However, in the case of fixing with bolts and nuts on the upper side of the outer wall panel as in the conventional fixing structure of the outer wall panel, when the pillar diameter becomes large as in a high-rise house or a rigid frame structure house, the bolts and nuts are used. There is a problem that it becomes difficult to insert a tool for fixing by the bolt between the back of the outer wall panel and the pillar.

In view of the above circumstances, the present invention provides a fixing structure for an outer wall panel capable of fixing the upper side of the outer wall panel without relying on bolt fixing.

In the fixing structure of the outer wall panel of the present invention, in order to solve the above-mentioned problems, a hook member having a neck portion and a head portion larger than the neck portion is provided on the upper side of the outer wall panel on the indoor side.
On the outdoor side of the pillar, a protruding support portion having a standing plate portion having a through hole into which the head can be inserted substantially horizontally is provided.
A stopper member having a main body portion larger than the through hole and a cut portion having a cut portion into which the neck portion enters with a width smaller than the head portion of the hook member inserted through the through hole on the indoor side of the standing plate portion. It is hooked on the neck by the cut
The protruding support portion has an opening on the upper surface thereof, and the stopping member is inserted through the opening to lock the hook member.

With the above configuration, the stopper member is hooked on the neck portion of the hook member inserted through the through hole on the indoor side of the standing plate portion, so that the stopper member moves in the out-of-plane direction on the upper side of the outer wall panel. Can be regulated by the hook member. That is, the upper side of the outer wall panel can be fixed without relying on bolt fixing.

A limiting portion that limits the upward movement of the stopping member may be provided. According to this, it is possible to prevent the stopper member from coming off.

The limiting portion may be located above the stopping member. The limiting portion may be made of a rod-shaped member fixed to a side surface portion of the protruding support portion.

The amount of upward movement of the stopping member limited by the limiting portion is preferably smaller than the amount of vertical movement allowed in the fastening structure on the lower side of the outer wall panel. According to this, even if the outer wall panel moves in the vertical direction due to the vibration caused by the earthquake, the outer wall panel does not come off.

A hook member having a neck portion and a head larger than the neck portion may be provided on the lower side of the outer wall panel on the indoor side, and a lower support portion for receiving the hook member may be provided on the building side. According to this, it is possible to reduce the cost by standardizing the parts using hook members on both the upper side and the lower side of the outer wall panel on the indoor side.

According to the present invention, various effects such as being able to fix the upper side of the outer wall panel without relying on bolt fixing can be obtained.

In the hook member 11, a washer 11c having a diameter larger than that of the head portion 11b is externally fitted and fixed to the neck portion 11a. Further, a lower support portion 3 is provided on the outdoor side surface on the lower side of the pillar 2. The lower support portion 3 has a semicircular recess 3a that receives the neck portion 11a of the hook member 11 from below. The lower side of the fixed structure 10 of the outer wall panel 1 is not limited to the lower support portion 3 having the semicircular recess 3a, and may be a structure that is inserted from above into a pin erected on the skeleton side. The panel fastening structure on the lower side is a structure in which the outer wall panel 1 can move upward with respect to the pillar 2 in the support on the lower side of the outer wall panel 1, and the outer wall panel 1 determines the allowable vertical movement amount in the fastening structure. If it moves upward beyond that, the lower side of the outer wall panel 1 may come off from the skeleton side.

Further, as shown in FIGS. 4 and 5, on the indoor upper side of the outer wall panel 1, a columnar neck portion 12a and a substantially disk-shaped head larger than the neck portion 12a are located on the tip end side of the neck portion 12a. A hook member 12 having 12b concentrically provided is provided. A washer is externally fitted and fixed to the hook member 12 as well as the hook member 11. A protruding support portion 4 is provided on the outdoor side surface on the upper side of the pillar 2.

