Equipment can be installed in both living spaces such as living rooms and non-residential spaces such as the ceiling space, but it is installed in non-residential spaces in order to ensure that the living space is as wide as possible. It is preferable. For example, Patent Document 1 discloses a configuration in which an air conditioner as an equipment device is disposed in a ceiling space, and the air conditioner is provided so as to be spanned across a ceiling field as a plurality of beam members. In this configuration, an air conditioner is disposed between adjacent ceiling field edges, and a flange protruding laterally from the air conditioner is placed on the ceiling field edge.

Japanese Patent Laid-Open No. 2001-193221

  However, in a configuration in which equipment is placed between adjacent beams and a flange projecting laterally from the equipment is placed on the beams, the equipment is installed at a higher position than the beams. It has become difficult to do. On the other hand, by installing the equipment on the base plate with the legs attached, and placing the legs on the beam material, the equipment can be installed at a higher position than the beam material. Become. In this configuration, the equipment can be installed at a higher position by increasing the length of the leg. However, there is a concern that the support strength and stability of the legs may be reduced by increasing the length of the legs.

  The present invention has been made in view of the above circumstances, and it is possible to increase the degree of freedom with respect to the height position where the equipment is installed, and to provide a building equipment support structure capable of suitably supporting the equipment. The main purpose is to provide it.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary.

  A device support structure for a building according to a first aspect of the present invention is a device support structure for a building in which a device support for supporting equipment is attached to a beam member below a roof, and the equipment support is configured so that the equipment is A base plate installed on the beam material and supporting the base plate, and the leg is directed both above and below the base plate. It extends over the roof, and is stretched over the roof structure extending along the roof and the beam material.

  According to the first invention, in the configuration in which the equipment is installed in the attic space, the legs extending in the vertical direction are spanned between the roof structure and the beam material. If it is an area | region between, it becomes possible to set the installation height of a mount board suitably. In this case, it is possible to install another facility device below the gantry plate. In addition, even if the length of the leg is increased so that the support strength and stability of the leg are reduced, the upper and lower ends of the leg are held by the roof structure and the beam material. Thus, the gantry plate can be stably supported. Therefore, a freedom degree can be raised about the height position which installs an installation apparatus, and an installation apparatus can be supported suitably.

  In a second invention, in the first invention, the leg portion is extendable in the vertical direction.

  According to 2nd invention, the length dimension of a leg part can be adjusted according to the separation distance of a beam material and a roof structure, ie, the height dimension of an attic space. In this case, since the operator only has to adjust the length of the leg portion with the leg portion placed on the beam material, the degree of freedom regarding the installation position of the equipment base in the horizontal direction can be increased. In other words, for example, in the attic space formed below the inclined roof portion, it is possible to avoid the inconvenience that the installation position of the equipment mount must be set in accordance with the length of the leg portion.

  According to a third invention, in the second invention, the leg portion is placed on the beam member, and the equipment base extends downward from the leg portion, and the position of the leg portion is Has a restricting portion for restricting displacement of the beam member on which the leg portion is installed in the width direction by being caught on the side surface of the beam member.

  According to the third invention, when the operator adjusts the length of the leg while the leg is placed on the beam, an external force in the width direction of the beam is temporarily applied to the leg. Even if it adds, it will be controlled by the control part that the position of a leg part shifts in the width direction of a beam material. In this case, if the legs are not spaced apart from the beam material, the legs are prevented from falling off the beam material. The operation of expanding and contracting can be easily performed.

  In 4th invention, in 2nd or 3rd invention, the said apparatus base has a change means which can change the height position of the said base board with respect to the said leg part.

  According to 4th invention, not only the length dimension of a leg part but the height position of a mount board can be suitably adjusted according to the height dimension of an attic space. In this case, after the legs are attached to the roof structure and the beam material, the height position of the gantry plate can be changed as appropriate according to the installation mode of the attic space or other building equipment.

  According to a fifth invention, in the fourth invention, the mount plate is provided with an insertion hole through which the leg portion is inserted, and the changing means is a height position of the mount plate with respect to the leg portion. Is a fitting member that is detachably fitted from below between the inner peripheral surface of the insertion hole and the outer peripheral surface of the leg portion.

  According to 5th invention, the height position of a mount board can be changed by the easy operation | work which attaches and detaches a fitting member.

  In addition, in the configuration in which the leg portion can be expanded and contracted, the height position of the gantry plate is changed due to the thickness of the leg portion being not uniform or the thickness of the leg portion changing with expansion and contraction. Accordingly, the size of the gap between the outer peripheral surface of the leg and the inner peripheral surface of the insertion hole is considered to change. On the other hand, according to the present invention, the fitting member has a shape that can respond to the change in the size of the gap, or the fitting member having a different shape can be used depending on the change in the size of the gap. Even if the height position of the gantry plate is changed, the gantry plate can be easily fixed to the leg portion.

  In a sixth invention, in any one of the second to fifth inventions, the roof has an inclined inclined roof portion, and the roof structure extends along the inclined roof portion, A plurality of leg portions are arranged side by side along the inclination direction of the inclined roof portion below the inclined roof portion.

  According to the sixth invention, below the inclined roof portion, the height dimension of the attic space decreases as the distance from the building increases. On the other hand, since the legs are made extendable, the length of each leg arranged along the slope direction of the sloped roof is variable according to the height of the attic space. Can be set. Thereby, even if it is a building which has an inclined roof part, the operation | work which installs in the state which spanned the leg part over the roof structure and the beam material can be facilitated.

  In a seventh invention, in any one of the first to sixth inventions, the equipment is installed on the gantry plate, and a second part different from the equipment is provided below the gantry plate. Equipment is installed.

  According to the seventh invention, in the configuration in which the leg portion is spanned between the beam member and the roof structure, both the upper space and the lower space of the device mount can be effectively used as the device installation space.

  According to an eighth invention, in any one of the first to seventh inventions, the leg portion includes a leg main body and an upper joint portion connected to an upper end of the leg main body, and the beam member and the roof The upper joint is disposed between the lower plate and the lower plate overlaid on the upper end surface of the leg body, the upper plate overlaid on the lower surface of the roof structure, and the lower plate. And a connecting part for connecting the upper plate part.

  According to the eighth aspect, since the leg portion is provided between the roof structure and the beam material, the leg portion can be easily fixed to the roof structure body and the beam material. For example, the leg portion can be easily fixed to the roof structure and the beam member by a fixing tool such as a screw. Also, by installing the leg portion so as to be stretched between the roof structure and the beam material, the frictional force between the upper end surface of the leg portion and the lower surface of the roof structure, and the lower end surface of the leg portion The legs can be fixed to the roof structure and the beam material by the frictional force with the upper surface of the beam material.

  In addition, since the upper surface and the lower surface of the upper joint portion are formed by different plate portions, that is, the upper plate portion and the lower plate portion, the operation of attaching the lower plate portion to the leg body, and the upper plate portion as the roof structure It becomes easy to perform the work of attaching to the bracket using a fixing tool such as a screw. That is, it is possible to easily perform an operation of attaching the upper joint portion to the leg main body to produce the leg portion and an operation of fixing the leg portion to the roof structure.

