TECHNICAL FIELD OF THE INVENTION
The present invention relates to a foundation unit for installing an energy system.
[0002]
[Prior art]
When a hot water storage tank such as an electric water heater is installed in a house, the hot water storage tank weighs 400 kg to 500 kg when full, so foundation work is performed using concrete or the like that can withstand heavy weight. This foundation work requires excavating the ground at the installation site, digging a hole, pouring concrete into the excavation hole, and curing it. I was
[0003]
In order to shorten this construction period, it is known to use a prefabricated block manufactured in a factory in advance (for example, see Patent Document 1). According to this method, the work of pouring concrete and curing on site is unnecessary, and the foundation work is completed only by placing the prefabricated block in the hole dug in the ground.

JP-A-11-50470
[Problems to be solved by the invention]
By the way, if the concrete is directly poured into the excavation hole without using the prefabricated block as in the conventional case, the concrete is fixed to the ground in the process of curing the concrete. However, when the prefabricated block is used, the prefabricated block is merely placed in the excavation hole, so that the anchorage to the ground is weak. For this reason, there is a risk that the prefabricated block may be tilted due to an earthquake or the like.
[0006]
The present invention solves the above problems, and is an energy system installation base unit that can be manufactured in a factory or the like in advance, can be easily installed on site, and can exhibit strong anchoring power to the ground. The purpose is to provide.

[Means for Solving the Problems]
According to an aspect of the present invention, there is provided an energy system installation base unit comprising: a base having an upper surface on which an energy system is installed; and at least one auxiliary member fixed to the base. Has at least one protrusion protruding laterally from the base at a position lower than the upper surface of the base, and at least the protrusion is buried in the ground.
[0008]
The energy system installation base unit according to the present invention exerts a strong anchoring force when the protruding portion is buried in the ground, so that there is no danger of tilting due to an impact such as an earthquake. In addition, this basic unit can be manufactured in a factory or the like in advance, and construction on site can be easily performed in a short period of time.
[0009]
In a preferred aspect, the auxiliary member is fixed to a side surface of the base. In this aspect, it is also possible to arrange only the base portion in the excavation hole before assembling the foundation unit, and to attach an auxiliary member after that, which increases the degree of freedom of construction.
[0010]
In a preferred aspect, the auxiliary member is entirely flat and fixed to the bottom of the base, and at least a part of the auxiliary member projects laterally from the base to form the protrusion. I have. In this embodiment, since the auxiliary member has a simple flat plate shape, it is not necessary to perform processing such as bending in manufacturing, and the manufacturing becomes easy.
[0011]
In a preferred aspect, at least one pipe for an energy system is provided inside the base, and each end of the pipe is opened on the upper surface of the base. In this aspect, the piping work of the energy system can be easily performed by using the piping provided inside the base portion. Furthermore, since the piping is not exposed to the outside, the appearance is excellent, and deterioration of the piping due to ultraviolet rays or the like can be prevented. In particular, when the energy system is a cogeneration system including a power generation facility or a water heater, it is important to keep warm water sent from the power generation facility or the water heater. Thus, heat radiation from the piping is prevented, and freezing of water flowing in the piping can be prevented. It is more effective if the pipe is covered with a heat insulating material.
