Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building materials, in particular to a combined brick and a preparation method thereof. BACKGROUND

[0002] On the one hand, the proportion of buildings over 100 meters is increasing year by year, and the self-weight of the wall built by traditional solid bricks has become the main load source of structural design. When the building height exceeds 50 meters, the contribution rate of the wall self-weight to the foundation load is more than 35%, so the wall self-weight becomes the main factor limiting the building height. On the other hand, the General Code for Building Energy Efficiency and Renewable Energy Utilization requires that the average design energy consumption level of residential buildings and public buildings should be reduced by 30% and 20% respectively based on the energy-saving design standard implemented in 2016, and wall insulation is an important part of building energy saving. The high thermal conductivity coefficient of traditional solid bricks leads to high wall heat transfer coefficient of the wall built by traditional solid bricks, and heat is easily lost through the wall, so the wall insulation effect is poor, thereby restricting the implementation of building energy-saving standards. Therefore, it is urgent to design a brick with low container weight and low thermal conductivity coefficient to provide an integrated solution for weight reduction of high-rise buildings and wall insulation.

[0003] In the prior art, for example, the Chinese utility model patent with application number 200610135881.3 specifically discloses a foam plastic sandwich brick, and specifically discloses that the foam sandwich is first manufactured into a shape according to the required specific gravity of the plastic foam by extrusion or mold pressing, and a reinforcing rib, a dovetail groove with a rounded corner, a circular or elliptical structure space are reserved for inlaying with the outer shell. The mold for the sandwich brick is manufactured. The concrete material is manufactured. The foam sandwich is placed in the mold on a molding machine or a production line, and then the concrete material is filled. After the concrete is solidified, the hollow mold part is pulled out, and the mold is disassembled. However, the brick manufactured by the manufacturing method of the patent has a square structure, and when the combined brick with a square structure is arranged in a "straight brick" masonry method with the vertical joints of the upper and lower bricks aligned, the upper and lower combined bricks mainly rely on the bonding force of the mortar, lack the mechanical friction force generated by mutual engagement, and are prone to poor integrity and insufficient stability of the wall, thereby causing the risk of shaking or tilting.

The filled thermal insulation and fireproof material makes the two building blocks and the structural connecting pieces form a whole, so that the combined brick of the application is obtained.

DETAILED DESCRIPTION

[0031] The technical solutions and technical effects of the embodiments of the present application are further described in detail below in combination with the drawings of the present application.

[0032] Please also refer to Figures 1 to 6 A preparation method of a combined brick, comprising the following steps: S1, two building blocks 110 are prepared by using an extrusion mold 20; S2, a construction connecting piece 120 is prepared; S3, the two ends of the construction connecting piece 120 are connected with the two building blocks 110 respectively, so as to form a to-be-filled brick; S4, placing the to-be-filled brick on the filling mold 30, and filling the thermal and fireproof material 130 into the filling mold 30; wherein the filling mold 30 comprises a female mold bottom plate 310, a male mold upper plate 320, a left baffle 330 and a right baffle 340, the opposite surfaces of the female mold bottom plate 310 and the male mold upper plate 320 are respectively provided with a first tenon 311 and a first mortise 321, and the first tenon 311 and the first mortise 321 jointly form a mortise and tenon structure; the opposite surfaces of the left baffle 330 and the right baffle 340 are respectively provided with a second tenon 331 and a second mortise 341, and the second tenon 331 and the second mortise 341 jointly form a mortise and tenon structure; the thermal and fireproof material 130 forms a first assembly mortise 132 on the lower surface thereof under the guidance of the first tenon 311, forms a first assembly tenon 131 on the upper surface thereof under the guidance of the first mortise 321, forms a second assembly mortise 134 on the left surface thereof under the guidance of the second tenon 331, and forms a second assembly tenon 133 on the right surface thereof under the guidance of the second mortise 341; S5, taking the filled brick out of the filling mold to obtain the prepared combined brick 10.

