Abstract

PROBLEM TO BE SOLVED: To provide a highly aseismatic flat glass panel device having a plurality of glass sheets installed continuously on a straight line without a support in between, capable of preventing fall off of and damage to the glass sheets without leaving a large clearance along a wall surface or a corner part, even when an especially large interlayer displacement has taken place.SOLUTION: A highly aseismatic flat glass panel device includes a pair of adjacent glass sheets of which one is a fixed glass sheet 5 that restricts out-of-plane displacement and the other is a movable glass sheet 6 that allows out-of-plane and in-plane displacement. The fixed glass sheet and the movable glass sheet are installed continuously on a straight line by connecting slanted surfaces 9 formed on edge members 7 installed along an edge part of the fixed glass sheet and an edge part of the movable glass sheet. When force is exerted on the movable glass sheet to move closer to the fixed glass sheet due to an interlayer displacement at a time of an earthquake, the slanted surfaces of both edge members slide to cause out-of-plane displacement of the movable glass sheet while causing in-plane displacement of the fixed glass sheet, allowing the glass sheets to slide in opposite directions without directly contacting each other.SELECTED DRAWING: Figure 3

Description

  The present invention relates to a high earthquake resistant flat glass panel device, and more particularly to a high earthquake resistant flat glass panel device in which a plurality of glass plates are continuously arranged on the same straight line without a support.

  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. In general, a suspended ceiling structure holds a ceiling support rail suspended vertically and horizontally by suspension support members (suspending bolts) suspended from an 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. Previously, 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. The displacement angle is required to withstand 1/60 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, various flat glass panel devices are conventionally provided in which a plurality of glass plates are arranged on the same straight line without a support between a ceiling rail attached to the ceiling and a ground rail laid on the floor surface. (See Patent Document 1). When these flat glass panel devices are connected to each other on the same straight line, the end members that are concavo-convexly fitted to each other are bonded to the end portions of the glass plates, and the end members are connected at the connecting portions of the adjacent glass plates. The projections and recesses are fitted to each other to regulate the out-of-plane displacement.

  However, when the wall or corner strut is rocked greatly due to the interlayer displacement during an earthquake, a large in-plane force acts on the glass plate adjacent to it, and the glass plate collides strongly at the connecting portion of the glass plate. It may be damaged.

On the other hand, in a normal state, the movable glass plate 6 is placed on the height retaining member 15 embedded in the recessed groove 13 at the lower end, and the upper end portion is shallowly engaged with the opening groove 11 of the top rail 3. Match. And the thing which wrapped the cushion material 16 with the rubber material 17 of the U-shaped cross section as the said elastic urging means 8 in the out-of-plane position of the said upper-lower-end part of the said movable glass plate 6 and the retraction | saving groove | channel 12 of the said top rail 3 It arrange | positions in the retraction groove | channel 14 of the said ground rail 4. FIG. The elastic biasing means 8 is provided in such a direction that the lip portion of the rubber material 17 contacts the surface of the movable glass plate 6. Here, the upper surface of the retaining member 15 is set substantially flush with the upper surface of the lower lip portion of the rubber member 17 of the elastic biasing means 8 provided in the retraction groove 14 of the ground rail 4, and the movable member 15 is movable. The upper end of the glass plate 6 is at a position lower than the top surface of the retreat groove 12 of the top rail 3. That is, the movable glass plate 6 is held by the top rail 3 and the ground rail 4 in a state in which out-of-plane displacement and in-plane displacement are allowed.

  And when the force of the direction which approaches the fixed glass plate 5 is added to the said movable glass plate 6 by the interlayer displacement at the time of an earthquake, the inclined surfaces 9 and 9 of the both end members 7 and 7 slide, and the said movable The glass plate 6 is displaced out of the plane from the upper surface of the height retaining member 15 to the retracting grooves 12 and 14 against the elastic biasing force of the elastic biasing means 8 and is displaced in the plane with respect to the fixed glass plate 5. It is evacuated to the draw state.

  The rubber material 17 is provided continuously from the fixed glass plate 5 to the movable glass plate 6, and the cushion material 16 is partially provided only at the position of the movable glass plate 6 to constitute the elastic biasing means 8. You may do it.
