Description

  In the present invention, the inner side of the frame is partitioned into a plurality of rectangular openings by a metal or non-metallic frame material arranged in a lattice shape, and a plate material is fitted and closed in each of the openings. It relates to a certain wall structure.

In the above wall structure, the inside of the frame is partitioned into a plurality of quadrangular openings with a metal or non-metallic frame material arranged in a lattice shape, and a plate material is fitted into each of the openings to close it. Therefore, in-plane deformation of the wall surface due to horizontal external force such as wind or earthquake acting on the frame, for example, two corners facing each other along one diagonal line in the rectangular frame are close to each other, and the remaining High strength is achieved by restricting the deformation of the two corners away from each other by restricting the deformation of the opening by contacting the frame material accompanying the deformation of each opening and the plate material fitted in the opening. This can be prevented without using a frame or a frame material.
However, when a glass sheet is fitted into at least some of the plurality of openings so that the transparency of the wall can be secured, conventionally, an external force in the direction along the glass surface acts on the glass sheet. Then, considering that the stress tends to concentrate on a part of the surface glass, and as a result, the surface glass is easily damaged due to cracks generated at the stress concentration location, the surface glass is fitted to the opening as a building structural member. In order to prevent the external force from acting on the surface glass as much as possible even if a horizontal external force is applied to the frame, it is fitted into the opening through an elastic cushioning material (conventional use). Technology and cannot disclose prior art document information).

For this reason, in order to ensure the transparency of the wall, when the surface glass is fitted into at least some of the openings, the deformation of the opening is restricted to the surface glass. There is a drawback that the function cannot be expected and the wall as a whole cannot be expected to have a high yield strength.
The present invention has been made in view of the above circumstances, and even if a surface glass is fitted into at least some of the plurality of rectangular openings so as to ensure the transparency of the wall, the surface The purpose is to enable the deformation of the opening into which the glass is fitted to be restricted by the surface glass, and to prevent in-plane deformation of the wall surface without using a particularly strong frame or frame material. To do.

  In the first characteristic configuration of the present invention, the inside of the frame is partitioned into a plurality of rectangular openings by a metal or non-metallic frame material arranged in a lattice shape, and a plate material is provided for each of the openings. It is a wall structure that is fitted and closed, and the frame material is arranged in a lattice shape in a posture inclined with respect to the vertical, and adjacent openings sandwiching the frame material are inclined with respect to the vertical. Adjacent to the direction in which the plate member is fitted into at least a part of the plurality of openings, a substantially flat surface glass as the shape of the opening is employed, and more than the surface glass and the frame material. A spacer that is soft and capable of transmitting an external force across the frame material and the face glass is mounted between the end face along each side of the face glass and the frame material.

[Action and effect]
Since at least a part of the plurality of openings is fitted with a rectangular surface glass having substantially the same shape as the opening, the transparency of the wall can be ensured.
A spacer that is softer than the face glass and the frame material and that can transmit an external force between the frame material and the face glass is mounted between the end face along each side of the face glass and the frame material. Since the surface glass is fitted, the compression force is mainly applied to the surface glass without stress concentration through the spacer from the frame material forming the opening as the opening is deformed. Thus, the deformation of the opening can be regulated based on the compressive strength of the face glass.
However, as in the comparative example illustrated in the conceptual diagram of FIG. 6 (a), the frame material 1a is arranged in a lattice shape along the vertical direction and the horizontal direction, and the inside of the quadrangular frame body 8 is plurally arranged. For example, when the rectangular surface glass 3 which is substantially the same as the shape of the opening 2c is fitted into the opening 2c along the diagonal lines m and n in the frame 8 as shown in FIG. As shown in (b), two external corners D1 facing each other along one diagonal m are brought close to each other by a horizontal external force F acting on the upper part of the frame 8 with the lower part of the frame 8 fixed. As the frame body 8 tries to deform so that the remaining two corner portions D2 are separated from each other, the compression external force Fc in the direction in which the two corner portions D1 are close to each other is a diagonal line in the surface glass 3. Around corner C1 along m As a result, in the corner portion C1 of the surface glass 3, cracks are likely to occur inside the thickness due to the shearing force acting in the direction along the glass surface within the thickness of the surface glass 3. There's a problem.
Therefore, in the present invention, as illustrated in the conceptual diagram of FIG. 5 (a), the frame material 1a is arranged in a lattice shape in a posture inclined with respect to the vertical, and the inside of the frame body 8 has a plurality of quadrangles. For example, the rectangular surface glass 3 having substantially the same shape as the opening 2a is fitted into each opening 2a along each diagonal line m, n in the frame 8 as shown in FIG. As shown in (b), two external corners D1 facing each other along one diagonal m are brought close to each other by a horizontal external force F acting on the upper part of the frame 8 with the lower part of the frame 8 fixed. As the frame body 8 is deformed so that the remaining two corner portions D2 are separated from each other, a compression external force Fc in a direction in which the two corner portions D1 tend to approach each other is applied to the corner of the surface glass 3. In order not to concentrate on part C Easily dispersed along the end face 20 along the sides of the 3, cracks inside thick at the corner portion C of the surface glass 3 there is little possibility to occur.
Accordingly, in order to ensure the transparency of the wall, even if the surface glass is fitted into at least a part of the plurality of rectangular openings, the deformation of the opening in which the surface glass is fitted is changed to the surface glass. It is possible to regulate the wall surface, and in-plane deformation of the wall surface can be prevented without particularly using a high strength frame or frame material.

  A second characteristic configuration of the present invention is that the spacer is mounted so as to be separated from a corner portion of the surface glass.

[Action and effect]
Since the spacer is mounted away from the corner of the surface glass, it can be prevented that compression external force acts on the corner of the surface glass through the spacer from the frame material. There is less risk of internal cracking.

  A third characteristic configuration of the present invention is that the spacer is mounted at a distance of 25.4 mm (1 inch) or more from the corner portion.

[Action and effect]
The spacer is mounted at a distance of 25.4 mm (1 inch) or more from the corner portion of the face glass so that the compressive external force does not concentrate on a narrow area around the corner portion of the face glass. In addition, it is possible to ensure a large breaking load of the surface glass accompanying the deformation of the frame.
