Description

The present invention relates to a frame that supports a concealed air conditioner and a construction method using the same.

Conventionally, an air conditioner concealed in a ceiling space is known (for example, Patent Documents 1 and 2). This type of air conditioner includes an air conditioner body that is supported by hanging bolts hanging from the ceiling slab, a blowout unit that is attached to the blowout part of the air conditioner body, and an intake part of the air conditioner body. Some are equipped with an air conditioner to be mounted. For example, the main body of the air conditioner is equipped with a heat exchanger, a fan, etc., and adjusts the air taken in from the intake unit to blow it out from the outlet unit. The blowout unit is a unit for guiding the air blown out from the blowout portion of the main body of the air conditioner into the duct and supplying it into the room. The intake unit is a unit for supplying indoor or outdoor air to the main body of the air conditioner. Such an outlet unit and an intake unit are usually mounted on the main body of the air conditioner at the construction site. However, the intake unit may not be attached to the air conditioner body, for example, when the air conditioner body takes in air from the ceiling space for adjustment.

FIG. 11 is a diagram showing a construction method of a conventional concealed air conditioner. Note that FIG. 11 illustrates a case where the intake unit is not attached to the air conditioner main body 310. In this construction method, as shown in FIG. 11A, the operator first lifts the air conditioner main body 310 to a position near the ceiling structure such as a ceiling slab, and a hanging member 9 such as a hanging bolt hanging from the ceiling structure. The air conditioner main body 310 is attached to the ceiling. After that, the operator mounts the mounting portion 321 of the blowing unit 320 on the blowing portion 311 of the air conditioner main body 310 suspended by the hanging member 9. For example, the mounting portion 321 of the blowout unit 320 is inserted and mounted inside the blowout portion 311 of the air conditioner main body 310. If the mounting portion 321 of the blowout unit 320 is simply inserted inside the blowout portion 311 of the air conditioner main body 310, the blowout unit 320 is separated from the air conditioner main body 310 due to wind pressure when the air conditioner main body 310 is operated. There is a possibility that it will end up. In order to prevent this, conventionally, after the mounting portion 321 of the blowout unit 320 is inserted inside the blowout portion 311 of the air conditioner main body 310, as shown in FIG. 11B, with respect to the outer peripheral surface of the blowout portion 311. The work of driving the screw 330 is performed. The screw 330 is for integrating the blowout portion 311 and the mounting portion 321 to prevent the blowout unit 320 from being separated from the air conditioner main body 310. However, it is not possible to prevent the blowout unit 320 from coming off with only a few screws 330. Therefore, in order to prevent the blowout unit 320 from coming off by the screw 330, it is necessary to drive dozens of screws 330 along the periphery of the blowout portion 311. When dozens of screws 330 are driven in this way, the state shown in FIG. 11C is obtained.

Next, as shown in FIG. 11 (d), the worker winds the heat insulating material 340 for preventing dew condensation around the blowout portion 311 into which the screw 330 is driven. When the heat insulating material 340 is wound around the blowout portion 311, the state shown in FIG. 11 (e) is obtained. After that, the operator attaches the suspension member 9 to the blowout unit 320 as shown in FIG. 11 (f) to complete the installation of the air conditioner.

However, in the conventional construction method described above, after the mounting portion 321 of the blowout unit 320 is inserted inside the blowout portion 311 of the air conditioner main body 310, dozens of screws 330 are attached to the outer peripheral surface of the blowout portion 311. It is necessary to perform the driving work as aerial work. At this time, the operator needs to drive the screws 330 at substantially equal intervals along the outer peripheral surface of the blowout portion 311, and it takes time to drive the screws 330. Especially in the case of aerial work, there is a problem that the work efficiency is very poor because the work space is narrow and there are restrictions on the operations that the worker can perform.

Further, in the above-mentioned conventional construction method, after driving the screw 330, it is necessary to perform the work of involving the heat insulating material 340 around the blowout portion 311 as an aerial work. Also at this time, the operator needs to wind the heat insulating material 340 so as to come into contact with the outer peripheral surface of the blowout portion 311, and there is a problem that it takes time to wind the heat insulating material 340.

On the other hand, as a construction method different from the above-mentioned construction method, for example, the work of assembling the air conditioner by attaching the blowout unit and the intake unit to the blowout portion and the intake portion of the air conditioner main body on the floor or the gantry is performed on the floor surface. A construction method performed as a work has been proposed (for example, Patent Document 3). In this construction method, after assembling the blowout unit and intake unit to the air conditioner body by floor work, the air conditioner in which the blowout unit and intake unit are integrated is lifted to a position near the ceiling structure, and the air conditioner body, The air conditioner is installed in a state of being suspended from the ceiling structure by attaching suspension members such as suspension bolts to each of the blowout unit and the intake unit as work at a high place. In such a construction method, the work of driving a large number of screws into the blowout portion of the air conditioner main body and the work of involving the heat insulating material can be performed as floor work, so that the work efficiency is improved.

Japanese Unexamined Patent Publication No. 7-71789 Japanese Unexamined Patent Publication No. 2001-330272 Japanese Unexamined Patent Publication No. 2011-85348

However, even if the conventional method as in Patent Document 3 is adopted, there are the following problems.

The first problem is that when the air conditioner in which the blowout unit and the intake unit are integrated is installed in a state of being suspended from the ceiling structure, the suspension bolts are provided for each of the air conditioner body, the blowout unit and the intake unit. It is necessary to attach a hanging member such as a high-altitude work. As the number of suspension members that must be installed in aerial work platforms to install an air conditioner increases, the efficiency of aerial work platforms decreases accordingly. Therefore, the conventional method of attaching the suspension member to each of the air conditioner main body, the blowout unit, and the intake unit at a high place still has a problem of poor work efficiency. Further, in the case of a structure in which a suspension member is attached to each of the blowout unit and the intake unit to support the blowout unit and the intake unit in a suspended state from the ceiling structure, there is also a problem that the space above the blowout unit and the intake unit cannot be effectively utilized. In other words, if there are obstacles such as beams and pipes in the ceiling space where the blowout unit and intake unit should be installed, the blowout unit and intake unit cannot be installed in a suspended state below those obstacles. ..

