[0025] Hereinafter, a water stop plate for a boundary stone according to an aspect of the present invention will be described with reference to the drawings.

[0026] FIG. 1 is a perspective view showing a state where a water stop plate for a boundary stone and a basic water stop plate according to an aspect of the present invention are installed at the entrance of an underground parking lot. FIG. 2a is a perspective view of the basic water stop plate of the present invention. FIGS. 2b and 2c are a gap closing plate provided at the front end of the basic water stop plate of the present invention and an enlarged view thereof. FIG. 3 is a perspective view showing a state where the basic water stop plates of the present invention are connected and installed to each other. FIG. 4 is a perspective view of the water stop plate for a boundary stone of the present invention. FIG. 5 is a plan view of the water stop plate for a boundary stone of the present invention. FIG. 6 is a perspective view showing a state where a boundary closing plate of the water stop plate for a boundary stone of the present invention is coupled to a boundary wall panel. FIG. 7 is a perspective view and an enlarged cross-sectional view showing a state where a lower closing plate coupled to the lower end of the boundary closing plate of the present invention is installed.

[0027] The water stop plate 20 for boundary stones according to one aspect of the present invention is connected and installed on the left or right side end of a water stop wall formed by continuously connecting a basic water stop plate 10 including a bottom plate 12 fixed to a floor surface 40 and a wall surface plate 14 extending upward at the rear end of the bottom plate 12. It is fixed to the floor surface 40 and includes a boundary bottom plate 22 connected and installed on the bottom plate 12 of the basic water stop plate 10, a boundary wall surface plate 24 extending upward at the rear end of the boundary bottom plate 22 and connected and installed on the wall surface plate 14 of the basic water stop plate 10, and a boundary closing plate 26 fixed to a boundary floor surface 50 formed higher than the floor surface 40 with a step on the side end of the floor surface 40 while being coupled to the boundary wall surface plate 24. The boundary floor surface 50 formed with a step higher upward on the side end of the floor surface 40 can perfectly block the outflow of water.

[0028] The basic water stop plate 10 includes a bottom plate 12 and a wall surface plate 14, and can be continuously connected left and right to form a water stop wall.

[0029] The water stop wall can block the outflow of water to the rear side. The water stop wall is installed at the entrance of an underground parking lot, an underground road, an underground shopping street, an underground building, etc., and can be used for flood prevention by blocking the outflow of water to the underground space on the rear side.

[0030] The bottom plate 12 of the basic water stop plate 10 is installed on the floor surface 40 such as the entrance to the underground space, and can be formed in a plate shape such as a square, a rectangle, or a trapezoid. The trapezoidal shape can be used when installing the water stop wall in an arc shape bulging forward or backward.

[0031] The wall surface plate 14 extends upward from the bottom plate 12, and may extend vertically upward or may extend slightly inclined toward the front side. The vertically upward or front-inclined shape can prevent the basic water stop plate 10 from falling backward. The wall surface plate 14 can be formed in a plate shape such as a square or a rectangle.

[0032] The connecting part between the wall panel 14 and the bottom plate 12 can be bent into a right-angled shape or a gentle curved surface shape.

[0033] The basic water stop plate 10 can be connected and installed by overlapping each other, connecting each other with a ring, string, etc., or inserting and connecting each other.

[0034] Referring to FIGS. 2 and 3, an insertion port is formed on one side of the basic water stop plate 10, and an insertion protrusion is formed on the other side, and the insertion protrusion can be inserted into the insertion port and coupled. For example, a lower insertion port 122 is formed at the front end of one side of the bottom plate 12, and an upper insertion port 142 is formed at the upper end of one side of the wall panel 14. A lower insertion protrusion 123 is formed at the front end of the other side of the bottom plate 12, and an upper insertion protrusion 143 is formed at the upper end of the other side of the wall panel 14. The insertion protrusion can be inserted into the insertion port and coupled. The lower insertion port 122 and the upper insertion port 142 can be formed wide in the left-right direction. The wide lower insertion port 122 and upper insertion port 142 can easily adjust the width of the water stop wall body by adjusting the overlapping degree of the basic water stop plates 10.

[0035] Including a pair of floor surface protrusions 124 that protrude upward from the bottom plate 12 and gradually increase in height toward the rear, and a pair of wall surface protrusions 144 that protrude in the front direction of the wall panel 14 and are arranged side by side, and the wall surface protrusion 144 can be connected to the floor surface protrusion 124.

