  Considering the basics of a cogeneration system equipped with a power generation unit and a hot water storage unit, as shown in Patent Document 1 and Patent Document 2, it is easy to work by constructing a foundation by combining multiple blocks with a fixed structure To. In other words, those using a block with a fixed structure do not require formwork compared to those in which concrete is cast to construct a foundation, and even when using concrete, the amount used is small, Compared with the case of using a single block having a size corresponding to the area of the foundation, one block has a favorable aspect that it is easy to handle because the weight is reduced.

  Taking a cogeneration system as an example, there are usually several types of power generation capacity of the power generation unit and the amount of hot water stored in the hot water storage unit, and the installation areas are also different. Therefore, it is necessary to use blocks having different sizes in order to cope with such multiple types of installation areas. However, in the case of using a block having a size corresponding to a different installation area, it is necessary to manufacture a plurality of types of blocks, and there is room for improvement in terms of complicating the process for manufacturing the block. is there.

  Therefore, it is conceivable to use a relatively large block that can be used as a basis for a unit having a large installation area. However, when this type of block is used as a basis for a unit having a small installation area, the foundation ( Since the end of the block was unnecessarily overhanging, it was thought that it would be an obstacle to installation.

  An object of the present invention is to rationally configure a basic block that can accommodate different installation areas.

A feature of the present invention is a basic block having a support surface formed on the upper surface,
Side surfaces are formed at both ends in the width direction of the block body, the support surface and a connection surface at a lower level than the support surface are formed on the upper surface side of the block body. The support surface is formed with a fastening portion for fastening a device to be supported on the support surface on a virtual straight line that is equidistant from the pair of side surfaces or at a symmetrical position across the virtual straight line. The connecting surface is formed with a connecting portion for connecting the block main bodies at positions symmetrical with respect to the virtual straight line.

  According to this configuration, one of the pair of foundation blocks is rotated 180 degrees in plan view, the ends of the coupling surfaces are opposed to each other, the foundation block is arranged along the direction of the imaginary straight line, By arranging a plate or the like on the upper surface and connecting the plate or the like to the connecting portion, a pair of foundation blocks can be integrated and used as a foundation. In this way, when connecting the basic blocks, the connecting portion is arranged at a position sandwiching a line where the end faces of the connecting faces face each other in plan view (at a symmetrical position), so that the connecting structure is facilitated. Similarly, since the fastening portion is disposed at a position (symmetrical position) between the lines where the end faces of the connecting surfaces face each other in plan view, devices such as a cogeneration system can be fastened and supported at this fastening portion. . In particular, since the connection surface is formed at a lower level than the support surface, even when the connection surface is connected using a plate or the like, the plate or the like is not projected upward from the support surface. Furthermore, with a pair of basic blocks arranged with the end faces of the connecting surfaces facing each other in plan view as one basic unit, a plurality of basic units are arranged in parallel in the width direction of the block body (direction perpendicular to the virtual straight line) And what integrated the some block main body by connecting each foundation block in a connection part can be used as a foundation. Thus, the basic block which can respond also to a different installation area was comprised rationally.

  According to the present invention, the block body is formed of a concrete material, and the fastening portion is configured by a nut embedded under the support surface, or a screw portion protrudes upward from the support surface. Moreover, you may comprise with the volt | bolt which embedded a part under this support surface. According to this, for example, even when supporting devices, it is only necessary to screw a bolt into a nut embedded in the block main body or to screw a nut into a screw portion of a bolt protruding from the block main body. It becomes easy.

  In the present invention, the block body is formed of a concrete material, and the connecting portion is configured with a nut embedded under the connecting surface, or a screw portion protrudes upward from the connecting surface. Thus, you may comprise with the volt | bolt which embedded a part under this connection surface. According to this, even when a plate or the like is used to connect the block main bodies, the bolts are screwed into the nuts embedded in the block main bodies, or the nuts are screwed into the screw portions of the bolts protruding from the block main bodies. It is easy to work.

