Description

  The present invention relates to a floor construction method for a building, and more particularly, to a floor construction method for laying a tatami mat on a floor foundation and laying tatami peripheral members such as flooring and parting material along the outer periphery of the tatami laying location.

Conventionally, a floor structure is known in which a tatami mat is laid on a floor foundation and tatami peripheral members such as flooring and parting materials are laid along the outer periphery of the tatami laying site (see, for example, Patent Document 1).
Further, in Patent Document 1, a tatami mat is laid on a floor base, and then a parting material as a first tatami peripheral member is fixed to the outer periphery of the tatami mat, and then a second mat is arranged on the outer periphery of the parting material. A construction method for installing a sound insulation flooring material as a peripheral member is described.

JP 2006-241704 A

However, in the construction method of fixing tatami peripheral members such as parting materials on the outer periphery after laying the tatami mat as described above, it is difficult to obtain sufficient contact between the tatami mats and the tatami peripheral member. In addition, the gap between the tatami mat and the parting material becomes large, and there is a possibility that the quality of the finished product is deteriorated. Further, when the gap becomes large in this way, an operation for adjusting the gap again becomes necessary, and the labor for construction increases. In particular, when standard tatami mats produced in large quantities at factories or the like are used as tatami mats, the tatami mats have finished dimensional errors, and it is difficult to adjust the dimensions at the construction site.
In contrast to the above construction method, in the method in which the parting material is first installed in a frame shape on the floor base, and then the tatami is laid, in addition to the above problem, the tatami fits in the frame formed by the parting material. There was also a risk of problems that could not be solved. In this case as well, construction labor such as adjustment of the position of the parting material is further increased.

  The present invention aims to solve the above-mentioned problems, and in a floor structure in which tatami peripheral members are installed on the outer periphery of a tatami laying place, management of gaps between tatami mats and between tatami mats and tatami peripheral members. The purpose is to provide a floor construction method for a building that can improve the quality and improve the finished quality, and has excellent workability.

In order to achieve the above object, the present invention provides:
A floor construction method for a building in which a plurality of tatami mats are laid on the floor floor of the building, and surrounding members of the tatami laying place for laying the plurality of tatami mats are installed, and tatami peripheral members are installed.
Surrounding the outer periphery of the tatami laying location, a temporary frame installation step of installing a temporary frame on the floor foundation,
Tatami temporary placing step of temporarily placing the tatami in the temporary frame;
Measure the size of the gap between the tatami mats temporarily placed and the gap between the tatami mat and the temporary frame, and from the size of the gap, the outer peripheral edge of the tatami laying position relative to the installation position of the temporary frame A gap measuring step for obtaining a correction value indicating the position;
The removal step of removing the temporarily placed tatami mat and the temporary frame from the floor base,
Based on the installation position of the temporary frame and the correction value, a tatami peripheral member installation step of installing a tatami peripheral member at a normal position of the outer periphery of the tatami laying location;
Tatami book installation step of permanently installing the tatami in the tatami laying location surrounded by the tatami peripheral members,
It was set as the floor construction method of the building characterized by having.

In the building floor construction method of the present invention,
In the gap measurement step, the difference between the vertical gap and the horizontal gap in the direction along the vertical and horizontal directions of the tatami mat and the reference value of each gap, the total value in the vertical and horizontal directions, respectively, It is preferable to set the correction values in the vertical direction and the horizontal direction, respectively.
Moreover, in the tatami mat temporary placing step, the tatami mat is temporarily placed from a position close to a reference corner portion which is a preset corner portion in the temporary frame,
In the tatami peripheral member installation step, the tatami peripheral members arranged on two sides surrounding the reference corner portion are arranged at the same position as the temporary frame and surround a diagonal corner portion which is a diagonal of the reference corner portion. It is preferable that the tatami peripheral members arranged on the remaining two sides are arranged so as to be shifted from the installation position of the temporary frame by the correction value.
In addition, the temporary frame installation step includes a step of installing on the floor foundation a scraping plate for adjusting the tatami upper surface height with respect to the floor foundation in the tatami laying location,
In the temporary frame installation step,
First, the temporary frame is arranged on two sides surrounding the reference corner portion,
Next, the scraping and pasting plate is placed against the temporary frame on the two sides,
Furthermore, on the remaining two sides surrounding the diagonal corner portion of the scraped plywood, the dimensions are adjusted so that the outer peripheral edge is arranged on the outer peripheral edge of the tatami laying place,
Then, the temporary frame to be arranged at the position of the remaining two sides is placed in contact with the outer peripheral edge of the remaining two sides of the scraping and bonding board,
In the tatami peripheral member installation process,
First, after adjusting the size or position so that the outer peripheral edge position of the remaining two sides of the scraping board is shifted by the correction value, the scraping board is fixed to the floor base,
Next, it is preferable that the tatami peripheral member is placed on the four circumferences surrounding the tatami laying place by bringing the tatami peripheral member into contact with the outer peripheral edge of the scraping and laminating board.

