Description

The The present invention relates to a device, in particular for Vibration and / or sound decoupling according to the preamble of the claim 1.

State of technology

to Decoupling between structures in terms of transmission of sound, vibrations or vibrations are different Devices known. In particular, when installing z. Stairs, Ramps, railings or handrails come Schallentkopplungsanordnungen used.

For example are elastic sleeves for sound insulation in prefabricated stairs known in which a sleeve is inserted into a recess of a wall is prefixed and over there a filling material firmly fixed. Either then becomes a part of a staircase inserted in the sleeve or in the sleeve was already before insertion inserted into the wall recess a stair pad part.

Become frequent for the Sleeves for vibration or acoustic decoupling elastic materials used. For optimal sound or vibration decoupling it is necessary that the elastic damping material abuts the male and a defined transition to adjacent components or wall sections forms the desired vibration or sound decoupling to enable. A disadvantage of previous devices for decoupling vibrations or sound is that in particular when installing it to the impairment the elastic damping material can come.

Task and Advantages of the invention

task It is the object of the present invention to provide a device in particular to provide vibration and / or sound decoupling between structures, which is comparatively robust and also in critical Installation requirements a comparatively high vibration or sound decoupling effect allows. This object is solved by the claims 1 to 3.

In the dependent claims Advantageous embodiments of the subject invention are shown.

The Invention goes first from a device in particular for vibration and / or Sound decoupling between structures, with a basic body, the at a first building is fixable and a receptacle for a plug of a second building structure, which is supported in the inserted state on the first structure, wherein the main body a Includes decoupling material. The decoupling device relates in particular a staircase sound decoupling element. A first aspect The invention resides in that the basic body in the region of the decoupling material opposing and essentially flat outsides has, of which at least one covered with a surface-rigid cover is. This can provide a particularly robust decoupling device become. In particular, this provides a decoupling device, the simple means the comparatively soft decoupling material effectively protects against permanent deformation or mechanical damage. Because the decoupling material can already at relatively low external mechanical Actions such as those encountered during incorporation e.g. Occur regularly in a wall niche can, a significant one Show reduction of the decoupling effect. Will the decoupling material especially during installation mechanically loaded over a certain limit, the e.g. is above an elastic deformation limit is the decoupling effect of Entkoppelungsmaterials permanently restricted or can in the individual case also essentially fail. The decoupling material can by the inventive arrangement safely protected become resistant to permanent compression, indentations or other deformations, in which e.g. the outer or inner structure of the decoupling material is changed because the cover acting forces flat distributed. In addition, it can be achieved that the Entkoppelungsmaterial over the entire surface of the Covering element abuts adjacent areas of the first structure or point loads are excluded, what an optimal Decoupling effect is advantageous.

The invention makes use of the knowledge that it is readily possible with the cover, pre-fix the decoupling device eg in a recess of the first structure in a wall recess for later fixation with mortar, foam or other filling materials. This often happens, for example, via a wedging with wedging elements, which are clamped between an outer side of the decoupling device and walls, for example, the wall recess. In the process, compression or deformation of the decoupling material may hitherto occur, since a certain pressing force is necessary in order to ensure a firm bracing situation for reliable prefixing of the decoupling device. By covering with the cover can be achieved that the support forces, for example, between punctiform enclosed shim and decoupling material spread over the entire area, which was calculated according to the bearing size and the expected traffic load. So lead ben the sound-absorbing properties of the decoupling material received unrestricted. A labor-intensive and time-consuming manual underlay of underlay elements or sheets for load distribution during assembly or their slippage can be avoided. The decoupling device according to the invention is characterized, inter alia, by a particularly good handling.

