Description

Technical Field

[0001] This application relates to the field of crack-resistant devices, and in particular to crack-resistant devices for window corner structural walls. Background Technology

[0002] Stone curtain walls are the first line of defense for building exterior insulation, heat insulation, and waterproofing. The double-layer building skin has a good sun shading effect, and the space between the two layers can create a good airflow effect, which can remove the excess heat from the building skin and reduce indoor air conditioning energy consumption.

[0003] The existing system suffers from an overly dense arrangement of reinforcing bars, resulting in too many fixing points at the window corners, which negatively impacts overall stability. Under the influence of external forces and human factors, the reinforcing bars above the window sill are prone to sinking, causing the protective layer thickness to exceed the standard. This not only affects the appearance of the concrete window sill but also increases the risk of cracking, thereby reducing the service life and safety of the entire structure.

[0004] Therefore, a new approach is needed to solve this problem. Utility Model Content

[0005] The purpose of this application is to provide a crack-resistant device for window corner structural walls, which has the advantages of increasing connection strength and ensuring durability. It solves the problem that existing devices have too many fixing points at the window corner due to the overly dense arrangement of steel bars, which affects the overall stability. Under the influence of external forces and human factors, the steel bars above the window sill are prone to sinking, causing the protective layer thickness to exceed the standard. This situation not only affects the appearance of the concrete window sill, but also increases the risk of cracking of the concrete window sill, thereby reducing the service life and safety of the entire structure.

[0006] The anti-crack device for window corner structural walls provided in this application adopts the following technical solution: it includes a frame, the outer side of which is provided with a number of additional steel bars and a number of second tie straps, and the inner side of which is provided with a number of reinforcing bars. Each additional steel bar includes a fixed steel bar, two bent steel bars and two tensile steel bars. The outer surface of each tensile steel bar is fixedly connected to the corresponding bent steel bar, and the end of each bent steel bar away from the corresponding tensile steel bar is fixedly connected to the corresponding fixed steel bar.

[0007] By adopting the above technical solution, the frame serves as the overall supporting structure, connecting internal and external reinforcing components to ensure the compatibility of the device with the wall. Simultaneously, it provides a fixed reference for the additional reinforcing bars and ribs, ensuring the stability of force transmission in each component. The additional reinforcing bars enhance the tensile and shear strength of the wall exterior, disperse concentrated stress at the window corners, and prevent cracks caused by external forces or temperature deformation from spreading outwards. The second tie assists in fixing the additional reinforcing bars, ensuring they do not shift during construction and wall use, guaranteeing a reliable connection with the frame and wall, and maintaining the reinforcement effect. The ribs are placed at an angle to strengthen the wall at the window corners. The internal structure strengthens the structure, balances the differences in internal and external forces, and reduces internal stress caused by internal shrinkage or uneven stress in the wall, thus inhibiting crack initiation from the inside. The fixed reinforcing bars, bent reinforcing bars, and tensile reinforcing bars are integrally formed. The bent reinforcing bars serve as transitional components for the additional reinforcing bars, achieving a smooth connection between the tensile reinforcing bars and the fixed reinforcing bars, avoiding stress concentration caused by the bending of the reinforcing bars, and transferring the stress borne by the tensile reinforcing bars to the fixed reinforcing bars. By adopting a hook design, the connection between the reinforcing bars is enhanced. Through this improvement, the connection between the reinforcing bars is more robust, and it can better withstand various external forces and loads, ensuring construction quality and the long-term durability of the project.

[0008] Preferably, the frame includes a plurality of vertical reinforcing bars, horizontal reinforcing bars, and a first tie.

[0009] By adopting the above technical solution, the vertical reinforcing bars are arranged along the height of the wall, consistent with the vertical force direction of the wall, bearing the vertical load of the window corner wall, resisting vertical deformation, and providing vertical fixing nodes for the horizontal reinforcing bars and additional components, ensuring the vertical stiffness of the frame. The horizontal reinforcing bars are arranged along the horizontal direction of the wall, intersecting with the vertical reinforcing bars to form a grid. The first tie is tied at the intersection of the vertical and horizontal reinforcing bars, ensuring that the grid structure does not loosen by fixing the vertical and horizontal reinforcing bars, ensuring the stability of the frame during use, and avoiding frame failure due to reinforcing bar displacement.

