Description

The present invention relates to a concrete floor forming member for forming a concrete floor at a building entrance or the like, and more particularly to a concrete floor forming member capable of forming a space under a concrete floor.

As a general structure between entrance soils of conventional houses, backfilling soil for raising is piled up in an area between entrance soils surrounded by a cloth foundation standing on a solid foundation, and concrete is placed on top of it. A layer is formed, and a tile is stuck on it. In such a conventional structure between entrance soils, the construction period takes a long time, and white ants invade from a slight gap formed on the joint surface between the solid foundation and the fabric foundation, and the entrance ridge passes through the backfill soil. There is a risk of eating damage.
Therefore, the present applicant has previously proposed a member for forming a concrete floor that can form a space by forming a space under the soil without using backfill soil (see Patent Document 1).

The member for forming a concrete floor of Patent Document 1 has a plate-like panel portion and a hollow cylindrical column base portion extending downward from a through hole provided in the panel portion. The concrete floor and the concrete pillar are integrally formed by pouring fresh concrete from the bottom. In addition, the concrete floor forming member has a hollow cylindrical connecting member that can be connected to the lower end of the column base, and the height of the panel portion is constructed by connecting the connecting member. It can be adjusted according to the location.

2 (a) is a left side view of the panel member shown in FIG. 1, FIG. 2 (b) is a right side view thereof, and FIG. 2 (c) is a view of the panel member shown in FIG. It is AA sectional view.

3A is a front view of the panel member shown in FIG. 1, and FIG. 3B is a cross-sectional view taken along line BB of the panel member shown in FIG.

As shown in FIG. 1, FIG. 2A and FIG. 2B, the panel member 10 is a plane having a shape in which a substantially rectangular plane 11a and a plane 11b are overlapped with each other in a state shifted in the vertical direction in plan view. Part 11, an outer wall 12 a provided so as to surround the outer peripheral upper part of the flat surface 11 a and an outer wall 12 b provided so as to surround an outer peripheral lower part of the flat surface 11 b, and a rib 14 (in the horizontal direction) connected to the outer wall 12 The horizontal ribs 14a formed and the vertical ribs 14b formed in the vertical direction) are arranged on the panel member 10 at substantially equal intervals, and are in contact with the ribs 14 and the six through holes 20 passing through the panel member 10 vertically. A drainage portion 30 having a plurality of drainage through holes 31 provided at a position is provided.

As shown in FIG. 1, four receiving portions 33 are provided on the upper side surface of the flat surface 11a so as to extend in the horizontal direction (vertical direction in FIG. 1) from the upper outer wall 12a. The receiving portion 33 has a hollow column shape with an open front side surface, and a guide 34 extending in the horizontal direction is provided inside.

Further, as shown in FIG. 3 (a), the lower surface of the plane 11b (the front surface in FIG. 3 (a)) is arranged horizontally from the lower outer wall 12b (the front side in FIG. 3 (a)). Four insertion portions 35 extending in the direction) are provided. The insertion portion 35 has a columnar shape, and a guide groove 36 is provided on the outer side surface.

The four insertion portions 35 correspond to the four receiving portions 33, respectively. When the plane 11a of another panel member 10 is overlapped on the plane 11b of one panel member 10 and is slid in the horizontal direction, 4 The two insertion portions 35 are inserted into the corresponding four receiving portions 33, and the two panel members 10 are connected. Since the insertion portion 35 and the receiving portion 33 are connected in the horizontal direction, it is possible to reduce the deviation in the height direction when the plurality of panel members 10 are connected.

As shown in FIGS. 1, 2A, 3A and 3B, the left side surface of the plane 11b has three male engaging portions 38 protruding from the left side surface. Guides 40 that are provided at equal intervals and extend in the vertical direction (the frontward direction in FIG. 1) are provided inside.

The female-side engaging portion 42 can be engaged.

Further, as shown in FIG. 1, the panel member 10 includes water drain holes (drain holes) 15 composed of a large number of small holes.

The plane 11a and the plane 11b are overlapped (engaged) in a shifted state when the panel member 10 is connected in the vertical direction on another plane 11b of the one panel member 10. This is because the flat surface 11a of the member 10 can be overlapped. At this time, since the flat surface 11b exists below the joint portion, when concrete is formed on the panel member 10, it does not leak downward. .

