[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting bolt which is inserted into each of a plurality of wall panels in order to mount the plurality of wall panels vertically and horizontally on a structure. A fixed side having a metal fitting body that supports the plurality of mounting bolts, a holding member holding and holding the plurality of wall panels between the mounting bolt and the metal fitting body, and a fastener fixed to the structure The present invention relates to a wall panel mounting bracket connected to a member.

[0002]

2. Description of the Related Art In general, when a wall of a structure is formed of a wall panel such as a curtain wall or a glass panel, a method of attaching and fixing these wall panels to the structure using bolts is known. is there. For example, when one wall panel is attached and fixed, bolt insertion holes are provided in the vicinity of the four corners of each wall panel, and mounting bolts are inserted from one side of the wall panel to the bracket body fixed to the structure side. This mounting bolt is attached by screwing. These wall panels must withstand wind pressure and the like. If the shape of the wall panel is close to a square and the dimensions are not so large, it is possible to satisfy the design wind pressure and the like simply by supporting the support points at the four corners. However, when the size of the wall panel is large, or when it is rectangular and the ratio of the lengths of the long sides is large, or when the design wind pressure determined by the given conditions is large, the four-point support is used. The structure may not be able to satisfy the required design wind pressure. For example, FIG. 2 shows a deformation state of the wall panel when viewed in a direction parallel to the wall panel surface. As shown in FIG. 2, when the deformation of the wall panel becomes excessive, There is a possibility that breakage may occur at the location. Conventionally, in order to prevent such damage due to excessive deformation, measures have been taken by increasing the thickness of the wall panel or increasing the number of intermediate support points in the middle of each side. Rather, providing the latter intermediate support point is more effective in that the weight of the entire panel wall surface can be prevented and the strength of the individual wall panel mounting brackets does not need to be increased.

[0003]

However, even if such an intermediate support point is provided and supported, the following problems have conventionally occurred because each metal fitting body is rigidly joined to the structure. For example, when a large wind pressure is applied to a rectangular panel wall provided with an intermediate support point, the panel wall deforms as shown in FIG. In the case of FIG. 3, the bending moment applied to the wall panel is almost zero at the corner support point and becomes maximum at the middle support point. Normally, a cushioning member such as a washer is interposed between the wall panel and a bolt for attaching the wall panel. Therefore, since a kind of pin connection is formed at the corner support point, even if the wall panel is bent and deformed, the wall panel is hardly bent at the corner support point. Does not occur. On the other hand, at the intermediate support point, even if it is in a pin-joined state, since the surfaces on both sides thereof are deformed, a bending moment is always applied to the intermediate support point. If the bending moment is excessive, the wall panel may be broken at the intermediate support point. As described above, even when the intermediate supporting points are provided on the peripheral edge of the wall panel, there is room for improvement in the mounting method of the wall panel. An object of the present invention is to provide a wall panel mounting bracket capable of reducing the stress generated at such an intermediate support point and mounting the wall panel in a state where the wind pressure is increased.

[0004]

In order to achieve this object, the wall panel mounting bracket according to the present invention is characterized in that a holding member for sandwiching and holding the wall panel is fixed to a fixed member on the structure side. A point holding mechanism which is movable in an out-of-plane direction of the wall panel and has elasticity so as to buffer the movement of the holding side member. The wall panel mounting bracket, the bracket body of the holding side member, a plate-shaped body, and a plurality of panel contact body fixed to the plate-shaped body and through which the mounting bolt is inserted, The plate-shaped member is provided with a holding column extending toward the structure, and the position holding mechanism is configured to move the plate-shaped member so that the plate-shaped member is movable along the axis of the column. A configuration in which two helical springs are arranged so as to be able to move along the axial direction of the holding column, and to be in contact with both sides of the fastener in the axial direction of the holding column. You may. Further, the wall panel mounting bracket has a configuration in which the plate is fixed to the fastener, and the position holding mechanism is configured such that at least one of the plate and the fastener itself is elastically deformed. You may.

