However, when fixing the upper part of the exterior wall panel with bolts and nuts, as in the conventional exterior wall panel fixing structure described above, when the column dimensions become large, such as in high-rise houses and rigid frame houses, the bolts and nuts It becomes difficult to insert the fixing tool between the back of the exterior wall panel and the pillar.

In view of the above circumstances, the present invention provides an exterior wall panel fixing structure that allows the upper side of the exterior wall panel to be easily fixed to the column even if the column size is large.

In order to solve the above-mentioned problems, the fixing structure for an exterior wall panel of the present invention is a fixing structure for an exterior wall panel including a vertical frame member and a horizontal frame member, wherein the upper corner of the exterior wall panel is attached to the outdoor surface of a column. A first fixing part of a panel joining member facing each other and joining the outer wall panel to the pillar is fixed to the upper corner part, and a side part of the upper side of the outer wall panel is fixed from the first fixing part of the panel joining member to the upper side of the outer wall panel. The second fixing portion, which is spaced apart in the horizontal direction along the frame member, is fixed to the lateral portion of a column-side fixing member having a lateral portion located on the lateral side of the column.

With the above configuration, the second fixing part located horizontally apart from the first fixing part of the panel joining member along the horizontal frame member on the upper side of the outer wall panel is fixed to the column side. Since it is only necessary to fix it to the above-mentioned lateral portion of the member, the upper side of the outer wall panel can be easily fixed to the column side even if the column size is large.

The panel joining member may be provided with a right angle maintaining portion that maintains a right angle state in which the vertical frame member and the horizontal frame member are fitted to each other. According to this, the right angle between the vertical frame member and the horizontal frame member is maintained, so even if the vertical frame member attempts to move upward due to an earthquake, this upward movement is suppressed. Therefore, even if the lower side of the outer wall panel is fixed in such a way that the outer wall panel may move upward, the lower side of the outer wall panel cannot be detached from the frame by exceeding the allowable amount of upward movement. It can be prevented.

The right angle maintaining portion may be located on an outer side of the vertical frame member so as to be able to come into contact with it. In addition to this, or in place of this, the right angle maintaining portion may be located so as to be able to come into contact with an inner edge of the vertical frame member that does not interfere with the horizontal frame member.

The pillar-side fixing member may be provided with a regulating portion that regulates upward movement of the vertical frame member. According to this, even if the vertical frame member moves upward in a way that the panel joint member cannot withstand due to a large earthquake, the upward movement of the vertical frame member can be restricted by the regulating portion.

The regulating portion may protrude toward the outdoors and may be located above an indoor-side portion of the fastening member provided at the first fixing portion of the panel joining member. According to this, upward movement of the vertical frame member can be restricted via the fastening member provided on the first fixing portion.

The present invention provides various effects such as being able to easily fix the upper side of the outer wall panel to the column even if the column size is large.

A hook member 11 is provided concentrically with a generally disk-shaped head portion 11b that is larger than the neck portion 11a. In addition, in the hook member 11, a washer 11c having a larger diameter than the head 11b is externally fitted and fixed to the neck 11a. Further, a lower support part 3 is provided on the outdoor side surface of the lower part of the pillar 2. This lower support portion 3 has a semicircular recess 3a that receives the hook member 11 from below. The lower part of the fixing structure 10 of the outer wall panel 1 is not limited to the lower support part 3 having the semicircular recess 3a, but may have a structure in which it is inserted from above into a pin erected on the frame side. These panel fastening structures on the lower side are such that when supporting the lower side of the outer wall panel 1, upward movement of the outer wall panel 1 with respect to the pillars 2 can occur, and the outer wall panel 1 has a structure that allows the outer wall panel 1 to move within the permissible vertical movement in the fastening structure. If the outer wall panel 1 is moved upwardly, there is a risk that the lower part of the outer wall panel 1 may come off from the frame.

Further, for example, the outer wall panel 1 includes a vertical frame member 111 and a horizontal frame member 112 made of steel and having a substantially U-shaped cross section. Further, for example, both ends of the horizontal frame member 112 are squeezed and fitted into the vertical frame member 111.

Further, as shown in FIGS. 4 and 5, the upper corner portion of the exterior wall panel 1 on the indoor side is located facing the outdoor surface of the pillar 2. A first fixing part 41 of a panel joining member 4 for joining the outside wall panel 1 to the pillar 2 is fixed to the upper corner of the outside wall panel 1 by bolts and nuts 6 that are fastening members. . The panel joining member 4 is obtained by, for example, bending a steel plate, making holes, forming ribs, forming embossing, welding, and the like.

