Description

[Technical Field]

[0001] The present invention relates to an exterior material that is installed on a building wall to form the design of the building's exterior (facade) and to block sunlight. [Background technology]

[0002] Louvers have been known as exterior materials provided in curtain wall units that form the exterior walls of buildings (see Patent Document 1). The curtain wall units are arranged side by side vertically and horizontally to form the exterior walls, and louvers are also arranged side by side horizontally. Each louver blocks sunlight and includes a louver blade and flat brackets joined to both the left and right ends of the louver blade, with the brackets of adjacent louvers arranged facing each other in the left-right direction with a gap between them.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-204175 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the louver described in Patent Document 1, adjacent brackets (end faces of the louvers) are arranged facing each other in the left-right direction with a gap between them, which causes a lack of continuity in the left-right direction, impairing the exterior design and causing light leakage through the gap.In addition, there is a risk of wind passing through the gap (whistle). In Patent Document 1, the louvers are arranged side by side in the left-right direction, but even if exterior materials such as louvers are arranged side by side in any other direction, such as up and down, there is a risk that the external design will be impaired, light will leak, and wind noise will be generated, as described above.

[0005] An object of the present invention is to provide an exterior material that can improve the appearance design, suppress light leakage from gaps between end faces, and suppress the generation of wind noise in the gaps. [Means for solving the problem]

[0006] The exterior cladding material of the present invention is an exterior cladding material that is arranged side by side with its end faces facing each other on a building wall, and is characterized by having a long exterior cladding material main body and a dry gap sealant provided on at least one of both end faces of the exterior cladding material main body. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide an exterior material that can improve the appearance design, suppress light leakage from gaps between end faces, and suppress the generation of wind noise in the gaps. [Brief explanation of the drawings]

[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 4, eaves 10 as an exterior material according to this embodiment are installed on a curtain wall 1, which is a building wall consisting of so-called curtain wall units 2 arranged side by side on the top, bottom, left and right sides, to block sunlight. The curtain wall units 2 are pre-assembled as units and then installed on the building framework. They are configured by arranging panels 4, such as glass panels, within a frame 3 that is framed on all four sides, and multiple eaves 10 are installed side by side on the left and right sides of the curtain wall 1. The curtain wall units 2 constitute a window section and a spandrel section that is arranged below the window section. Note that (A) in FIG. 2 is a plan view showing the area surrounded by the dashed line in FIG. 1 from above, and (B) in FIG. 2 is a cross-sectional view showing the eaves 10 installed on the curtain wall 1 from the side. In the following description, the left-right direction of the canopy 10 is the X-axis direction, the up-down direction of the canopy 10 is the Y-axis direction, and the projection direction (depth direction) of the canopy 10 is the Z-axis direction. The X, Y, and Z-axis directions are perpendicular to each other.

[0010] Multiple eaves 10 are arranged side by side in the X-axis direction in the curtain wall 1. Each of the eaves 10 has a long eaves main body 11 (exterior material main body) extending in the X-axis direction, and a dry gap sealant 21 provided on at least one end face 12 of both end faces 12, 13 of the eaves main body 11. The end faces 12, 13 of the eaves main body 11 are arranged facing each other in the X-axis direction, with multiple eaves main bodies 11 arranged side by side in the X-axis direction. The eaves body 11 is formed into a hollow shape extending in the X-axis direction and is composed of an aluminum extrusion with flat plate-shaped cover members 14 attached to the ends at both ends. This aluminum extrusion is extruded and fitted to brackets 15 attached to the curtain wall 1. The eaves body 11 has an upper plate portion 111 that slopes downward from the indoor side to the outdoor side, a lower plate portion 112 provided below the upper plate portion 111, a tip portion 113 connecting the tips of the upper plate portion 111 and the lower plate portion 112, and a base end portion 114 connecting the base ends of the upper plate portion 111 and the lower plate portion 112, and a fitting claw portion is formed on the base end portion 114 to fit into the bracket 15. A continuous portion 115 connecting the upper plate portion 111 and the lower plate portion 112 is formed in approximately the center of the eaves body 11 in the Z-axis direction. In this embodiment, one gap blocker 21 is provided on the end surface 12 of the cover member 14. This gap blocker 21 blocks the joint between the eaves 10 arranged side by side in the X-axis direction, i.e., the gap between the cover members 14 of the eaves main body 11, and one gap blocker 21 is arranged for each gap. The gap blockers 21 are disposed so as to extend in the Z-axis direction, and are set with a gradient that slopes downward from the indoor side toward the outdoor side.

