Japanese Patent Laid-Open No. 2001-98792 Utility Model Registration No. 3166822 Japanese Patent No. 4898973

  The conventional waterproofing device has an advantage that a water blocking wall can be formed by inserting a water blocking plate between the columns in a short time in an emergency by standing up a column in advance along the entrance of the structure. . However, if such columns are installed at the entrances and exits of urban houses and shops, the appearance will be worse, and the width of the entrance will be reduced by the amount of columns installed, passing through the entrance. In some cases, your hands or feet may hit the pillars, which may hinder your access to the building.

  When installing a waterproof device in places where people come and go frequently, such as in urban houses and stores, as in the column 103 of the portable embankment 100 shown in FIG. It is preferable that it is configured so that it can be detachably installed, but in that case, if there is even a slight gap between the outer surface of the structure facing the road side and the pillars erected on the foundation, It is inevitable that water will enter the water blocking wall from the gap and the structure will be submerged. When the column is configured to be detachable, it is necessary to take measures to prevent water from entering the column and the outer surface of the structure without any gaps while the column is installed on the foundation. is there.

  In the present invention, in view of such problems of the prior art, in a water blocking wall structure installed facing a doorway of a structure, a column can be detachably installed on a foundation near the doorway. In addition to this, an object is to close the space between the installed support column and the outer surface of the structure in a watertight manner so that water does not enter the water blocking wall.

In order to solve the above-mentioned problem, the present invention is to insert a support column into a plurality of holes formed on the upper surface of the foundation and arrange the support column on the foundation, and in the recessed groove provided on the side of the support column, the side edge of the wall panel. In the column of the water blocking wall structure that forms a water blocking wall by attaching a wall panel between the columns, the peripheral side portion of the column excluding the side portion provided with the concave groove. In this case, the elastic material is attached to the surface portion extending from the lower end of the portion exposed on the foundation when inserted into the hole portion to at least the height of the position where the wall panel is attached.
As another form of the support, the present invention provides the support post, wherein the support post is formed by providing a recessed groove on one side portion of the circumferential side portion provided in a polygonal cross-sectional shape in plan view. The height of the position where at least the wall surface panel is attached from the lower end of the portion exposed on the foundation when the support column is inserted into the hole portion, at least one of the peripheral side portions excluding the provided side portion. It is characterized by having a configuration in which an elastic material is attached to the surface portion leading to this.

  According to this, the position of the hole provided in the foundation is set so that the elastic material attached to the peripheral side portion of the support sticks to the outer surface of the structure when the support is inserted into the hole. Therefore, if there is a risk of inundation of the structure due to heavy rain, etc., if the hole is inserted into the column, the elastic material on the peripheral side of the column upright on the foundation will adhere to the outer surface of the structure as it is. As a result, the gap between the support and the structure is closed, and water does not enter the water blocking wall from between the two members. Other members and means for closing the gap between the two members, such as mounting a cover material along the gap between the support column and the structure, are unnecessary.

Attach the elastic material to the struts on the surface of the structure at least when the struts are standing on the foundation within the peripheral side parts of the struts except the side where the concave grooves where the wall panel is mounted are installed. It must be attached to the surface portion including the side of the facing location. If elastic material is attached to the entire peripheral side of the column, excluding the side where the concave groove is provided, there is no need to consider the directionality of the column's installation position relative to the structure when installing the column. preferable.
The elastic material was held between the columns as long as it was attached to the surface part from the lower end of the portion exposed on the foundation when the column was inserted into the hole to at least the height of the position where the wall panel was installed. It is possible to reliably prevent the water at the water level stopped by the wall panel from entering the inside of the water blocking wall from between the support column and the structure. An elastic material may be attached to the whole from the lower end to the upper end of the portion exposed on the foundation of the support column.

