Technical Field

[0001] This invention relates to the field of porous brick processing technology, and in particular to a porous brick using vacuum sintering and its firing method. Background Technology

[0002] Porous bricks are a type of concrete product with multiple rows of small holes. They are a new type of wall material following ordinary and lightweight aggregate concrete small hollow blocks. Porous bricks have the characteristics of low production energy consumption, soil conservation and waste utilization, convenient construction, light weight, high strength, good thermal insulation, durability, small shrinkage and deformation, and regular appearance. They are an ideal material to replace sintered clay bricks.

[0003] In the existing technology, porous bricks mostly adopt a rectangular square structure. During the construction process, the connection and positioning between porous bricks usually depends on the judgment of the operator or the use of tools, which is prone to deviation and reduces the quality of construction.

[0004] Therefore, it is necessary to propose a porous brick using vacuum sintering and its firing method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a porous brick using vacuum sintering and its firing method, in order to solve the problem mentioned in the background art that the porous bricks in the prior art mostly adopt a rectangular square structure. During the construction process, the connection and positioning between porous bricks usually depends on the judgment of the operator or the use of tools, which is prone to deviation and reduces the quality of construction.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a porous brick using vacuum sintering, comprising a brick body and a reinforcing frame. Each end of the brick body has a first slot located in the lower half of the brick body, with two first slots staggered. An insert block is engaged with the interior of each first slot. One end of each insert block, located outside the first slot, has an integrally formed protrusion. The protrusion has an L-shaped structure, with two protrusions staggered. The reinforcing frame includes a post and two sets of support frames distributed on either side of the post. Each support frame includes a first connecting block, a second connecting block, and an arc block. Two second connecting blocks and two arc blocks are each provided. The two second connecting blocks are fixedly connected to both ends of the first connecting block. The first connecting block and the two second connecting blocks are arranged in a U-shape. The two arc blocks are distributed correspondingly to the two second connecting blocks. One end of each arc block is fixedly connected to the corresponding second connecting block, and the other end of the second connecting block is fixedly connected to the post. The post, the first connecting block, the second connecting block, and the arc blocks are all fixedly embedded in the bottom of the brick body.

[0007] Preferably, the protruding part has a through groove inside, and the protruding part has a first round hole on both sides, the first round hole communicating with the through groove.

[0008] Preferably, the top of the brick is provided with a square groove, and the inserts are distributed correspondingly to the square groove.

[0009] Preferably, the bottom of the insertion post is provided with a circular groove.

[0010] Preferably, the first connecting block has a second slot inside, the second slot is connected to the corresponding first slot, and the second slot cooperates with the corresponding plug block.

[0011] Preferably, the bottom of the first connecting block, the second connecting block, and the arc block are all provided with multiple grooves.

[0012] Preferably, both ends of the brick are provided with a plurality of second circular holes, which are located inside the reinforcing frame.

[0013] This invention also discloses a method for firing porous bricks using vacuum sintering, comprising the following steps:

[0014] S1. First mixing: The pretreated coal slag, clay, glass powder, material A and water are added to the mixing equipment in sequence to form the first mixture;

[0015] S2. First molding: After the first mixture is stirred evenly, it is sent into the blanking machine to be pressed into a blank of the required size. Then, it is subjected to vacuum sintering to form a reinforcing frame, inserts and protruding parts.

[0016] S3, Second Mixing: The pretreated construction waste, clay, material B and water are added to the mixing equipment in sequence to form the second mixture;

[0017] S4. Second molding: The reinforcing frame is placed in the brick mold, and the second mixture is poured into it. Then, it is pressed and molded. After demolding, it is vacuum sintered to form a porous brick.

[0018] Preferably, material A includes cement, bentonite, and adhesive powder.

[0019] Preferably, the material B comprises plant stalk fragments.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. When two adjacent perforated bricks are connected for construction, the protruding parts of the two perforated bricks at one end are engaged to connect them together, thus completing the horizontal connection and positioning between the perforated bricks, avoiding deviations and improving the quality of construction. At the same time, when the perforated bricks are stacked, the bottom insert of the perforated brick in the upper position is inserted into the square groove of the perforated brick in the lower position, thus completing the vertical connection and positioning between the perforated bricks, avoiding deviations and further improving the quality of construction.

