DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel support structure for directly supporting a panel such as a sheet glass on an outer wall portion of a building or the like, and more particularly, to a state in which edges of panels are abutted without using a panel frame. The present invention relates to a panel support structure in a frameless method in which a wall is formed substantially only by a panel while being adjacently arranged.

[0002]

2. Description of the Related Art In recent years, curtain wall construction methods and the like have been diversified, and a construction method using a transmission plate glass on the entire outer wall has been adopted in consideration of aesthetics and lighting. Conventionally, when using sheet glass for the panel surface, the method of supporting the surrounding area with a metal frame material in consideration of wind resistance, earthquake resistance, etc. has been mainly used, but in recent years it has been strengthened with excellent strength. With the development of glass, it has become possible to respond to high demands for aesthetics, and a frameless system in which tempered glass is arranged vertically and horizontally without using a frame, and this tempered glass is directly supported by supporting hardware. The construction method has been developed and many construction results have been left.

In this frameless construction method, for example, as described in Japanese Patent Application Laid-Open No. Hei 5-248018, mounting holes are formed at four corners of the tempered glass, and a supporting portion is formed with respect to the mounting holes. A special hinge-type support bolt that suppresses the generated stress by being freely rotatable is attached to connect the support member and the tempered glass, and fixed to another structure or skeleton through this support member In the case of the publication, as shown in FIG. 19, an H-shaped (or X-shaped) panel supporting member 30 and a supporting device connected to the panel supporting member 30 are used. The supporting rod member 29 is provided with a supporting bolt 31 at the distal end of each supporting arm member of the panel supporting member 30.

On the other hand, in such a frameless construction method,
It is desired that the panel has a structure that allows a certain degree of deformation of the panel so that excessive local stress is not generated in the panel during a storm or an earthquake. As a structure for absorbing deformation and interlayer displacement of a panel caused by wind pressure or seismic force, for example, a structure described in JP-A-5-239876 can be mentioned. In the case of this publication, as shown in FIG.
The bolt through holes 34, 34 ... formed in the panel support portions at the distal ends of the support members 33, 33 ... of the panel support member 32 are formed as oblong holes, and one of these panel support portions is formed with a linear nut seating surface. By forming a groove 35 and forming a similar linear groove that engages with the linear groove 35 on a washer surface that comes into contact with the surface on which the linear groove 35 is formed, the panel holding portion has a position fixing structure. As for the remaining three support portions, as shown in FIG. 18, the bolt screw portion 36a of the glass mounting member 36 can be freely moved within the oblong hole size, and the movement of the panel due to wind pressure or seismic force and temperature. In addition, it is possible to cope with expansion and contraction of the panel due to a change in humidity.

When adjusting the position of the panel support device in the indoor and outdoor directions, the entire panel support member 30 is rotated around the axis of the support member 29, so that the base metal on the structural support side and the support member 29 are connected to each other. This is performed by adjusting the screwing amount.

[0006]

However, the deformation absorbing structure of the panel supporting device is intended only for absorbing the deformation of the panel in the horizontal direction, and is not applicable to the vertical movement or expansion and contraction of the panel. No consideration has been given. Therefore, it is effective for relatively long-period rolling seismic waves, but it can tolerate vertical panel deformation for direct-type earthquake waves or short-period seismic waves. Almost no effect. In addition, deformation due to wind pressure or expansion and contraction due to thermal expansion results in the same amount of deformation in the horizontal and vertical directions if the panel shape is square. In any case, in order to absorb planar deformation due to thermal expansion or the like, it is necessary to be able to simultaneously absorb not only horizontal deformation but also vertical deformation. In addition, the behavior of the panel when it receives a relatively large seismic wave is not limited to moving the entire panel in one direction in the horizontal or vertical direction, but often deforms to rotate. It is important to have a structure that can effectively absorb even a rotational deformation.

To solve this problem, Japanese Patent Laid-Open Publication No. 7-20778
No. 7 discloses that each of the four bolt through holes on the panel support member side has a larger diameter than the outer diameter of the mounting bolt on the panel side.
And a bolt supporting member capable of vertically supporting the mounting bolt is inserted into the upper two or lower two bolt through holes,
There has been proposed a panel support structure in which the mounting bolt is seated to support the panel.

However, in consideration of an actual panel mounting procedure, the panel must first be mounted in a state where the bolt supporting member is fitted in the bolt through hole of the panel supporting member. While the unit is being adjusted in the left-right or up-down direction, the panel mounting bolt is eccentrically loaded on the bolt support member or causes delicate contact, and the bolt support member falls out of the bolt through hole. There are concerns about such situations.

