Description

[Technical field]

[0001] The present invention relates to a siding mounting bracket for mounting adjacent pieces of siding to each other. [Background technology]

[0002] Conventionally, when attaching siding pieces to each other, for example, side by side, hat-shaped siding mounting hardware is used at the joints (joints). Specifically, the convex end of the siding mounting hardware is placed at the joint, and the siding pieces are installed so that the convex end is sandwiched between them. After that, the joints between the siding pieces are filled with caulking material (sealant) so as to fill in the convex end of the siding mounting hardware, and the siding is installed (for example, see FIG. 3 of Patent Document 1).

[0003] [Patent Document 1] JP 2009-57777 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, a cavity is formed inside the siding to reduce its weight, and the open end of this cavity is disposed in the joint. However, in the case of construction using the above-mentioned conventional siding mounting hardware, the open end of the cavity is completely sealed by the caulking material filled in the joints. Therefore, when the siding is repeatedly heated and cooled by sunlight or outside air after construction, the air in the cavity expands and contracts, and pressure is applied from inside the siding to the caulking material filled in the joints, which causes problems such as the caulking material expanding outward or the adhesive between the caulking material and the end face of the siding breaking and peeling off.

[0005] The present invention has been made in consideration of the above points, and aims to provide a siding mounting bracket that can effectively and sustainably prevent defects in the caulking material after installation. [Means for solving the problem]

[0006] (1) A siding mounting bracket that is installed in a joint when multiple sidings having internal cavities are attached adjacent to each other, A convex end portion is disposed in the joint, An air permeable member is provided on the outer surface of the protruding end portion, The air-permeable member is provided at the joint. an inner surface secured to an outer surface of the convex end; The side surface is disposed at a position overlapping at least a portion of the open end of the cavity in the siding; A siding mounting bracket having the caulking material attached to its outer surface.

[0007] In the invention of (1), the siding mounting bracket is installed in the joints when multiple pieces of siding with internal cavities are attached next to each other, and has a convex end portion that is placed in the joint. An air permeable member is provided on the outer surface of the convex end portion. The breathable member is positioned in the joint such that its inner surface is fixed to the outer surface of the convex end, its side surface overlaps at least a portion of the open end of the cavity in the siding, and a caulking material is attached to the outer surface.

[0008] According to the invention of (1), when the sidings are attached to each other so that they are adjacent to each other with a joint therebetween, the convex end of the siding mounting bracket with the breathable member fixed on the outside is arranged along the joint. After that, the joint is filled with a caulking material (sealing material) so as to fill the convex end of the siding mounting bracket and the breathable member. As a result, at least a part of the open end of the cavity in the siding overlaps and contacts the side of the breathable member, and the open end of the cavity is covered by the caulking material together with the outer surface of the breathable member. In this state, the cavities of the sidings adjacent to each other communicate with each other through the breathable member. As a result, even if the air in the cavity of the siding expands or contracts after construction, the expansion or contraction of the air in the cavity is mitigated by the cavities of the sidings communicating with each other through the breathable member. As a result, the pressure from inside the siding on the caulking material filled in the joint is reduced, so that defects such as the adhesion between the caulking material and the end face of the siding being broken and peeling off after construction can be effectively and persistently prevented.

[0009] (2) The siding mounting bracket described in (1) is characterized in that the convex end portion is formed with an air hole that penetrates from the outer surface to the inner surface and overlaps with the breathable member.

[0010] According to the invention of (2), the cavities between the sidings are connected through the breathable material, and the air in the cavities flows in and out of the protruding ends from the breathable material through the through holes. This ensures an escape route for the air in the cavities, further reducing the pressure from inside the siding, making it possible to more effectively prevent problems with the caulking material after construction. Effect of the Invention

[0011] According to this invention, defects in caulking materials after installation can be effectively and sustainably prevented. [Brief description of the drawings]

