JP 2009-102869 A

For environmental reasons, solar panels are increasingly being installed on the rooftops of buildings. Separately, vibration control devices may be installed on the rooftop of a building as a measure against environmental vibrations such as traffic vibrations and wind vibrations. If solar panels have already been installed over the entire rooftop at the time the vibration control device is installed, it is possible to remove some of the solar panels and install the vibration control device in the area freed up by the removal. However, this is problematic because the existing solar panels are wasted. It is also problematic because the building's power generation capacity is reduced.

In the vibration-controlled building described in Patent Document 1, solar panels are used as weight elements. This allows for both the installation of solar panels and vibration control of the building. However, when solar panels are used as weight elements, there are cases where the weight is insufficient and sufficient vibration control effect cannot be obtained. In addition, because the solar panels are installed via energy absorbing members, there are cases where the connection strength of the respective connections between the solar panels, energy absorbing members, and roof cannot be sufficiently ensured during earthquakes or storms. As a result, sufficient vibration control performance may not be achieved.

From the above perspective, it is desirable to provide a building in which vibration control performance is ensured when solar panels are properly installed, and in which there is no need to reduce the capacity of the solar panels.

The present invention was made in consideration of the above situation, and its purpose is to provide a building in which vibration control performance is ensured when the solar panels are properly installed, and in which there is no need to reduce the capacity of the solar panels.

The building according to the present invention for achieving the above object comprises:
A solar panel;
A support portion extending above the roof from the rooftop beam, and a platform beam suspended between the pair of support portions;
A panel frame that is suspended between the pair of mounting beams and supports the solar cell panel;
A vibration control device is provided between the pair of frame beams,
The vibration damping device is disposed between the pair of panel frames and below the solar cell panel.

The building according to the present invention further comprises:
The vibration damping device may overlap the solar cell panel when viewed from above.

The building according to the present invention further comprises:
The panel frame is supported on an upper surface of the frame beam,
The vibration damping device may be supported by a lower portion of the frame beam.

The building according to the present invention further comprises:
The frame beam has a connection plate that supports the vibration damping device,
The connection plate may be supported by a lower portion of the frame beam.

The building according to the present invention further comprises:
The connecting plate may have a reinforcing portion extending from a surface of the connecting plate.

It is possible to provide a building in which vibration control performance is ensured when the solar panels are properly installed, and there is no need to reduce the capacity of the solar panels.

(Summary)
As shown in FIG. 1, a building 100 according to this embodiment includes a solar cell panel 1, a support portion 2 extending from a rooftop beam H above a roof R, a frame 3 suspended between the pair of support portions 2, a panel frame 4 suspended between the pair of frame beams 3 and supporting the solar cell panel 1, and a vibration control device 9 suspended between the pair of frame beams 3. The building 100 is a vibration-controlled building whose vibration is controlled by the vibration control device 9. The building 100 is also an environmentally friendly building equipped with a solar cell panel 1. In FIG. 1, the direction along the vertical direction is shown as direction G. In the following description, the downward direction in the vertical direction may be simply referred to as "down" or the like. Furthermore, the upward direction in the vertical direction may be simply referred to as "up" or the like.

In the building 100, the vibration control device 9 is disposed between a pair of panel frames 4 and below the solar panel 1.

In the building 100, vibration control performance is ensured when the solar panel 1 is properly installed. In the building 100, there is no need to reduce the capacity of the solar panel 1 to ensure vibration control performance.

(Detailed explanation)
As shown in FIG. 1, the building 100 includes a rooftop beam H, which is a part of the framework, a roof R supported by the rooftop beam H, a support section 2 supported by the rooftop beam H and extending from the rooftop beam H through the roof R to above the roof R, and a solar cell panel 1, a frame beam 3, a panel frame 4, and a vibration control device 9 arranged on the roof R. In the building 100, the solar cell panel 1 and the vibration control device 9 are supported by the rooftop beam H, the support section 2, the frame beam 3, and the panel frame 4, and the support is reinforced. Hereinafter, all or part of the rooftop beam H, the support section 2, the frame beam 3, and the panel frame 4 in the building 100 may be referred to as a support structure. Note that FIG. 1 is a perspective view of a state in which a part of the support structure is disassembled to explain the support structure of the solar cell panel 1 and the vibration control device 9 in the building 100.

