Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention has a structure in which a house appendage lower than the main body is connected to the side surface of the main body in a simple and efficient manner without deteriorating the strength of the roof assembly. The present invention relates to the roof structure of an appendage of a house.

[Conventional technology]

For example, as shown in FIG. 1, on the side surface S of the main body H1 of the house,
A house with a change in appearance is proposed by connecting a house appendage H2 lower than the main body H1 in series to expand the living space and providing a step C between the main roof R1 and the auxiliary roof R2. ing. On the other hand, in such a stepped roof, it is necessary to increase the roof assembly rigidity in order to withstand the wind pressure acting on the step C.

[Problems to be Solved by the Invention]

However, in such a roof, since the bundle material that supports the main roof R1 and forms the step C is directly erected on the rafter forming the attached roof R2, the structure is complicated and the roof rigidity is poor and the strength is reduced. .

Further, in houses, unitization and standardization are being promoted from the viewpoints of productivity improvement, cost reduction, etc., but such a conventional roof hinders standardization of the house main body H1.

The present invention is based on the fact that an additional bundle material is separately arranged on the outside of the side surface of the main body bundle material of the house main body portion and the horizontal purlin material is bridged between the auxiliary bundle materials, and the stepped attached roof is attached to the main body portion of the house main body portion. It is an object of the present invention to provide a frame structure for a house appendage that can be easily and strongly formed without affecting the frame structure.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a frame structure of a house appendage of the present invention is a frame structure of a house appendage that is provided in contact with a side surface of a house body and forms a house appendage lower than the house body. There, the auxiliary bundle lower than the main body bundle is arranged outside the side surface of the main body bundle that receives the beam of the house main body and is juxtaposed along the side surface. At the upper end, a base piece that is vertical and flat and is parallel to the side surface is bolted to the base piece of the joining metal fitting provided with a connecting piece that projects outward, and to the connecting piece, of the house attachment part. While supporting the upper end of the climbing beam, the end of the horizontal purlin material is bolted to the base piece of the joining metal fitting to bridge the lateral purlin material between the upper ends of the accessory bundle materials, and the horizontal purlin material Supports the upper end of the rafters for roof formation in the appendage of the house. .

[Action]

Since an additional bundle material is separately provided outside the side surface of the main body bundle material that receives the climbing of the main body of the house, and the main body roof and the auxiliary roof are independently formed and supported, the structure is extremely simple and the house It does not affect the frame structure of the main body, and enables standardization of the main body of the house, unitization of the main body of the house, and addition of additional parts to the house when, for example, remodeling.

The external force acting on the main roof and the step is individually supported by the main body bundle, and the external force acting on the accessory roof is individually supported by the accessory bundle, so that the roof strength can be increased and the additional part of the house is formed. It is possible to suppress the change in the strength balance of the main body of the house due to, and to prevent the occurrence of weak points.