The second problem is that the air conditioner main body has a fragile outlet and intake unit, so the air conditioner is equipped with the outlet unit and intake unit attached to the outlet and intake unit of the air conditioner body. If only the main body of the air conditioner is supported and lifted when the air conditioner is lifted, the load of the blowout unit and the intake unit may damage the blowout portion and the intake portion. In order to prevent this, when lifting the air conditioner, it is necessary to lift each of the air conditioner, the blowout unit and the intake unit evenly. Therefore, for example, the air conditioner main body, the blowout unit, and the intake unit must be lifted simultaneously and evenly by using a plurality of elevators, and there is a problem that efficient lifting work cannot be performed.

The third problem is that although the side surface of the air conditioner main body is provided with a connecting portion for connecting the suspension members, the position of the connecting portion is fixed, so that the air conditioner is pre-attached to the ceiling structure. If the position of the hanging member deviates from the position of the connecting portion, the air conditioner main body cannot be suspended by using such a hanging member. In this case, the worker needs to re-install the suspension member in the ceiling structure by using a post-construction anchor or the like so as to match the position of the connecting portion, and there is a problem that the work efficiency is significantly lowered.

The fourth problem is that the above air conditioners are generally renewed after a certain period of about 10 to 15 years has passed since the construction, and new air conditioners installed at the time of renewal If the size is reduced, the hanging member used before the renewal cannot be reused. Therefore, when the worker updates the air conditioner, it is necessary to re-install the suspension member in the ceiling structure according to the size of the new air conditioner, which causes a problem that the work efficiency is lowered. In particular, such renewal work is often performed at the timing when the occupants are replaced, and it is necessary to complete the work in a short period of time, so improvement in work efficiency is required.

Therefore, the present invention has been made to solve the above-mentioned problems, and the gantry and the gantry that can remarkably improve the work efficiency when constructing a concealed air conditioner and effectively utilize the ceiling space. It is an object of the present invention to provide a construction method using it.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the drawings referred to below, members that are common to each other are designated by the same reference numerals, and duplicate description thereof will be omitted.

FIG. 1 is a perspective view showing a gantry 1 according to an embodiment of the present invention. FIG. 2 is a diagram showing an example of a mode in which the gantry 1 supports the concealed air conditioner 100. The gantry 1 is for supporting the concealed air conditioner 100, and is installed in a state of being suspended from the ceiling structure together with the air conditioner 100 while supporting the air conditioner 100.

As shown in FIG. 2, the air conditioner 100 includes an air conditioner main body 110, an outlet unit 120, and an intake unit 130. For example, the air conditioner main body 110 is sandwiched in the center of the air conditioner 100. The intake unit 130 is arranged on the front side and the back side of the air conditioner main body 110. The air conditioner main body 110, the blowout unit 120, and the intake unit 130 are carried into the construction site in a separated state. Therefore, the worker integrally assembles the air conditioner main body 110, the blowout unit 120, and the intake unit 130 at the construction site to create the air conditioner 100, and installs the air conditioner 100 in the ceiling space. .. At this time, the gantry 1 shown in FIG. 1 is used. That is, the gantry 1 can efficiently perform the work of integrally assembling the air conditioner main body 110, the blowout unit 120, and the intake unit 130 by the operator and the work of installing the air conditioner 100 in the ceiling space. Is what you do.

In the air conditioner main body 110, for example, the intake unit 130 is mounted on the back side, and the blowout unit 120 is mounted on the front side. Further, the air conditioner main body 110 is provided with connecting portions 113 for connecting bolts and the like at a plurality of locations on the left and right side surfaces (two locations on the left side surface and two locations on the right side surface in the present embodiment, for a total of four locations). A heat exchanger, a fan, and the like are provided inside the air conditioner main body 110. Therefore, on one side surface of the air conditioner main body 110, a refrigerant pipe connection portion for connecting the refrigerant pipe, a drain pipe connection portion for connecting the drain pipe, a power cable connected to an external power source, and the like are provided. ..

The air conditioner main body 110 has a blowout portion 111 on the front side on which the blowout unit 120 is mounted. The blowout portion 111 is formed as, for example, a square tubular opening frame in which the edge portion of the rectangular blowout outlet is projected toward the front side by a predetermined length. The blowout unit 120 is attached to the blowout portion 111. Further, the air conditioner main body 110 has an intake unit 112 on the back side on which the intake unit 130 is mounted. Like the outlet portion 111, the intake portion 112 is also formed as, for example, a square tubular opening frame in which the edge portion of the rectangular intake port is projected toward the back surface side by a predetermined length. An intake unit 130 is attached to the intake unit 112. The air conditioner main body 110 draws air from the intake unit 112, after heat exchange with the sucked air and the refrigerant, blowing air from the blowing unit 111.

As shown by the arrow F1, the blowout unit 120 is attached to the blowout portion 111 of the air conditioner main body 110. The blowout unit 120 has a connection portion 121 that can be inserted inside the blowout portion 111. The connecting portion 121 is formed as, for example, a square tubular opening frame in which the edge portion of the rectangular opening is projected toward the back surface side by a predetermined length, and the outer size is slightly smaller than that of the blowing portion 111. Therefore, the blowing unit 120 is attached to the air conditioner main body 110 by inserting the connecting portion 121 inside the blowing portion 111. After the blowout unit 120 is attached to the blowout portion 111, a large number of screws may be driven around the blowout portion 111 to reinforce the blowout unit 120 so that the blowout unit 120 does not separate from the blowout portion 111. good. However, in the present embodiment, reinforcement with screws is not essential by constructing the air conditioner 100 using the gantry 1 described in detail later.

