  By the way, outdoor equipment fixed to such a base device is often a relatively large and heavy device, and it is necessary to stably install outdoor equipment even if a phenomenon such as an earthquake occurs. It is. As a structure for fixing the concrete block that is the main body of the base device to the ground, there is also known a technique of deeply embedding a nail member such as an anchor through which the concrete block is inserted into the ground. In the case of a large earthquake that causes an earthquake disaster with the structure used, sufficient resistance strength cannot be obtained, and there is a concern about falling or tilting.

  SUMMARY OF THE INVENTION In view of the above technical problems, an object of the present invention is to provide a base device with excellent seismic performance that realizes stable installation that prevents a fall or tilt due to an earthquake or the like.

In order to solve the above technical problem, an earthquake-resistant base device of the present invention includes a block-shaped base body on which an outdoor device installed outdoors is mounted, and a device that connects the base body and the outdoor device. A connecting member, a plurality of underground connecting members extending from the base main body into the ground, and an embedded plate that is attached to the lower end of the plurality of underground connecting members and embedded in the ground. Features.

In addition, the structure of the buried board can be made stronger by combining a plurality of sheets or combining with mortar, for example, and construction according to the restrictions in the ground is possible, and the construction range can be expanded.

  An earthquake-resistant base device according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a place where an earthquake-resistant base device according to an embodiment of the present invention is constructed. The earthquake-resistant base device 10 includes a block-shaped base main body 11 on which an outdoor device installed outdoors is placed, and a rail member 12 arranged as an example of a device connecting member that connects the base main body 11 and the outdoor device. The base body 11 includes a connecting rod 13 constituting a part of the underground connecting member extending from the base body 11 to the ground, and a buried plate 14 attached to the lower end of the connecting rod 13. 11 is installed so as to be buried in the ground from the bottom to the bottom. In FIG. 1, the soil between the buried plate 14 and the base body 11 is illustrated except for the soil between the buried plate 14 and the base body 11. However, during actual construction, between the buried plate 14 and the base body 11 as shown in FIG. Embedded with other filling materials.

  The predetermined outdoor equipment supported by the earthquake-resistant base device 10 of the present embodiment is, for example, equipment such as an outdoor unit, a boiler, a tank, a water heater, an operation panel, a vending machine, etc. of an air conditioning equipment, and is relatively heavy. Typically, it refers to devices that are installed in places where the ground is exposed, such as outside the building.

  The block-shaped base body 11 includes a pair of concrete base members 21 and 22 disposed substantially in parallel at a predetermined interval at a place where predetermined equipment is to be installed, and the base members 21 and 22. It has the structure which combined the three horizontal connection members 23, 24, 25 made from concrete which have the fitting recessed part fitted to the upper plane part of both ends, and three base members 21 and 22 have three The horizontal connecting members 23 to 25 are combined to serve as a base part for supporting predetermined equipment. The pair of base members 21 and 22 have the same shape and structure, and form a pair by changing the left and right directions. The pair of base members 21 and 22 are concrete block materials that are produced as a whole under the management of raw materials and processes in a factory, and problems in terms of concrete quality and strength do not occur. When the pair of base members 21 and 22 are installed, the base members 21 and 22 are arranged in parallel to the planned installation area with a predetermined interval.

  The horizontal connecting members 23, 24, 25 are concrete block materials having fitting recesses 35 fitted to the upper flat portions and stepped portions of the base members 21, 22 at both ends, and these horizontal connecting members 23-25 are rectangular. It is a block body having an upper flat surface portion as a facility mounting surface, and has a horizontally long substantially T-shape when viewed from the side. In the upper plane part of the horizontal connection members 23-25, it constructs so that a horizontal surface may be obtained. The order in which the horizontal connecting members 23 to 25 are arranged by the base members 21 and 22 is appropriately determined according to the equipment and equipment to be installed, and is selected according to the position of the rail member 12 as described later. In the horizontal connecting member 23, one rail member 12 is disposed in the central portion, in the horizontal connecting member 24, a pair of rail members 12 are disposed apart from the central portion, and in the horizontal connecting member 25, one rail member is disposed. 12 is disposed such that the longitudinal direction of the member is the extending direction. A block-shaped base body 11 and an outdoor device (not shown) can be fixed by inserting a bolt head or nut into the rail member 12 and fastening the bolt or nut to a leg portion of the outdoor device.

