Description

Technical Field

[0001] This application relates to the field of building wall construction technology, and in particular to a wall structure and its construction process for preventing wall cracking. Background Technology

[0002] Wall cracks are cracks that occur in the wall parts of a building structure. Depending on the material itself, they can be divided into concrete wall cracks, brick masonry wall cracks, new partition wall board cracks, and cracks caused by walls of different materials.

[0003] Cracks in concrete walls are mainly caused by inherent defects in the concrete itself and issues arising during construction. These cracks can be repaired using automated low-pressure grouting. This technology involves injecting a highly fluid resin into the crack. Under gravity, the resin flows into the crack, spreading and filling it, thus achieving the repair. After grouting, the crack is fully filled with resin, resulting in high tensile and adhesive strength, preventing further cracking. However, this method has several drawbacks. First, it requires timely detection of cracks and prompt manual grouting. Cracks in frequently used areas, such as living room and bedroom walls, are easily detected. However, cracks in less frequently used areas, such as storage rooms or unused rooms, may go unnoticed. If cracks are not detected promptly, they can grow larger over time, eventually leading to wall collapse and other dangerous accidents. Second, manual grouting is labor-intensive and costly. Summary of the Invention

[0004] In order to repair wall cracks in a timely manner and prevent the cracks from expanding further, this application provides a wall structure and its construction process for preventing wall cracking.

[0005] This application provides a wall structure for preventing wall cracking, employing the following technical solution: A wall structure for preventing wall cracking includes a wall made of concrete, wherein the concrete contains a certain proportion of capsules, each capsule containing an adhesive for filling cracks. Each capsule contains at least two different adhesives, which are separated by diaphragms. When the wall cracks and causes the capsules to rupture, the different adhesives mix and solidify.

[0006] By adopting the above technical solution, when the wall cracks, the capsule at the crack also ruptures along with the wall. After the capsule ruptures, different types of adhesive flow out from the capsule, and the different adhesives mix in the crack. After the different adhesives mix, they solidify, which plays a role in adhesiveting and filling the crack, preventing the crack from continuing to crack. This process occurs immediately when the crack appears, filling and bonding the crack in time, preventing the crack from continuing to crack and causing safety accidents. Secondly, the whole process occurs automatically without human intervention, saving manpower and material resources and reducing economic costs.

[0007] Optionally, the capsule is elongated and has three septa inside, which divide the capsule into eight chambers. The three septa are perpendicular to each other, and adjacent chambers contain different types of adhesive.

[0008] By adopting the above technical solution, when the capsule breaks from the horizontal plane, the diaphragm in the vertical direction will rupture, causing different glues on both sides of the diaphragm to flow out and mix; when the capsule breaks from the vertical plane, the diaphragm in the horizontal direction will rupture, causing different glues on both sides of the diaphragm to flow out and mix. No matter which side the capsule breaks from, the diaphragm will rupture, and the rupture of the diaphragm will cause different glues on both sides of the diaphragm to flow out and mix, and fill the crack under the action of gravity.

[0009] Optionally, a crack-resistant mesh is laid on the wall surface. The crack-resistant mesh is fixed to the wall by wall nails. Half of the wall nail extends into the wall, and the other half of the wall nail is bent and pressed against the wall surface, clamping the crack-resistant mesh between the wall nail and the wall surface to fix the crack-resistant mesh.

[0010] By adopting the above technical solution, the anti-crack mesh is sandwiched between the wall and the wall nail by bending. Through the clamping action of the wall nail, the anti-crack mesh is fixed to the surface of the wall. The anti-crack mesh has a certain tensile strength, which increases the tensile strength of the wall surface and enhances the wall's ability to resist cracking, thus preventing the wall from cracking.

[0011] Optionally, the wall nails are arranged in multiple rows. In each row, one of the two adjacent wall nails has its outer portion bent upwards, while the other has its outer portion bent downwards to increase the stability of the crack-resistant mesh.

