HEAT INSULATING FLAT STRUCTURE

The invention relates to a heat-insulating planar structure comprising spaced-apart frame beams and elements therebetween, made mainly of rigid insulating material, the edges of which are formed with overlapping parts. The invention relates generally to wall, floor and ceiling structures.

Much of the detached houses and similar buildings currently under construction are constructed of long timber, often with soft thermal insulation between them. A small element is also widely used, in which the thermal insulation is placed in an almost closed "box". When building from long timber on the construction site, there must be a lot of professionalism, and in addition 15 disadvantages of the method are the heavy workmanship of the construction and the poor dimensional accuracy of the structural parts. The disadvantage of the small timber-framed elements in use today is that in order to stay inside the insulation, the element has to be made almost closed, which consumes a lot of raw material and is complicated and quite heavy to handle and sensitive to various damages. The installation of the elements is inaccurate due to their weight and they are not suitable for use on the lower and upper soles.

25 Cano Structures Inc. of Canada manufactures and markets a product similar to the level structure mentioned in the introduction. In it, a piece of cellular polystyrene is arranged between the wooden beams provided with fibreboard hot plates, the edges of which are shaped to fit inside the web of the beam. The beam and the cellular polystyrene body 30 form a completely uniform layer. The cellular polystyrene body between the beams prevents the beams from buckling and thus increases the load-bearing capacity of the structure.

The object of the present invention is to provide an inexpensive and as simple as possible planar structure for all structures between hot and cold. The characteristic features of the invention are set out in the appended claims. By means of the invention, by connecting insulating pieces of basically the same size to each other and to the body pieces, a larger structural part of the desired size is obtained in each case. The desired insulation property and structural strength can be selected by choosing the material of the insulation and the frame and their dimensioning. Thus, the use of similar elements in different parts of the building reduces the number of different ways of working, facilitating the construction process and 5 resulting in cost savings.

The invention will now be described with reference to the accompanying drawings, which show an embodiment of the invention.

10 Figure 1 shows a perspective view of a structure related to a frame beam.

Figure 2 shows a cross-section of the planar structure at the body piece.

Figure 1 shows by way of example a part of a wall structure, which shows the basic structure of a planar structure according to the invention. The frame beams 1 are placed at regular intervals and one or more rows of elements 2 are placed between them. The frame beams consist of two support beams 4 and 5, which are fastened to each other by means of interconnected 20 6. Between the beams 4 and 5 there is a certain gap. The overlap joints 3 are formed with grooves at the points of the tie supports 6, whereby the elements 2 can be attached to the frame beam 1 from the side and the projecting overlap joints 3 between the support beams 4 and 5.

By reinforcing the tie support 6 and placing it obliquely between the support beams 4 and 5, the load-bearing capacity of the frame beam is considerably increased when these two support beams together form a load-bearing beam.

30

The element 2 consists of a plurality of superimposed layers which, by means of a stepped arrangement, form said overlapping parts 3 at the edges.

Figure 2 shows the more detailed structure and placement of the elements 2 in connection with the frame beam 1. In the figure, the structure is cut at the binding support 6, whereby the protruding ends of the inner plates 9 and 10 of the elements 2 show grooves arranged for the binding support. The elements 2 can, of course, be manufactured in many ways, but even with the same material, it is advisable to assemble the element 2 from separate plates 7-10, which are glued together. Such production of large pieces by gluing is particularly well suited for cellular polystyrene bodies, because according to the prior art the production of thin bodies 5 is fast and it is best to assemble large pieces from smaller parts. At the same time, this technique allows any plate to be replaced with another material. One or more inner sheets can be replaced, for example, by hard wool or polyurethane sheets. In addition to 10 cellular polystyrene sheets, a wool sheet can be selected as the surface sheet. The cellular polystyrene pin sheet can be coated with a metal sheet, which also provides a new type of surface structure.

In the installation situation of Fig. 2, the element 2 is mounted on the frame beam 1 on one side and the second element is being pushed onto the frame beam and the first element on the opposite side.

The surface plates 7 and 8 are smaller than the inner plates and are placed 20 symmetrically in the middle of the element. The inner plates 9 and 10, on the other hand, are arranged in stages so that said overlapping parts are formed at the edges of the element. The plates 9 and 10 are of equal size, but when placed eccentrically in different directions, the necessary grooves and projections are formed from the surface plates to the edges.

25. When a wire-like nail-like element is used as the bonding support, the fastening of the support beams 4 and 5 can be carried out finally after the installation of the elements 2, whereby the overlapping parts of the elements remain pressed between the support beams 4 and 5.

30

In the structure according to Figures 1 and 2, the main load-bearing capacity is provided by the support beam 5, according to which the structure is dimensioned.

By strengthening the tying supports 6, the support beam 4 is functionally included in the frame beam 1, whereby its load-bearing capacity 35 increases considerably. In this case, correspondingly stronger grooves must be made in the overlapping parts 3 of the elements 2 for the reinforced bonding supports, but this is not a disadvantage.

With flexible materials, the surface plates 7 and 8 can be left under low tension between the frame beams, thus providing absolute tightness.

5 The surface structures are easily attached to the support beams 4 and 5.

In the example according to Figures 1 and 2, the ventilation space is left on both sides of the structure and an installation space for electrical and other piping is additionally formed on the inside.

Advantages of the planar structure according to the invention compared to other methods in use: 1. Suitable for all structures between hot and cold.

2. Enables optimal dimensional accuracy.

3. The strength properties of the rigid insulating material are effectively utilized.

4. Joining the elements is easy without nails, 20 screws or glues.

5. The joints of the joints become tight without additional seals.

6. Simple structure.
