Description

The present invention relates to a roof structure (koyagumi) of a wooden framed building.

A typical koyagumi consists of building a bundle of huts on a beam of a hut, arranging purlins and purlins, and arranging rafters on top of it.

However, the workability is not good because each member is assembled one by one. For this reason, the members are made into panels.

For example, Patent Document 1 below discloses a chevron frame fixed on a hut beam. The chevron frame has a land beam portion extending horizontally inward from the lower ends of a pair of left and right inclined portions inclined with respect to the horizontal, and this land beam portion is bolted to the hut beam. A plurality of such chevron frames are arranged in parallel, and are connected to each other by a connecting member or a brace with a turnbuckle. After that, after arranging the purlins on the Yamagata frame, put up a field board and roof the roofing material on it.

Japanese Unexamined Patent Publication No. 2006-200166

In the configuration of Patent Document 1, maintenance of the arrangement form between the chevron frames must rely on a connecting member or the like, and work for fixing these must be performed separately.

Further, although the chevron frame is fixed on the hut beam, the pillars provided on the land beam portion and connected to the frame body are thinner than the pillar material of the skeleton. In other words, the koyagumi using the Yamagata frame can only be placed on the skeleton, and its structural integrity with the skeleton is low.

Therefore, it is a main object of the present invention to further improve workability and to enable good load support.

The means for that is a roof structure that is fixed on a skeleton having a shaft member of a wooden frame structure, and a hut panel that is fixed upright in the plane direction and a roof panel that is placed on the hut panel. Each panel has a frame that forms the contour of the panel and a support material that is vertically and horizontally assembled inside the frame, and at least a part of the support material corresponds to the cross section of the shaft material. A panel shaft material having a cross section is arranged, and the panel shaft material is configured to hold a shaft material or a metal joint to be used for joining another shaft material corresponding to the shaft material, and the shaft material of the skeleton. It is a configuration in which the panel shaft material of each panel is joined in association with.

In this configuration, if the hut panel is fixed and then the roof panel is fixed, a hut assembly can be obtained. By joining the panel shaft material of the hut panel to the shaft material of the skeleton and joining the panel shaft material of the roof panel to the panel shaft material of the hut panel, high joint strength and integrity can be obtained.

According to the present invention, the shed assembly can be obtained by fixing the shed panel and the roof panel, so that the workability is good. Moreover, each panel has a panel shaft material, and these can be directly or indirectly joined to the shaft material of the skeleton to obtain high integrity, so that the load can be well supported.

An embodiment for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view showing an outline of a roof structure (hut structure) 11 using a virtual line in part. The roof structure 11 fixed on the skeleton 13 having the shaft member A of the wooden frame structure is placed on the hut panel 14 fixed in the plane direction on the skeleton 13 and the hut panel 14. It is composed of a roof panel 15. That is, the cabin panel 14 and the roof panel 15 each form a part of the roof structure 11. In FIG. 1, the roof panel 15 is shown by a virtual line for convenience.

In this example, a one-way roof is shown for simplification of the description, but the roof structure 11 may be a roof of another form.

The skeleton 13 to which the roof structure 11 is fixed is intended to simplify the construction as in the roof structure 11, and is configured by assembling the outer wall panel 16 and the partition panel 17. The outer wall panel 16 and the partition panel 17 are vertically and horizontally assembled with a shaft material A for supporting a load, that is, a pillar material, a beam material, and other wire materials.

As shown in FIG. 2, the hut panel 14 constituting the roof structure 11 is roughly divided into two types. Each of these cabin panels 14 includes a frame 31 that forms the contour of the cabin panel 14, and a support member 32 that is vertically and horizontally assembled inside the frame 31.

The two types of cabin panels 14 are a rectangular cabin panel 14a and a triangular cabin panel 14b. The rectangular hut panel 14a is a rectangular hut panel 14 fixed to the side corresponding to the girder in the skeleton 13, and the triangular hut panel 14b is fixed at a right angle to the rectangular hut panel 14a and is fixed from the girder side to the eaves girder side. It is a triangular hut panel 14 that descends diagonally toward.

In any of the cabin panels 14, at least a part of the support members 32 uses the panel shaft member S having a cross section corresponding to the cross section of the shaft member A of the skeleton 13.

Further, at least a part of the required frame 31, a panel shaft member S having a cross section corresponding to the cross section of the shaft member A of the skeleton 13 is used.

