However, in the roof structure described in Patent Document 1, the hut assembly member is provided at the upper part of the building skeleton, the outer beam portion constituting the outer shape of the building skeleton, and the inner beam portion provided inside the upper part of the building skeleton. Since it was designed to be attached to the intersection of each other, it was not possible to freely install the hut assembly members on the upper part of the building frame.

On the other hand, in Patent Documents 2 to 5, the roof panel is attached to the upper part of the building frame without using the hut assembly member as described above. For example, in Patent Document 2, a roof panel is installed using a large number of bundles, a large number of beams, and the like. In Patent Document 3, the roof panel is installed by using a large number of partition-shaped panels. In Patent Document 4, a large number of small roof units are used. In Patent Document 5, a large roof unit configured by using a large number of bundles or the like is used. Therefore, in all of Patent Documents 2 to 5, the installation structure of the roof panel is complicated. Moreover, in each case, the roof panel installation structure is easily restricted by the configuration of the building frame, so that there is not much freedom in the roof panel installation structure.

Therefore, the present invention mainly aims to solve the above-mentioned problems.

Then, as shown in FIG. 2A, the roof 3 has a hut assembly member 4 installed on the upper part of the building skeleton 2, and the roof panel 5 covers the upper part of the building skeleton 2 and the hut assembly member 4. It has a roof structure with ~ 7 (Fig. 1) installed.

In contrast to the above configuration, this embodiment has the following configuration.

(1) The hut assembly member 4 has a roof panel receiving portion 11 smaller than the outer shape of the upper part of the building frame 2, and a vertical member 12 extending downward from the corner portion of the roof panel receiving portion 11. At this time, the lower end portion of the vertical member 12 can be fixed to the intermediate portion of the inner beam portion 13 provided inside the upper part of the building frame 2.
A roof panel 5 located at the center is attached to the upper part of the roof panel receiving portion 11 of the hut assembly member 4 to form the roof top.
Further, the roof panels 6 and 7 located on the outside are diagonally attached between the edge of the roof panel receiving portion 11 and the outer beam portion 14 constituting the outer shape of the upper part of the building frame 2, and the roof outer portion (or the roof outer portion) (or It constitutes the outer periphery of the roof).

Here, the roof panel receiving portion 11 has at least a pair of parallel girder beams (panel receiving beams 11a) extending in the girder direction X (long direction) of the building frame 2. Between the pair of parallel panel receiving beams 11a, a plurality of ceiling joists extending in the end direction Y (short direction), a pair of parallel end beams (panel receiving beams 11b: FIG. 2A), and the like can be appropriately provided. .. The roof panel receiving portion 11 is formed to have a substantially rectangular shape in a plan view by the pair of parallel panel receiving beams 11a (girder beams) and the ceiling joists and the pair of parallel panel receiving beams 11b (wife beams). The vertical member 12 is a four pillar member extending in the vertical direction Z attached to the lower part of the four corners (corners or the positions of the ends of the receiving beams 11a) of the roof panel receiving portion 11. ing. It is preferable that the panel receiving beams 11a and 11b and the vertical member 12 are all made of a metal material. However, the panel receiving beams 11a and 11b and the vertical member 12 may be made of wood.

The upper part of the building frame 2 has an outer beam portion 14 constituting the outer shape and an inner beam portion 13 located inside the outer beam portion 14. The inner beam portion 13 includes all beam members other than the outer beam portion 14.

Although not adopted in this embodiment, the lower end portion of the vertical member 12 can be structurally fixed to the end portion of the inner beam portion 13, the outer beam portion 14, or the like.

The roof panel 5 located at the center may have any shape, for example, a quadrangular pyramid shape, but in this embodiment, the roof panel 5 is substantially horizontal and flat. As a result, the roof top becomes a horizontal flat roof.

The roof panels 6 and 7 located on the outside can be a triangular roof panel 6, a square roof panel 7, or the like in this embodiment. The triangular roof panel 6 and the square roof panel 7 form a trapezoidal roof surface 16 (FIG. 1). As a result, the roof 3 is surrounded by four trapezoidal roof surfaces 16 that are inclined around the horizontal flat roof surface. The seams between the trapezoidal roof surfaces 16 are ridges such as a descending ridge that slopes downward.

