Description

  The present invention relates to a structure for discharging rainwater entering a building through a joint portion of an outer wall panel surrounding the chimney in a building that houses a waste treatment facility including the chimney.

  In buildings containing waste treatment facilities such as melting furnaces and incinerators that handle waste, outer walls such as ALC panels (lightweight aerated concrete plates cured by autoclaves) from the viewpoint of landscape maintenance Panels are used to shield the chimney outer periphery of the waste treatment facility. As shown in FIG. 7, the outer wall panel 10 surrounding the chimney has a support angle 30 whose bottom end is joined to a steel beam 12 a that supports the floor of the chimney bottom of the building via piece angles 16 and 17. The lowermost end portion of the outer wall panel 10 and the water upper end portion of the folded plate roof 11 are substantially the same height. That is, the outer wall panel 10 surrounding the chimney is installed in a state of floating from the ground.

  In addition, the opening of the gap has an L-shaped cross section so that rainwater does not enter the building from the gap formed between the lowermost end of the outer wall panel 10 surrounding the chimney and the upper end of the folded plate roof 11. It is covered with a drainer 14, and the upper edge of the ridge drainer 14 is covered with a drainer 15. For draining the folded plate roof 11, for example, Patent Document 1 is helpful.

  As shown in FIGS. 8A and 8B, the joint portion 31 between the outer wall panel 10 and the outer wall panel 10 is filled with an acrylic or urethane sealing material 32 (see, for example, Patent Document 2). ). However, when several years have passed since the construction, the sealing material 32 deteriorates over time and a seal breakage occurs. When the seal breakage occurs, rainwater R enters the building through the joint part 31 provided in the vertical direction and falls from the roof, so that not only the plant equipment in the building will be disturbed, but also the operation. May have an effect. Further, in order to prevent rainwater R from entering the building through the joint portion 31 of the outer wall panel 10, there is a problem that costs are increased if the sealing material 32 is replaced.

In a building that houses a waste treatment facility with a waste treatment furnace, the chimney outer wall panel protrudes from the folded plate roof, and in addition, the folded plate roof is installed for the installation and installation of plant equipment into the building. There is a special circumstance that rainwater flowing downward through the joint portion of the outer wall panel cannot be received by the roof because it is a later process than the outer wall panel.
On the other hand, the above-mentioned water leakage trouble has not been recognized as a problem because it is a problem that does not occur in a normal building composed of an outer wall panel and a folded roof.

  The present invention has been made in view of such circumstances, and in a building that houses a waste treatment facility equipped with a chimney, drains rainwater that enters the building through a joint portion of an outer wall panel surrounding the chimney with a simple structure. An object of the present invention is to provide a leakage discharge structure that can be used.

In order to achieve the above-mentioned object, the present invention is a structure for discharging a rainwater entering a building through a joint portion of an outer wall panel surrounding the chimney in a building that houses a waste treatment facility having a chimney. And
The lower end of the outer wall panel is inserted into the groove of the grooved steel having a gradient in the width direction of the outer wall panel and the groove is directed upward, and the bottom surface of the outer wall panel and the groove shape A liner is interposed between the steel web surface.

In the present invention, the grooved steel is provided with a gradient in the width direction of the outer wall panel surrounding the chimney, the lower end portion of the outer wall panel is inserted into the grooved steel groove, and the outer wall panel is formed of the grooved steel. To support. At that time, since the channel steel has a gradient in the width direction of the outer wall panel, a liner is interposed between the bottom surface of the outer wall panel and the web surface of the channel steel, and the outer wall panel is supported via the liner. To do.
Rainwater flowing downward through the joint portion of the outer wall panel falls into the groove of the grooved steel that supports the outer wall panel. Rainwater that falls into the groove of the grooved steel flows in the groove toward the downstream side of the grooved steel, and is finally discharged outdoors.

Further, in the water leakage discharge structure according to the present invention, a horizontal draw rod is disposed below the channel steel, and the drain hole provided in the downstream portion of the channel steel web and the horizontal draw rod are connected by a rod. It is preferable that
In this configuration, the rain wall received by the channel steel is allowed to flow to the horizontal rod through the cage, so that the outer wall panel is not a single continuous channel steel but a plurality of discontinuous channel steels. Can be supported. That is, the grooved steel has only the function of collecting rainwater, and the drainage of the collected rainwater can be received by the horizontal draw rod. Thereby, the height difference of the grooved steel per piece can be reduced, and the original support function can be maintained.

In the water leakage discharge structure according to the present invention, the lower end portion of the outer wall panel is inserted into the groove of the grooved steel having a gradient in the width direction of the outer wall panel surrounding the chimney, and the outer wall panel is simply supported via the liner. By adopting a simple structure, rainwater that has entered the building through the joint portion of the outer wall panel can be discharged to the outside through the channel steel. That is, in the present invention, since the grooved steel that supports the lower end portion of the outer wall panel surrounding the chimney also has the function of a saddle, it is not necessary to replace the sealing material, and the cost can be reduced.