  In a ninth invention, in any one of the first to eighth inventions, a plurality of building units each including a pillar, a ceiling girder connected to the pillar, and a ceiling girder connected to the ceiling girder are combined. Applied to a built unit building, a bundle supporting the roof is installed on the ceiling beam, and the ceiling beam is provided with the legs on the ceiling beam. The beam material is used.

  According to the ninth invention, since the bundle is supported by the ceiling beam and the equipment frame is supported by the ceiling beam, the ceiling beam is different from the configuration in which the ceiling beam supports both the bundle and the device frame. It can suppress that the applied load becomes large excessively. Thereby, an apparatus mount can be suitably installed with respect to a building unit.

  A building equipment support structure according to a tenth aspect of the invention is applied to a unit type building constructed by a plurality of building units having columns and beams, and a building in which an equipment stand for supporting equipment is attached to the beams. The equipment support structure includes: a base plate on which the equipment is installed; a leg portion that is installed on the beam member and supports the base plate; and a lower portion from the leg portion. And a regulating portion that regulates that the position of the leg portion is shifted in the width direction of the beam material on which the leg portion is installed by being caught on the side surface of the beam material. The leg portion is extendable in the vertical direction.

  According to the tenth aspect, it is easy to change the height position of the gantry plate by adjusting the length of the leg. In addition, even when the operator adjusts the length of the leg with the leg resting on the beam, even if an external force in the width direction of the beam is applied to the leg, The restriction part restricts the position of the leg part from shifting in the width direction of the beam member. In this case, if the leg portion is not even spaced upward from the beam material, the leg portion is prevented from being detached from the beam material. Therefore, the leg portion is placed on the beam material while the leg portion is placed on the beam material. The operation of expanding and contracting can be easily performed.

FIG. In FIG. 4, (a) shows the orientation of the gantry plate 42 of the present embodiment, and (b) shows a diagram in which the orientation of the gantry plate 42 is changed. 5A is a plan view and a side view of the device mount 41, and FIG. 5B is a perspective view of the periphery of the leg main body 71. FIG. 6A is a side view of the upper joint portion 72, and FIG. 6B is a perspective view of the upper joint portion 72. FIG.

  As shown in FIGS. 4A and 4B, in the building unit 20 </ b> A, the device mount 41 is installed on the ceiling beams 25 in a state of being spanned over the plurality of ceiling beams 25. . In this case, the ceiling beam 25 corresponds to a beam material.

  As shown in FIG. 4 (a), the device mount 41 is installed such that its longitudinal direction is perpendicular to the longitudinal direction of the building unit 20A. In this case, the short side of the gantry plate 42 is orthogonal to the ceiling beam 25 of the building unit 20A, and the short side is stretched over a plurality of (for example, two) ceiling beams 25. In the gantry board 42, the short dimension is made larger than the separation distance between the ceiling beams 25.

  The installation base 41 can change the installation direction with respect to the ceiling beam 25. For example, as shown in FIG. 4 (b), it can be installed in both directions extending parallel to the short direction of the building unit 20A. In this case, the long side of the gantry plate 42 is orthogonal to the ceiling beam 25 of the building unit 20A, and the long side is stretched over a plurality of (for example, four) ceiling beams 25.

  A plurality of (for example, four) leg portions 43 are provided, and are arranged corresponding to the four corners of the gantry plate 42. Each leg portion 43 is installed on the ceiling beam 25 and has substantially the same width dimension (thickness) as the ceiling beam 25. Incidentally, the separation distance between the leg portions 43 arranged along the short side of the gantry plate 42 is the same as the separation distance between the ceiling beams 25 (for example, 50 cm), and is arranged along the long side of the gantry plate 42. The distance between the leg portions 43 is three times the distance between the ceiling beams 25 (for example, 150 cm). In addition, the leg part 43 may be arrange | positioned in the intermediate position of the longitudinal direction of the mount board 42, the intermediate position of a transversal direction, etc.

  As shown in FIG. 5A, the equipment base 41 includes a reinforcing member 44 that connects adjacent leg parts 43 in addition to the base board 42 and the leg parts 43. The reinforcing member 44 is formed in a long shape from a metal material, a synthetic resin material, or the like, and extends along the longitudinal direction of the gantry plate 42. The reinforcing member 44 is fixed to the lower surface of the gantry plate 42 by a fixing tool such as a bolt.

  The leg portion 43 includes a leg main body 71 as a long member extending in the vertical direction, an upper joint portion 72 connected to the upper end of the leg main body 71, and a lower joint connected to the lower end of the leg main body 71. Part 73. In the leg portion 43, the upper end is formed by the upper joint portion 72, and the lower end is formed by the lower joint portion 73.

  The leg body 71 can be expanded and contracted in the longitudinal direction, and the expanded and contracted state can be held by itself. As shown in FIG.5 (b), the leg main body 71 has the 1st leg material 71a and the 2nd leg material 71b. The first leg member 71 a and the second leg member 71 b are formed in a long shape from a synthetic resin material, a metal material, or the like, and extend along the longitudinal direction of the leg body 71. These leg members 71a and 71b are provided in a state where at least a part of each of the leg members 71a and 71b is overlapped, and can be relatively slid along the longitudinal direction of each other. The length of the leg body 71 increases as the leg members 71a and 71b slide relative to each other in the direction in which the overlapping portions become smaller, and the leg members 71a and 71b increase in the direction in which the overlapping portions become larger. It becomes smaller by relatively sliding.

  The leg members 71a and 71b are each formed in a cylindrical shape, and one end of the second leg member 71b is in a state of entering the internal space of the first leg member 71a. In this case, the outer diameter of the second leg 71b is smaller than the outer diameter of the first leg 71a. In the leg main body 71, one of the leg members 71a and 71b is rotated in a predetermined direction with respect to the other to reduce the overlapping portion, and by rotating in the opposite direction, the overlapping portion is increased. . Specifically, a male screw is formed on the outer peripheral surface of the first leg member 71a, a female screw is formed on the inner peripheral surface of the second leg member 71b, and the first leg member 71a is engaged with the male screw and the female screw. The second leg 71b is connected. In this case, the length dimension of the leg body 71 is maintained unless the leg members 71a and 71b rotate relatively.

  In the leg main body 71, the upper part is formed by the first leg member 71a, and the lower part is formed by the second leg member 71b. Here, the upper joint portion 72 is attached to the upper end portion of the first leg member 71a, and the lower joint portion 73 is attached to the lower end portion of the second leg member 71b. In the first leg 71a, the lower end is opened downward (second leg 71b side), while the upper end is not opened. In this case, the first leg 71a has an upper end surface. Moreover, in the lower side joining part 73, while an upper end is open | released toward upper direction (1st leg material 71a side), a lower end is not open | released. In this case, the second leg member 71b has a lower end surface.

  In the leg main body 71, since the open end of the first leg 71a faces downward, for example, when the open end of the first leg 71a faces upward (the lower end of the second leg 71b is the first leg). Unlike the case of entering the inside of the material 71a), dust or the like is unlikely to collect on the end surface of the open end of the first leg material 71a. Even if dew condensation water is generated in the attic space 19, it is difficult for the dew condensation water to enter the first leg member 71a from the open end of the first leg member 71a.

