Abstract

PROBLEM TO BE SOLVED: To improve a technique related to a wooden floor panel for a house and a floor structure using the wooden floor panel, and to reduce a material volume without impairing the rigidity of the floor panel.
SOLUTION: A basic dimension L is set (455 mm in this example), three long joists 1a, 1b, and 1c having a width dimension w and a length dimension 4L are arranged in parallel, and a length dimension L-1.5w is set. Six short joists 2a, 2b-2 are arranged in a direction perpendicular to the long joists to form a rice field structure 9 composed of four frames 7, and both ends of the floor panel P in the longitudinal direction. Two U-shaped structures 8 are formed in each part. Since the U-shaped structure 8 has one shorter joist than the frame 7, the material volume is reduced accordingly. However, since the opening portion of the U-shaped structure is fixed to the horizontal member 5, there is no possibility of causing a decrease in strength (particularly, lack of rigidity) due to the omission of short roots.

It is highly appreciated that the well-known invention of Patent Document 1 makes the flooring of a house easier and increases the rigidity of the floor structure.
An object of the present invention is to provide a floor panel technology having a novel configuration that can reduce the volume of a wooden floor panel without impairing the advantages (easy construction and high rigidity) of the above-described known invention. .
The cost can be reduced by reducing the volume, and the social demand for saving resources can be met. In particular, by saving wood, it is expected to contribute to the whole human problem of “protecting greenery and preventing global warming”.

The configuration of the invention according to claim 1 (see FIG. 1) is a wooden floor panel (Pa) for building a house.
Assuming Cartesian coordinates XY consisting of a horizontal X-axis and a horizontal Y-axis, the side length dimension L of the basic frame is set,
Three long joists (1a, 1b, 1c) having a length dimension 4L and a width dimension w are arranged in the Y-axis direction with a spacing dimension L-1.5w,
Six short joists (2a, 2b, ˜2f) having a length dimension L-1.5w are arranged in the X-axis direction across the three long joists,
The three long joists and the six short joists constitute the frame of the floor panel (Pa),
Four square frames (7) having a side dimension of about L are formed at the center of the frame, and the four frames are adjacent to each other to form a rice-shaped structure (9).
In addition, a U-shaped structure (8) having a side dimension of about L is formed at each of both ends in the longitudinal direction (Y-axis direction) of the floor panel.

According to the device of the first aspect described above, the material volume can be reduced without impairing the rigidity as compared with the floor panel according to the prior art.
That is, while ensuring sufficient rigidity by the rice field-shaped structure in the center,
With the U-shaped structure at both ends, it was obtained that the joist on one side corresponding to the U-shaped opening was omitted without impairing the rigidity.
The U-shaped opening is a structural part that can be attached to the horizontal member, and this horizontal member is much stronger than the joist member, so it is rigid even if the joist member in contact with it is omitted. There is no possibility of causing a shortage (large deflection).
Not only does it reduce production costs by reducing volume, it also greatly contributes to the conservation of forest resources by reducing wood consumption.

The structure of the device according to claim 2 (see FIG. 4B) is a wooden floor panel (Pb) for building a house.
Assuming Cartesian coordinates XY consisting of a horizontal X-axis and a horizontal Y-axis, set the side length dimension L of the basic frame,
Three long joists (1d, 1e, 1f) having a length dimension 3L and a width dimension w are arranged with a spacing dimension L-1.5w in the Y-axis direction,
Four short joists (2) having a length dimension L-1.5w are arranged in the X-axis direction, spanning between the three long joists.
The three long joists and the four short joists form the framework of the floor panel (Pb),
Two “substantially square frames with a side length of about L” are formed in the center of the framework, and the two frames are adjacent to each other to form a “Japanese character-shaped structure”.
In addition, a total of four “two U-shaped structures each having a side length of about L” are formed at both ends in the longitudinal direction (Y-axis direction) of the floor panel. And

According to the invention of claim 2 described above, as in the case of claim 1, the material volume can be reduced without impairing the rigidity of the floor panel.
As in claim 1, not only the production cost is reduced by the reduction of the volume, but also the consumption of wood and the conservation of forest resources are reduced.

