2. Description of the Related Art In an underground structure in which an underground space is defined by an underground wall made of a concrete skeleton, a phenomenon in which groundwater seeping out from the interface of the underground soil flows out to the indoor side through cracks in the concrete skeleton. Occurs. For this reason, conventionally, a drainage space is provided between the concrete frame and the indoor inner wall by the double wall structure, and groundwater flowing out to the indoor side through the concrete frame is collected in the drainage space, and then flows downward from there. Underground wall drainage structures have been used to drain water.

However, the above-described underground wall drainage structure requires a double wall structure that constitutes a drainage space between the concrete frame and the indoor inner wall, which complicates the construction method. A dead space, which is a space for drainage, occurs, and the effective utilization rate of the space decreases. The present applicant has solved the above-mentioned problems in the conventional underground wall drainage structure, and has an object to provide an underground wall drainage structure that drains groundwater without requiring a large dead space. A water-permeable sheet is attached to the one side of the panel body made of a closed-cell foam material in which a concave drainage flute is formed on one side, on the indoor side wall surface of the concrete skeleton forming the underground wall. The underground wall drainage panel is mounted with the surface on the side of the permeable sheet in contact with the indoor side wall surface of the concrete skeleton.

SUMMARY OF THE INVENTION The present invention relates to an improved underground wall drainage structure as described above, for example, when a drainage panel is arranged on the surface of a concrete skeleton.
An object of the present invention is to provide an inter-panel exposing member which can easily perform exposing each panel when a plurality of panels are arranged on a substrate. The present invention also aims to further improve the above-described underground wall drainage structure, and more reliably prevents groundwater from seeping into the indoor side from a joint that is a joint between adjacent drainage panels. The present invention provides an underground wall drainage structure that can be installed and is easy to construct.

[0005]

According to the present invention, there is provided an inter-panel facing member for solving the above-mentioned problems, which is used when a plurality of panels are arranged on a substrate at a constant interval (gap). A surface mounting member between panels, the surface mounting member comprising a panel lower surface support member and a panel upper surface pressure contact member screwed to the panel lower surface support member, wherein the panel lower surface support member is connected to an adjacent panel. A base that is sized not to enter the gap (gap) with the panel; and a column that stands upright on the base and that is thick enough to pass through the gap and shorter than the thickness of the panel to be exposed. The panel upper surface pressure contact member has a flat back surface and enters the space (gap) between the adjacent panels. Not big And some cap members, characterized in that it has a screw rod which vertically downward from the back surface of the cap member.

[0006] When a plurality of panels are arranged at a fixed interval (gap) on a substrate having a large area, all panels are arranged in a state in which the side wall surfaces of the panels are in close contact with each other. However, it is not easy to expose the panels, ie, to arrange the surfaces of all panels as uniform flat surfaces. This is especially true when the adhesion between the substrate and the rear surface of the panel is insufficient or when the panel is likely to be warped or twisted.

[0007] According to the present invention, the surface-exposing member between the panels is provided with one lower surface on the back side of the corners of two, three or four panels which are arranged at regular intervals and which are close to each other. The corners are placed on the base of the support member so that they are simultaneously placed. Then, in this state, the panel upper surface pressure contact member is screwed into the support of the lower surface support member. Even if there is a deviation in the height of the corners of each adjacent panel due to warping or twisting, each corner is gradually pushed down by the back surface of the cap member which is the panel upper surface pressure contact member, and finally each corner is The surface of the panel is made uniform and flat. The same is done at all panel corner assemblies where face-up is required, and multiple panels are leveled as a whole on the substrate.

[0008] When the adhesion between the substrate and each panel becomes firm and peeling or the like does not occur, the panel upper surface pressure contact member is removed. Thus, a structure in which the entire surface of the panel is flat on the substrate is obtained. A panel in which the panel to be exposed is composed of a panel body and a surface material laminated on the surface, and a notch is formed on a side of the side wall surface around the panel body where the surface material is laminated. In the case where the surface is exposed, it is effective to use a column having a second base portion that can enter the cut and has a flat upper surface formed on the support of the panel lower surface support member. . At this time, the height of the upper surface of the second base is
At the time of surface appearance, the back surface of the surface material is set to a height at which the back surface comes into contact.

