Ladite masse comprenant le renfort est connectee mecaniquement au noyau par des organes de fixation discrets s'etendant vers ou dans ledit noyau de telle sorte que les organes de fixation de differents cotes du noyau ne se touchent pas. Un procede de production dudit element de construction est aussi decrit.Construction element comprising a core (1) made of a material having a low specific weight and optionally serving as thermal insulation, a reinforcement (3) on at least two dimensions of the core (1), and a curable mass (2) , optionally applied after installation on the spot on the sides of the core provided with a reinforcement. Said mass comprising the reinforcement is mechanically connected to the core by discrete fasteners extending towards or in said core so that the fasteners on different sides of the core do not touch. A method of producing said building element is also described.

Description

A BUILDING CONSTRUCTION ELEMENT AND A METHOD FOR THE PRODUCTION THEREOF.
The present invention relates to a construction element as stated in the introductory part of the following claims. The invention also refers to a method of producing said construction element.
There are known construction elements the opposite reinforcement nettings of which are mechanically and galvanxcally connected by a continudus metal wire extending vertically in a zigzag pattern between the opposite reinforcement, nettings. Thus, vertical trusses are formed between the opposite reinforcement nettings. An expanded polystyrene insulation is provided between said trusses. After installation a hardenable mass, e.g. concrete or plaster, is provided on both sides of the element.
Construction elements of this kind are manufactured under the trade name Impac Panel by Covington Brothers Building Systems, U S A. These construction panels, however, have the disadvantage that said continuous wire between the reinforcing nettings forms a thermal bridge, which is unsatisfactory from an insulation point of view, especially in cold regions. Also, the manufacture of said known panel is complicated.
An object of the present invention, thus, is to avoid the disadvantages of the known construction element. According to the invention the reinforcement, e.g. reinforcing irons, is mechanically connected with the core by attachment members, e.g. straps, extending obliquely or diverging into said core or an adhesive. According to another feature of the invention there must be no contact between the attachment members from various sides of the core.
According to the present invention said construction element is manufactured as follows:
At least on two sides of said core a reinforcement, e.g. a reinforcing iron netting is provided, adjacent or at a distance from the core; the reinforcement is attached to said core by attachment members, provided on or in said core in such a manner that the attachment members from the different core sides do not touch; and the core with its reinforcement, is, if desired, after installation on site provided with a hardenable mass, e.g. concrete so that said mass envelopes the reinforcement.
Further features of the invention will appear from the claims.
The present invention will now be described with reference to the attached drawing.
Fig. 1 is a sectional view through a practical embodiment of a construction element according to the invention.
Fig. 2 illustrates how attachment members may be provided according to the invention.
Fig. 3 illustrates a modification of the construction element according to fig. 1.
The core 1, e.g. a cellular plastic material, is provided continuously if desired, over the entire length of the construction element. The reinforcements 3, e.g. reinforcing iron nettings, are provided on each side of said core adjacent or at a distance from the core surfaces. The reinforcement 3 is secured by attachment members 4, e.g. straps, that are forced into said core in such a manner that the free strap ends diverge, and that the straps do not touch. Then, a hardenable mass 2 is applied to the sides of the construction element, if desired after it has been installed on site. Said hardenable mass may e.g. be concrete.
The attachment members 4, e.g. straps, may optionally be provided as indicated in fig 2, i.e. in a regular manner. When strap 4 is forced in it will be deformed in points 6.
The core, e.g. of a cellular plastic material, may consist of polystyrene or another suitable low density material that can serve as an insulation.
Fig. 3 shows a modification of the construction element, where the reinforcement 3' is provided in the mass 2' that is applied and where the attachment members 4' with one end project into the core 1 and with the other end project into the reinforced mass 2'.

Claims

C L A I M S :
1. A construction element, comprising a core of a material having low specific weight and optionally serving as a thermal insulation, a reinforcement provided at least on two sides of said core and a hardenable mass, optionally applied after installation on the reinforced sides of the core, characterized in that the reinforcement (3) is in mechanical contact with said core (1) by individually securable attachment members (4) which extend to the core surface or into said core.
2. A construction element as claimed in claim 1, characterized in that said attachment members (4) provided in the different reinforced sides of the core do not touch.
3. A construction element as claimed in claim 1 or 2, characterized in that said attachment members (4) consist of straps or an adhesive.
4. A construction element as claimed in claim 1, characterized in that said core (1) consists of a cellular plastic material known per se.
5. A construction element, comprising a core of a material having low specific weight and optionally serving as a thermal insulation, and a hardenable mass applied on at least two sides, optionally after installation, characterized in that said hardenable mass (2') is provided with the reinforcement (3') and is substantially connected with said core (1) by attachment members (4') projecting from said core.
6. A construction element as claimed, in claim 5, characterized in that said attachment members (4') do not meet from their core sides.
7. A method for the production of construction elements as claimed in claim 1 or 2, characterized in that a reinforcement (3), e.g. reinforcing iron nettings, is provided at least on two sides of the core (1), e.g. consisting of a cellular plas tic material, said reinforcement being provided adjacent or at a distance from the cord surfaces, that the reinforcement is attached to said core by individually securable attachment members (4), e.g. straps, in such a manner that said members do not touch, and that said core with its reinforcement is provided with a hardenable mass (2), e.g. concrete in such a manner that said mass completely envelops said reinforcement (3), optionally after installation.