[0010] Preferably, the outer surface of each of the transverse reinforcing bars is in contact with the corresponding vertical reinforcing bar.

[0011] By adopting the above technical solution, the design of the outer surface of the horizontal steel bar contacting the corresponding vertical steel bar is the basis for the frame to form a stable grid structure. It ensures that the two form a close-fitting connection at the intersection, providing a stable foundation for the binding and fixing of the first tie. The first tie can tightly bind the two contacting steel bars with the tightening force, avoiding loosening or relative sliding after binding due to gaps, thereby ensuring the rigidity of each intersection node and making the frame grid less prone to deformation.

[0012] Preferably, the outer surface of each of the first cable ties is fixedly installed with the corresponding transverse and vertical reinforcing bars.

[0013] By adopting the above technical solution, the first cable tie, through its outer surface, tightly adheres to and secures the two contacting steel bars, upgrading the intersection of the horizontal and vertical steel bars from mere contact to rigid fixation. The horizontal steel bars cannot slide along the vertical steel bars, and the vertical steel bars cannot shift relative to the horizontal steel bars, completely eliminating the relative displacement freedom of the nodes in the horizontal and vertical directions. This makes each grid unit an indivisible whole, significantly improving the overall stiffness of the frame. The first cable tie fixing operation is simple and fast, suitable for batch operations on site, and facilitates the adjustment of steel bar positions, reducing construction errors.

[0014] Preferably, the outer surface of each second cable tie is fixedly installed with the transverse reinforcing bar and the corresponding additional reinforcing bar.

[0015] By adopting the above technical solution, the tensile stress borne by the additional reinforcing bars needs to be transferred to the frame through bending and fixing of the reinforcing bars. The bidirectional fixing of the second tie further strengthens this path. By tightly binding the additional reinforcing bars with the transverse reinforcing bars, it ensures that the additional reinforcing bars do not shift locally or detach from the frame when under stress, so that the tensile stress can be directly transferred to the grid structure of the frame through the second tie, avoiding the interruption of stress transfer due to loosening of the reinforcing bars. The additional reinforcing bars are located on the outside of the frame and are prone to transverse or vertical displacement due to wall deformation or construction vibration. The second tie restricts the rotation and sliding of the additional reinforcing bars in the plane by fixing them with the transverse reinforcing bars and the additional reinforcing bars, so that they always maintain the designed stress angle and ensure that the tensile reinforcing bars can accurately bear the tensile stress in the preset direction.

[0016] Preferably, the outer surface of each reinforcing rib is in contact with the frame, and the outer surface of each reinforcing rib is fixedly installed with a corresponding first cable tie and second cable tie.

[0017] By adopting the above technical solution, the outer surface of the reinforcing rib is in direct contact with the frame. It can directly bear the stress transmitted by the frame through the contact surface, and at the same time transmit the internal shrinkage stress it bears to the frame. This contact design avoids the force transmission delay caused by the existence of gaps, so that the reinforcing rib and the frame form a rigid linkage and jointly constrain the internal deformation of the wall. By using the rigidity of the first tie at the frame node, the reinforcing rib is anchored at the intersection of the frame, restricting its horizontal and vertical displacement and ensuring that the reinforcing rib plays a constraining role along the design path. Through the connection between the second tie and the outer additional steel bar, the reinforcing rib and the outer reinforcement system form a lateral tie. When the outer additional steel bar is under tension, the second tie can drive the reinforcing rib to generate reverse constraint, balance the force difference between the inner and outer sides, and avoid the wall from eccentric deformation due to excessive force on one side.

[0018] Preferably, each of the reinforcing ribs has a number of quincunx clips attached to its outer surface.

