TECHNICAL FIELD OF THE INVENTION
The present invention relates to an outer wall panel and a vertical joint water stopping structure between the outer wall panels.
[0002]
[Prior art and problems]
As a method of mounting the outer wall material, a surface material holding metal is used, and the outer wall material is mounted on the site so that the edge of the outer wall material is held by the surface material holding metal. .
[0003]
However, there is a problem that it is difficult to improve the quality and precision of the mounting in the mounting of the outer wall material on site using the surface material holding metal.

The outer wall material is held by the panel frame with its upper and lower edges engaged and held by the face material holding hardware, and
Side slip prevention hardware is attached to each of the left and right sides of the panel frame, and the side slip prevention metal extends along the side surface from the back side of the outer wall material, and regulates the lateral slip of the outer wall material at a portion along the side surface portion. The problem is solved by an outer wall panel characterized by being provided.
[0006]
In this way, since the outer wall material is attached using the surface material holding hardware, but the attachment is performed in the outer wall panel, it is not necessary to attach the outer wall material on site, The outer wall material can be attached at a place where the outer wall panel is manufactured, such as in a factory, and the quality and accuracy of the attachment of the outer wall material can be improved.
[0007]
Moreover, lateral displacement prevention hardware is attached to each of the left and right sides of the panel frame, and the lateral displacement prevention hardware extends along the side surface from the back side of the outer wall material, and regulates lateral displacement of the outer wall material at a portion along the side surface portion. The outer wall material is displaced with respect to the panel frame when transporting or building the outer wall panel, even though the outer wall material is held on the panel frame by the surface material holding hardware. Therefore, the outer wall panel can be attached to the building with good quality and high accuracy by constructing the outer wall panel.
[0008]
Also, the adjacent left and right outer wall panels are composed of the above outer wall panels,
In the portion between these outer wall panels, one or both of the lateral displacement prevention hardware of the left and right outer wall panels includes a portion serving as a base of a vertical joint between adjacent left and right outer wall materials, and the portion is used as a backup portion to be a neighboring portion. The present invention is also similarly solved by a vertical joint water-stop structure between outer wall panels, in which a primary water-stop material is provided between matching left and right outer wall materials. In addition, this water-stop structure has a function as a back-up part of the primary water-stop material between the left and right outer wall materials, and the primary water-stop material has a simple structure and construction. In addition to being able to be easily provided between the left and right outer wall materials, the outer wall material can be attached to the building side with good quality and high accuracy with a simple structure.

The outer wall material 1 is attached to the left and right vertical panel frames 3 and 3 with screws 4 and the like, and the upper and lower edges of the outer wall material 1 are held by the surface material holding hardware 2 to form an outer wall panel 5. In the present embodiment, although not shown in detail, the outer wall material 1 is composed of a plurality of face materials arranged in a vertically adjacent state, and the upper and lower edges of each face material hold the face material. The structure is held by hardware 2.
[0011]
Then, in each of the left and right vertical panel frames 3, 3, the lateral slip prevention hardware 6, 6 is attached with the screw 4 or the like so as to be sandwiched between the vertical panel frame 3 and the face material holding hardware 2. The metal fittings 6, 6 extend from the rear side of the outer wall material 1 so as to bend along the side surface, and a portion 6a along the side surface engages with the side surface of the outer wall material 1 so that the lateral wall material 1 is shifted laterally. It is equipped to regulate. Further, as shown in FIGS. 3 and 4, a portion 6 b serving as a base of a vertical joint 7 between the outer wall materials 1, 1 of the adjacent outer wall panels 5, 5 is integrally formed on one of the left and right lateral displacement prevention hardware 6. It is prepared for.
[0012]
The outer wall panel 1 is attached to a building by manufacturing the outer wall panel 5 in a factory or the like, transporting it to the site, and constructing the outer wall panel 5 on the site.
[0013]
As described above, since the outer wall material 1 is mounted using the surface material holding hardware 2 and 2 and the mounting is performed in the outer wall panel 5, the quality of the mounting of the outer wall material 1 is improved. High accuracy can be achieved.
[0014]
Moreover, the lateral displacement prevention metal fittings 6, 6 attached to the left and right vertical panel frames 3, 3 restrict lateral displacement of the outer wall material 1 in either the left or right direction by the portion 6a along the side surface of the outer wall material 1. As a result, the outer wall material 1 is held on the panel frames 3 and 3 by the surface material holding hardware 2 and 2 while the outer wall panel 5 is transported or erected. The wall material 1 is not displaced in the lateral direction with respect to the panel frames 3, 3. Therefore, only by constructing the outer wall panel 5, the outer wall material 1 can be constructed with good quality and high accuracy. Can be mounted on the side.
[0015]
After finishing the construction of the outer wall panel 5 in this way, as shown in FIG. 4, a portion 6 b to be a longitudinal underground ground of the lateral displacement prevention hardware 6 is provided in the longitudinal joint 7 between the adjacent left and right outer wall materials 1, 1 Is used as a backup unit, and is filled with a wet sealing material 8 as a primary water-stopping material. In this way, the primary waterproofing material 8 has a simple structure and is easy to construct by providing the lateral displacement preventing hardware 6 with a function as a backup portion of the primary waterproofing material 8 between the left and right outer wall materials 1 and 1. Can be provided between the left and right outer wall materials 1 and 1, and the outer wall material 1 can be transported with a simple structure while maintaining quality and accuracy, and can be attached to the building side with good quality and accuracy. .
[0016]
The second embodiment shown in FIGS. 5 to 8 uses a dry gasket 9 as a primary water-stopping material to stop water between the outer wall materials 1, 1. Both of the metal members 6 and 6 for preventing lateral displacement have portions 6b and 6b serving as bases of vertical joints 7 between the adjacent left and right outer wall materials 1 and 1 to enhance the water stopping effect of the gasket 9. For this reason, the portions 6b, 6b serving as the vertical joint basement of the lateral displacement prevention hardware 6, 6 are provided so as to be located deeper and deeper than the vertical joint 7. In addition, the portion 6 a along the side surface of the lateral displacement prevention metal fitting 6 may be adhered to the side surface of the outer wall material 5 in a water-stop state. Others are substantially the same as the first embodiment.
[0017]
Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various changes can be made without departing from the spirit of the invention. For example, in the above-described embodiment, a description has been given of an example in which the portion 6b serving as a vertical underground ground is integrally provided in the lateral slip prevention hardware 6, but a portion serving as a vertical ground underground is removed from the side slip prevention hardware 6; The backup portion for the primary water-stopping material may be formed by installing a backup material on the vertical joint 7 separately from the lateral displacement prevention hardware 6.
