[0003]

By mounting the wall panel so that it can move relative to the structure within a certain range, the stress at the time of occurrence of an earthquake or strong wind is applied to the wall panel mounting portion. It is already known that concentration can be reduced, but according to the above-described conventional wall panel support structure, the rod-shaped portion 2a and the outer fitting portion 31 are arranged in the longitudinal direction of the first mounting portion 2 in the longitudinal direction. Are fitted so as to be relatively movable along each other, to be relatively rotatable about each other's axis, and to be pivotally movable such that one end of the rod-shaped portion is close to and separated from each other along the wall panel thickness direction. Therefore, it is possible to relatively move in these directions, but it is difficult to reduce the movement of the wall panel swinging along the wall surface. Such movement between the first mounting part and the second mounting part occurs when a roll of earthquake occurs, and if this movement cannot be mitigated, stress concentration occurs at the mounting part of the wall panel. As a result, there is a problem that the wall panel and the fixture are broken or fall off.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems, and it is difficult for stress concentration to occur at a mounting portion of a wall panel even when an earthquake or a strong wind occurs, and the wall panel is kept in a stable state. Is to provide a wall panel support structure capable of supporting the wall panel.

[0005]

According to a first aspect of the present invention, as shown in FIGS. 4 to 22, a wall panel P can be freely attached to a structure A via an attachment 1. A second mounting portion 1A which is provided on the first mounting portion 2 and a third mounting portion 1B which is freely mounted on the wall panel P.
Are provided on the attachment 1, the second attachment 1A is attached to the first attachment 2, and the third attachment 1B
Is attached to the wall panel P, so that in the wall panel support structure in which the wall panel P is supported by the structure A, one of the first mounting portion 2 and the second mounting portion 1A is An outer fitting portion 3b having a lateral dovetail groove 6 capable of receiving the other of the first mounting portion 2 and the second mounting portion 1A, and the first mounting portion 2 and the second mounting portion 1A. 1A
The other is provided with a bar-shaped portion 2a that is horizontally long in the direction along the wall surface and is freely fit in the dovetail groove 6, and a connecting portion 2b that is integrally connected to the rod-shaped portion 2a through the opening 6a of the dovetail groove 6. The rod portion 2a and the outer fitting portion 3b are relatively movable along the longitudinal direction of the rod portion 2a, and
It is relatively rotatable relative to each other around its axis, and is relatively swingable along the wall surface, and is relatively swingable so that one end of the rod-shaped portion 2a is close to and separated along the wall panel thickness direction. And the outer fitting portion 3b in the fitted state.
Is located in a state where the opening 6a of the dovetail groove 6 faces in any direction of approaching or separating from the wall surface. According to the characteristic configuration of the invention of claim 1, one of the first mounting portion and the second mounting portion is an outer fitting portion provided with a dovetail groove arranged in a horizontal direction, and the other is the horizontally elongated bar-shaped portion. , And the connecting portion, wherein the rod portion and the outer fitting portion are relatively movable along the longitudinal direction of the rod portion, and are relatively rotatable about each other's axis. The rod-shaped portion is fitted so as to be relatively swingable along a wall surface, and one end of the rod-shaped portion is relatively swingable so as to approach and separate along the wall panel thickness direction. The wall panel supported along the surface can slide left and right along the wall, can swing around the connection point in a state where the wall faces diagonally upward or downward, and can be viewed from the front of the wall. , Can swing clockwise or counterclockwise around the connection point, or the vertical axis including the connection point It is possible to swing around. Of course, when the initial mounting state of the wall panel is inclined from the vertical plane, a similar movement can be expected based on the initial state. Therefore, while maintaining the support state of the wall panel, it becomes possible to allow movement in more directions, and stress concentration is less likely to occur at the mounting point between the structure and the wall panel. In the event of occurrence, the wall panel can be supported without difficulty. As a result, the support state of the wall panel is simplified and the stress generated in the wall panel can be reduced, so that even if an earthquake or strong wind occurs, the wall panel can be stably maintained. It becomes possible to support. Furthermore, the installation position of the first mounting portion, the second mounting portion and the third mounting portion,
Even if the position is slightly displaced due to the situation at the site, the displacement can be absorbed by the relative movement, rotation, swing, etc. of the rod-shaped portion and the external fitting portion. The installation work of the body panel does not take much time, and it is possible to proceed smoothly and quickly. Further, since the outer fitting portion in the fitting state with the rod-shaped portion is installed in a state in which the opening of the dovetail groove is directed to any one of the directions of approaching and separating from the wall surface, the outer fitting portion itself has the dovetail opening. Other parts can bear the stress as a continuous member, and the force acting between the external fitting part and the rod-shaped part can be received by the continuous member part. In particular, when a force in the direction of pulling out the wall panel from the structure is applied, the rod-shaped portion and the dovetail-opening back side portion are received by contact with each other,
Regarding the stress condition in the outer fitting portion, the stress can be equally received by the continuous members (both side walls of the dovetail groove) located on both sides of the rod-shaped portion. Therefore, compared to the conventional one (where the dovetail opening is directed downward and the stress is only borne within the cross section of the member where the bottom of the dovetail groove of the outer fitting portion is small), the force for detaching the wall panel is higher. The resistance to the action of increases, it is possible to exhibit a stronger wall panel support force, or when expecting the same support force as before, by reducing the member cross section of the outer fitting portion, It is possible to reduce the size of the fixed portion of the wall panel. Furthermore, by providing the dovetail groove in the state where the opening direction is set in the outer fitting portion as described above, the connecting portion is connected to the opening of the dovetail groove in a state where the rod-shaped portion is fitted in the dovetail groove. Because it can be located, the connection structure between the rod-shaped portion and the connecting portion, for example, to provide a connecting portion at the center of the rod-shaped portion, or to provide a connecting portion at both ends of the rod-shaped portion, or, To provide a connecting portion at one end of the rod-shaped portion, or to provide a connecting portion over the entire length of the rod-shaped portion,
In any case, the relative movement between the external fitting portion and the rod portion can be allowed. Therefore, the freedom of design such as the arrangement and posture of the connecting portion is improved, and the aesthetic appearance can be improved. Further, since the opening direction of the dovetail groove is set in a state of being in any of the directions of approaching and separating from the wall surface, the member length of the connecting portion itself is shorter than that of the conventional one, which is advantageous in terms of stress. State.

