Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal joint for a building which is interposed between a structural member such as a pillar or a trunk and a transverse member such as a beam, and is used for joining these members to each other.

[0002]

2. Description of the Related Art Abutment against a structural material such as a pillar or a body gap and tightening on the structural material to engage the slit on a surface of a substrate with a slit provided at a joint end portion of a horizontal member such as a beam There is a structure in which the base ends of the joining plates that are assembled with the frame are welded together (see
-20503 publication).

[0003]

This type of building joint metal is one in which a board is fastened to a structural member by bolts and nuts, and then a horizontal member is assembled to the joint plate. When the bolt is fastened to the structural material, the metalwork itself has a certain weight, so the fastening work is complicated. Further, the load applied from above to the horizontal member may concentrate on the welded portion between the surface of the substrate and the base end of the bonding plate, and may be separated from each other. A supporting plate for receiving the joint plate is provided to reinforce the welded part. However, the conventional example is
Due to the existence of the support plate, for example, when joining a beam having a width higher than the body difference to the body difference, in order to make the upper surfaces coincide with each other, a notch for engaging the support plate at the lower part on the beam side must be provided. There is complexity in joining work such as not being possible.

The present invention pays attention to the drawbacks of the conventional example, and can carry out the joining work efficiently, has a load bearing property, and can be applied to any joined material such as a body difference or a beam. It was created for the purpose of providing.

[0005]

[Means for Solving the Problems] The surface of a substrate that abuts against a structural member such as a pillar or a body difference and is fastened to the structural member is engaged with a slit groove provided at a joint end of a horizontal member such as a beam. In the metal joint for building, in which the base ends of the joint plates to be assembled together with the horizontal member are welded, the base end of the joint plate is projected through the through hole provided in the substrate, and further provided in the structural material. The engaging portion that engages with the receiving hole is penetrated to project on the back surface of the substrate.

[0008]

[First Embodiment] FIG. 1 is a perspective view, FIG. 2 is a front view, FIG. 3 is an exploded perspective view, FIG. 4 is a vertical sectional view in a used state, and FIG. 5 is a horizontal sectional view in a used state.

In the first embodiment shown in these drawings, a vertical hole 10a and a horizontal hole 10b are provided above and below the substrate 1, and the vertical hole 10a is arranged at the center along the vertical direction of the substrate 1. And a slightly inverted T-shaped through hole 10 which is symmetrical with respect to the left and right is provided, and an engaging portion piece 11 projecting from a base end portion 2'of the joining plate 2 is provided in a vertical hole portion 10a of the through hole 10 of the substrate 1. Engage and penetrate from the front surface 1a side, and the rear surface side 1 of the substrate 1 in the lateral hole portion 10b of the through hole 10.
From the side b, engage the reinforcing portion piece 12 having the same shape as the lateral hole portion 10b, and weld these, that is, the surface 1a of the substrate 1, the substrate portion 2'of the joining plate 2 and the base end portion of the reinforcing portion piece 12 to each other. However, the joint portions 11 and the reinforcing portion pieces 12 whose free ends coincide with each other and are integral with each other are provided on the back surface 1b of the substrate 1 so as to project in a substantially inverted T shape.

Therefore, the through hole 17 corresponding to the insertion hole 5 provided in the substrate 1 and the receiving hole having the contour shape formed by the engaging portion piece 11 and the reinforcing portion piece 12 projecting on the back surface 1b side of the substrate 1 are formed. 13 is provided in advance in the structural material 16, the engaging portion piece 11 and the reinforcing portion piece 12 are engaged and positioned in the receiving hole 13, and then the nail is driven into the structural material 16 through the nail insertion hole 6 and temporarily fixed. Then, the tip of the tightening bolt 4 is sequentially passed from the front surface 1a side of the board 1 to the insertion hole 6 and the through hole 17, and the tightening nut 18 is screwed and tightened to fix the board 1 side of the joint metal A to the structural member 16. (A lag screw may be used as the fixing means).

Next, the horizontal bridging member 19 is assembled to the joining plate 2 so that the joining plate 2 of the metallic fitting A is engaged with the slit groove 20 formed in the joining plate portion of the horizontal bridging member 19, and the horizontal bridging member is joined. A fixing pin 21 fixed so as to extend over the slit groove 20 on the upper side of 19 is engaged with a recessed edge 9 provided in the joining plate 2 to temporarily latch the horizontal member 19 to the joining plate 2 of the joining metal A. Then, the connection pin 7 is inserted into the pin insertion hole 8 provided in the joint plate 2 through the through hole 22 previously provided on the side of the horizontal member 19 so as to coincide with the pin insertion hole 8 so that the connection hardware A is interposed. The joining work of the structural member 16 and the horizontal member 19 is completed.

Numeral 15 indicates a window which is convenient for carrying, and numeral 22 indicates an engaging groove on the head of the tightening bolt 4.

The insertion holes 5 of the embodiment are arranged so as to be spaced apart from each other. By using the insertion holes 5 at a spaced position, the tightening bolts arranged in the intersecting direction even if they are arranged on the adjacent surfaces of the columns. It doesn't get in the way.

[0014]

[Second Embodiment] FIG. 6 is a perspective view, FIG. 7 is a front view and FIG.
Shows exploded perspective views, respectively, and the second embodiment shown in these drawings omits the reinforcing portion piece 12 used in the first embodiment (thus, the through hole 10 is linear in the center along the longitudinal direction of the substrate 1). Except that the receiving hole 13 is formed in the same manner and the receiving hole 13 also corresponds to this), the description is omitted because it is similar to the first embodiment.

[0015]

Since the present invention has the above-mentioned constitution,
Even if a load is applied to the joining plate, not only the welded portion but also the substrate and the structural material will receive it due to the existence of the engaging piece.
It is possible to provide a load-bearing product even if the structure is simple.

[0016] Further, since the engaging portion is protrudingly provided on the back side of the substrate and there is no welded portion on the back side, the substrate is tightly tightened to the structural material without damaging the structural material. Therefore, the tightening strength does not decrease, and the structural member and the horizontal member can be stably joined.
