Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate glass construction structure which is not easily damaged by an earthquake or the like.

[0002]

2. Description of the Related Art In buildings such as buildings, there is a construction method of forming a large glass screen using sheet glass. At this time, the sheet glass is hung at the upper part without relying on a method of supporting the sheet glass with a strong supporting frame such as an aluminum sash. There is a suspension construction method that supports its own weight, or an under construction method that receives the own weight of the face plate glass with a lower fixed frame.

In the case of forming such a large glass screen, there is provided a construction method capable of constructing an outer wall without impairing the continuity of the flat glass surface. By providing a flat glass forming a wall surface, that is, a rib flat glass behind a face flat glass, There is a large glass screen construction method that supports surface loads such as wind pressure on the face plate glass.

FIG. 14 shows a perspective view of a conventional example which is a large-sized glass screen construction method of a type in which a face plate glass is placed under such construction method. In FIG. 14, a face plate glass 1, which constitutes a wall surface with fixed upper and lower ends,
1 and the rib plate glass 2 orthogonal to it are joined by a seal material 4 at the butting portion. The lower ends of the face plate glass 1 and the rib plate glass 2 are fixed by a lower fixed frame 3b, and the upper ends thereof are also fixed by an upper fixed frame 3a (not shown). The upper fixed frame 3a and the lower fixed frame 3b are collectively referred to as a fixed frame.

FIG. 15 is a sectional view of an essential part of a portion B of the plate glass construction structure shown in FIG. 14, showing a sectional view of a lower end portion of a rib plate glass according to a conventional example. The lower fixed frame 3b is the frame 11
And is installed so as to be hidden by the floor material 10. Reference numeral 12 is a spacer. Lower fixed frame 3
A setting block 6 is fixed to the lower end of the rib plate glass 2 in b, and the fixed frame 3b receives the weight of the glass through the setting block 6. A backup material 1 is provided in the gap between the rib plate glass 2 and the lower fixed frame 3b.
7 and 17 are packed therein, and the outside thereof is sealed with a sealing material 16 such as silicone sealant.

The rib plate glass 2 that resists external force such as wind pressure is joined to the face surface of the face plate glass 1 without traveling, so that the face plate glass 1 can continuously form a flush vertical wall surface. There is.

Therefore, according to this conventional example, only the rib plate glass 2, the upper fixed frame 3a, and the lower fixed frame 3b are used, and in addition, a supporting frame member is used between the face plate glass 1 and the face plate glass 1. Without fail, the continuity of the glass surface can be secured.

However, in the construction structure of the sheet glass by such a conventional construction method, there is a problem that some glass sheets are damaged by a large earthquake.

In the conventional example shown in FIGS. 14 and 15, displacement of the face plate glass 1 and the rib plate glass 2 when interlayer displacement occurs in the body due to an earthquake or the like is shown in FIG.

As shown in FIG. 16, since the upper and lower ends of the rib plate glass 2 are completely fixed to the skeleton 11 in such a conventional example, the skeleton undergoes interlayer displacement due to an earthquake or the like,
When a force in the D direction acts on the upper fixed frame 3a side of the body and a force in the E direction acts on the lower fixed frame 3b side, and the body tilts in the CC direction and is displaced by the displacement amount X, the upper and lower ends of the rib plate glass 2 The same layer displacement amount X as that of the frame 11 is generated in the portion.

On the other hand, the face plate glass 1 receives the inertial force due to the weight of the face plate glass 1 itself as well as the restraint of the sealing material 4 between the face plate glasses 1 adjacent to each other, so that the face plate glass 1 is compared with the interlayer displacement amount X of the frame. The interlayer displacement amount Y of 1 generally tends to be small, that is, as the original phenomenon, the face plate glass 1 and the rib plate glass 2 try to move differently during an earthquake.

However, since the sealing material that joins the face plate glass 1 and the rib plate glass 2 has a high modulus, it opposes the above-mentioned action of attempting different movements, and the face plate glass is not provided at the portions other than the upper and lower end portions. 1 and the rib plate glass 2 try to make the same movement, but as described above, since the upper and lower end portions of the rib plate glass make the same movement as the body, the difference in displacement amount between the face plate glass and the rib plate glass near the upper and lower end portions. Grows larger.

