Description

The present invention belongs to a technique for reinforcing horizontal resistance applied to a storage space for constructing a storage tank of a rainwater outflow suppression facility.

A method of constructing a rainwater outflow control facility that temporarily stores rainwater and gradually discharges it by placing resin blocks in the basement is widely used. Since it is made of resin, if it is built underground, it is necessary to consider deformation due to creep due to earth pressure and water pressure, and reduction in strength. Since there is a need to save resources, means for arranging blocks in a space has been proposed. For example, there is JP 2008-255767.

In the method of providing a gap between blocks arranged from the viewpoint of resource saving, the present invention relates to a method for enhancing resistance in a horizontal direction of a block made of a resin board and legs that open to the board.

The present invention combines a flat plate portion and a block made of legs that open to the flat plate portion into a unit in a state where the bottom portion of the leg portion is opposed to each other. In the storage space embedded in the basement covering the periphery and the ceiling of the structure formed by the pillars, the flat parts facing the blocks adjacent to each other in the arranged pillars A plate member having a positioning portion is inserted between the flat plate portions that are connected to each other by a joint and the blocks constituting each column body, and the horizontal force applied between the inserted plate members is linearly applied to the storage space. This is a storage space for constructing a storage tank of a rainwater outflow control facility constructed so as to be transmitted from end to end.

The present invention combines a flat plate portion and a block made of legs that open to the flat plate portion into a unit in a state where the bottom portion of the leg portion is opposed to each other. In the storage space embedded in the basement covering the periphery and the ceiling of the structure formed by the pillars, the flat parts facing the blocks adjacent to each other in the arranged pillars A plate member having a positioning portion is inserted between the flat plate portions that are connected to each other by a joint and the blocks constituting each column body, and the horizontal force applied between the inserted plate members is linearly stored in the space. Since it is a storage space for constructing a storage tank of a rainwater outflow suppression facility constructed so as to be transmitted from end to end, there are the following effects.
1. By connecting the flat plate portions of the column bodies adjacent to each other at intervals, a force applied in the horizontal direction is transmitted linearly from end to end of the storage space.
2. Since the plate material is inserted between the flat plate portions of the column bodies adjacent to each other at an interval so that the horizontal force applied to the plate material is linearly transmitted from end to end of the storage space, the allowable stress applied in the horizontal direction is increased. . .

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1a shows examples of blocks, joints, and plates used in the present invention.
In FIG. 1a, the block is composed of a board body and a cylindrical leg portion that opens to the board body, and female holes for joints are provided at the four corners of the board body surface on a surface slightly lowered from the board body surface. In the drawing, the leg has a square cross section and is tapered so as to open to the board and become narrower toward the bottom. The cross section of the leg can be arbitrarily selected, such as a circle, a polygon, and a plum bowl shape protruding outward, and the number of legs can also be selected.
In the drawing, the joint is a square flat plate, and the four corners are convex male joints corresponding to female holes provided on the surface of the block board. A portion where the joint exists is lowered one step, and the connection surface of the joint is configured to be flat.
As shown in FIG. 2, a joint capable of connecting four blocks is shown. .
The plate has a cross shape in the figure, and a convex part corresponding to the shape of the leg is provided as a positioning part in the center, and the board is inserted into the leg that opens to the board surface, so that the position and direction relative to the board surface Can be matched. The positioning part is not limited to this example, and the position may be adjusted by providing a connecting part on the surface of the block board body and connecting the part extending in a cross shape. In particular, when the leg section has a circular shape and only one leg in the center, the position is determined because it rotates, but the direction is not determined. Therefore, it is preferable to employ an engagement part.

In the block shown in FIG. 1b, a plate material is inserted through a groove provided on the surface of the block body of the block so that no gap is generated between the plate bodies into which the plate material is inserted. Since this member is not fundamentally different from the member shown in FIG. 1a, the following description is based on the member shown in FIG. 1a.

FIG. 2 shows a state in which the board parts are connected by the joints and the plate material is inserted between the board bodies. 2a shows a joint, FIG. 2b shows a state in which both a plate material and FIG. 2c are used.
In FIG. 2a, the state which connects four column bodies is shown by connecting the board which comprises a column body with one coupling. In the drawing, four board bodies are connected by one joint, but two board bodies may be connected by using a joint having one joint at both ends. It is also possible to connect both sides of the corresponding board side of the column body facing each other in parallel, or connect the centers of the sides of the board body.

FIG. 2 b shows a state in which the plate material is sandwiched between the board bodies. In the figure, the center portion of the plate material is a square trapezoid corresponding to the shape of the leg portions on the front and back sides as positioning portions. The arm extends so as to be orthogonal to the four directions around the center, and the end surface of the arm is configured to reach the center between the adjacent columns.
It is not limited to this shape, and it is only necessary that the end faces of the arms extending in four directions coincide with each other to transmit a horizontal force.
Accordingly, the plate material is linearly connected to the left and right, and the horizontal force applied to the column is transmitted linearly from end to end by the present plate material.
FIG. 2c shows a state where both the joint and the plate are used.

FIG. 3 shows a structure in which pillars are connected by a joint and a plate material.
Since the end of the structure is in a state in which the cross portion of the plate material protrudes, if the material permits, the excess portion can be cut or the plate material of the portion that contacts the sides and corners can be processed in advance.

FIG. 4 shows a storage space that surrounds the structure obtained above and covers the ceiling with a ceiling material.
The surrounding wall material can be a metal plate or resin plate, and it can be turned around, screws, bolts / nuts, or wire. Secure to the structure using a string.
The ceiling part may also be constructed by stretching a metal plate, a resin plate or a concrete plate so as to cover the plurality of pillars.

FIG. 5 shows a storage tank for controlling the outflow of rainwater and the like, in which necessary storage facilities such as an inflow / outflow pipe, an orifice and the like are wrapped in a sheet to wrap this storage space and collect mud. If the permeation tank is used, a water permeable sheet is used. If the storage tank is used, a water shielding sheet is used as usual.

It is used as a temporary storage tank used for rainwater outflow control facilities and a temporary storage tank for contaminated water.
