Description

The present invention relates to a fixed structure of an outer wall panel that attaches the outer wall panel to the outside of the building frame.

Patent Document 1 discloses a fixing structure of an outer wall panel so that the upper side of the outer wall panel can be fixed by bolts and nuts and can be hooked and fixed on the lower side of the outer wall panel.

Japanese Unexamined Patent Publication No. 2016-102338

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 side surface, and the stopping member is inserted into the opening from the side.

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. Further, even when the structure or the like is located above the protruding support portion, the stopping member can be easily inserted and mounted from the side.

The stopper member inserted through the opening may be rotated approximately 90 degrees around the neck. According to this, the entrance of the cut portion can be positioned on the lower side by the rotation.

A lock portion that restricts the movement of the stopper member may be provided with the neck portion inserted into the cut portion of the stopper member. According to this, it is possible to prevent the stopper member from coming off.

The lock portion may be provided integrally with the stopper member. According to this, the handling of the lock portion and the stopper member becomes easier as compared with the structure in which the lock portion is separate from the stopper member.

The lock portion may engage with the protruding support portion. According to this, the structure of the lock portion can be simplified as compared with engaging the lock portion with, for example, the hook member side.

The distance between the stopper member and the upper plate located above the protruding support portion is preferably smaller than the vertical allowable movement amount 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.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1, 2 and 3, in the fixed structure 10 of the outer wall panel 1 of this embodiment, the cylindrical neck portion 11a and the tip end side of the neck portion 11a are on the lower side of the outer wall panel 1 on the indoor side. Is provided with a hook member 11 having a substantially disk-shaped head portion 11b larger than the neck portion 11a concentrically provided therein. 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. 8, the projecting support portion 4 includes a standing plate portion 41 that is separated from the outdoor side surface of the pillar 2, and an upper plate portion that fixes the upper portion of the standing plate portion 41 to the outdoor side surface of the pillar 2. The cross section including the 42 and the lower plate portion 43 for fixing the lower portion of the standing plate portion 41 to the outdoor side surface of the pillar 2 is made of a substantially U-shaped steel plate. The protruding support portion 4 has an opening on the side surface.

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. As shown in FIGS. 6A and 6B, the stopper 5 has left and right sides, and is inserted into the openings on the left and right side surfaces of the protrusion support portion 4 from the side. That is, even when the structure or the like is located above the protruding support portion 4, the stopper 5 can be easily inserted and mounted from the side.

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, as shown in FIG. 7, the stopper 5 is integrally provided with a lock portion 51 in the main body portion thereof. The lock portion 51 limits the movement (rotation) of the stopper 5 in a state where the neck 12a is inserted into the cut portion 5a of the stopper 5. In this example, as shown in FIG. 9, in a posture in which the entrance of the cut portion 5a faces sideways, the lock portion 51 is placed at a lower angle located outside the protruding support portion 4 in the main body portion of the stopper 5. Be prepared. The stopper 5 is inserted into the openings on the left and right side surfaces of the protruding support portion 4 from the side, and is rotated upward by approximately 90 degrees around the neck portion 12a, so that the lock portion 51 becomes the standing plate portion 41. Is locked to the above, and the stopper 5 is attached. When the inlet of the cut portion 5a is located on the lower side and the outer wall panel 1 (hook member 12) moves upward in the mounted state of the stopper 5 by rotating 90 degrees, the main body of the stopper 5 The upper edge of the portion is in contact with the lower surface of the upper plate portion 42. In a posture in which the inlet of the cut portion 5a faces sideways, the upper angle of the main body of the stopper 5 located outside the protruding support portion 4 is the upper plate portion of the protruding support portion 4 during rotation. It is chamfered in an arc shape so as to avoid interference with 42.

The lock portion 51 forms a holding portion by facing the main body portion of the stopper 5, and the holding portion sandwiches and locks the standing plate portion 41 from the front and back. This lock prevents the return rotation of the stopper 5. Further, the lock portion 51 is formed with a curved portion 51a that is caught on the surface side of the standing plate portion 41 in the sandwiched state. The curved portion 51a more reliably prevents the return rotation of the stopper 5.

In the mounted state of the stopper 5 by rotating 90 degrees, the distance between the upper edge of the main body of the stopper 5 and the upper plate 42 of the protruding support 4 is the lower part of the outer wall panel 1 on the indoor side. It is smaller than the vertical allowable movement amount in the side fastening structure. As a result, the hook member 11 is prevented from being separated from the semicircular recess 3a when the outer wall panel 1 is moved upward during an earthquake.

Further, if the hook member 11 is also provided on the lower side of the outer wall panel 1 on the indoor side, it is possible to standardize the parts by the hook member 11 and the hook member 12, and the cost can be reduced.

Next, other embodiments will be described with reference to FIGS. 10 to 15, but the same elements as those in the above embodiments will be designated by the same reference numerals and the description thereof will be omitted.