Therefore, the rib plate glass 2 undergoes a substantially S-shaped displacement as shown in FIG. 16, and a large bending load is applied to the rib plate glass 2 at the portions F and G slightly from the center from the upper and lower ends of the rib plate glass 2, The face plate glass 1 and / or the plate glass forming the rib plate glass 2 is often damaged.

The reason why a part of the plate glass is damaged by a large earthquake is considered to be due to the reasons explained above.

The modulus of the sealing material is JIS
When tested by the tensile adhesion test described in A5758, a tensile stress of 50% modulus (refers to a tensile stress when the sealing material has a length increased by 50% from the original length).
High modulus is 4 kg / cm ² or more, medium modulus is 2 kg / cm ² or more 4 kg / cm
Less than ² and low modulus are those of less than 2 kg / cm ² . Here, the sample is a type 2 (H-type) durability test body described in the section of the test piece production of the same JIS, and a plate glass is prepared as an adherend.

In order to solve the above-mentioned problems, a method using a seismic-resistant plate glass construction structure shown in FIG. 17 has been proposed (JP-A-56-3784). FIG. 17 shows a case of the suspension construction method in which the face plate glass and the rib plate glass are hung at the upper part, but the lower frame frame 18 fixed to the rib plate glass 2 and the fixing frame 3 fixed to the frame form a double frame structure. The rib plate glass 2 and the skeleton body are formed so as to be slidable. However, although this method has been confirmed to have a superior performance, it is difficult to spread due to its high cost.

For this reason, it has been desired to develop a large-scale glass screen construction method which has earthquake resistance and is low in cost.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a plate glass construction structure which is not easily damaged by an earthquake or the like.

[0019]

According to the present invention, a plurality of face plate glasses are arranged so that they are flush with each other, and rib plate glasses are arranged in a direction perpendicular to the face plate glasses at the abutting portions of the face plate glasses adjacent to each other, A construction structure of plate glass in which the abutting portions of the face plate glass and the rib plate glass are adhered with a sealing material, and the lower end portions of the face plate glass and the rib plate glass are fitted into the lower fixed frame via the first setting block. In the body, the width in the plate thickness direction of the lower fixed frame of the portion where the rib plate glass is fitted is larger than the width of the first setting block on which the rib plate glass is placed,
Also, there is provided a construction structure for a sheet glass, wherein the sliding means is provided between the first setting block installed at the lower end of the rib sheet glass and the lower fixed frame.

Here, there are a method of suspending the upper end portions of the face plate glass and the rib plate glass and a method of fitting them into the upper fixed frame. In the latter case, the rib plate glass is fitted in the plate thickness direction. The width of the lower fixed frame and the width of the upper fixed frame are larger than the width of the first setting block on which the rib plate glass is placed. The above-mentioned plate thickness direction means the plate thickness direction of the plate glass forming the face plate glass and the rib plate glass.

When a backup material is inserted between the rib plate glass and the lower fixed frame to seal the outside of the backup material, a compressible backup material is inserted,
The outside of the compressible backup material is sealed with a compressible seal material. The same applies to the case where a backup material is inserted between the rib plate glass and the upper fixed frame to seal the outside of the backup material. Foamed neoprene rubber or the like can be used as the compressible back-up material, and a low-modulus silicone-based sealing material such as deamidated or deaminoxy type can be used as the compressible sealant.

With this structure, the rib plate glass can slide in the direction perpendicular to its own surface, that is, in the direction parallel to the face plate glass.

In a preferred embodiment, the sliding means is provided not only between the first setting block installed on the lower end of the rib glass and the lower fixing frame but also on the lower end of the face glass. It is also provided between the setting block and the lower fixed frame. With this configuration, the face plate glass can slide in a direction parallel to its own surface.

Generally, it is sufficient for the face plate glass to be slidable in a direction parallel to its own surface. Therefore, the width of the lower fixed frame and the width of the upper fixed frame in the portion where the face plate glass is fitted are set on the face plate glass. First placed
It is sufficient if the width of the setting block can be set, and it need not be wider than that.

As shown in FIG. 13, two sets of such sheet glass construction structures are prepared, and the face sheet glass arranged at the end of one set of sheet glass construction structures and another set of face sheet glass are orthogonal to each other. Such a combination may be adopted, and the orthogonal corner portions of the both may be joined by a sealing material, and the lower fixed frame and the upper fixed frame may be joined or integrated respectively.