Further, the blowout unit 120 has a connection portion 122 for connecting various types of ducts on the outer peripheral surface thereof. At least one connecting portion 122 may be provided with respect to the blowing unit 120, and a plurality of connecting portions 122 may be provided. Further, the duct connected to the connecting portion 122 may be a flexible one or a steel plate one. By connecting a duct that connects to the indoor space to such a connecting portion 122, the blowing unit 120 can guide the air blown from the air conditioner main body 110 into the duct and supply it to the indoor space. become. The duct connected to the connecting portion 122 may be branched into a plurality of ducts in the middle.

A T-shaped mounting member 140 is attached to the upper ends of the left and right side surfaces of the blowing unit 120, for example, as shown in FIG. The mounting member 140 is mounted by an operator using, for example, a screw or the like at a construction site. The upper plate portion of the mounting member 140 projects further sideways from the side surface of the blowout unit 120, and a hole 141 for connecting a bolt or the like is formed in the protruding portion.

The intake unit 130 is attached to the intake portion 112 of the air conditioner main body 110 as shown by the arrow F2. The intake unit 130 has a connection portion 131 that can be inserted inside the intake portion 112. The connecting portion 131 is formed as, for example, a square tubular opening frame in which the edge portion of the rectangular opening is projected toward the front side by a predetermined length, and the outer size is slightly smaller than that of the intake portion 112. Therefore, the intake unit 130 is attached to the air conditioner main body 110 by inserting the connection portion 131 inside the intake portion 112.

Further, the intake unit 130 has a connecting portion 132 on its side surface. For example, a duct connecting to the outside or the inside of the room can be connected to the connection part 132. In this case, the intake unit 130 can guide the outdoor or indoor air to the air conditioner main body 110 through the duct. However, nothing needs to be connected to the connection portion 132. In this case, the intake unit 130 can take in the air in the ceiling space from the opening of the connection portion 132 and guide the air to the air conditioner main body 110. When the air conditioner main body 110 takes in the air in the ceiling space and exchanges heat, the intake unit 130 does not have to be particularly mounted.

Similar to the blowout unit 120, the intake unit 130 has a T-shaped mounting member 140 attached to the upper ends of both left and right side surfaces thereof, for example, as shown in FIG. The mounting member 140 is also mounted by an operator using, for example, a screw at a construction site. The upper plate portion of the mounting member 140 projects further sideways from the side surface of the intake unit 130, and a hole 141 for connecting a bolt or the like is formed in the protruding portion.

The air conditioner 100 as described above is supported by the gantry 1. As shown in FIG. 1, the gantry 1 is attached to a frame frame body 2 formed by assembling a plurality of frame materials 11, 12, 13, 14, 15, 16 in a rectangular shape, and the frame frame body 2. The first support member 3 that supports the side surface of the air conditioner main body 110, the second support member 4 that is attached to the frame frame 2 and supports the blowout unit 120, and the intake unit 130 that is attached to the frame frame 2 It is configured to include a third support member 5 to support and a connecting member 6 for connecting the hanging member 9 such as a hanging bolt to the frame body 2.

First, the frame frame 2 will be described. In the example of FIG. 1, the frame frame 2 is composed of six frame members 11, 12, 13, 14, 15, and 16. However, the number of frame materials is not limited to six, and may be four or more. That is, if there are at least four frame materials, the rectangular frame frame body 2 can be formed. In the example of FIG. 1, the frame frame body 2 has an outer frame composed of four frame members 13, 14, 15 and 16, and an inner frame composed of two frame members 11 and 12.

Of the six frame materials, the four frame materials 11, 12, 13, and 14 arranged along the X direction are arranged above the two frame materials 15, 16 arranged along the Y direction. It constitutes the upper frame material. In the following, the frame materials 11, 12, 13, 14 will be referred to as upper frame materials 11, 12, 13, 14. These upper frame members 11, 12, 13, and 14 are arranged in a state parallel to each other. Further, the two frame members 15 and 16 arranged along the Y direction are arranged below the upper frame members 11, 12, 13 and 14, and form the lower frame member. In the following, the frame materials 15 and 16 will be referred to as lower frame materials 15 and 16. These lower frame members 15 and 16 are also arranged in a state parallel to each other. Then, the upper frame members 11, 12, 13, 14 and the lower frame members 15.16 are assembled in a grid shape to form a rectangular frame frame body 2. That is, the upper frame members 11, 12, 13, 14 and the lower frame members 15, 16 are arranged so as to be orthogonal to each other, and the orthogonal connecting member 20 is attached to the intersecting portion thereof to maintain the orthogonal state with each other. It is configured as follows.

Further, in the frame frame body 2 of the present embodiment, of the four upper frame members 11, 12, 13, and 14, the two upper frame members 11 and 12 arranged in the center are the other two upper frames. It is formed to be longer than the members 13 and 14, and is configured such that both end portions of the two upper frame members 11 and 12 protrude from the outer frame at the center of the frame frame body 2. This is because connecting members 6 for connecting the suspension members 9 are provided at both ends of the central upper frame members 11 and 12. That is, the two upper frame members 11 and 12 in the center of the frame body 2 have a length that matches the installation interval of the hanging members 9 hanging from the ceiling structure such as the ceiling slab, so that the other two upper frames It is formed longer than the frame materials 11 and 12. However, the present invention is not limited to this, and for example, four upper frame members 11, 12, 13, and 14 may all have the same length.