  In the equipment gantry 41, the leg main body 71 penetrates the gantry board 42, and the gantry board 42 is restricted from moving along the leg main body 71 in this state. An insertion hole 75 through which the leg main body 71 is inserted is formed in the gantry plate 42, and a fitting member 76 such as a “wedge” is formed in a gap between the inner peripheral surface of the insertion hole 75 and the outer peripheral surface of the leg main body 71. Is fitted. The fitting member 76 is formed in a rectangular parallelepiped shape as a whole, and the thickness dimension of the fitting member 76 gradually decreases from one end to the other end. In the fitting member 76, the thickness dimension of the end portion having the larger thickness dimension is larger than the gap dimension between the inner peripheral surface of the insertion hole 75 and the outer peripheral surface of the leg main body 71.

  The fitting member 76 is fitted into a gap between the inner peripheral surface of the insertion hole 75 and the outer peripheral surface of the leg main body 71 so as to fill a part of the gap. In this case, the fitting position of the fitting member 76 can be arbitrarily set according to the installation position of the device base 41, the posture of the worker during the work, and the like. Note that the fitting member 76 may extend along the outer periphery of the leg main body 71. In this case, the fitting member 76 is attached to the leg main body 71, and after positioning the mount plate 42 with respect to the leg main body 71, the fitting member 76 is inserted into the inner peripheral surface of the insertion hole 75 and the outer periphery of the leg main body 71. It is necessary to fit in the gap with the surface.

  In the equipment base 41, changing the fixing position of the base plate 42 with respect to the leg body 71 changes the height position of the base plate 42. The gantry plate 42 is arranged at a higher position when the second leg 71 b is inserted through the insertion hole 75 than when the first leg 71 a is inserted through the insertion hole 75. Become. Here, since the outer diameter of the first leg 71a is larger than the outer diameter of the second leg 71b, the gap dimension between the outer peripheral surface of the leg main body 71 and the inner peripheral surface of the insertion hole 75 is the second leg 71b. Is larger than the case where the first leg 71 a is inserted through the insertion hole 75.

  On the other hand, in the fitting member 76, the thickness dimension of the larger thickness portion is larger than the gap dimension between the outer peripheral surface of the second leg 71b and the inner peripheral surface of the insertion hole 75, By fitting the joint member 76 into the gap between the leg body 71 and the insertion hole 75, the gantry plate 42 can be fixed to the leg body 71 regardless of the height position of the gantry board 42 with respect to the leg body 71. . The fitting member 76 corresponds to a changing means capable of changing the height position of the gantry plate 42 with respect to the leg portion 43.

  As shown in FIG. 6A, the upper joint portion 72 connects the upper plate portion 81 that forms the upper surface thereof, the lower plate portion 82 that forms the lower surface, and the upper plate portion 81 and the lower plate portion 82. And a connecting portion 83. The upper plate portion 81, the lower plate portion 82, and the connecting portion 83 are integrally formed of a synthetic resin material or a metal material. In the upper joint portion 72, the lower surface of the lower plate portion 82 is overlapped with the upper end surface of the leg main body 71 (the upper end surface of the first leg member 71 a), and the upper surface of the upper plate portion 81 is overlapped with the lower surface of the rafter 51. .

  As shown in FIG. 6B, in the upper joint portion 72, the lower plate portion 82 extends in the horizontal direction, and the upper plate portion 81 is inclined with respect to the lower plate portion 82. The upper plate portion 81 has the same inclination angle as the roof gradient, and extends parallel to the rafter 51. The connecting portion 83 includes a first portion 83a extending along the inclination direction of the upper plate portion 81 and a second portion 83b extending in a direction orthogonal to the first portion 83a. The first portion 83a and the second portion 83b stand up from the upper plate portion 81, respectively. The second portion 83 b connects the end portions of the upper plate portion 81 and the lower plate portion 82, and is connected to the lower end portion of the lower plate portion 82. The first portion 83a connects intermediate portions of the upper plate portion 81 and the lower plate portion 82, and the side end portion of the first portion 83a is connected to the plate surface of the second portion 83b.

  The upper plate portion 81 and the lower plate portion 82 are formed with fixing holes 84 through which fasteners such as screws and bolts are inserted, and the upper plate portion 81 is fixed to the rafter 51 using the respective fixing holes 84. The lower plate portion 82 is fixed to the leg main body 71. The lower plate portion 82 is fixed to the leg main body 71 by attaching a fixture inserted through the fixing hole 84 to the upper end portion of the leg main body 71 (the upper end portion of the first leg member 71a). ing.

  The bottom surface of the rafter 51 is formed by a lower flange 51a, and a bolt hole 51b is formed in the lower flange 51a. The fixing hole 84 of the upper plate part 81 and the bolt hole 51b of the lower flange 51a communicate with each other, and the upper plate part 81 is fixed to the lower flange 51a by the bolts inserted through the fixing hole 84 and the bolt hole 51b. Has been. That is, the leg portion 43 is fixed to the rafter 51.

  As shown in FIG. 7, the lower joint portion 73 extends along the lower end surface of the leg main body 71 (the lower end surface of the second leg member 71 b), and extends downward from the joint plate 85. And a restricting portion 86. In the lower joint portion 73, the joint plate 85 is overlaid on the upper surface of the ceiling beam 25 with the leg portion 43 placed on the ceiling beam 25, and the restricting portion 86 is formed on the ceiling beam 25. It is arranged on the side. In this case, the restricting portion 86 restricts the leg portion 43 from being displaced in the width direction of the ceiling beam 25 by contacting the side surface of the ceiling beam 25.

  The joining plate 85 is formed in a plate shape with a metal material, and is fixed to the lower end of the leg main body 71 with a screw or an adhesive. The joining plate 85 is disposed at a position where the center portion of the plate surface overlaps the central axis of the leg main body 71, and the peripheral edge of the joining plate 85 protrudes laterally from the leg main body 71. Note that the joining plate 85 and the second leg member 71b may be integrally formed by integral molding or the like.

  The restricting portion 86 is attached to the leg portion 43 via the joining plate 85. A plurality of (for example, four) restricting portions 86 are arranged below the joining plate 85 and extend downward from the lower surface of the joining plate 85. One restricting portion 86 is arranged on each of the four sides around the central axis of the leg body 71, and the restricting portions 86 are separated from each other. In this case, each restricting portion 86 is in a state of protruding to the side of the leg main body 71. The separation distance between adjacent restricting portions 86 is equal to or larger than the width dimension of the ceiling beam 25, so that the ceiling beam 25 can enter between the adjacent restricting portions 86 from below. Yes. In this case, the area between the adjacent restricting portions 86 is a storage space for storing the ceiling beam 25.

  A plurality of restricting portions 86 provided for one leg portion 43 are included in one set of restricting portions. In a set of restricting portions, a plurality of restricting portions 86 are provided at intervals that allow at least the ceiling beam 25 to be interposed (entered). In this case, each of the restricting portions 86 has the gap in both the first direction and the second direction so that the ceiling beam 25 can be interposed in both the first direction and the second direction orthogonal thereto. Are provided apart from each other.

