Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel capable of reducing the effect of convection caused by a thermal influence from the outside of a building.

[0002]

BACKGROUND OF THE INVENTION Originally, the purpose of a building structure is to block a harsh external environment by a roof or an outer wall and maintain a comfortable internal space.
The building and the environment inside and outside are free to transfer heat as one independent heat system. The movement and propagation of heat are mainly performed by radiation and conduction, and heat is mainly transferred by convection in gases such as liquid and air. The flow of heat in and out of each location, and the storage of heat, is balanced by the heat balance, and heat moves from higher to lower temperatures. The amount of heat transferred is governed by the principle of thermodynamics, which is proportional to the temperature difference.

As a result, in summer, the temperature of the outer grooves such as the roof and side walls of the building rises mainly due to the conduction of the sun's radiation and the high outside temperature, and the conduction moves from the high temperature outside to the low inside, and further to the inside. Heated air which is conducted to the indoor air in contact therewith is light and thus becomes ascending and generates convection.
If there is no phenomenon of convection, the heat input from the outer groove to the internal space will reduce the temperature gradient between the outer groove and the air layer in contact with it, brake the heat input from the outside, and be affected by the external environment Unfortunately, due to the convection phenomenon, the warmed air in contact with the outside ditch of the building escapes and keeps the temperature gradient, so it continues to pump heat like a heat pump and reduce the indoor temperature. To raise.

On the other hand, in the cold season, the temperature of the external environment is generally low and the warm air inside is continuously radiated to the outside. Convection generated in the indoor space carries warm air even during the continuation of this heat transfer,
This is because the temperature difference between the temperature inside the building and the air is preventing the phenomenon from occurring. The measures to cope with the above three aspects of heat transfer are different from each other, and the degree of difficulty is various, including economic judgment. Before air-conditioning equipment became widespread, there was little interest in controlling the temperature of indoor spaces, except for offices and living spaces, and it cannot be said that sufficient attention was paid to building structures. Even if air-conditioning equipment is introduced again, the equipment scale is large and the loss of cooling and heating energy is large unless the heat transfer system is improved, so it cannot always be adopted unconditionally. It ’s almost exaggerated,
Prolonged, difficult, and expensive are inevitable.

In recent years, there has been a great demand for air conditioning, and the power consumption consumed for air conditioning has been increasing year by year, and the increase in energy consumption has increased the dependence on nuclear power and fossil fuels. Neither of these can be continued indefinitely. In particular, because carbon dioxide emissions cause global warming, reducing carbon dioxide emissions by 6% as an international commitment must be complied with as a supreme order. Specifically, a solution that satisfies the following requirements or issues is needed.

(1) Planning with a heat system that conforms to the law of heat transfer (2) Blocking the inflow of heat by partitioning the use space (3) Being applicable to existing buildings (4) Building structure (5) Easy construction and short construction period. (6) Construction work can be performed even when the building is in operation. (7) Measures do not impair the aesthetic appearance. (8) Cooling and heating equipment (9) Standardize based on the principle of industrialization.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is a panel for easily partitioning the interior of a building up and down so that the influence of convection that may occur in an upper space is hardly exerted on a lower space. Therefore, the panel is a partition body having a substantially convection blocking function, and a support portion for simply supporting the partition body,
Wherein the support portion can be attached to a predetermined location inside the building by attaching means. Preferably, the panels may be arranged at predetermined intervals substantially parallel to the backside of the sloping roof. Preferably, the panel comprises a plurality of types of standard panels having different standard dimensions. Preferably, the partition is rollable and / or foldable. Preferably, the partition comprises a double honeycomb structure. Preferably, the partition comprises a single honeycomb structure. Preferably, the partition body is formed of a bellows structure in which predetermined sheet materials are alternately and reversely bent. Preferably, the partition is made of a flexible sheet.
Preferably, the support portion includes a bending prevention member for preventing the panel from hanging. Preferably, the deflection preventing member is made of a metal material. Preferably, the deflection preventing member is made of a wire.