In this case, in order to prevent the face plate glass and the face plate glass at the corners from colliding with each other at the time of an earthquake, only in the corner part, as in the case of the rib plate glass, the face plate glass is fitted in the part. The width of the lower fixed frame in the plate thickness direction (the width of the upper fixed frame is also the same when the upper end of the face plate glass and the rib plate glass are fitted to the upper fixed frame) is the first setting where the face plate glass is placed. When made larger than the block, the face glass can slide in a direction perpendicular to the main surface of the face glass.

In addition, when a backup material is inserted between the face plate glass and the lower fixed frame at this corner portion to seal the outside of the backup material, a compressible backup material is inserted to make a compressible backup. The outside of the material is sealed with a compressible sealing material. The same applies to the case where a backup material is inserted between the face plate glass and the upper fixed frame to seal the outside of the backup material.

The first setting block provided with the sliding means has a cross-sectional shape U having a recess on the upper surface thereof.
It is preferably in the shape of a letter, so that the rib plate glass, or the face plate glass and the rib plate glass can be stably placed.

According to a preferred embodiment, the sliding means has a second setting block provided between the first setting block and the lower fixed frame, the first setting block being the first setting block. It is slidable with respect to the 2 setting blocks.

As a preferred embodiment for making the slide possible, a low friction member is inserted between the first setting block and the second setting block,
The first setting block may be slidable with respect to the second setting block. Alternatively, the mutual contact surfaces of the first setting block and the second setting block may be formed of low friction members, respectively.

The low friction member mentioned here is a member having a small friction coefficient, and for example, a Teflon (fluorine resin: trade name) sheet manufactured by DuPont can be used. Further, in order to form the contact surface of the setting block with a material having a small friction coefficient, a sheet of polytetrafluoroethylene resin (hereinafter referred to as fluororesin) may be attached to the contact surface portion of the setting block.

The first setting block and the second setting block may be entirely formed of a low friction member such as fluororesin or high strength polycarbonate.

According to another preferred embodiment, the sliding means has a plurality of bearing members inserted between the first setting block and the lower fixed frame.
The bearing material may be spherical or cylindrical.

It is more preferable that a convex edge is formed on the lower surface of the first setting block so that the bearing material does not fall off from the first setting block.

EXAMPLE FIG. 2 is a view showing one construction structure of a sheet glass of the present invention.
FIG. 3 is a perspective view of an essential part of the embodiment, in order to support the face plate glasses 1 and 1 forming the wall surface from the direction perpendicular to the back surface, rib plate glasses 2 are provided at these abutting parts so as to be juxtaposed behind them and the abutting parts are formed. It is sealed with a high modulus sealing material 4. The lower end portions of the face plate glass 1 and the rib plate glass 2 are fixed by a lower fixed frame 3b, and the upper end portions are similarly fixed by an upper fixed frame 3a (not shown).

In FIG. 2, the lower fixing frame 3b is shown so that it can be seen directly. However, in reality, the lower fixing frame 3b is hidden by the floor material and cannot be seen directly, as will be described later. Similarly,
The upper fixed frame 3a is hidden by a ceiling wall (not shown) and cannot be seen directly.

Both the face plate glass 1 and the rib plate glass 2 are supported by the lower fixed frame 3b receiving the own weight of the glass. The upper fixed frame 3a and the lower fixed frame 3b are collectively referred to as a fixed frame. The rib plate glass 2 is slidable in the I direction in the figure. Further, in this example, the face plate glass 1 is configured not to be slidable, but it is preferable to be configured to be slidable in the I direction in the figure, as described later.

FIG. 1 shows the construction A of the plate glass construction structure of FIG.
It is a principal part sectional drawing which concerns on a part, and shows the sectional drawing of the lower end part of rib plate glass.

The lower fixed frame 3b is attached to the body 11 and installed so as to be hidden by the floor material 10.
In the lower fixed frame 3b, a setting block (first setting block) 5 having a substantially U-shaped cross section installed at the lower end of the rib plate glass 2 has a second setting through two sliding members 7a and 7b. It is placed on top of block 6. Reference numeral 12 is a spacer. Reference numeral 21 is a sliding means, and in this example, the sliding means 21 is composed of two sliding members 7a and 7a.
b and the second setting block 6.

