Abstract

A straight joint and method for connecting two adjacent construction elements, such as sandwich panels, so as to reduce or minimize thermal bridging across the elements. The sandwich panels each have a core, an outer layer, a cavity defined by a portion of the core, and a pathway through the outer layer to the cavity. The panels are erected such that the panel cores are in contact with one another. Bonding material is injected into the cavity through the pathway to seal the joint and maintain the panels in fixed relation to one another.

Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates generally to constructing buildings, and more particularly, to connecting adjacent sandwich panels with a straight joint without creating a thermal bridge across the joint.DESCRIPTION OF THE RELATED ART

[0002] There is an increasing demand for lower-cost buildings such as houses, warehouses and office space. The demand for lower cost buildings is particularly strong in developing countries where economic resources may be limited and natural resources and raw materials may be scarce. For example, in areas of the Middle East or Africa, conventional building materials such as cement, brick, wood or steel may not be readily available or, if available, may be very expensive. In other areas of the world, poverty may make it too costly for people to build houses or other buildings with conventional materials.

[0003] The demand for lower-cost housing also is high in areas afflicted by war or natural disasters, such as hurricane...