  When the four restricting portions 86 are aligned two each along the longitudinal direction and the short direction of the device base 41, and the short sides of the base plate 42 are spanned across the plurality of ceiling beams 25. In addition, in both cases where the long side of the gantry plate 42 is stretched over the plurality of ceiling beams 25, the ceiling beam 25 can enter between the adjacent restricting portions 86.

  The restricting portion 86 is formed of an angle material as a steel material. In the restricting portion 86, the end face of the short angle member is joined to the lower surface of the joining plate 85 by welding or the like, and thereby extends downward from the lower surface of the joining plate 85. The restricting portion 86 has a pair of plate portions 88 that are orthogonal to each other, and an intersection of the plate portions 88 is a protruding corner portion of the restricting portion 86. In the protruding corner portion, the plate surfaces (adjacent plate surfaces) of the pair of plate portions 88 are also orthogonal to each other. Each restricting portion 86 is arranged in a state in which the free end of each plate portion 88 is directed to the side opposite to the central axis of the leg portion 43.

  Among the four restricting portions 86, in the pair of restricting portions 86 arranged with the central axis of the leg main body 71 interposed therebetween, the protruding corner portions are opposed to each other. In the adjacent restricting portions 86, the plate surfaces of the plate portions 88 are opposed to each other with the storage space interposed therebetween, and when the ceiling beam 25 is stored in the storage space, the plate surface of the plate portion 88 is the ceiling. It will be in the state which overlapped with the side of small beam 25.

  Returning to the description of FIG. 4, in the equipment base 41, one of the plurality of leg portions 43 is defined as a leg portion 43 </ b> A, and the relationship between the orientation of the leg portion 43 </ b> A and the ceiling beam 25 will be described. Also, here, among the plurality of leg portions 43, those arranged in the leg portions 43 </ b> A along the long side of the gantry plate 42 are referred to as leg portions 43 </ b> B, and are arranged in the leg portions 43 </ b> A along the short side of the gantry plate 42. Let's say what is the leg 43C.

  In FIG. 4A in which the longitudinal direction of the equipment base 41 extends along the ceiling beam 25, the leg portion 43A is disposed near the upper left corner of the base plate 42 in the figure, and the leg portion 43B is It is installed on the same ceiling beam 25 as the leg part 43A, and the leg part 43C is installed on the ceiling beam 25 different from the leg part 43A. On the other hand, in FIG. 4B in which the lateral direction of the equipment base 41 extends along the ceiling beam 25, the leg portion 43A is disposed near the upper right corner of the base plate 42 in the figure. The part 43B is installed on the ceiling beam 25 different from the leg part 43A, and the leg part 43C is installed on the same ceiling beam 25 as the leg part 43A.

  Here, the relationship between the direction of the leg portion 43A and the ceiling beam 25 will be described with reference to FIG. FIG. 8 is a view showing a portion where the leg portion 43A is attached to the ceiling beam 25. As shown in FIG. In FIG. 8, (a1) and (a2) show the case where the longitudinal direction of the equipment base 41 is along the ceiling beam 25, and (b1) and (b2) show the short side of the equipment base 41. The figure in the case where the direction is along the ceiling beam 25 is shown. Further, (a1) and (b1) are plan views of the joining plate 85 as viewed from above, and illustration of the leg portions 43A is omitted. (A2), (b2) is the side view which looked at the leg part 43A from the leg part 43B side.

  In FIG. 8, one of the plurality of restricting portions 86 included in the leg portion 43A is a first restricting portion 86a, and the one disposed on the diagonal line with respect to the first restricting portion 86a is the second restricting portion 86b. And And what adjoins the 1st control part 86a is made into the 3rd control parts 86c and 86d. The third restriction portions 86c and 86d are adjacent to the second restriction portion 86b. Moreover, the 3rd control part 86c is located in a line with the 1st control part 86a along the long side of the mount board 42 (up and down in FIG. 6 (a1), (b1)), and the 3rd control part 86d is a stand. Along the short side of the plate 42 (to the left and right in FIGS. 6 (a1) and (b1)), the first restriction portions 86a are arranged.

  In FIG. 8 (a1), the 1st control part 86a is arrange | positioned at the corner | angular part side of the mount board 42, and the 2nd control part 86b is on the opposite side to the 1st control part 86a across the ceiling beam 25. Has been placed. The third restricting portion 86c is disposed on the opposite side of the second restricting portion 86b across the ceiling beam 25, while being disposed on the same side as the first restricting portion 86a with respect to the ceiling beam 25. Has been. In contrast, the third restricting portion 86d is disposed on the opposite side of the first restricting portion 86a with the ceiling beam 25 interposed therebetween, while the second restricting portion 86b with respect to the ceiling beam 25 Located on the same side.

  In this case, as shown in FIG. 8 (a2), the ceiling beam 25 is located between the second restricting portion 86b and the third restricting portion 86c (between the first restricting portion 86a and the third restricting portion 86d). The joining plate 85 is fixed to the ceiling beam 25 with screws 89 in a state where the upper surface of the ceiling beam 25 overlaps the lower surface of the joining plate 85. The screw 89 is attached to the upper surface portion of the ceiling beam 25 in a state of passing through the joining plate 85. In addition, the ceiling beam 25 is arrange | positioned in the state which orient | assigned the groove part to the side. For this reason, in the ceiling beam 25, the upper surface portion is the upper flange, and the joining plate 85 is fixed to the upper flange.

  Here, the leg 43A is regulated by the first regulating part 86a and the third regulating part 86c to be shifted toward one of the width directions of the ceiling beam 25, and the second regulating part is shifted toward the other. It is regulated by 86b and the third regulating part 86d. On the other hand, the restricting portions 86a to 86d do not restrict the position of the leg 43A from shifting in the longitudinal direction of the ceiling beam 25. 41) can be moved along the longitudinal direction of the ceiling beam 25. The same applies to the other leg portions 43 in the equipment stand 41 such as the leg portions 43B and 43C. Therefore, it is possible to align the equipment base 41 in the longitudinal direction of the ceiling beam 25 while preventing the leg portion 43 from falling off the ceiling beam 25.

  8 (b1) and 8 (b2), the installation direction of the device mount 41 is 90 degrees different from FIG. 8 (a1). In this case, the direction of the ceiling beam 25 with respect to the leg 43A is 90 degrees different from that in FIGS. 8A1 and 8A2, and the ceiling beam 25 is connected to the first restriction part 86a and the third restriction part 86c. Between. Therefore, the leg 43A is regulated by the first regulating part 86a and the third regulating part 86d to be displaced toward one of the width directions of the ceiling beam 25, and the second regulating part 86b is displaced toward the other. And it is controlled by the 3rd control part 86c.

  Here, regarding the positional relationship between the restricting portion 86 and the ceiling beam 25, the other leg portions 43 are the same as the leg portions 43A. For example, regarding the leg portions 43B and 43C, when the regulating portions 86 are the regulating portions 86a to 86d, the arrangement of the regulating portions 86a to 86d is the same as that of the leg portions 43A. In this case, the restriction portions 86a to 86d of the leg portion 43B are arranged at positions along the long side of the gantry plate 42 with respect to the restriction portions 86a to 86d of the leg portion 43A, and the restriction portions 86a of the leg portion 43C. ˜86d are arranged at positions along the short side of the gantry plate 42 with respect to the restricting portions 86a to 86d of the leg portion 43A.

