Description

[Detailed description of the device] Industrial application This device prevents rainwater from invading from joints between joints between building panels such as ALC and PC plates and window units such as sash windows to prevent intrusion of rainwater. The present invention relates to a watertight device between building exterior materials for reliably draining rainwater to the outside when it intrudes.

Conventional technology and problems to be solved by this invention In order to maintain the water-tightness between adjacent building exterior materials, the vertical joint between adjacent PC plates is conventionally on the indoor side as in Japanese Utility Model Publication No. 62-39203. Is sealed by pressing a dry seal material, and the outdoor side is closed by hitting a wet seal on site, and the joint between the PC plate and the window unit is closed on the indoor side with a wet seal material. A structure has been proposed in which the outdoor side is closed with a dry seal material. By the way, when arranging a building panel and a window unit in a row, the most important issue is how to ensure the watertightness of the corners where the four corners gather. Yet another problem is to minimize work on site to shorten the construction period.

The above-mentioned conventional structure still has the following problems.

That is, a gap due to a defective joint is likely to occur at the joint between the dry packing that closes the vertical joints on the indoor side and the wet seal that closes the horizontal joints. Further, it is not preferable to provide a wet sealing material for the seal on the indoor side, which is the final boundary for ensuring watertightness, in view of deterioration. The purpose of the present invention to solve these problems is to improve the watertight performance between the upper part of the window unit and the lower surface of the building panel, and the performance is not deteriorated over a long period of time. Even if rainwater enters there, it will not cross the watertight boundary on the indoor side, and this rainwater will be collected in the upper frame and drained from the upper frame to the outside, and the sealing work will be done on site. Is to reduce the construction period.

Means for Solving the Problems This invention has a construction panel such as an ALC version or a PC version that is connected to the left and right, and a window unit such as a sash window is installed below the construction panel, and the bottom surface of the construction panel The outdoor side portion between the upper surfaces of the window units is covered with a wet sealing material, and dry sealing materials are continuously attached to at least both vertical surfaces and the indoor side portions of the lower surface of the building panel in three directions. The upper frame is formed with a concave groove whose both ends are closed by a weir plate, and the bottom surface of this concave groove is provided with a drainage port communicating with a drainage port that opens to the outside of the room. To form a horizontal piece that has multiple rows of ridges on its upper surface.
The upper ends of the window units adjacent to each other on the left and right sides are connected to the indoor side by a catch pan having a rising piece, and the dry sealing material on the lower surface of the building panel adjacent to the ridge of the horizontal piece is pressed to form a corner portion. A watertight device between exterior building materials, characterized in that the innermost ridges provided on the rising piece and the horizontal piece of the catch pan are located on the indoor side of the dry sealing material, and Notches are formed in the ridges in a plurality of rows of the frame by shifting the positions.

Examples ALC plates and PCs are used as building exterior materials in which the present invention is implemented.
It is a combination of a building panel A such as a plate and a window unit B such as a sash window. Then, the building panels A are installed on the left and right, and the window unit B is installed below them,
The wet-side sealing material 1 closes the outdoor portion between the lower surface of the window unit B and the upper surface of the window unit B.

The dry sealing material 2 is continuously attached to at least both vertical surfaces and the lower surface of the building panel A on the indoor side in three directions. A horizontal piece 4 is integrally formed on the upper frame 3 of the window unit B so as to project toward the indoor side. The upper surface of the upper frame 3 is a groove 5, and both ends thereof are closed by a dam plate 6. Further, the bottom of the groove is inclined so as to rise toward the inside of the room so that the inside of the groove becomes higher, and a plurality of ridges 7 are provided on the upper surface of the horizontal piece 4 continuous with the groove. A groove 5 is formed between the threads. The ridge 7 is provided with a notch 8 so that water is drained from the notch 8 to the ridge 7 and the intrusion of rainwater from the outside is blocked by the ridge 7. By providing the cutouts 8 of the protrusions 7 in a labyrinth shape as shown in FIG. 4, it is possible to prevent rainwater from directly entering the room through the cutouts. In addition, the water collected in the groove 5 is drainage port 9a, drainage pipe 9b, hollow portion 9 of the mid-bone.
c. The water is drained through the lower frame drainage openings 9d, 9e, 9f that open to the outside of the room.

The upper end portions of the window units B adjacent to each other on the left and right are connected by a catch pan 10 having a rising piece 11 on the indoor side,
A corner portion C is formed by pressing the dry seal material 2 on the lower surface of the adjacent construction panel A against the ridge 7 of the horizontal piece 4.

The rising piece 11 of the catch pan 10 and the innermost ridge 7 provided on the horizontal piece 4 are positioned so as to rise to the indoor side of the dry seal material 2.

The barrier plates 6 of the adjacent horizontal pieces 4 are closed with a dry or wet sealing material.

Effect of the Invention (1) Since the dry sealing material is continuously mounted on at least three sides of the interior side vertical surfaces and the lower surface of the building panel, the lower surface sealing material and the double-row ridges of the upper frame are pressed against each other. Since the amount of wet sealing on the spot is reduced and the seal is dry, the sealing material on the indoor side does not deteriorate over a long period of time. Furthermore, the watertight boundary between the lower surface of the building panel and the upper frame on the indoor side is secured by the pressure contact between the ridge and the dry seal.

(2) The upper frame is provided with a concave groove with a dam plate at the end, and rainwater can be collected in this concave groove, and it can communicate with the drain port that opens to the outside of the room. The rainwater that has been prevented from entering at the boundary flows into the concave groove of the upper frame, is collected, and is quickly discharged to the outside of the room.

(3) A catch pan is provided in the corner where the building panel and the window unit gather together so as to straddle the upper frame connecting part of the window unit, and the catch pan is a protrusion that rises to the indoor side of the dry sealing material. Since it has a strip, rainwater that invades from the gap of the corner is stopped by the projection of the catch pan and flows into the upper frame, so it is the most difficult to ensure watertightness. You can

(4) In the other examples, a plurality of ridges on the upper frame are notched in a labyrinth shape so that water between the ridges is drained from the notches and rainwater from the outside directly passes over the ridges from the notches. It can be lost.
