Abstract

Metal chimney stack with perforated walls 1, 2 and other leakproofing rigidly-connectable covering stabilisers. Consisting of standardised components which can be assembled by self-positioning fitting members 3, 4, 5, 6, 7.

Description

 The object of the invention relates to a metal chimney stack with perforated stabilizing walls of solidifiable sealable coatings.

 It is intended to allow the metal structure as well as the walls to be covered with a coating eliminating any risk of corrosion or accidental leaks and self-resisting.

 It is known to use as chimney stacks prefabricated shells with predetermined dimensions and appropriate shapes or to make with heavy materials, entirely metallic materials required assembly details to have the desired seals. In addition, the metal subjected to the aggressions of external agents disintegrating quickly, from where complication of manufacture with important manpower.

 The device according to the invention eliminates these drawbacks, lowers the cost price by saving raw material, facilitates mounting with a stabilized but light and removable structure positioning the walls of the shell suitable for receiving both on site and by prefabrication a coating. mortar or other cement, anti-corrosive, waterproofing as well as decorative, allowing its adaptation to the environment.

 It is made up of a combination of a dismountable conical trunk structure formed by uprights and crosspieces assembled by nuts and bolts and by walls made of expanded metal or perforated sheet metal, the profiles of which retain the covering plaster forming a waterproofing reinforced concrete and anti-corrosion protector as well as self-resistant.

In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows in elevation the structure of the strain.

 Figure 2 shows a perspective view of the perforated sheet fixed to the removable metal frame.

 Figure 3 is a perspective view of the strain placed on a roof with its waterproofing and anticorrosive coating.

 The structure of the strain, FIG. 1, is made up of metal profiles 1, 2 and others forming uprights and crosspieces 3 supporting the upper sealing plate 4 with plug 5.

 These uprights and crosspieces are provided with holes 6, 7 receiving screws or rivets intended to fix in a removable manner the walls 8, 9 and others (Fig 1, 2) made of expanded metal or perforated plate.

 The sealing plate 4 has bent angles 10, 11, 12, 13 and others folded outwards with slight peripheral overflow 14, in order to allow the plaster or cement or mortar distributor to support its drainage rule. of the wall. This overflow can also be used to determine and regularize the thickness of the coating.

 The metal structure rests on a sealing sheet plate 15.

 The perforated sheet or expanded metal 8, 9 and the like have profiles forming dimplings for anchoring the plaster, the consistency and density of which are sufficient not to pass through the open dimplings but to adhere to them enough to produce a plate in reinforced cement, self-resistant.

 The excess quantities which would normally overflow on the internal face constitute as many masses of anchors retaining the external coating, while achieving a partial internal covering of the metal protecting it against corrosions originating from the fumes.

 The cap 16 is fixed by screws or bolts is of appropriate shape and style. It can be metallic, ceramic, cement or any other suitable material.

 The conical trunk shape of the metal frame allows stacking for storage or transport in a small footprint.

 The assembly by screws or bolts allows the disassembly and the replacement of each constituent element.

 The fixing of the shell 17 to the roof 18 is effected by any means appropriate to the type of support.

 However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as moreover the materials used for their manufacture without thereby changing the general design of the invention which has just been described;

Claims (2)

 10 Chimney stump device intended to allow the covering of the removable metallic structure and of conical trunk shape by a self-resisting coating eliminating any risk of corrosion or accidental leaks with elements lowering the cost price facilitating the assembly while allowing a prefabrication with functional form giving the possibility of ensuring storage and transport without a reduced space requirement in stacking, characterized by a demountable conical trunk structure formed by uprights (1, 2) and crosspieces (3) upper comprising a plate ( 4) with plug (5) the uprights and crosspieces being provided with orifices (6, 7) receiving fixing screws or bolts with walls (6, 9) of perforated sheet metal or expanded metal forming open dimples retaining and anchoring the protective coating in cement, mortar or other.  20 Device according to claim 1 characterized in that the removable frame (1, 2, 3) and others rests on a plate (15) and receives a cap (16) at its upper part; the fixing of the assembly (17) on the roof (18) is effected by any appropriate means (19).