  When the longitudinal direction of the device mount 41 extends along the ceiling beam 25 (in the case of FIG. 4A), the first restricting portions 86a of the leg portions 43A and 43B are combined into one ceiling beam 25. It is lined up along. In this case, since the two first restricting portions 86a arranged at a predetermined interval (separation distance between the leg portions 43A and 43B) are hooked on one ceiling beam 25, 1 is provided for one ceiling beam 25. Unlike the configuration in which only one first restricting portion 86a is hooked, it is possible to prevent the device mount 41 from rotating in the width direction of the ceiling beam 25 with the one first restricting portion 86a as a fulcrum.

  Moreover, in leg part 43A, 43B, each 2nd control part 86b is located in a line along one ceiling beam 25 on the opposite side to each 1st control part 86a. Even in this case, since the two second restricting portions 86b arranged at a predetermined interval are caught by one ceiling beam 25, only one second restricting portion 86b is caught by one ceiling beam 25. Unlike the configuration, the device frame 41 is prevented from being shifted in the width direction of the ceiling beam 25 by rotating the device mount 41 toward the opposite side of the first restricting portion 86a with one second restricting portion 86b as a fulcrum. The

  Similarly, when the transverse direction of the device base 41 extends along the ceiling beam 25 (in the case of FIG. 4B), each of the first restricting portions 86a of the leg portions 43A and 43C has one ceiling. The second restricting portions 86b are arranged along the ceiling beam 25 on the side opposite to the first restricting portions 86a. For this reason, similarly to the case where the longitudinal direction of the device mount 41 extends along the ceiling beam 25, the device mount 41 rotates with one first restricting portion 86a and one second restricting portion 86b as fulcrums. In this way, it is prevented that the ceiling beam 25 is shifted in the width direction.

  Next, the work procedure when installing the equipment mount 41 in the attic space 19 will be described with reference to FIG.

  First, the operator grasps the separation distance between the ceiling beam 25 and the rafter 51 at the planned installation position of the equipment frame 41, and sets the length dimension of each leg 43 of the equipment frame 41 to the ceiling beam 25. The distance from the rafter 51 is set smaller. In this case, in the equipment base 41, the first leg 71 a of the leg portion 43 is inserted into each insertion hole 75 of the base plate 42, and the fitting member 76 is inserted into each insertion hole 75, whereby the base board 42. The height position is temporarily held.

  Thereafter, the leg portions 43 of the device mount 41 are placed on the ceiling beam 25, and the leg portions 43 are extended by rotating the first leg members 71a. Here, in the leg part 43, since the rotation of the leg main body 71 with respect to the ceiling beam 25 is restricted by the restriction part 86 being hooked on the ceiling beam 25, the operator can use the first leg member 71a and the second leg member 71a. Of the legs 71b, only the first legs 71a can be easily rotated without holding the second legs 71b with one hand.

  Then, until the upper joint portion 72 of the leg 43 reaches the lower surface of the rafter 51, the first leg 71a is rotated to extend the leg 43, and the leg 43 is located between the ceiling beam 25 and the rafter 51. Make sure that it is in a stretched state. In this state, the upper end surface of the leg portion 43 (the upper surface of the upper joint portion 72) is pressed from below by the rafter 51, and the lower end surface of the leg portion 43 (the lower surface of the joint plate 85) is above the ceiling beam 25. It is pressed from. For this reason, the leg portion 43 is fixed to the ceiling beam by the frictional force between the upper end surface of the leg portion 43 and the lower surface of the rafter 51 and the friction force between the lower end surface of the leg portion 43 and the upper surface of the ceiling beam 25. 25 and the rafter 51 are restricted from moving.

  By placing each leg portion 43 of the device mount 41 between the ceiling beam 25 and the rafter 51, the device mount 41 can be temporarily fixed to the ceiling beam 25 and the rafter 51. Thereafter, the lower joint 73 is fixed to the ceiling beam 25 and the upper joint 72 is fixed to the rafter 51 using a fixing tool such as a screw or a bolt. At this time, since the leg portion 43 is temporarily fixed, the operator does not have to hold the device base 41 with one hand and hold the position with the other hand while fixing the position with the other hand. The fixing work by the fixing tool can be easily performed with both hands.

  Next, after each fitting member 76 inserted into each insertion hole 75 of the gantry plate 42 is pulled out and the height position of the gantry plate 42 is changed, each fitting member 76 is moved from below to the inner periphery of the insertion hole 75. The gantry plate 42 is fixed to the leg portion 43 by being inserted into and fitted into a gap between the surface and the outer peripheral surface of the leg main body 71.

  Thereafter, an operation of installing the air supply unit 61 below the gantry plate 42, an operation of installing the air conditioner 31 on the gantry plate 42, an operation of connecting the air conditioner 31 and the air supply unit 61 by the air conditioning duct 62, and the like. Do.

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

  In the equipment base 41 that supports the air conditioning equipment 31, since the leg portion 43 is spanned between the ceiling beam 25 and the rafter 51, the base board 42 is set at both the position near the roof 13 and the position near the ceiling 56. It becomes possible to do. Here, since the upper end of the leg part 43 is fixed to the rafter 51, for example, compared with the case where the upper end of the leg part 43 is a free end (when not fixed to the rafter 51), The support strength of the gantry plate 42 can be increased. Therefore, a freedom degree can be raised about the height position which installs the air conditioner 31, and the air conditioner 31 can be supported suitably.

  Since the leg portion 43 can be expanded and contracted, the length dimension of the leg portion 43 can be adjusted according to the separation distance between the ceiling beam 25 and the rafter 51. Therefore, it can be avoided that the installation position of the leg 43 is limited by the separation distance between the ceiling beam 25 and the rafter 51 in the roof inclination direction where the separation distance between the ceiling beam 25 and the rafter 51 is not uniform. This also facilitates changing the installation position of the device mount 41 in the roof inclination direction.

  Since the position of the leg 43 is shifted in the width direction of the ceiling beam 25 by the regulation unit 86, the leg 43 when the leg 43 is expanded and contracted in a state of being placed on the ceiling beam 25. Can be prevented from falling from above the ceiling beam 25. Therefore, the work of adjusting the length dimension of the leg portion 43 according to the separation distance between the ceiling beam 25 and the rafter 51 can be facilitated.

  Since the position of the gantry plate 42 can be changed along the longitudinal direction of the leg portion 43, the height position of the air conditioner 31 is preferably set according to the installation mode of the attic space 19 and the air supply unit 61. Can do. Further, since the leg portion 43 is inserted into the insertion hole 75 of the base plate 42, the fitting member 76 fitted in the gap between the outer peripheral surface of the leg portion 43 and the inner peripheral surface of the insertion hole 75 is attached and detached. Thus, the height position of the gantry plate 42 can be changed. In particular, in the leg part 43, since the outer diameter dimension differs between the 1st leg material 71a and the 2nd leg material 71b, the structure for hold | maintaining the position of the mount board 42 by using the fitting member 76 is used. Can be prevented from becoming complicated.

