In the other wood hooked, the connection hole in which the engagement shaft is not inserted is configured to match the insertion hole of the building material connection fitting, and the connection hole has a pin,
By driving or inserting a connecting shaft such as a bolt, the other timber and the building material connecting fitting are completely fixed.

[0006]

In the above-mentioned building material connecting metal fitting, the connection between the supporting surface portion and the other wood can be firmly fixed by the chin rest portion, the engaging shaft, and the insertion hole and the connecting shaft. Since the surface portion is fixed to the surface of one of the timbers with a bolt or the like, it is difficult to secure the strength. Further, if the thickness of the wood for fixing the fixing surface portion is thick, it is difficult to fix because the bolt and the shaft hole for inserting the bolt become long, and for example, it is practical to fix the building material connection fitting to the end surface of the shaft material. Is impossible. Therefore, the above-mentioned building material connecting fitting has a problem in that it cannot be used with a high degree of freedom to connect various timbers, since the fixing position and the mode of use are limited.

The embedded metal fitting includes an insertion portion and an engagement plate configured to bend and project from the insertion portion and extend along the surface of the building material.

According to this means, it is possible to fix to the building material by inserting the insertion portion into the building material and inserting the fixed shaft from the outside of the building material into the through hole to fix it.
In this fixed state, the other metal fitting can be engaged by the engagement plate extending along the surface of the building material.

Here, it is preferable that the insertion portion is formed with a bent edge portion extending along the insertion direction. According to this means, the bending edge portion can increase the rigidity against bending and breaking of the insertion portion, and the connection strength can be improved.

Further, it is preferable that the through hole is formed in a shape extending in the inserting direction of the inserting portion. According to this means, since the through-hole of the insertion portion inserted into the building material is formed in an extended shape, when driving screws, bolts, pins, etc. from the need to attach other metal fittings to the building material, Since it is possible to insert these into parts other than both ends of the extended-shaped through hole, it is possible to freely work on the building material to some extent.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of a building material connecting fitting according to the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, this embodiment includes an embedded metal fitting 10 configured to be embedded and fixed in the interior of wood, and a chin bracket 20 configured to be fixed to the surface of the wood. It is configured.

The embedded metal fitting 10 has an insertion portion 11 having a through hole 11a having a vertically elongated oval cross section in the central portion, and the insertion portion 11
Bent edges 12 and 12 formed on both side edges of the
1 and an engaging plate 13 which is bent from the upper part of the No. 1 and extends in the horizontal direction and which is provided with an engaging hole 13a.

The general usage of this buried metal fitting 10 is as follows.
As shown in FIG. 1, a deep hole b having a rectangular cross section is formed in an end surface a of a wood A such as a pillar or a beam, and an insertion portion 11 is inserted into the deep hole b to make a horizontal surface (not shown) from the side surface of the wood A. A shaft hole extending in the direction is bored, and the bolt 15 shown in FIG. 2A is inserted through the shaft hole and the lower end of the through hole 11a and fixed by a nut. At this time, the engagement plate 13 formed on the upper portion of the embedded metal fitting 10 is in a state of protruding on the end surface a.

Here, the through hole 1 formed in the buried metal fitting 10
1a is, in addition to the bolt 15, a bolt 14 necessary for attaching other building material connecting fittings or beams to the side surface of the wood A, for example.
Is formed so that the bolt 15 can be inserted therethrough, and if there is no need for this, a single circular cross-section through which the bolt 15 is inserted may be formed.

The jaw fitting 20 is constructed so as to be fixed to the end surface a of the wood A, and has a fixed surface portion 21 fixed to the end surface a, and is bent upward from both sides of the fixed surface portion 21. The two support surface portions 22 and 22 extending in the direction of 1 are formed from a single metal plate material.

The fixing surface portion 21 has two fixing holes 21a, 2a.
1a and an opening 21b formed at an intermediate position between these are provided. The fixing hole 21a has a circular cross section, and the opening 21b is formed in a shape having a pair of slits 21c at opposing positions outside the hole having a circular cross section.

The supporting surface portion 22 as a whole is provided with slightly inclined side edges, and the plate surface thereof has a chin rest portion 22a having an opening in the upper peripheral edge and a horizontal plane including the position of the chin rest portion 22a. The first upper position, the second position downward from the chin rest 22a parallel to the side edge, and the third position downward from the first position parallel to the side edge. The hole 22b is formed.

3A and 3B show the structure of the chin bracket 20. FIG. 3A is a side view, FIG. 3B is a front view, and FIG. 3C is a plan view. As shown in FIG. 3 (c), the opening 21 b formed in the fixed surface portion 21 is provided with a slit portion 21 c extending almost the entire width of the fixed surface portion 21.
The c is configured so that the engaging plate 13 of the embedded fitting 10 can be inserted therethrough.

The side edge of the support surface portion 22 of the chin rest 20 is shown in FIG.
Although it is inclined as shown in (a), it does not necessarily have to be inclined and may stand upright. However, since the side edges are inclined, when connecting a sloped tree or the like on the end surface of the wood A, it becomes easy to handle over a wide range of the slope angle, and The supporting surface portion 22 does not protrude from the tree whether the inclination angle is slightly larger or smaller than the inclination angle of the side edge, which is preferable in appearance and has an effect that there is little trouble in mounting surrounding building materials. .

