The wall structure and building according to one embodiment of the present invention will be described below with reference to the drawings. In the description of each drawing, the same or similar parts or portions are given the same or similar reference numerals.

First, a wall structure 10 according to one embodiment of the present invention will be outlined with reference to FIG. 1. FIG. 1 is a perspective view showing a part of a building 1 equipped with a wall structure 10 according to one embodiment of the present invention.

As shown in FIG. 1, a building 1 has a wall structure 10. The building 1 may be, for example, an industrialized house with a steel frame structure. An industrialized house is composed of, for example, a lower structure such as a reinforced concrete foundation, and a superstructure having a frame structure made up of frame members such as columns and beams and provided above the lower structure. The lower structure is installed on the ground and supports the superstructure. The frame members that make up the frame structure can be standardized in advance, in which case they are manufactured in advance in a factory and then transported to the construction site and assembled.

The wall structure 10 is composed of multiple wall sections 20. The wall sections 20 are wall panels made of reinforced concrete, such as lightweight aerated concrete (ALC). However, the wall sections 20 are not limited to ALC, and may be wall panels made of any material, such as wooden wall panels.

The wall structure 10 includes a partial wall structure that divides an external floor surface such as a roof or balcony. The partial wall structure that divides the external floor surface is, for example, a waist wall handrail 11, a parapet 12, or a hanging wall 13. In order to improve the design of the building 1, the walls 20 that make up these partial wall structures are provided with a covering material 30 such as a coping or lower coping along at least one of the upper and lower ends of the wall 20. The design of the building 1 is improved by arranging the space between the end face of at least one end of the wall 20 and the covering material 30 so that it is in a straight line with the horizontal decorative groove 21 formed on the other adjacent wall 20.

In this specification, in a building 1 including a wall structure 10, a direction parallel to the height direction of the building 1 is referred to as the "height direction", in the surface of a wall section 20 used in the wall structure 10, a direction perpendicular to the height direction is referred to as the "width direction", and a direction perpendicular to the surface of the wall section 20 is referred to as the "thickness direction". Furthermore, in the thickness direction of the wall structure 10, the outdoor side of the building in a plan view is referred to as the "outdoor side", and conversely, the indoor side of the building in a plan view is referred to as the "indoor side". In addition, the end face of the upper end of the wall section 20 in the height direction is referred to as the "upper end face", and the end face of the lower end of the wall section 20 in the height direction is referred to as the "lower end face". In this specification, the terms "parallel", "orthogonal", and "vertical" are intended to include substantially parallel, orthogonal, and vertical states, respectively.

(First embodiment of wall structure)
The configuration of a wall structure 10A, which is a first embodiment of the wall structure 10 according to the present invention, will be described in detail with reference to Figures 2 and 3. Figure 2 is a front view showing a part of the wall structure 10A from the outdoor side. Figure 3 is a cross-sectional view in the thickness direction of the wall structure 10A shown in Figure 2.

As shown in FIG. 2, the wall structure 10A includes a plurality of wall sections 20, a cover material 30, a horizontal seal section 40, and a vertical seal section 50. In the wall structure 10A, the plurality of wall sections 20 are arranged in a line in the width direction or height direction of the wall structure 10A. In FIG. 2, the boundaries of the plurality of wall sections 20 are indicated by dashed lines. The shape of the wall section 20 is, for example, a substantially rectangular plate shape, but is not limited thereto. As shown by the diagonal shading in FIG. 2, a sealant such as mortar is filled between the wall sections 20 arranged in the width direction or height direction from the viewpoint of design, strength, water-stopping property, etc., to form the horizontal seal section 40 or the vertical seal section 50.

