DE19738731A1 - Building system to partition-off rooms with improved sound insulation - Google Patents

Abstract

The panels (1) have hard outer shells (2,3) adhered continuously to, and sandwiching a soft damping layer (4). Edges of the panels have a tongued-and-grooved profile (1a). Internally, the damping layer or outer shells have profiling offsetting resilient stiffness of the damping layer. Preferred features:- The profiles (2a,3a) are swath, trapezoidal, comb or wave formations. One shell is shortened at the top, to assist joint formation (5) with the ceiling. All edges of the outer shells have a permanently elastic coating (7). The outer shells are hard, e.g. metal, wood, plastics, plasterboard, or sandwich structures of such materials. The sections are joined using cross- or T-brackets (8) at the same height as the panels. On the connecting edges these have tongue-and-groove profiles congruent with those of the panels. The panels may be constructed as ground- or intermediate flooring, on which only one outer shell and damping layer is provided.

Description

The invention relates to a component system for separating rooms with the aim of one to achieve high sound insulation between these rooms. The system consists of plate-shaped elements to form the room walls.

State of the art, disadvantages of the prior art

Light walls with high sound insulation have so far been called stand walls built, in which the load-bearing stud frame is created first and then is planked. The cavities are generally filled with sound absorbing material. This construction is labor intensive and due to the manual execution on site from Expertise dependent on the executor and therefore prone to errors (sound bridges) and because of the necessary manufacturing accuracy again labor intensive.

So far there have only been partition walls and simple partition walls that are soundproof and are also sound-absorbing, but often have sound bridges, and are therefore to be assessed unfavorably in terms of sound technology.

The object of the invention is to provide a component system for separating rooms create with the aim of creating a high level of sound insulation between these rooms to reach.

According to the invention, this is achieved by the measures according to claim 1. Advantageous refinements are the subject of the dependent claims.  

The system consists of plate-shaped elements to form the room walls, including sound-proofed element edges and on the other hand from special edge elements to preserve the acoustic properties when using the elements as flanking components. The plate-shaped elements are based on the double wall principle without discrete connecting points between the two Outer shells built up. The elements are self-supporting, so that they manage without additional stud frames.

Basics of the solution

The separating component system consists of plate-shaped elements from which the Room partitions (walls) are built, and made of special Edge elements that reflect the sound properties of the panel elements help with joints to other separating components (ceiling walls).

The plate elements are constructed according to the double wall principle, consisting of the outer soundproof, heavy layers and a soft intermediate layer acoustic separation and for mechanically stable connection of the layers a "monolithic" unit. The three layers of the elements are together glued and overall self-supporting.

The required deep resonance frequency of the unit is in addition to the selection suitable materials for the outer shell and the middle insulation layer in particular by profiling the inside of the outer layers (or reversed of the two sides of the insulation layer), with which the resulting Stiffness of the insulation layer is reduced in a favorable manner.

The full-surface connection of the elements makes it possible to dispense with discrete ones Connections between the shells, the sound insulation is unfavorable influence, especially if they are executed incorrectly (too stiff). By you can use the - seen across the surface - homogeneous structure of the elements to Adaptation to the structural conditions can be tailored without to lose their sound absorbing properties.  

The edges of the plate elements are designed so that the Plates can be plugged together in a soundproof manner without sound bridges surrender. This is achieved by making the element edges tongue-and-groove like this are formed so that only the corresponding layers touch each other.

Crossing points or T-joints of plate elements can be perform sound bridge-free so that from the outer layers of the continuous Elements matching strips are cut out into which the adjoining Elements are used. A simultaneous connection of the two soundproofed outer shells of the elements with flanking walls or ceilings (floors), which would represent a sound bridge, is either by the shortened formation of one of the two outer shells and permanently elastic Backfilling of the joint avoided or by using a special one Edge connector. Such special edge fittings are also there can be used where several plate elements meet. Such pre-made Butt joints have the advantage of greater security in the quality of the Execution.