That is, only one of the outer wall 12 a and the outer wall 12 b is erected on the outermost peripheral portion of the panel member 10, and the step portion 13 is formed on the outermost peripheral portion of the panel member 10. By superimposing the step parts 13, a large number of panel members can be combined. Therefore, the area of the panel part can be enlarged at the construction site, and a panel part with a large area corresponding to the shape of a wide concrete floor can be easily obtained. Can be formed.
The height of the outer wall 12 is desirably high enough to withstand the weight of the concrete placed on the panel portion, and this height varies depending on the material and the shape of the panel portion. About 60 mm is desirable.

The horizontal ribs 14a and the vertical ribs 14b formed so as to be connected to the outer wall 12 are formed so as to intersect with each other. Therefore, the strength of the panel member 10 itself is high, and the adhesiveness with the concrete is excellent. The concrete floor 2 (see FIG. 8) has sufficient strength.
In the panel member 10 shown in FIG. 1, the horizontal ribs 14 a and the vertical ribs 14 b are formed in the horizontal direction and the vertical direction, but the rib forming direction is not limited to the above-described embodiment, and one or both of them. May be formed so as to be inclined.

It can be set arbitrarily such as a hexagon.

The drain holes 15 are respectively provided in the respective lattice portions partitioned by the ribs 14, and can effectively discharge moisture contained in the concrete poured into the respective lattice portions.
The shape of the drain hole 15 is not limited to the shape shown in FIG. 1 and can be arbitrarily set to a circle, a rectangle, a square, a circle, a rhombus, an ellipse, a triangle, a hexagon, and the like.
In addition, the number of drain holes 15 provided in each lattice portion is not limited to one for each lattice portion, and a plurality of drain holes 15 may be provided.

As shown in FIGS. 1 and 3B, a hollow cylindrical fixed column base 21 extending downward from the upper surface of the panel member 10 is formed in the through hole 20. The fixed column base 21 is formed integrally with the panel member 10 and is fixed to the through hole 20. A screw groove 22 is formed on the inner peripheral surface of the lower portion of the fixed column base 21, and a length adjusting column base 50 (see FIGS. 5 and 6) can be screwed thereto.

4 (a) is an enlarged plan view of a portion indicated by C in FIG. 1, FIG. 4 (b) is an enlarged horizontal sectional view thereof, and FIG. 4 (c) is shown in FIG. 4 (a). It is the DD sectional view taken on the line in drawing.

As shown in FIG. 4A to FIG. 4C, the drainage portion 30 has a rectangular drainage through hole 31 whose one side is a part of the rib 14 and the drainage through hole 31. The top plate 32 is formed so as to be perpendicular to the ribs 14.

In the drainage part 30, the top plate 32 exists just above it so that the through-hole 31 for drainage may be covered. Therefore, when the concrete floor 2 (see FIG. 8) is placed on the panel portion 10, the low-viscosity water passes through the drainage through-hole 31 faster than the other components having a high viscosity. By this action, the moisture contained in the concrete floor 2 can be efficiently discharged under the panel.

In addition, since a part of the solidified concrete is solidified at the lower part of the top plate 32, when a movement to lift the solidified concrete is applied, the solidified concrete at the lower part of the top plate 32 is caught by the top plate 32. The concrete can be prevented from slipping.

The shape of the drainage through hole 31 is not limited to the shape shown in FIGS. 4A to 4C, and may be arbitrarily set to a square, a circle, a rhombus, an ellipse, a triangle, a hexagon, and the like in addition to a rectangle. Is possible.

Further, if the shape does not allow the concrete to flow out, the shape of the drainage through hole 31 and the shape of the top plate 32 do not have to be the same, for example, the shape of the drainage through hole 31 is rectangular, The shape of the top plate 32 may be an ellipse.

The distance between the drainage through hole 31 and the top plate 32 is desirably a minimum distance having sufficient drainage capacity, and specifically, about 2 mm to 10 mm is desirable.

The material of the panel member 10 is not particularly limited, and examples thereof include metal materials and resin materials. Although it does not specifically limit as a metal material, For example, stainless steel, cast iron, etc. can be mentioned. Ceramic may be used. The resin material is not particularly limited. For example, polypropylene, polyethylene, acrylonitrile / butadiene / styrene resin (ABS), polyvinyl chloride, nylon and other synthetic resins, natural rubber (NR), and styrene / butadiene rubber. Examples thereof include rubber materials such as (SBR) and chloroprene rubber (CR). These materials may be used alone or in combination of two or more. In addition to the above resin material, for example, a mixture of fillers such as calcium carbonate and glass fiber may be used.
Of these, a hard material is desirable because it needs to be strong enough to withstand the weight of the concrete placed on the panel.