As shown in FIGS. 10 and 11, the fixing structure of the outer wall panel of this embodiment includes a protruding support portion 4A that functions in the same manner as the protruding support portion 4, and a stopper 5A that functions in the same manner as the stopper 5. .. As shown in FIG. 14, the vertical plate portion 41 of the protruding support portion 4A has a circular locking hole 41b formed above the through hole 41a and on the vertical center line of the through hole 41a. .. On the other hand, the stopper 5A has a vertically symmetrical structure when attached to the hook member 12, and as shown in FIGS. 12 and 13, the above-mentioned engagement is performed at the position above the cut portion 5a. A hemispherical convex lock portion 51A that engages with the stop hole 41b is provided. In the stopper 5A, there is no left or right. The stopper 5A is formed with vertical side portions 5b on both sides of the main body portion, and it is possible to hit the vertical side portions 5b by hitting a rod-shaped member.

As shown in FIG. 15, the stopper 5A is inserted into the openings on the left and right side surfaces of the protruding support portion 4A from the side, and is rotated upward by approximately 90 degrees around the neck portion 12a to be in the mounted state. Further, the locking portion 51A is held by the protruding support portion 4A by engaging with the locking hole 41b. As a result, the return rotation of the stopper 5A is prevented.

Further, in a state where the stopper 5A is rotated about 90 degrees around the neck 12a, the distance between the upper edge of the main body of the stopper 5A and the upper plate 42 of the protrusion support 4A is as described above. It is made smaller than the allowable vertical movement amount in the fastening structure on the lower side of the outer wall panel 1 on the indoor side. If the locking hole 41b is a long hole that is long in the vertical direction, the locking will not be easily released even if the stopper 5A is moved upward by the upward movement of the outer wall panel 1.

Further, other embodiments will be described with reference to FIGS. 16 to 21, but the same elements as those in the above embodiment are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIGS. 16 and 17, the fixing structure of the outer wall panel of this embodiment includes a protruding support portion 4B that functions in the same manner as the protruding support portion 4, and a stopper 5B that functions in the same manner as the stopper 5. .. As shown in FIG. 20, a locking hole 42c is formed in the upper plate portion 42 of the protruding support portion 4B. On the other hand, the stopper 5B is a spring material provided with a convex portion that engages with the locking hole 42c at a position above the cut portion 5a in a state of being attached to the hook member 12, as shown in FIGS. 18 and 19. A lock portion 51B including the lock portion 51B is provided. The stopper 5B has left and right sides. Further, the lock portion 51B made of the spring material is welded and fixed to the stopper 5B.

The stopper 5B is inserted into the openings on the left and right sides of the protruding support portion 4B from the side, and is rotated upward by approximately 90 degrees around the neck portion 12a to be in the mounted state, and the lock portion 51B is convex. The shaped portion engages with the locking hole 42c and is held by the protruding support portion 4B. As a result, the return rotation of the stopper 5B is prevented.

Further, in a state where the stopper 5B is rotated about 90 degrees around the neck 12a, the distance between the upper edge of the main body of the stopper 5B and the upper plate 42 of the protrusion support 4B is as described above. It is made smaller than the allowable vertical movement amount in the fastening structure on the lower side of the outer wall panel 1 on the indoor side. Since the lock portion 51B is made of a spring material and can be bent up and down, even if the stopper 5B is moved upward by the upward movement of the outer wall panel 1, the lock in the lock portion 51B is not easily released.

Further, another embodiment will be described with reference to FIG. 22, but the same elements as those in the above embodiment are designated by the same reference numerals and the description thereof will be omitted.

The fixing structure of the outer wall panel of this embodiment includes a protruding support portion 4C that functions in the same manner as the protruding support portion 4, and a stopper 5C that functions in the same manner as the stopper 5. In the standing plate portion 41 of the protruding support portion 4C, a circular locking hole 41d is formed on, for example, the horizontal center line of the through hole 41a. On the other hand, the stopper 5C includes a hemispherical convex lock portion 51C that engages with the locking hole 41d at a lateral position of the cut portion 5a when attached to the hook member 12. The stopper 5C does not have left and right sides.

The stopper 5C is inserted into the openings on the left and right side surfaces of the protruding support portion 4C from the side, and is slid to be in the mounted state. The lock portion 51C engages with the locking hole 41d to support the protrusion. It is held by the part 4C. As a result, the return slide and rotation of the stopper 5A are prevented. If the stopper 5C is provided with a bent portion 52 bent 90 degrees from the main body portion, the stopper 5C can be slid by hitting the bent portion 52.

Further, in the mounted state of the stopper 5C, the distance between the upper edge of the main body of the stopper 5C and the upper plate 42 of the protrusion support 4C is the lower side of the outer wall panel 1 on the indoor side. It is made smaller than the allowable vertical movement amount in the fastening structure. When the outer wall panel 1 moves upward, the stopper 5C can rotate around the lock portion 51C, so that the lock in the lock portion 51C is hard to be released.