In the building floor construction method of the present invention, tatami mats are temporarily placed in a temporary frame that surrounds the outer periphery of the tatami laying location, and the dimensions of the gaps between the tatami mats and the tatami mat and surrounding tatami mat members are measured. Then, the correction value is obtained, and the tatami peripheral member is installed at the normal position based on the correction value, and then the tatami mat is installed inside the tatami peripheral member arranged at the normal position.
Therefore, the gap between the tatami mats and the tatami mat and the tatami peripheral member can be prevented from becoming larger than the set value as compared with the case where the parting material is installed after laying the tatami mats. In addition, since the tatami peripheral member can be arranged at the normal position, even if the tatami peripheral member is fixed first, the interval between the tatami peripheral members is narrowed so that the tatami cannot be inserted.
Therefore, the manageability of the gap between the tatami mats and between the tatami mats and the tatami peripheral members can be improved to improve the finished quality, and the workability is also excellent.

Further, in the gap measurement step, the difference between the vertical gap and the horizontal gap in the direction along the vertical and horizontal directions of the tatami mat and the reference value of each gap, the total value in the vertical and horizontal directions, respectively, With the correction values in the vertical and horizontal directions, the following effects can be obtained.
That is, although the position accuracy at the time of installation of the temporary frame may be low, an appropriate installation position of the tatami peripheral member can be easily and accurately obtained based on this. And with these correction values, it is possible to determine the normal interval between the tatami peripheral members arranged facing each other with the installation position of the temporary frame as a reference.

Further, in the tatami mat temporary placing step, the tatami mat is temporarily placed from a position close to a reference corner portion that is a preset corner portion in the temporary frame, and in the tatami peripheral member installing step, two sides surrounding the reference corner portion are placed. The tatami peripheral member to be arranged is arranged at the same position as the temporary frame, and the tatami peripheral member to be arranged on the remaining two sides surrounding the diagonal corner portion that is a diagonal of the reference corner portion is disposed on the temporary frame. The following effects can be obtained with the arrangement shifted from the installation position by the correction value.
In other words, among the tatami peripheral members surrounding the four laps of the tatami laying location, only the ones arranged on the two sides need to be adjusted in position, so compared to adjusting the positions of all the tatami peripheral members on the four laps, Excellent workability.

In addition, the temporary frame installation step includes a step of installing on the floor foundation a scraping plate for adjusting the tatami mat upper surface height with respect to the floor foundation at the tatami laying location. In the temporary frame installation step, First, the temporary frame is disposed on two sides surrounding the reference corner portion, and then the scraping plate is disposed so as to abut against the temporary frame on the two sides, and further, the pair of the scraping plates On the remaining two sides surrounding the corner portion, the size adjustment is performed so that the outer peripheral edge is arranged on the outer peripheral edge of the tatami laying place, and then the temporary frame arranged at the position of the remaining two sides In the tatami peripheral member installation step, first, the outer peripheral edge positions of the remaining two sides of the scraping plate are the corrections. Dimension adjustment or position to be shifted by the value After adjusting, when the flooring board is fixed to the floor base, and then the tatami peripheral member is brought into contact with the outer peripheral edge of the flooring board, and installed around the tatami laying place, the following, The effect of can be obtained.
In other words, when installing the tatami peripheral member, the tatami peripheral member can be installed at the normal position simply by contacting the outer peripheral edge of the littering board, and the position relative to the floor base is measured and adjusted. However, the installation work is unnecessary and the workability is excellent.
In addition, in order to obtain such good workability, a scraping board that adjusts the surface height of the tatami mat with respect to the floor base is used, so a member for adjusting the position of the tatami peripheral member is set separately. This is advantageous in terms of cost.

