Description

  The present invention relates to a support base structure that supports the above-described object when the object is installed.

  When a unit such as an electric water heater or a gas water heater is installed on the ground surface portion, the unit is heavy, and thus a part of the unit may be buried under the ground surface. Thus, in order to suppress that a part of unit is buried, the foundation block which can mount and support the said unit is installed. The unit is placed on the foundation block and installed at the installation location.

  The basic block, which is a conventional technique, is a base having a two-layer structure that includes a lower layer portion and an upper layer portion, and is configured by stacking the upper layer portion above the lower layer portion. The lower layer part and the upper layer part are formed by abutting and joining two prefabricated blocks together. The lower layer part and the upper layer part are laminated so that the bonding surfaces are orthogonal to each other. Thus, a basic block can be easily formed only by laminating an upper layer portion and a lower layer portion formed by abutting two prefabricated blocks. (For example, see Patent Document 1)

Japanese Patent No. 3079422 (FIG. 1, pages 2 to 3)

  In the basic block which is a conventional technique, the lower layer portion is constituted by two prefabricated blocks, so that the respective prefabricated blocks are displaced from each other. Accordingly, each prefabricated block is likely to be displaced, and needs to be positioned so as to be abutted against each other. Further, since the shift is likely to occur, a step is generated between the prefabricated blocks. Accordingly, when the upper layer portion is arranged above the lower layer portion, it is difficult to arrange the upper layer portion horizontally. Even if the lower layer portion can be arranged horizontally, since the lower layer portion is constituted by two prefabricated blocks, only one of the two prefabricated blocks may cause subsidence, that is, unequal subsidence. As a result, the upper layer portion is stacked above the lower layer portion in a state inclined with respect to the horizontal. When the upper layer portion is stacked in a state inclined with respect to the horizontal as described above, the unit placed on the foundation block may be installed in a tilted state and fall down.

The support base structure 1 is configured by horizontally arranging a pedestal 2 at an installation location and laminating a block unit 3 above the pedestal 2. The upper direction is the thickness direction of the support base structure 1 and is the direction in which the placement object is placed on the support base structure 1. The support base structure 1 is formed with a pipe insertion hole 14 penetrating in the vertical direction in the thickness direction at a substantially central portion in the width direction and the longitudinal direction. In the present embodiment, the pipe insertion hole 14 is a hole having a substantially rectangular cross section viewed by cutting along a virtual plane orthogonal to the thickness direction of the support base structure 1. However, the pipe insertion hole 14 is not limited to such a shape, and the cross section may be formed in a substantially circular shape. The pedestal 2 and the block unit 3 are provided with positioning means 22 for positioning each other. The positioning means 22 includes a fitting protrusion 7, a fitting recess 10, and a fitting recess 16 described later.

However, it is not limited to a substantially rectangular parallelepiped if possible. The fitting concave portion 10 is arranged on the block unit laminated surface portion 8 so as to be fitted to the fitting protruding portion 7 in a state where the block unit 3 is laminated above the base 2. Specifically, one fitting recess 10 is formed in the vicinity of one end and the other end in the width direction of the pedestal lamination surface portion 6, and one in the middle portion in the longitudinal direction. Further, one fitting recess 10 is formed in the vicinity of one end and the other end in the longitudinal direction of the pedestal laminated surface portion 6, and is formed one by one in the intermediate portion in the width direction. In this way, four fitting recesses 10 are formed in the block unit laminated surface 8. In the present embodiment, four fitting recesses 10 are formed, but the number is not limited to four. The number of fitting recesses 10 may be two or three, and may be five or more, and the number is not limited. A placement surface portion 15 (hereinafter sometimes simply referred to as a “placement surface portion”) that is a surface portion opposite to the thickness direction of the block unit laminated surface portion 8 is formed so that a placement object can be placed thereon. An anchor hole 24 is formed in the mounting surface portion 15. The anchor hole 24 is a hole that is recessed in the thickness direction, and is formed so that an anchor bolt (not shown) that connects the mounted object and the support base structure 1 can be driven. In the present embodiment, the anchor hole 24 is formed by embedding a nut to which an anchor bolt can be screwed. Thus, the block unit 3 is formed so that the anchor hole 24 is formed and the anchor bolt can be driven.

Specifically, the two block bodies 4 are arranged in the horizontal direction, and the block units 3 are configured by abutting the side surfaces of the block bodies 4 with each other. However, the block unit 3 is not limited to what is comprised by the two block bodies 4, and may be comprised using the some block body 4 so that it may mention later. However, the block unit 3 is not limited to those formed of cement concrete, and is preferably formed of a material having lower mechanical strength than the base 2.

  As described above, the block unit 3 is constituted by the two block bodies 4. That is, the block body 4 is a block obtained by dividing the block unit 3 at the substantially longitudinal center. The block body 4 has a flat shape, and a cross-sectional shape viewed by cutting along a virtual plane orthogonal to the thickness direction of the block body 4 is formed in a U shape. The block body 4 has the same thickness as that of the block unit 3 and is formed such that surface portions perpendicular to the thickness direction are parallel to each other. Specifically, a block body recess 25 that is recessed toward the arrow Z1 direction shown in FIG. The block body recess 25 is formed by opposing wall surfaces of a pair of block body projecting portions 26 projecting in the arrow Z2 direction, which is the direction opposite to the arrow Z1 direction. Further, a portion where the block body recess 25 is formed is referred to as a block body recess 12. A side surface portion facing the arrow Z2 direction of the block body protruding portion 26 is referred to as a butt surface portion 11. The block unit 3 is configured by abutting the butting surface portions 11 of the two block bodies 4 against each other and arranging them in the horizontal direction. When the block unit 3 is configured in this manner, the block body recesses 25 are arranged so as to face each other, and the block unit pipe insertion hole 9 is formed by the block body recesses.

