Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basic concrete plate used for supporting a tank such as a septic tank, a tank supporting facility, and a method of installing the same.

[0002]

2. Description of the Related Art For example, when a septic tank is installed underground,
Conventionally, a construction machine for excavation is used to dig a hole in the ground according to the size of a septic tank, and a hole having a predetermined size and depth is excavated, and then a fresh concrete placing work is performed. In concrete pouring work, first, crushed stones are laid on the bottom of the excavated hole, then a formwork is installed, and then reinforcing bars are laid in a grid pattern. The laid rebar is tied at the intersection. After this, ready-mixed concrete is placed in the formwork.

After completion of the pouring of the ready-mixed concrete, a necessary curing period is taken, after which a septic tank is installed on the basic concrete, and then the surrounding area is backfilled.

One of the problems of the above-mentioned conventional construction method is that the fresh concrete is directly affected by the outside temperature whose temperature cannot be controlled, and the concrete strength fluctuates. For example, in winter, the strength of raw concrete deteriorates due to freezing of fresh concrete.

Another problem with the conventional method is that it is difficult to uniformly perform the work of laying and bundling because the work of laying and bundling the reinforcing bars is performed on site, and that the holes in the soil wall are exposed. Since it is necessary to lay the reinforcing bars inside and to bind them together, the reinforcing bars are likely to become dirty and rusted. These cause a decrease in strength of the basic concrete.

Still another problem with the conventional method is that a curing period of at least 72 hours must be secured in order to secure strength. This means that the excavated hole must be left for several days, which lengthens the construction period and is dangerous not only for the workers but also for the residents around the construction site.

Further, in the conventional construction method as well, a method of separately manufacturing the basic concrete portion before construction has been considered, but the standard construction has a single-piece structure without connecting portions. As a result, in proportion to the increase in the size of the tank supporting equipment, much cost and labor were required for the transportation and installation work of the foundation concrete part, which was a great economic disadvantage. At the same time, since it is a standard product with a single sheet structure, it cannot be applied to septic tanks having various sizes, the usage conditions are limited, and the practicality is poor.

As another conventional technique, there is known a technique of forming a basic concrete portion by connecting a plurality of basic concrete plates with connecting metal fittings. However, in a structure in which a plurality of foundation concrete plates are connected by connecting metal fittings, mechanical strength is insufficient because gaps and rocking occur in the connecting portions of the connecting metal fittings.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to provide a foundation capable of reducing the labor required for the transportation and installation work of the materials related to the construction of the foundation concrete part, which is the base of the equipment, even if the tank supporting equipment becomes large in size. It is to provide a concrete board, a tank supporting equipment using the basic concrete board, and an installation method thereof.

Another object of the present invention is to provide a basic concrete plate which can be adapted to tanks having various sizes, a tank supporting equipment using the basic concrete plate, and a method of installing the same.

Another object of the present invention is to control the temperature of ready-mixed concrete constituting a foundation concrete plate without being affected by fluctuations in air temperature, and therefore to prevent strength deterioration due to poor temperature control. To provide a high-quality base concrete plate, a tank support facility using this base concrete plate, and an installation method thereof.

Still another object of the present invention is to provide a basic concrete which enables uniform laying and connection of the reinforcing bar, does not cause dirt and rust on the reinforcing bar, and therefore can form a basic concrete portion having a predetermined strength. To provide a board, a tank supporting equipment using the foundation concrete board, and a method of installing the tank supporting equipment.

Yet another object of the present invention is to provide a foundation concrete plate which does not require a curing period for the foundation concrete portion on site and is effective for shortening the construction period and preventing danger, and a tank using this foundation concrete plate. It is to provide a supporting facility and a method of installing the supporting facility.

[0014]

In order to solve the above-mentioned problems, the basic concrete board according to the present invention includes a concrete base and a reinforcing bar. The concrete base is a flat plate having a predetermined thickness, the reinforcing bars are provided inside the concrete base, and a part of the reinforcing bar projects from at least one side surface of the basic concrete plate. The basic concrete board is manufactured in advance in a factory.