In a preferred aspect, a projection is formed on the upper surface of the second base so as to enter a space (gap) between the adjacent panels. By providing such projections, it is easy to hold adjacent panels at a fixed interval, and when a connecting tool for connecting adjacent panels at a fixed interval is used. In addition, it is possible to position the connecting tool.

According to the present invention, as an example of a structure constructed using the above-mentioned panel-facing member, the substrate is a concrete body forming an underground wall, and the panel has a concave drainage surface on one surface. A drain panel in which a water-permeable sheet is attached to a surface of the panel body made of a foamed material in which a drain groove is formed, on a surface on a side where the drain groove is formed, and an indoor surface side of a concrete frame forming the underground wall. In addition, the plurality of drainage panels, through an appropriate connector, such that the water-permeable sheet is in contact with the indoor surface side of the concrete skeleton, and the adjacent side wall surface and the side wall surface of the adjacent drainage panel The lower surface support member of the surface-appearing member is disposed at a position where the corners of the adjacent drainage panels are gathered at a predetermined interval therebetween, and the panel upper surface pressure contact member is provided. The corners of each drainage panel are simultaneously pressed from the front side to expose each drainage panel, so that the adjacent drainage panels are adjusted to be substantially coplanar. Underground wall drainage structure,
Is disclosed.

Usually, in order to make the above-mentioned underground wall drainage structure, a space for concrete placement is formed by installing two molds in the ground using a separator or the like, and concrete is poured there. And a concrete skeleton is formed. At this time, one of the molds in which a plurality of the above-mentioned drainage panels are arranged in a plane is used, and the drainage panel is integrated with the concrete frame by solidification of the cast concrete.

At the stage of installing the formwork in the ground, arranging and holding a plurality of drainage panels in a state in which a fixed interval is provided between opposing side wall surfaces of adjacent drain panels.
In addition, it is not easy to expose the surfaces of the plurality of drainage panels to substantially the same surface, and it is also not easy to secure an appropriate connector used for maintaining an interval at a predetermined position. This is the same even after the concrete is cast and while the concrete is solidified.

Such inconveniences can be easily solved by using the above-mentioned face-out members between panels, for example, when assembling a formwork and assembling a plurality of drainage panels as described above. After the poured concrete is solidified and the drainage panel and the concrete frame are integrated, the panel upper surface pressure contact member is removed, and preferably a sealing material is filled at the position, whereby the underground wall drainage structure according to the present invention is completed. I do.

In a preferred embodiment of the underground wall drainage structure, the drainage panel has a laminated surface material, and a cut is formed on a side wall surface around the panel body where the surface material is laminated, In the notch,
A second base formed on a support of the panel lower surface support member enters, and a flat upper surface supports the back surface of the surface material.

[0015] In the underground wall drainage structure according to the present invention, there is no particular limitation on the shape of the connector used to arrange adjacent drainage panels at a fixed distance between the opposing side walls. However, it is a preferable embodiment to use a long partition plate having at least a leading edge in a U-shaped folded portion, in which case, the adjacent drain panels are connected to one drainage panel. The side wall surface of the panel is arranged so as to contact the partition plate on the side opposite to the folded portion of the connecting device, and the side wall surface of the other drainage panel is arranged in contact with the folded portion of the connecting device. Thereby, a continuous space closed on the indoor side by the U-shaped folded portion is formed between the opposed side wall surfaces of the adjacent drainage panels, and the space functions as a water passage.

In the underground wall drainage structure according to the present invention, groundwater leaking into the indoor side from the concrete frame forming the underground wall passes through the water-permeable sheet and enters the concave drainage groove formed in the panel main body. Therefore, the above-mentioned indoor side flows into a closed continuous space, and from there, flows out to a predetermined drainage channel. Therefore, it is possible to reliably prevent the groundwater from seeping into the indoor side from the joint, which is a joint between the adjacent drainage panels.

In a preferred aspect, the drainage panel has a surface material laminated thereon, and a cut is formed in a side wall surface around the panel body where the surface material is laminated, and the cutout is formed in the cutout. A second base formed on a support of the panel lower surface support member enters, and the flat upper surface supports the back surface of the surface material. The surface material is optional, but it is preferable to laminate the non-combustible plate members by means such as bonding. Examples of the non-combustible plate member include a gypsum board, a fiber reinforced cement plate, a metal plate, and the like, and a composite plate obtained by combining these can also be used.

