Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a siding board (hereinafter simply referred to as a board) useful for forming horizontal exterior walls of buildings and structures. [Prior art] This type of board that has been used in the past includes Japanese Patent Publication No. 51-29339 and Utility Model Publication No. 51-11882.
No., Jikko No. 54-26649, etc. [Problems to be solved by the invention] However, the above board had various problems. In other words, if rainwater is blown by the wind on the board (closing board), the rainwater will leak to the back side because it is simply a connecting structure between flat plates, corroding the edges and pillars, and causing moisture in the room and closet. There were some drawbacks. In addition, because the length of the sloped part of the lower edge to the rising part of the board is long, it is weak in tensile force and has the disadvantage that only an exterior without joints can be formed. Moreover, although the exterior was originally without joints, due to the skill of the builder, the exterior was made up of joints of varying widths, some without joints, some with joints, and there was a risk of injury from the rising parts during construction. In addition, the board has a complicated side shape, making it difficult and expensive to mold.Furthermore, there are no reinforcing ribs on the flat part, so warping, twisting, etc. appear on the decorative surface, which spoils the aesthetic appearance. It was hot. In addition, since all boards have no backing material and the wall base and surface material are in direct contact, condensation forms on the back of the decorative surface, leading to rust and corrosion of the wall base, and the insulation of the wall itself. In addition to lacking fireproofing, fireproofing, and soundproofing properties, the board itself could not be prevented from deforming, the board itself was easily deformed, and it lacked connection strength. Furthermore, these boards lacked a three-dimensional appearance, had many looseness in joint connections, and had drawbacks such as poor waterproofness and engagement force. [Means for Solving the Problem] In order to eliminate such drawbacks, the present invention forms a decorative groove whose cross section is approximately isosceles trapezoidal in the middle of the decorative surface portion, and also reduces the slope of the male and female connecting portions. The side walls are inclined outward to strengthen the board, reduce the loss of surface material in the width direction, improve economic efficiency and workability, and The present invention proposes a board in which the waterproofness of the connecting portion is improved by forming waterproof ribs that protrude in the opposite direction. [Example] Below, typical examples of the board according to the present invention will be described in detail with reference to the drawings. That is, the first
