BEST MODE FOR CARRYING OUT THE INVENTION
Due to such a configuration, the water stop plate for flood prevention according to the present invention can be used to prevent the water stop frame plate from being disassembled and stored in advance in the event of sudden flooding due to urban flooding, for example, torrential rain. For example, it is transported and assembled in a submerged area such as a subway or an underground shopping street entrance, surrounded by the inundation port and waterproofed, and the flow is deflected to prevent the underground lowland from flowing. Of course, these waterstops can be used effectively to prevent flooding in urban rivers. The preferred embodiments of the present invention will be described below with reference to the drawings.
[0007]
【Example】
As shown in FIGS. 1 and 3, the flood-preventing water stop plate of the present invention mainly includes a water stop frame plate (2) in which an appropriate number of steel frame bodies shown in FIG. One waterproof cloth (4), a pair of front and back fall-preventing metal fittings (3) assembled on the waterproof frame plate (2) from the cloth, and a second waterproof cloth covering these structures. It consists of a combination with (5).
[0008]
Such a water stop frame plate (2) of the flood prevention water stop plate (1) is preferably a steel water stop frame plate as shown in FIG. 2 , depending on the amount of flood water. As shown in Fig. 3, it is advantageous to construct one or two sheets (2) (2) or one stage (2 ') or two stages (2') (2 ') by appropriately adjusting their dimensions. is there.
[0009]
The water-stop frame plate (2) constructed according to the amount of water is covered with a slightly thinner first waterproof cloth, for example, a vinyl synthetic resin cloth (4), and the water-stop frame plate ( 2) The sandbag (6) (6) (6) (6) (6) (6) (2) is completely covered to prevent leakage of water from the seam, connection hole, etc. 6). . Are arranged.
[0010]
On the water-stop frame plate (2) coated to prevent leakage as described above, a plurality of pairs of anti-tip fittings (3) and (8) shown in FIGS. 4 and 5 are adjacent to each other. However, the tip of the first waterproof cloth (4) sandwiched between them is attached to the tip of the metal fitting, while being sandwiched in the opposite direction and fixed so that the waterstop frame plate is fixed and supported so as not to fall down. Reinforcing bar pile driving part (7), pile (B) (B) driven into this. . And the sandbags (6) (6) provided under the feet of the water-stop frame plate (2) are firmly fixed to the ground and pressed against being swept by the water flowing from the side. Yes.
[0011]
Furthermore, the front and back integrated fall-preventing metal fittings (3) and (8) were formed by bending the water-stop frame plate (2) covered with the first waterproof cloth as described above into an inverted U-shape. At the same time as being sandwiched in the space (2 ′) between the sandwiching portions (10) and (11), an L-shaped horizontal extension stabilizing portion (12) bent further at a right angle from the sandwiching portion and a pile driving connected thereto It is configured to prevent the water-stop frame plate from overturning by means of the part (7) and to reinforce the strength of the entire metal fitting by means of the crossing part (9) attached to cross this L-shaped part. Has been.
[0012]
As shown in FIGS. 4 and 6, the pair of fall-preventing metal fittings (3) and (8) are opposite to each other, that is, the pile driving portion (7) of the metal fitting (3) 8) The water stop frame plate (2) is sandwiched from both the front and back surfaces by the inverted U-shaped portions (10) and (11) so that the same portion (7) is located behind the back surface, and each L-shaped portion. (11) It is constructed such that the horizontal extension stabilizing part (12) of (12) and the pile driving part (7) (7) support the water stop frame plate (2) with certainty.
At this time, the crossing portion (9) of the L-shaped portions (11) and (12) of the fall-preventing metal fitting, together with the pile driving portion (7), is subjected to flood water pressure from the direction of the arrow (P) described later. In order to sufficiently antagonize and sufficiently prevent the water-stop frame plate (2) from overturning and destroying the metal fittings, the front and back are reinforced integrally.
[0013]
In this way, the flood (W) can be prevented from overflowing, but for the purpose of complete waterproofing, a slightly thicker second waterproof cloth (5) is assembled, and the fall-preventing bracket is assembled. (3) (8) Water-stop frame plate (2) covered with the first waterproof cloth (4) using the water pressure (P) of the flood (W) applied from above and applied from the vertical and horizontal directions In addition, this cloth is brought into close contact with the metal fittings (3) and (8) for preventing the fall, and in addition to preventing further leakage of water, the first waterproof cloth and the waterstop frame plate due to driftwood and the like are prevented from being damaged. To be useful.
If necessary, it is also possible to construct a sandbag with an appropriate capacity in parallel with the flood-side tip of the second waterproof cloth (5) so as to prevent flaking at the tip due to flow.
[0014]
On the other hand, as shown in FIG. 6, the flood-preventing water stop plate (1) comprising the steel frame of the present invention shown in FIG. 2 has a predetermined-size thinned lumber (2T) combined by a stacked mandrel (13). ) Can be used instead.
This frame board is advantageous because it is very effective and can be supplied at a relatively low cost since thinning materials of various kinds of wood that are currently being used are used.
[0015]
On the other hand, the first and second waterproof cloths (4) and (5) are preferably cloths made mainly of synthetic resin. However, they are waterproof and can withstand the water pressure of floods, driftwood, various drifting objects, etc. Therefore, it is preferable that the cloth body is a material that is relatively light and easy to sew, and that can be connected with a waterproof chuck or the like.
[0016]
Further, the fall prevention metal fittings (3) and (8) are made of a rigid body having an appropriate strength, such as metal, plastic, wood, etc., but have a rigidity capable of withstanding the strong pressure of flooding, and are lightweight and compared. For example, when it is a metal, a coated steel plate, a stainless steel plate and the like which are not easily oxidized by water and can be easily obtained are preferable.
[0017]
Due to such a construction, the flood-preventing water stop plate (1) of the present invention has the first and second waterproof cloths (4) depending on the vertical and horizontal water pressures of the flood (W), as shown in FIGS. ) (5) is a dangerous place where the former is in direct contact with the water-stopping frame plate (2) to prevent flood inflow and leakage and change the direction of water flow to the desired direction. It is relatively easy to prevent inundation and flooding of important locations such as houses, lowlands, and underground shopping areas with a small number of people and small effort.
