Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention is for constructing a water tank which has a high degree of construction freedom and can be constructed by effectively utilizing the site according to the shape of the site and which is also excellent in strength stability. Related to the water tank components of
It also relates to a water tank using it.

2. Description of the Related Art An example of a conventional water tank construction method that is considered to be applicable to the construction of a water tank for storing sewage such as rainwater, sewage, and factory wastewater is, for example,
No. 34306 and Japanese Patent Publication No. 63-350
What is disclosed in Japanese Patent No. 92 is proposed.

The former construction method is as shown in FIG.
A plurality of box-shaped blocks c having an opening b on a desired side surface a are arranged in parallel in the front-rear direction and in a plurality of rows on the basic concrete d, and the block juxtaposed body forms a first water storage portion e. At the same time, the second water storage part h is formed by installing the cover plate g on the pedestals f, f provided between the upper parts of the blocks in each row, and the first water storage part e, h I was building a water tank. The latter water tank is shown in Figure 15.
As shown in FIG. 5, blocks T each having a substantially inverted T shape are arranged in parallel in the front-rear direction and in a plurality of rows on the foundation concrete d, and an opening j is formed on a required side surface in each row of blocks, and the blocks of each row are formed. A bottom plate k is provided between the bottom parts of the blocks, and a cover plate m is installed between the top parts of the blocks in each row, and a water tank is constructed by a collection of water storage parts n formed by these.

[0004]

However, there are the following problems when the above-mentioned construction methods are used. The upper space of the water storage tank constructed by each of the construction methods is used according to the purpose, such as a parking lot or a park, but in proportion to the vertical load generated according to the usage situation, earth pressure and The seismic force is applied in a direction orthogonal to the length direction of the water storage portion as indicated by the arrow in FIG. 16, and a bending moment or the like acts on the water storage portion. By the way, in the water storage tank constructed by using the box-shaped block or the inverted T-shaped block, the water storage parts e, h, and n are appropriate in that the cross-section in the lengthwise direction corresponds to the proof stress. Since it is not built in the span and is rather long, the bending moment and the like acting on it are considerable. However, the water reservoir constructed in this way is not structured such that the partition wall that traverses the water reservoir is systematically arranged by the precast member. Therefore, the water tank may become unstable in strength as it is. Therefore, it is necessary to properly arrange a partition wall that crosses the water storage section in each water storage section according to the usage of the upper space of the water storage tank. The partition wall had to be formed by the construction, and many post-construction works such as reinforcement work and formwork construction were required. Thus, the conventional construction method has been a major obstacle in terms of structural stability, construction period, and construction economy.

Further, when the construction method is used, the lateral width o of each water storage portion is the same over the entire length in the lengthwise direction of the water storage portion, and the front-rear length of each block has to be constant. When constructing a water tank on a site q having an inclined side p as shown in 16, a part r on one end side thereof
However, there was no choice but to have a step shape having a vertical step s equal to the length of the block in the front-rear direction and a horizontal step t having a width that is an integral multiple of the block horizontal width. For this reason, the conventional construction method has a drawback that it is difficult to construct the water tank by effectively utilizing the site because the construction flexibility that can cope with the terrain is small. If the water tank can be constructed by changing the lengthwise width and width of the water reservoir as shown by the one-dot chain line in FIG. 16 (indicated by the symbol u), the dead space should be minimized as much as possible to effectively utilize the site. However, it was not possible to meet such a request.

The present invention provides a water tank constituent member and a water tank using the same, which can solve the above-mentioned problems of strength and flexibility of construction of the water tank, as well as problems of construction economy. It is intended.

[0007]

In order to solve the above problems, the present invention employs the following means. That is, the water tank constituent member according to the present invention includes a corner strut in which two mutually perpendicular surfaces of the strut body are joint surface portions, and front and rear elevations of the strut body are joint surface portions, and either of the left and right elevation surfaces thereof. A first intermediate column provided with a joint surface portion on one side, a second intermediate column provided with front, rear, left, and right elevations of the column body as the joint surface portion, and arranged so as to cover between the facing joint surface portions and at both ends. And a wall plate provided with a joint surface portion.

The water tank constituent member may further include a third intermediate strut in which only the front and rear elevations of the strut body are joint surface portions.

In each of the above-mentioned water tank constituent members, each joint surface portion is provided with a vertically continuous recessed groove that is open above and extends to the vicinity of the lower end of the joint surface portion. It is preferable to form them alternately in the directions.

In the water tank according to the present invention, corner struts are erected at respective corners of the water tank to be constructed, and an intermediate portion is provided at a required portion of a space surrounded by the corner struts or a required portion between the corner struts. The columns (first intermediate column and second intermediate column) are erected, and the arrangement state of these columns is set so as to be located at the intersection point of the lattice, and also covers each of the facing joint surface portions. The wall plates are arranged as described above, and the joint surface portions of the wall plates and the joint surface portions of the columns are connected to each other to form an aggregate of rectangular cylindrical compartments, and the bottom of each compartment is appropriately formed. It is characterized in that it is laid out and concrete is placed at the bottom, and that each partition has a required partition wall located inside the water tank with an opening for allowing water to flow in and out. is there.

In the water storage tank, a third intermediate support column according to claim 2 is erected between the intermediate support columns or between the corner support column and the intermediate support column, and a wall plate is provided so as to cover each of the facing joint surface portions. It may be arranged and may connect the joint surface part of a wall board and the joint surface part of a support pillar mutually.

Further, in the above-mentioned water storage tank, as the water storage tank constituent member, one in which a joint surface portion is provided with a vertically continuous recessed groove which opens upward and extends to the vicinity of the lower end thereof is used. It is preferable that the formed vertical cavity is filled with grout.

In each of the water storage tanks, it is preferable to set the aspect ratio of the compartments to 1: 3 or less in plan view.

[0014]

According to the present invention, however, the arrangement of the columns can be set as desired, and the columns can be covered with a wall plate having a required width. Therefore, the lengths of the vertical and horizontal sides of the rectangular tubular compartment can be reduced. It can be set freely. Therefore, the water tank can be constructed in accordance with the dead space that has conventionally been forced to become a dead space. Moreover, since the inside of the water tank is appropriately partitioned by a partition wall, the entire water tank can be strengthened,
It will be possible to construct a water tank with a stable structure that can resist earth pressure and seismic force.

In particular, when a water tank constituent member is provided in which the joint surface portion is provided with upper and lower concave grooves which are open upward and near the lower end thereof, the vertical direction formed by matching the concave grooves of the joint surface portion. By filling the long cavity with grout, the protrusion and the recess provided on the bottom surface of the groove can be integrated with the hardened material of the grout, and the shear resistance of the joint can be increased.
