Description

  The present invention relates to a duct installation structure for a unit type building and a unit type building.

  In buildings such as houses, a system that performs air conditioning and ventilation throughout the building using a common indoor unit has been put into practical use. In this system, a ventilation duct is installed in the space behind the ceiling of the building, and the ventilation duct is provided so as to extend to each room in the building, whereby air conditioning and ventilation are performed in each room.

  Here, in a unit type building constructed by combining a plurality of building units, the ceiling back space is divided by ceiling beams and pillars. For this reason, it is difficult to install a ventilation duct so as to straddle the building unit, and there is a disadvantage that it is difficult to introduce a system for air conditioning or ventilation of the entire building.

  At present, as a countermeasure, a through hole is provided in the ceiling beam (or the floor beam on the upper floor), and the ventilation duct is passed through the through hole. However, the pressure loss increases because the duct diameter is reduced at the beam penetration portion of the ventilation duct. Therefore, it is necessary to increase the output of the air conditioner or the ventilator more than the pressure loss, and improvement is desired from the viewpoint of energy saving. In addition, in the configuration in which a through hole for inserting a duct is provided in a ceiling beam or the like, there is an inconvenience that workability is reduced due to forced formation of the hole, and that the beam cannot be penetrated during wide span. And the improvement is desired.

  For example, Patent Document 1 discloses a technique in a unit-type building in which the vicinity of the boundary between adjacent building units is a lowered ceiling, and a ventilation duct is passed through a gap between the lowered ceiling and the ceiling beam.

In the above technique, since a through-hole for inserting a duct provided in a ceiling beam of a building unit can be made unnecessary, inconveniences such as pressure loss of a ventilation duct and deterioration in workability due to forced hole forming work can be avoided. However, the above technique is not a technique that considers optimization of piping efficiency and habitability, and there is room for improvement.
Japanese Patent Laid-Open No. 11-230608

  The main object of the present invention is to provide a unit-type building duct installation structure and a unit-type building capable of improving piping efficiency and habitability.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, in order to facilitate understanding, a corresponding configuration example in the embodiment of the invention is appropriately shown in parentheses, etc., but is not limited to the specific configuration shown in parentheses.

  The present invention is applied to a unit type building (unit type building 10) constructed by combining a plurality of building units (building unit 20), and a ventilation duct used for ventilation, air conditioning or the like in a ceiling space of the unit type building. (Air conditioning duct 32) is installed. And, as a duct installation structure, a storage space portion (storage) that becomes a continuous continuous space through the building units in a building unit having the same ventilation system and each having an indoor opening (air supply port 35) leading to the ventilation duct. A space portion S) was provided, and the ventilation duct was stored in the storage space portion.

  According to the said structure, in the building unit which makes the ventilation system the same, a ventilation duct can be collectively installed in the storage space part which is a continuous space. In this case, the ventilation duct can be easily routed between the plurality of building units. Further, since the storage space portions can be provided in an aggregated manner, it is possible to easily distribute the storage space portions by selecting a place that is not related to the habitability in the unit type building. As a result, it is possible to improve the piping efficiency and the habitability in the unit type building.

  The building units having the same ventilation system are, for example, a plurality of building units in which ventilation is performed by the same indoor unit or ventilation device in the entire building air conditioning system or the entire building ventilation system.

  In the case where the present invention is applied to a unit type building in which building units are combined in at least two rows, the storage space portion may be provided along a boundary portion of the two rows of building units. For example, the storage space may be provided in a straight line along the boundary between two rows of building units.

  In general, it is considered that the boundary part of two rows of building units is often a partition wall part of the living space. Therefore, by providing the storage space portion along the boundary portion of the two rows of building units as described above, the storage space portion is provided along the partition wall portion so as not to stand out from the indoor side. it can. In addition, if the storage space is provided at the boundary between the two rows of building units, the ventilation duct can be easily routed regardless of which of the two rows of building units is routed.

