Description

[Technical field]

[0001] The present invention relates to a siding trim member and a siding structure around a sash. [Background technology]

[0002] Patent Document 1 describes a trim structure for an exterior material in which a trim edge is attached to the upper end of the exterior material (siding) under a window that faces the window sill (sash). The trim edge in this trim structure has a trim base portion and a trim cover portion that can be attached to the trim base portion. The trim base portion is integrally formed with a rear vertical piece that is disposed behind the exterior material, a forward-projecting horizontal piece that projects forward from the upper end of the rear vertical piece, an engagement portion that is provided at the tip of the forward-projecting horizontal piece and is disposed spaced apart from the upper end of the exterior material, and a protrusion that projects from the rear vertical piece above the forward-projecting horizontal piece and has a tip that can abut against the lower surface of the window sill. The trim cover part is integrally formed of a front vertical piece arranged on the front surface of the exterior material, a rear-projecting horizontal piece projecting rearward from the upper end of the front vertical piece, and an engaged part provided at the tip of the rear-projecting horizontal piece and hooked onto the engaging part of the trim base part, and also has a drip edge part projecting from the lower end side of the front vertical piece over its entire width toward the front of the exterior material and with its projecting tip part hanging down. The trim base part is attached to the base material behind the exterior material, and after the exterior material is installed, the trim cover part is attached to the trim base part, so that the trim edge is attached to the underside of the window frame.

[0003] Patent Document 2 describes a sealless decorative component consisting of a sash section and a cover section arranged in the gap between the sash section and an exterior wall material (siding) arranged around the sash section. The cover section of this sealless decorative component is provided with first and second locking sections, and the sash section is provided with first and second locking receiving sections. The first locking section and the first locking receiving section, and the second locking section and the second locking receiving section are locked together, whereby the gap between the sash section and the exterior wall material is sealed by the sealless decorative component.

[0004] [Patent Document 1] JP 2009-209617 A [Patent Document 2] Utility Model Registration No. 3137757 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the trim described in Patent Document 1 is attached to the lower side of the window sill, not around the upper or side window sill. In recent years, siding is often used that is pre-cut in a factory rather than at the construction site. When using pre-cut siding, for example, a relatively large gap may occur between the window sash and the siding due to dimensional errors at the site. In this case, the trim described in Patent Document 1 cannot be installed between the left and right and upper parts of the sash and the siding, so it cannot prevent water such as rainwater from entering the base of the siding through the gap that occurs in that part. Even if the trim described in Patent Document 1 can be installed between the left and right and upper parts of the sash and the siding, and the entrance part of the gap between the siding and the trim cover part is covered with a caulking material (sealing material, water-stopping material) to prevent the intrusion of rainwater, etc., there is a problem that the caulking material is directly visible to the user, which impairs the appearance.

[0006] In addition, even in the case of the sealless decorative material described in Patent Document 2, when the gap between the siding and the sash is large, even if the entrance of the gap between the back surface of the cover part and the exterior wall material is covered with a sealant to make it waterproof, the sealant (caulking material) is still directly visible to the user. This causes a problem that the appearance is marred and the function as a decorative material cannot be fulfilled.

[0007] Therefore, an object of the present invention is to provide a siding trim member and trim structure that can prevent the infiltration of water such as rainwater through the gap between the siding and the trim cover without compromising the appearance. [Means for solving the problem]

[0008] The siding trim member of the present invention is a sash It is used by attaching it to the corner of the frame and the siding base material. The siding trim member includes a mounting base portion for mounting to the base material of the siding, and a trim cover portion that can cover the end of the siding by mounting to the mounting base portion. The mounting base portion is formed by bending a steel plate, and includes a mounting plate portion for mounting to the base material, and a mounting cover portion for mounting from the mounting plate portion. Outdoor The siding has an engagement plate portion extending toward the side, and the edge cover portion is formed by bending a steel plate, and the edge cover portion is formed by bending a steel plate.