[0036] The floor surface protrusion 124 can gradually increase in height, width, etc. toward the rear starting from a position spaced a certain distance toward the rear side at the front end of the bottom plate 12. When the bottom plate 12 is square, the pair of floor surface protrusions 124 are formed in a side-by-side shape. When the bottom plate 12 is trapezoidal, it may be a trapezoidal shape with a wide front or a wide rear.

[0037] The pair of wall surface protrusions 144 are preferably formed in a side-by-side shape and the lower part thereof is connected to the floor surface protrusion 124. The pair of wall surface protrusions 144 may be bent and extended at a right angle from the pair of floor surface protrusions 124, or may extend in a gently curved surface shape.

[0038] In the wall panel 14, an upper protrusion 145 that protrudes in the front direction and connects the upper ends of the pair of wall surface protrusions 144 left and right, and a handle hole 146 formed through below the upper protrusion 145 may be further included.

[0039] The handle hole 146 is very convenient when moving and installing the basic water stop plate 10, etc. After using the basic water stop plate 10, it can be stored by tying it with a string, wire, etc. through the handle hole 146 in a stacked state. Also, a plurality of basic water stop plates 10 can be easily moved using the tied string or wire.

[0040] In the wall panel 14, a lower protrusion 147 that protrudes in the front direction and connects the lower parts of the pair of wall surface protrusions 144 left and right may be further included.

[0041] An auxiliary floor surface protrusion 125 protruding upward may be further included between the pair of floor surface protrusions 124. The auxiliary floor surface protrusion 125 can gradually increase in height, width, etc. as it goes toward the rear starting from a position separated by a certain distance at the front end of the bottom plate 12. One or more auxiliary floor surface protrusions 125 can be formed.

[0042] Also, an auxiliary wall surface protrusion 148 that connects the wall surface protrusions 144 on both sides may be further included between the upper protrusion 145 and the lower protrusion 147. The auxiliary wall surface protrusion 148 can be formed with a smaller protruding height than the upper protrusion 145 and the lower protrusion 147.

[0043] Also, reinforcing protrusions 149 protruding in a dumbbell shape may be further included on both sides of the pair of wall surface protrusions 144.

[0044] The basic water stop plate 10 may further include an adhesion member attached in a strip shape such as rubber, silicone, plastic, non-woven fabric, or woven fabric at a portion overlapping with an adjacent basic water stop plate 10, a portion overlapping with the water stop plate 20 for boundary stones, or a portion in contact with the floor surface 40. The adhesion member can remove the gap between the basic water stop plates 10, between the basic water stop plate 10 and the water stop plate 20 for boundary stones, and between the basic water stop plate 10 and the floor surface 40 to block water leakage, prevent slipping, and enable firm connection between them.

[0045] The floor surface protrusion 124, the wall surface protrusion 144, the upper protrusion 145, the lower protrusion 147, the auxiliary floor surface protrusion 125, etc. can greatly increase the rigidity of the basic water stop plate 10 so that it can withstand water pressure well even with less material.

[0046] It may further include a gap blocking plate 127 coupled to the front end of the bottom plate 12. The gap blocking plate 127 can block the gap generated between the front end portion of the bottom plate 12 and the floor surface 40 when the floor surface 40 is inclined. That is, when the floor surface 40 is inclined in a curved surface shape, the front end portion of the bottom plate 12 is lifted. In this case, the gap blocking plate 127 can prevent water from flowing downward by blocking the gap. The gap blocking plate 127 can be rotatably coupled to the front end of the bottom plate 12 or coupled to incline downward to better block the gap. Also, the gap blocking plate 127 may be detachably coupled to the front end of the bottom plate 12 or installed in a completely coupled structure.

[0047] Referring to FIGS. 4 to 7, an angle height adjustment portion 30 for connecting the boundary closing plate 26 and the boundary wall surface plate 24 can be further included. The angle height adjustment portion 30 can include an arc-shaped concave groove 32 formed at an end of the boundary wall surface plate 24 and a rectangular convex portion 34 formed at an end of the boundary closing plate 26. The rectangular convex portion 34 can be slidably inserted into the arc-shaped concave groove 32 from above to below. Depending on the degree of insertion of the boundary closing plate 26, the vertical installation height can be adjusted, and detachment in the side direction is prevented. Since the convex portion 34 can rotate within the concave groove 32, it can well accommodate changes in the height and width of the boundary floor surface 50.

