DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. 1 to 9. Although the joining of each member constituting the door frame will be described here, the present invention can be widely applied to joining members at an angle of approximately 90°, regardless of the types of members to be joined to each other. It is.

The door frame 10 shown in FIG. 6 is formed in a rectangular shape surrounding a door 12, and includes a pair of left and right vertical frames 14 extending vertically, and a horizontal frame 14 joined to the upper ends of both vertical frames 14. It is composed of an upper frame 16 and a horizontal lower frame 18 joined to the lower ends of both vertical frames 14.

As shown in FIG. 1, both left and right edges of the vertical frame 14 are bent outward (toward the front in FIG. 1).
As a result, ribs 141 are formed, and this vertical frame 1
A protrusion 142 having a U-shaped cross section and extending inward from the frame is formed in the center of the frame 4 over the entire upper and lower regions. Further, at the upper end of the center portion of the vertical frame 14, a notch 143 is formed which is U-shaped in front view and opens upward.

Further, a pair of front and rear tenons 144 are protruded from the upper end of the vertical frame 14, and a through hole (wedge-shaped object insertion portion) 145 is formed through the tenon 144, which is rectangular in front view. has been done.

On the other hand, both edges of the upper frame 16 are bent upward to form ribs 161, and
It has a shape in which a protrusion 162 with a U-shaped cross section is formed in the center thereof and protrudes downward.

Furthermore, at the positions corresponding to the tenons 144 of the vertical frame 14 at both left and right ends of the upper frame 16, there are mortise holes 163 having a shape that allows the tenons 144 to pass through.
is drilled.

On the other hand, the lower frame 18 has a U-shaped cross section opening downward, and the vertical frame 1 is provided at both left and right ends of the lower frame 18.
A tenon 181 similar to the tenon 144 in No. 4 is provided in a protruding manner, and a through hole (wedge-shaped object insertion portion) 182 that is rectangular in plan view is also provided through this tenon 181 . In contrast,
A mortise hole 146 is bored at the lower end of the vertical frame 14 at a position corresponding to the tenon 181.

Next, a method of joining the vertical frame 14 and the upper frame 16 and a method of joining the vertical frame 14 and the lower frame 18 will be explained.

First, the tenon 144 of the vertical frame 14 is inserted into the mortise hole 163 of the upper frame 16 until it passes through it. As a result, the upper frame 16 is positioned with respect to the vertical frame 14 in the front-rear direction and the left-right direction, and the through-hole 1 of the tenon 144 is
45 faces above the upper surface of the upper frame 16.

Next, the wedge 20 is driven into the through hole 145 from the side. This wedge 20 is shown in Figures 1 and 3.
As shown in , it is preferable that the lower surface is horizontal and the upper surface is tapered. By press-fitting the wedge 20, the upper frame 16 is pushed down with respect to the vertical frame 14, and the upper end of the vertical frame 14 is pressed against the lower surface of the upper frame 16 at an angle of 90°. Therefore, by welding the vertical frame 14 and the upper frame 16 in this state, the vertical frame 14 and the upper frame 16 can be joined accurately and quickly without requiring assistance as in the conventional case. Can be done. The welding here may be performed at the corner 22 formed by the upper surface of the upper frame 16 and the wedge 20 as shown in FIG. 3, or at the corner 22 formed by the vertical frame 14 and the upper frame 16 as in the conventional It may also be applied to the corners 24 where the coating is applied.

Similarly, the tenon 181 of the lower frame 18 is inserted into the mortise 146 of the vertical frame 14 from the inside, and this tenon 18
By driving the wedge 20 into the through hole 182 of 1, the side surface of the vertical frame 14 and the side end of the lower frame 18 can be brought into pressure contact. Therefore, by welding the vertical frame 14 and the lower frame 18 in this state, the two can be joined accurately and quickly, and the structure shown in FIGS. 2 to 5 is finally obtained. be able to.

[0024] After the joining is completed, the wedge 2
0 may be left as it is, or if the wedge 20 is not welded, the wedge 20 may be removed. Furthermore, the "wedge-shaped object" according to the present invention is not limited to a disposable one such as the wedge 20 described above, but also a tool 26 having a wedge-shaped tip 261 as shown in FIG. 2
After welding is performed with the tip portion 261 of No. 6 press-fitted into the through hole 145, 182, the tip portion 261 is inserted into the through hole 1.
45,182 and this tool 26 may be used again for another joining.

Next, a second embodiment will be explained based on FIGS. 10 to 17.

In this embodiment as well, tenons 147 and 183 are protruded at the same positions as in the first embodiment.
These tenons 147, 183 have a T-shape in which notches 148, 184 are respectively provided on both sides of the portions extending deeper than the tips thereof.

