Description

  The present invention relates to a foundation structure using a concrete block that constitutes a foundation for supporting an outdoor facility when the outdoor facility of a building is installed on the ground.

    When installing equipment such as a water heater, an outdoor unit, and a boiler on the outdoor ground, it is common to use a concrete foundation as a gantry for supporting them.

  For example, after excavating a predetermined area of the ground to be installed, rubble is spread and leveled there, and so-called discarded concrete is placed. Make a formwork by placing reinforcing bars on this discarded concrete and arranging reinforcing bars. There is a method in which concrete is laid and used as the basis for installing equipment. (For example, Patent Document 1)

  However, such a method has a problem that it takes a construction period for placing concrete and requires a construction period until the equipment is installed.

  For this reason, after excavating a predetermined range of the ground to be installed, laying rubble there, leveling it, and installing it using a precast concrete block may be performed.

Japanese Patent Application Laid-Open No. 11-181795

  However, when the conventional precast concrete block as described above is used, the weight of the precast concrete block itself exceeds 200 kg, and there is a problem that it is difficult to carry and install by human power.

  Therefore, it will be transported by machine, but in general, the installed equipment is often installed in empty gaps, gardens, etc. of the site of the house, using machines that require an operating place There was a problem that it was difficult to transport and install precast concrete blocks by the side of a narrow building.

  In view of the above-described problems of the prior art, an object of the present invention is to provide a foundation structure using a concrete block that is inexpensive, has a short construction period, and is easily transported and installed by human power.

  The feature of the invention described in claim 1 for solving the conventional problems as described above and achieving the intended purpose is a foundation structure for supporting the equipment on the ground when installing the equipment for buildings. A bottom plate composed of a pair of left and right bottom plate end members formed of a flat plate-like precast concrete block and a bottom plate connecting member fitted therebetween, is disposed on the equipment installation ground, and the flat plate-like precast is placed on the bottom plate. An anchor in which a top plate composed of a pair of front and rear upper plate end members formed of a concrete block and an upper plate connecting member fitted between the upper plate end member and a bottom plate end member is arranged so as to be laid on the bottom plate, and is embedded in the bottom plate A bolt is tightened through a connection hole provided in the upper plate to the nut, the upper plate and the bottom plate are integrated, and an anchor bolt inserted into the ground through the fixing hole provided in the upper plate and the bottom plate is inserted with the nut. The underlying structure by fit with the equipment installed ground fixed concrete block.

  According to a second aspect of the present invention, in addition to the structure of the first aspect, the bottom plate is formed in a flange shape from the bottom of the left and right bottom plate end members provided with the anchor nuts opened on the upper surface to the bottom plate connecting member side. A connecting member supporting piece that protrudes; the bottom plate connecting member includes an end member supporting piece that protrudes from the top to the left and right in the form of a flange; the end member engaging piece meshes with the connecting member supporting piece; A connecting member frame piece projecting in a flange shape from the upper part of the upper and lower upper plate end members including the connecting hole penetrating vertically to the upper plate connecting member side, and the upper plate connecting member from the lower part to the front and rear An end member support piece projecting in a flange shape is provided, and the connecting member frame piece meshes with the end member support piece.

  The foundation structure by the concrete block which concerns on this invention is a foundation structure which supports this equipment on the ground when installing the equipment for buildings, Comprising: A pair of right-and-left bottom-plate end members formed with the flat-shaped precast concrete block And a bottom plate composed of a bottom plate connecting member fitted between them, is disposed on the equipment installation ground, and a pair of front and rear upper plate end members formed by a flat precast concrete block on the bottom plate and fitted therebetween. An upper plate composed of an upper plate connecting member to be joined is arranged so as to be installed on the bottom plate end member, and an anchor nut embedded in the bottom plate is tightened with a bolt through a connecting hole provided in the upper plate, And the bottom plate are integrated, and the anchor bolt inserted through the fixing hole provided in the top plate and the bottom plate to the ground is tightened with a nut and fixed to the installation ground. And by, one precast concrete blocks are possible to transport by human power even in narrow spaces lightweight, also it requires only a short easy construction period construction method.

  Further, in the present invention, the bottom plate includes a connecting member support piece projecting in a flange shape from the lower part of the left and right bottom plate end members toward the bottom plate connecting member, and the bottom plate connecting member has a flange shape from the top to the left and right. The end member frame piece is engaged with the connecting member supporting piece, and the upper plate is flanged from the upper part of the upper and lower upper plate end members to the upper plate connecting member side. An extended connecting member frame is provided, and the upper plate connecting member is provided with an end member supporting piece that protrudes in the form of a flange from the bottom to the front and rear, and the connecting member frame is engaged with the end member supporting piece. Thus, when tightened with the bolt, the connecting member support piece presses the end member support piece upward, and the connection member support piece presses the end member support piece downward, and the bottom plate connection member and the upper plate connection When it comes to retaining members The bottom plate and the upper plate is reliably integrated even with a small number of bolts.