[0012] By adopting the above technical solution, one of two adjacent wall nails clamps the crack-resistant mesh by bending upwards, while the other wall nail clamps it by bending downwards. When the crack-resistant mesh is subjected to a downward force along the wall surface and moves downwards, it is hooked by the bent part of the upward-bent wall nail, preventing it from detaching. Therefore, the bent part of the upward-bent wall nail provides resistance to the crack-resistant mesh, while the downward-bent wall nail does not. Conversely, when the crack-resistant mesh is subjected to an upward force along the wall surface, it is hooked by the bent part of the downward-bent wall nail, preventing it from detaching. Therefore, the bent part of the downward-bent wall nail provides resistance to the crack-resistant mesh, while the upward-bent wall nail does not. By alternating these forces, the crack-resistant mesh can resist external forces both upwards and downwards along the wall surface.

[0013] Optionally, the mesh of the crack-resistant mesh can be triangular to enhance its resistance to deformation.

[0014] By adopting the above technical solution, the mesh adopts a triangular structure. The triangular structure has stable performance. This structure can enhance the anti-deformation ability of the crack-resistant mesh, making it easy to flatly attach the crack-resistant mesh to the surface of the wall. The crack-resistant mesh is not prone to wrinkles. If wrinkles do occur, the wrinkled parts cannot withstand the tension well when the crack-resistant mesh is under tension, thus affecting the performance of the crack-resistant mesh.

[0015] Optionally, the outer side of the crack-resistant mesh is covered with a crack-resistant layer, which is made of cement slurry and fiber mixed in a certain proportion.

[0016] By adopting the above technical solution, the crack-resistant layer is laid on the outside of the crack-resistant mesh. The cement slurry has high hardness after solidification, but the toughness of the cement slurry is insufficient. Fiber has high toughness and tensile strength. By adding fiber to the cement slurry, the toughness and strength of the crack-resistant layer are enhanced. The crack-resistant layer plays a protective role for the protective mesh on the one hand, and increases the wall's ability to resist cracking on the other hand.

[0017] Optionally, the fiber is a metal fiber with a length between 1.5 cm and 4 cm and a diameter between 0.05 mm and 0.2 mm. The outer surface of the metal fiber is provided with anti-slip texture.

[0018] By adopting the above technical solutions, metal fibers possess higher strength and toughness compared to ordinary fibers. The length of the metal fibers is controlled between 1.5 cm and 4 cm. If the metal fibers are too long, they are prone to knotting, which is detrimental to construction. If the metal fibers are too short, the contact area between a single metal fiber and the cement slurry is small, which leads to a decrease in the bonding performance between the metal fibers and the cement slurry, and the performance of the metal fibers cannot be fully utilized. The diameter of the metal fibers is controlled between 0.05 mm and 0.2 mm. If the diameter of the metal fibers is too small, the tensile strength that a single metal fiber can withstand will decrease. If the diameter of the metal fibers is too large, the metal fibers will not be easy to bend, which is detrimental to construction. Setting anti-slip textures on the outer surface of the metal fibers helps to increase the contact area between the metal fibers and the cement slurry, increase the friction between the cement slurry and the metal fibers, and improve the bonding performance between the metal fibers and the cement slurry.

[0019] Optionally, the anti-slip texture is a circular pattern coaxial with the metal fiber, and multiple anti-slip textures are arranged along the axis of the metal fiber. The metal fiber is an alloy of copper and iron.

[0020] By adopting the above technical solution, the frictional force generated between the metal fiber and the cement slurry is often along the axial direction of the metal fiber. The annular pattern hinders the movement of the metal fiber along the axial direction of the metal fiber, thereby improving the bonding performance between the metal fiber and the cement slurry. The alloy of copper and iron has the characteristics of strong corrosion resistance, which is conducive to extending the service life of the wall.

[0021] Optionally, the crack-resistant layer is coated with an elastic surface layer.

[0022] By adopting the above technical solution, when a wall develops minor cracks, it generally does not affect the overall performance of the wall. However, these minor cracks often affect the overall aesthetics of the wall. By applying an elastic surface layer to the outside of the crack-resistant layer, when minor cracks appear in the wall, the elastic surface layer is elastic and will not crack, thus ensuring that the overall appearance of the wall is not affected.