  In this embodiment, the base body 11 is configured by combining concrete blocks. However, a single or a pair of concrete bricks themselves can be used as the base body, and the base body forms the foundation of an outdoor device. Such a pedestal concrete member may have other structures.

  In general, four connecting rods 13 extending from the base body 11 to the ground are attached to the base body 11 having such a structure in such a manner that the pair of base members 21 and 22 are inserted. The connecting rod 13 is a screw rod, for example, and has a structure in which a screw groove is formed on the outside. The connecting rod 13 is attached to the base body 11 by inserting the base members 21 and 22 of the base body 11 through the through holes 26 shown in FIG. A lift bolt 27, which will be described later, can be attached, and the workability is greatly improved by attaching the base body 11 to the connecting rod 13 via the lift bolt 27 having a flange formed on the lower side. The four connecting rods 13 have a length of about 20 cm to 140 cm, for example, and an embedded plate 14 is attached to the lower end portion. In the present embodiment, four connecting rods 13 that are underground connecting members are disposed. However, for example, two or three connecting rods may be used, and a plurality of four or more connecting rods may be used. In addition, the underground coupling member of the present invention is not limited to the screw rod, and any member such as a simple column or rail can be used as long as it is fixed to the base body 11 and fixed to the embedded plate 14. However, it may be formed by bending a part of the embedded plate 14 or may be a member such as a wire.

  The buried plate 14 is made of a rectangular stainless steel material, is buried in the ground at a depth in the range of 10 cm to 90 cm from the ground surface, and functions as a resistance plate when vibration is applied. The buried plate 14 is fixed to the end of the connecting rod 13 in the vicinity of the edge. This is configured such that a screw hole is provided at a position corresponding to the connecting rod 13 of the embedded plate 14, the connecting rod 13 is screwed into the screw hole, and a nut 32 is attached to a portion protruding to the opposite side of the embedded plate 14. Is done. The burying plate 14 has a rectangular shape reflecting the shape of the base body 11, but may have other shapes. For example, when the foundation of the house is overhanging under the eaves or the like, the embedded plate 14 may be arranged in a shape that avoids the overhanging foundation, for example, an L shape or a U shape. Further, the embedded plate 14 is not limited to a single plate, and a plurality of plates may be used in combination. As shown in FIG. 2, the soil 36 is actually filled between the buried plate 14 and the base body 11.

  Although the buried plate 14 may be directly buried in the ground as it is, the mortar layer 31 may be formed on the upper side of the buried plate 14 or on the lower side as shown in FIG. By forming the mortar layer 31, the seismic strength is greatly improved. An anchor bolt can be further provided on the embedded plate 14 itself. For the buried plate 14 itself, for example, a stainless steel material is selected from the relationship of corrosion resistance, but a structure in which mortar is combined with a composite material such as FRP or a mesh plate may be used.

  Next, with reference to FIG. 3 thru | or FIG. 7, the construction method of the earthquake-resistant base apparatus 10 of this embodiment is demonstrated. First, as shown in FIG. 3, the ground 1 in the planned construction area of the earthquake-resistant base device 10 is dug to form a rectangular hole 2 along the planar shape of the base. The depth of the hole 2 is, for example, about 10 cm to 140 cm, and preferably about 20 cm to 80 cm. The depth of the hole 2 can be changed according to the size and weight of the outdoor equipment to be installed.

