Description

[Detailed Description of the Invention] This invention relates to a fitting for joining a lintel and a promise that can be easily and reliably joined.

Conventionally, the joining of lintels and lintels in wooden buildings was simply done by nailing nails, L-shaped metal fittings, etc. at the joints, making it difficult to tightly join the two parts and requiring skill.

However, this invention consists of an L-shaped fitting in which a splicing piece that is attached to the side wall of the lintel is connected at right angles to a piercing piece that pierces the side wall of a mortise drilled in the lintel; Since the lintel and the lintel are combined with a wedge fitting that is driven into the side wall of the lintel to form the lintel joint, the lintel and the lintel can be tightly joined easily without requiring any skill, thus solving the problems of the conventional method. That's what I did.

That is, to explain this invention with reference to an embodiment, the central part of a horizontal piece of a metal plate 1 having an angular cross-section is cut out into a substantially V-shape, and piercing blades 2 are formed on both sides to form piercing pieces 3. In addition, an L-shaped metal fitting 5 with a square hole 4 bored in the center of the vertical piece and a metal wedge metal fitting 6 for fitting into the square hole 4 are combined to form a fixed joint metal fitting. .

To use the engagement fitting of the above embodiment, first
The piercing pieces 3 of the slotted metal fitting 5 are driven into the left and right side walls of the mortise hole 8 bored on the upper surface side of the mortise hole 8 and fixed thereto.

Therefore, the length of the slot 8 is the length of the tenon protruding from the lower end surface of the slot 9 plus the thickness of two plates of the L-shaped fitting 5. .

Next, the lower end of the wedge 9 is fitted between the vertical pieces of the wedge-shaped fittings 5, 5, and a tenon (not shown) protruding from the lower end surface is fitted into the slot 8, and then the wedge fitting 6 is fitted. is driven through the square hole 4 into the side wall of the hole 9.

The wedge metal fitting 6 is driven in such a way that its beveled edge 6a comes into sliding contact with the upper edge 4a of the square hole 4.As the wedge metal fitting 6 is driven in, the lintel 7 is pulled upward via the L-shaped metal fitting 5. , lintel 7 and promise 9 are tightly joined.

That is, according to this invention, an L-shaped metal fitting is formed by connecting a piercing piece for piercing the side wall of a mortise drilled in the lintel with a fitting piece for attaching it to the side wall of the lintel at right angles. , and a wedge metal fitting for driving into the lintel through the square hole of the splicing piece, and the lintel and the lintel can be easily and tightly joined together.