There is no particular limitation on the foaming material used for the panel body of the drainage panel according to the present invention, but a styrene resin foam is preferred because it has closed cells and a small water absorption. The styrene-based resin may be a homopolymer of a styrene-based monomer or a copolymer thereof.
The styrene monomer may include styrene derivatives such as methylstyrene and ethylstyrene in addition to styrene. Further, the copolymer may contain at least 50% by weight of a styrene-based monomer, and the remainder may be composed of another monomer. Other monomers include methyl methacrylate, acrylonitrile, and maleic anhydride. Acids and the like can be mentioned. In addition, the styrene-based resin further includes a blend obtained by mixing another resin with a homopolymer or a copolymer. Other resins include polyethylene and synthetic rubber. Preferably, the blend comprises at least 50% by weight of polystyrene.

As the water-permeable sheet according to the present invention, any material having water permeability can be used.
In particular, alkali-resistant polyester, polypropylene,
In the case of a nonwoven fabric such as polyethylene or rayon, sufficient corrosion resistance can be imparted to groundwater flowing out from the concrete body to the indoor side, so that the object can be achieved for a long time.

It is a flat plate having a width of about 6 mm, and has a number of notches 68 in the longitudinal direction. A side edge of the substrate 61 on the side where the U-shaped folded portion 64 is located is a sharp protruding edge 69 directed upward (toward the U-shaped folded portion 64).

Next, an embodiment in which the drainage panel 30 is connected and arranged by using the above-described connecting tool 60 will be described. FIG. 9 is a cross-sectional view taken along line IX-IX in FIG. 7, and shows a horizontal connection state of two drainage panels 30, 30 located in the vertical direction. FIG. 10 is a cross-sectional view of FIG.
It is sectional drawing by a line, and has shown the connection state in the perpendicular direction of two drainage panels 30 and 30 located in a left-right direction.
As can be seen from FIGS. 9 and 10, in the underground wall drainage structure according to the present invention, the connection manner of the drainage panels is the same in both the horizontal direction and the vertical direction except for the direction. At the time of construction, two molds are set at predetermined intervals using a vertical end, a horizontal end, a severator, or the like, as usual, to form a driving space for a concrete skeleton serving as an underground wall. As one of the molds, a large number of the drainage panels 30 are connected and arranged by using a connecting tool 60 and a facing member 170 described later.

First, one drainage panel 30 (30
A) is set so that the water permeable sheet 36 side is the space side for placing concrete, and the connecting member 60 is attached to the upper side wall surface thereof. At this time, as shown in FIG. 9, the connecting tool 60 is configured so that the U-shaped folded portion 64 faces the upper surface, and the pressing plate 67 enters the cut 37 formed on the side wall surface of the panel main body 32. And then
The front end portion of the peripheral side wall of the panel main body 32 is fitted between the holding plate 67 and the substrate 61. At the same time, the connector 60 is similarly attached to one vertical side wall surface of the drain panel 30. At this time, as shown in FIG. 10, the connecting tool 60 is vertically erected so that the U-shaped folded portion 64 is on the outside, and the vertical position of the panel main body 32 is set between the holding plate 67 and the substrate 61. The tip of the peripheral side wall in the direction is fitted. Thereby, the drainage panel 30A is assembled as a part of the mold with the upper side and one side side positioned.

Next, another drainage panel 30 is disposed in the horizontal direction.
(30B) is attached. At this time, as shown in FIG. 10, one vertical side wall surface of the drain panel 30 </ b> B to be attached is arranged so as to abut against the U-shaped folded portion 64 of the connecting tool 60. Thereby, between the two left and right drainage panels 30A and 30B, both sides are regulated by opposing side wall surfaces, and the bottom surface (concrete skeleton side) is regulated by the substrate 61 of the connecting member 60, and the upper surface ( On the indoor side), a vertical space Sa regulated by the U-shaped folded portion 64 of the coupling tool 60 is formed.

The lower edge of the U-shaped folded portion 64 is a sharp protruding edge 65 facing outward.
The side edge on the side where the U-shaped folded portion 64 is located is a sharp protruding edge 69 directed upward, and that portion cuts into the water-permeable sheet 36, so that the drain panel 30 is connected to the connecting member 60 side. Is positioned to some extent.