[0012] [Figure 1]1 is a perspective view showing an example of installation of siding using a siding mounting bracket according to an embodiment of the present invention. FIG. [Diagram 2] 2 is a cross-sectional view showing the mounted state of the siding mounting bracket shown in FIG. 1. [Diagram 3] 2 is a perspective view showing the overall appearance of the siding mounting bracket shown in FIG. 1. [Figure 4] FIG. 4 is a cross-sectional view taken along the line AA in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0014] FIG. 1 is an oblique view showing an example of installation of siding S using a siding mounting bracket 1 according to one embodiment of the present invention, FIG. 2 is a cross-sectional view showing the mounted state of the siding mounting bracket 1, FIG. 3 is an oblique view showing the overall appearance of the siding mounting bracket 1, and FIG. 4 is a cross-sectional view taken along the line AA in FIG. 3.

[0015] As shown in FIG. 1, the siding mounting bracket 1 of this embodiment is attached in advance to a location that will become a joint (seam) G between the siding pieces S, for example, when mounting pieces of siding S adjacent to each other on the left and right.

[0016] As shown in Figure 2, the siding mounting bracket 1 not only serves to serve as a base for the caulking material (sealant) C that is filled into the joints G, but also maintains a constant distance between adjacent pieces of siding S, keeping the joints G straight and of a constant width.

[0017] The siding S is attached to a base material U, such as larch wood, via a ventilation fitting K. A moisture-proof sheet B is provided on the surface of the base material U (not shown in FIG. 1). A plurality of cavities S1 are formed in the siding S so as to be arranged at equal intervals in the vertical direction, and open ends S10 of the cavities S1 are formed on both the left and right end faces of the siding S. In this embodiment, the thickness dimension of the base material U is, for example, about 9 mm, and the thickness dimension of the siding S is, for example, about 15 mm. In FIG. 1 and FIG. 2, the cavities S1 are shown relatively large as an example to facilitate understanding.

[0018] As shown in Figures 3 and 4, the siding mounting bracket 1 generally has a long body made of steel plate commonly known as a hat-type joiner, with a vertical dimension of, for example, about 2m. The siding mounting bracket 1 has a convex end portion 10, a side portion 11, and a mounting surface portion 12 as its main body portion, and has a breathable member 20 as an accessory portion. Note that the dimensions of each portion of the siding mounting bracket 1 described below are examples, and can be any dimensions depending on the thickness of the siding S and the width dimension of the joint G.

[0019] The protruding end 10 is a main body portion that is placed as a base in the area that will become the joint G, and has a width dimension W1 of about 10 mm and a height dimension H of about 18 mm from the mounting surface portion 12 described below. The protruding end 10 is formed with a plurality of ventilation holes 13 that penetrate from the outer surface (front surface) to the inner surface (back surface).

[0020] The ventilation holes 13, while covered with the breathable member 20 described later, serve to allow air to flow in and out of the protruding end portion 10. The ventilation holes 13 are, for example, approximately 10 mm x 4 mm in length and width, and are formed at equal intervals of approximately 20 mm along the longitudinal direction of the protruding end portion 10.

[0021] The side portions 11 are the two sides of the main body that are continuous from both sides of the convex end portion 10 in a bent inward position, and the distance W2 between the ends of the opposing side portions 11 is about 8 mm. A gap is formed between the side portions 11, into which caulking material C and the like cannot penetrate. As shown in FIG. 2, the siding S is attached with both left and right end faces abutting against a part of the side portion 11 (a part close to the convex end portion 10). As a result, even if the siding S is lined up vertically, the end faces are aligned straight, and straight joints G are formed with a constant width.

[0022] The mounting surface portions 12 are portions on both sides of the main body that are continuous with the ends of the side surface portions 11 on both sides in an outwardly bent position, and the distance W3 between the tips of the mounting surface portions 12 on both sides is about 38 mm. The mounting surface portions 12 have screw holes (not shown) formed at equal intervals along the longitudinal direction, and are fixed to the base material U via screws.