A specific example of the building 100 is a multi-story house with a steel frame. The building 100 may have multiple rooms. The building 100 may be composed of a reinforced concrete foundation, a framework made up of framework members such as columns and beams, and a superstructure fixed to the foundation, which has panels forming the walls, floors, etc. The framework members and panels of the building 100 may be standardized in advance. In this case, the framework members and the like can be manufactured in advance in a factory and transported to the construction site, where the building 100 can be assembled.

The building 100 may have solar panels 1 installed from the time of construction, or may have solar panels 1 installed as an additional feature after construction.

The building 100 may have the vibration control device 9 installed together with the solar panel 1 from the time of construction, or the vibration control device 9 may be added after the solar panel 1 is installed.

The roof R is the upper surface of the building 100 and is supported by the roof beams H. In the building 100, the solar panel 1, the mounting beams 3, the panel frame 4, and the vibration control device 9 are installed on the roof R, and the weight of the solar panel 1, the mounting beams 3, the panel frame 4, and the vibration control device 9 is supported by the roof beams H via the support parts 2 described below.

The support portion 2 is a pillar or a column base whose lower portion is supported by the roof floor beam H, and may be column-shaped or frame-shaped. FIG. 1 shows the case where the support portion 2 is a column base. The support portion 2 is supported by the roof floor beam H and is integrated with the framework of the building 100. This allows the support portion 2 to be firmly supported by the building 100.

The solar cell panel 1 is a power generation device that generates electricity by receiving irradiation from the sun. The solar cell panel 1 may be a typical plate-shaped one. In this embodiment, the solar cell panel 1 is described below as being in the form of a rectangular plate. The solar cell panel 1 is fixed to the panel frame 4 while being placed on the panel frame 4, as described below.

The vibration control device 9 may be one in which a weight element and a vibration control mechanism including the weight element are housed in a housing. A vibration control device 9 having appropriate vibration control performance can be adopted in the building 100. In the building 100, for example, the solar cell panel 1 is not a weight element, so appropriate vibration control performance can be ensured regardless of the weight of the solar cell panel 1. In the following embodiment, the vibration control device 9 is described below by taking as an example a case in which the vibration control device 9 has a rectangular housing that is rectangular when viewed from above and has a low height along the vertical direction.

The vibration control device 9 is disposed below the solar cell panel 1, as described below. In this embodiment, the vibration control device 9 overlaps with the solar cell panel 1 when viewed from above the building 100. That is, the vibration control device 9 is disposed between the roof R and the solar cell panel 1. This allows the solar cell panel 1 to be installed in a small space, and the vibration control device 9 controls the vibration of the building 100. Details of the arrangement and installation state of the vibration control device 9 will be described below together with the explanation of the mounting beam 3 and the panel frame 4.

The frame beam 3 is a frame that supports the solar cell panel 1 and the vibration control device 9. The frame beam 3 is supported by the support part 2. As shown in FIG. 1, the frame beam 3 is fixed to the support parts 2, 2 by metal fittings or the like while being stretched across the pair of support parts 2, 2. In other words, the frame beam 3 is supported by the pair of support parts 2, 2. As a result, the frame beam 3 and the solar cell panel 1 and the vibration control device 9 installed on the frame beam 3 are firmly supported by the rooftop beam H, which serves as the framework of the building 100, improving the vibration control performance of the building 100, and in particular the solar cell panel 1 and the vibration control device 9.

The frame beam 3 supports the vibration control device 9 at its lower part. In other words, the vibration control device 9 is supported at the lower part of the frame beam 3. As a result, as described below, the vibration control device 9 is disposed below the solar cell panel 1, and the vibration control device 9 and the solar cell panel 1 can coexist in the building 100 without increasing the installation height of the solar cell panel 1. The manner in which the frame beam 3 supports the vibration control device 9 in this embodiment will be described later.