The first setting block 5 has a concave portion 22 on the upper surface thereof, and the edge portion of the rib plate glass 2 is fitted into the concave portion 22. The inner width N of the lower fixed frame 3b is set so that the first setting block 5 having the width K can slide left and right in the I direction by the width L and the width M (N = K + L + M). The width L and the width M are appropriately determined in consideration of the magnitude of interlayer displacement occurring in the body.

A foamable neoprene rubber 9 which is a compressible backup material is filled between the rib plate glass 2 and the lower fixed frame 3b, and the outside thereof is sealed by a low modulus silicone sealant 8 which is a compressible seal. ing. When the rib plate glass 2 is deformed in the out-of-plane direction, the rib plate glass 2 is bent and deformed by sliding on the second setting block 6 in the I direction (that is, in the lower fixed frame 3b in the I direction). Can be prevented.

It is desirable to use a fluororesin sheet or the like for the sliding members 7a and 7b, but the U-shaped setting block (first setting block) 5 and the second setting block 6 are made of fluororesin or high strength polycarbonate. If it is made of a material with a small friction coefficient, the sliding material 7
a and 7b can be omitted.

Although not shown, the inner width of the upper fixed frame 3a in which the rib plate glass 2 is fitted is also lower.
Foamed neoprene rubber (compressible backup material) 9 is filled between the rib plate glass 2 and the upper fixed frame 3a and has a low modulus silicone sealant (compressible seal). Material 8 is sealed.

According to the configuration of the present invention, it is considered that the frame is not duplicated as compared with the method shown in FIG.

FIG. 3 is an explanatory view of a state of deformation occurring in the face plate glass and the rib plate glass when the plate glass construction structure of FIG. 2 undergoes interlayer displacement due to an earthquake or the like. As shown in FIG. 3, when the frame is subjected to interlayer displacement due to an earthquake or the like, a force in the D direction acts on the upper fixed frame 3a side of the frame and a force in the E direction acts on the lower fixed frame 3b side, and the frame moves in the CC direction. It is inclined to and deformed by the amount of interlayer displacement X.

On the other hand, since the face glass sheets 1 and 1 are subjected to the restraining force of the high modulus sealing material 4 and the inertial force due to the weight of the face glass sheet itself, the interlayer displacement amount Y of the face glass sheets 1 and 1 is calculated as follows. It is smaller than the displacement amount X.

As described above, the rib plate glass 2 is adhered to the face plate glasses 1 and 1 by the above-mentioned high-modulus sealing material 4, and is attached to the upper fixing frame 3a and the lower fixing frame 3a fixed to the frame 11. Since it is slidable with respect to the rib plate glass 2, the interlayer displacement amount of the upper and lower end portions of the rib plate glass 2 is equal to the interlayer displacement amount of the face plate glass Y.
And becomes smaller than the interlayer displacement amount X of the skeleton. Therefore, since the interlayer displacement amounts of the face plate glass 1 and the rib plate glass 2 are equal, an unnecessary bending load is not generated in the rib plate glass.

According to the present invention, since the sliding means is provided between the first setting block installed at the lower end portion of the rib plate glass and the lower fixing frame fixed to the skeleton, the rib is provided. Even if the skeleton of the plate glass undergoes interlayer displacement, the plate glass is displaced integrally with the face plate glass, and the interlayer displacement amount of the face plate glass and the interlayer displacement amount of the rib plate glass become equal, so that an unnecessary bending load does not occur in the rib plate glass.

For example, when the setting block installed under the rib plate glass has a double structure including the first setting block and the second setting block, the ribs can be removed when an interlayer displacement occurs in the skeleton due to an earthquake or the like. Since the setting block on which the plate glass is placed can slide on the body and follow the face plate glass, bending deformation does not occur in the rib plate glass, and the earthquake resistance is improved.

Further, by inserting a sliding material such as a fluororesin sheet between the setting blocks or by making the setting block having a small friction coefficient such as fluororesin or high strength polycarbonate, it becomes easier to slide and seismic resistance is improved. Can be improved.

Alternatively, a bearing material may be provided between the first setting block and the lower fixed frame so that the rib block can slide with respect to the lower fixed frame.

It is more preferable that sliding means is also provided between the face plate glass and the lower fixed frame so that the face plate glass can slide in a direction parallel to the surface of the face plate glass itself. It will not occur and the earthquake resistance will be further improved.