2 shows the first wall 20A, the second wall 20B, and the third wall 20C as the wall sections 20 constituting the wall structure 10A. The first wall 20A is composed of a long wall panel extending from the foundation or beam of the lower floor of the building 1 to the beam of the upper floor. The second wall 20B is adjacent to the first wall 20A in the width direction, and its upper end surface is located between the upper end and the lower end of the first wall 20A in the height direction of the wall structure 10A. In this embodiment, the second wall 20B is a wall panel shorter than the first wall 20A, and is arranged so that its lower end position coincides with that of the first wall 20A. At least a part of the second wall 20B plays the role of a waist wall handrail 11 that partitions the outdoor side of an external floor surface such as a balcony provided on the indoor side of the second wall 20B. The third wall portion 20C is disposed so as to be in contact with the second wall portion 20B from above in the height direction and adjacent to the first wall portion 20A in the width direction from the same direction as the second wall portion 20B. The third wall portion 20C may have an L-shaped cross section perpendicular to the height direction. As a result, the third wall portion 20C covers the protruding corner continuing from the first wall portion 20A to the balcony of the building 1, improving the design of the building. A horizontal seal portion 40 is formed between the second wall portion 20B and the third wall portion 20C. A vertical seal portion 50 is formed between the first wall portion 20A and the second wall portion 20B and the third wall portion 20C. However, the number and arrangement of the walls 20 constituting the wall structure 10A are not limited to the illustrated example and may be determined arbitrarily. In addition, hereinafter, when the first wall portion 20A, the second wall portion 20B, and the third wall portion 20C are not particularly distinguished from each other, they are simply collectively referred to as the walls 20.

The wall 20 has a horizontal decorative groove 21 extending in the width direction of the wall structure 10A. In this embodiment, the wall 20 has a plurality of horizontal decorative grooves 21 arranged in the height direction on the outdoor surface with a predetermined width W1 and a predetermined interval D1. That is, the width perpendicular to the extension direction of the horizontal decorative groove 21 of the wall 20 is W1, and the interval between two adjacent horizontal decorative grooves 21 in the height direction of the wall 20 is D1. In this specification, the width perpendicular to the extension direction of the horizontal decorative groove 21 is also simply referred to as the width of the horizontal decorative groove 21. The predetermined interval D1 is approximately an integer divided by the height (floor height) of one floor of the building 1. With this configuration, the design of the building 1 is improved when multiple wall sections 20 are arranged in the width direction or height direction.

Furthermore, the wall 20 is formed with a vertical decorative groove 22 extending in the height direction of the wall structure 10A. In this embodiment, the wall 20 has a plurality of vertical decorative grooves 22 arranged in the width direction on the outdoor surface with a predetermined width W2 and a predetermined interval D2. That is, the width perpendicular to the extension direction of the vertical decorative groove 22 of the wall 20 is W2, and the interval between two adjacent vertical decorative grooves 22 in the width direction of the wall 20 is D2. In this specification, the width perpendicular to the extension direction of the vertical decorative groove 22 is also simply referred to as the width of the vertical decorative groove 22. The predetermined width W2 may be equal to the predetermined width W1. With this configuration, the design of the building 1 is improved when multiple wall sections 20 are arranged in the width direction or height direction.

In this embodiment, the horizontal decorative grooves 21 and the vertical decorative grooves 22 are formed on the outdoor surface of the wall portion 20. That is, in the width direction of the wall portion 20, the side on which the surface on which the horizontal decorative grooves 21 and the vertical decorative grooves 22 of the wall portion 20 are formed faces is the outdoor side, and the side on which the surface opposite to the surface on which the horizontal decorative grooves 21 and the vertical decorative grooves 22 of the wall portion 20 are formed faces is the indoor side. However, the horizontal decorative grooves 21 and the vertical decorative grooves 22 may be formed on the indoor surface of the wall portion 20. Furthermore, the horizontal decorative grooves 21 and the vertical decorative grooves 22 may be formed on both the outdoor side and the indoor side of the wall portion 20. When the horizontal decorative grooves 21 and the vertical decorative grooves 22 are formed on the indoor surface of the wall portion 20, the "outdoor side" and the "indoor side" are to be read interchangeably in the following description.

A cover material 30 is attached to the second wall portion 20B, which is provided along the upper end of the second wall portion 20B and covers the upper end surface of the second wall portion 20B (in this embodiment, the portion of the upper end surface that constitutes the waist wall handrail 11).

