Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earthquake-resistant structure for a glass screen formed by a rib glass method.

[0002]

2. Description of the Related Art Among glass screen methods for forming a large opening using a large plate glass as an outer wall of a building, a glass stabilizer method and a hanging stabilizer method are well known as methods using rib glass (glass cubic). I have.

The glass stabilizer method is also called a self-supporting method with a glass cubic, and uses rib glass (also referred to as a cubic glass or a glass stabilizer) to support the deflection caused by the weight of the face glass and the wind load applied to the face glass. The hanging stabilizer method is a method of suspending the upper side of the glass plate and using a rib glass to prevent bending of the glass plate due to its own weight, and is used when the height of the glass plate at the opening is high. It is.

[0004] As a configuration of the rib glass of the above-mentioned method, the vertical sides of a plurality of face plate glasses to be erected are abutted, and the rib glass is erected on the indoor side or the outdoor side at right angles to the abutting portion, and the abutting between the glass plates is performed. A single rib method in which joints are filled with a structural sealing material, or rib glass is erected on both the indoor side and the outdoor side at right angles to abutting portions of the vertical sides of a plurality of face glass sheets to be erected, and each glass is erected. A double rib method in which the joints between the plates are filled with a structural sealing material, and a plurality of face plates are made to penetrate through the joints where the longitudinal sides of the glass plates meet. Three types of through-rib construction methods in which a piece of rib glass is erected on both sides of the glass and the joint of the gap between the face glass and the rib glass is filled with a structural sealing material. Has been used in the past, and the abutting portion between the face glass and rib glass is sealed with a high modulus elastic sealing material. Lumber was used.

[0005]

In any of the methods using rib glass, when interlayer displacement occurs due to an earthquake or the like, the upper frame is connected to the structure and moves, so that the upper frame is shown in FIGS. While the rib glass is forced to tilt, the face glass uses a low modulus sealing material as a sealing material with the upper frame, so the deformation of the sealing material makes the face glass unable to lock. There is a case where the rib glass is damaged by the S-shaped deformation of the rib glass in an out-of-plane direction.
In order to lock the face glass so as not to damage the rib glass, the reaction force generated in the sealing material between the upper frame and the face glass must overcome the repulsive force of the sealing material between the rib glass and the face glass.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a rib glass reliably receives positive and negative wind loads on a face glass.
One side of abutting portions of a plurality of face-plate glass standing upright as an outer wall for the purpose of locking the face-plate glass when subjected to interlayer displacement due to an earthquake or the like and preventing the rib glass from deforming in an out-of-plane S-shape to prevent breakage. Alternatively, in the glass screen method in which rib glass is provided on both sides at right angles to the vertical side of the face glass, and the face glass and the rib glass are supported by the upper frame and the lower frame, the elastic modulus of the sealing material between the upper frame and the lower frame, the face glass, and the rib glass. Is larger than that of the sealing material at the abutting portion of the rib glass and the face glass, or a rib glass is provided on one or both sides of the abutting portion of the plurality of face glass to be erected as an outer wall, at right angles to the vertical side of the face glass. , A glass screen method in which face glass and rib glass are supported by upper and lower frames As a sealing material between the face glass and the rib glass, the elastic coefficient of the elastic sealing material near the upper part and the lower part of the longitudinal side of the rib glass is set to be relatively smaller than that near the central part, or as an outer wall. A rib glass is provided on one side or both sides of a butt portion of a plurality of face glass sheets to be provided at right angles to a vertical side of the face glass sheet,
In the glass screen method in which the face plate glass and the rib glass are supported by the upper frame and the lower frame, a projecting member is fixed to the lower end of the upper frame supporting the upper side of the face plate glass and the upper end of the butted portion between the face plate glasses, and further fixed to the upper frame. The projection member is made of weather-resistant hard rubber such as chloroprene rubber or the like and has a hardness of about 80 to 90 degrees, or a rubber sheet is adhered to the surface of a metal member such as an aluminum material as the projection member fixed to the upper frame.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is directed to a butt portion of a face glass and a face glass in which an upper side of a large-area face glass is suspended or fitted into an upper frame, the lower side is supported by a lower frame, and a rib glass is erected. And, the rib glass is erected on one side or both sides at right angles to the face glass, and a structural sealing material is filled between the vertical side of the face glass and the rib glass vertical side, and the upper frame and the lower frame, the face glass and The sealing material filled between the rib glasses was filled with a sealing material having a larger elastic coefficient than the sealing material at the abutting portion between the rib glass and the face glass, and was bonded.

