Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hut structure which is used for a roof (including a directional roof), and which is suitably used particularly in a region with a large amount of snow.

[0002]

2. Description of the Related Art In general, a panel construction method is known in which a house is constructed by installing panels manufactured in advance at a factory or the like on floors, walls, roofs, and the like at a construction site. In a house of the above-mentioned panel method, floors, walls, roofs, etc. are joined together to form a house, so basically, columns and beams are almost not used.
Since it is difficult to support all the roof panels constituting the roof only with the wall panels, beams for supporting the roof are used.

A roof support beam for supporting a lower surface of a ridge roof (including a square roof) or the like provided in a panel construction house is disclosed in, for example, Japanese Patent Application Laid-Open No. 8-74370. A so-called bent beam is used.

[0004] In the hut structure using the bent beam, at least a part of the inner wall of the house is provided so as to reach the back side of the roof, and the upper end of the inner wall is joined to the roof. Also, a plurality of vent beams are supported by joining the end of the climbing portion of the vent beam to the upper end of the outer wall, and joining the end of the horizontal portion to the upper end of the inner wall to support the entire roof. A hut structure is formed. Therefore, since there is no beam or bundle supporting the bent beam below the vent beam arranged along the back side of the roof, the space behind the roof at the back of the roof can be made relatively large, and the ceiling can be installed. By increasing the height or providing a room for storing a large cabin behind the hut, the hut back space can be effectively used.

[0005]

However, the above-mentioned hut structure has an inner wall provided to support the roof and the vent beam so as to reach the roof.
For example, the use of the attic space is limited, for example, the attic of the house is completely covered by the inner wall, and a single attic space consisting of the entire attic cannot be constructed.

Further, as described above, in a hut back structure using an inner wall, even if the roof has a similar shape, the position of the inner wall differs depending on the layout under the roof, and it is necessary to change the hut structure depending on the position of the inner wall. . That is, even if the roof has the same shape, the hut structure cannot be made the same, and the hut structure is determined by the position of the inner wall. For example, designing an optimal hut structure in terms of cost Was difficult.

On the other hand, in an area with a large amount of snow, the strength of the roof needs to be higher than that in an area with a small amount of snow in order to support a large load applied to the roof by the weight of the snow. When the hut structure is applied to an area with a large amount of snow, it is necessary to increase its strength.

[0008] For these reasons, there is a demand for a hut assembly structure that can use the entire attic as a single attic space and can be applied to an area with a large amount of snow.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a cabin having a structural strength sufficient to obtain a large cabin back space by an easy construction work and to sufficiently bear the weight of snow. It is intended to provide a braided structure.

[0010]

In order to solve the above-mentioned problems, the invention according to claim 1 is, for example, as shown in FIG. Has four roof surfaces 7 flowing from the center in all directions,
A hut structure that supports a roof in which the boundary between the roof surfaces 7 except for the ridge is a corner ridge 10, and a lower end portion of one of the four roof surfaces 7 on the back side of the roof. From the side of the roof surface 7 obliquely upward along the inclination direction of the roof surface 7
Climbing portions 13 and 23 reaching one of the left and right corner ridges 10 and the roof surface 7 adjacent to the roof surface 7 from an end of the corner ridge 10 portion of the climbing portions 13 and 23. It has vent beams 1 and 2 provided with horizontal portions 12 and 22 extending horizontally so as to be orthogonal to the inclination direction, and the vent beams 1 and 2 passing through the same corner building 10 form a set of two or more vent beams. One set is arranged for each corner ridge 10, and the ends of the bent beams 1, 2 on the side of the horizontal parts 12, 22 are disposed on the roof surface 7 on which the horizontal parts 12, 22 are disposed, and the climbing part 13 is disposed. Another vented beam 1
Characterized by being joined at right angles to one of them.

According to the first aspect of the present invention, the bent beams 1 and 2 passing through the same corner ridge 10 in the hut assembly structure are arranged as at least two pairs, one for each corner ridge 10, and The ends of the bent beams 1 and 2 on the side of the horizontal portions 12 and 22 are at right angles to one of the other bent beams 1 on which the climbing portion 13 is disposed on the roof surface 7 on which the horizontal portions 12 and 22 are disposed. By joining to the roof, a large cabin back space can be obtained with easy construction work, and a hut structure with enough structural strength to withstand the large load applied to the roof due to the weight of snow can be constructed. .

That is, in the present invention, since two or more horizontal parts 12, 22 of two or more vent beams 1, 2 are arranged on each roof surface 7, each roof surface 7 basically has two or more vent beams. 1,
The second horizontal portions 12 and 22 and the outer wall 50 support the second horizontal portions 12 and 22, thereby improving strength. Further, in the cabin structure of the present invention, the horizontal portion 1 of each of the vent beams 1 and 2 is provided.
The horizontal portions 12 and 22 of the vent beams 1 and 2 are connected to their own climbing portions 13 and
23 and the climbing portion 13 of the other vent beam 1. Therefore, there is no need to extend the inner wall up to the back of the roof to support the roof or beams,
With a roof of almost the same shape, we can share the roof structure and add strength to withstand a lot of snow,
A large attic space can be obtained. Also, the hut structure can be determined regardless of the position of the inner wall. Furthermore, this makes it possible to reduce the cost by making the hut assembly structure a symmetrical structure and sharing the beams of the hut assembly as much as possible.

