[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] like Figure 1-Figure 7 As shown, the present disclosure provides a hollow wall structure, including exterior wall bricks 1 constituting an exterior wall, interior wall bricks 2 constituting an interior wall, and overlapping bricks 3 connecting the exterior wall bricks 1 and the interior wall bricks 2, wherein an air barrier is formed between the exterior wall bricks 1 and the interior wall bricks 2, and further comprising a flexible reinforcement net 4, wherein the flexible reinforcement net 4 is attached to the inner surfaces of the exterior wall bricks 1 and the interior wall bricks 2 facing the air barrier, and a reserved hole 401 is opened on the flexible reinforcement net 4 for laying the overlapping bricks 3.

[0034] Specifically, the first end of the overlapping brick 3 is laid between two exterior wall bricks 1 spaced apart along the extension direction of the wall (i.e., the direction of the wall on the horizontal plane); the end face of the first end of the overlapping brick 3 and the outer surface of the exterior wall brick 1 facing away from the air barrier together constitute the outer surface of the wall; the second end of the overlapping brick 3 is laid between two interior wall bricks 2 spaced apart along the extension direction of the wall; the end face of the second end of the overlapping brick 3 and the outer surface of the interior wall brick 2 facing away from the air barrier together constitute the inner surface of the wall; the air barrier formed between the exterior wall bricks 1 and the interior wall bricks 2 enables the hollow wall to have a good thermal insulation effect; the overlapping bricks 3 connect the exterior of the wall with the interior of the wall as a whole.

[0035] like Figure 1As shown, the overlap bricks 3 connect the external wall and the internal wall as a whole, and they are also distributed in the air barrier. Therefore, it is difficult to fully lay the reinforcement parts on the inner surface of the external wall bricks 1 and the inner wall bricks 2 by conventional construction methods. The present disclosure is based on the construction method of laying masonry structures layer by layer, and uses a flexible reinforcement net 4 to fix it on the inner surface of the external wall bricks 1 and the inner wall bricks 2 by laying them layer by layer following the masonry height. Among them, when the wall structure is constructed in a single layer, the external wall bricks 1 and the inner wall bricks 2 are first laid, and then the flexible reinforcement net 4 is attached and fixed to the inner surface of the external wall bricks 1 and the inner wall bricks 2, and finally the overlap bricks 3 are laid between the external wall bricks 1 and the inner wall bricks 2 through the reserved holes 401, and the above steps are repeated to complete the single-layer construction. Among them, the position of the reserved hole 401 on the flexible reinforcement net 4 is configured according to the position of the overlapping bricks 3 in the wall structure, so that the flexible reinforcement net 4 can gradually unfold with the masonry height and finally be fully spread on the inner surface of the exterior wall bricks 1 and the interior wall bricks 2, effectively improving the integrity of the structure.

[0036] like Figure 2 As shown, in some embodiments, for the convenience of construction, the unpaved part of the flexible reinforcement net 4 can be rolled up and placed, and when paving, the flexible reinforcement net 4 can be partially unfolded and fixed, and the above construction process is repeated to build and lay the flexible reinforcement net 4 layer by layer to complete the masonry construction of the entire wall structure. The reinforcement effect of the flexible reinforcement net 4 improves the integrity of the wall structure, and on the premise of ensuring the volume of the cavity of the hollow wall structure, the structural integrity is effectively enhanced and the earthquake resistance is improved. Among them, the flexible reinforcement net 4 can be made of polyester fiber mesh or galvanized steel wire mesh. In order to ensure the structural strength, galvanized steel wire mesh is preferably used.

[0037] In addition, the outer wall bricks 1, the inner wall bricks 2 and the overlapping bricks 3 constituting the wall structure can be ordinary fired bricks. In other embodiments, concrete blocks, aerated concrete blocks or composite material blocks can also be selected according to construction requirements.

[0038] In some embodiments, the blocks are connected with mortar, and the thickness of the mortar is between 8 mm and 15 mm, preferably 10 mm.

[0039] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the overlapping bricks 3 are staggered layer by layer along the height direction of the wall.

[0040] Specifically, during the construction of the masonry structure, the overlapping bricks 3 should be arranged alternately in two adjacent layers of bricks in the height direction to avoid forming continuous mortar joints in the wall in the height direction, thereby effectively improving the structural strength.