[0033] Specifically, the two building blocks 110 shown in FIG. Figure 2 are prepared by using the extrusion mold 20, then the construction connecting piece 20 is prepared, the two ends of the construction connecting piece 20 are respectively inserted into the two building blocks 110, and the to-be-filled brick shown in FIG. Figure 3 is formed, finally, the to-be-filled brick is placed on the filling mold 30 in the manner shown in FIG. Figure 6 , and the thermal and fireproof material 130 is filled into the filling mold 30, wherein the thermal and fireproof material 130 forms the first assembly tenon 131 and the first assembly mortise 132 on the upper and lower surfaces thereof under the guidance of the filling mold 30, and forms the second assembly tenon 133 and the second assembly mortise 134 on the left and right surfaces thereof. Figure 5 Figure 4 The filled thermal and fireproof material 130 makes the two building blocks 110 and the construction connecting piece 120 form an integral whole, thereby obtaining the combined brick 10 of the present application. Since the density of the thermal and fireproof material 130 is low, the weight thereof is lower than that of the ordinary brick, and therefore, compared with the solid brick, the present application can reduce the bulk density of the whole brick by filling the thermal and fireproof material 130 between the two building blocks 110, which is convenient for transportation and construction, and further reduces the self-weight of the building and the construction cost. Meanwhile, the thermal conductivity of the thermal and fireproof material 130 is lower than that of the ordinary brick and the concrete, and when the heat is transferred from one building block to another, the thermal and fireproof material filled between the two building blocks can block the heat transfer and reduce the thermal bridge effect, thereby reducing the thermal conductivity of the whole combined brick and further improving the thermal insulation effect and the energy-saving rate of the building.

[0034] ​Meanwhile, the filling mold 30 of the present application is provided with the first tenon 311 and the first groove 321 on the opposite surfaces of the female mold bottom plate 310 and the male mold upper plate 320 respectively, and the second tenon 331 and the second groove 341 on the opposite surfaces of the left baffle 330 and the right baffle 340 respectively, so that the filled thermal insulation fireproof material 130 forms the first assembly tenon 131 on the upper surface, the first assembly groove 132 on the lower surface, the second assembly tenon 133 on the right surface and the second assembly groove 134 on the left surface, so that the upper surface and the right surface of the combined brick are convex, and the lower surface and the left surface are concave. Therefore, when the combined brick is used for wall building, the first assembly tenon 131 of the lower combined brick can be inserted into the first assembly groove 132 of the upper combined brick for the adjacent combined bricks in the up-down direction, and the second assembly tenon 133 of the left combined brick can be inserted into the second assembly groove 134 of the right combined brick for the adjacent combined bricks in the left-right direction, and then the inserted bricks are bonded by the bonding material, so that the combined bricks form the structure of mutual engagement and close connection, thereby generating the mechanical friction force, improving the integrity and stability of the wall.

[0035] Further, please refer to Figure 7 , Figure 8 and Figure 9 , the extrusion mold 20 includes a mold body 210, a demolding assembly 220, a receiving bottom plate 230 and a through-hole forming column assembly 240. A plurality of extrusion channels 211 are vertically arranged in the mold body 210, and the extrusion channels 211 are matched with the outer contour of the building block 110 of the combined brick 10. The demolding assembly 220 is located above the mold body 210, the receiving bottom plate 230 and the through-hole forming column assembly 240 are both located below the mold body 210, and the receiving bottom plate 230 is located between the mold body 210 and the through-hole forming column assembly 240. A plurality of groups of through holes 231 are arranged on the receiving bottom plate 230, and each group of through holes 231 corresponds to a plurality of extrusion channels 211. The step S1 specifically includes the following steps: S11, the upper part of the through-hole forming column assembly 240 is inserted into the plurality of extrusion channels 211 through the plurality of groups of through holes 231; S12, the forming slurry is injected from above the extrusion channels 211 to form a plurality of building blocks 110 and to be formed. S13, after the plurality of building blocks 110 are formed, the bottom of the demolding assembly 220 is inserted into the extrusion channel 211, and the plurality of building blocks 110 are pressed to move downward, the plurality of building blocks 110 press the receiving bottom plate 230 to move downward, the receiving bottom plate 230 presses the through-hole forming column assembly 240 to move downward and extract the extrusion channel 211, so that the plurality of building blocks 110 are inserted and connected to the through-hole forming column assembly 240 and are placed on the receiving bottom plate 230; S14, the receiving bottom plate 230 is lifted from above the through-hole forming column assembly 240 to drive the plurality of building blocks 110 to be extracted from the through-hole forming column assembly 240, and the unloading of the plurality of building blocks 110 is completed.

