Description

INDUSTRIAL APPLICABILITY The present invention is a positioning tool for an air conditioner indoor unit installation plate used when installing an air conditioner indoor unit on an indoor wall surface, and in particular, a pipe for passing drain and refrigerant pipes through the indoor wall in advance. The installation plate for the indoor unit of the air conditioner that positions the target installation plate while ensuring the horizontal state so that the hole is configured as an opening and the indoor unit is placed on the wall surface in a positional relationship that is consistent with the piping hole. It is about a positioning tool.

When mounting the indoor unit installation plate of this type of air conditioner on the wall surface of the room, it is usually positioned at a certain distance from the ceiling or the side wall surface in consideration of the size of the indoor unit installed through it. At the same time, after ensuring a horizontal state, it is attached to the wall surface, and on the wall surface, the piping holes for passing the drain and refrigerant pipes are positioned in a predetermined positional relationship with the installation plate. The work of drilling the piping hole at that position is to be performed.

The installation procedure of such an installation plate is in the middle of construction on the wall surface of many rooms of the same standard in a newly built apartment house at any stage (positioning of the installation plate, adjustment of horizontal state, opening of piping holes). It seems that it is not done in stages, but it is supposed to be done on the wall of a detached building after completion even if it is an existing or new construction.

In contrast to the installation procedure for installing the air conditioner on the finished wall surface of the existing building, in the case of a new building, the piping holes for passing the drain and refrigerant pipes. Can be installed in the middle of finishing the wall, and if so, a sleeve pipe is placed inside the wall to fit the opened hole and is passed through the inside of the sleeve pipe for the drain and the refrigerant gas. It is possible to sufficiently protect each pipe.

Furthermore, when a newly built building is a large-scale condominium, rooms of the same standard are often continuous, so the installation plate to be installed should be installed on the ceiling or side of the room, considering the size of the indoor unit. It is assumed that the pipes are positioned at a distance of more than necessary from the wall surface and are mounted according to the position, and the pipe holes are positioned on the premise of such a mounted installation plate, and the pipe holes are positioned. For example, if the dimensions from the ceiling or the side wall can be measured with a dedicated rod-shaped measure, conversely, the rod-shaped measure or the like should be used before the installation plate is attached. Therefore, there is an advantage that the positioning of the piping hole can be performed extremely easily.

As described above, especially in the case of a newly built apartment building, unlike the case of the above-mentioned non-building, it is possible to open the pipe hole in the wall surface first and arrange the sleeve pipe in the pipe hole. Yes, as described above, by doing so, the protection of the drain pipe and the refrigerant gas pipe through which the pipe is passed can be sufficiently protected. In addition, when a large number of rooms of the same standard are continuous, the piping holes should be opened prior to the installation of the installation plate as described above because it is efficient. Then, in this case, the procedure is to position the installation plate with reference to the piping hole configured in this way, attach it to the wall surface, and fix it.

On the other hand, in the conventional technique, as described above, even in the existing building or a new construction, after the wall is completed, an installation plate is attached to the wall surface, and then the piping hole is positioned with the installation plate as a reference. This is done, and a pipe hole is made in the wall surface according to the positioning.

Although the work procedure is different from the case of using the positioning tool for the indoor unit installation plate of the air conditioner of the present invention, only such an example can be found in the prior art, and this will be described slightly. More specifically than the above description. The work is usually performed by one worker, therefore, for example, by pressing the installation plate in a suitable position on the wall with one hand while holding the measure with the other hand. , Measure the distance from the ceiling to the upper side and the distance from the side wall surface to the side side, and move the installation plate up, down, left and right according to the measurement result to perform positioning, and then use the measure as a spirit level. After changing hands, this time, the leveling device is used to perform troublesome work such as adjusting the level of the installation plate.

Then, at that time, while holding the positional relationship and the horizontal state of the installation plate with one hand, a nail or a tapping bolt is used with the other hand through a fixing hole opened at an appropriate position of the installation plate. Alternatively, work such as screwing or driving a screw or the like into the wall surface is performed, and the installation plate is fixed to the wall surface.