  The block body 4 is formed so as to be able to be stacked on the base 2. Specifically, the block body 4 is formed to be stacked above the pedestal 2 with the block body stacking surface portion 13 facing the pedestal stacking surface portion 6. The block laminate surface portion 13 is a surface portion perpendicular to the thickness direction. On the butting surface portion 11 of the block body 4, a fitting concave piece 16 that is recessed in the thickness direction of the block body laminating surface portion 13 and opens toward the butting surface is formed. The fitting concave piece 16 is formed so that the fitting concave portion 10 can be formed together with the fitting concave piece 16 formed in the other block body 4 when the two block bodies 4 are arranged to abut each other at the abutting surface portion 11. The block body 4 fitting recess 16 is formed so as to be able to engage with a part of the fitting protrusion 7 in a state where the block body 4 is laminated on the base 2. As described above, the block body 4 is configured so that the fitting concave piece 16 is engaged with a part of the fitting protruding portion 7 and can be stacked above the pedestal 2. By forming on the surface portion 11, the butt surface portion 11 is positioned when the fitting concave piece 16 and a part of the fitting protruding portion 7 are engaged. Further, in the block body laminated surface portion 13, a fitting recess 10 is formed in the center portion in the width direction near the end portion on the opposite side to the butting surface portion 11.

  Similarly to the block body stacking surface portion 13, the fitting concave portion 16 and the fitting concave portion 10 are formed in the block body mounting surface portion 20. The block body mounting surface portion 20 is a surface portion on the opposite side to the block body stacking surface portion 13 in the thickness direction. If it demonstrates concretely, the fitting recessed part 10 and the fitting recessed piece 16 and the block body which the fitting recessed part 10 and the fitting recessed piece 16 formed in the block body mounting surface part 20 will be formed in the block body laminated surface part 13 will be explained. 4 is formed so as to be substantially symmetric with respect to a virtual plane at the center in the thickness direction. In other words, the fitting concave portions 10 and the fitting concave pieces 16 formed in the block body stacking surface portion 13 and the block body mounting surface portion 20 have substantially the same horizontal position on a virtual plane orthogonal to the thickness direction. It is formed. Hereinafter, the fitting concave piece 16 formed on the block body mounting surface portion 20 is simply referred to as a counterbore piece 26, and the fitting concave portion 10 is referred to as a counterbore portion 17. Further, the fitting recess 16 and the fitting recess 10 formed in the block laminated surface portion 13 are simply referred to as the fitting recess 16 and the fitting recess 10. As described above, the fitting recess 10 and the spot facing 17 are associated with each other, and the fitting recess 16 and the spot facing 26 are associated with each other. By forming the spot facing piece 26 and the spot facing portion 17 in this way, the block body 4 can be stacked even when either the block body stacking surface portion 13 or the block body mounting surface portion 20 faces the pedestal stacking surface portion 6. Is done.

  The counterbore piece 26 forms the counterbore portion 17 together with the counterbore piece 26 formed on the other block body 4 when the two block bodies are abutted and arranged at the abutting surface portion 11 similarly to the fitting concave piece 16. The fitting concave piece 16 is formed with a fitting concave piece insertion hole 19a penetrating in the thickness direction at the bottom thereof. One end of the fitting concave piece insertion hole 19 a faces a recess formed by the fitting concave piece 16, and the other end faces a recess formed by the counterbore piece 26. A fitting recess insertion hole 19b that penetrates in the thickness direction is also formed at the bottom of the fitting recess 10. One end of the fitting recess insertion hole 19 b faces a recess formed by the fitting recess 10, and the other end faces a recess formed by the counterbore portion 17. When the fitting concave piece insertion hole 19a and the fitting concave part insertion hole 19b are collectively referred to, they are hereinafter referred to as bolt insertion holes 19. The bolt insertion hole 19 is formed so that the threaded portion of the bolt 21 can be inserted. The thread portion may include an incomplete thread portion. The bolt insertion hole 19 is formed so that the bolt head cannot be inserted. The bolt insertion hole 19 formed in this way is formed so that the bolt 21 inserted through the bolt insertion hole 19 is screwed into the insert nut 18 in a state where the block body 4 is laminated above the base 2. That is, the bolt insertion hole 19 and the hole formed by the insert nut are formed so as to face each other. One bolt insertion hole 19 is formed in the fitting recess 16, and two bolt insertion holes 19 are formed in the fitting recess 10. However, the number of bolt insertion holes 19 is not limited to such a number. When the bolt 21 is inserted, the head of the bolt 21 is placed in the counterbore recess formed by the counterbore piece 26 or the counterbore part 17. At this time, the counterbore piece 26 and the counterbore part 17 are formed so that the head of the bolt 21 is arranged substantially flush with the surface formed by the block body mounting surface part 20 or below the surface in the thickness direction. That is, the counterbore part 17 and the counterbore piece 26 can serve as a counterbore.

  As for the support base structure 1 which has such a structure, the base 2 is arrange | positioned horizontally. The block body 4 is stacked above the pedestal 2 so that the block body stacking surface portion 13 faces the pedestal stacking surface portion 6. A plurality of block bodies 4 are stacked above the base 2 in the same manner as described above. Since the pedestal 2 is horizontally arranged, the block bodies 4 laminated so as to face the pedestal laminated surface portion 6 can be arranged horizontally in parallel with each other. As a result, the block unit 3 configured by horizontally arranging a plurality of block bodies 4 can be stacked above the base 2.

  At this time, each block body 4 is formed such that the fitting recess 10 formed in each block body 4 is fitted with the fitting protrusion 7 and the fitting recess 16 is engaged with a part of the fitting protrusion 7. Arranged and stacked above the base 2. When the block unit 3 is stacked above the pedestal 2, the pedestal pipe insertion hole 5 and the block unit pipe insertion hole 9 face each other, and a pipe insertion hole 14 is formed in the width and longitudinal center of the support base structure 1. Can do. In the present embodiment, the pipe insertion hole 14 is formed by the pedestal pipe insertion hole 5 and the block unit pipe insertion hole 9, so that the cross section viewed by cutting along a virtual plane perpendicular to the thickness direction is substantially rectangular. Although formed, it is not limited to such a shape. For example, the cross-sectional shape may be formed in a substantially circular shape. At this time, the cross section viewed by cutting in a virtual plane orthogonal to the thickness direction of the base pipe insertion hole 5 and the block unit pipe insertion hole 9 is formed in a substantially circular shape. In this way, the support base structure 1 is configured. Further, in a state where the block body 4 is laminated on the base 2, the threaded portion of the bolt 21 is inserted into the bolt insertion hole 19 from above the block body mounting surface portion 20, that is, the mounting surface portion 15 in the stacking direction, and screwed into the insert nut 18. Can do. At this time, a washer is interposed between the seating surface of the head of the bolt 21 and the block body 4. If comprised in this way, the block body 4 can be pressed by a washer by tightening the bolt 21. As a result, the block body 4 is held between the washer and the base 2. Thereby, the block body 4 and the base 2 can be fastened.

