DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] (Embodiment) 1. Overview FIG. 1 shows a wall structure 100 of this embodiment. This wall structure 100 comprises a structural panel 1, a wall underlay panel 2, and a wall material 3. The structural panel 1 is made of a plate-like member such as plywood, and is fixed to a framework 4 such as a pillar. The wall underlay panel 2 is made of a plate-like member, and is provided on the outside of the structural panel 1. Here, the outside of the structural panel 1 means the direction perpendicular to the main surface of the structural panel 1, and the side opposite the framework 4 as viewed from the structural panel 1. The wall material 3 is a plate-like member, and is provided on the outside of the wall underlay panel 2 (the side opposite the structural panel 1).

[0013] A plurality of spacers 6 are provided between the structural surface material 1 and the wall base surface material 2. The spacers 6 are arranged in a line in the vertical and horizontal directions. The spacers 6 are also arranged at intervals from one another. The wall base surface material 2 is a plate-like member having shape retention properties.

[0014] In the wall structure 100 of this embodiment, the wall base surface material 2 is a plate-like member that has shape retention in a plane, and therefore can stably support the wall material 3 provided on the outside of the wall base surface material 2. For example, when the wall material 3 is fixed by nailing or the like, stress is generated in the wall base surface material 2 in a direction perpendicular to its main surface, but since the wall base surface material 2 has shape retention in a plane, it is unlikely to be damaged by this stress. Therefore, in the wall structure 100 of this embodiment, sufficient fixing strength for the wall material 3 can be obtained.

[0015] Furthermore, in the above-mentioned Patent Document 1, if there is no drainage structure on the underside between the base sheet and the covering sheet, there is a risk that the infiltrating water will not be removed. However, in this embodiment, the fixing strength of the wall material 3 is sufficient, so that the wall material 3 can adequately prevent the infiltration of rainwater, etc.

[0016] 2.Details 1 and 2 show a wall structure 100 of this embodiment. This wall structure 100 includes a framework 4, a structural surface material 1, a wall base surface material 2, and a wall material 3. Note that, although the following describes a case in which the wall structure 100 is an exterior wall structure, the wall structure 100 of this embodiment can be applied not only to exterior wall structures, but also to the structure of an interior wall formed inside a building.

[0017] The skeleton 4 is a structure supporting the entire building, and is, for example, made of a wooden frame. The skeleton 4 includes a plurality of columns 40 and studs 41. The columns 40 and studs 41 are arranged side by side at a predetermined interval in the left-right direction. Here, the left-right direction is a direction perpendicular to the up-down direction in which the columns 40 and studs 41 extend, and is parallel to the main surface of the structural surface material 1. A heat insulating material 42 such as rock wool or glass wool is provided between the adjacent columns 40 and studs 41. An interior material 43 is provided inside the columns 40 and studs 41. The interior material 43 is, for example, a plate-like member such as plywood or gypsum board, and is fixed to the columns 40 and studs 41 with nails, screws, or the like. The inside of the columns 40 and studs 41 is the inward / outward direction perpendicular to the main surface of the structural surface material 1, and is the inward direction (indoor direction) as viewed from the columns 40 and studs 41.

[0018] The structural surface material 1 is a surface material used to construct load-bearing walls, and examples of such materials that can be used include structural plywood, structural OSB (Oriented Strand Board), structural particle board, and structural MDF (Medium Density Fiberboard). The structural surface material 1 is a flat plate-like member whose main surface (surface perpendicular to the thickness direction) is formed flat. The structural surface material 1 is placed on the outside (outdoor side) of the columns 40 and studs 41, and is fixed to the columns 40 and studs 41 with nails, screws, or the like.

[0019] A moisture-permeable waterproof sheet 7 can be provided on the outer surface of the structural facing 1. The moisture-permeable waterproof sheet 7 is a sheet material that has the property of allowing moisture to pass through but not allowing water to pass through. The moisture-permeable waterproof sheet 7 can release moisture inside the house to the outside and prevent moisture from entering the house from the outside. The moisture-permeable waterproof sheet 7 can be provided over the entire outer surface of the structural facing 1.