The configuration of the invention according to claim 3 (see FIG. 4 (C)) is a wooden floor panel (Pc) for building a house.
Assuming Cartesian coordinates XY consisting of a horizontal X-axis and a horizontal Y-axis, the side length dimension L of the basic frame is set,
Three long joists (1g, 1h, 1i) having a length dimension 2L and a width dimension w are arranged with a spacing dimension L-1.5w in the Y-axis direction,
Two short joists (2) having a length L-1.5w are arranged in a straight line in the X-axis direction, spanning between the three long joists.
The three long joists and the two short joists constitute the framework of the floor panel (Pc),
A total of four “U-shaped structures each having a side length of about L” are formed in each of both ends of the floor panel frame in the Y-axis direction.

The floor panel according to the invention of claim 3 described above has an area about half that of the floor panel of claim 1. For this reason, it is very convenient to cover the small area which was not covered when the floor panel of Claim 1 was arranged with the floor panel of this Claim 3. In this way, when used as an aid to the floor panel of claim 1, the floor stiffness distribution is made uniform by the cooperation of both types of floor panels.
In addition, the floor panel itself of claim 3 has a material saving effect which is superior to claim 1.

  In addition to the structural requirements of the floor panel according to the first to third aspects of the invention, the configuration of the fourth aspect of the invention (see FIG. 3) is about at least one of the three long joists. A backing plate (3) is mounted on the lower surface of the sail direction so as to protrude laterally from the lower surface of the long joist, reducing the bending deformation of the long joist and making a rectangular plate-like heat insulating plate (4) is supported.

According to the invention described in claim 4 described above, the side edge of the backing plate projects laterally from the lower surface of the long joist. This overhanging portion also serves to support the weight of the rectangular heat insulating plate.
Furthermore, since the backing plate is attached to the lower surface of the long joist, the rigidity of the long joist increases and the bending due to the load (weight of a person, furniture, etc.) is completely prevented in practice.
In the floor panel according to the present invention, since the long joists are attached to the horizontal member to support the load, the high rigidity of the long joists is important.
From such a viewpoint, the backing plate is attached to the lower surface of the long joist.
However, this does not prevent the backing plate from being attached to the bottom surface of the short joists as required.

  In addition to the constituent features of the inventions of the first to fourth aspects (see FIG. 3B), the configuration of the device according to the fifth aspect has side length dimensions of L-1.5w and L-w. The plate-like heat insulating plate (4, 4 ') is formed, and these plate-like heat insulating plates are fitted into the frame (7) and / or the U-shaped structure (8). And

According to the device of the fifth aspect described above, the rectangular heat insulating plate is fitted into the floor panel. If this work is carried out at the floor panel manufacturing factory, the heat insulation construction at the building construction site is remarkably facilitated, the quality of the heat insulation is ensured, and the number of heat insulation construction work at the site is reduced.
In addition, it is easy to transport, store, and manage materials related to insulation, and there is no risk of mistakes in work due to human error. In this way, a floor structure excellent in heat insulation and heat retention is supplied at low cost.
Moreover, the square insulation board is only fitted into the frame of the floor panel or the U-shaped structure, so the square insulation board can be temporarily removed or reattached as necessary depending on the circumstances of the floor construction. It is very convenient.

The configuration of the invention according to claim 6 (see FIG. 3B) is that the thickness dimension t of the rectangular plate-like heat insulating plate is smaller than the vertical dimension H of the long joists and short joists,
An air gap is formed between the face material (not shown in FIG. 3B) installed so as to cover the long and short joists and the heat insulating plate (4, 4 ').

  According to the device of the sixth aspect described above, since the air gap is blocked between the heat insulating material and the face material, the heat insulating effect can be further improved with little cost. it can.

The configuration of the device according to claim 7 is in addition to the structural requirements of the floor panel according to the devices of claims 1 to 5 (see FIG. 5).
At least one type of floor panel according to claim 1;
A horizontal frame in which a plurality of horizontal members (5) are installed with an interval dimension of about 2 nL (where n is an integer of 1 or more) or an interval dimension mL (where m is an integer of 2 or more, preferably 3 or 4). It consists of a combination of material structures.

Applying the device of claim 7 described above, the length dimension (Y-axis direction dimension) is 4L, and the floor panel of claim 1 or the length dimension (Y-axis direction dimension) is 3L. The floor panel of FIG. 4 and the dimension in the Y-axis direction are 2L, and the “open ends of the U-shaped structure portion” formed at both ends of the floor panel of claim 3 are reasonably arranged in contact with the horizontal member can do.
The U-shaped portion attached (fitted) in contact with the horizontal member forms a frame by combining with the horizontal member, and exhibits rigidity. In this way, the material volume is reduced without reducing the strength (the U-shaped structure has a smaller material volume than the frame structure).
If the floor panel of any one of claims 1 to 3 is used according to the construction design, it corresponds to the device of the present invention. However, this does not prevent the use of two or three types of floor panels. That is, no matter how many kinds of floor panels are used, they belong to the technical scope of the present invention.

