Title:
ROOF STRUCTURE AND ROOF CONSTRUCTION METHOD
Document Type and Number:
Japanese Patent JP2021075888
Kind Code:
A
Abstract:
To provide a roof structure capable of securing sufficient rigidity against an input load and exhibiting excellent earthquake-resistant performance, the roof structure composed of a lattice purlin and girder members, and provide a roof construction method.SOLUTION: A roof structure 1 is composed of a lattice purlin 2, a girder member 3, and a reinforcing member 4 for reinforcing the joint part between the lattice purlin 2 and the girder member 3. The reinforcing member 4 has a predetermined thickness and is composed of a plate-like main body part 44 composed of an upper side 41, a lower side 42, and both sides 43. The lower side 42 is welded to an upper flange 31 of an H-steel which is the girder member 3, and the upper side 41 is welded to the side surface of a bridge member 21. The reinforcing member 4 can suppress buckling deformation of the girder member 3 even if a vertical force within an allowable range acts on the joint part between the girder member 3 and the lattice purlin 2.SELECTED DRAWING: Figure 1
