Mode for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be exemplified and described with reference to the drawings.

[0016] As shown in FIGS. 1 to 7, in one embodiment of the present invention, the building wood 1 has a finished surface 2 and a fire-resistant flow path 3. The fire-resistant flow path 3 has an inlet 4 connected to a water supply pipe, an outlet 6 connected to a drain pipe 5, and a hollow parallel flow path 7 that communicates with the inlet 4 and the outlet 6 and extends parallel to the finished surface 2. During a fire, water flowing from the water supply pipe is discharged from the drain pipe 5 through the parallel flow path 7.

[0017] In this embodiment, the building timber 1 is a flooring material. Therefore, the finished surface 2 of the building timber 1 is perpendicular to the vertical direction and is formed by the upper surface of the building timber 1. The building timber 1 is not limited to flooring material, but may also be used as ceiling material or wall material, for example. The building timber 1 is not limited to such surface material, but may also be used as beam material or column material, for example.

[0018] As shown in Figure 8, the drain pipe 5 is connected to the outlet 6 by being fixed to the building timber 1 with screws, which are fasteners 8. The water supply pipe is connected to the inlet 4 by being fixed to the building timber 1 with screws, which are fasteners 8, in the same way as the drain pipe 5. The method of fixing the drain pipe 5 and the water supply pipe is not limited to using fasteners 8; for example, adhesive may be used.

[0019] According to the above configuration, in the event of a fire, water supplied from the water supply pipe is discharged from the drain pipe 5 through the parallel channel 7. This allows new water to be introduced into the parallel channel 7 from the inlet 4 while the water in the parallel channel 7, which has been heated by the heat of the fire, is discharged from the outlet 6, thereby cooling the finished surface 2. Furthermore, by adjusting the flow rate of water in the fire-resistant channel 3, the desired fire resistance can be obtained. Therefore, compared to cases where fire resistance, semi-fire resistance, or other fire resistance properties are given to building timber 1 by applying or absorbing fire-resistant agents to the wood, or by laminating wood with fire-resistant material, it is possible to realize building timber 1 with fire resistance that is superior in terms of reducing carbon dioxide emissions and reusability. In addition to fire resistance, building timber 1 may also be configured to exhibit non-combustible properties such as non-combustible material, semi-non-combustible material, or flame-retardant material.

[0020] The discharge port 6 opens into the finished surface 2. With the above configuration, the need to provide the discharge port 6 on the surface 9 opposite to the finished surface can be reduced, making it easier to ensure the aesthetic appeal of the surface 9 opposite to the finished surface. The discharge port 6 may also be configured to open into the surface 9 opposite to the finished surface. With the above configuration, the need to provide the discharge port 6 on the finished surface 2 can be reduced, making it easier to ensure the aesthetic appeal of the finished surface 2. The discharge port 6 may also be provided on a surface different from both the finished surface 2 and the surface 9 opposite to the finished surface. With the above configuration, the need to provide the discharge port 6 on both the finished surface 2 and the surface 9 opposite to the finished surface can be reduced, making it easier to ensure the aesthetic appeal of both the finished surface 2 and the surface 9 opposite to the finished surface. In this embodiment, one discharge port 6 is provided on the finished surface 2, but the number and arrangement of the discharge ports 6 can be set as appropriate.

[0021] The inlet 4 opens into the finished surface 2. With the above configuration, the need to provide the inlet 4 on the surface 9 opposite to the finished surface can be reduced, making it easier to ensure the aesthetic appeal of the surface 9 opposite to the finished surface. The inlet 4 may also be configured to open into the surface 9 opposite to the finished surface. With the above configuration, the need to provide the inlet 4 on the finished surface 2 can be reduced, making it easier to ensure the aesthetic appeal of the finished surface 2. The inlet 4 may also be provided on a surface different from both the finished surface 2 and the surface 9 opposite to the finished surface. With the above configuration, the need to provide the inlet 4 on both the finished surface 2 and the surface 9 opposite to the finished surface can be reduced, making it easier to ensure the aesthetic appeal of both the finished surface 2 and the surface 9 opposite to the finished surface. In this embodiment, one inlet 4 is provided on the finished surface 2, but the number and arrangement of the inlet 4 are not limited to this and can be set as appropriate.

[0022] The parallel flow path 7 has a group of flow paths 7a consisting of a plurality of flow paths 7a1 that are arranged laterally along the finished surface 2 and extend vertically parallel to each other, and a flow path connection part 7b that allows all of the plurality of flow paths 7a1 to pass through each other laterally. With the above configuration, the temperature of the finished surface 2 can be cooled more efficiently by flowing water through the plurality of flow paths 7a1 and the flow path connection part 7b.

[0023] In this embodiment, the predetermined direction along the finished surface 2 is referred to as the vertical direction, and the direction along the finished surface 2 and perpendicular to the vertical direction is referred to as the horizontal direction.

[0024] The inlet 4 is provided at the intersection of the channel group 7a and the channel connection section 7b. With this configuration, water can be efficiently passed through the parallel channel 7. The outlet 6 is provided at the intersection of the channel group 7a and the channel connection section 7b. With this configuration, drainage from the parallel channel 7 can be efficiently performed. Note that the positions of the inlet 4 and outlet 6 are not limited to the intersection of the channel group 7a and the channel connection section 7b.

