Summary of DESCRIPTION Lost concrete\vaben floor slab insulation formwork,

State of
Technology:

Problem:

Solution:

Achieved
Advantages:

The lost concrete honeycomb floor insulation formwork belongs to the technical field of residential construction” Floor ceilings of the usual construction type are usually cold, heavy, monolithic concrete ceilings or assembly ceilings made of individual parts such as stone suspended ceilings ” The construction of monolithic concrete ceilings requires a high expenditure of concrete, reinforcing iron and formwork material. Such ceilings are also only suitable for thermal insulation measures and cladding with visible panels with the help of considerable retrofitting&ogr;

The invention specified in the protection claims is based on the problem of creating an insulating formwork that is or becomes a structural component of a concrete honeycomb floor slab and with the help of which such concrete honeycomb floors are constructed in an insulated, lightweight and monolithic manner.

This problem is solved with the features listed in the claims.

The invention ensures that the insulating formwork can be additionally sound and heat insulated on the underside without great effort, offers plenty of installation space and the underside mounting battens for visible panel ceilings

DESCRIPTION (Summary) Lost concrete honeycomb floor slab insulation formwork _&bgr;

Achieved

Advantages: can be used for reinforcement _o The material cost

The saving advantage compared to comparable solid concrete ceilings is around 44 % _a The weight advantage with approximately the same load capacity is around ₅₆ times that of solid concrete ceilings of the same construction height &ogr; A further advantage is that only 1/3 of the formwork, namely the 125 mm wide formwork beams of indefinite length, are removed, while 2/3 of the formwork remains part of the concrete ceiling in the form of the permanent insulating formwork»
