Mode for Carrying Out the Invention

[0017] Embodiments of the present invention (hereinafter, these embodiments) will be described in detail based on the drawings. The drawings may schematically represent the width, thickness, shape, etc. of each part compared to the actual aspect, but are merely examples and do not limit the interpretation of the present invention.

[0018] FIG. 1 is an external perspective view showing a temporary building 100 according to these embodiments. The temporary building 100 may be a log house constructed by stacking a plurality of log materials for walls by a log construction method or the like.

[0019] The temporary building 100 may be used, for example, as an office installed near a construction site. Further, after the construction is completed, the temporary building 100 may be relocated near another construction site. In order to relocate the temporary building 100, a plurality of log materials for walls taken out by disassembling the temporary building 100 may be loaded onto the loading platform of a transportation vehicle such as a truck and transported. Then, the plurality of transported log materials for walls may be assembled near the construction site of the transportation destination and reused as an office.

[0020] When transporting dismantled wall logs, it would be ideal to use boxes to efficiently move multiple wall logs together onto a truck bed. However, preparing separate boxes capable of holding wall logs would increase the overall volume of materials.

[0021] Therefore, it is conceivable to combine some of the wall log materials included in the temporary building 100 to form a box capable of housing the wall log materials. For example, the dimensions of the cargo bed of a 4-ton truck are approximately 6 to 8 meters in length and approximately 2.2 meters in width. Therefore, it would be ideal to form a box with a length of approximately 1.1 meters in the shorter direction, and then place two of these boxes side by side in the width direction to load them onto the truck bed.

[0022] However, most of the wall logs included in the temporary building 100 are only about 4 to 6 meters long. In this embodiment, the temporary building 100 is a building with a width of approximately 9 meters in the front-to-back direction and approximately 5 meters in the left-to-right direction. Therefore, it is difficult to form a box of an appropriate size for loading onto a 4-ton truck using the wall logs included in the temporary building 100.

[0023] Therefore, in this embodiment, a transport box is formed using log materials different from the wall log materials included in the temporary building 100. Specifically, the log materials used to make up the desks used inside the temporary building 100 are used as the different log materials.

[0024] In the following explanation, the entrance E side of temporary building 100 will be referred to as the "front side," and the opposite side as the "rear side." Furthermore, the right side when viewing the front from the rear side will be referred to as the "right side," and the left side when viewing the front from the rear side will be referred to as the "left side."

[0025] Figure 2 schematically shows the front wall as seen from the front. Figure 3 schematically shows the rear wall as seen from the front. Figure 4 schematically shows the partition wall as seen from the front. Note that the notches in the log materials for each wall shown in Figures 2 to 4 are not shown.

[0026] The temporary building 100 includes a front wall 10, a rear wall 20, a partition wall 30, a front left wall 41L, a rear left wall 42L, a front right wall 41R, and a rear right wall 42R.

[0027] In this embodiment, the longest log material among the wall logs included in the temporary building 100 is used for the front wall 10, the rear wall 20, and the partition wall 30. Furthermore, any wall logs included in the temporary building 100 that are shorter than the long log material are referred to as short log materials. Short log materials are the log materials included in the temporary building 100 other than the long log material.

[0028] Each wall log included in the temporary building 100 is a plate-like material with a thickness of approximately 9 centimeters, and has at least one pair of notches formed on it, spaced apart from each other in the longitudinal direction. The notches are the parts into which grooves are formed into which other log materials are fitted. Two wall logs are arranged so as to intersect each other, and their notches are joined together. The wall logs are stacked in the height direction to form the exterior and interior walls of the temporary building 100. In this embodiment, the log material has a roughly rectangular cross-section, but the cross-sectional shape of the log material is not limited to this.

[0029] As shown in Figure 2, the front wall 10 includes multiple wall logs stacked in the height direction. The front wall 10 also has an opening that serves as the entrance E to the temporary building 100. Of the wall logs included in the front wall 10, the long logs 11 are used above the entrance E. Specifically, the front wall 10 includes five long logs 11. In addition to the five long logs 11, the front wall 10 is composed of eight short logs 12.

[0030] As shown in Figure 3, the rear wall 20 includes multiple wall logs stacked in the height direction. The rear wall 20 includes nine long logs 21. In addition to the nine long logs 21, the rear wall 20 is composed of two short logs 22.

[0031] As shown in Figure 4, the partition wall 30 includes wall logs for partitioning the space on the first floor in the front-to-back direction, and wall logs for partitioning the space on the second floor in the front-to-back direction. In the partition wall 30, the wall log provided at the top of the first floor is a long log 31. That is, the partition wall 30 includes one long log 31. In addition to the one long log 31, the partition wall 30 is composed of 18 short logs 32.

[0032] As explained above, the temporary building 100 includes 15 long log members B1 to B15. These 15 long log members should have a common shape and size.

[0033] Figure 5 is a plan view showing long log members. As shown in Figure 5, each of the long log members 11, 21, and 31 has a pair of notches n1 that are spaced apart from each other in the longitudinal direction, and a pair of notches n1 that are facing each other in the short direction. In other words, each of the long log members 11, 21, and 31 has four notches n1 formed on it.

[0034] The length L1 of the long log material should be the longest among the wall log materials included in the temporary building 100. Furthermore, the length L2 between the notches n1 of the long log material should be longer than any of the lengths of the wall log materials included in the temporary building 100. Length L2 is the length between the end faces that form the groove, as shown in Figure 5. The box B described later can accommodate log materials shorter than length L2.

[0035] Figure 6 is a perspective view showing an example of a desk D to be installed inside the temporary building 100. The desk D should be assembled using a construction method similar to log construction, as is the case with the temporary building 100. The desk D includes two legs and a support section that supports these legs. Each of the two legs is composed of two leg logs D1. The support section is composed of one support log D2. Therefore, the desk D consists of four leg logs D1 and one support log D2. Furthermore, the desk D may have a tabletop placed on top of the leg logs D1, as shown by the dashed lines in Figure 6.

