Description

The present invention relates to a concrete floor forming member for forming a concrete floor such as an entrance, a bathroom, a deck, and a veranda in a residential building, and an L-shaped edge member used together with the concrete floor forming member.

When building a structure such as a wooden house, a concrete foundation is made on the outer shell and inner shell of the part where the building should be built, and a wooden base is fixed on the base and a pillar is placed on the wooden base. There is a method of placing a beam on a pillar. Such a technique is a traditional Japanese architecture technique and is widely used in the construction of wooden houses.

FIG. 10: is sectional drawing which shows the general construction method between entrance soil in the building for detached houses. 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.

Further, a base portion concrete 103 including a reinforcing bar (hereinafter referred to as a base portion) is formed thereon, and then a rising portion 104 (hereinafter referred to as a foundation concrete) formed on the base portion 103 is not illustrated. A mold is erected and fixed to the base portion 103.

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

Then, the general construction method of the floor part between entrance soils in the building for detached houses used as the object of the present invention is explained.
After the foundation portion construction process is completed, the backfill soil 105 is piled up to a predetermined height, and then the discarded concrete 106 is placed on the backfill soil 105. The discarded concrete 106 is kept as flat as possible.

Further, a mold frame (not shown) for forming concrete 107 (hereinafter referred to as interstitial concrete) for forming the entrance soil is erected on the discarded concrete 106 and fixed to the discarded concrete 106.

Thereafter, the ready-mixed concrete is poured into a formwork, and left for a few days to solidify, whereby the soil concrete 107 is formed. Thereafter, the formwork is removed, the mortar 108 for tiles is applied on the soil concrete 107, and the tiles 109 are arranged to form a concrete floor portion between the entrance soil and the like.

Here, concrete is made by mixing cement, sand and water into a fluidized form and pouring into a pre-assembled metal or wooden formwork and solidifying. In such a general construction method, Since a large amount of ready-mixed concrete containing a large amount of is used, it takes a long time to solidify, and there is a problem that it takes time and construction on the construction site and increases costs.

For such a problem, for example, Patent Document 1 has a peripheral wall portion having a predetermined height, the upper surface side of the peripheral wall portion is opened, and projects inward from the peripheral wall to the bottom side of the peripheral wall portion. After installing this earth retaining material using a lightweight earth retaining material such as polystyrene foam with an overhang part integrated, fill the annular peripheral wall of this earth retaining material, and then, the earth retaining material and the earth There is disclosed a method for constructing a concrete soil part, characterized in that concrete is placed so as to be embedded.

Further, for example, Patent Documents 2 and 3 disclose a method for constructing an entrance soil portion in which an outer peripheral foundation is formed using a precast concrete foundation manufactured in advance at a factory, and then concrete is placed. ing.

These methods can reduce the amount of concrete used at the construction site. However, as with conventional general construction methods, the moisture contained in the ready-mixed concrete is insufficiently discharged, so it is still difficult to solidify the concrete. It took a long time and was insufficient as an effect of shortening the construction period.

Also, for example, in Patent Document 4, an insecticidal sheet material that has been subjected to chemical treatment is disposed on a portion of the surface of the base material that is in contact with the side of the mortar that is struck on the foundation concrete and that does not contact the mortar. A method for constructing the interstitial space part, characterized in that it is installed, is disclosed.

In this method, it is possible to provide an insect repellent structure capable of exerting an insect repellent effect without impairing the adhesion between the base material and the mortar in the dirt portion of the building. However, even with this method, the moisture contained in the ready-mixed concrete is insufficiently discharged, and it takes a long time to solidify the concrete. In addition, the effect of the drug treatment is limited, and the effect cannot be maintained unless the drug treatment is performed regularly. The limited chemical effect is also shown by the fact that many of the causes of collapse of wooden buildings were due to significant deterioration of the lumber of their legs.

In addition, for example, Patent Document 5 discloses a method for constructing an interfacial soil portion in which a space between entrance soils is formed with a precast concrete panel produced in a factory, and tiles are attached to the precast concrete panels in advance at the factory to form a soil. ing.

