Reinforced roof structure of a prefab modular shed

Abstract

The present subject matter discloses a novel roof designs of a blow-molded storage shed that enhances structural stability while ensuring ease of assembly and disassembly. The roof assembly features a beam support frame with multiple interconnected beam columns and crossbars, providing robust support for the roof structure. A central roof panel, equipped with an embedded seamless folding groove, folds to create a roof peak during installation. Additionally, side roof panels are connected to the central roof panel, forming a cohesive and durable roof assembly. This design optimizes both strength and ease of construction.

         7 . The roof assembly of  claim 6 , wherein the top edge of the door lintel further comprises limiting protrusions, and the plurality of downward slots further provide limiting grooves into which the limiting protrusions are engaged with. 
     
     
         8 . The roof assembly of  claim 1 , wherein the embedded folding groove has thinner plastic material than rest of the central roof panel. 
     
     
         9 . The roof assembly of  claim 1 , wherein top surfaces of the central roof panel and the one or more side roof panels form a stepped structure that gradually descends from the center to the sides. 
     
     
         10 . The roof assembly of  claim 1 , wherein at least one of the central beam column and the central crossbar is collapsible before installation. 
     
     
         11 . The roof assembly of  claim 1 , wherein top surfaces of the central roof panel and the one or more side roof panels form a stepped structure that gradually descends from the center to the sides. 
     
     
         12 . The roof assembly of  claim 11 , wherein the one or more side roof panels are connected with one or more wall panels via positioning slots and connectors. 
     
     
         13 . A roof assembly of a blow-molded modular shed, comprising:
 a beam support frame configured to support the roof assembly;   a plurality of roof panels coupled with the beam support frame, wherein the plurality of roof panels comprise a central roof panel that is foldable via an embedded folding groove to form a roof peak, and one or more side roof panels connected to the central roof panel; and   at least one door lintel installed under the plurality of roof panels.   
     
     
         14 . The roof assembly of  claim 13 , wherein the embedded folding groove has thinner plastic material than rest of the central roof panel. 
     
     
         15 . The roof assembly of  claim 13 , wherein the beam support frame comprises at least one central beam column and a central crossbar positioned in the middle of the at least one central beam column. 
     
     
         16 .
