DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] 1 is a perspective view showing an example of the internal structure of a wooden building 1 according to an embodiment. In the wooden building 1 of this embodiment, a dummy column 4 and a partition wall 5 are removably provided between a ceiling part 2 and a floor board 3. The ceiling part 2 is provided with a plurality of beams 21, 22 arranged in a lattice pattern.

[0013] The dummy column 4 is a detachable column that does not support the load of the ceiling section 2. The upper end of the dummy column 4 is fixed to the ceiling section 2, and the lower end of the dummy column 4 is fixed to the floor board 3.

[0014] The partition wall 5 is a removable wall that is erected adjacent to the dummy column 4. The upper end of the partition wall 5 is supported by beams 21 and 22.

[0015] The dummy columns 4 are disposed below the intersections of the beams 21, 22 arranged in a lattice pattern. The partition walls 5 are disposed below the linear portions between two adjacent intersections.

[0016] 2 is a plan view showing planned arrangement areas 4R, 5R of the dummy column 4 and the partition wall 5 on the floorboard 3. The planned arrangement area 4R is an area where the dummy column 4 is planned to be arranged, and the planned arrangement area 5R is an area where the partition wall 5 is planned to be arranged.

[0017] By selectively placing dummy columns 4 and partition walls 5 in the intended placement areas 4R, 5R of the floorboard 3, it is possible to freely change the indoor layout.

[0018] The arrangement regions 4R and 5R correspond to the beams 21 and 22. Specifically, the arrangement region 4R corresponds to an intersection of the beams 21 and 22 arranged in a lattice pattern, and the arrangement region 5R corresponds to a linear portion between two adjacent intersections. The arrangement regions 4R and 5R correspond to a projection region obtained by projecting the beams 21 and 22 downward.

[0019] A positioning tool 6 for positioning the dummy column 4 is placed in the intended placement area 4R of the floorboard 3. The dummy column 4 is placed on the positioning tool 6. A plurality of female screws 32 for fixing the positioning tool 6 to the floorboard 3 are embedded in the intended placement area 4R.

[0020] A rail 7 for positioning the partition wall 5 is placed in the intended placement area 5R of the floorboard 3. The lower end of the partition wall 5 engages with the rail 7. The rail 7 is placed between two adjacent positioning fixtures 6, and an end of the rail 7 is connected to the positioning fixtures 6.

[0021] Fig. 3 is a perspective view showing a configuration example of the dummy pillar 4 and the pin 8. The figure shows the underside 41 of the dummy pillar 4. The dummy pillar 4 has a hole 4a extending upward from the underside 41. The pin 8 is inserted into the hole 4a of the dummy pillar 4 so as to be movable up and down.

[0022] The dummy pillar 4 is a rectangular pillar made of wood. The pin 9 is, for example, a metal pipe. The hole 4a of the dummy pillar 4 has a length equal to or greater than that of the pin 8.

[0023] The hole 4a and the pin 8 have a shape and size that allow for a clearance fit. The hole 4a and the pin 8 have, for example, a circular cross-sectional shape. When the dummy pillar 4 is erected with the hole 4a facing downward, the pin 8 descends under its own weight.

[0024] 4 is a plan view showing a configuration example of the positioning tool 6. The positioning tool 6 is plate-shaped, and is placed on the floor board 3 with its main surface facing up and down, and is attached to the floor board 3. The positioning tool 6 is formed of, for example, a metal plate. The positioning tool 6 is, for example, rectangular in shape and approximately the same size as the lower surface 41 of the dummy column 4.

[0025] An opening 6a is formed in the center of the positioning tool 6, penetrating in the plate thickness direction. The opening 6a is, for example, circular. Similar to the hole 4a of the dummy column 4, the opening 6a has a shape and size that allows the pin 8 to be inserted therein.

[0026] The positioning tool 6 has a plurality of notches 6b formed on its outer edge for fitting the ends of the rail 7 (see FIG. 2). The notches 6b are formed in a U-shape or a C-shape extending from the outer edge toward the central opening 6a. The rail 7 is made of, for example, metal and has a thickness similar to that of the positioning tool 6.

