Description

  The present invention relates to an installation structure of an air conditioning facility and an installation method of an air conditioner.

  In a building such as a house, a so-called concealed air-conditioning system is known in which an air-conditioning indoor unit is provided in a ceiling space and air-conditioning air is blown out from an air outlet provided in a ceiling material. For example, in a building where an entire building air conditioning system that uses a common air conditioner is installed, the common air conditioner is installed in the ceiling space and extends from the air conditioner to each room in the building. Thus, a plurality of ventilation ducts are installed, and air-conditioned air is supplied from the air conditioner to each living room through each ventilation duct.

  By the way, even in a unit type building constructed by a plurality of building units, an air conditioner may be installed in a space behind the ceiling. The unit type building has a characteristic advantage in that the man-hours at the construction site are remarkably reduced by manufacturing the building unit in advance in the unit factory. Therefore, in order to draw out the advantages of this building unit, attempts have been made to install air conditioners in the unit factory in advance. For example, Patent Document 1 discloses a configuration in which an air conditioner is installed in a ceiling space of a building unit in advance in a unit factory.

Japanese Utility Model Publication No. 4-74223

  By the way, when installing an air conditioner in the ceiling space of a building unit in a unit factory, for example, the air conditioner is lifted and carried into the ceiling space. After that, the air conditioner is moved to a predetermined installation position in the ceiling space (for example, the central position of the space) and installed.

  However, since the air conditioner is generally a heavy object, it is assumed that it takes a lot of labor and difficulty to perform the above series of installation work from the side of the building unit. Also, when installing an air conditioner in a factory, if the air conditioner is installed above the ceiling beam in the ceiling space, the air conditioner protrudes larger than the upper end of the building unit (for example, the ceiling beam). There is a risk that it will be in the way when transporting. Therefore, when installing an air conditioner in a building unit in a unit factory, there is still room for improvement in terms of installation work in the factory and unit transportation work after installation.

  The present invention has been made in view of the above circumstances, and an air conditioner installation structure and an air conditioner capable of suitably performing an air conditioner installation operation in a unit factory and a subsequent transfer operation to a construction site. The main purpose is to provide an installation method.

  In order to solve the above-mentioned problem, the air-conditioning equipment installation structure of the first invention is applied to a unit building constructed by a building unit composed of beams and pillars, and an air conditioner is installed in the ceiling space of the building unit. In the air conditioner installation structure, the air conditioner is provided with a support member extending laterally from two opposing side surfaces, and the support member is mounted on a pair of adjacent ceiling beams in the ceiling space. Thus, the air conditioner is supported so as to be slidable in the longitudinal direction of the ceiling beam.

  According to the present invention, since the air conditioner is supported by the ceiling beam by the support member provided on the side surface thereof, for example, unlike the case where the air conditioner is supported by the ceiling beam at the bottom, the air conditioner for the ceiling beam is provided. The height position of can be lowered. That is, the air conditioner can be installed at a height position that is parallel to the ceiling beam between a pair of adjacent ceiling beams. As a result, it is possible to restrict the air conditioner from projecting above the upper end surface of the ceiling beam. For example, an air conditioner is installed in the building unit manufacturing factory, and the building unit is transported to the construction site in that state. It is convenient to do so. Moreover, since the air conditioner is slidably supported by the support member, it is convenient when changing the position of the air conditioner, which is a heavy object. For example, it is convenient when an air conditioner is once installed on a ceiling beam of a building unit manufacturing factory and then the position is changed. Therefore, the installation work of the air conditioner in the unit manufacturing factory and the subsequent transfer work to the construction site can be suitably performed.

  The air-conditioning equipment installation structure according to a second aspect of the present invention is characterized in that, in the first aspect, the support member or the air conditioner is provided with a restricting portion for restricting a moving direction of the air conditioner.

  According to the present invention, since the moving direction of the air conditioner is restricted by the restriction member provided on the support member or the air conditioner, the air conditioner can be moved to a predetermined position in a stable state. Thereby, inconveniences such as the support member coming off the ceiling beam when the air conditioner slides can be suppressed, and the moving operation of the air conditioner can be suitably performed.

  According to a third aspect of the present invention, there is provided the air conditioning equipment installation structure according to the second aspect, wherein the restricting portion is provided on the support member and extends downward along the side surface of the ceiling beam from the support member. And

  According to the present invention, the air conditioner can be moved along the longitudinal direction of the ceiling beam by sliding the restricting portion extending downward from the support member along the side surface of the ceiling beam to the side surface of the ceiling beam. Thereby, the moving direction of an air conditioner can be specifically controlled.