As described above, in the basic concrete plate according to the present invention, since the reinforcing bars are provided inside the concrete substrate, the mechanical reinforcing effect of the reinforcing bars can be obtained, and the basic concrete plate having high mechanical strength can be obtained. .

Moreover, since the reinforcing bar partially projects from at least one side surface of the basic concrete plate, the projecting portion is used as a connecting projecting portion, and the plurality of basic concrete plates have at least one connecting projecting portion. Can be combined on the sides. Therefore, the individual concrete foundation plates themselves can be kept small, and the labor required for transportation and installation work can be reduced.

Further, since the basic concrete plate according to the present invention is manufactured in advance in a factory, the temperature control of the ready-mixed concrete forming the basic concrete plate can be surely executed by the facility controlled by the factory. . That is, it is possible to obtain a high-quality basic concrete plate by avoiding the influence of the fluctuation of the outside temperature in the outdoor laying work, avoiding the strength deterioration due to poor temperature control.

Further, the laying of the reinforcing bars and the setting of the connection and the connecting projections can be carried out in the factory, so that the reinforcing bars can be laid evenly and reliably connected. Since welding can also be used as a connecting means, the mechanical strength of the reinforcing bar formation can be increased. Similarly, it is possible to extend the reinforcing bars functioning as the connecting protrusions and to set the dimensions of the reinforcing bars so that the processing step can be surely executed. Moreover, since these operations can be performed in a factory with a good environment, the reinforcing bars and the connecting projections will not be soiled or rusted. Therefore, a basic concrete plate having a predetermined strength can be formed.

The above-mentioned foundation concrete plate is used for tank supporting equipment. The tank support facility includes a foundation concrete part, a pedestal, and a tank. The basic concrete portion is provided by connecting a plurality of the basic concrete plates with the projecting portion. The pedestal is provided on the basic concrete portion. The tank is

Here, the basic concrete plate according to the present invention includes a concrete base and a reinforcing bar, and since a part of the reinforcing bar projects from at least one side surface of the basic concrete plate, by connecting the projecting portions, It is possible to reliably and easily connect a plurality of foundation concrete plates. Therefore, even if the tank supporting equipment becomes large in size, the labor required for the installation work of the foundation concrete portion as the base can be reduced to the labor required for handling the smaller foundation concrete plate. Then, as described above, by providing the foundation concrete plate with the connectable structure, the area of the foundation concrete portion can be easily adjusted at the installation site so as to match the individual tank dimensions. As a result, it can be widely used in tanks having various sizes, for example, septic tanks, and work efficiency can be improved and construction costs can be reduced.

Further, in the present invention, since a smaller basic concrete plate can be used instead of the standard concrete part having a one-piece structure, it is possible to reduce the weight of construction materials and facilitate transportation and operation. it can.

Further, since the basic concrete board according to the present invention is manufactured in advance in a factory, it is not necessary to put ready-mixed concrete on site.

The method for installing the tank support equipment according to the present invention includes a first step, a second step, and a third step. In the first step, a plurality of the basic concrete plates are manufactured in advance in a factory, and the projecting portions are opposed to each other and arranged on a grounded installation surface in the field. In the second step, the projecting portions are connected by a predetermined method in the gap between the foundation concrete plates, and are reinforced by the bridged concrete portion to form an integrated structure. In the third step, after the second step, the bridge is placed while avoiding the bridged concrete portion, and the tank is placed on it.

The foundation concrete plate has already been completed at the factory, and at the site, a plurality of foundation concrete plates are installed at the bottom of the hole dug in the ground with a size corresponding to the tank, and then installed. It suffices to connect opposite projecting portions between the respective foundation concrete plates and bridge the connecting portions with concrete. Therefore, the curing period, which is usually required for the basic concrete portion, becomes unnecessary, and the construction period can be shortened and danger can be prevented significantly.