In this method, since it is not necessary to place concrete at the construction site, the construction period is shortened. However, the precast concrete panel is only placed on the stepped portion of the foundation, and the precast concrete panel is precast. There was a problem that a gap was formed between the concrete panel and the stepped portion, and an intrusion path for white ants was formed. In addition, this panel cannot change the shape and area at the construction site, so it is not suitable for the entrance soil of non-uniform buildings, and can respond quickly to design changes at the construction site. There was a problem that could not.

The connecting member 50 is a member for extending the length of the column base portion by fitting it to the column base member 40. By simply fitting the connecting member 50 to one end of the column base member 40, the column Although the length of the leg member 40 can be slightly extended, the two column base members 40 are respectively inserted into the end portions of the cylindrical portion 51, and the end portions of the column base member 40 are brought into contact with the protruding portions 53. The length of the column base can be extended to about twice as long.

By using this connecting member 50, even if unevenness is formed in the base portion where the concrete floor forming member is installed, it can be installed without generating unevenness in the panel portion. Further, when forming the concrete floor, it is possible to easily increase the height from the base portion to the panel portion.

Although the method of fitting the connecting member 50 to the column base member 40 is not limited to the following method, for example, the column base member 40 is inserted into the end portion of the cylindrical portion 51 and the end portion of the column base member 40 is inserted. The column base member 40 can be fitted to the connection member 50 by contacting the protrusion 53 with the protrusion 53. Moreover, the column base member 40 and the connection member 50 can be more firmly connected by fitting the fitting projection 54 and the fitting groove 45 provided on the outer wall portion of the column base member 40.

The material of the connection member 50 of the present invention is not particularly limited, and the same material as the column base member 40 can be exemplified.

When a resin is used as the material of the connection member 50 of the present invention, the connection member 50 having the shape shown in FIG. 5 can be easily formed by injection molding. Moreover, since it can cut | disconnect to arbitrary dimensions in a construction site, the height of a concrete pillar can be changed easily. Therefore, it is desirable that the connection member 50 of the present invention is composed mainly of a resin.

In addition, the shape of the cylinder part 51 is not limited to a cylindrical shape, It is possible to set arbitrarily according to the shape of the column base part to fit, such as a regular polygonal column and a deformation | transformation polygonal column. It is desirable to have a shape that can maintain strength as a concrete pillar.
Although the length of the cylinder part 51 is not specifically limited, About 35-60 mm is desirable.

Moreover, when the connection member 50 is installed in a manner in contact with the base portion, the moisture contained in the concrete can be discharged by the notch 52. The width can be arbitrarily set, but is preferably about 5 to 15 mm.

The protruding portion 53 is formed with a constant width and a constant thickness along the inner peripheral shape of the cylindrical portion 51. The width of the protruding portion 53 may be determined within a range in which the fitting column base portion does not penetrate, but specifically, about 1 to 10 mm is desirable.
Further, the protrusion 53 does not have to be formed along the entire circumference of the inner peripheral shape of the cylindrical portion 51, and may be delimited by a notch.

The fitting projection 54 is formed with a constant width and a constant thickness along the inner peripheral shape of the cylindrical portion 51. The width of the fitting protrusion 54 is preferably about the same as or slightly larger than the depth of the fitting groove 45 to be fitted, and specifically about 0.5 to 3 mm.
In addition, the fitting protrusion 54 does not have to be formed along the entire circumference of the inner peripheral shape of the cylindrical portion 51, and may be separated by a notch.

FIG. 6A is a plan view schematically showing an L-shaped edge member provided on at least a part of the outer peripheral portion of the panel portion, and FIG. 6B is a right side view thereof.

The L-shaped edge member 60 is composed of two strip-like plate bodies 61a and 61b, and the plate-like body 61a and the plate-like body 61b are connected in a substantially L shape in cross section.

As will be described in detail later, the L-shaped edge member 60 is arranged such that one surface 61a is disposed on the panel portion 10 and the other surface 61b is in close contact with the foundation concrete 104 that borders the panel portion 10. Placed in. As a result, even if a gap is generated between the panel and the surrounding wall when it is placed, the gap can be filled with a small gap, and the flow of concrete can be prevented. In addition, it is possible to securely close the gap between the surrounding wall and the panel part by attaching it to the surrounding wall with a fixing tape such as double-sided tape, and it is placed on the foundation concrete etc. from the ground. The path for white ants to enter the base can be cut off, and ant damage can be prevented.
Moreover, if it installs in the part which does not have a wall in the circumference | surroundings, the wall of the height can be formed and the poured concrete can be received.

