FR2651261A1 - Interchangeable internal, continuous, static or renewed ventilation system for a composite or non-composite prefabricated block, with its special gluing machine - Google Patents

Abstract

Interchangeable system permitting continuous, static or renewed ventilation for composite or non-composite prefabricated blocks, with its special gluing machine, composed of a vertical orifice of any cross-section taken in each internal constituent element of the block as well as the lateral sides communicating with the upper element via orifices taken in the top of the block and for which, in the case of gluing, use will be made of a movable apparatus which is open on two faces, equipped with one or more half-cylinders in the longitudinal direction in order to deposit the binder without obstructing the ventilation. The continuity between two stages will be ensured by a hollowed-out element having a side of smaller cross-section embedded (nested) in the lower block. The arrival of air will be effected by means of a pipe in two parts ending in an open or full (solid) interchangeable stopper, which may be bent.

Description

 Interchangeable internal, continuous, static or renewed ventilation system, for prefabricated block, composite or not. with its special paste.

 Cement or concrete blocks, although recognized as "cold", are currently not provided with any system ensuring their internal ventilation by means either static or renewed and interchangeable.

 The method according to the invention overcomes this drawback.

The two elements forming the whole of the air circulation consist in the vertical plane of an orifice of any section taken d- = the base of all the internal constituent elements
block and lateral sides to ensure horizontal circulation
and an orifice of any section taken from the top of the elements
elements, inside each part, and allowing the connection to
ticale between classy rank whatever the form that these
are glued or interlocked
In the case of glued elements, an element will be used
mobile receiver on casters, adapted to the width of the element,
open on 2 sides, consisting of one or more complete semicircles
allowing the precise installation of the binder without obstructing the orifices of
ventilation,
Continuity during recovery through a concrete leveling
monobloc, a concrete floor, or a 2nd row (ex Pignon), will be provided
rée by a pipe having a side having a narrowing and is
housed in the holes on the underside of the elements of
formwork provided for this purpose.

The arrival and the possible renewal of air will be ensured
by a bi-partite element, consisting of a hollowed out main block and
one interchangeable finishing cap, solid or drilled.

According to a preferred aesthetic embodiment, the block
main air intake can be bent to accommodate
base in a leveled block machined for this purpose.

The 2 elements forming the whole of the air circulation consist in the vertical plane of an orifice of any section taken in the base of all the internal elements constituting the block (Fig 2 n 2) and the lateral sides for ensure horizontal circulation and an orifice of any section taken in the top of the elements (Fig 1 n 1) inside each part, and allowing the vertical connection between each row whatever its form these are glued or interlocking.

 In the case of glued elements, use will be made of a mobile receiving element (Fig 4) on casters (Fig 4 n08) adapted to the width of the element, open on 2 sides, consisting of one or more - complete semicircles (Fig 4 n09) allowing precise placement of the binder without obstructing the ventilation holes.

 Continuity during the recovery through a one-piece concrete leveling, a concrete floor, or a 2nd row (ex Pignon), will be ensured by a pipe (Fig 9 n 6) having a side with a narrowing (Fig 9 n 7) and being housed in the holes in the lower face of the formwork elements provided for this purpose (Fig 5).

The possible arrival and renewal of air will be ensured by a two-part element, consisting of a hollowed out main block (Fig 7 no. 4) and an interchangeable finishing cap, full or
drilled (Fig 8 n 5).

 According to a preferred aesthetic embodiment, the main air inlet block can be bent (Fig 3 n 3) in order to be housed in the base in a leveling block machined for this purpose (Fig 3).

 The transverse connection of the boxes of the block (Fig 2) ,.

will be carried out by a straight or beveled hollow element (Fig 7 n04 bis).