[0020] A wall base panel 5 is provided on the outside of the structural surface material 1. The wall base panel 5 is composed of a wall base surface material 2 having a plurality of spacers 6 integral therewith. The wall base panel 5 is water resistant. Here, water resistance refers to the property of not causing a significant change in properties such as shape and hardness even when moisture such as rainwater adheres to the panel. The wall base surface material 2 and spacers 6 that constitute the wall base panel 5 are also water resistant.

[0021] The wall base panel 5 can be made of a water-resistant resin molded product, in which case the wall base facing 2 and the spacer 6 are also made of water-resistant resin molded products. An example of a water-resistant resin molded product is a polystyrene molded product. The wall base panel 5 is preferably a resin foam, which makes the wall base panel 5 lighter and easier to install. An example of a resin foam is expanded polystyrene, and in this case, one foamed by the bead method can be used.

[0022] As shown in Figures 3A and 3B, a plurality of spacers 6 are provided on one surface of the wall base surface material 2. The inner surface (the main surface facing inward) of the wall base surface material 2 is formed into a flat surface, and a plurality of spacers 6 are provided so as to protrude inward from this flat inner surface. The plurality of spacers 6 are lined up at approximately equal intervals in the vertical direction. The plurality of spacers 6 are also lined up at approximately equal intervals in the horizontal direction. The spacers 6 have a cross section formed into an approximately trapezoidal shape, and have an outer shape that is smaller at the tip side than at the base side (the wall base surface material 2 side). The spacers 6 are formed into an approximately square shape when viewed inward.

[0023] A plurality of recesses 23 are provided on the outer surface (main surface on the wall material 3 side) of the wall base surface material 2. The plurality of recesses 23 are each formed in a substantially square shape when viewed inward. The plurality of recesses 23 are formed at positions corresponding to the plurality of spacers 6. That is, the recesses 23 provided on the outer surface of the wall base surface material 2 are formed to correspond one-to-one with the spacers 6 provided on the inner surface of the wall base surface material 2. As a result, when the recesses 23 are confirmed on the outer surface of the wall base surface material 2, it is found that the spacers 6 are located at positions corresponding to the recesses 23. Therefore, even if the position of the spacers 6 is not directly confirmed by looking at the inner surface side of the wall base surface material 2, the position of the recesses 23 can be easily grasped by looking at the position of the recesses 23 from the outer surface side of the wall base surface material 2. In other words, the recesses 23 have properties as marks 21 indicating the position of the spacers 6. Therefore, when the wall material 3 is fixed with a fastener 30 such as a nail or a screw, the position of the fastener 30 relative to the spacer 6 can be determined by using the recesses 23 as a guide. Therefore, even if the position of the spacer 6 cannot be seen from the outer surface side of the wall base surface material 2, the fixing device 30 can be hammered in using the recess 23 as a guide, and the fixing device 30 can be easily made to penetrate the spacer 6 or not to penetrate it.

[0024] The recess 23 also serves as a portion for accommodating the spacer 6 when multiple wall base panels 5 are stacked and transported or stored. As shown in FIG. 4, multiple wall base panels 5 are stacked vertically for transport or storage, and are stacked vertically with the inner surface of the wall base surface material 2 facing upward and the outer surface of the wall base surface material 2 facing downward. Therefore, the spacer 6 protrudes upward from the inner surface of the wall base surface material 2, and the recess 23 opens downward on the outer surface of the wall base surface material 2. The vertically adjacent multiple wall base panels 5 are stacked with the spacer 6 of the lower wall base panel 5 inserted into the recess 23 of the upper wall base panel 5. Therefore, the multiple wall base panels 5 can be stacked with a lower height (bulk) than when there is no recess 23.