That is, the face glass and the upper frame or the lower frame are filled with a high modulus elastic sealing material, and the abutting portion between the rib glass and the face glass is filled with a medium modulus sealing material. The upper frame moves in the direction parallel to the face of the face glass,
The rib glass is forcibly inclined to the right and left in an S-shape by the upper frame of the rib glass, but the sealing material between the face glass and the upper frame is made of a harder material than the rib glass seal, so the displacement of the upper frame is accompanied by the displacement movement of the upper frame. The upper side of the face glass also moves, and the face glass is locked, and the rib glass does not deform in an S shape, so that the rib glass does not break.

Next, as a sealing material between the face glass and the rib glass, a middle modulus elastic sealing material is provided near the upper and lower portions of the longitudinal side of the rib glass, a high modulus elastic sealing material is provided near the central portion thereof, or a vertical portion of the rib glass is provided. The elastic modulus of the elastic sealing material near the upper and lower parts of the vertical side, such as the lower modulus elastic sealing material near the upper and lower parts of the side and the middle modulus elastic sealing material near the central part, It was made relatively smaller than that.

This is because, when the upper frame is moved in a direction parallel to the surface of the face glass by interlayer displacement due to an earthquake or the like, the rib glass is forcibly moved out of the plane by the upper frame of the rib glass.
However, the upper and lower parts of the butted part of the rib glass and the face glass were made softer than the center part, so the rib glass was forcibly moved as the upper frame of the rib glass moved. If the S-shaped deformation of the rib glass caused by insufficient inclination of the face glass and the locking of the face glass is made lower in the vicinity of the upper and lower parts of the rib glass seal than in the vicinity of the central part, the sealing material is elongated. The rib glass is not severely deformed, and the rib glass is not damaged.

Alternatively, a projection member for forcibly locking the face plate glass is fixedly connected to the upper frame at the lower end of the upper frame supporting the upper side of the face plate glass and at the upper end of the abutment between the face plate glasses. Regardless of the state, when the upper frame moves in the direction parallel to the surface of the face glass due to interlayer displacement due to an earthquake or the like, the projecting member connected and fixed to the upper frame forcibly transmits external force to the upper side of the face glass, Locking of the glass is likely to occur, and the deviation of the movement from the rib glass that is forcibly tilted by the upper frame of the rib glass is reduced, so that it is easy to follow the interlayer displacement.

Further, if the rib glass is a laminated glass, the strength of the rib glass is increased, and if the thickness of the rib glass is further increased, the margin of the rib glass with the vertical edge of the face plate glass is increased. In addition, the rib glass can reliably receive both positive and negative wind loads.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The seismic isolation structure of a rib glass screen according to the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a cross-sectional view of a ribbed glass screen according to an embodiment of the present invention, in which a part of a seismic isolation structure is omitted. FIG. FIG. 2B is a schematic front view illustrating the balance and locking of the face glass. FIG. 2B is a schematic front view illustrating a state in which the locking of the face glass is small and the rib glass is deformed into an S shape when interlayer displacement occurs. 3 and 4 show perspective views of a ribbed glass screen for explaining another embodiment of the present invention, in which a part of a seismic isolation structure of a rib glass screen is partially omitted, and FIG. 5 shows interlayer displacement according to still another embodiment of the present invention. FIG. 6 is a schematic front view in which a part of the seismic isolation structure of a rib glass screen in which a part of a seismic isolation structure of a rib glass screen is cut away is omitted. Shown, FIG. 7 (a), (b)
2A and 2B are schematic front views of the glass plate before and after the occurrence of interlayer displacement, which are partially cut away and omitted, respectively, by the conventional rib method.

As shown in FIG. 1, a plurality of face glass sheets 1 serving as openings of a building are erected in parallel, and a rib glass 2 is placed on one side or in a direction perpendicular to the face glass sheet 1 at abutting portions of the face glass sheets 1. It was set up on both sides (not shown). The face glass 1 and the rib glass 2 are supported and fixed in a lower frame 4 and an upper frame 3 connected to a structural body (not shown), respectively.

As an embodiment of the present invention, as shown in FIG. 1, the upper frame 3 or the lower frame 4 and the upper frame seal 6 and the lower frame seal 8 in the face plate glass 1 are made of a low modulus silicone sealing material of a conventional method. In place of the elastic sealing material, a silicone-based sealing material having a high modulus of elasticity is used. Further, a high modulus silicone is used as a rib glass seal 7 at the butting portion between the vertical sides of the face glass 1 and at the butting portion between the rib glass 2 and the face glass 1. Instead of the system sealing material, a medium modulus silicone sealing material having an elastic coefficient smaller than that of the upper frame seal 6 and the lower frame seal 8 was used.