Here, the "cross section corresponding to the cross section of the shaft member" means that the shape and size of the cross section of the panel shaft member S are the same as those of the cross section of the shaft member A in the skeleton 13, or similar ones. It means that the size is larger than that, and the value of either one of the vertical cross-sectional lengths is the same, and the load can be supported in the same manner as the shaft member A of the skeleton 13. The cross-sectional shape of the shaft member A in the skeleton 13 of this example is a square. All or part of the shaft member A or the panel shaft member S may have other cross-sectional shapes.

All or part of the panel shaft member S in the cabin panel 14 is arranged at positions corresponding to the shaft member A of the frame 13 at the time of assembly.

Specifically, the frame 31 of the rectangular hut panel 14a has a lower side 31a extending horizontally to form a lower contour, an upper side 31b extending in parallel with the upper side 31b to form an upper contour, and one end on the left and right extending vertically. It has one end side 31c constituting the above and the other end side 31d forming the other end in parallel with the one end side 31c. Of these, the upper side 31b and the other end side 31d are made of the panel shaft member S, and the lower side 31a and the one end side 31c are made of the frame material T.

The frame material T is a material thinner than the panel shaft material S, and its cross-sectional shape is rectangular, its long side is the same as the side of the cross-sectional shape of the panel shaft material S, and its short side is shorter than that.

The panel shaft member S is used for the upper side 31b in order to secure the strength and prepare for fixing the roof panel 15. The reason why the panel shaft member S is used for the left and right other end sides 31d is to secure the strength and to prepare for the fixing to the skeleton 13 and the fixing of the roof panel 15.

Reinforcing panels 41 of right-angled isosceles triangles are fixed to the four inner corners of the frame 31 to provide an accurate right angle, and to restrain the panel shaft member S and the frame member T constituting the corners.

In this example, the support material 32 is provided only with a vertically extending material. The support member 32 is spread between the upper side 31b and the lower side 31a of the frame 31, and is arranged in parallel along the left-right direction. Among the support members 32, the support member 32 at the portion corresponding to the shaft member A of the skeleton 13 is the panel shaft member S. The other support material 32 is the frame material T described above.

The frame member T constituting the frame 31 and the support member 32 is assembled so that the surface adjacent to the side surface of the panel shaft member S is flush with the side surface. That is, the long side of the cross-sectional shape of the frame member T is fixed in the thickness direction of the rectangular shed panel 14a.

The frame 31 of the triangular hut panel 14b is a right triangle, and has a lower side 31e extending horizontally to form a lower contour, a vertical side 31f extending upward at a right angle at one end of the lower side, and an upper end and a lower side of the vertical side 31f. It has a hypotenuse 31g connecting the other ends of 31e. All of these sides 31e, 31f, 31g are made of the frame material T.

Basically, the frame 31 of the triangular hut panel 14b may be composed of only the frame material T. However, on the vertical side 31f of the triangular hut panel 14b in which the panel shaft member S does not exist at the assembly portion of the rectangular hut panel 14a, the panel shaft member S is like the triangular hut panel 14b shown at the right end of the drawing in FIG. Is attached to the frame material T on the vertical side 31f as a part of the frame 31. Further, the hypotenuse 31 g of the frame 31 may be made of the panel shaft member S in preparation for fixing the roof panel 15 or the like. In this way, whether or where the panel shaft member S is used for a part of the frame 31 is set in relation to the skeleton 13, the roof panel 15, and the like.

The support member 32 includes a vertically extending one and a supporting member 32 extending horizontally from the middle of the vertical side 31f in the longitudinal direction toward the middle of the hypotenuse 31g. Of the support members 32, the 11 support members 32 extending horizontally and the support member 32 extending vertically at the tip position of the support member 32 are the panel shaft members S. The support member 32 extending vertically from the panel shaft member S is provided at a position corresponding to the shaft member A of the skeleton 13. The other support material 32 is made of the above-mentioned frame material T.

The panel shaft member S extending to the side is provided in order to secure strength and to prepare for fixing to the rectangular hut panel 14a. The reason why the panel shaft member S extending vertically is provided is to secure the strength and to prepare for the fixing to the skeleton 13 and the fixing of the roof panel 15.

The support member 32 made of the frame material T is between the frame material T constituting the lower side 31e and the panel shaft material S extending laterally, and between the panel shaft material S extending laterally and the frame material T constituting the hypotenuse 31 g. , Extends between the frame material T constituting the lower side 31e and the frame material T constituting the hypotenuse 31g.

Also in the triangular hut panel 14b, the frame material T constituting the frame 31 and the support material 32 has a long side having a cross-sectional shape so that the surface adjacent to the side surface of the panel shaft material S is flush with the side surface. Is fixed in the thickness direction of the triangular hut panel 14b.