[0041] like Figure 1As shown, in some embodiments, the overlapping bricks 3 are arranged in a plum blossom pattern and staggered regularly along the height direction. The plum blossom pattern can effectively reduce the amount of overlapping bricks 3 used, and effectively increase the volume of the cavity while ensuring the structural strength. At the same time, the regular distribution of the overlapping bricks 3 makes the reserved holes 401 on the flexible reinforcement net 4 also regularly distributed, which facilitates the large-scale production of the flexible reinforcement net 4 and improves the compatibility between materials.

[0042] like Figure 3 and Figure 7 As shown, in some embodiments, the hollow wall structure further includes ring beams 5 located at the bottom and top of the wall, and the flexible reinforcement net 4 is provided with first anchoring portions 402 for anchoring into the ring beams 5 at both ends in the height direction.

[0043] Specifically, the ring beam 5 can effectively improve the structural integrity of the hollow wall. At the same time, before pouring the ring beam 5 at the bottom of the wall, the first anchoring portion 402 at the first end of the flexible reinforcement net 4 is placed at a designated position in the template of the ring beam 5 at the bottom, and the pouring is completed to form a pre-embedded part. After the ring beam 5 at the bottom has a certain strength, the wall is built on the ring beam 5, and the flexible reinforcement net 4 is laid on the surface of the brick layer by layer as the wall is built and fixed. When the wall is built, the first anchoring portion 402 at the second end of the flexible reinforcement net 4 is extended upward from the wall, placed in the template of the ring beam 5 at the top, and then poured to form a pre-embedded part. By arranging the first anchoring portion 402 that can be anchored in the ring beam 5 on the flexible reinforcement net 4, it is possible to effectively avoid the flexible reinforcement net 4 from falling off the brick surface, and further improve the structural stability. Among them, the flexible reinforcement nets 4 in the adjacent two layers of masonry structure can be pre-embedded in the ring beam 5 at the same time.

[0044] In some embodiments, since the ring beam 5 and the bricks are bonded by mortar, the surface of the ring beam 5 contacting the bricks can be roughened to strengthen the bonding force between the surface and the mortar.

[0045] like Figure 3 As shown, in some embodiments, the hollow wall structure further includes structural columns 6 arranged at intervals along the extension direction of the wall, and second anchoring portions 403 for anchoring the structural columns 6 are provided at both ends of the flexible reinforcement net 4 along the extension direction of the wall.

[0046] Specifically, the structural column 6 can further improve the integrity of the structure. Similarly, before pouring the structural column 6, the second anchoring portion 403 of the flexible reinforcement net 4 at one end of the structural column 6 is placed in the template of the structural column 6, and is pre-embedded after pouring. The structural column 6 can also pre-embed the flexible reinforcement net 4 in the masonry structure on both sides thereof along the extension direction of the wall.

[0047] In some embodiments, in order to save construction costs, structural columns 6 are provided in the middle of the wall only when the wall height is greater than 5 m or when the wall length along the extension direction is greater than 8 m.

[0048] like Figure 3 As shown, in some embodiments, since the overlapping bricks 3 are arranged in a plum blossom shape, at the edge of the wall extension direction, the concave and convex cooperation between the exterior wall bricks 1, the interior wall bricks 2 and the overlapping bricks 3 forms a structure similar to a horse tooth joint, which can effectively enhance the bonding strength between the wall and the structural column 6.

[0049] In actual construction, in order to avoid the overflow of concrete into the air barrier when pouring the ring beam 5 or the structural column 6, which will increase the amount of concrete and increase the construction cost, after the anchoring part of the flexible reinforcement net 4 is thrown out to the embedded position, the edge of the wall can be sealed with blocks of suitable size.

[0050] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the flexible reinforcement mesh 4 includes a plurality of flexible reinforcement meshes 404 , and the plurality of flexible reinforcement meshes 404 can be laid continuously along the extension direction of the wall to fully cover the inner surfaces of the exterior wall tiles 1 and the interior wall tiles 2 .

[0051] Specifically, in order to facilitate the construction workers to lay and fix the flexible reinforcement net 4, the flexible reinforcement net 4 is evenly divided into multiple flexible reinforcement mesh pieces 404 along the extension direction of the wall. The width of each flexible reinforcement mesh piece 404 can be controlled within 60cm-80cm according to the wall structure. Multiple flexible reinforcement mesh pieces 404 are spliced ​​along the extension direction of the wall to form an integral flexible reinforcement net 4.