[0027] Specifically, four notches 6b are formed in the centers of four sides of the rectangular positioning tool 6. The four notches 6b are formed, for example, so as to be four-fold symmetrical about the opening 6a.

[0028] The cutouts 6b may further include a notch that indicates the center. Also, any one of the cutouts 6b may be connected to the opening 6a.

[0029] A plurality of screw holes 6c are formed around the opening 4a of the positioning tool 6 for inserting male screws (not shown) that fix the positioning tool 6 to the floorboard 3. These screw holes 6c are located, for example, on diagonals of the rectangular positioning tool 6.

[0030] The screw hole 6c corresponds to a female screw 32 (see FIG. 2) embedded in the floorboard 3. The positioning tool 6 is fixed to the floorboard 3 by passing a male screw through the screw hole 6c and fastening it to the female screw 32. This is not limited to this, and a screw may be passed through the screw hole 6c and fastened directly to the floorboard 3.

[0031] Further around the screw hole 6c, a plurality of screw holes 6d are formed for fixing another member, in place of the dummy column 4, to the floorboard 3 together with the positioning tool 6. The other member may be, for example, a flange provided on the leg of a piece of furniture.

[0032] 5A and 5B are cross-sectional views for explaining the positioning of the dummy column 4 by the pin 8 and the positioning tool 6. These drawings show a cross section of the pin 8 and the positioning tool 6 cut along the line VV in FIG.

[0033] 5A, the lower surface 41 of the dummy pillar 4 and the lower end of the pin 8 are placed on the upper surface of the positioning tool 6, and in this state, the dummy pillar 4 is moved toward the center of the positioning part 6. At this time, the pin 8 is retracted inside the hole 4a of the dummy pillar 4.

[0034] 5B, when the dummy pillar 4 moves to a position on the positioning tool 6 where the hole 4a and the opening 6a are connected, the pin 8 drops from the hole 4a, and the lower end of the pin 8 protruding downward from the lower surface 41 is inserted into the opening 6a. This positions the dummy pillar 4.

[0035] The upper end of the dummy column 4 is fixed to a pin (not shown) extending downward from the intersection of the beams 21, 22 (see FIG. 1). For example, a pin is accommodated inside a groove formed in the upper end of the dummy column 4, the groove being open to one side surface and the top surface, and the upper end of the dummy column 4 is fastened to the pin.

[0036] When removing the dummy column 4, the upper end of the dummy column 4 is released from the fixation and the dummy column 4 is tilted, so that the lower end of the pin 8 comes out of the opening 6a of the positioning tool 6, and the fixation of the lower end of the dummy column 4 is released.

[0037] Without being limited to this, a positioning device 6 having one of the notches 6b connected to the opening 6a may be used to insert a rail 7 or something of a similar shape from the notch 6b to the opening 6a, and the lower end of the pin 8 may be pushed up to release the fixation of the lower end of the dummy column 4.

[0038] Fig. 6 is a cross-sectional view showing an example of the configuration of the partition wall 5 and the rail 7. This figure shows a cross section of the partition wall 5 and the rail 7 taken along line VI-VI in Fig. 2. A recess 5b is formed in the lower surface 51 of the partition wall 5, and the rail 7 fits into the recess 5b to position the partition wall 5.

[0039] Fig. 7 is a plan view showing an example of the configuration of a ruler 9 for marking the intended placement area 4R of the dummy pillar 4 on the floorboard 3. The ruler 9 has a notch 9b formed therein that indicates the center position of the intended placement area 4R. The notch 9b corresponds to the notch 6b of the positioning tool 6 (see Fig. 4).

[0040] The ruler 9 also has a plurality of holes 9c that indicate positions for embedding female screws 32 (see FIG. 2). The ruler 9 may also have positioning holes 9a formed in the floorboard 3 and into which dowels are inserted, in addition to positioning holes (not shown).

[0041] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made by those skilled in the art. [Explanation of symbols]