[0023] This application also provides a construction process for preventing wall cracking, which uses the above-mentioned wall structure and involves the following steps: Casting walls: A certain amount of capsules are added to the concrete and then the wall is cast. Crack-resistant mesh construction: After the concrete has hardened, nail wall nails into the wall. When nailing the wall nails into the wall, only drive them in half the length of the wall nail. Lay the crack-resistant mesh, bend the wall nails, and fix the crack-resistant mesh to the wall surface through the wall nails. Crack-resistant layer construction: Fibers are added to cement slurry, and the fiber-containing cement slurry is brushed onto the wall surface to form a crack-resistant layer, ensuring that the cement slurry is fully bonded to the wall nails and crack-resistant mesh.

[0024] In summary, this application includes the following beneficial technical effects: 1. This application involves incorporating capsules into concrete and casting them into walls. When the wall cracks, the capsules at the cracks also rupture along with the wall. After the capsules rupture, different types of adhesives flow out from the capsules and mix in the cracks. The mixture of different adhesives solidifies, which acts as an adhesive and filler for the cracks, preventing them from cracking further. This process occurs immediately when cracks appear, filling and bonding them in a timely manner, preventing further cracking and safety accidents. Furthermore, the entire process is automatic and requires no manual intervention, saving manpower and resources and reducing economic costs. 2. This application lays an anti-crack layer on the outside of the anti-crack net. The anti-crack layer is composed of cement slurry and metal fibers. The cement slurry has high hardness after solidification, but its toughness is insufficient. The fibers have high toughness and tensile strength. By adding fibers to the cement slurry, the toughness and strength of the anti-crack layer are enhanced. The anti-crack layer not only protects the protective net, but also increases the wall's ability to resist cracking. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0028] Example 1 This application discloses a wall structure for preventing wall cracking, referring to... Figure 1 and Figure 2 The wall structure for preventing wall cracking includes a wall 1, which is made of concrete 2. The concrete 2 contains a certain proportion of capsules 3, which are filled with adhesive for filling cracks. The capsules 3 contain two different types of adhesive, which are separated by diaphragms 5. When the wall 1 cracks and causes the capsules 3 to rupture, the two different adhesives mix and solidify. To ensure that the capsules 3 also crack when the wall 1 cracks, it is only necessary to ensure that the strength of the capsules 3 is lower than that of the concrete 2. In this embodiment, the capsules 3 are made of glass, which is not easily deformed. When cracks appear in the wall 1, the glass shell of the capsules 3 is easily broken. In other embodiments, the capsules 3 can also be made of other brittle materials with lower strength than cement, such as ceramics.

[0029] When wall 1 cracks, capsule 3 at the crack also ruptures along with wall 1. After capsule 3 ruptures, two different types of adhesive flow out from capsule 3 and mix in the crack. After mixing, the two different types of adhesive solidify, which acts as an adhesive and filler for the crack, preventing it from cracking further. This process occurs immediately when the crack appears, filling and bonding the crack in time, preventing the crack from continuing to crack and causing safety accidents. Furthermore, the whole process occurs automatically without human intervention, saving manpower and resources and reducing economic costs.

[0030] Reference Figure 2 and Figure 3 The capsule 3 is elongated and has three diaphragms 5 inside, which divide the capsule 3 into eight chambers. The three diaphragms 5 are arranged horizontally, vertically, and along the cross-section of the capsule 3, respectively. The three diaphragms 5 are perpendicular to each other in pairs. Adjacent chambers contain different types of adhesive. Four of the eight chambers contain the same type of adhesive, and the other four chambers contain a different type of adhesive. When the two types of adhesive are not in contact with each other, they are both liquids and have stable chemical properties. When the two types of adhesive are mixed, they undergo a chemical reaction and slowly solidify into a solid to fill and bond the cracks. When capsule 3 breaks from the horizontal plane, the diaphragm 5, which is set in the vertical direction, will break, causing different glues on both sides of the diaphragm 5 to flow out and mix. When capsule 3 breaks from the vertical plane, the diaphragm 5, which is set in the horizontal direction, will break, causing different glues on both sides of the diaphragm 5 to flow out and mix. That is, no matter which side capsule 3 breaks from, the corresponding diaphragm 5 will break, and the breaking of the diaphragm 5 will cause different glues on both sides of the diaphragm 5 to flow out and mix, and fill the crack under the action of gravity.