Then, in the gantry 1 of the present embodiment, the first support member 3, the second support member 4, and the third support member 5 are attached to the lower frame members 15 and 16. Therefore, the air conditioner 100 is supported by the frame body 2 by the first support member 3, the second support member 4, and the third support member 5 attached to the lower frame members 15 and 16. Further, as described above, the connecting member 6 is attached to the upper frame members 11 and 12. The gantry 1 is supported by a hanging member 9 such as a hanging bolt via a connecting member 6 of the upper frame members 11 and 12.

FIG. 3 is a diagram showing a configuration example of the upper frame members 11, 12, 13, 14 and the lower frame members 15, 16. As shown in FIG. 3A, the frame material has a configuration in which flat plates of a pair of shaped steels 31 and 32 such as lip channel steel or light channel steel are connected to each other at predetermined intervals so as to face each other. .. For example, the pair of shaped steels 31 and 32 are connected as shown in FIG. 2 (b). That is, the pair of shaped steels 31 and 32 having the same length have holes 31a, 31b, 32a and 32b at both ends of which the bolts 35 are inserted, and the holes 31a, 31b, 32a and 32b have holes 31a, 31b, 32a and 32b. The bolts 35 are inserted, and the nuts 36 are fastened to the tips of the bolts 35 to connect them to each other. At this time, by inserting a cylindrical spacer 34 into the shaft portion of the bolt 35 between the shaped steels 31 and 32, slits 18 at predetermined intervals are formed between the shaped steels 31 and 32. The distance between the slits 18 is a distance through which bolts included in the first support member 3, the second support member 4, the third support member 5, and the like can be inserted. Therefore, each of the upper frame members 11, 12, 13, 14 and the lower frame members 15, 16 can be attached by inserting bolts or the like at arbitrary positions of the slit 18 extending from one end to the other end. The upper frame members 11, 12, 13, 14 and the lower frame members 15, 16 formed in this way are made of, for example, aluminum shaped steels 31, 32. Since the aluminum shaped steels 31 and 32 are lightweight, they are easy to handle even when assembled as the upper frame materials 11, 12, 13, 14 and the lower frame materials 15, 16 and are excellent in work efficiency.

Next, FIG. 4 is a diagram showing a configuration example of an orthogonal connecting member 20 that connects the upper frame members 11, 12, 13, 14 and the lower frame members 15, 16 in an orthogonal state. FIG. 4 shows an example of connecting the upper frame material 11 and the lower frame material 16 as an example. The orthogonal connecting member 20 is a member that connects the upper frame member 11 and the lower frame member 16 in a state of being vertically overlapped with each other in an orthogonal state. The orthogonal connecting member 20 includes an orthogonal holding metal fitting 42 arranged between the upper frame material 11 and the lower frame material 16, a first metal fitting 41 arranged on the upper surface side of the upper frame material 11, and the lower frame material 16. It is provided with a second metal fitting 43 arranged on the lower surface side of the above.

The orthogonal holding metal fitting 42 is bent at a right angle from the rectangular flat plate portion 42a, the pair of first engaging portions 42b and 42c bent upward from the flat plate portion 42a, and downward from the flat plate portion 42a. It has a pair of second engaging portions 42d and 42e. The flat plate portion 42a is arranged between the upper frame member 11 and the lower frame member 16. Further, a hole 42h through which the bolt 44 can be inserted is provided in the center of the flat plate portion 42a.

The first engaging portions 42b and 42c are provided in a state of being erected from a pair of opposite sides of the flat plate portion 42a along the side surface of the upper frame member 11. These first engaging portions 42b and 42c are erected from the flat plate portion 42a at intervals equal to or slightly larger than the width dimension of the upper frame member 11 and in a state parallel to each other. Therefore, as shown in FIG. 4, when the lower surface of the upper frame member 11 is arranged so as to come into contact with the upper surface side of the flat plate portion 42a, the first engaging portions 42b and 42c are arranged on the side surface (shape) of the upper frame member 11. Join with the steel flange part).

Further, the second engaging portions 42d and 42e have the first engaging portions 42b and 42c so as to follow the side surface of the lower frame member 16 from a pair of sides different from the sides provided with the first engaging portions 42b and 42c. It is installed in a state of standing on the opposite side. These second engaging portions 42d and 42e are erected from the flat plate portion 42a at intervals equal to or slightly larger than the width dimension of the lower frame member 16 and in a state parallel to each other. Therefore, as shown in FIG. 4, when the upper surface of the lower frame member 16 is arranged so as to come into contact with the lower surface side of the flat plate portion 42a, the second engaging portions 42d and 42e are arranged on the side surface (shape) of the lower frame member 16. Join with the steel flange part). In the present embodiment, since the width dimensions of the upper frame material 11 and the lower frame material 16 are equal to each other, the flat plate portion 42a becomes a square, the distance between the first engaging portions 42b and 42c and the second engaging portion 42d, The intervals of 42e are equal to each other.

The first metal fitting 41 has a rectangular flat plate portion 41a and a pair of engaging portions 41b and 41c bent downward at a right angle from the flat plate portion 41a. The flat plate portion 41a is substantially square and is arranged in a state of being in contact with the upper surface of the upper frame member 11. Further, a hole 41h through which the bolt 44 can be inserted is provided in the center of the flat plate portion 41a.

The engaging portions 41b and 41c are provided in a state of being erected downward from a pair of opposite sides of the flat plate portion 41a along the side surface of the upper frame member 11. These engaging portions 41b and 41c are erected downward from the flat plate portion 41a at intervals equal to or slightly larger than the width dimension of the upper frame member 11 and in a state parallel to each other. Therefore, as shown in FIG. 4, when the upper surface of the upper frame member 11 is arranged so as to come into contact with the lower surface side of the flat plate portion 41a, the engaging portions 41b and 41c are arranged on the side surface (shaped steel) of the upper frame member 11. Join with the flange part).