[0025] The depth dimension of the recess 23 is smaller than the protruding dimension of the spacer 6. The depth dimension of the recess 23 is less than the thickness of the wall base facing material 2, and may be approximately 3 / 4 of the protruding dimension of the spacer 6. This allows the tip portion of the spacer 6 rather than the base portion to be accommodated in the recess 23. It is also preferable that the outer shape of the spacer 6 is approximately the same as the inner shape of the recess 23, so that the spacer 6 can be accommodated in the recess 23 with almost no gaps, and multiple wall base panels 5 can be transported and stored stably.

[0026] The wall underlay panel 5 is disposed on the outside (outdoor side) of the structural surface material 1 and fixed to the structural surface material 1 with fasteners such as nails and screws. At this time, the inner surface (indoor side) of the wall underlay panel 2 is disposed facing the outer surface of the structural surface material 1 and the outer surface of the moisture-permeable waterproof sheet 7 in the outside-inside direction. The spacer 6 is disposed between the inner surface of the wall underlay panel 2 and the outer surface of the structural surface material 1 and the outer surface of the moisture-permeable waterproof sheet 7. The tip surface (inner end) of the spacer 6 is disposed in contact with the outer surface of the moisture-permeable waterproof sheet 7. The spacer 6 forms a space between adjacent spacers 6 as a ventilation layer 8 between the inner surface of the wall underlay panel 2 and the outer surface of the structural surface material 1 and the outer surface of the moisture-permeable waterproof sheet 7. Moisture that passes through the moisture-permeable waterproof sheet 7 from indoors is released to the outdoors through the ventilation layer 8.

[0027] The wall base panel 2 is a plate-like member that forms a base when fixing the wall material 3, and is placed on the outside (outdoor side) of the structural panel 1. The outer surface of the structural panel 1 and the inner surface of the wall base panel 2 face each other in the inward / outward direction with a predetermined gap (the protruding dimension of the spacer 6) between them.

[0028] A plurality of wall materials 3 are provided on the outside of the wall base facing material 2. The wall material 3 is an exterior wall material, and for example, a ceramic siding mainly composed of hardened cement can be used. The wall material 3 can be formed into a substantially rectangular plate shape extending in the left-right direction.

[0029] The multiple wall materials 3 are provided on the outer surface (outer side) of the wall base panel 2 in an armor-plated structure. The armor-plated structure is composed of multiple wall materials 3 arranged in a staggered armor-plated pattern. The multiple wall materials 3 are each fixed to the structural panel 1 with fasteners 30 such as nails or screws. The multiple fasteners 30 are driven into the wall material 3 from the outer surface side, penetrating the wall material 3, the wall base panel 5 and the moisture-permeable waterproof sheet 7, and then driven into the structural panel 1. The multiple fasteners 30 penetrate the wall base panel 5, and thus the wall base panel 2, but some fasteners 30 penetrate the spacer 6, while others do not.

[0030] The multiple wall materials 3 are arranged side by side in the left-right direction and also in the up-down direction. The wall materials 3 adjacent in the up-down direction are offset in the left-right direction, and are arranged in a so-called staggered pattern. In this embodiment, the wall materials 3 adjacent in the up-down direction are offset by half the length in the left-right direction. Furthermore, the lower part of the wall material 3 in the upper row is located outside the upper part of the wall material 3 in the lower row, and the wall materials 3 adjacent in the up-down direction are arranged in a so-called armor-like pattern. Each wall material 3 is arranged on the outer surface of the wall base surface material 2 in an inclined position so that the lower part is located outward.

[0031] The wall structure 100 of this embodiment formed in this manner can stably support the wall material 3 provided on the outside of the wall base surface material 2, because the wall base surface material 2 is a plate-like member having shape retention properties, and further, because the wall material 3 is fixed to the structural surface material 1 by fasteners 30, the fixing strength of the wall material 3 can be sufficiently ensured.

