[Detailed description of the invention]

0001

[Industrial Application Field] The present invention enables a hipped or semi-gabled roof to be created with a simple structure by constructing a ridge member with a sloped part fixed to one end of the ridge passing through the main ridge on inner and outer bundles. Regarding the structure of the ridge that can be formed.

2. Description of the Related Art The panel construction method is often used in houses in which the roof, walls, etc. of a house are formed by arranging panel bodies such as roof panels and wall panels on a frame body using a steel frame body.

[0003] Also, such houses have a hipped roof that has a main ridge that forms the ridgeline of the roof, and a pair of ridges that extend in a V-shape from the end of the main ridge to the corner of the eaves of the house. While this is sometimes adopted, a semi-gable roof is also often used where the ridge ends at the side eave of a gable roof that extends obliquely upward from the corner of the eaves toward the gable.

[0004] The roof assembly of such a hip roof or a semi-gable roof includes, for example, a ridge material along the main ridge, a climbing beam material along the descending ridge, and a small climbing beam that is perpendicular to the eaves and connected to the climbing beam material. Furthermore, it is formed using frame materials such as purlins that connect horizontally between the climbing beams.

[0005]

[Problems to be Solved by the Invention] In such roof assemblies, conventionally, the end of the ridge material and the upper end of the climbing beam are connected by a bundle of materials being raised at the intersection of the end of the ridge material and the upper end of the climbing beam. , it was installed by supporting the upper ends of the climbing beams, respectively.
In addition to increasing the number of man-hours involved in installing such bundles, there are cases in which the bundles cannot be installed upright depending on the arrangement of the beams below, so an improvement has been desired.

[0006] Furthermore, there is a large difference in structure between a roof assembly forming a hipped roof and a roof assembly forming a semi-gable roof, and it is difficult to develop a new structure in which both can be formed from the same basic roof assembly. His appearance was strongly requested.

[0007] The present invention is characterized in that a ridge material is fixed to one end of a downwardly sloping part that slopes with the flow gradient of the triangular roof section between the ridges at one end of the ridge passing through the main ridge, and is constructed on inner and outer bundle materials. Basically, by pre-installing a mounting piece for bolting the climbing beam at one end of the slope, it is possible to conveniently connect the ridge material and the climbing beam without using bundles, and it is also possible to connect the ridge material and the climbing beam without using bundles. The purpose is to provide a ridge structure that allows construction of a semi-gable roof with a simple configuration.

[0008]

[Means for Solving the Problem] The present invention has a descending ridge at one end of the main building that opens in a V-shape with respect to the main ridge and extends downward, and a space between the main roof portion on both sides of the main ridge and the descending ridge. A structure of a ridge forming a hipped or semi-gabled roof having a triangular roof part, the ridge part being made of shaped steel and passing through the main ridge, at one end thereof, has a downwardly sloping part inclined at the flow gradient of the triangular roof part. The ridge material with one end fixed is bolted to the other end of the sloping part, and the outer bundle material is arranged at both ends of the splicing material in a direction perpendicular to the flow slope of the triangular roof part, and the other end of the ridge part. At the same time, at one end and both sides of the inclined part,
A mounting piece is preliminarily provided along the descending ridge for bolting a climbing beam extending to the outer bundle material.

[0009]

[Function] The ridge material fixes one end of the downward sloping part that slopes with the flow slope of the triangular roof part to one end of the ridge part that passes through the main ridge, and fixes the end of the downward slope part that slopes with the flow slope of the triangular roof part to the other end of the slope part. The joints are bolted together at right angles. Further, outer bundle members are arranged at both ends of the joint material, and the ridge member is constructed by the outer bundle members and the inner bundle member arranged at the other end of the ridge portion. Further, the upper end of the climbing beam extending along the outer bundle member along the lower ridge member is fixed by bolting to a mounting piece welded in advance to one end and both side surfaces of the sloped portion of the ridge member. Therefore, the ridge material can be arranged in a simple configuration using the inner and outer bundle materials, and the upper end of the ridge material and the climbing beam material can be
Through the attachment piece, the connection can be made efficiently without using bundled materials, and the installation of the climbing beam materials can be made more efficient. Furthermore, since the mounting pieces are attached to the ridge material in advance, the climbing beam material can be conveniently fixed, improving work efficiency.

[0010]Also, by extending the climbing beam material beyond the outside bundle material to the corner of the eaves of a house, a roof assembly of a hipped roof can be formed; By terminating at , a half-gable roof truss can be formed. In this way, a hipped roof or a semi-gabled roof can be formed using a ridge member having a sloped portion, and it is possible to reduce the number of types of parts and reduce costs.