  In the configuration of the invention according to claim 8, in addition to the configuration requirements of the invention of claim 7, (see FIG. 6), there are a plurality of one face material on the floor panel arranged across the horizontal member. It is characterized by being mounted across the floor panel.

  According to the invention described in claim 8 described above, out of the many floor panels arranged horizontally, the two floor panels adjacent to each other are free from unevenness and the flatness of the floor surface is improved. Moreover, the mechanical strength is increased.

  The configuration of the invention according to claim 9 is based on the long and short joists of the floor panel forming the floor structure in addition to the configuration requirements of the inventions of claims 1 to 3 (see FIG. 5B). Further, the movable partition (6) is installed in the upper side without necessarily being positioned directly above the horizontal member or joist.

  According to the invention of claim 9 described above, the floor panel according to claims 1 to 3 of the present invention has high rigidity, and in particular, the fact that the rigidity distribution is uniform over the entire floor surface makes it possible to use any location. A movable partition can be installed on the door, and a customer-oriented interior can be easily achieved. In addition, it is easy to move the partition of existing houses.

According to the first aspect of the present invention, the material volume can be reduced without impairing the rigidity as compared with the floor panel according to the prior art.
That is, while ensuring sufficient rigidity by the rice field-shaped structure in the center,
With the U-shaped structure at both ends, it was obtained that the joist on one side corresponding to the U-shaped opening was omitted without impairing the rigidity.
The U-shaped opening is a structural part that can be attached to the horizontal member, and this horizontal member is much stronger than the joist member, so it is rigid even if the joist member in contact with it is omitted. There is no fear of causing a shortage of (large deflection).
Not only does it reduce production costs by reducing volume, it also greatly contributes to the conservation of forest resources by reducing wood consumption.

According to the invention of claim 2, as in the case of claim 1, the material volume can be saved without impairing the rigidity of the floor panel.
As in claim 1, not only the production cost is reduced by the reduction of the volume, but also the consumption of wood and the conservation of forest resources are reduced.

The floor panel according to the invention of claim 3 is about half the area of the floor panel of claim 1. For this reason, it is very convenient to cover the small area which was not covered when the floor panel of Claim 1 was arranged with the floor panel of this Claim 3. In this way, when used as an aid to the floor panel of claim 1, the floor stiffness distribution is made uniform by the cooperation of both types of floor panels.
In addition, the floor panel itself of claim 3 has a material saving effect equal to or greater than that of claim 1.

According to the invention of claim 4, the side edge of the backing plate protrudes laterally from the lower surface of the long joist. This overhanging portion also serves to support the weight of the rectangular heat insulating plate.
Furthermore, since the backing plate is attached to the lower surface of the long joist, the rigidity of the long joist increases and the bending due to the load (weight of a person, furniture, etc.) is completely prevented in practice.
In the floor panel according to the present invention, since the long joists are attached to the horizontal member to support the load, the high rigidity of the long joists is important.
From such a viewpoint, the backing plate is attached to the lower surface of the long joist.

According to the invention of claim 5, the rectangular heat insulating plate is fitted into the floor panel. If this work is carried out at the floor panel manufacturing factory, the heat insulation construction at the building construction site is remarkably facilitated, the quality of the heat insulation is ensured, and the number of heat insulation construction work at the site is reduced.
In addition, it is easy to transport, store, and manage materials related to insulation, and there is no risk of mistakes in work due to human error. In this way, a floor structure excellent in heat insulation and heat retention is supplied at low cost.
Moreover, the square insulation board is only fitted into the frame of the floor panel or the U-shaped structure, so the square insulation board can be temporarily removed or reattached as necessary depending on the circumstances of the floor construction. It is very convenient.

  According to the sixth aspect of the present invention, a gap is formed between the heat insulating material and the face material so that the air flow is blocked. As a result, the heat insulation effect can be further improved with little cost.

