Description

For the sound insulation shock isolation system of the floor slab pipeline through walls of building construction

Technical field

The utility model is related to wall soundproofing field, more particularly to a kind of floor slab pipeline through walls for building construction every Sound shock isolation system.

Background technology

In the unusual extensive of current application, the materials for wall for largely using at present is steam pressurized mixed to wall sound insulation technology Solidifying earth building blocks, plastering using two-sided 1 more than the .5mm thickness of cement mortar after being built a wall with the building block, live sound transmission loss is about 42dB or so, almost cannot meet use requirement in all of standard, so as to need to increase appropriate on the basis of wall Sound-insulating structure.

Current wall generally carries out sound insulation by the way of lightgage steel joist adds Thistle board, and it mainly has single light steel dragon Bone Wall body can obtain the sound transmission loss for being not less than 45dB, and double lightgage steel joist walls can obtain the sound transmission loss for being not less than 50dB, but mesh The tubing such as communicating pipe of air exchange between indoor and outdoor are often installed on preceding wall, so as to cause sound-insulating structure to be destroyed, So as to cause soundproof effect significantly to weaken, and connection tube fluid can produce larger noise, so that noise passes through wall It is communicated to each position.

Noise elimination structure substantially using the internal material with porous, many gaps, improves the contact area with air, makes sky Noise vibrations in gas are converted into, and the vibrations on object are then converted to interior energy, realize the noise vibrations in consumed cabin air, reach suction Receive the effect of noise.

The Chinese patent of Application No. 201620203695.8 discloses a kind of wall through pipeline sound insulation system, and it passes through It is arranged with metal sleeve outside communicating pipe, the metal sleeve and main blanket of glass wool is surrounded between communicating pipe, the main glass Cotton felt two ends around being provided with main polyphenyl rod, the main polyphenyl rod by it is non-harden sound insulating seal agent respectively with connect pipe outer wall and Metal sleeve inwall is bonded, and secondary blanket of glass wool, the secondary mineral wool felt ring (collar are surrounded between the installation through-hole and metal sleeve Secondary polyphenyl rod is arranged with, this sound insulation noise elimination structure can reduce most noise, but for the sound insulation noise reduction of the metope that punches The critical problem of effect is the sound insulation noise reduction of two ends of installation through-hole, when the sound insulation noise-reducing structure of installation through-hole position adds By force, noise could be reduced transmitted in concrete wall by way of vibrations, but this kind of sound insulation noise-reducing structure disappears at present Sound effective value is concentrated mainly on connection pipe outer wall, causes also more noise to be transmitted by concrete wall, so that uncomfortable Room Ying Yu high to noise requirements.

Utility model content

The purpose of this utility model is to provide a kind of sound insulation shock isolation system of the floor slab pipeline through walls for building construction, its Have the advantages that to improve the concrete wall soundproof effect near metal sleeve.

Above-mentioned technical purpose of the present utility model technical scheme is that：One kind is used for building construction Floor slab pipeline through walls sound insulation shock isolation system, including concrete wall, the concrete wall two sides are provided with sound panel, institute State concrete wall and be provided with installation through-hole, pipe is communicated with the installation through-hole, metallic sheath is arranged with outside the communicating pipe Pipe, the metal sleeve and is surrounded with blanket of glass wool between communicating pipe, also ring between the metal sleeve and installation through-hole inwall Blanket of glass wool is wound with, around polyphenyl rod is provided with, the installation through-hole two ends are equipped with coniform contracting at the blanket of glass wool two ends Mouthful, the necking is provided with coniform mounting head, and the mounting head center is provided with the fixed via installed for metal sleeve, two It is bolted between the individual mounting head, V-arrangement silencing channel, the silencing channel two ends is provided with the concrete walls body Communicated with installation through-hole two ends respectively, V-type fix bar is provided with the silencing channel, the fix bar is provided with several noise eliminations Ring, the fix bar two ends contradict with two mounting heads respectively.