As the material of the elastic material to be attached to the surface of the column, it has good weather resistance, easily compresses and stretches, and adheres to a flat part or curved part of the structure surface, or an inclined surface or uneven rough surface. Using materials that exhibit high water-tightness, such as rubber made of synthetic resin such as ethylene propylene diene rubber or butyl rubber, or foams that are foamed from closed cells or semi-closed cells with continuous cells. Can do.
If these materials are used, the elastic material closely adheres to the outer surface of the structure when the support is erected on the foundation, and good watertightness can be obtained. When the elastic material is formed by processing a commercially available material, the use of “Eptosealer” (registered trademark; manufactured by Nitto Denko Corporation), which is a semi-independent semi-open cell foamed product mainly composed of ethylene propylene diene rubber. Is preferred.
The elastic material can be attached to the column using a fixing means such as a double-sided adhesive tape.

  In order to improve the water tightness of the contact portion between the elastic material and the outer surface of the structure, the elastic material is preferably provided so as to be in close contact with the structure in a state in which the elastic material is appropriately crushed and compressed from the original state before contacting the structure. For example, if an elastic material with a thickness of about 30 mm is attached to the surface of the support and the support is set up on the foundation, the elastic material comes into contact with the surface of the structure and compresses to a thickness of about 10 mm to 20 mm. The compressed elastic material closely contacts the structure surface and closes the gap between the two members, so that the space between the column and the structure surface is reliably sealed by the elastic material. In this case, the position of the hole provided in the foundation needs to be set so that the elastic material is tightly bonded to the outer surface of the structure when the support is inserted into the hole.

  The strut having the above structure is a lower region of the strut that is inserted into the hole, and is formed between the inner surface of the hole and the strut surface along the surface of the strut facing the upper end of the hole with the strut being inserted into the hole. A ring-shaped elastic material for closing the gap is attached, and a stopper piece that engages with the upper surface of the foundation around the hole is provided on the outer surface of the support column above the position where the ring-shaped elastic material is attached. In addition, a hook-shaped elastic material is fitted on the outer periphery of the support column, and the hook-shaped elastic material can be provided to overlap the lower surface of the stopper piece.

According to this, a support | pillar can be stably stood on the upper surface of a foundation by inserting a support | pillar in a hole, inserting the lower area | region of a support | pillar in a hole, and a stopper piece engaging with the upper end of a hole. .
The ring-shaped elastic material fixed to the surface of the lower region of the column with the column inserted into the hole is pressed between the surface of the column and the inner surface of the hole by its own elasticity. The ring-shaped elastic material that is in close contact with the inner surface of the portion effectively closes the gap between the hole inner surface and the column surface at the upper end of the hole, and effectively prevents water from leaking through the gap. Can do.
The ring-shaped elastic material has a size that closes the gap between the inner surface of the hole and the surface of the support when the support is inserted into the hole, so that the hole does not interfere with the operation of inserting the support. About the size, that is, can be formed by setting the inner shape dimension of the hole part slightly larger than the outer dimension of the pillar, thereby ensuring the ease of the operation of inserting the pillar into the hole part, Workability at the time of installing the support can be improved.

In addition, a hook-shaped elastic material is fitted on the outer peripheral surface of the support column below the stopper piece, and this hook-shaped elastic material is placed on the lower surface of the stopper piece, so when the support column is inserted into the hole, the stopper piece As the hook engages with the upper end of the hole, the hook-shaped elastic material joins around the upper end of the hole, and at the same time, the hook-shaped elastic material is formed at the lower end of the wall panel laid between the lower surface of the stopper piece and the column. Pressed downward and compressed, tightly fitted into the gap between the surface of the column and the inner surface of the hole at the upper end of the hole, so that the gap between the column and the connection part of the hole is sealed, and the water stoppage of the connection part Will increase.
The bowl-shaped elastic material deforms and joins along the peripheral shape of the upper end of the hole due to its own elasticity, so even if the upper surface of the foundation where the hole is drilled is uneven or pebbles are sandwiched Even if the load due to water pressure is concentrated on the connection part with the hole part of the column and the position of the column is biased in the hole part, it follows the bias of the column and has a hook-like elasticity. The state in which the material is deformed and is closely fitted into the gap between the surface of the column and the inner surface of the hole is maintained, and a gap is formed at the connecting portion between the column and the hole, and no water leaks from there.