In order to install the tank, a pedestal is installed while avoiding the bridged concrete portion related to the connection, and the tank is placed on it. Therefore, the load of the tank can be avoided from being directly applied to the bridged concrete portion, and the tank can be installed early.

More specific features and advantages of the present invention will be more specifically described with reference to the drawings.

FIG. 2 is a sectional view taken along line 2-2 shown in FIG. 1. Figure 3
FIG. 3 is a plan view of a layout structure of reinforcing bars included in the foundation concrete plates shown in FIGS. 1 and 2 and a connection.

The illustrated foundation concrete board is
It is manufactured in a factory. Inside the concrete substrate 11, the horizontal reinforcing bars 12 are arranged in the required number and pitch.
The vertical reinforcing bars 13 are arranged in a grid pattern, for example, and have a multilayer structure. Each intersection of the horizontal reinforcing bar 12 and the vertical reinforcing bar 13 is connected to each other. As the connecting means, welding or binding by a wire is usually used.

A part of the horizontal reinforcing bar 12 is extended in a predetermined direction and protrudes from at least one side surface of the concrete substrate 11 to form a connecting protrusion 15.

As described above, in the basic concrete plate according to the present invention, a part of the horizontal reinforcing bar 12 is extended in a predetermined direction and protrudes from at least one side surface of the concrete base body 11 to form the connecting projection 15. Therefore, it is possible to combine a plurality of foundation concrete plates with the connecting projection 15. Therefore, the individual foundation concrete plates themselves can be kept small, and the labor required for transportation and installation work can be reduced.

Moreover, since the basic concrete board according to the present invention is manufactured in advance in a factory, the temperature control of the ready-mixed concrete constituting the basic concrete board can be surely executed by the facility controlled by the factory. . That is, it is possible to obtain a high-quality basic concrete plate by avoiding the influence of the fluctuation of the outside temperature in the outdoor laying work, avoiding the strength deterioration due to poor temperature control.

The laying of the horizontal reinforcing bar 12 and the vertical reinforcing bar 13,
Since the connection 14 and the connecting protrusion 15 can be set in the factory, the horizontal reinforcing bars 12 and the vertical reinforcing bars 13 can be evenly laid and reliably connected. Welding can also be used as the means for the connection 14, so that the mechanical strength of the reinforcing bar formation can be increased. Similarly, the horizontal reinforcing bars 12 functioning as the connecting protrusions 15 can be extended and the dimensions of the horizontal reinforcing bars 12 can be set, and the processing step thereof can be executed reliably. Moreover, since these operations can be carried out in a factory with a good environment, the horizontal reinforcing bars 12, the vertical reinforcing bars 13 and the connecting projections 15 do not become dirty or rusted. Therefore, a basic concrete plate having a predetermined strength can be formed.

The numbers, pitches, and arrangement shapes of the horizontal reinforcing bars 12 and the vertical reinforcing bars 13 in FIGS. 1 to 3 are merely examples, and if the necessary strength as the reinforcing bars can be secured, the number may be larger or smaller than the illustrated quantity. The arrangement shape may not be a grid shape.

Similarly, the laminated structure of the reinforcing bars combined by the connection 14 is clearly shown as a double structure in FIG. 2, but the necessary strength as a reinforcing bar can be ensured and at least one of the concrete bases 11 can be secured. The number of overlaps may be at least as long as a part of the horizontal reinforcing bar 12 or the vertical reinforcing bar 13 can be projected from the side surface to form the connecting projection 15 that functions effectively.

FIG. 4 is a perspective view of the tank support equipment according to the present invention provided in the ground. FIG. 5 is a front view of the tank support facility shown in FIG. FIG. 6 corresponds to FIG. 4 or FIG.