As shown in FIG. 1, the third mounting portion 1B penetrates a vertical joint between adjacent wall panels P to form an edge of both wall panels P. It is formed so that it can be clamped. According to the characteristic configuration of the second aspect of the present invention, in addition to the effect of the first aspect of the present invention, it is possible to achieve the effect of the first aspect of the present invention, and further, compared with the case where the third mounting portion is penetrated and mounted on the wall panel. It is possible to support the panel in a state where the strength of the panel is small.
As a result, it is possible to withstand a larger external force (external force acting on the wall panel).

The feature of the invention according to claim 3 is shown in FIGS.
As shown in the example, the rod-shaped portion 2a has a columnar shape, and the dovetail groove 6 has an inner peripheral surface formed in a trumpet shape so as to have a larger diameter toward both ends. Claim 3

Furthermore, at the time of relative swing between the rod-shaped portion and the outer fitting portion, the mutual contact portions are easily moved gradually, and it is possible to allow a smooth swing, and the contact portions are always the same. As compared with the above, it is possible to reduce local wear, and it is possible to improve the durability of parts.

As shown in FIG. 5, a characteristic configuration of the invention according to claim 4 is that the length of the rod-shaped portion 2a is set to be larger than the length of the dovetail groove 6, and the connecting portion is connected to the central portion thereof. Where the portion 2b is provided. According to the characteristic configuration of the fourth aspect of the invention, in addition to the effect of any one of the first to third aspects of the invention, when the rod-shaped portion and the outer fitting portion slide relative to each other, Are not easily disengaged, and a complicated bending moment is less likely to act on the connecting portion, so that the wall panel can be supported in a stable state.