According to the present invention, the following effects can be obtained. In other words, the heat transfer to the indoor use space and the cause that the heat transfer does not stop are due to the convection phenomenon of air, but since it is not possible to stop convection which is a natural pattern,
A space inside the building is vertically divided by panels to prevent heat from flowing into and out of the lower use space by convection, and to stabilize the temperature in the space. The upper space is left as a troposphere, and as the volume decreases, the flow of heat and the convective reaction become more intense, but the heated hot air that is heated rises is exhausted from an exhaust port (roof fan) provided in the building section.

According to the present invention, in the lower use space indoors, the convection that carries heat is prevented from flowing in by the panel, and the temperature does not flow in and out, so that the temperature can be stabilized. The upper convection space is accelerated as the volume is reduced,
The heat is efficiently exhausted from the top exhaust port, which contributes to the improvement of the building's heat balance. The panels are lightweight, flexible and stretchy,
Since it can be freely adjusted to the shape and installation conditions of the installation site, it can be easily installed in a short time. Furthermore, this characteristic has a degree of freedom in shape and dimensions, greatly reduces the dimensional standard, simplifies the layout plan, and omits the original drawing work, and does not require any special consideration and processing in site-based construction.

[0010] Even when used in combination with an air conditioner, the scale of the facility can be reduced by improving the heat balance due to the effect of blocking convection, the operating cost can be reduced, and the economic effect is enormous.

[0011]

An embodiment of the present invention will be described below with reference to the drawings. An embodiment in which the present invention is applied to a factory building will be described in detail as an embodiment. There are various types of factory buildings depending on external factors such as the shape and properties of work objects, location conditions, and the like, and they can be broadly divided into two-story buildings and single-story buildings. Consists of

[0012] The roof has a shape, size, type,
There are many types according to the location, climate, roofing material, etc. As a factory roof, lighting and ventilation are important factors, and the roof 3 of the illustrated building 1 is a so-called gable roof. Building 3 has important points (2 in the figure)
), A roof fan device F for ventilation is attached.

In the illustrated factory building 1 (one-story building + gable roof), a convection cut-off panel is provided at a predetermined interval from the roof on the inner side of the building and substantially parallel to the flowing roof portion (however, those below the building are not parallel). A large number of (hereinafter, panel) Ps are arranged. As a specific arrangement of the panels P, as shown in FIG. 4, the panels P are arranged so as to cover the entire interior of the building in plan view. 4. In FIG.
Indicates that the size (unit standard) is different. That is, for example, 2800 × 2600, 2900 × 2600,
Is 2970 × 2600, is 2800 × 700, is 2390 × 700, is
The panel P of this embodiment is composed of in-house standard products having various dimensions, such as 2375 × 700 and 2970 × 700.

Here, referring to FIGS. 5 to 7 showing a single unit (unit) of the mounted panel P, the panel P has a partition member 7 having a substantially convection blocking function and a support portion 9 for supporting the partition member 7. , And The partition body 7 is composed of a double honeycomb structure 11 in the illustrated example. A double honeycomb structure is composed of two sets of single honeycomb structures (those described later) that are formed by connecting thin sheets of a hexagonal cross-section into a cylinder and connecting them in a row. It consists of a structure as if they were bonded. The double honeycomb structure 11 itself has flexibility (extensibility), and is configured to be folded to one side (in a bellows-like manner) to be compact.

As a specific example (actual example) of the double honeycomb structure 11, a COMFORTEX (US)
CORPORATION). At the lower side of the double honeycomb structure 11, one or more (in the illustrated example, a pair) deflection preventing members 13 (for maintaining the shape) that support the whole from below are arranged.
Are fixed to the ends of the deflection preventing member 13 via the sandwiching plate 15. (Note that the deflection preventing member 13 is embodied as a square pipe made of aluminum in the illustrated example,
It is not limited to this, and can be composed of various materials,
Needless to say, it can be made of materials having various cross-sectional shapes. Further, instead of disposing the deflection preventing member 13 below the structure 11, it can be disposed so as to penetrate in the longitudinal direction of the structure. Alternatively, the bending prevention member 13 may be arranged on the upper side of the structure 11 and a necessary portion of the structure 11 may be fixed to the upper side.

