  The present invention relates to a roof structure in a large container such as a building or a container, and in particular, a ventilation port is provided in a roof of a transportable building or the like, thereby enabling efficient natural ventilation while preventing intrusion of rainwater. It relates to the roof structure.

For the transportation of various cargoes, containers that can prevent cargo damage due to wind and rain and simplify the packaging of cargoes are actively used. The container is a large cuboid container having a solid structure surrounded by a strong wall surface, and a fastener called a corner casting is attached to a corner so that the container can be stacked and loaded. During transportation by a vehicle, the container is usually loaded on a trailer (container chassis) pulled by a tractor, and is fixed to the trailer by a tightening tool called a twist lock.
An example of such a trailer is shown in FIG. The trailer frame FR includes two main beams MB extending in parallel in the front-rear direction over the entire length, and a plurality of cross members CM connecting between the main beams MB. A bolster BS extending in the lateral direction is provided in the vicinity of the stepped portion of the frame FR and the rear end portion of the main beam MB, and twist locks TL shown in an enlarged view are provided at both ends thereof. When loading a container, the head of the twist lock TL is inserted into a rectangular through hole in corner casting on the bottom surface of the container, and the handle is fixed to fix the container.

  Since the transport container is a large container with a robust structure, it may be modified for use in a building such as a warehouse. For example, with the development of computer networks, the number of data centers that manage large computers in a centralized manner is increasing rapidly. Some data centers include container-type data centers that are constructed by modifying containers (module type). Data center). Container-type data centers are highly air-tight, easy to protect computers by preventing intrusion of dust, and are based on containers for transportation. It has the advantage that expansion by combination is easy.

As an example of a building using containers, a data center disclosed in Japanese Patent Application Laid-Open No. 2013-19617 related to the prior application of the present applicant will be described with reference to FIG.
The data center shown in FIG. 11 has a box-like structure, which is a hexahedron, as a whole, like a general container, and has a rectangular shape in plan view. Columnar members PL extending in the vertical direction are disposed at the four corners of the rectangle, and fasteners (corner castings) CC are fixed to the upper and lower portions of the columnar member PL. Inside the data center, a plurality of racks LC containing computers such as servers are accommodated (in the upper diagram of FIG. 11, the side walls of the box structure are shown).

By the way, in a data center having a large number of computers, it is necessary to ventilate or air-condition the room so as to avoid a thermal failure caused by the heat generated by the computer. In the data center of FIG. In order to suppress the use as much as possible, an outside air cooling type cooling device is employed. This cooling device radiates indoor heat to the outside air by utilizing the phase change of the refrigerant sealed in two heat exchangers.
As shown in the enlarged cross-sectional view, an intermediate ceiling plate MC extending to the upper side of the rack LC is provided below the roof of the data center, an indoor heat exchanger IE is provided below, and an outdoor heat exchanger is provided above. Each OE is installed. When indoor air whose temperature has risen due to heat generated by the computer is passed through the indoor heat exchanger IE, the refrigerant in the indoor heat exchanger IE is boiled and evaporated and transferred to the outdoor heat exchanger OE. In the outdoor heat exchanger IE, the refrigerant is condensed by heat exchange with the outside air sucked by the fan OF, and is returned to the indoor heat exchanger IE by gravity. The air in the computer room CR circulates as indicated by the white arrow by the indoor fan IF, and cools itself while dissipating heat to the enclosed refrigerant when passing through the indoor heat exchanger IE.

JP 2013-19617 A

  Taking advantage of the fact that buildings based on containers for transportation can be easily transferred by vehicles or combined with multiple objects, it has recently attracted attention as a building for various purposes, not limited to data centers. Has been. As one of such things, it is considered that a container is remodeled to be a portable showroom that is used for display and advertisement of products at exhibitions or event venues.

When used as a showroom, it is necessary to attract the eyes of a large number of visitors. Therefore, although the design is particularly important, the container has a very hard impression because all corners are perpendicular. From the viewpoint of the design of the showroom, it is often desirable to use a curve in the appearance part such as a corner to give a soft impression. Moreover, it is desirable to use a transparent material such as polycarbonate or glass for the surrounding wall surface so that the products displayed in the showroom can be seen from the outside.
When a large number of visitors enter the showroom, the indoor air environment deteriorates due to the accumulation of carbon dioxide and temperature rise due to body temperature. Air conditioning needs to be considered. In showrooms that use transparent materials for the surrounding walls, temperature rise due to sunlight must also be considered.