As shown in FIG. 3, the cover material 30 is attached to the second wall portion 20B so as to cover the upper end surface of the second wall portion 20B and the base member 31, waterproof member 32, and sealant 33 provided on the upper end surface of the second wall portion 20B. However, the base member 31 and waterproof member 32 may be omitted.

The base member 31 is a base for fixing the cover material 30 to the second wall portion 20B. In this embodiment, the base member 31 is a long member with an L-shaped cross section in the thickness direction of the wall structure 10A, which has an upper piece that covers the upper end surface of the second wall portion 20B and a side piece that covers the surface on the indoor side. The base member 31 is fixed to the second wall portion 20B, for example, by fastening with bolts.

The waterproof member 32 is configured to cover the base member 31. The waterproof member 32 is a plate-shaped member having waterproof properties, such as a steel plate coated with a waterproof paint. The waterproof member 32 is a long member having an L-shaped cross section in the thickness direction of the wall structure 10A, with an upper piece covering the upper end surface of the base member 31 and a side piece covering the indoor side. The waterproof member 32 has an outdoor side folded piece 32A folded back from the outdoor side end of the upper piece toward the upper end surface of the second wall section 20B, and an indoor side folded piece 32B folded back from the lower end of the side piece in the height direction toward the indoor side surface of the wall section 20. As will be described in detail later, a sealant 33 is filled between the outdoor side folded piece 32A and the indoor side folded piece 32B and the wall section 20.

Furthermore, the outdoor-side folded piece 32A of the waterproofing member 32 may be in contact with the outdoor-side end of the upper piece of the base member 31 from the outdoor side. Similarly, the indoor-side folded piece 32B of the waterproofing member 32 may be in contact with the lower end of the height direction of the side piece of the base member 31 from the lower side in the height direction. As a result, when the sealant 33 is filled, the base member 31 supports the waterproofing member 32 from the outdoor-side folded piece 32A or the indoor-side folded piece 32B, so that the waterproofing member 32 is less likely to move due to the filling pressure of the sealant 33. This makes it easier to fill the sealant 33.

The sealant 33 is a wet sealant such as mortar, but may be any material capable of watertightness. The sealant 33 includes a sealant 33A filled in the gap between the outdoor-side folded piece 32A of the waterproofing member 32 and the surface of the wall section 20, and a sealant 33B filled in the gap between the indoor-side folded piece 32B of the waterproofing member 32 and the surface of the wall section 20. As a result, the sealant 33A seals water from the outdoor side of the wall structure 10A between the waterproofing member 32 and the upper end surface of the second wall section 20B. The sealant 33B seals water from the lower side in the height direction of the wall structure 10A between the waterproofing member 32 and the indoor-side surface of the wall section 20.

The outdoor end of the waterproofing member 32 and the sealing material 33A is located indoors relative to the outdoor end of the upper end face of the second wall portion 20B. That is, the waterproofing member 32 and the sealing material 33A are attached to the second wall portion 20B so that the outdoor surface portion of the upper end face of the second wall portion 20B is exposed. With this configuration, it is possible to position the covering material 30, which covers and decorates the waterproofing member 32 and the sealing material 33A, closer to the indoor side. This reduces the protrusion of the covering material 30 to the outdoor side of the wall structure 10A, improving the design of the wall structure 10A and the design of the building 1.

The cover material 30 covers and decorates the upper end surface of the second wall portion 20B, the base member 31, the waterproof member 32, and the sealant 33. The cover material 30 may be attached to the second wall portion 20B by any method. For example, the cover material 30 may have a bracket on the inside. In such a case, the bracket may be fastened to the base member 31 by a screw or the like that penetrates the waterproof member 32, and fixed to the base member 31. However, if the base member 31 and the waterproof member 32 are omitted, the cover material 30 may be attached directly to the second wall portion 20B.