When the invention of claim 7 is applied, the floor panel of claim 1 whose length dimension (Y-axis direction dimension) is 4L, or the floor panel of claim 2 whose length dimension (Y-axis direction dimension) is 3L. The dimension in the Y-axis direction is 2L, and the "open ends of the U-shaped structure portion" formed at both ends of the floor panel according to claim 3 can be rationally arranged in contact with the horizontal member. .
The U-shaped portion attached (fitted) in contact with the horizontal member forms a frame by combining with the horizontal member, and exhibits rigidity. In this way, the material volume is reduced without reducing the strength (the U-shaped structure has a smaller material volume than the frame structure).

  According to the invention of claim 8, among the many floor panels arranged horizontally, the two floor panels adjacent to each other are free from unevenness, and the flatness of the floor surface is improved. Strength increases.

  According to the invention of claim 9, by utilizing the fact that the floor panel according to claims 1 to 3 of the present invention has high rigidity, in particular, the rigidity distribution is uniform over the entire floor surface, movable partitions are provided at arbitrary locations. It can be installed and a customer-oriented interior is easily possible. In addition, it is easy to move the partition of existing houses.

FIG. 1 shows a framework of an A-shaped floor panel (Pa) according to an embodiment of the present invention, and the opening ends of U-shaped structures formed at both ends in the longitudinal direction are arranged between horizontal members 5. It is the figure which added horizontal coordinate XY to the top view which drawn the place spanned to.
A dimension L of one side of the basic frame constituting the skeleton is set. Although this dimension L can be determined arbitrarily, it is set to 455 mm in the present embodiment because of the relationship with the standards of houses and joinery.
Three long joists 1a, 1b, and 1c are arranged in the Y-axis direction with a spacing dimension L.
However, the distance between the center lines is L, and the inner method (inner weight) dimension is L-1.5w (w is the width dimension of the long joist).

Reference numerals 2a, 2b to 2f are attached to indicate six short joists having a length dimension L-1.5w.
Although the width dimension of the short joist can be arbitrarily set, in the present embodiment, w is set to be the same as the width dimension of the long joist.
When attention is paid to the left half or the right half of the floor panel shown in FIG. 1, each has a three-stage ladder shape. Thus, the present invention is characterized in that it is a “composite ladder-type floor panel” in which two ladders are combined.
That is, there is no joist in the X-axis direction at both ends in the Y-axis direction, and “a U-shaped structure 8 opening in the Y-axis direction” is formed.
Since the A-shaped panel Pa shown in FIG. 1 has three stages, for convenience of explanation, the six short joists are referred to as an upper stage, a middle stage, and a lower stage as described below.
The distinction between upper, lower, and lower is referred to based on FIG. 1 (assuming the framework of the floor panel is a ladder), and is not up and down with respect to the earth.
As described above, XY is a horizontal coordinate axis, and a short joist parallel to the X axis has a horizontal posture.

Two middle short joists 2c and 2d are arranged along a line that bisects the longitudinal direction of the three long joists vertically (in this example, the XX axis),
Further, two upper short joists 2a and 2b and two lower short joists 2e and 2f are arranged so as to have a center line interval L with respect to the middle short joists (the center line interval is L). Therefore, the internal dimension is L-1.5w).
In this way, “four frames 7 with one side of the center line being L” are formed,
The four frames 7 are located in the center of the floor panel frame, and share two sides to form a “rice-shaped structure 9”.
Note the single frame 7 (see FIG. 1). The center line of the vertical and horizontal (XY) joists is a square with side length L. Therefore, the internal dimension in the horizontal direction (X-axis direction) is L-1.5w, and the internal dimension in the vertical direction (Y-axis direction) is L-w.

A portion corresponding to the upper and lower ends of the ladder has no short joists and a U-shaped structure 8 is formed. These U-shaped structures are oriented with the opening up or down in the figure. That is, it opens toward the longitudinal direction (Y-axis direction) of the floor panel Pa.
Considering the above-mentioned framework structure from another viewpoint, the entire framework of the floor panel Pa of this embodiment is a rectangle with a long side 4L and a short side 2L, the long side is formed with long joists, and the short side is formed with a core. Two of the letter-shaped structures are opened side by side.
For example, even when considering the case of laying tatami mats, it will be understood that it is practically convenient that the vertical / horizontal length relationship is 1: 2.
The details of the installation and support of the floor panel Pa will be described later with reference to FIG. 5. The longitudinal end (side of the length dimension 2L) is fixed in contact with the horizontal member 5, and the horizontal panel is fixed. Supported by material 5.

