Le corps isolant (1) pour le gainage réfractaire et pour l'isolation thermique de tubes (2) a un profil incurvé intérieurement et, le cas échéant, également extérieurement, qui doivent être montés sur le tube (2) et présentent chacun un bâti d'appui (3) adapté à la courbure du tube (2) à isoler, une couche de fibres (4) compactée et appliquée depuis l'extérieur sur le bâti d'appui (3), une couche d'une masse réfractaire (5) appliquée vers l'extérieur sur la couche de fibres (4) et plusieurs ancrages (6) pénétrant depuis le bâti (3) à travers la couche de fibres (4) dans la masse réfractaire (5). Le bâti d'appui (3) est constitué de plusieurs bandes ondulées (7) se croisant en grilles et les ancrages (6) s'engagent par des pattes de fixation (6a) repliées sous des demi-ondes (7a), tournées vers la masse réfractaire (5) des bandes ondulées (7). The invention relates to insulating bodies (1) for the refractory sheathing and for the heat insulation of cooled tubes (pipes) (2), skid-rail tubes (2), supporting tubes (2) or upright tubes (2) in preheating furnaces, pusher furnaces or rocker bar furnaces (walking beam furnaces), which are designed to be curved in profile on the inside and, if appropriate, also on the outside, which are to be fitted on the tube (2) and which each exhibit a supporting framework (3), adapted to the curvature of the tube (2) which is to be insulated, a compacted fibre layer (4), provided on the supporting framework (3) towards the outside, a layer of refractory compound (5), provided on the fibre layer (4) towards the outside, and a plurality of anchors (6) which project from the supporting framework (3) through the fibre layer (4) into the refractory compound (5). The insulating bodies are further developed in that the supporting framework (3) is constructed from a plurality of corrugated bands (7) which intersect in a grid-like manner, and the anchors (6) engage, by means of angled-off fastening lugs (6a), beneath half-corrugations (7a), oriented towards the refractory compound (5), of the corrugated bands (7).
