  An embodiment in which the metal fitting 40 of the present invention is applied to large acceptance will be described with reference to the drawings. That is, this is an embodiment in which the wooden horizontal member is the large pull 50 and the first wooden member is the base 45.

1. Structure of the receiving metal 40

(1) The metal fitting 40 of the present invention is mainly composed of a first hardware 1 that receives the lower surface 51a side of the large pull 50 (a wooden horizontal member), and a base 45 (a wooden horizontal frame connected to the first hardware 1). It consists of two 2nd metal fittings 20 and 20 joined to (material) (FIGS. 1-3, FIG. 5, FIG. 6).

(2) First, the first hardware 1 will be described. The first hardware 1 includes a horizontal plate 2 that receives the lower surface 51 a of the large pull 50 and vertical plates 4 and 4 that are disposed along both side surfaces 52 and 52 of the large pull 50. That is, the vertical plates 4, 4 are connected to both ends of the horizontal plate 2 having a width corresponding to the width direction of the large pull 50 at substantially right angles, and are substantially U-shaped (substantially horizontal) in an integrated side view. The first hardware 1 having a U-shape. Usually, a strip-like long plate material having a thickness t1 and a width L1 is bent to obtain a horizontal plate 2 having a length (corresponding to the width of the large pull 50) D1 and a length (height, usually from the height of the large pull 50). (Slightly short) H1 vertical plates 4 and 4 are formed.
Here, in the vertical plate 4, the surface where the parallel vertical plates 4 and 4 face (the side on which the horizontal plate 2 is located) is the inner surface 5, and the opposite side is the outer surface 5 a. Further, in the vertical plate 4, the edge on the side where the center side in the length direction of the large pull 50 to be used is defined as one edge 7, and the opposite edge (the end surface 53 side of the large pull 50 = the base 45 side) is the other edge. 7a.

(3) At the upper part of the vertical plates 4 and 4, a step portion 8 is formed in the lateral direction (the direction crossing the width L1) at a distance H10 from the upper end 6 so that the upper end portion of the vertical plate 4 is the distance L10. The connecting portion 10 is formed by parallel translation to the outside. The connecting portion 10 is formed in parallel with the remaining vertical plate 4 (the vertical plate 4 excluding the connecting portion 10 and the stepped portion 8). Therefore, the distance between the connecting portions 10 and 10 between the vertical plates 4 and 4 is as follows.
D1 + 2 × L10
Formed with.

(4) The connecting projections 12 are formed by forming through holes in the connecting portions 10 and 10 and projecting the opening edges of the through holes in a cylindrical shape. The joint projection 12 is formed by burring or the like. The joint convex portion 12 is formed in a direction (inward) in which the connecting portions 10 and 10 of both the vertical plates 4 and 4 face each other, that is, above the step portion 8. Moreover, the joint convex part 12 is the connection part 10, is located in the approximate center part of the width L1 direction, and forms two vertically.
In addition, a lower through hole 15 is formed at a substantially central portion in the width L1 direction below the vertical plates 4 and 4.

(5) Next, the second hardware 20 will be described. The second hardware 20 is formed by bending a belt-like plate material having a thickness t2 and a width L2 so as to have an L shape in plan view including a long connecting plate 21 and a short fixing plate 28.
The width (height) L2 of the connecting plate 21 is formed substantially the same as the height H10 of the connecting portion 10 of the vertical plate 4, and the material thickness t2 of the connecting plate 21 is substantially the same as the protruding length L10 of the step portion 8. It is formed (FIG. 1 (a)). That is,
L2≈H10, t2≈L10
Formed with.
Two through holes (joining recesses) 26 and 26 are formed in the top and bottom (in the direction of the width L2) at a portion of the connecting plate 21 that is in contact with the connecting portion 10 of the first hardware 1. The through hole 26 is formed at a position corresponding to the joint convex portion 12 and when the cylindrical projection of the joint convex portion 12 is inserted into the through hole 26, the through hole 26 is loosely inserted and kept in a fitted state by friction or the like, Moreover, it forms in the insertion state of the grade which can cancel | release a fitting state easily if it operates by hand.
In addition, four fixed through holes 29 and 29 for inserting screws, pins and the like are formed in the fixed plate 28 by four.

