Abstract
A shuttering system for a wall in a building comprises shuttering elements (1) of an insulating material that is equipped with cavities (4) for concrete and reinforcement. The shuttering elements (1) are intended to be assembled to a complete wall. The cavities (4) comprise a plurality of columns (4) of a waterproof material, such as plastic or waterproof cardboard. The columns (4) are arranged substantially vertical when the shuttering elements (1) are assembled. The insulating material comprises inner and outer wallboards (2, resp. 3) of mineral wool or another fire resistant material, and the columns (4) are situated between the wallboards (2, 3), and fixed thereto.
Description
CONSTRUCTION ELEMENT.
The present invention relates to a shuttering according to the introductory part of claim 1.
Background A wall in a building comprises load bearing elements and insulating elements. When concrete is used as the load bearing material, it is common to place insulation on the inside and/or the outside of a cast wall. Using this method, comparatively large quantities of concrete will be used. An alternative to this is to cast concrete columns, and place insulation in between and/or on the inside and the outside. This is a relatively time-consuming process; as the shuttering must first be erected and the concrete columns cast thereafter. The shuttering must then be removed, and insulation placed. Usually, the shuttering must be disposed of after use.
Previously is was known to utilize shuttering elements made of expanded polystyrene, having vertical and horizontal channels for receiving concrete. The disadvantage here is that expanded polystyrene is very combustible, and must be covered with plaster, or similar material.
From NO patent publication 41.594 there is known a method for casting building constructions, in which a shutter of paper or cardboard is used, which after casting will form a permanent part of the construction. With this method, nothing else is attained other than avoiding the step of removing the shuttering. Paper or cardboard promotes little, or no insulation of the construction.
Object
It is thus an object for present invention to provide a shuttering system that is easy to erect, that provides a ready insulated construction, and that is as little combustible as possible.
The invention
The object of the invention is achieved by a device having features as stated in the characterizing part of claim 1. Further features are clear from the dependent claims.
SUBSTITUTE SHEET I
Example of an embodiment
The invention will now be described in greater detail, by an example of an embodiment and with reference to the enclosed drawing, showing an exploded view of elements incorporated in a system according to present invention.
The basic component of the system according to the invention is a shuttering element 1. The shuttering element 1 comprises an inner and an outer wallboard 2, 3 of mineral wool, and a plurality of intermediate columns 4 of waterproof cardbord. For transport, the element 1 can be collapsed, as the wallboards 2, 3 can be pressed against each other, and the cardboard columns folded.
In the example shown each element has four cardboard columns 4, of which two cardboard columns are used as shutering channels. In the free cardboard columns 4, wooden battens may be situated, keeping the construction more stable before and after casting. Preferably, the distance between the shuttering channels, and thus the finished concrete columns, will be 60 cm. The wallboards are preferably 120 cm. The wallboards 2, 3 extend somewhat beyond the outer upper and lower extremities of the cardboard columns. Alternatively, the cardboard columns may extend the total height of the wallboard 2, 3, so that on assembly of the shuttering elements 1, they abut the cardboard columns 4, of upper and lower shuttering elements. In this case, a transition sleeve should be placed between two adjacent cardboard columns, in order to ensure that the supplied concrete does not flow outside the channel that is formed.
The wall with shuttering and insulation is assembled through an element 1 is prepared by a horizontal joining element 7 being put in the lower edge of the element 1. This causes the wallboards 2, 3 of the element 1 to spaced apart by the correct distance, and the cardboard columns 4 to unfold. Then the element 1 is situated in the corner of a foundation wall or a plinth 5 and is fixed thereto by means of building foam. Next shuttering element 1 is situated on the plinth 5 and is fixed to the first shuttering element 1 by means of a vertical connector element 6 made of mineral wool situated against the outermost cardboard columns 4 of the respective adjacent
shuttering element 1. All of the lowermost row of shuttering elements are fixed to the plinth 5 by means of building foam.
In the vertical direction, two horizontal connector elements 7 are placed between two adjacent shuttering elements 1. These are placed so that free vertical channels are formed along two of the cardboard columns in two stacked shuttering elements 1.
The vertical and horizontal connector elements 6, 7 are put half-way into two adjoining elements 1. Thus, the connector elements 6, 7 will, together with the wallboards 2, 3, act as a tongue and groove between two adjoining elements 1.
The individual shuttering elements 1 may be held together by means of plastic cramps and/or building foam (not shown). Strip iron or bolts are placed for the attachment of nailing studs.
When all of the wall is erected, concrete is poured into the vertical channels which are formed by the cardboard columns 4. In a per se known manner, the shuttering may be put vibrated in order to fill the channels completely. When the concrete has set the wall is complete with load bearing columns and insulation, and inner and outer covering may be attached to the nailing studs.
The shuttering forming columns 4 can also be produced in another material other than waterproof cardboard, such as a suitable plastic material. Also, the wallboards 3 can be produced in a material other than mineral wool, in this respect, e.g. fire resistant fibres may be suitable, as this material has both fire inhibiting and insulating qualities.
It may also be advantageously to provide the wallboards 3 with a wind and moisture barrier, so that the wall may be covered directly after erection.
