DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] 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.

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

[0015] The dummy pillars 4 are placed under the intersections of the beams 21, 22 arranged in a grid pattern. The partition walls 5 are placed under the linear portions between two adjacent intersections. By selectively placing the dummy pillars 4 and the partition walls 5, it is possible to freely change the indoor layout.

[0016] Although the beams 21 and 22 appear to intersect, they do not actually intersect as will be explained below.

[0017] Fig. 2 is a bottom view showing a configuration example of the ceiling portion 2. Figs. 3 and 4 are diagrams showing a configuration example of the mounting fixture 6. Fig. 5 is a plan view showing an example of connection between the beams 21 and 22. Fig. 6 is a side view showing an example of connection between the beam 21 and the dummy column 4.

[0018] In this embodiment, one of the beams 21 and 22, the beam 22, is a dummy beam (hereinafter, referred to as the dummy beam 22). The dummy beam 22 is a detachable beam that does not support the load of the ceiling portion 2 or the upper portion thereof.

[0019] 2, the beams 21 extend in a first horizontal direction (up-down direction in the figure) and are arranged in a second horizontal direction (left-right direction in the figure) perpendicular to the first horizontal direction. The dummy beams 22 extend in the second horizontal direction between two adjacent beams 21.

[0020] A pair of mounting fixtures 6 for supporting the dummy beams 22 are attached to a pair of mutually facing side surfaces 213 of two adjacent beams 21 .

[0021] By making the dummy beams 22 detachable from the beams 21 and selectively arranging the dummy beams 22, the interior visibility of the upper part of the building can be improved. Also, the beams 21 and the dummy beams 22 can be made to look as if they are intersecting. Furthermore, together with the dummy columns 4 and the partition walls 5, the layout of the building can be freely changed.

[0022] Pin holes 21a extending upward from the lower surface are formed in the intersections C of the beams 21, i.e., the portions where the dummy beams 22 are arranged on one or both sides of the beams 21. Support pins 8 for attaching the upper ends of the dummy columns 4 (see FIG. 1) are inserted and fixed in the pin holes 21a.

[0023] Furthermore, a pin hole 21a may be formed in the linear portion L of the beam 21, that is, in the portion between the two intersection portions C, and a pin hole 22a may be formed in the dummy beam 22 as well.

[0024] 3 and 4, the mounting fixture 6 includes a plate-shaped flange 61 and a pin 62 that protrudes in the plate thickness direction from one main surface of the flange 61. The mounting fixture 6 is made of metal.

[0025] The flange 61 is, for example, rectangular in shape and approximately the same size as the end surface of the dummy beam 22. The pin 62 is, for example, cylindrical, and is provided in the center of the flange 61. A pin hole 6b into which a retaining pin 71 is inserted is formed at the tip of the pin 62 (see FIG. 5).

[0026] A plurality of screw holes 6a are formed around the pin 62 of the flange 61 for inserting male screws (not shown) that fix the mounting fixture 6 to the side surface 213 of the beam 21. These screw holes 6a are located on diagonal lines of the rectangular flange 61.

[0027] The screw hole 6a corresponds to a female screw 24 (see FIG. 6) embedded in a side surface 213 of the beam 21. The mounting fixture 6 is fixed to the side surface 213 of the beam 21 by passing a male screw (not shown) through the screw hole 6a and fastening it to the female screw 24. This is not limiting, and a screw may be passed through the screw hole 6a and fastened directly to the beam 21.

[0028] 5, the mounting fixture 6 is disposed so that the main surface of the flange 61 opposite the pin 62 is in contact with the side surface 213 of the beam 21, and is fixed to the side surface 213 of the beam 21. The pin 62 protrudes in the second horizontal direction (left-right direction in the figure) from the side surface 213 of the beam 21. The end of the dummy beam 22 is attached to the pin 62 of the mounting fixture 6 fixed to the side surface 213 of the beam 21.

[0029] Specifically, a pin groove 22b that is open to the top and end faces is formed at the end of the dummy beam 22, a pin 62 is housed in the pin groove 22b, and the dummy beam 22 and the pin 62 are connected by a retaining pin 71. The retaining pin 71 penetrates the side surface of the end of the dummy beam 22 in the first horizontal direction (the up-down direction in the figure) and passes through the pin hole 6b at the tip of the pin 62 housed in the pin groove 22b.