[0032] In addition, in the wall structure 100 of this embodiment, the spacer 6 and the wall base surface material 2 are integrally formed, and thus the construction work can be reduced compared to the conventional method. For example, in the comparative example shown in Figs. 10A and 10B, the wall base panel 5 is not used, and instead, furring strips 51, exterior material base surface material 52, and waterproof sheet 53 are used. That is, a plurality of furring strips 51 are arranged in the left-right direction and fixed to the outer surface of the moisture-permeable waterproof sheet 7 provided on the outer surface of the structural surface material 1, and further, exterior material base surface material 52 is arranged and fixed on the outer side of the plurality of furring strips 51, and the waterproof sheet 53 is provided on the outer surface of the exterior material base surface material 52. In such a comparative example, the construction of the plurality of furring strips 51, exterior material base surface material 52, and waterproof sheet 53 must be performed in sequence, which is time-consuming, but in this embodiment, the construction of the wall structure 100 having the ventilation layer 8 can be formed by simply installing the wall base panel 5, which reduces the construction work and reduces costs. Moreover, since the wall base panel 5 is made of expanded polystyrene, it is lighter than the wooden furring strips 51 and the exterior material base surface material 52, and is easier to install.

[0033] (Modification) The embodiment is merely one of various embodiments of the present invention. The embodiment can be modified in various ways depending on the design and the like as long as the object of the present invention can be achieved.

[0034] In the wall base panel 5, the arrangement and size of the plurality of spacers 6 and the arrangement and size of the plurality of recesses 23 can be changed as appropriate.

[0035] For example, in the wall base panel 5 shown in FIG. 5A and FIG. 5B, a row of spacer groups 61 formed of a plurality of spacers 6 arranged in the vertical direction and a row of spacer groups 61 located adjacent thereto are vertically offset by the dimension of one spacer 6. Therefore, a plurality of half spacers 62 are formed at the upper end and the lower end of the wall base surface material 2. The vertical dimension of the half spacer 62 is formed to be approximately half the vertical dimension of the spacer 6. In addition, a plurality of half spacers 62 are formed in a line along the upper end edge and the lower end edge of the inner surface of the wall base surface material 2. Therefore, the upper end edge and the lower end edge of the inner surface of the wall base surface material 2 are reinforced by the plurality of half spacers 62, making it difficult for damage such as chipping to occur. Note that, even in this modification, the recess 23 is provided on the outer surface of the wall base surface material 2 at a position corresponding to the spacer 6.

[0036] In the wall base panel 5 shown in Figures 6A to 6C and 7A to 7C, a plurality of spacers 6 and a plurality of recesses 23 are provided on the same surface (inner surface) of the wall base surface material 2. As shown in Figure 6A, a plurality of spacers 6 and a plurality of recesses 23 are formed alternately arranged in the vertical direction on the inner surface of the wall base surface material 2. In addition, a plurality of spacers 6 and a plurality of recesses 23 are also formed alternately arranged in the horizontal direction on the inner surface of the wall base surface material 2.

[0037] Meanwhile, a plurality of marks 21 are provided on the outer surface of the wall base facing material 2. The plurality of marks 21 are provided at locations corresponding to the spacers 6, respectively. Therefore, by using the marks 21 as guides to hammer in the fasteners 30, it is possible to easily hammer the fasteners 30 into the spacers 6 or into positions away from the spacers 6 even if the spacers 6 cannot be seen from the outer surface side of the wall base facing material 2. The marks 21 may be formed by printing letters or symbols, or may be formed into a concave shape by molding or the like.

