 and 3, it is elastically deformed outward.

Thereafter, a connecting plate 9 made of stainless steel or aluminum is inserted from the lower side of the lower end portion 3a of the upper outer wall 3, and the connecting plate 9 is inserted between the steel frame member 8 and the draining sheet 5. (See Figure 3).

Next, the draining sheet 5 wound up on the surface side of the upper outer wall 3 is hung from the state shown in FIG. 3 in the direction of the arrow toward the surface side of the upper end 4a of the lower outer wall 4, and this An adhesive layer provided on the draining sheet 5 is applied to the surface side of the lower outer wall 4. At the same time, the end 5a of the draining sheet 5 is inserted through the gap c between the upper outer walls 3 and 3.
Remove the release paper from the double-sided tape (not shown)
The draining sheets 5 are bonded to the connecting plate 9 in a state where the end portions 5a of the draining sheets 5 are stacked (see FIG. 4). By disposing the draining sheet 5 in this manner, unlike the conventional one, the workability is good and the both draining sheets 5 can be surely connected as compared with the case where the fastener 6 is used.

Moreover, the watertightness can be further improved by stacking the end portions 5a of the water draining sheets 5 and laminating them together.

Further, a gap c between the upper outer walls 3 and the lower outer walls 4 is filled with a gasket (not shown) or the gap C is covered with a molding.

Although the embodiment of the present invention has been described above with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. However, it is included in this invention. For example, although the present invention is applied to the outer wall of the unit house in this embodiment, the present invention is not limited to this, and it is needless to say that the present invention can be applied to other buildings as long as a gap is formed between the outer walls. Further, although the lifting jig 7 is rotated as the lifting means to lift the lower end 3a of the upper outer wall 3, the invention is not limited to this, and the lower end 3a may be elastically deformed by any means. good.

[0019]

As described above, according to the present invention, the lower end portions of the adjacent upper outer walls are elastically deformed outward by the floating means, and then the lower end portions of the adjacent upper outer walls are deformed. By inserting a rigid connecting plate on the back side of the, then by attaching the end of the draining sheet to the connecting plate, unlike the conventional, compared with the one using the fastener 6, workability is good, It has a practically useful effect of being able to reliably connect both draining sheets.