As shown in FIG. 6, the protruding support portion 4 fixes only the standing plate portion 41 separated from the outdoor side surface of the pillar 2 and the upper center of the standing plate portion 41 to the outdoor side surface of the pillar 2. It is made of a steel plate including a plate portion 42 and a side plate portion 43 for fixing the side surface side of the standing plate portion 41 to the outdoor side surface of the pillar 2. The upper surface of the protruding support portion 4 has an opening at a portion other than the upper plate portion 42. Further, the side plate portion 43 is formed with a through hole through which a bolt is inserted.

Further, the standing plate portion 41 is formed with a circular through hole 41a into which the head portion 12b of the hook member 12 can be inserted substantially horizontally. When the upper side of the outer wall panel 1 is brought closer to the pillar 2 from the slanted state in which the hook member 11 on the lower side of the outer wall panel 1 is first received by the semicircular recess 3a, the head portion 12b of the hook member 12 is moved. It can be inserted into the through hole 41a.

Then, by hooking the stopper (stopping member) 5 on the neck portion 12a of the hook member 12 inserted from the through hole 41a on the indoor side of the standing plate portion 41, the upper portion of the outer wall panel 1 is raised. It is supported by the protruding support portion 4. The stopper 5 is inserted downward from the opening on the upper side of the protruding support portion 4. The left and right sides do not exist in the stopper 5.

The stopper 5 has a main body portion larger than the through hole 41a and a cut portion 5a into which the neck portion 12a enters with a width smaller than that of the head portion 12b. The plate thickness of the stopper 5 is substantially the same as the gap between the indoor surface of the standing plate 41 into which the stopper 5 is inserted and the surface of the head 12b on the neck 12a side, and has a fastening structure using bolts and nuts. The outer wall panel 1 can be fixed in the out-of-plane direction by the hook member 12 and the stopper 5 even if the outer wall panel 1 is not provided. Further, the stopper 5 has a bent side portion 5b at the upper portion.

Further, the fixed structure 10 includes a limiting portion 6 that limits the upward movement of the stopper 5. The limiting portion 6 is located above the stopper 5. Then, in this embodiment, the limiting portion 6 is composed of a rod-shaped member that is inserted into the through hole of the side plate portion 43 of the protruding support portion 4 and fixed to the side plate portion 43, and is composed of a long bolt and a nut. Will be done. Further, the amount of upward movement of the stopper 5 limited by the limiting portion 6 (the distance between the peripheral surface of the bolt portion of the limiting portion 6 and the bent side portion 5b) is the fastening structure on the lower side of the outer wall panel 1. It is smaller than the allowable vertical movement amount in. The limiting portion 6 is composed of a short bolt and a nut, the nut is provided in the through hole of the side plate portion 43, and the short bolt is placed above the bent side portion 5b from each of the side plate portions 43. It may be projected.

With the above configuration, the stopper 5 is hooked on the neck portion 12a of the hook member 12 inserted from the through hole 41a on the indoor side of the standing plate portion 41, so that the stopper 5 is hooked on the upper side of the outer wall panel 1. The movement in the out-of-plane direction can be regulated by the hook member 12. That is, the upper side of the outer wall panel 1 can be fixed without relying on bolt fixing.

If the limiting portion 6 for restricting the upward movement of the stopper 5 is provided, it is possible to prevent the stopper 5 from coming off. When the upward movement amount of the stopper 5 limited by the restriction portion 6 is smaller than the vertical allowable movement amount in the fastening structure on the lower side of the outer wall panel 1, it moves vertically to the outer wall panel 1 due to vibration caused by an earthquake. However, the outer wall panel 1 does not come off.

When the hook member 11 and the hook member 12 are provided, the cost can be reduced by standardizing the parts using the hook member on both the upper side and the lower side of the outer wall panel 1 on the indoor side.

Even if the stopper 5 is inserted into the protruding support portion 4 and the neck portion 12a is inserted into the cut portion 5a and the stopper 5 rotates around the neck portion 12a, this rotation still occurs. , The side plate portion 43 and the limiting portion 6 are blocked during rotation. Further, in order not to cause the rotation, for example, a convex portion may be formed on the stopper 5 and a hole portion with which the convex portion engages may be formed on the standing plate portion 41.
