Embodiment An embodiment of the present invention will be described below with reference to FIGS. 13, those parts which are the same as those corresponding parts in FIG. 13 are designated by the same reference numerals. The wall panel 1 is mainly composed of a shallow box-shaped metal panel in which an upper bent piece 3a, a side bent piece 3b, and a lower bent piece 3c are continuously arranged on four sides of a main plate 2. An upward bending piece portion 11 is continuously provided at the tip of the upper bending piece portion 3a. A backing material 8 made of a refractory material adhered to the back surface of the main plate portion 2 is provided as needed.

On the other hand, 10A is a vertical base material, which is vertically arranged continuously inside the vertical joint 7A and is fixed to the building frame through a connecting member such as an anchor (not shown). Further, 10B is a horizontal base material, which is connected to the vertical joints 7A in a grid pattern, is arranged inside the horizontal joints 7B, and is fixed to the building frame through a connecting member such as an anchor (not shown). There is.

In the wall panel 1, the clip 4 fixed to the side bent piece portion 3b is fixed to the vertical base material 10A by the tap pin screw 5, and the upper bent piece portion 11 is fixed to the horizontal base material 10B. The clip 4 fixed by the screw 5 and fixed to the lower bent piece portion 3c is fixed to the lateral base material 10B together with the upper bent piece portion 11 by the tat pin screw 5, so that the clip 4 is attached to the building frame.

In this embodiment, in order to avoid interference with a rainwater receiver 30 described later, a cutout 12 is provided in the lower corner of the wall panel 1 as shown in FIG. An outer fitting portion 13 having an L-shaped cross section is provided. Further, as shown in FIG. 10, an inner fitting portion 14 having an L-shaped cross section for similarly positioning the rainwater receiver 30 is provided at the upper corner of the wall panel 1.

On the other hand, reference numeral 20 denotes a rubber gasket, and as shown in FIGS. 2 and 5, a seal portion 21 having a lip 21a for a seal and an outer surface 21b of the seal portion 21 are spaced from each other. The stopper piece portion 22 is opposed to the stopper piece portion 22, and the connecting piece portion 23 connects the stopper piece portion 22 and the seal portion 21. This gasket 20 is cut into lengths close to the four sides of the wall panel 1, and the gaps between the side bent pieces 3b and 3b of the adjacent wall panels 1 and between the upper bent pieces 3a and the lower bent pieces 3a are cut. The seal portion 21 is inserted between the piece portion 3c and the inside portion (building side).

Reference numeral 30 denotes a rainwater receiver made of a rubber molded product. As shown in FIG. 10, a side wall 32 and a front wall 33 of a box-shaped container portion 31 that opens upward are extended downward to have a flat cross section. A leg portion 34 having a flat U-shape is formed, and on the outer surface of the leg portion 34, stopper pieces 35 and 36 functioning as stoppers for the back-up material 9 used for filling the sealing material are provided in a protruding manner, and a container is formed. A drain portion 37 is formed by cutting out a central portion of the front wall 33 of the portion 31.

As shown in FIGS. 10 and 11, the rainwater receiver 30 includes a gasket 20 in which upper ends of the stopper piece portion 22 and the connecting piece portion 23 are cut out in order to avoid interference with the rainwater receptacle 30. After being inserted between the side bent piece portions 3b, 3b of the adjacent wall panels 1, it is placed on the upper bent piece portion 3a of the wall panel 1 so as to be fitted into the inner fitting portions 14, 14. Then, when the upper wall panel 1 is attached to the building frame, the outer fitting portion 13 at the lower end of the wall panel is fitted to the outer circumference of the rainwater receiver 30 so that the rainwater receiver 30 can be installed vertically on the lower portion of the wall panel 1. It is attached near the intersection of joint 7A and side joint 7B.

As a result, the container portion 31 of the rainwater receiver 30 faces the lower end surface of the vertically extending gasket 20 and the lower end surface of the notch 12 of the side bent piece 3b that holds the gasket 20. And is positioned so as to open upward.

When the sealing material 6 for the seal between the bent pieces of the wall panel 1 is filled, the gasket 20 is inserted and the backup material 9 is inserted after the rainwater receiver 30 is attached. The back-up member 9 is easily linearly positioned by the piece 22 and the stopper pieces 35 and 36 of the rainwater receiver 30. By filling the sealing material 6 on this, the vertical joints 7A and the horizontal joints 7B can be formed quickly and easily, and at the same time, the sealing portion 21 of the gasket 20 and the sealing material 6 (see this embodiment). When the back up material 9 is used, the rain water flow passage 40A extending in the up and down direction and the rain water extending in the left and right direction are defined by the bent piece of the wall panel 1 between the back up material 9 and the back up material 9). The flow path 40B is formed.

In the rain-sealing structure having the above-described structure, when the sealing material is broken at the vertical joint 7A, the rainwater that has entered the inside of the sealing material-filled portion is sealed by the sealing portion 21 of the gasket 20. Therefore, it is prevented from invading further inward, flows down in the rainwater flow path 40A along the side bent pieces 3b, etc., and sequentially flows down in the rainwater flow path 40A between the wall panels 1 on the lower side. , Is drained from the lower part of the bottommost wall panel 1 to a drainage ditch or the like. For this drainage, the lower end portion of the vertical joint 7A of the lowermost wall panel 1 may be cut out or a drain hole communicating with the rainwater flow passage 40A may be formed near the lower end portion.

Further, the rainwater flowing down in the rainwater flow path 40A enters the seal portion 21 of the gasket 20 or further into the seal portion 21, and the side bent piece portion 3b and the seal portion 21b. When the rainwater flows down along the channel portion 21, the rainwater drops into the rainwater receiver 30 and is returned from the drainage port 37 into the rainwater flow path 40A to prevent it from entering the building side.

Even when the sealing material runs out at the lateral joint 7B, the rainwater that has entered the inside of the sealing material filled portion further enters inside by the seal portion 21 of the gasket 20. Of the rainwater flow path 40B, flows in the rainwater flow path 40B in the left-right direction along the upper bent piece portion 3a, and then flows into the rainwater flow path 40A from the upper corner of the wall panel 1 and is carried out in the same manner as above. It flows down in 40A and is drained.

Further, even if rainwater flowing in the rainwater flow path 40B invades inside beyond the seal portion 21 of the gasket 20, the upper bent piece portion 11 surely prevents the rainwater from entering the building side. However, rainwater flows left and right on the upper bent piece 3a in the same manner as described above and is guided into the rainwater flow passage 40B.

The present invention is not limited to the above embodiment, and for example, the specific cross-sectional shape of the gasket 20 may be other than the above. Further, as shown in FIG. 12, the rainwater receiver 30 may be one in which the stopper pieces 35, 36 (see FIG. 10) are omitted, and when the projection 38 for positioning is provided, the wall panel 1 is fitted internally. The portion 14 (see FIG. 10) and the outer fitting portion 13 (see FIG. 11) may be omitted.

Further, the upper bent piece portion 11 of the wall panel 1 may be omitted, and in this case, if the leg portion 34 of the rainwater receiver 30 is shortened to a height that does not interfere with the upper wall panel 1, the wall panel 1 It is also possible to omit the lower notch 12 of 1.

Further, particularly when the upper bent piece portion 11 is provided, or when the sealing material running out of the lateral joint portion is dealt with by other means, the upper bent piece portion 3a of the wall panel 1 and The gasket 20 may not be inserted between the lower bent piece portions 3c, and the sealing may be performed only by filling the sealing material 6 by a conventional method.