As the upper cushion material 22 and the lower cushion material 24, for example, synthetic resin foams such as non-crosslinked polyolefin, crosslinked polyolefin, polyurethane, polystyrene, and elastomer can be used. Further, the level difference adjusting member 24 a is a synthetic resin sheet including fibers having the same thickness as the tatami mat 23.
As the tatami table 23, any tatami table conventionally used as a tatami mat table (for example, a tatami table manufactured from grass, polyolefin resin, Japanese paper, etc.) can be used.

(Floor construction method)
Next, the floor construction method according to the embodiment will be described in order based on the drawings.
<Inking process>
The ink marking process is a process of performing ink marking for installing a temporary frame 40 to be described later at a position surrounding the four circumferences of the tatami laying place 200 that is a place where the tatami 20 of the room RM is laid.
That is, as shown in FIG. 2, the dimensions a, b, c for installing the flooring material 10 and the parting material 30 from the inner periphery of the room RM to the surface of the floor base 50 exposed to the room RM at this time. , D are drawn at positions separated by d, LX1, LX2, LY1, LY2.

<Temporary frame installation process>
The temporary frame installation step is a step of installing the temporary frame 40 on the surface of the floor foundation 50.
The temporary frame 40 is a frame in which the four elongated wooden crosspieces 41, 42, 43, and 44 shown in FIG. 5 are installed in a square frame shape along the outside of the inking lines LX1, LX2, LY1, and LY2. As shown in FIG. 3, two wooden crosspieces 41 and 42 are temporarily fixed at positions on two sides surrounding a reference corner portion 40 c that is one corner portion of a square frame formed by the temporary frame 40.
In this embodiment, the screw 45 is used for the temporary fixing, but the means is not limited to this, and other fixing tools such as a nail or an adhesive can be used.

Next, the littering board 60 is installed in the middle of this temporary frame installation process.
This discarding and bonding board 60 is installed on the floor foundation 50 as shown in FIG. In the present embodiment, five sheets of plywood 61 to 65 are installed as the discarded plywood 60.
In the installation of the littering board 60, first, as shown in FIG. 4, it is disposed on the side close to the reference corner portion 40c formed by the wooden crosspiece 41 and the wooden crosspiece 42, and the whole is within the range of the tatami laying place 200. The two plywoods 61 and 62 to be accommodated are fixed to the floor base 50 by using a fixture 66 such as a finish nail in a state where the edge portions thereof are in contact with the wooden crosspieces 41 and 42.
Further, the three plywoods 63, 64, 65 that cannot be entirely accommodated within the tatami laying place 200 are cut at positions that overlap the inking lines LX2, LY2, and the outer peripheral edges thereof are fixed first. Temporarily placed on the floor substrate 50 in contact with the plywood 61 and 62. In FIG. 4, the hatched portions of the plywoods 63 to 65 indicate the portions to be cut and cut off, and the non-hatched portions are temporarily placed on the floor base 50.

After that, as shown in FIG. 5, the wooden bars 43 and 44 are placed along the inking lines LX <b> 2 and LY <b> 2 and are brought into contact with the outer edges of the plywoods 63 to 64 to be temporarily fixed to the floor base 50.
Thus, the temporary frame installation process is completed.

<Tatami temporary storage process>
The tatami mat temporary placing process is a process of temporarily placing the tatami mat 20 on the tatami laying place 200 set inside the temporary frame 40.
In this tatami mat temporary placing step, the nine tatami mats 20 are disposed in order, while being pressed from the position close to the reference corner portion 40c toward the upper right direction in the drawing as shown by arrows, as shown in FIG. Temporarily place on top.
At this time, the gaps 201 (see FIG. 7) formed between the tatami 20 and the tatami 20 are arranged in a straight line in both the vertical and horizontal directions along the outer peripheral edge of the tatami laying place 200. It is preferable to adjust by changing the arrangement of the twenty.

<Gap measurement process>
The gap measuring step is a step of measuring the dimension of the gap 201 formed between the tatami mats 20 that have been temporarily placed and between the tatami mat 20 and the temporary frame 40.

  These gaps 201 are measured using a measuring tool such as a metal scale 100 as shown in FIG. Here, as shown in FIGS. 6 and 7, the left-right direction is x (this direction is hereinafter referred to as a horizontal direction) and the dimensions of the gaps 201 are Sx1 to Sx4, respectively. In both figures, the front-rear direction is y (this direction is hereinafter referred to as the vertical direction), and the dimensions of the gaps 201 are Sy1 to Sy4.