The second metal fitting 43 also has the same configuration as the first metal fitting 41. More specifically, the second metal fitting 43 has a rectangular flat plate portion 43a and a pair of engaging portions 43b and 43c bent upward at right angles from the flat plate portion 43a. The flat plate portion 43a is substantially square and is arranged in a state of being in contact with the lower surface of the lower frame member 16. Further, a hole 43h through which the bolt 44 can be inserted is provided in the center of the flat plate portion 43a.

The engaging portions 43b and 43c are provided in a state of being erected upward from a pair of opposite sides of the flat plate portion 43a along the side surface of the lower frame member 16. These engaging portions 43b and 43c are erected upward from the flat plate portion 43a at intervals equal to or slightly larger than the width dimension of the lower frame member 16 and in a state parallel to each other. Therefore, as shown in FIG. 4, when the lower surface of the lower frame member 16 is arranged so as to come into contact with the upper surface side of the flat plate portion 43a, the engaging portions 43b and 43c are arranged on the side surface of the lower frame member 16 (of the shaped steel). Join with the flange part).

When the first metal fitting 41, the orthogonal holding metal fitting 42 and the second metal fitting 43 are arranged with respect to the upper frame material 11 and the lower frame material 16 as described above, the three holes 41h, 42h and 43h are coaxially positioned. Moreover, it matches the position of the slit 18 provided in each of the frame materials 11 and 16. In this state, when the bolt 44 is inserted through, for example, the hole 41h provided in the first metal fitting 41, the tip of the bolt 44 is in a state of protruding downward from the hole 43h provided in the second metal fitting 43. By attaching a nut 45 to the tip of the protruding bolt 44 and tightening the nut 45, the orthogonal connecting member 20 connects and fixes the upper frame member 11 and the lower frame member 16 in a state of being orthogonal to each other. In particular, the first engaging portions 42b and 42c of the orthogonal holding metal fitting 42 are fixed to the side surface of the upper frame member 11, and the second engaging portions 42d and 42e are joined to the side surface of the lower frame member 16. Therefore, the upper frame material 11 and the lower frame material 16 do not rotate about the bolt 44, and the orthogonal state is maintained satisfactorily.

Further, when the tightened state of the bolt 44 and the nut 45 is loosened, the attachment position of the orthogonal connecting member 20 can be relatively moved along the slit 18 of the upper frame material 11, and the lower frame material can be moved relatively. It is also possible to move it relatively along the slit 18 of 16. Therefore, by loosening the bolt 44 and the nut, the orthogonal connecting member 20 can adjust the position where the upper frame member 11 and the lower frame member 16 intersect. This makes it possible to appropriately adjust the size of the rectangular frame by the frame frame body 2. Therefore, it is possible to adjust the spacing between the upper frame members 11, 12, 13, and 14, and it is also possible to adjust the spacing between the lower frame members 15, 16. If the crossing position between the upper frame material 11 and the lower frame material 16 is determined, the bolt 44 and the nut 45 are fastened at the crossing position so that the upper frame material 11 and the lower frame material 16 are orthogonal to each other. It can be fixed in a state of being.

The frame frame body 2 is configured as described above. The outer size of the frame body 2 is designed in advance according to the size of the air conditioner 100 when the blowout unit 120 and the intake unit 130 are assembled to the air conditioner main body 110. For example, the width dimension (dimension in the X direction) of the frame body 2 is designed to be substantially the same as the width dimension of the air conditioner 100. That is, in the present embodiment, the first to third support members 3, 4, and 5 for supporting the air conditioner main body 110, the blowout unit 120, and the intake unit 130 are attached to the lower frame members 15, 16, and thus the lower stage. The distance between the frame members 15 and 16 is designed to be substantially the same as the width dimension of the air conditioner 100. Further, the dimensions of the frame body 2 in the length direction (dimensions in the Y direction) can be appropriately designed. For example, the dimension of the frame body 2 in the length direction may be designed to be longer than the length of the air conditioner main body 110 in which the blowout unit 120 and the intake unit 130 are assembled. It may be designed to the extent.

Next, the first support member 3, the second support member 4, and the third support member 5 attached to the lower frame members 15 and 16 will be described. FIG. 5 is a diagram showing a configuration example of the first support member 3, the second support member 4, and the third support member 5. First, the first support member 3 will be described with reference to FIG. The first support member 3 includes a fixing member 21 and a support bolt 22. The fixing member 21 is composed of a first metal fitting 41, a second metal fitting 43, and a nut 45 used in the above-mentioned orthogonal connecting member 20. The support bolt 22 has a male screw portion having a predetermined length, and the head is provided at the upper end of the male screw portion. The male screw portion of the support bolt 22 is formed to have a length sufficient for attachment to the connecting portion 113 provided on the side surface of the air conditioner main body 110.

In such a first support member 3, the first metal fitting 41 is arranged on the upper surface of the lower frame material 16, and the second metal fitting 43 is arranged on the lower surface of the lower frame material 16. Then, the support bolt 22 is inserted into the hole 41h provided in the flat plate portion 41a of the first metal fitting 41, and the second metal fitting 43 arranged on the lower surface of the lower frame material 16 via the slit 18 of the lower frame material 16. The nut 45 is attached to the tip of the support bolt 22 protruding from the hole 43h provided in the flat plate portion 43a of the above. The nut 45 is fastened to the lower surface of the second metal fitting 43, so that the first support member 3 is fixed to the lower frame member 16.

The first support member 3 configured as described above can change the mounting position with respect to the lower frame member 16 by loosening the nut 45 that is fastened to the lower surface of the second metal fitting 43. That is, when the nut 45 is loosened, the first support member 3 can move along the slit 18 of the lower frame member 16, so that the position can be easily adjusted. Therefore, the position of the first support member 3 can be adjusted so as to match the position of the connecting portion 113 provided on the side surface of the air conditioner main body 110. Then, once the position of the first support member 3 is determined, the first support member 3 can be fixed to the lower frame member 16 by tightening the nut 45. Although FIG. 5 illustrates the first support member 3 fixed to the lower frame member 16, the same applies to the first support member 3 fixed to the lower frame member 15.

