Problems solved by technology

[0005] Traditional SIPs also suffer from the disadvantage of having a foam core formed from an organic foam material which has proven to be highly flammable and presents a significant fire risk
[0006] Furthermore, because of the structure of conventional SIPs, the panels will only support less than the specified maximum load in limited orientations

Embodiment Construction

[0024] The following disclosure relates to methods for manufacturing composite construction elements. A construction element is generally any object used to construct a part of a building, bridge or similar structure (including smaller structures such as landscape elements) or may constitute an entire structure. A composite construction element comprises at least two parts with different properties, typically formed of different materials. In particular, the disclosed method manufactures a composite construction element using computer-controlled equipment in response to computer instructions derived from a computer model of the composite construction element. To manufacture a composite construction element, the apparatus is directed by computer instructions to manufacture a core of a first construction material by selectively removing and / or applying the first construction material, and to cover at least a portion of the core with a hardenable second construction material to ...

Abstract

A method for fabricating a composite construction element, used to construct buildings, bridges or similar structures, using a computer-controlled apparatus. The method involves providing computer instructions derived from a 3D model of a composite construction element to the apparatus, selectively operating the apparatus to fabricate a core from a first building material, selectively applying a settable second building material to the core to form a skin thereon, and at least partially curing the skin to form a shell at least partially enclosing the core, the core and shell thereby forming the composite construction element.

Description

technical field [0001] The invention relates to the manufacture of construction elements, which are objects for the construction of buildings, bridges or similar structures. In particular, the invention relates to the manufacture of composite construction elements having at least two parts possessing different material properties. Background technique [0002] When constructing buildings, the usual method of creating interior and exterior walls, as well as floors and roofs, is to install prefabricated panels, known as structural insulation panels (SIP). A SIP is a composite construction element consisting of a core of foam material sandwiched between two substantially rigid structured flat sheets or panels. These panels are very popular as they may allow to increase the efficiency of building works, since large, structured and generally light-weight panels can be installed quickly and easily, they are very strong and have high insulation values. [0003] A SIP typically co...
