Description

  The present invention relates to a foundation block for an installation that constitutes a foundation for stably installing an installation such as a vending machine, a hot water supply facility, or an air conditioner outdoor unit installed outdoors on the ground.

  In the past, installations such as large-sized electric water heaters installed outdoors have been usually performed by placing concrete on the site and creating a foundation. When building a foundation by placing concrete at such a site, it takes several days for the foundation work and curing of the cast concrete, and about one day for the installation work of the installation. Cost. Therefore, there has been a problem that these installations cannot be installed quickly.

  Therefore, in recent years, the foundation for these installations has been constructed using precast concrete blocks. The following Patent Documents 1 to 3 propose this type of technology.

  Patent document 1 is related with the foundation block for water heater installation, and its construction method.

  The former block is a basic block for water heater installation in which an upper prefabricated block and a lower prefabricated block divided into at least two parts are stacked in a direction in which the joint surfaces are orthogonal to each other, and the upper and lower prefabricated blocks are joined and integrated with bolts. In the base block for installing the water heater, in the central part of the upper prefabricated block and the lower prefabricated block, a through hole for taking out the ground wire and the electric pipe is formed, and the through hole is further connected to the ground wire and the electric pipe. It may be configured to be fitted and closed with a lid having a through hole for use.

  In the latter construction method, a hole slightly larger than the outer shape of the lower prefabricated block is excavated, a ground wire and an electric pipe are laid in the center of the hole, and then at least one block divided into two at the bottom is placed. A lower prefabricated block is provided by disposing the other block on the side surface, and the upper prefabricated block at least divided into two at the upper surface of the lower prefabricated block is perpendicular to the joint surface of the lower prefabricated block. After the bolts are screwed into the bolt holes drilled in the upper and lower prefabricated blocks and joined and integrated, the lid is fitted into the through hole at the center of the upper and lower prefabricated blocks and then applied. It is a construction method of the foundation block for water heater installation.

  The basic block for water heater installation and its construction method of Patent Document 1 are as described above. Therefore, according to these, the upper and lower prefabricated blocks are brought to the site, and at the predetermined installation position, the above procedure is performed. The foundation for water heater installation can be constructed easily and speedily. Since there is no need for concrete curing, there is an advantage that a water heater can be installed on the day when the foundation is constructed.

  However, in the foundation block for water heater installation and its construction method of Patent Document 1, the foundation constructed in any case does not include attachment means for installing the water heater. It is necessary to drill a hole for matching the target water heater using an electric drill or the like. Also, in the case of this technology, when it is necessary to replace the water heater due to a failure of the water heater, the mounting means must be broken and constructed in order to remove the installed water heater. Some foundations will be difficult to reuse for replaced water heaters. Therefore, in this case, the existing foundation is dismantled and removed to construct a new foundation.

  Patent Document 2 relates to an assembling-type foundation block, and in the assembling-type foundation block on which an electric water heater is placed, the assembling-type foundation block is composed of two upper blocks and two lower blocks. Each base block has an L shape, and the two base blocks for the lower part are combined in a rectangular shape, and the two base blocks for the upper part are rotated 90 degrees on top of each other so as to contact each other vertically. These are assembled base blocks that are combined in a rectangular shape so that the side surfaces do not overlap, and may be provided with a rectangular reinforcing material and a linear reinforcing material in those blocks, and in that case, the anchor bolt holes Also, it is made to be drilled inside the reinforcing material.

  Therefore, according to the assembly-type foundation block of Patent Document 2, it is possible to quickly and easily construct the foundation for installing the electric water heater, and it is possible to perform the installation of the electric water heater in almost one day. It appears to be. However, in the case of this assembling-type foundation block as well, as in the technique of Patent Document 1, the mounting means for the electric water heater is not arranged on the foundation beforehand. Need to drill. Naturally, it drills so as to correspond to the target electric water heater.

  Also, in the case of the technique of Patent Document 2, in the same way as that of Patent Document 1, when it is necessary to replace the water heater due to a failure of the water heater or the like, there is also an attachment means for removing the installed water heater. At the same time, it must be broken, and the constructed foundation will be difficult to use for a new water heater. Therefore, in this case, the existing foundation is still dismantled and a new foundation is constructed.

