Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to sound-absorbing and noise-reducing porous sintered bricks. Background Technology

[0002] Sintered porous bricks are made from clay, shale, coal gangue, fly ash, silt (river and lake silt), and other solid waste as main raw materials, and are fired. They are mainly used in load-bearing parts of buildings. The bricks are generally rectangular hexahedrons, and the surfaces that bond with mortar should have plaster grooves and mortar grooves to increase the bonding strength.

[0003] Existing sintered porous bricks are stacked together with cement, and the sides of two sintered porous bricks that are in contact with each other are connected with cement. However, when people apply cement to the sintered porous bricks, the cement will fall to the ground because there is no obstruction around it, resulting in waste. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sound-absorbing and noise-reducing porous sintered brick.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sound-absorbing and noise-reducing porous sintered brick, comprising a brick body, a first groove provided on the top surface of the brick body, a plurality of equally spaced through holes penetrating the first groove, a plurality of sound-insulating sleeves vertically provided on the bottom surface of the brick body, a first sealing block provided on the bottom surface of the brick body, and the plurality of sound-insulating sleeves penetrating and fixed to the first sealing block.

[0006] The brick has a second groove on one side and a second sealing block is fixedly connected to the other side.

[0007] The inner wall of the second groove is symmetrically provided with two locking blocks, and the side of the second sealing block is symmetrically provided with two slots that are adapted to the locking blocks.

[0008] The length of the soundproof sleeve is equal to the thickness of the brick, and the top of the soundproof sleeve extends into the through hole.

[0009] The diameter of the through hole is equal to the outer diameter of the soundproof sleeve.

[0010] The brick body and the sound insulation sleeve are an integral structure, and both the sound insulation sleeve and the brick body are made of coal gangue.

[0011] The second sealing block has a vertically oriented guide groove at its center.

[0012] This utility model has the following beneficial effects:

[0013] 1. This sound-absorbing and noise-reducing porous sintered brick features a first groove on the top surface and a first sealing block on the bottom surface, forming a relatively closed cavity when stacked. When mortar is filled into this cavity, its lateral flow is blocked by the groove walls and the block, greatly reducing waste caused by mortar overflowing from the brick joints. This not only saves materials and reduces construction costs but also makes the construction site cleaner and reduces cleaning workload. When sound waves encounter the through holes and sound insulation sleeves inside the brick during propagation, they undergo multiple reflections, refractions, and interferences within these cavities, thus consuming a large amount of sound energy and converting it into heat energy, effectively weakening the sound intensity. The sound insulation sleeves are inserted into the through holes of the lower brick, but they do not fill them tightly; instead, they form a tortuous and complex air channel. Sound waves need to bypass these sleeves and cavities to propagate, making the path extremely tortuous and significantly attenuating the energy during propagation. The unique nested structure of the sound insulation sleeves and through holes increases the path length and number of interfaces for sound waves to propagate inside the brick, improving the damping effect of the entire brick structure and providing good isolation for mid- and low-frequency noise.

[0014] 2. The sound-absorbing and noise-reducing porous sintered brick features a second sealing block and a second groove on the side, along with a locking structure between the locking block and the locking groove. This allows adjacent bricks to be quickly and accurately aligned in the horizontal direction, ensuring the flatness and verticality of the masonry. This mechanical interlocking structure enhances the integrity and stability of the masonry, effectively distributing and bearing loads, and improving the shear strength and seismic performance of the wall. The guide groove on the second sealing block provides an overflow channel for horizontal mortar application. When too much mortar is applied, the excess mortar can be squeezed out along the guide groove, ensuring that the mortar on the brick contact surface is full, uniform, and free of cavities, further guaranteeing the strength of the masonry. It also facilitates worker operation and inspection. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1 to 3 The sound-absorbing and noise-reducing porous sintered brick provided by this utility model includes a brick body 1. The top surface of the brick body 1 is provided with a first groove 2, and multiple equally spaced through holes 3 are provided through the first groove 2. Multiple sound insulation sleeves 6 are vertically provided on the bottom surface of the brick body 1. A first sealing block 7 is provided on the bottom surface of the brick body 1. Multiple sound insulation sleeves 6 are provided through and fixed to the first sealing block 7. A second groove 4 is provided on one side of the brick body 1, and a second sealing block 8 is fixedly connected to the other side. Two locking blocks 5 are symmetrically provided on the inner wall of the second groove 4. Two locking grooves 9 that are adapted to the locking blocks 5 are symmetrically opened on the side of the second sealing block 8. The length of the sound insulation sleeve 6 is equal to the thickness of the brick body 1. The top of the sound insulation sleeve 6 extends into the through hole 3. The diameter of the through hole 3 is equal to the outer diameter of the sound insulation sleeve 6. The brick body 1 and the sound insulation sleeve 6 are an integral structure, and both the sound insulation sleeve 6 and the brick body 1 are made of coal gangue. A guide groove is vertically opened in the center of the second sealing block 8.

[0021] Working principle: During vertical masonry, mortar is applied to the first groove 2 on the top surface of the bottom layer brick 1, so that the mortar surface is flush with the top surface of the first groove 2. Then, the upper layer brick 1 is stacked with the lower layer brick 1, so that the sound insulation sleeve 6 is embedded in the through hole 3 of the lower layer brick 1 and the first sealing block 7 is embedded in the first groove 2. The mortar pre-laid in the first groove 2 of the lower layer brick is squeezed and contained in the space formed by the pit of the first groove 2 and the protrusion of the first sealing block 7. Since there are protruding groove walls and blocks as retaining edges, the mortar is effectively constrained in this space, thereby preventing it from scattering to the surroundings.

[0022] During horizontal masonry, mortar is applied to the second groove 4 on the side of one of the bricks 1, and then the second sealing block 8 on the side of the other brick 1 is installed with the second groove 4 with mortar applied. At the same time, the locking block 5 is engaged with the locking groove 9. Under the pressure of the second sealing block 8, the mortar in the second groove 4 spreads and wraps around the entire exterior of the second sealing block 8. Since there are raised groove walls and blocks around the perimeter as retaining edges, the mortar is effectively constrained within the space, thus preventing it from scattering to the surroundings.

[0023] After the bricks 1 are stacked, the sound insulation sleeve 6 on the bottom surface of the brick will be inserted into the through hole 3 on the top surface of the lower brick. If the sound waves want to propagate from top to bottom or from bottom to top, they must pass through these complex cavity structures formed by the sound insulation sleeve 6 and the through hole 3. The sound waves are repeatedly reflected and transmitted between the air and solid (brick 1, sound insulation sleeve 6) interface. Each interface transition will consume a lot of energy, thereby achieving the purpose of sound insulation. The engagement of the second sealing block 8 and the second groove 4 in the horizontal direction, as well as the mortar filling them, also form an effective sound barrier, blocking the propagation path of the sound along the horizontal mortar joint.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