The roof panel 15 is obliquely fixed on the shed panel 14 assembled as shown in FIG. The structure of the roof panel 15 is the same as that of the cabin panel 14 described above. That is, it includes a frame 51 that forms the contour of the roof panel 15, and a support member 52 that is vertically and horizontally assembled inside the frame 51. A panel shaft member S having a cross section corresponding to the cross section of the shaft member A of the skeleton 13 is used for at least a part of the support member 52. All or part of the panel shaft member S is arranged at positions corresponding to the shaft member A of the skeleton 13 at the time of assembly, in the same manner as described above.

Further, the roof panel 15 has a structure that can be divided into a plurality of roof panel carriers 15a to 15f. That is, the roof panel 15 is formed by combining the plurality of roof panel carriers 15a to 15f.

Specifically, the roof panel 15 is rectangular, and the frame 51 has an upper side 51a, a lower side 51b, and end sides 51c and 51d at both left and right ends, and all of these sides 51a to 51d are composed of the frame material T. ing. The support member 52 includes one extending vertically from the girder side toward the eaves girder side and one extending in the horizontal direction orthogonal to the support member 52. Of the vertically extending support members 52, the support member 52 arranged at a position corresponding to the shaft member A and the triangular hut panel 14b of the skeleton 13 and an appropriate position between them is composed of the panel shaft member S. To. The support member 52 extending vertically from the panel shaft member S is referred to as a rafter shaft member 52a. Further, among the support members 52 extending horizontally, the support member 52 arranged at the position corresponding to the shaft member A of the skeleton 13 and the rectangular hut panel 14a is composed of the panel shaft member S. The support member 52 which is composed of the panel shaft member S and extends in the horizontal direction, that is, in the direction of connecting the rafter shaft members 52a to each other, is referred to as a connecting shaft member 52b. The other support material 52 is composed of the frame material T.

A part of the support member 52 is made of the panel shaft member S in order to secure the rigidity and prepare for fixing to the cabin panel 14 and the skeleton 13.

Among the support members 52 extending vertically from the panel shaft member S, the support member 52 made of the panel shaft member S other than the positions corresponding to the shaft member A of the skeleton 13 and the triangular hut panel 14 considers the following points. Is arranged. That is, since the roof panel 15 is composed of a plurality of roof panel carriers 15a to 15f, the roof panel carriers 15a to 15f are not only rigid so that the roof panel carriers 15a to 15f have at least one rafter shaft member 52a. The position and number of the support members 52 made of the panel shaft member S are set in consideration of the size of the support member 52.

A support member 52 made of a frame member T is disposed at a portion of the roof panel carriers 15a to 15f adjacent to each other in contact with the rafter shaft member 52a made of the panel shaft member S. Therefore, the roof panel carriers 15a to 15f include those having a rafter shaft member 52a at one end in the left-right direction and those having a rafter shaft member 52a at both ends. Therefore, the connecting shaft member 52b exists so as to directly or indirectly connect the rafter shaft members 52a to each other.

Of the roof panel carriers 15a to 15f, the frame members T constituting the left and right end sides 51c and 51d of the frame 51 are separated from the roof panel carriers 15a and 15f located at both ends by appropriate overhang lengths. It is fixed integrally.

Further, the reinforcing panel 41 is fixed at an appropriate position in the corner portion composed of the rafter shaft member 52a and the connecting shaft member 52b, as in the case of the rectangular shed panel 14a described above.

Also in the roof panel 15, the frame material T constituting the frame 51 and the support material 52 has a long side having a cross-sectional shape so that the surface adjacent to the side surface of the panel shaft material S is flush with the side surface. It is fixed in the thickness direction of the roof panel 15.

The panel shaft member S of the cabin panel 14 and the roof panel 15 is joined to the shaft member A of the skeleton 13 or another shaft member corresponding to the shaft member A, here, to be joined to the panel shaft member S. The hardware 71 is held (see FIGS. 4 to 6).

The metal joint 71 has a panel shaft material in which the metal joint 71 is held, as well as a shaft material other than the panel having the panel shaft material S in which the metal joint 71 is held. It is also used for panel assembly. Further, the joining metal fitting 71 is not only joined by directly applying a fastening force, but also joined by maintaining a certain positional relationship by insertion or the like.

The joining metal fitting 71 of this example has a fastening structure using bolts and nuts, and is made of an appropriate metal fitting. Since it has a fastening structure using bolts and nuts, the members to be joined can be joined and separated.