  Patent Document 3 relates to a base for an installation object, and includes a base part on which an installation object having a plurality of attachment parts is placed on a bottom part, an attachment groove provided along an upper surface of the base part, and the attachment A fixture for fixing the portion to the mounting groove of the base portion, and the base portion is an installation base having an internal space for filling a filler serving as a weight.

  In this installation base, the base portion has an upper lid and a lower dish that are divided into upper and lower parts, and the upper lid and the lower dish have an insertion hole through which an earth wire or an electric pipe of the installation object is inserted. The base portion may be made of resin, and the center of the figure formed by connecting adjacent mounting portions of the plurality of mounting portions with a line and the center of the base portion The water heater is fixed to the base portion so as to coincide with each other, and the mounting groove extends in the same direction as the direction from the center of the figure formed by connecting the mounting portions to each mounting portion. There is. In addition to this, a plurality of patterns have been proposed for the mounting groove.

  Therefore, according to the installation base of Patent Document 3, it is possible to quickly and easily construct a base that is a basis for installing an installation such as a water heater, and the water heater etc. can be constructed almost in a day. It seems that it is possible to carry out up to the installation of installations. In particular, since the base for an installation of Patent Document 3 includes a mounting groove and a fixing tool in the base portion, the installation base such as a water heater having a mounting means corresponding to the mounting groove in the lower portion is provided. In this case, it becomes possible to install more speedily and appropriately. In this case, even if the installation needs to be replaced due to a failure or the like, the base can be reused as long as it is replaced with the same model.

  However, in the installation object base of Patent Document 3, each of the attachment grooves of each pattern cannot cope with attachment means in a wide range of different modes. Therefore, it is necessary to prepare a plurality of mounting grooves of a relatively large number of patterns. In fact, a plurality of mounting grooves are prepared, and various patterns can be obtained by using any one of them. It is possible to correspond to an installation provided with the attachment means. In the technique of Patent Document 3, there is a problem in that a single pattern of mounting grooves cannot support a wide range of different types of mounting means.

Japanese Patent Laid-Open No. 11-50470 JP 2005-351010 A Japanese Patent Laid-Open No. 2005-240479

  The present invention relates to a foundation block for an assembly-type installation using a precast concrete block that can be constructed in a short time, and solves the problems of the prior art, particularly the problem of Patent Document 3, a vending machine, Highly versatile that can be installed regardless of the arrangement of legs and other coupling means for mounting outdoor installations such as hot water supply facilities or air-conditioning outdoor units as long as the number corresponds. The problem to be solved is to provide a foundation block for installed objects.

According to one aspect of the present invention, one or more adjustment blocks are embedded and held so as to be capable of rotation adjustment, and the same number of main body blocks having a circular holding space when viewed from above are arranged in the holding space of the main body block. It consists of the same number of holding spaces and circular adjustment blocks as viewed from above.
A base block for an installation, in which the adjustment block is provided with an attachment means for coupling to a lower coupling means of the target installation and a rail portion that holds the attachment means in a slidable manner in the radial direction of the adjustment block. It is.

  2 of the present invention is the basic block for an installation according to 1 of the present invention, wherein the holding space of the main body block is configured in a tapered shape, and the peripheral side of the adjusting block is configured in the same tapered shape. It is.

  According to a third aspect of the present invention, in the foundation block for an installation according to the first or second aspect of the present invention, the adjustment block is in a positional relationship that allows the adjustment block to be held in the holding space of the main body block, and each adjustment block is rotated. A positioning plate that is supported in a free state is attached, and each adjusting block is rotated by using the positioning plate, so that each mounting means can be positioned in the circumferential direction in each adjusting block. It is.

  According to a fourth aspect of the present invention, in the foundation block for an installation according to the third aspect of the present invention, a shaft hole is opened at a lower center of the adjustment block, a support shaft is erected on the positioning plate, and the adjustment block is connected to the shaft hole. The support shaft is inserted into the positioning plate so as to rotate on the positioning plate.

  According to the foundation block for installed objects of 1 of the present invention, a foundation for stably fixing an installed object such as a vending machine, a hot water supply facility, or an air conditioner outdoor unit installed on the ground can be easily formed in a short time. If the number of connecting means of these installations matches the number of attachment means of this foundation, the attachment means can be positioned over a wide range, so that most installations Positioning can be performed corresponding to the coupling means, and the mounting can be performed. Therefore, if several types of installation object base blocks having different numbers of attachment means or different installation object sizes are prepared, it is possible to freely support installation of installation objects in a great number of modes.