  In the present invention, the support surface is formed flat, and the connection surface is formed flat in a posture parallel to the support surface, and the width direction is the end of the connection surface opposite to the support surface. You may form the recessed part used as the shape which notches the center position in in this connection surface. According to this, by forming a recess in the block body, not only can the weight of the block body be reduced, but also the block body is arranged along the direction of the imaginary straight line with the ends of the connecting surfaces facing each other in plan view. In this case, the person who performs the work can easily insert his / her hand or the tool into the recess or insert tools, thereby improving workability.

It is an integrated point.

  According to this configuration, a plurality of basic units are arranged in parallel to the width direction of the block main body (direction orthogonal to the imaginary straight line), with a pair of blocks arranged with the end faces of the coupling surfaces facing each other in plan view as one basic unit. The base structure can be constructed by arranging the plates on the upper surfaces of the connecting portions of the respective connecting surfaces and connecting the plates to the connecting portions to integrate the plurality of block bodies. In particular, when a plurality of block bodies are connected in plan view, each block body is in a reverse orientation (post-rotated 180 degrees), but the fastening portion of the support surface of each block body is arranged on a virtual straight line Therefore, even when a plurality of basic units are used, the lines connecting the respective fastening portions in a plan view are rectangular and there is no difficulty in supporting the devices. Therefore, the foundation structure which can respond to different installation areas was obtained.

A concave portion TC having a shape in which a central position in the direction of the width X is cut out at an end portion on the opposite side to the support surface S of the connection surface T is formed. Thus, by forming the concave portion TC at the center position in the width X direction, the connection surface T is disposed at two locations that are both end portions in the width X direction in appearance.

  Assuming a virtual straight line L that is equidistant from the side surface U in a plan view, the second base block E2 is assumed to have a flat side surface U in a vertical orientation at the end position in the width X direction. In the plane S, fastening nuts Ns serving as fastening portions are embedded at two positions that are symmetrical with respect to the virtual straight line L in a plan view, and on the side opposite to the connection surface from the position where the fastening nut Ns is embedded. A management nut Nc is embedded as a management fixing portion on the virtual straight line L in FIG. An engagement hole h is formed on the bottom surface V side of the second base block E2.

Then, a third connecting plate 13 made of metal such as iron or stainless steel is placed on the upper surface of the connecting surface T adjacent to the second base block E2, and is inserted into the through hole of the third connecting plate 13. The plurality of second foundation blocks E2 are integrated by screwing and tightening the bolt 10 to the connecting nut Nt.

  By connecting the pair of second base blocks E2 and E2 in this manner, the fastening nuts Ns of the pair of second base blocks E2 and E2 are arranged at positions that are symmetrical with respect to the end surface Ts of the connection surface T. A line (not shown) connecting the plurality of fastening nuts Ns in a plan view is rectangular.

[Installation procedure / ground]
An example of the procedure for constructing the foundation structure C of the present invention on the ground G is shown in the flowchart of FIG. In this procedure, the ground G is first excavated, and, as shown in FIGS. 7A and 7B, the mortar 22 is placed after the grindstone 21 is laid on the excavated portion and the ground is solidified (# 101). , # 102 step).

  This step shows an example of groundwork that hardens the ground, and it is not necessary to use grits. Use grits and gravel together, use only gravel, or use a rammer. You may just do the work which solidifies.

  Next, as shown in FIG. 7B, a flat reference plate 23 is brought into close contact with the upper surface of the mortar 22, and the amount of inclination of the reference plate 23 is measured with a level or the like to adjust the inclination of the upper surface of the mortar 22. Leveling is performed, and the basic blocks E1 and E2 are arranged after the required level is obtained (steps # 103 and # 104).

  In this step, in order to obtain the level, the top surface of the previously placed mortar is formed, a part of the mortar is removed, or the mortar is further added. The number of second foundation blocks E2 to be installed is a number corresponding to the installation area of the hot water storage unit B.