Further, in the upper direction of the drainage panels 30A and 30B, another drainage panel 30 (30C,
30D). At that time, as shown in FIG.
The drainage panels 30C and 30D to be attached are arranged so that the side wall surfaces at the lower ends of the drainage panels 30C and 30D come into contact with the U-shaped folded portion 64 of the coupling tool 60. Thereby, a horizontal space Sb in which four surfaces are restricted is formed between the upper and lower two drainage panels 30A, 30C and 30B, 30D as described above.

The sharp protruding edge 65 of the U-shaped folded portion 64 cuts into the panel body 32,
When the sharp protruding edge 69 of the substrate 61 bites into the water-permeable sheet 36, the side wall surface of the drainage panel 30 on the connecting tool 60 side is also positioned to some extent. Hereinafter, when the drainage panels 30 are similarly assembled in the horizontal direction and the upward direction, all the vertical spaces Sa between the drainage panels form continuous vertical spaces, and each of the vertical spaces Sa between the drainage panels. The horizontal space Sb also forms a continuous horizontal space.

As described above, in this example, the length of each connector 60 is slightly shorter than the length of one side of the drain panel 30. Therefore, as shown by Pa in FIG. 7, the positions where the corners c of the adjacent drainage panels 30 gather (for example, the four drainage panels 30A, 30B, 30).
C, near the corner where the corner c of 30D gathers)
0 does not exist, and the space S in the vicinity thereof does not exist.
Means that the bottom surface (concrete skeleton side) and the top surface (indoor side) are open.

Each drain panel 30 is held with the two side walls fitted between the holding plate 67 of the connecting member 60 and the substrate 61 as described above, but the remaining two side walls are Positioning is performed by cutting the sharp protruding edge 65 of the U-shaped folded portion 64 and the sharp protruding edge 69 of the substrate 61, and it is hard to say that the posture is sufficiently maintained. For this reason, the height of the side wall portions of adjacent drainage panels may be shifted.

As a member for solving the above-mentioned inconvenience, a surface-exposing member 170 according to the present invention is used. As shown in FIG. 11, the facing member 170 is provided with a bottom plate 171 (base).
And an upper plate 172 (second base), and a support 17 connecting the two.
3 as a base member for supporting the lower surface of the panel
77 and a cap member 17 as a panel upper surface pressure contact member
8 basically.

The size of the bottom plate 171 and the upper plate 172 of the base member 177 is the same as that of the adjacent drain panel 30 described above.
And the upper plate 172 is formed on the panel main body 32 of the drainage panel 30 at a position where the connector 60 does not exist at a position where the corners c of the drainage panel 30 are present (a region near Pa indicated by Pa in FIG. 7). The notch 37 has a size that can be accommodated. In addition, the distance between the bottom plate 171 and the upper plate 172 is the distance between the bottom plate 171 and the upper plate 172.
Of the side wall where the cut 37 is formed.

Further, in this example, the upper plate 172 has four projections 174a, 174b, 175a, 175b.
Are formed, and the projections 174a and 174b are 180
突起 The projections 175a and 175b are 180 ° out of phase with each other by 90 °. The one pair of the protrusions 175a and 175b is formed so as to be easily broken by pushing it out with a fingertip. A screw 76 is cut at the tip of the support column 173 so that a screw rod 79 of a cap member 78 similar to the case of the facing member 70 shown in FIG. 1 is screwed.

FIGS. 12 and 13 show XII-X in FIG.
FIG. 12 is a cross-sectional view taken along the line II, showing a state in which the cap member 78 is tightened (FIG. 12) and a state in which the cap member 78 is removed (FIG. 13) with respect to the base member 177 of the surface exposing member 170 (FIGS. 12 and 13). In FIG. 13, the connector 60 is not shown for clarity of illustration). As described above, the surfacing member 170 is used for assembling the drainage panel 30 when assembling the formwork.
Is attached to the position Pa where the corners of the. At that time,
As shown in the drawing, the bottom plate 171 is mounted so as to be closest to the concrete casting space, and at the same time, the upper plate 172 is inserted into the cut 37. Also, protrusions 174a, 174b, 175 formed on the upper plate 172 are provided.
a, 175b enter the gap formed between adjacent drainage panels 30, 30. As a result, the distance (interval) between adjacent drainage panels is ensured, the connector 60 is also positioned, and the bottom surface (open) due to the absence of the connector 60 in the above-described spaces Sa and Sb ( The concrete body side) and the upper surface (indoor side) are closed.