Effect of the Invention

[0010] According to the siding trim member of the present invention, even if the size of the gap between the sash and the siding varies, for example, when using precut siding, the caulking material can be stored in the caulking material storage section, so that it is possible to prevent water such as rainwater from entering through the entrance part of the gap between the siding and the trim cover plate, and it is applicable to siding around any frame on the top, bottom, left, or right of the sash. In addition, since the caulking material can be stored on the back side of the trim cover plate of the trim cover section, the caulking material is difficult to see directly from the outside no matter where it is placed around the sash. As a result, it is possible to prevent water such as rainwater from entering through the gap between the siding and the trim cover plate without impairing the appearance. In addition, it is possible to attach the trim cover section to the mounting base section after attaching the siding to the base material not only below the sash but also around the sash, improving workability. According to the siding trim structure of the present invention, even if there is variation in the size of the gap between the sash and the siding, for example, when using precut siding, the caulking material is provided in the space surrounded by the trim cover plate, the spacer plate, and the outer surface of the siding, so that it is possible to suppress the infiltration of water such as rainwater from the entrance of the gap between the siding and the trim cover plate. In addition, since the caulking material can be provided on the back side of the trim cover plate, the caulking material is difficult to see directly from the outside no matter where it is placed around the sash. As a result, it is possible to suppress the infiltration of water such as rainwater from the gap between the siding and the trim cover plate without impairing the appearance. In addition, it is possible to attach the trim cover to the mounting base after attaching the siding to the base material not only below the sash but also around the sash, improving workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, a siding trim structure employing a sash-around siding trim member according to one embodiment of the present invention will be described with reference to Figs. 1 to 3.

[0013] As shown in FIG. 1, the trim structure 100 in this embodiment is a trim structure of the siding 2 around the sash 1, including the sash 1, the siding 2 around the sash 1, the base material 3, the trim member 10 of the siding 2, and the caulking material 40. The caulking material 40 is accommodated in a caulking material accommodation section 50, which is defined by the trim member 10 and the siding 2 and will be described later. In FIG. 1, the vertical direction and the horizontal inside-outside direction perpendicular to the vertical direction (the left-right direction in the figure, which is the stacking direction in which the siding 2 and the base material 3 are arranged) are shown, with the outside of the siding 2 (the right side in FIG. 1: the upper side) as the outdoor side, and the inside of the siding 2 (the left side in FIG. 1: the lower side) as the indoor side. Note that FIG. 2 and FIG. 3 are also shown by appropriately reflecting the vertical direction and the inside-outside direction shown in FIG. 1.

[0014] The base material 3 in this embodiment includes a heat insulating material 4 arranged between pillars and studs (not shown), a moisture permeable waterproof sheet 5 arranged on the outer surface of the heat insulating material 4, and furring strips 6 arranged on the outer surface of the moisture permeable waterproof sheet 5, but may be any base material for attaching the siding 2. The base material 3 may also include pillars and studs.

[0015] In this embodiment, the parting member 10 is disposed below the sash 1. The parting member 10 is formed long along the extension direction of the sash 1. More specifically, the parting member 10 in this embodiment extends in a direction perpendicular to the paper surface in FIG. 1. As shown in FIG. 1, the parting member 10 has an attachment base portion 20 and a parting cover portion 30 that can cover the end of the siding 2 by being attached to the attachment base portion 20.

[0016] The mounting base portion 20 is formed by bending a flat steel plate as shown in FIG. 2. The mounting base portion 20 has a mounting plate portion 21 and an engagement plate portion 22, which extend in the vertical direction and are used for mounting to the base material 3 as shown in FIG. 1. The mounting plate portion 21 is a vertical plate-like member extending in the vertical direction. The engagement plate portion 22 has a horizontal plate portion 22a and a folded portion 22b as shown in FIG. 2. The horizontal plate portion 22a is formed by folding the steel plate so that it extends horizontally from the upper end of the mounting plate portion 21 to the outside. The folded portion 22b is formed by folding back the horizontal plate portion 22a from the outer end to the inner end in a U-shape. That is, the folded portion 22b is formed by hemming the tip of the horizontal plate portion 22a. The mounting base portion 21 is long in the vertical direction of the paper surface in FIG. 2, but in the present invention, a plurality of short ones may be attached and used. Also, the mounting plate portion 21 may be attached onto the furring strip 6.

[0017] The parting cover portion 30 is also formed by bending a single flat steel plate, as shown in Fig. 3. The parting cover portion 30 has a cover plate portion 31 and an engaged plate portion 32. The cover plate portion 31 has a parting cover plate portion 33 for covering the outer surface (outside) 2a of the upper end portion of the siding 2, as shown in Fig. 1, and a spacer plate portion 37 for separating the parting plate portion 33 from the outer surface 2a of the siding 2.

[0018] The parting cover plate portion 33 has a vertical plate portion 35a extending downward from the outer end of the engaged plate portion 32, and a folded portion 35b. The folded portion 35b is configured by folding back the vertical plate portion 35a from the lower end to the upper end in a U-shape. The upper end of the folded portion 35b is located halfway up and down the vertical plate portion 35a, in this case, approximately in the center. As shown in FIG. 1, the part of the parting cover plate portion 33 from the center to the lower end in the vertical direction constitutes a distant portion 36 including the end farthest from the sash 1.