  Next, as shown in FIG. 7 (c), FIG. 4, and FIG. 5, the base blocks E1 and E2 are inserted into the first connecting plate 11, the second connecting plate 12, and the third connecting plate 13 with bolts 10 inserted. Then, the amount of inclination of the support surface S of each foundation block E1, E2 is measured with a level or the like in a temporarily connected state where it is lightly screwed to the corresponding nut, and a level is obtained to adjust the amount of inclination, After the required level is obtained, the main connecting and fixing for tightening the bolt 10 is performed, the power generation unit A is installed on the support surface S of the first foundation block E1, and the hot water storage unit is installed on the support surface S of the second foundation block E2. B is installed (steps # 105 to # 108).

  As a specific example of the situation in which the unit (superordinate concept of the power generation unit A and the hot water storage unit B) is installed on the support surface S of the basic block E (superordinate concept of the first basic block E1 and the second basic block E2) in this way. In the case where the hot water storage unit B is supported on the support surface S of the second foundation block E2, the bolt 32 penetrating the connecting piece 31 at the bottom of the hot water storage unit B is screwed into the fastening nut Ns and tightened as shown in FIG. Is done.

  Also, the wiring 34 can be supported on the bracket 33 by screwing the bolt 32 inserted into the wiring support bracket 33 set on the support surface S into the management nut Nc and tightening. As shown in the drawing, a tube 35 for sending a heat medium from the power generation unit A to the hot water storage unit B can be arranged in a space formed above the connection surface T of the second foundation block E2. Although not shown in the drawings, a support bracket is provided for the support surface S of the first foundation block E1, and the wiring is supported on the bracket, or above the connection surface T of the first foundation block E1. Tubes may be arranged in the space to be formed.

  When the first foundation block E1 or the second foundation block E2 is installed, the screw nut 16A of the handle 16 shown in FIG. 5 is screwed into the fastening nut Ns or the connecting nut Nt. When the performer grips the handle 16, the handleability when installing the first foundation block E1 or the second foundation block E2 is improved.

  Thus, when installing the foundation blocks E1 and E2 on the top surface of the mortar 22, anchor bolts or the like that fit into the through holes H or the engagement holes h formed on the bottom surface V of the foundation blocks E1 and E2 are embedded in the mortar 22. The positioning may be performed by fitting the upper end of the anchor bolt or the like into the through hole H or the engagement hole h.

[Installation procedure / concrete surface]
The procedure for constructing the foundation structure C of the present invention on the upper surface of the inclined concrete D is shown in the flowchart of FIG. In this procedure, anchor bolts 41 are fixed to the holes first drilled in the concrete D, and the mortar 22 is placed on the upper surface of the concrete D as shown in FIG. A level plate such as adjusting the inclination of the upper surface of the mortar 22 by measuring the amount of inclination of the reference plate 23 with a level or the like (steps # 201 to # 203).

  The anchor bolt 41 shown in the figure has an anchor portion 41A and a bolt portion 41B, and shows an example in which the diameter of the anchor portion 41A is enlarged and fixed to the hole portion by rotating operation of the bolt 41B. The anchor bolt 41 may be driven into a simple one.

  As described above, the operation of placing the mortar 22 on the upper surface of the concrete D is performed such that the upper surface of the concrete D is inclined like “dog running” formed around the house, or the upper surface of the concrete D is appropriately horizontal. This is an operation performed when it is not in a state, and need not be performed if the upper surface of the concrete D is in an appropriate horizontal state.

  As shown in FIG. 10, when leveling the mortar 22 placed on the upper surface of the inclined concrete D, the upper surface of the nut 42 (preferably a double nut) screwed to the bolt portion 41B is used. The washer 43 is arranged, and the upper surface of the washer 43 is made to coincide with the upper surface of the mortar 22 by adjusting the vertical position of the nut 42.

  Moreover, the through-hole H formed in the bottom face V of the 1st foundation block E1 arrange | positioned on the low side of an inclined surface among the upper surfaces (concrete surface) of concrete D, or the low side of an inclined surface is arrange | positioned among concrete surfaces. The anchor bolt 41 is disposed at a position corresponding to the engagement hole h formed in the bottom surface V of the second foundation block E2.

