Description

Technical Field

[0001] This application relates to the technical field of masonry structures in building engineering, and in particular to crack-resistant composite infill walls. Background Technology

[0002] Infill walls are walls in frame structures that serve as enclosures and partitions. Their weight is borne by beams and columns, and infill walls are not load-bearing. Existing infill walls are made of bricks, and there are many types of building bricks, including through-hole bricks, blind-hole bricks, solid bricks, hollow bricks, etc.

[0003] In existing technology, infill walls are usually constructed by laying multiple bricks together, with concrete filling the space between adjacent bricks to form a wall. However, in such walls, the bricks are fixed together by concrete, resulting in poor stability. In street-facing buildings, passing vehicles cause ground vibrations, and the walls are subjected to these vibrations over a long period of time. This vibrations can cause adjacent bricks to shift and become misaligned, leading to cracks in the wall surface. Therefore, further improvements are needed. Summary of the Invention

[0004] To improve the crack resistance of walls, this application provides a crack-resistant composite infill wall.

[0005] The crack-resistant composite infill wall provided in this application adopts the following technical solution:

[0006] A crack-resistant composite infill wall includes a main layer, with crack-resistant layers symmetrically arranged on both sides of the main layer, and a plastering layer on the outer side of the crack-resistant layers; the main layer includes multiple modular bricks and multiple butt joints, with the butt joints connecting two adjacent modular bricks, and the two adjacent modular bricks mutually restraining each other through the butt joints; the crack-resistant layers include a protective mesh and a crack-resistant mortar layer filled in the protective mesh, with a connector between the protective mesh and the butt joints, and the protective mesh being installed on the butt joints through the connector.

[0007] By adopting the above technical solution, through the setting of protective netting and connecting strips, adjacent modular bricks are connected and limited by connecting strips, thereby forming a whole between adjacent modular bricks and reducing the possibility of misalignment between adjacent modular bricks; the crack-resistant mortar has a certain toughness and is not easy to crack. The crack-resistant mortar layer is filled with protective netting, which further improves the structural stability of the crack-resistant mortar layer. The protective netting is installed on the connecting strips through connectors, thereby forming a whole between the modular bricks, connecting strips and crack-resistant mortar layer, greatly improving the crack resistance of the overall structure and reducing the possibility of wall cracking.

[0008] Optionally, the two opposite sidewalls of the module brick are respectively provided with a first docking groove and a second docking groove. The docking strip is embedded in the first docking groove, and the docking strip partially protrudes from the first docking groove and is respectively embedded in the second docking groove of two horizontally adjacent module bricks. The two horizontally adjacent module bricks and the two vertically adjacent module bricks are connected by the docking strip.

[0009] By adopting the above technical solution, and by setting multiple modular bricks and multiple connecting strips, the connecting strips connect two horizontally adjacent modular bricks and two vertically adjacent modular bricks to form a whole. This allows two adjacent modular bricks to be mutually restrained by the connecting strips, forming a whole wall structure. This reduces the possibility of misalignment and sliding between two adjacent modular bricks when the ground vibrates, which could lead to wall cracking.

[0010] Optionally, the shapes of the first and second docking grooves are adapted to the shape of the docking strip. The docking strip includes two docking portions with an included angle between them and forming a V-shaped tip. The first docking groove is used for the two docking portions to be matched and embedded. The two docking portions are respectively embedded in the second docking grooves of two horizontally adjacent module bricks.

[0011] By adopting the above technical solution, through the setting of the docking part and the V-shaped tip, two horizontally adjacent module bricks are connected to each other by the docking strip. The V-shaped docking strip can limit the two horizontally adjacent module bricks, reducing the possibility of the two horizontally adjacent module bricks moving away from each other. Two vertically adjacent module bricks are connected by the docking strip, thereby assembling multiple module bricks into a whole and improving the connection stability between module bricks.

[0012] Optionally, the connecting strip has a connecting rod located inside the V-shaped tip. The end of the connecting rod away from the V-shaped tip passes through the module brick and is connected to a locking nut. The locking nut is sleeved on the connecting rod and threadedly connected to the connecting rod.