[0036] Specifically, the extrusion die 20 of the present application can be used for mass production of building blocks. When the extrusion die 20 is used to prepare building blocks, the upper part of the through-hole forming column assembly 140 is first inserted into a plurality of extrusion channels 211 through a plurality of groups of through holes 231, so that the upper surface of the receiving bottom plate 230, the upper part of the through-hole forming column assembly 240 and the inner wall of the extrusion channel 211 form a plurality of building block 110 forming spaces. Then the forming slurry is injected into the plurality of building block 110 forming spaces from above the extrusion channel 211, and the plurality of building blocks 110 are formed and molded. The forming slurry can be concrete, clay, shale, siliceous material or other raw materials used to make building blocks. After the plurality of building blocks 110 are formed, the plurality of building blocks 110 need to be demolded. During demolding, the operator controls the demolding assembly 220 to move downward, inserts the bottom of the demolding assembly 220 into the extrusion channel 211, that is, inserts the bottom of the demolding assembly 220 into the plurality of building block 110 forming spaces, and presses the plurality of building blocks 110 to move downward for demolding. While the plurality of building blocks 110 move downward, the receiving bottom plate 230 is pressed to move downward, the receiving bottom plate 230 presses the through-hole forming column assembly 240 to move downward and extracts the extrusion channel 211, so that the plurality of building blocks 110 are inserted and connected to the through-hole forming column assembly 240 and are placed on the receiving bottom plate 230. Finally, the operator lifts the receiving bottom plate 230 from above the through-hole forming column assembly 240, at this time, the plurality of building blocks 110 placed on the receiving bottom plate 230 are extracted from the through-hole forming column assembly 240 along with the lifting of the receiving bottom plate 230, thereby completing the unloading of the plurality of building blocks 110. Therefore, the extrusion die 20 provided by the present application not only can form a plurality of building blocks 110, but also can press out and unload a plurality of building blocks 110 which have been formed from their respective forming spaces at one time, thereby reducing the labor intensity of the operator and improving the work efficiency.

[0037] Further, please refer to Figure 1 and Figure 11, the demolding assembly 220 includes a first support plate 221, a plurality of block base samples 222, each of which is fixedly connected vertically to the lower surface of the first support plate 221, and the plurality of block base samples 222 correspond one-to-one to the plurality of extrusion channels 211; in step S13, the bottom of the demolding assembly 220 is inserted into the extrusion channel 211, and the plurality of building blocks 110 are pressed to move downward, specifically including: placing the first support plate 221 above the extrusion channel 211 and pressing downward, the first support plate 221 drives the plurality of block base samples 222 to be inserted into the plurality of extrusion channels 211 respectively, and the plurality of building blocks 110 are pressed to move downward for demolding. Specifically, as shown in Figure 11 , the shapes of the plurality of block base samples 222 match the forming spaces of the plurality of building blocks 110, so the lower surfaces of the block base samples 222 have the same shape as the upper surfaces of the building blocks 110, that is, the block base samples 222 vertically press the building blocks, which actually plays the role of a "male mold", so that the building blocks can move smoothly along the extrusion channel 211 during demolding, greatly reducing the damage, cracking or deformation of the block base corners caused by uneven stress, skew or friction. At the same time, the plurality of block base samples 222 are integrated on the first support plate 221, which can press out the plurality of already formed building blocks from their respective forming spaces at one time, greatly improving the production efficiency, avoiding the tediousness and time-consuming of individual demolding, and the entire demolding action is driven by the single vertical movement of the first support plate 221, which is very easy to realize automatic control, thereby avoiding uneven stress caused by manual intervention.