The covering material 30 is a member having an L-shaped cross section in the thickness direction of the wall structure 10A, including an upper piece 30A of a substantially rectangular plate shape that covers the upper end surface of the second wall portion 20B from above the waterproofing member 32, and a first side piece 30B of a substantially rectangular plate shape that hangs down from the indoor end of the upper piece 30A and covers the waterproofing member 32 from the indoor side. With this configuration, the covering material 30 reduces the visibility from the outside of the upper end surface of the second wall portion 20B, the base member 31, the waterproofing member 32, the sealing material 33, etc., and improves the design of the wall structure 10A. However, the covering material 30 may be of any shape and size, for example, a shape that covers only the upper end surface of the second wall portion 20B, taking into consideration the design of the building 1.

Furthermore, the cover material 30 has a second side piece 30C that hangs down from the outdoor end of the upper piece 30A, and a lower piece 30D that bends from the lower end of the second side piece 30C and extends indoors. The outdoor edge of the cover material 30 (the second side piece 30C in this embodiment) is located at a position approximately equal to the outdoor surface of the second wall section 20B in the thickness direction of the wall structure 10A. That is, in the thickness direction of the wall structure 10, the edge of the cover material 30 on the side facing the surface on which the horizontal decorative groove 21 of the first wall section 20A is formed is located at a position approximately equal to the surface of the second wall section 20B on the side facing the surface on which the horizontal decorative groove 21 of the first wall section 20A is formed. As a result, the cover material 30 does not protrude to the side facing the surface on which the horizontal decorative groove 21 of the first wall section 20A is formed (the outdoor side in this embodiment), making it less noticeable, improving the design of the building 1. In this embodiment, the above-mentioned "side on which the surface of the first wall portion 20A on which the horizontal decorative groove 21 is formed faces" is the outdoor side, but it may also be the indoor side. Furthermore, the "side on which the surface of the first wall portion 20A on which the horizontal decorative groove 21 is formed faces" may be both the outdoor side and the indoor side.

The lower piece 30D of the cover material 30 is located above the upper end surface of the second wall portion 20B. At least a part of the lower piece 30D of the cover material 30 is disposed in a position facing the upper end surface of the second wall portion 20B. As a result, a groove portion 60 is formed between the upper end surface of the second wall portion 20B and the cover material 30. In the groove portion 60, at least a part of the outdoor surface of the seal material 33A is exposed to the groove portion 60 to form the groove bottom of the groove portion 60. The part of the outdoor surface of the seal material 33A that is exposed to the groove portion 60 and forms the groove bottom of the groove portion 60 is also called the exposed surface 33S of the seal material 33A. In this embodiment, the groove portion 60 is surrounded by the lower piece 30D of the cover material 30, the exposed surface 33S of the seal material 33A, and the upper end surface of the second wall portion 20B. In this embodiment, the sealant 33A is filled between the upper end surface of the second wall portion 20B and the cover material 30 in the thickness direction of the wall structure 10A so that the outdoor surface of the sealant 33A contacts the indoor end of the lower piece 30D of the cover material 30. However, the outdoor surface of the sealant 33A does not have to contact the indoor end of the lower piece 30D of the cover material 30. In addition, if the cover material 30 does not have the second side piece 30C and the lower piece 30D, the groove portion 60 may be a portion surrounded by the upper piece 30A of the cover material 30, the exposed surface 33S of the sealant 33A, and the upper end surface of the second wall portion 20B.

Referring again to FIG. 2, the groove portion 60 is arranged so as to be in a straight line with the horizontal decorative groove 21 of the first wall portion 20A. In this embodiment, the groove portion 60 is arranged in a straight line in the width direction with the horizontal decorative groove 21A among the multiple horizontal decorative grooves 21 formed in the first wall portion 20A, sandwiching the horizontal seal portion 40 between the second wall portion 20B and the third wall portion 2C. With this configuration, the harmony between the groove portion 60 and the horizontal decorative groove 21 of the first wall portion 20A is improved. Therefore, the wall structure 10A can improve the design of the building 1.