[0005]

The characteristic features of the wall panel mounting bracket of the present invention have the following effects. The position holding mechanism provided on the wall panel mounting bracket of the present invention is configured such that the holding-side member is movable in an out-of-plane direction of the wall panel, and buffers this moving operation. Has functions. The position holding mechanism is configured using, for example, two rubber annular bodies or two helical springs.
That is, a part of the holding-side member is formed into a plate-like body, and a holding column is provided to extend from the plate-like body toward the structure. The holding column, with respect to the fastener as a fixed member,
The wall panel is connected so as to be movable in an out-of-plane direction. In this movement direction, the two rubber annular members or the elastic members such as the two helical springs are arranged on both sides of the plate member, and the plate members are balanced by the contact force of both elastic members. Can be held. With this configuration, for example, it is easy to set the spring constants of the two helical springs according to the bending characteristics of the wall panel to be held. Further, the position holding mechanism may be configured such that a member constituting the holding side member or the fixed side member itself is elastically deformed. For example, if the plate-like body and the fastener are firmly connected and at least one of the members is elastically deformable, the supported wall panel can be moved in an out-of-plane direction.

[0006]

As described above, when the wall panel mounting bracket of the present invention is used particularly at the intermediate support point, the bending moment generated at the intermediate support point of the wall panel can be reduced. As shown in FIG. 4, if the wall panel mounting bracket of the present invention is used, the bending deformation of the entire wall panel and the local bending deformation at the intermediate support point are intermediate between the state of FIG. 2 and the state of FIG. State can be suppressed. Therefore, in a structure in which the wall panel is supported by bolts, even a thin wall panel having a large peripheral length can be supported at each supporting point without generating cracks or the like.
When the position holding mechanism is formed using a helical spring, the spring constant can be freely set. Therefore, it is possible to provide a wall panel mounting bracket having an optimum function according to the bending characteristics of the wall panel to be supported. That is, the degree of bending deformation of the entire wall panel and the degree of local bending deformation at the intermediate support point when wind pressure or the like acts can both be kept within allowable ranges. When the position holding mechanism is formed by elastic deformation of the member itself, the structure itself of the wall panel mounting bracket can be simplified. For this reason, transparency is particularly important when a glass panel is used as the wall panel, but the appearance of the wall panel mounting bracket itself can be simplified, which is advantageous in terms of visibility.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A wall panel mounting method and a position holding mechanism D according to an embodiment of the present invention will be sequentially described with reference to the drawings.

FIG. 5 shows a vertically elongated rectangular wall panel P.
Are shown in parallel when mounted side by side with the mounting bolts 5 vertically and horizontally. The wall panel P may be, for example, any of a glass panel, a resin panel, a wood panel, a stone panel, a cement panel, and other panels, and these are collectively referred to. In order to support the wall panel P by passing the mounting bolts 5 through one wall panel P, each corner has a corner support point C.
However, an intermediate support point M is provided at an intermediate position of the long side. The wall panel P is fixed to a structure by supporting these support points C and M with wall panel mounting brackets.

The wall panel mounting bracket is, in principle,
The shape that supports the corner support point C and the shape that supports the intermediate support point M are different. That is,
At the corner support point C, one wall panel mounting bracket supports four wall panels P, while at the intermediate support point M, one wall panel mounting bracket has two adjacent panel panels. The wall panel P is supported.
The wall panel mounting bracket for the corner support point C and the one for the intermediate support point M are both fixed side members F
And the holding side member H. The fixed side member F is a member for mounting the wall panel mounting bracket on the structure side, and the holding side member H is a member for holding the wall panel P.