The frame beam 3 may be a so-called H-shaped steel as shown in Figs. 1 and 2. In the following, a case where the frame beam 3 is an H-shaped steel will be described as an example. In this embodiment, the frame beam 3 is supported by the support part 2 in a horizontal H-shaped manner as shown in Fig. 2. In the following, the upper plate-shaped part of the H-shaped frame beam 3 is referred to as the upper plate 31, the lower plate-shaped part is referred to as the lower plate 32, and the plate-shaped part spanning between the upper plate 31 and the lower plate 32 is referred to as the vertical plate 30. The lower plate 32 supports the vibration control device 9. This allows the vibration control device 9 to be supported at the lower part of the frame beam 3. The upper plate 31 supports the panel frame 4 as described later. This allows the vibration control device 9 to be located below the solar cell panel 1, and allows the vibration control device 9 and the solar cell panel 1 to coexist in the building 100 without increasing the installation height of the solar cell panel 1.

1 shows a case where an L-shaped metal fitting 39, which is a plate material bent into an L-shape, is used as a metal fitting for fixing the frame beam 3 to the support part 2. The L-shaped metal fitting 39 may have one of the surfaces of the plate part in the L-shape, the outer surface of the L-shape facing the upper surface of the support part 2. The other surface of the plate part in the L-shape may have the outer surface of the L-shape facing the end surface (small end surface) of the frame beam 3. Furthermore, each plate part of the L-shaped metal fitting 39 may be fixed to the upper surface part of the support part 2 and the end surface part of the frame beam 3, for example, by a bolt. In this way, by connecting the upper surface part of the support part 2 and the end surface part of the frame beam 3 using the L-shaped metal fitting 39, the frame beam 3 can be fixed to the support part 2 while maintaining the upper surface of the frame beam 3 at a low height in the vertical direction. This also makes it possible to support the vibration control device 9 at a low height in the vertical direction, as described later, and to realize the coexistence of the vibration control device 9 and the solar cell panel 1 in the building 100.

In this embodiment, the vibration damping device 9 is supported by a pair of frame beams 3, 3. That is, the vibration damping device 9 is placed on the frame beams 3, 3 so as to span between the frame beams 3, 3, and is fixed to the frame beams 3, 3. As described later, the pair of frame beams 3, 3 may support multiple vibration damping devices 9.

The frame beam 3 may have a connection plate 5 that supports the vibration-damping device 9. The connection plate 5 may be a rectangular plate material. In this embodiment, the connection plate 5 is fixed to the lower plate 32 located at the lower part of the frame beam 3. The vibration-damping device 9 can be placed on the upper surface of the pair of connection plates 5, 5. This allows support with appropriate strength to be achieved when the vibration-damping device 9 is supported at the lower part of the frame beam 3. The connection plate 5 may be fixed to the upper surface of the lower plate 32.

The connection plate 5 may be reinforced as necessary. As shown in FIG. 3, the connection plate 5 may have a reinforcing portion 51 extending from, for example, one plate surface (for example, the lower surface) of the plate portion 50. The reinforcing portion 51 may be arranged, for example, along the longitudinal direction of the plate portion 50. The reinforcing portion 51 may be, for example, a thin frame material fixed to the plate portion 50 with a bolt or the like. By reinforcing the connection plate 5 with the reinforcing portion 51, the support strength when the vibration control device 9 is supported at the lower part of the frame beam 3 can be increased. In addition, the thickness of the connection plate 5 can be reduced while maintaining strength, thereby lowering the height of the upper surface of the vibration control device 9. By lowering the height of the upper surface of the vibration control device 9, it is possible to easily arrange the vibration control device 9 below the solar panel 1.

Figure 3 shows a case in which the reinforcing portion 51 is a thin frame material, and a pair of reinforcing portions 51, 51 are fixed with bolts or the like at positions close to both long sides of the plate portion 50 along the longitudinal direction of the plate portion 50.

As shown in FIG. 1, the panel frame 4 is a frame material that supports the solar cell panel 1. The panel frame 4 is fixed to the pair of frame beams 3, 3 while being suspended between them. The panel frame 4 intersects with the frame beam 3. As shown in FIGS. 1 and 4, the panel frame 4 is perpendicular to the frame beam 3 in this embodiment. The panel frame 4 may be supported on the upper part of the frame beam 3. In this embodiment, the panel frame 4 is fixed to the frame beam 3 while being placed on the upper surface of the upper plate 31. Note that FIG. 4 is a top view of the lower part of the solar cell panel 1 in the building 100 as seen from above. For ease of explanation, the outline of the solar cell panel 1 is shown by a dashed line in FIG. 4.