After that, as described above, the piping hole is positioned in relation to the installation plate, and the hole is drilled accordingly. The above-mentioned positioning of the piping hole is usually performed by determining the direction of the target installation plate from a predetermined position and measuring the dimension from the predetermined position. The drilling work on the wall surface is performed by using an appropriate opening means. In this case, since the wall has been completed, it is difficult to install the sleeve pipe inside the pipe hole as described above.

As described above, the work of attaching the installation plate to the wall surface and the work of positioning the piping holes are troublesome and time-consuming, so that the installation plate itself has been proposed with various ingenuity. Since it is related to the present invention, some of it will be described.

Patent Document 1 constitutes a partially arcuate rolling element passage that is low near the central portion and gradually increases toward both left and right sides on the front surface of the installation plate main body, and rolls the rolling element in the left-right direction on the rolling element passage. When arranging it freely and arranging the installation plate body on the wall surface, the horizontal state is adjusted by adjusting the angle of the installation plate body so that the rolling element is located at the center of the rolling element passage. It is an installation plate for mounting an air conditioner.

The air conditioner mounting installation plate of Patent Document 1 has the advantage that it can be easily mounted horizontally on the wall surface, but the useless rolling element passage remains in front of the installation plate, and the installation plate After adjusting the horizontal state, there are inconveniences such as having a rolling element that becomes useless. At the same time, there is also the inconvenience that the rolling element for leveling the installation plate is easily lost. Further, since there is no means for positioning this installation plate on the wall surface, there is no choice but to measure the distance from the ceiling or the side wall surface to the upper side or the side side by using an appropriate measure or the like. Furthermore, since there is no means for finding the position of the piping hole through which each of the drain and refrigerant pipes is passed, there is the inconvenience that there is no choice but to measure using a measure or the like for that purpose.

Patent Document 2 is a wall-mounted air conditioner installation plate provided with a spirit level for measuring the level at an appropriate position on the front surface of the installation plate.

The installation plate of the wall-mounted air conditioner of Patent Document 2 has the advantage that it can be easily mounted horizontally on the wall surface, like the installation plate for mounting the air conditioner of Patent Document 1, but on the ceiling or side. Since there is no means to measure the distance from the wall surface to the upper side or the side side, it is necessary to measure and position it using a measure or the like. Further, since there is no means for finding the position of the piping hole through which each of the drain and refrigerant pipes is passed, there is an inconvenience that there is no choice but to measure using a measure or the like as in the case of Patent Document 1.

In Patent Document 3, the lower parts of both sides of the installation plate are cut out, and both sides are formed into hypotenuses that widen downward, and a mark for vertical positioning is added in the middle of the lower part to either the left or right side. When opening a piping hole, extend an extension line along the hypotenuse, which is the side side of the relevant side, and then extend the extension line from the mark parallel to the lower side of the installation plate in either the left or right direction. Then, it is an installation device of an air conditioner so that the axis of the piping hole can be found at the intersection of both extension lines.

In the installation device of the air conditioner of Patent Document 3, the position of the piping hole can be found as described above, but for that purpose, in order to draw an extension line extending along the hypotenuse and to draw a lower side from the mark. A ruler for drawing a line parallel to the line or a rod-shaped member equivalent thereto is required. Further, in order to position the installation plate itself on the wall surface, a measure or the like for measuring the dimensions of both or one of the upper side to the upper ceiling and the side side to the side wall surface is also required, if necessary. Furthermore, in order to ensure the horizontality of the positioned installation plate, it is also necessary to prepare a spirit level separately.

Patent Document 4 constitutes an installation plate on which an indoor unit is installed with a display unit for instructing the position of a piping hole to be opened on the lower right side or the left side thereof, and the display unit of the installation plate has the piping hole. It is an air conditioner in which a display auxiliary member for displaying a position is combined, and the display auxiliary member is a cover member for an inspection or work opening of the indoor unit, which is made of synthetic resin.