  Next, a mortar is cast on the bottom surface of the hole 2 to form a mortar layer 31, and the connecting rod 13 is already fixed to the periphery of the buried plate 14 made of a stainless steel plate or other metal plate with a bolt 32. In this state, before the mortar layer 31 is dried and solidified, the mortar layer 31 and the bottom surface of the buried plate 14 are joined. The length of the connecting rod 13 should just be the height which protrudes about the height of the base main bodies 21 and 22 from the ground surface 1 when the burying board 14 is installed. As shown in FIG. 4, for example, the solidification of the mortar layer 31 is awaited with the structure in which the plurality of connecting rods 13 rise from the embedded plate 14 substantially vertically.

  Subsequently, the soil 36 is filled so as to fill the hole 2 on the buried plate 14. At this time, the soil 36 is embedded up to the level of the ground surface 1 or is embedded so as to form a mortar layer 37 on the surface portion as shown in FIG. By forming the mortar layer 37 on the surface portion, a more stable foundation can be created as compared with the case where the soil 36 is simply filled.

  After the mortar layer 37 is formed on the surface portion, the lift bolt 27 is attached to the upper end portion of the connecting rod 13. The lift bolt 27 is a cylindrical bolt whose inner surface is screwed with the outer periphery of the connecting rod 13, and a hook-like portion extending radially outward is formed on the bottom surface side. Even during curing or in a relatively soft state, the concrete block can be reliably supported while being placed on the bowl-shaped portion of the lift bolt 27. While the lift bolt 27 is rotated with respect to the connecting rod 13 that is a screw rod, the level of the hook-shaped portion of the lift bolt 27 can be finely adjusted. As shown in FIG. A pair of base members 21 and 22 are attached while being placed, and when such base members 21 and 22 are disposed on the ground surface, the level of the base members 21 and 22 can be raised while rotating the lift bolt 27. . Accordingly, the horizontal arrangement of the base members 21 and 22 can be proceeded very smoothly, and the working efficiency thereof is much higher than that of a concrete block for foundations in the past.

  When such a pair of base members 21 and 22 is attached, as shown in FIG. 7, a base body for supporting predetermined equipment is configured by connecting horizontal connecting members 23 to 25. After the horizontal connecting members 23 to 25 are coupled to the pair of base members 21 and 22 in this manner, the rail heads 12 formed on the upper surfaces of the horizontal connecting members 23 to 25 are not illustrated but are bolt heads. Or a nut is inserted and the leg of an outdoor apparatus is fixed to the said earthquake-resistant base apparatus reliably by fastening the volt | bolt etc.

  According to the seismic type base apparatus of the present embodiment having the above-described configuration, since the embedded plate 14 connected by the connecting rod 13 is arranged at the lower part of the base body 11, external forces such as earthquakes can be applied to outdoor equipment and Even when the base body 11 is joined, it is possible to prevent the tilting or collapsing. In an experiment conducted by the present inventors, a temporary outdoor device composed of a 600 kg sandbag was installed on the base device of the present invention, and the base device itself was pressurized in a horizontal direction by a forklift at a height of about 50 cm. As a result of measuring the inclination, the base body lifted up to about 20 mm or less up to about 3 to 6.7 KN (kilonewtons), and in terms of seismic intensity, it was stable horizontally up to about 1 G. It has been demonstrated that the equipment can be supported.

  FIG. 8 shows a seismic base apparatus according to the second embodiment. The seismic base apparatus shown in FIG. 8 has a single rectangular concrete block 41 as a base body, and an apparatus formed on the upper surface thereof. Outdoor equipment is installed through a rail member 50 that functions as a connecting member. The concrete block 41 is provided with a lift bolt 43 that is inserted into the insertion hole 42, and the lift bolt 43 is screwed into a full screw bolt 44 that is an underground connecting member. The lift bolt 43 is positioned by a nut 48 that is also screwed to the full screw bolt 44 when fixed. The full screw bolt 44 is configured such that a buried plate 45 is attached using nuts 47 and 46 at the lower end side thereof. These nuts 46, 47, 48 are each provided with a washer 49 to prevent loosening.