[0038] Further, please refer to Figure 1 , in order to simultaneously remove the excess slurry remaining in the through hole 113 of the building block 110 during demolding, ensure the integrity of the through hole structure and improve the smoothness of demolding, a plurality of discharge holes 2211 are also provided on the first support plate 221, which correspond to the through holes of the plurality of block base samples 222. The block base sample 222 is inserted into the forming space of the building block 110 to press the building block 110 to move downward for demolding, and the upper part of the through hole forming column assembly 240 penetrates the through hole 113 of the building block 110 to push the excess forming slurry out through the discharge hole 2211.

[0039] Further, please refer to Figure 2 and Figure 8, the relative inner wall of the extrusion channel 211 is respectively vertically provided with a mounting guide protrusion 2111 and a filling guide protrusion 2112, the mounting groove 111 is formed on the inner end face of the building block 110 under the guidance of the mounting guide protrusion 2111, and the slurry filling groove 112 is formed on the outer end face of the building block 110 under the guidance of the filling guide protrusion 2112. The mounting groove 111 of the building block 110 is used to be connected with the construction connecting piece 120, and the slurry filling groove 112 is used to increase the contact area between the building block 110 and the mortar when the mortar is applied on the outer end face of the building block 110, thereby facilitating the bonding of the mortar.

[0040] In some embodiments, the top width of the mounting guide protrusion 2111 is greater than the bottom width, so that the slot width of the mounting groove 111 is less than the groove bottom width. When the construction connecting piece 120 is inserted into the mounting groove 111, the construction connecting piece 120 is blocked by the slot and cannot be taken out or fallen off from the slot, thereby preventing the construction connecting piece 120 from falling off from the slot of the mounting groove 111.

[0041] In some embodiments, the filling guide protrusion 2112 includes a plurality of first guide protrusions 21121 and a plurality of second guide protrusions 21122, the widths of the first guide protrusions 21121 and the second guide protrusions 21122 are different, and the first guide protrusions 21121 and the second guide protrusions 21122 are staggered to form a plurality of slurry filling grooves 112 with different groove widths on the outer end face of the building block 110, so that the irregular contact surface can be formed through the width difference of the plurality of slurry filling grooves 112, the mortar and the outer end face of the building block 110 can produce more complex mechanical engagement effect, and the bonding effect of the mortar is further enhanced.

[0042] Further, please refer to Figure 10The through-hole forming column assembly 240 includes a second support plate 241 and a plurality of groups of through-hole forming columns 242, each of which is fixedly connected to the upper surface of the second support plate 241 vertically, so as to form the through hole 113 on the side surface of the building block through the guidance of the plurality of groups of through-hole forming columns 242. Specifically, the plurality of groups of through-hole forming columns 242 correspond one-to-one to the plurality of groups of through holes 231, and the second support plate 241 drives the plurality of groups of through-hole forming columns 242 to pass through the plurality of groups of through holes 231 and insert into the plurality of extrusion channels 211. When the molding slurry is injected into the extrusion channel 211, the position of the through-hole forming column 242 is used to form the through hole 113 on the side surface of the building block 110. After the building block 110 is formed, the plurality of building blocks 110 are inserted on the through-hole forming column 242 and are pulled out downward, and then the plurality of building blocks 110 are separated from the through-hole forming column 242 by lifting the receiving bottom plate 130. Thus, compared with the existing technology of pulling out the column from the through hole for demolding and unloading, the through-hole forming column 242 of the present application is fixed on the second support plate 241, and the receiving bottom plate 230 is lifted, so that the building block actively separates from the stationary through-hole forming column 242, thereby transferring the stress point of demolding and unloading from the fragile through hole to the bottom of the building block 110 and the receiving bottom plate 230, effectively reducing the risk of damage to the through hole.

[0043] In some embodiments, after the building block 110 is prepared by the extrusion mold 20, a connecting piece 120 is needed to connect two building blocks 110 together to form a to-be-filled brick. The connecting piece 120 of the present application includes a plug-in connector and a fixing piece, which are made of metal or engineering plastic. As an embodiment, a mold corresponding to the structure of the connecting piece 120 can be made according to the structure of the connecting piece 120, and the material is poured into the mold to be integrally formed to obtain the connecting piece 120. As another embodiment, the fixing piece and the two plug-in connectors can be made respectively, and then the two plug-in connectors are welded on the left and right sides of the fixing piece to obtain the complete connecting piece 120.