  Since the mounting means is slidably disposed on a rail portion provided in the adjustment block along the radial direction, it can be arranged at any position in the radial direction of the adjustment block by sliding it. Further, the adjustment block itself can be rotated by an arbitrary angle. The holding space of the main body block can freely rotate the adjusting block on its inner side or insert it in a state where it is rotated by an arbitrary angle. Therefore, the mounting means can be arranged at any position in the region corresponding to the upper surface of the adjustment block if it is slid as much as necessary along the rail part and the adjustment block is rotated by a necessary angle. Be free.

Moreover, according to the installation object basic block of the present invention, the whole is divided into one main body block and one or more adjustment blocks, which can be easily handled by one operator. The weight can be configured as much as possible. Therefore, the construction of the foundation for the installation can be easily performed by one worker. Alternatively, the work can be performed without using at least heavy machinery. Further, as described above, since the positioning of the mounting means can be performed without hitting or vibrating, there is no possibility of causing damage to the blocks constituting the foundation or adversely affecting the foundation strength.
Furthermore, according to the foundation block for an installation of 1 of the present invention, since the main body block and the adjustment block are combined after the installation is completed, it is possible to secure a sufficient weight and ground contact area as a whole. Therefore, it is possible to secure a sufficient resistance against the falling of the installation object.

  Moreover, according to the foundation block for installed objects of 1 of this invention, when the necessity for replacement | exchange etc. arises by the failure of the installed object etc., the installed object is removed and a new installed object is attached. Can be easily done. If the new installation has coupling means of the same mode of arrangement, it is of course easily replaceable, but even if it is not of the same mode, the number of coupling means is the same and the size is If it is not extremely different, it is possible to correspond to the position of the coupling means by adjusting the position of the attaching means, and it can be easily attached. Since the foundation can be reused in this way, the amount of waste generated can be reduced.

  According to the foundation block for an installation of 2 of the present invention, the adjustment block is arranged in the foundation installation area so as to correspond to the position of the holding space of the main body block, and the main body block is placed on the adjustment block from above. By arranging in this way, it can be easily inserted into the holding space. Further, in such a charged state, both the holding space and the peripheral side of the adjustment block are configured to have a tapered shape, so that the adjustment block has a strong upward pulling resistance.

According to the installation object foundation block of the present invention, by arranging the adjustment block together with the positioning plate in the foundation installation area, the arrangement of the adjustment block easily matches the arrangement of the holding space of the main body block. The positioning becomes extremely simple. Further, since the adjustment block is arranged so as to be able to rotate on the positioning plate, the attachment means is adjusted by combining the rotation operation of the necessary angle of the adjustment block with the necessary slide movement operation on the rail portion of the attachment means. It is possible to easily correspond to the arrangement of the coupling means of the installation object to be attached. As described above, after the positioning of the attachment means is completed, the holding space of the main body block and the adjustment block are made to correspond to each other above and below the adjustment block, and then the main body block is lowered. The adjustment block can be loaded and held in the holding space. This operation can be performed very easily because the adjustment block is properly positioned.
Further, by employing the positioning plate in this way, in addition to the above effects, in the installed state, the substantial ground contact area of the adjustment block can be expanded to the area of the positioning plate, so that sufficient resistance to subsidence is achieved. Power can be secured.

  According to the foundation block for an installation of 4 of the present invention, the adjustment block can be easily placed in the foundation installation area by inserting the support shaft standing at a predetermined position of the plate member into the shaft hole in the lower center of the adjustment block. It can be positioned accurately and can be arranged to rotate. Also in this case, it goes without saying that the sinking resistance of the adjustment block can be increased by arranging the positioning plate below the adjustment block in this way.

  DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the invention will be described in detail with reference to the drawings.

<First example>
As shown in FIGS. 1 and 2, the basic block for an installation of the first example of the embodiment includes a main body block 1 that holds three adjustment blocks 2, 2, 2 in holding spaces 11, 11, 11. The adjustment blocks 2, 2, 2 are circular adjustment blocks 2, 2, 2 as viewed from the plane arranged in the holding spaces 11, 11, 11 of the main body block 1. Is provided with anchor bolts (attachment means) 21, 21, 21 and rail portions 22 in which these are slidably arranged. Further, the adjustment blocks 2, 2, 2 are positioned thereon. A positioning plate 3 is attached.