[0019] The engaged plate portion 32 includes a first horizontal plate portion 32a extending inward from the upper end of the trim cover plate portion 33 to cover the upper end surface 2b (side side) of the siding 2, a second horizontal plate portion 32b folded back in a U-shape from the inner end of the first horizontal plate portion 32a toward the outer end, a third horizontal plate portion 32c folded back in a U-shape from the outer end of the second horizontal plate portion 32c toward the inner end, and a folded back portion 32d. The tip (inner end) of the third horizontal plate portion 32c is disposed in the middle of the second horizontal plate portion 32b in the inward / outward direction, here, slightly toward the outer end from the center. A recess 32e into which the engaging plate portion 22 can be inserted is formed between the second horizontal plate portion 32b and the third horizontal plate portion 32c. The folded back portion 32d is folded back in a U-shape from the inner end of the third horizontal plate portion 32c toward the outer end. That is, the folded portion 32d is also formed by hemming the tip of the third horizontal plate portion 32c. The folded portion 32d is folded back so as to be disposed within the recess 32e. The folded portion 32d is also folded back so that its tip is located at approximately the center in the inward and outward directions of the third horizontal plate portion 32c. As a result, when the parting cover portion 30 is attached to the mounting base portion 20, the engaging plate portion 22 is inserted into the recess 32e, so that the tip of the folded portion 22b of the engaging plate portion 22 and the tip of the folded portion 32d of the engaged portion plate portion 32 face each other.

[0020] As shown in FIG. 3, the spacer plate portion 37 is provided so as to extend inward from the back side of the vertical plate portion (partition cover plate portion) 35a. More specifically, the spacer plate portion 37 extends horizontally from the upper end of the folded portion 35b toward the inside to form the separated portion 36 of the parting cover plate portion 33. That is, the spacer plate portion 37 is disposed at a predetermined distance downward from the engaged plate portion 32. By forming such a spacer plate portion 37, as shown in FIG. 1, by attaching the parting cover portion 30 to the mounting base portion 20, it is possible to separate the parting cover plate portion 33 and the outer surface 2a of the siding 2 by a predetermined distance, and a pocket (a caulking material storage portion 50 described later) capable of storing the caulking material 40 can be provided on the back side (inside) of the parting cover plate portion 33. In addition, the spacer plate portion 37 is formed to a length that allows its tip to approach or come into contact with the outer surface 2a of the siding 2 when the parting cover portion 30 is attached to the mounting base portion 20.

[0021] In this way, the trim cover plate portion 33 and the spacer plate portion 37 are arranged so as to define a caulking material storage portion 50 capable of storing caulking material 40 in the space surrounded by the outer surface 2a of the siding 2 when the trim member 10 is attached to the base material 3, as shown in Figure 1.

[0022] Next, the situation when the trim member 10 is attached around the sash 1 will be described below with reference to FIG. 1. First, the mounting base portion 20 is fixed to the underlayment 3 below the sash 1 before the siding 2 is fixed. At this time, the mounting plate portion 21 of the mounting base portion 20 is arranged on the surface of the moisture-permeable waterproof sheet 5 in a state of being erected in the vertical direction, the engagement plate portion 22 is brought close to the underside of the sash 1, and the mounting plate portion 21 is fixed to the underlayment 3 with a screw (not shown) or the like. At this time, a gap 7 is provided between the engagement plate portion 22 of the mounting base portion 20 and the sash 1, into which the first horizontal plate portion 32a and the second horizontal plate portion 32b of the trim cover portion 30 can be inserted. As a modified example, in order to more easily form the gap 7, a protrusion portion 21a may be provided in which the mounting plate portion 21 of the mounting base portion 320 extends upward from the intersection point with the engagement plate portion 22 (the corner portion connecting the two) as shown in FIG. 7(a). In this case, an appropriate gap 7 can be easily formed by abutting the protrusion 21a against the lower end of the sash 1 and fixing the mounting base part 320 to the base material 3. Also, the gap 7 can be easily formed by sandwiching a plate of an appropriate thickness between the engagement plate part 22 and the sash 1 to fix the mounting base part 20 to the base material 3 and then removing the plate.

