  As a building ventilation system, air supply towers for supplying outside air to the lower area of the indoor space and exhaust towers for discharging air from the upper area of the indoor space are installed at multiple locations around the building, respectively. With this configuration, the indoor space can be ventilated more efficiently, and a ventilation system can be easily installed in an existing building.

  However, in such a case, there is a problem that it is not always easy to secure a dedicated space for installing a plurality of air supply towers and exhaust towers around the building.

  In particular, when seismic reinforcement structures are installed at multiple locations around a building, it is quite difficult to secure dedicated spaces for installing multiple air supply towers and exhaust towers. There is a problem that it becomes difficult.

  The present invention has been made in view of such circumstances, and in a ventilation system for ventilating an indoor space of a building, it is possible to easily secure the installation space and efficiently ventilate the indoor space.

It may be an installed configuration. In addition, each of these “air supply tower” and each “exhaust tower” may be configured separately from each seismic reinforcement structure, or may be configured as a part of each earthquake resistance structure. It may be what was done.

  As shown in the above configuration, the building ventilation system according to the present invention includes an air supply tower for supplying outside air to a lower region of the indoor space at a plurality of locations around the building, and an upper region of the indoor space. Each of the air supply tower and each exhaust tower is installed in each of the seismic reinforcement structures installed at multiple locations around the building. Since it is installed in the space, the following effects can be obtained.

  That is, the indoor space can be efficiently ventilated by adopting a configuration in which the air supply tower and the exhaust tower are installed at a plurality of locations. At that time, by providing a configuration in which the air supply tower and the exhaust tower are installed around the building, the ventilation system can be easily installed in the existing building.

  Moreover, these air supply towers and exhaust towers are installed in the installation spaces of the seismic reinforcement structures installed at multiple locations around the building, so they are dedicated spaces for installing the building ventilation system. Can be eliminated.

  In other words, since the supply tower can be cooled by the latent heat of vaporization from the sprinkler from the watering device, the air in the supply tower can be cooled accordingly, thereby generating the downdraft in the supply tower. Can be promoted. And thereby, the function as an air supply tower for supplying outside air to the lower region of the indoor space of the building can be enhanced.

  In the above configuration, each of the air supply towers and each of the exhaust towers is provided with a steel pipe extending in the vertical direction and a connecting member that connects the steel pipe and the main structure of the building as each seismic reinforcement structure. If it is made of a steel pipe having an earthquake-resistant reinforcing structure, the following effects can be obtained.

In addition, since it is not necessary to consider that the air supply tower and the exhaust tower are installed separately from the seismic reinforcement structure as a structure of the seismic reinforcement structure, it is possible to increase the degree of freedom of the construction of the seismic reinforcement structure. it can.

  In the above configuration, if each of the air supply towers and each of the exhaust towers is configured as a composite tower arranged in series in the vertical direction with the air supply tower facing down, the installation efficiency of the air supply tower and the exhaust tower can be increased. And thereby, the ventilation efficiency of indoor space can further be improved, maintaining the structure of an earthquake-proof reinforcement structure constant.

  Next, a specific configuration of the seismic reinforcement structure 50 will be described.

  3 is a detailed view taken in the direction of the arrow III in FIG. 1, and FIG. 4 is a sectional view taken along line IV-IV in FIG.

  As shown in these drawings, in the building 100, a main structure 120 of the building 100 is installed in the vicinity of a south side wall 114 (indicated by a two-dot chain line in FIG. 4) in the indoor space 102.

  The main body structure 120 is formed of a steel frame including a columnar member 122 extending in the vertical direction and beam members 124 whose ends are joined to the columnar member 122 at a plurality of positions in the vertical direction.

  At that time, the columnar member 122 is made of an H-section steel having a relatively large cross-sectional shape, and is arranged so that the web thereof is perpendicular to the south side wall 114, and is fixed to the ground at the lower end portion thereof. Has been. On the other hand, the beam member 124 is made of an H-section steel having a relatively small cross-sectional shape, and is arranged so that the web thereof is parallel to the south side wall 114, with the gusset plate 126 interposed at the end thereof. It is joined to the columnar member 122. In the present embodiment, the south side wall 114 is arranged along the flange of the columnar member 122.