  Further, when the block unit 3 is stacked above the pedestal 2 so that the block body mounting surface portion 20, that is, the mounting surface portion 15 faces the pedestal stacking surface portion 6, the fitting protruding portion 7 is fitted to the counterbore portion 17, The fitting protrusions 7 are stacked so that a part of the fitting protrusions 7 is engaged with the counterbore pieces 26. Further, when the base 2 and the block unit 3 are fastened by the bolt 21, the fitting concave piece 16 and the fitting concave portion 10 serve as counterbore. As described above, the support base structure 1 is formed by stacking the block unit 3 configured by arranging the two block bodies 4 on the base 2 and fastening the block body 4 and the base 2 with the bolts 21.

  FIG. 8 is a flowchart showing the construction procedure of the support base structure 1. FIG. 9 is a cross-sectional view schematically illustrating a part of the construction procedure of the support base structure 1. Below, the construction method for installing the said support stand structure 1 in a construction place is demonstrated. The construction method of the support base structure 1 includes a foundation work process, a pedestal laying process, which is a plate-like body laying process, a block unit placing process, and a placement object placing process. The construction of the support base structure 1 shifts from step s0 to step s1 by determining the installation position. In the present embodiment, the place where the pipe is buried is set as the installation place. Here, the piping includes wiring such as electric wiring.

  Step s1, which is a foundation work process, is a process of forming the foundation at the installation location. Step s1 includes a dug-down stage, a chestnut stone laying stage, a crushing stone laying stage, and a discarded concrete placing stage. When the installation location is determined, as shown in FIG. 9A, the installation location is dug down substantially vertically downward, that is, the local board 28 having the local board recess 27 recessed substantially vertically downward is formed. At this time, the buried pipe is arranged so as to protrude substantially vertically upward from the local board recess 27. The local board recess 27 is formed so that a cross section viewed by cutting along a virtual plane orthogonal to the depth direction is at least larger than a cross section viewed by cutting along a virtual plane orthogonal to the thickness direction of the support base structure 1. That is, the local board recess 29 forming the local board recess 27 is formed so as to be able to be fitted to a part of the support base structure 1. Here, the depth direction is a direction in which the local board recess 27 is dug down and is substantially vertically downward. In the present embodiment, a cross section viewed by cutting in a virtual plane orthogonal to the depth direction of the local board recess 27 is formed in a substantially identical rectangular shape as the support base structure 1. However, the local board recess 27 is not limited to such a shape, and may be any shape as long as a part of the support base structure 1 can be fitted. When the installation site is dug down, the stage shifts from the dugdown stage to the Kuriishi laying stage.

  At the Kuriishi laying stage, Kuriishi 30 is laid in the local board recess 27, and a Kuriishi layer 31 is formed. When the chestnut stone 30 is laid, a transition is made from the chestnut stone laying stage to the crushing stone laying stage. In the crushed stone laying stage, the crushed stone 32 is laid substantially vertically above the chestnut stone layer 31 to form a crushed stone layer. At this time, the crushing stones 32 are laid substantially vertically above the chestnut stone layer 31 without any gaps. When the crushed stone 32 is laid, the crushed stone laying stage shifts to the discarded concrete placing stage. In the discarding concrete placing stage, discarding concrete, for example, mortar is placed substantially vertically above the crushed stone layer 33 to form the discarding concrete base 34. At this time, the discarded concrete base 34 is formed such that the surface portion facing substantially vertically upward is substantially horizontal. At this time, since the discarded concrete base 34 is used for leveling, it is formed thinner than the support base structure 1. However, the discarded concrete base 34 is not limited to being formed thin, and may be formed thick. As shown in FIG. 9 (b), the chestnut laying step, the crushed stone laying step, and the scraping concrete laying step are performed in the local board recess 27, as shown in FIG. 9 (b). A foundation 35 is formed that is laminated in the order of the discarded concrete base 34. When the foundation 35 is formed, the chestnut layer 31, the crushed stone layer 33 and the discarded concrete base 34 are formed so that the buried pipe protrudes substantially vertically upward from the foundation 35. When the foundation 35 is formed in the local board recess 27, that is, the installation place in this way, the process proceeds from step s1 to step s2.

  Step s2 which is a pedestal laying step is a step of installing the pedestal 2 on the foundation formed in step s1. In step 2, the base 2 is installed horizontally on the foundation 35. Specifically, as shown in FIG. 9C, the pedestal 2 is installed on the foundation 35 so as to be fitted with the local board recess 29. Further, when the pedestal 2 is installed on the foundation 35, the pedestal 2 is installed so that the pipe that is embedded and protrudes substantially vertically upward passes through the pedestal pipe insertion hole 5 of the pedestal 2. The pedestal 2 is installed on a discarded concrete base 34 that is placed horizontally. At this time, the pedestal 2 is installed before the discarded concrete is dried, the level of the pedestal 2 is adjusted, and the pedestal 2 is installed horizontally. The pedestal 2 installed in this way is arranged such that the pedestal laminated surface portion 6 is substantially flush with the ground surface portion of the installation location. Therefore, the depth of the local board recess 27 is formed to be substantially the same as the thickness of the foundation 35 and the pedestal 2 in a state where the pedestal 2 is placed on the foundation 35. When the pedestal 2 is installed on the foundation in this way, the process proceeds from step s2 to step s3.

