Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a sealing structure for an exterior wall panel.

[Prior Art] As an external wall structure of a building, there is a structure in which a plurality of external wall panels are supported horizontally adjacent to each other on a building structure, and these horizontally adjacent external wall panels are, for example, Lower floor exterior wall panels and roof panels installed on the lower floor side,
It is arranged above wall components such as eaves and window frame members.

Joints are formed between adjacent exterior wall panels, and these joints have traditionally been closed by inserting gaskets or applying putty or caulking, as described in IXF Publication No. 58-44822. And it was waterproofed.

[Problems to be Solved by the Invention] However, when a gasket is inserted into a joint to close it, rainwater sprayed onto the gasket infiltrates the back side of the gasket, and further infiltrated rainwater flows down the gasket. There was fear. When rainwater flows down the gasket, there is a risk that the rain ice may flow from the lower end of the gasket to the inner side of the wall bottom member. In particular, if the lower wall member is an exterior wall panel on the lower floor or a window frame member on the lower floor, f
There were cases in which falling rainwater entered the indoor side of the lower floor along the inner side of the lower wall member.

An object of the present invention is to reliably and easily perform waterproofing on the lower end side of a joint.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an elongated gasket at the joint portion that is arranged above the wall lower member and occurs between mutually adjacent outer wall panels. In the sealing structure of the outer wall panel that is inserted and closes the joint, a water receiving member covering the lower end of the gasket is attached to the lower end of the gasket, and the drain port of the water receiving member is connected to the outer surface of the wall lower member. It is arranged so that it extends further outward.

(Function) According to the present invention, rainwater enters the back side of the gasket,
Even when the rainwater flows down through the gasket, the water receiving member covering the lower end of the gasket can catch the rainwater flowing down. moreover,
Rainwater received by the water receiving member is drained outward from the outer surface of the lower wall member through the drain port. This makes it possible to reliably and easily perform waterproofing on the lower end side of the joint without allowing rainwater to enter the inner side of the wall lower member.

[Embodiments] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The lower edge of B and the upper edge of the lower floor exterior wall panel 18A are each covered by the decorative cover 38. In this way, the outer wall of the unit house is formed as shown in FIG.

Next, the above embodiment will be explained.

According to the above embodiment, if rainwater sprays onto the upper floor joint 25B into which the gasket 35B is inserted, the gasket 35
Even if rainwater intrudes into the back side of B, the infiltrated rainwater flows down the surface of the gasket 35B as shown by the arrow, and the rainwater flows down into the gasket 35B.
It will be received by a water receiving member 45 that covers the lower end of the. Furthermore, the rainwater received by the wooden receiving member 45 is drained by a drain port 47 arranged on the outer side in the horizontal direction (arrow Y direction) with respect to the outer surface of the lower floor external wall panel 18B (wall lower member). Water is drained to the outside of the panel as shown by the arrow in Figure 1. At this time, the rainwater drained through the drain port 47 flows downward along the back surface of the water stop plate 50. This makes it possible to reliably and easily waterproof the lower end of the upper floor joint portion 25B without allowing rainwater to enter the indoor side of the lower floor.

Further, according to the above embodiment, the rainwater flowing down the back surface of the gasket/gasket 35B as shown by the arrow is prevented by the presence of the water receiving member 45, so that the rainwater flows downward from each waterproof sheet 27A,
Since there is no direct dripping onto 27B, the durability of the sheet is improved.

Further, according to the above embodiment, the protrusion 29 of the male rail portion 30 provided on the waterproof sheet 27A attached to one upper floor outer wall panel 18B adjacent to the upper floor side and the other upper floor outer wall panel By pulling down the slider 43, the grooves 31 of the female rail section 32 provided in the waterproof sheet 27B attached to the waterproof sheet 27B can be reliably and easily engaged with each other.

In addition, since the upper end of each waterproof sheet 27A, 27B is supported by the back side of the upper floor exterior wall panel 18B that stands vertically, each waterproof sheet h27A, 27B is vertically attached to the back side of the upper floor exterior wall panel 18B. This prevents rainwater from entering in the horizontal direction between the waterproof sheets 27A, 27B and the lower end of the upper floor outer wall panel 18B in the gap 26.

Further, the lower end of each waterproof sheet 27A, 27E is pasted to the upper surface of the panel 19 of the lower floor exterior wall panel 18A with double-sided adhesive tape 36, so that the lower end of each waterproof sheet 27A, 27B is rolled up. The sheets 27A, 27B
Rainwater is prevented from entering the room from between the lower end of the panel and the face material 19 of the lower floor outer wall panel 18A.

Also, the joint part of the attached waterproof sheets 27A and 27B.
By storing one side inside the upper floor joint part 25B and further inserting a gasket 35B into the joint part 25B, the lower end of the upper floor spout part 25B is connected to the water sheets 27A, 27 on both sides.
B and the gasket 35B make it possible to achieve double sealing, thereby ensuring waterproofing of the gap 26 between the joints 25A and 25B.

Furthermore, the outer surface area of the gap 26 including the hanging portions of the gap 26 and the waterproof sheaths 27A and 27B is covered by a municipal board 50, and the upper end of the main wooden board 50 and the upper floor outer wall panel 18
B is sealed by a sealing member 51. As a result, rainwater spraying against the outer wall of the building is sealed on the primary side by the city water board 50, and further sealed on the secondary side by the above-mentioned waterproof sheets 27A and 27B, so that rainwater is not directed toward the indoor side. It is possible to completely block rainwater from entering.

Moreover, a corresponding area of the gap 26 where the real wood board 50 is arranged is covered with a decorative cover 38 attached to the fixture 37, making it possible to improve the appearance of the building.