Also can mortar residues and the like. Or surveys on the walls of the wall recess to an undesirable push in or lead to a violation of the decoupling material. With a face stiff Covering a robust protective skin on the decoupling material is realized on the one hand, on the other hand, a comparatively low elastic compliance of the decoupling material can absorb. For example, because one not completely to be excluded low elastic stress of the decoupling material during installation can be absorbed by the cover spring, which by the surface rigidity is reached. It is particularly suitable for clamping the decoupling device, if at least one lower side or an opposite upper side of the decoupling device covered with a cover is where the decoupling device particularly advantageous with walls of the first structure is clamped. For a secure prefixing, it is usually sufficient, the decoupling device in the vertical direction or up and / or down to brace.

When Decoupling material comes in particular a material with energy-absorbing, absorbing or insulating Properties in question. In particular, a material with sound-absorbing, elastic or shock-consuming Properties, for example an elastic PUR material. The elastic Material can be open or closed-cell foam or rubber material be. In particular, an elastic PUR material is suitable, which sold under the name SYLOMER. The cover element preferably has a thickness in the millimeter range. The main body is in particular formed in one piece.

One Another essential aspect of the invention is characterized from that on the main body floating in the region of the decoupling material a surface-rigid cover is arranged. Thus, the above advantages can be realized. In this case, the cover at different positions outside of the Decoupling device may be arranged. The cover can e.g. be loosely held or fixed selectively fixed or have a low mobility relative to the base body. The cover element can be used on different external forms of the basic body be tuned so that the cover flat on the body in Areas of the decoupling material is applied. This can be a optimal decoupling effect on all covered by a cover Positions of the body be set up. The cover element can by its floating Arrangement on the decoupling material slight relative movements to body or to the adjacent sections. This is special during prefixing in difficult installation situations or at only insufficient precisely prepared attachment points or wall recesses for the introduction the decoupling advantageous.

One third essential aspect of the invention is that the body in the area of the decoupling material opposite and substantially flat outer sides that has over a paragraph graduated are formed. This can be achieved that the corresponding locations of decoupling material ideal for decoupling Have quantity or layer thickness. For example, areas can be of the basic body about which to a lesser extent one Vibration or sound transmission is expected to apply accordingly less decoupling material. Other Areas of the body over which as expected vibrations or more strongly transmitted sound will, can In contrast, be provided with more decoupling material. The different ones Areas can along a dividing line, in particular via a step-like shoulder of the Entkoppelungsmaterials be separated.

A advantageous embodiment of the subject invention provides that the cover element with opening is provided. This can be a particularly intimate and stable connection the cover with the decoupling material can be realized. For example, the curable Decoupling material in liquid Condition are connected to the cover or molded on this or thermally connected to it. In this case, the decoupling material partly in the openings flow into, what a particularly reliable Connection between the cover and the decoupling material allows in particular form-fit or material-locking.

It is particularly advantageous if the cover element is designed as a perforated material, mesh and / or braid. For example, a particularly preferred sheet metal material with a hole pattern or a perforated plate can be used in a particularly simple and cost-effective manner, wherein the number or size and shape of the openings or the holes can be variably selected. A network or a mesh, for example made of high-resistance material or steel or plastic can form a particularly strong connection with the decoupling material and at the same time ensure the surface stiffness of the cover.

In a preferred embodiment of the subject invention, the base body not with the cover provided outside profiled sections on. This can increase the stability of the connection the decoupling device can be achieved with the first structure. In the Usually, the decoupling device in an opening of the building in such a way introduced that an intermediate area between the outside the decoupling device and the structure remains free. To firm Fixation of the decoupling device is this clearance with mortar, construction foam or similar filling materials filled, so that after their curing the decoupling device fixed in the building, for example, a wall is fixed. For one fabric or form-fitting Housing the decoupling device in a building, for example Elevations and / or depressions on or not with the Covering element covered Outer side (n) of the basic body be provided. Particularly advantageous are the profiled sections at opposite Outside of the the body configured, for example as a rib or groove structure.

Prefers is the basic body Completely from decoupling material. This can be nearly effective in an effective way the entire volume of the sound decoupling device for sound or vibration isolation can be used.

