Various things are included irrespective of the hierarchy, such as a second-floor building provided continuously with a floor building.

In the present embodiment, the basic truss 2 is composed of one truss arranged at the center in the frontage direction. For example, the inner end 2A of the truss 2 is connected and supported by a truss fitting 10 attached to the building body M. In addition, since the outer end 2B is supported by the outer wall W of the partial one-story S, the pillar inside the outer wall W and below the truss is removed . As shown in FIG. 2, the basic truss 2 is represented by the number of blocks having one brace 6 as a basic unit.
It has a length that spans the block.

The basic truss 2 and other trusses 4 and the like constitute a roof by supporting a roof panel P via appropriate hardware. In addition, in this example, a king post truss or the like based on a triangle is used for each truss, but various trusses can be used according to the shape of the roof and the like.

As described above, the plate portion 3 includes the first plate 3A provided on the building body M side of the basic truss 2 and the second plate provided on the outer wall W side of the attached structure S. 3B .

In the present embodiment, the first plate 3A is shown in FIG.

In the present embodiment, the first plate 3A is attached with a screw N via a backing plate 13 that covers the lower truss chord 2U from above.

The diagonal dimension of the first plate 3A is:
It is larger than the width of the truss lower chord 2U. Thereby, the first plate 3A is formed so as to protrude on both sides of the truss, that is, on both sides of the truss lower chord 2U, and the mounting holes 14 are formed in the protruding portions.

Similarly, in the present embodiment, the second plate 3B has a substantially square shape as shown in FIG. 5, and one side thereof is along the truss lower chord 2U of the basic truss 2 so that It is fixed to the lower surface of the truss 2. Note that the second plate 3B is also attached with the screw N via the backing plate 13 similarly to the first plate 3A. The dimension of one side of the second plate 3B is larger than the width of the truss lower chord 2U so as to protrude on both sides of the truss lower chord 2U, and the protruding portions are respectively provided with a connecting material 5 described later.
And attachment holes 15 and 16 to which the brace 6 and the like are connected are appropriately formed.

The plate portion 3, the second plate 3B in this example, is located at a position between the blocks in the basic truss 2 having a length of two blocks, that is, at a position A where a column is conventionally provided. It is provided at a corresponding location.

In this embodiment, the second plate 3B
As shown in FIGS. 1 and 5, an end of a connecting member 5 which connects between the basic truss 2 and another truss 4 parallel to the basic truss 2 and is orthogonal to the basic truss 2 is applied to a backing plate. 13 and is connected by a screw N. The second plate 3B has the other end is also connected to one end of the brace 6 connected to the outer wall portion W.

As described above, in the present embodiment, the second truss 2 provided on the basic truss 2 is provided without providing a column inside the outer wall portion W.

As a result of the basic truss 2 having a length extending between two blocks, and connecting the inner end 2A to the building body side and connecting the outer end 2B to the outer wall W to support only both ends. Even without providing a pillar inside the outer wall portion W and below the truss, the outgoing dimension of the attached structure S can be set relatively large. The connecting member 5 can be made of various materials such as a shape steel material, a truss material, a beam material, and the like.

In this example, the other truss 4 is shorter than the basic truss 2 and is arranged on both sides of the basic truss 2. The other end of the connecting member 5 connecting to the truss 2 can be connected, and the ends of the outer connecting members 9 connecting the other truss 4 and the outer wall W of the attached structure S are also connected. doing.

The other truss 4 has the other end connected to the outer wall W of the attached structure S, and has one end receiving a truss-like first connecting member 7 orthogonal to the basic truss 2. It is connected to hardware 11. In the present embodiment, the connecting member 5 and the brace 6 are shown as being connected to the second plate 3B, but they may be provided separately on separate plates.

One end of a truss-like connecting member 7 orthogonal to the basic truss 2 is provided on the first plate 3A .
And, for example, the other end is connected to one end of the brace 6 connected to the outer wall W of the attached structure S.

In this example, the truss-like connecting member 7 is a truss, one end of which is connected to the first plate 3A, and the other end of which is an outer wall W parallel to the basic truss 2.
It is connected to. In the present embodiment, the brace 6 is connected to the second plate 3B, so that the truss-like connecting member 7 and the brace 6 are connected to the basic truss 2 using different plates. sell.

Thus, the first plate 3A has
For example, one end of a truss-like first tie member 7 whose outer end is supported by an outer wall portion W of the accessory structure S is connected to the second truss 2 and the second truss 2 is attached to the second plate 3B.
And a connecting member 5 connecting between the basic truss 2 and another truss 4 parallel to the basic truss 2 or orthogonal to a basic truss connecting directly between the basic truss 2 and the outer wall 4 parallel to the basic truss 2 A connecting member (not shown) and one end of a brace 6 whose other end is connected to the outer wall portion W of the attached structure S are connected.

As described above, the truss-like connecting member 5 connecting the trusses and the truss-like connecting members 5 as in the present embodiment using the plate portion 3 provided on the basic truss 2 without providing the pillar inside the outer wall portion W. Since the other end can be connected to the connecting member having the other end connected to the outer wall portion W, and the other end can be connected to one end of the brace 6 having the other end connected to the outer wall portion W, the structure of the roof frame can be simplified using a truss frame. In particular, the connecting member and the connecting portion of the brace 6 can be made simple.

Further, since the basic truss 2 can connect orthogonal trusses, even if there is no pillar inside the outer wall portion, the attached structure S having a relatively large size from the building body M can be obtained.