[0023] Next, the precut siding 2 is fixed to the furring strip 6 using fasteners, screws (not shown), etc. At this time, a gap 8 is formed between the upper end of the siding 2 and the sash 1. The siding 2 in this embodiment is precut in advance at a factory, and there is no need to cut it at the construction site, improving work efficiency. In addition, by using the precut siding 2, it is difficult to fine-tune the vertical height of the gap 8, but the gap 8 is covered by the edge cover part 30, so the appearance is not impaired. In this embodiment, the folded part 22b of the engagement plate part 22 of the mounting base part 20 is located in the gap 8 part. As a result, even if the width dimension of the gap 7 varies when the mounting base part 20 is attached to the base material 3, the folded part 22a of the engagement plate part 22 is visible even after the siding 2 is attached, and the subsequent installation work of the edge cover part 30 can be easily performed.

[0024] Next, the trim cover part 30 is attached to the mounting base part 20. At this time, while aligning the engaged plate part 32 of the trim cover part 30 with the sash 1, the first horizontal plate part 32a and the second horizontal plate part 32b of the trim cover part 30 are inserted into the gap 7, and the engaging plate part 22 is inserted into the recess 32e of the engaged plate part 32. As a result, the trim cover part 30 is attached to the mounting base part 20 in a state in which the tip of the folded part 22b of the engaging plate part 22 and the tip of the folded part 32d of the engaged plate part 32 face each other. Therefore, even if the trim cover part 30 attached to the mounting base part 20 is pulled to the outdoor side, the tip of the folded part 22b and the tip of the folded part 32d are engaged in a butted state, so that the trim cover part 30 is less likely to fall off the mounting base part 20. Furthermore, the engaged plate portion 32 of the edge cover portion 30 comes into contact with the lower surface of the sash 1, and the edge cover portion 30 is stably disposed. In this manner, the upper end portion of the siding 2 is covered by the edge cover portion 30.

[0025] After this, the caulking material 40 is accommodated in the caulking material accommodation section 50 surrounded by the separated portion 36 of the trim cover plate section 33, the spacer plate section 37, and the outer surface 2a of the siding 2. By attaching the trim cover section 30 to the mounting base section 20 after applying a predetermined amount of the caulking material 40 to the outer surface 2a of the end of the siding 2, the caulking material 40 can be provided on the back side of the trim cover plate section 33 without the caulking material 40 protruding from between the separated portion 36 (the trim cover plate section 33) and the siding 2. This makes it possible to prevent water such as rainwater from penetrating into the base material 3 side through the gap between the trim cover section 30 (the trim member 10) and the siding 2. In this way, the trim structure 100 is constructed. After the trim member 10 is installed, triangular caulking 41 can be applied to the corner formed by the vertical portion 35 and the underside of the sash 1 to prevent water such as rainwater from entering between the sash 1 and the trim member 10.

[0026] As described above, according to the trim member 10 and trim structure 100 of this embodiment, even if the size of the gap 8 between the sash 1 and the siding 2 varies when, for example, a precut siding 2 is used, the caulking material 40 can be accommodated in the caulking material accommodation portion 50, so that the infiltration of water such as rainwater from the inlet portion of the gap between the siding 2 and the trim cover portion 30 can be suppressed, and therefore the caulking material can be applied to any frame on the top, bottom, left, or right of the sash 1. In addition, since the caulking material 40 can be accommodated on the back side of the trim cover plate portion 33 of the trim cover portion 30, the caulking material 40 is difficult to be seen directly from the outside no matter where it is placed around the sash 1. As a result, the infiltration of water such as rainwater from the gap between the siding 2 and the trim cover portion 30 can be suppressed without impairing the appearance. In addition, it becomes possible to attach the trim cover portion 30 to the mounting base portion 20 after the siding 2 is attached to the base material 3 below the sash 1, improving workability.

[0027] In the above embodiment, the trim member 10 is disposed below the sash 1, but it may be disposed on the left, right, and upper sides of the sash 1 in the same manner as in the above embodiment to suppress the intrusion of water such as rainwater through the gap between the trim member 10 and the siding. When arranging the trim member 10 on the left and right sides of the sash 1, the trim member 10 shown in FIG. 1 may be rotated 90° around a rotation axis along the inside-outside direction. Also, to arrange the trim member 10 above the sash 1, the trim member 10 shown in FIG. 1 may be rotated 180° around a rotation axis along the inside-outside direction. Even in these cases, the same effect as in the above embodiment can be obtained. Furthermore, in the above embodiment, the furring strips 6 are horizontal furring strips, but they may of course be vertical furring strips, and the trim member of the present invention can be preferably applied to furring strips in any direction. Therefore, according to the trim member 10 and the trim structure 100, the same effect as in the above embodiment can be obtained not only below the sash 1 but also around the sash 1.