[0038] In such wall foundation panels 5, as shown in FIG. 8, the spacer 6 and the surface on which the recess 23 is formed are stacked facing each other. That is, in the wall foundation panels 5 arranged in the vertical direction, the inner surface of the lower surface of the wall foundation surface material 2 of the upper wall foundation panel 5 faces the inner surface of the upper surface of the wall foundation surface material 2 of the lower wall foundation panel 5, and multiple wall foundation panels 5 are stacked. Then, the recess 23 and the spacer 6 located at the position facing each other in the vertical direction are fitted together. That is, the spacer 6 of the upper wall foundation panel 5 fits into the recess 23 of the lower wall foundation panel 5, and the spacer 6 of the lower wall foundation panel 5 fits into the recess 23 of the upper wall foundation panel 5. In this way, multiple wall foundation panels 5 are stacked and transported or stored. And, in the wall foundation panels 5, the upper and lower surfaces become flat when multiple panels are stacked, making it easy to transport and store.

[0039] In the wall base panel 5 shown in Fig. 9, a plurality of spacers 6 and a plurality of recesses 23 are provided on the same surface (inner surface) of the wall base facing material 2. The spacers 6 and the recesses 23 are formed so as to correspond one-to-one. The spacers 6 and the recesses 23 are also formed so that one of the four corners of the spacer 6 is adjacent to one of the four corners of the recesses 23. Such a wall base panel 5 is overlapped with the surfaces on which the spacers 6 and the recesses 23 are formed facing each other.

[0040] In the embodiment, the wall base surface material 2 (wall base panel 5) with the spacer 6 integrally formed thereon is used, but the present invention is not limited to this, and the spacer 6 and the wall base surface material 2 may be formed separately. In this case, the number of spacers 6 for the wall base surface material 2 and the interval between adjacent spacers 6 can be changed according to the construction site, etc., making construction easier.

[0041] In the embodiment, a ceramic siding is used as the wall material 3, but the present invention is not limited to this, and ceramic slate, metal siding, wood siding, etc. may also be used.

[0042] In the embodiment, the wall material 3 is armored, but the present invention is not limited to this and may have a structure in which the wall materials are butted up and down and against each other.

[0043] (summary) The wall structure 100 according to the first embodiment comprises a structural surface material 1 fixed to a framework 4, a wall base surface material 2 provided on the outside of the structural surface material 1, and a wall material 3 provided on the outside of the wall base surface material 2.

[0045] The second embodiment is the wall structure 100 according to the first embodiment, in which the wall base facing material 2 has a mark 21 at a position corresponding to the spacer 6 on the outer surface.

[0046] According to this embodiment, by using the mark 21 as a guide to drive the fastener 30 into the wall material 3, even if the spacer 6 cannot be seen from the outer surface side of the wall base surface material 2, it is possible to easily drive the fastener 30 into the spacer 6 or into a position away from the spacer 6.

[0047] The third aspect is the wall structure 100 according to the first or second aspect, in which the wall base facing material 2 has a spacer 6 integrally therewith.

[0049] The fourth aspect is a wall structure 100 relating to the third aspect, in which the multiple wall base panel materials 2 have recesses 23 on the surfaces on which the spacers 6 are formed, into which the spacers 6 fit when the surfaces on which the spacers 6 are formed are placed opposite each other and overlap each other.

[0050] According to this embodiment, the wall base surface materials 2 provided with the spacers 6 can be stacked while the spacers 6 are fitted into the recesses 23, and even when stacked, the wall base surface materials 2 provided with the spacers 6 can be transported and stored without becoming bulky.

[0051] A fifth aspect is the wall structure 100 according to the first or second aspect, in which the wall base facing material 2 has water resistance.

[0053] The sixth aspect is the wall structure 100 according to the first or second aspect, in which the multiple wall materials 3 are provided on the outer surface of the wall base facing material 2 in an armor-clad structure.

[0054] According to this embodiment, a wall structure 100 with a highly aesthetic design can be formed, and the multiple wall materials 3 constructed using an armor-clad structure make it difficult for rainwater and other water to reach the wall base surface material 2, improving the waterproofing of the wall structure 100.

[0055] The wall base facing material 2 according to the seventh embodiment is used in the wall structure 100 according to the first or second embodiment, and has a spacer 6 integrally therewith.
