Definitions
- the construction materials forming part of a building may have to satisfy various requirements. E.g. in respect of load-bearing capacity, aesthetic impression, thermal inertia (thermal capacity) and incombustibility. The latter must not be overlooked since inter alia property insurance rates depend on the fire characteristics of the building materials. The lower a material's tendency to burn, the lower are the rates.
- One method which is frequently used in order to achieve the above storage and fire retardation characteristics and in part cooling characteristics consists in making use of concrete units.
- the material is after all entirely inorganic and in addition satisfies the requirement of incombustibility.
- One of the disadvantages of this construction method consists in the fact that it is difficult to make the material sufficiently insulating. I.e. impart to the construction a low "k-value" (heat transmission coefficient).
- a material which imparts a low k-value to a construction is e.g. mineral wool.
- this material there is the disadvantage of low thermal capacity.
- Glauber's salt sodium sulphate decahydrate
- this salt cannot be used in relatively large containers since during phase conversion the material is subject to stratification as a result of which the material becomes irreversible, i.e. the heat storage capacity declines until it ceases entirely (cf. e.g. the technical report 1981 :05 of the national Swedish Institute for Materials Testing (Statens Provnings GmbH)).
- the present invention proposes an arrangement by means of which a considerable number of practical problems associated with building constructions can be solved.
- the invention is not restricted only to constructions for buildings but can also be used for document safes, money safes and also boxes for accommodating electronic equipment such as computers and telephone switchboards.
- the invention consists in a sandwich unit with, from one side, an outer layer of preferably incombustible material. This is followed by an insulating material, which may be mineral wool. The next layer consists in a surface material and one then allows an air gap to form before installing the phase converting material after a further layer of outer material. Thereafter the design is the same as hitherto but in reverse sequence. As regards the material symmetry may accordingly be said to exist. But it is of course also possible to consider other sequences of material combinations. If an arrangement according to the invention is used it can be utilised for cooling, energy storage and fire retardation. With a view to describing the invention in greater detail reference is made to three figures.
- Figure 1 relates to a test described below.
- Figure 2 is a cross-section of an arrangement or unit. This figure should be regarded as one of many feasible embodiments.
- figure 3 illustrates a test arrangement. This arrangement is related to figure 1 .
- figure 2 we have a cross-section of a unit.
- the outer layer (4) may be such as to combine good strength and incombustibility characteristics with an aesthetically appealing pattern.
- Two air gaps (5) are then formed by installing the container of phase converting material (6), preferably Glauber's salt, at the centre. With units for vertical placing this consists of a number of small spaces produced with the aid of e.g. folded material (similar to corrugated cardboard) glued to the outer layer. Another way of achieving this result consists in the use of "honeycomb structures".
- the unit shown in figure 2 offers the advantage of ensuring on the one hand good heat insulation thanks to the insulating material (11). The latter can also be so selected as to achieve good sound absorption within the high frequency band.
- this layer acts as a sound damping material at low frequencies.
- FIG 3 is a test arrangement of simple design. It consists of a walled furnace containing a number of Kanthal elements capable of raising the temperature in the furnace to 1000 degrees C in accordance with the standard curve used in fire tests. The supply of energy to these Kanthal elements is controlled by measuring devices fitted within the furnace, which are connected to a regulator ensuring that the temperature develops in accordance with the "fire curve". The regulator, the Kanthal elements and the measuring device are not shown in the figure.
- the walls (10) are masonry walls and the test material (unit) (6) is placed on the furnace by way of an upper boundary. The inside of the furnace (7) is thus heated to a temperature of 1000 degrees C.
- a measuring device (9) in the form of a thermoelement is located on the unit (8). The signal of this thermoelement and the temperature in the furnace can be recorded.
- the unit is produced with basically at least one outer layer and one type of filling material.
- the filling material may, for instance, have decorative, load-bearing and fire retardant characteristics.
- the filling material often has insulating characteristics.
- a material with this structure is for instance the TNF unit from Eockwool AB.
- a durable product may be achieved in combination with the outer layer, such a product being normally described as a composite.
- Such composites consist for instance of an outer epoxy layer reinforced with carbon fibre and a filling material such as polyurethane.
- Such units are easy to produce since they need only be glued together. With the unit described in connection with the present invention an air gap is also provided. This makes the production of the unit somewhat more complicated. One can imagine two basic methods which as such are also capable of being combined.
- spacers are distributed over the surface of the unit.
- This method is subject to the disadvantage that e.g. the spacing devices may act as cold transmitting elements. This can be avoided by making these spacing devices of less thermally conductive material.
- the spacing devices are secured between the various materials forming part of the unit, including the outer layers, by gluing, welding or some other suitable method.
- Such units can be easily produced by a manufacturing process as such readily automated.
- a manufacturing process may for instance comprise glue coating machines and curing chambers for the glue applied.
- Good glues are for instance phenolic or resorcinol glues.

Abstract
Montage pour construire des bâtiments, des coffres-forts pour des objets de valeur et de l'argent et des coffrets pour ordinateurs ou tableaux commutateurs de téléphone. Le montage est une unité formée d'une couche extérieure, d'un matériau thermiquement isolant et d'un matériau de stockage d'énergie constituant un système convertisseur de phase. La figure 2 montre comment placer les couches extérieures (4) et le matériau isolant associé (11) de manière à former deux intervalles d'air (5). Un milieu calorifère comme l'air peut être conduit à travers ces derniers afin de refroidir ou de chauffer l'air tout en utilisant les caractéristiques de stockage d'énergie du matériau convertisseur de phase (6).
