Description

  The present invention relates to an exterior finish material that is disposed on an outer surface of a building to form an exterior finish surface.

Patent Document 1 below discloses an exterior finishing material that takes into account design characteristics such as the continuity and uniformity of the pattern of the exterior wall finishing material. Briefly, in this exterior finish material, a brickwork pattern appears continuously in the vertical and horizontal directions on the surface of the exterior finish material. In this case, in order to provide openings such as windows, continuity of the vertical joint pattern and the horizontal joint pattern that forms a brickwork pattern when the exterior finish material is simply cut and spliced according to the size of the opening. And the unity is lost. In order to avoid this, the unit of the exterior finishing material may be reduced, but in that case, there is a problem that the installation work becomes complicated. Therefore, in this prior art, the exterior finishing material is allocated according to the module of the building, so that the continuity and uniformity of the pattern can be maintained and the mounting work can be performed relatively easily. is there.
JP 2000-145091 A (FIGS. 2 and 5) JP-A-10-273960

  However, according to the above prior art, the vertical joint pattern formed in the seam when the exterior finish materials are arranged in the horizontal direction is different from the original longitudinal joint pattern in the surface of the exterior finish material. Since the seam is very conspicuous, the prior art has room for improvement in this respect.

  In addition, in the sense of making the vertical joint inconspicuous, there is also the prior art disclosed in Patent Document 2, but in this prior art, the pattern of the bottom of the horizontal joint and the surface shape of the fixed seal material of the vertical joint coincide. Therefore, there is a clear difference between the vertical joint where the standard sealing material is installed and the vertical groove as the pattern, and the joint of the exterior finish material (vertical joint as a whole) ) Is a very noticeable pattern.

  Moreover, since it does not make much sense to reduce productivity and on-site workability in a building site in order to solve this problem, it is necessary to consider this point as well.

  In consideration of the above facts, the present invention can improve design performance such as continuity and unity of patterns including joints when exterior finishing materials are continuously arranged in the lateral direction, and can also improve productivity and architecture. The object is to obtain an exterior finishing material that can improve workability on the ground.

  The invention according to claim 1 is an exterior finish material that forms an exterior finish surface by continuously arranging a plate-like exterior finish material body along an outer wall surface of a building, and is arranged in the width direction of the exterior finish material body. Grooves for vertical joints formed on the surface side of the end part and in communication with the vertical joints in pairs with the surface side of the end part in the width direction of the adjacent exterior finish material body in a continuous arrangement state of the exterior finish material Are formed at equal intervals from the center of the vertical joint on the surface side of the exterior finish material main body, and have the same or substantially the same cross-sectional shape as the vertical joint concave groove. A set of long fixed seals that are integrally formed at the bottom of each of the plurality of set pattern grooving grooves and the bottom of each pattern allocating groove and are attached to the vertical joints from the outside of the building through the vertical joint forming groove. A plurality of dummy joints having a surface shape that matches the surface shape of the material; Characterized in that it has.

  According to a second aspect of the present invention, in the exterior finishing material of the first aspect, on the surface side of the exterior finishing material main body, there is another groove for pattern assignment having a groove depth equivalent to the groove for pattern assignment. It is characterized by not being formed.

  The invention according to claim 3 is the exterior finish material according to claim 1 or claim 2, wherein the adjacent groove for pattern assignment is connected to the surface side of the exterior finish material main body and the groove for pattern assignment is connected. A horizontal joint pattern having a groove depth shallower than the groove depth is formed.

  According to a fourth aspect of the present invention, in the exterior finish material according to any one of the first to third aspects, the reference dimension of the opening width of the opening provided in the outer surface of the building is the groove for pattern assignment. The width of the exterior finishing material body is set to an integral multiple of the reference dimension of the opening width of the opening.

  According to this invention of Claim 1, an exterior finishing surface is formed by arrange | positioning a plate-shaped exterior finishing material main body continuously along a building outer wall surface. A groove for forming a vertical joint is formed on the surface side of the end portion in the width direction of the exterior finish material body, and by arranging two exterior finish material bodies adjacent to each other in the lateral direction, The joint groove forming portions are arranged to face each other to form the vertical joint and the vertical joint groove communicated with the vertical joint.

  Here, in the present invention, a plurality of pattern allocating grooves are formed at equal intervals from the center of the vertical joint on the surface side of the exterior finish material main body, and the cross-sectional shape of the pattern allocating grooves is vertical. Since the cross-sectional shape of the joint groove is set to be the same or substantially the same, a large number of grooves with the same appearance (vertical joint grooves and a plurality of pattern assignment grooves) are pin-stripe on the surface side of the exterior finishing material. It will be in an orderly state. Furthermore, in the present invention, a dummy joint having a surface shape that matches the surface shape of a long-sized fixed sealing material attached to the vertical joint from the outside of the building through the vertical joint concave groove at the bottom of each pattern allocating groove. Each part is formed as a single unit, so even if you look at the exterior of the building with the fixed sealant attached to the vertical joint through the groove for the vertical joint, the fixed sealant is completely fused into the pin-stripe pattern. An integrated design is formed and maintained.