The ring-shaped elastic material is made of an appropriate material having elasticity, such as a rubber material or a synthetic resin material that can shrink in the thickness direction, and has an appropriate thickness in order to reliably close the gap between the column surface and the hole inner surface. It can be attached in a band-like manner along the circumferential direction of the surface of the column using a member formed in a width and length.
Moreover, the said hook-shaped elastic material can use the thing of the material similar to the said elastic material attached to the side part of a support | pillar. In addition, it is possible to use a non-woven fabric or a core material made of a synthetic resin sheet or non-woven fabric, and a laminated structure in which the front and back layers of the core material are made of a foamed elastic rubber material mainly composed of synthetic rubber. The saddle-shaped elastic material has an inner opening that is substantially the same shape as the cross-sectional shape of the support column, and the support column fits perfectly in this opening, and with the fit, the outer width of the support column has an appropriate width outward. It can form in the ring shape provided with the protruding collar part, and the width | variety of a collar part can be provided in 5 mm-about 20 mm. The thickness of the hook-shaped elastic material can be set to an appropriate dimension of about 2 mm to 10 mm, for example, depending on the compression and expansion / contraction performance of the forming material. In the case where the bowl-shaped elastic material is formed of a foamed elastic material mainly composed of ethylene propylene diene rubber or butyl rubber, the thickness can be set to about 5 mm.

Moreover, the support | pillar of the said structure can be set as the structure which provided the press means which press-contacts to the panel surface of the wall surface panel fitted in the ditch | groove of a support | pillar.
When the water stop wall is configured by mounting and supporting the wall panel on the support column, it is desirable to make the clearance between the recessed groove of the support column and the side edge of the wall panel as small as possible in order to ensure the water stop performance. On the other hand, if there is no clearance at all, it will be difficult to insert / remove the wall panel into / from the recessed groove, resulting in poor workability during assembly and disassembly.
As described above, if the column is provided with means for pressing the panel surface against the panel surface of the wall panel, when the wall panel is fitted into the recessed groove of the column, the panel surface is pushed by the pressing means. Since the side end of the groove is in close contact with the inner surface of the groove and is held at a predetermined mounting position in the groove, even if the water level is low, water stoppage performance can be maintained and water leakage can be prevented. Moreover, the clearance between the concave groove and the side edge of the wall panel can be set to a size that does not hinder the operation of inserting and removing the wall panel.
For example, the pressing means may have a configuration in which an elastic member having an appropriate shape is provided on both sides of the concave groove of the support so that a part of the elastic member slightly protrudes into the concave groove. Cylindrical or frustoconical rubber material is arranged so that a part of its peripheral surface protrudes into the groove, and is placed on one side of the groove or opposed to the outer surfaces of the columns on both sides But you can.
Further, the pressing means may be provided so as to be able to rotate while being pressed against the panel surface along the direction in which the wall panel is inserted into and removed from the support column. When the pressing means rotates while being pressed against the panel, the wall panel can be easily inserted and removed, and the wall panel can be guided and attached to a predetermined mounting position in the concave groove.
Further, a plurality of pressing means may be installed along the concave groove of the support column, for example, at three locations, the lower portion, the middle portion, and the upper portion of the support column. In this case, it is preferable to install at least one pressing means on the lower side near the lower end of the support column. By doing in this way, even if the water level blocked by the water blocking wall is relatively low and the water pressure applied to the wall panel is small, the wall panel is pressed by the pressing means installed on the lower side of the column. Thus, the joint portion between the side end portion of the wall panel and the inner surface of the concave groove of the support column is hermetically sealed to ensure water tightness, and leakage of the dammed water can be reliably prevented.

It is preferable that the support column having the above-described configuration is formed using a steel frame material having a substantially U-shaped cross section so that it can be easily carried with light weight while having necessary rigidity. A plurality of steel frame members having a substantially U-shaped cross section may be combined and fixed integrally by welding.
The lower part of the column that is inserted into the hole is provided with a partition member inside or combined to prevent the water that has entered the hole from leaking through the gap inside the column with the column inserted into the hole. It is preferable to fill with a resin material. As the synthetic resin material to be filled, for example, a lightweight synthetic resin filler such as foamed polyethylene can be used. Moreover, if a support | pillar is provided with the rigidity which supports a wall surface panel stably, it can form using materials other than steel materials, such as synthetic resin materials, such as a reinforced plastic, and concrete.