Since the rib glass seal 7 has a smaller elastic coefficient than the upper frame seal 6 and the lower frame seal 8, the rib glass seal 7 is applied to the surface of the face glass 1 by interlayer displacement 9 due to an earthquake or the like as shown in FIGS. When the upper frame 3 moves in the parallel direction, the rib glass 2 is forced to tilt by the upper frame 3 and the lower frame of the rib glass 2 moving in opposite directions. Since the upper frame seal is made of a material harder than the rib glass seal 7, the upper side or the lower side of the face glass is moved by being dragged by the movement of the upper frame or the lower frame, that is, the upper frame 3 and the upper frame seal of the face glass 1 are moved. 6. The reaction force generated in 6 overcomes the repulsion of the rib glass seal 7 of the glass rib 2, so that the locking 10 of about 1/100 to 1/150 is easy. Corruption will Ribugarasu 3 can be prevented.

Next, another embodiment of the present invention will be described. As shown in FIGS. 3 and 4, as the structural sealing material, for example, about １ ／ of the upper part of the vertical side of the rib glass 2 is used.
About 1/5 and about 1/8 to about 1/5 of the lower part were made into a low modulus or middle modulus elastic sealing material, and the remaining central part was made into a middle modulus or high modulus elastic sealing material. That is, the upper and lower elastic sealing materials are soft sealing materials having a relatively smaller elastic coefficient than the central elastic sealing material.

This is because when the upper frame moves parallel to the surface of the face glass 1 due to interlayer displacement due to an earthquake or the like, the rib glass 2
When the rocking of the face glass is insufficient, the structural sealing material of the abutting portion between the rib glass 2 and the face glass 1 is generated by the upper frame 3 of the rib glass 2. As shown in FIG. 2B, the upper and lower portions of the rib glass 2 are displaced in an S-shape as shown in FIG.

On the other hand, since the rib glass seal 7 needs to withstand positive and negative wind pressure loads, it is desirable that the rib glass seal be higher. Therefore, when the upper and lower portions of the rib glass seal 7 have low modulus, the rib glass seal 7 'in the center portion. Is a middle modulus sealing material, and when the upper and lower portions have a middle modulus, the central portion of the rib glass seal 7 'is a high modulus sealing material.

The locking of the face glass 1 is insufficient with respect to the rib glass 2 forcibly deformed by interlayer displacement as described above, and even if the vicinity of the upper portion and the lower portion of the butted portion of the rib glass 2 and the face glass 1 are largely shifted, By making the upper and lower portions of the rib glass seal 7 lower and softer than the central portion, the sealing material 7 is stretched and deformed, and the rib glass 1 is prevented from being excessively deformed into an S-shape, thereby preventing the rib glass 2 from being damaged. be able to.

Next, as still another embodiment of the present invention,
As shown in FIGS. 5 and 6, hard chloroprene having a hardness of about 80 to 90 degrees is provided at the lower end of the upper frame 3 that supports the upper side of the face glass 1 and at the upper end where the plurality of face glass 1, 1,. The protrusion member 5 made of rubber was fixedly connected to the upper frame. The protruding member 5 has such a size as to fit within the joint of the abutting portion between the face glass sheets 1, 1,..., And is covered with a rib glass seal 7 filled between the rib glass 2 and the face glass sheets 1, 1,. Regardless of the state of the sealing material such as the upper frame seal 6, the lower frame seal 8, the rib glass seal 7, etc., the upper frame 3 is moved in a direction parallel to the surface of the face glass 1 by interlayer displacement 9 due to an earthquake or the like as shown in FIG.
When the is moved, the projecting member 5 connected and fixed to the upper frame 3 forcibly transmits an external force due to interlayer displacement to the upper side of the face glass 1 to easily generate the locking 10 of the face glass 1 with the inclination of the rib glass, It is intended to reduce the deviation of the movement from the rib glass 2 and make it easier to follow the interlayer displacement 9, thereby eliminating breakage of the rib glass.

If the rib glass 2 is made of laminated glass, the strength of the rib glass 2 is increased and the thickness of the rib glass 2 is increased, so that the margin between the rib glass 2 and the vertical edge of the face plate glass 1 is increased, and the filled rib glass seal 7 is formed. With rib glass 2
Thus, both positive and negative wind loads can be reliably received.

The present invention can be applied to any one of the single rib, the double rib, the through rib, and the like, and is not limited to the above embodiment.

The rib glass seal 7 to be filled between the rib glass 2 and the face glass 1 is not limited to a silicone-based seal material, and a low modulus sealing material such as a polysulfide-based seal material can be used. The upper frame seal 6 filled between the upper frame 3 and the lower frame 4 and the lower frame seal 8 filled in the lower frame 4