  As shown in FIGS. 1-4, the said main body block 1 is comprised by the reinforced concrete in the shape of a substantially square board | plate material seeing from a plane in this 1st example. The main body block 1 has an isosceles triangle with a straight line connecting the centers of the L-shaped leg plates (joining means) 41, 41, 41 of other types of installations such as the water heater 4 in a positional relationship substantially corresponding to the arrangement. The holding spaces 11, 11, 11 are formed so as to penetrate vertically. Each holding space 11, 11, 11 is formed in a tapered shape as can be understood particularly in FIGS. 2 and 4.

  In the first example, the main body block 1 has a front side thereof (a side having a vertex formed by isosceles of an isosceles triangle formed by a line connecting the centers of the holding spaces 11, 11, 11). The two nut members 12 and 12 which are insert metal fittings are arranged in the embedding state in the side which becomes. Needless to say, the nut members 12, 12 open to the front side, and, for example, when the main body block 1 is carried into the installation area, an eyebolt is screwed into the nut members 12, 12. Operations such as suspending and moving the main body block 1 through the members 12, 12 and eyebolts are made possible.

  Furthermore, in the first example, two grips 13 and 13 are formed on the main body block 1 on two side portions adjacent to the side portion on which the nut members 12 and 12 are arranged. As shown in FIGS. 1 to 4, these grips 13, 13 are recesses formed in the lower part near both sides of each side part. When the main body block 1 is moved, the handle 13 is inserted and operated. Thus, the work can be performed while avoiding the danger of fingers being pinched between the main body block 1 and the underlying substrate.

  The adjusting block 2 is a member made of concrete that is circular as seen from the plane, as described above and shown in FIG. 1 and inserted into the holding space 11 of the main body block 1. Like the holding space 11, it is formed in a tapered shape. The size in the radial direction is set to such a degree that the holding space 11 can be inserted smoothly while eliminating backlash. The thickness is the same as that of the main body block 1.

  Further, the adjustment block 2 has a rail portion 22 in which an anchor bolt 21 is slidably arranged as shown in FIGS. 1, 5A, 5B and 6A, 6B. Is arranged. The rail portion 22 is a long member made of metal. In the first example, the rail portion 22 is arranged in the embedded state along the radial direction in the vicinity of the central portion of the adjustment block 2 in the thickness direction, and one end thereof is The adjustment block 2 is opened to the circumferential side, and the other end is extended to a position beyond the center of the adjustment block 2. As shown in FIGS. 5 (a), (b) to 7 (a), (b), the rail portion 22 is provided with a groove-shaped opening 222 that opens upward in the entire length direction. The groove-shaped opening 222 is a member, and is opened on the upper surface side through a groove-shaped opening 23 that is similarly opened in a groove shape at a corresponding portion of the adjustment block 2.

As shown in FIGS. 5B and 6A in particular, the rail portion 22 is a member provided with an enlarged locking portion 221 that enlarges the intermediate portion in the vertical direction to both sides when viewed from the end portion. .
The anchor bolt 21 is inserted at the lower end side into the rail portion 22 from the outer end side, and the upper side thereof at the groove-like opening 222 on the upper side of the rail portion 22 and the upper surface side of the adjustment block 2. The anchor bolt 21 is arranged so as to protrude to the upper surface side of the adjustment block 2 through the groove-shaped opening 23. As shown in FIGS. 6 (a) and 7 (b), the anchor bolt 21 is The lower flange portion 211 is slidably engaged with the enlarged engagement portion 221 of the rail portion 22 to ensure free movement of the adjustment block 2 in the radial direction while preventing the detachment.

  As shown in FIGS. 6 (a), 7 (b) and 8 (a) in particular, the anchor bolt 21 is disposed on the bolt member, the flange portion 211 disposed on the lower portion thereof, and the upper portion of the bolt member. It comprises a nut member 213 for fixing the L-shaped leg plate 41, two types of washers 212, and the like, and as shown in FIG. The portion 211 is slidably inserted and locked to the enlarged locking portion 221 of the rail portion 22. Needless to say, the bolt member of the anchor bolt 21 protrudes to the upper part of the adjustment block 2 through the groove-like opening 222 and the groove-type opening 23 at the upper part of the rail part 22. As described above, in this state, the anchor bolt 21 can freely move in the radial direction of the adjustment block 2 along the rail portion 22, and at the same time, the enlarged locking portion 221 and the flange portion 211. This is why it is prevented from coming off by the action of.