Further, the water blocking wall structure of the present invention is a strut having the above-described structure, and a plurality of struts detachably provided in holes formed on the upper surface of the foundation, and the struts arranged on the foundation. It has the structure which comprised the wall surface panel supported.
The water blocking wall structure having such a structure is based on the part facing the entrance of the structure, etc. The pillars are inserted in a plurality of holes formed in the upper surface of the foundation, and the pillars are arranged on the foundation side. A water stop wall can be formed on the foundation facing the doorway by fitting the side wall of the wall panel into the recessed groove provided in the section and attaching the wall panel between the columns.
In addition, the water stop structure of the structure entrance and exit of the present invention is installed by inserting the struts of the above-described structure into the holes formed on the foundations on both sides of the entrance and exit of the structure, and is attached to the sides of both struts. The elastic material is brought into close contact with the surface of the structure, and the water stop wall is formed along the entrance / exit by fitting the wall panel by fitting the side edge of the wall panel into the recessed groove provided on the side of both columns. It is characterized by forming.

Preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a water blocking wall structure according to an embodiment of the present invention.
As shown in the figure, the water blocking wall structure 1 has a hole 4 on the flat foundation 3 on which concrete pavement or asphalt pavement facing the structure 2 is formed and in the vicinity of both sides of the entrance / exit of the structure 2. , 4 are formed, and a pair of support columns 5 and 5 each having a recessed groove 5a on the side are inserted into the hole portions 4 and 4 so that the recessed grooves 5a face each other. 5 is inserted into the concave groove 5a of the wall 5 and the wall panel 6 is attached between the columns 5 and 5, so that an emergency water stop wall is formed on the foundation 3 facing the entrance of the structure 2. It is a structure of forming.

As shown in FIG. 2, the hole 4 includes a bottomed box-shaped steel mold 41 having an opening 41 a large enough to fit the lower part of the column 5 at the upper part, and an upper surface of the foundation 3. It is embedded in the foundation 3 so as to be flush with the end face of the opening 41a. When there is no rain, the hole 4 is in a state in which the opening 41a is closed by attaching the cover plate 42 shown in FIG. ing.
Further, as shown in FIG. 3, the wall panel 6 is made of a highly rigid and lightweight steel material, synthetic resin material, or the like, so that the lateral width spanned between the columns 5 and 5 and the side end portion thereof are recessed grooves of the column 5. It is a plate material formed to have a thickness that fits into 5a, and is formed by integrally fixing a waterproof rubber 61 made of synthetic resin having elasticity along the left and right edges and the lower side of the front surface.

  FIG. 4 shows the appearance of the column 5 of this embodiment shown in FIG. 1, and FIG. 5 shows the side and front of the column 5, respectively, and this column 5 is a wall panel on one side of its peripheral side. 6 is provided with a recessed groove 5a to which the side end portion is fitted, and a lower region thereof is inserted into a hole 4 provided by embedding a mold 41 on the foundation 3, and is formed so as to stand upright on the foundation 3. Has been.

  Specifically, the support column 5 is formed by combining a plurality of steel frame members 51 having a substantially U-shaped cross section, and the lower part thereof is integrated by welding by joining the back sides of the frame members 51 and 51, The same shape of the frame material 51 having an appropriate length is placed on the upper ends of the integrated frame members 51 and 51, and the lower end of the frame member 51 is welded to the upper ends of the lower frame members 51 and 51. It is formed integrally. The lower part of the column 5 in which the pair of frame members 51, 51 are integrated by welding is a portion that immerses into the hole 4 when the column 5 is erected on the foundation 3, and an upper part of the column 5 that is the frame member 51 thereon. Is a portion exposed on the foundation 3, and an open portion along the vertical direction on one side of the upper frame member 51 is a concave groove 5 a into which the wall surface panel 6 fits.