In the air conditioner of Patent Document 4, the opening position of the piping hole is such that the display auxiliary member, which is a cover member of the indoor unit, is attached to the display portion as described above, and the installation plate is specified on the wall surface. If it is attached to the position of, it can be found by the display of the display auxiliary member. However, for that purpose, the cover member of the indoor unit and the installation plate need to have a special configuration as described above so that they can be combined with each other. Further, when mounting the installation plate on the wall surface, it is necessary to separately prepare a spirit level or the like in order to ensure its horizontality, and prior to that, in order to position the installation plate on the wall surface, the ceiling above the upper side thereof. A measure or the like for measuring both or one of the dimensions from the side to the side wall surface is also required.

In the above, in any case, the mounting plate may be attached to the wall surface by supporting the mounting plate with one hand while performing the measurement or the like with the other hand, and various fixing means to the wall surface. It is an extremely difficult and troublesome work, but there is no proposal example of a technology to improve it at this time.

Further, the tip of the width securing ruler, which is the end on the side opposite to the hole indicating portion on the side close to the hole indicating portion, is bent at a right angle to form a contact piece portion, and the rear end of the width securing ruler is at a right angle. When the contact piece at the tip is pulled out to the pull-out limit, the ruler at the rear end is on the side of the rivet close to the hole indicator. It is configured so that it is locked to the rivet and further withdrawal of the corresponding contact part is restricted.
The withdrawal limit of the width securing ruler is that the dimensional reference line of the dimensional reference portion and the dimensional reference of the installation plate displayed on the overhanging portion of the installation tool on the side surface of the level of the positioning tool. It is arranged so as to coincide with the dimensional reference line of the portion and to coincide with the position of the side portion protruding to the corresponding side of the indoor unit attached to the installation plate.

According to the positioning tool for the indoor unit installation plate of the air conditioner according to the present invention 1, it is extremely effective especially when the air conditioner is installed in each room of a newly built large-scale apartment building. In the case of such an apartment house, many rooms of the same standard are often configured, which is particularly effective.

In this case, it is necessary to preliminarily configure piping holes for passing the drain and refrigerant pipes at appropriate positions on the appropriate walls of each room. It is appropriate that the pipe hole is provided with a sleeve pipe inside, and the drain pipe and the refrigerant pipe are sufficiently protected. For that purpose, it is appropriate to start the creation of this piping hole before the completion of the target apartment building, for example, when a waterproof sheet is put on the outer surface side of the wall. At this stage, a hole of the required size is made at an appropriate position, a sleeve pipe having a length substantially corresponding to the thickness of the wall is placed on the inner side of the wall, and this is fixed to a stud or the like. If the studs are in contact with the sleeve pipe, they are fixed to the studs with nails or screws, and if they are not in contact, a support material fixed to the studs or pillars is placed inside the wall. Fix the sleeve pipe.

After that, when the wall material is lined on the indoor side of the room, for example, a hole is made in the wall material from the open outside side. When applying the exterior material to the outside, make a hole in the exterior material from the inside, or mark the appropriate parts above and to the side of the outside in advance, and position from these marks to the outside. Make a hole in the exterior material. When the sleeve pipe is arranged so as to project slightly outward, the exterior material is attached after making a hole of a corresponding size in advance so as not to interfere with the sleeve pipe. In this way, the piping holes are configured in advance.

Of course, the positioning of the piping hole is performed on the premise that an installation plate for the indoor unit is installed after that and the indoor unit is appropriately installed on the installation plate.
The installation plate is usually configured to be smaller in width and height than that of the indoor unit to be installed. Therefore, the installation plate should be at least above it, at least for the dimensions of the portion protruding upward from the upper side of the installation plate of the indoor unit in the installed state, and for the work when installing the indoor unit on the installation plate. It is necessary to leave a gap between the ceiling and the ceiling by a dimension equal to or greater than the sum of the dimensions of the required space. Further, in each lateral direction, it is necessary to leave a gap between the indoor unit in the installed state and the side wall surface at least by the size of the portion protruding from the side surface of the installation plate. Also, referring to the installation manual, each gap should be sufficient beyond what is required by the manufacturer.

