DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the present invention, reference is made to Figure 1 - Figure 6 As shown: a lightweight anti-cracking autoclaved aerated concrete block, comprising a block body 1, the block body 1 is composed of a polymer modified cement mortar layer 11, a concrete main body layer 12, an aerated concrete layer 13 and a wear-resistant buffer layer 14; The polymer modified cement mortar layer 11 is located on the top surface of the concrete main body layer 12 and is used to form a high-toughness and high-strength protective layer on the surface of the block body 1; The concrete main body layer 12 and the aerated concrete layer 13 are cast by first casting the concrete main body layer 12, and then casting the aerated concrete layer 13 when the concrete is still in a plastic state that is not completely solidified, so that they form an integrated casting; The wear-resistant buffer layer 14 is located at the bottom of the aerated concrete layer 13, and is used to add rubber particles in the aerated concrete layer when the aerated concrete layer is in a plastic state that is not completely solidified; The four corners of the block body 1 are bonded with corner protection plates 6, and the side protection components 8 are installed inside the corner protection plates 6. After the side protection components 8 are installed inside the corner protection plates 6, they are formed into a whole by pouring concrete. The side protection component 8 includes a right-angle reinforcement anchor 81, and the left and right ends of the right-angle reinforcement anchor 81 are sleeved with a repair agent capsule 82. The surface of the repair agent capsule 82 is penetrated by a repair path cavity 83, and the side of the repair path cavity 83 is connected to the corner repair path cavity 84. A buffer elastic rod 85 is fastened to the right-angle intersection of the right-angle reinforcement anchor 81, and a plurality of groups of stress arc plates 86 are evenly divided and equidistantly installed on the outside of the buffer elastic rod 85. The front end group of stress arc plates 86 are embedded in the outer corner of the corner protection plate 6, and the sides of the middle group of stress arc plates 86 are in contact with the outer wall surface of the repair agent capsule 82.

[0021] In a specific scheme, the main concrete layer is poured: first, the main concrete layer 12 is poured in a mold, and when the main concrete layer 12 is in a plastic state that is not completely solidified, the aerated concrete layer 13 is poured immediately, so that it is evenly spread on the main concrete layer 12 and gradually expands and emits gas to form an aerated concrete layer 13 with a porous structure, so that the aerated concrete layer 13 can be tightly combined with the lower main concrete layer 12 to form an integrated structure, and when the aerated concrete layer 13 is not completely solidified and is in a plastic state, rubber particles are evenly added to its bottom to form a wear-resistant buffer layer 14, and the rubber particles are used to enhance the wear resistance of the bottom of the block. The abrasive and buffering properties can reduce the damage caused by friction and collision during use. Then, after the concrete main layer 12 and the aerated concrete layer 13 are initially solidified, a polymer modified cement mortar layer 11 is applied to the top surface of the concrete main layer 12 to form a high toughness and high strength protective layer. Then, pre-made corner protection plates 6 are placed at the four corners of the block body 1, and the side protection components 8 are installed inside the corner protection plates 6. The right-angle reinforcement anchor bolts 81 pass through the reserved holes on the corner protection plates 6 so that their right-angle intersections are located at appropriate positions at the corners. Then, repair agent capsules 82 are set at the left and right ends, and the buffer elastic rods 85 are connected to the right-angle reinforcement anchor bolts 81. The right-angle intersection of the anchor bolt 81 is fastened and connected, and multiple groups of stress arc plates 86 are installed on the outside of the buffer elastic rod 85, so that the front group of stress arc plates 86 are embedded in the outer corner of the corner protection plate 6, and the middle group of stress arc plates 86 are in contact with the outer wall surface of the repair agent capsule 82. Finally, by pouring concrete in the corner protection plate 6, the side protection component 8 and the corner protection plate 6 are formed into a whole, so that the entire corner protection structure is fastened to the block body 1. During use, the polymer modified cement mortar layer 11 is used to resist external erosion and slight collisions, protect the internal concrete main layer 12 and the aerated concrete layer 13, and reduce the wear-resistant buffer layer 14. Friction damage caused by the ground or other supporting structures. When the corners of the block body 1 are damaged by a large external force or other reasons, the external force first acts on the corner protection plate 6, and the corner protection plate 6 transfers part of the impact force to the buffer elastic rod 85, so that the buffer elastic rod 85 is compressed, absorbing part of the energy, reducing the direct impact on the block body 1, and when the impact force is too large, the stress arc plate 86 causes the repair agent capsule 82 to rupture, and the repair agent flows out and fills along the repair path cavity 83 and the corner repair path cavity 84, so that it is easy to solidify in the air or after reacting with the block material, thereby achieving self-repair and restoring some strength and integrity of the corners.