The tank supporting equipment shown in FIGS. 4 to 7 has a crushed stone 3 laid on the bottom 21 of the hole 20 for leveling.
However, when the tank 40 is a septic tank, this is an example assuming a normal installation place. Therefore, there is no difference in the performance of the tank supporting equipment itself depending on whether the installation location is on the ground surface or in the ground. Similarly, crushed stone 30
Is to be laid for leveling and strengthening the ground, so when installing the tank support equipment according to the present invention in a strong place of the ground where there is no need to lay the crushed stone 30,
Not necessarily an essential component.

As described with reference to FIGS. 1 to 3, the basic concrete plate 10 used in the tank supporting device includes a concrete base and a reinforcing bar, and a part of the reinforcing bar is at least the basic concrete plate. Since it projects from one side surface, it is possible to reliably and easily connect the plurality of foundation concrete plates 10 by connecting the protruding portions 15. Therefore, even if the tank support equipment becomes large,
The labor required for the installation work of the foundation concrete part 17 which is the base is smaller than the basic concrete board 1
The labor required for handling 0 can be reduced. Then, as described above, by providing the connectable structure to the base concrete plate 10, the area of the base concrete portion 17 can be easily adjusted at the installation site so as to match the individual tank dimensions. As a result, it can be widely used in tanks having various sizes, for example, septic tanks, and work efficiency can be improved and construction costs can be reduced.

Further, in the present invention, since a smaller basic concrete plate 10 can be used instead of the standard concrete part 17 having a single-piece structure, the construction material can be successfully reduced in weight and can be easily transported. Becomes

Further, since the basic concrete board 10 according to the present invention is manufactured in advance in a factory, it is not necessary to put ready-mixed concrete on site. Moreover, the temperature control of the ready-mixed concrete forming the basic concrete board 10 can be surely executed by the facility controlled by the factory. Therefore, it is not affected by temperature fluctuations, avoids strength deterioration due to poor temperature control, and is a high-quality basic concrete board 1
0 can be realized.

Further, the laying and connection of the reinforcing bars, which are the internal structure of the basic concrete board 10, are also performed by the basic concrete board 10.
Since it can be performed in the factory at the same time as the manufacturing of, the reinforcing bars can be laid evenly and connected. Moreover, since welding or the like can be adopted as the connecting means, the mechanical strength of the reinforcing bar formation can be increased.
Since these operations can be carried out in a factory with a good environment, it is possible to form a basic concrete plate having a predetermined strength without causing stains and rust on the reinforcing bars.

Next, a method of installing the tank support device shown in FIGS. 4 to 7 will be described. FIG. 8: is a perspective view of the hole in which the foundation concrete board which concerns on this invention is installed.
When a tank such as a septic tank is buried in the ground using the above-mentioned basic concrete plate 10, as shown in FIG. 8, a hole 20 is dug at an installation site using an excavator or the like. Hole 20
Includes a bottom surface 21 and is usually formed to be slightly larger than a tank to be installed later in order to facilitate construction.

FIG. 9 is an exploded structural view showing a process of laying crushed stones on the bottom surface of the hole shown in FIG. 8 and installing a foundation concrete plate in combination. FIG. 10 is a perspective view showing a state in which the connecting protrusions are connected after the step shown in FIG. 9 is completed. FIG. 11 is a side view of FIG.

As shown in FIG. 9, a hole 20 dug in the ground
Crushed stones 30 are usually spread evenly on the bottom portion 21 of the ground for strengthening the ground. Although not shown, crushed stone 30
Mortar can be applied to the surface of the to form a highly level installation surface. Then, the foundation concrete plate 10
The connecting projections 15 are opposed to each other and are inserted as shown by an arrow Z, and are installed on the bottom portion 21 of the hole 20 as shown in FIGS. The basic concrete plate 10 is transported by a transport vehicle from the manufacturing plant. Then, it is installed on the bottom portion 21 of the hole 20 by using a crane truck or the like.