[0011] The gap sealant 21 comprises an aluminum (metal) holder member 22 provided on one end surface 12 of the eave main body 11 (end surface 12 of the cover member 14), and an elastic dry gasket 31 attached to the holder member 22.

[0012] Holder member 22 extends from the indoor side to the outdoor side along end surface 12, and has a base portion 23 that is positioned approximately in the center of end surface 12 of cover member 14 in the Y-axis direction and screwed to cover member 14, and a pair of side portions 24 that extend in the X-axis direction (the longitudinal direction of eave body 11) from both upper and lower edges of base portion 23 and are bent in directions (the Y-axis direction) such that tip edge portions 25 approach each other, and base portion 23 and pair of side portions 24 form a fitting groove 26 into which a dry gasket 31 is fitted. Fitting groove 26 extends along the longitudinal direction of holder member 22, and an opening 261 of fitting groove 26 is formed between the pair of tip edge portions 25 along the longitudinal direction of holder member 22.

[0013] The dry gasket 31 extends from the indoor side to the outdoor side along the end face 12 and has a base 32 that is fitted along the fitting groove 26, two upper and lower fin portions 33 that extend outward in the X-axis direction from the upper and lower edge portions of the base 32 and are continuous in the longitudinal direction of the dry gasket 31, and a pair of covering portions 35 that extend inward in the X-axis direction from the upper and lower edge portions of the base 32 and are arranged to cover the pair of side portions 24. This dry gasket 31 generally covers the holder member 22 when fitted into the fitting groove 26, and the two upper and lower fin portions 33 are positioned in contact with the end face 13 of another canopy 10 adjacent to the end face 12 and separated by a gap. The tip of the dry gasket 31 is welded, which prevents the tip of the holder member 22 from being exposed.

[0014] The eaves 10 described above are assembled in a factory, and the gap sealant 21 is also screwed to the cover member 14 in the factory. Therefore, simply by lining up multiple eaves 10 on the curtain wall 1 along the X-axis direction, the gaps between the multiple eaves 10 are sealed by the gap sealant 21. Therefore, for example, it is possible to seal the gaps between multiple eaves 10 more easily than if a wet sealant were applied to the gaps between multiple eaves 10 on-site, improving workability. Furthermore, the eaves 10 of this embodiment can suppress light leakage and wind noise from gaps between multiple eaves 10 adjacent in the X-axis direction.

[0015] [Variations] In the above embodiment, the eaves 10 is configured by attaching a gap sealant 21 to an eaves main body 11 made of aluminum extrusion, but this is not limited to this. For example, as in the modified example shown in Figures 5 and 6, an eaves 10B may be configured that includes an eaves main body 11B made of prestressed concrete and two upper and lower gap sealants 21B attached to one end face 12 of the eaves main body 11B in the X-axis direction. The eaves main body 11B is attached to the building wall. The gap closer 21B includes a holder member 22B and a dry gasket 31B. Compared to holder member 22, holder member 22B has base portion 23B that is wider in the Y-axis direction than base portion 23, and leg portions 27B extend inward in the X-axis direction from the upper and lower edges of base portion 23B. Leg portions 27B are embedded in eave main body 11B, and base portion 23B is disposed flush with end surface 12 of eave main body 11B. Other than the above, the configuration of holder member 22B is generally similar to that of holder member 22. In the upper gap closeable body 21B, the dry gasket 31B has one fin portion 33B that extends outward in the X-axis direction from the upper edge of a base portion 32B that is fitted to the holder member 22B, and a covering portion 35B that extends inward in the X-axis direction from the upper edge of the base portion 32B and is arranged to cover the upper side portion 24B of the holder member 22B. The fin portion 33B abuts against the end face 13 of another canopy main body 11B that is adjacent in the X-axis direction, and the covering portion 35B prevents the side portion 24B from being exposed upward. Lower gap blocker 21B has the same configuration as upper gap blocker 21B, but is disposed upside down. Therefore, in lower gap blocker 21B, fin portion 33B is disposed on the lower edge of base portion 32B, and covering portion 35B is disposed below side portion 24B, thereby preventing downward exposure of side portion 24B. The upper gap sealant 21B is arranged along the upper surface of the eave body 11B and has a downward slope as it moves from the indoor side to the outdoor side, and the lower gap sealant 21B is arranged along the Z-axis direction.

