Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rock wool boards, and particularly relates to a noise-reducing, sound-absorbing and fire-proof rock wool board. Background Art
[0002] Rock wool boards are mainly composed of inorganic fibers made from natural rocks (such as basalt, limestone, coal gangue, etc.) after being melted at high temperatures. These natural rocks are melted into magma at high temperatures and then stretched into fine filaments by a spinning machine rotating at high speed, and finally form rock wool fibers, which are further processed into boards to become high-quality building materials. There are many types of rock wool boards, and the noise-reducing, sound-absorbing and fire-proof rock wool board is an important part of them;
[0003] Due to the low strength of the existing rock wool boards, they are prone to deformation during use, resulting in a short service life. In addition, the noise reduction method is relatively single, resulting in poor noise reduction performance and low applicability during use. Content of the Utility Model
[0004] The purpose of the utility model is to provide a noise-reducing, sound-absorbing and fire-proof rock wool board to solve the defects of the existing rock wool boards with low strength and single noise reduction method.
[0005] To solve the above technical problems, the utility model provides the following technical solution: a noise-reducing, sound-absorbing and fire-proof rock wool board, including a frame;
[0006] On one side inside the frame, a strengthening structure is arranged. The strengthening structure includes a first skeleton, a second skeleton, a first connection groove and a second connection groove. The first skeleton is evenly arranged on one side inside the frame. On both sides of the top of the first skeleton, first connection grooves are opened. Inside the first connection grooves, second skeletons are arranged. On the bottom of the second skeletons, second connection grooves are evenly opened. Rock wool layers are filled on one side of the first skeleton and the second skeleton. On the side inside the frame away from the first skeleton, a noise reduction structure is fixed;
[0007] On the outer walls on both sides of the frame, a splicing structure is fixed;
[0008] On the top of the frame, a fiberglass mesh cloth is arranged. On the top of the fiberglass mesh cloth, an adhesive layer is arranged. On the top of the adhesive layer, a back plate is fixed. On the top of the back plate, a coating layer is adhered.
[0009] Preferably, the first skeletons are equally spaced on the inner side of the frame, and the first skeleton and the second skeleton are perpendicularly distributed through the first connection groove and the second connection groove.
[0010] Preferably, the noise reduction structure includes a sound-absorbing cotton, a first orifice plate, a second orifice plate, sound holes, and turbulence holes. The first orifice plate is fixed to the side of the frame away from the first skeleton. Second orifice plates are fixedly arranged inside the frames on both sides of the first orifice plate. The sound-absorbing cotton is filled on the side of the rock wool layer close to the second orifice plate. Turbulence holes are evenly arranged inside the first orifice plate, and sound holes are evenly arranged inside the second orifice plate.
[0011] Preferably, one side of the second orifice plate is attached to one side of the first skeleton and the second skeleton. The turbulence holes are evenly distributed inside the first orifice plate. The central axes of the sound holes and the turbulence holes are collinear. The inner diameter of the sound holes is smaller than that of the turbulence holes.
[0012] Preferably, the splicing structure includes a protective plate, grooves, clamping grooves, connecting plates, and clamping blocks. The clamping grooves are evenly formed on the outer wall of one side of the frame. Grooves are formed inside the frames on both sides of the clamping grooves. The protective plates are evenly fixed on the outer wall of the other side of the frame. Connecting plates are fixedly arranged on the outer walls of one side of the protective plates. Clamping blocks are fixedly arranged on the outer walls of the connecting plates away from the frames.
[0013] Preferably, the protective plate and the frame are in interference fit through the grooves, and the clamping blocks and the frame form a clamping structure through the clamping grooves.
[0014] Preferably, the length dimension of the protective plate is greater than that of the connecting plate, and the width dimension of the protective plate is smaller than that of the connecting plate.
[0015] The advantages of a noise reduction, sound absorption, and fireproof rock wool board provided by the present utility model are as follows:
[0016] By providing a strengthening structure, the first skeletons are fixed at equal intervals on one side inside the frame. Through the cooperation of the first connecting grooves and the second connecting grooves, the second skeletons are clamped on both sides of the first skeletons. The first skeletons and the second skeletons are vertically distributed, enhancing the strength of the rock wool board, avoiding deformation of the rock wool board during use, and thus extending the service life of the rock wool board.
[0017] By providing a noise reduction structure, sound-absorbing cotton is filled on one side of the rock wool layer. Then, the first orifice plate and two groups of second orifice plates are moved to one side of the sound-absorbing cotton, with the first orifice plate located between the two groups of second orifice plates, and the outer side walls of the first orifice plate and the second orifice plates are fixedly connected to the inner side walls of the frame. The inner diameter of the sound holes is smaller than that of the turbulence holes. When noise enters the interior of the turbulence holes through the sound holes, sound waves will scatter inside the turbulence holes, effectively preventing the direct propagation of sound waves, reducing the penetration and transmission of noise. Under the action of the sound-absorbing cotton, the sound waves will be secondarily absorbed, greatly improving the noise reduction and sound absorption performance of the rock wool board, and thus enhancing the applicability of the rock wool board during use.
[0018] By setting a splicing structure, when splicing two groups of frames, the connecting plate moves into the clamping groove, so that the clamping block and the frame are clamped with each other through the clamping groove. At the same time, the protection plate will move into the groove. Under the action of the protection plate, the stability of the clamping state of the clamping block is enhanced. And the length dimension of the protection plate is greater than the length dimension of the connecting plate, and the width dimension of the protection plate is smaller than the width dimension of the connecting plate. During the transportation of the rock wool board, the connecting plate and the clamping block will not be damaged under the protection of the protection plate, realizing the function of the device being easy to splice, thereby improving the convenience of the rock wool board in use;
[0019] By setting a rock wool layer, the space formed by the first skeleton and the second skeleton is filled with the rock wool layer. The rock wool layer can effectively prevent the spread of fire and maintain the structural stability at high temperatures, making the rock wool board have excellent fire prevention performance, protecting life and property safety, thereby improving the safety of the rock wool board in use.