  Such a concrete block 41 is connected to an embedded plate 45 through a full screw bolt 44, embedded in a hole 52 dug from the ground surface portion 51, and between the concrete block 41 and the embedded plate 45. The space is filled with fillers such as soil and mortar. As in the second embodiment, the concrete block 41 is not configured by combining a plurality of blocks, but is only one basic member, but is provided with an insertion hole 42 through which the concrete block 41 is inserted. A similar embedded plate 45 can be embedded to improve the seismic strength.

  In the above-described embodiment, an example in which the base body of the earthquake-resistant base device is a rectangular body has been described. However, the base body of the earthquake-resistant base device of the present invention is not limited thereto, and a pair of concrete blocks are separated from each other. It can also be applied to the types of main bodies that are arranged in a line. Further, although the embedded plates 14 and 45 have been described as flat plate materials, in the earthquake-resistant base device of the present invention, a curved embedded plate such as an outer shape plate material or a kamaboko shape having undulating irregularities may be arranged. Is possible.

  FIG. 9 shows an earthquake-resistant base device according to the third embodiment. The base body is a concrete block 61 having a substantially rectangular shape, and outdoor equipment is installed via a linear rail member 62 that functions as a equipment connecting member formed on the upper surface of the concrete block 61. The concrete block 61 is shaped to have an opening 63 that passes through the inside of the frame in two locations in the vertical direction, and is connected to the through-holes 64 formed in the middle of the four corners and the long side of the concrete block 61 with underground connecting members. A certain whole screw bolt 65 is inserted respectively.

  An underground block 66 made of concrete and having a threaded portion that engages with the entire screw bolt 65 is attached to the lower end portion of the entire screw bolt 65. When embedding the underground block 66, a groove reflecting the size of the concrete block 61 is formed at a predetermined depth of about 20 to 80 cm, and six independent blocks are arranged on the bottom surface of the groove. Before attaching the underground block 66 fixed to the lower end of the whole screw bolt 65 to the concrete block 61, the concrete material 67 is connected so that the underground blocks 66 are connected to each other in a state where the whole screw bolt 65 is extended upward. An embedded plate 68 made of the underground block 66 and the concrete material 67 is formed by placing the substrate with a predetermined thickness. The soil is returned in such a manner that the buried plate 68 is buried in the ground, and the through holes 64 of the concrete block 61 are inserted into the upper ends of the six full screw bolts 65 protruding from the flat ground, and the upper ends of the full screw bolts 65 are inserted. Is fixed with a nut, and the seismic base device of the present embodiment is installed.

  In such an earthquake-resistant base device of the third embodiment, a concrete base can be formed in a relatively narrow portion from the shape of the concrete block 61, and the buried plate 68 itself is also an underground block 66 and a concrete material 67. Therefore, it is possible to construct according to the underground conditions. That is, depending on the installation position of the base device, it is necessary to avoid the existing piping etc. in the ground, but in the case of the buried plate made of a metal plate, it is necessary to process the buried plate itself that is a metal, in this embodiment Since the buried plate 68 is formed by the combination of the underground block 66 and the concrete material 67, the buried plate 68 can be laid out relatively freely and can be constructed flexibly. Moreover, although it is necessary to consider the problem of corrosion and the inconvenience of construction work due to weight in the buried plate made of a metal plate, the earthquake-resistant base device of the present embodiment can solve these problems.

  In the present embodiment, the shape of the concrete block 61 is rectangular, but other shapes can also be used, and the number of all screw bolts 65 and underground blocks 66 that are underground connection members is not particularly limited, and is arbitrary. The number of underground blocks 66 can also be arbitrarily large. The buried plate 68 constituted by the combination of the underground block 66 and the concrete material 67 is not necessarily flat, and may be partially shaped like a staircase if integrated.