[0044] Further, please refer to Figure 12 and Figure 13 The filling mold 30 further includes four plug-in rods 350, each of which is fixedly connected to a corner of the female mold bottom plate 310 vertically; and a filling hole 322 is formed on the first groove 321. Step S4 specifically includes the following steps: S41, placing the to-be-filled brick on the female mold bottom plate 310; S42, inserting the left baffle 330 into the two plug-in rods 350 on the left side of the female mold bottom plate 310, and inserting the right baffle 340 into the two plug-in rods 350 on the right side of the female mold bottom plate 310; S43, cover the upper part of the to-be-filled brick with the male mold upper plate 320 through the four insertion rods 350 to seal the middle gap of the to-be-filled brick by the cooperation of the female mold bottom plate 310, the left baffle 330, the right baffle 340 and the male mold upper plate 320; S44, inject the thermal and fireproof material 130 into the middle gap of the to-be-filled brick through the filling hole 322.

[0045] After the preparation of the masonry block 110 and the construction connecting piece 120, the two ends of the construction connecting piece 120 are connected with the two masonry blocks 110 respectively to connect the two masonry blocks 110 together through the construction connecting piece 120 to form the to-be-filled brick for filling. Specifically, the to-be-filled brick is placed on the female mold bottom plate 310; the left baffle 330 is inserted on the two insertion rods 350 on the left side of the female mold bottom plate 310, and the right baffle 340 is inserted on the two insertion rods 350 on the right side of the female mold bottom plate 310; the insertion holes are arranged at the four corners of the male mold upper plate 320, the insertion holes of the male mold upper plate 320 are covered on the upper part of the to-be-filled brick through the four insertion rods 350 to seal the middle gap of the to-be-filled brick by the cooperation of the female mold bottom plate 310, the left baffle 330, the right baffle 340 and the male mold upper plate 320; and the thermal and fireproof material 130 is injected into the middle gap of the to-be-filled brick through the filling hole 322. Thus, the masonry block 110 and the construction connecting piece 120 form an integral whole through the thermal and fireproof material 130, which can increase the strength of the entire combined brick 10. And the concentrated load can be dispersed through the construction connecting piece 120, and the pressure is uniformly transmitted to the masonry block 110, which reduces the pressure peak of the construction connecting piece 120 and the thermal and fireproof material 130, thereby improving the overall load-bearing capacity of the combined brick 10.

[0046] In some embodiments, the thermal and fireproof material 130 of the present application can adopt polystyrene, rock wool and other thermal and fireproof foams. After the thermal and fireproof foam is filled, it will solidify to form a three-dimensional support network, thereby supporting the gap between the two masonry blocks, and further enhancing the stability of the building and reducing the risk of deformation of the building. At the same time, since the thermal conductivity of the foam material is much lower than that of concrete and ordinary bricks, the efficiency of heat transfer through the brick ribs is significantly reduced after filling, reducing the key channel of heat bridge formation, and the foam material can absorb and slowly release energy, reducing the phenomenon of intensified heat bridge effect caused by sudden temperature change. In addition, after filling the thermal and fireproof foam between the two masonry blocks, sound resonance can be reduced, forming a more dense sound insulation layer. The sound is absorbed and reflected by the micro-porous structure of the foam in the process of propagation, thereby effectively reducing the interference of external noise on the indoor environment.

[0047] Further, please refer to Figure 12In order to ensure the uniformity of the shape of the thermal insulation fireproof material 130, eliminate individual differences caused by manual adjustment, the female mold bottom plate 310 is further provided with a first limiting part 312, the first limiting part 312 is matched with the through hole 113 of the building block 110, the first limiting part 312 is located on the upper surface of the female mold bottom plate 310, and the first limiting part 312 is located on both sides of the first tenon 311; step S41 specifically includes: when the to-be-filled brick is placed on the female mold bottom plate 310, the through hole 113 on the building block 110 of the to-be-filled brick is inserted downward on the first limiting part 312, so as to limit the relative movement between the to-be-filled brick and the female mold bottom plate 310 through the first limiting part 312, thereby forcing each combined brick 10 to be fixed on the female mold bottom plate 310 according to the preset position, so that the filled thermal insulation fireproof material always exists in the same preset shape.