[0036] Figure 7 is a plan view showing the log materials that make up the desk D. As shown in Figure 7, one notch n2 is formed in the leg log material D1. In addition, a pair of notches n2 are formed in the support log material D2, spaced apart from each other in its longitudinal direction, and facing each other in its short direction. In other words, four notches n2 are formed in the support log material D2. It is preferable that the notches n2 have the same shape and size as the notches n1 shown in Figure 5.

[0037] The length L3 of the support log D2 should be shorter than any of the wall logs included in the temporary building 100. By using shorter logs as side panels for box B, it is possible to prevent box B from becoming too large. Also, the length L4 of the leg log D1 should be shorter than the length L3 of the support log D2. This prevents the depth of desk D from becoming too long.

[0038] Figure 8A is a perspective view showing an example of a box B for housing log materials. Figure 8B is an exploded perspective view showing an example of a box B for housing log materials. Figures 8A and 8B show an example in which the housing member, box B, is composed of four long log materials 11, four box log materials A1, and two support log materials D2. The box log materials A1 are log materials prepared separately to form the box, with a pair of notches formed on them. The length of the box log materials A1 in the longitudinal direction is the same as the length of the support log materials D2 in the longitudinal direction, and the positions where the notches are formed in the longitudinal direction are also common. The box B may be assembled using a construction method similar to the log construction method, similar to the temporary building 100.

[0039] One side panel extending in the longitudinal direction of box B is composed of two long log pieces 11 (B1 and B2) stacked in the height direction. The other side panel extending in the longitudinal direction of box B is composed of two long log pieces 11 (B3 and B4) stacked in the height direction.

[0040] Long log members B1 and B2 are joined to each other via supporting log member D2. Long log members B3 and B4 are joined to each other via supporting log member D2.

[0041] Here, we will explain the assembly procedure for box B. First, dismantle the temporary building 100 and desk B, which will be installed inside the temporary building 100, and take out several wall logs and furniture logs. Also, prepare box log A1 separately.

[0042] Next, the box log A1 is positioned with its notch facing upwards, and the notch n1 of the long log 11 is fitted into the notch of the box log A1. In this state, the notch n1 is located at the top of the long log 11. Then, the notch n2 of the support log D2 is fitted into the notch n1 located at the top of the long log 11. In this state, the notch n2 is located at the top of the support log D2. Then, the notch n1 of the long log 11 is fitted into the notch n2 located at the top of the support log D2. In this state, the notch n1 is located at the top of the long log 11. Finally, the notch of the box log A1 is fitted into the notch n1 located at the top of the long log 11. By performing the above steps at each intersection (corner) of box B, box B is formed.

[0043] In the state shown in Figure 8A, the bottom and top of box B are open. Therefore, it is advisable to provide a board to close the bottom. In this case, the board should be fixed to the long log 11 or the box log A1 by nailing or the like. The board may be, for example, the wood that makes up the floor (not shown) of the first or second floor of the temporary building 100. Note that the bottom does not have to be completely closed, but should be closed to the extent that no gap is formed through which the short log slabs can fall.

[0044] It is preferable to form four boxes similar to box B shown in Figure 8A. The second box may consist, for example, of four long logs 11, 21 (B5~B8), four box logs A1, and two support logs D2. The third box may consist, for example, of four long logs 21 (B9~B12), four box logs A1, and two support logs D2. The fourth box may consist, for example, of three long logs 21, 31 (B13~B15), spare long logs, four box logs A1, and two support logs D2. The spare long logs may be logs of the same shape and size as long logs 11. Also, eight support logs D2 are needed to form four boxes B. Therefore, it is preferable to install eight or more desks D inside the temporary building 100.

[0045] In the temporary building 100 according to this embodiment described above, it is possible to suppress the increase in the volume of materials and to form a box B of a size suitable for storage and transportation. The box B containing the wall logs can then be loaded onto the bed of a truck and transported to the relocation site of the temporary building 100. It is preferable to load two boxes B side by side in the width direction onto the bed of a 4-ton truck. It is preferable to use a crane or the like to load the boxes B onto the truck bed. Furthermore, the box B also functions as a storage box before transportation. By storing multiple wall logs together in the box B, the number of wall logs can be properly managed, and loss can be suppressed.

[0046] The multiple short log materials included in the temporary building 100 may be housed in one of the four boxes B. In this embodiment, in order to form a box B capable of housing all the short log materials, the longest of the multiple wall log materials included in the temporary building 100 was used as the side panel of box B. However, the side panel of box B is not limited to the longest wall log material. If the longest log material is not used as the side panel of box B, the longest wall log material may not be housed in box B but loaded separately onto the truck bed. Alternatively, the longest wall log material may be housed in box B at an angle.

[0047] Furthermore, in this embodiment, the side panels of box B are made of furniture logs used to construct a desk D installed inside the temporary building 100, but the embodiment is not limited to this. Furniture logs used to construct furniture other than a desk may be used for the side panels of box B. Also, the furniture, including the furniture logs, may be fixedly installed to the temporary building 100, or it may be installed in a movable manner without being fixed.

[0048] Furthermore, although this embodiment describes an example in which the box log material A1 is prepared separately, it is not limited to this. For example, instead of the box log material A1, log materials that constitute furniture installed inside the temporary building 100 may be used.

[0049] Furthermore, in this embodiment, an example is shown where the side panel of box B is constructed by stacking two long logs in the height direction, but it is not limited to this. The side panel of box B may be constructed by stacking three or more long logs in the height direction. [Explanation of symbols]
