Description

  The present invention relates to a joint material for forming an outer wall having a ventilation layer and an outer wall structure using the same.

  Conventionally, an outer wall structure as shown in FIG. 8 has been proposed. Reference numeral 50 is a foundation, on which a base 51 is formed, and on the base 51, a plurality of columns 52 and inter-columns 53 are erected. Further, a heat insulating material 54 is disposed between the adjacent columns 52 and the intermediary columns 53, and a moisture-permeable waterproof sheet 55 is provided on the surface side (outdoor side) of the columns 52, the intermediary columns 53, and the heat insulating material 54. . Further, a plurality of horizontal trunk edges 56 that are long in the horizontal direction are arranged in the vertical direction on the surface side (outdoor side) of the moisture-permeable waterproof sheet 55. A plurality of exterior materials 57 such as sidings are attached to the front side (outdoor side) of the horizontal trunk edge 56 side by side. Thus, an outer wall of a house or the like can be formed. In some cases, a vertical trunk edge is used instead of a horizontal trunk edge.

  In such an outer wall, as shown in FIGS. 9 (a) and 9 (b), a joint 58 that is long in the lateral direction is formed between the upper and lower exterior members 57, 57. The material 59 is filled to ensure waterproofness. In this case, the sealing material 59 is applied using the joint material A. That is, the joint material A (Joiner) A has a substantially hat-shaped cross section and is formed in an elongated shape in the lateral direction, and has a U-shaped receiving portion 60 and fixing pieces 61 and 61 extending upward and downward from the receiving portion 60. The fixing piece 61 is fixed to the surface of the horizontal trunk edge 56, and the joint material A is disposed on the surface side of the horizontal trunk edge 56. And by arranging the exterior materials 57 and 57 on the upper side and the lower side of the receiving portion 60 of the joint material A, the lateral direction is long between the upper end surface and the lower end surface of the exterior materials 57 and 57. A joint 58 is formed, and the sealing material 59 is filled over the entire length of the joint 58 on the surface side of the receiving portion 60.

  FIGS. 10A and 10B show the structure of the eaves part.

A gap is provided between the moisture waterproof sheet 55. Further, a sealing material 59 is filled between the lower surface of the eaves ceiling board 68 and the upper end of the exterior material 57, and the sealing material 59 is supported by a backup material 77.

  FIG. 13 shows another conventional outer wall structure. In this conventional example, the exterior member 57 is vertically stretched by a vertically stretched vent fitting fastening method. That is, in the same manner as described above, the structural plywood 81 is provided on the studs 53 erected on the base 51 on the foundation 50, and the ventilation fitting 70 and the ventilation are provided on the outdoor surface of the structural plywood 81 via the moisture-permeable waterproof sheet 55. A metal starter 71 is attached, a side end portion of the exterior material 57 is held on the ventilation metal fitting 70, and a lower end of the exterior material 57 is held by the ventilation metal starter 71. In this case, a space as a ventilation layer 72 is formed between the exterior material 57 and the moisture-permeable waterproof sheet 55 by the ventilation fitting 70 and the ventilation fitting starter 71. 14 (a) and 14 (b) show details of the eaves top portion in the outer wall structure of FIG. In this case, an auxiliary trunk edge 73 is provided between the crosspiece 67 to which the eaves ceiling plate 68 is attached and the moisture-permeable waterproof sheet 55 in order to allow the ventilation layer 72 to communicate with the outside air at the eaves top. A gap is provided between the moisture waterproof sheet 55. FIGS. 15A and 15B show details of an intermediate portion in the outer wall structure of FIG. In this case, in order to allow the ventilation layer 72 to communicate with the top and bottom of the ventilation fitting starter 71, a through-hole 82 penetrating the ventilation fitting starter 71 vertically is formed. Further, a spacer 79 is provided between the exterior material 57 and the moisture-permeable waterproof sheet 55, and a gap is provided between the crosspiece 67 and the moisture-permeable waterproof sheet 55. Further, a sealing material 59 is filled between the upper and lower exterior materials 57, and the sealing material 59 is supported by a hat-type joiner (one side type) 80, and the hat-type joiner 80 is supported by a spacer 79. Yes.

As described above, in the horizontal ventilation metal fitting method and the vertical ventilation metal fitting method, in order to ensure the air permeability of the ventilation layer 72, the auxiliary trunk edge 73, the backup material 77, and the hat are provided in the horizontal joint portion and the eaves top portion. A type joiner 80 is used. However, since it is fastened with the ventilation fitting 70, the auxiliary trunk edge 73 is necessary, the number of parts increases, and since the backup material 77 and the hat-type joiner 80 are used, the construction accuracy varies. In addition, the back-up material 77 and the hat-type joiner 80 may enter the ventilation layer 72, and accurate dimensions may not be ensured, which may require time for construction and increase costs.