  According to a fourth aspect of the present invention, there is provided an air-conditioning equipment installation structure according to any one of the first to third aspects, wherein the floor material or ceiling material that divides the ceiling back space where the air conditioner is installed from the indoor space is provided in both An opening communicating with the space is provided, and the opening is provided above or below the range in which the air conditioner can slide.

  According to the present invention, the ceiling material or floor material that partitions the ceiling back space from the indoor space is provided with an opening that communicates both the spaces. Since the opening is provided at an upper position or a lower position in a range in which the air conditioner can slide, the air conditioner can be slid to an upper position or a lower position of the opening. Therefore, the air conditioner can be inspected from the indoor space side through the opening. Here, the range in which the air conditioner is slidable is a slidable range in the longitudinal direction of the ceiling beam on which the support member is placed.

  In addition, if an opening is provided above or below a position different from the installation position where the air conditioner is installed (fixed), the position above or below the opening in the ceiling space is an empty space when the air conditioner is installed. Become. Therefore, in this case, the empty space can be used as a storage space for storing articles.

  According to a fifth aspect of the present invention, there is provided the air conditioning equipment installation structure according to the fourth aspect, wherein a storage container that can be inserted through the opening is detachably provided above or below the opening in the ceiling space. The air conditioner is installed on the side of the storage container.

  According to the present invention, since the storage container is provided above or below the opening in the ceiling space, articles can be stored in the storage container. In addition, since the storage container can be inserted through the opening and is detachable, the storage container can be carried out of the ceiling space through the opening. Thereby, since the air conditioner installed in the side of a storage container can be moved to the upper position or the lower position of an opening part, an air conditioner can be inspected as needed.

  According to a sixth aspect of the present invention, there is provided the air-conditioning equipment installation structure according to any one of the first to fifth aspects, wherein the ceiling beam is prevented from sliding at a predetermined position in the longitudinal direction of the ceiling beam. Means are provided.

  According to the present invention, the sliding movement of the air conditioner can be prevented at a predetermined position in the longitudinal direction of the ceiling beam by the blocking means provided on the ceiling beam. Can be prevented from being slid beyond. Thereby, it becomes possible to perform the operation | work which moves an air conditioner to a predetermined position still more suitably. In addition, it is conceivable that the work of sliding the air conditioner in the unit factory is performed from the side of the building unit. Therefore, even in view of this point, the effect of the present invention is great.

  An air-conditioner installation method according to a seventh aspect of the present invention is an air-conditioner installation method for a building unit composed of a beam and a pillar, and is provided in the air-conditioner and extends laterally from two opposing side surfaces of the air-conditioner. By installing a support member on a pair of adjacent ceiling beams in the ceiling space, the air conditioner is supported between the ceiling beams, and the air conditioner is supported at a predetermined position along the longitudinal direction of the ceiling beams in the supported state. It is characterized by sliding it to

  ADVANTAGE OF THE INVENTION According to this invention, an air conditioner can be supported between each adjacent ceiling beams by installing the supporting member provided in the side surface of the air conditioner in each adjacent ceiling beam. In this case, since the air conditioner is supported on the ceiling beam by the support member provided on the side surface thereof, the height position of the air conditioner with respect to the ceiling beam is different from the case where the air conditioner is supported on the ceiling beam at the bottom. Can be lowered. That is, the air conditioner can be installed at a height position that is parallel to the ceiling beam between a pair of adjacent ceiling beams. As a result, it is possible to restrict the air conditioner from projecting above the upper end surface of the ceiling beam. For example, an air conditioner is installed in the building unit manufacturing factory, and the building unit is transported to the construction site in that state. It is convenient to do.

  Further, since the air conditioner can be slid and moved to a predetermined position along the longitudinal direction of the ceiling beam while being supported between the ceiling beams, the air conditioner which is a heavy object can be suitably moved to the predetermined position. . Therefore, for example, when an air conditioner is installed in a building unit manufacturing factory, the air conditioner is temporarily supported on one end side in the longitudinal direction on the ceiling beam of the unit, and then the air conditioner is supported in the supported state. It can be slid to a predetermined installation position. Therefore, it is possible to suitably perform the installation work of the air conditioner in the unit factory.