The width W1' perpendicular to the extension direction of the groove portion 60 is approximately equal to the width W1 perpendicular to the extension direction of the horizontal decorative groove 21 of the first wall portion 20A. In this specification, the width perpendicular to the extension direction of the groove portion 60 is also simply referred to as the width of the groove portion 60. The depth of the groove portion 60 may be the distance from the outdoor end of the groove portion 60 to the indoor end in the width direction of the wall structure 1A. The depth of the horizontal decorative groove 21 may be the distance from the outdoor end of the horizontal decorative groove 21 to the indoor end in the width direction of the wall structure 1A. The depth of the groove portion 60 is approximately equal to the depth of the horizontal decorative groove 21 of the first wall portion 20A. This improves the harmony between the groove portion 60 and the horizontal decorative groove 21 of the first wall portion 20A.

The distance D1' between the upper end of the second wall portion 20B and the topmost horizontal decorative groove 21 is approximately equal to the distance D1 between two adjacent horizontal decorative grooves 21. This improves the harmony between the groove portion 60 and the horizontal decorative grooves 21 of the second wall portion 20B.

The bottom of the groove 60, i.e., the exposed surface 33S of the sealant 33A exposed in the groove 60, is finished in a substantially identical manner to the horizontal decorative groove 21 of the first wall 2A. In this specification, substantially the same preferably means identical. However, substantially the same may also include similarity to the extent that does not impair the design of the building. For example, the exposed surface 33S of the sealant 33A may be spray-painted with a paint that is the same or similar to the horizontal decorative groove 21 of the first wall 20A. This improves the harmony between the groove 60 and the horizontal decorative groove 21 of the first wall 20A.

The depth of the groove portion 60 is approximately equal to the depth of the vertical decorative groove 22 formed in the second wall portion 20B. The depth of the vertical decorative groove 22 may be the distance from the outdoor end to the indoor end of the vertical decorative groove 22 in the width direction of the wall structure 1A. As a result, in the thickness direction of the wall structure 1A, the position where the sealant 33 is filled into the groove portion 60 is aligned with the bottom of the vertical decorative groove 22, so that the sealant 33 fits well and the filling operation and filling amount management of the sealant 33 are made easier. In addition, the harmony between the groove portion 60 and the vertical decorative groove 22 of the second wall portion 20B is improved.

The vertical decorative groove 22 has an opening on the upper end surface of the second wall portion 20B. With this configuration, the second wall portion 20B can allow rainwater that falls into the groove portion 60 to flow downward via the vertical decorative groove 22. As a result, the second wall portion 20B makes it difficult for rainwater containing dust adhering to the upper end surface of the second wall portion 20B to flow onto the outdoor surface of the second wall portion 20B, making the surface less likely to become dirty.

The exposed surface 33S of the sealant 33A exposed in the groove 60 has a finish that is substantially the same as the vertical decorative groove 22 of the second wall 20B. For example, the exposed surface 33S of the sealant 33A may be spray-painted with a paint that is the same as or similar to the vertical decorative groove 22 of the second wall 20B. This improves the harmony between the groove 60 and the vertical decorative groove 22 of the second wall 20B.

The depth of the groove portion 60 is approximately equal to the depth of the vertical seal portion 50. The depth of the vertical seal portion 50 may be the distance from the outdoor end to the indoor end of the vertical seal portion 50 in the width direction of the wall structure 1A. This aligns the positions for filling the sealant in the groove portion 60 and the vertical seal portion 50 in the thickness direction of the wall structure 1A, making it easier to fill the sealant and to manage the amount of filling. In addition, the harmony between the groove portion 60 and the vertical seal portion 50 is improved.

The exposed surface 33S of the sealant 33A exposed in the groove 60 is finished in approximately the same manner as the outdoor surface of the sealant of the vertical seal portion 50. For example, the sealant 33A exposed in the groove 60 and the sealant of the vertical seal portion 50 may be made of the same or similar material. Alternatively, the exposed surface 33S of the sealant 33A exposed in the groove 60 may be spray painted with a paint that is the same or similar to the sealant of the vertical seal portion 50. This improves the harmony between the groove 60 and the vertical seal portion 50.

