Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to structural hardware for buildings, and in particular to structural materials.
This invention relates to metal fittings that frame and connect braces together with horizontal members and column members.

(Prior art) For the past years, carpenters have used manual techniques to connect convex grooves on vertical columns and concave grooves on horizontal members such as beams to connect frame members and structural members of wooden buildings. A frame construction method has been used in which grooves are inserted and joined, and reinforcing hardware such as L-shaped hardware or box hardware is used. Recently, as three-story wooden buildings are being constructed, not only the strength of the joints but also the speed of work,
For the sake of simplicity, hardware has been proposed that directly joins the joints of structural materials without providing a tenon or the like.

JP-A-56-122449 discloses a method in which a mounting board having a U-shaped cross section is formed into which a vertical member made of a column is inserted and fixed, and a vertical piece is provided that extends perpendicularly from at least one side of the mounting board. , A horizontal material such as a beam material is inserted through the cut groove into this vertical piece, and the vertical material and the horizontal material are connected by supporting the lower surface of the horizontal material with a receiving plate provided at the lower edge of the vertical piece. A connecting fitting has been proposed.

(Problem to be Solved by the Invention) However, with the conventional hardware as described above, since the mounting board covers three sides of the pillar material, it is difficult to attach the wall base plate to the pillar material. Even if the wall is installed, there will be a difference in level and it will be difficult to get a good finish on the wall. Also,
Since the dimensions of the mounting board must be changed according to the cross-sectional dimensions of the pillar, there are a large number of types, and this lacks versatility. Furthermore, the structure does not allow the use of a mounting board when the pipe column is erected on the base or the trunk. Therefore, although it is not explicitly stated in the proposed technology, a structure must be used in which a vertical plate is erected on top of the receiving plate. However, in such a case, there is an inconvenience that pillar members having different heights must be used depending on the presence or absence of the receiving plate. Furthermore, since braces, which are structural members, cannot be attached to such metal fittings, there is a problem in that a separate fitting for braces must be attached.

The present invention has been made in view of these conventional problems, and it is possible to attach and detach plate-like members that connect vertical structural members such as columns and braces using fasteners provided on horizontal structural members that are horizontal members. If the vertical member is a column, the plate-like member will fit into the cut groove provided at the end of the column and be fastened together, and if it is a brace, the horizontal member within the base material of both walls. Place it on the part and fasten and join. Another object of the present invention is to provide a hardware structure in which members and elements constituting the hardware can be added and arranged as necessary so that all the structural members of a wooden building can be joined at any cost.