In a further preferred embodiment of the subject invention is the main body essentially designed as a cuboid hollow body, with an open front and especially closed back. Thus, the basic body, especially when complete consists of decoupling material, can be easily manufactured and to effectively perform its decoupling function. In particular, can be level or flat contact surfaces of the basic body set up, which are provided with a cover. So can in particular by means of plate-like cover a simple and optimal decoupling effect can be achieved.

Further It is suggested that at least two opposite outsides of the basic body from the surface stiff Covering element covered become. With that you can in particular a top and bottom for bracing the decoupling device be used, which is advantageous, as well as the position the decoupling device is adjustable in the vertical direction. This can e.g. by above and below introduced Verspannelemente or wedges are realized.

A preferred embodiment is characterized by having a top and a bottom of the basic body Covered by the surface-rigid cover elements are and two more opposite outsides are provided with the profiled sections. This can be a high decoupling effect with the decoupling device and at the same time a particularly advantageous fixation of the decoupling element in the first building realize, especially when the decoupling a cuboid external form shows.

advantageously, are the outside of the basic body graded so that a wall thickness of the body in Area of a receiving opening across from other wall thicknesses of the body is reduced. In order to can have a sound decoupling effect on front areas of the main body, which less critical for a vibration or sound transmission are configured accordingly with less decoupling material become. Advantageously, can comparatively reduced amounts of the decoupling material around the receiving opening the decoupling device are provided around. This section hardly bears or not for support of the second component at the first component and is only to a lesser extent for the vibration or sound transmission relevant. For example, when attaching the decoupling device reduced in a wall or wall section of the body a paragraph-like have frame-like area after installation in the Wall or wall recess one piece more than an outer surface of the Projecting wall or wall, for example, protruding over the plaster. For one flush Conclusion of the basic body can the supernatant the frame-like area then separated easily become. This is also advantageous, since a comparatively lower material thickness of the decoupling material must be severed. In addition, can the resulting intermediate area filled in by the decoupling material becomes simpler and visually appealing with a corresponding coverage be provided, for example, by a permanently elastic joint. A typical material thickness this over a decrease in decoupling material area is few Millimeters, e.g. about 6 mm. Further inside in the wall or wall section lying areas of the decoupling material of the body, which essentially contribute to sound or vibration decoupling, can for example, a significantly larger e.g. have double layer thickness, e.g. about 12 mm. Overall, can an optimal decoupling effect using the minimum amount required be achieved on decoupling material.

description of the embodiment

1 shows a staircase sound decoupling element 1 , which serves as a wall anchor for supporting a stair member (not shown) in a wall section, for example. The staircase sound decoupling element 1 includes a main body 2 from a sound decoupling material, for example from a PUR material. The main body 2 is configured essentially as a cuboid hollow body and has an insertion opening 3 on its front side, via which a support part, not shown, for example, a static support, a staircase construction can be inserted. For receiving the support part extends in the longitudinal direction of the base body 2 a rectangular rectangular cavity. On a top 4 and on a bottom 5 of the basic body 2 is in each case an upper perforated plate 6 and lower perforated plate 7 each with a hole 8th arranged. The perforated sheets 6 . 7 For example, consist of a metal material with a perforated plate thickness of about 1 mm. The perforated sheets 6 . 7 are in the body formed as a molding 2 cast in, wherein in the manufacture of the staircase sound decoupling element 1 the still liquid polyurethane material or the like, from which the basic body 2 is formed on surfaces of the perforated plates 6 . 7 adheres and in the perforation 8th the perforated sheets 6 . 7 at least over the thickness of the perforated sheet material can run. After curing of the PUR material is a stable or mechanically strong connection between the perforated plates 6 . 7 and the body 2 realized. Advantageously, is thus a gap-free or continuous connection of the body 2 and the perforated sheets 6 . 7 simultaneously with the shape of the body 2 created. In particular, therefore, no additional measure such as adhesive bond or the like for the fixation of the perforated plates 6 . 7 at the base body 2 necessary. The perforation 8th is formed in the embodiment by regularly arranged round holes.

