Abstract

PURPOSE:To remove restrictions on the sequence of construction of a down- gradient beam, an up-gradient beam, the ascending purlin of a main roof and a main house by enabling a roof to be trussed in the absence of the purlin of the main roof beneath the inside of that portion of an auxiliary roof which projects from the main roof. CONSTITUTION:In a roof wherein an auxiliary roof 2 is projected perpendicular to a main roof 1 and from one side of the main roof 1, connecting fittings 6 are affixed to the upper portion of a bundle 5 laid on a beam 4 at that portion of a roof truss which is located at approximately the center portion of a valley 3 portion defined by the main roof 1 and the auxiliary roof 2. The upper end portion of a down-gradient beam 12 is connected to the down-gradient beam connecting portion 8 of the connecting fittings 6 and the lower end portion of an up-gradient beam 13 is connected to an up-gradient beam connecting portion 9. Further, the lower end portion of the ascending purlin 14 of the main roof 1 is connected to an ascending purlin connecting portion 10 and the horizontal main house 15 end portion of the main roof 1 is connected to a purlin connecting portion 11.

In addition, conventionally the main roof 1 of the main roof 1
The lower climbing beam, upper climbing beam, main roof 1 climbing purlin, etc. could not be constructed until after 5A was constructed, and there were restrictions on the order of construction.

The present invention was invented in view of the problems of the prior art described above, and its purpose is to extend the sub-gable gable from one side of the gable main roof at right angles to the main gable roof. In a roof with a protruding roof, a roof frame can be formed at the lower part of the interior of the protruding part of the sub-roof from the main roof without the main building of the main roof, and it is also possible to create an atrium space within the sub-roof. Lower climbing beam, upper climbing beam, main roof climbing purlin,
To provide a roof frame without restrictions on the order of construction when constructing a main building.
