Description

  The present invention relates to a highly earthquake-resistant glass panel device, and more particularly to a highly earthquake-resistant glass panel device in which there is no fear of dropping or breaking of a glass plate even with a large interlayer displacement.

  Normally, an office building or the like is formed of a plurality of slabs and each floor is formed, a suspended ceiling structure is constructed on the lower surface side of the upper slab, and a floor structure is constructed on the upper surface side of the lower slab and surrounded by a structural wall. The space is appropriately partitioned by a partition device. Usually, a suspended ceiling structure holds a ceiling support rail suspended vertically and horizontally by suspension support members (suspending bolts) suspended from the upper slab, and locks the periphery of the ceiling panel to the ceiling support rail It is a structure to do. A partition device combining partition panels and door panels is installed in the room having such a suspended ceiling structure from the ceiling panel to the floor structure. Here, a glass panel is often used as the partition panel in order to increase the openness of the space. Conventionally, there was no earthquake resistance standard for suspended ceiling structures, but due to the fact that many suspended ceiling structures were dropped and damaged by the Great East Japan Earthquake, the momentum to improve the earthquake resistance of the ceiling increased, and the interlayer deformation angle was 1 / It is considered necessary to withstand 60 to 1/40, seismic intensity 7, and ceiling surface acceleration 2.2G. Correspondingly, glass panels are required to have the same high earthquake resistance.

  On the other hand, a structure in which a plurality of columns are erected at intervals between a ceiling rail conventionally attached to the ceiling and a ground rail laid on the floor, and a glass plate is held between adjacent columns via a frame Various glass panel devices are provided. Here, although the said glass plate has the thing of the type divided | segmented into the one piece from a floor surface to a ceiling, and the upper and lower sides, in this invention, the glass panel which has a single piece glass plate is made into object.

  As a structure to hold the glass plate, a frame body that is connected to each other to enhance the strength is tightly fitted around the glass plate, or the frame body and the glass plate are adhered and fixed with a double-sided adhesive tape, and the rigidity is high. A structure in which a glass panel and the frame of the glass panel are locked to both side posts by a locking tool (see Patent Document 1), or a structure in which the frame of the glass panel is screwed to the side columns, the top rail, and the ground rail. (See Patent Document 2). Furthermore, vertical frames and horizontal frames are attached to both side supports, top rails and ground rails, and concave grooves provided on the vertical frames and horizontal frames, or concave grooves provided directly on both side posts, top rails and ground rails are used. The structure of holding | maintaining the circumference | surroundings of a glass plate through packing is common (refer patent document 3).

  However, when the struts are largely locked due to the interlayer displacement during the earthquake, the glass panel frame is abutted against the struts with a structure that locks the frame of the glass panel to the struts. Then, the glass panel will come off from the locking tool, and the structure that fixes the frame of the glass panel to both columns will also incline with the column, so the gap between the glass plate and the frame It is also assumed that a large stress acts and the glass plate is detached from the frame or the glass plate is damaged. On the other hand, a structure in which the periphery of the glass plate is held via packings in the recessed grooves of the vertical and horizontal frames attached to both side supports, the top rail and the ground rail, or the recessed grooves provided on both side supports, the top rail and the ground rail. In this case, it is assumed that when the struts are largely locked in accordance with the interlayer displacement during the earthquake, the packing is removed and the glass plate is dropped, or the glass plate collides with the vertical frame or the strut and is damaged.

  In addition, although patent document 4 is not related with a glass panel apparatus, frame material is arrange | positioned to the inner surface of frames, such as a pillar, a beam, and a foundation which comprise a building, and the substantially rectangular shape is formed on the inner surface of these frame materials. A wall surface structure of a building in which the elastic member is closely attached, and a flat plate-like face material that is slightly larger than the outer dimension of the elastic member and smaller than the inner dimension of the frame, A wall surface structure of a building having a damping function in which a face material is brought into close contact with the outside of the elastic member so as not to contact the inner surface of the frame is disclosed. When an earthquake occurs and horizontal movement force is generated in the frame, the face material moves in the horizontal direction relative to the surrounding four frame members, and the face material comes into contact with the inner surface of the column member in the moved direction. The material is pressed by the base and the beam, and the face material suppresses the deformation of the wall by the overall rigidity of the surface. The compressive force at this time can be dispersed and released to surrounding frames such as columns, foundations, and beams via elastic members, face materials, and frame materials.

  Here, it is preferable that the displacement amount of the glass plate in the holding groove of the frame body is 50 mm or more and 105 mm or less.

  Further, it is more preferable that a slider is attached to both side edges and upper edge of the glass plate from the end surface to the front and back surfaces of the glass plate, and the slider slides in the holding groove of the frame body. (Claim 3).

  And it is preferable to form the regulation step part which prevents the detachment | leave from the inside of this holding groove by stopping the said slider in the opening edge part of the said holding groove (Claim 4).

  Specifically, each of the frames includes a vertical frame member, an upper horizontal frame member, and a lower horizontal frame member, and includes a front side frame body and a back side frame body connected by the connecting metal fitting, and the front side frame body Comprises a holding plate that forms one side wall surface of the holding groove and a substrate that partially forms the bottom surface of the holding groove, and the back frame body has the holding plate and the substrate that form the other side wall surface of the holding groove.