  FIG. 5 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 upper end and the lower end of each column 21 are connected by four ceiling beams 22 and floor beams 23, respectively. A rectangular frame (frame) is formed by the pillars 21, the ceiling beams 22 and the floor beams 23. The column 21 is made of a square tube-shaped square steel. Moreover, the ceiling beam 22 and the floor beam 23 are made of channel steel having a U-shaped cross section, and are installed so that the openings thereof face each other. The ceiling large beam 22 (specifically, a grooved steel web) is provided with beam through holes 22a having a diameter of about 100 mm at a plurality of locations.

  A plurality of small ceiling beams 25 are bridged between the large ceiling beams 22 on the long sides of the building unit 20 at predetermined intervals. Similarly, a plurality of floor beams 26 are bridged between the large floor beams 23 on the long sides of the building unit 20 at predetermined intervals. The ceiling beam 25 and the floor beam 26 are horizontally provided at the same interval and at positions corresponding to the top and bottom.

  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 air conditioner provided for each floor, and a ventilation duct extending from the air conditioner to each building unit (each room). The air conditioner and the ventilation duct are respectively installed on the back of the ceiling of each floor. ing. Hereinafter, the configuration of the entire building air conditioning system will be briefly described. In addition, the structure of each whole building air conditioning system of the 1st floor part and the 2nd floor part is substantially the same, and the structure is shown in FIG. FIG. 1 is a plan view showing the configuration of the entire building air conditioning system in the first floor portion. In FIG. 1, for convenience of explanation, each building unit 20 is shown by a simple rectangular frame.

  As shown in FIG. 1, the first floor portion of the building 10 is composed of six building units 20, and one of the building units 20 is provided with an air conditioner 30. A plurality of ventilation ducts 31 are connected to the air conditioner 30, and each of the plurality of ventilation ducts 31 is provided so as to extend to each building unit 20 to be air-conditioned. Specifically, each ventilation duct 31 is led across the building units 20 to be air-conditioned by being provided across the building units 20 through the beam through holes 22 a of the ceiling beam 22. An air supply port 32 is provided at the tip of each ventilation duct 31. As a result, when air-conditioned air is led from the air conditioner 30 to each air supply port 32 through the ventilation duct 31, air-conditioned air is supplied from the air supply ports 32 into each building unit 20 to be air-conditioned. In addition, an outside air introduction duct 33 is connected to the air conditioner 30, and outside air is introduced through the outside air introduction duct 33.

  Next, the details of the installation structure of the air conditioner 30 will be described with reference to FIG. 2A is a plan view showing the installation structure of the air conditioner 30 in the first floor part and the second floor part, and FIG. 2B is a longitudinal sectional view showing the same structure.

  As shown in FIG. 2 (a), a field edge 34 as a ceiling base material is provided along the ceiling beam 25 on the lower surface of the ceiling beam 25 on the first floor. A ceiling material 35 that forms the ceiling surface of the first floor portion is attached by screws or the like. On the other hand, a floor base material 36 is laid on the floor beam 26 on the second floor portion, and a floor finishing material 37 forming a floor surface on the second floor portion is laid on the upper surface. An air conditioner 30 is disposed between adjacent ceiling beams 25 in the space behind the ceiling between the ceiling material 35 on the first floor and the floor base material 36 on the second floor.

  The air conditioner 30 has a substantially rectangular parallelepiped shape as a whole, and is formed in a substantially rectangular shape that is long in the longitudinal direction of the ceiling beam 25 in plan view, as shown in FIG. A stopper 38 is bridged between the adjacent ceiling beams 25 across the air conditioner 30. The stopper 38 is made of, for example, a plate material having an L-shaped cross section, and is fixed to each ceiling beam 25 with a bolt or the like. The air conditioner 30 is installed in a state where the side surface facing the longitudinal direction is in contact with the stopper 38. In the present embodiment, the air conditioner 30 is installed at a substantially central portion in the longitudinal direction of the ceiling beam 25.

  Returning to the description of FIG. 2A, a guide plate 40 is attached to the air conditioner 30. The guide plate 40 is made of a metal plate material, and is attached to both side surfaces of the air conditioner 30 on the ceiling beam 25 side. Here, the guide plate 40 corresponds to a support member. The guide plate 40 is bent and formed on a mounting plate portion 40a attached to the side surface of the air conditioner 30 on the side of the ceiling beam 25 and a side where the lower end portion of the mounting plate portion 40a is separated from the air conditioner 30 (hereinafter referred to as a separation side). As a result, the support plate portion 40b provided above the ceiling beam 25 and the regulating plate portion 40c formed by bending the separation side end portion of the support plate portion 40b downward are provided. The mounting plate portion 40a of the guide plate 40 is fixed to the side surface of the air conditioner 30 on the side of the ceiling beam 25 with bolts or the like.