When resin is used as the material of the panel member 10, the panel member 10 having the shape shown in FIGS. 1 to 4 can be easily formed by injection molding. Moreover, since it can cut | disconnect to arbitrary dimensions in a construction site, the dimension change and shape change of the whole panel part can be easily performed according to a site. Therefore, the panel member 10 is preferably made of a resin as a main component.

The thickness of the material constituting each part of the panel member 10 is desirably a thickness that can sufficiently withstand the weight of the concrete placed on the panel, and this thickness depends on the material and the shape of the panel portion. Usually, about 1 to 5 mm is desirable.

The screw groove 52 corresponds to the screw groove 22 formed on the inner wall of the fixed column base 21, and the length adjusting column base 50 is engaged by rotating the screw groove 52 in mesh with the screw groove 22. Can be screwed onto the fixed column base 21. Since the length adjusting column base 50 is screwed onto the fixed column base 21, the entire length of the column base 59 (see FIG. 8) can be finely adjusted according to the amount of rotation.

As shown in FIG. 6, four support columns 54 extending in the height direction from the upper surface to the middle are formed on the inner wall of the length adjusting column base 50. Strength is made strong.

A plurality of U-shaped cutouts 56 are provided below the screw grooves 52 in the length adjusting column base 50, and a stopper 58 protruding outward is provided between the cutouts 56. It has been. The stopper 58 has a rib shape longer than the height of the notch 56, and even when the length adjusting column base 50 is screwed to the fixed column base 21 to the end, the fixed column base The notch 56 is prevented from being hidden behind the fixed column base 21 by colliding with the lower portion of the base 21. Moreover, since the stopper 58 has a rib shape, it is possible to improve the strength of the lower end portion of the length-adjusting column base 50 that is most loaded when ready-mixed concrete is poured. The notch 56 can discharge the moisture contained in the ready-mixed concrete poured into the column base, and can accelerate the solidification of the concrete. The width of the notch 56 can be arbitrarily set, but is preferably about 6 to 18 mm.
In the present embodiment, the case where the stopper 58 has a rib shape has been described. However, in the present invention, the shape of the stopper is such that the notch is not hidden by having a protrusion at a position above the notch 56. As long as it is possible, it is not limited to this example.

The material for the length adjusting column base 50 is not particularly limited, and examples thereof include a metal material and a resin material. Although it does not specifically limit as a metal material, For example, stainless steel, cast iron, etc. can be mentioned. Ceramic may be used. The resin material is not particularly limited. For example, polypropylene, polyethylene, acrylonitrile / butadiene / styrene resin (ABS), polyvinyl chloride, nylon and other synthetic resins, natural rubber (NR), and styrene / butadiene rubber. Examples thereof include rubber materials such as (SBR) and chloroprene rubber (CR). These materials may be used alone or in combination of two or more. In addition to the above resin material, for example, a mixture of fillers such as calcium carbonate and glass fiber may be used.
Among these, a hard material is desirable because it needs to have a strength that can sufficiently withstand the weight of the concrete placed on the panel portion.

When resin is used as the material for the length adjusting column base 50, the length adjusting column base 50 having the shape shown in FIGS. 5 and 6 can be easily formed by injection molding.

Fig.7 (a) is a top view which shows typically the L-shaped edge material which can be used suitably when forming a concrete floor using the member for concrete floor formation of this invention, FIG.7 (b) ) Is a right side view thereof. This L-shaped edge member is provided on at least a part of the outer periphery of the panel member, and serves as a weir that prevents the ready-mixed concrete from flowing out when the ready-mixed concrete is poured onto the panel member.

The L-shaped edge member 60 is composed of two strip-like plate-like bodies 61a and 61b, and the plate-like body 61a and the plate-like body 61b are vertically coupled so that their long sides are in contact with each other. Yes.

As will be described in detail later, the L-shaped edge member 60 has a rising base 104 (see FIG. 5) in which the plate-like body 61a is disposed on the panel portion 10 and the other plate-like body 61b is in contact with the panel portion 10. 8) and the like. Thereby, even if a clearance gap arises between the surrounding walls when the panel member is placed, it is possible to prevent the concrete from flowing out.