  Since the air conditioner 31 is installed on the gantry plate 42 and the air supply unit 61 is installed below the gantry plate 42, both the upper space and the lower space of the gantry plate 42 are effectively used as the device installation space. be able to.

  The leg portion 43 is provided between the ceiling beam 25 and the rafter 51 so as to be stretched between the ceiling beam 25 and the rafter 51, so that the leg 43 is fixed to the ceiling beam 25 and the rafter 51 by a bolt or the like. The work of fixing using can be facilitated. Moreover, since the upper joint portion 72 of the leg portion 43 has the upper plate portion 81 and the lower plate portion 82, the upper plate portion 81 is fixed to the rafter 51, and the lower plate portion 82 is fixed to the leg main body 71. It is easy to do.

  Since the gantry plate 42 is supported by the leg portions 43, for example, unlike the configuration in which the gantry plate 42 is supported by the bundle 17, it is possible to suppress an excessive increase in the load applied to the bundle 17.

  Since the restricting portion 86 of the device base 41 is caught on the side surface of the ceiling beam 25, it is possible to prevent the device frame 41 from being displaced in the width direction of the ceiling beam 25 and coming off from the ceiling beam 25. . In this case, when the operator moves the equipment stand 41 on the ceiling beam 25 along the longitudinal direction of the ceiling beam 25, the position of the equipment stand 41 is the width direction of the ceiling beam 25. Therefore, it is not necessary to perform the operation of supporting the device base 41 by hand so that the device base 41 is not displaced. Therefore, it is possible to reduce the work burden when installing the air conditioner 31 on the plurality of ceiling beams 25.

  In the state in which the device mount 41 is installed on the plurality of ceiling beams 25, the first restricting portion 86a can regulate the displacement of the device mount 41 toward one of the width directions of the ceiling beams 25. The second restricting portion 86b can regulate the shift of the position of the device base 41 toward the other side. In this case, since the operator only needs to align the device mount 41 in the longitudinal direction of the ceiling beam 25, the alignment operation can be further facilitated.

  Since the gantry plate 42 of the device gantry 41 is rectangular, the air conditioning device 31 can be properly installed according to its size, shape, application, etc. by appropriately setting the installation direction of the device gantry 41. Moreover, since the first restricting portion 86a and the second restricting portion 86b restrict the displacement of the position of the device mount 41 in the width direction of the ceiling beam 25 regardless of the installation orientation of the device mount 41, Regardless of the installation direction, it is possible to facilitate the alignment work of the device base 41.

  Since both the first restricting portion 86 a and the second restricting portion 86 b are hooked on one ceiling beam 25, the position of the device mount 41 is restricted from shifting in the width direction of the ceiling beam 25. In this case, of course, one ceiling beam 25 enters between the first restricting portion 86a and the second restricting portion 86b of the one leg 43, and the first restriction of the one leg 43 is provided. One ceiling beam 25 enters between the portion 86a and the second restricting portion 86b of the other leg portion 43. For this reason, for example, unlike the configuration in which the ceiling beam 25 on which the first restriction portion 86a is hooked and the ceiling beam 25 on which the second restriction portion 86b is hooked, the first restriction portion 86a and the second restriction portion 86b are different. Is not required to be set according to the positional relationship of the plurality of ceiling beams 25. Therefore, the positional relationship between the first restricting portion 86a and the second restricting portion 86b only needs to match the width dimension of the ceiling beam 25, and the versatility of the device mount 41 can be enhanced.

  By arranging a plurality of leg portions 43 along the longitudinal direction and the short direction of the device base 41, the first restricting portion 86a and the second restricting portion 86b are arranged. In this case, each first restricting portion 86a and each second restricting portion 86b of the plurality of leg portions 43 are hooked on one ceiling beam 25, so that one first restricting portion 86a for one ceiling beam 25 is provided. Unlike the configuration in which the second restricting portion 86b is hooked, the ceiling beam 25 is displaced in the width direction so that the device base 41 rotates with the one first restricting portion 86a or the one second restricting portion 86b as a fulcrum. Can be regulated.

  In one leg portion 43, when the ceiling beam 25 is inserted between the third restricting portion 86c and the first restricting portion 86a, the position of the device mount 41 is shifted from the second restricting portion 86b. When the ceiling beam 25 is inserted between the second restriction portion 86b and the second restriction portion 86b, the position of the device mount 41 is restricted from the same side as the first restriction portion 86a. That is, the third restricting portion 86c serves as both the first restricting portion 86a and the second restricting portion 86b. The same applies to the third restricting portion 86d as well as the third restricting portion 86c. Therefore, the one leg portion 43 restricts the displacement of the ceiling beam 25 in the width direction so that the device base 41 rotates with the one first restricting portion 86a and the one second restricting portion 86b as fulcrums. Can do.

  In one leg portion 43, in a state where the ceiling beam 25 enters between the adjacent restriction portions 86, the plate surfaces of the restriction portions 86 overlap the side surfaces of the ceiling beam 25. In this case, the catching area of the restricting portion 86 with respect to the ceiling beam 25 is increased. For example, the load applied from the restricting portion 86 to the ceiling beam 25 compared to the configuration in which the restricting portion 86 is hooked on the ceiling beam 25 at a point. Is distributed over a wide range, it is possible to suppress a part of the ceiling beam 25 from being recessed or deformed.

  In the configuration in which the leg portion 43 is placed on the ceiling beam 25, the leg 43 falls off the ceiling beam 25 only when the position of the equipment base 41 is slightly shifted in the width direction of the ceiling beam 25. Therefore, the provision of the restricting portion 86 in the leg portion 43 is effective in preventing the detachment of the leg portion 43 from the ceiling beam 25.

  Since the restricting portion 86 is attached to the leg main body 71 via the joining plate 85, the position of the restricting portion 86 can be set regardless of the cross-sectional shape and size of the leg main body 71. For this reason, it can suppress that the shape of the control part 86 becomes complicated by the relationship of the magnitude | size of the leg main body 71 and the ceiling beam 25, etc. FIG. For example, when the leg main body 71 has the same thickness as the ceiling beam 25 or is thinner than the ceiling beam 25, the restricting portion 86 extending downward from the leg body 71 is disposed on the side of the ceiling beam 25. In addition, it is necessary to form the restricting portion 86 so as to wrap around the side of the ceiling beam 25 from the lower side of the leg main body 71, and the shape of the restricting portion 86 becomes complicated.

[Other Embodiments]
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  (1) In the above-described embodiment, the leg 43 is provided in the equipment gantry 41 in a state of penetrating the gantry plate 42, but the leg 43 may not penetrate the gantry plate 42. For example, as shown in FIG. 9, the base plate 42 and the leg 43 are arranged side by side in the longitudinal direction of the base plate 42. In this configuration, the leg portion 43 includes a gantry bracket that protrudes laterally from the leg main body 71, and the gantry plate 42 is placed on the gantry bracket. The gantry plate 42 is fixed to the leg portion 43 by a screw or the like passing through the gantry bracket from below and being driven into the gantry plate 42.

