RU157553U1 - SOUND PANEL - Google Patents

Abstract

A soundproofing panel consisting of two soundproofing sheets with sound-absorbing material placed between them, characterized in that the soundproofing panel is made of two soundproofing sections that are offset from one another in two mutually perpendicular directions by the overlap step of the panel ends, while the panel sections are interconnected inseparable by bonding when applying glue to the contacting surface in the form of dots or mutually intersecting perpendicular or parallel los glue.

Description

The utility model relates to noise control in the way of its propagation by isolating it and can be used as soundproofing of frame partitions in building structures of residential and public buildings.

Known soundproofing panel containing two plates made of wood fiber material and a layer of porous polyethylene foam between them, on which is applied a layer of elastic vibration-absorbing material (RF patent for utility model No. 28501 "Soundproofing and heat-insulating sandwich panel. 2002"). When assembling panels in building envelope, the panels are connected directly end-to-end, which leads to a significant reduction in sound insulation.

A similar disadvantage has a soundproof laminated panel with a vibration-absorbing layer, utility model patent No. 131397, 2013. A laminated panel with a vibration-absorbing layer consists of two metal sheets and a vibration-absorbing layer placed between them.

The vibration-absorbing layer is made of a self-adhesive adhesive composition with a reinforcing layer. The closest in technical solution and the achieved result is a RF patent for utility model No. 141334 "Flat finishing element" dated 12/07/2011, which we took as a prototype. The flat finishing element for wall and floor cladding has heat-insulating and soundproofing properties. It consists of two facing layers with supporting elements and separation layers forming an internal space that is filled with annealed quartz sand. Separating layers and supporting structures are made of cellulose and mineral wool. Monolithic construction is ensured by binders based on water silicate base, gelatin and starch. The presence of a high mass of aggregate ensures sound absorption. The ends of the sides of the finishing element are closed by gluing a fringing tape. The support elements are a honeycomb core that has found application in many soundproofing panels. The assembly of tile trim elements in building structures is carried out end-to-end with filling the joints with sound-absorbing material. The joints of the tile elements significantly reduce sound insulation. Although the finishing element itself has good soundproofing properties.

The technical task to be solved is to increase the soundproofing of the soundproofing panel.

The technical problem to be solved in a soundproofing panel consisting of two soundproofing sheets with sound-absorbing material placed between them is achieved by the fact that the soundproofing panel is made of two soundproofing sections offset from each other in two mutually perpendicular directions to the overlap step of the panel ends, while the panel sections are connected interconnected by gluing when applying glue to a contacting surface or glue in the form of mutually intersecting perpendiculars glue or dots of parallel or parallel (not indicated on the diagram) strips.

In a specific implementation example, the soundproofing panel consists of two soundproofing sections, each of which is made of one, two or more sheets 1, with sound-absorbing material placed between them 2. The soundproofing sections 3, 4 are offset relative to each other in two mutually perpendicular directions by step H overlapping panel ends during assembly. The sections of the panels 3, 4 are interconnected in one piece by gluing when applying glue to one of the contacting surfaces of the sheets or by applying glue in the form of mutually intersecting or parallel strips or dots (Fig. 1, 2, 3). Sheets 1 can be metal or non-metal from all kinds of synthetic and composite materials. As sound-absorbing material 2, you can use foamed polyurethane of the required density, rubber, thiokol, rubber-like materials, porous pumice materials, foam concrete, foam metals, granular materials, sand and others. The connection of the two sections of the soundproofing panel is carried out by glue 5, deposited on the surface of the sheet 1 of the lower section 4 of the soundproofing panel (Fig. 1). The glue for joining the panel sections is taken with elastic properties, polyurethane, rubber-like, based on thermoplastic elastomers, rubber, silicone, acrylic resins and others that have good anti-vibration and anti-vibration properties. When spotted glue is applied in the form of drops 6, they can be considered as micro-springs providing vibration isolation (Fig. 2, position 6). While, when applying glue in the form of strips intersecting in a mutually perpendicular direction and when connecting two sections of the panel, sealed air cells are formed bordered by adhesive strips 7, where all sealed air cells are already involved in the reduction of vibration (Fig. 3). In FIG. 3 shows a part of cell 8. An assembly diagram of two sections 3, 4 offset from one another is shown in FIG. 2, where H is the displacement step of the panel sections, which is necessary for high-quality panel assembly. This is achieved by the fact that the ends of the panel sections overlap each other, forming a labyrinth joint 9 filled with sound-absorbing material 10 (Fig. 4). The path of the sound wave becomes longer and more complex. All this allows you to increase sound insulation in the soundproof panel. A batch of panels is manufactured and tested.