  Further, the lower centers of the adjustment blocks 2, 2, 2 are respectively shown in FIGS. 5 (a), (b), FIGS. 6 (a), (b) and FIGS. 7 (a), (b). A shaft hole 24 is formed so as to open to the lower portion, and the positioning plate 3 attached to the adjustment blocks 2, 2, 2 corresponds to the positional relationship of the holding spaces 11, 11, 11 of the main body block 1. Each of the support shafts 31 is erected so that the adjustment blocks 2, 2, 2 can be arranged in a positional relationship. As shown in FIG. 7 (b), it goes without saying that the support shaft 31 is inserted in the state in which the shaft holes 24 of the adjustment blocks 2, 2, and 2 are externally mounted thereon, and the adjustment block 2, 2 and 2 are positioned in a predetermined positional relationship, and at the same time, the adjustment blocks 2, 2 and 2 are held so as to be capable of rotating.

In the first example, the above positioning plate 3 can place the three adjustment blocks 2, 2, 2 to be positioned with a margin, but is a quadrilateral slightly smaller than the main body block 1. The metal plate material configured as above was adopted. In addition, the positioning plate 3 can employ various members that meet the purpose of the positioning plate 3, such as a reinforced concrete plate having an appropriate thickness.
The support shafts 31, 31, 31 are metal shafts that are erected and fixed at the predetermined positions of the positioning plate 3 that is a quadrilateral metal plate material.
In addition, the shaft hole 24 formed at the center of the lower portion of the adjustment block 2 is formed by embedding a metal pipe body in a corresponding portion at the lower portion of the adjustment block 2 in this first example. The inside diameter of the support shaft 31 can be inserted without rattling, and at the same time, the adjustment block 3 is rotated while the support shaft 31 is inserted and the adjustment block 2 is supported on the positioning plate 3. It is assumed that there is a margin that is possible.

  The L-shaped leg plate 41 is an example of a coupling means used for many installations such as the water heater 4 and the first example will be described using this example. The L-shaped leg plate 41 is depicted in a state separated from the installation object in the figure, but this is for convenience and is actually fixed to the lower part of the installation object. The L-shaped leg plate 41 is as described above, and a locking slit 411 that opens at the tip is formed in the horizontal portion at the lower end of the L-shaped leg plate 41 as shown in FIGS. 1, 6B, and 7A. The anchor bolt 21 that protrudes from the rail portion 22 is inserted into the locking slit 411 from the opening at the tip thereof, and two types of washers 212 arranged on the upper portion thereof are attached to the anchor bolt 21. The nut member 213 that is placed on the top and screwed to the anchor bolt 21 is tightened, and is shown in FIGS. 1, 2, 6 (a), (b) and 7 (a), (b). Thus, it can be fixed to the upper surface of the adjustment block 2.

Therefore, according to the foundation block for installed objects of the first example, it is an installed object such as a vending machine, a hot water supply facility or an air-conditioning outdoor unit installed outdoors, and includes three L-shaped leg plates 41 as coupling means. It is possible to easily install a foundation for stably fixing the installation type of the installation on the ground in a short time.
As will be described later, with respect to an installation having one, two, or four or more L-shaped leg plates 41, 41..., A foundation block for installation having a corresponding number of the adjustment blocks 2 is configured. Needless to say, this is possible. Also, other modes described later can be used.

  In the first example, as described above, the installation object having the L-shaped leg plates 41, 41, 41 which are the three coupling means is an object, but if so, the anchor bolt 21, which is the attachment means, 21 and 21 respectively rotate the adjustment blocks 2, 2, 2 on which they are arranged by a necessary angle, and slide the rail portions 22, 22, 22 in a necessary direction as necessary. Positioning can be performed in any region corresponding to the upper surface occupied by the adjustment blocks 2, 2, 2. Therefore, positioning can be performed in accordance with the arrangement of the L-shaped leg plates 41, 41, 41 which are the coupling means of most installation objects, and the attachment can be performed.

  In addition, according to the foundation block for installed objects of the first example, when the installed object needs to be replaced due to a failure of the installed object, etc., the installed object is removed and a new installed object is attached. Can be easily done. When the new installation has the L-shaped leg plates 41, 41, 41 having the same arrangement, it can be easily replaced. However, even if the arrangement is not the same arrangement, the anchor bolts 21, 21 are easily replaced. If the number of coupling means is the same and the size is not extremely different, the position of the anchor bolts 21, 21, 21 can be adjusted by adjusting the position of the anchor bolts 21, 21 and 21. It can correspond to the position and can be easily attached. Therefore, it is possible to reuse the foundation when exchanging the installations, so that an increase in waste can be avoided.