  In the leg portion 43, leg members 71a and 71b are each formed in a square tube shape, and the leg portion 43 has a rectangular shape in plan view as a whole. In this case, the leg portion 43 does not expand and contract by rotating one of the leg members 71a and 71b relative to the other, but expands and contracts by simply sliding and moving at least one of the leg members 71a and 71b. In this configuration, the leg portions 71a and 71b are fixed by a fixing tool such as a screw, whereby the leg portion 43 is held at a predetermined length. In addition, in the leg main body 71, the upper part should just be formed by one of leg material 71a, 71b, and the lower part should be formed by the other. That is, the upper part may be formed of the second leg member 71b and the lower part may be formed of the first leg member 71a.

  Further, the legs 71a and 71b may not be cylindrical. For example, the legs 71a and 71b are both formed in a plate shape. In this configuration, the leg members 71a and 71b are relatively slidable in a state where the plate surfaces are overlapped with each other, and the leg body 71 expands and contracts by the slidable movement of the leg members 71a and 71b. Further, the leg body 71 may have three or more leg members 71a and 71b.

  (2) In the above-described embodiment, the leg portion 43 is fixed to the ceiling beam 25 and the rafter 51 using a fixing tool such as a screw. However, the fixing may not be performed using the fixing tool. Even in this case, the leg portion 43 is provided in a state of being stretched between the ceiling beam 25 and the rafter 51, so that it is fixed to the ceiling beam 25 and the rafter 51. .

  (3) The leg portion 43 may not be provided in a state of being stretched between the ceiling beam 25 and the rafter 51. For example, the leg main body 71 is configured not to expand and contract. In this case, it is preferable that the leg portion 43 is fixed to the ceiling beam 25 and the rafter 51 using a fixing tool such as a screw.

  Further, the leg portion 43 may not be provided between the ceiling beam 25 and the rafter 51. That is, the leg portion 43 may be arranged on at least one side of the ceiling beam 25 and the rafter 51. In this case, it is preferable that the leg portion 43 is fixed to the side surfaces of the ceiling beam 25 and the rafter 51 by a fixing tool such as a screw.

  (4) In the above embodiment, the leg portion 43 is spanned between the ceiling beam 25 and the rafter 51, but the leg portion 43 only needs to be spanned between the beam member and the roof structure. For example, let the leg part 43 be the structure spanned over the ceiling large beam 22 as a beam material, and the main building material 55 which comprises a roof structure.

  (5) In the configuration in which the leg portion 43 is stretched between the beam member and the roof structure, the ceiling 56 may not be formed below the roof 13. For example, in the second floor portion 15, the ceiling beam 25, the ceiling base material 57, and the ceiling surface material 28 are not provided. In this configuration, the attic space 19 is not formed below the roof 13, and the ceiling beam 22 is exposed downward in the second floor portion 15. Even in this case, it is possible to provide the leg portion 43 in a state where it is stretched over the beam material such as the ceiling beam 22 and the roof structure such as the rafter 51.

  (6) In the leg portion 43, the upper joint portion 72 has an upper plate portion 81 and a lower plate portion 82 as long as the upper joint portion 72 has an upper surface superimposed on the lower surface of the rafter 51 and a lower surface superimposed on the upper end surface of the leg main body 71. May not be included. For example, the upper joint portion 72 is formed in a substantially square shape as a whole, and the upper surface of the upper joint portion 72 is inclined according to the inclination angle of the rafter 51. However, in this configuration, in order to fix the upper joint portion 72 to the leg main body 71 with a screw, it is necessary to screw the screw through the upper joint portion 72 and attach it to the leg main body 71. Further, in order to fix the upper joint portion 72 to the rafter 51 with screws, avoiding the position of the screw that has already been driven into the upper joint portion 72, let another screw pass through the lower flange 51a of the rafter 51 and perform the upper joint. It is necessary to wear the part 72.

  (7) In the above embodiment, even when the height position of the gantry plate 42 with respect to the leg portion 43 is changed, the gantry plate 42 is fixed to the leg portion 43 using one kind of fitting member 76. However, a configuration in which a plurality of types of fitting members are selectively used according to the height position of the gantry plate 42 may be employed. Here, in the leg main body 71, since the outer diameter dimension is different between the first leg member 71a and the second leg member 71b, which of the leg members 71a and 71b is inserted into the insertion hole 75 of the mount plate 42. Therefore, the gap dimension between the inner peripheral surface of the insertion hole 75 and the outer peripheral surface of the leg main body 71 is different. Therefore, it is preferable to use a fitting member having a different thickness dimension depending on which of the leg members 71a and 71b is inserted into the insertion hole 75 of the base plate 42.

  (8) In the configuration in which the leg portion 43 is spanned between the beam member and the roof structure, the roof 13 may be a flat roof. Even in this case, if the roof 13 has a water gradient, the separation distance between the beam member and the roof structure is not uniform in the gradient direction, and the separation between the beam member and the roof structure is performed for each leg 43. It is preferable to adjust the length dimension of the leg 43 according to the distance.

  (9) In the device support structure, the gantry plate 42 may be attached to the bundle 17. In this case, the bundle 17 serves as the leg portion 43.

  (10) The leg body 71 may not be able to self-hold the stretched state. Even in this case, since the upper joint portion 72 and the lower joint portion 73 are fixed to the rafter 51 and the ceiling beam 25, the length dimension of the leg body 71 is held by the rafter 51 and the ceiling beam 25. become.

  (11) In the above embodiment, the device mount 41 is installed in one building unit 20 </ b> A. However, the device mount 41 may be installed in a state of being spanned over a plurality of building units 20. Even in this case, with respect to each leg portion 43, if the ceiling beam 25 is interposed between the regulating portions 86, the regulating portion 86 regulates that the position of the device mount 41 is shifted in the width direction of the ceiling beam 25. Will be. Further, since the gantry plate 42 and the reinforcing member 44 are disposed at a position higher than the ceiling beam 22 in a state where the leg portion 43 is installed on the ceiling beam 25, the equipment gantry 41 is attached to the gantry plate 42 and The reinforcing member 44 can be installed in a state of straddling the upper side of the ceiling beam 22.

  For example, as shown in FIG. 10 (a), adjacent building units 20A and 20B are installed in the direction in which the respective long side portions are arranged on the boundary side, and the building units 20A and 20B It is set as the structure by which the equipment stand 41 was installed in the state over the boundary part.

  In this configuration, as in FIG. 3A of the above-described embodiment, the longitudinal direction of the device base 41 extends along the ceiling beam 25 and the two leg portions 43 are arranged along the long side of the base plate 42. One of them is installed on the ceiling beam 25 of the building unit 20A, and the other is installed on the ceiling beam 25 of the building unit 20B. Further, in each of the building units 20 </ b> A and 20 </ b> B, the two leg portions 43 arranged along the short side of the gantry plate 42 are installed on different ceiling beams 25.

  Moreover, as shown to Fig.11 (a), adjacent building unit 20A, 20B is installed in the direction by which each short side part is arrange | positioned at the mutual boundary part side, and those building units 20A, 20B It is set as the structure by which the equipment stand 41 was installed in the state over the boundary part.