  In addition, since the plurality of dummy joint portions are integrally formed when the exterior finish material body is manufactured, a large number of dummy joint portions are prepared separately in advance, and each dummy joint portion is arranged in each groove for allocating patterns on the exterior finish material body. Compared to mounting one by one, the productivity is good and the work efficiency in the building is also very good.

  According to the second aspect of the present invention, there is no other pattern allocating groove having the same groove depth as the pattern allocating groove on the surface side of the exterior finishing material body. No matter where the material is cut in the horizontal direction, the pin-stripe pattern does not collapse. Moreover, the piece which was not used after cutting | disconnection can also be used in another location.

  According to the third aspect of the present invention, on the surface side of the exterior finish material main body, the horizontal joint pattern connecting adjacent pattern allocation concave grooves is formed. The horizontal joint pattern is a concave pattern allocation pattern. Since the groove depth is set to be shallower than the groove depth of the groove, the pattern is not conspicuous. Therefore, the overall appearance of the exterior finish material is unified with a pin-stripe pattern, but an effect of slightly relaxing the impression can be provided. In addition, since the horizontal joint pattern has a groove depth shallower than the groove for allocating the pattern, it is not necessary to align and cut the horizontal joint pattern when the exterior finish material is cut in the horizontal direction.

  According to the fourth aspect of the present invention, since the reference dimension of the opening width of the opening provided on the outer surface of the building is set to an integral multiple of the formation pitch of the groove for pattern assignment, the opening width of the opening is set. In addition, the pitch of the dummy joints does not change even if the exterior finish material is cut. At the same time, since the width direction dimension of the exterior finishing material body is set to an integer multiple of the reference dimension of the opening width of the opening, the pitch of the dummy joints on the outer surface of the building changes because the opening is formed. Nor. Therefore, the exterior finishing material can be used effectively.

  As described above, the exterior finish material according to the present invention described in claim 1 exhibits design performance such as continuity and uniformity of patterns including joints when the exterior finish material is continuously arranged in the lateral direction. In addition, it has an excellent effect that productivity and workability in a building site can be improved.

  The exterior finishing material according to the second aspect of the present invention has an excellent effect that the yield of the exterior finishing material can be improved.

  The exterior finishing material according to the third aspect of the present invention has an excellent effect of providing a richer design in the sense that the impression of the exterior finishing surface can be moderated somewhat while improving the yield of the exterior finishing material. .

  The exterior finishing material according to the present invention described in claim 4 has an excellent effect that the yield of the exterior finishing material can be greatly improved.

The width of the pressing portion 46C substantially coincides with the groove width A (see FIG. 1) of the vertical joint concave groove 40, and both end portions in the width direction of the pressing portion 46C are the bottom surfaces of the pair of vertical joint concave groove forming portions 42. It is intended to be locked to a part 42A. Further, the seal portions 46B formed on both side portions of the support portion 46A are in pressure contact with the opposite end surfaces 34A 'and 38A' of both width direction end portions 34A and 38A in an elastically deformed state. Fine vertical grooves 48 are continuously formed in the width direction on the surface of the pressing portion 46C, and form a pattern of the fixed sealing material 46.

  Further, a plurality of pattern allocating grooves 50 are arranged in parallel to the vertical joints 44 on the surface side of the exterior finish material main body 34. The cross-sectional shape of the pattern assignment concave groove 50 is set to be the same as the cross-sectional shape of the vertical joint concave groove 40. Accordingly, the groove width A ′ (see FIG. 1) at the bottom of the pattern allocation groove 50 is also set to be the same as the groove width A of the vertical joint groove 40. A long dummy joint portion 52 having the same cross-sectional shape as the pressing portion 46C of the fixed sealing material 46 is integrally formed at the bottom of each pattern allocating groove 50.

Is an integral multiple of the formation pitch t.

(Action / Effect)
Next, the operation and effect of this embodiment will be described.

  In the present embodiment, when the two exterior finish materials 28 and 36 are arranged adjacent to each other in the lateral direction, the longitudinal joint recessed groove forming portion 42 at the end 34A in the width direction of one exterior finish material main body 34 and the other exterior finish material main body 34 are arranged. The longitudinal joint 44 and the longitudinal joint groove 40 are formed by facing the longitudinal joint groove forming portion 42 of the end 38 </ b> A in the width direction of the exterior finish material main body 38. A fixed sealing material 46 is inserted from the vertical joint concave groove 40 side and attached to the vertical joint 44.

  Here, in the present embodiment, a plurality of pattern allocating grooves 50 are formed at equal intervals from the center of the vertical joint 44 on the surface side of the exterior finishing material body 34 at a predetermined pitch t, and the vertical joint concave grooves 40 are formed. Since the cross-sectional shape and the cross-sectional shape of the pattern allocating groove 50 are both the same isosceles trapezoidal shape, the exterior finish is required in a state where the required number of exterior finish materials 28 are continuously arranged adjacent to each other in the lateral direction. On the surface side of the material 28, a large number of concave grooves (pattern allocation concave grooves 50 and vertical joint concave grooves 40) having the same appearance are arranged in an orderly manner in a pin stripe shape.