  The surface portion of the peripheral side portion of the frame member 51 on the upper side of the support column 5 exposed on the foundation 3 is compressed between the upper and lower end portions of the frame member 51 except for the side portion where the concave groove 5a is disposed. In addition, an elastic material 7 made of a foamed elastic rubber material having good stretchability and having a thickness of about 30 mm is integrally attached.

Further, on the lower side of the side portion of the upper frame member 51 where the concave groove 5a is disposed, as shown in FIG. 7, the truncated cone shaped rubber plugs 8 and 8 are opposed to both sides of the concave groove 5a. They are arranged and fixed to the outer surface of the side portion with a fastening screw at a position where a part of their peripheral surfaces protrudes into the groove 5a. The rubber plugs 8 and 8 are attached by inserting a retaining screw into a recessed portion at the center thereof, and are fixed to the frame member 51 so as to be rotatable around the retaining screw.
As shown in FIG. 8, the width D8 between the peripheral edges of the rubber plugs 8 and 8 attached with the peripheral surface protruding into the concave groove 5a is set to be substantially the same as or larger than the thickness D6 of the wall panel 6. Thus, the side end portion of the wall surface panel 6 can be smoothly fitted into the groove 5a. Further, the width D81 between the peripheral edge of the rubber plug 8 on one side and the inner surface of the groove 5a is set smaller than the thickness D61 including the waterproof rubber 61 on the side edge of the wall surface panel 6, and FIG. ), When the side end portion of the wall surface panel 6 is fitted into the concave groove 5a of the support column 5, the rubber plug 8 is pressed against the panel surface on the back surface side of the wall surface panel 6 to press the wall surface panel 6 outward. Thus, the water stop rubber 61 is pressed against and closely contacts the inner surface of the groove 5a, the wall panel 6 is held at a predetermined mounting position in the groove 5a, and the wall panel 6 in the groove 5a is held in place. The water tightness of the side end is ensured.

  Further, as shown in FIGS. 5 and 6, the support column 5 is filled with a filler 9 made of foamed polyethylene in the lower frame members 51, 51, which is a region to be immersed in the hole 4. The internal gap is closed, and the stopper pieces 10 and 10 made of L-shaped angle members are fixed to the left and right side surfaces of both frame members 51 and 51, and are fixed along the lower side of the stopper piece 10. A ring-shaped elastic material 11 made of a belt-like elastic rubber having an appropriate width and thickness is integrally fixed to the entire outer surface of the support column 5, and a hook-like elasticity forming a rectangular ring shape on the outer periphery of the support column 5. The material 12 is fitted, and the hook-shaped elastic material 12 is formed so as to overlap the lower surfaces of the stopper pieces 10 and 10.

As shown in FIGS. 5, 6, and 10, the stopper pieces 10, 10 provided on the outer surface of the column 5 are the upper surfaces of the foundation 3 around the hole 4 when the column 5 is inserted into the hole 4. And the lower portion of the column 5 below the stopper pieces 10 and 10 is provided so as to be immersed in the hole 4. The filler 9 is formed by the engagement of the stopper pieces 10 and 10. It is filled up to the height from the lower end of both frame members 51, 51 to the attachment position of the stopper piece 10 by the length of the lower region of the column 5 immersing in the hole 4.
Further, the ring-shaped elastic material 11 is stuck and fixed to the outer surface of the column 5 by an appropriate width from directly below the stopper piece 10, and the column 5 is inserted into the hole 4 as shown in FIG. 13. Thus, the ring-shaped elastic material 9 faces the upper end of the hole 4 and is pressed against the inner surface of the hole 4 so that the gap between the inner surface of the hole 4 and the surface of the column 5 is closed. .

