Description

[Detailed Description of the Invention] The present invention relates to a water-stopping structure at the top of a panel constituting the outer wall of a building.

Panel wall construction, which is widely used today, consists of a number of panels attached directly or via mounting brackets to the wall edges extending between columns or studs, and so-called joint bars placed at their joints. Generally, it is associated with a water-stop structure at the top such as a rooftop floor to prevent rainwater from entering the inside of the panel, that is, the indoor side.

Conventionally, the basic concept of this type of water-stopping structure was to seal the space between the water-stopping structure element such as the Kasagi plate and the exterior panel to directly prevent rainwater from entering between the two. It was there.

For this reason, a structure has been adopted in which a wet water-stopping material is mainly filled between the water-stopping structural element and the exterior panel.

However, the stop wood inevitably deteriorates over time, and its deterioration reduces its water stop effect, allowing the intrusion of rainwater, especially rainwater blown under pressure by the action of the wind.

In addition, filling with water-stopping material depends on on-site work, but it is not only work at height, but also the work involves filling water-stopping material into relatively small gaps, making it difficult to work and prone to uneven filling. , the desired water-stopping effect may not be obtained in some cases.

The purpose of the present invention is to improve such conventional water-stopping structures, and to provide a so-called open water-stopping structure in which there is no filling between the Kasagi plate, which is a water-stopping structural element, and the exterior panel. plan.

The water-stopping structure at the top of the exterior panel according to the present invention includes placing a water-stopping material made of an elastic material at the upper end of the exterior panel, surrounding the water-stopping material with a space around it, and having one end attached to the exterior panel. Kasagi plates that are bent close to each other to create a gap are arranged, and a cap material that presses and holds a water-stopping material made of an elastic material is connected and supported by brackets attached to pillars of a building, and the brackets The Kasagi plates are connected and supported via a sheet-like sealing material, and the upper end of the exterior panel is liquid-tightly sealed by the water-stopping material, while the gap is provided between the Kasagi plate and the exterior panel. By creating a structure in which the space around the waterproof material communicates with the atmosphere through the gap, the pressure inside and outside of the space is equalized, thereby preventing rainwater from entering from the upper end of the exterior panel to the indoor side. It is characterized by

The features of the invention will become clear from the following description of the illustrated embodiment.

As shown in FIG. 1, an exterior panel 10 constituting the exterior wall of a building includes a plurality of panels 12 and joint bars 1 between the panels.
4, and the joint bar is attached to a wall side edge 20 fixed to a steel column 16 by bolts and nuts 18.

A bracket 24 is disposed on the inside of the upper end 22 of the exterior panel 10, that is, in contact with the pillar 16 side, and is approximately the same width as the wall edge 20 and is formed into a generally U-shape as a whole. , a vertical portion 24b and an inclined portion 24C, and is fixed to a mounting angle member 26 welded to the column 16 with a bolt and nut 28 at the horizontal portion 24a.

At the upper end 22 of the exterior panel 10, a water stop material 30 made of an elastic material such as Moltoprene is arranged.

The water-stop material has an end surface 22 a and an outer surface 22 under a compressed state.
The upper end portion 22 of the exterior panel 10 is liquid-tightly sealed by being pressed and held by a cap member 32 screwed to the bracket 24.

A molded material can be used for each of the bracket 24 and the cap material 32, or the bracket and the cap material may be integrally molded.

Approximately 1 on the opposite side of the pillar 16 from the mounting angle material 26
A letter-shaped bracket 34 is welded thereto and consists of a vertical portion 34a extending upwardly from the column 16 and an inclined portion 34b bent from the vertical portion.

The inclined portion 34b is the inclined portion 24C of the bracket 24.
Although at a lower height, their slopes are approximately equal.

A Kasagi plate 36 is disposed on each of the inclined portions 24C and 34b of the bracket 24.34, and the Kasagi plate is screwed to the inclined portion 24C via a sheet-like sealing material 38, and is attached to the inclined portion 34. b is fixed with screws via the bent portion 42 of the supporting iron plate 40.

The Kasagi plate 36 extends linearly to the exterior panel 10 side and the opposite side, respectively, and has an overall appearance that slopes downward from the exterior panel side to the opposite side.

The Kasagi plate 36 also has an exterior panel 10 on one side thereof.
A space 44 is provided around the water stop material 30 disposed at the upper end 22 of the
The part 46 parallel to the exterior panel is bent at a point 48 so as to secure and surround it, and then the part 46 parallel to the exterior panel is bent at a point 48, and then the part 50 is bent in a direction close to the exterior panel.
It is bent again at a point indicated by , and further bent at a point indicated by reference numeral 56 so that the tip portion 52 extends parallel to the exterior panel 10 with a gap 54 in between.

Instead of the illustrated example, the tip portion 52 extending parallel to the exterior panel may be cut off as long as the gap 54 is secured.

On the side opposite to the exterior panel 10 where the upright iron plate 40 is placed, the Kasagi panel 36 is bent in the same manner as described above, and has an appearance that hangs down along the upright iron plate.

As described above, between the exterior panel 10 and the Kasagi plate 36, the gap 54 and the space 44 that communicates with the atmosphere through the gap surround the water stop material 30 and the cap material that holds it, so that rainwater does not escape. It is possible to penetrate up to the space 44.

However, since the space 44 is always at the same pressure as the outside, the rainwater that has entered is immediately drained away.

Furthermore, the action of the water-stop material 30 that seals the upper end of the exterior panel under compression can prevent rainwater from passing through the upper end of the exterior panel 10 and entering the indoor side.

In this way, the simple structure prevents rainwater from entering at the top of the exterior panel, and since filling work is eliminated, the construction of the water-stopping structure is easy and highly reliable. Since the use of wet sealing material is eliminated, effects such as no reduction in water-stopping effect due to aging can be obtained.