  Step s 3, which is a block unit placement step, is a step in which the block body 4 is placed above the pedestal 2 and the block unit 3 is stacked above the pedestal 2. In step 3, a plurality of block bodies 4 are placed in the horizontal direction above the pedestal 2. More specifically, as shown in FIG. 9D, the fitting protrusion 7 and the fitting recess 10 are fitted above the pedestal lamination surface portion 6 of the pedestal 2, and the fitting protrusion 7 Each block body 4 is laminated so that a part and the fitting recess 16 are engaged. Since the pedestal 2 is horizontally disposed and is formed in a substantially flat shape in the thickness direction, the block bodies 4 are arranged in the horizontal direction simply by being placed above the pedestal 2. Further, the position of the block body 4 with respect to the base 2 is determined by the fitting protrusion 7, the fitting recess 10 and the fitting recess 16. Therefore, the block unit 3 in which the butting surface portions 11 of the plurality of block bodies 4 are abutted with each other only by placing the block body 4 above the pedestal 2 is configured. As a result, the block unit 3 placed above the base 2 is configured. In this way, the block unit 3 can be placed above the pedestal 2 and the support base structure 1 can be formed at the installation location. Further, the bolt 21 is inserted into the bolt insertion hole 19, and the bolt 21 and the insert nut are screwed together to fasten the base 2 and the block unit 3. Thus, when the support base structure 1 to which the base 2 and the block unit 3 are fastened is formed, the process proceeds from step s3 to step s4.

  Step s4, which is a placement object placement step, is a process of placing the placement object on the support base structure 1 and connecting the placement object and the support base structure 1. Step s4 includes a placement stage and a connection stage. If a support body is formed in step 3, it will transfer to a mounting stage. In the placement stage, the placement object is placed on the placement surface portion 15 of the support base structure 1. When the placement object is placed, the stage shifts from the placement stage to the connection stage. In the connection stage, the mounted object and the support base structure 1 are connected by an anchor bolt. Specifically, an anchor bolt is inserted into a base formed on the mounting object, and the anchor bolt is screwed into an anchor hole 24 formed in the support base structure 1. By fastening the anchor bolt, the base formed on the mounting object and the support base structure 1 are fastened and connected. That is, the placing object and the support base structure 1 are connected, and the placing object is fixed and supported on the placing surface portion 15. Further, when the position of the anchor bolt inserted through the base and the position of the anchor hole 24 are deviated, that is, when the anchor bolt and the anchor hole 24 are not formed at corresponding positions, the anchor unit is attached to the block unit 3. Anchor holes 24 are formed at positions corresponding to the bolts. Anchor bolts are driven into the formed anchor holes to connect the placement object and the placement surface portion 15, and the placement object is fixed and supported on the placement surface portion 15. When a placement object is placed on and connected to the support base structure 1, the process proceeds from step s4 to step s5, and the procedure ends. The support base structure 1 is constructed by such a procedure, that is, a construction method.

  Thus, the support stand structure 1 comprised and constructed and its construction method have the following effects. When a placement object is placed and connected to the placement surface portion 15 of the support base structure 1, the center of gravity of the installation object constituted by the support base structure 1 and the placement object is lower than the center of gravity of the placement object. Can do. Thus, when the placing object is placed on the support base structure 1, it is possible to suppress the tipping over from the case where the placing object is installed alone. Specifically, by connecting the support base structure 1 to the lower side of the placement object, the weight of the installation object acting substantially vertically below the installation object becomes larger than that of the placement object. Therefore, the installation object is pressed down substantially vertically downward. This increases the moment acting in the direction in which the object can be pressed. Further, by taking the center of gravity downward, the distance between the fulcrum and the center of gravity when the installation object falls is reduced, and the moment acting on the installation object is reduced as compared with the case of a single object. The fulcrum at the time of falling is a point that becomes a fulcrum when the installation object falls. Since the moment acting in this way becomes small and the moment acting in the pressing direction becomes large, the effect of suppressing the falling of the installation object is high. By placing the placement object above the support base structure 1 in this manner, the fall of the installation object can be suppressed, that is, the fall of the placement object can be suppressed. Therefore, even when shaking occurs due to an earthquake or the like, it is possible to suppress the mounted object from falling with the support base structure 1 and to prevent the mounted object from falling and being damaged and damaged.

  Further, since the pedestal 2 is formed in a plate shape, there is no partial displacement as in the case where the pedestal 2 is configured to be separable, and no step is generated in the pedestal 2. That is, in the leveling operation of the pedestal 2, even when the pedestal 2 is partially hit and leveled, the pedestal 2 is integrally displaced and does not partially displace to cause a step. . Therefore, it is easy to arrange the pedestal 2 horizontally at the installation location. Moreover, when each block body 4 is mounted on the pedestal 2 installed horizontally in this way, since the pedestal 2 is a substantially flat plate-like body, the block bodies 4 can be arranged and supported side by side in the horizontal direction. Thereby, each block body 4 is stably installed and supported without being inclined. Therefore, the base 2 is formed in a substantially flat plate shape. Thus, since the base 2 is formed in plate shape, when the thickness of the base 2 is large, the weight of the base becomes large. Therefore, the base 2 is formed of resin concrete. Accordingly, the pedestal 2 can reduce the thickness and maintain the mechanical strength. Since the thickness of the base 2 is reduced, the weight of the base is reduced. Therefore, conveyance of the base 2 becomes easy. Therefore, it is possible to reduce the weight per person during transportation. Thus, by making the base 2 thin, the weight of the base 2 can be reduced. Thereby, the weight of the base 2 can be reduced to at least 55 kg or less. The weight of 55 kg is a weight that allows handling when a heavy object is handled by one person based on a notification from the Ministry of Labor. However, the weight of the base 2 is not limited to such weight. Moreover, the distortion of the base 2 can be made small by forming with concrete with high mechanical strength in this way. Thereby, the flatness of the pedestal laminated surface portion 6 of the pedestal 2 can be ensured. Furthermore, since mechanical strength is high, even if the block unit 3 is laminated | stacked or contacted, it can suppress that the base 2 is damaged and damaged.

  Since the pedestal 2 is formed in a plate shape and disposed horizontally, the plurality of block bodies 4 can be arranged in the horizontal direction only by placing them. In other words, the block unit 3 can be configured above the pedestal 2 simply by placing the plurality of block bodies 4 above the pedestal 2. Therefore, the block unit 3 can be configured easily. Further, since the block body 4 is formed in a flat shape, the placement surface portion 15 can be easily made substantially flat by arranging the plurality of block bodies 4 in the horizontal direction, and further can be arranged horizontally. As a result, the mounting surface portion 15 does not have a step and does not tilt, so that the mounted object placed on the mounting surface portion 15 does not tilt. Therefore, it is possible to suppress the fall of the mounted object. Further, since the block unit 3 is constituted by the two block bodies 4, the block unit 3 can be divided into two block bodies 4. Thereby, the block unit 3 can be divided into two block bodies and conveyed. Accordingly, it is possible to reduce the weight per person during transportation, and the block unit 3 can be easily transported. By dividing the block unit 3 in this way, the weight of the block body 4 can be reduced. Thereby, the weight of the block body 4 can be at least 55 kg or less. However, the weight of the block body 4 is not limited to such weight.

