Description

  The present invention is a joint member used as a connecting member for a siding plate formed on the back surface of a joint portion formed when an exterior material is formed.

  In order to enhance waterproofness, a slat plate is formed on the back surface of the joint of the vertical joint portion of the exterior material. Therefore, it is desirable to form the siding board continuously from the base to the eaves. However, it is general that the siding board has a length that can be carried by an operator in consideration of workability, transportability, and workability. Therefore, as a method of connecting the plate members in the vertical direction, a joint member for connection is formed between the laying boards, and the waterproofness of the connection portion is ensured by overlapping the upper and lower sides. (For example, refer to Patent Document 1).

JP-A-57-194548

  In Patent Document 1, a water receiving joint piece is formed on the upper portion of the protruding corner joiner, and a lower portion of the protruding corner joiner is overlapped on the upper portion of the water receiving joint piece, so that a gap is not generated at the connecting portion between the protruding corner joiners. It is. However, the connection between the upper and lower sides is not reliable, and there is a risk of water leakage due to a gap.

In order to solve such drawbacks, the present invention has a short shape from a rising portion that projects the substantially central portion of a vertical flat plate material to the outdoor side, and a connecting portion that is composed of an upper connecting piece and a lower connecting piece on both upper and lower ends. The lower connecting piece includes a lower cover portion that protrudes to the outdoor side, a lower fixing portion that protrudes from the lower end on the indoor side of the lower cover portion in the left-right direction, and both ends of the lower fixing portion to the outdoor side. The upper connecting piece is formed from a lower tongue piece that is folded and protruded, and the upper connecting piece includes an upper cover portion that protrudes to the outdoor side, an upper fixing portion that protrudes from the lower end on the indoor side of the upper cover portion, and both ends of the upper fixing portion. The joint member formed from the upper tongue piece which turned up and protruded the part to the outdoor side, and the fitting groove formed from the upper tongue piece is provided.

  According to the joint member according to the present invention, (1) notching is not required when connecting the siding plates. (2) Workability is improved and work efficiency is improved. (3) The waterproofness of the upper and lower connecting portions of the siding board can be improved. (4) Integration with the siding plate is strengthened because of the fitting structure, not just the overlapping structure. There are features and effects.

FIG.

  As shown in FIGS. 1 and 2, the joint member A is formed in a short shape from a rising portion 1 projecting from a substantially central portion of a vertical flat plate material to the outdoor side and connecting portions 2 at both left and right end portions. These are formed on the vertical joints of the slats B formed in the vertical joint portions M.

The rising portion 1 includes a lower cover portion 1a, an upper cover portion 1b, and a concave portion 1c, and the connecting portion 2 is formed of a lower connecting piece 2a, an upper connecting piece 2b, and a step piece 2c. It is a part which superposes on the upper and lower ends of the eye plate B and enhances waterproofness.

  The lower connecting piece 2a includes a lower cover portion 1a formed from the lower side surfaces 3, 4 and the lower surface 5, a lower fixing portion 6 projecting from the lower end of the lower side surfaces 3, 4 in the left-right direction, and both end portions of the lower fixing portion 6. Is formed from a lower tongue piece 7 that is folded back and protrudes to the outdoor side.

    The upper connecting piece 2b includes an upper cover portion 1b formed from the upper side surfaces 9 and 10 and the upper surface 11, an upper fixing portion 8 projecting from the lower end of the upper side surfaces 9 and 10 in the left-right direction, and both end portions of the upper fixing portion 8. Is formed from an upper tongue piece 12 which is folded back and protrudes to the outdoor side, and a fitting groove 13 formed from the upper tongue piece 12.

  The level difference piece 2c is a part formed between the lower connection piece 2a and the upper connection piece 2b via the level difference 14, and is a part formed as a connection part of the lining plate B described later.

  As shown in FIG. 4, the lower connecting piece 2 a covers the rising portion 1 of the joint member A on the rising portion 18 of the lower mat plate B, and is joined to the engaging groove 20 at the upper end portion of the lower mat plate B.