Therefore, the installation plate must be positioned above and in both lateral directions with a gap of the above dimensions in reference to the above instructions.
According to the desired installation position of the indoor unit, the mounting state of the installation plate is assumed on the corresponding part of the wall surface, but of course, at this time, the dimension between the upper ceiling and the wall surfaces on both sides is larger than the above required dimension. You have to make sure that there is. In this way, the piping holes are positioned according to the positional relationship with the virtual installation plate that simulates the mounting state.

Positioning of the piping hole is to the left or right by a certain dimension (for example, 100 mm) from the dimensional reference part marked on the lower right or lower left part according to the instructions written on the installation plate (or the instruction manual). It will be done so that the point of is the axis. In many cases, the dimensional reference unit is composed of a vertical reference line that serves as a measurement reference for a certain dimension, and a horizontal arrow indicating that the fixed dimension destination is the axis of the piping hole from the reference line. ing. Therefore, a point separated from the reference line by the certain dimension in the direction indicated by the arrow is the axis of the piping hole.

When using the positioning tool for the indoor unit installation plate of the air conditioner according to the present invention, the piping hole should be configured in advance at an appropriate position on an appropriate wall of each room, as described above. .. Therefore, the position of the piping hole must be determined before mounting the installation plate, not in the procedure determined by the positional relationship with the installation plate mounted on the wall surface.
Specifically, regarding the position of the virtual piping hole determined by the procedure described above, the dimension from the floor surface or the floor base surface to the axis of the virtual piping hole and the position corresponding to the wall surface or the wall surface on at least one side thereof. Measure the dimensions up to the axis in advance, and create a bar-shaped ruler that displays each dimension. Then, it is appropriate to perform positioning using this rod-shaped ruler. By doing so, by measuring the dimension from the floor surface or the floor base surface and the dimension from the wall surface on one side or the position corresponding to the wall surface on the target wall for each room of the apartment house, it is extremely possible to measure it with a rod-shaped ruler. It is possible to easily and directly position the axis of the piping hole. The configuration of the piping hole is as described above.

In the positioning tool for the indoor unit installation plate of the air conditioner according to the present invention 1, the installation plate is positioned in the reverse procedure to the conventional procedure based on the positions of the piping holes configured as described above.
When locating the piping hole on the lower right side of the installation plate, orient the positioning tool so that the hole indicator is located on the right side, and when locating the piping hole on the lower left side of the installation plate, position the piping hole. Orient the positioner so that the hole indicator is located on its left side. This may be done by flipping the positioning tool left and right as needed. Further, in either case, the hole pointer arranged on the hole indicator is in a protruding state toward the wall surface when the positioning tool is placed on the overhanging portion of the installation plate and magnetically fixed temporarily on the front surface thereof, as will be described later. Adjust the orientation by replacing or re-screwing so that it becomes.

After preparing as described above, first, the positioning tool is placed on the overhanging portion protruding in front of the lower end of the installation plate, and is attached to the level of the positioning tool as described above. Align the dimensional reference part with the dimensional reference part for positioning the piping hole displayed on the installation plate, and in this state, install the positioning tool with the magnet member arranged on the side surface of the level. Temporarily magnetically fix to the front of the upright part of the board.

Next, the installation plate is moved to the corresponding vicinity of the corresponding wall surface of the room, and the hole pointer arranged in the hole indicating portion of the positioning tool is applied to the lowermost part of the inner circumference of the piping hole constituting the wall. The back surface of the installation plate is brought into contact with the wall surface. While maintaining each of these contact states, the installation plate is adjusted to a horizontal state using the spirit level of the positioning tool.

After that, the installation plate so positioned and adjusted to a horizontal state is fixed to the wall surface by screwing or driving screws or nails into the wall through fixing holes opened in various places thereof. Also, due to the position of the studs behind it, if necessary, screw the tapping screw into the part where the fixing hole is not opened to ensure fixing. In this way, the mounting plate can be positioned on the wall surface, the horizontal state can be adjusted, and the mounting plate can be mounted extremely easily and speedily. The work can be completed in a short time of 1/5 or less as compared with the case where a general measure or a spirit level is used in the conventional general procedure. In addition, even an unskilled person can complete the work accurately and in a short time as well as a skilled person.

