2. Description of the Related Art As shown in FIG. 5, a plurality of precast concrete panels 8 and 8 used for forming an outer wall of a concrete building are provided with vertical joints 9a and horizontal joints 9b which are adjacent to each other. The irregular waterproof material 17 is packed in the portion. When installing the window 10 in the space secured between the precast concrete panels 8 forming the outer wall, the metal window frame 10a is attached along the left and right vertical joints 9a (only the left side in the figure). The metal window frame 10a is the lower precast concrete panel 8A.
Between the upper end surface 8a of the precast concrete panel 8B and the lower end surface 8b of the upper precast concrete panel 8B, and the vertical joints 9 of the left and right precast concrete panels 8C (only the left side is shown).
The side window frame 11 is inserted into the space surrounded by the side end surface corresponding to a together with the vertically extending side window frame 11 made of metal.
Rectangular rubber-like blocking members 30 and 30 as shown in FIG. 13 are inserted in the upper and lower portions of the above, and are arranged on the upper end surface 11b in the state as shown in FIG. 12, for example. After that, metal window frame 1
0a and the upper end surface 8a of the precast concrete panel 8A and the precast concrete panel 8
An irregular waterproof material 10b is packed between the lower end surface 8b of B and the side window frame 11. As shown in FIG. 6, a step surface having a height difference is formed on the upper end surface 8a of the precast concrete panel 8A in the direction Q from the room M to the room N of the building. On the other hand, a height difference in the direction Q is also provided on the lower end surface 11a of the side window frame 11. A similar height difference is formed on the lower end surface 8b of the precast concrete panel 8B and the upper end surface 11b of the side window frame 11 in the direction Q from the room M to the room N. As shown in FIG. 5, the window 10 is formed by fitting the metal window frame 10a and the side window frame 11 between the end surfaces 8a and 8b of the precast concrete panels 8A and 8B. The end faces 11a and 11b of the partial window frame 11 act so as to compress the respective blocking members 30 and 30. The lower blocking member 30 is deformed in the gap formed by the upper end surface 8a of the precast concrete panel 8A and the lower end surface 11a of the side window frame 11, and the upper blocking member 30 is changed to the precast concrete panel 8A.
It deforms in the gap formed by the lower end surface 8b of B and the upper end surface 11b of the side window frame 11. As a result, the water stopping action is exerted at the upper and lower portions of the side window frame 11.

[0003]

By the way, the blocking material 30 which has been conventionally used is formed by molding chloroprene rubber, urethane sponge or the like into a plate shape (FIG. 13).
reference). The chloroprene rubber has the advantage of having waterproof performance. However, since the material is hard, it lacks flexibility and does not fit well with the steps formed on the upper and lower surfaces of the precast concrete panel. Moreover, even if it deforms in the gap, it may not sufficiently adhere to the end faces of the precast concrete panel or the side window frame that have steps, which may cause water leakage and function as a water blocking material. There is a problem that damages. Furthermore, since the closing material lacks flexibility, when the metal window frame is attached to the outer wall together with the side window frame, it becomes difficult to absorb the gap error between the metal window frame and the precast concrete panel caused by the assembly error or the like. However, there is also a drawback that it hinders the installation work of the window, and that it takes time and effort to correct it. On the other hand, the urethane sponge blocker fits well and adheres well to the end faces of the precast concrete panel and the side window frame in the sandwiched gap. However, since it lacks waterproofness, there is a drawback that the packing function as a water blocking material is insufficient, and improvement thereof is desired. Furthermore, as shown in FIG.
Although the rain barrier 6 is provided inside the vertical joint 9a,
In order to be able to install it, it is necessary to provide cutouts 13a, 13b in the facing portion between the precast concrete panels 8A, 8B and the precast concrete panel 8C. However, the conventional sealing material 3
No. 0 has a plate shape as shown in FIG. 13, and no cutout is formed therein. Therefore, it is necessary to provide the cutout 5 in a physical manner at the installation site of the metal window frame. As a result, there is a problem that it takes time and labor to install the metal window frame between the precast concrete panels. The present invention has been made in view of the above problems, and an object thereof is to use a sealing material as a water blocking material that has high waterproofness and familiarity and can be consolidated by deformation, and the end face of a side window frame and precast. In order to make it easier to fill the gap with the end surface of the concrete panel, the shape is adapted to the shape of the end surface to improve the adhesiveness, and the rain barrier provided in the vertical joint can be easily installed. Along with the vertical joints of the precast concrete outer wall, which enables the efficiency of the construction work by making it possible to eliminate the need to form notches one by one at the site where the metal window frame is mounted.

EFFECTS OF THE INVENTION According to the present invention, since the sealing material is made of EPDM rubber, it is excellent in waterproofness and compaction, and matches the gap between the end face of the side window frame and the end face of the precast concrete panel. Since the upper and lower steps are molded so as to have a height difference, when they are sandwiched in the gap formed by the end surface of the precast concrete panel and the end surface of the side window frame, they fully adhere to both end surfaces. At the same time, the adhesiveness there is also improved, and the waterproofness of the outer wall is remarkably enhanced without causing water leakage or the like. At the time of molding the blocking material, since the notch opening to the vertical joint side is formed in the lower step portion of the blocking material in advance, it is possible to install a rain barrier along the vertical joint and to install the side window frame. At the time of mounting, it is possible to save the labor of making notches in the closing material one by one and improve the construction efficiency. In addition, the blocking material with excellent compressibility can easily absorb the gap error by consolidating the easily deformable blocking material even if errors occur due to various causes when mounting the side window frame. And the exterior appearance is also beautiful.