The material of the L-shaped rim material of the present invention is not particularly limited, and examples thereof include metal materials and resin materials. Although it does not specifically limit as a metal material, For example, stainless steel, cast iron, etc. can be mentioned. Ceramic may be used. The resin material is not particularly limited. For example, polypropylene, polyethylene, acrylonitrile / butadiene / styrene resin (ABS), polyvinyl chloride, nylon and other synthetic resins, natural rubber (NR), and styrene / butadiene rubber. Examples thereof include rubber materials such as (SBR) and chloroprene rubber (CR). These materials may be used alone or in combination of two or more. In addition to the above resin material, for example, a mixture of fillers such as calcium carbonate and glass fiber may be used.
Among these, even if the surrounding wall is uneven, it is possible to follow it, so that a soft material is desirable.

When a resin is used as the material of the L-shaped edge material of the present invention, the L-shaped edge material can be easily formed by injection molding. Moreover, since it can cut | disconnect in arbitrary dimensions at a construction site, the height and width | variety of an L-shaped edge material can be changed easily. Therefore, it is desirable that the L-shaped edge material of the present invention is composed mainly of a resin.

The length of each side of the L-shaped rim material is not particularly limited, but it is desirable that the length be equal to or higher than the height of the concrete floor to be placed. This is because the concrete overflows from the L-shaped edge material.

The thickness of each side of the L-shaped rim material is not particularly limited, but a thickness that is sufficiently strong to withstand the weight of the concrete placed on the panel portion is desirable.
This thickness varies depending on the material and shape of the L-shaped rim material, but is generally preferably about 0.5 to 5 mm.

Next, the structure of the surrounding area such as the entrance formed using the concrete floor forming member of the present invention and the construction method thereof will be described.
Although the method for forming the soil surrounding portion is not particularly limited, it is desirable to adopt the following method.

FIG. 8 is a cross-sectional view schematically showing an example of the structure of the soil surrounding portion.
The foundation used here is a so-called solid foundation.

When building a solid foundation, after digging down the outer shell and inner shell of the part where the building is to be built to a predetermined width, flatten it, and then apply the cracked stone 101 to the whole part including the part where the building is built and its outer edge. Large stones are laid, and gravel called crushed stone is laid between cracked stones 101.
Next, a concrete called a discarded concrete 102 is placed on the cracked stone 101. The abandoned concrete 102 refers to the underlying concrete that corresponds to the bottom of the foundation. The discarded concrete 102 is made as flat as possible. On the discarded concrete 102, a reinforcing bar (not shown) substantially parallel to the discarded concrete 102 and a reinforcing bar (not shown) perpendicular to the discarded concrete 102 are provided.

Furthermore, after forming concrete 103 (hereinafter referred to as a solid foundation) including a reinforcing bar thereon, a rising portion 104 (hereinafter referred to as a rising foundation) formed on the solid foundation 103 is not illustrated. A formwork is erected and fixed to the solid foundation 103.

After this, raw material concrete (hereinafter referred to as ready-mixed concrete) is poured into a mold and left to solidify for several days, thereby forming the rising foundation 104. Thereafter, the mold is removed, and mortar (not shown) is applied to the outer surface of the rising foundation 104 exposed to the outside, so that makeup is applied to the outer surface of the foundation portion, and the foundation portion construction process is completed.
The above is the basic placing process.

The material of the water-stop sheet is not particularly limited as long as the amount of water (moisture) permeation is extremely small. For example, polyvinyl chloride (PVC), various polyolefin-based synthetic resins, and the like can be used. In particular, a soft material is desirable in the present invention. Moreover, in this invention, it is desirable that the water stop material is a soft plate-like body injection-molded into an L shape. Since the waterproof sheet 115 is affixed, even if a gap is generated at the boundary between the solid foundation 103 and the rising foundation 104, it is possible to remarkably prevent water from entering the lower space 121 between the soil from this gap. . Moreover, even if a gap is generated at the boundary between the solid foundation 103 and the rising foundation 104, it is possible to prevent white ant prevention from entering the space below the soil from the gap.

Next, a soil dam plate installation step is performed.
In this step, a floor bundle 114 whose height can be adjusted is arranged at a location that becomes a boundary between the soil 120 and the floor 122, and the soil dam plate 116 is placed thereon. The soil barrier plate 116 is L-shaped in cross section having a horizontal surface 116 a and a vertical surface 116 b extending downward, and is placed so that the horizontal surface 116 a is positioned on the floor bundle 114. At this time, the height of the floor bundle 114 is adjusted so that the upper surface of the rising foundation 104 and the upper surface of the soil barrier plate 116 have the same height. A conventionally known one can be used as the height-adjustable floor bundle 114, and examples thereof include a floor bundle described in Japanese Patent No. 3394644. Note that when the concrete floor forming member 1 is installed in the soil 120, the soil barrier plate 116 has the vertical surface 116b facing the side surface of the panel member 10 of the concrete floor forming member 1, and the upper portion of the vertical surface 116b is the panel. What protrudes above the upper surface of the member 10 is employ | adopted.