  The storage space portion may be provided below the ceiling beam (ceiling beam 23) of the building unit. In this case, it is considered that the ceiling beam of the building unit is often located at the boundary between adjacent building units and serves as a partition wall portion of the living space. Therefore, by providing the storage space portion along the ceiling beam of the building unit as described above, the storage space portion can be provided along the partition wall portion so as not to stand out from the indoor side.

  It is preferable to provide a falling ceiling (falling ceiling 41) for partitioning the storage space in the ceiling of the building unit. In this case, the storage space can be partitioned with a minimum space.

  It is preferable to provide a blowout port (blowout port 53) of the ventilation duct in the side wall portion between the falling ceiling and the normal ceiling part. In this case, the blowout opening can be provided in the shortest distance from the ventilation duct stored in the storage space, and ventilation can be performed efficiently.

  It is preferable to guide the ventilation duct so as to bypass the pillars in a set part of the pillars (pillars 21) of the plurality of building units. In the case where a plurality of ventilation ducts are provided, the plurality of ventilation ducts may be arranged in the vertical direction to bypass the column. In this case, the ventilation duct can be installed without being obstructed by the pillar of the building unit.

  In the unit type building having the duct installation structure described above, it is preferable that at least a part of the storage space is an article storage room having a size allowing people to enter and exit. In this case, the article storage room is a space provided separately from the human living space, and the ventilation duct is suitable regardless of the habitability in the building by using the article storage room as a storage space portion of the ventilation duct. Can be stored. Even when a falling ceiling is provided, it is possible to suppress a decrease in comfortability.

  In the article storage room, a partition plate for partitioning the storage area of the ventilation duct may be provided. In this case, the storage area for the ventilation duct and the storage area for other various articles can be divided, and the usability is improved.

  In addition, at least a part of the storage space is a temperature-controlled room that is used for storage of articles (for example, food and drink) and breeding pets and maintains a room temperature at a predetermined temperature. It is preferable that air is introduced. In this case, the temperature-controlled room is a space that is provided separately from the living space for people. By using this temperature-controlled room as a storage space for the ventilation duct, the ventilation duct is suitably stored regardless of the habitability in the building. can do. Moreover, the temperature adjustment in a temperature-controlled room can be suitably performed by introduce | transducing air for an air conditioning from a ventilation duct.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings. In this embodiment, it is embodied in a two-story unit type building constructed by a steel frame ramen unit method, and an outline of the unit type building 10 is shown in FIG. The unit type building 10 includes a building body 11 formed by combining a plurality of building units 20 and a roof 12 disposed above the building unit 11.

  FIG. 2 is a perspective view showing the configuration of the building unit 20. In the building unit 20, columns 21 are arranged at the four corners, and the lower end and the upper end of each column 21 are connected by four floor beams 22 and ceiling beams 23, respectively. A rectangular parallelepiped skeleton (frame) is formed by the pillars 21, the floor beams 22, and the ceiling beams 23. The column 21 is made of a square tubular steel material, and the floor beam 22 and the ceiling beam 23 are made of a long steel material having a U-shaped cross section.

  A plurality of floor beams 25 are bridged at predetermined intervals between the floor beams 22 on the long sides of the building unit 20 facing each other. Similarly, a plurality of ceiling beams 26 are bridged at predetermined intervals between the opposed ceiling beams 23 of the long side portion of the building unit 20. Although not shown, the floor material is supported by the floor beam 25. Further, the ceiling face material is supported by the ceiling beam 26.

  In the unit type building 10 of this embodiment, the whole building air conditioning system is respectively employed in the first floor part and the second floor part. The entire building air conditioning system has an indoor unit as an air conditioner provided for each floor, and an air conditioning duct extending from the indoor unit to each building unit (each room). The indoor unit and the air conditioning duct are located behind the ceiling of each floor. Installed in each. However, it is also possible to adopt a configuration in which only one indoor unit is provided in the unit building 10 and air conditioning on the first floor and the second floor is performed by the indoor unit.