[0022] 2. The protruding parts of two perforated bricks close to each other at one end are interlocked and connected together, which can improve the tightness between adjacent perforated bricks and prevent the phenomenon of gaps appearing at the joint after long-term use, thereby improving the overall construction effect of the wall.

[0023] 3. Set the first round hole and through groove. Cement mortar can pass through the first round hole and through groove for saturation filling, ensuring the filling effect of cement mortar. After the cement mortar is cured, the cured mortar and the two protruding parts are connected to form a whole, further improving the construction effect of the entire wall.

[0024] 4. By setting up a reinforcing frame with greater structural strength and supporting effect in conjunction with the brick body, the structural stability of the porous brick is improved, the strength of the porous brick is enhanced, and a balance between porosity and load-bearing capacity is achieved. At the same time, compared with using the same material for producing the reinforcing frame for the entire porous brick, it also has the effect of saving costs, achieving a balance between production cost and strength of use.

[0025] 5. During the transfer of porous bricks, the bottom insert of the porous brick at the top position is inserted into the square groove of the porous brick at the bottom position to ensure the stability of the porous brick stack and improve the transfer efficiency.

[0026] 6. Apply cement-mixed mortar to the bottom of the insert. Some of the mortar will enter the interior of the circular groove. After the cement-mixed mortar has cured, it will improve the stability of the connection and positioning between the porous bricks in the vertical direction.

[0027] 7. The second circular hole is located inside the reinforcing frame to prevent cement mortar from flowing into the second circular hole, thus ensuring the porous brick's performance in terms of light weight, heat insulation, energy saving, and heat insulation.

[0028] 8. The second circular hole is located inside the reinforcing frame. The reinforcing frame can prevent cement mortar from flowing into the second circular hole and can also reduce the waste of cement mortar, thus achieving the purpose of energy conservation and environmental protection.

[0029] 9. Using waste materials such as coal ash, construction waste, and plant stalk fragments as raw materials is beneficial to environmental protection and achieves the effect of turning waste into treasure. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides, for example Figures 1-6 The diagram shows a porous brick using vacuum sintering, comprising a brick body 1 and a reinforcing frame 15. Both ends of the brick body 1 have first slots 2, located in the lower half of the brick body 1, with the two first slots 2 staggered. An insert block 3 is internally engaged with each first slot 2. One end of the insert block 3, located outside the first slot 2, has an integrally formed protrusion 4. The insert block 3 and the protrusion 4 form a single unit, and the protrusion 4 has an L-shaped structure, with the two protrusions 4 staggered. The first slots 2 are located in the lower half of the brick body 1, ensuring that the protrusion 4 and the insert block 3 are also located in the lower half of the brick body 1. This facilitates better application of cement-mixed mortar to the ends of the porous brick during construction, without affecting normal use.

[0039] Specifically, after the perforated brick is produced and processed, the connector consisting of the insert 3 and the protruding part 4 is separated from the brick body 1, which does not affect the normal stacking and transportation of the perforated brick. At the same time, compared with the protruding part 4 being directly fixed to the outer wall of the brick body 1, it can prevent the protruding part 4 from being easily bumped and broken due to protrusion. Moreover, whether or not it is inserted can be adjusted according to the specific use. For example, the protruding part 4 is not needed at the end of the wall, which increases the flexibility of using perforated brick.

[0040] Before the wall is constructed, the protruding part 4 is inserted into the corresponding first slot 2 through the insert block 3, with the protruding parts 4 at both ends staggered (see reference). Figure 6One right angle turns upwards, and the other right angle turns downwards. When two adjacent perforated bricks are connected, the protruding parts of the two perforated bricks at their closest points are engaged to complete the horizontal connection and positioning between the perforated bricks, avoiding deviations and improving the quality of construction.

[0041] At the same time, the protruding parts of two perforated bricks at one end are connected together by four interlocking parts, which can improve the tightness between adjacent perforated bricks and prevent the phenomenon of gaps appearing at the joint after long-term use, thereby improving the overall construction effect of the wall.

[0042] Then apply cement mortar to the joint to improve its stability.

[0043] To improve the stability of the connection between two adjacent protrusions 4, a through groove 5 is provided inside the protrusion 4, and a first round hole 6 is provided on both sides of the protrusion 4, which is connected to the through groove 5.

