The invention relates to a joint between corner edges (1a, 3d; 2a, 4d; 1b, 2b; 3b, 4b; 3c, 4c; 1d; 2d) of site huts (1, 2, 3, 4) arranged adjacent to each other with a space (A, B, C) between them, or between a supporting surface (6) and a corner edge of a site hut when arranged in an elevated manner with a space (D) below the site hut. The space is covered by a connector element (7, 8, 9, 10, 11, 12, 13, 14, 15) comprising a sheet member (71, 81, 91, 101, 111, 121, 131, 141, 151) and an insulating member (72, 82, 92, 102, 112, 122, 132, 142, 152), said sheet member forming an exterior surface and the insulating member covering the space (A, B, C, D) substantially entirely. In an assembly comprising such a joint a chamber (16), preferably closed, is formed between the site huts.

The invention provides a method for making a pipe section comprising; providing a mat (1) formed of a fibre matrix impregnated with an aerogel, xerogel or cryogel, the mat having a first major face (2), a second major face (3) opposing the first major face (2), a first edge (4) defining a longitudinal direction, a second edge (5) substantially parallel to the first edge (6), a third edge defining a transverse direction that is substantially perpendicular to the longitudinal direction and a fourth edge (7) substantially parallel to the third edge; applying an adhesive (8) to the first major face; winding the mat around a mandrel (13) to provide a wound mat having an inner surface (11) defining an inner circumference and an outer surface (12) defining an outer circumference and a longitudinal axis which is substantially perpendicular to the planes of the inner and outer circumferences and substantially parallel to the transverse direction of the mat; and slicing the wound mat substantially radially between the outer surface and the inner surface to provide a cut extending in a direction substantially parallel to the longitudinal axis.
摘要:
The invention relates to a method for manufacturing an insulating composite containing mineral fibers, aerogel and binder. This method implies the step of suspending the fiber webs and aerosol in an air flow thereby disentangling the fiber webs and mixing fibers, aerosol and eventually binder homogeneously. The apparatus described combines spinning of the fibers, collecting them as webs, disentangling the fiber webs in suspended air, mixing the fibers with aerogel and cement as well as pressing and curing the mixture to a consolidated product of density 150 to 800 kg/m3.

摘要:
A mineral fiber plate product is produced by producing a first non-woven mineral fiber web containing mineral fibers predominantly arranged in a first longitudinal direction and segments of the first mineral fiber web are arranged in a partly mutually overlapping relationship for producing a second non-woven mineral fiber web, which contains mineral fibers generally transversaly relative to one another. The second mineral fiber web is folded transversely for producing a third non-woven mineral fiber web. The third non-woven mineral fiber web is cured for producing a cured non-woven mineral fiber web from which a mineral fiber plate, or alternatively, a tubular insulating element is cut. In packaging, the volume of the mineral fiber plate may be reduced to 40 % - 60 %.