The depth of the groove 60 is approximately equal to the depth of the horizontal seal portion 40. The depth of the horizontal seal portion 40 may be the distance from the outdoor end to the indoor end of the horizontal seal portion 40 in the width direction of the wall structure 1A. This aligns the positions for filling the sealant in the groove 60 and the horizontal seal portion 40 in the thickness direction of the wall structure 1A, making it easier to fill the sealant and to manage the amount of filling. In addition, the harmony between the groove 60 and the horizontal seal portion 40 is improved.

The exposed surface 33S of the sealant 33A exposed in the groove 60 has a finish that is substantially the same as the outdoor surface of the sealant of the horizontal seal section 40. For example, the sealant 33A exposed in the groove 60 and the sealant of the horizontal seal section 40 may be made of the same or similar material. Alternatively, the exposed surface 33S of the sealant 33A exposed in the groove 60 may be spray painted with a paint that is the same or similar to the sealant of the horizontal seal section 40. This improves the harmony between the groove 60 and the horizontal seal section 40.

(Second embodiment of wall structure)
A configuration of a wall structure 10B, which is a second embodiment of the wall structure 10 according to the present invention, will be described in detail with reference to Fig. 4 and Fig. 5. Fig. 4 is a front view showing a part of the wall structure 10B from the outdoor side. Fig. 5 is a cross-sectional view in the thickness direction of the wall structure 10B shown in Fig. 4.

The wall structure 10B according to the second embodiment differs from the first embodiment in that at least a portion of the second wall portion 20B is a hanging wall 13. Below, the second embodiment will be described, focusing on the differences from the first embodiment. Note that parts having the same configuration as the first embodiment are given the same reference numerals.

As shown in FIG. 4, the wall structure 10B includes a plurality of wall sections 20, a cover material 30, a horizontal seal section 40, and a vertical seal section 50. In the wall structure 10B, the plurality of wall sections 20 are arranged in a line in the width direction or height direction of the wall structure 10B. As shown by the diagonal shading in FIG. 4, a sealing material such as mortar is filled between the wall sections 20 arranged in the width direction or height direction to form the horizontal seal section 40 or the vertical seal section 50.

In FIG. 4, the first wall portion 20A, the second wall portion 20B, and the third wall portion 20C are shown as the wall portions 20 constituting the wall structure 10B. The first wall portion 20A is composed of a long wall panel extending from the foundation or beam of the lower floor of the building 1 to the beam of the upper floor. The second wall portion 20B is adjacent to the first wall portion 20A in the width direction, and its lower end surface is located between the upper end and the lower end of the first wall portion 20A in the height direction of the wall structure 10B. In this embodiment, the second wall portion 20B is a wall panel shorter than the first wall portion 20A, and is arranged so that its upper end position coincides with that of the first wall portion 20A. At least a part of the second wall portion 20B plays the role of a hanging wall 13 that partitions the outdoor side of an external floor surface such as a balcony provided on the indoor side of the second wall portion 20B. The third wall portion 20C is disposed so as to be in contact with the second wall portion 20B from below in the height direction and adjacent to the first wall portion 20A from the same direction as the second wall portion 20B in the width direction. A horizontal seal portion 40 is formed between the second wall portion 20B and the third wall portion 20C. A vertical seal portion 50 is formed between the first wall portion 20A and the second wall portion 20B and the third wall portion 20C.

The wall portion 20 is formed with a plurality of horizontal decorative grooves 21 extending in the width direction of the wall structure 10B. Furthermore, the wall portion 20 is formed with a plurality of vertical decorative grooves 22 extending in the height direction of the wall structure 10B.

A cover material 30 is attached to the second wall portion 20B, which is provided along the lower end of the second wall portion 20B and covers the lower end surface of the second wall portion 20B (in this embodiment, the portion that constitutes the hanging wall 13 of the lower end surface).

