[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a simple and efficient way to construct a house attachment part lower than the main body part on the side of the house main body part without impairing the strength of the roof assembly. , Concerning the roof structure of an attached part of a house.

[Conventional technology]

For example, as shown in FIG. 1, a house attachment part H2 lower than the house body part H1 is connected to the side surface S of the house body part H1 to expand the living space, and also connect the house roof R1 and the attached roof R.
A house has been proposed that has a step C between the two and changes the appearance.

However, in such a roof with a step, it is necessary to increase the rigidity of the roof assembly in order to withstand the wind pressure acting on the step C.

[Problem to be solved by the invention]

However, in such a roof, the main roof R1 is supported by the rafters forming the attached roof R2, and the bundled materials forming the step C are erected directly, which complicates the structure and leads to poor roof rigidity and strength. let

Further, although houses are being unitized and standardized from the viewpoint of improving productivity and reducing costs, roofs of such conventional structures hinder standardization of the main body part H1 of the house.

The present invention is based on separately arranging an attached bundle material on the outside of the side surface of the main body bundle material of the house main body, and spanning the horizontal purlin material between the attached bundle materials, and the stepped attached roof is attached to the main body of the house. The object of the present invention is to provide a frame structure for an attached part of a house that can be formed easily and with strength without affecting the frame structure.

[Means to solve the problem]

In order to achieve the above object, the frame structure of the house attachment part of the present invention has a frame structure of the house attachment part that is provided in contact with the side surface of the house main body part and forms a house attachment part that is lower than the house main body part. An accessory bundle material lower than the main body bundle material is disposed outside the side surface of the main body bundle material that receives the climbing of the main body part of the house and is arranged in parallel along the side surface, and an accessory bundle material lower than the main body bundle material is arranged. The upper ends of the rafters that form the roof of the attached part of the house are supported by the horizontal purlins that span between the upper ends.

[Function] Attached bundle members are separately provided on the outside of the side of the main body bundle material that receives the roof of the main body of the house, and the main body roof and the attached roof are formed and supported independently, so the structure is extremely simple. Moreover, it does not affect the frame structure of the main body of the house, making it possible to standardize and unitize the main body of the house, and to add additional parts to the house during, for example, renovation.

In addition, since the external forces acting on the main roof and the steps are supported by the main body bundles, and the external forces acting on the attached roof are supported by the attached bundles, the strength of the roof can be increased.
Furthermore, changes in the strength balance of the house main body due to the formation of house attachments can be suppressed, and the occurrence of weak spots can be prevented.
