Description
Technical field
The present invention relates to architectural decoration construction field, particularly relate to a kind of decoration sound-absorbent wall.
Background technology
Along with Large conference center, the construction of theater arenas gets more and more, also more and more higher to the requirement of decorative effect, and existing sound-absorbent wall way mostly commercially is the flat board of perforation, or increasing ornamental strip etc., decorative effect is single stiff, can not meet the demand of social development.
Meanwhile, the abatvoix of general construction metope mostly is wet combining operation, is unfavorable for adjustment degree of plainness for wall surface and the repair and replacement in later stage.
In addition, common decorated wall surface moulding is enriched, but the design of various moulding is often difficult to good acoustical behavior, and arenas, conference centre's sound dffusion can be caused bad.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of decoration sound-absorbent wall, can promote indoor decorative effect, and can solve the problem of absorbing sound and lowering noise.
The present invention for solving the problems of the technologies described above adopted technical scheme is:
A kind of decoration sound-absorbent wall, comprise decoration acoustic panel, described decoration acoustic panel is divided into four layers, is followed successively by steel sole plate, glass wool board, wooden perforated sound-absorbing plate and wooden lagging cylinder non-metallic refractory from inside to outside.
Described decoration acoustic panel back is fixed on angle steel, and angle steel welds with vertical channel-section steel, and vertical channel-section steel welds with the transverse channel steels perpendicular to metope, and transverse channel steels is welded on steel plate, and steel plate is fixed on metope by expansion bolt.
Described glass wool board, wooden perforated sound-absorbing plate and wooden lagging cylinder non-metallic refractory are secured by bolts in steel sole plate front; The steel sole plate back side is provided with several metal hangers.
Described angle steel and metal hanger are fixed.
Described vertical channel-section steel side with and the angle steel fixing with metal hanger weld.
Described vertical slot steel backing face is welded on the short channel-section steel perpendicular to metope; Described short channel-section steel end is welded on steel plate, and described steel plate is fixed on metope by expansion bolt.
Sound-absorbing cloth is surrounded by outside described glass wool board.

Wherein, 1-decoration acoustic panel, 2-steel sole plate, 3-glass wool board, the wooden perforated sound-absorbing plate of 4-, 5-wood lagging cylinder non-metallic refractory, the vertical channel-section steel of 6-, 7-expansion bolt, 8-bolt, 9-metal hanger, the horizontal angle steel of 10-, the short channel-section steel of 11-, 12-steel plate, 13-bores a hole, 14-body of wall
Detailed description of the invention
One decoration sound-absorbent wall as depicted in figs. 1 and 2, comprise decoration acoustic panel 1, described decoration acoustic panel 1 is divided into four layers, is followed successively by steel sole plate 2, glass wool board 3, wooden perforated sound-absorbing plate 4 and wooden lagging cylinder non-metallic refractory 5 from inside to outside; Described decoration acoustic panel 1 back is fixed on angle steel 10 by metal hanger 9, angle steel 10 welds with vertical channel-section steel 6, vertical channel-section steel 6 welds with the short channel-section steel 11 of transverse direction perpendicular to metope, and laterally short channel-section steel 11 is welded on steel plate 12, and steel plate 12 is fixed on metope 14 by expansion bolt 7.
The composite design that this decoration acoustic panel adopts multiple sound-absorbing to design makes this metope have good sound-absorbing erasure effect, the wooden lagging cylinder non-metallic refractory of external surface then changes the design of the stiff and free sound field regulatory function of sound-absorbent wall in the past, makes it to have attractive in appearance and utility function concurrently.
Glass wool board 3, wooden perforated sound-absorbing plate 4 and wooden lagging cylinder non-metallic refractory 5 are fixed on steel sole plate 2 front by bolt 8, composition decoration acoustic panel 1.This metope adopts multiple sound-absorbing to design sheet material, the sound-absorbing principle of wooden perforated sound-absorbing plate 4 is sound waves by the hole of the inner small in a large number connection of abatvoix circular hole, go deep into material internal along these holes, with material generation rubbing action, acoustic energy is converted into heat energy, thus plays the effect of sound-absorbing.
Wood lagging cylinder non-metallic refractory 5 can utilize the surface of cylinder to carry out diffuse reflection to sound wave, reduces echo; Steel sole plate 2 back side is provided with several metal hangers 9, is fixed by metal hanger 9 and horizontal angle steel 10.
Because steel sole plate 2 is also the transversely arranged of piecemeal, be convenient to the fixing of decoration acoustic panel 1 like this; Vertical channel-section steel 6 side is welded with horizontal angle steel 10, and described angle steel 10 is fixed by bolt 8 with metal hanger 9.Vertical channel-section steel 6 back side is welded on the short channel-section steel 11 perpendicular to metope; Described short channel-section steel 11 end is welded on steel plate 12, and described steel plate 12 is fixed on metope by expansion bolt 7.
Be surrounded by sound-absorbing cloth outside glass wool board 3, sound-absorbing cloth is processed into according to Principles of Acoustics, is a kind of special soundabsorbing textured material for the field that absorbs sound by force, adopt the forming materials cutting of porous fibrous, more effective to the absorption of low frequency, can standing wave be eliminated, reach the requirement of stopping echo.
Decoration acoustic panel 1 is also by steel sheet bound edge, and the reason of bound edge increases monolithic abatvoix frame intensity, is attractive in appearancely convenient to installation forming simultaneously.
Wood lagging cylinder non-metallic refractory 5 inside is fine and close wood fiber structure, also has good texture, fire-resistant, sound reflection performance, and has certain intensity.
As shown in Figure 3 wooden perforated sound-absorbing plate 4 has the perforation 13 of regular array, the sound-absorbing principle of the perforation of this shape Sum fanction arrangement is sound wave by the hole of the inner small in a large number connection of circular hole, go deep into material internal along these holes, with material generation rubbing action, acoustic energy is converted into heat energy.Thus play the effect of sound-absorbing.
The installation steps of decoration sound-absorbent wall are as follows:
(1) channel-section steel is installed: fix galvanized steel plain sheet 12 by expansion bolt 7 and be connected to metope.Vertical channel-section steel 6 is connected with steel plate 12 by the short channel-section steel 11 of vertical wall.
(2) horizontal angle steel 10 welds: the weld spacing of described horizontal angle steel 10 should be determined according to the height of described decoration acoustic panel 1.
(3) decoration acoustic panel 1 is installed: when described decoration acoustic panel 1 is installed, and be arranged on described angle steel 10 by described metal hanger 9, every block decoration acoustic panel 1 at least needs four metal hangers 9.
Should be understood that, above-mentioned detailed description of the invention of the present invention only for exemplary illustration or explain principle of the present invention, and is not construed as limiting the invention.Therefore, any amendment made when without departing from the spirit and scope of the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.In addition, claims of the present invention be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