[0013] By adopting the above technical solution, through the setting of connecting rod and locking nut, when the locking nut is tightened, the connecting rod has a tensile force on the mating strip, and there is an included angle between the two mating parts, so that the two mating parts can push the two horizontally adjacent module bricks respectively, forcing the two horizontally adjacent module bricks to move closer to each other and firmly abut together, thereby improving the connection stability of the overall structure.

[0014] Optionally, the V-shaped tips of two vertically adjacent mating strips are arranged in opposite directions.

[0015] By adopting the above technical solution, the V-shaped tips of two vertically adjacent mating strips are set in opposite directions, so that the connecting rods of the two vertically adjacent mating strips are set in opposite directions. After the two vertically adjacent connecting rods are locked by their respective corresponding locking nuts, the tension of the connecting rods on the module bricks can be balanced, thereby achieving a balance of forces on both sides of the main body layer and improving the connection firmness between the two adjacent module bricks.

[0016] Optionally, a connecting hole is provided on the outer peripheral wall of the end of the connecting rod away from the docking strip, and the connecting member includes a connecting steel wire, which passes through the connecting hole and is tied and fixed to the protective net.

[0017] By adopting the above technical solution, the connection holes provide a channel for the connecting steel bars to pass through, so that the protective net can be tied to the connecting rod by the connecting steel wire, thereby forming an integral whole between the protective net and the main layer.

[0018] Optionally, the end face of the locking nut is provided with a through hole for the connecting steel wire to pass through. When the locking nut is locked to the connecting rod, the end face of the locking nut near the module brick and the side wall of the module brick near the locking nut together abut against the two ends of the connecting steel wire.

[0019] By adopting the above technical solution, and through the setting of the through holes, when binding the connecting steel wire, the connecting steel wire is passed through the through holes, and then the two ends of the connecting steel wire are wrapped around the protective net. Next, the two ends of the connecting steel wire are passed through the through holes, and then the locking nut is tightened, so that the locking nut presses the two ends of the connecting steel wire against the side wall of the module brick, thereby concealing the two ends of the connecting steel wire and reducing the possibility of the two ends of the connecting steel wire being exposed. At the same time, the locking nut presses the two ends of the connecting steel wire against the side wall of the module brick, improving the binding effect of the connecting steel wire, and thus improving the fixing effect of the protective net.

[0020] Optionally, the side wall of the locking nut is provided with a sliding groove communicating with the through hole, and the sliding groove is slidably installed with an anti-detachment component for abutting against the connecting steel wire.

[0021] By adopting the above technical solution, and by setting the anti-detachment component, after the connecting steel wire is inserted through the insertion hole, the anti-detachment component is pressed against the connecting steel wire, reducing the possibility that the two ends of the connecting steel wire will detach from the insertion hole when the locking nut is rotated.

[0022] Optionally, the protective net includes multiple protective strips, and the end face of the connecting rod away from the connecting strip has a snap-fit ​​groove for snapping the protective strip. A guide block is provided at the opening of the snap-fit ​​groove, and the guide block has a guide surface.

[0023] By adopting the above technical solution, and through the setting of the protective strip, when the protective net is installed, it is pushed towards the main layer. When the protective strip abuts against the guide block at the slot opening, the protective strip forces the side wall of the slot to deform through the guide surface of the guide block, thereby opening the slot so that the protective strip is snapped into the slot, so that the protective net is initially connected and fixed to the main layer, improving the connection stability between the protective net and the main layer.

[0024] Optionally, a connecting groove is provided on one end face of the connecting strip, and a connecting block is fixed on the other end face of the connecting strip. The connecting block is used to connect with the connecting groove of the horizontally adjacent connecting strips, and the two horizontally adjacent connecting strips can be detachably installed through the connecting block.

[0025] By adopting the above technical solution and setting the connecting blocks, two horizontally adjacent connecting strips are connected into a whole through the connecting blocks, which further improves the structural stability of the main layer.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting up protective netting and connecting strips, adjacent modular bricks are connected and limited by connecting strips, thus forming a whole between adjacent modular bricks and reducing the possibility of misalignment between adjacent modular bricks; the crack-resistant mortar has a certain toughness and is not easy to crack. The crack-resistant mortar layer is filled with protective netting, which further improves the structural stability of the crack-resistant mortar layer. The protective netting is installed on the connecting strips through connectors, thus forming a whole between the modular bricks, connecting strips and crack-resistant mortar layer, greatly improving the crack resistance of the overall structure and reducing the possibility of wall cracking;