The triangular roof panels 6 are provided on both sides of the trapezoidal roof surface 16 to form a descending ridge. The triangular roof panel 6 is typical as a roof panel 6 having a hypotenuse that can form a descending ridge. However, the triangular roof panel 6 can be changed to a trapezoidal roof panel 6, another roof panel 6 having a hypotenuse, or the like. Hereinafter, the roof panel 6 will be described as a triangular roof panel 6 for the sake of clarity, but in short, the roof panel 6 having a hypotenuse for forming a descending ridge may be used. It is assumed that the roof panel 6 having another alternative shape as described above can also be included. Further, (E), (S), (W), and (N) attached to the trapezoidal roof surface 16 are approximate directions.

(2) As shown in FIGS. 3A to 3C, the roof panel 5 located at the center is a frame formed by connecting the ends of a plurality of parallel square members 21 with a pair of parallel beam receiving members 22. The face material 24 may be attached to the body 23.

Here, the diagonal member 31 is provided as a strength member for the roof 3 (roof reinforcing material). The diagonal member 31 is intended to ensure a horizontal proof stress against shaking such as an earthquake. It is preferable to use a metal material such as a square steel pipe for the diagonal member 31 so that the required strength can be obtained. However, if the required strength can be obtained, wood, a resin material, or the like can be used for the diagonal member 31. Further, as the diagonal member 31, a composite material or the like in which any two or more of wood, metal material and resin material are combined can also be used.

It is preferable that mounting brackets 32 and 33 for mounting on the upper portion of the cabin member 4 and the upper portion of the building frame 2 are previously installed at the upper end and the lower end of the diagonal member 31. As the mounting brackets 32 and 33, those having a shape and structure suitable for mounting on the upper part of the cabin member 4 or the upper part of the building frame 2 can be used. For example, the mounting bracket 32 at the upper end of the diagonal member 31 can be a U-shaped metal fitting (opened to the outside of the building frame 2) that extends in the vertical direction Z. Further, the mounting bracket 33 at the lower end of the diagonal member 31 can be a pair of left and right L-shaped metal fittings. The mounting brackets 32 and 33 are installed so that both side surfaces of the slanted lumber 31 are sandwiched between the upper and lower ends of the slanted lumber 31, and bolts and nuts can be rotated up and down with respect to the slanted lumber 31.

However, a bundle member 35 extending in the vertical direction Z is installed at the lower part of the roof panel receiving portion 11 at the position where the diagonal member 31 is attached, and the upper end portion of the diagonal member 31 is placed on the upper side surface of the bundle member 35. It is preferable to fasten and fix the mounting bracket 32 in the lateral direction with a fixture 36 such as a bolt or a nut. By installing the bundle member 35 in this way, the diagonal member 31 is supported by the roof panel receiving portion 11 (panel receiving beams 11a, 11b) at an arbitrary position in the intermediate portion of the hut assembly member 4. It will be possible to install it firmly.

Further, the mounting bracket 33 (horizontal plane) at the lower end of the diagonal member 31 is fastened and fixed to the upper surface of the outer beam portion 14 at the upper part of the building frame 2 in the vertical direction Z with a fixing tool 37 such as a bolt or a nut. ..

Such a structure is suitable for installing the diagonal member 31 at a position other than the joint between the adjacent roof panels 6 and 7 (see FIG. 1). For example, the building frame 2 has a wife direction Y (short direction). ), This is applied when installing the diagonal member 31 (slanting member 31a). Further, although not particularly shown, it can also be applied to the case where the slanted lumber 31 (diagonal lumber 31b: FIG. 1A) is installed toward the girder direction X (long direction) of the building frame 2.

At this time, it is preferable that the diagonal member 31 is provided at a position outside the cabin member 4. Further, it is preferable that the diagonal member 31 is arranged so as to be inclined substantially along the lower surface of the diagonal roof panels 6 and 7 located on the outside.

For example, a plurality of hut assembly members 4 can be arranged adjacent to each other in the wife direction Y (short direction) of the building frame 2. Further, although not particularly shown, a plurality of cabin members 4 may be arranged adjacent to the girder direction X (long direction) of the building frame 2.

The diagonal member 31 is the same as that of (3) described above, but when a plurality of shed assembly members 4 are arranged adjacent to each other, the mounting bracket 32 at the upper end of the diagonal member 31 is a T-shaped metal fitting 41 or the like. Is preferable. Then, the leg portion 41a of the T-shaped metal fitting 41 attached to the upper end portion of the diagonal member 31 is inserted so as to be sandwiched between the adjacent vertical members 12 of the adjacent hut assembly member 4, and together with the adjacent vertical members 12. The leg portion 41a is fastened and fixed laterally with a fixing tool 42 (or connecting tool) such as a bolt or a nut. This makes it possible to integrally connect the plurality of shed assembly members 4 and at the same time firmly fix the upper end portion of the diagonal member 31 to the shed assembly member 4 in a co-tightened state.