[0031] Reference Figure 4 and Figure 5 Crack-resistant mesh 6 is laid on the surface of wall 1. Crack-resistant mesh 6 is fixed to wall 1 by wall nails 7. Half of the wall nail 7 extends into the wall 1, and the other half of the wall nail 7 is bent and pressed against the surface of wall 1, so that the crack-resistant mesh 6 is clamped between the wall nail 7 and the surface of wall 1 to fix the crack-resistant mesh 6. After the wall nails 7 are first driven into wall 1, the crack-resistant mesh 6 is laid from top to bottom. When laid from top to bottom, the lower crack-resistant mesh 6 will naturally flatten under the action of gravity, and it is not easy for the crack-resistant mesh 6 to wrinkle. After installation, the wall nails 7 are bent by striking them with a hammer. The bent wall nails clamp the anti-crack mesh 6 between the wall 1 and the wall nails 7. Through the clamping action of the wall nails 7, the anti-crack mesh 6 is fixed to the surface of the wall 1. The anti-crack mesh 6 is made of fine iron wire and has good tensile strength. The anti-crack mesh 6 increases the tensile strength of the surface of the wall 1, thereby enhancing the wall 1's ability to resist cracking. The wall nails 7 are arranged in multiple rows from top to bottom, with the positions of the wall nails 7 in each row staggered. In each row of wall nails 7, one of the two adjacent wall nails 7 clamps the crack-resistant mesh 6 by bending upwards, while the other wall nail 7 clamps the crack-resistant mesh 6 by bending downwards. When the crack-resistant mesh 6 is subjected to a downward force along the wall surface and moves downwards, it is hooked by the bent part of the upwardly bent wall nail 7, preventing it from detaching. Therefore, the upwardly bent wall nail... The bent portion of the wall nail 7 acts as a barrier to the crack-resistant mesh 6, while the downward-bent wall nail 7 cannot hook onto the crack-resistant mesh 6 and therefore cannot act as a barrier. When the crack-resistant mesh 6 is subjected to an upward force along the wall surface, it is hooked by the bent portion of the downward-bent wall nail 7, preventing it from detaching. Therefore, the bent portion of the downward-bent wall nail 7 acts as a barrier to the crack-resistant mesh 6, while the upward-bent wall nail 7 cannot hook onto it and therefore cannot act as a barrier. By alternating these forces, the crack-resistant mesh 6 can resist external forces acting upward along the wall surface and downward along the front. In other embodiments, the bending direction of the wall nail 7 can also be any other direction, such as left, right, upper right, lower right, etc.

[0032] Reference Figure 4 and Figure 5 The anti-crack mesh 6 has a triangular mesh structure. The triangular structure has stable performance and enhances the anti-deformation ability of the anti-crack mesh 6. When constructing the anti-crack mesh 6, it is convenient to flatly attach the anti-crack mesh 6 to the surface of the wall 1. The anti-crack mesh 6 is not prone to wrinkling. If wrinkles do occur, the wrinkled parts cannot withstand the tension well when the anti-crack mesh 6 is subjected to tension, thus affecting the performance of the anti-crack mesh 6.

[0033] Reference Figure 1 and Figure 6 The outer side of the crack-resistant mesh 6 is covered with a crack-resistant layer 8, as shown in the reference. Figure 7The crack-resistant layer 8 is composed of cement slurry 81 and fiber 82 mixed in a certain proportion. The crack-resistant layer 8 is laid on the outside of the crack-resistant mesh 6. After the cement slurry 81 solidifies, it has high hardness, but its toughness is insufficient. Fiber 82 has high toughness and tensile strength. By adding fiber 82 to the cement slurry 81, the toughness and strength of the crack-resistant layer 8 are enhanced. The crack-resistant layer 8 plays a protective role for the protective mesh on the one hand, and increases the wall 1's ability to resist cracking on the other hand.