[0028] 2. By using through holes, when binding the connecting wire, the connecting wire is passed through the holes, and then both ends of the connecting wire are wrapped around the protective net. Next, the two ends of the connecting wire are passed through the through holes, and then the locking nuts are tightened. The locking nuts press the two ends of the connecting wire against the side wall of the modular brick, thereby concealing the two ends of the connecting wire and reducing the possibility of the two ends of the connecting wire being exposed. At the same time, the locking nuts press the two ends of the connecting wire against the side wall of the modular brick, improving the binding effect of the connecting wire and thus improving the fixation effect of the protective net.

[0029] 3. By setting up the anti-detachment component, after the connecting steel wire is passed through the through hole, the anti-detachment component is pressed against the connecting steel wire, reducing the possibility that the two ends of the connecting steel wire will come out of the through hole when the locking nut is turned.

[0040] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0041] Example 1:

[0042] This application discloses a crack-resistant composite infill wall.

[0043] Reference Figure 1 , Figure 2The crack-resistant composite infill wall includes a main layer 1, a crack-resistant layer 2, and a plastering layer 3. In this embodiment, there are two crack-resistant layers 2 and two plastering layers 3. The two crack-resistant layers 2 are symmetrically arranged on the inner and outer sides of the main layer 1. The plastering layers 3 are arranged corresponding to the crack-resistant layers 2. Each plastering layer 3 is arranged on the side of the corresponding crack-resistant layer 2 away from the main layer 1.

[0044] Reference Figure 2 , Figure 3 The main body layer 1 includes multiple modular bricks 11 and multiple connecting strips 12. The multiple modular bricks 11 are stacked to form a wall structure. Horizontally adjacent modular bricks 11 abut against each other to form a row. Two vertically adjacent rows of modular bricks 11 are staggered. Connecting strips 12 are installed between two vertically adjacent rows of modular bricks 11 to connect adjacent modular bricks 11.

[0045] Reference Figure 3 , Figure 4 Each module brick 11 has a first mating groove 111 and a second mating groove 112 on its side wall. The first mating groove 111 and the second mating groove 112 are distributed on two opposite side walls of the module brick 11. The shape of the first mating groove 111 and the shape of the second mating groove 112 are adapted to each other. When two horizontally adjacent module bricks 11 abut against each other, the first mating groove 111 and the second mating groove 112 of the two horizontally adjacent module bricks 11 are interconnected.

[0046] Reference Figure 3 , Figure 4 The connecting strip 12 is embedded in the first connecting groove 111. The connecting strip 12 protrudes partially from the first connecting groove 111 and is respectively embedded in the second connecting groove 112 of two horizontally adjacent module bricks 11. The two horizontally adjacent module bricks 11 and the two vertically adjacent module bricks 11 are connected by the connecting strip 12.

[0047] Reference Figure 4 , Figure 5 The shapes of the first docking groove 111 and the second docking groove 112 are adapted to the shape of the docking strip 12. In this embodiment, the docking strip 12 includes two docking portions 121, both of which are elongated. The length directions of the two docking portions 121 have an included angle to form a V-shaped docking strip 12. The connection between the two docking portions 121 forms a V-shaped tip 122. The first docking groove 111 of the module brick 11 is used for matching and embedding the two docking portions 121 of the docking strip 12. The two docking portions 121 are respectively embedded in the second docking grooves 112 of two horizontally adjacent module bricks 11. The V-shaped docking strip 12 connects the two horizontally adjacent module bricks 11 and the two vertically adjacent module bricks 11 to form a whole.