[0048] Further, please refer to Figure 13 The male mold upper plate 320 is further provided with a second limiting part 323, the second limiting part 323 is matched with the through hole 113 of the building block 110, the second limiting part 323 is located on the lower surface of the male mold upper plate 320, and the second limiting part 323 is located on both sides of the first recess 321; step S43 specifically includes: when the male mold upper plate 320 is covered above the to-be-filled brick through the four plug-in rods 350, the second limiting part 323 is inserted into the through hole 113 of the building block 110 of the to-be-filled brick, so as to limit the relative movement between the to-be-filled brick and the male mold upper plate 320 through the second limiting part 323. Thus, by inserting the first limiting part 312 into the through hole 113 from the lower side of the building block 110 and inserting the second limiting part 323 into the through hole 113 from the upper side of the building block 110, the combined action of the first limiting part 312 and the second limiting part 323 is used to limit the to-be-filled brick from shaking when filling the thermal insulation fireproof material 130, and the uniformity of the shape of the thermal insulation fireproof material 130 is ensured.

[0049] Further, please refer to Figure 12The left baffle 330 is provided with a left plug-in ring 332, and the right baffle 340 is provided with a right plug-in ring 342. The step S42 specifically comprises: the left plug-in ring 332 on the left baffle 330 is sleeved on the two plug-in rods 350 on the left side of the female mold bottom plate 310, and the right plug-in ring 342 on the right baffle 340 is sleeved on the two plug-in rods 350 on the right side of the female mold bottom plate 310. Specifically, the left plug-in ring 332 is two groups, which are respectively arranged on the two sides of the left baffle 330, and the left plug-in ring 332 is arranged on the side of the left baffle 330 away from the to-be-filled brick, and the left plug-in ring 332 is matched with the two plug-in rods 350 on the left side of the female mold bottom plate 310, and the two groups of left plug-in rings are respectively sleeved on the two plug-in rods 350 on the left side of the female mold bottom plate 310, so as to install the left baffle 330 on the female mold bottom plate 310.

Wherein, the three left plug-in rings 332 are a group, and the three right plug-in rings 342 are a group.

[0050] The application further provides a combined brick 10 prepared by the preparation method of the combined brick. Figures 2 to 5The prepared combined brick 10 comprises two oppositely arranged building blocks 110 and a construction connecting piece 120 arranged between the two building blocks 110. An inner end surface of each of the two building blocks 110 is longitudinally provided with a mounting groove 111, one end of the construction connecting piece 120 is inserted into the mounting groove 111 of one of the building blocks 110, and the other end of the construction connecting piece 120 is inserted into the mounting groove 111 of the other building block 110, so as to connect the two building blocks 110 together; an outer end surface of each of the building blocks 110 is longitudinally provided with a slurry filling groove 112, so as to increase the contact area of the building block 110 with the cement mortar; and a side surface of each of the building blocks 110 is provided with a plurality of through holes 113 arranged at equal intervals, so as to be inserted with a tie steel bar; wherein the through holes 113 are arranged in parallel with the mounting grooves 111 and the slurry filling grooves 112. The two building blocks 110 are filled with a thermal insulation fireproof material 130, and a first assembly tenon 131 is formed on an upper surface of the thermal insulation fireproof material 130, a first assembly groove 132 is formed on a lower surface of the thermal insulation fireproof material 130, the first assembly tenon 131 corresponds to the first assembly groove 132 in structure, a second assembly tenon 133 is formed on a right surface of the thermal insulation fireproof material 130, a second assembly groove 134 is formed on a left surface of the thermal insulation fireproof material 130, and the second assembly tenon 133 corresponds to the second assembly groove 134 in structure, so that the combined brick 10 is inserted and matched with an adjacent combined brick through the first assembly tenon 131, the first assembly groove 132, the second assembly tenon 133 or the second assembly groove 134.