The hut structure of the present invention basically supports a roof panel for a panel construction method, and a rafter is not attached to each bent beam. If the rafters are to be attached, not only the house using the roof panel for the panel construction method, but also the frame construction method constructed by attaching the face plate constituting the roof surface on the rafter without using the roof panel for the panel construction method It can also be applied to roofs. In addition, the frame other than the roof is not limited to wooden,
It is also applicable to steel frames and reinforced concrete structures.

According to a second aspect of the present invention, in the cabin assembly structure according to the first aspect, the first bent beam 1 in which the horizontal portion 12 of the pair of bent beams 1 and 2 is disposed at the highest position. The horizontal portion 12 side end portion has the roof surface 7 on which the horizontal portion 12 is disposed and the horizontal portion 12 of the first vent beam 1 of another set in which the climbing portion 13 is disposed on the roof surface 7. Roof surface 7
The first vent beam 1 of the other group in the corner building 10
And the horizontal portions 12 of the four first vent beams 1 are arranged in a rectangular frame shape, and the horizontal portion 22 of the pair of vent beams 1 and 2 is located at a position lower than the first vent beam 1. The end of the second vent beam 2 to be arranged on the horizontal portion 22 side is joined to the climbing portion 13 of the other set of the first vent beam 1 and the horizontal portion 22 of the second vent beam 2 From the vicinity of the side end to the horizontal portion 2
The extension beam 3 is arranged so as to extend the extension beam 2, and the tip end of the extension beam 3 is connected to the roof surface 7 on which the extension beam 3 is arranged and another roof surface on which the climbing portion 23 is arranged. Four second vents are joined to the second vent beam 2 of the other set at the corner ridge 10 at the border with the roof surface 7 where the horizontal portion 22 of the second vent beam 2 of the set is disposed. The horizontal beam 22 and the extension beam 3 of the beam 2 are arranged in a square frame shape.

According to the second aspect of the present invention, the bent beams 1 and 2 are arranged in double (or triple or more), and the extension beam 3 extending the end of the outer second bent beam 2 is provided.
Are used to form two rectangular frame-shaped structures. Thereby, the strength can be improved together with the double bent beams 1 and 2, and the end of the horizontal portion 22 of the second bent beam 2 on the distal end side is extended to the extension beam 3. By reaching the corner ridge 10, it is possible to improve the workability such as easy arrangement of the roof panel on the hut combination.

For example, when installing a roof panel supported by the hut structure, the horizontal portion 12 of the first vent beam 1 and the horizontal portion 22 or the extension beam 3 of the second vent beam 2 are installed. A roof panel whose upper and lower ends are supported, a horizontal portion 22 or an extension beam 3 of the second vent beam 2 and an outer wall 5
In addition, the arrangement of the roof panel supporting the upper and lower ends at 0 has the effect of shortening the span of the roof panel, and has a structure capable of sufficiently withstanding a large load applied to the roof due to the weight of snow. A hut structure with strength can be constructed.

The horizontal portion 12 of the first vent beam 1
In the case of employing a method of arranging a roof panel that supports the top and bottom of the roof panel with the outer wall 50 and the outer wall 50, the horizontal portion 22 of the second vent beam 2 and the horizontal portion 12 of the first vent beam 1 and the outer wall 50 are used. By separating the spaces at substantially equal intervals, the second vent beam 2 functions as a roof panel support member, and has substantially the same effect as shortening the span of the roof panel. By this effect, it is possible to construct a hut structure having structural strength enough to withstand a large load applied to the roof due to the weight of snow. In a portion above the horizontal portion 12 of the first vent beam 1, for example, the roof panel is assembled in a tent shape so that the lower portion of the roof panel is supported by the horizontal portion of the first vent beam, Are in a state where they are supported by each other. Also, in the case where the roof is composed of the rafters and the surface materials without using the roof panel, the rafters are also formed by the horizontal portion 12

Thus, the span of the roof panel whose upper and lower ends are supported can be made substantially equal, and the strength can be almost uniformly increased on the roof surface 7. In addition, since the roof panel whose upper and lower ends are supported by the second vent beam 2 and the outer wall 50 usually has an eave outside the outer wall 50, the first vent beam 1 and the second Although the length is longer than the roof panels supported at both upper and lower ends by the vent beam 2, the distance between the supports (the first and second vent beams and the outer wall) supporting these roof panels is substantially equal. Even when the number of the second vent beams 2 is two or more, the span of each roof panel is substantially equalized by each of the vent beams 1 and 2 and the outer wall 50.

Also, when the roof panel is arranged so as to bridge between the first vent beam 1 and the outer wall 50, the second panel is so arranged as to evenly partition the first vent beam 1 and the outer wall 50. By disposing the vent beam 2 of the first embodiment, the space between the first vent beam 1 of the roof panel and the outer wall 50 can be evenly supported.