[0044] After applying cement-mixed mortar to the joint of two adjacent porous bricks, a first round hole 6 and a through groove 5 are set. The cement-mixed mortar can pass through the first round hole 6 and the through groove 5 to be saturated and filled, ensuring the filling effect of the cement-mixed mortar. After the cement-mixed mortar is cured, the cured mortar and the two protruding parts 4 are connected to form a whole, further improving the construction effect of the entire wall.

[0045] Furthermore, both the insert block 3 and the first slot 2 are provided with anti-slip textured surfaces to improve the stability of the assembly connection;

[0046] In addition, the outer surfaces of the brick body 1, the protruding part 4, and the reinforcing frame 15 are all designed with anti-slip texture (not shown in the figure) to increase the adhesion with the cement mortar.

[0047] The reinforcing frame 15 includes a post 7 and two sets of support frames distributed on both sides of the post 7. Each support frame includes a first connecting block 10, a second connecting block 11, and an arc block 12, with two of each of the second connecting blocks 11 and arc blocks 12. The reinforcing frame 15 has an 8-shaped structure, which expands the support area, ensures support effectiveness, saves materials, and reduces processing costs. The two second connecting blocks 11 are fixedly connected to both ends of the first connecting block 10. To improve the support effect, the first connecting block 10 and the two second connecting blocks 11 are arranged in a U-shape. The two arc blocks 12 are distributed corresponding to the two second connecting blocks 11, with one end of the arc block 12 fixedly connected to the corresponding second connecting block 11, and the other end of the second connecting block 11 fixedly connected to the post 7. The post 7, the first connecting block 10, the second connecting block 11, and the arc blocks 12 are all fixedly embedded in the bottom of the brick body 1.

[0048] Due to the high porosity of porous bricks, and to enhance their structural strength and prevent cracks or bursts during use that could affect the aesthetics and safety of the entire building wall, a reinforcing frame 15 with greater structural strength and supporting effect is installed in conjunction with the brick body 1. This improves the structural stability of the porous bricks, enhances their strength, and achieves a balance between porosity and load-bearing capacity.

[0049] At the same time, compared with using the same material for the reinforced frame 15 in the production of porous bricks, it also has the effect of saving costs and achieving a balance between production costs and strength.

[0050] Considering the stability of the porous bricks during the stacking and transportation process, a square groove 9 is provided on the top of the brick body 1, and the inserted columns 7 are distributed correspondingly to the square groove 9.

[0051] Specifically, when the upper and lower layers are stacked, the bottom of the perforated brick at the top position is inserted into the square groove 9 of the perforated brick at the bottom position, which completes the vertical connection and positioning between the perforated bricks, avoids deviation, and further improves the quality of construction.

[0052] Similarly, during the transfer of porous bricks, the bottom insert 7 of the porous brick in the upper position is inserted into the square groove 9 of the porous brick in the lower position to ensure the stability of the porous brick stack and improve the transfer efficiency.

[0053] Furthermore, even when the bottom layer of porous bricks is in direct contact with a flat surface such as the ground, cement-mixed mortar is applied to the four edges of the lower surface of the porous bricks, with a thickness exceeding the height of the protruding post 7, so that the protruding post 7 will not affect the normal use of the porous bricks.

[0054] To improve the stability of the insertion post 7 when inserted into the square groove 9, a circular groove 8 is provided at the bottom of the insertion post 7.

[0055] Specifically, during the masonry process, cement-mixed mortar is applied to the bottom of the insert column 7. Some of the mortar will enter the interior of the circular groove 8. After the cement-mixed mortar has cured, it will improve the stability of the connection and positioning between the porous bricks in the vertical direction.

[0056] The first connecting block 10 has a second slot 13 inside, which is connected to the corresponding first slot 2. The second slot 13 cooperates with the corresponding insert block 3 to improve the stability of the connection between the protruding part 4 and the brick body 1 and the reinforcing frame 15.

[0057] The bottoms of the first connecting block 10, the second connecting block 11, and the arc block 12 are all provided with multiple grooves 14. The grooves 14 can be triangular, semi-circular, or other structures, and can be adjusted according to the specific application. The grooves 14 are provided to increase the contact area between the bottom of the reinforcing frame 15 and the cement mortar.

