DETAILED DESCRIPTION OF THE INVENTION
[0010] Hereinafter, a method for installing charcoal material and an underfloor structure of a building according to an embodiment of the present invention will be described in detail with reference to the drawings. In each drawing, the same or equivalent parts are designated by the same reference numerals. In the embodiment, the term "building" is not limited to a house where people live, but also includes buildings and other structures that house equipment, instruments, facilities, etc. Below, an example will be described in which a wooden house is used as the building.
[0011] As shown in Figure 1, the underfloor structure 1 of the building in this embodiment comprises a continuous footing 2 installed on the ground GL, a plurality of bases 3 installed on the continuous footing 2, a plurality of joists 4 installed between the opposing bases 3, and a plurality of floor panels 5 installed on the bases 3 and the joists 4.
[0012] The continuous footing 2 is made of reinforced concrete and is a foundation that runs continuously along the wall of the building. The cross section of the continuous footing 2 is, for example, inverted T-shaped. Between the continuous footings 2, a concrete slab 2a is formed planar with respect to the ground GL so as to be integrated with the continuous footings 2.
[0013] The foundation 3 is a wooden block placed horizontally on the continuous footing 2. The foundation 3 is fixed to the continuous footing 2 by anchor bolts (not shown) embedded in the continuous footing 2. Columns 6 that support the roof of the building extend upward from the top surface of the foundation 3. The continuous footing 2 and the foundation 3 may be in direct contact with each other, or a foundation packing may be placed between them.
[0014] The joists 4 are wooden square timbers that transmit the load applied to the floorboards 5 to the continuous footing 2 and the foundation 3. Both ends of the joists 4 facing each other in the longitudinal direction are fixed to the side of the foundation (not shown) that extends perpendicular to the foundation 3 shown in Figure 1. The bottom of the joists 4 is supported from below by steel beams (not shown) that extend from the concrete slab 2a.
[0015] The floorboards 5 are boards that support the weight of people and objects from below in an indoor space. The floorboards 5 include, for example, structural plywood installed on the base 3 and joists 4, and a floor installed on the structural plywood.
[0016] An underfloor space extends between the floorboards 5 and the concrete floor 2a. Air vents 5a are formed in the floorboards 5 to allow air to flow in and out between the interior space and the underfloor space. The air vents 5a are, for example, floor louvers. In a floor louver, multiple plate-like members are attached parallel to each other so as to cover part of the opening.
[0017] Hereinafter, a characteristic configuration of an underfloor structure 1 for a building according to an embodiment will be described with reference to FIGS. A support member 4a is attached to each of the side surfaces of a pair of adjacent joists 4 that face each other. The support member 4a is a wooden board that extends in the longitudinal direction of the joists 4 and is attached to the joists 4 so that its width direction coincides with the width direction of the joists 4. The support member 4a is also attached to the side surface of the base 3 that faces the adjacent joists 4. The support member 4a is attached to the side surface of the joists 4 or the base 3, for example, with nails or adhesive.
[0018] The support material 4a attached to the side of one of the adjacent joists 4 and the support material 4a attached to the side of the other joist 4 are configured so that wire mesh 4b can be detachably placed on them. Similarly, the support material 4a attached to the side of the base 3 and the support material 4a attached to the side of the joist 4 adjacent to the base 3 are configured so that wire mesh 4b can be detachably placed on them.
[0019] The wire mesh 4b is an example of a breathable mesh member that can support the breathable bag B containing the carbonaceous material placed on it. The wire mesh 4b is not easily bent even when the breathable bag B containing the carbonaceous material is placed on it, and has enough strength to prevent the wire mesh 4b from falling off the pair of receiving members 4a. The wire mesh 4b may be a square mesh or a rectangular mesh that extends along the receiving members 4a. As an example, the wire mesh 4b is a square mesh with a mesh size of 6 mm and 150°. If the mesh is a square mesh, it is preferable to arrange multiple meshes along the receiving members 4a.
[0020] The carbonaceous material is charcoal itself or a material containing a carbonaceous material, such as pulverized wood charcoal, bamboo charcoal, coconut shell charcoal, or other pulverized charcoal, activated carbon obtained by physically or chemically treating any of these, or a mixture of any of these with other materials. The carbonaceous material may be, for example, a molded product obtained by solidifying powdered charcoal or a mixture of powdered charcoal and other materials. The breathable bag B may be a woven or knitted fabric, or may be a bag made of nonwoven fabric.
[0021] The underfloor structure 1 of the building according to the embodiment has the above-mentioned configuration, so the concrete floor 2a does not interfere with the work of workers working in the underfloor space. Also, the breathable bags B containing the carbonaceous material can be installed close to the floorboards 5, so the effects of the carbonaceous material can be felt even more in the indoor space. Moreover, the breathable bags B containing the carbonaceous material and the wire mesh 4b can be easily removed by simply removing the floorboards 5 from the joists 4, which is advantageous for maintenance and renovation. The above is the configuration of the underfloor structure 1 of the building.