FIGS. 1A and 1B show the intermediate support point M
1 shows an example of a wall panel mounting structure. The fixed side member F is mainly composed of the fastener 2. The fastener 2 is attached to a wall support column 1 provided on the structure side. Although not shown, the fastener 2 can be attached to the wall support column 1 so as to be freely retractable by having a threaded structure or the like. On the other hand, the holding side member H
Are mainly composed of mounting bolts 5, metal fittings X, holding columns 7, and the like. The metal fitting body X further includes a plate-like body 3, a panel contact body 4, and the like. At an intermediate support point M of the wall panel P, a bolt insertion hole 6 for inserting the mounting bolt 5 is provided. In the bolt insertion hole 6, a counterbore portion 6 is provided on a side opposite to the wall panel mounting bracket.
A is formed. On the other hand, an enlarged head 5A is formed at one end of both ends of the mounting bolt 5, and a first screw portion 5B is formed at the other end. The mounting bolt 5 is inserted into the bolt insertion hole 6, and further, the panel contact body 4 and the annular insertion hole of the plate-shaped body 3 are inserted, and then fastened with the first nut N <b> 1. That is, the wall panel P is sandwiched between the enlarged diameter head 5A of the mounting bolt 5 and the panel contact member 4. In this state, the head of the mounting bolt 5 fits substantially in the same plane as the surface of the wall panel P. A nylon washer W1 is interposed between the enlarged diameter head 5A and the counterbore 6A to buffer the mounting bolt 5 and the wall panel P. Similarly, a fiber board W2 is interposed between the panel contact member 4 and the wall panel P as a cushioning material. Further, between the panel contact member 4 and the plate-like body 3, and between the plate-like body 3 and the first nut N
1, a seat ring W3 is interposed to reduce the frictional force between these members. With the seat ring W3 interposed, the mounting bolt 5 can be easily moved in the in-plane direction of the plate-like body 3. Therefore, even if the structure is deformed during an earthquake or the like, the influence of the deformation does not affect the wall panel P. An elastic joint material m is filled between the adjacent wall panels P for the purpose of waterproofing or the like. The holding member H and the fixed member F are connected via the position holding mechanism D. The position holding mechanism D will be described later.

One example of a method of supporting the wall panel P at the corner support point C is shown in FIGS. In principle, one wall panel P is supported at only the upper two points or the lower two points of the four corner support points C. This is because there is some error in the position of each of the wall panel mounting brackets attached to the structure, so that the load is equally applied to the support points C and M of one wall panel P. It is very difficult and it is not necessary. The fastener 2 as the fixed member F is attached to the wall support column 1 on the structure side. For the fastener 2, the holding side member H
Is connected to the holding column 7 and the plate-shaped body 3.

In the wall panel mounting bracket used at the corner support point C, the plate 3 has a substantially cross shape. The four end portions of the plate-like body 3 have square insertion holes 1 through which the mounting bolts 5 pass.
3A are provided respectively. The four rectangular insertion holes 1
3A is arranged such that the center position of each of the rectangular insertion holes 13A is located at the vertex of a substantially square when viewed in the same direction as the axis of the mounting bolt 5. The square insertion hole 1
3A is formed in a square hole when viewed in the same direction as the axis of the mounting bolt 5. The length of one side of the square hole is set to be larger than the outer diameter of the mounting bolt 5. Therefore, inside the square insertion hole 13A, the mounting bolt 5 is movable in the radial direction.
The corners of the square insertion holes 13A are rounded as shown in FIGS. A bolt support member 14 for supporting the mounting bolt is mounted on one of the four sides forming the square insertion hole 13A. The bolt support member 14 has a bolt receiving surface 14A and an engaging projection 14B. On the other hand, an engagement recess 15 is formed in the middle of each side of the square insertion hole 13A. The bolt support member 14 is attached to one of the lower sides of the four sides forming the square insertion hole 13A by engaging the engagement protrusion 14B with the engagement recess 15. As a result, the mounting bolt 5 is positioned at the center of the square insertion hole 13A while the bolt receiving surface 1
4A. FIG. 7 shows a state in which the bolt supporting member 14 is attached to the lower two of the four square insertion holes 13A. Accordingly, one wall panel P is suspended and supported by only the upper two points of the four corner support points C. Therefore, at the two lower corner support points C, the wall panel P is merely prevented from moving out of the plane. Although not shown, the bolt support member 14 is attached to the upper two of the four rectangular insertion holes, and lifted at the two lower corner support points C of the wall panel P. The supporting structure may be adopted.