  Anti-vibration rubber 42 is provided on the lower surface of the support plate portion 40 b of the guide plate 40. The anti-vibration rubber 42 is a vibration damping member for suppressing vibration during operation of the air conditioner 30 from being transmitted to the room through the ceiling beam 25 and the like, and is made of, for example, a rubber material formed in a substantially disk shape.

  A support base 41 made of a metal plate material is provided on the lower surface of the anti-vibration rubber 42. The support base 41 has an upper plate portion 41a whose plate surface is in contact with the lower surface of the anti-vibration rubber 42, and a pair of intermediate portions in which both longitudinal ends of the ceiling beam 25 in the upper plate portion 41a are bent downward. A plate portion 41b, and a pair of lower plate portions 41c whose lower end portions of the intermediate plate portions 41b are bent and formed on the side away from each other and whose plate surfaces are in contact with the upper surface of the ceiling beam 25 Yes. The upper plate portion 41a of the support base 41 is connected to the support plate portion 40b by a bolt 43 with a vibration isolating rubber 42 interposed between the upper plate portion 41a and the support plate portion 40b of the guide plate 40. At this time, the vibration isolating rubber 42 is penetrated by the bolts 43. In such a connected state, the lower plate portion 41 c of the support base 41 is fixed to the upper surface of the ceiling beam 25 by screws 45, whereby the air conditioner 30 is fixed to the ceiling beam 25.

  Note that the air conditioner 30 has its upper end positioned above the upper end of the ceiling beam 22 in this fixed state. Further, the ventilation duct 31 connected to the air conditioner 30 is provided so as to extend over the ceiling beam 25 to the side of the air conditioner 30.

  By the way, in this embodiment, in order to reduce the man-hour at the time of construction, the air conditioner 30 is temporarily installed in the ceiling space of the building unit 20 in the unit factory in advance, and the building unit 20 is moved to the construction site in the temporarily installed state. I am trying to carry it. During the temporary installation, the air conditioner 30 is installed in the building unit 20 so as not to protrude above the height of the upper end of the ceiling beam 22, so that the air conditioner 30 does not hinder the transportation of the building unit 20. Then, at the construction site, the air conditioner 30 temporarily installed in the building unit 20 is once removed, and is finally installed at a predetermined installation position (position shown in FIG. 2A) different from the temporary installation position. Specifically, the air conditioner 30 is permanently installed at a position slightly above the temporary installation position. Therefore, in this embodiment, the installation structure at the time of temporary installation of the air conditioner 30 differs from the installation structure at the time of actual installation. Therefore, an installation structure at the time of temporary installation of the air conditioner 30 will be described below with reference to FIG. 3A is a longitudinal sectional view showing the installation structure when the air conditioner 30 is temporarily installed, and FIG. 3B is a plan view showing the sliding movement of the air conditioner 30. FIG.

  As shown in FIG. 3A, the air conditioner 30 is temporarily installed between adjacent ceiling beams 25 in the building unit 20. At the time of this temporary installation, the support base 41 and the vibration isolating rubber 42 are not attached to the guide plate 40 attached to the air conditioner 30, and the support plate portion 40b of the guide plate 40 is installed on the upper surface of the ceiling beam 25. Yes. Thereby, the air conditioner 30 is supported by the ceiling beam 25. In this supported state, the support plate portion 40 b of the guide plate 40 is fixed to the upper surface of the ceiling beam 25 by screws 47. Thereby, the air conditioner 30 is fixed to the ceiling beam 25.

  In this temporarily installed state, the air conditioner 30 is set such that its upper end is substantially the same height as the upper end of the ceiling beam 22 and its lower end is approximately the same height as the lower end of the ceiling beam 22. ing. In addition, as shown in FIG. 3B, the air conditioner 30 has a side surface facing the longitudinal direction in contact with the stopper 38 in the temporarily installed state. Accordingly, in this case as well, the air conditioner 30 is temporarily installed at a substantially central portion in the longitudinal direction of the ceiling beam 25 in the space behind the ceiling of the building unit 20 as in the case of the main installation shown in FIG. .

