Description

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 plate glass in an outer wall portion of a building or the like, and more specifically, a state in which end edges of panels are abutted without using a panel frame. However, the present invention relates to a panel support structure in a frameless method in which wall surfaces are arranged adjacent to each other and substantially form a wall surface only by the panel.

[0002]

2. Description of the Related Art In recent years, curtain wall construction methods have been diversified, and a construction method in which a transparent plate glass is used on the entire outer wall is also adopted in consideration of aesthetics and lighting. In the past, when plate glass was used for the panel surface, the main method was to support it with a metal frame material in consideration of wind resistance, earthquake resistance, etc. With the development of glass, it has become possible to meet the high demands for aesthetics, and without the use of a frame frame, the tempered glass is arranged vertically and horizontally adjacent to each other, and this tempered glass is directly supported by a supporting metal object. The construction method has been developed and many construction results are left.

In this frameless construction method, for example, as described in Japanese Patent Laid-Open No. 5-248018, mounting holes are formed in the four corners of the tempered glass, and a supporting portion is provided in the mounting holes. By attaching a special hinge type support bolt that suppresses the stress generated by making it freely rotatable, the support member and the tempered glass are connected, and another structure or body is fixed to the support member through this support member. In the case of the publication, as the supporting device for supporting the four sheets of glass, as shown in FIG. 12, an H-shaped (or X-shaped) panel supporting member 30 and the panel supporting member 30 are connected. The supporting member 29 is provided, and a supporting bolt 31 is provided at the tip 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 panel deformation and interlayer displacement caused by wind pressure or seismic force, for example, a structure described in JP-A-5-239876 can be mentioned. In the case of the publication, as shown in FIG.
Each of the support arm members 33, 33 ... Of the panel support member 32 has a bolt through hole 34, 34 ... Formed in the panel support portion at the front end as a horizontally elongated circular hole, and a linear line is formed on one nut seat surface of these panel support portions. By forming a groove 35 and forming a similar linear groove that engages with the linear groove 35 on the washer surface that abuts against the surface on which the linear groove 35 is formed, the panel holding portion has a position fixing structure. As for the remaining three supporting portions, as shown in FIG. 14, the bolt screw portion 36a of the glass mounting member 36 is allowed to freely move within the dimension of the oblong circular hole, and the movement and temperature of the panel due to wind pressure or seismic force and temperature. The panel is designed to handle expansion and contraction due to changes in humidity.

[0005]

However, in the panel support structure, when the fastening force of the nut member is too strong, the panel may move due to friction between the nut seat surface and the panel support portion surface. There is a problem that adjustment of the nut fastening force is very difficult because the situation in which the nut cannot be performed occurs and when the fastening force of the nut member is too weak, the nut member loosens or falls off.

Further, the deformation absorbing structure of the panel is intended only for absorbing the deformation in the lateral direction of the panel, and no consideration is given to the movement of the panel in the vertical direction and the expansion and contraction. Therefore, it is effective for rolling seismic waves with a relatively long period, but vertical panel deformation can be tolerated for direct type seismic waves and seismic waves with short period pitching. It has almost no effect. Further, the deformation due to wind pressure and the expansion and contraction due to thermal expansion will cause the same amount of deformation in the horizontal and vertical directions if the panel shape is a square. In any case, in order to absorb the planar deformation due to thermal expansion or the like, it is necessary to be able to simultaneously absorb not only the lateral deformation but also the vertical deformation.

On the other hand, the panel behavior when a relatively large seismic wave is received is that the entire panel is deformed so as to rotate rather than move in one direction in the horizontal or vertical direction. It is important to have a structure that can effectively absorb such rotational deformation.

Therefore, a main object of the present invention relates to a panel support structure for directly supporting a panel without having a frame frame, and it is possible to easily achieve a nut tightened state satisfying both fastness and slidability. Another object of the present invention is to provide a panel support structure capable of absorbing not only lateral movement / deformation of the panel but also vertical deformation / movement and rotational deformation of the panel.

[0009]

In order to solve the above problems, the present invention relates to a panel for fastening a panel support bolt, which is attached to a panel support member toward the room side and orthogonally, to a panel support member with a nut. In the support structure, the panel support member has a through hole into which a panel support bolt is loosely fitted in a panel support part, and an intermediate fastening member / intermediate attachment tool between the panel and the panel support part. It is configured to be fixed by a nut member that is fastened to the panel support bolt in a state in which members are interposed, and a key member is fitted in a groove formed in a screw portion of the panel support bolt and extending along a longitudinal direction of the member. Further, the distance between the nut member and the intermediate fastening member / intermediate fittings is restricted by the protruding step formed on the key member.

In this case, by interposing a slippery sliding disc liner between the intermediate fastening member / intermediate fixtures and the panel support portion and between the nut member and the panel support portion, Can be easily moved. In the present invention, the term "intermediate fastening member / intermediate fittings" refers to a state in which the panel is sandwiched by being screwed to the panel support bolt 3 such as the fastening intermediate nut 5 in the section of the embodiment described later. It refers to a fastening member that supports, or an intervening member that is inserted into the panel support bolt 3 in order to secure a distance between the panel and the panel-side member piece N.

Therefore, according to the present invention, the key member fitted in the groove of the panel support member, specifically the nut member and the intermediate fastening member / intermediate with respect to the protruding step portion formed on the key member. When a part of the fixtures abut, the distance between the two is regulated and the frictional force with the panel support member surface is adjusted to an appropriate value, so that the nut member is in a state where both the fastening property and the slidability are satisfied. It is concluded.

Further, since the tip end portion of the key member is inserted into the intermediate fastening member / intermediate attachment region, the intermediate fastening member / intermediate attachment is prevented from rotating.

According to the present invention, at least one boundary surface of the fastening nut member and the intermediate fittings attached to the panel support bolt is an arc-shaped curved surface on another side of the panel support structure, for example, on each side straddling the panel support portion. With this, the present invention can be applied to a support structure in which the panel support bolt can swing freely. Here, the "fastening nut member and intermediate fittings" include not only end fastening nuts used for bolt fastening and the intermediate fastening members, but also intervening members and washer members that are inserted into the support bolts. Refers to all bolt insertion members.

On the other hand, according to the present invention, the panel support member commonly supports at least two vertically adjacent panels, and the panel support bolt on one side of the adjacent upper and lower panels is provided in the through hole. It is supported by a bolt receiving member placed inside.

Therefore, in the panel supporting structure according to the present invention, the panel is supported not only in the horizontal direction but also in the vertical direction (strictly, only one side in the vertical direction) while being supported in the suspended state or the under-supported state. It will be possible to absorb the rotation of the panel at the same time.
