Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a building or half-gable roof with a simple structure by installing a building material having an inclined portion fixed to one end of a building portion passing through a main building on an inner and outer bundle material. Regarding the structure of the building that can be formed.

[0002]

2. Description of the Related Art Houses of a panel construction method are widely used in which a panel structure such as a roof panel or a wall panel is arranged on a frame structure using a steel frame structure to form a roof or a wall of the house.

Further, such a house has a main building which forms a ridgeline of the roof and a ridge-shaped roof having a pair of descending buildings extending from the end of the main building to the eaves corners of the house in a H-shape. On the other hand, a semi-gable roof is often used in which the alighting ridge is interrupted by an eave near the gable roof that extends obliquely upward from the eaves corner portion in the wife direction.

Further, such a roof structure of a hipped roof or a half-gabled roof includes, for example, a ridge member along the main ridge, a climbing beam member along a descending ridge, and a climbing beam that is orthogonal to the eaves and is connected to the climbing beam member. Further, it is formed by using a frame material such as a purlin that horizontally connects the climbing beams.

[0005]

In such a roof set, the end of the building material and the upper end of the climbing beam are conventionally erected by a bundle material at the intersection of the end portions of the building material by the bundle material. , Was attached by supporting the upper ends of the climbing beams, respectively,
Such attachment of the bundle material increases the number of work steps, and there is a case where the bundle material cannot be erected depending on the arrangement of the beam members below, and improvement thereof has been desired.

Further, there is a large gap in the structure between the roof set forming the hipped roof and the roof set forming the half gable roof, and the structure of the new structure that can form both of them from the same basic roof set. The appearance was strongly requested.

According to the present invention, a building material in which one end of a downwardly inclined portion inclined by the flow gradient of the triangular roof portion between the descending buildings is fixed to one end of the building portion passing through the main building is installed on the inner and outer bundle materials. Based on pre-installing a mounting piece for bolting the climbing beam material to one end of the inclined portion, it is possible to conveniently join the building material and the climbing beam material without using a bundle material, and The purpose is to provide a building structure that allows construction of a half-gable roof with a simple structure.

[0008]

SUMMARY OF THE INVENTION According to the present invention, a main building has a descending wing that opens in a V shape and extends downward at one end of the main building between the main roof and the descending building on both sides of the main building. A structure of a dormitory having a triangular roof portion or a building forming a half-gabled roof, the downward sloping portion being inclined at the flow gradient of the triangular roof portion at one end of the ridge portion made of shaped steel and passing through the main ridge. An outer bundle material that is fixed to one end of the ridge member by bolts to the other end of the inclined portion and is arranged at both ends of the joint material in a direction orthogonal to the flow gradient of the triangular roof portion, and the other end of the ridge portion. In addition to erection with the inner bundle arranged at the end of the sloped portion, a mounting piece for bolting the climbing beam extending to the outer bundle along the alighting ridge is pre-installed at one end and both side surfaces of the inclined portion. There is.

[0009]

[Function] The building material is such that one end of a downward sloped part that is inclined by the flow gradient of the triangular roof part is fixed to one end of the ridge part that passes through the main building, and the other end of the sloped part has a flow gradient of the triangular roof part. The joint material in the right angle is bolted. An outer bundle is arranged at both ends of the joint material, and the ridge is constructed by the outer bundle and the inner bundle arranged at the other end of the ridge. Further, the upper end of the climbing beam member extending to the outer bundle member along the descending ridge is fixed by bolting to mounting pieces that are pre-welded to one end and both side surfaces of the inclined portion of the ridge member. Therefore, the building material can be arranged with a simple structure by the inner and outer bundles, and the building material and the upper end of the climbing beam are
Through the attachment piece, it is possible to efficiently connect without using a bundle material, and to efficiently bridge the climbing beam material. Further, since the attachment piece is attached to the building material in advance, the climbing beam material can be conveniently fixed, and the workability can be improved.

The climbing beam can be extended to the eaves corner of the house beyond the outside bundle to form a roof set of a side roof, while the climbing beam is placed outside the bundle. A half gable roof set can be formed by terminating at. As described above, the hipped roof or the half gabled roof can be formed by using a building material having an inclined portion, and the number of members can be reduced and the cost can be reduced.