In this embodiment, as described above, the vibration control device 9 is supported on the lower part of the frame beam 3, and the panel frame 4 supporting the solar cell panel 1 is supported on the upper part of the frame beam 3. Therefore, the vibration control device 9 is supported on the frame beam 3 at a position lower than the panel frame 4 by an amount corresponding to the height of the frame beam 3. This allows the height of the upper surface of the vibration control device 9 to be lowered. By lowering the height of the upper surface of the vibration control device 9, it is possible to easily arrange the vibration control device 9 below the solar cell panel 1. In other words, the vibration control device 9 is arranged below the solar cell panel 1, and the coexistence of the vibration control device 9 and the solar cell panel 1 in the building 100 is realized without increasing the installation height of the solar cell panel 1. In this embodiment, the panel frame 4 is fixed to the upper surface of the frame beam 3.

As described above, the solar cell panel 1 is placed on the panel frame 4. In this embodiment, the solar cell panel 1 is placed on the panel frame 4 so as to span the pair of panel frames 4, 4. As shown in FIG. 5, multiple solar cell panels 1 may be arranged adjacent to each other on the pair of panel frames 4, 4.

As shown in Figures 1 and 4, the pair of panel frames 4, 4 may be arranged along both sides of the vibration control device 9. In other words, the vibration control device 9 may be arranged between the pair of panel frames 4, 4. By arranging the vibration control device 9 between the pair of panel frames 4, 4 in this manner, the installation space can be used efficiently. In this state, the vibration control device 9 is arranged to overlap the solar cell panel 1 when viewed from above. This allows the solar cell panel 1 and the vibration control device 9 to be installed in the same position when viewed from above, allowing the installation space to be used efficiently.

As shown in Figures 1 and 4, when a pair of panel frames 4, 4 are arranged along both sides of the vibration control device 9, the solar panel 1 and the vibration control device 9 are supported by a sturdy lattice-like support structure surrounded by a pair of mounting beams 3, 3 and a pair of panel frames 4, 4 suspended across the pair of mounting beams 3, 3. This improves the vibration control performance of the building 100, and in particular the solar panel 1 and the vibration control device 9.

As shown in FIG. 2, the height of the upper surface of the panel frame 4 is set to be the same as the height of the upper surface of the vibration damping device 9 or higher than the height of the upper surface of the vibration damping device 9. This makes it possible to avoid interference between the solar cell panel 1 and the vibration damping device 9. In this embodiment, the vibration damping device 9 is supported on the lower part of the mounting beam 3, and the panel frame 4 supporting the solar cell panel 1 is supported on the upper part of the mounting beam 3. Therefore, it is easy to realize an arrangement in which the height of the upper surface of the panel frame 4 is set to be the same as the height of the upper surface of the vibration damping device 9 or higher than the height of the upper surface of the vibration damping device 9.

Note that while FIG. 2 illustrates an example in which the solar cell panel 1 is installed horizontally on the panel frame 4, the solar cell panel 1 may also be installed at an angle. In this case, for example, a spacer may be placed between the panel frame 4 and the solar cell panel 1 to provide the angle.

The configuration of the building 100 is as described above. Below, a specific example in which the building 100 has multiple solar panels 1 and vibration control devices 9 will be described. Figure 5 shows a top view of the building 100 in the case where it has multiple solar panels 1 and vibration control devices 9.

In the building 100 shown in FIG. 5, a solar panel 1 is installed on one surface of the roof R. The vibration control device 9 is installed in a partial area on the roof R.

On the roof R of the building 100, multiple support parts 2 are exposed (protruding from the surface of the roof R) that extend above the roof R from the rooftop beams H (see Figures 1 and 2). The support parts 2 are arranged near the outer periphery of the roof R of the building 100 or in the center of the roof R. In Figure 5, the panel frame that supports only the solar cell panel 1 via the panel frame 4 and is supported by the support parts 2 is shown as the panel mounting beam 8. The panel mounting beam 8 does not support the vibration control device 9. The panel mounting beam 8 is supported by a pair of support parts 2, 2, like the mounting beam 3.