[0028] 4 to 6, a parting member 210 may be used in which the length in the inward and outward directions in Fig. 4 of the engaging plate portion 222 of the mounting base portion 220 is shorter than the engaging plate portion 22 described above, and the length in the inward and outward directions of the second horizontal plate portion 232b of the engaged plate portion 232 of the parting cover portion 230 is shorter than the second horizontal plate portion 32b described above. In the parting member 210 of this modification, parts having the same configuration as the parting member 10 described above are indicated by the same reference numerals, and description thereof will be omitted.

[0029] As shown in Figures 4 and 5, the engaging plate portion 222 of the trim member 210 in this modified example has a horizontal plate portion 222a that is shorter in the inward and outward directions than the horizontal plate portion 22a described above. The inward and outward length of the horizontal plate portion 222a in this modified example is shorter than the distance between the moisture permeable waterproof sheet 5 of the base material 3 and the siding 2. In other words, it is shorter than the thickness of the furring strip 6. This makes it possible to reduce the difficulty of engaging the engaged plate portion 232 of the trim cover portion 230 with the engaging plate portion 222 of the mounting base portion 220, which may occur when the upper end portion of the siding 2, etc., accidentally comes into contact with the engaging plate portion 222, changing the extension direction of the engaging plate portion 222 or deforming the engaging plate portion 222, when the siding 2 is attached to the furring strip.

[0030] As shown in Figs. 4 and 6, the trim cover portion 230 of the trim member 210 in this modified example has a second horizontal plate portion 232b that is shorter in the inward and outward direction than the second horizontal plate portion 32b described above. The inward and outward length of the second horizontal plate portion 232b in this modified example is shorter than the distance between the moisture-permeable waterproof sheet 5 of the base material 3 and the siding 2, and slightly longer than the horizontal plate portion 222a. This trim member 210 can also be installed around the sash 1 in the same manner as the trim member 10 described above, and the trim structure 200 shown in Fig. 4 is configured. The trim member 210 according to this modified example and the trim structure 200 using this trim member can also obtain the same effect in the same configuration as described above.

[0031] Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible as long as they are within the scope of the claims. For example, in the above embodiment and modified example, the engaging plate portion 22, 222 of the mounting base portion 20, 220 is a horizontal plate-like member, and the engaged plate portion 32, 232 of the parting cover portion 30, 230 has a recess 32e into which the engaging plate portion 22, 222 is inserted, but these may be configured in reverse. In other words, the engaged plate portion 32, 232 of the parting cover portion 30, 230 may be a horizontal plate-like member, and the engaging plate portion 22, 222 of the mounting base portion 20, 220 may be configured to have a recess 32e into which the horizontal plate-like member of the engaged plate portion 32, 232 is inserted. Even with such a modified parting member, it is possible to attach the parting cover portion to the mounting base portion as in the above embodiment and modified example, and the same effect can be obtained in a similar configuration. In addition, when attaching the mounting base portion to the base material 3, the concave engaging plate portion can be abutted against the sash 1 without considering the gap with the sash 1, and when engaging the engaged plate portion of the trim cover portion with the concave engaging plate portion of the mounting base portion, the engaged plate portion can be easily inserted into the concave engaging plate portion along the sash 1 to attach the trim cover portion.

[0032] In the above-mentioned embodiment and modified example, the spacer plate portion 37 extends horizontally, and the caulking material storage portion 50 is configured in the U-shaped portion formed by the separated portion 36 of the parting cover plate portion 33, the spacer plate portion 37, and the outer surface 2a of the siding 2. However, as shown in FIG. 7(b), the spacer plate portion 337 may have an inclined surface extending obliquely upward from the tip (lower end) of the vertical plate portion 35a of the parting cover portion 330. By inclining the spacer plate portion 337, even if the distance between the vertical plate portion 35a (parting cover plate portion 333) of the mounting base portion and the siding 2 is slightly different when the parting cover portion 330 is attached to the mounting base portion, the inclination angle of the spacer plate portion 337 can be changed to absorb it. Also, the tip (end on the siding 2 side) of the spacer plate portion 37 may be inclined so as to be located above the base end. In this case, the folded portion 35b forming the separated portion 36 may not be formed, and the spacer plate portion may be inclined obliquely upward from the lower end of the separated portion 36 (the lower end of the vertical plate portion 35a) toward the siding 2. In this way, a caulking material storage portion may be formed within the triangular portion formed by the spacer plate portion and the outer surface 2a of the siding 2. In these cases, the same effect as described above can be obtained. [Explanation of symbols]