  By the way, in the unit factory, a transport facility (such as a belt conveyor) for automatically transporting the building unit 20 is provided, and an operator standing outside the transport facility moves the air conditioner 30 to a temporary installation position in the building unit 20, that is, a plane. It is carried to the approximate center position of the building unit 20 (ceiling space) as viewed. However, since the air conditioner 30 is generally heavy, it is assumed that it takes a lot of labor and difficulty to bring the air conditioner 30 to such a temporary installation position. Therefore, in the present embodiment, the work for carrying the air conditioner 30 to a predetermined temporary installation position is performed by allowing the air conditioner 30 to slide along the ceiling beam 25 in a state where the air conditioner 30 is supported by the ceiling beam 25. We are trying to improve sex.

  Specifically, in the temporarily installed state of the air conditioner 30, the restricting plate portion 40c of the guide plate 40 faces the side surface of the ceiling beam 25 opposite to the air conditioner 30 side. And as shown in FIG.3 (b), when the control board part 40c of the guide board 40 is slid with respect to the same side surface of the ceiling beam 25 in the opposing state, the air conditioner 30 of the ceiling beam 25 is carried out. It is slid along the longitudinal direction.

  Next, a procedure for temporarily installing the air conditioner 30 in the building unit 20 in the unit factory and a procedure for installing the air conditioner 30 in the construction site will be briefly described with reference to FIG. To do.

  First, temporary installation work of the air conditioner 30 in the unit factory will be described. Here, it is assumed that the air conditioner 30 is temporarily installed in the building unit 20 that is transported by a transport facility such as a belt conveyor. Therefore, this work is performed from the side of the building unit 20 by the worker U standing outside the transfer facility.

  First, in the unit factory, the air conditioner 30 is installed between the adjacent ceiling beams 25 on one end side in the longitudinal direction of the ceiling beams 25 (see the dashed line in FIG. 3B). This installation is performed by placing the support plate portion 40b of each guide plate 40 attached in advance to the side surface of the air conditioner 30 on the ceiling beam 25. Thereby, the air conditioner 30 is supported by the ceiling beam 25 in a state where the regulation plate portion 40c of the guide plate 40 faces the side surface of the ceiling beam 25 opposite to the air conditioner 30 side.

  Next, an operation of sliding the air conditioner 30 along the ceiling beam 25 to a predetermined temporary installation position is performed. This work is performed by the operator U pushing the air conditioner 30 toward the center side in the longitudinal direction of the ceiling beam 25. Further, this operation is performed until the air conditioner 30 comes into contact with the stopper 38 attached to the ceiling beam 25 in advance. As a result, the air conditioner 30 is guided to a predetermined temporary installation position (see the solid line in FIG. 3B).

  Next, an operation of fixing the air conditioner 30 to the ceiling beam 25 is performed. This operation is performed by fixing the support plate portion 40 b of the guide plate 40 to the upper surface of the ceiling beam 25 with screws 47. Thereby, the temporary installation work of the air conditioner 30 in the unit factory is completed. Thereafter, the manufactured building unit 20 is transported to a construction site by a truck or the like.

  Next, the main installation work of the air conditioner 30 at the construction site will be described.

  At the construction site, after each building unit 20 on the first floor is installed at a predetermined position, first, the screws 47 fixing the air conditioner 30 are removed, and the air conditioner 30 (including the guide plate 40) is temporarily installed. It is lifted above the position. The support base 41 and the vibration isolating rubber 42 are attached to the support plate portion 40b of the guide plate 40 with the bolts 43 while the air conditioner 30 is lifted, and the air conditioner 30 is in a predetermined installation position in the building unit 20 in the attached state. (See FIG. 2). This installation is performed by placing the lower plate portion 41 c of each support base 41 on the ceiling beam 25.

  In the present embodiment, the main installation position and the temporary installation position of the air conditioner 30 are substantially the same in plan view. That is, only the installation height is different between the main installation position and the temporary installation position of the air conditioner 30, and more specifically, the main installation position of the air conditioner 30 is more than the temporary installation position. It is set upward by the height dimension. Therefore, it is not necessary to carry the air conditioner 30 during the main installation work, and it can be expected that the work is easily performed.