  In this configuration, as in FIG. 3B of the above embodiment, the short direction of the device base 41 extends along the ceiling beam 25. Even in this case, as in FIG. 10A, one of the two leg portions 43 arranged along the long side of the gantry plate 42 is installed on the ceiling beam 25 of the building unit 20A, and the other is the building unit. It is installed on the ceiling beam 25 of 20B. On the other hand, in each of the building units 20 </ b> A and 20 </ b> B, the two leg portions 43 arranged along the short side of the gantry plate 42 are installed on the same ceiling beam 25.

  The device mount 41 may be installed in a state of being stretched over the three building units 20. For example, as shown in FIG. 10B, the building units 20A, 20B, and 20C arranged side by side are installed in the direction in which the long side portions are arranged on the boundary side of each other. It is set as the structure by which the equipment stand 41 was installed in the state which straddled both the boundary part of 20A, 20B, and the boundary part of building unit 20B, 20C.

  In this configuration, the longitudinal direction of the equipment frame 41 extends along the ceiling beam 25, and one of the two leg portions 43 arranged along the long side of the frame plate 42 is the ceiling beam 25 of the building unit 20A. The other is installed on the ceiling beam 25 of the building unit 20C. In this case, the leg part 43 is not installed with respect to the ceiling beam 25 of the building unit 20B arranged between the building units 20A and 20C. Incidentally, in this configuration, the building units 20B and 20C are half units in which the length dimension in the short direction is substantially half that of the building unit 20A.

  10 (a), 10 (b), and 11 (a), the device mount 41 straddles the beam assembly where the ceiling beams 22 of adjacent building units 20 are assembled. 41 may be in a state of straddling a column aggregate portion where the columns 21 of the building units 20 arranged side by side are aggregated. For example, as shown in FIG. 11 (b), it is assumed that the equipment base 41 is installed in a state of straddling a column aggregate portion where the columns 21 of the building units 20A, 20B, 20C, and 20D are aggregated. In this configuration, the lateral direction of the device base 41 extends along the ceiling beam 25, and all four legs 43 are installed on the ceiling beams 25 of the different building units 20A to 20D. Yes.

  (12) The restricting portion 86 may be directly attached to the leg main body 71 without using the joining plate 85. For example, the restriction portion 86 is configured to be attached to the lower end surface of the leg main body 71. In this configuration, the leg body 71 has a width dimension larger than that of the ceiling beam 25, and the restricting portion 86 is attached to a portion of the lower end surface of the leg body 71 that protrudes laterally from the ceiling beam 25. Is preferred. Further, the restricting portion 86 may be attached to the side surface of the leg main body 71.

  Further, the leg portion 43 may not have the restricting portion 86. Even in this case, it is possible to suppress the position of the leg portion 43 from being shifted in the longitudinal direction or the width direction of the ceiling beam 25 by providing the leg portion 43 in a state of being stretched between the ceiling beam 25 and the rafter 51.

  (13) In the above embodiment, one leg 43 has the two third restricting portions 86c and 86d, but only one third restricting portion may be provided. Even in this case, in the state where the ceiling beam 25 is inserted between the first restriction member 86a and the second restriction member 86b, the first restriction member 86a and the second restriction member 86b with respect to the ceiling beam 25 Since the third restricting portion is arranged on the same side as one side, the device base 41 rotates in the width direction of the ceiling beam 25 with the one first restricting portion 86a and the one second restricting portion 86b serving as a fulcrum. It can prevent that it shifts.

  (14) The third restriction portions 86c and 86d may not be provided. Even in this case, if a plurality of leg portions 43 are arranged along one ceiling beam 25, a plurality of first restricting portions 86a and a plurality of second restricting portions 86b are spaced at predetermined intervals (separating distance of the leg portions 43). Therefore, it is possible to prevent the device base 41 from rotating in the width direction of the ceiling beam 25 with the first restricting portion 86a or the second restricting portion 86b as a fulcrum.

  (15) In the above embodiment, one leg 43 has both the first restricting portion 86a and the second restricting portion 86b, but only one of the restricting portions 86a and 86b is provided as one leg 43. May have. Even in this case, among the plurality of leg portions 43 arranged along the single ceiling beam 25, the leg portions 43 include the first restricting portions 86a and the second restricting portions 86b. Is shifted toward one side in the width direction of the ceiling beam 25 by the first restricting portion 86a, and being displaced toward the other is restricted by the second restricting portion 86b.

  Moreover, when the leg part 43 which has only the 1st control part 86a among the control parts 86a and 86b and the leg part 43 which has only the 2nd control part 86b are installed on the different ceiling beam 25, respectively. However, the first restricting portion 86a restricts the position of the device mount 41 from being shifted toward one side in the width direction of the ceiling beam 25, and the second restricting portion 86b restricts the position from shifting toward the other.

  (16) In the embodiment described above, all the leg portions 43 have the restricting portion 86 in the device mount 41, but at least one leg portion 43 only needs to have the restricting portion 86. Even in this case, it is possible to restrict the position of the device mount 41 from being shifted in the width direction of the ceiling beam 25.

  (17) In the above embodiment, one leg 43 has one first restricting portion 86a and one second restricting portion 86b. However, one leg 43 includes the first restricting portion 86a and the second restricting portion 86b. You may have two or more control parts 86b.

  For example, as shown in FIGS. 12A and 12B, one leg 43 has two second restricting portions 86b. In this configuration, one of the two second restricting portions 86b is disposed on the opposite side of the other with the first restricting portion 86a interposed therebetween. In this case, storage spaces are formed on both sides of the first restricting portion 86a, and the storage space in which the ceiling beam 25 is inserted is selected in accordance with the position of the ceiling beam 25. It becomes possible. Thereby, it becomes possible to install the device stand 41 in a state where the device stand 41 is stretched over a plurality of sets of the ceiling beam 25 having different separation distances between the adjacent ceiling beams 25. In addition, FIG.12 (b) is the sectional view on the AA line of Fig.12 (a).

  (18) In the above embodiment, the restricting portion 86 is formed of an angle material, but the restricting portion 86 may be formed of a square material. Even in this case, in the restricting portion 86, a protruding corner portion is formed by a portion where adjacent plate surfaces are orthogonal to each other. For this reason, each plate surface of the restricting portion 86 overlaps the side surface of the ceiling beam 25, so that the catching area of the restricting portion 86 with respect to the ceiling beam 25 increases.

  In the restricting portion 86, adjacent plate surfaces do not have to be orthogonal to each other. For example, as shown to Fig.12 (a), the control part 86 may be formed with the column-shaped pin member. Even in this case, a configuration in which the restricting portion 86 extends downward from the leg main body 71 can be realized.

  (19) The joining plate 85 may be rotatable around a rotation axis extending in the vertical direction. In this case, if the 1st control part 86a and the 2nd control part 86b are provided in the joining plate 85 by the predetermined space | interval, these 1st control part 86a and the 2nd control part 86b will be the long side of the mount board 42, or Even if it is the structure located in a line along a short side, the 1st control part 86a and 2nd control are irrespective of the installation direction of the apparatus mount 41 by rotating the joining plate 85 according to the direction of the ceiling beam 25. The ceiling beam 25 can be inserted into the portion 86b.

  (20) The equipment supported by the equipment base 41 may not be the air conditioner 31. Examples of equipment include hot water supply equipment and cogeneration equipment.
