FR2839994A1 - Thermal flow breaker for wall and floor slab joint comprises thin insulating element folded along pre-marked lines to cover floor slab edge - Google Patents

Abstract

The thermal flow breaker is in the form of a thin insulating strip of a multi-reflective material that is folded along pre-marked lines (3) so that it covers the edge of the floor slab supported by a double wall with cavity insulation. The upper and lower sides of the insulating strip have cut-out tongues (1) that are bent outwards and connected to reinforcing elements in the wall masonry.

Description

connection (3).

  e The present invention relates to a thin insulating element whose function is to be a thermal flow breaker at the edge of the floor (Fig1 and Fig2), and the Draining Block / Double partition (Fig5, Fig6 and Fig7) which is combine to allow occasions

  of loads and a good connection Floor / Wall.

  The Thin Insulating Element is of the "Multi-Reflective" type. It is in the form of an insulating strip, the width of which allows it to wrap the edge of the concrete floor against the formwork plank. Its width also allows it to wrap the underside and the top of the edge of the concrete floor (Fig1 and Fig2) and its small thickness allows it to

  perform this function without affecting the solidity of the floor.

  In the enveloping parts located below and above the floor, are

  cutouts on trots with a 10 cm square dimension (1).

  The tabs thus formed, put before the courage of the floor in a folded down position in the stiffeners of the block, will contribute to the efficiency of thermal flow breaker

  this invention ((2) folding the tongue).

  The Floor / Wall junction provides for a load recovery and the connection of the materials forming the floor with the materials forming the wall. These two obligations prevented the adoption of a system covering the floor edge. By the association of the Thin Insulating Element and the Draining Block / Double dry-laid partition (F: 3), with a cell length of 30 cm, the stiffeners integrated in the brickwork, have their continuity assured by the cutouts (1) placed above the stiffeners (the cutouts and

  stiffeners have the same center distance of 30cm).

  The tongues will be folded down, before casting, in all the stiffeners used.

  The Draining Block / Doubie partition 30cm long at a height of 25cm, it consists of cell trots. The central cell 14cm wide and the two external cells (the draining and the double partition) are 8cm wide each. An 8 cm vertical offset allows the use of its assembly technique, and a 1 cm horizontal offset allows, not only to ensure alignment and easy installation but

  also to ensure the airtightness of the work that the block is used to achieve.

  To ensure easy positioning of the Thin Insulating Element, two premarkings (3), corresponding to the thickness of the floor, will be made during the manufacture of this element. The part of the Thin Insulating Element intended to return to the top of the floor will be temporarily folded down over the Element Planelle of the Block Draining / Double Partition range, during the courage of the floor concrete, guaranteeing against the

  risk of accidental clogging of the drain by concrete.

  The suitable elements making up the range of the "Draining / Double partition" block are shown in the figures from 8 to 13:

  -The Angle Element Fig 8, Fig 9, Fig 10.

-The Element Planelle Fig 11.

-The Element Lintel Fig 12.

-The Chaining Element Fig 13.

  Two slightly modified elements will allow the use of the Thin Thermal Flow Breaker Insulation Element, with the traditional block of cm wide, recreating the conditions of connection by the primers of stiffeners and of load resumption by the loadings of support distribution

  direct with the primers of stiffeners.

  -The Assembly Fig 14 -The Planelle Element 20 (4) Fig 15 -The Chanage Element 20 (5) Fig 16 The Thin Insulation Element associated with the Drainage Block / Double partition Allows: -to treat [ia insulation Floor / Wall link - to remove the thermal poets generated by this link

  thanks to its quality as a thermal flow breaker.

  This association also allows: -to respect the load recovery necessary for the courage of the piancher -to respect the support of the floor on the entire bearing surface of the block The cutouts provided in the 'Thin Insulating Element correspond to the stiffeners of the Draining Blocks / Double partition. The 30cm spacing used in the arrangement of the stiffeners also allows the support of the joists of the slab floor, one stiffener in two, the spacing of the

  floor joists being standardized to 60cm.