[0048] Reference Figure 4 , Figure 5 In this embodiment, two clearance notches 113 are provided on the side wall of the modular brick 11 near the second docking groove 112. The two clearance notches 113 are symmetrically distributed on both sides of the second docking groove 112. When two horizontally adjacent modular bricks 11 abut against each other, the two clearance notches 113 of the two horizontally adjacent modular bricks 11 combine to form a clearance groove 114. A connecting rod 4 is fixedly installed on the side wall of the docking strip 12. One end of the connecting rod 4 is fixedly connected to the inside of the V-shaped tip 122 of the docking strip 12, and the other end passes through the clearance groove 114 and out of the modular brick 11. A locking nut 41 is sleeved on the outer peripheral wall of the connecting rod 4. 41 is slidably sleeved on the connecting rod 4 and threadedly connected to the outer peripheral wall of the connecting rod 4 (the thread is not shown on the outer peripheral wall of the connecting rod 4 in the figure); with this design, when the locking nut 41 is tightened, the locking nut 41 abuts against the side wall of the module brick 11. When the locking nut 41 is tightened, there is a tensile force on the connecting rod 4, thereby forcing the mating strip 12 to firmly abut against the side wall of the first mating groove 111 and the side wall of the second mating groove 112. The V-shaped mating strip 12 can force two horizontally adjacent module bricks 11 to have a mutual pushing force, thereby making the two horizontally adjacent module bricks 11 abut against each other and improving the connection stability between the two adjacent module bricks 11.

[0049] Reference Figure 3 In this embodiment, the V-shaped tips 122 of two vertically adjacent mating strips 12 are arranged in opposite directions so that the two vertically adjacent connecting rods 4 pass through the inner and outer sides of the main body layer 1 respectively. With this design, after the two vertically adjacent connecting rods 4 are locked with their respective locking nuts 41, the pushing directions of the two vertically adjacent mating strips 12 on the module brick 11 are opposite, thereby balancing the pushing force on the module brick 11.

[0050] Reference Figure 1 , Figure 2 The crack-resistant layer 2 includes a protective net 21 and a crack-resistant mortar layer 22. The crack-resistant mortar layer 22 is filled into the protective net 21. It should be noted that the crack-resistant mortar layer 22 is a crack-resistant mortar made by mixing crack-resistant agent, cement and sand with water in a certain proportion. The crack-resistant mortar is filled into the protective net 21. After the crack-resistant mortar solidifies, the crack-resistant layer 2 is formed. The plastering layer 3 is set as a lime mortar layer.

[0051] Reference Figure 2 , Figure 6In this embodiment, the protective net 21 is a mesh structure formed by multiple protective strips 211 interlacing horizontally and vertically. A connecting block 45 is rotatably installed on the end face of the connecting rod 4 away from the connecting strip 12. The connecting block 45 is elastically set. The end face of the connecting block 45 away from the connecting rod 4 has a snap-fit ​​groove 43 for snapping the protective strip 211. A guide block 44 is fixedly installed at the opening of the snap-fit ​​groove 43. The guide block 44 has a guide surface. The protective strips 211 of the protective net 21 are snapped into the snap-fit ​​groove 43 of the connecting block 45. With this design, when the protective net 21 is installed, the protective strips 211 are snapped into the snap-fit ​​groove 43, so that the protective net 21 is initially fixed to the main body layer 1.

[0052] Reference Figure 5 , Figure 6 A connecting hole 42 is provided on the outer peripheral wall of the end of the connecting rod 4 away from the docking strip 12. A connector is installed between the protective strip 211 and the connecting hole 42. The protective net 21 is fixedly installed on the docking strip 12 through the connector. The connector is set as a connecting steel wire 5. In this embodiment, the connecting steel wire 5 passes through the connecting hole 42 and is tied and fixed to the protective strip 211. The protective net 21 is tied to the connecting hole 42 of the connecting rod 4 through the connecting steel wire 5, and is engaged with the protective strip 211 in the engagement groove 43, so that the protective net 21 is fixedly installed on the main body layer 1, thereby improving the connection firmness between the main body layer 1 and the crack-resistant layer 2.

[0053] The implementation principle of Embodiment 1 of this application is as follows: two horizontally adjacent modular bricks 11 and two vertically adjacent modular bricks 11 are connected to each other by a butt joint 12. After the butt joint 12 is locked by the connecting rod 4 and the locking nut 41, the adjacent modular bricks 11 are firmly pressed together, which improves the structural strength of the main layer 1 and reduces the possibility of wall cracking when the ground vibrates. The butt joint 12 is V-shaped and the V-shaped tips 122 of the vertical butt joint 12 face opposite directions. On the one hand, the two vertically adjacent butt joint 12 are pulled by their respective corresponding connecting rods 4, and the tension of the two vertically adjacent butt joint 12 is in opposite directions, so that the force on the modular bricks 11 is balanced. On the other hand, the two vertically adjacent rows of butt joint 12 can be used to connect the protective nets 21 on the inner and outer sides of the main layer 1, so that the main layer 1 and the crack-resistant layers 2 on both sides of the main layer 1 form a whole, further improving the crack resistance of the overall structure.

