Abstract

PROBLEM TO BE SOLVED: To facilitate execution of works for construction boards by furnishing a male joiner member, which has a male part in the form of a short tab to be fitted in a female part and a stationary end in the form of a long tab, and a female joiner member which has a decoration surface and a fit part in approx. a tumbled F-shape. SOLUTION: A male joiner member 3 is formed with a section of approx. H-shape wherein the bottom edge member is extended outward perpendicularly from the stationary end contacting with the substructure 5 and a male part in the form of a short tab is provided at the outer end of the bottom edge member. A female joiner member 2 is formed with a section of approx. tumbled F-shape which is provided with a wide decoration surface facing the outside and wherein female part is composed of this decoration surface and a folded- back edge or an edge member in the form of a short tab. The male joinermember 3 is adhered to a construction board 1, and nail 4 is driven into the stationary end of the male joiner member 3 so that fixation to the substructure 5 is established, followed by insertion of the female part of the female joiner member 2, and thus two hoards 1 are secured to each other. This ensures an enhanced design quality, ad waterproofness of the joint part can be secured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board joiner used for constructing a building board.

[0002]

2. Description of the Related Art Conventionally, when constructing a building board as an exterior wall material for a building, a nail is directly hammered onto the board to fix it to the underlying structure, and then caulking agent is injected into the joints between the boards to ensure waterproofness. Was.

[0003]

However, since the head of the nail is exposed on the surface by performing the brain strike, there is a problem in design such that the appearance is significantly impaired. In addition, even though it is necessary to fix the boards with proper spacing, since there is no positioning mechanism, it is very difficult to perform positioning and fixing to the underlying structure. That is, because it depends on the caulking agent that hits the joint as waterproof as the outer wall,
The waterproofness is greatly affected by the ability of the operator to hit the caulking agent, leaving anxiety about the rain finish, and the caulking agent deteriorates and cracks due to aging. There was also a problem in construction such as doing. Further, if the fitting portion is directly molded from the face material, the number of manufacturing steps is increased and the shape that can be molded is restricted.

[0004]

In order to solve the above-mentioned problems, according to the present invention, a male joiner having a male part and a female part having a female part are provided in contrast to conventional hammering of nails and injection of caulking agent into joints. A board joiner consisting of two members, a side joiner and a side joiner is used. The male joiner has a short tongue portion for fitting with the female portion and a long tongue-shaped fixed end for hitting a nail or a bolt. The female joiner has a substantially inverted F-shaped fitting portion including a decorative surface that also serves as a joint cover and a short tongue side. Both male and female joiners are glued directly to the board. A board joiner with the above features is used. Further, the manufacturing method thereof is easy by roll forming using a thin plate or pultrusion forming using light metal.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing a case where a construction board to which a board joiner according to the present invention is adhered is constructed. First, in order to attach the board 1 to which the male joiners 3 are adhered, nails or bolts are driven into the fixed ends of the male joiners to fix the boards to the base. Next, insert the female part of female joiner 2 to fix the boards together. In FIGS. 2 and 3, A is roll-formed by a thin plate, and B is drawn-formed by a light alloy or resin.

[0006]

When the board joiner according to the present invention is used by directly adhering it to the end of the board, the nail head is completely invisible and the joint is covered, so that the design is remarkably improved. With the fitting portion of the joiner, the spacing between the boards can be easily determined by a simple work of fitting, and the base structure can be securely fixed by nailing the fixed end. The waterproof property of the joint part is ensured by the structure of the fitting part, so that the performance can be surely ensured regardless of who works. In addition, the deterioration of waterproofness due to aging is eliminated. Since the board and the complicated fitting part of the shape are manufactured separately, the molding becomes easier and the flexibility of each shape increases. And the like.