  The columnar member 52 that constitutes a part of the seismic reinforcement structure 50 is disposed at a position that is a predetermined distance away from the columnar member 122 of the main structure 120 with respect to the south side wall 114 in a direction perpendicular to the surface. It is fixed to. The columnar member 52 is made of an H-section steel having a relatively large cross-sectional shape, and is arranged so that the web thereof is perpendicular to the south side wall 114.

  The connecting member 54 constituting a part of the seismic reinforcing structure 50 is arranged so as to connect the columnar member 52 of the seismic reinforcing structure 50 and the columnar member 122 of the main structure 120. The connecting member 54 is made of an H-section steel having a relatively small cross-sectional shape, and the web is flush with the south side wall 114 and is flush with the respective H-section steel webs constituting the columnar members 52 and 122. It is arranged so as to extend in the vertical direction. The connecting member 54 is joined to the flange of the columnar member 52 and the flange of the columnar member 122 at both ends thereof.

  The connecting member 56 that constitutes a part of the seismic reinforcing structure 50 is composed of two pairs of upper and lower brace members arranged in symmetrical positions on both sides of the connecting member 54, and the columnar member 52 of the seismic reinforcing structure 50. And the beam member 124 of the main structure 120 are connected to each other. At that time, a turnbuckle 58 for adjusting the tension is interposed at the end of each connecting member 56 on the columnar member 52 side.

  Each of the connecting members 56 is connected to the columnar member 52 by bolting a gusset plate 62 attached to the columnar member 52. The connection members 56 are connected to the beam member 124 by bolting the tab plate 128 attached to the beam member 124.

Each of the pair of exhaust towers 20 is installed so as to be located in each of the pair of idle spaces.

  The seismic reinforcement structure 50 installed along the north side wall 112 has the same configuration as that of the seismic reinforcement structure 50 installed along the south side wall 114, and each of the pair of idle spaces has the same structure. The same applies to the point that each of the pair of supply towers 10 is installed so as to be positioned.

  Next, the effect of this embodiment is demonstrated.

  The building ventilation system according to the present embodiment supplies air from a supply tower 10 for supplying outside air to a lower region of the indoor space 102 at a plurality of locations around the building 100 and an upper region of the indoor space 102. Since the exhaust tower 20 for discharging is installed, the indoor space 102 can be efficiently ventilated, and a ventilation system can be installed in an existing building. Easy to do.

  At this time, each of the air supply tower 10 and each exhaust tower 20 is installed in the installation space of each of the earthquake-proof reinforcement structures 50 installed at a plurality of locations around the building 100. It is possible to eliminate the need to secure a dedicated space for installation.

  As described above, according to the present embodiment, in the ventilation system that ventilates the indoor space 102 of the building 100, the installation space can be easily secured, and the indoor space 102 can be efficiently ventilated.

  At that time, in the building ventilation system according to the present embodiment, the air supply tower 10 is provided with the watering device 30 for sprinkling water in the outside air passage 14. When the water droplet naturally falls, a descending airflow can be formed in the outside air passage 14. As a result, the chimney effect can be enhanced even on the air supply side of the indoor space 102, so that the ventilation efficiency of the indoor space 102 can be further increased.

  Moreover, when the water droplets sprinkled from the water sprinkler 30 naturally fall, the air in the outside air passage 14 can be cooled by the evaporative cooling action. And since the air cooled in this way flows into the lower area | region of the indoor space 102, the cooling effect of the indoor space 102 can be heightened by this.

  Further, the watering device 30 has the water supply control unit 34 disposed at a position higher than the roof 116 of the building 100, and the side wall surface exposed from the peripheral wall of the air supply tower 10 toward the south side is a solar cell panel. Since it is comprised as 34a, it becomes possible to generate | occur | produce the drive electric power for water supply control with sunlight.

  Further, in the present embodiment, waste heat generated in the building 100 (specifically, exhaust heat from the outdoor unit 40 of the air conditioner) is transferred to the exhaust air tower 24 via the internal air passage extension 24E. Since the waste heat supply port 28 for supply is formed, the heat rising from the waste heat supply port 28 in the inside air passage extension 24E can promote the formation of the updraft in the inside air passage 24. The ventilation efficiency can be further increased by that much.

