DE202005017083U1 - Prefabricated system for heated building basement, has solid concrete face slab with thermal insulation and anchor steel sheets - Google Patents

Abstract

The system consists of a solid concrete face slab (1) with thermal insulation (2) and anchor steel sheets (3). The slab has a length of 30 to 50 centimeters to adjoin basement corners at 45- or 90-degree angles. The thickness of the slab is 5 to 8 centimeters allowing the slab to be recessed for doors, windows, etc., while the insulation has a thickness of 5 centimeters.

Description

ordinary construction in the base area of heated buildings

The Requirements for thermal protection of heated buildings require insulation of the base area of buildings, preferably without thermal bridge. In practice, therefore, a perimeter insulation outside on the basement walls, or on the strip foundations of non-basement buildings up to the top Cellar ceiling or floor plate applied. This insulation will from a depth of 30 cm below ground to the desired Height of Plinth plastered with base plaster. On the insulation are first adhesive putties and the insert of reinforcing fabric applied for crack prevention.

Problems in the Base area of heated buildings

Of the water-repellent base plaster is a relative to the (soft) insulation relative rigid coating and therefore less resistant to thermal and mechanical stress and tends - despite reinforcing fabric - too strong Susceptibility to cracking. To In addition, the plaster loses its water-repellent form due to formation of the first cracks Function and is increasingly the destruction by moisture and Exposed to frost. In further progress, moisture can also in the rising walls penetration.

In practice arise mechanical stresses z. Eg by plaster and earthworks in the course of the freestanding design immediately a building. In particular, the pressure of soil compaction equipment (vibrating plate) acts directly on the base area and causes first hairline cracks in the plaster. After a few Years are already the first frost damage caused by extended cracks and flaking noticeable.

Of the after usual execution Made pedestal area of heated buildings is a very sensitive and susceptible to damage Building detail, in the outdoor area subject to the strictest conditions.

In The practice is also common the base plaster does not reach the required depth (30 cm) below the Terrain surface introduced, often the already existing filling of the excavation is in the way and a new (mostly manual) digging is spared.

The o. a. Problems are caused by the finished base parts as a component system for heated Buildings - with the in the protection claims formulated features - completely solved. The Solid finished base parts from the component system are outstandingly resistant against mechanical and thermal stress. Pads each Kind of around the building can without hesitation to be grown directly to the base. The Finished parts are largely insensitive to scratches and damage. (Z. B. by children's toys o. ä.) The finished base parts from the component system offer in the sensitive Base area of heated buildings a towering one Protection against surface water and rising damp.

The Component system from the finished base parts simultaneously solves the geometric Problem of different wall thicknesses in the basement and the upper floors, the in the staircases often by masonry on the inside of the concrete cellar exterior wall have to be compensated.

The Component system made of finished base parts can be used independent of the further construction (solid or wood construction).

The Finished base parts have a finished surface on which no longer be plastered final got to.

By The component system made of finished base parts thermal bridges are completely avoided.

to Clarification of the finished base parts is attached to the drawing directed.

All finished base parts consist of a solid, usually reinforced concrete header shell ( 1 ), a thermal insulation ( 2 ) and one or more anchor parts ( 3 ), preferably made of sheet steel. For a pleasing design of the building corners without collision of the finished base parts directly at the corner of the building special corner pieces are available.

The Component dimensions are necessarily the building dimensions and the terrain conditions customized. The finished base parts receive all necessary recesses for doors, windows and other wall breakthroughs in the ground and basement. To avoid cracking from internal and external constraints of the components the maximum horizontal component length is between 5.00 and 6.00 m.

The dimensions of the anchor parts ( 3 ) are necessarily the dimensions of the attachment shells ( 1 ) customized. The anchor parts ( 3 ) are used to assemble the base parts of the basement walls or the strip foundations and the permanent anchoring of the finished base parts after concreting the basement ceiling or floor slab. The anchor parts can be hori by their small zontal bending resistance in the insulation plane movements inf. record thermal change in length of the finished base parts.

The Finished base parts are butted in the simplest case, but can also obtained a vertical changeover gap for concealed sealing of the butt joints. The resulting joints are generally filled with sealant (bituminous or silicone-free pastes, elastomeric waterstops o. ä.) waterproof closed.
