DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] The utility model provides Figure 1 to Figure 5A porous brick with sound insulation effect shown in the figure comprises a main body 1 and an inner frame 2. A through hole 8 is provided through the main body 1. The through hole 8 is arranged in a plurality to form a porous structure. The inner frame 2 comprises an extension block 3 and a trapezoidal body 4. The trapezoidal body 4 is arranged in two. The extension block 3 and the two trapezoidal bodies 4 are formed by an integrated molding process. The height of the extension block 3 is greater than the height of the trapezoidal body 4. A trapezoidal structure is formed between the trapezoidal body 4 and the extension block 3. The width of the end close to the extension block 3 is small, forming a supporting structure with strong supporting force, so that the porous brick is not easy to break. A through groove 6 is provided through the inside of the main body 1. The through groove 6 is located in the middle position of the main body 1. The extension block 3 is arranged inside the through groove 6. Positioning grooves 7 are provided at both ends of the main body 1. The two positioning grooves 7 are connected to the through groove 6. The two trapezoidal bodies 4 are respectively arranged inside the two positioning grooves 7. The extension block 3 and the trapezoidal body 4 both extend out of the main body 1.
[0022] In specific use, the porous brick can be formed twice. The first forming: raw materials such as coal slag and clay are mixed and stirred, and made into a blank, which is then vacuum sintered to form an inner frame 2; the second forming: raw materials such as slag and clay are mixed and stirred to form a slurry, which is placed in a forming mold together with the inner frame 2, and vacuum sintered for the second time to form a porous brick.
[0023] The strength of the inner frame 2 is greater than that of the main body 1, so that the cost can be saved while ensuring the overall strength of the porous bricks.
[0024] When stacking the porous bricks in an offset manner, cement mortar is applied to the bottom of the porous bricks and covers the inner frame 2, which can enhance the connection strength between the cement mortar and the porous bricks, thereby improving the strength of the porous bricks stacked up and down.
[0025] At the same time, there is no docking structure at the joints of the traditional porous bricks. The mutual alignment of the porous bricks depends on the experience of the construction workers, which easily leads to misalignment of the porous bricks. Secondary leveling is required in the later stage, thus affecting the overall construction efficiency. Since the through groove 6 is opened through the main body 1, the extension block 3 can be used as a mark, so that the porous bricks at the upper layer are pressed between the two porous bricks at the lower layer (refer to Figure 2 ), that is: the ends of the porous bricks at the upper layer correspond to 3 porous brick extension blocks at the lower layer, so as to avoid the deviation of the porous bricks, improve the efficiency of the splicing of the porous bricks, and improve the aesthetics at the same time.
[0026] By setting the porous bricks as the main body 1 and the inner frame 2, the purpose of cost saving is achieved while ensuring the overall strength of the porous bricks; and the connection strength between the cement mortar and the porous bricks can be enhanced, thereby improving the strength of the porous bricks when stacked up and down; at the same time, the porous bricks are prevented from shifting during the stacking process, thereby improving the efficiency and aesthetics of the porous brick splicing.
[0027] A groove 5 is provided at the bottom of the trapezoidal body 4, and a plurality of grooves 5 are provided. The grooves 5 are provided to increase the friction force of the inner frame 2 and improve the connection strength between the inner frame 2 and the cement mortar.
[0028] Square grooves 9 are formed through both sides of the main body 1 , and a protective plate 10 is inserted into the inside of the square groove 9 . The protective plate 10 is formed by pressing a rock wool board layer 11 , a sound insulation felt layer 12 and a heat insulation wool layer 13 .
[0029] The rock wool board layer 11 can be made of but not limited to rock wool board material, and has good thermal insulation, fire resistance and sound absorption performance; the sound insulation felt layer 12 is made of elastic materials such as rubber and plastic, and has sound insulation performance; the thermal insulation cotton layer 13 is made of thermal insulation cotton material and has a thermal insulation effect.
[0030] By providing the protection plate 10, which is formed by pressing together a rock wool board layer 11, a sound insulation felt layer 12 and a heat insulation wool layer 13, the porous brick has the properties of sound insulation, heat preservation, fire resistance and sound absorption.