On the other hand, in the case of the panel supporting structure described in Japanese Patent Application Laid-Open No. 5-239876, the panel supporting member must be positioned so that all bolt through holes are horizontally long. Adjustment of the position of the panel support member 32 in the indoor and outdoor directions is inevitably performed at every 360 ° rotation of the panel support member 32, and the minimum adjustment unit is the screw pitch. For this reason, it is difficult to adjust the panel support member 32 with a small precision equal to or less than the screw pitch, which causes a problem that it is difficult to obtain a high surface alignment precision between adjacent panels.

To cope with this problem, Japanese Patent Application Laid-Open No. 7-207
No. 785 discloses a panel support member in which four bolt holes formed in each support arm are formed in a large-diameter square hole, and these large-diameter square holes are pointed about a center position of the panel support member. By arranging the panel support members on the object, it is possible to adjust the in / out of the panel support member at every 90 ° rotation to improve the adjustment accuracy.

Certainly, in the case of the panel support device described in Japanese Patent Application Laid-Open No. 7-207785, although the minimum adjustment unit is small and high-precision adjustment is possible, positioning is performed in exactly the same shape every 90 ° rotation. When the panel support member is rotated to adjust the position by a predetermined amount, the current rotation amount of the panel support member is unknown during the adjustment, and a situation such as re-measurement may occur. Sometimes you get.

Therefore, a main object of the present invention relates to a panel supporting structure for directly supporting a panel without a frame. First, not only a lateral movement / deformation of a panel but also a vertical direction. Secondly, when adjusting the panel support member in the indoor / outdoor direction, the shape of the bolt through hole formed in each panel support portion is adjusted under predetermined conditions. By changing it, it can be used as an index for confirming the amount of rotation adjustment of the panel support member, and at the same time, a bolt receiving member can be commonly used for each bolt through hole to avoid complexity. And to ensure that the bolt receiving member does not fall.

[0013]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a panel which is disposed adjacent to a panel with its edges abutting each other. A panel support structure adapted to be supported by a panel support member connecting the body and the panel support member, wherein the panel support member has a connection portion with the structure support side at a central portion thereof, and is provided between the panel support member and the structure support body. A panel support portion is provided in a symmetrical arrangement, which is attached via a threaded connection portion and commonly supports at least two adjacent panels with the center connection portion as a boundary. Bolt through holes are formed in the vicinity of the panel corners for loosely inserting panel support bolts attached at right angles to the panel surface toward the room side with a predetermined gap, and before the bolts are loosely inserted into the bolt through holes. With a structure fixed by a nut member fastened to the panel support bolt, the through hole shape of each of the bolt through holes is limited to a substantially rectangular shape of a predetermined size, and at a point symmetrical position with respect to the central connecting portion. One of the bolt holes is formed in a vertically long shape, and the other bolt hole is formed in a horizontally long shape. In this case, on one side of the upper and lower portions of the panel, a panel support bolt attached to the panel is supported by a bolt support unit including a bolt receiving member and an adjustment liner plate disposed in the bolt through hole. To do it.

Therefore, in the case of the present invention, as schematically shown in FIG. 14, since each bolt through-hole is formed asymmetrically with respect to the center point, the panel supporting member is rotated around the connecting portion axis. When the bolts are rotated in the vertical direction, the vertical or horizontal relative relationship of each bolt through-hole shape completely matches at the time of 360 ° rotation, and does not match during other rotation states. Therefore, it is possible to confirm the current rotation adjustment amount of the panel support member using the relative shape relationship as an index, and it is possible to prevent the already-adjusted adjustment amount from becoming unknown during the rotation. As shown in FIG. 15,
When the vertical or horizontal relationship of the bolt through-hole shape is set to be point-symmetrical, the relative relationship is the same for every 90 ° rotation. This can be easily understood by rotating the paper surface of FIGS. 14 and 15 every 90 degrees. In FIG. 14 and FIG. 15, a horizontal line indicates a horizontally elongated bolt through hole, and a vertical line indicates a vertically elongated bolt through hole.

In the above case, in order to enable the bolt receiving member to be commonly used for each of the vertically or horizontally arranged bolt through holes, the long side of each of the substantially rectangular bolt through holes is required. A groove having a groove depth of (long side length−short side length) / 2 is formed at each central portion of the two sides along the indoor / outdoor direction. That is, the grooves are formed such that the distance between the grooves is equal to the long side dimension. On the other hand, a protrusion having the same dimension as the groove is formed at a position corresponding to the lower surface side of the bolt receiving member.

Therefore, as shown in FIG. 16, when the bolt through hole has a horizontally long shape, the front bolt receiving seat member has a groove formed in each central portion of the two long sides. In the case where the protrusion of the bolt receiving member is fitted and disposed with respect to and the bolt through hole has a vertically long shape, the protrusion of the bolt receiving member is placed on the lower short side. In these cases, the receiving level of the bolt receiving member can be kept relatively constant in any of these cases. It can be commonly used regardless of.