The method of creating the foundation for the installation will be described specifically.
A ground is formed in the installation area of the installation object. If it is a flat area made of concrete, special preparation may not be necessary, but it is usually appropriate to dig a little in the installation area, place crushed stones in it, and slightly strengthen the groundwork. is there. On the crushed stone, for example, a mixture of air-kneaded sand and cement is disposed to facilitate horizontal adjustment, and then the positioning plate 3 is disposed. Needless to say, the positioning plate 3 is an installed object, and the hot water heater 4 is assumed here. Naturally, it adjusts and arrange | positions horizontally on the mixture of the said sand and cement. In addition, the mixture of the cement and sand will be cured by receiving moisture, rainwater, etc. in the soil.

  Thereafter, the three adjusting blocks 2, 2, 2 are positioned on the positioning plate 3. As shown in FIGS. 7 (a) and 7 (b), this positioning arrangement is performed by the support shafts 31, 31, 31 standing on the upper surface of the positioning plate 3 and the lower portions of the adjusting blocks 2, 2, 2. This can be done easily and accurately by extrapolating the central shaft hole 24.

  Next, the anchor bolts 21, 21, 21 as the attachment means are positioned so as to correspond to the arrangement of the L-shaped leg plates 41, 41, 41 that are the connection means of the water heater 4 that is the installation object. As shown in FIG. 6 (b) and FIG. 7 (a), the adjustment blocks 2, 2, and 2 arranged in this manner are rotated by a necessary angle and the anchor bolts 21, 21, and 21 are rotated. This can be performed by sliding the rail portions 22, 22, and 22 by a necessary distance. Either of these two operations may be performed first. If these operations are performed on the three adjustment blocks 2, 2, and 2, and the anchor bolts 21, 21, and 21 arranged on the respective adjustment blocks are positioned, the positioning of the anchor bolts 21, 21, and 21 is completed.

  After the positioning of the anchor bolts 21, 21, 21 is completed in this way, the main body block 1 is set on the adjustment blocks 2, 2, 2 as shown in FIGS. 8 (a) and 8 (b). As shown in the figure, the holding spaces 11, 11, 11 and the adjusting blocks 2, 2, 2 are made to correspond vertically, and then the main body block 1 is lowered from above to hold the holding spaces 11, The adjustment blocks 2, 2, 2 may be put on the exterior at 11, 11.

  In addition, in the above, this foundation block for installations is divided into one main body block 1 and three adjustment blocks 2, 2, 2 and is lighter. One worker can handle it. Further, with respect to the main body block 1, nut members 12 and 12 which are inserts are arranged on one side, so that an eyebolt can be screwed into these and can be suspended and moved through the eyebolt. As shown in 8 (a) and 8 (b), when placing it in the installation area, etc., it is possible to injure by putting the hand between the handles 13 and 13 which are concave portions, and pinching the finger between the ground. It is possible to avoid the fear of doing.

  After constructing the foundation in this way and positioning the anchor bolts 21, 21, 21, the water heater 4 to be attached is moved onto the foundation, and the L-shaped leg plates 41, 41, 41 are moved to the anchor bolts. Lowers after corresponding to 21, 21, 21. Since the anchor bolts 21, 21, and 21 are positioned corresponding to the positional relationship between the L-shaped leg plates 41, 41, and 41, the L-shaped leg plates 41, 41, and 41 are easily brought close to them. The adjustment blocks 2, 2, 2 can be lowered. If the orientation of the L-shaped leg plates 41, 41, 41 is set in a certain direction, the adjustment slit 411 that opens at the tip of the horizontal portion is adjusted to the direction that opens toward the anchor bolts 21, 21, 21, respectively. 2, 2, and 2, and then the water heater 4 is slid to the anchor bolts 21, 21, 21 side, so that the anchor bolts 21, 21 and 21 can be made to enter easily.

  Thereafter, when the two types of washers 212 are respectively lowered on the horizontal portions of the L-shaped leg plates 41, 41, 41, and the nut member 213 is tightened from above, the L-shaped leg plates 41, 41, 41, as shown in FIG.
