Description

[Technical field]

[0001] The present invention relates to exterior materials and buildings. [Background technology]

[0002] In recent years, the use of wood materials in relatively large buildings for the purpose of CO2 fixation has been increasing, and the longer wood materials are used, the greater the effect of CO2. The following Patent Document 1 discloses school timber made from recycled materials. There is also a movement to use wood, which is originally combustible, as structural framework and interior materials by making improvements to make it less flammable.

[0003] [Patent Document 1] JP 2000-345610 A Summary of the Invention [Problem to be solved by the invention]

[0004] There is a demand for wood materials as exterior materials for buildings, but the problem is that the appearance changes in a relatively short period of time in areas that are affected by the outdoor environment. Buildings that use wood materials for exterior materials tend to leave a favorable impression, and because of the high demand, various measures to prevent deterioration have been developed and are commercially available. However, even with these measures, the lifespan is shorter than that of exterior materials made from industrial materials, and maintenance is required every 3 to 5 years to maintain the appearance.

[0005] Therefore, the present invention has been made in consideration of the above circumstances, and provides an exterior material and a building that can maintain the beauty of the exterior material. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention employs the following means. That is, the exterior material according to the present invention is a wooden exterior material that is connected to a structural body, and the outer surface side of the exterior material that faces away from the structural body is removable.

[0007] In the exterior material constructed in this way, the outer surface of the exterior material facing away from the building structure is removable. When the exterior material deteriorates over time, the outer surface is removed to expose the interior of the exterior material as a new outer surface. This allows the aesthetic appearance of the exterior material to be maintained.

[0008] In addition, a building according to the present invention may comprise a structure, the exterior material described above connected to the structure, and a support member fixed to the structure, and the exterior material may be engaged with the support member.

[0009] In a building constructed in this manner, the exterior materials are anchored to the support members fixed to the building structure, and therefore the exterior materials can be easily attached to and detached from the support members.

[0010] In addition, in the building of the present invention, the support member has a locking piece protruding in the left-right direction, and a locking groove recessed in the left-right direction is formed in the middle of the exterior material in the thickness direction, and the locking groove may be engaged with the locking piece.

[0011] In a building constructed in this manner, the locking grooves of the exterior material are locked to the locking pieces of the support member. Therefore, the exterior material can be attached to the support member by inserting the locking pieces of the support member into the locking grooves of the exterior material.

[0012] In the building according to the present invention, a space may be formed between the surface of the exterior material facing the building structure and the building structure.

[0013] In a building constructed in this way, a space is formed between the surface of the exterior material facing the building structure and the building structure, and the space functions as external insulation, thereby improving the thermal insulation properties. Effect of the Invention

[0014] According to the exterior material and building of the present invention, the beauty of the exterior material can be maintained. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] An exterior material and a building according to one embodiment of the present invention will be described with reference to the drawings. The following embodiment shows one aspect of the present invention, does not limit the present invention, and can be modified as desired within the scope of the technical concept of the present invention. In the following drawings, the scale of each structure is different from the actual structure in order to make each structure easier to understand.

[0017] Fig. 1 is a schematic perspective view showing a building according to one embodiment of the present invention. Note that in Fig. 1, the exterior materials 3 on the upper floors are omitted. As shown in Fig. 1, the building 100 has a skeleton 1, a support member 2, and an exterior material 3.

[0018] In the following description, a horizontal direction perpendicular to the vertical direction and along the plate surface of each exterior material 3 will be referred to as a left-right direction.

[0019] The skeleton 1 is composed of members such as pillars and beams. The types of structures constituting the skeleton 1 can be appropriately set to reinforced concrete, wood, etc. The surface of the skeleton 1 facing the outside (outdoors) is referred to as the skeleton outer surface 1a.

[0020] The support member 2 is fixed to the body 1 by a fixing means (not shown). The support member 2 is a member for connecting the exterior material 3 to the body 1. The shape, material, etc. of the support member 2 can be set appropriately.