The eaves-like elastic material 12 uses a foamed elastic rubber material having good compression and stretchability. As shown in FIG. 9, the eaves portion having a width of about 10 mm is formed in the rectangular opening 12a in which the outer peripheral surface of the support column 5 is fully fitted. It is formed in a rectangular ring shape having a thickness of about 5 mm surrounded by 12b, and is fitted on the outer peripheral surface from the lower end portion of the support column 5 so as to overlap the lower surfaces of the stopper pieces 10,10.
As the saddle-like elastic material 12, it is preferable to use a material in which a synthetic resin rubber foam material is laminated on both the front and back surfaces of a sheet or film made of synthetic resin or nonwoven fabric as a core material layer. Since the synthetic resin rubber foam material is flexible, when the hook-shaped elastic material 12 is formed by itself, the hook-shaped elastic material 12 may be twisted or folded during construction. If the core-like elastic material 12 has a structure in which a synthetic resin rubber foam material is laminated on the core material, moderate rigidity is imparted together with elasticity, and the hook-like elastic material 12 is not easily twisted or broken during construction. It is possible to attach it exactly to the position, and there is no gap caused by twisting or bending.

The support column 5 has an outer shape that is rigid enough to support the wall surface panel 6 without dropping from the groove 5a when a water pressure of a planned scale acts on the water blocking wall due to overflow from the sewer due to heavy rain. The hole 4 is provided with a size, and the pillar 4 can be inserted into the opening 41a even when a water pressure of an internal shape and a planned scale that allows the pillar 5 to be inserted easily acts on the surface of the wall panel 6 in the vertical direction. 5 is provided at a depth that does not fall down.
For example, in the case where a steel frame material 51 having a thickness of 2.3 mm is combined and the support 5 is provided with an outer dimension of a width of 90 mm and a depth of 75 mm at the lower part of the hole 4, the inner dimension of the opening 41 a of the hole 4 is 95 mm. If it is provided at about 80 mm, the insertion operation of the support column 5 can be performed easily and reliably, and the depth of the hole 4 is set to about 250 mm, and the lower part of the support column 5 is provided to a depth of about 200 mm into the hole 4. In this case, there is no possibility that the column 5 will fall even if water pressure acts on the wall surface panel 6. If a ring-shaped elastic material 11 having a thickness of about 2 to 5 mm is fixed to the entire circumference of the lower part of the column 5 having the outer dimensions, the ring-shaped elastic material 11 is compressed when the column 5 is inserted into the hole 4. As a result, the gap between the hole 4 and the support column 5 is surely closed by being pressed into contact with the inner surface of the upper end of the hole 4.
Further, when the column 5 is formed in the outer dimensions, the bowl-shaped elastic material 12 is formed by providing the opening 12a with the same dimension as the outer dimension of the lower part of the column 5 so that the bowl-shaped elastic material 12 is formed. Is fitted in close contact with the outer surface of the support column 5, and when the support column 5 is inserted into the hole 4, the hook-shaped elastic material 12 is inserted into the gap between the inner surface of the hole 4 and the surface of the support column 5 at the upper end of the hole 4. Fits, and the gap between the connecting portion of the support column 5 and the hole 4 can be reliably closed.

  As shown in FIG. 11, the holes 4 and 4 provided on both sides of the entrance / exit of the structure 2 are cored on the foundation 3 next to the structure 2, and the mold 41 is installed in the hole. Formed. At this time, the mold 41 is installed so that the distance (L) between the structure 2 and the structure 2 is about 20 mm, and is attached to the peripheral side portion of the column 5 when the column 5 is inserted into the hole 4. The material 7 is provided so as to be crushed to a thickness of about 20 mm and press-contacted to the outer surface of the structure 2.

  And the support | pillar 5 is each inserted in the hole parts 4 and 4 installed in the both sides of the entrance / exit of the structure 2, and the stopper pieces 10 and 10 of the support | pillar 5 are engaged with the opening upper end of the hole part 4 on the foundation 3 The support 5 is made upright, and the side ends of the wall surface panel 6 are fitted and supported in the recessed grooves 5a of the both supports 5 and 5, and the plurality of wall surface panels 6 are attached in a multi-tiered manner. An emergency water stop wall can be constructed on the foundation 3 facing.