  Here, in the case of the unit type building 10, the air-conditioning duct on the first floor is disposed in the first floor ceiling space (between the ceiling floor material and the second floor floor material). Since the building units 20 are divided by the pillars and beams, the air conditioning ducts 32 at the boundary portions of the building units 20 are problematic. In the conventional configuration in which a duct insertion hole is formed in the floor beam and ceiling beam of the building unit, and the air conditioning duct is routed through the duct insertion hole, it is caused by pressure loss due to the reduction of the duct diameter or beam penetration work. There arises a problem that workability is deteriorated.

  Therefore, in the present embodiment, as the installation structure of the air conditioning duct 32, the building units 20 having the same air conditioning system (ventilation system) and each having an air supply port leading to the air conditioning duct 32 are connected continuously through the building units 20. A storage space serving as a space was provided, and the air conditioning duct 32 was stored in the storage space. Details will be described below.

  FIG. 3 is a plan view showing the configuration of the entire building air conditioning system in the first floor portion of the unit type building 10. In FIG. 3, the first floor portion of the building is composed of six building units 20 (building units U1 to U6 in FIG. 3), and among these building units U1 to U6, the rooms requiring air conditioning are U1, U3 and U3. It is U6. The building units U1 to U6 are combined in two rows on the left and right in the figure.

  The indoor unit 31 is installed in a ceiling space of the building unit U5, and a plurality of air conditioning ducts 32 are connected to the indoor unit 31. The air conditioning duct 32 constitutes an air supply duct for supplying air conditioning air to the building units U1, U3 to U6 that require air conditioning. In addition to the air conditioning duct 32, an outside air introduction duct 33 is connected to the indoor unit 31.

  The plurality of air conditioning ducts 32 extending from the indoor unit 31 are led to the building unit that is the air supply destination along the boundary portion between the building units U1 to U6, and an air supply port 35 is provided at the tip of each air conditioning duct 32. It has been.

  Here, the boundary part of each building unit 20 has a descending ceiling, and the air conditioning duct 32 is accommodated in the storage space S on the back of the ceiling formed by the descending ceiling (one point in FIG. 3). Line frame part). The storage space S formed by the falling ceiling is provided to straddle the boundary part of the building units U1, U4, the boundary part of the building units U2, U5, and the boundary part of the building units U3, U6. By utilizing the space S, the air conditioning duct 32 can be easily guided to each building unit that requires air conditioning.

  Details of the installation structure of the air conditioning duct 32 will be described with reference to FIG. 4 is a cross-sectional view showing a boundary portion between the first-floor building unit and the second-floor building unit, which corresponds to a cross-sectional view taken along line AA in FIG. In FIG. 4, reference numeral 37 denotes a floor material on the second floor fixed to a floor beam (not shown here) of the building unit 20, and reference numeral 38 denotes a ceiling beam (shown here) of the building unit 20. It is a ceiling surface material on the first floor fixed to (omitted).

  In FIG. 4, the indoor unit 31 is installed in a gap space (ceiling back space) between the ceiling surface material 38 of the first floor portion and the floor surface material 37 of the second floor portion. A plurality of air conditioning ducts 32 are arranged in the gap space.

  On the first floor, a falling ceiling 41 is provided at the boundary between the left and right building units. The descending ceiling 41 is formed by a ceiling surface material for a descending ceiling (hereinafter referred to as a descending ceiling surface material) 42 provided so as to protrude downward from the ceiling surface material 38. A storage space portion S for storing the air conditioning duct 32 is formed below 23.

  In the storage space S, three air conditioning ducts 32 and one exhaust duct 43 are stored side by side. In this case, each air-conditioning duct 32 extends in the horizontal direction starting from the indoor unit 31, is bent downward before reaching the ceiling beam 23, and is guided into the storage space S. In FIG. 4, the storage space S extends in a direction orthogonal to the paper surface, and the air conditioning duct 32 similarly extends in a direction orthogonal to the paper surface. The dimension of the descending ceiling 41 varies depending on the outer diameter of the duct, the number of ducts, and the like.