(6) The front end of the connection plate 21 of the second hardware 20 is overlapped with the connection 10 of the first hardware 1 formed as described above.
At this time, the fixing plates 28 and 28 of the second hardware 20 are arranged so that the second hardware 20 and 20 are separated from each other. That is, the other surface 22a of the connecting plate 21 of the second hardware 20 is applied to the inner surface 5 of the vertical plate 4 at the connecting portion 10 of the vertical plate 4 of the first hardware 1, and the tip of the fixing plate 28 is connected to the vertical plate 4, 4 is arranged so as to protrude away from the horizontal direction (FIGS. 1, 2A and 2B, external use).
Further, in this state, the cylindrical projections of the joint protrusions 12 and 12 of the connecting portion 10 of the first hardware 1 are loosely inserted into the through holes 26 and 26 of the connecting plate 21 of the second hardware 20 (FIG. 3 ( a) (b)). The joint protrusion 12 and the through hole 26 are loosely inserted, and the inner surface 5 (the inner surface 5 of the vertical plate 4) of the connecting portion 10 of the first hardware 1 and the one surface 22 (fixed) of the connecting plate 21 of the second hardware 20 are fixed. Since the surface on the plate 28 side is in close contact, L2≈H10, t2≈L10.
-The lower edge 23 of the connecting plate 21 of the second hardware 20 is located at the upper edge of the stepped portion 8 of the first hardware 1,
The other surface 22a of the connecting plate 21 of the second hardware 20 (the surface opposite to the fixed plate 28 side) and the inner surface 5 of the vertical plate 4 of the first hardware 1 are arranged flush with each other.
The upper edge 23 of the connection plate 21 of the second hardware 20 is arranged at substantially the same height as the upper edge 6 of the connection portion 10 of the first hardware 1,
The tip edge 24 of the connecting plate 21 of the second hardware 20 is arranged so as to substantially coincide with the one edge 7 of the vertical plate 4 of the first hardware 1 in plan view.
It becomes.
Further, in this state, the protrusion height L12 of the joint protrusion 12 from the inner surface 5 of the connecting portion 10 of the first hardware 1 is smaller than the depth of the through hole 26 of the second hardware 20 (that is, the material thickness t2). Since it is formed, the distal end 13 of the joint convex portion 12 is positioned L30 inside the other surface 22a of the connecting plate 21 and is accommodated in the through hole 26 (FIG. 3B). Accordingly, even when an impact is applied to the hardware 40 in a state where the first hardware 1 and the second hardware 20 are assembled, the tip 13 of the cylindrical protrusion of the joint convex portion 12 is hit and friction is generated. Accordingly, it is possible to prevent the cylindrical protrusions 12 of the joint projections 12 from being unintentionally slipped out or being bent and bent and not being accidentally detached from the through holes (joint recesses) 26.

(7) In the manner described above, the large pull receiving metal 40 is formed (FIGS. 1 and 2).

2. Use of hardware 40

(1) The metal receiver 40 is transported from the factory to the construction site in a state where the first hardware 1 and the second hardware 20 are separated (FIG. 1). At this time, since the first hardware 1 and 1 and the second hardware 20 and 20 can be stacked and packed, the bulk can be reduced and the conveyance cost can be reduced.

(2) Moreover, since it can be loosely fitted only by inserting the joint convex parts 12 and 12 of the 1st metal fitting 1 in the through-holes 26 and 26 of the 2nd metal fitting 20 in a construction site, an operator uses a tool. It is possible to easily assemble the bracket 40 without any trouble. Even if the mounting direction of the second hardware 20 is wrong, the operator can easily remove it by hand and change it to the correct orientation.

(3) A base (first wooden member) 45 is fixed on a concrete base 43 with anchor bolts (not shown) or the like.
The assembled metal receiving object 40 can be fixed to the side surface 46 of the base 45 by hitting screws from the fixing through holes 29 and 29 of the fixing plate 28 of the second metal object 20. Further, the large pull 50 is aligned with the base 45, and the lower surface 51 a of the large pull 50 is placed on the horizontal plate 2 of the first hardware 1 of the receiving metal 40. In this state, the other surface 22a of the connecting plate 21 of the second hardware 20 (the surface opposite to the fixed plate 28 side) and the inner surface 5 of the vertical plate 4 of the first hardware 1 are formed flush with each other. The both side surfaces 52, 52 of the large pull 50 can be in close contact with the metal fitting 40 (the other surface 22 a of the connecting plate 21 of the second hardware 20 and the inner surface 5 of the vertical plate 4 of the first hardware 1).
Subsequently, a screw is hit toward the large pull 50 from the outer surface 5a side of the vertical plate 4 of the first hardware 1 to the lower through holes 15 and 15, and a screw is also hit toward the large pull 50 at the joint projections 12 and 12. . As described above, the large pull 50 can be fixed to the base 45 (FIGS. 6A and 6B).

3. Arrangement of other second hardware 20 and use of receiving hardware 40

  In such an internal use, the metal fitting 40 is applied to the side surface 46 of the base 45, and first, the screws 56, 56 are struck from the fixing through holes 29, 29 of the fixing plates 28, 28 of the second hardware 20, The metal fitting 40 is fixed to 45. Thereafter, the large pull 50 is placed on the metal receiver 40 and fixed (FIG. 7).

  In addition, in the case of such internal use, when there are other hardware or wooden members interfering with the fixing plates 28, 28 of the second hardware 20 in the vicinity of the large pull 50 (or beam, etc.) to be attached. Even so, construction is possible. In addition, when applied to a pillar such as a through pillar as the first wooden member, the receiving hardware 40 (particularly, the fixing plate 40 of the second hardware 20) fits within the width of the pillar and can be constructed (not shown). .
