Description

[Detailed Description of the Invention] The present invention relates to a drainage construction structure for rainwater etc. at a part of the second floor corner of the boundary between the first floor roof and the second floor portion of a two-story house.

The boundary part 3 between the first floor roof 1 and the second floor part 2 of a two-story house (Fig. 1) has a structure that allows rainwater to easily enter.

This is particularly noticeable in the corner 4.4' of the second floor.

Rainwater enters the interior through this boundary, causing the construction materials to rot and reducing the durability of the house.

For this reason, in conventional houses, the area around the boundary was hardened with plaster or mortar to prevent rainwater from entering, but prefabricated houses and others use the dry construction method for ease of construction and shortening the construction period. However, the above method cannot be used in this country, and various other waterproofing methods have been used.

However, this waterproofing method also had the disadvantage that many of the members used were processed on-site during construction, and complete waterproofing could not be achieved due to the precision of the processing.

The present invention eliminates these drawbacks and provides a drainage construction structure for a part of the second floor corner of a two-story house that exhibits a complete waterproofing effect.

In FIGS. 2 and 3 showing the members used in the present invention,
5 is L made of metal such as iron or material such as synthetic resin
It is a shaped lower drain plate, and includes drains 6, 6' whose ends are folded back to face both ends, and a stepped portion 7 whose L-shaped corners are bent at right angles.

8 is a rubber whose surface is provided with wavy grooves 9 in one direction;
A water-blocking wall 10.10' which is a rectangular drainage corner sheet made of synthetic resin, metal, etc., which has one side parallel to the groove 9 at its corner and is connected to this one side and the adjacent side at a predetermined height.
A rectangular notch 8' is provided.

In Fig. 4, which shows an example of the drainage construction structure at part 4 of the second floor corner according to the present invention, the area near the boundary between the second floor part and the roof made by stretching roof boards over the rafters. Roofing splints 11, 11 are attached to the roofing splints 11, 11, and then a sheet 12' made of waterproof material is applied to drain the corners, and the roofing splints 11.11 are raised to the specified height to complete the entire first floor roof. The roofing 12, 12 is installed on the roof.

A small base wood 13 for fixing the roofing splint 11 and the roofing 12 divided at the boundary part of the gable side 15 is nailed to the roof part at the boundary.

After installing a suitable roofing material 17' such as cement tiles or colored asbestos slate boards on the first floor roof of the girder side 16, the large base wood 1
4 to the boundary part of the girder side 16 in the same way as the small base wood 13.
Nail to the floor roof.

Next, as shown in the figure, the drainage corner sheet 8 is placed at the second floor corner so that the water-blocking wall 10 in the direction of the groove 9 is in close contact with the longitudinal direction of the base wood 13, and the other water-blocking wall 10' is in close contact with the end of the base wood 13. After installing the lower drain plate 5 in a part, the lower drain plate 5 is installed on the small base tree 13 so that its lower part overlaps the upper part of the drain corner sheet 8, that is, the water blocking wall 10 and the part 8'' where the notch 8' is located. Then, the lower draining board 5 is fixed by overlapping and nailing the large base wood 14 to the small base wood 13.

Subsequently, a roofing material 17 is stretched over the roof of the gable side 5 including the roof portion of the lower draining board 5 and the upper surface of the draining corner sheet 8.

In the part of the draining corner sheet 8, the roofing materials 17' and 17 are doubled.

Furthermore, add the missing large base wood on the girder side 16 and install the upper draining plate 18 on top of the large base wood 14 and 14' as shown in the figure.

(The added part of the large base wood and the upper drain plate on the gable side 15 are not shown.) The upper drain plate 18 between the gable side 15 and the girder side 16
are connected with a corner drainer at a part of the second floor corner to make it completely waterproof, and the large base wood 1 is equipped with an upper drainer board 18.
4. Build the exterior wall of the second floor by fixing the exterior wall panel to the exterior wall panel sill plate fixed on top of 14'.

During rainfall, rainwater and other large portions flow toward the roofing material 17. Therefore, it flows along the lower draining plate 5 between the step 7 and the backsplash 6, and is further discharged through the groove 9 of the draining corner sheet 8 to the roofing material 17'.

Rainwater, etc. on the draining corner sheet 8 is reliably drained downward without spreading laterally due to the grooves 9.

Also, part of the second floor corner on the gable side 15, small base wood 13 and girder side 16
Since the water-blocking walls 10 and 10' are provided at the portions that come into contact with the walls, it is possible to reliably prevent rainwater from entering the interior.

Furthermore, since the grooves 9 reliably perform their functions even if they are not very deep, there is no need for the roofing material 1 to be very thick.
Even if 7 and 17' are doubled, the roofing material 17 is not lifted up that much.

Furthermore, the grooves 9 serve as a cushion to protect the roofing material 17 and prevent it from cracking.

In the embodiment, a roofing sheet is stretched over the roofing board, but any other waterproof sheet may be used as long as it has a waterproof function equivalent to or better than the roofing sheet.

In addition, the lower draining board 5 is provided with a step 7, which is made to match the small base wood 13 used for fixing the roofing 12, etc., and when other fixing methods are used. Shape it accordingly.

Further, on the second floor corner part 4', the sub-base wood lower part draining board and related members are installed in a manner symmetrical to those on the second floor corner part 4'.

In the present invention, a rectangular notch having one side parallel to the groove is formed at the end corner of a sheet having wavy grooves facing in one direction on the surface thereof, and one side parallel to the groove and the other side. A water cut-off corner sheet is formed by providing a cut-off wall of a predetermined height on the other side adjacent to the cutout and forming the cutout, and the roofing material on the gable side of a part of the second floor corner of a two-story house is provided. The drain corner sheet is arranged at the bottom of the corner of the second floor so that the cutout portion is in close contact with the corner and the groove is oriented in the inclination direction, and the drain corner sheet is further folded at both ends so as to face each other. A lower draining plate having a beveled end shape is formed, and the lower draining plate overlaps the horizontal portion of the lower draining plate with the upper part of the draining corner sheet, and the bending line of the lower draining plate is oriented in an inclined direction. Since this is a drainage construction structure in a part of the second floor corner of a two-story house, which is located along the gable side boundary, rain ice that has penetrated beyond the roof material can be removed from the lower drainage drainage. The board and draining corner sheet ensure drainage, and the water-blocking walls and grooves of the draining corner sheet reliably prevent water from seeping into a part of the corner of the second floor, demonstrating an extremely excellent waterproofing effect.
Since no on-site processing is required, it is suitable for dry construction methods.