Then, when the measurement of the dimensions Sx1, Sx2, Sx3, Sx4, Sy1, Sy2, Sy3, Sy4 of each gap 201 is completed, next, correction values Kx, Ky are obtained.
These correction values Kx and Ky each have a horizontal correction value Kx and a vertical correction value Ky. These values are obtained by adding the numerical values obtained by subtracting the reference value Sa from the dimensions of the gaps 201, respectively. The correction values Kx and Ky are obtained. The reference value Sa is a target gap size.
Kx = (Sx1-Sa) + (Sx2-Sa) + (Sx3-Sa) + (Sx4-Sa)
Ky = (Sy1-Sa) + (Sy2-Sa) + (Sy3-Sa) + (Sy4-Sa)
The tatami mat 20 is generally laid so as to be in close contact with each other, and the reference value Sa is set to a small dimension of less than 1 mm.

  Therefore, when the correction values Kx and Ky are positive, it means that the current total gap is too large by the correction values Kx and Ky at the current temporary frame 40 position. That is, it means that the interval between the temporary frames 40 is too large by the correction values Kx and Ky. On the other hand, when the correction values Kx and Ky are negative, it means that the current gap is insufficient at the current temporary frame 40 by the correction values Kx and Ky. That is, the interval between the temporary frames 40 is insufficient by the correction values Kx and Ky.

<Tatami removal process (removal process)>
The tatami removal process is a process of removing all the tatami mats 20 temporarily placed on the tatami laying place 200 from the lump-bonding board 60.

<Temporary frame removal process (removal process)>
The temporary frame removing step is a step of removing all the temporary frames 40 installed on the floor base 50 from the floor base 50.

<Discarded plywood readjustment process>
In the present embodiment, after the temporary frame removing step, the scraping and pasting board readjustment step is carried out. ˜65 is a step of readjusting the size or the installation position according to the correction values Kx, Ky.

In this step, when the lateral correction value Kx is positive, the lateral dimensions of the plywood 63 and the plywood 65 are cut by the correction value Kx (the portion indicated by the slanted line in FIG. 8), and then the original position again. And fixed to the floor base 50 using a fixture 66 (see FIG. 4).
On the other hand, when the lateral correction value Kx is negative, after the plywood 63 and the plywood 65 are arranged away from the plywood 62 in the left direction in FIG. 8 by the correction value Kx from the temporarily placed position. The fixing tool 66 (see FIG. 4) is used for fixing.

If the correction value Ky in the vertical direction is positive, the vertical dimension of the plywood 64 and the plywood 65 is cut by the correction value Ky (the portion indicated by the slanted line in FIG. 8) and then placed again at the original position. And it fixes to the floor base 50 using the fixing tool 66 (refer FIG. 4).
On the other hand, when the correction value Ky is negative, after the plywood 64 and the plywood 65 are arranged apart from the plywood 61 to 63 in the vertical direction in the drawing by the correction value Ky from the temporarily placed position. The fixing tool 66 (see FIG. 4) is used for fixing.

<Parting material installation process (Tatami peripheral member installation process)>
The parting material installation process is a process of installing the parting material 30 as a tatami peripheral member by shifting the parting material 30 by an amount corresponding to the correction values Kx and Ky with respect to the installation position of the temporary frame 40.

  In this case, in the present embodiment, the parting materials 30 (a) and 30 (b) arranged on the two sides surrounding the reference corner portion 40c are installed at the same position as the wooden rails 41 and 42 of the temporary frame 40. On the other hand, the parting materials 30 (c), 30 (d) on the two sides surrounding the reference corner portion 40c and the diagonal corner portion 40d diagonal to the reference corner portion 40c are located with respect to the installation positions of the wooden crosspieces 43, 44 constituting the temporary frame 40. The positions are shifted to positions corresponding to the correction values Kx and Ky.

In the present embodiment, at this time, the positions of the outer edges of the plywoods 63 to 65 of the scraped plywood 60 are already shifted from the installation position of the temporary frame 40 by the amount corresponding to the correction values Kx and Ky. . For this reason, when arranging the parting material 30 in said position, in this Embodiment, each parting material 30 (a) (b) (c) (d) is a rounding board as shown in FIG. It only needs to be installed around the outer periphery of 60 in four rounds. Then, in this state, the fixing tool is hit from the side of the parting material 30 and fixed to the side surface of the discarding laminate 60, or the fixing tool is hit from above the parting material 30 and fixed to the floor base 50.
As shown in FIG. 10, the parting material 30 is a rectangular parallelepiped-like member, and when installed on the floor base 50, the upper surface of the parting material 30 is installed on the littering board 60. It is formed in the dimension arrange | positioned in the upper surface of 20 and substantially the same height.