  Moreover, since the pillars 21 of the building units 20 gather at the corners of the four building units 20, not only the ceiling beams 23 but also the pillars 21 obstruct the duct operation. Therefore, the air conditioning duct 32 is disposed so as to bypass the column 21. FIG. 5A is a plan view of the building unit on the first floor as viewed from above, and FIG. 5B is a cross-sectional view taken along line BB in FIG.

  In this case, as shown in the figure, the three air conditioning ducts 32 may be distributed and guided to the left and right of the column 21. In FIG. 5, one of the three air conditioning ducts 32 is guided to the left side of the column 21, and the remaining two are guided to the right side of the column 21. The two air conditioning ducts 32 on the right side of the column are arranged side by side so that the air conditioning duct 32 can be accommodated without expanding the falling ceiling 41 in the horizontal direction. According to this configuration, the air conditioning duct 32 can be installed without being disturbed by the pillar 21 of the building unit.

  Next, the installation plan of the falling ceiling in an actual unit type building (house) will be described. FIG. 6 is a diagram illustrating an example of an actual floor plan in the first floor portion of the unit type building. The unit type building shown in FIG. 6 is composed of a total of seven building units, four on the right side and three on the left side (the dotted line in the figure is the boundary between the building units).

  In general, in residential buildings, spaces such as living, dining, and kitchen are spaces where residents usually stay, whereas spaces such as entrances, storage rooms, toilets, and toilets are not spaces where residents usually stay. it is conceivable that. In this sense, assuming that the former space is a residential space and the latter space is a non-residential space, in the unit type building of FIG. 6, the right half of the figure is a residential space and the left half of the figure is a non-residential space. . Moreover, the boundary part of the building unit of two right and left rows is a boundary part of residential space / non-residential space.

  A falling ceiling is provided at the boundary between the living space and the non-residential space, and the storage space S (the central hatched portion in the figure) is formed by the falling ceiling. The storage space S is formed in a straight line along the boundary between the living space and the non-residential space. In this case, in particular, the storage space portion S is provided on the non-residential space side of the partition wall line L that partitions the residential space and the non-residential space. Therefore, narrowing in living space and deterioration of design are suppressed. Also, from the room space side, the falling ceiling is inconspicuous. In addition, the indoor unit 31 is installed in the ceiling back space of the washroom.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  The building units 20 having the same ventilation system and each having an air supply port 35 leading to the air conditioning duct 32 are provided with a storage space portion S that is a continuous space connected through the building units 20, and the storage space portion S is air-conditioned. Since the duct 32 is accommodated, the air conditioning ducts 32 can be installed together. In this case, the air conditioning duct 32 can be easily routed between a plurality of building units. Moreover, since the storage space part S can be aggregated and provided, the storage space part S can be easily distributed by selecting a place (non-residential space) that is not related to the habitability in the unit type building 10. As a result, it is possible to improve the piping efficiency and the comfortability in the unit type building 10. It is possible to realize an optimal duct installation structure for a unit type building that employs a duct type whole building air conditioning and a duct type whole building ventilation.

  Since the storage space portion S is provided along the boundary portion of the two rows of building units, the air conditioning duct 32 can be easily routed regardless of which of the two rows of building units is routed. That is, by arranging the storage space portion S (falling ceiling) almost at the center of the unit type building, the storage space portion S can be shared by all the building units, and the air conditioning duct 32 can be easily guided to any place. Can do. Moreover, a suitable duct piping can be realized with a minimum lowered ceiling.

  Unlike conventional configurations where duct insertion holes are formed in floor beams and ceiling beams of building units, and air conditioning ducts are routed through the duct insertion holes, the output of air conditioners due to pressure loss and beam penetration work are reduced. Problems such as poor workability can be avoided.

The article storage room may or may not be provided with a falling ceiling. Or it is also possible to provide a partition plate (a partition portion at a position lower than the falling ceiling) for partitioning the duct storage portion and the article storage portion below the duct storage portion.

  It is also possible to provide an air outlet for the air conditioning duct 32 in the article storage room. In this case, in the case of an article storage room having a descending ceiling, a blowout port may be provided on the side wall portion between the descending ceiling and the normal ceiling portion.