[0021] FIG. 2 is a horizontal cross-sectional view of the fixing portion of the exterior material 3. As shown in FIG. An example of the support member 2 is shown below. As shown in Fig. 2, the support member 2 is a long member that is long in the vertical direction. The support member 2 is made of steel. The support member 2 has a base 21 that is fixed to the main body 1, and a locking portion 22. The locking portion 22 has an extension piece 23 and a locking piece 24.

[0022] The extension piece 23 extends from approximately the center in the left-right direction of the base 21 toward the outdoor side. The locking piece 24 protrudes on both left and right sides from the outdoor side end of the extension piece 23. The locking piece 24 is formed over approximately the entire length of the support member 2 in the longitudinal direction. A recess 26 that is recessed toward the extension piece 23 side is formed between the left-right end of the base 21 and the locking piece 24.

[0023] The exterior material 3 is made of a wood material. As shown in FIG. 1, the exterior material 3 is a long member that is long in the left-right direction. The exterior materials 3 are arranged adjacent to each other in the vertical direction. For example, the length of the exterior material 3 in the left-right direction is about 1800 mm, the width in the vertical direction is about 120 mm, and the thickness in the depth direction is about 60 mm. The size and shape of the exterior material 3 can be set appropriately.

[0024] FIG. 3 is a perspective view of the exterior material 3. As shown in FIG. As shown in FIG. 3, the exterior material 3 has a main body portion 31 , an inner extending portion 32 , and an outer extending portion 33 .

[0025] The main body 31 is a generally rectangular parallelepiped that is long in the left-right direction. As shown in FIG. 2, the inner extension portion 32 protrudes outward from the left-right end portion of the main body 31 on the framework 1 side. The inner extension portion 32 protrudes toward the adjacent exterior material 3 on the left and right. The outer extension portion 33 protrudes outward from the left-right end portion of the main body 31 on the outdoor side. The outer extension portion 33 protrudes toward the adjacent exterior material 3 on the left and right. The protruding length of the outer extension portion 33 is longer than the protruding length of the inner extension portion 32.

[0026] A locking groove 35 is formed between the inner extension portion 32 and the outer extension portion 33. The locking groove 35 is located at the middle of the exterior material 3 in the plate thickness direction. The locking groove 35 is formed so as to be recessed from the left and right ends of the inner extension portion 32 and the left and right ends of the outer extension portion 33 toward the center in the left and right direction of the exterior material 3. The locking groove 35 of the exterior material 3 is locked to the locking piece 24 of the support member 2. The exterior material 3 may be fixed to the support member 2 by a fixing means (not shown).

[0027] FIG. 4 is a perspective view showing upper end portions 3u of a plurality of exterior materials 3 attached in the vertical direction. As shown in Fig. 4, at upper end portions (such as portion A shown in Fig. 1) 3u of the multiple attached exterior materials 3, a retaining member 4 is fixed to the support member 2. The retaining member 4 has a fixing portion 41 that is fixed with a bolt or the like, and a protruding portion 42 that extends from the fixing portion 41 toward the outdoors.

[0028] The protruding portion 42 is disposed above the upper end portion 3u of the exterior material 3. Even if the exterior material 3 attempts to move upward, the exterior material 3 hits the protruding portion 42 and the upward movement is restricted. In addition, taking into consideration that the exterior material 3 expands in the vertical direction due to aging, it is preferable to provide a gap between the upper end portion 3u of the exterior material 3 and the protruding portion 42.

[0029] FIG. 5 is a perspective view showing lower end portions 3d of a plurality of exterior materials 3 attached in the vertical direction. As shown in Fig. 5, at lower end portions 3d (such as portion B shown in Fig. 1) of the multiple attached exterior materials 3, a load support member 5 is fixed to the support member 2. The load support member 5 has a fixing portion 51 fixed with a bolt or the like, and a load support portion 52 extending from the fixing portion 51 toward the outdoors.