Next, the second support member 4 includes a fixing member 23 and a support bolt 24. The fixing member 23 and the support bolt 24 in the second support member 4 have the same configuration as the fixing member 21 and the support bolt 22 of the first support member 3. However, the male screw portion of the support bolt 24 may have a different length from the male screw portion of the support bolt 22.

Further, the third support member 5 includes a fixing member 25 and a support bolt 26. The fixing member 25 and the support bolt 26 in the third support member 5 have the same configuration as the fixing member 21 and the support bolt 22 of the first support member 3. However, the male screw portion of the support bolt 26 may have a different length from the male screw portion of the support bolt 22.

Next, the connecting member 6 for connecting the hanging member 9 will be described. As described above, the connecting member 6 is attached to both ends of the upper frame members 11 and 12, for example. As shown in FIG. 1, the connecting member 6 is composed of, for example, anti-vibration hangers 27 attached to the upper frame members 11 and 12. The anti-vibration hanger 27 is a metal fitting that connects the frame frame 2 and the suspension member 9 so as not to transmit the vibration generated during the operation of the air conditioner 100 to the suspension member 9, and the lower end of the box-shaped frame is The lower end portion of the suspension member 9 is connected to an elastic member 28 such as a spring spring provided inside the box-shaped frame body, which is fixed to the upper frame members 11 and 12. That is, in the anti-vibration hanger 27, the elastic member 28 absorbs the vibration so that the vibration of the air conditioner 100 is not transmitted to the suspension member 9. Such a connecting member 6 can be moved along the slits 18 of the upper frame members 11 and 12, and the attachment position of the upper frame members 11 and 12 in the longitudinal direction can be adjusted. Therefore, the suspension member 9 can be connected to any position of the upper frame members 11 and 12. In this embodiment, the case where the connecting member 6 is composed of the anti-vibration hanger 27 is illustrated, but the present invention is not limited to this. That is, the connecting member 6 may have any structure as long as the hanging member 9 such as a hanging bolt can be connected to the upper frame members 11 and 12.

FIG. 6 is a diagram showing a construction procedure of the air conditioner 100 using the gantry 1 in the present embodiment. First, as shown in FIG. 6A, as a first step, the operator sets the air conditioner main body 110 with respect to the support bolts 22 of the first support member 3 extending downward from the lower frame members 15 and 16 of the gantry 1. The connecting portion 113 of is fixed. For example, the tip end portion (lower end portion) of the support bolt 22 is inserted into the U-shaped engaging portion of the connecting portion 113, and the support bolt 22 is installed in a state of supporting the connecting portion 113 using a nut. At this time, two nuts are attached to the support bolts 22, and the two nuts are fastened so as to sandwich the upper and lower parts of the connecting portion 113 so that the air conditioner main body 110 is attached to the lower side of the lower frame members 15 and 16. It is preferable to fix the position at a predetermined height.

When the air conditioner main body 110 is attached to the gantry 1, the operator then performs the work of the second step. In this second step, first, as shown in FIG. 6A, the blowout unit 120 and the intake unit 130 are supported by the second support member 4 and the third support member 5 attached to the lower frame members 15 and 16, respectively. Attach to bolts 24 and 26. That is, the support bolts 24 and 26 are inserted into the holes 141 of the mounting members 140 attached to the blowout unit 120 and the intake unit 130, respectively, and the nuts are attached to the support bolts 24 and 26 to attach the support bolts 24 and 26. Is installed in a state of supporting each of the blowout unit 120 and the intake unit 130. Also in this case, it is preferable to attach two nuts to the support bolts 24 and 26 and fasten them so as to sandwich the upper and lower parts of the mounting member 140 with the two nuts.

Further, when the blowout unit 120 and the intake unit 130 are attached to the support bolts 24 and 26, the nut 45 attached to the lower surface of the second metal fitting 43 of the second support member 4 and the third support member 5 is loosened. It is preferable to keep it. As a result, the blowout unit 120 and the intake unit 130 can be attached to the support bolts 24 and 26, respectively, while adjusting the positions of the second support member 4 and the third support member 5. Further, by loosening the nut 45, after attaching the blowout unit 120 and the intake unit 130 to the support bolts 24 and 26, each of the blowout unit 120 and the intake unit 130 is moved toward the air conditioner main body 110. Will be able to.

Next, as shown in FIG. 6A, the operator pushes the blowout unit 120 in the direction of the arrow F1 to insert the connection portion 121 of the blowout unit 120 into the inside of the blowout portion 111 and attach it. Further, the intake unit 130 is mounted by inserting the connection portion 131 of the intake unit 130 into the inside of the intake portion 112 by pushing in the direction of the arrow F2. As a result, the air conditioner 100 is in a state as shown in FIG. 6 (b). However, in the state shown in FIG. 6B, since the nuts 45 of the second support member 4 and the third support member 5 that support the blowout unit 120 and the intake unit 130 are loosened, the blowout unit 120 and The intake unit 130 is not fixed to the air conditioner main body 110.

In that state, the operator performs a work of driving a screw around the blowout portion 111 as needed. As a result, the blowout portion 111 of the air conditioner main body 110 and the connection portion 121 of the blowout unit 120 can be connected and reinforced, and the blowout unit 120 is air-conditioned by the wind pressure when the air conditioner main body 110 is operated. It is possible to prevent the air conditioner from being separated from the main body 110. Since the operator can perform the screw driving work on the floor surface, the screw can be driven efficiently. However, in the gantry 1 of the present embodiment, since the blowout unit 120 can be fixed in a state where the second support member 4 presses the blowout unit 120 against the air conditioner main body 110, screws are attached to the periphery of the blowout portion 111. The work of typing in is not essential.