FIG. 4 shows a state of the embedded metal fitting 10 and the chin bracket 20 when a wood material (for example, a tree) C is connected on a wood material (for example, a pillar) A, and FIG. 5 shows a similar structure. Figure 4
It shows a state viewed from a direction orthogonal to the direction of.
In this case, the engagement plate 13 of the embedded metal fitting 10 is the jaw fitting 20.
It is introduced upward from the opening 21b provided in the fixed surface portion 21, and is fixed in a state of being superposed on the fixed surface portion 21 such that the fixed surface portion 21 is pressed against the end surface a of the wood A from above. The fixing of the embedded metal fitting 10 is performed through the through hole 11 as described above.
It is performed by a bolt 15 inserted at the lower end of a.

The chin rest 20 is fixed by fixing means 16 and 17 such as bolts, screws, fixing pins and the like inserted through the fixing holes 21a with the fixing surface portion 21 in contact with the end surface a of the wood A. Here, when the wood A is a beam, it can be fixed by forming a vertical hole in the wood A and inserting a bolt, but in this case, the position where the fixing means 16 and 17 are inserted is planarly arranged. It is necessary to deviate from the insertion positions of the bolts 14 and 15. On the other hand, when the wood A is a pillar as shown in FIG. 1, it is impossible to fix it with bolts. Therefore, a coach screw or the like is inserted into the fixing hole 21a and screwed into the wood A, or a short fixing pin is fixed. It is necessary to insert it into the hole 21a and drive it into the wood A.

In this case, the engaging hole 13a formed in the engaging plate 13 of the embedded metal fitting 10 is fixed to the fixed surface portion 21 of the jaw fitting 20.
It is preferable to form the fixing hole 21a so that its axis coincides with the axis line. In this case, since the common fixing means 16 can be inserted and fixed through the engaging hole 13a and the fixing hole 21a, a strong fixing can be achieved. However, the engagement hole 13a is not always necessary, and the engagement plate 13 may be formed so as not to interfere with the fixing of the fixing surface portion 21. This is because the engaging plate 13 of the embedded metal fitting 10 has the fixed surface portion 21.
Also, by pressing in the state of being superimposed on
This is because the embedded metal fitting 10 can support the chin rest metal fitting 20.

If necessary, the inner surfaces of the engaging hole 13a and the fixing hole 21a which are overlapped with each other can be fixed by welding. By welding, it is impossible to remove both fittings, but they can be securely fixed. The welding may be performed between the peripheral edge portion of the engagement plate 13 and the fixed surface portion 21 instead of the engagement hole 13a and the fixed hole 21a.

The wood C is engaged with the jaw fitting 20 connected to the embedded fitting 10 fixed to the wood A from above.
The wood C is preliminarily formed with slot grooves c, c configured to accommodate the two support surface portions 22, and an engaging shaft D made of a bolt or the like is inserted through the slot grooves c.
Has been fixed. When the wood C is hooked so that the support surface portion 22 is accommodated in the slot groove c, the engagement shaft D engages with the jaw hook portion 22a. In this state, the wood C is fixed to the jaw fitting 20 by inserting or driving the connecting shaft E including a bolt and a driving pin into the previously formed connecting hole and inserting the connecting shaft E into the inserting hole 22b.

The embedded fitting 10 and the chin rest 20 have the effect that the building materials can be firmly connected by combining them, but the chin rest 20 can be used alone as a building material connecting fitting. Two fixing holes 21a, 21a and an opening 21b are formed in the fixing surface portion 21 of the chin holder 20, but the opening 21b is formed with two slits 21c, 21c more than the fixing hole 21a. Since it is only provided as a fixing hole, the jaw fitting 20 can be fixed to the surface of the building material with bolts or the like through the three fixing holes.

FIG. 6 is a perspective view showing a mode in which the above-described embodiment is used for different parts. In the case shown in this figure, the embedded metal fitting 10 is inserted into the deep hole f1 formed in the beam F, and the opening of this deep hole f1 is arranged on the bottom surface of the concave groove f2 formed in the upper surface of the beam F. The fixing surface portion 21 of the chin rest 20 is configured to fit in the groove f2. In this case, the fixing surface portion 21 of the jaw fitting 20 can be fixed to the beam F by inserting a bolt into the fixing hole 21a and the opening 21b, but the bolt shaft protrudes to the lower surface of the beam F. The embedded metal fitting 10 is used in order to avoid this and to more firmly fix the chin hanging metal fitting 20.

Also in this example, the engagement plate 13 and the fixing surface portion 21 are fixed by welding or by using a fixing means 16 such as a coach screw. The position of the engagement hole 13a formed in the engagement plate 13 of the embedded metal fitting 10 is determined by the two fixing holes 2 formed in the fixing surface portion 21 of the jaw fitting 20.
If it is configured so as to match with both 1a and 21a, it can be used without any problem even if the embedded fitting 10 is engaged with the jaw fitting 20 in any posture. Also in this case,
In order to fix the other crosspiece G to the beam F, a bolt or a pin for inserting the embedded metal fitting 10 may be required. Therefore, the through hole 11a formed in the embedded metal fitting 10 is formed in an extended shape. ing.

In the structure shown in FIG. 6, the groove f2 is formed so that the chin hook 20 is hard to be seen from the outside at the connecting portion.
However, the groove f2 is not always necessary. In addition, although the case where wood is connected is described in the above embodiment, the building material connecting fitting of the present invention is not limited to wood, and various building materials made of various materials such as synthetic resins, metals, and ceramics can be used for various building materials. This is applicable when connecting and connecting in various modes.

[0036]

As described above, according to the present invention, the embedded fitting and the chin rest can be engaged and firmly connected by overlapping the engaging plate with the fixed surface portion, so that the embedded fitting can be firmly connected. It is possible to firmly connect one building material that has been inserted with the other building material that is engaged with the chin rest metal fittings, and by using the embedded metal fittings, there is no need to select the structure, location, mounting mode, etc. of the building material The tool can be fixed. Moreover, the chin holder can be used alone.