  A pedestal pipe insertion hole 5 is formed in the pedestal 2. As a result, the weight can be further reduced, and the pedestal 2 can be easily transported. A block unit piping insertion hole 9 is formed in the block unit 3. In other words, the block body recess 12 for forming the block unit pipe insertion hole is formed in the block body 4. As a result, the weight of each block body 4 can be further reduced, and the transport of the block body 4 can be facilitated. Furthermore, since the hole is formed in each of the pedestal 2 and the block unit 3, the volume formed is small and the material used can be reduced.

  Since the thickness dimension of the base 2 is formed small, the weight of the support base structure 1 is reduced. For this reason, in order to secure the weight of the support base structure 1 to a predetermined weight, for example, a weight necessary to make an earthquake-resistant structure, the thickness dimension of the block unit 3 that can be divided is increased, Secure. In this way, the thickness dimension of the block unit 3 formed so as to be separable is increased, and the thickness dimension of the base 2 formed in a single plate shape is decreased to reduce the weight. Accordingly, it is possible to easily construct the support base structure that can easily transport the block unit 3 and the base 2 and can secure a predetermined weight. Further, by increasing the thickness of the block unit 3, the surface of the mounting surface portion 15, that is, the mounting surface can be arranged at a certain height from the ground surface of the installation location. As a result, it is possible to prevent rain from accumulating and the object to be inundated.

  In the block body 4, the fitting concave piece 16 is formed on the abutting surface portion 11, so that a part of the fitting convex portion 7 and the fitting concave piece 16 are engaged to restrain the displacement of the abutting surface portion 11. That is, positioned. The block body 4 to be abutted also engages the other part of the fitting protrusion 7 and the fitting recess 16 to restrain the displacement of the abutting surface part 11. Therefore, the two block bodies 4 are restrained from shifting the butting surface portions 11 butted against each other. Accordingly, it is easy to arrange the block bodies 4 in a state of abutting each other and to stack them on the base 2. In other words, it is easy to configure the block unit 3.

  Since the fitting protrusion 7 protrudes in the thickness direction, when the pedestal 2 is displaced downward in the thickness direction, the block body 4 having the fitting recess 10 corresponding to each fitting protrusion 7 is guided to a predetermined position. can do.

  Since the pipe insertion hole 14 penetrating in the thickness direction is formed in the support base structure 1, when the support base structure 1 is installed at the installation location, an embedded pipe or the like is inserted through the pipe insertion hole 14. Thus, the support base structure 1 can be projected upward. Thereby, the piping and the placement object placed on the support base structure 1 can be easily connected. Specifically, an exhaust heat utilizing hot water supply and heating device is placed above the support base structure 1. Ten pipes such as a water supply pipe, a hot water supply pipe, and a gas pipe are connected to the exhaust heat utilization hot water supply and heating apparatus. In such a case, if it protrudes from a place different from the installation place and is connected to the exhaust heat-utilizing hot water supply / heating apparatus, the arrangement of the pipes becomes complicated. In the support base structure 1, since the pipe is inserted through the pipe insertion hole 14 and connected, the arrangement of the pipe can be simplified and the connection is easy. Moreover, when installing the support stand structure 1 in an installation place, you may bury the said wiring through-hole with discard concrete. As a result, the horizontal displacement of the support base structure 1 can be constrained.

  Further, the block body 4 can be stacked on the pedestal 2 regardless of which of the placement surface portion 15 and the block body stacking surface portion 13 faces the pedestal stacking surface portion 6, so that the fitting recess 10 and the spot facing portion 17 can be stacked. And the fitting concave piece 16 and the counterbore piece 26 are made to correspond to each other. Therefore, even when the anchor hole is mistakenly formed in the mounting surface portion 15, the anchor hole can be formed again by stacking so that the block laminated surface portion 13 faces upward. Even if the placement surface portion 15 is damaged, the placement object can be placed on the intact surface portion by placing the placement surface portion 15 upside down.

  Moreover, if the support base structure 1 is constructed by the construction method as described above, the pedestal 2 is installed on a discarded concrete base 34 formed at the installation location. It is possible to easily deform the discarded concrete base before the discarded concrete is dried. For this reason, before the discarded concrete is dried, the leveling can be performed by placing the pedestal 2 on the discarded concrete base 34 and hitting the pedestal 2. Since the pedestal 2 formed in advance is arranged on the discarded concrete base 34 in this way, it is easy to arrange the pedestal 2 horizontally.

  In the construction method of the present embodiment, the base 2 can be horizontally arranged on the foundation and can be installed at the installation location by simply placing the block body 4 thereon. As described above, the support base structure 1 can be configured by a simple operation simply by placing the base 2 and placing the block body 4 on the base 2, and requires specialized knowledge such as placing concrete. And not. Further, the block body 4 can be positioned with respect to the pedestal 2, that is, the block unit 3 can be positioned with respect to the pedestal 2 simply by fitting the fitting protrusion 7 and the fitting recess 10. Further, the base 2 and the block unit 3 can be fastened by the bolt 21. Therefore, it is easy to configure the support base structure 1 in which the base 2 and the block unit 3 are positioned and fastened and integrated. Further, by forming an anchor hole in the support base structure 1 in advance, it can be easily connected to the mounted object by driving an anchor bolt into the anchor hole.

  In such a simple work construction method, there is no waiting time for drying and the construction time is drastically shortened as compared with a conventional support base in which cement concrete is cast and dried. Specifically, although it took about 2 or 3 days to construct a conventional support base, the construction method of this embodiment can complete the construction in about half a day. In the conventional support base, when the support base is formed again at the existing installation location, it takes time to form the support base, and thus it is necessary to install a support base for transferring the placement object to another location once. In the support base structure 1, since it can construct in a short time, it is not necessary to move a mounting object to another place once. Therefore, when installing the support base structure 1, the operation | work which transfers a mounting object can be skipped. In addition, since the conventional support base is formed by casting cement concrete, it is difficult to perform construction on a rainy day outdoors. However, in this construction method, only the base 2 is installed on the foundation 35. So construction can be done even on rainy days. In addition, no cement concrete is used, so there is no need for a special vehicle for transport, such as a Mikisa vehicle. Furthermore, in the support base structure 1, since the base 2 is immediately installed in the foundation 35, it can suppress that the foundation 35 is stepped on and the surface part of the foundation 35 is dented and an unevenness | corrugation arises. Thereby, the flatness of the support base structure 1 can be ensured.

