Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an architectural connection that easily and firmly connects a horizontal member and a vertical member by side-loading a vertical piece and a receiving part for fixing the horizontal member to a mounting board that can be fixed to the vertical member. Regarding metal fittings.

Traditionally, horizontal members such as beams and vertical members such as columns in wooden buildings are:
For example, they have been joined by a so-called tenon joint, in which a vertical member has a mortise hole and a horizontal member has a tenon that can fit into the mortise hole, but such a tenon joint is difficult to process and does not have sufficient connection strength. Furthermore, it sometimes significantly deteriorates the strength of the material.

The purpose of the present invention is to provide a connecting fitting for building constructions that solves these problems, and one embodiment thereof will be described below with reference to the drawings.

In FIGS. 1 and 2, the connecting fitting 1 of the present invention is, for example, a pillar 2.
At the center of one side of the mounting board 3 having a U-shaped cross section into which the vertical member 2 (a) can be inserted, a vertical piece 4 extending vertically and having a cylindrical bulge 4a connected to the tip is applied with a lateral force. The vertical piece 4
A plate-shaped horizontal receiving portion 5 of a sound size that is slightly shorter than the length of the vertical piece 4 is attached to the lower surface, and the mounting board 3 is attached to the mounting board 3 through bolt holes 6 drilled on both opposing sides thereof. After inserting the bolt 7 through the vertical member 2 and fixing it with the nut 8, insert the vertical piece 4 of the connecting fitting 1 into the center of the end face of the horizontal member 9, which is a beam 9a, by 3%, and insert the vertical member 2 from the end face to the material axis. The bulge is formed in the cut groove 12 in which a hollow part 11 consisting of an arcuate groove or the like having a diameter smaller than the width of the split groove 10 is connected to the inner end surface of the split groove 10 which is continuous in the upper and lower directions. The cut groove 1 is fitted into the slot 11 of the section 4af, and is inserted by pushing the horizontal member 9 from above.
A bolt 15 passing through a bolt hole 13 crossing the split groove 10 of No. 2 and a bolt hole 14 of the vertical piece 4 is screwed together with a nut 16.

At this time, the receiving piece 5 places and supports the lower surface of the horizontal member 9, thereby firmly connecting and hanging the vertical member 2 and the horizontal member 9.

Note that the horizontal member 9 is installed with a length t of the bolt head separated from the vertical member.

3 to 6 show other embodiments of the present invention, and the one in FIG. 3 has vertical pieces 4, 4 and receiving parts 5, 5 formed on both sides of the mounting board 3, respectively. The one in Fig. 4 has vertical pieces 4 on one side and the U-shaped bottom of the mounting board 3, the one in Fig. 5 has vertical pieces 4 on each side of the mounting board 3, and the one in Fig. 6 only on the bottom face. A receiving portion 5 is formed with a screw, and each bolt hole 6 is bored on the opposite side surface of the mounting board 3.

Note that, as shown in FIG. 6, the depth dimension of both opposing side surfaces of the mounting board 3 can also be formed short.

As described above, the connecting fitting of the present invention is provided with a vertical cut groove on the end face of the horizontal member, and the verticality of the connecting fitting is inserted into the cut groove and fixed, and the vicinity of the fitting part is received from below by the receiving part. Since the horizontal member is restrained from moving in the horizontal direction by the vertical piece, the vertical force is borne by the receiving piece, and the two are firmly and stably connected.

In addition, compared to the conventional connecting method that connects horizontal and vertical members using dotoku-tenon joints, this method not only improves the connection strength and saves labor in connection work, but also eliminates cross-sectional loss of the joint due to processing of tenons, etc. Installation strength can be increased.

Furthermore, since the mounting board 3 is formed with a U-shaped cross section, vertical members can be fitted into it, simplifying the installation work, and when bolts are fixed by inserting the bolts through the surface on the opposite side, they act as washers, There is no possibility of fitting or deformation of each village due to bolt heads, nuts, etc.

A hollow part such as an arcuate groove is connected to the inner end of the roughly cut groove and engages with the cylindrical bulge at the tip of the vertical piece, improving the strength of horizontally mounting the horizontal member. This facilitates positioning and installation.

The connecting fitting of the present invention can be used not only for wooden buildings but also for steel frame buildings such as lightweight steel structures.
