Description

Purlin combination reinforced structure Technical Field The utility model belongs to the field of constructional engineering, and particularly relates to a purline combined reinforcing structure. Background Purlines are also called purlines, horizontal roof beams perpendicular to roof trusses or rafters and are used for supporting the rafters or roof materials, the purlines are transverse bending (usually two-way bending) members, single-span simply-supported purlines are generally designed, and the common purlines comprise solid-web type purlines and light steel truss type purlines. At present, a plurality of projects such as newly added photovoltaic, air conditioners and the like are particularly arranged on the existing roof, a plurality of roofs are originally designed into simply supported C-shaped purlines, the bearing capacity is limited, the bearing requirement of the new projects is difficult to meet, the methods such as directly enlarging the section of the purlines and replacing the purlines or encrypting the purlines are extremely high in reinforcing cost due to the fact that the roofs are disassembled and the like, and a plurality of newly added projects of the roofs cannot be implemented, so that the existing purlines are reinforced, the bearing capacity is improved, and the method has higher practical value. Disclosure of utility model In order to solve the problems in the prior art, the utility model aims to provide a purline combined reinforcing structure so as to realize the reinforcement of purlines, improve the bearing capacity and facilitate construction.
