Abstract

The utility model relates to an acoustic hanging network body arranged under ceilings of halls and rooms of buildings, comprising an acoustic board and a link piece and forming various network patterns. The acoustic board adopts the structure that a cavity between a frame and a panel with a plurality of holes coating the frame is filled with acoustic materials. The link piece takes a bracket with a slot port as a main body. The link piece with a circular port arranged in the center of the bracket is connected with the acoustic board embedded in the slot port of the bracket by a separating piece, and is fastened by a sealing cover and forms non-exerted steady connection. The acoustic hanging network body has advantages of easy assembly, decorative beauty, various patterns, light weight and fire prevention.

Description

Acoustic hanging network body

A kind of being loaded on as absorbent lined barrier hung the network body under the building Room, the chamber ceiling, belongs to architectural decoration material field.

Acoustical board with monolithic connects in a certain way, and being arranged in the network-like body of hanging is the building and ornament materials that new development is in recent years got up, because of it has sound absorption, printing opacity, the characteristics of beautifying interior decoration are welcome.There is complex structure in prior art, the shortcoming of construction and installation inconvenience.

The purpose of this utility model provides a kind of simple in structure, and is easy to assembly, and the network body is hung in the various sound absorption of pattern.

Used scheme is that acoustical board is made with framework overcoat porous panel, loads the structure of sound absorption material in formation cavity; Connector is there to be the support of notch, and the connection sheet will be contained in the round mouth connector of carriage center and the acoustical board of embedding support notch links together with separating, and upper and lower end is fastening with capping, becomes the firm installation that screw does not expose.

The utlity model has sound absorption function can select, install that many, the concealed construction profile of flower type are attractive in appearance, body gently, fire prevention, advantage applied widely.

This manual has the following drawings.

Fig. 1 hangs schematic diagram for sound absorption network body, shows the triangular net structure;

Fig. 2 is the acoustical board structure;

Fig. 3 is that full sectional view, Fig. 4,5 of connector 2 is its component part figure;

Fig. 6 is the full sectional view that the connector 3 of suspension rod is arranged;

Fig. 7 is that the 7-7 of Fig. 6 analyses and observe.

Now in conjunction with the accompanying drawings.

The utility model by acoustical board 1, connector 2, hang connector 3 and form and see Fig. 1.

Acoustical board 1 is formed the cross section of seeing Fig. 2, panel 4 by panel 4, framework 5, sound absorption material 6 and is become

Shape has sound absorption hole 9 on two side planes, two flangings 7 are arranged at the top, at the intraperitoneal of panel 4 framework 5 are housed, vertically being of framework

Shape is attached thereto whole from the flanging 7 usefulness screws 8 of panel 4.Framework 5 and panel 4 surround a cavity jointly, and sound absorption material 6 is housed in the cavity.The different materials that absorb sound audio frequency of packing into can make acoustical board have different sound absorption functions.

Fig. 3 is seen in the connection of each acoustical board, and the main body of every group of connector 2 is to connect support 10 to see Fig. 4, and support 10 is that the center has circular hole 17, and periphery is connected with the cylindric part of arcuation T shape rib 18, and preferred plan is to be crushed to aluminium.Between per two T shape ribs 18 notch 19 is arranged, the groove number can be 3～8.In the center hole 17 of support 10 upper and lower ends, round mouth connector 11 is housed respectively, fastening with screw 16; Acoustical board 1 embeds in the notch 19 of support 10, Fig. 5 is seen with the connection sheet 13(that separates in two ends) by

screw

14,15 acoustical board 1 and round mouth connector 11 are connected as one (consulting Fig. 7), in the center screw of round mouth connector 11, be screwed into capping 12, capping 12 is the dome-shaped part, and its inner face cavity covers connection sheet 13; Two cappings screw that its periphery of back is pushed down from the top respectively and hold acoustical board 1 from the below, make it become the firm connected node that screw does not expose, each node can be formed acoustical board triangle, right angle type, linear pattern network pattern, need decide on the notch number and the decoration of support 10.

For the network body that will absorb sound is hung under room's ceiling, some connected nodes of network body are equipped with suspension rod 20, and its detailed structure is seen Fig. 6.The lower end major part 21 of suspension rod 20 supporting round mouth connector 11 ' shoulder hole end face 22, thereby supporting the weight of this node place connector and acoustical board.Suspension rod upper end from capping 12 ' centre bore pass, with whole network body overhang in being contained on the channel roof under (on the figure picture).
