Oven module with intermediate expansion joints

An oven module of the type for use in industrial baking applications and having a longitudinal axis along which objects to be baked are passed, said oven module comprising:

• a rigid floor section having an interior floor structure and an exterior floor structure which are attached at opposite longitudinal ends of said floor, the exterior floor structure including a plurality of first lateral support members spaced along the length of the floor section and connected to a plurality of first longitudinal support members and an exterior floor surface positioned upon the first lateral support members, the interior floor structure including an interior floor surface, a plurality of second longitudinal support members spaced along the width of the floor section and connected to a plurality of second lateral support members at opposite ends of the floor section and first means for accommodating thermal expansion in the interior floor surface, the first means for accommodating thermal expansion located intermediate opposite longitudinal ends of the floor section;
• a rigid roof section, having an interior roof structure and an exterior roof structure which are attached at opposite longitudinal ends of the roof section, the exterior roof structure including an exterior roof surface, a plurality of third lateral support members spaced along the length of the roof section and connected to the exterior roof surface, and a plurality of fourth lateral support members located at opposite ends of the roof section and connected to the exterior roof surface, the interior roof structure including an interior roof surface, a plurality of fifth lateral support members spaced along the length of the roof section and connected to the interior roof surface, the fifth lateral support members being interspersed between the third lateral support members, and second means for accommodating thermal expansion in the interior roof surface the second means for accommodating thermal expansion being located intermediate opposite longitudinal ends of the roof section;
• and
• at least two ridged wall sections each having an interior wall structure and an exterior wall structure which are attached at opposite longitudinal ends of the wall section, each interior wall structure including an interior wall surface, a plurality of first vertical support members spaced along the length of the wall section and connected to the interior wall surface and a plurality of second vertical support members connected to both the interior wall surface end to a third longitudinal support member, each interior wall structure including third means for accommodating thermal expansion in the interior wall surface, the third means for accommodating thermal expansion being located intermediate opposite longitudinal ends of each wall section, and each exterior wall structure including an exterior wall surface, a plurality of third vertical support members being interspersed between the first vertical support members, the exterior wall surface also being connected to the second vertical support members.
