And a third joint surface which is continuous with the front side of the first joint surface and extends in a direction bent at an angle of 270 degrees or more.

Further, the female connector has first to third surfaces to be joined corresponding to the first to third surfaces to be joined, and these surfaces to be joined correspond to the first to third.
It is possible to superimpose them on the joint surface in close contact at the same time.

Then, the first to third joint surfaces of the male-side connector fixed to one member are connected to the first to third jointed surfaces of the female-side connector fixed to the other member. The surfaces are overlapped and brought into close contact with each other, and the male-side connector and the female-side connector are fastened and fixed to each other by using the fastener, thereby forming the connection state of the first and second members. There is.

In the member connecting structure of the present invention, the first to third joint surfaces of the male connecting device fixed to the one member side are connected to the female connecting device first to the other member. 1
It is possible to connect both members by a simple operation of overlapping the third surfaces to be joined and fastening these connecting tools with a fastener. In addition, in the state where the female connector is overlapped with the male connector, since the three inclined surfaces are overlapped as described above, the positions of those surfaces in the front-back direction and the vertical direction are automatically determined. Stipulated in. Therefore,
The subsequent fastening work and the like can be easily performed.

Here, in order to prevent both connecting tools from shifting in the left-right direction, the following configuration may be added in addition to the above configuration.

BEST MODE FOR CARRYING OUT THE INVENTION A connection structure of members to which the present invention is applied will be described below with reference to the drawings.

FIG. 1 shows an example in which the present invention is applied to a connecting portion between a pillar and a beam in a lightweight steel building. In this figure, 1 is a column made of a light weight steel square pipe, and 2 is a beam made of a light weight steel square pipe. A male-side connecting fitting 3 to which the present invention is applied is fixed to the side surface of the pillar 1 by welding or the like. A female-side connecting fitting 4 to which the present invention is applied is also fixed to the joint of the pillar 2 by welding or the like. These male side connection fittings 3 and female side connection fittings 4
Are fastened and fixed to each other by fastening bolts 5 and nuts 6.

FIG. 2 is an exploded perspective view of the male connecting fitting 3. The structure of the male-side connecting fitting 3 will be described with reference to FIGS. 1 and 2. The male side fitting 3 is composed of a pillar fixing side fitting 7 and a joining side fitting 8. The column fixing side metal fitting 7 is formed by bending a steel plate, and has a rectangular rear wall 71 and left and right side walls 72 and 73 that are bent from the left and right sides of the rear wall 71 toward the front at right angles. It is

A circular hole 7 is provided at a position above the center of the rear wall 71.
1a is formed. The left and right side walls 72, 73 have the same shape, and the first end faces 72a, 73a are inclined slightly upward on the front side with respect to the horizontal, and are bent continuously at an angle of less than 90 degrees to the rear side thereof. The second end faces 72b, 73b extending upward and the first end faces 72a, 7b.
3a is provided with third end faces 72c, 73c which are bent continuously at an angle of 270 degrees or more and extend downward on the front side of 3a. Horizontal upper end surfaces 72d and 73d are continuous with the upper ends of the second end surfaces 72b and 73b, and horizontal lower end surfaces 72e and 73e are also at the lower ends of the third end surfaces 72c and 73c.
Is continuous.

On the other hand, the joining-side metal fitting 8 is also made by bending one steel plate, and the left and right side walls 72, 7 are formed.
3 is bent so as to have a shape that matches the contour shape of the end face. That is, the first end faces 72a, 73
a first joint surface 81 that matches a, a second end surface 72b,
73b and the 2nd joint surface 82 and the 3rd end surface 72
It has a third joint surface 83 corresponding to c and 73c.
Therefore, with respect to the first joint surface 81, the second joint surface 82
Is bent upward at an angle of less than 90 degrees, and the third joint surface 83 is bent downward at an angle of 270 degrees or more. In this example, a horizontal upper end surface 84 is formed continuously with the upper end of the second joint surface 82.

A circular hole 81a for a fastening bolt is formed in the center of the first joint surface 81. In addition, circular holes 82 are formed in the centers of the second and third joint surfaces 82 and 83, respectively.
a and 83a are formed. The joining side metal fitting 8 having such a configuration is joined to the column fixing side metal fitting 7 by welding.

On the other hand, as shown in FIG.
Also has the same shape as the male-side connecting fitting 3. Therefore, FIG.
In, the corresponding parts are designated by the same reference numerals. However, as shown in FIG. 1, the beam 2 is fixed to the joint in an upside down state.