  Since the pedestal 2 is easily arranged horizontally as described above, the pedestal laminated surface portion 6 can be arranged in a horizontal state. For this reason, if the several block body 4 is laminated | stacked above the base lamination | stacking surface part 6, each block body 4 formed in a substantially rectangular parallelepiped can be arranged in a horizontal direction. Therefore, the plurality of block bodies 4 can be arranged horizontally only by stacking the plurality of block bodies 4 above the pedestal 2, that is, the pedestal stacking surface portion 6. Thus, the construction of the support base structure 1 is easy.

  When the plurality of block bodies 4 are stacked on the pedestal 2 as described above, the plurality of block bodies 4 are arranged horizontally, and the block unit 3 can be configured above the pedestal 2. The block unit 3 is laminated on the pedestal 2 so that the pedestal lamination surface portion 6 and the block unit lamination surface portion 8 face each other. Thereby, the block unit laminated surface portion 8 can ensure horizontality. Therefore, since the mounting surface portion 15 is formed substantially parallel to the block unit laminated surface portion 8, horizontality can be ensured. As a result, when placing a placement object on the placement surface portion 15, it is possible to maintain a state where the placement object is placed in a horizontal state and the placement object stands upright. Therefore, it can suppress that a mounting object falls.

  Moreover, since the block body 4 is laminated | stacked on the base 2 and it can maintain that the block body 4 is arrange | positioned horizontally and is supported by the base 2, it can suppress that each block body 4 displaces below. Therefore, it can be suppressed that any one of the plurality of block bodies 4 is displaced downward, that is, unevenly sinks and a step is generated between the block bodies 4. Therefore, when placing a placement object on the support base structure 1, it is possible to suppress the placement object from being inclined due to a step. Since it can suppress arrange | positioning in this way, it can suppress that a mounting object falls. Even when the block body 4 sinks, the block body 4 sinks and the pedestal 2 also sinks. At this time, since the plurality of block bodies 4 are supported by the base 2, they sink downward. Therefore, it can suppress that the block body 4 sinks unevenly and produces a level | step difference between the block bodies 4. FIG. Since the block body 4 is laminated on the pedestal 2, the pressure acting on the ground surface portion can be dispersed by the pedestal 2 even when a load acts on the block unit 3 locally. Therefore, it can suppress that the support stand structure 1 sinks.

  The block body 4 is laminated above the pedestal 2 by fitting the fitting recess 10 into the fitting protrusion 7. Therefore, the block body 4 is laminated in a state of being positioned on the base 2. Thereby, the block body 4 can be easily arranged at a predetermined position of the pedestal laminated surface portion 6. Moreover, since the fitting protrusion part 7 and the fitting recessed part 10 are fitted in the state in which the block body 4 and the pedestal 2 are laminated, the block body 4 and the pedestal 2 are displaced from each other in the horizontal direction. Can be suppressed. Therefore, the block body 4 can be prevented from falling off from the peripheral edge of the base 2. In other words, the block unit 3 can be prevented from falling off from the peripheral edge of the base 2. As a result, it is possible to prevent the block unit 3 from falling off the pedestal 2 and the mounted object connected to the block unit 3 from falling. By providing the four fitting protrusions 7 and the fitting recesses 10 as in the present embodiment, displacement in any of the longitudinal direction and the width direction can be restricted. Therefore, the horizontal displacement of the block unit 3 or the block body 4 can be suppressed. As a result, the block body 4 can be prevented from sliding off from the peripheral edge of the base 2.

  Further, the block unit 3 can be fastened to the pedestal 2 by the screw portion of the bolt 21 being inserted into the bolt insertion hole 19 and screwed into the insert nut 18. That is, the fitting protrusion 7 and the fitting recess 10 can be fastened by tightening the bolt 21 screwed into the insert nut 18. The pedestal 2 and the block unit 3 can be easily fastened by such a simple operation that only tightens. Since the base 2 and the block unit 3 are fastened, the vertical displacement of the block unit 3 with respect to the base 2 in the thickness direction can be prevented. Thus, even when the vertical shaking occurs due to an earthquake, the fitting protrusion 7 and the fitting recess 10 are not released from fitting, that is, the fitting protrusion 7 and the fitting recess. 10 does not come off. Therefore, it can suppress that the block unit 3 falls from the base 2. FIG. The head of the bolt 21 used for the fastening is disposed in a counterbore recess 36 formed by the counterbore portion 17. Therefore, since the head of the bolt 21 does not protrude from the surface on the mounting surface 15 side, the surface can be substantially flattened. Accordingly, the placement object can be installed by sliding the placement surface portion 15 in a sliding manner. Further, since the bolt is made of stainless steel, it does not rust. As a result, even if it is used outdoors for a long time, it will not rust and will not participate due to rain. Therefore, the support base structure 1 can be installed outdoors.

  In addition, by forming the positioning means 22 so as to form a convex portion instead of forming a concave portion in the pedestal 2 formed in a thin plate, the convex portion, in this embodiment, the fitting convex portion 7. However, the base 2 can be reinforced as a rib. Thereby, deformation of the base 2, specifically, deformation that is curved can be prevented, and the flatness of the base 2 can be maintained with high reliability. Therefore, the block bodies 4 can be provided so that the abutting surface portions 11 abut each other and are arranged in the horizontal direction.

  Moreover, the support base structure 1 is installed on the foundation 35 formed in an installation place. In other words, the support base structure 1 can be installed in any place where the foundation 35 can be formed. Therefore, the support base structure 1 can be installed in various places.