Figure 5 shows a case where one platform beam 3 is suspended between a pair of supports 2, 2, and multiple vibration control devices 9 (two in Figure 5) are placed on the pair of platform beams 3, 3. As shown in Figure 5, the platform beam 3 may be supported by a structure other than the supports 2, 2 as needed. In Figure 5, an example of a structure that supports the platform beam 3 as needed is shown as an auxiliary support support 83. The auxiliary support support 83 is placed on or fixed to the roof R. The auxiliary support support 83 does not need to be supported by the rooftop beam H. The auxiliary support support 83 may be placed between the supports 2, 2 on the platform beam 3. The auxiliary support support 83 may be installed as needed, and is not essential.

In FIG. 5, the panel frame 4 is supported by the mounting beam 3 or the panel mounting beam 8. As shown in FIG. 5, the panel frame 4 or a part of the panel frame 4 supporting the solar cell panel 1 at the location where the vibration control device 9 is arranged below is supported by the mounting beam 3. Also, the panel frame 4 or a part of the panel frame 4 supporting the solar cell panel 1 at the location where the vibration control device 9 is not arranged below may be supported by the panel mounting beam 8. The panel frame 4 may be hung across the mounting beam 3 and the panel mounting beam 8. In the building 100, the solar cell panels 1 adjacent to each other in the extension direction of the panel frame 4 are supported integrally by the same panel frame 4 regardless of whether the vibration control device 9 is installed in the area or not, so that each solar cell panel 1 is firmly supported integrally. This improves the vibration control performance of the building 100, especially the solar cell panel 1.

A plurality of solar cell panels 1 may be placed adjacent to each other on a pair of panel frames 4, 4. In FIG. 5, four solar cell panels 1 are placed on a pair of panel frames 4, 4.

The building 100 shown in FIG. 5 is an example of a building in which solar panels 1 were installed from the time of construction, but vibration control devices 9 were not installed at the time of construction. In other words, the building 100 shown in FIG. 5 is a building in which vibration control devices 9 were added and installed later after the solar panels 1 were installed.

Adding a vibration control device 9 to a building 100 that has only solar panels 1 installed and no vibration control device 9 installed can be done, for example, as follows.

First, the panel frames 4, 4 that overlap the area where the vibration control device 9 is to be installed in the top view of the building 100 and the solar cell panels 1 on these panel frames 4, 4 are removed. Furthermore, the panel mounting beams 8 in the area where the vibration control device 9 is to be installed are replaced (exchanged) with the mounting beams 3. At this time, the panel mounting beams 8 are replaced with the mounting beams 3 so that the mounting beams 3 are supported by at least a pair of support parts 2, 2. Then, the vibration control device 9 is fixed to the mounting beams 3. Furthermore, the removed panel frame 4 is fixed. The panel frame 4 can be used as it is without modification. At this time, the panel frame 4 may be hung across the mounting beams 3 and the panel mounting beams 8. The height of the upper surface of the mounting beams 3 is set to be the same as the height of the upper surface of the panel mounting beams 8. Then, the removed solar cell panels 1 are reattached to the panel frames 4, 4.

In addition, some of the solar cell panels 1 may be supported via brackets (not shown) fixed to the support section 2 instead of being supported by the panel frames 4, 4. In this case, the panel mounting beams 8 in the area where the solar cell panels 1 are supported by the brackets are replaced with brackets. The solar cell panels 1 are then fixed to these brackets, and the solar cell panels 1 may be supported directly above the support section 2 via these brackets.

Since the addition of vibration control devices 9 to a building 100 in which only solar cell panels 1 are installed and no vibration control devices 9 are installed can be performed as described above, the existing solar cell panels 1 and panel frames 4 are not wasted, and a reduction in the power generation capacity of the building 100 can be avoided. In other words, the support structure for the solar cell panels 1 and vibration control devices 9 in the building 100 according to this embodiment can reduce the waste of the existing solar cell panels 1 and panel frames 4, and avoid a reduction in the power generation capacity of the building 100. In other words, there is no need to reduce the capacity of the solar cell panels 1.

In this way, it is possible to provide a building in which vibration control performance is ensured when the solar panels are properly installed, and there is no need to reduce the capacity of the solar panels.

The configurations disclosed in the above embodiment (including other embodiments, the same applies below) can be applied in combination with configurations disclosed in other embodiments, provided no contradictions arise. Furthermore, the embodiments disclosed in this specification are merely examples, and the present invention is not limited to these embodiments. Appropriate modifications can be made without departing from the scope of the present invention.

This invention can be applied to buildings.