[0051] The combined brick 10 of the present application, because the thermal insulation fireproof material 130 has low density, the weight of the combined brick 10 is lower than that of the common brick, so compared with the solid brick, the present application fills the thermal insulation fireproof material 130 between two building blocks 110, which can reduce the unit weight of the whole brick, facilitate transportation and construction, and further reduce the self-weight of the building and the construction cost. At the same time, the thermal conductivity of the thermal insulation fireproof material 130 is lower than that of the common brick and the concrete, when the heat is transferred from one building block to another, the thermal insulation fireproof material 130 filled between two building blocks 110 can block the heat transfer and reduce the heat bridge effect, thereby reducing the thermal conductivity of the whole combined brick 10, and further improving the thermal insulation effect and energy saving rate of the building. Moreover, when filling the thermal insulation fireproof material 130, the upper surface of the thermal insulation fireproof material 130 is formed with the first assembly tenon 310, the lower surface is formed with the first assembly groove 320, the right surface is formed with the second assembly tenon 330, and the left surface is formed with the second assembly groove 340. When the wall is built between the combined bricks 10, the thermal insulation fireproof material of the lower brick is inserted into the upper brick, and the thermal insulation fireproof material of the left brick is inserted into the right brick, so that there is thermal insulation fireproof material between the brick joints of two adjacent combined bricks. When the two adjacent combined bricks are bonded, mortar is applied to the opposite sides of the building blocks of the two adjacent combined bricks. When the common brick is used to build the wall, the opposite sides of the two adjacent bricks are fully coated with mortar. Therefore, compared with the common brick, the combined brick 10 of the present application can reduce the amount of mortar used when building the wall. Moreover, the thermal conductivity of the mortar is higher than that of the thermal insulation fireproof material 130, the brick joints of the common brick are entirely heat-conducted through the mortar, while the heat transfer path of the brick joints between the two bricks of the present application is "mortar-thermal insulation fireproof material-mortar", when the heat is transferred from the mortar of the brick joint to the thermal insulation fireproof material, the thermal insulation fireproof material blocks the heat transfer, thereby reducing the heat transfer from the brick joint and further blocking the generation of the heat bridge effect, and improving the thermal insulation performance of the combined brick. In addition, the building block 110 and the structural connecting piece 120 form an integral whole through the thermal insulation fireproof material 130, which can increase the strength of the whole combined brick 10. Moreover, the concentrated load can be dispersed through the structural connecting piece 120, and the pressure is uniformly transmitted to the building block 110, thereby reducing the pressure peak of the structural connecting piece 120 and the thermal insulation fireproof material 130, and improving the overall load-bearing capacity of the combined brick 10.

[0052] Meanwhile, the filling mold 30 of the present application is provided with the first tenon 311 and the first groove 321 on the opposite surfaces of the female mold bottom plate 310 and the male mold top plate 320 respectively, and the second tenon 331 and the second groove 341 on the opposite surfaces of the left baffle 330 and the right baffle 340 respectively, so that the filled thermal and fireproof material 130 forms the first assembly tenon 131 on the upper surface, the first assembly groove 132 on the lower surface, the second assembly tenon 133 on the right surface and the second assembly groove 134 on the left surface, so that the upper surface and the right surface of the combined brick 10 are convex, and the lower surface and the left surface are concave. Therefore, when the combined brick 10 is used for wall building, the first assembly tenon 131 of the lower combined brick can be inserted into the first assembly groove 132 of the upper combined brick for the upper and lower adjacent combined bricks, and the second assembly tenon 133 of the left combined brick can be inserted into the second assembly groove 134 of the right combined brick for the left and right adjacent combined bricks, and then the inserted bricks are bonded by the bonding material, so that the combined bricks 10 form the structure of mutual engagement and close connection. The connection between the two combined bricks is partly at the joint of the two building blocks of the bricks, and partly between the two building blocks of the bricks due to the mortise and tenon structure, so that when external force is applied, the pressure is always applied to the building blocks and effectively dispersed by the building blocks, thereby avoiding the direct effect of the pressure on the joint of the tenon and the groove, ensuring the stability of the connection between the two bricks and ensuring the stability and durability of the built wall.