A threaded shaft 17 (M6 long screw bolt) is attached to each of the (four) holding plates 15 so as to extend upward. A py rack (C-shaped clamp member) 19 is connected to the upper end side of the shaft 17,
The py rack 19 is configured to be hooked (attached) to an I-beam 21 constituting a framework (beam) of a roof of a factory building.

In the illustrated embodiment having the above structure, the inside of the roof and the partition 7 (double honeycomb structure 1)
In the space near the attic defined between 1) and 2),
Then, an air flow (convection) occurs as indicated by an arrow. That is, the air warmed in the space near the attic is immediately and efficiently discharged to the outside from the roof fan (exhaust port) F.

The double honeycomb structure 11 (partition body 7) is partitioned by the effect that the heat is circulated and discharged very efficiently, or in addition to this, due to the heat insulation effect due to the presence of air (layer) in the space near the attic. The flow of heat into and out of the substantial interior space of a closed factory is greatly reduced, where convection phenomena do not occur or are very slight. Thereby, the temperature of the substantial internal space of the factory can be maintained extremely stably.

In the above embodiment, the partition 7
As an example, the double honeycomb structure 11 (FIG. 8A) has been described as an example. Instead, the (single) single honeycomb structure 31 (FIG. 8B) as described above is employed. You can also. Further, instead of these, a bellows structure 33 (FIG. (C) in the figure) or a simple sheet (film) 35 (FIG. (D)) in which a predetermined sheet material is alternately and reversely bent can be adopted.

Since the partitioning member 7 has sufficient strength (the function of maintaining the shape) of the deflection preventing member 13, the partitioning member 7 needs to have a corresponding strength, and is made of various materials such as paper, cloth, plastic resin, and thin (non-ferrous) metal plate. Can be configured. Of course, from the viewpoint of lighting, a colorless or colored material that is transparent or translucent is desirable. From the viewpoint of light shielding, a member having no light transmittance is desirable.

When the partition 7 has flexibility or elasticity, there are the following advantages. That is, as shown in FIG. 9 (left hand side), the whole is contracted in a bellows-like manner, which is convenient for transportation and storage. In addition, deployment work can be performed on site for panel installation work, and it is convenient because it is not bulky. Some roofs have curved portions, and the shape can be changed to conform to the curved portions (shape adaptability). For example, in the case of installation and installation in a dome style, this can be performed by using a bending prevention member 13 which is bent as a whole as shown in FIG. 10 (FIG. 9).

Further, the partition member 7 can be easily rolled.
For example, when a flexible sheet material is used, it can be wound round as shown in FIG. 11, which is convenient for transportation and storage as described above. In particular, in the case of this embodiment, it is only necessary to rewind and unfold the necessary length, and then attach it. In other words, it can instantly and easily respond to most dimensional aspects of the site,
It is very convenient for workers and designers.

Further, it is not to be overlooked that the partition member is very light in weight. It is also worthy of evaluation that the partition can be easily and simply and quickly mounted as if a curtain were mounted. In the case where the partition body is formed of a double honeycomb structure or a single honeycomb structure, for example, by mounting a heat insulating material and / or a sound absorbing material to a large number of cascading tubular portions constituting the partition body, It is possible to obtain a very excellent action and effect as a noise countermeasure.

By the way, instead of the above-described configuration in which the panels are arranged substantially in parallel to the flow roof portion of the roof 3, a large number of panels P (the above-described various ones can be operated) are applied to the ceiling wind substantially parallel to the floor. An experiment was conducted on a structure that is arranged so as to be laid in the air (that is, a structure that partitions the building into a troposphere and a use space) (FIG. 12). Even with this structure,
It was confirmed that good results were obtained in terms of maintaining the room temperature stably.

[0025]

As described above, according to the present invention, the interior of the building can be effectively partitioned, and the internal use space can be stably maintained at a temperature with little thermal influence from the outside. it can. In addition, in terms of the installation work, it can be performed very easily and quickly at a low cost, and is very practical and practical.