[0054] Example 2:

[0055] This application discloses a crack-resistant composite infill wall.

[0056] Reference Figure 7 The difference between the crack-resistant composite infill wall disclosed in this application and Example 1 is that:

[0057] In this embodiment, a connecting groove 123 is provided on one end face of the connecting strip 12. The connecting groove 123 is a T-shaped groove. A connecting block 124 is fixed on the other end face of the connecting strip. The shape of the connecting block 124 is adapted to the shape of the connecting groove 123. The connecting block 124 is used to match the connecting groove 123 inserted into the horizontally adjacent connecting strip 12. The two horizontally adjacent connecting strips 12 can be detached and installed through the connecting block 124.

[0058] Reference Figure 8 In this embodiment, the locking nut 41 has a through hole 411 on its end face near the connecting block 45. There are two through holes 411 arranged at axial intervals around the connecting rod 4. Each through hole 411 is a through hole that passes through the locking nut 41. The two through holes 411 are used for the two ends of the connecting wire 5 to pass through. When the locking nut 41 is locked to the connecting rod 4, the end face of the locking nut 41 near the module brick 11 and the side wall of the module brick 11 near the locking nut 41 together abut against the two ends of the connecting wire 5.

[0059] The implementation principle of Embodiment 2 of this application is as follows: When binding the connecting wire 5, one end of the connecting wire 5 is passed through the connecting hole 42, and then both ends of the connecting wire 5 are respectively wrapped around the protective strip 211 of the protective net 21. Then, the two ends of the connecting wire 5 are passed through the through hole 411 of the locking nut 41 in sequence. Finally, the locking nut 41 is rotated to force the locking nut 41 to lock the connecting rod 4. When the locking nut 41 moves towards the side of the connecting strip 12, it can press the two ends of the connecting wire 5 against the side wall of the module brick 11 near the locking nut 41, thereby hiding the two ends of the connecting wire 5, reducing the possibility of safety hazards caused by the tips of the two ends of the connecting wire 5 pointing outwards, and improving the connection stability between the protective net 21 and the main body layer 1.

[0060] Example 3:

[0061] This application discloses a crack-resistant composite infill wall.

[0062] Reference Figure 9 The difference between the crack-resistant composite infill wall disclosed in this application and Example 2 is that:

[0063] In this embodiment, the side wall of the locking nut 41 is provided with a sliding groove 412. There are two sliding grooves 412, and the two sliding grooves 412 are provided in a one-to-one correspondence with the two through holes 411. Each sliding groove 412 is connected to the corresponding through hole 411. Each sliding groove 412 is slidably installed with an anti-detachment component 6 for abutting against the connecting steel wire 5.

[0064] Reference Figure 9The anti-detachment component 6 includes a sliding rod 61, a first push bar 62, and a second push bar 63. The sliding rod 61 is slidably installed in the sliding groove 412. One end of the sliding rod 61 passes through the groove of the sliding groove 412 away from the through hole 411 and is fixedly installed in the first push bar 62. The second push bar 63 is located in the through hole 411. The end face of the sliding rod 61 away from the first push bar 62 passes through the through hole 411 and is fixedly installed in the second push bar 63.

[0065] The implementation principle of Embodiment 3 of this application is as follows: After the two ends of the connecting steel wire 5 are respectively inserted into the two through holes 411, the two first push bars 62 are pushed, forcing the two first push bars 62 to move closer to each other, thereby forcing the two second push bars 63 to move closer to each other, so as to press against the two ends of the connecting steel wire 5, thereby pressing the connecting steel wire 5 against the through holes 411; using a wrench to engage the locking nut 41, the wrench can clamp the two first push bars 62 to keep the second push bars 63 pressed against the connecting steel wire 5, and then rotating the wrench will drive the locking nut 41 to rotate towards the side closer to the engaging bar 12. The second push bars 63 can press the connecting steel wire 5 against the through holes 411, reducing the possibility that the two ends of the connecting steel wire 5 will disengage from the through holes 411 when the locking nut 41 is rotated.

[0066] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