Advantageously, prefabricated, in particular, room-high Plate elements on the top and bottom edges already shortening one of the contain two outer shells, the load of the shortened shell by one suitable strip of resilient material, attached to the lower edge of the shortened shell, can be distributed.

Technical application area

The invention can be used as a quick-to-assemble, lightweight partition system in Buildings are used, especially where there is sound insulation between the rooms are required, which do not have the same weight, single-shell components to achieve.

Due to unnecessary stud frames and a prefabrication of the edge and The joints of the elements are quick, simple and functionally reliable possible.  

If only two layers of the 3 layers of the wall elements are used - insulation layer and an outer layer - so these remaining elements can be used as facing shells, floating screeds and suspended ceilings with a sound-absorbing effect become.

The system proposed here does not require a stand and provides the sound-absorbing function through the prefabricated shape or prefabricated Connection elements safe. While with stud walls the adaptation to the structural conditions affect a large number of parts (stands, planking, damping filling), the elements proposed here only have to be in one Work process can be tailored to suit.

Known sandwich systems of comparable design have either rotating ones Connections along the edges of the elements (sound bridges) or get theirs Load capacity through the use of stiff cores. In both cases, the sound insulation Multi-layer structure capability not used.

Embodiments

The following four pictures show an example of an element structure and Edge connections.

Picture 1 shows two abutting walls,

Picture 2 a cross connection,

Picture 3 a wall between building floor and ceiling,
and Figure 4 shows a prefabricated element for connecting four walls.

Figure 1 shows two wall elements 1 with two outer shells 2 , 3 and insulation layer 4 in between. The two outer shells are profiled on the inside 2 a, 3 a like a sawtooth. Of course, other profiles are also conceivable, e.g. B. trapezoidal, rounded, meandering or corrugated sheet-like profiles. This profile can also be arranged on the insulation layer 4 , depending on which layer is easier to profile. In most cases it will not be the harder outer shell 2 , 3 , but the soft insulation layer 4 . The profiling also serves to adjust the spring stiffness of the insulation layer. The coarser the profile, the "softer" the insulation layer between the two outer shells.

At the joints, the outer shells are glued to the insulation layer, e.g. B. with Plastic adhesives or power connectors such as Pattex.

The outer shells can be made of hard plastic, e.g. B. cement-bound Polystyrene, wood, plasterboard or even made of metal plates, and optionally be built in a sandwich structure, e.g. B. a metal-wood, or Wood plaster, or metal-plastic sandwich structure. The thickness depends on the material be between 1-10 mm.

The insulation layer can be made of mineral or rock wool, impact sound insulation boards, or Soft foam panels exist. The thickness becomes about 10-40 mm depending on the material be.

The outer edge 1 a advantageously has a tongue and groove shape for connecting several plates.

Figure 2 shows a cross connection, the two horizontal plates have the tongue and groove shape, the other two plates have shortened outer shells 3 b on one side. Only the outer shells 2 , 3 or only the insulation layers 4 are connected . Structure-borne noise cannot therefore be transmitted from one outer shell 2 to the opposite outer shell 3 . Figure 2 shows the insulation layer running from top to bottom. Since this may be technically complex, the intermediate piece 4 c can of course also be glued in place.

Figure 3 shows floor-to-ceiling panels after installation, although the insulation layer is not shown for clarity. The outer shell 3 is shortened at the upper and lower edges 3 b and thus enables the attachment of a permanently elastic joint 5 on the building ceiling 6 a and 6 floor, which also causes no structure-borne noise above the building floor or ceiling from the an outer shell 2 can reach the opposite outer shell 3 .

For room-high walls, it can also be advantageous to provide the edges of the components facing the floor or ceiling with permanently elastic coverings 7 or, as mentioned above, all edges of the components 1 and 8 .

Figure 4 shows a prefabricated element 8 for the connection of four mutually perpendicular components 1 with tongue and groove profiles 8 a congruent to the edges 1 a.
