Abstract

Thermally insulating sound-proof plates for floor pavements, roof insulation and street foundations has a non-flexible, hard outer shell of concrete with a loose filling of expanded clay or shale. Specifically the outer shell may also be gypsum, hard PVC or cement-bound wood wool.

Description

Process for the production of heat and sound insulation panels for partition walls, storey ceilings and roof insulation with a hard, rigid outer shell and loose insulation material made of expanded clay or expanded slate.

The invention relates to a method which makes it possible Heat sound insulation and insulation panels with loose insulation material made of expanded clay or expanded slate 0 It is known that expanded clay or expanded slate can be found in liquid concretes, Asphalt bitumen or mixed in foams, which is more or less the Pick up moisture and diffuse.

In contrast, according to the invention, the room and footfall sound is resolved and strongly dampened by the loose bulk of the inside the plate Expanded clay balls in different grain sizes According to the invention there are also none Vapor diffusion, since the so-called. Breathing of the plate through its thin outer shell, the made of plaster of paris or concrete or cement-bound wool or plastic (perforated) consists.

Therefore, according to the invention, this insulation board is particularly suitable as a partition External wall insulation, ceiling and floor insulation, roof membrane insulation and as Roof insulation through the loose embedding of expanded clay, suitable It is known the various insulation panels, rock wool mats, foam panels or expanded Cork grist plates cannot cancel or prevent the hygroscopic effect0 In contrast, according to the invention by the loose, loose structure of the poured Expanded clay or expanded slate any accumulation of moisture prevented and avoided. All previously known insulating panels and mats have expensive defects caused by constant moisture penetration and vapor diffusion and brought about by decomposition and destruction by microbes0 In contrast is according to the invention only set material such as expanded clay or expanded slate used, which without delay the moisture on and through the thin outer shells the plate gives off and evaporates quickly.

Abb0i now shows a section through the heat X and sound insulation board O a) shows the horizontal joint to prevent sound bridges. It is also used for grouting according to the material of the car shells.

For concrete slabs with cement mortar, for gypsum with liquid plaster, at cement-bonded wood wool panels also with cement mortar0 becomes the outer shell The plate is made of plastic on a PVC basis, the mortar takes place with a plastic glue.

b) shows the outer shells of the concrete heat and sound insulation panel made of plaster of paris or cement-bonded wood wool panels or perforated plastic panels.

The thickness or strength of these outer shells depends on the Thickness or strength of the required wall thickness.

When used as an insulating panel, according to the required thermal insulation values According to the invention, the heat and sound insulation panels will have the following dimensions have: For interior walls 5 to 14 cm for insulation for roofs 4 to 6 cm as floor insulation (Heat and impact sound insulation) 3 to 6 cm as facade insulation 4 -6 cmO c) shows the horizontal joint, the wedge of which always goes into the recess below, also wedge-shaped, fits, according to the information a) is mortared.

For structural reasons, round iron or Flat steel inlaid. Since this reinforcement is not the subject of the invention, too is generally known, it will not be discussed in more detail here.

d) now shows according to the invention the loose bed, without any binding agent, of expanded clay or expanded slate in different grain sizes: 1 - 3 mm 3 - 7 mm 7 - 15mm This loose fill results in good thermal insulation, as the moisture, created by vapor diffusion, easily absorbed and evaporated.

Likewise, this loose, bedding gives a good sound insulation ( Impact sound and room sound insulation) because all frequencies are attached to the loose grain of the Break Hlhtons.

Fig.2 shows the view and a vertical section of the heat and Sound insulation board according to the invention.

a) the formation of the horizontal joint in the upper part b) the outer shell made of concrete or plaster of paris, made of plastic or cement-bonded rolling wool, c) the training the horizontal joint in the lower part of the plate.

d) shows indicates the interior of the plate, the loose filling of the expanded clay or expanded slateO Patent claims sheet So