The wall panel mounting bracket of the present invention exerts its effect particularly when used at the intermediate support point M. The wall panel mounting bracket includes a position holding mechanism D for buffering out-of-plane deformation of the wall panel P at a connection portion between the holding member H and the fixed member F. Details of the position holding mechanism D will be described with reference to FIG. The fastener 2 as the fixed member F is fixed to the wall supporting column 1 on the structure side. The fastener 2 is bent at an intermediate portion, and the opposite end of the fastener 2 on the non-fixed side is substantially parallel to the wall panel P to be attached.
The holding-side member H mainly includes a mounting bolt 5, a plate-like body 3, the holding column 7, and the like. A cylindrical insertion hole 13 through which the mounting bolt 5 is inserted is provided at both ends of the plate-like body 3.
B is formed. However, the hole shape of the insertion hole is not particularly limited because the intermediate support point M does not bear the weight of the wall panel P. The holding column 7 is arranged so that the wall panel P
Is a direction substantially perpendicular to and extends toward the structure. A flange 7A is formed at an intermediate portion in the longitudinal direction of the holding column 7, and a second screw portion 7B is formed at an end of the both ends of the holding column 7 on the side attached to the fastener 2. The holding column 7 is inserted into the slide opening 2A provided in the fastener 2 from an end on the side of the second screw portion 7B, and the second screw portion 7B is fastened by a second nut N2. At this time, between the flange 7A and the fastener 2 and between the fastener 2 and the second nut N2
An elastic material such as rubber is inserted between the two.

When no load is applied to the wall panel P in the out-of-plane direction, the holding column 7 is at a neutral position with respect to the fastener 2. In contrast,
When an external force such as wind pressure is applied to the wall panel P, the holding column 7 is displaced toward the structure with respect to the fastener 2. However, since the elastic force of the elastic material acts on the change of the holding column 7, the holding column 7 is displaced by a certain distance and stops. That is, as shown in FIG. 4, when pressure or the like is applied, the entire wall panel bends and deforms in a substantially concave shape, and the intermediate support point M of the wall panel P is shifted from the corner support point C by the structure Displace to the object side. As a result, the bending moment generated at the intermediate support point M is smaller than when the intermediate support point M does not retreat at all. This is because the deformation of the entire wall panel P causes the respective portions of the panel to share and support the wind pressure, so that the supporting force to be borne at the intermediate support point M is reduced. Therefore, the chance of the wall panel P being damaged at the intermediate support point M is extremely reduced.

As the elastic material, for example, an annular member G made of rubber may be used as described above, or as shown in FIG.
A member such as a helical spring S may be used. The use of the rubber annular member G is advantageous in that the configuration of the position holding mechanism D is greatly simplified and cost can be reduced. On the other hand, when the helical spring S is used, since the size or the spring constant can be set arbitrarily, a wall panel having an optimal function according to the bending characteristics of the wall panel P to be supported and the like. A mounting bracket can be provided. In other words, when wind pressure or the like acts, the degree of bending deformation of the entire wall panel, and the degree of local bending deformation at the intermediate support point,
It can be surely kept within the allowable range.

[Other Embodiments] The Position Holding Mechanism D
As the elastic material, the fixed side member F or the holding side member H itself may be made of an elastically deformable member in addition to the rubber annular member G or the helical spring S. For example, at least one member of the fastener 2 or the plate-like body 3 is formed of a leaf spring or a helical spring, an elastic member such as rubber or synthetic resin. FIG. 9 shows an embodiment in which the fastener 2 is constituted by a leaf spring. In this case, by appropriately combining the spring constant, the plate thickness, the plate width, and the like of the fastener 2, a position holding mechanism D having an optimal function according to the bending characteristics of the wall panel P to be supported is obtained. be able to. Further, if the position holding mechanism D is configured by elastic deformation of the member itself, the configuration itself of the wall panel mounting bracket can be simplified. In particular, when a glass panel is used as the wall panel, its transparency is important. However, if the appearance of the wall panel mounting bracket itself is simplified, it is advantageous in terms of visibility.

There is no problem even if the wall panel mounting bracket of the present invention is used at the corner support point C. The panel wall formed by the wall panel P may be an outer wall or an inner wall. In addition, the member on the structure side is not limited to the wall supporting column 1, but may be a slab, a beam, or the like. In short, any structure that can support the wall panel P may be used.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the attached drawings.
