Abstract
A perlite acoustic board joint structure is characterized by comprising a lower acoustic board, an upper acoustic board and a sealing gasket, wherein the lower acoustic board is provided with an upper-end joint projection, the upper acoustic board is provided with an inner groove with a lower-end joint matching with the projection of the lower acoustic board, the sealing gasket is arranged between the upper acoustic board and the lower acoustic board which are spliced by the aid of the projection and the groove, and the sealing gasket is a middle joint. The perlite acoustic board joint structure not only solves the problems of larger gaps, misplacement, inconvenience in maintenance and the like of perlite acoustic board joints, but also simplifies installation, ensures installation precision, facilitates batch production, has properties such as fine drainage performance and the like, and greatly improves acoustic insulation and absorption effects of the acoustic boards.
Description
Technical field
The utility model belongs to road noise and administers technical field, particularly acoustical board seam construction.
Background technology
The perlite acoustical board is the chadless building material that is processed by raw material such as perlite, inorganic bond, gauze wire cloths.This product has multiple functions such as sound absorption high-efficiency broad spectrum, fire prevention, water-fast, insulation, light weight, environmental protection, non-secondary pollution be easy to use.It is mainly used in road noise improvement, industrial noise improvement, interior decoration sound absorption and does the machine room theater and paste sound absorptions such as wall slab.
The perlite acoustical board is used for road noise to be administered, and its form of structure is: panel boring communicates with die cavity, and inner chamber placement sound absorption material can more effectively play like this every, sound absorption.Because when the perlite acoustical board is used for road noise improvement, the general requirements acoustical board will reach a certain height, but the acoustical board of making the big specification of engineering demands is to consider it also is inconvenient, unscientific from factors such as carrying, installation, performance intensity, so just need polylith is connected bond to reach desired height than the acoustical board of small-sized.With several modes that are connected than the acoustical board up and down of small-sized, other traditional ways have: a kind ofly be, the interface of acoustical board all adopts smoothed version, and another kind is that the interface of acoustical board all adopts the indent form.First kind of acoustical board (as Fig. 1) that the seam mode is formed, I, II two boards joining place not only have bigger slit, and occur dislocation easily between two boards.Because joining place has bigger slit, though placed sealing mat [III], still be easier to entrant sound relatively and weakened sound-absorbing effect greatly, in addition as seal the problem that inconvenient maintenance can appear again in this slit with cement paste because the slit is inhomogeneous; Second kind of seam mode formed acoustical board (as Fig. 2), A, B two boards centering stack and fill out cement mortar to reach firm effect in the groove of two boards, though this bridging mode can reduce the dislocation tolerance between two boards, but cement mortar is solidified the difficult dismounting in back, also can bring the problem of repair and replacement inconvenience.
Summary of the invention
Research purpose of the present utility model is the phenomenon that solves big, the easy entrant sound in the perlite acoustical board seam slit of using on the road, appearance dislocation, inconvenient maintenance, and has realized the installation simple and convenient, reaches the production and the mounting process of high quality and high efficiency.
The utility model is made up of the following acoustical board of last abutted seam projection, the last acoustical board of the inner groovy that is complementary of abutted seam and following acoustical board projection, and the sealing mat between the upper and lower acoustical board down, and that upper and lower acoustical board passes through is protruding, groove splices, and the centre joint is a sealing mat.
Installation process of the present utility model is: after down acoustical board installed, the inner groovy position that only needs to go up acoustical board was over against the projection position of acoustical board down, and placed sealing mat between upper and lower acoustical board, can reach gap sealing, firm, draining effect smoothly.
The utility model has not only solved the problem that perlite acoustical board seam slit is big, dislocation, inconvenient maintenance etc. occur, also easy installation, guarantee installation accuracy, conveniently produce, have characteristic such as good water drainage property in batches, improved greatly simultaneously acoustical board every, acoustically effective.
Description of drawings
Fig. 1 is the structural representation of a kind of acoustical board seam mode cross section of the prior art, and the interface of acoustical board all adopts smoothed version, and wherein I is that acoustical board, II are that last acoustical board, III are sealing mat down.
Fig. 2 is the structural representation of another kind of acoustical board seam mode cross section of the prior art, and the interface of acoustical board all adopts the indent form, and wherein A is that acoustical board, B are that last acoustical board, C are the filling concrete mortar down.
Fig. 3 is the structural representation of the cross section of a kind of embodiment of the utility model, and the interface of two acoustical boards is respectively a recessed convex formula, and 1 is that acoustical board, 2 is that last acoustical board, 3 is sealing mat down.
The specific embodiment
Below in conjunction with drawings and Examples utility model is further described.
As shown in Figure 3, protruding, the recessed structure of the seam of the described employing of present embodiment is an arc structure.
Specifically, the described seam construction of present embodiment adopts the following acoustical board (1) of going up abutted seam circular arc projection, the structure that the last acoustical board (2) of following abutted seam circular arc indent and sealing mat (3) are formed.Following acoustical board (1) is gone up abutted seam and is had the circular arc projection, and last acoustical board (2) abutted seam down has the arc groove that is complementary with following acoustical board (1) circular arc projection, between the upper and lower acoustical board sealing mat is set.After down acoustical board (1) installed, the inner groovy position that only needs to go up acoustical board (2) was over against the projection position of acoustical board (1) down, and placed sealing mat (3) between upper and lower acoustical board, can reach gap sealing, firm, draining effect smoothly.The prefabricated circular arc projection of acoustical board (1), following acoustical board (2) arc groove gone up when producing such acoustical board.
When the fruit engineering needs three or more acoustical boards to form, then keep the even surface except that the lower end of bottommost acoustical board and the upper end of topmost acoustical board, the upper/lower terminal of all the other acoustical boards all needs become a recessed convex formula according to actual fabrication.In the construction and installation process, need recognize bottommost and the corresponding acoustical board of topmost earlier, all the other acoustical boards if from lower to upper seam be in proper order " bottom even surface---male and female face---male and fomale(M﹠F) ...---the top even surface " get final product.
The seam construction of the utility model embodiment, repair and replacement are convenient, drainage performance is good, simple installation is easily spent, the tolerance that misplaces is little.
Claims (2)
1. perlite acoustical board seam construction, it is characterized in that by the following acoustical board of last abutted seam projection, the last acoustical board of the inner groovy that is complementary of abutted seam and following acoustical board projection down, and the sealing mat between the upper and lower acoustical board is formed, upper and lower acoustical board is by protruding, groove splicing, and the centre joint is a sealing mat.
2. seam construction according to claim 1 is characterized in that described protruding, groove is an arc structure.
