Description

[Detailed Description of the Invention] [Technical Field] The present invention provides an exterior wall that prevents rainwater from penetrating into the interior through the horizontal joints formed between an upper floor exterior wall panel and a lower floor exterior wall panel, and that improves the appearance. This relates to the drainage structure of the panel.

[Background Art] Conventionally, a drainage structure as shown in FIG. 3 has been adopted to prevent rainwater from entering through the horizontal joint portion 6 formed between the upper-floor outer wall panel and the lower-floor outer wall panel. In this structure, a lotion drainer 18 is disposed between an upper floor external wall panel 1 and a lower floor outer wall panel 2, and a drainer upper piece 19 formed by bending the lotion drainer 18 upward toward the indoor side is attached to the upper floor outer wall panel. A water cutter bottom piece 20, which is placed on the back side of the panel 1 and bent downward on the outdoor side of the lotion drainer 8, is placed on the front side of the downstairs exterior wall panel 2, and the lower end surface of the makeup water drainer 8 and the upper floor exterior wall panel 1. A waterproofing material 7 such as a sealant is filled in the gap formed between
A waterproofing material 7 is filled between 0 and the downstairs exterior wall panel 2. In this way, conventionally, lotion remover 1
Waterproofing material 7 filled with 8 and the upper floor external wall panel 1
The waterproofing material 7 performs primary waterproofing, and the draining top piece 19 performs secondary waterproofing. However, with long-term use, the waterproofing material 7 may deteriorate and peel, causing the waterproofing performance to deteriorate. It was sufficient.

[Purpose of the invention] The present invention was made in view of the above points, and the purpose is to provide a drainage structure for exterior wall panels that can improve waterproof performance and also improve the appearance. That is.

[Disclosure of the invention] In other words, the drainage structure of the exterior wall panel of the invention is as follows:
A water cutter 3 is arranged between the upper and lower floor exterior wall panels 1 and 2, and a water cutter upper piece 4 formed by bending the water cutter 3 upward toward the indoor side is placed on the back side of the upper floor exterior wall panel 1. At the same time, a lower piece 5 of the drain cutter 3 formed by bending downward on the outdoor side is placed on the surface side of the downstairs exterior wall panel 2, and is formed between the lower end surface of the upper floor outer wall panel 1 and the drain cutter 3. A waterproofing material 7 is filled in the gap between the base pieces 10 and 12, and a mounting piece 11 is provided on the upper end of the base piece 10 and a water cutter 12 is provided on the lower end of the base piece 10. Install the mounting piece 11 of the lotion drainer 8 on the outdoor side of the material 7 and attach it to the upper floor exterior wall panel 1.
A locking piece 16 fixed to the lower end and protruding from the back surface of the board 10 is locked to a receiving piece 15 of a water receiving part 14 protruding from the upper part of the downstairs exterior wall panel 2. The above object is achieved by performing primary waterproofing with the waterproof material 8, secondary waterproofing with the waterproof material 7, and tertiary waterproofing with the draining top piece 4.

The present invention will be described in detail below based on illustrated embodiments. As shown in Figures 1 and 2, the upper-floor exterior wall panel 1 and the lower-floor exterior wall panel 2 are arranged vertically with a slight gap between them, and there is a space between the upper-floor and lower-floor exterior wall panels 1 and 2. A drainage drain 3 is provided. This water drainer 3 is formed by bending a metal plate or the like, and includes an upper water cutter piece 4 bent upward on the indoor side of the mounting piece 9, and a lower water cutter piece 5 on the outdoor side of the mounting piece 9. It is formed by bending downward. The upper piece 4 of the drainer 3 is arranged on the back side of the upper floor outer wall panel 1, and the lower piece 5 of the drainer is arranged on the front side of the lower floor outer wall panel 2. A waterproofing material 7 such as a sealant is filled in the gap formed between the lower end surface of the upper floor external wall panel 1 and the mounting piece 9 of the drain cutter 3. A waterproof material 7 is also filled between the surface and the surface. The lotion cutter 8 is formed by bending a metal plate or the like, and is formed by providing a mounting piece 11 at the upper end of a base piece 10 and a water cutter 12 at the lower end of the base piece 10. This lotion drainer 8
is arranged on the outdoor side of the horizontal joint part 6 so as to cover the horizontal joint part 6 between the upper floor exterior wall panel 1 and the lower floor exterior wall panel 2, and a mounting piece 11 is attached to the lower end surface of the upper floor exterior wall panel 1 with screws 13 etc. It is fixed in place. A waterproof material 7 is filled between the mounting piece 11 and the upper floor outer wall panel 1. In addition, a water cutter 14 is fixed to the upper end of the downstairs exterior wall panel 2 with screws 13, and a locking piece 16 provided on the back side of the makeup water cutter 8 is hooked onto the receiving piece 15 of the water cutter 14. It is being Lotion drainer 8
A flow channel 17 is provided between the water section 12 and the surface of the downstairs outer wall panel 2.

Therefore, the rainwater that falls on the side joint 6 between the downstairs exterior wall panel 2 and the upper floor exterior wall panel 1 is primarily waterproofed by the makeup drainer 8, and even if rainwater were to infiltrate into the interior of the makeup drainer 8, The water is also flowed down from the flow channel 17, and the mounting piece 9 of the drain cutter 3
waterproofing material 7 filled between and the upper floor external wall panel 1
It is waterproofed by the draining water cutter 3 and the water cutting upper piece 4
It is waterproof and can reliably stop rainwater from entering. In addition, the waterproofing material 7 filled in the horizontal joint portion 6 is covered by the lotion drainer 8 and is not exposed to the surface, so it does not deteriorate and cause cracks or peeling, and can maintain its waterproof performance over a long period of time. It is possible. Also, the lotion drainer 8 is screw 13.
It is securely fixed to the outer wall panels 1, 2 by the water cutter 14, and the design effect can be enhanced by the pattern provided on the surface of the base piece 10.

[Effects of the invention] As described above, the present invention provides a water cutter between the upper and lower floor exterior wall panels, and a water cutter upper piece formed by bending upward on the indoor side of the water cutter is attached to the upper floor exterior wall. Place the lower piece of water cutter, which is placed on the back side of the panel and bent downward on the outdoor side of the water cutter, on the front side of the downstairs exterior wall panel, and between the lower end surface of the upper floor exterior wall panel and the water cutter. Since it is filled with waterproof material, rainwater that enters the building from the joint between the upper and lower floor external wall panels can be blocked by the waterproof material and draining top piece, and a make-up drainer can be installed on the outdoor side of the waterproofing material. At the same time, the upper end of the makeup drainer is fixed to the lower end of the exterior wall panel on the floor, so the makeup drainer can also be waterproofed and its waterproof performance can be improved.Moreover, the waterproof material is Since it is covered from the outdoor side by the lotion drainer, waterproof materials such as sealants will not deteriorate due to rainwater or light, and the waterproof material can perform its function over a long period of time. In addition, the top and bottom of the cosmetic water drainer are connected to the upper and lower exterior wall panels, respectively, by fixing the mounting piece and the locking piece. Installation to the exterior wall panel is ensured, and the connecting part between the locking piece and the water cutter is not visible even when viewed from below due to the presence of the water cutter. Furthermore, the lotion cutter is formed by bending so that a mounting piece is provided at the upper end of the base piece, and a water cutter is provided at the lower end of the base piece, so the external shape can be varied. It is possible to enhance the design effect of the mounting part by extending it.