[0034] Reference Figure 7 and Figure 8 The fibers 82 in the crack-resistant layer 8 are metal fibers. Compared to ordinary fibers 82, metal fibers have high strength and toughness. In this embodiment, the length of the metal fibers is between 1.5 cm and 4 cm. If the metal fibers are too long, they are prone to knotting, which is not conducive to construction. If the metal fibers are too short, the contact area between a single metal fiber and the cement slurry 81 is small, which will lead to a decrease in the bonding performance between the metal fibers and the cement slurry 81, and the performance of the metal fibers cannot be fully utilized. The diameter of the metal fibers is controlled between 0.05 mm and 0.2 mm, which allows for good deformation capacity while ensuring strength. If the diameter of the metal fibers is too small, the tensile strength that a single metal fiber can withstand will decrease. If the diameter of the metal fibers is too large, the metal fibers will not be easy to bend, which is not conducive to construction. The anti-slip texture 9 on the outer surface of the metal fibers helps to increase the contact area between the metal fibers and the cement slurry 81, increase the friction between the cement slurry 81 and the metal fibers, and improve the bonding performance between the metal fibers and the cement slurry 81. In other embodiments, the length and diameter of the metal fibers can also be other specifications.

[0035] Reference Figure 8 The anti-slip texture 9 is a circular pattern coaxial with the metal fiber, and multiple anti-slip textures 9 are arranged along the axis of the metal fiber. The metal fiber is made of an alloy of copper and iron. The frictional force generated between the metal fiber and the cement slurry 81 is often along the axis of the metal fiber. The circular texture hinders the movement of the metal fiber along its axis, improving the bonding performance between the metal fiber and the cement slurry 81. The copper-iron alloy has strong corrosion resistance, which helps prevent the metal fiber from being corroded and can extend the service life of the wall 1.

[0036] Reference Figure 1 and Figure 6 The crack-resistant layer 8 is coated with an elastic surface layer 10. When minor cracks appear in the wall 1, they generally do not affect the overall performance of the wall 1, but these minor cracks often affect the overall appearance of the wall 1. By applying the elastic surface layer 10 to the outside of the crack-resistant layer 8, when minor cracks appear in the wall 1, the elastic surface layer 10 has a certain degree of elasticity and will not crack, thus ensuring that the overall appearance of the wall 1 is not affected.

[0037] The implementation principle of a wall structure for preventing wall cracking according to an embodiment of this application is as follows: Capsules 3 are added to concrete 2 and thoroughly mixed to ensure complete incorporation. The capsules 3 containing concrete 2 are then poured into a wall 1. After the wall 1 has completely solidified, wall nails 7 are driven into the wall 1 to a depth equal to half the length of the nail. Multiple rows of wall nails 7 are driven in rows and columns. Anti-crack mesh 6 is then laid on the wall surface, passing through the wall nails 7 and resting against the wall surface. Bend the wall nail 7 so that the bent wall nail 7 clamps the anti-crack mesh 6 between the wall nail 7 and the wall surface, so that the bending directions of adjacent wall nails 7 are opposite. Add metal fibers to the cement slurry 81 and stir it thoroughly. Spread the cement slurry 81 with metal fibers on the wall surface so that the cement slurry 81 with metal fibers is fully combined with the anti-crack mesh 6 and the wall nail 7 and is fixed to the wall surface. After the cement slurry 81 with metal fibers has cured, brush the elastic surface layer 10 on the surface of the cement slurry 81.

[0038] Example 2 This application discloses a construction process for preventing wall cracking, which uses the above-mentioned wall structure and involves the following steps: Casting the wall: First, add capsules 3, which are used to bond cracks, to concrete 2 in a certain proportion, and then use the concrete 2 containing capsules 3 to cast the wall 1. Construction of anti-crack mesh: After the concrete 2 has solidified, nail wall nails 7 into the wall 1. When nailing the wall nails 7 into the wall 1, only nail half the length of the wall nail 7. Lay the anti-crack mesh 6 so that the anti-crack mesh 6 passes through the wall nail 7 and abuts against the wall 1. Bend the wall nail 7 and fix the anti-crack mesh 6 to the surface of the wall 1 through the wall nail 7. When bending the wall nail 7, the bending directions of the two adjacent wall nails 7 are opposite, so that one wall nail 7 bends upward and the other adjacent wall nail 7 bends downward. Crack-resistant layer construction: Metal fibers are added to cement slurry 81 and stirred to fully mix the fibers 82 with the cement slurry 81. The cement slurry 81 with fibers 82 is brushed onto the surface of the wall 1 to form a crack-resistant layer 8, and the cement slurry 81 is fully bonded with the wall nails 7 and the crack-resistant mesh 6.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