The material of the L-shaped rim material 60 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 resin is used as the material of the L-shaped edge member 60 of the present invention, the L-shaped edge member 60 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 member 60 of the present invention is composed mainly of a resin.

The length of each side of the L-shaped edge member 60 is not particularly limited, but it is desirable to have a height equal to or higher than the height of the soil concrete 3 to be placed. This is because the soil concrete 3 overflows from the L-shaped edge material 60.

The thickness of each side of the L-shaped edge member 60 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 edge member 60, but is generally preferably about 0.5 to 5 mm.

Next, a method for forming a concrete floor such as an entrance using these members will be described.
In the present invention, the method for forming the concrete floor is not particularly limited, but it is desirable to employ the following method.

FIG. 7 is a cross-sectional view schematically showing an example in which a concrete floor is formed on a solid foundation using the concrete floor forming member according to the present invention.

In the present invention, first, the base portion 103 and the foundation concrete 104 are formed by the construction method described in the background section. Since the construction method has been described in the section of the background art, a detailed description is omitted here.

Next, a concrete floor forming member assembling step is performed.
In other words, a concrete pouring through hole 21 is formed, and a plurality of fitting portions 20 having rising portions 22 provided around the concrete pouring through hole 21 and a plurality of drainage through holes 31 are provided. The column base member 40 (see FIG. 4) is fitted into the rising portion 22 of the panel member 10 (see FIGS. 1 to 3) to form the concrete floor forming member 1.

Normally, in the case of a solid foundation, the base portion 103 is flat, but when the base portion 103 has irregularities, the connection member 50 is further fitted to some of the plurality of column base portions fitted to the panel portion. Let In order to precisely match the unevenness of the base portion 103, the connecting member 50 and the column base may be cut to an appropriate length. At this time, if necessary, the connecting member 50 is connected to the lower end of the column base member 40 or the column base member 40 according to the height difference between the height position of the base portion 103 and the concrete floor formation height position. For example, the height position of the panel member 10 is adjusted.

Moreover, in order to match with the shape and dimensions of the front soil, a part of the concrete floor forming member 1 may be cut to adjust the shape. That is, for example, when the panel member 10 is 440 mm × 440 mm, and the shape and size of the entrance soil portion are half-finished in a state where the panel members 10 having the above dimensions are combined vertically and horizontally, the panel portion is cut. Thus, the concrete floor forming member 1 having a shape and a size matched to the shape and size of the interstitial space can be obtained.
When the panel member 10, the column base member 40, etc. are comprised with the resin material, it can cut | disconnect easily with common cutting tools, such as a cutter and a saw.

Further, as described above, when the fitting portion 20 is cut off by cutting the panel portion, the mounting state of the panel portion may become unstable as it is. Therefore, in this case, the panel portion is supported by fitting the column base member 40 to the rib 11 of the panel portion using the notch 44 of the column base member 40, and thus the concrete floor is formed. You may make it assemble a member. In this case, the part into which the column base member 40 is fitted is not particularly limited.

Next, a concrete floor forming member installation step is performed.
Here, it installs in the part between entrance soils (base part 103) with a column base part facing down so that the member 1 for concrete floor formation may be combined.
At this time, by arranging the panel member 10 so that the step portions 13 formed on the panel member 10 are overlapped, a large number of panel members 10 can be combined firmly and stably. Since the flat surface 11b exists below, when the concrete is formed on the top, the soil concrete 2 does not leak from the joint of the panel member 10 to the bottom.

After this step, in order to prevent contact between the soil concrete 2 and surrounding members (foundation concrete 104, etc.) due to the pouring of the soil concrete 2, on the outer peripheral upper portion of the installed concrete floor forming member 1, on the upper surface portion of the panel portion On the other hand, you may perform the L-shaped edge material attachment process which attaches the L-shaped edge material 60 which has the same plane, and has a plane perpendicular | vertical to an upper direction so that it may contact | adhere to the foundation concrete 104. FIG.