[0023] The breathable member 20 is, for example, a porous open-cell synthetic resin foam with air bubbles dispersed in plastic, and is fixed so that its inner surface 21 faces the outer surface (front surface) of the convex end 10 and covers the ventilation hole 13. The breathable member 20 is not limited to an open-cell synthetic resin foam, and any material can be used as long as it is a material that can ensure breathability. The breathable member 20 has a width dimension W1 of about 10 mm, the same as the convex end 10, and a thickness dimension t of about 3 mm. Such a breathable member 20 is capable of allowing air to flow in and out of the inside and outside, and is also excellent in terms of cushioning, heat insulation, and light weight. In addition, by providing the breathable member 20, when the caulking material C is filled in the joint G, it is possible to prevent the caulking material C from directly adhering to the convex end 10 (so-called three-sided adhesion).

[0024] As shown in FIG. 2, the side surface 22 of the breathable member 20 is positioned so as to overlap a part of the opening end S10 of the cavity S1 in the siding S, and the caulking material C is attached to the outer surface 23 of the breathable member 20. That is, when the caulking material C is filled in the joint G, the caulking material C, the breathable member 20, and the protruding end portion 10 (ventilation hole 13) are layered in order from the top in the thickness direction, and air flows in and out from the breathable member 20 to the gap between the side portions 11 through the ventilation hole 13. On the other hand, when viewed in the left-right lateral direction, the opening end S10 of the cavity S1 of the siding S is positioned so as to partially overlap the side surface 22 of the breathable member 20. As a result, the cavities S1 of the siding S on both the left and right sides are communicated through the breathable member 20, and as a result, the air in the cavities S1 on both the left and right sides can flow in and out through the breathable member 20. The open end S10 of the cavity S1 may be entirely overlapped with the side surface 22 of the breathable member 20 and completely closed by the breathable member 20.

[0025] Next, the function and effect of the siding mounting bracket 1 after installation in which the siding S is attached to the base material U and the caulking material C is filled into the joints G will be described mainly with reference to FIG.

[0026] 2, when the caulking material C is filled into the joint G, the joint G is partially blocked by the caulking material C, while at least a portion of the open end S10 is blocked by the breathable member 20. As a result, the cavities S1 in the left and right sidings S communicate with each other through the breathable member 20.

[0027] The cavity S1 also communicates with a gap located inside (on the back side of) the protruding end portion 10 from the inner surface 21 of the air-permeable member 20 through the through-hole 13.

[0028] After such construction, when the siding S is repeatedly heated and cooled by sunlight, outside air, etc., the air in the cavity S1 expands and contracts. However, since the cavities S1 are connected to each other through the breathable member 20, the volume of the cavity becomes larger than in the case of a single siding S, and the expansion and contraction of the air in the cavity S1 is mitigated.

[0029] Furthermore, the air in the cavity S1 flows from the inner surface 23 of the breathable member 20 through the through-holes 13 to the gap inside the protruding end portion, so that an escape route for the air in the cavity S1 is secured.

[0030] As a result, the expansion and contraction of the air in the cavity S1 is mitigated compared to when the siding S is used alone, and the pressure from the cavity S1 inside the siding S on the caulking material C filled in the joints G is weakened.

[0031] Therefore, according to the siding mounting bracket 1 of this embodiment, the pressure from inside the siding S on the caulking material C filled in the joints G after installation is weakened, eliminating the risk of the adhesion between the caulking material C and the end face of the siding S breaking and peeling off, and defects in the caulking material C can be effectively and sustainably prevented.

[0032] In addition, since an escape route for the air in the cavity S1 is secured by the through hole 13, problems with the caulking material C can be more effectively prevented.

[0033] The present invention is not limited to the above embodiment.

[0034] For example, the siding mounting bracket 1 may be used in such a manner that the breathable member 20 is prepared as a separate accessory for the main body portion such as the convex end portion 10, and the inner surface 23 of the breathable member 20 is fixed to the outer surface of the convex end portion 10 and then fitted into the joint G before the caulking material C is filled into the joint G.

[0035] The through-holes 13 do not necessarily have to be provided in the protruding end portion 10 depending on the degree of expansion and contraction of the air in the cavity S1 and the degree of breathability of the breathable member 20. [Explanation of symbols]
