DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain structure for preventing rainwater transmitted through a building from entering a room from the lower end of an outer wall, and a method of constructing the drain structure.

[0002]

2. Description of the Related Art Generally, in a house or the like, rainwater transmitted through an outer wall is prevented from entering a room from a lower end surface of the outer wall.
Mortar or the like is filled in the gap between the lower end of the outer wall and the top end of the foundation, and the outer wall is sloped down (conventional technology 1). In recent years, in prefabricated houses and the like, in order to save labor at the assembly site, there is a method of installing a drain plate near the lower end of the outer wall in advance to prevent rainwater from entering (prior art 2, utility model). See Registered Publication No. 2560435).

[0003] In the above-mentioned prior art 1, in a unit building in which a building is formed into a substantially box shape by joining columns and beams,
Referring to FIG. 9, reference numeral 1 denotes a foundation, 2 denotes an outer wall,

The space between the lower end of the outer wall 2 and the mortar 9 is filled on the foundation 1 and the outer wall side is sloped down to prevent rainwater 8 from entering.

[0004]

However, the prior art as described above has the following problems. That is, in the prior art 1, 1) cracks such as shrinkage occurred due to the mixing of the mortar, and there was a possibility that rainwater might enter from the cracked portion. 2) The mortar filling part was cracked by horizontal force, vibration, and the like from the building upper structure, and there was a risk of rainwater infiltration from the cracked part. 3) The work of filling the mortar into the gap between the lower end of the outer wall and the foundation required skill, and the finish was uneven, the floor beam and the mortar were not in close contact with each other, and there was a risk of rainwater infiltration.

[0005] Further, in the prior art 2, 1) Since it is attached to the outer wall in advance, the lower portion of the outer wall pops out, and special curing is required for transportation, temporary storage, and the like. 2) Because it is pre-installed on the outer wall, it is not possible to make site adjustments to the street of the foundation, and irregularities occur in the length direction, resulting in poor appearance after construction.

The present invention has been made in view of the above-mentioned problems, and has as its object to solve these problems, prevent infiltration of rainwater, and improve appearance and design.

The end cap member 30 is attached. At this time, the protrusion dimensions of the draining material protruding corners 3A are adjusted to the protrusion dimensions of the draining members 3 on both sides thereof. When the projecting dimensions of the drainers 3, 3 are different on both sides of the projecting corner, a projecting corner of a shape corresponding to this is used. The same applies to the corners.

As shown in FIG. 6, the method of attaching the drainer 3 is as follows. The adhesive 10 containing the vinyl bag 101 is pushed out to the rear side of the inverted drainer 3 so that the legs 32 are hidden, and the drainer 3 is overfilled. This is turned over, and the mounting piece 31 is mounted on the floor beam 6 via the elastic body 4. Then, a wedge-shaped spacer 20 is driven between the lower end of the outer wall 2 and the inclined piece 34 of the drainer 3, the leg 32 of the drainer 3 is pressed against the top end of the foundation 1, and the mounting piece 31 is attached to the floor beam 6. By pressing against the side surface, the rebound of the elastic body 4 is stopped, and the protrusion dimension of the drainer 3 is adjusted. Then, after correcting the overall steps, floating, and streets, the surface of the drainer 3 is wiped clean, and left untouched for more than one day for curing. Then, after the adhesive 10 is cured, the spacer 20 is removed.

The spacer 20 is formed of an elastic synthetic rubber such as ethylene propylene diene terpolymer (EPDM) or the like, and as shown in FIG. Projection 22 at rear end
Is provided. The height of the protrusion 22 is about 5 mm, the length of the base is 30 mm, the height including the protrusion 22 is 19 mm, and the length of the spacer 20 is 75 mm. If the gap between the outer wall 2 and the draining material 3 is widened with an unacceptably high accuracy than expected, the spacer 20 is turned upside down as shown in FIG.
By contacting the draining member 2 with the draining member 3, the draining member 3 can be strongly fixed because it can cope with the wide gap.

According to the draining structure of the present embodiment, a draining material outgoing corner 3A or a draining material entering corner 3B which is continuous with the draining material 3 is provided at an outer corner or an inner corner of the outer wall 2. The construction of the drainage structure at the corner or in the corner becomes easy, and the construction period of the on-site work can be shortened.

Further, according to the construction method of the draining structure of the present embodiment, the mounting piece 31 of the draining material 3 is attached to the floor beam 6 in a watertight state on the back side of the lower end of the outer wall 2, and the back side of the inclined piece 34 is bonded. In the step of joining to the top end of the foundation 1 with agent 10,
Since the wedge-shaped spacer 20 is driven between the lower end portion of the outer wall 2 and the inclined piece 34 of the drainer 3 and the spacer 20 is removed after the adhesive 10 is cured, the inclined piece 34 is formed by the driven spacer 20. The adhesive 10 is pressed against the top end to spread the adhesive, and the adhesive 10 is cured in the pressed state, so that the adhesion can be secured.

In this embodiment, the spacer 20 is
Since it is formed of elastic rubber, the surface of the drainer 3 is not damaged. Further, even if the inclined piece 34 is curved with a slight radius, it can follow the elastic deformation of the spacer 20. Further, the spacer 20 is economical because it can be used many times.
