DD149100A1 - METHOD FOR THE MAINTENANCE OF ROOFS, ROOF WATER EQUIPMENT AND CHIMNEYS - Google Patents

Abstract

The invention can be applied without restriction in compliance with the fire protection regulations in the construction industry. The aim of the invention is to extend the repair intervals for roof systems with simple means and to extend the period of time for the use of structural parts. This is done by local partial coatings with polyester resin, which is prepared for use under or on roofs accordingly with flame retardants, thixotropic agents and paints and reinforced by Glasseidenstapelbindermatten. The Ruestungsaufwand is avoided.

Decaying for the maintenance of roof areas, roof drainage systems and chimneys.

Field of application of the invention

The invention relates to a method for maintaining the functionality of roof surfaces, roof drainage systems vmd chimneys, regardless of their material composition such as cardboard, brick, zinc, aluminum ·, steel sheets, PVC, asbestos cement, concrete, etc., by using glass fiber reinforced unsaturated polyester resin with the addition of flame retardant and colorants. The invention relates exclusively to renovation old roof systems, preferably in residential buildings., Buildings for social facilities and industrial buildings without special fire protection requirements,

Characteristic of known technical solutions

The normative useful life of structures and parts of buildings and thus the need for restoration of their funllungsfähigkeit by replacement is variable and depends significantly on appropriate care and conservation measures.

Traditionally, a roof skin is maintained by the Texlersatz of the existing cover material, by Umdeelcur gene and application of additional Be lags s chi chten chills, connections to penetrations of all kinds, gutters and downpipes are repaired in principle by partial replacement; Chimney heads are grouted, given new covers or are demolished and completely or partially renewed. This work is for pitched roofs and roof drainage systems

associated with the use of scaffolding and require a high manual labor.

In the patents DDR YP 55 127 "Process for the coating of roof surfaces, such as cardboard and concrete roofs or the like," and BRD OS I95835O "covering for the covering or cladding of buildings" are equally described procedures by a full-surface coverage slightly inclined Roof surfaces to create a new maintenance-free roof skin by layer-wise application of glass fleece mats with polyester »

This type of construction does not take into account the thermal expansion behavior of larger polyester surfaces and is only approved by the State Building Inspectorate for fire protection reasons when using flame retardant additives or flame retardant additives for max. Therefore, this method is currently meaningless for practical use.

In the patent DDR WP 128 ^ 59, a method for the production of terminals and all existing inputs and structures by using GUP laminates is described, which is supported by a release film and the assurance of two slip planes, the expansion behavior of the building parts.

With this method, the new production (substitution) of hitherto predominantly metallic or PVC-produced roof plumbing elements is now proposed by locally finished polyester segments. Repairs to roofs using this method thus correspond to the replacement of the damaged components with traditional use of the required scaffolding. Repair measures of roof drainage systems or chimneys are not covered in the claim.

The patent DDR WP 88 190 is expected to replace the well-known zinc cover by another sealant in new buildings and proposes to decay in similar Veise for repairs of old buildings. The Usage of cast resin is here in conjunction with prefabricated plastic moldings and corresponds in their nature also a new production (substitution) of the affected parts of the building, in repairs the existing Grundlcörper serves as a mold for the new polyester gasket.

The newly manufactured sealing and roof drainage elements are with high manual effort when using partially prefabricated elements and without taking into account the then continued to cut ends of the old remaining parts of the building to produce. This objective is technically and economically contestable.

Object of the invention:

The aim of the invention is to restore the functionality of already repaired roof surfaces, roof drainage systems and flue gas systems and to extend the natural repair interval with the least possible effort and labor,

Essence of invention: '

The invention has for its object to close inlet points on roofs and roof drainage systems without the use of scaffolding and still stable chimneys to protect g & Qen progressive weathering damage and thus to extend the normative service life of a roof system.

Features of the invention;

The object is achieved in that a repairing composition of unsaturated polyester resin with admixtures of EMammschutzmitteln, thixotropic agents and colors using accelerator and Harteranteilen and proven by fiberglass staple mats is applied in layers to the repair parts.

Unsaturated polyester resins are understood as meaning unsaturated condensation products of dihydric alcohols and dicarboxylic acids which are predominantly dissolved in monostyrene and react and harden by the addition of catalysts and associated accelerators

 By Buna-Schkopau is the Värmeformbeständigkeit

for laminates from UP-AS 232 * 1- with ^ 200 ° C and the firing temperature with ^ 50 ° C. The resistance of GUP to weathering without protective measures is set internationally at 10 to 30 years. Before the coating, the repair surfaces are thoroughly cleaned of dust, dirt and loose particles. At the chimneys are destroyed covers and fired joints put back. The surfaces should be covered with polyester and laminated as needed with fiberglass staple mat. The order takes place with pitched roofs and schlier accessible places from the underside, 'at accessible places using safety harness the upper side

 On the roof covering, including all penetrations and the gutters, the ¥ ass density is thus restored, and func- tional safety is restored at the funnels with regard to weather resistance, gas-tightness, stance and a constructive shell.

The burning behavior of de-repair parts can

if necessary by further protective coatings with polyester, paints, sanding u, ä. be improved.