[0025] The flow path connection section 7b is composed of an upstream connecting flow path 7b1 that allows all of the multiple flow paths 7a1 of the flow path group 7a to pass through each other laterally on the upstream side, and a downstream connecting flow path 7b2 that allows all of the multiple flow paths 7a1 of the flow path group 7a to pass through each other laterally on the downstream side. With this configuration, water can be efficiently passed through the entire parallel flow path 7.

[0026] The inlet 4 is located at the intersection of the flow channel group 7a and the upstream connecting flow channel 7b1, and the outlet 6 is located at the intersection of the flow channel group 7a and the downstream connecting flow channel 7b2. With this configuration, water can be passed through the entire parallel flow channel 7 even more efficiently.

[0027] The fire-resistant flow path 3 may have multiple inlets 4 connected separately to multiple water supply pipes, multiple outlets 6 connected separately to multiple drain pipes 5, and a hollow parallel flow path 7 that connects to the multiple inlets 4 and multiple outlets 6 and extends parallel to the finished surface 2, and may be configured to discharge water from the multiple water supply pipes through the parallel flow path 7 to the multiple drain pipes 5 in the event of a fire. The number of water supply pipes and inlets 4 may be the same as or different from the number of drain pipes 5 and outlets 6.

[0028] The building timber 1 discharges the water flowing through the parallel channel 7 from the drain pipe 5 without spraying it outside the building timber 1. Alternatively, the building timber 1 may be configured to discharge the water flowing through the parallel channel 7 from the drain pipe 5 while spraying it outside the building timber 1 (for example, from the finished surface 2 or the surface 9 opposite the finished surface).

[0029] The building timber 1 has a first board portion 10 and a second board portion 11, the second board portion 11 has a finished surface 2, and the first board portion 10 has a surface 9 opposite to the finished surface. The first board portion 10 and the second board portion 11 are each formed from sawn timber, laminated veneer timber, plywood, glued laminated timber, or cross-glued laminated timber, or any combination thereof. In this embodiment, the first board portion 10 is formed from laminated veneer timber, and the second board portion 11 is formed from cross-glued laminated timber. The first board portion 10 and the second board portion 11 may each be made from a single piece of sawn timber. The type of wood that constitutes the building timber 1 is not particularly limited.

[0030] The first plate portion 10 has a groove-forming surface 10b having a plurality of grooves 10a that form part of the flow channel group 7a, and the second plate portion 11 has a joining surface 11a that is joined to the groove-forming surface 10b and forms another part of the flow channel group 7a. The plurality of grooves 10a are arranged laterally and extend vertically parallel to each other. The groove-forming surface 10b has a connecting groove portion 10c that forms part of the flow channel connection portion 7b, and the joining surface 11a forms another part of the flow channel connection portion 7b. The connecting groove portion 10c is composed of an upstream connecting groove 10d that intersects with the plurality of grooves 10a and extends laterally to form part of the upstream connecting flow channel 7b1, and a downstream connecting groove 10e that intersects with the plurality of grooves 10a and extends laterally to form part of the downstream connecting flow channel 7b2.

[0031] In this embodiment, the second plate portion 11 has a finished surface 2 and the first plate portion 10 has a surface 9 opposite to the finished surface. However, the opposite configuration is also possible, where the first plate portion 10 has a finished surface 2 and the second plate portion 11 has a surface 9 opposite to the finished surface. Alternatively, the first plate portion 10 may be provided on both sides of the second plate portion 11.

[0032] Multiple grooves 10a are formed by cutting into the wood, and the longitudinal end faces of the grooves 10a are formed by wood inlays 12. The longitudinal end faces of the grooves 10a may also be formed by uncut portions. The connecting grooves 10c are formed by cutting into the wood, and the longitudinal end faces of the connecting grooves 10c are formed by wood inlays 12. The longitudinal end faces of the connecting grooves 10c may also be formed by uncut portions. With the above configuration, it is possible to easily realize building timber 1 of a desired size that can efficiently cool the finished surface 2.

[0033] The first plate section 10 and the second plate section 11 are fixed together at their contact points with adhesive. Each of the first plate section 10 and the second plate section 11 consists of multiple pieces of wood, with the multiple pieces of wood constituting the first plate section 10 fixed together with adhesive, and the multiple pieces of wood constituting the second plate section 11 fixed together with adhesive. With this configuration, by appropriately setting the number of pieces of wood for the first plate section 10 and the second plate section 11, it is possible to easily realize building timber 1 of a desired size and thickness that can efficiently cool the finished surface 2. Furthermore, the need to use metal fittings such as screws and nails is reduced, the reusability of the building timber 1 can be further improved, and the aesthetic appeal of the building timber 1 can be easily ensured. Note that the first plate section 10 and the second plate section 11 may each be made from a single piece of lumber, with the contact points between them fixed together with adhesive. The same effect can be obtained with this configuration as well. In addition, the first plate section 10 and the second plate section 11 may be fixed together using metal fittings such as screws and nails in addition to adhesive. The multiple pieces of wood constituting the first board section 10, or the multiple pieces of wood constituting the second board section 11, may be fixed together using screws, nails, or other metal fasteners in addition to adhesive.