On the other hand, the wedge for joining is shown in FIG. 11(a).
A wedge 28 as shown is used. This wedge 28 is formed by bending a single plate made of metal or the like by an obtuse angle α, and a recess 281 is formed at one end (the upper end in FIG. 11(a)). As a result, protrusions 282 are formed on both sides thereof. The width of the recess 281 is set such that both protrusions 282 can be inserted into the notches 148, 184 of the tenons 147, 183, respectively.

In this structure as well, the tenons 147 and 183 are connected to the mortise hole 163, as in the second embodiment.
, 146, the protrusions 282 of the wedge 28 are press-fitted into the notches 148, 184 exposed from the mortises 163, 146, respectively, as shown in FIGS. , 18 can be positioned and pressed against each other, and from this state, joining work can be easily performed by welding.

[0029] Note that the notch 14 of the tenon 147, 183
The wedge to be press-fitted into 8,184 is shown in Fig. 11(b).
The wedge 30 may be a block having a notch 301 and a pair of protrusions 302 at the end as shown in FIG. However, if the wedge 28 is formed from a single plate as shown in FIG. 2(a), the material cost will be saved compared to the wedge 28 shown in FIG. This has the advantage of increasing the pressure contact effect between them.

In the case of this structure, after the wedge 28 and the like are press-fitted, a blow is applied to the tenon 147 from the direction shown by arrow A1 in FIG. 13, for example, to bend the tenon 147 as shown in FIGS. 16 and 17. By doing so, it is also possible to join the vertical frame 14 and the upper frame 16 without welding. Further, the same effect can be obtained by bending the tenon 183 by applying a blow to the tenon 183 from above.

Next, a third embodiment will be explained based on FIGS. 18 to 23.

Here, as in the previous embodiment, the vertical frame 14
In the tenon 149 projecting from the bottom frame 18, a notch 148 is provided only on the sides facing each other, and in the tenon 185 projecting from the lower frame 18, the tenon 18
5 is inserted into the mortise 146 of the vertical frame 14, a notch 1 is formed only on the side facing the rib 141 of the vertical frame 14.
84 is formed.

On the other hand, a single common wedge, ie, the wedge 32 shown in FIG. 19, is used as the wedge press-fitted into both the notches 148. This wedge 32 is formed by bending a single plate material and has a width dimension d1 equal to the distance between both notches 148, and when both tenons 149 are inserted into the mortise hole 163, it is , 22, both notches 1
The structure is such that the wedge 32 can be press-fitted into the wedge 48 at the same time. Further, as the wedge press-fitted into the notch 184, the wedge 34 shown in FIG. 20(a), that is,
A width dimension d2 that is formed by bending a single plate and is equal to the distance between the notch 184 and the rib 141.
The wedge 34 having the above-mentioned tenon 185 is inserted into the mortise hole 146, and the notch 184 and the rib 1
41 as shown in FIG.
4 can be press-fitted.

According to this structure, the pair of tenons 14
By standardizing the wedge 32 used for the notch 184 and the rib 141, it is possible to simplify the wedge press-fitting work, reduce the number of parts, and simplify the shape of the wedge 32 itself. By configuring the wedge 34 to be press-fitted therebetween, there is an effect that the shape of the wedge 34 itself can be simplified. Also, in this structure, by bending each tenon 149, 185 after press-fitting the wedges 32, 34, it is possible to join the vertical frame 14 and the upper and lower frames 16, 18 without welding. It is.

[0035] Also in this structure, the wedge 3
4, it is also possible to use a block-like wedge 36 as shown in FIG. , it is possible to improve the pressing effect due to the elastic force. This also applies to the wedge 32 shown in FIG.

Although the above embodiment shows the case where the present invention is applied to the door frame 10, the present invention is not limited to this, and can be applied to various cases where two members are joined at an angle of approximately 90°. It is possible to apply it to

[0037]

As described above, the present invention provides a protruding tenon having a wedge-shaped insertion portion on one of the members to be joined to each other, and a tenon having a wedge-shaped insertion portion protruding from the other member at the location where the joining end portion is joined. A mortise hole into which a tenon can be inserted is provided, and with the tenon inserted into the tenon until it passes through the tenon, a wedge-shaped object is press-fitted into the wedge-shaped object insertion part to press the two members together. Since the two members are welded in this pressure-welded state, there is no need for an assistant to position and hold each member while the members are being joined, which is required in the conventional method. With parts pressed together by press-fitting objects, joining work by welding can be easily performed with almost no help from an assistant, and this has the effect of contributing to a reduction in product costs. .