  Next, the foundation blocks E1 and E2 are arranged on the upper surface of the mortar 22. When arranged in this way, the upper end of the anchor bolt 41 is inserted into the through hole H and the engagement hole h. Then, the bolts 10 are inserted into the first connecting plate 11, the second connecting plate 12, and the third connecting plate 13, screwed into the corresponding nuts, and the main connecting and fixing for tightening the bolts 10 is performed. The power generation unit A is installed on the support surface S of E1, and the hot water storage unit B is installed on the support surface S of the second foundation block E2 (# 204 to # 206 steps).

  A specific example of installing a unit (superordinate concept of the power generation unit A and the hot water storage unit B) on the support surface S of the basic block E (superordinate concept of the first basic block E1 and the second basic block E2) is as follows. The installation procedure for the ground is the same as that described above, and the wiring 34 is supported on the bracket 33 and the arrangement position of the tube 35 is the same as described above.

  A structure in which two first base blocks E1 are connected to support the power generation unit A and a structure in which a plurality of second base blocks E2 are connected to support the hot water storage unit B are separated as in the base structure described above. In the arrangement, the respective structures are separated from each other, so that the power generation unit A and the hot water storage unit B can be supported without increasing the relative arrangement accuracy. However, earthquake resistance may be improved by connecting a structure in which the two first base blocks E1 are connected to support the power generation unit and a plurality of second base blocks E2 to support the hot water storage unit B.

  Although not shown in the drawings, when connecting the first basic block E1 and the second basic block E2, the first basic block E1 and the second basic block E2 are brought close to each other, and the first basic block E1 and the second basic block E2 are connected. The third connection plate 13 is placed over the two foundation blocks E2, and the bolts 10 inserted through the through holes of the third connection plate 13 are screwed into the connection nuts Nt on the connection surface T of the first foundation block E1. The first foundation block E1 and the second foundation block E2 are integrated by screwing the connection nut Nt of the connection surface T of the second foundation block E2. This connection is possible because the distance D1 and the distance D2 described above are matched in the first basic block E1 and the second basic block E2. The third connection plate 13 can be shared with the first connection plate 112, and can be used as a connection plate when connecting the foundations of the power generation unit A and the hot water storage unit B.

  Thus, since the basic block E of the present invention forms a stepped level difference between the support surface S and the connection surface T, the first connection plates 11, 12, and 13 are connected to the connection surface T. By mounting and connecting with bolts 10, a plurality of foundation blocks E can be integrated to construct a foundation structure. Further, in the present invention, a unit obtained by connecting one of the pair of base blocks E by rotating 180 degrees is used as a base unit. Therefore, the basic structure corresponding to the installation area of the equipment supported by the unit or the like can be constructed by using one basic unit or connecting a plurality of basic units. In the present invention, the fastening portion formed on the support surface S of the foundation block is arranged at a position that is symmetrical in the width direction, so that the contact surface can be contacted even when the orientation of the foundation block is rotated 180 degrees in plan view. The position of the fastening portion is arranged at a position that is symmetric with respect to each other, so that the unit and the devices can be supported in a rectangular area in a plan view.

  In particular, since the connecting surface T is formed at a lower level than the support surface S, even when the connecting plates 11, 12, 13 are mounted on the connecting surface T and connected, the connecting plates 11, 12, 13 By avoiding the inconvenience of projecting upward from the support surface S, the flat support surface S can be used to support the unit and equipment, and the upper surface of the connection surface T is formed in a concave groove shape. Therefore, the tubes can be arranged by effectively using the space formed above the connecting surface T.

[Another embodiment]
The present invention may be configured as follows in addition to the embodiment described above.

(A) The bolt may be protruded upward from the support surface by embedding a part of the bolt in the block body as a fastening portion formed on the support surface.

(B) As a connecting portion formed on the connecting surface, a part of the bolt may be embedded in the block main body to project the bolt upward from the connecting surface.

(C) Even if it is provided with two units like the power generation unit A and the hot water storage unit B, for example, it is configured to construct a foundation corresponding to the two units by combining only the second foundation block E2. You may do it. In this way, in the case of constructing a foundation with a combination of one type of foundation block, the complexity of producing a plurality of kinds of foundation blocks is eliminated, and the work for constructing the foundation is further simplified.