According to the positioning tool for the indoor unit installation plate of the air conditioner of the present invention 2, the installation plate is appropriately positioned on the wall surface in relation to the piping hole and adjusted to a horizontal state, and then the installation plate is placed. It can be easily held on the wall surface with one hand while holding it with the other hand.

More specifically, as described above, the installation plate is positioned and adjusted to a horizontal state, and while being held in that state with one hand, the installation plate is held with the other hand. Insert the temporary holding material into a large number of fixing holes opened in the center as close to the center as possible, and pierce the wall surface by pushing the head of the temporary holding material, for example, if it is a stud-like member, by hand. Thus, if this is a nail-shaped member, it can be lightly driven with a mallet or the like, and if it is a screw-shaped member, it can be screwed in with an electric screwdriver or the like to be easily temporarily held on the wall surface. Since the temporary holding material is magnetically held on the installation plate by a magnet member, it does not fall even if the hand is temporarily released because an electric screwdriver or the like is used, and the work is performed without any problem. be able to. When performing the above work, the temporary holding means may be magnetically held on the installation plate so that the temporary holding material can be inserted into the fixing hole in advance.

In this way, the installation plate is temporarily held, and after that, both hands can be released from the installation plate. Therefore, after that, both hands can be freely used, and the final fixing of the installation plate using a screw member or the like can be performed extremely easily and surely. This is as mentioned above. Further, the temporary holding means is a method according to each property after the main fixing, for example, if it is a stud-shaped member, the head thereof is grasped and pulled out, and the temporary holding means is easily removed in such a manner. be able to.

According to the positioning tool for the indoor unit installation plate of the air conditioner according to the third aspect of the present invention, when the positioning tool is placed on the overhanging portion at the lower end of the installation plate, the interference is narrower than the lower surface of the spirit level body. Since the avoiding portion is placed on the overhanging portion, it is not necessary to interfere with the reinforcing ribs or the like configured between the upright portion which is the main body of the installation plate and the overhanging portion. ..

According to the positioning tool for the indoor unit installation plate of the air conditioner of the present invention 4, there is a wall of the indoor unit to be installed on the installation plate close to the side where the width securing ruler is pulled out, and the indoor unit to be installed on the installation plate. Even when there is almost no margin between the corresponding side and the wall, when positioning the installation plate, the width securing ruler is pulled out to the withdrawal limit, and the outer end of the width securing ruler is pulled out. By positioning the installation plate so that the portion touches the surface of the wall or there is a slight gap between the outer end portion and the wall, the indoor unit can be reliably installed on the installation plate. Can be done.

As described above, the installation plate is positioned by abutting the hole pointer of the positioning tool, which is placed on the overhanging portion at the lowermost portion and temporarily fixed, against the lowermost portion of the inner circumference of the piping hole. If the installation plate is moved significantly in the lateral direction, the refrigerant and drain pipes cannot pass through the pipe holes, but if the displacement is small in the lateral direction, each pipe accepts it. There is no problem because it is flexible enough to be used. Since the piping hole should have been originally configured at an appropriate position and should have a slight displacement, if any, the above lateral displacement should be extremely small. Stay within the range where there is no problem.

Hereinafter, embodiments for carrying out the invention will be described in detail with reference to the accompanying drawings based on examples.

As shown in FIGS. 1 and 2, the positioning tool for the indoor unit installation plate of the air conditioner of this embodiment is a spirit level consisting of a spirit level main body 1 having a substantially quadrilateral cross section and a horizontally long spirit level 2 arranged therein. 3 and the dimensional reference lines (dimension reference portions) 4 and 4 displayed on both side surfaces of the spirit level main body 1 and the hole indicator portion provided with the hole indicator rod 5 arranged on the end side of the spirit level main body 1. 6 is basically composed of two magnet members 7, 7 ... Arranged on both side surfaces of the spirit level 1, and a tube body (interference avoidance portion and through hole) 8 arranged on the lower surface of the spirit level 1. Further, a temporary holding means 12 including a magnet member 10 having a holding hole 9 penetrating the front and back and a stud-shaped member (temporary holding material) 11 fixed in the holding hole 9 in an inserted state is provided therein. It is a combination.