FIG. 2 is a manufacturing process explanatory diagram in which assembly symbols are written in the exploded plan view of the floor panel framework according to the embodiment shown in FIG.
Three long joists 1a, 1b, and 1c having a length dimension of 4L are prepared and set parallel to each other. Each of the three long joists is divided into four equal parts in the length direction, and a connection point c is determined for each distance L.
Separately from the above, six short root joists 2a, 2b to 2f having a length dimension L-1.5w are created, and each of these short joists is bridged between the long roots and fixed.
The above fixing is performed by bringing both ends of the short joist into contact with the connection portion c of the long joist and applying an appropriate known technique such as nailing, for example. This completes the framework of the floor panel according to the present embodiment.

FIG. 3 is an exploded perspective view for explaining a manufacturing process of the main structural portion including the frame shown in FIG. 1 described above, and depicts an installation posture of the floor panel according to the present invention. That is, the upper part of the figure is also above the earth, and the long and short joists forming the framework of the A-shaped floor panel are installed in a horizontal posture. 3A is an attachment process diagram of the backing plate, and FIG. 3B is an attachment process diagram of the rectangular heat insulating plate.
(A) As shown in the figure, from the lower side of the three long joists 1a, 1b, 1c, the substantially equal-length backing plates 3a, 3b, 3c are attached in contact with each other.
Although the backing board in this embodiment used the plywood, when implementing this invention, it is not limited to a plywood, For example, a fiber board and a metal plate can also be used.

(B) is a partially enlarged view of FIG. (A), in which three long joists are not distinguished from each other, and are denoted by reference numeral 1. Similarly, six short joists are not distinguished from each other by reference numeral 2. Is attached.
As shown in this figure, at least one side edge projects from the lower surface of the long joist 1 in the width direction of the backing plate 3. In FIG. 3B, 3a surrounded by a chain line is an overhanging portion.
As described above with reference to FIG. 1, in the inner method of the frame 7 of the floor panel Pa of the present embodiment, the side length dimensions are L-1.5w and L-w.
Therefore, a rectangular heat insulating plate 4 having side lengths L-1.5w and L-w drawn by a solid line in FIG. 5B is formed and fitted into the frame 7 as indicated by arrows a and a.
The fitted rectangular heat insulating plate 4 is supported by the overhanging portion 3 a of the backing plate 3.
Although it is a well-known structure only by attaching the backing plate to the joist, as in the present invention, “the backing plate that protrudes from the underside of the joist to the side” is formed by forming a frame or a U-shaped structure. The structure of attaching to the lower surface of the long joist and supporting the rectangular heat insulating plate is a structure unique to the present invention.

Similarly, the rectangular heat insulating plate 4 ′ drawn with phantom lines is fitted into the U-shaped structure 8 as indicated by arrows b and b. Thereby, the floor panel provided with heat insulation is manufactured.
In the floor panel Pa of this embodiment, since a heat insulating member is incorporated in the panel itself, when the floor panel is laid on a horizontal member and installed side by side, a heat insulating structure of the floor is immediately completed. In this way, a floor structure with a heat insulating structure can be constructed quickly and easily, and labor costs can be reduced.
In addition, the heat insulation member can be transported, stored and managed remarkably, and there is no risk of mistakes in the flooring work.
The thickness dimension t of the rectangular heat insulating plate 4 is smaller than the joist dimension H. Thus, when a face material (not shown in FIG. 3 is omitted, will be described in detail later with reference to FIG. 6) is stretched on the floor panel framework, a gap is created between the face material and the rectangular heat insulating plate, Insulation is further improved.

The basic principle of the present invention is “to remove a single joist from a square frame formed with four joists to make a U-shaped structure, thereby reducing the volume without impairing the rigidity”. .
A modification of the floor panel Pa (FIG. 1) can be considered by applying this principle. FIG. 4 is a plan view illustrating the B-type floor panel Pb and the C-type floor panel Pc as compared with the A-type floor panel Pa (for the sake of convenience of reading, the width of the joists is shown enlarged). .
The A-shaped floor panel Pa forms four frames and four U-shaped structures by three long joists having a length dimension of 4L and six short joists having a length dimension of L-1.5w. Whereas
The B-shaped floor panel Pb forms two frames and four U-shaped structures by three long joists having a length of 3L and four short joists having a length of L-1.5w. And
The C-shaped floor panel Pc forms four U-shaped structures by three long joists having a length dimension 2L and two short joists having a length dimension L-1.5w.
All floor panels have a width dimension of about 2 L in the X-axis direction.
Each of the above three types of floor panels has a U-shape with no short joists at the upper and lower ends of the figure. By omitting the short joists as described above, the material volume can be reduced, the rigidity is high, and the rigidity distribution is uniform.