[0022] In the present invention, according to Figure 1 - Figure 3As shown, the top and bottom ends of the inner part of the block body 1 are symmetrically provided with first anti-stress ventilation holes 3 and second anti-stress ventilation holes 4, respectively. The first anti-stress ventilation holes 3 and the second anti-stress ventilation holes 4 are used to arrange the pores generated inside along a specific direction using an open-hole mold during the autoclaving process of the block body 1 to form a honeycomb structure.

[0023] A reinforcement frame 5 is embedded and bonded in the middle of the block body 1, and multiple groups of bearing components 9 are equally installed inside the reinforcement frame 5. After the multiple groups of bearing components 9 are installed inside the reinforcement frame 5, they are formed into a whole by pouring concrete.

[0024] The bearing assembly 9 comprises a reinforcing head 91 , the bottom of the reinforcing head 91 is fastened with a bearing cavity sleeve 93 , and the two sides of the bearing cavity sleeve 93 are fastened with bearing support plates 92 .

[0025] The bottom end of the bearing cavity sleeve 93 is fastened with a reinforcing bolt cone 94 , the interior of the bearing cavity sleeve 93 is filled with helium, and the top of the reinforcing plug 91 and the bottom of the reinforcing bolt cone 94 are both inserted into the concrete of the block body 1 .

[0026] In a specific solution, a mold specially used for forming the openings of the first anti-stress vent holes 3 and the second anti-stress vent holes 4 is used, so that the mold can be accurately positioned at the corresponding positions of the top and bottom ends inside the block body 1, and has a structural guide channel for guiding the directional arrangement of the pores during the autoclaving process, so that the prepared concrete raw materials are injected into the block mold with the opening mold installed. During the pouring process, the concrete is evenly distributed in the mold. Then the block mold containing the concrete and the opening mold is placed in an autoclave for autoclaving. Under high temperature and high pressure, a series of physical and chemical reactions occur inside the concrete, generating gas and forming pores, so that these pores are gradually arranged along the direction set by the mold during the formation process, and finally forming the first anti-stress vent holes 3 and the second anti-stress vent holes 4 of the honeycomb structure. After the autoclaving is completed, a reinforcement frame 5 is prepared according to the size of the block, and then it is placed in the middle position of the mold of the block body 1 and preliminarily fixed. Ensure that its position is accurate and will not be displaced during the subsequent pouring process. The setting of the bearing component 9 enables the reinforcement head 91 to be tightly connected with the bearing cavity sleeve 93 to ensure a firm connection and good sealing to prevent leakage of the helium filled inside. Then, the bearing support plate 92 is installed on the two sides of the bearing cavity sleeve 93 to also ensure the stability of the connection. Finally, the reinforcement bolt cone 94 is connected to the bottom end of the bearing cavity sleeve 93 to facilitate the installation of the assembled bearing component 9 at the specified position inside the reinforcement frame 5 according to the spacing, and to form an integral structure with the reinforcement frame 5. After the bearing component 9 and the reinforcement frame 5 are installed, concrete is poured into the block mold again to make the concrete completely wrap the reinforcement frame 5 and the bearing component 9, so that the top of the reinforcement head 91 and the bottom of the reinforcement bolt cone 94 can be fully embedded in the concrete to enhance the interaction and integrity with the concrete. After the concrete solidifies, the block body 1 forms an integral structure with the internal reinforcement frame 5 and the bearing component 9.

[0027] In the present invention, according to Figure 1 and Figure 5 As shown, a prefabricated reinforcement component 7 is installed inside the bottom end of the block body 1, and a reinforcing anchor bolt 10 is inserted and installed inside the bottom end of the block body 1. The prefabricated reinforcement component 7 is spliced ​​with the block body 1 through the reinforcing anchor bolt 10, and the splicing seam produced by the splicing is poured with bonding slurry.