Further, when the screw driving operation is performed, the operator then performs the operation of winding the heat insulating material around the blowout portion 111. This prevents dew condensation from forming around the blowout portion 111.

Further, when the screws are not driven around the blowout portion 111, the heat insulating material may be arranged in advance on the inside of the connection portion 121 of the blowout unit 120. That is, in order to prevent dew condensation from occurring on the inner surface side of the connecting portion 121, the heat insulating material is arranged in close contact with the inner surface of the connecting portion 121. By arranging the heat insulating material inside the connecting portion 121 in advance in this way, it is not necessary to wind the heat insulating material on the outside of the blowing portion 111 after mounting the blowout unit 120 on the air conditioner main body 110. is there. However, when the screw is driven into the outer peripheral surface of the blowout portion 111, if the heat insulating material is arranged inside the connecting portion 121, the heat insulating material is floated from the inner surface of the connecting portion 121 by the screw. There is a possibility that condensation will form on that part. Therefore, when the screw driving work is performed, the heat insulating material is not arranged in advance inside the connecting portion 121 of the blowing unit 120, but after the screw driving is completed, the heat insulating material is applied to the outer peripheral surface of the blowing portion 111. It is preferable to carry out the work of wrapping the heat insulating material.

After that, as shown in FIG. 6C, the operator attaches the nut 45 mounted on the lower surface of the second metal fitting 43 of the second support member 4 and the third support member 5 to the lower surface of the second metal fitting 43. The second support member 4 and the third support member 5 are fixed to the lower frame members 15 and 16 by tightening.

When the screw is not driven into the outer peripheral surface of the blowout portion 111 of the air conditioner main body 110, the operator preferably tightens the nut 45 with the blowout unit 120 pressed against the air conditioner main body 110. .. As a result, even when the air conditioner main body 110 is operated, the air conditioner main body 110 and the blowout unit 120 are blown out so that the blowout unit 120 does not separate from the air conditioner main body 110 or air leakage occurs. The unit 120 can be integrally assembled. If the screw has already been driven into the outer peripheral surface of the blowout portion 111 of the air conditioner main body 110, the operator may perform the tightening work of the nut 45 in that state.

Further, when tightening the nut 45 of the third support member 5, it is preferable that the operator tightens the nut 45 with the intake unit 130 pressed against the air conditioner main body 110. As a result, the air conditioner main body 110 and the intake unit 130 can be integrally assembled so that the intake unit 130 does not separate from the air conditioner main body 110 or air leakage occurs.

This completes the work of the second step. In the above description, an example in which the nut 45 is tightened after the screw is driven into the outer peripheral surface of the blowout portion 111 of the air conditioner main body 110 has been described, but the order may be changed. That is, by tightening the nut 45 in a state where each of the blowout unit 120 and the intake unit 130 is pressed against the air conditioner main body 110, the second support member 4 and the third support member 5 are attached to the lower frame members 15 and 16. After fixing, the work of driving screws and the work of involving the heat insulating material may be performed on the outer peripheral surface of the blowout portion 111 of the air conditioner main body 110.

When the work of the second step is completed, the gantry 1 is in a state where the air conditioner 100 in which the air conditioner main body 110, the blowout unit 120, and the intake unit 130 are integrally assembled is supported by the frame frame 2. .. Then, the worker performs the work of the third step.

In the third step, as shown in FIG. 7, the operator installs the air conditioner 100 supported by the frame body 2 on the elevator 181 of the elevator 180, and installs the air conditioner 100 in a ceiling structure such as a ceiling slab. Work to raise it to a position near. At this time, each of the air conditioner main body 110, the blowout unit 120, and the intake unit 130 is supported by the frame body 2. Therefore, for example, as shown in FIG. 7, even if the operator raises the elevator 181 with only the air conditioner main body 110 mounted on the elevator 181 of the elevator 180, the air conditioner main body 110 is blown out. The load of the blowout unit 120 and the intake unit 130 is not applied to the unit 111 and the intake unit 112, and the fragile blowout unit 111 and the intake unit 112 are not damaged. Therefore, the operator does not need to use a plurality of elevators to simultaneously and evenly lift each of the air conditioner main body 110, the blowout unit 120, and the intake unit 130, and uses one elevator 180. The integrated air conditioner 100 can be raised to a position near the ceiling structure. Therefore, by using the gantry 1 of the present embodiment, it is possible to improve the work efficiency of the third step of raising the air conditioner 100 to a position near the ceiling structure.

When the gantry 1 is lifted to a position near the ceiling structure while supporting the integrated air conditioner 100, the operator then, as a fourth step, attaches the suspension member 9 hanging from the ceiling structure to the frame frame body 2. The air conditioner 100 is installed in a suspended state from the ceiling structure by connecting to the connecting members 6 provided on the upper frame members 11 and 12.

FIG. 8 is a perspective view showing a state in which the suspension member 9 is connected to the gantry 1. FIG. 8 illustrates a case where the suspension member 9 is a suspension bolt. As shown in FIG. 8, when the suspension member 9 is connected to the connecting member 6 of the upper frame members 11 and 12, the gantry 1 is fixed in a state of being suspended by the suspension member 9. That is, the gantry 1 is fixed in a state where the air conditioner 100 is supported at a predetermined position in the ceiling space.