  Furthermore, a dummy joint portion having a surface shape that matches the surface shape of the pressing portion 46C of the long fixed seal material 46 attached to the bottom portion of the vertical joint groove 40 at the bottom portion of each pattern allocating groove 50 52 are integrally formed, and when the external appearance of the unit house 10 is viewed, as shown in FIGS. 2 and 4, the fixed seal material 46 is in a pin-stripe pattern (that is, a plurality of dummy joint portions 52). And united design is formed and maintained.

  Moreover, since the plurality of dummy joint portions 52 are integrally formed by press molding at the time of manufacturing the exterior finish material main body 34, a large number of dummy joint portions are prepared separately in advance, and the pattern assignment of the exterior finish material main body 34 is performed. Compared to the case where the grooves 50 are attached one by one, the productivity is good and the field work in the building is eliminated, so the work efficiency is very good.

  Summarizing the above, according to the exterior finishing materials 28 and 36 according to the present embodiment, when the exterior finishing materials 28 and 36 are continuously arranged in the lateral direction, the continuity and uniformity of the pattern including the seam, etc. Design performance can be improved, and productivity and workability in a building site can be improved.

  Further, since no other pattern allocating groove having the same groove depth as the pattern allocating groove 50 is formed on the surface side of the exterior finishing materials 28 and 36 according to the present embodiment, the exterior finishing material No matter what position 28, 36 is cut in the horizontal direction, the pin-stripe pattern will not collapse. Moreover, the piece which was not used after cutting | disconnection can also be used in another location. Therefore, the yield of the exterior finishing materials 28 and 36 can be improved.

  Furthermore, in this embodiment, since the reference dimension W of the opening width of the opening portion such as the window 32 provided on the wall surface of the unit house 10 is set to an integral multiple of the formation pitch t of the pattern allocating groove 50, the window The pitch t of the dummy joint portions 52 does not change even if the exterior finishing material 28 is cut in the longitudinal direction in accordance with the opening width of the opening portion such as 32. At the same time, the width direction dimension B of the exterior finishing material body 34 disposed adjacent to the left and right is also set to an integral multiple of the reference dimension W of the opening width of the opening of the window 32 or the like. Therefore, the pitch t of the dummy joint portions 52 on the outer side surface of the unit house 10 does not change. That is, the restriction that occurs when a horizontal joint pattern having a groove depth equivalent to the groove 50 for pattern allocation is put in the exterior finish material (that is, when cutting in the horizontal direction, cut according to the horizontal joint pattern. There is no restriction). For these reasons, according to the present embodiment, the yield of the exterior finishing materials 28 and 36 can be greatly improved.

[Supplementary explanation of the embodiment]
In this embodiment mentioned above, although this invention was applied with respect to the unit house 10, not only this but what is necessary is just a building.

  In the present embodiment, the pattern allocating groove 50 and the vertical joint groove 40 are set to have the same cross-sectional shape. However, the present invention is not limited to this, and the vertical joint is considered in consideration of the assembling property of the fixed sealing material 40. The groove width of the concave groove 40 may be set to substantially the same cross-sectional shape, for example, by setting the groove width slightly wider than the groove width of the pattern allocation concave groove 50.

  Furthermore, in the present embodiment, the surface side of the exterior finishing material 28 is configured not to form another pattern allocating groove having the same depth as the pattern allocating groove 50. As long as the configuration does not impair the uniformity, a concave groove for applying a slight change may be provided. For example, as shown by a two-dot chain line in FIG. 3, a horizontal joint pattern 60 having a narrow groove width and a very shallow groove width in the lateral direction is formed on the surface side of the exterior finishing material 28 compared to the groove 50 for pattern assignment. A discontinuous pattern may be added. If it is this level, it will not stand out as a handle. Therefore, the overall beauty of the exterior finishing material 28 is unified with a pin-stripe pattern, but it is possible to give an effect that the impression is slightly softened. Moreover, since the groove depth of the horizontal joint pattern 60 is much shallower than that of the concave groove 50 for pattern allocation, when the exterior finish material 28 is cut in the horizontal direction, the horizontal joint pattern 60 is cut in accordance with the position of the horizontal joint pattern 60. There is no need to do. Accordingly, it is possible to increase the design in the sense that the yield of the exterior finish material 28 can be improved and the impression of the exterior finish surface can be moderated somewhat.

It is a cross-sectional view along the 1-1 line of FIG. 2 which shows the cross-section of the principal part in the exterior finishing material which concerns on this embodiment. It is a front view which shows the state which has arrange | positioned two exterior finishing materials which concern on this embodiment adjacently. It is a front view which shows the exterior finishing material shown by FIG. 2 in a single item state. It is an elevation view which shows the external appearance of the unit house comprised using the exterior finishing material which concerns on this embodiment.