Although the data center shown in FIG. 11 is a structure in which a container is modified, it has a rectangular parallelepiped box-type structure in which vertical columnar members are arranged at four corners, and has a surface that is too hard for a showroom design. In order to prevent temperature rise in the room, an outside air cooling type cooling device that uses less power is provided, but this cooling device is not only complicated and expensive, but the room is basically sealed. Therefore, it is not possible to improve the indoor air environment by introducing fresh outside air.
The present invention adopts a structure that enables efficient natural ventilation on the roof of a building when the shape of the container is changed to a building such as a showroom, and without using power such as electric power. The task is to preserve the air environment inside the room.

In view of the above-described problems, the present invention provides a roof structure of a building, in which plate material arrangement portions in which a plurality of plate materials extending in the longitudinal direction of the building are arranged in a stepwise manner are arranged above and below at intervals. A structure is provided on the roof, and natural air is ventilated from the roof of the building while preventing rainwater from entering. That is, the present invention
“A structure placed on the roof of a building,
A plurality of plate members that extend in the longitudinal direction of the building are arranged symmetrically with respect to the center line of the cross section of the building.
In the plate material arrangement portion, adjacent plate materials are arranged in a step so that the lateral ends thereof overlap in a plan view and there is a gap therebetween,
In the upper plate material arrangement portion, the plate material at the center of the cross section of the building is arranged at the highest position, and the plate material on the outer side is at a lower position, and the end of the plate material at the center of the cross section is bent downward. Part is formed, and the other plate material is formed with a downward bent portion at the outer end portion and an upward bent portion at the central end portion,
In the lower plate material arrangement portion, the plate material in the center of the cross section of the building is arranged at the lowest position, and the plate material on the outer side becomes higher, and the end of the plate material in the center of the cross section is bent upward. The other plate material has an upward bent portion at the outer end portion and a downward bent portion at the central end portion. ''
The structure is characterized by this.

  As described in claim 2, it is preferable that the plate member in the upper plate member arrangement portion and the plate member in the lower plate member arrangement portion are coupled by a connecting member having a rectangular frame structure. In this case, when the beam member extending in the longitudinal direction is installed on the upper part of the building, the connecting member can be attached to the beam member as described in claim 3.

  As described in claim 4, it is preferable that in the lower plate material arrangement portion, the plate material at the center of the cross section of the building is extended to the end in the longitudinal direction of the building and connected to the drainage device.

  As described in claim 5, a support member to which equipment of a building can be attached can be disposed between the upper plate member arrangement portion and the lower plate member arrangement portion.

  According to a sixth aspect of the present invention, it is preferable to provide air introduction holes on both sides of the lower part of the cross section of the building having the structure of the present invention.

  In addition, as described in claim 7, in a building having the structure of the present invention, a through-engagement hole that engages with a fastener installed in a vehicle is formed at the bottom edge of the building. It is preferable that the tool is fixed and transportable by the vehicle. In this case, as described in claim 8, the fastener can be provided with a screw block in which through screw holes are formed that open to the upper surface side and the lower surface side.

The structure of the present invention is installed on the roof of a building such as a showroom in which a container for transportation is modified, and is a plate material arrangement portion in which a plurality of plate materials extending in the longitudinal direction of the building are arranged in a stepwise combination. Are arranged above and below at intervals. In the upper plate arrangement part located at the top of the building, the plate at the center of the cross section of the building is placed at the highest position, so that the plate on the outer side is at a lower position, and the adjacent plate is The lateral ends overlap in a plan view, and a gap exists between them.
If the temperature of the room air rises due to the body temperature of the visitors to the building room or the incidence of sunlight, etc., the specific weight of the air decreases and natural convection occurs, and the hot air is at the top of the building. It flows toward the upper plate material arrangement part. And it passes through the gap | interval of the board | plate material which adjoins an upper board | plate material arrangement | sequence part, flows further upwards, and is discharged | emitted outside the building. That is, since the structure of the present invention is placed on the roof of a building and serves as an exhaust port for ventilation, the rising airflow does not stay or bend, and efficient natural ventilation is performed.