In the prior art, after the step of excavating the hole 20, the ready-mixed concrete placing work was performed. That is, first, crushed stones are spread over the bottom of the excavated hole, a formwork is installed, and the reinforcing bars are laid in a grid pattern. Next, the laid reinforcing bars are connected at intersections, and then ready-mixed concrete is placed in the formwork. Then, after the completion of the ready-mixed concrete placing work, a necessary concrete curing period is taken, after which a septic tank is installed on the basic concrete, and finally the surrounding work is backfilled.

On the other hand, in the basic concrete part 17 of the tank supporting equipment according to the present invention, the basic concrete plate 10 which is smaller than the conventional basic concrete is manufactured in advance in the factory and is transported to the installation site. It is made by combining them.

In terms of quality, the strength of the basic concrete plate 10 can be prevented from being deteriorated due to poor temperature control in outdoor work by the factory manufacturing, and the predetermined strength can be secured without causing the reinforcing bars to be soiled or rusted. In terms of size, because it is small, it is easy to carry and install, and the curing period required for the entire basic concrete on site is unnecessary,
A basic concrete board 10 that is effective for shortening the construction period and preventing danger is realized.

FIG. 12 is a perspective view showing a state in which, following the steps shown in FIGS. 10 and 11, concrete is replenished and bridged in the gap between two adjacent concrete foundation plates. FIG. 13 is a side view of FIG.

Referring to FIGS. 12 and 13, two adjacent concrete foundation plates 10 are integrated by reinforcing the connecting projection 15 connected to each other by the connection 14 with the bridge concrete part 16. It becomes a structure and forms the foundation concrete part 17.

The base concrete plate 10 is placed on the bottom surface 2 of the hole 20.
First, after installing on 1, the adjacent connecting concrete projections 10 in the two adjacent concrete concrete plates 10
As shown in FIGS. 10 and 11, they are connected by the connection 14, and then the remaining gap is filled with concrete,
The crosslinked concrete portion 16 is configured. The foundation concrete part 10 which was a separate entity is a bridge concrete part 16
By this, they are integrated to form the basic concrete portion 17. In this respect, since it is sufficient to pour ready-mixed concrete only into the cross-linked concrete portion 16, the curing period of concrete can be significantly shortened as compared with the conventional case. Further, it is possible to meet a predetermined standard as an integrated structure that meets the architectural standard under the administrative regulations, and there is no inconvenience in construction in terms of strength of the basic concrete portion 17.

FIG. 14 is an exploded structural view showing a step of installing a tank such as a septic tank on the basic concrete portion according to the present invention. In FIG. 14, the gantry 50 is installed on the foundation concrete portion 17 arranged inside the hole 20, and the tank 40 is placed on the gantry 50.

FIG. 15 is a perspective view showing a state after the tank is placed on the mount. The tank 40 is installed, for example,
This is executed using a crane vehicle or the like, and the area around the tank 40 is backfilled after installation.

Here, the basic concrete plate 10 has already been completed in the factory, and at the site, it is installed by the above-mentioned predetermined procedure, the bridge concrete part 16 is provided in the gap, and the basic concrete part 17 is formed. Next, the pedestal 50 may be provided on the foundation concrete portion 17, and the tank 40 may be placed on the pedestal 50. Therefore, even before the curing period of the bridged concrete portion 16 elapses, if the pedestal 50 is installed so as to avoid the bridged concrete portion 16 and the tank 40 is supported, the tank 40 can be quickly backfilled. For this reason, the concrete curing period for the basic concrete portion 17 is not necessary, and the construction period is shortened and the danger is very remarkable.

The pedestal 50 is provided on the foundation concrete part 17 while avoiding the bridged concrete part 16. According to this arrangement, even before the curing period of the bridged concrete part 16,
It is possible to mount the tank 40, and the construction can be completed promptly. The size, shape, installation location, and number of installations of the gantry 50 are merely examples, and, for example, if the installation method is stable without burdening the bridged concrete section 16,
It is also possible to install only one gantry 50 at an appropriate place.