[0030] 5 and 6, a support pin 8 for attaching the upper end of the dummy column 4 is inserted and fixed into a pin hole 21a extending upward from the underside, which is formed at the intersection C of the beams 21. A part of the support pin 8 protrudes downward from the underside of the beams 21, and the dummy column 4 is attached to the protruding support pin 8.

[0031] The dummy column 4 is attached in the same manner as the dummy beam 22. Specifically, a pin groove 4b that is open on one of the side surfaces and the end surface is formed at the upper end of the dummy column 4, and a support pin 8 is housed in the pin groove 4b, and the dummy column 4 and the support pin 8 are connected by a retaining pin 73. The retaining pin 73 penetrates the side surface of the upper end of the dummy column 4 and is passed through the pin hole 8a at the tip of the support pin 8 housed in the pin groove 4b.

[0032] A fastening pin 72 is also used to fix the support pin 8. The fastening pin 72 penetrates the side surface 213 of the beam 21 and is passed through a pin hole (not shown) at the upper end of the support pin 8 housed in the pin hole 21a. As shown in FIG. 6, the mounting fixture 6 is attached so as to cover the fastening pin 72 on the side surface 213 of the beam 21. This makes it possible to hide the fastening pin 72.

[0033] 6, a slit 28 is formed on the side surface 213 of the beam 21 at a height that is the center of the mounting fixture 6 in the vertical direction. This slit 28 is used for positioning the mounting fixture 6 or the dummy beam 22. Note that the slit 28 does not necessarily have to be formed.

[0034] 7 is a diagram showing an example of how the partition wall 5 is supported. This diagram shows a cross section of the beam 21 and the partition wall 5 taken along line VII-VII in FIG. 2. An L-shaped engagement piece 51 is attached to the upper end of the partition wall 5, and the engagement piece 51 is inserted into a slit 27 formed in the lower surface of the beam 21, thereby positioning the partition wall 5. The partition wall 5 is also supported by a dummy beam 22 in a similar manner.

[0035] 8 is a diagram showing a modified example of the dummy beam 22. As shown in the figure, the mounting fixture 6 is also attached to the side surface 223 of the dummy beam 22, and another dummy beam (not shown) extending in a direction perpendicular to the dummy beam 22 may be further provided.

[0036] This can further improve the introspection of the upper part of the building. It can also be made to look as if two dummy beams 22 are intersecting. Furthermore, the layout of the building can be changed more freely.

[0037] In this example, multiple female screws 24 for attaching the mounting fixture 6 are embedded in the side 223 of the dummy beam 22, similar to the side 213 of the beam 21 (see Figure 6), and a slit 28 is formed at a height that is the center of the mounting fixture 6 in the vertical direction.

[0038] The retaining pins 71 to 73 shown in Fig. 5 and Fig. 6 may be, for example, draft pins. Furthermore, as shown in Fig. 9, the retaining pins 71 to 73 (draft pins) may have a thread groove cut on the outer circumferential surface 75 and a recess 76 formed on one end surface. The recess 76 is, for example, a hexagonal hole into which a hexagonal wrench is inserted to rotate the pin.

[0039] Such fastening pins 71 to 73 are inserted into or removed from beams, columns, etc. while being rotated. This makes it easy to insert and remove the fastening pins 71 to 73, and also makes it possible to repeatedly use the holes into which the fastening pins 71 to 73 are inserted. Such draft pins having thread grooves cut into their outer circumferential surface can also be used in general draft pin construction methods.

[0040] The fastening pins 71-73 may be longer than the width of the beam or pillar, and one or both ends may be attached to protrude from the side surface of the beam or pillar. Furthermore, eye nuts for rotating the fastening pins 71-73 may be attached to the ends of the fastening pins 71-73 protruding from the side surface of the beam or pillar.

[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.

[0042] In the above embodiment, an example was described in which dummy columns 4 and partition walls 5 were attached to beams 21, 22 arranged in a lattice pattern, making it possible to freely change the floor plan. However, in buildings in which the beams are not visible from the outside, wooden boards with slits formed therein may be attached in a lattice pattern to the ceiling, similar to the beams 21, 22, and the dummy columns 4 and partition walls 5 may be attached to those wooden boards.