<Flooring material installation process (Tatami peripheral member installation process)>
As shown in FIGS. 10 and 11, the flooring material installation step is a step of installing the flooring material 10 as a tatami peripheral member along the outside of the parting material 30.

As shown in FIG. 10, the flooring material 10 is placed on the floor substrate 50 so as to overlap the second scraping and bonding board 70. In addition, the thickness of the 2nd discarding board 70 is set so that the upper surface of the flooring material 10 may become substantially the same height as the upper surface of the tatami 20 at the time of installation of the flooring material 10.
Moreover, lamination | stacking with the flooring material 10 and the 2nd discarding board 70 may be previously performed at the factory etc., and may be performed at a construction site.

<Tatami book installation process>
The tatami mat installation process is a process of installing the tatami 20 on the littering board 60 in the tatami laying place 200 surrounded by the parting material 30.
In this case, the tatami 20 is disposed at the same position as when the tatami 20 is temporarily placed on the tatami laying place 200 in the tatami temporary placing process and the gap measuring process.

Moreover, the parting material 30 is arrange | positioned so that the dimension of the clearance gap 201 between the tatami 20 and between the tatami 20 and the parting material 30 may become the reference value Sa when the tatami 20 is laid. For this reason, the gaps 201 between the tatami mats 20 and between the tatami mat 20 and the parting material 30 can be set to a constant size, and high finished quality can be obtained while using standard tatami mats as the tatami mats 20. Moreover, the problem that the size of the tatami laying place 200 is insufficient and the tatami 20 cannot be accommodated does not occur.
Therefore, in this tatami mat installation process, it is not necessary to perform the work of replacing the tatami 20, the work of replacing the parting material 30, the size adjusting work, etc., and the workability is excellent.

As described above, in the building floor construction method of the present embodiment, the effects listed below can be obtained.
1) In this embodiment,
A temporary frame installation step of installing the temporary frame 40 so as to surround the outer periphery of the tatami laying place 200;
A tatami mat temporary placing step of temporarily placing the tatami mat 20 in the temporary frame 40;
The dimensions of the gap between the temporarily placed tatami mats 20 and the gap between the tatami mat 20 and the temporary frame 40 are measured, and from the dimensions of these gaps, the outer peripheral edge of the tatami laying place 200 with respect to the installation position of the temporary frame 40 is measured. A gap measuring step for obtaining correction values Kx and Ky indicating normal positions;
The tatami mat 20 and the temporary frame 40 that have been temporarily placed, the tatami mat removing step and the temporary frame removing step for removing from the floor base 50, and
A parting material installation process for installing a parting material 30 as a tatami peripheral member at a position surrounding the tatami laying place 200 based on the installation position of the temporary frame 40 and the correction values Kx, Ky (tatami peripheral member installation process). When,
A tatami book installation process in which a tatami 20 is installed in a tatami laying location 200 surrounded by the parting material 30;
The floor construction method of the building equipped with.
In this floor construction method, the tatami 20 is temporarily placed, and the correction values Kx and Ky are obtained based on the dimensions Sx1 to 4 and Sy1 to 4 of the gap 201, and the parting material is obtained based on the correction values Kx and Ky. 30 installation positions are determined.
Therefore, compared with the case where the parting material 30 is installed after laying the tatami 20, the gaps 201 between the tatami 20 and the tatami 20 and the parting material 30 can be prevented from becoming larger than the reference value Sa. Moreover, since the parting material 30 can be arrange | positioned in a regular position, even if it fixes the parting material 30 before the main laying of the tatami mat 20, the space | interval of the parting material 30 becomes narrow and the malfunction which cannot lay the tatami 20 may arise. Absent.
Therefore, even if standard tatami mats are used as the tatami mats 20, the gaps between the tatami mats 20 and between the tatami mats 20 and the parting material 30 are appropriate values, and high finished quality can be obtained. In this case, it is not necessary to perform the replacement work of the tatami 20, the replacement work of the parting material 30, the dimension adjustment work, and the like, and the workability is excellent.