[0058] In practical use, cement-mixed mortar is applied to the four edges of the lower surface of the porous brick and adhered to the outer wall of the reinforcing frame 15. When the porous brick is pressed down on the lower part of the brick, the cement-mixed mortar will seep into the groove 14. The groove 14 increases the contact area between the bottom of the reinforcing frame 15 and the cement-mixed mortar, increases the stability of the connection between the reinforcing frame 15 and the cement-mixed mortar, and further improves the stability of the vertical connection and positioning between the porous bricks.

[0059] Several second circular holes 16 are provided at both ends of the brick body 1. The second circular holes 16 penetrate the brick body 1 and are located inside the reinforcing frame 15. The second circular holes 16 have functions such as heat insulation, sound insulation and heat preservation. The second circular holes 16 are the holes of porous bricks in the prior art. The holes of porous bricks are a common technology in the present technology and will not be described in detail here.

[0060] In addition, the second round hole 16 is located inside the reinforcing frame 15 to prevent cement mortar from flowing into the interior of the second round hole 16, thus ensuring the effectiveness of the porous brick in terms of light weight, heat preservation and energy saving, and heat insulation.

[0061] Meanwhile, the second round hole 16 is located inside the reinforcing frame 15. The reinforcing frame 15 can prevent cement mortar from flowing into the second round hole 16 and can also reduce the waste of cement mortar, thus achieving the purpose of energy conservation and environmental protection.

[0062] This invention also includes a method for firing porous bricks using vacuum sintering:

[0063] S1. First mixing: The pretreated coal slag, clay, glass powder, material A and water are added to the mixing equipment in sequence to form the first mixture;

[0064] Using coal slag can effectively treat and utilize industrial solid waste, achieving the goal of environmental protection.

[0065] Considering that the reinforcing frame 15 is used to strengthen the structural strength of the porous bricks, and the protruding part 4 is used for connection and positioning between adjacent porous bricks, both require increased strength. Therefore, the materials used for the reinforcing frame 15 and the protruding part 4 include cinder, clay, glass powder, and component A. Component A includes cement, bentonite, and adhesive powder.

[0066] Glass powder, cement, tungsten clay, and adhesive powder are all used to enhance the bonding performance and strength between the raw materials of the reinforcing frame 15 and the protruding part 4, thereby improving the crack resistance and service strength of the reinforcing frame 15 and the protruding part 4.

[0067] In practical applications, the pretreatment of raw materials such as coal slag, clay, and glass powder includes crushing, screening, and proportioning, which can be adjusted according to specific application conditions. Crushing, screening, and proportioning are all common existing technologies and will not be elaborated upon here.

[0068] S2. First molding: After the first mixture is stirred evenly, it is sent into the blanking machine to be pressed into a blank of the required size. Then, it is subjected to vacuum sintering to form a reinforcing frame 15, insert block 3 and protruding part 4.

[0069] Vacuum sintering can be performed using a vacuum sintering furnace, thereby increasing the density of the reinforced frame 15 and the protrusion 4.

[0070] S3, Second Mixing: The pretreated construction waste, clay, material B and water are added to the mixing equipment in sequence to form the second mixture;

[0071] Material B includes plant stalk fragments, which can be one or more of rice straw, wheat straw, or discarded banana stalks, but are not limited to. Plant stalk fragments have a certain heat insulation effect, which increases the heat insulation performance of porous bricks and also improves the durability of porous bricks.

[0072] Using construction waste, plant stalk fragments, and other waste materials as raw materials is beneficial to environmental protection and achieves the effect of turning waste into treasure.

[0073] In practical applications, the pretreatment of raw materials such as construction waste and clay includes crushing, screening, and proportioning, which can be adjusted according to specific usage conditions. Crushing, screening, and proportioning are all common existing technologies and will not be elaborated upon here.

[0074] S4. Second molding: Place the reinforcing frame 15 into the brick body 1 mold, pour the evenly mixed second mixture into it, then press it into shape, demold it and perform vacuum sintering to form a porous brick.

[0075] Vacuum sintering can be performed using a vacuum sintering furnace, thereby increasing the density of porous bricks.