On the other hand, rainwater falls on the upper plate array part located at the uppermost part of the building, which may enter the building through the gap between the plate members. The lateral end portions overlap in plan view, and a downward bent portion is formed at the outer end portion, and an upward bent portion is formed at the central end portion. For this reason, the rainwater which is going to intrude is blocked by the upward bent portion, and basically, intrusion prevention is performed here (see FIG. 8 and the like described later).
Further, a lower plate material arrangement portion is placed below the upper plate material arrangement portion. The lower plate arrangement part has a shape (axisymmetric about the horizontal line) that is a mirror image of the upper plate arrangement part in the cross section of the building, and the plate in the center of the cross section is located at the lowest position. An upward bent portion is formed at the outer end. Even if rainwater enters the lower side of the upper plate array, the rainwater will eventually fall and be stored on the central plate placed at the lowest position, and enter the indoor side of the building. Is prevented. The rain water falling on the central plate material can be discharged to the outside of the building by means such as appropriately connecting a drain pipe. However, as in the invention of claim 4, the central plate material is disposed in the longitudinal direction of the building. When it is connected to a drainage device here, drainage can be achieved with a simple configuration without providing a pipe or the like in the room of the building.

The invention of claim 2 is to connect the plate material of the upper plate material arrangement portion and the plate material of the lower plate material arrangement portion using a connecting member having a rectangular frame structure. If it carries out like this, an upper and lower board | plate material arrangement | sequence part will be integrated, and it can attach to the roof of a building as a unit combined previously. Note that it is not always necessary to connect all the plate members in advance with the connecting member, and a part of the plate members may be separated and later assembled to the roof.
Here, in a building such as a showroom based on a container, it is convenient to install a beam material extending in the longitudinal direction on the top of the building to support the roof without placing a pillar supporting the roof in the room. . In a building having such a beam material, the roof structure can be attached to the building by fixing the connecting member to the beam material as in the invention of claim 3.

  According to the invention of claim 5, a support member is disposed between an upper plate material arrangement portion and a lower plate material arrangement portion, and a building equipment such as a lighting fixture is attached to the support member. According to the above, it is possible to effectively use the space of the roof portion.

  According to a sixth aspect of the present invention, in the building provided with the structure of the present invention, air introduction holes are provided on both sides of the lower portion of the cross section. Buildings are usually ventilated by natural circulation with air flowing in through gaps such as windows and doors. However, if an air introduction hole is provided in the lower part of the building, natural convection is promoted and more efficient. Ventilation is possible.

The invention of claim 7 is a building that can be transported by a vehicle such as a trailer, that is, a building in which a fastener having a through-engagement hole that engages with a fastener installed in the vehicle is fixed to the bottom. The roof structure of the present invention is attached. Although such a building is moved and installed in various event venues or the like, it may be difficult to secure a sufficient power source or the like depending on the location.
Since the building including the structure of the present invention performs ventilation by natural circulation, a fan driven by electric power or the like is not required. Therefore, the structure of the present invention is suitable for a building that can be transported by a vehicle. Further, as in the invention of claim 8, when a screw block having a through screw hole opened on the upper surface side and the lower surface side is provided in the fastener, a building is made using the through screw hole. The crane can be lifted by a crane, or a building can be stacked using a columnar body.

Next, the ventilation flow of the structure 1 and the prevention of rainwater intrusion will be described with reference to FIG.
When the temperature of the indoor air rises due to the influence of visitors and sunlight in the building ST room, the warmed air flows upward as indicated by the solid line arrows in FIG. It passes between the plate material arrangement portion 2 and the lower plate material arrangement portion 3 or through the gap between the plate materials of the lower plate material arrangement portion 3 and reaches the lower side of the upper plate material arrangement portion 2. Further, the air passes through the gap between the adjacent plate members 2A to 2C of the upper plate member arrangement portion 2, and is discharged to the outside of the building ST.

In the upper plate material arrangement portion 2 located at the uppermost part of the building, rainy water tends to enter the room through the gap between the plate materials 2A to 2C as shown by broken line arrows in FIG. However, in the plate members 2A to 2C, the end portions in the lateral direction of the adjacent plate members overlap in plan view, and the downward bent portions 2AD to 2CD are formed at the outer end portions, and the upward bent portions are formed at the central end portions. 2BU and 2CU are formed. The rainwater to be invaded rises while being blocked by the upward bent portions 2BU and 2CU, where separation by inertia is performed. Nevertheless, the rainwater that has passed through the gaps between the plate members 2A to 2C falls on the plate members 3A to 3C of the lower plate member arrangement portion 3, and is finally collected on the central plate member 3A at the lowest position, and the building ST It is discharged from the drainage device at the end.
Thus, in the structure 1 of the present invention, natural ventilation is possible while preventing rainwater from flowing into the room of the building ST. Since the structure 1 is placed at the top of the building ST, the rising airflow smoothly flows to the outside, and efficient ventilation can be performed.