  Since the anchor hole 24 is formed in the block unit 3 in advance, the object to be placed is placed on the block unit 3, and an anchor bolt inserted into a base formed on the object to be placed is screwed into the anchor hole 24. Mounted objects can be connected. Thus, the block unit 3 and the mounted object can be easily connected, that is, the support base structure 1 and the mounted object can be easily connected. Further, since the anchor hole 24 is formed in advance, it is not necessary to form the anchor hole 24 using a vibration drill or the like at the installation location. Therefore, vibrations and noise from a vibration drill or the like can be prevented. Moreover, since a tool is not required, electricity can be used and cost can be reduced.

  Further, the block body 4 is formed of cement concrete, that is, the block unit 3 is formed of cement concrete. As a result, the block unit 3 and the block body 4 have lower mechanical strength than the base 2 and can easily form anchor holes. Therefore, when the placement object is placed on the support base structure 1, when an anchor hole corresponding to the placement object is not formed, such as a position where the anchor bolt is inserted into the placement object is not aligned with the position of the anchor hole, a new corresponding anchor is formed. Holes 24 need to be formed. Even in this case, it is easier to form anchor holes in the block unit 3 and the block body 4 than in the base 2. Therefore, also in this construction method, when forming the anchor hole corresponding to an installation thing at step s4 which is a mounting object mounting process, it can form easily.

  In the conventional support table, the finish of the support table differs depending on the method of placing the cement concrete by the installer and the drying time. In the support base structure 1, since it can construct with such an easy operation | work, the finishing condition of the support base structure 1 is substantially the same by the installer. Moreover, the support base structure 1 does not need to be constructed by a specialist such as a plasterer, and does not matter to the installer. Furthermore, the support base structure 1 can be divided into a pedestal 2 and a block body 4, and the weight can be reduced to a weight that the pedestal 2 and the block body 4 can be easily transported. Thus, the support base structure 1 can be easily constructed regardless of the installer.

  The foundation 35 is formed by sequentially laminating a chestnut layer 31, a crushing stone layer 33, and a discarded concrete base 34. The foundation 35 laminated in this way can form a gap 37 between the chestnut stones 30 on which the chestnut stone layer 31 is laid, and can buffer vibrations and shocks. That is, the seismic isolation effect can be obtained by the gap 37 formed in the chestnut layer 31. Further, the crushed stone layer suppresses that the discarded concrete placed above enters the chestnut layer 31 formed below and blocks the gap 37 formed in the chestnut stone. Thereby, the seismic isolation effect of the Kuriishi layer 31 can be maintained. The discarded concrete base 34 facilitates the installation of the support base structure 1 and facilitates the horizontal placement of the base 2.

  The block unit 3A includes two block bodies 4A. Specifically, the side surfaces facing each other of the two block bodies 4 are arranged in a horizontal direction with a predetermined distance apart, that is, arranged side by side in a getter shape. The predetermined distance is substantially the same as the width of the base pipe insertion hole 5 formed in the base 2A. The block unit 3A is formed so as to be able to be stacked on the base 2A. The block body 4A is generally formed in a substantially rectangular parallelepiped. The block body 4A is formed so that a part of the side surface of the pedestal 2 and the side surface excluding one side surface in the width direction of the block body 4A are substantially flush with each other when stacked on the pedestal 2. As for block body 4A, engagement concave piece 42 is formed in the peripheral part except the width direction one end part of block body lamination side surface part 13. FIG. The engagement concave piece 42 is formed so as to open from the peripheral portion toward one side and the side in the thickness direction. That is, the engagement concave piece 42 is formed by forming a step in the peripheral edge from the outside toward the inside. Here, the side surface of the block body 4A is a surface substantially parallel to the thickness direction. The engaging concave piece 42 is configured to be able to engage with a part of the engaging convex portion 38 in a state where the block body 4A is stacked on the base 2A.

Furthermore, the pedestal 2A and the block unit 3A can be fastened with bolts 21 to form the support base structure 1A in which the block units 3 formed in a getter shape are stacked on the pedestal 2A. The placement object that can be placed on the getter foundation is a placement object that satisfies the following conditions. The condition is that the width of the placement object is larger than the height of the placement object. Most mounted items such as water heaters have a width smaller than the height and do not satisfy the above conditions. In the support base structure 1A, the block unit 3A is formed in the shape of a getter base, but since it is stacked above the pedestal 2A, it can exhibit the same function as the solid base and can also function as a getter base. it can. Further, since the support base structure 1A is formed in a getter base shape, the material can be reduced.

  Further, since the fitting recess 10A is formed in a tapered shape, the opening surface is wide and the fitting protrusion 7 can be easily fitted. Since the fitting recess 10A is formed in a taper shape, even when the block body 4A is placed with a slight shift to the base 2A, the fitting protrusion 7 is guided by the side surface of the fitting recess 10, Positioning of the block body 4A can be facilitated. Since the side surface portion of the engaging concave piece 42 is also tapered, the engaging convex portion 38 is guided by the side surface portion of the engaging concave portion 39 as described above, and positioning of the block body 4A can be facilitated. . Further, in the support base structure 1A and the pipe insertion holes 14 of the support base structure 1A, the restraining bodies 40 are inserted in the vicinity of the four corners.

Furthermore, by forming the pedestal recess 41 on the side surface of the pedestal 2A, it becomes easy to put a finger on the pedestal recess 41 during transport, and the pedestal 2A can be gripped and transported. This facilitates conveyance. Furthermore, since the drain hole 47 is formed in the fitting recess 10, it is possible to suppress rain and the like from accumulating in the fitting recess 10 and to prevent the bolt 21 from rusting. Further, by forming the engaging convex portion 38 at the peripheral portion, the pedestal 2A can be reinforced as a rib as compared with the case where only the fitting protruding portion 7 is formed. Thereby, the deformation of the pedestal 2A, specifically, the deformation that is curved can be prevented, and the flatness of the pedestal 2 can be maintained with high reliability. Therefore, the block bodies 4A can be arranged in the horizontal direction.

In addition, anchor holes 24 penetrating in the thickness direction are formed on both surface portions in the thickness direction of the first block body 4Ba. Here, in the surface portion perpendicular to the thickness direction of the first block body 4Ba, one is a first laminated surface portion 45 and the other is a second laminated surface portion 46. Further, in the first block body 4, the first block engaging recesses 42 </ b> Ba are formed in part of the peripheral edge portions of the first stacked surface portion 45 and the second stacked surface portion 46.