As described above, as shown in FIGS. 1 (a) to 1 (d), the spirit level 3 has a substantially quadrilateral and horizontally long spirit level main body 1 and a part thereof, and in this embodiment, substantially the central portion thereof. It is that of a general configuration including a horizontal measuring unit 2. The horizontal measuring unit 2 can be effectively used when the spirit level 1 is used upright (with the upper end surface facing up). The structure of the horizontal measuring unit 2 is the same as that of a general one, and is composed of a transparent container part having a normal structure and a liquid containing air bubbles enclosed in the container part, and in the horizontal state, the air bubbles are located in the central part. It is configured as follows.

As shown in FIGS. 1 (a), 5 and 6, the dimension reference lines 4 and 4 are directions orthogonal to these and the axis of the hole indicating rod 5 in the length direction of the leveler main body 1. The distance between the hole indicating line 5a that matches the disguised line drawn on both sides of the air conditioner is set to the dimensional reference line (dimensional reference part) 21 of the indoor unit installation plate 20 of the air conditioner and the dimensional reference line 20. On the other hand, it is drawn in accordance with the distance between the vertical line passing through the center of the piping hole 22 which should be in a predetermined positional relationship, and as shown in FIGS. 5 and 6, this positioning tool is mounted on the installation plate 20. When the dimensional reference lines 4 and 4 on both sides of the overhanging portion 23 projecting forward from the lower side are aligned with the dimensional reference lines 21 displayed on the installation plate 20, the positioning tool is used. The central axis of the piping hole 22 and the lowermost part of the inner circumference of the piping hole 22 to which the hole indicating rod 5 should be in contact are located on an extension line in the vertical direction of the hole indicating line 5a.

Therefore, the hole pointing rod 5 is positioned with the virtual extension line in the direction indicated by the hole pointing arrow (dimension reference portion) 24 of the mounting plate 20 in the state of being arranged on the installation plate 20 as described above. From the intersection of the hole indicator line 5a of the tool with the virtual extension line (the position of the central axis of the piping hole 22) to the position where the outer circumference of the hole pointer 5 is lowered until it comes into contact with the lowermost part of the inner circumference of the piping hole 22. It is for positioning.

As shown in FIGS. 1A to 1D, the hole indicating portion 6 is fixed in a direction orthogonal to the strip-shaped substrate 6a fixed on the lower surface of the spirit level main body 1 and the substrate 6a. It is composed of the provided nut member 6b and the hole pointing rod 5 screwed into the nut member 6b. The positional relationship of the hole indicator 6 in the spirit level body 1 is as described above, and the positional relationship of the hole pointer 5 is also as described above. Further, as can be understood from the above, the hole pointer 5 adopted in this embodiment is a bolt-shaped member. The hole pointer 5 is not limited to such a bolt-shaped member.

Further, on the upper surface of the spirit level main body 1, a magnetic plate 1a, which is a strip-shaped iron plate, is fixed at a position slightly left from the center in FIG. 1A, and the temporary holding means 12 is attached thereto. Can be magnetically attached by the magnetic action of the magnet member 10 and attached. The magnetic plate 1a has a stud insertion hole 1b opened in the center thereof, and when the temporary holding means 12 is magnetically attached to the magnetic plate 1a by a magnet member 10, the stud shape is formed. By inserting the member 11 into the stud insertion hole 1b, it can be done without any inconvenience.

In this embodiment, as described above, the case where the above installation plates 20 are installed in each room of a newly built large-scale apartment house, which is particularly effective, will be described as an example. In this case, a piping hole 22 for passing the drain and refrigerant pipes is configured in advance at an appropriate position on the appropriate wall surface of each room.