On the other hand, according to a bolt support unit installed in the bolt through hole, the bolt receiving member is inserted into the bolt through hole, and an insertion engagement having a locking piece formed in the insertion portion. And a contact plate that comes into contact with the outer wall surface around the bolt through hole as one of a pair, and is inserted into the bolt through hole, and a receiving and locking piece is formed in the insertion portion. The other member of the pair is a member consisting of an insertion engagement portion and a contact plate that comes into contact with the outer wall surface around the bolt through-hole portion, and these members are respectively fitted from both openings of the bolt through-hole. The members are integrated with each other by engaging each other. Therefore, even if the panel mounting bolt is eccentrically loaded on the bolt support member or makes a slight contact while the panel unit is being adjusted in the left-right or up-down direction, the bolt receiving member can be used. It does not fall off from the through hole. In this case, preferably, in the pair of bolt receiving members, when the insertion engagement portions are engaged with each other to achieve integration, a gap hole is formed in the engagement portion. It is desirable to form an engaging piece and a receiving engaging piece and fit a key member into the gap hole to prevent disengagement of the pair of bolt receiving members.
As a result, a fall prevention measure is thorough.

As the key member, for example, a single member can be used, but a projection is formed on the lower surface side of the adjustment liner plate of the bolt support unit so as to be fitted into the gap hole of the bolt receiving member. It is desirable to prevent the bolt receiving member from being disengaged at the same time as mounting the adjustment liner plate.

On the other hand, in the nut fastening portion of the panel support bolt, the panel support bolt is fastened with an intermediate fastening member / intermediate fittings interposed between the panel and the panel support member. A spacing tube is provided between the fastening member / intermediate fittings and the nut member so as to be externally fitted to the panel support bolt, so as to regulate a separation distance between the intermediate fastening member / intermediate fittings and the nut member. It is desirable. In this case, the movement of the panel is facilitated by interposing a sliding disc liner between the intermediate fastening member / intermediate fixtures and the panel support and between the nut member and the panel support. be able to. In the present invention, the term “intermediate fastening member / intermediate fittings” refers to an intermediate nut 5 for fastening in a column of an embodiment to be described later, which is screwed to the panel support bolt 3 to sandwich the panel. It refers to a fastening member to be supported, or an interposed member or the like that is inserted into the panel support bolt 3 to secure a separation distance between the panel and the panel-side member piece N.

Therefore, the distance between the intermediate fastening member / intermediate fittings and the nut member is regulated by the spacing tube, and the frictional force with the panel supporting member surface is adjusted to an appropriate value, so that the fastening performance and the slideability are improved. The nut member is fastened so as to satisfy both the properties.

Is formed. In other words, the total size plus groove 2j, the depth of 2k to the short side dimension L _S of the long side dimension L _L and the same as made as the groove 2j, 2k are formed. On the other hand, as will be described later, protrusions 11e and 12e having the same dimensions as the groove grooves 2j and 2k are formed at positions corresponding to the lower surfaces of the bolt receiving members 11 and 12, respectively. Therefore, as will be described later, the receiving level of the bolt receiving members 11, 12 can be kept relatively constant irrespective of whether the shape of the bolt through holes 2e to 2h is vertical or horizontal. Therefore, the bolt receiving members 11 and 12 can be commonly used.

On the other hand, the supporting structure of the panel P firstly fits the rubber ring 1 into the countersink hole 27 formed in the corner of the panel P.
6 and the fixing bush 13 are interposed, the panel support bolt 3 is inserted from the outside of the room, and a thrust plate using a high-strength resin such as a polyamide resin for the panel support bolt 3 on the back side of the panel P. After loosely fitting the panel 4, the fastening intermediate nut 5 having the female screw hole 5b formed at the center and the locking nut 9 are screwed together and fixed while the panel P is sandwiched. The panel support bolt 3, the thrust plate 4, the fastening intermediate nut 5, and the locking nut 9 are preferably attached to the panel P before being carried into the site.

Next, the spacing tube 10 is inserted into the panel support bolt 3 and a sliding ring plate 6a made of stainless steel or the like arbitrarily selected as a material having a small friction coefficient.

As described above in detail, according to the present invention, the present invention relates to a panel supporting structure for directly supporting a panel without having a frame, not only moving and deforming the panel in the horizontal direction but also in the vertical direction. It can also absorb deformation and movement of the panel and rotational deformation of the panel.

In adjusting the direction of the panel supporting member in the indoor and outdoor directions, the shape of the bolt through hole formed in each panel supporting portion is changed under predetermined conditions. This eliminates the possibility of making an incorrect adjustment amount. In this case, by setting the shape of the bolt through hole and the shape of the bolt receiving member to a predetermined shape, it is possible to commonly use the bolt receiving member for each vertically or horizontally long bolt through hole. it can.

Further, since the bolt receiving member is formed as a set of two divided pieces, which are inserted from both openings of the bolt through holes and are engaged with each other, even when the panel unit is installed, the bolt receiving member is also provided. This has various advantages such as that the seat member never falls.