2) In the embodiment, in the gap measuring step, the difference between the vertical gap and the horizontal gap dimensions Sy and Sx, which are intervals in the vertical and horizontal directions of the tatami mat 20, and the reference value Sa of each gap 201, respectively. The total value in the direction and the horizontal direction is set as the correction values Ky and Kx in the vertical direction and the horizontal direction, respectively.
Thus, since the correction values Kx and Ky are determined from the difference between the total value of the gap 201 and the reference value Sa in the vertical direction and the horizontal direction, respectively, the normal installation position of the parting material 30 as the tatami peripheral member is determined. It can be easily obtained. Based on these correction values Kx and Ky, the regular interval between the pair of facing parting materials 30 (a) and 30 (d) and the parting material 30 (b) and 30 (c) is used as a reference for the installation position of the temporary frame 40. Can be requested.
Moreover, although the position accuracy at the time of installation of the temporary frame 40 may be low, the proper installation position of the parting material 30 corresponding to the standard tatami 20 having a dimensional error is accurately grasped based on this. Can do.

3) In the tatami mat temporary placing step, the tatami mat 20 is temporarily placed from a position close to the reference corner portion 40c which is a preset corner portion in the temporary frame 40,
In the tatami peripheral member installation process, the parting materials 30 (a) and 30 (b) arranged on the two sides surrounding the reference corner portion 40c are arranged at the same position as the wooden crosspieces 41 and 42 of the temporary frame 40, and the diagonal corner. The parting materials 30 (c) and 30 (d) arranged on the remaining two sides surrounding the portion 40 d are arranged so as to be shifted by correction values Kx and Ky with respect to the installation positions of the wooden frames 43 and 44 of the temporary frame 40. I tried to do it.
For this reason, only the two parting materials 30 (c) (d) out of the four parting materials 30 (a) to (d) need to be adjusted, so that the four parting materials 30 (a ) To (d) are excellent in workability as compared with adjusting all positions.

4) The temporary frame installation process includes a process of installing the lump-bonding board 60 on the floor foundation 50 in the tatami laying place 200,
In the temporary frame installation process,
First, the wooden frames 41 and 42 of the temporary frame 40 are arranged on two sides surrounding the reference corner portion 40c,
Next, the plywoods 61 and 62 of the littering plywood 60 are placed against the wooden crosspieces 41 and 42 of the temporary frames 40 on the two sides,
Furthermore, on the remaining two sides surrounding the diagonal corner portion 40d of the scraping and pasting board 60, dimensional adjustment is performed so that the outer peripheral edge is arranged on the outer peripheral edge of the tatami laying place 200,
After that, the temporary frame 40 (wood bars 43, 44) to be arranged at the remaining two sides is placed in contact with the outer peripheral edges of the remaining two sides of the scraping plate 60,
In the tatami peripheral member installation process,
First, after adjusting the size or adjusting the position so that the outer peripheral edge positions of the two corners surrounding the diagonal corner portion 40d of the scraping plate 60 are shifted by the correction values Kx and Ky, the scraping plate 60 is moved under the floor. Fixed to the ground 50,
Next, the parting material 30 was put in contact with the outer peripheral edge of the scraping and pasting board 60 and installed around the tatami laying place 200.
In this way, the parting material 30 can be installed at a normal position based on the correction values Kx and Ky only by being brought into contact with the outer peripheral edge of the scraping board 60, and the position relative to the floor substrate 50 can be determined. The installation work while measuring and adjusting is unnecessary and the workability is excellent.
In addition, in order to obtain such good workability, a scraping board 60 that adjusts the surface height of the tatami 20 with respect to the floor base 50 is used, so a member for adjusting the position of the parting material 30 is separately provided. Compared with setting, it is advantageous in terms of cost.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to such embodiment, In the range which does not deviate from the summary of this invention, a various deformation | transformation and substitution can be added.

For example, a room for laying a tatami is not limited to a room having the shape and size shown in the embodiment. In short, the floor construction method of the present invention can be applied if a tatami is installed on a frame-like tatami laying site surrounded by tatami peripheral members on the floor foundation.
In the embodiment, the semi-tatami mat type is shown as the tatami mat, but the tatami mat is not limited to this, and a tatami mat type may be used.

  Moreover, as a tatami peripheral member, it is not limited to the parting material and flooring material which were shown in embodiment, for example, the flooring material and scraping board shown by embodiment were used as a tatami peripheral member, and in embodiment You may make it lay a tatami | tatami on the inner periphery of these flooring materials and a littering board, without interposing the shown parting material.