By attaching the L-shaped edge member 60 so as to be in close contact with the foundation concrete 104, the path for the white ants to enter the foundation placed on the foundation concrete from the ground can be cut off, and ant damage can be prevented. .

The number of the L-shaped edge members 60 and the length of the installation portion can be adjusted as necessary. However, providing the L-shaped edge members 60 so as to surround the entire circumference of the outer periphery is effective in preventing ants. It is desirable to increase
In order to bring the L-shaped rim material 60 into intimate contact with surrounding members such as the foundation concrete 104, a method of adhering a double-sided tape to a portion to be in close contact with the L-shaped rim material 60 or using an adhesive is employed. be able to.

Next, a concrete pouring process is performed.
That is, the ready-mixed concrete is poured into the panel portion of the concrete floor forming member 1 and the inside of the column base portion through the concrete pouring through hole 21.
At this time, a necessary amount of ready-mixed concrete is poured so that the thickness of the solid concrete 2 after solidification is about 30 to 100 mm.

Next, a concrete solidification step is performed in which the concrete formed on the panel portion and the concrete filled in the column base are solidified.

As described above, the moisture in the poured ready-mixed concrete is discharged from the drainage through hole 31 provided in the panel portion and is also discharged from the drainage hole 15. Further, inside the column base part, water is discharged also from the drain notch 42 of the column base part exposed under the rising part 22, and the drain notch 42 formed at the lower part of the column base part, Water is also discharged from the cutout 43 and the fitting cutout 44.

Accordingly, the ready-mixed concrete can be quickly solidified, and the soil concrete 2 can be obtained.

FIG. 8 is a cross-sectional view schematically showing an example in which a concrete floor is formed at the entrance using a cloth foundation using the concrete floor forming member according to the present invention.
In the case of the fabric foundation shown in FIG. 2, the cracked stone 101 and the discarded concrete 102 are provided with a predetermined width under the foundation concrete 104, and no concrete is provided in other portions. And in the case of a solid foundation, the backfill soil 105 is provided in the site | part where the concrete is cast.

In the method of forming the concrete floor at the entrance portion using the cloth foundation, the backfill soil is used instead of the base portion 103 as compared with the method of forming the concrete floor at the entrance portion using the solid foundation shown in FIG. Other than placing the concrete floor forming member 10 on 105, it is the same, so detailed explanation is omitted. However, when ready-mixed concrete is poured, it will be in the backfill soil 105 compared to the case of a solid foundation. Drying is relatively fast due to easy moisture penetration.

When the interstitial concrete 2 is formed on the backfilling soil 105, ants and the like easily reach the wooden base 112 through the backfilling soil 105, but in the present invention, the adhesive is used to closely contact the foundation concrete 104. By attaching the L-shaped edge member 60 in such a manner, the invasion path of white ants can be blocked and ant damage can be completely prevented.
Moreover, by attaching the L-shaped edge member 60, the moisture contained in the soil concrete 2 formed on the panel portion is prevented from being transmitted to the foundation concrete 104, and the moisture is diffused to the surrounding members ahead. Can block and prevent decay of wood.

FIG. 9 is a cross-sectional view schematically showing an example in which the panel member of the concrete floor forming member of the reference example is placed on the height adjusting member and the concrete floor is formed at the entrance portion using the solid foundation. is there.

In this method, in the concrete floor forming method described above, the height adjusting member arranging step is performed prior to the floor forming member assembling step.
That is, the height adjusting member 4 is arranged on the base portion 103 at an appropriate interval to form a column portion that supports the panel member 10. It is necessary to arrange the height adjusting members 4 so that the heights are equal. This is because a flat surface without inclination is formed when the panel member 10 is placed. It is desirable to arrange the height adjusting member 4 so as to exist below the through hole 21 for pouring concrete. This is because the concrete pillar is formed on the height adjusting member and integrated into the pillar.
In addition, as a height adjustment member, a concrete pillar, a boulder, soil, abandoned concrete, etc. can be used.

In addition, the column base portion 40 (see FIG. 4) is not inserted into the rising portion 22 of the panel member 10 (see FIGS. 1 to 3) in the floor forming member assembly process, and the panel member 10 is placed in the floor forming member installation process. Since it is the same as the concrete floor formation method mentioned above except mounting on the height adjustment member 4, detailed description is abbreviate | omitted.