[0048] The arc-shaped concave groove 32 is formed vertically long at an end of the boundary wall surface plate 24, and the side surface and the upper side may be open. The arc-shaped concave groove 32 may be formed over the entire upper and lower portions of the end of the boundary wall surface plate 24, or may be formed only in a part of the upper portion. When formed only in a part of the upper portion, it is desirable to form it up to the minimum height of the boundary floor surface 50.

[0049] The rectangular convex portion 34 can be formed over the entire upper and lower portions at the side end of the boundary closing plate 26. By slidably inserting the rectangular convex portion 34 into the arc-shaped concave groove 32 from above to below, it can be installed by lowering it to the boundary floor surface 50. Further, the convex portion 34 can be appropriately rotated within the concave groove and installed according to the width of the boundary floor surface 50, so that no outflow space is generated on the side surface.

[0050] A boundary side surface plate 28 for connecting the boundary bottom plate 22 and the end of the boundary wall surface plate 24 can be further included. The front upper side of the boundary side surface plate 28 is cut off, and the water flowing into the outside and the inside of the boundary side surface plate 28 can flow left and right easily, and the water pressure difference can be quickly removed. The boundary side surface plate 28 can connect the boundary bottom plate 22 and the boundary wall surface plate 24 to increase the structural rigidity of the water stop plate 20 for boundary stones.

[0051] A part of the central portion of the arcuate concave groove 32 can be opened between the boundary side plate 28 and the boundary wall plate 24. By opening between the boundary side plate 28 and the boundary wall plate 24, it becomes easier to manufacture the mold and the manufacturing cost can be reduced.

[0052] The boundary closing plate 26 may be formed in an arc shape and flanges may be provided at the upper and lower ends. The arc shape and the flanges at the upper and lower ends can well cope with a large water pressure in order to increase the rigidity of the boundary closing plate 26.

[0053] Referring to FIG. 7, a lower closing plate 29 coupled to the lower end of the boundary closing plate 26 can be further included. The lower closing plate 29 can be installed so as to incline forward and downward. The lower closing plate 29 can be formed of a flexible material. The lower closing plate 29 made of a flexible material can perfectly block the outflow of water even when the boundary floor surface 50 is inclined forward and backward or left and right. The flexible material can include rubber, silicone, flexible plastic, etc. Also, the boundary closing plate 26 may be made of a non-flexible iron material, plastic, etc.

[0054] The lower closing plate 29 can be integrally coupled to the lower end of the boundary closing plate 26 with an adhesive, or can be detachably coupled by fitting. In the case of fitting, it can be fitted and coupled by an arcuate concave portion formed on either one of the lower end of the boundary closing plate 26 and the upper end of the lower closing plate 29 and a rectangular convex portion formed on the other side. When the lower closing plate 29 is not needed, the fitting can be removed and stored.

[0055] The water stop plate 20 for the boundary stone and the basic water stop plate 10 can be installed by overlapping each other, coupled to each other with a ring, a string, etc., or inserted and coupled to each other.

[0056] The insertion connection can be similarly applied to the insertion connection of the basic water stop plate 10 in FIGS. 2 and 3. That is, an insertion port is formed in either the basic water stop plate 10 or the water stop plate 20 for boundary stones, and an insertion protrusion is formed in the other, and the insertion protrusion can be inserted into the insertion port and coupled. That is, the insertion connection between the water stop plate 20 for boundary stones and the basic water stop plate 10 can be performed in the same manner as the insertion connection between the basic water stop plates 10 described above.

[0057] The water stop plate 20 for boundary stones can further include an adhesion member attached in a strip shape such as rubber, silicone, plastic, non-woven fabric, or woven fabric at a portion overlapping with an adjacent basic water stop plate 10 or a portion in contact with the floor surface 40. The adhesion member can remove the gap between the water stop plate 20 for boundary stones and the basic water stop plate 10, and between the water stop plate 20 for boundary stones and the floor surface 40, block water leakage, prevent slipping, and enable good connection with each other.

[0058] The method of simply overlapping and installing the water stop plate 20 for boundary stones and the basic water stop plate 10 can well correspond to the size of the installation width of the water stop plate 20 for boundary stones formed at the end of the water stop wall body.

[0059] As described above, all the components constituting the embodiments of the present invention have been described as being combined or operating in combination. However, the present invention is not necessarily limited to these embodiments. That is, within the scope of the present invention, all the components may be selectively combined in one or more to form or operate.