[0028] The prefabricated reinforcement assembly 7 includes a bottom bearing frame block 71 , a high-strength metal block 72 is integrally formed on the top of the bottom bearing frame block 71 by casting, and a side bearing frame block 73 is integrally formed inside the top end of the bottom bearing frame block 71 by casting.

[0029] An adhesive block 74 is integrally formed on the top of the side bearing frame block 73 , and the adhesive block 74 is used to form an integrated arrangement with the interior of the block body 1 through the connecting mortar.

[0030] In a specific scheme, a hole for installing a reinforcing anchor 10 is pre-opened at the bottom end of the block body 1 according to the designed position, the reinforcing anchor 10 is inserted into the hole and preliminarily fixed to ensure that its position is accurate and perpendicular to the bottom surface of the block, the prefabricated prefabricated reinforcement component 7 is aligned with the bottom end of the block body 1, and the reinforcing anchor 10 passes through the corresponding reserved hole on the prefabricated reinforcement component 7, and then the prefabricated reinforcement component 7 is placed on the bottom end of the block body 1, and the position is adjusted so that the two fit tightly, and then the pre-prepared bonding slurry is slowly poured into the joint to ensure that the bonding slurry is fully in contact with the bonding block 74 of the prefabricated reinforcement component 7 and the inside of the block body 1 and forms a good bond. After the pouring of the bonding slurry is completed, the prefabricated reinforcement component 7 and the block body 1 form an integral structure.

[0031] In the present invention, according to Figure 1 and Figure 2 As shown, a butt joint groove 2 is provided on the top surface of the block body 1, and the butt joint groove 2 is provided by a manufacturing mold before manufacturing.

[0032] The butt joint groove 2 is used to form a butt joint with the bottom butt joint protrusion of another group of building block bodies 1, so as to strengthen the overall stable connection during construction.

[0033] In a specific solution, at the construction site, the block body 1 with the docking groove 2 is moved to a predetermined position, and then the bottom docking protrusions of another group of block bodies 1 are aligned with the docking grooves 2 of the positioned blocks, so that the docking protrusions are completely embedded in the docking grooves 2. After the docking is completed, further treatment can be performed on the docking position according to the construction requirements, such as applying adhesive or pouring grouting material, etc., to enhance the connection strength of the docking position.

[0034] The wiring diagram of the repair agent capsule 82 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to actual use, so the control method and wiring arrangement of the repair agent capsule 82 will not be explained in detail.