As the pipe hole 22, a sleeve pipe 22a is arranged on the inner circumference thereof so as to sufficiently protect each pipe for drain and refrigerant. Therefore, the pipe hole 22 starts to be created when a waterproof sheet is put on the outer surface side of the wall of the target apartment house. At this stage, a hole of the required size is drilled at an appropriate position, and a sleeve pipe 22a having a length corresponding to the thickness of the wall is placed on the inner side of the wall. If the studs inside the wall are in contact with the sleeve pipe 22a to be placed, the sleeve pipe 22a is fixed to the studs. This fixation is performed using a screw member or a nail in this embodiment. Depending on the room, the sleeve pipe 22a may not be in contact with the studs. In that case, a support member is arranged in the wall and the sleeve pipe 22a is fixed to the support member. Support members are fixed to studs and columns.

In this embodiment, the above-mentioned positioning of the piping hole 22 is performed by making a special ruler from a bar material and using the ruler. In this ruler, the bar is made to stand upright on the floor base of the room, a mark on the height side is drawn at a height position corresponding to the axis of the piping hole 22, and the bar is made horizontal. One end is brought into contact with the wall surface 28 on the side closer to the side, and a horizontal mark is drawn at a horizontal position corresponding to the axial center of the pipe hole 22 of the rod material.

The installation plate 20 is smaller in width and height than that of the indoor unit to be installed. Therefore, the installation plate 20 has at least the dimensions of the portion protruding upward from the upper side of the installation plate 20 of the indoor unit in the installed state and the dimensions necessary for the work of installing the indoor unit on the installation plate 20 above the installation plate 20. It is necessary to leave a gap between the ceiling 29 and the ceiling 29 by a dimension equal to or greater than the sum of the above, and in each lateral direction, at least the dimension of the part where the indoor unit in the installed state protrudes from the side of the installation plate 20. , It is necessary to leave a gap between the side wall surface 28 and the wall surface 28. The mark on the height side and the mark on the lateral direction of the ruler are set in consideration of the above and according to the desired installation position of the indoor unit.

The positioning of the piping hole 22 is, of course, performed on the premise that the installation plate 20 for the indoor unit is installed in accordance with the positioning of the piping hole 22 after the piping hole 22 is created. Further, if the indoor unit is subsequently installed on the installation plate 20, the installation position of the indoor unit will be as desired.

The special ruler is placed upright on one end of the floor base (the floor material has not been installed yet at this stage of construction), and the height position of the axis of the piping hole 22 is marked on the height side. Positioning is performed, and then one end of the dedicated ruler is brought into contact with the side wall surface 28 in a horizontal state, and the lateral position of the axis of the piping hole 22 is positioned by the mark on the lateral side. When a horizontal line is drawn according to the mark on the height side and a vertical line is drawn according to the mark on the horizontal direction side, the intersection of the horizontal line and the vertical line indicates the axis of the piping hole 22.

After that, using the intersection of the horizontal line and the vertical line as a mark, a hole having a diameter recommended as the piping hole 22, a hole of 70 mm in this embodiment, is made in the waterproof sheet, and the axis is centered on the axis of the hole. Sleeve pipes 22a having the same diameter are arranged so as to be aligned with each other, and the sleeve pipes 22a are screwed to the intersection column where the outer circumference is in contact. Since the outer circumference of the sleeve pipe 22a does not always come into contact with the studs, in that case, a support material is fixed to the studs or columns so that the side portion thereof comes into contact with the sleeve pipe 22a, and the sleeve pipe is attached to the support material. Screw it to 22a.

After that, when the wall material is lined on the indoor side of the wall, a hole is made in the wall material by various methods. For example, a hole is made in the wall material from the outside side of the opening. When applying the exterior material to the outside side, if the sleeve pipe 22a is slightly projected to the outside, the position is measured from the vertical and horizontal directions, and a hole corresponding to the corresponding part of the exterior material to be applied to the relevant part is made in advance.