As shown in FIG. 5, the cover material 30 is attached to the second wall portion 20B so as to cover the lower end surface of the second wall portion 20B and the base member 31 and the seal material 33 provided on the lower end surface of the second wall portion 20B. However, the base member 31 may be omitted.

The base member 31 is a long member having an L-shaped cross section in the thickness direction of the wall structure 10B, and has a lower piece that covers the lower end surface of the second wall portion 20B and a side piece that covers the surface on the indoor side. The base member 31 is fixed to the second wall portion 20B, for example, by fastening with bolts.

The cover material 30 covers and decorates the lower end surface of the second wall portion 20B, the base member 31, and the seal material 33. The cover material 30 may be attached to the second wall portion 20B by any method. The cover material 30 may be fastened to the base member 31 by screws or the like, for example, and fixed to the base member 31. However, if the base member 31 is omitted, the cover material 30 may be attached directly to the second wall portion 20B.

The cover material 30 has a substantially rectangular plate-shaped lower piece 30E that covers the lower end surface of the second wall portion 20B from below, an upright piece 30F that stands from the outdoor end of the lower piece 30E, and an upper piece 30G that bends from the upper end of the upright piece 30F and extends to the indoor side. The outdoor edge of the cover material 30 (the upright piece 30F in this embodiment) is located at a position approximately equal to the outdoor surface of the second wall portion 20B in the thickness direction of the wall structure 10B. That is, in the thickness direction of the wall structure 10, the edge of the cover material 30 on the side facing the surface on which the horizontal decorative groove 21 of the first wall portion 20A is formed is located at a position approximately equal to the surface of the second wall portion 20B on the side facing the surface on which the horizontal decorative groove 21 of the first wall portion 20A is formed. This makes the cover material 30 less noticeable and does not protrude on the side facing the surface of the first wall portion 20A on which the horizontal decorative grooves 21 are formed (the outdoor side in this embodiment), improving the design of the building 1. Note that the above-mentioned "side facing the surface of the first wall portion 20A on which the horizontal decorative grooves 21 are formed" is the outdoor side in this embodiment, but it may also be the indoor side. Furthermore, the "side facing the surface of the first wall portion 20A on which the horizontal decorative grooves 21 are formed" may be both the outdoor side and the indoor side.

The upper piece 30G of the cover material 30 is located below the lower end surface of the second wall portion 20B. At least a portion of the upper piece 30G of the cover material 30 is disposed so as to face the lower end surface of the second wall portion 20B.

The sealant 33 is filled between the upper piece 30G of the cover material 30 and the lower end surface of the second wall portion 20B. As a result, the sealant 33 seals off water from the outdoor side of the wall structure 10B between the cover material 30 and the lower end surface of the second wall portion 20B.

The outdoor end of the sealant 33 is located indoors relative to the outdoor end of the lower end face of the second wall 20B. That is, the sealant 33 is attached to the second wall 20B so that the outdoor surface portion of the lower end face of the second wall 20B is exposed. As a result, a groove 60 is formed between the lower end face of the second wall 20B and the cover material 30. In the groove 60, at least a portion of the outdoor surface of the sealant 33 is exposed in the groove 60 to form the groove bottom of the groove 60. In this embodiment, the groove 60 is surrounded by the upper piece 30G of the cover material 30, the outer surface of the sealant 33A in the thickness direction, and the upper end face of the second wall 20B.

Referring again to FIG. 4, the groove portion 60 is arranged so as to be in a straight line with the horizontal decorative groove 21 of the first wall portion 20A. In this embodiment, the groove portion 60 is arranged in a straight line in the width direction with the horizontal decorative groove 21A among the multiple horizontal decorative grooves 21 formed in the first wall portion 20A, sandwiching the horizontal seal portion 40 between the second wall portion 20B and the third wall portion 2C. With this configuration, the harmony between the groove portion 60 and the horizontal decorative groove 21 of the first wall portion 20A is improved. Therefore, the wall structure 10B can improve the design of the building 1.