Next, a basic packing placement process is performed.
In this process, a shield-type foundation packing 118 is laid on the entire circumference of the foundation 120 (around the entrance). Specifically, the foundation packing 118 is laid on the upper surface of the rising foundation 104 and the upper surface of the dirt barrier plate 116. The shielding-type basic packing refers to a basic packing in which a through hole for ventilation is not formed on the side surface, and a conventionally known one can be adopted. Examples of the shielding-type basic packing include those disclosed in JP-A-2005-290906.

Next, a base mounting process is performed.
In this step, the base 112 is placed on the upper surface of the foundation packing 118.

Next, a concrete floor forming member installation step is performed.
In this step, the concrete floor forming member 1 is formed by combining the plurality of panel members 10 (see FIGS. 1 to 4) and the length adjusting column base 50 (see FIGS. 5 and 6), and the soil 120. Install so as to cover the entire surface.

While installing. Further, at this time, the length adjusting column base 50 is rotated as necessary to adjust the upper surfaces of the plurality of concrete floor forming members 1 to be flush with each other.

When connecting a plurality of members for forming a concrete floor, the order of the connection in the horizontal direction and the connection in the vertical direction is not particularly limited, but it is desirable to connect in the horizontal direction first and then connect in the vertical direction. This is because if the connection is made in the horizontal direction first, then the connection in the vertical direction can be made by shifting the concrete floor forming member in the horizontal direction without lifting it. When the concrete floor forming member 1 is installed, the vertical surface 116 b of the soil barrier plate 116 faces the side surface of the panel member 10 of the concrete floor forming member 1, and the upper portion of the vertical surface 116 b is higher than the upper surface of the panel member 10. Will also protrude upwards.

Next, an edge material placing process is performed.
In this step, the L-shaped edge member 60 is attached so as to cover the boundary between the upper surface of the panel member 10 and the vertical surface 116b of the soil barrier plate 116 or the rising foundation 104. By attaching the L-shaped edge member 60, it is possible to eliminate a gap between the concrete floor forming member 1 and the soil barrier plate 116, and to prevent white ants from entering.

The number of L-shaped edge members 60 and the length of the installation portion can be adjusted as necessary, but it is desirable to provide the L-shaped edge member 60 so as to surround the entire outer periphery. This is because even if a gap is generated between the concrete floor forming member and the surrounding wall, it is possible to prevent the concrete from flowing out. To attach the L-shaped edge material so that it covers the surrounding members such as the soil dam plate and the rising foundation, a double-sided tape is attached to the part where the L-shaped edge material is adhered, or it is bonded using an adhesive. The method to do can be adopted.

Next, a concrete placing process is performed.
That is, ready-mixed concrete is poured into the panel member 10 of the concrete floor forming member 1 and the column base portion 59. At this time, a necessary amount of ready-mixed concrete is poured so that the concrete floor 2 after solidification has a thickness of about 30 to 100 mm. In addition, the concrete pillar 3 is formed in the column base part 59. Since a void portion is formed below the panel member 10, the amount of concrete used can be reduced as compared with a conventional general construction method. Since the void portion is formed below the concrete floor forming member 1, the space below the soil can be kept in a dry state, and corrosion of each member due to moisture and growth of mold can be suppressed.

After the concrete has solidified, the rivet installation process is performed.
In this step, the saddle material 111 is attached to the side surface of the base 112. Thereafter, the floor material 124 is attached to the floor 122 portion.

Next, the armpit parting attachment process is performed.
In this step, by attaching a surface 126 a of the underarm closing 126 to the lower surface of the rising underlay 111, the undercover 126 is attached to the undercover 111. Thereafter, the tile base mortar 127 is hit, and the tile 128 is laid thereon. A space 111 a can be formed under the raised saddle 111 because the underlay 126 is attached to the lower surface of the raised saddle 111.
Since the space 111a is formed, it is possible to prevent the moisture of the concrete from spreading and to prevent the raised brazing material 111 from being wet and to be hardly corroded.

The concrete floor 2 may be provided with a drain outlet for discharging to the outside when water accumulates on the upper surface.

Through the above steps, the structure 300 around the soil is formed.

The concrete floor forming member according to the present invention has been described above. However, the concrete floor forming member of the present invention is not limited to the above-described example, and is appropriately designed within the range satisfying the configuration of the present invention. It is possible to make changes.