Further, on both surfaces in the thickness direction of the second block body 4Bb, third fitting recesses 16Bc that penetrate in the width direction and are recessed in the thickness direction near both ends in the longitudinal direction of the second block body 4Bb are formed. The third fitting recess 16 </ b> Bc forms a part of the second fitting recess 10 </ b> Bb, and is arranged to face the second fitting recess 16 to form the second fitting recess 10. At the bottom of the third fitting concave piece 16, a bolt is inserted from the third fitting concave piece 16 formed on one surface portion in the thickness direction to the third fitting concave piece 16 formed on the other surface portion in the thickness direction. A hole 19 is formed. Further, a second block body engaging concave piece 42Bb is formed at both ends in the longitudinal direction of the second block body 4Bb, and a step is formed from the outside toward the inside. The second block body engaging concave piece 42Bb forms a part of the fitting concave portion 10 formed in the block unit 3B.

Specifically, the block unit 3B has a horizontal portion that butts the surface portion perpendicular to the width direction of the second block body 4Bb and the second butting surface portion 11Bb of the first block body 4 constituting the divided block unit 3Ba. Composed by lining up. When the block unit 3B is configured in this way, the divided block unit 3Ba is formed in a U-shape, and therefore, by arranging the two divided block units 3Ba and the second block body 4Bb to face each other, as described above First and second block unit pipe insertion holes 9Ba and 9Bb can be formed. Thus, the block unit 3B as described above can be configured. The block unit 3B configured in this manner fits the first fitting protrusion 7Ba and the first fitting recess 10Ba, and connects the second fitting protrusion 7Bb and the second fitting recess 16Bb. The engaging projections 38 and the engaging recesses 39 are engaged with each other, and are stacked above the base 2B. In a state where the block unit 3B is stacked on the pedestal 2B, a bolt is inserted through the bolt insertion hole 19 and screwed into an insert nut 18 formed on the pedestal 2B, thereby fastening the block unit 3B and the pedestal 2B. Further, in the support base structure 1B, the base pipe insertion hole 5B formed in the base 2 can be disposed so as to face either of the first and second block unit pipe insertion holes 9Ba, 9Bb. That is, the position of the pipe insertion hole 14B of the support base structure 1B can be changed.

  Thus, since the support base structure 1B can be divided into the base 2B, the four first block bodies 4Ba, and the second block bodies 4Bb, the weight per one can be further reduced and the conveyance is easy. . Moreover, it forms so that the surface part which faces the block unit piping insertion hole of division | segmentation block unit 3Ba may incline. This is because the first block body 4Ba is of a vertical type, and if the surface portion is not inclined, bubbles do not escape and the appearance deteriorates. Further, a large nest is generated, and the mechanical strength of the first block body 4Ba is lowered. Therefore, by forming the slope in this way, bubbles can be easily removed, the appearance can be improved, and the mechanical strength can be increased. Further, by chamfering the joint portion between the inclined surface portion and the adjacent surface portion, bubbles can be easily removed, the appearance can be improved, and the mechanical strength can be further increased. Further, since the fitting recess 10 is formed in the first and second butting surface portions 11Ba and 11Bb, the positioning of the first and second butting surface portions 11Ba and 11Bb is easy. That is, the positioning of the first and second block bodies 4Ba and 4Bb is easy. Thereby, the shift | offset | difference of 1st and 2nd block body 4Ba, 4Bb can be suppressed. Further, the position of the pipe insertion hole 14B in the support base structure 1 can be changed according to the position where the pipe is buried. Moreover, since the block unit 3B can be comprised by the 1st block body 4, it is not necessary to form the block body from which a some shape differs. Therefore, there is no need to form a plurality of shapes, cost can be reduced, and mass production can be achieved. Thus, the block unit 3 of various shapes can be comprised by forming the block body 4 in various shapes. Also, the shape and position of the pipe insertion hole 14 can be changed by changing the shape of the block body 4.

  In the present embodiment, the positioning means 22 is constituted by the fitting convex portion 7, the fitting concave portion 10 and the fitting concave piece 16, but is necessarily constituted by the fitting convex portion 7 and the fitting concave portion 10. It is not limited to things. For example, a convex part may be provided on the pedestal laminated surface part 6 and the block body 4 may be sandwiched by the convex part.

By forming the foundation 35 at the installation location in this manner, the support base structure 1 can be installed at the installation location in a state suitable for installing the installation location.

  According to the support base structure 1 of the present invention, the support base structure 1 can be divided and transported into the base 2 and the block unit 3, and the block unit 3 can be transported while being divided into a plurality of block bodies 4. The body 1 can be easily transported. Therefore, when constructing the support base structure 1, specialized knowledge is not required, and the block unit 3 can be easily transported. Therefore, the support base structure can be easily constructed.

  According to the support base structure 1 of the present invention, the fastening means 23 is composed of the stainless steel bolts 21, so that the base 2 and the block unit 3 can be connected and integrated by simply tightening the bolts 21. it can. Accordingly, it is possible to prevent the block unit 3 from being displaced in the horizontal direction due to an earthquake or the like and falling from the pedestal 2. Therefore, it can suppress that the block body 4 which comprises the block unit 3 falls from the base 2 and sinks unevenly. Furthermore, the stainless steel bolt 21 does not rust even if rain or the like adheres. Therefore, even when the support base structure is used outdoors, the screw member can be prevented from being rusted due to rain or the like and being damaged.

  According to the support base structure 1 of the present invention, since the pedestal 2 is made of concrete having high mechanical strength, even if the block body 4 is placed, it is not damaged or damaged, and the distortion is small. Therefore, it is possible to support the block body 4 while maintaining the state in which the block bodies 4 are horizontally arranged and stacked with the base 2 facing upward. Moreover, since the thickness of the base 2 can be reduced and the thickness of the support base structure 1 can be reduced, the center of gravity of the support base structure 1 can be taken downward, and rollover can be suppressed. Furthermore, since the block unit 3 is made of concrete having low mechanical strength, an anchor bolt can be driven. Therefore, by stacking the block unit 3 on the base 2, the anchor bolt can be easily driven into the upper surface portion of the support base structure 1. As a result, the support base structure 1 and the device mounted on and supported by the support base structure 1 can be fastened by the anchor bolt.