FIG. 5 shows a process of laying and arranging the floor panels according to the embodiment shown in FIG. 4 described above, and (A) is a diagram depicting a horizontal member as a preparatory work for installing the floor panels. (B) is a schematic plan view showing a state in which a floor panel is laid on the horizontal member, with movable partitions added thereto.
In the example of this figure, six A-shaped floor panels Pa described with reference to FIG. 1 are arranged, and further four B-shaped floor panels Pa and two C-shaped floor panels Pc are arranged. Yes.
[Refer FIG. 5 (A)], many horizontal members 5 are arrange | positioned in the X-axis direction and the Y-axis direction. In this example, the distance dimensions in the Y-axis direction are 2L, 3L, and 4L.
Generally speaking, the interval dimension in the Y-axis direction is mL (m is an integer of 2 or more). In practice, m = 4 is most useful, and m = 3 is also used. m = 2 is used as an auxiliary.
The dimension L is as described with reference to FIG. 1, and the X-axis and Y-axis are horizontal orthogonal coordinate axes as in FIG.
The interval dimension of the horizontal member in the X-axis direction is an integral multiple of 2L, that is, 2nL (n is an integer of 1 or more) (see FIGS. 1 and 4) 2L is the width dimension of the floor panel. Accordingly, “n” of 2nL means the number of floor panels arranged in the width direction.
In addition, when saying the space | interval dimension of a horizontal member, there is a difference between saying by a centerline space | interval and an internal dimension. When the horizontal member interval is represented by L, even if there is an error of about the width dimension w of the horizontal member, it belongs to the technical scope of the present invention.

[See FIG. 5B] In this embodiment, basically, three A-shaped floor panels Pa are arranged in one section formed of the horizontal member 5, and the B-shaped floor panel Pb is also arranged in the other sections. Or a C-shaped floor panel Pc. As a result, a large number of cells are formed. In this way, the grid of one side dimension L is laid with no gap over the floor construction planned area.
As a result, the rigidity distribution is uniform over the entire floor surface.
I refused to say "basic" here, because special purpose rooms (such as bathrooms and toilets) do not have normal flooring, so general rooms other than such areas are said to be Meaning.
By appropriately using each type of floor panel (A type, B type, C type) as in this example, it is possible to supply a floor assembly that fits any floor plan in response to various requests of users. it can.

Conventionally, an indoor partition is generally provided on a horizontal member. If this is not done, conventional joists cannot withstand the weight of the partition member.
However, in the present embodiment (see FIG. 5B), the entire floor surface of a normal room is covered with a strong mesh (specifically, the frame 7 and the U-shaped structure 8 described in FIG. 1). Therefore, it is not always necessary to be directly above the horizontal member 5, and the movable partition 6 can be disposed on the mesh. That is, the movable partition 6 can be disposed above (or not necessarily directly above) the long joists or short joists of the arranged floor panels.
The length of one side of the square formed by the long joists and the short joists is L. In this embodiment, L = 455 mm, and the partition member itself has a certain degree of rigidity, so that the movable partition can be provided at almost any position in practical use.

FIG. 6 is an explanatory diagram of the work of placing a face material on the floor panel Pa according to the present invention. However, only a part of the construction (part corresponding to two floor panels) is extracted and drawn.
As shown in (A), two floor panels Pa are arranged side by side in the X-axis direction. On the other hand, the two face members 10 are arranged in the Y-axis direction and pasted on the floor panel (arrow α). A plan view of this is as shown in (B). That is, the joint of the two floor panels Pa is in the Y-axis direction, and the joint of the two face materials 10 is in the X-axis direction.
In this way, since the joints of the floor panels and the joints of the face materials are orthogonal to each other, there is no strength in the directionality, and the flatness of the entire floor surface is eliminated. Will improve.

FIG. 6 shows an example in which two floor panels and two face materials overlap in the same shape so that the principle of the present invention (Claim 8) is easy to understand. As shown in this figure, the present invention is not limited to “two / two” pairs. In short, it is effective to shift the floor panel joint and the face material joint.
