Description

[Detailed Description of the Invention] The present invention relates to an improvement of a fastening fitting for connecting a column and a beam.

The inventor of this case proposed this type of metal fitting in the application of Utility Model Application No. 1972-01972, but in this proposed device, the metal fittings are attached to both the column and the beam, and these are connected with bolts, so the column side Two types of metal fittings are required: and one on the beam side. Additionally, since the outer peripheries of the columns and beams were wrapped with metal fittings, it became extremely difficult to install the post-furlough rim, mortar base, control panels, etc.

The present invention is a column-to-beam fastening fitting that eliminates these drawbacks and is constructed as follows. That is, a bottom plate is fixed to the bottom surface of a cylindrical body having a U-shaped cross section, and the bottom plate has both front and rear edges and a rear edge protruding outward from the cylindrical body, and
A notch is provided by cutting out the front ends of both front and rear edges, a stop plate having an L-shaped cross section is attached to the top surface of the cylinder, and the rising part of the stop plate is located directly above the rear edge of the notch of the bottom plate, This is a column-to-beam fastening fitting in which the surface facing the open surface of the cylindrical body is the mounting surface, and through-holes for connecting bolts are drilled in this mounting surface.

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a metal cylinder having a U-shaped cross section, and a bottom plate 2 is fixed to the bottom surface of the cylinder. The bottom plate 2 has both front and rear edges and a rear edge protruding outward from the cylindrical body 1, and a notch 3 is provided by cutting out the front ends of both the front and rear edges. A stop plate 4 having an L-shaped cross section is attached to the upper surface of the cylinder 1, and the raised part 41 of the stop plate 4 is located directly above the rear edge of the notch 3 of the bottom plate 2, with the front part being positioned from the line connecting the two. , the insertion part 5 into the column A. The surface of the cylindrical body 1 facing the open surface 6 is defined as a mounting surface 7, and a plurality of through holes 8 for connecting bolts for fixing the cylindrical body 1 to the pillar A are bored in this mounting surface 7. Note that one of the through holes 8 is a through hole through which a long connecting bolt for fastening the beam B to the column A is passed. 9 is a through hole through which a bracing bolt for fixing the brace C is passed, and 10 is a through hole through which a bolt for fixing the tip of the beam B to the cylindrical body 1 is passed. Next, we will explain how to use this metal fitting. First, as a preparation, a shallow mounting hole a is made on the side of the column A where the beam B is to be attached, into which the insertion part 5 of the cylinder 1 is fitted, and a connecting bolt hole that fixes the cylinder 1 to the column A is passed through. Through horizontal hole B and through horizontal hole C through which the long connecting bolt connecting beam B to column A is passed.
Open the. At the tip of the beam B, there is a front plate 11 of the cylindrical body 1.
and vertical slits d, d into which the rear plate 12 is inserted.
Make a pair of pillars in front and behind, and connect beam B to column A on the top of beam B.
A horizontal hole e is provided through which a long connecting bolt to be fastened is passed, and a groove f is provided for operating a nut screwed into the tip of the connecting bolt. Further, in the front and rear direction near the tip of the beam B, a front and rear hole g is made through which a bracing bolt tow is passed.

When the above preparations are completed, fit the cylinder 1 into the mounting hole a provided in the column A, and connect it to the through hole 8 of the cylinder 1 and the column A.
Column A
Fixed to. Next, drop the tip of the beam B from above the cylinder 1, and insert the front plate 11 of the cylinder 1 into the slits b, b.
and the rear plate 12 is inserted and supported by the bottom plate 2.
After passing the long connecting bolt through the through-hole C of column A, the through-hole 8 of cylinder body 1, and the side hole e of beam B, screw the nut to the tip through groove f, and attach beam B to column A. conclude. When bracing is required, one end of the bracing C is fixed and attached to a bracing bolt that passes through the front and rear holes g and the through hole 9 of the cylindrical body 1.

In addition, when installing beam B on the opposite side,
By using long connecting bolts that extend to the opposite side of the beam B that was just installed, beam B can be installed on the opposite side using the same method as beam B.

Since the fastener of this invention is constructed as explained above, unlike the one proposed in Utility Application No. 51-09728, it is possible to easily and reliably connect a column and a beam with one metal fitting, and the metal fitting can be connected to a column and a beam. Since it goes inside the beam and is not exposed to the outside, it has the effect that the work of attaching the frame and mortar base to these columns and beams after the fact can be done as easily as when no fasteners are used. be.