[0052] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the overlapping bricks 3 are arranged in a plum blossom shape, and the flexible reinforcement mesh 404 can be divided into a first flexible reinforcement mesh 4041 and a second flexible reinforcement mesh 4042, wherein the first flexible reinforcement mesh 4041 becomes the second flexible reinforcement mesh 4042 after being flipped, and the first flexible reinforcement mesh 4041 and the second flexible reinforcement mesh 4042 are alternately arranged along the extension direction of the wall to fully cover the inner surface of the exterior wall tiles 1 and the interior wall tiles 2. Therefore, when the exterior wall tiles 1, interior wall tiles 2 and lap bricks 3 are all made of conventional sintered bricks and the lap bricks 3 are arranged in a plum blossom arrangement, it is only necessary to produce a first flexible reinforcing mesh 4041 with a certain width, cut the first flexible reinforcing mesh 4041 along its length according to the actual wall height on site, and then flip it over to become a second flexible reinforcing mesh 4042. The two can be alternately laid in the wall to meet construction requirements, effectively improving the adaptability of the various materials that make up the hollow wall structure and greatly reducing the material manufacturing cost and construction cost.

[0053] like Figure 4 As shown, in some embodiments, a connecting portion 405 is provided on the flexible reinforcing mesh 404 , and the connecting portion 405 is used to connect two adjacent flexible reinforcing meshes 404 .

[0054] Specifically, the connection part 405 is disposed at the connection position of two adjacent flexible reinforcement meshes 404 , and the connection parts 405 can be fixed by bonding or binding to strengthen the connection between the flexible reinforcement meshes 404 and improve the overall stability of the structure.

[0055] In some embodiments, the flexible reinforcement mesh 4 is fixed to the inner surfaces of the exterior wall tiles 1 and the interior wall tiles 2 by an interface agent.

[0056] Specifically, before using the interface agent for fixing, the oil stains and loose particles on the inner surface of the exterior wall tiles 1 and the interior wall tiles 2 should be removed, and the surface should be made smooth. During the construction process, a brush, roller or spraying equipment can be used to evenly apply the interface agent on the inner surface, and then the flexible reinforcement mesh 4 is laid on the interface agent for fixing. The interface agent here can be an epoxy resin interface agent or a rubber latex interface agent with good bonding strength and durability. In other embodiments, a layer of mortar can also be applied to the surface of the flexible reinforcement mesh 4 after paving to ensure enhanced bonding strength.

[0057] like Figure 3 As shown, in some embodiments, the length of the first anchoring portion 402 along the height direction is 100 mm-150 mm.

[0058] Specifically, in order to ensure that the ring beam 5 can provide sufficient anchoring effect for the flexible reinforcement net 4, while facilitating anchoring construction, reducing unnecessary waste of materials, and ensuring the economy of the structure, the length of the first anchoring portion 402 along the height direction is limited to 100mm-150mm, preferably 120mm.

[0059] like Figure 1 As shown, in some embodiments, the hollow wall structure further includes a heat-insulating material 7 filled in the air barrier.

[0060] Specifically, the heat-insulating material 7 is arranged in the air barrier layer to further enhance the heat-insulating effect of the hollow wall structure, and the heat-insulating material 7 filled in the wall can improve the integrity of the wall. The heat-insulating material 7 can be a foam heat-insulating material with initial fluidity, such as foam rubber or bubble concrete. After the wall is built, the ring beam 5 at the top is not cast. The heat-insulating material 7 is cast from the top into the air barrier layer of the wall. Based on its initial fluidity, the heat-insulating material 7 can fill the air barrier layer of the wall. After solidification, it can not only improve the heat-insulating effect of the wall, but also support the wall, and can squeeze the flexible reinforcement net 4 on the inner surface of the outer wall brick 1 and the inner wall brick 2 to prevent it from falling off.

[0061] The present disclosure also provides a construction method for the above-mentioned hollow wall structure, including the following construction process: S1, positioning and laying exterior wall bricks 1 and interior wall bricks 2; S2, laying and fixing the flexible reinforcement net 4 on the inner surfaces of the exterior wall bricks 1 and the interior wall bricks 2; S3, laying the overlapping bricks 3 between the exterior wall bricks 1 and the interior wall bricks 2 through the reserved holes 401 to complete the overlapping; repeating the above process to complete the construction of the wall.