  In the above embodiment, the seismic reinforcement structures 50 are installed at six locations around the building 100, and the supply tower 10 and the exhaust tower 20 are installed at three locations, respectively. It is also possible to adopt a configuration in which the reinforcing structures 50 are installed at 5 or less locations or 7 or more locations. In addition, it is not always necessary to have a configuration in which the air supply tower 10 and the exhaust tower 20 are installed in all the installation locations of the earthquake-proof reinforcement structure 50.

  In the above embodiment, the case where the ventilation system is applied to the single large indoor space 102 has been described. However, even in the case where the ventilation system is partitioned into a plurality of small indoor spaces, each indoor space is divided into the ventilation system. If it is set as an application target, it is possible to obtain the same operational effects as in the above embodiment.

  Next, a modification of the above embodiment will be described.

  First, a first modification of the above embodiment will be described.

  FIG. 5 is a view similar to FIG. 4 showing a part of a building ventilation system according to this modification.

  That is, the seismic reinforcement structure 150 of the present modification is a deformed H-section steel in which the columnar member 152 extending in the vertical direction has a cross-sectional shape that further increases the cross-sectional shape of the H-section steel constituting the columnar member 52 of the above embodiment. It is configured. The columnar member 152 has a web 152W extending long in a direction perpendicular to the south side wall 114 of the building 100, and one flange 152F1 is bolted to the flange of the columnar member 122 in the main structure 130 of the building 100. Directly connected by tightening. As a result, the columnar member 152 also has a function as the connecting member 54 of the above-described embodiment.

  The other flange 152F2 in the columnar member 52 is formed wider than the one flange 152F1, and a pair of left and right gusset plates 162 are vertically spaced between the flange 152F1 and the web 152W. Attached to multiple locations.

  In the seismic strengthening structure 150 of this modification, the connecting member 156 corresponding to the connecting member 56 in the seismic strengthening structure 50 of the above embodiment is made of angle steel, not a brace material. The connecting member 156 connects the columnar member 152 of the seismic reinforcement structure 150 and the beam member 134 of the main structure 130 on the left and right sides of the columnar member 52 in the same positional relationship as the connecting member 56 of the above embodiment. Yes. This connection is performed by bolting both ends of the columnar member 152 to the gusset plate 162 and the tab plate 138 attached to the beam member 134, respectively.

  In this modification, the beam member 134 constituting the main structure 130 of the building 100 is formed with a larger cross-sectional shape than the beam member 124 of the above-described embodiment, and the shape and arrangement of the tab plate 138 are also different. This is slightly different from the above embodiment. In this modification, the south side wall 114 is arranged along the beam member 134.

  The seismic reinforcement structure 150 of this modification also occupies a substantially isosceles triangular installation space in plan view, like the seismic reinforcement structure 50 of the above-described embodiment, and between the connection member 54 and the connection members 56 on both sides thereof. A pair of substantially right-angled triangular idle spaces is formed. Each of the pair of exhaust towers 20 is installed so as to be located in each of the pair of idle spaces.

  The seismic reinforcement structure 150 installed along the north side wall 112 has the same configuration as that of the seismic reinforcement structure 150 installed along the south side wall 114, and each of the pair of idle spaces has the same structure. The same applies to the point where each of the pair of supply towers 10 is installed so as to be positioned.

  Even in the case of adopting the configuration of the present modification, it is possible to obtain the same operational effects as in the case of the above embodiment.

  In addition, the configuration of the seismic reinforcement structure 150 can be simplified by adopting the configuration of the present modification.

  Next, a second modification of the above embodiment will be described.

  FIG. 6 is a view similar to FIG. 4 showing a part of a building ventilation system according to this modification.

  As shown in the figure, the basic configuration of the building ventilation system according to the present modification is the same as that of the above embodiment, but the structure of the seismic reinforcement structure 250 is the same as that of the above embodiment. It differs from the above embodiment in that a single exhaust tower 20 is installed in the installation space.

  In this modification, the main structure 130 of the building 100 and the arrangement of the south side walls 114 are the same as those in the first modification.

  The seismic reinforcement structure 250 according to this modification includes a columnar frame 252 and connecting members 254 that connect the columnar frame 252 and the main structure 130 at a plurality of locations in the vertical direction.

  The columnar frame 252 has four angle steels 252A extending in the vertical direction so as to be positioned at each rectangular corner portion in plan view, and circumscribes these four angle steels 252A at a plurality of vertical positions. It is composed of four angle steels 252B assembled in a well beam. At that time, the four angle steels 252B assembled in the cross beam are fixed to each other by bolting, and are fixed to each of the four angle steels 252A extending in the vertical direction by bolting.