Such a structure is suitable for installing the diagonal member 31 at a position other than the joint between the adjacent roof panels 6 and 7 (see FIG. 1A). For example, the girder direction X (long length) of the building frame 2 is suitable. This is applied when the diagonal member 31 (slanting member 31b) is installed toward the direction). Further, although not particularly shown, it can also be applied to the case where the diagonal member 31 (slanting member 31a) is installed toward the wife direction Y (short direction) of the building frame 2.

At this time, it is preferable that the diagonal member 31 is provided at a position outside the cabin member 4. Further, it is preferable that the diagonal member 31 is arranged so as to be inclined substantially along the lower surface of the diagonal roof panels 6 and 7 located on the outside.

Of these, the steel-framed building unit 91 connects the upper ends of the four columns 82 in a rectangular shape with four ceiling beams, and connects the lower ends of the four columns 82 with four floor beams. It has a unit frame with a box rigid frame structure that is connected in a rectangular shape.

Then, the building frame 2 is constructed by arranging such a building unit 91 adjacent to the site at the construction site and stacking them vertically. In this embodiment, in the building frame 2, three large building units 91a are arranged side by side with respect to the wife direction Y, and three small building units 91b are arranged side by side with respect to the wife direction Y. It is assumed to have an almost rectangular shape in a plan view connected to 91a. The small building unit 91b may be replaced with a structure using eaves extension beams or the like. Further, for example, the width of the wife direction Y is half that of the large building unit 91a and the small building unit 91b arranged side by side with respect to the wife direction Y as shown in FIGS. 1 and 2. Building units 91c and 91d can be added to make the size as shown in FIGS. 1A and 2A.

In such a building frame 2, the ceiling beams of the building unit 91 on the uppermost floor are the above-mentioned inner beam portion 13 and outer beam portion 14. Further, the ceiling joists provided between the ceiling beams of the building unit 91 on the top floor can be used as an auxiliary beam member 13a (inner beam portion 13) for attaching the cabin member 4.

Then, the above-mentioned hut assembly member 4 is attached to the upper part of the plurality of building units 91 constituting the top floor of the building skeleton 2 so as to be located substantially in the center of the building skeleton 2. At this time, the cabin member 4 can be installed at a free position without considering the correspondence with the building unit 91. Further, the roof panels 6 and 7 can be installed relatively freely without considering the coincidence between the joints between the roof panels 6 and 7 and the joints between the building units 91.

<Action> The action of this example will be described below.

As shown in FIG. 2, the building skeleton 2 (upper floor portion) is assembled by a plurality of building units 91 and the like, and the hut assembly member 4 is installed in the central portion of the building skeleton 2 (upper floor portion).

At this time, at the factory, the fixing bracket (panel fixing bracket 51) on the water side of the panel fixing brackets 51 to 53 is attached to the upper part of the hut assembly member 4 in advance, and the building frame 2 (upper floor portion) is attached. The fixing brackets (panel fixing brackets 52, 53) on the eaves side of the panel fixing brackets 51 to 53 are attached to the upper part of the panel fixing bracket.

Then, the inclined roof surface 16 is constructed by attaching the triangular roof panel 6 and the square roof panel 7 using the panel fixing brackets 51 to 53 described above (FIG. 1). At this time, for example, the triangular roof panel 6 is attached first, and the square roof panel 7 is attached after the triangular roof panel 6.

First, the installation of the triangular roof panel 6 will be described. The triangular roof panel 6 has at least a vertical frame member 56.

Then, the support shaft portion 68 projecting in advance from the eaves side of the vertical frame member 56 constituting the triangular roof panel 6 is transferred to the guide portion 64 (guide groove portion) of the panel fixing brackets 52 and 53 on the eaves side. The eaves side of the triangular roof panel 6 is locked and held by the panel fixing brackets 52 and 53 on the eaves side so as to be dropped from above (FIG. 7A).

At the same time, the upper portion of the triangular roof panel 6 is placed on the panel receiving portion 57 (triangular receiving surface 57a) of the panel fixing bracket 51 on the water side (FIG. 6).

