Description

  The present invention relates to an installation structure for air conditioning equipment.

  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 a unit factory in advance.

  Moreover, when it is set as the structure which installs an air conditioner in the ceiling back space of a building unit, although it becomes a problem how maintenance work of an air conditioner is performed, in the said patent document 1, a ceiling back space is made into the room space above it. A means for providing an opening in the partitioning floor material and performing maintenance work through the opening is shown. In this case, the air conditioner can be maintained by work from the floor.

It is installed on the top. Thereby, the air conditioner 30 is installed between a pair of adjacent ceiling beams 25. And in this installation state, each support plate part 40b of the support plate 40 is being fixed to the upper surface of the ceiling beam 25 with the screw 47, As a result, the air conditioner 30 is being fixed to the ceiling beam 25. In this temporarily installed state, the air conditioner 30 has its upper end set at substantially the same height as the upper end of the ceiling beam 22.

  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 at the construction site will be briefly described with reference to FIGS. To do.

  In the unit factory, first, an operation of temporarily installing the air conditioner 30 in the space behind the ceiling of the building unit 20 is performed. This operation is performed by installing the support plate portion 40b of each support plate 40 attached in advance to the side surface of the air conditioner 30 on a pair of adjacent ceiling beams 25. Thereby, the air conditioner 30 is installed between the adjacent ceiling beams 25 so as not to protrude above the upper end height of the ceiling beam 22 (see FIG. 4).

  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 support 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.

  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 support plate 40) is temporarily installed. It is lifted upward from the installation position. The support base 41 and the vibration isolating rubber 42 are attached to the support plate portion 40b of the support plate 40 with the bolts 43 and nuts 44 while the air conditioner 30 is lifted. Is installed at the installation position (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, each lower plate portion 41 c of the support base 41 is fixed to the upper surface of the ceiling beam 25 by 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. And after completion | finish of this installation work, the building unit 20 which comprises a 2nd floor part is installed above the building unit 20 of a 1st floor part.

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

  An inspection port 38 is provided in the floor plate 37 of the upper floor unit 20 b, and the air conditioner 30 is installed below the inspection port 38. Specifically, by installing the air conditioner 30 on the ceiling beam 25 of the lower floor unit 20 a via the support base 41 and the vibration isolating rubber 42, at least a part of the air conditioner 30 is located at the upper end position of the ceiling beam 22. It protruded upwards. Thereby, access to the air conditioner 30 from the second-floor room side through the inspection port 38 becomes easy, and the maintenance work of the air conditioner 30 can be suitably performed. Further, when installing the air conditioner 30 in the lower floor unit 20a in the unit factory, the air conditioner 30 is installed on the ceiling beam 25 without the support base 41 and the anti-vibration rubber 42 therebetween. The upper end position of the lower floor unit 20a is set to be substantially the same height position as the upper end position of the lower floor unit 20a. Thereby, since it can avoid that the air conditioner 30 obstructs unit conveyance, the building unit 20 can be conveyed suitably. Therefore, from the above, the building unit 20 can be suitably transported to the construction site, and the maintenance work of the air conditioner 30 after installation can be suitably performed.

  A support plate 40 is attached to two opposite side surfaces of the air conditioner 30, and a support base 41 and a vibration isolating rubber 42 are provided between the support plate portion 40 b of the support plate 40 that extends laterally from the side surface and the ceiling beam 25. It was. In this case, since the air conditioner 30 can be installed at a height side by side with the support base 41 and the anti-vibration rubber 42, the installation height of the air conditioner 30 can be set higher than when the air conditioner 30 is installed on the support base 41. Can be lowered. Thereby, since it can restrict | limit further that the air conditioner 30 protrudes above the upper end part of the ceiling girder 22, the air conditioner 30 is installed in the building unit 20 in a unit factory, and the building unit 20 is installed in the construction site in that state. In the case of transporting to, it can be transported more suitably.

  A support base 41 as a pedestal and an anti-vibration rubber 42 are provided on two adjacent ceiling beams 25. That is, since the air conditioner 30 is installed on the ceiling beam 25 which is a part of the building frame via the support base 41 and the vibration isolating rubber 42, the air conditioner 30 which is a heavy object can be stably installed. Can do. Further, since the support base 41 and the anti-vibration rubber 42 are provided on the two adjacent ceiling beams 25, the air conditioner 30 can be installed via the support base 41 and the anti-vibration rubber 42 which are separated from each other. it can. Thereby, compared with the case where the air conditioner 30 is installed via the support stand 41 etc. which were provided on the one ceiling beam 25, the air conditioner 30 can be installed more stably.

  The air conditioner 30 (support plate 40) is installed on the ceiling beam 25 via a vibration-proof rubber 42. Thereby, vibration generated during operation of the air conditioner 30 is suppressed by the anti-vibration rubber 42 from being transmitted to the ceiling beam 25 via the support base 41 and eventually to the ceiling plate 35 supported by the ceiling beam 25. Can do.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) You may enable it to adjust the height position of the air conditioner 30 in the state which supported the air conditioner 30 on the base. A specific example will be described below with reference to FIG.

  As shown in FIG. 7, instead of the support base 41 in the above embodiment, a hydraulic cylinder type lifting device 50 is provided on the ceiling beam 25. The lifting device 50 includes a hydraulic hydraulic pump (not shown) and a lifting platform 51 that moves up and down by driving the hydraulic pump. An anti-vibration rubber 42 is provided on the upper surface of the elevator 51, and a support plate portion 40 b of the support plate 40 is provided on the anti-vibration rubber 42. The support plate portion 40b of the support plate 40 is connected to the lift platform 51 with bolts 53 in a state in which the anti-vibration rubber 42 is interposed between the support plate 40 and the air conditioner 30. 51 is fixed. Therefore, the air conditioner 30 moves up and down by driving the hydraulic pump of the lifting device 50 and moving the lifting platform 51 up and down. Moreover, in this embodiment, unlike the said embodiment, the ventilation duct 31 is connected to the side surface orthogonal to the ceiling beam 25 in the air conditioner 30. FIG. Therefore, it is possible to avoid the ventilation duct 31 from interfering with the floor beam 26 as the air conditioner 30 moves up and down. In addition, although it is good also as a structure which connects the ventilation duct 31 to the side surface by the side of the ceiling beam 25 in the air conditioning machine 30 similarly to the said embodiment, when raising the air conditioning machine 30, the ventilation duct 31 is previously connected to the air conditioning machine 30. It is necessary to remove it from.

  The second-floor room is provided with an operation unit (not shown) operated by the user and a control means (not shown) for driving and controlling the hydraulic pump based on the operation of the operation unit. Thereby, the air conditioner 30 is raised / lowered based on the raising / lowering operation with respect to an operation part. The driving means for raising and lowering the air conditioner 30 may be a pneumatic or hydraulic pump, or an electric driving unit such as a motor, instead of a hydraulic pump.

  In the above configuration, the height of the air conditioner 30 is set by the lifting device 50, the lower position (the position indicated by the solid line in FIG. 7) where the air conditioner 30 is located at the approximate center in the height direction in the interstory space K, and the support plate.