  Next, the lower plate portion 41 c of the support base 41 is fixed to the upper surface of the ceiling beam 25 with screws 47. Thereby, the air conditioner 30 is fixed in a predetermined installation position. Then, each ventilation duct 31 is connected to the air conditioner 30, and the main installation work of the air conditioner 30 is completed.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  By placing the support plate portion 40b of the guide plate 40 provided on the side surface of the air conditioner 30 on the adjacent ceiling beam 25, the air conditioner 30 can be slid along the longitudinal direction of the ceiling beam 25. It was set as the structure supported. In this case, unlike the case where the air conditioner 30 is supported by the ceiling beam 25 at the bottom, the height position of the air conditioner 30 with respect to the ceiling beam 25 can be lowered. It can restrict | limit that the air conditioner 30 protrudes upwards. Therefore, it is convenient when the air conditioner 30 is installed in the building unit 20 in the unit manufacturing factory and the building unit 20 is transported to the construction site in that state. Further, since the air conditioner 30 is slidably supported by the support plate portion 40b of the guide plate 40, it is convenient when changing the position of the air conditioner 30 that is a heavy object. Therefore, for example, when installing the air conditioner 30 in the ceiling back space of the building unit 20 in the unit manufacturing factory, the air conditioner 30 is once installed on the ceiling beam 25 of the building unit 20 and then slides to a predetermined installation position. Can be moved. Therefore, the installation work of the air conditioner 30 in the unit manufacturing factory can be suitably performed.

  The guide plate 40 is provided with a restriction plate portion 40c that extends downward from the support plate portion 40b and faces the side surface of the ceiling beam 25 opposite to the air conditioner 30 side. Therefore, the air conditioner 30 can be slid along the longitudinal direction of the ceiling beam 25 by sliding the regulating plate portion 40 c to the side surface of the ceiling beam 25. Thereby, since the moving direction of the air conditioner 30 can be regulated, the air conditioner 30 can be moved to a predetermined position in a stable state.

  A stopper 38 that blocks the sliding movement of the air conditioner 30 at the temporary installation position was placed between the adjacent ceiling beams 25. Thereby, since the slide movement of the air conditioner 30 is prevented at the temporary installation position by the side surface of the air conditioner 30 facing the longitudinal direction being in contact with the stopper 38, the air conditioner 30 is excessively pushed. Can be prevented from sliding beyond the temporary installation position. Thereby, it becomes possible to perform the operation | work which moves the air conditioning machine 30 to a temporary installation position much more suitably.

[Second Embodiment]
In the first embodiment, the air conditioner 30 can be slid along the ceiling beam 25 while the air conditioner 30 is supported by the ceiling beam 25 when the unit is manufactured in the unit factory. The air conditioner 30 can be slid along the ceiling beam 25 even after the machine 30 is installed in the building 10. Hereinafter, the configuration of the present embodiment will be described based on FIG. 6 with a focus on differences from the first embodiment. FIG. 6A is a longitudinal sectional view showing the installation structure of the air conditioner, and FIG. 6B is a longitudinal sectional view showing the configuration of the ceiling space. In FIG. 6, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 6A, an air conditioner 30 is arranged between adjacent ceiling beams 25 in the ceiling space between the ceiling material 35 on the first floor and the floor material 54 on the second floor. ing. In the present embodiment, a slide plate 50 made of a metal plate material is provided between the lower plate portion 41c of the support base 41 and the upper surface of the ceiling beam 25, and in this respect, the first embodiment is different from the first embodiment. Thus, the installation structure of the air conditioner 30 is different. The slide plate 50 is formed so as to extend along the ceiling beam 25, and specifically has a length dimension slightly longer than the length dimension in the longitudinal direction of the air conditioner 30. The slide plate 50 has a substantially L-shaped longitudinal section, and a support plate portion 50a provided between the lower plate portion 41c of the support base 41 and the upper surface of the ceiling beam 25, and the support plate portion 50a. The guide plate portion 50b is formed such that the separate end portion (the end portion on the side separated from the air conditioner 30) is bent downward. The slide plate 50 has a support plate portion 50 a fixed to the lower surface of the lower plate portion 41 c of the support base 41 by welding, and thereby integrated with the air conditioner 30. Therefore, the air conditioner 30 is installed between the adjacent ceiling beams 25 by supporting the support plate portion 50 a of the slide plate 50 on the ceiling beams 25.

  The support plate portion 50 a of the slide plate 50 is fixed to the upper surface of the ceiling beam 25 by bolts 51. Specifically, as shown in FIG. 6B, the support plate portion 50a is fixed by a bolt 51 at one end in the longitudinal direction. A holding plate 52 is provided at the other end of the support plate 50a in the longitudinal direction. The presser plate 52 is a sheet metal member formed by step bending, and is fixed to the ceiling beam 25 with screws or the like in a state where the lower end surface thereof is in contact with the upper surface of the ceiling beam 22. The presser plate 52 is fixed to the ceiling beam 25 with the plate portion forming the upper end face thereof facing the air conditioner 30 side.