Then, the upper end portion of the vertical frame member 56 constituting the triangular roof panel 6 and the panel fixing portion 58 (panel fixing portion 58a) on the side surface of the panel receiving portion 57 (receiving surface 57a) are fastened with bolts and nuts. Fix with a tool. After that, nuts 68a and the like are screwed to the support shaft portion 68 projecting from the eaves side of the vertical frame member 56 constituting the triangular roof panel 6, and the vertical frame members are attached to the panel fixing brackets 52 and 53 on the eaves side. The eaves of 56 are fastened and fixed. At this time, a joint metal fitting 69 is installed inside the panel fixing portion 63 of the panel fixing metal fittings 52 and 53, and a fixing tool such as a bolt or a nut is provided between the joint metal fitting 69 and the flange portions 63b and 63c of the panel fixing portion 63. It may be fixed at 70.

After the triangular roof panel 6 is attached in this way, the inclined roof surface 16 is constructed by attaching the square roof panel 7 in substantially the same procedure as described above. Further, a horizontal roof surface 16 is attached to the upper surface of the cabin member 4. As a result, the roof 3 described above is completed.

<Effect> According to this embodiment, the following effects can be obtained.

(Effect 1) It is assumed that the roof panels 6 and 7 are installed so as to cover the upper part of the building frame 2 and the hut assembly member 4 in the roof structure. As a result, the roof 3 can be easily constructed by arranging the roof panels 6 and 7 using the upper part of the building frame 2 and the hut assembly member 4. Further, since only one cabin member 4 is required, the support structure of the roof panels 6 and 7 can be simplified. Further, since it is only necessary to install at least one cabin member 4 for the roof panels 6 and 7 and the building frame 2, the number of objects to be installed in the cabin back space can be minimized.

At this time, the hut assembly member 4 is assumed to have a roof panel receiving portion 11 smaller than the outer shape of the upper part of the building frame 2 and a vertical member 12 extending downward from the corner portion of the roof panel receiving portion 11. No. 12 has a lower end portion that can be fixed to an intermediate portion of the inner beam portion 13 at the upper part of the building frame 2. As a result, regardless of the configuration of the building skeleton 2, the hut assembly member 4 can be freely installed on the upper part of the building skeleton 2. Therefore, the degree of freedom for the roof structure and the roof 3 can be increased.

Then, the roof top is composed of the central roof panel 5 attached to the upper part of the roof panel receiving portion 11 of the hut assembly member 4, and the roof outer portion is formed by the edge of the roof panel receiving portion 11 and the upper part of the building frame 2. It may be configured by diagonal roof panels 6 and 7 located on the outside attached between the outer beam portion 14 constituting the outer shape. As a result, the roof 3 can be finished into a good-looking roof 3 having a relatively large area roof surface 16 with a simple appearance. Further, by having five roof surfaces (roof panel 5 and roof surface 16) composed of roof panels 5 to 7, the roof 3 can be made high in strength.

(Effect 2) The face material 24 is attached to the frame body 23 formed by connecting the roof panel 5 located at the center between the ends of a plurality of parallel square timbers 21 with a pair of parallel beam receiving members 22. It may be pasted. As a result, the roof panel 5 located at the center can be made to have a simple structure and high strength. As a result, it is possible to eliminate the need to support the roof panel 5 located at the center by providing a support member such as a pillar on the lower side of the roof panel 5 located at the center.

Further, by making the roof panel 5 located at the center substantially horizontal and flat, the roof panel 5 located at the center can be made stronger.

(Effect 3) The upper part of the hut assembly member 4 and the upper part of the building frame 2 may be connected by a diagonal member 31. As a result, the diagonal member 31 which is the strength member of the roof 3 can be structurally and reasonably installed. Therefore, for example, the roof 3 can be provided with a horizontal bearing capacity against shaking such as an earthquake by the diagonal member 31.

In particular, by installing the slanted lumber 31 in both the girder direction X and the wife direction Y of the building frame 2, the roof 3 can secure the horizontal bearing capacity against shaking in various directions. Since the diagonal member 31 can be installed at a position other than the joint between the adjacent roof panels 6 and 7 (see FIG. 1), the roof panels 6 and 7 can be freely divided.

At this time, if the diagonal member 31 is provided at a position outside the cabin assembly member 4, it is possible to secure a space without the diagonal member 31 inside the cabin assembly member 4. Further, if the diagonal member 31 provided at the position outside the cabin member 4 is arranged so as to substantially follow the lower surface of the diagonal roof panels 6 and 7 located on the outside, the exterior of the cabin member 4 and the cabin assembly can be arranged. It is possible to install the diagonal member 31 (on the back of the cabin) so as not to interfere with the boundary portion between the inside and the outside of the member 4.