FIG. 3A shows a state in which a beam 2 is bridged and fixed between a pair of columns 1 and 1A. As shown in this figure, male side connection fittings 3 and 3A are fixed to the opposite side surfaces of the pair of columns 1 and 1A in a bilaterally symmetrical state. Similarly, the female side fittings 4 and 4A are fixed to the left and right joints of the beam 2 in a bilaterally symmetrical manner. Pillar 1, 1A
Since the distance between them and the span of the beam are several meters, they can be moved from side to side by several millimeters. Accordingly, if the beam 2 is dropped from above between the pair of pillars 1 and 1A, as shown in FIG. 4A is forcibly inserted.

FIG. 3 (B) shows the state of the male connecting fitting 3 and the female connecting fitting 4 on one side which are superposed in this way. As shown in this figure, the male side fitting 3
The first, second, and third joint surfaces 81, 82, and 83 of the female connecting fitting 4 are in close contact with the first, third, and second joint surfaces 81A, 83A, and 82A, respectively. Has become.

Here, the first joint surfaces 81 and 81A are inclined surfaces which are inclined with respect to the horizontal direction in the beam-to-beam direction (front-back direction). Therefore, the pair of first bonding surfaces 81 and 81A are overlapped with each other, so that the displacement in the beam direction is prevented. In addition, the second and third joint surfaces 82, 8
2A and 83, 83A are bent in a direction approaching the first joint surfaces 81, 81A in the beam-to-beam direction.
Therefore, the vertical displacement can be prevented by overlapping these surfaces. Furthermore, since the beam 2 is forcibly dropped between the pillars 1 and 1A, the female-side connecting fitting 4 is unlikely to come off from the male-side connecting fitting 3.

After the connection fittings 3 and 4 are stacked on each other, the fastening bolt 5 is passed through the circular holes 81a formed in the first joint surfaces 81 of both of them, and the nut 6 is tightened from the rear surface side. This tightening work can be easily performed because the displacement between the metal fittings 3 and 4 is prevented as described above.

As described above, by using the connection fittings 3 and 4 of this example, the pillar and the beam can be connected by a simple operation.

(Modification of Connection Metal Fitting) FIG. 4 shows a connection metal fitting according to another embodiment of the present invention. The basic structure of the connecting fittings 3B and 4B is the same as that of the connecting fittings 3 and 4 described above. However, the first of the one side wall 72
The projection wall 72f is formed by extending the end surface 72a and the second end surface 72b to the upper end surface 72d.

Therefore, when the male-side connecting fitting 3B and the female-side connecting fitting 4B are superposed on each other, they are displaced in the left-right direction by the plate thickness of the protruding wall 72f. In this superposed state, the inner side surface 72g of the protruding wall 72f on one side is
Comes into contact with the side wall 72 on the other side. Therefore,
When the connecting fittings 3B and 4B are superposed on each other, they are not displaced not only in the front-back direction (beam direction) and the vertical direction but also in the horizontal direction (column row direction). Therefore, if this configuration is adopted, it is possible to form a state in which the front and rear, the left and right, and the top and bottom are not displaced only by overlapping the connecting fittings. For this reason, the subsequent fastening work and the like becomes extremely simple.

(Other Embodiments) In the connection fittings 3, 4 or 3B, 4B described above, the male side and the female side are common fittings of the same shape. Alternatively, the male side and the female side may have different shapes. In either case, it is sufficient that each of them has a first joint surface, a second joint surface and a third joint surface.

Although the above example is a connection structure for a lightweight steel frame building, the present invention can also be used as a connection structure for a wooden column and a beam. In this case, for example,
As shown by an imaginary line arrow in FIG. 3B, the male-side connecting fitting 3 and the female-side connecting fitting 4 may be fixed to the pillar and the beam sides using fastening screws or the like.

Further, in the above example, the connecting fitting is made of a steel plate as the connecting tool. The connection tool may be a material other than a steel plate, for example, a molded product such as hard plastic in the case of a connection structure for a light structure. Alternatively, it may be formed from a metal material other than a steel plate.

Furthermore, in the above-mentioned example, the present invention is applied to the connecting portion between the column and the beam. Of course, it may be applied to the connection portion of members other than this.

In the present invention, the inclination angles of the first, second and third joint surfaces may be appropriately set according to the scale of the symmetrical structure to be used.

[0034]

As described above, in the member connecting structure of the present invention, the male side having the first joint surface and the second and third joint surfaces with the inclination angle set to a predetermined value. A connector, a female-side connector having similar first and third joint surfaces, and a fastener for fastening and fixing these connectors, and using these to connect between different members I am trying to do it. In connection work, it suffices to stack the female-side connector on the male-side connector and fasten them to each other, which is easy and requires no skill.

Further, the connecting tool of the present invention comprises first to third parts.
When the two connecting tools are overlapped with each other by the joint surface, the mutual displacement is prevented. In particular, in the case of using the connector provided with the projecting wall, there is an advantage that the displacement in the front-rear direction, the left-right direction, and the up-down direction can be prevented only by overlapping the two connection devices.