On to the top 4 and bottom 5 laterally adjacent outer sides 9 of the basic body 2 are approximately parallel bead-like ribs 11 provided in one piece or integral with the main body 2 are formed. Ribs 11 run approximately parallel to rear edges 12 or approximately perpendicular to upper or lower edges 13 of the basic body 2 , In the staircase sound decoupling element shown 1 are exemplary four ribs 11 on each of the outsides 9 educated. Ribs 11 extend in length over almost the entire height of the body 2 , Ribs 11 are provided at their upper and lower ends with straight faces, which is particularly advantageous in terms of manufacturing costs.

In the front area of the main body 2 is the top 4 and the bottom 5 each with a step-like heel 14 forward to the insertion opening 3 deposited in the outsides 9 merges with a radius, creating a frame section 10 is formed. This to the top 4 or the bottom 5 detached and to the outsides 9 flush frame section 10 is completely without perforated metal cover. The staircase sound decoupling element 1 is on his the plug-in opening 3 opposite back with a back wall 15 closed. For attachment or prefixing of the staircase sound decoupling element 1 in a wall recess or the like, the base body 2 introduced into the wall recess, so that only a part of the frame section 10 protrudes beyond a wall outside. In the horizontal direction of installation, the ribs 11 be positioned touching or slightly spaced to walls of the wall recess. For vertical positioning of the staircase sound decoupling element 1 In the wall recess stress wedges are usually used and between walls of the wall recess and the top 4 or the bottom 5 the staircase sound decoupling element 1 clamped. This prevents that when wedging the staircase noise decoupling element 1 the PUR material of the main body 2 is compressed selectively, since the perforated plates 6 . 7 prevent deformation of the PUR material. The holes of the perforation 8th must be chosen in size or shape so that the bracing wedges do not press against the PUR material during bracing or not through the perforation 8th can occur, but only on the perforated plates 6 . 7 issue. Thus, the PUR material remains unimpaired or it is a punctual loading of PUR material avoided and it can be guaranteed optimal sound isolation. With the perforated sheets 6 . 7 In addition, advantageously, the required depending on the material of the decoupling material planar bias can be established. In addition, through the perforated sheets 6 . 7 a surface load distribution between the PUR material of the body 2 and adjoining sections in the wall. Because after wedging or distortion of the staircase sound decoupling element 1 in the wall recess are remaining free spaces between the staircase sound decoupling element 1 and filled the walls of the wall recess, for example, with construction foam. The staircase sound decoupling element 1 is thus firmly fixed in the wall. A fixation in particular against pulling out of the staircase sound decoupling element 1 forward is by means of the ribs 11 improved.

The wall thickness of the PUR material is chosen so that in the area of the support one in the main body 2 inserted staircase component or where the main load rests in the subsequent use of a higher material thickness is formed and thus optimal sound or vibration decoupling is achieved, as on the top and bottom of the frame portion 10 , In the installed state of the staircase sound decoupling element 1 , where outside such as plaster on the frame section 10 comes close to a comparatively smaller wall thickness of the body 2 formed, which is unproblematic, since here in the installed state no or almost no static load is absorbed or no significant sound transmission takes place. The reduced in material thickness material, for example, over the wall surface protrudes forward, can be advantageously separated in a simple manner. In addition, thereby the externally visible bordering surface around the staircase sound decoupling element 1 be kept relatively narrow in the area of the plaster, which is optically preferred, this area can be closed, for example, readily with a permanently elastic joint.

In principle, in addition to the embodiment shown, different dimensions or geometries of the body 2 will be realized. In principle, rectangular, square or round geometries are suitable. In the case of round outer shapes of the main body or of a cylindrical outer shape of the basic body, it may be possible to dispense with wedging of the soundproofing decoupling element. This is possible, for example, if a corresponding hole is provided in accordance with the external dimensions of the staircase sound decoupling element in the wall. Then, if appropriate, the wall thicknesses or material thicknesses over the total insertion depth in the main body could be the same. The material thickness of the back wall could possibly be weaker or stronger.