[0062] Specifically, based on the characteristic that masonry structures are usually built layer by layer, when laying a single layer of bricks, firstly, the exterior wall bricks 1 and interior wall bricks 2 are positioned and laid, then two flexible reinforcement meshes 4 are laid and fixed on the inner surfaces of the exterior wall bricks 1 and the interior wall bricks 2, respectively, and then the overlap bricks 3 are laid between the exterior wall bricks 1 and the interior wall bricks 2 through the reserved holes 401 to complete the laying of one layer of bricks. Repeat the above steps to complete the wall construction.

[0063] In some embodiments, when laying a layer of bricks, first position and lay the first exterior wall brick 1 and the corresponding first interior wall brick 2, then lay and fix two flexible reinforcement nets 4 on the inner surfaces of the first exterior wall brick 1 and the first interior wall brick 2, respectively, and then lay the first lap brick 3 through the reserved hole 401 to form a basic masonry unit 8. Repeat the construction according to the above steps, and sequentially construct multiple basic masonry units 8 in the extension direction of the wall to complete the masonry of a single layer of bricks. Through the above-mentioned masonry method, the exterior wall bricks 1 and the interior wall bricks 2 are alternately laid with the lap bricks 3 in the extension direction of the wall. During the operation, the bonding mortar between the bricks can be squeezed in one direction, which can effectively ensure the construction stability and reduce the influence of the masonry level of the construction personnel on the structural strength.

[0064] Taking the example that the outer wall bricks 1, the inner wall bricks 2 and the overlap bricks 3 are all ordinary fired bricks and the overlap bricks 3 are arranged in a plum blossom pattern in the wall, this construction method is described. The specific construction process is as follows:

[0065] In the first step, the flexible reinforcement net 4 uses a first flexible reinforcement mesh 4041 with a fixed width, cuts it along the length direction according to the wall height, and reserves a first anchoring portion 402 with a length of 120 mm at both ends of the length direction, and flips part of the first flexible reinforcement mesh 4041 to obtain a second flexible reinforcement mesh 4042.

[0066] In the second step, before pouring the ring beam 5 at the bottom of the wall, the first flexible reinforcement mesh 4041 and the second flexible reinforcement mesh 4042 are alternately placed at designated positions along the extension direction of the wall, and their respective first anchoring parts 402 are pre-embedded in the formwork before pouring the ring beam 5, and the remaining parts are curled and placed on the upper side of the ring beam 5 to avoid damage during construction.

[0067] The third step is to cast the ring beam 5 at the bottom of the wall to complete the anchoring.

[0068] The fourth step is to lay the first layer of bricks for the wall. First, lay an exterior wall brick 1 and a corresponding interior wall brick 2. Apply epoxy resin interface agent on the inner surface of the exterior wall brick 1 and the interior wall brick 2, and partially unfold and lay the pre-buried first flexible reinforcement mesh 4041 or second flexible reinforcement mesh 4042 and fix it on the inner surface of the brick. Then, lay the lap brick 3 on one side of the exterior wall brick 1 and the interior wall brick 2 through the reserved hole 401 to complete a basic masonry unit 8. Repeat the construction of multiple basic masonry units 8 in the extension direction of the wall to complete the masonry of the first layer of bricks, wherein the adjacent first flexible reinforcement mesh 4041 and second flexible reinforcement mesh 4042 are fixed to each other through the connection part 405.

[0069] Step 5: Repeat step 4 to build the wall layer by layer. During the building process, the first flexible reinforcement mesh 4041 and the second flexible reinforcement mesh 4042 are unfolded and fixed layer by layer. When building the top layer of bricks, a pouring hole is reserved, and the bubble concrete is poured into the air barrier along the pouring hole. The filling state of the foamed concrete at each position can be determined by knocking the wall surface with a hollow hammer. After confirming that the filling is completed, the pouring hole is closed to complete the wall building.

[0070] In the sixth step, the first anchoring portion 402 located at the other end of the first flexible reinforcing mesh 4041 and the second flexible reinforcing mesh 4042 is thrown upward and embedded in the template before the casting of the ring beam 5 of the upper structure for anchoring.

[0071] Repeat the above steps to complete the construction of the multi-layer hollow wall structure.
