Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a siding board (hereinafter simply referred to as a board) useful for forming internal and external walls of buildings and structures. [Prior art] This type of board that has been used in the past includes Tokoku No. 51-29339, Utility Model No. 51-11882,
There is Jikko No. 54-26649. however,
There were various problems with the above board. 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 lower edge up to the rising part of the sloped part of the board is long, it is weak against tensile force.
The disadvantage was that only an exterior without joints could 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. Furthermore, the board has a complicated side shape, making it difficult to mold and expensive. [Purpose of the invention] In order to eliminate the above-mentioned drawbacks, the present invention forms a male connecting portion on one end edge of the decorative surface and a female connecting portion on the other edge, and also connects the inclined piece of the male connecting portion with the female connecting portion. The heights of the side walls of the mold connecting part are approximately the same, so that when the wall is formed, the decorative surface of the board is flat, and a groove is provided in the middle of the insertion edge of the male mold connecting part parallel to the longitudinal direction of the board. At the same time, a reinforcing rib is provided at the tip to prevent capillary action and return rain at the connection part of the board.Furthermore, an engaging protrusion is provided in the fitting groove of the female connection part, so that when the boards are connected, there is a difference. The reinforcing ribs and engaging protrusions on the edges improve the engagement force and waterproofness, and the board can be easily installed by one worker without requiring any skill, both horizontally and vertically. We are proposing a board that can be used for both tension and tension. [Structure of the invention] Representative embodiments of the board according to the invention will be described in detail below with reference to the drawings. That is, FIG. 1 is a perspective view showing the above-mentioned board A, and includes, for example, a surface-treated steel sheet, a steel sheet plated with a zinc-nickel alloy, a steel sheet plated with an aluminum-zinc alloy (product name: Gulfuan, Galvalume Steel Sheet, Super Zinc), and an aluminum sheet. , a metal plate (including flat plate and embossed plate) made of one type of aluminum alloy plate, copper plate, clad steel plate, vibration damping steel plate, etc., or a surface formed from a synthetic resin plate by one type of roll, press, extrusion molding, etc. It is formed into a sanderch structure from a material 1 , a core material 20 filled on the back surface of the surface material 1 , and a back material 21 covering the back surface of the core material 20.