The panel joining member 4 has a laterally elongated shape and is arranged so as to extend horizontally along the horizontal frame member 112 on the upper side of the outer wall panel 1. The panel joining member 4 is provided with a second fixing part 42 at a position spaced apart from the first fixing part 41 in the horizontal direction along the horizontal frame member 112 on the upper side. This second fixing portion 42 is obtained, for example, by forming a through hole and welding a nut. A stepped portion is formed between the second fixing part 42 and the first fixing part 41, and the second fixing part 42 is located closer to the indoor side than the first fixing part 41.

Further, a column-side fixing member 5 is welded and fixed to the column 2 in advance on the outdoor surface side and the side surface side of the column 2. Further, the column-side fixing member 5 is made of, for example, a steel plate, and has a welding target portion, a reinforcing portion, etc. formed by bending. A vertical plate portion (horizontal portion) 51 of the column-side fixing member 5 extending laterally from the outdoor surface of the column 2 has a bolt insertion hole 51a formed in the horizontal direction. As shown in FIG. 6, a bolt 52 inserted into the bolt insertion hole 51a from the indoor side is screwed into the second fixing part 42 of the panel joining member 4.

That is, the upper corner portion of the outer wall panel 1 is fixed to the column-side fixing member 5 at a position laterally away from the outdoor surface of the column 2 via the panel joining member 4, and the column-side fixing member 5 It is fixed to the pillar 2 through. In this way, the second fixing portion 42 of the panel joining member 4 can be fixed to the column-side fixing member 5 at a position laterally removed from the outdoor surface of the column 2, so that the column of the column 2 can be Even if the size is large, the upper side of the outer wall panel 1 can be easily fixed to the pillar side.

Here, the upper corner of the outer wall panel 1 is not directly fixed to the pillar 2, but is attached to the pillar-side fixing member 5 at a position laterally shifted from the upper corner via the panel joining member 4. If it is fixed, it becomes difficult to suppress upward movement of the vertical frame member 111. That is, it becomes difficult to maintain the perpendicular state when the vertical frame member 111 and the horizontal frame member 112 are fitted into each other. In this embodiment, as shown in FIGS. 7(A) and 7(B), the panel joining member 4 maintains a right angle state when the vertical frame member 111 and the horizontal frame member 112 are fitted into each other. A right angle maintaining section 43 is provided. The right angle maintaining section 43 includes a right angle maintaining section 43A that is positioned so as to be able to come into contact with the outer side of the vertical frame member 111. This right angle maintaining portion 43A is formed by bending a steel plate constituting the panel joint member 4, and is bent at 90 degrees from the indoor side of the vertical frame member 111 to the outer side of the vertical frame member 111. The tip side of the outer part faces outdoors.

Further, the panel joining member 4 serves as the right angle maintaining part 43 that maintains the right angle between the vertical frame member 111 and the horizontal frame member 112, and is arranged below the horizontal frame member 112 so as not to interfere with the horizontal frame member 112. and a right angle maintaining part 43B located above so as to be able to come into contact with the inner edge of the vertical frame member 111. This right angle maintaining portion 43B is formed by bending a steel plate constituting the panel joining member 4, and extends at 90 degrees from the indoor surface side of the vertical frame member 111 to the vicinity of the inner edge of the vertical frame member 111. It is bent with the tip facing outdoors. In the example shown in FIG. 6, of the two right angle maintaining sections 43B located above and below, only the lower right angle maintaining section 43B acts to maintain the right angle. However, if the two right angle maintaining parts 43B located above and below are provided in this way, the panel joining member 4 can be used as a common item for both the left and right sides.

When the right angle maintaining portions 43 (43A, 43B) are provided, the right angle between the vertical frame member 111 and the horizontal frame member 112 is maintained, so even if the vertical frame member 111 attempts to move upward due to an earthquake, Furthermore, movement is suppressed. Therefore, even if the lower part of the outer wall panel 1 is fixed in such a way that the outer wall panel 1 may move upward, the lower part of the outer wall panel 1 may separate from the frame by exceeding the allowable amount of upward movement. You can prevent it from happening. Note that instead of having both of the right angle maintaining portions 43A and 43B, a configuration may be adopted in which only one of the right angle maintaining portions 43A and 43B is provided.