  The connecting member 254 is composed of four angle steels arranged in a substantially W shape in plan view. At that time, of these four angle steels, the two angle irons on the inner side are the angle plate 252B of the columnar frame 252 and the tab plate 236 attached to the flange of the columnar member 122 of the main structure 130 at both ends. The two outer angle irons are connected to each other by an angle steel 252B of the columnar frame 252 and a tab plate 238 attached to the beam member 134 of the main structure 130. Each is connected by bolting.

  In this modification, the exhaust tower 20 is installed in the space inside the four angle irons 252B assembled in the wells of the columnar frame 252 of the seismic reinforcement structure 250. That is, also in this modification, the exhaust tower 20 is installed in the installation space of the earthquake-proof reinforcement structure 250. However, in the exhaust tower 20, an internal air flow inlet (not shown) for allowing the air in the indoor space 102 to flow into the internal air passage 24 communicates with the indoor space 102 at a position avoiding the columnar member 122 of the main structure 130. It is formed to do.

  The seismic reinforcement structure 250 installed along the north side wall 112 has the same configuration as that of the seismic reinforcement structure 250 installed along the south side wall 114, and the four seismic reinforcement structures 250 installed in the well girder. The same applies to the point that the single air supply tower 10 is installed in the space inside the angle iron 252B.

  Even in the case of adopting the configuration of the present modification, it is possible to obtain the same operational effects as in the case of the above embodiment.

  In addition, by adopting the configuration of this modification, the seismic reinforcement structure 250 can be constructed by a combination of angle steels.

  Next, a third modification of the above embodiment will be described.

  FIG. 7 is a view similar to FIG. 4 showing a part of a building ventilation system according to this modification.

  As shown in the figure, the basic configuration of the building ventilation system according to this modification is the same as that of the above embodiment, but the structure of the seismic reinforcement structure 350 is the same as that of the above embodiment. It is also different from the above embodiment in that a single exhaust tower 320 is installed in the installation space.

  In this modification, the main structure 130 of the building 100 and the arrangement of the south side walls 114 are the same as those in the first modification.

  The seismic reinforcement structure 350 according to the present modification includes a steel pipe 352 extending in the vertical direction, and a connecting member 354 that connects the steel pipe 352 and the columnar member 122 of the main structure 130 of the building 100 at a plurality of locations in the vertical direction. Yes. At that time, the connecting member 354 extends in a direction perpendicular to the south side wall 114 so as to be flush with the web of the columnar member 122 of the main structure 120.

  And the exhaust pipe 320 of this modification is comprised by the steel pipe 352 of this earthquake-proof reinforcement structure 350. FIG. At this time, the exhaust tower 320 is formed to be thicker than the exhaust tower 20 of the above-described embodiment in order to ensure sufficient rigidity as a component of the seismic reinforcement structure 350. In the exhaust tower 320, an internal air flow inlet (not shown) for allowing the air in the indoor space 102 to flow into the internal air passage 324 communicates with the indoor space 102 at a position avoiding the columnar member 122 of the main structure 130. It is formed to do.

  The seismic reinforcement structure 350 installed along the north side wall 112 has the same configuration as that of the seismic reinforcement structure 350 installed along the south side wall 114, and the steel pipe 352 as a component is the above-described component. The same applies to the point that a thicker air supply tower is configured than the air supply tower 10 of the embodiment.

  Even in the case of adopting the configuration of the present modification, it is possible to obtain the same operational effects as in the case of the above embodiment.

  In addition, by adopting the configuration of this modification, each air supply tower and each exhaust tower 320 itself constitutes a part of each seismic reinforcement structure 350, so that the air supply tower can be formed with a minimum space. The exhaust tower 320 and the seismic reinforcement structure 350 can be installed. Further, since it is not necessary to consider that the air supply tower and the exhaust tower 320 are installed separately from the earthquake resistant reinforcement structure 350 as the structure of the earthquake resistant reinforcement structure 350, the degree of freedom in the structure of the earthquake resistant reinforcement structure 350 is eliminated. Can be increased.

  Next, the 4th modification of the said embodiment is demonstrated.