[0035] The method of using the device and the working principle are as follows: first, a concrete main body layer 12 is poured in a mold. When the concrete main body layer 12 is in a plastic state that has not been completely solidified, an aerated concrete layer 13 is poured immediately, so that it is evenly spread on the concrete main body layer 12 and gradually expands and emits gas to form an aerated concrete layer 13 with a porous structure, so that the aerated concrete layer 13 can be tightly combined with the lower concrete main body layer 12 to form an integrated structure, and when the aerated concrete layer 13 is not completely solidified and is in a plastic state, rubber particles are evenly added to its bottom to form a wear-resistant buffer layer 14, and the rubber particles are used to enhance the wear resistance and buffering performance of the bottom of the block, thereby reducing damage caused by friction and collision during use. Then, when the concrete main body 12 is in a plastic state that has not been completely solidified, rubber particles are evenly added to its bottom to form a wear-resistant buffer layer 14. The rubber particles are used to enhance the wear resistance and buffering performance of the bottom of the block, thereby reducing damage caused by friction and collision during use. After the layer 12 and the aerated concrete layer 13 are initially solidified, a polymer modified cement mortar layer 11 is applied to the top surface of the concrete main body layer 12 to form a high toughness and high strength protective layer, and then pre-made corner protection plates 6 are placed at the four end corners of the block body 1, and the side protection components 8 are installed inside the corner protection plates 6, and the right-angle reinforcement anchor bolts 81 pass through the reserved holes on the corner protection plates 6 so that their right-angle intersections are located at appropriate positions at the corners, and then repair agent capsules 82 are sleeved on the left and right ends thereof, and the buffer elastic rod 85 is fastened to the right-angle intersection of the right-angle reinforcement anchor bolts 81, and multiple groups of stress-bearing arc plates 86 are installed on the outside of the buffer elastic rod 85, so that the front end group of stress-bearing arc plates 86 are embedded in the outer corners of the corner protection plates 6, and the middle one The stress-bearing arc plate 86 is in contact with the outer wall surface of the repair agent capsule 82. Finally, by pouring concrete in the corner protection plate 6, the side protection assembly 8 and the corner protection plate 6 are formed into a whole, so that the entire corner protection structure is fastened to the block body 1. During use, the polymer modified cement mortar layer 11 is used to resist external erosion and slight collisions, protect the internal concrete main layer 12 and the aerated concrete layer 13, and reduce the friction damage with the ground or other supporting structures through the wear-resistant buffer layer 14. When the corners of the block body 1 are hit by a large external force or damaged by other reasons, the external force first acts on the corner protection plate 6, and the corner protection plate 6 transmits part of the impact force to the buffer elastic rod 85, so that the buffer elastic rod 85 is compressed and absorbs A part of the energy is absorbed by the block body 1 to reduce the direct impact on the block body 1. When the impact force is too large, the arc plate 86 causes the repair agent capsule 82 to rupture, and the repair agent flows out and fills along the repair path cavity 83 and the corner repair path cavity 84, so that it is easy to solidify in the air or after reacting with the block material, thereby realizing self-repair and restoring the partial strength and integrity of the corners. Then, during the pouring process, the concrete is evenly distributed in the mold, and then the block mold containing the concrete and the opening mold is placed in an autoclave for autoclaving. Under high temperature and high pressure, a series of physical and chemical reactions occur inside the concrete, generating gas and forming pores, so that these pores are gradually arranged along the direction set by the mold specifically for forming the opening during the formation process.Finally, the first anti-stress ventilation hole 3 and the second anti-stress ventilation hole 4 of the honeycomb structure are formed. After the autoclaving is completed, the reinforcement frame 5 is prepared according to the size of the block, and then it is placed in the middle position of the mold of the block body 1 and initially fixed to ensure that its position is accurate and will not be displaced during the subsequent pouring process. The setting of the bearing assembly 9 makes the reinforcement head 91 and the bearing cavity sleeve 93 tightly connected to ensure a firm connection and good sealing to prevent the leakage of the internally filled helium. Then the bearing support plate 92 is installed on both ends of the side of the bearing cavity sleeve 93 to also ensure the stability of the connection. Finally, the reinforcement bolt cone 94 is connected to the bottom end of the bearing cavity sleeve 93, so that the assembled bearing assembly 9 is installed at the specified position inside the reinforcement frame 5 according to the spacing, and it forms an integral structure with the reinforcement frame 5. After the bearing assembly 9 and the reinforcement frame 5 are installed, concrete is poured into the block mold again, so that the concrete completely wraps the reinforcement frame 5 and the bearing assembly 9, so that the top of the reinforcement head 91 and the bottom of the reinforcement bolt cone 94 can be fully embedded in the concrete to enhance the interaction and integrity with the concrete. After the concrete solidifies, the block body 1 and the internal reinforcement frame 5 and the bearing The load-bearing assembly 9 forms an integral structure. Secondly, a hole for installing the reinforcing anchor bolt 10 is pre-opened at the bottom end of the block body 1 according to the designed position, and the reinforcing anchor bolt 10 is inserted into the hole and initially fixed to ensure that its position is accurate and perpendicular to the bottom surface of the block. The prefabricated prefabricated reinforcement assembly 7 is aligned with the bottom end of the block body 1, and the reinforcing anchor bolt 10 passes through the corresponding reserved hole on the prefabricated reinforcement assembly 7. Then, the prefabricated reinforcement assembly 7 is placed at the bottom end of the block body 1, and the position is adjusted so that the two fit closely. Then, the pre-prepared bonding slurry is slowly poured into the joint to ensure that the bonding slurry is bonded to the prefabricated The bonding block 74 of the reinforcement component 7 and the interior of the block body 1 are fully in contact and form a good bond. After the bonding slurry is poured, the prefabricated reinforcement component 7 and the block body 1 form an integral structure. Then, at the construction site, the block body 1 with the docking groove 2 is moved to a predetermined position, and then the bottom docking protrusions of another group of block bodies 1 are aligned with the docking groove 2 of the positioned block, so that the docking protrusions are completely embedded in the docking groove 2. After the docking is completed, further treatment can be performed on the docking part according to the construction requirements, such as applying adhesive or pouring grouting materials, etc., to enhance the connection strength of the docking part.
