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 A beam is provided on the back side of a flat plate-shaped fixing member made of a single metal plate, which abuts against a structural member such as a pillar or a shoulder, and abuts against the structural member and abuts against the structural member. A base end of a plate-shaped joining material made of a single metal plate is welded to a cutting groove provided at a joining end portion of the joining material and assembled with the joining member. Some have a structure.

[0003]

In this type of joint fitting for a building, a fixing member is fixed to a column or a gap, and the joining member is assembled to a horizontal member so that the horizontal member is supported by the column or the like. Therefore, the load resistance is required, and the load resistance is required, so that the thickness of the fixing member or the like must be appropriately large.

[0004] Therefore, the weight is large, and it is desired to reduce the weight for work at high places.

[0005] Further, since a gap is formed between the pillar and the like and the horizontal member depending on the thickness of the fixing material, it is necessary to provide a concave portion on the side of the pillar and engage the fixing material with this. It has to be complicated.

The present invention has been made with a view to such a conventional example, with the object of providing a metal joint for a building having such a structure.

[0007]

[Means for Solving the Problems] On the front side of a flat plate-shaped fixing member that abuts the back surface against a structural member such as a pillar or a trunk, and is fastened to the structural member, provided at the joint end of a horizontal member such as a beam. A pair of superposed plates that are continuous with each other via a folded portion on a free end side in a building joint metal having a base end of a plate-shaped joining material that is engaged with the cut groove and that is assembled with the horizontal member with each other. To form a bonding material, and a superposed plate of the bonding material is folded back in opposite directions on a base end side corresponding to the free end side to form a fixing material.

[0008]

1 is a front view, FIG. 2 is a partially cutaway plan view, and FIG.
1 is a right side view of FIG. 1, and FIG. 4 is a sectional view showing a used state.

In the drawing, reference numeral 1 denotes a joining material composed of a pair of superposed plates 1 'and 1' which are continuous with each other via a folded portion 1a on the free end side, and the joining material 1 is provided at the upper end of the folded portion 1a. A beam is provided on a beam (or other horizontal member) 11 for receiving a retaining rod 12. A pair of upper and lower insertion holes 3 for a drift pin 13 are provided below the concave edge 2. , 3 are provided.

[0010] 4 is a superposed plate 1 ', 1 constituting the bonding material 1
'Is a fixing member which is formed by bending a base end side corresponding to the free end side in directions opposite to each other (in a direction perpendicular to the bonding material 1), and a plate of the fixing material 4 via the bonding material 1 The two pieces 4 ′ and 4 ′ have an insertion hole 5 for a through bolt 15 for fastening to a pillar (or a body difference) 14 and a through hole 6 for nail attachment.

Reference numeral 7 denotes a superposed plate 1 constituting the bonding material 1.
′, 1 ′ are bent at 180 ° with respect to the superposed plates 1 ′, 1 ′, and the partial pieces 7 ′, 7 ′ obtained by cutting and raising the upper and lower two portions on the base end side are projected in the direction of the back surface 4 b of the fixing material 4. It is an engaging material formed by superposing each other.

A metal joint made of the joining material 1, the fixing material 4, and the engaging material 7 is formed by bending a metal plate cut into a predetermined shape, and the superposed plate 1 ', 1
The right places between the 'are welded together and reinforced.

Thus, the through hole 16 corresponding to the insertion hole 5 provided in the fixing member 4 and the receiving hole 17 corresponding to the contour shape formed by the engaging member 7 protruding from the back surface 4b side of the fixing member 4 are formed.
4, the engaging member 7 is engaged with the receiving hole 17 and positioned, and then the nail is driven into the pillar 4 through the through hole 6 and temporarily fixed, and the insertion hole is formed from the surface 4 c side of the fixing member 4. The fixing member 4 side of the metal joint A is fixed to the column 4 by sequentially screwing the tightening nut 18 through the end of the through bolt 15 through the through hole 5 and the through hole 16 (even if a lag screw is used as a fixing means). good).

Next, the beam 11 is combined with the joining material 1 so that the joining material 1 of the joining hardware A is engaged with the notch groove 19 formed at the joining end of the beam 11, and The locking rod 12 fixed so as to pass through the slit 19
Is engaged with the concave edge 2 provided in the joining material 1 to temporarily hook the beam 11 to the joining material 1 of the joint metal A, and the beam 11 coincides with the insertion hole 3 provided in the joining material 1. The drift pin 13 is made to penetrate through a through hole 22 previously provided on the beam 11 side so that the column 14 and the horizontal
This is the end of the joining operation with No. 1.

In the embodiment, the through holes 16 are arranged at intervals, so that the through bolts interfere with each other even if they are arranged in a direction crossing other jointed hardware. Never be.

The engaging member 7 is used to increase the burling strength generated when the load of the beam 11 is applied to the metal joint A.

[0017]

As described above, since the present invention is formed by bending a single metal plate, the fixing material can be reduced in weight, suitable for mass production, and requires a smaller plate thickness than the bonding material. The side can be made thinner, so that a small amount of gap corresponding to the thickness of the fixing material generated between the column and the horizontal member is small, so that there is no need to form a concave portion of the fixing material on the side of the column and the like. It is a target.