In the present embodiment, when the gantry 1 is installed in a state of being suspended from the ceiling structure, four suspension members 9 may be connected to the frame frame body 2. That is, when the worker performs the work at a high place in the fourth step, if the work of connecting the four suspension members 9 to the frame frame body 2 is performed, the air conditioner main body 110, the blowout unit 120, and the intake unit 130 can be connected. An air conditioner 100 in which each is integrated can be installed at a predetermined position in the ceiling space. Therefore, if the gantry 1 of the present embodiment is used, it is not necessary to attach suspension members such as suspension bolts to each of the air conditioner main body, the blowout unit, and the intake unit in the aerial work as in the conventional case. Since the number of hanging members to be attached can be reduced, there is an advantage that the efficiency of aerial work can be improved.

Further, since the number of suspension members 9 connected to the gantry 1 can be reduced, there is an advantage that the space above the blowout unit 120 and the intake unit 130 can be effectively utilized. FIG. 9 is a diagram showing an example of a state in which the air conditioner 100 is installed in the ceiling space. In the example shown in FIG. 9, the ceiling structure 200 is provided with a beam 210 made of H-shaped steel or the like. The beam 210 is located above the intake unit 130. Further, various pipes 220 are suspended in the ceiling structure 200. The pipe 220 is located above the blowout unit 120. Even in such a situation, the gantry 1 of the present embodiment supports the gantry 1 in a state of being suspended below the obstacle by installing the suspension member 9 at a position where there are no obstacles such as the beam 210 and the pipe 220. can do. Therefore, even if there are obstacles such as beams 210 and pipes 220 in the ceiling space where the blowout unit 120 and the intake unit 130 should be installed, the gantry 1 of the present embodiment blows out at a position below the obstacles. The unit and the intake unit can be installed in a suspended state, and the space above the blowout unit 120 and the intake unit 130 can be effectively utilized.

Further, when the gantry 1 of the present embodiment is used, even if the position of the suspension member 9 previously attached to the ceiling structure 200 is deviated from the position of the connecting portion 113 of the air conditioner main body 110, the suspension member 9 is suspended. The gantry 1 can be attached to the member 9. That is, in the gantry 1 of the present embodiment, the spacing between the upper frame members 11 and 12 can be adjusted as described above, and the suspension member 9 is connected to an arbitrary position in the longitudinal direction of the upper frame members 11 and 12. can do. Therefore, even if the position of the hanging member 9 hanging from the ceiling structure 200 is slightly deviated from the design position, the spacing between the upper frame members 11 and 12 is adjusted according to the position of the hanging member 9. At the same time, by adjusting the attachment position of the connecting member 6 with respect to the upper frame members 11 and 12, the frame frame 2 of the gantry 1 can be connected to such a hanging member 9. Therefore, the worker does not need to re-install the suspension member 9 in the ceiling structure 200 by using a post-construction anchor or the like, so that the work can proceed efficiently.

Further, the gantry 1 of the present embodiment can be used even when the air conditioner 100 is renewed. That is, when the air conditioner 100 is renewed, the gantry 1 is once lowered from the ceiling space onto the floor surface, and the air conditioner 100 supported by the frame body 2 is replaced with the new air conditioner 100. At this time, the air conditioner 100 newly installed with respect to the frame body 2 is generally smaller than the previous air conditioner 100. Therefore, the operator adjusts the spacing between the lower frame members 15 and 16 in the frame frame 2 so as to match the size (width dimension) of the new air conditioner 100, and adjusts the new air conditioner 100 to the frame frame. Install in 2.

FIG. 10 is a diagram showing an example of adjusting the gantry 1 at the time of updating. For example, it is assumed that the gantry 1 is in the state shown in FIG. 10A before the update of the air conditioner 100. That is, before the update, the intervals between the lower frame members 15 and 16 in the frame body 2 are set to be substantially the same as the size (X1) of the air conditioner 100 before the update. Then, when the air conditioner 100 is updated, assuming that the dimension of the new air conditioner 100 in the X direction is reduced to X2, the operator lowers the gantry 1 to the floor surface, and then FIG. As shown in b), the spacing between the lower frame members 15 and 16 is changed to fit the size (X2) of the new air conditioner 100. As a result, even if the size of the air conditioner 100 changes before and after the update, the new air conditioner 100 can be supported by using the same gantry 1.

Further, when adjusting the rectangular size of the frame body 2 at the time of updating, if the spacing between the upper frame members 11 and 12 and the mounting position of the connecting member 6 are not changed, the hanging member 9 used before the updating can be used. The frame 1 can be reused as it is and installed in the ceiling space again. Therefore, the gantry 1 of the present embodiment does not need to re-install the suspension member 9 in the ceiling structure 200 by using a post-construction anchor or the like even when the air conditioner 100 is renewed, and the renewal work is efficient. There is an advantage that it can be done.

As described above, the gantry 1 of the present embodiment can integrally assemble the air conditioner main body 110, the blowout unit 120, and the intake unit 130 in the floor work, and is excellent in work efficiency. Further, in the gantry 1 of the present embodiment, when the concealed air conditioner 100 is installed in a state of being suspended from the ceiling structure, the number of suspension members 9 can be reduced as compared with the conventional case, so that the work at a high place can be performed. There is also an advantage that the ceiling space can be effectively utilized as well as being able to efficiently perform the above. Further, since the position where the suspension member 9 is connected to the gantry 1 can be adjusted and the rectangular size of the frame frame 2 can be adjusted according to the size of the air conditioner 100, the ceiling structure 200 can be adjusted. It is possible to install the air conditioner 100 in the ceiling space by effectively utilizing the suspension member 9 installed in advance.

Although one embodiment of the present invention has been described above, the present invention is not limited to the one described in the above embodiment. That is, the present invention includes those to which various modifications are applied to those described in the above embodiment.

For example, in the above embodiment, an example in which the blowout unit 120 and the intake unit 130 are mainly attached to the air conditioner main body 110 has been described. However, the intake unit 130 is not particularly essential. That is, the air conditioner 100 may be such that at least the blowout unit 120 is attached to the air conditioner main body 110.