(Effect 4) The diagonal member 31 may be provided at a position between a plurality of cabin members 4. As a result, the diagonal member 31 can be efficiently provided by utilizing the connecting portion between the adjacent hut assembly members 4. At this time, if the diagonal member 31 having the upper end portion sandwiched between the cabin assembly members 4 is installed toward the outside of the cabin assembly member 4, there is no diagonal member 31 inside between the adjacent cabin assembly members 4. It becomes possible to secure a space. Further, if the diagonal member 31 provided at the position outside the cabin member 4 is arranged so as to substantially follow the lower surface of the diagonal roof panels 6 and 7 located on the outside, the exterior of the cabin member 4 and the cabin assembly can be arranged. It is possible to install the diagonal member 31 (on the back of the cabin) so as not to interfere with the boundary portion between the inside and the outside of the member 4.

(Effect 5) The diagonal roof panels 6 and 7 located on the outside may be fixed to the cabin member 4 with the panel fixing bracket 51. As a result, the fixing strength of the diagonal roof panels 6 and 7 located on the outside to the cabin member 4 can be secured and improved by the panel fixing bracket 51. Therefore, it is possible to give the diagonal roof panels 6 and 7 located on the outside a function of bearing the same horizontal force as the diagonal member 31 as a strength member. Further, if the panel fixing bracket 51 is attached to the cabin member 4 in advance, the diagonal roof panels 6 and 7 located outside the cabin member 4 can be easily attached at the site.

Similarly, the diagonal roof panels 6 and 7 located on the outside may be fixed to the upper part of the building frame 2 by the panel fixing brackets 52 and 53. As a result, the same effect as that of the panel fixing bracket 51 can be obtained. Further, for example, in a ridge portion (downward ridge) formed at a joint between triangular roof panels 6 on a trapezoidal roof surface 16 adjacent to each other, the relationship with the roof panel 5 located in the center is adjusted to form a ridge. The length of the ridge can be optimally set so that the ridge does not become too long, and the required strength can be secured by combining the triangular roof panels 6 together. It is possible to eliminate the need to provide a bundle or the like. The vertical frame material and the horizontal frame material constituting the triangular roof panel 6 and the square roof panel 7 are made of wood, metal material, resin material, wood and metal material according to the required strength. A composite material or the like in which any two or more of the resin materials are combined can be appropriately used.

(Effect 6) The diagonal roof panels 6 and 7 located on the outside, the hut assembly member 4, and the upper part of the building frame 2 form the truss structure portion 81 at the position outside the hut assembly member 4. Is also good. Since the truss structure 81 can bear the horizontal force, for example, the roof 3 can have a horizontal force against shaking such as an earthquake.

Further, by providing the truss structure portion 81 (using the diagonal roof panels 6 and 7 located on the outside) at the position outside the cabin assembly member 4, the interior of the cabin assembly member 4 is particularly inclined. Since it is not necessary to provide reinforcing means such as materials, it is possible to secure a large space inside the cabin member 4. Therefore, for example, a large space behind the cabin can be provided inside the cabin member 4.

(Effect 7) The roof panel 5 located at the center and the cabin member 4 may be fixed by the bolt fixing portion 85. As a result, the roof panel 5 located at the center can be easily and firmly installed on the cabin member 4.

(Effect 8) The roof panel 5 located in the center and the diagonal roof panels 6 and 7 located on the outside may be connected via the hut assembly member 4. This makes it possible to separately install the roof panel 5 located in the center and the diagonal roof panels 6 and 7 located on the outside with respect to the cabin member 4. Therefore, the workability of the roof 3 can be improved.

(Effect 9) By providing the roof structure, the building 1 can obtain the same effect as the roof structure. Further, when the building 1 is a unit building, the building units 91 constituting the unit building and the roof panels 5 to 7 do not have to match the size in particular, or the roof panels 5 to 7 are used as a building. Since it is not necessary to make the size suitable for the unit 91, the size of the roof 3 can be optimally adjusted to give a good appearance. Moreover, since the roof panels 5 to 7 can be divided into, for example, a size and a number of roof panels 5 to 7 that are even on the left and right and well-balanced, it is possible to reduce the labor and cost of production, transportation, and the like of the roof panels 5 to 7. can.