After attaching the base member 177, the cap member 78 is screwed into the support 173. As shown in FIG. 12, by screwing, the vicinity of the corner c of each of the drainage panels 30 (for example, the drainage panels 30A, 30B, 30C, and 30D) is simultaneously pressed down from the surface side,
Finally, it is pressed equally between the upper surface of the upper plate 172 and the back surface of the cap member 178. Thereby, the flatness of the adjacent drainage panels 30 is ensured.

As described above, after the drainage panel 30, the connecting member 60, and the facing member 170 have been assembled and the formwork has been completed, concrete is poured into the concrete placing space and hardened. As shown, the projecting piece 63 provided on the back surface of the connecting tool 60 is integrated with the cast concrete,
The drainage panel 30, the connecting member 60, and the facing member 170 are firmly integrated with the concrete skeleton 20 as an underground wall. Thereafter, the vertical end, the horizontal end, the severator, and the like are removed, and the cap member 178 is also removed.
Finally, a gap (panel) formed on the upper surface of the U-shaped folded portion 64 of the connector 60 and the upper plate 172 of the surface-exposing member 170, that is, on the surface side between the adjacent drainage sheets 30 The underground wall drainage structure according to the present invention is completed by driving a sealing material (not shown) into the joint portion.

In this underground wall drainage structure, the continuous spaces Sa, Sb formed between the opposing side walls of the adjacent drain panels 30, 30 actively function as water passages. Therefore, it is possible to reliably prevent groundwater from seeping into the indoor side from the joint, which is a joint between adjacent drainage panels. Further, the use of the facing member 170 makes it possible to easily secure the flatness of the adjacent drainage panels.

In the facing member 170 shown in FIG.
When the corners c of the four drainage panels 30 are equally placed on the upper plate 172, the pressing force of the cap member 178 acts almost equally on the four drainage panels 30, and the surface is properly exposed. Done. However, at the end portion shown as Px in FIG. 7, there are only two drainage panels 30,
There is a case where the pressing force due to the tightening of the cap member 178 is deviated and the proper surfacing is not performed. In such a case, the four protrusions 174 provided on the upper plate 172 are used.
a, 174b, 175a, and 175b, one of the pair of projections 175a and 175b is pushed down with a fingertip and broken, and then the broken portion is vertically oriented in FIG. Attach. Since there is no vertical projection pair 175a, 175b,
Then, the base member 177 is moved to the drain sheet 30 side (FIG. 7).
To the left), and by tightening the cap member 178 at that position, a stable pressing force can be generated.

The above description is that of the preferred embodiment of the present invention, and there are many other variations. A large number of through holes 66 formed in the partition plate 62 of the connecting tool 60
The connector 60 is provided to improve the flow of groundwater in the vertical direction when the connector 60 is disposed in the horizontal direction, and is not necessarily provided for the connector 60 disposed in the vertical direction. In addition, when the connecting tool 60 can be arranged with an inclination, the through-hole is unnecessary even for a connecting tool arranged in the horizontal direction.

The projecting piece 63 formed on the back surface of the connecting member 60 is not essential and can be omitted. Even when it is provided, it is not limited to a flat plate shape, and may have a shape whose tip is curved. Thereby, a more secure assembling becomes possible. It is not essential to laminate the surface material on the drainage panel,
You may make it laminate | stack as a post-operation at a construction site. Further, in the above example, the reason why the drainage panel is formed in a square shape is that it is convenient to make the connecting tools arranged in the horizontal direction and the vertical direction a uniform length, and depending on the construction environment, a rectangular shape may be used. And may be used after being cut into an appropriate shape at the construction site.

According to the present invention, by using the member for exposing between panels, the exposing (leveling) of a large number of panels arranged on the substrate can be easily performed. Further, in the underground wall drainage structure using the exposed member between panels according to the present invention, the drainage panel attached to the concrete skeleton can be easily exposed (leveled) and the concrete skeleton forming the underground wall can be easily obtained. Groundwater that permeates through the water-permeable sheet into the concave drainage groove formed in the panel body, from there, forms between the opposing side wall surfaces of the adjacent drain panel The groundwater is surely prevented from seeping into the indoor side from the joint, which is the joint between adjacent drainage panels, because it is actively flowed through the continuous space.