[0016] An end continuum 28B that continues the tips of the two upper and lower gap sealants 21B is provided at the tips. End continuum 28B is provided on one end face 12 to connect the tips of dry gaskets 31B, and abuts against the other end face 13 of the other canopy 10B. As a result, the tips of the two upper and lower gap sealants 21B are continuous via end continuum 28B.

[0017] In the above embodiment, the holder members 22, 22B are open on the end surface 13 side of the other canopy 10, 10B adjacent in the X-axis direction, but this is not limited to this. For example, openings may be formed on the upper or lower surface of the holder members 22, 22B, and the dry gaskets 31, 31B may be fitted through these openings. In the above embodiment, one gap blocker 21 is provided on end face 12, and two upper and lower gap blockers 21B are provided on end face 12, but this is not limiting, and three or more gap blockers may be provided on at least one of end faces 12, 13. Furthermore, one gap blocker may be provided on end face 12, and another gap blocker may be provided on end face 13. In the embodiment described above, the tips of the two gap closers 21B are connected by the end continuum 28B, but this is not limiting, and the structure of the end continuum 28B may be omitted, and the tips of the two gap closers 21B may be arranged separately. In this case, a welding process may be performed on the tip of the dry gasket 31B in the gap closer 21B so that the tip of the holder member 22B is not exposed. In the above embodiment, the dry gasket 31 has two fin portions 33, and the dry gasket 31B has one fin portion 33B, but this is not limited thereto and the dry gaskets 31 and 31B may have three or more fin portions. Also, the dry gaskets 31 and 31B have the covering portions 35 and 35B, but if there is no problem even if the holder members 22 and 22B are exposed or if the holder members 22 and 22B are positioned so that they are unlikely to be exposed, the covering portions 35 and 35B may be omitted. In the above embodiment, the eaves 10, 10B are configured with gap sealers 21, 21B comprising the aforementioned holder members 22, 22B and dry gaskets 31, 31B, but this is not limited to this. For example, the gap sealer may be configured by overlapping angle irons provided on the end faces 12, 13 of the eaves main body 11, 11B, or the gap sealer may be configured by attaching a plate body to the end face 12 (13) that sandwiches the dry gasket 31, 31B between the main body 11, 11B. In the above embodiment, the exterior material is the eave 10, 10B that blocks sunlight and has the eave main body 11, 11B made of aluminum extrusion or prestressed concrete, but the exterior material may also be a louver that is made up of one or more louver blades and has a plate-shaped cover member attached to the end (small edge) of the louver blade in the X-axis direction. The louvers may be arranged in a series of multiple louvers in any direction, and may be arranged in a series of multiple louvers in the X-axis direction or in the Y-axis direction, for example. In the above embodiment, the eaves 10, 10B that block sunlight are used as exterior materials, but this is not limited to this. Exterior materials that add expression to the design of the building exterior (facade), for example, exterior materials that emphasize horizontal lines in design, may also be used. In the above embodiment, the curtain wall 1 is a so-called unit type, but it may also be a knock-down type.