The column 5 and the hole 4 are formed in such a size that an appropriate gap is formed between the column 5 and the inner surface of the hole 4 when the column 5 is inserted into the hole 4. The column 5 can be inserted into the portion 4 by an easy operation.
Further, when the support column 5 is inserted into the hole portion 4, the elastic material 7 attached to the peripheral side portion of the support column 5 is crushed and closely bonded to the outer surface of the structure 2 as shown in FIG. The gap between the column 5 and the structure 2 is completely closed by the elastic material 7, and water does not enter the inside of the water blocking wall from between the two members. Since the elastic material 7 has good stretchability and compressibility, even if the outer surface of the structure 2 is an inclined surface or uneven, the elastic material 7 has a structure as shown in FIG. It can be compressed and deformed into a shape along the outer surface of the object 2 and joined, and the gap between the support column 5 and the structure 2 can be reliably closed to maintain watertightness.

  In addition, as shown in FIG. 13, the ring-shaped elastic material 11 fixed to the outer surface of the lower region of the column 5 with the column 5 inserted into the hole 4 has the elasticity of the surface of the column 5 and the hole due to its own elasticity. The gap C between the hole 4 and the column 5 at the upper end of the hole 4 is formed by shrinking and press-fitting between the inner surface of the column 4 and the outer surface of the column 5 and the inner surface of the hole 4. The ring-shaped elastic material 11 is completely closed. Therefore, when the water blocking wall is installed on the foundation 3, the water accumulated outside the water blocking wall leaks into the water blocking wall through the gap C between the hole 4 and the column 5. In addition, the inside of the lower region of the column 5 immersed in the hole 4 is filled with the filler 9 to close the gaps in the frame members 51 and 51, so that the water that has entered the hole 4 Does not leak through the inside of the column 5.

Furthermore, the hook-shaped elastic material 12 stacked on the lower side of the stopper pieces 10 and 10 is joined to the periphery of the upper end of the hole portion 4 as the stopper pieces 10 and 10 are engaged with the upper end of the hole portion 4. At the same time, the flange-like elastic material 12 is pressed downward and compressed at the lower end of the wall surface panel 6 installed between the lower surface of the stopper pieces 10 and 10 and the columns 5 and 5, and the surface of the column 5 at the upper end of the hole 4 is compressed. And tightly fitting into the gap between the hole 4 and the inner surface of the hole 4, the gap between the connection part of the column 5 and the hole 4 is sealed, and the water stoppage of the connection part can be increased.
Since the bowl-shaped elastic material 12 is deformed and joined along the peripheral shape of the upper end of the hole 4 by its own elasticity, the upper surface of the foundation 3 on which the hole 4 is opened is uneven or pebbles are sandwiched between them. Even if it is tightly bonded to the periphery of the upper end of the hole 4, and the load due to water pressure is concentrated on the connection portion of the column 5 with the hole 4, the position of the column 5 is biased in the hole 4. The hook-shaped elastic material 12 is deformed following the bias of the support 5 and is kept in close contact with the gap between the surface of the support 5 and the inner surface of the hole 4. There is no gap at the connection site, and water leakage from the connection site can be effectively prevented.

14 and 15 show a form in which a water blocking wall is installed along the opening / closing door 21 of the entrance of the building, which is the structure 2, using the support column 5. FIG.
Specifically, the hole 4 is provided on the foundation 3 along the door opening / closing door, in the vicinity of the left and right frame parts 22 and 22 and in the middle of the foundation 3 at a position between them. When there is a risk of the inside of the building being inundated, the support column 5 is inserted into the holes 4 and 4 provided in the vicinity of the left and right frame parts 22 and 22, and the cross-section of the hole 4 provided at the intermediate position is inserted into the hole 4. A pair of frame-shaped frame members 51, 51 are fixed to each other and columns 5A having concave grooves 5a on both left and right sides are inserted to stand upright on each foundation 3, and between the left and right columns 5, 5 and the central column 5A. A water stop wall is formed outside the open / close door 22 by attaching the wall panel 6 to the column 5 and supporting it with the support columns 5 and 5A.
And as FIG. 15 shows, the elastic material 7 of the support | pillar 5 is closely_contact | adhered to the outer surface of the frame part 22 which surrounds the opening-and-closing door 21 in a compressed state, and it prevents that water penetrates into the inside of a water stop wall. It prevents the occurrence of a situation where the inside is flooded. Although not shown, the lower part of the support 5 </ b> A that is immersed in the hole 4 is formed in the same manner as the support 5.
