Description

  The present invention relates to a concrete foundation for an electric water heater used when a tank unit of an electric water heater is installed outdoors.

It is common for an electric water heater to install a part of equipment such as a tank unit outdoors. Thus, when installing the tank unit of an electric water heater etc. outdoors, the foundation which can endure the weight of a tank unit etc. is needed.

If the tank unit or the like is installed with sufficient strength such as concrete and a horizontal place can be secured, it may be placed directly on the tank unit and fixed with an anchor or the like.

However, when installing on the ground outdoors, a foundation is required. In such a case, there are a method of placing concrete to form a foundation and a method of arranging concrete blocks as a foundation.

  Thus, when making a foundation, it is important to finish the surface of the foundation horizontally. This requires the tank unit to be installed horizontally, so that the foundation surface must be finished as horizontally as possible.

  However, the method of placing concrete locally has the problem that it takes time to finish horizontally. Furthermore, there is a problem that the tank unit cannot be installed until the concrete is completely cured.

  And for earthquake countermeasures, it is necessary to increase the thickness of the concrete foundation sufficiently to gain weight, and further, it takes time and effort to embed an anchor for fixing the tank unit to prevent falling.

  In addition, when the concrete blocks are simply arranged side by side, there is a risk of overturning during an earthquake, and there is a problem with earthquake resistance.

  An object of the present invention is to provide a concrete foundation for an electric water heater that eliminates the conventional construction labor and has an effect of preventing the fall even when an earthquake occurs.

The concrete foundation for electric water heater of the present invention includes two base blocks for mounting a tank unit of the electric water heater, and two rails for mounting the two base blocks and connecting them in parallel at a predetermined interval. And two pile concrete pillars, the upper part of which is fixed to the rail and buried in the soil, the rail is embedded on the upper surface of the base block, and the tank unit is attached to the tank unit by mounting bolts movable in the rail. Fixed to the base block, the base block is fixed to the rail by means of mounting bolts movable in the two rails, the two rails are arranged in parallel, and each of the pile concrete pillars by a pile anchor It is characterized by being fixed to.

  The cross-sectional shape of the rails embedded in the two rails and the base block is substantially U-shaped, and both upper portions of the U-shape are bent inwardly in a hook shape. The bolt and the mounting bolt of the base block are preferably provided with a plate inserted from the side so as to be movable in the rail.

  Moreover, it is preferable that the said pile concrete pillar has a hexagonal cross section, has a flared shape, and has a collar portion.

The concrete foundation for electric water heater of the present invention includes two base blocks for mounting a tank unit of the electric water heater, and two rails for mounting the two base blocks and connecting them in parallel at a predetermined interval.

  Next, the procedure for installing the concrete foundation 1 for electric water heater of the present invention on the ground will be described with reference to FIG.

  First, the ground is excavated larger than the range where the concrete foundation 1 for electric water heaters is installed. The depth is assumed to be a depth considering the thickness of the rail 3 and crushed stones and cement laid under the rail 3 as a whole.

And the place which installs the two pile concrete pillars 4 is made into the depth which considered the height of the pile concrete pillar 4, and the crushed stone and cement laid under it, respectively, and excavates one step deeper than the circumference. In this way, when excavation is completed, the crushed stone is spread and leveled, and then the cement is further spread and flattened to some extent.

  Next, the two rails 3 and the two base blocks 2 are fixed on a flat place. First, the two rails 2 are arranged in parallel at the same interval as the interval between the two through holes 8 of the base block 2, and two plates 22 attached to the bolts 21 on the two rails 3, respectively, from the side of the rail 3. Insert and set in place.

Then, two base blocks 2 are placed in parallel on the two rails 3. At this time, the bolt 21 is inserted into the through hole 8 of the base block 2. In this way, the two rails 3 and the two base blocks 2 are combined in a well shape. Thereafter, the rail 3 and the base block 2 are fixed by the above-described method using the washer 23, the sub-washer 24, and the nut 25 of the mounting bolt 5. At this time, the interval between the two base blocks is adjusted in accordance with the interval between the legs 15 of the tank unit 14 of the electric water heater to be placed on top.

  Next, the pile concrete pillar 4 is set in a place excavated one step deeper. And the rail 3 which fixed the above-mentioned base block 2 is mounted on it. At this time, the hole opened on the bottom surface of the rail 3 is aligned with the bolt receiver 12 on the top surface of the pile concrete 4. And the said rail 3 and the said pile concrete pillar 4 are fixed by the above-mentioned method using the pile anchor 13. FIG.

  When the assembly of the electric water heater concrete foundation 1 is completed in this manner, the periphery of the pile concrete 4 is then backfilled with concrete or the like. Further, the periphery of the rail 3 is laid on the same height as the surrounding ground using crushed stone or the like. This completes the installation of the concrete foundation 1 for an electric water heater.

  After that, with the plate 42 attached to the bolt 41 to the rail 7 of the base block 2, the plate 42 is inserted from the side of the rail 3 and the bolt 41 is installed on the legs of the tank unit 14 of the electric water heater. Set according to the position of 15 holes. And the tank unit 14 of an electric water heater is mounted on the base block 2, and the leg 15 is fixed with the attachment bolt 5 by the method as mentioned above. Thus, the state as shown in FIG. 5 is obtained, and all the processes are completed.

  Thus, the concrete foundation for an electric water heater of the present invention can be easily leveled during installation, has better workability, and can shorten the installation time. In addition, by embedding pile concrete columns in the soil, it became possible to improve earthquake resistance.

As a result, simpler and faster installation is possible, and safety can be improved at low cost.