[0018] [Summary of the invention] (1) The exterior cladding material of the present invention is an exterior cladding material that is arranged side by side with its end faces facing each other on a building wall, and is characterized by having a long exterior cladding material body and a dry gap sealant provided on at least one of both end faces of the exterior cladding material body. According to the exterior material of the present invention, the aforementioned gap sealant is provided on at least one end face thereof, so that when exterior materials are arranged in a row in the longitudinal direction of a building wall composed of, for example, a curtain wall, the gap between the end faces of the exterior materials can be sealed with the gap sealant, thereby improving the external design by giving multiple exterior materials continuous continuity in the longitudinal direction, suppressing light leakage between the end faces of the exterior materials, and further suppressing the generation of wind noise caused by wind passing through the gaps. The exterior material itself of the aforementioned exterior materials consists of eaves, PC (prestressed concrete) panels, louvers, etc. (2) In the exterior packaging material of the present invention, the gap sealant may include a holder member that is provided on the end face of the exterior packaging material main body and has a fitting groove formed along the end face, and a dry gasket that is fitted along the fitting groove and is arranged so as to be able to abut against an end face of another exterior packaging material adjacent to the end face across a gap. According to this configuration, a holder member is provided on the end surface of the exterior material, and a dry gasket is fitted into the holder member, thereby easily forming a gap sealer. (3) In the exterior material of the present invention, the holder member has a base portion that extends along the end face of the exterior material main body and is attached to the exterior material main body, and a pair of side portions that extend from both side edges of the base portion in the longitudinal direction of the exterior material main body and whose tip edges are bent in directions approaching each other, and the fitting groove may be formed to open along the longitudinal direction of the holder member between the tip edges of the pair of side portions. According to this configuration, the opening of the fitting groove is positioned on the side facing the end face of another exterior material adjacent to the exterior material main body to which the holder member is attached, and therefore, by pushing the dry gasket through this opening towards the exterior material main body when assembling the exterior material alone, it is easier to apply force to push the dry gasket into the fitting groove, compared to when a fitting groove that opens on the top or bottom surface of the holder member is formed, for example, and the dry gasket can be easily fitted into the fitting groove.It also becomes easy to configure a holder member that can be attached to the exterior material main body in the same way even if the upside down is reversed, and workability can be improved. (4) In the exterior packaging material of the present invention, one gap blocker may be provided between adjacent ones of the other exterior packaging materials. With this configuration, it is possible to reduce material costs and construction work compared to, for example, a case where two gap closing bodies are provided. (5) In the exterior packaging material of the present invention, at least two of the gap blockers may be provided between adjacent ones of the other exterior packaging materials. With this configuration, compared to when, for example, one gap sealant is provided, each gap sealant can be positioned closer to the outer edge of the end face of the exterior material main body, which makes it possible to seal the gap between adjacent exterior material main bodies to a greater extent, and also improves the continuity between each adjacent exterior material main body on the left and right, thereby improving the external design. (6) In the exterior packaging material of the present invention, the at least two gap blockers may be provided on one of both end faces of the exterior packaging material body. With this configuration, at least two of the gap sealants are provided on one of the end faces, which makes it possible to improve workability compared to, for example, a case in which exterior materials with gap sealants provided on each of one end face and the other end face of the exterior material main body are arranged side by side. (7) In the exterior packaging material of the present invention, the tips of the at least two gap blockers may be continuous with each other. According to this configuration, the gap between adjacent exterior materials can be sealed more suitably, and the continuity of the adjacent exterior materials can be improved, thereby improving the appearance design. The tips of at least two gap closers may be continuous by welding dry gaskets together, or may be continuous via a separate end continuous member. (8) In the exterior packaging material of the present invention, the dry gasket may have two upper and lower fin portions that are continuous in the longitudinal direction and extend so as to be able to abut against the end faces of the adjacent other exterior packaging materials. With this configuration, compared to a dry gasket that has a single fin portion on the top or bottom, for example, the dry gasket can be fitted into the holder member in the same way even if the upside down is reversed, thereby improving workability. (9) In the exterior packaging material of the present invention, the dry gasket may cover the holder member when fitted into the fitting groove. According to this configuration, the holder member can be prevented from being exposed, and the appearance design can be improved. (10) In the exterior packaging material of the present invention, the exterior packaging material body may be made of an aluminum profile having a cover member attached to a small end thereof, and the holder member may be attached to the cover member. According to this configuration, the gap sealant can be easily provided in the exterior material body made of aluminum extrusion, thereby improving workability. (11) In the exterior exterior material of the present invention, the exterior exterior material body may be made of prestressed concrete, and the holder member may have legs that are embedded in the exterior exterior material body. With this configuration, even if the exterior material body is made of prestressed concrete, by embedding the holder member in the exterior material body, the dry gasket can be easily fitted to the holder member fixed to the exterior material body, thereby improving workability.