Therefore, even if the support column is inclined and locked, the frame of the glass panel only deforms with the inclination of the support column, and the peripheral edge of the glass plate is allowed to be displaced in the holding groove of the frame. Since the glass plate does not collide with the frame body and is not damaged, and the glass plate is not dropped off, the glass plate can be stably held.

With a predetermined interval between the ceiling rail 3 and the ground rail 4. The glass panel 6 is attached using the side columns 5 and 5, the top rail 3, and the ground rail 4 that are erected. The glass panel 6 is composed of a glass plate 7 and a frame body 8. The frame body 8 connects the vertical frames 9, 9 on both sides, the upper horizontal frame 10 and the lower horizontal frame 11 with connecting metal fittings 12, and A holding groove 13 for holding the periphery of the glass plate 7 is provided in the inner peripheral portion, the frame body 8 is fixed to the column 5 on at least one side, and the frame 8 is inclined to the column 5 around the connection fitting 12. The holding groove 13 is sufficiently deep so that the periphery of the glass plate 7 does not come into contact with the bottom of the holding groove 13 when the frame body 8 is deformed. is there.

  As a result, as shown in FIGS. 2 and 3, the glass plate 7 can be stably held even when the support column 5 is tilted to be in a rocking state following the interlayer displacement during an earthquake. Each of FIG. 2 and FIG. 3A shows a normal state of the highly earthquake-resistant glass panel device, and the glass plate 7 is located at the approximate center of the frame 8. Each of FIGS. 2 and 3 (b) shows a state in which the frame body 8 is deformed with the inclination of the support column 5, and the peripheral edge of the glass plate 7 is relatively displaced in the holding groove 13, but the original is shown in FIG. Maintain the attitude.

  In general, an office building is divided into floors with slabs supported by structural columns and structural walls, a suspended ceiling structure is constructed on the lower surface side of the slab, and a floor structure body having wiring space on the upper surface side of the slab. Is building. In the present embodiment, the ceiling 1 corresponds to a suspended ceiling structure, and the floor 2 corresponds to a floor structure. And between the ceiling rail 3 attached to the lower surface of the suspended ceiling structure (ceiling 1) and the ground rail 4 attached to the upper surface of the floor structure (floor surface 2), the upper end is the ceiling rail 3, The lower end portion is provided with a plurality of support columns 5 at a predetermined interval so as to be able to follow the displacement of the ground rail 4.

  As shown in FIGS. 2 and 3, when an interlayer displacement occurs between the upper slab and the lower slab of a building due to an earthquake, the columns 5,. When the interlayer deformation angle is set to 1/40 at the maximum, when the floor height is 4200 mm, the interlayer displacement is 105 mm, and the displacement of the earthquake-resistant suspended ceiling structure that moves following the slab is also 105 mm. That is, this means that a standard ceiling height of 2800 mm is displaced by 105 mm on one side with respect to the floor surface. 2B and 3B, the horizontal displacement of the upper end with respect to the lower end of the column 5 is represented by ΔD.

  As shown in FIG. 7, the support column 5 is a square housing having a substantially C-shaped cross section that is open on one side surface. As shown in FIG. 1, the adjuster 14 is attached to the lower end and the concave groove of the ground rail 4 is installed.

As shown in FIG. 2, the sub-adjuster 16 is used to support the concave groove of the ground rail 4.

  Here, it is preferable that the displacement amount of the glass plate 7 in the holding groove 13 of the frame 8 is 50 mm or more and 105 mm or less. Although depending on the level of earthquake resistance, the horizontal displacement ΔD is 105 mm at the maximum as described above, and therefore the allowable displacement of the glass plate 7 in the holding groove 13 is also required to be 105 mm at the maximum. However, if this allowable displacement amount is set to be large, the horizontal width of the vertical frame 9 is increased by that amount, which causes a design problem.

In the connection fitting 12 of this embodiment, the connection plate 29 is on the same plane. The connecting metal fitting 12 may be a flat plate. In short, the connecting bracket 12 is required to deform the connecting portion between the vertical frame member 9 </ b> B and the upper horizontal frame member 10 </ b> B or the lower horizontal frame member 11 </ b> B so that the connection angle changes according to the locking of the support column 5. Is done.

  Each of the vertical frame members 9A and 9B, the upper horizontal frame members 10A and 10B, and the lower horizontal frame members 11A and 11B is cut at an end of 45 degrees, and the cut edges are joined to form an angle of 90 degrees. However, the cutting angle is not limited to 45 degrees.

  The front frame 8A is mounted from the front side between the support columns 5 and 5, and the glass plate 7 is placed on the elastic member 19 laid along the substrate 21 of the lower horizontal frame member 11A. Then, the back frame 8B is mounted between the columns 5 and 5 from the back to superimpose the substrate 21 and the bottom plate 25, and the holding plate 20 of the front frame 8A and the holding plate 24 of the back frame 8B. The frame 8 is configured by connecting the mounting plate 26 and the substrate 21 with screws 34 in a state where the peripheral edge of the glass plate 7 is sandwiched between the mounting plate 26 and the substrate 21. At this time, the vertical frame 9 on the side where the side plate of the column 5 exists is connected to the mounting plate 26 and the substrate 21 with the screw 34 and simultaneously screwed to the column 5, and the column 5 and the vertical frame are connected. 9 is integrated.