[0030] The load support portion 52 abuts against the lower end portion 3d of the exterior material 3. The load support portion 52 supports the load of a plurality of exterior materials 3 attached vertically.

[0031] 2, a removable portion 37 is formed along an outer surface 3a of the exterior material 3 facing away from the body 1. The removable portion 37 is formed from the outdoor side portion of the main body portion 31 to the outdoor side portion of the outer extension portion 33. The outer surface 3a of the exterior material 3 is treated to prevent deterioration by painting or the like.

[0032] The removable portion 37 is a portion that can be scraped off after the outer surface 3a side of the exterior material 3 deteriorates over time. After the removable portion 37 is scraped off, the newly exposed outer surface is subjected to anti-deterioration treatment. For example, the thickness of the removable portion 37 is about 10 mm. If one cycle is five years and 3 mm of the surface layer is scraped off each time, then if the removable portion 37 is 9 mm, the exterior material 3 can maintain a healthy state for 20 years.

[0033] When scraping off the removable portion 37, it is preferable to first remove the exterior material 3 from the support member 2, scrape off the removable portion 37 using a machine tool such as a planer in a factory, and then perform degradation prevention processing. By performing the work in a factory, it is possible to perform highly accurate dimensional control of the scraped off portion, and also to perform degradation prevention processing under appropriate temperature and humidity control.

[0034] A space S is formed between a surface 3b of the exterior material 3 facing the main body 1 and the outer surface 1a of the main body 1. This makes the space S a space that is open in the vertical direction. Since the space S is not an enclosed space, a pressure difference is unlikely to occur between the inside and outside of the space S, so that it is possible to suppress the application of large wind pressure to the exterior material 3. In addition, even if the exterior material 3 gets wet by rain, it dries easily and is unlikely to rot.

[0035] As shown in Fig. 1, the exterior material 3 may not be attached to the opening W1 of the building 100. Alternatively, the exterior material 3 may be attached with gaps above and below, as in the case of the opening W2, to provide a slit-shaped screen.

[0036] When attaching or detaching the exterior material 3, if one of the left and right sides of the exterior material 3 is tilted upward relative to the horizontal plane (see the arrow in Figure 1), the engagement between the locking piece 24 of the support member 2 and the locking groove 35 of the exterior material 3 will be released, and the exterior material 3 can be moved vertically.

[0037] In the building 100 configured in this manner, the removable portion 37 including the outer surface 3a of the exterior material 3 is removable. When the exterior material 3 deteriorates over time, the removable portion 37 is removed to expose the inside of the exterior material 3 as a new outer surface. Thus, the aesthetic appearance of the exterior material 3 can be maintained.

[0038] Moreover, the exterior material 3 is engaged with the support member 2 fixed to the body 1. Therefore, the exterior material 3 can be easily attached to the support member 2 and can also be easily removed.

[0039] Further, the locking grooves 35 of the exterior material 3 are locked with the locking pieces 24 of the support member 2. Therefore, by inserting the locking pieces 24 of the support member 2 into the locking grooves 35 of the exterior material 3, the exterior material 3 can be attached to the support member 2.

[0040] In addition, a space S is formed between the surface 3b of the exterior material 3 and the body 1. Therefore, the space S functions as external insulation, and the heat insulation property can be improved.

[0041] The shapes and combinations of the components shown in the above-described embodiment are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present invention.

[0042] In the above embodiment, the locking piece 24 is formed over substantially the entire length of the support member 2 in the longitudinal direction, but is not limited to this. A plurality of locking pieces 24 may be formed spaced apart in the vertical direction so that each exterior material 3 can be locked at at least one point.

[0043] The "Sustainable Development Goals (SDGs)" are 17 international goals that were adopted at the United Nations Summit in September 2015. The building 100 according to this embodiment can contribute to achieving one of the 17 SDGs, for example goal 9 "Take urgent action to combat climate change." [Explanation of symbols]
