  Recently, hot water storage type hot water heaters are of high function with a bath automatic hot water function and a hot water heating function, and a large capacity type which does not have to worry about hot water.

  In addition, because of the demand for convenience, there is an increasing trend in high-rise apartment buildings in urban areas, and hot water storage water heaters installed in this area are required to have sufficient strength against earthquakes in high-rise areas. Yes.

  In general, piping for the automatic hot water hot water function and hot water heating function is placed under the floor, so the piping connection part of the hot water heater is located on the installation leg mounting surface at the bottom of the hot water heater body. Piping work will be done in a space with installation legs.

  Especially in high-rise housings, improvement of installation workability is required. In addition to simplifying anchor bolt fixing work to the installation legs as in the conventional configuration, there is a demand for improvement in workability of piping work and wastewater treatment work. The weight of is getting bigger.

  However, in the above-described conventional configuration, the front installation leg and the rear installation leg are configured by assembling two parts of the floor grounding part and the installation leg column by welding or the like, and the floor grounding part and the installation leg column are both parallel. Since the floor grounding section with multiple boxes has a layout that is oriented in the same direction, if a strong earthquake impact is generated at a certain angle with respect to the direction of the floor grounding section, The cross section of the installation leg is deformed so as to fold a parallelogram, and the place where the floor grounding part and the installation leg column are fixed is damaged due to stress concentration.

  In order to improve the seismic strength corresponding to this, it is necessary to increase the number of installation legs or make the installation pedestals thicker and larger, which reduces the piping space on the floor surface and deteriorates the workability of the piping work. It had the problem of end.

  The present invention solves the problem of improving both the seismic strength of a hot water storage type hot water heater and the improvement of installation workability, and increases the number of installation legs of the hot water type hot water heater or thickens the installation pillar. In addition, since the seismic strength can be greatly improved, it is possible not only to install hot water storage water heaters in high-rise housing, but also to increase the installation legs to ensure the conventional strength, so piping work It is also possible to further improve the performance.

  In order to achieve the above object, the mounting leg of the present invention has a device fixing surface for fixing a device on the top, an anchor bolt fastening surface disposed on the bottom so as to face the device fixing surface, and a front side. And an anchor bolt fastening surface and the device fixing surface are integrated with each other by bending the mounting leg column surface from the installation leg column surface. .

  According to the above invention, even if there is a stronger earthquake impact than before, since the two installation pedestal surfaces are angled, deformation that folds the parallelogram cannot occur, and the stress is distributed. In addition, since the entire installation leg is originally integral, there is no stress concentration area, and the seismic strength is greatly improved. That is, installation in a high-rise house can be made possible.

  In addition, since the seismic strength is higher than before, the installation leg height can be greatly increased, and all the installation legs including the installation legs on the rear can be easily operated from the front for anchor bolt fixing work. Space that can be secured can be secured, and the workability is far superior to the conventional technology. In addition, there is a work space even when there are many pipes for automatic hot water hot water function and hot water heating function and waste water treatment in the piping space on the floor at the bottom of the tank like a high-function type hot water storage type water heater. Since it is large, workability of piping work and wastewater treatment work is improved.

  Furthermore, the anchor bolt fixing hole may be arranged at the center of gravity position of the anchor bolt fastening surface, and the seismic strength is further improved, and since the front has an open trapezoidal shape, there is room in the tool handling space. Even if there is no special tool for narrow space, it can be said that the work can be performed with a general large fastening tool (wrench or monkey) and the workability is excellent.

  Even if the installation leg of the present invention has a stronger earthquake impact than before, since the two installation leg column surfaces are angled, deformation that folds a parallelogram cannot occur, and the stress is dispersed. In addition, since the entire installation leg is originally integral, there is no part where stress is concentrated and the seismic strength is greatly improved. That is, installation in a high-rise house can be made possible.

  In addition, since the seismic strength is higher than before, the installation leg height can be greatly increased, and all the installation legs including the installation legs on the rear can be easily operated from the front for anchor bolt fixing work. Space that can be secured can be secured, and the workability is far superior to the conventional technology. In addition, there is a work space even when there are many pipes for automatic hot water hot water function and hot water heating function and waste water treatment in the piping space on the floor at the bottom of the tank like a high-function type hot water storage type water heater. Since it is large, workability of piping work and wastewater treatment work is improved.

Furthermore, the anchor bolt fixing hole may be arranged at the center of gravity position of the anchor bolt fastening surface, and the seismic strength is further improved, and since the front has an open trapezoidal shape, there is room in the tool handling space. Even if there is no special tool for narrow space, it can be said that the work can be performed with a general large fastening tool (wrench or monkey) and the workability is excellent.

To do .

  As a result, even if there is a stronger earthquake impact than before, since the two mounting pedestal surfaces are angled, the stress is dispersed and deformed by the fact that the deformation that folds the parallelogram does not occur. Not only is it difficult, but the entire installation leg is originally integrated, so there is no stress concentration and the strength against breakage is greatly improved.

  In addition, since the seismic strength is higher than the conventional one, the installation leg height can be greatly increased, and the anchor bolt fixing work can be secured from the front, and the workability can be secured. As far as conventional technology is concerned.

If the trapezoidal shape of the rear surface of the installation pedestal is small at the top and large at the bottom, for example, the area for fixing the installation legs at the bottom of the hot water storage water heater is small. A large piping space for the beam function and the hot water heating function can be secured, and the workability of the piping work and the wastewater treatment work is improved. In addition, since the anchor bolt fastening surface on the floor surface is enlarged, the space for the tool is increased, and the workability by the fastening tool (wrench or monkey) is also improved.

  Furthermore, the structure according to the present invention increases the installation leg height to further improve the piping workability, and even if the tank fixing surface is reduced, the seismic strength is not impaired, and the planar development shape of the metal material is reduced. Since it does not become large, not only can resources be saved, but also rational manufacturing can be realized.
