DE2950055A1 - Thermal or sound insulation for buildings - consists of straw mats which are spiked and plastered to wall - Google Patents

Abstract

Pre-formed straw mats provide thermal or sound insulation to buildings or walls (7). Spikes (4) are driven into the wall and two layers of straw mating (8, 11) with joints offset are hung onto the spikes. A metal grid (13) is tied to the outside ends of the spikes and the whole is then plastered (14) to a true surface parallel to the original wall. The assembly is protected from the weather by a capping (17).

Description

Method and device for insulating a building

The present invention relates to the insulation of buildings, in particular the sound insulation and thermal insulation.

In the past, straw was used in the construction of walls, that with others Materials was mixed, but the procedures used for such constructions are tedious and costly and are no longer used. Such walls however, they offer effective protection against cold and heat, and concrete walls can do this no longer offer in modern buildings.

Furthermore, it is not possible to put straw on a wall that has already been created to raise.

The invention avoids these and other disadvantages and has to Task set, a method for the insulation of buildings and an insulating material, which allows its use to indicate using straw, rushes, corn stalks, Reeds or similar materials. This object is achieved in that first an insulating layer in the form of straw or straw mats (or similar) is produced, which is then applied to the entire surface to be protected is, on which then a relatively thick layer of mortar or other binder of this kind is applied so that it forms an exactly parallel wall to the above-mentioned surface.

According to a development of the invention are used to attach the Straw mats on a wall (or other surface) in this surface pins such a length that it passes through the layer or layers of straw stand out.

It has proven to be useful if each straw mat or each Straw mesh made of straw, rushes or similar material and made in a suitable manner Way is brought in a known manner in a layer of uniform thickness, and according to a further feature of the invention, this straw mat with a cover very large mesh size such as netting, wickerwork, wire mesh or elastic wire mesh is provided which, depending on the dimensions of the straw mat, the wrapping of an im essentially cuboid mattress or a foldable or rollable strip forms. This cover prevents any scattering of the straw, allows one easier handling of the mattresses or strips without the free circulation of air or driving in nails, pins, screws and the like (which easily can penetrate the large meshes). Furthermore, the envelope complete or partial impregnation with any agent.

Advantageously, two superimposed on the masonry Layers of straw or mats anchored in such a way that the joints of the first layer covered by the second layer, then on the free end of the pins a network is applied parallel to and at a certain distance from the straw mats, and eventually so much mortar (or other binder) is applied that the network forms an inner reinforcement. When the pins and the network are out Made of metal, the network is preferably welded onto the free end of the pins.

When the mortar is applied, it penetrates through the meshes of the reticulated Wrapping and penetrates more or less deeply into the straw layer. This will the outer surface of the net-like covering is integrated into the mortar. After drying the mortar, the net-like covering and the straw mat form a unit, their Components can no longer be removed are. On the one hand, that's the mortar The reinforcing network adheres firmly to the wall and there, on the other hand, the straw mats holding pins are also firmly attached to the same wall, it is easy understandable that after drying the above-mentioned unit of straw mat, Cladding and mortar with said wall is firmly connected and thus with this forms a uniform masonry.

The method is advantageously carried out on the outside of building walls applied. Here the wall itself and the entirety of the masonry is isolated protected against the rigors of the weather.

In order to better explain the invention, an embodiment is shown below described in connection with the figures.

It shows: FIG. 1: a perspective view of a straw mat, Fig. 2: a perspective view of a wall on which a layer is applied is, Fig. 3: a perspective view of a wall with wire mesh before application of the mortar, FIG. 4: a section through a wall protected according to the invention.

To make a straw or a straw weave, hackles are used Straw 1 (or other stalks of grain or rushes) used in a regular Layer of even thickness is spread out with the help of a twine 2 is kept in shape in a known way.

The layer produced in a known manner is cut into pieces more suitable Dimensions cut and surrounded with a net 3 at its free ends sewn together and pinned onto the straw mat.

If the mat of straw is in the shape of a strip, it is it is also possible to cover it with a net and roll it up.

In order to use the insulating material produced in this way as such, long pins or needles 4, 5, 6 are hammered into the wall 7. A first layer 8 is unrolled, with this in its upper part on the wall by means of the protruding Pins attached. A second layer 9 is applied next to this first layer, next to it more until the entire surface of the wall is covered. Then one will second row of layers 10, 11, 12 applied in such a way that the joints of the first row are covered. This is made of metal on the free ends 4 ', 5', 6 'of the pins 4, 5, 6 existing wire mesh 13 is welded on and then the mortar 14 is applied.

Figure 4 shows in section the wall 7, which is covered by two layers of straw mats 8, 9, 1G, through which the pins 4 pass, and which are protected by the Mortar layer 14 is covered. It can be clearly seen that the network or metallic Wire mesh 13 is embedded in the mortar 14 and serves as reinforcement.

In order to ensure good strength, it is beneficial before Applying the insulating material to create a strip ledge 15, which acts as a support for the mortar 14 is used.

This strip ledge is advantageously in the wall 7 by means of corbels 16 (Appendices to those previously made in the wall Notches be poured) anchored. After the insulation has been completed, the upper end of the wall must be respectively.

the head of the wall must be well protected. If there is no roof, it is it is possible to build the wall through a zinc plate 17, through a cornice or otherwise to cover.