[0022] Next, the flow of the carbonaceous material installation method carried out by a worker will be explained with reference to Figure 3. The carbonaceous material installation method involves installing breathable bags B containing carbonaceous material on joists 4 that make up the underfloor structure 1 of a building. Hereinafter, it is assumed that in the underfloor structure 1 of a building, a continuous footing 2 is laid on the ground GL, and a base 3 and joists 4 are assembled on top of the continuous footing 2 in sequence.
[0023] First, support members 4a are attached to both side surfaces of the joists 4 that face each other in the width direction and to the side surface of the base 3 that faces the joists 4 (Step S1). The support members 4a are attached to the side surfaces of the joists 4 and the base 3 so that their longitudinal directions coincide with the longitudinal directions of the joists 4 and the base 3.
[0024] Next, one or more wire meshes 4b are placed on the pair of opposing support members 4a attached in step S1 (step S2). As a result, the pair of support members 4a support both ends of the wire mesh 4b. One wire mesh 4b can be placed on the pair of support members 4a, or multiple wire meshes 4b can be placed side by side.
[0025] Next, a breathable bag B containing carbonaceous material is placed on one or more wire meshes 4b placed in the process of step S2 (step S3). It is preferable to arrange a plurality of bags B containing carbonaceous material side by side on the wire mesh 4b.
[0026] Next, floor boards 5 are attached onto the joists 4, and the breathable bags B containing the carbonaceous material are enclosed in the spaces between the wire mesh 4b and the floor boards 5 (step S4). The above is the procedure for installing charcoal materials.
[0027] As explained above, the method for installing carbonaceous material according to the embodiment includes the steps of attaching support materials 4a to each of the opposing side surfaces of a pair of adjacent joists 4 in the underfloor structure 1 of a building, placing wire mesh 4b on each support material 4a, and placing breathable bags B containing carbonaceous material on the wire mesh 4b. This does not interfere with the work of workers in the underfloor space, and the effect of the carbonaceous material can be felt even more clearly in the indoor space.
[0028] The present invention is not limited to the above-described embodiment, and the following modifications are possible.
[0029] (Variation) In the above embodiment, the floorboards 5 are fixed onto the base 3 and joists 4, but the present invention is not limited to this. For example, a plurality of joists may be fixed parallel to one another on the base 3 and joists 4 so as to extend in a direction perpendicular to the joists 4, and the floorboards 5 may be fixed onto each joist.
[0030] In the above embodiment, the continuous footing 2 is used as the underfloor structure 1 of the building, but the present invention is not limited to this. For example, a mat footing may be used as the underfloor structure 1 of the building.
[0031] In the above embodiment, the support members 4a are attached to the side surfaces of the joists 4, but the present invention is not limited to this. For example, the support members 4a may be attached to the bottom surface of the joists 4 so as to protrude in the width direction (horizontal direction) of the joists 4. In this case, as shown in the cross-sectional view of Figure 4(a), separate support members 4a may protrude from each of the two side surfaces of the joists 4, or as shown in the cross-sectional view of Figure 4(b), the same support member 4a may protrude from each of the two side surfaces of the joists 4.
[0032] In the above embodiment, the support member 4a extends continuously in the longitudinal direction of the joist 4, but the present invention is not limited to this. For example, multiple support members 4a may be attached to the joist 4 at intervals in the longitudinal direction of the support member 4a.
[0033] In the above embodiment, wire mesh 4b is used as the mesh member, but the present invention is not limited to this. For example, a resin trical net may be used as the mesh member. Furthermore, the support member that supports the breathable bag B containing the carbonaceous material is not limited to a mesh member as long as it is breathable, and may be, for example, a metal plate with multiple perforations or a wooden slatted board.
[0034] In the above embodiment, the carbonaceous material is placed on the wire mesh 4b by placing the carbonaceous material in the breathable bag B and then placing the breathable bag B on the wire mesh 4b, but the present invention is not limited to this. For example, the carbonaceous material may be placed in a breathable bucket instead of the breathable bag B. Furthermore, if the carbonaceous material is larger than the mesh openings of the wire mesh 4b, the carbonaceous material may be placed directly on the wire mesh 4b.
[0035] The above-described embodiments are merely examples, and the present invention is not limited to these. Various embodiments are possible within the scope of the invention as set forth in the claims. The components described in the embodiments and modifications can be freely combined. Furthermore, inventions equivalent to the inventions set forth in the claims are also included in the present invention. [Explanation of symbols]