[0019] By adopting the above technical solution, the multi-claw structure of the plum blossom clip can form a uniform clamping force from the outer periphery of the reinforcing bar, so that there is no relative sliding between the reinforcing bar and the plum blossom clip. At the same time, the bottom of the plum blossom clip can fit with the steel bars of the frame or the wall formwork, fixing the position of the reinforcing bar at the design elevation and plane position, preventing it from shifting due to external forces during concrete pouring and vibration, and ensuring that the reinforcing bar is always in the effective stress area to achieve rigid positioning. By setting the plum blossom clip in the non-node area of ​​the reinforcing bar, it can prevent it from bending or shaking in the middle due to excessive slenderness ratio, ensuring that the reinforcing bar is in a straight state under stress, and improving its resistance efficiency to shrinkage stress on the inner side of the wall.

[0020] Preferably, each of the tensile reinforcement bars is placed perpendicular to the corresponding fixed reinforcement bar.

[0021] By adopting the above technical solution, with the vertical layout of tensile reinforcement and fixed reinforcement, the bending angle of the bent reinforcement does not need to be adjusted. This can minimize stress concentration caused by bending angle deviation, ensure efficient transmission of tensile stress along the reinforcement axis, avoid the additional reinforcement itself from breaking due to uneven stress, and improve the stress efficiency of tensile reinforcement.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This anti-crack device for window corner structural walls, through the setting of components such as a frame, additional reinforcing bars, a second tie, reinforcing bars, fixed reinforcing bars, bent reinforcing bars, tensile reinforcing bars, and fixed reinforcing bars, enhances the bonding effect between reinforcing bars through the hook design of the tensile reinforcing bars in the additional reinforcing bars. Through this improvement, the connection between reinforcing bars is more solid, which can better withstand various external forces and loads, ensuring construction quality and long-term durability of the project. In this way, the device can effectively reduce the impact of external forces and more accurately control the thickness of the window sill protective layer. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: Crack-resistant device for window corner structural wall, refer to Figure 1 , Figure 2 , Figure 3 The frame includes a frame 1. The outer side of the frame 1 is provided with several additional reinforcing bars 3 and several second tie 4. The inner side of the frame 1 is provided with several reinforcing bars 5. Each additional reinforcing bar 3 includes a fixed reinforcing bar 303, two bent reinforcing bars 302 and two tensile reinforcing bars 301. The outer surface of each tensile reinforcing bar 301 is fixedly connected to the corresponding bent reinforcing bar 302. The end of each bent reinforcing bar 302 away from the corresponding tensile reinforcing bar 301 is fixedly connected to the corresponding fixed reinforcing bar 303.

[0027] like Figure 2 , Figure 3 Frame 1 serves as the overall supporting structure, connecting internal and external reinforcing components to ensure the compatibility of the device with the wall. It also provides a fixing reference for the additional reinforcing bars 3 and ribs 5, ensuring the stability of force transmission across all components. The additional reinforcing bars 3 enhance the tensile and shear strength of the wall exterior, disperse concentrated stress at the window corner, and prevent cracks caused by external forces or temperature deformation from spreading outwards. The second cable tie 4 assists in fixing the additional reinforcing bars 3, ensuring they do not shift during construction and wall use, guaranteeing a reliable connection with frame 1 and the wall, and maintaining the reinforcement effect. The ribs 5, placed at an angle, strengthen the internal structure of the window corner wall and balance internal and external forces. The design reduces internal stress caused by shrinkage or uneven stress within the wall, thus inhibiting crack initiation from the inside. The fixed reinforcing bar 303, bent reinforcing bar 302, and tensile reinforcing bar 301 are integrally formed. The bent reinforcing bar 302 serves as a transitional component for the additional reinforcing bar 3, achieving a smooth connection between the tensile reinforcing bar 301 and the fixed reinforcing bar 303. This avoids stress concentration caused by the bending of the reinforcing bars and simultaneously transfers the stress borne by the tensile reinforcing bar 301 to the fixed reinforcing bar 303. The use of a hook design enhances the bonding effect between the reinforcing bars. Through this improvement, the connection between the reinforcing bars is more robust, enabling them to better withstand various external forces and loads, ensuring construction quality and the long-term durability of the project.

[0028] Example 2: Crack-resistant device for window corner structural walls, please refer to [link / reference]. Figure 4 , Figure 5The frame 1 includes several vertical reinforcing bars 101, horizontal reinforcing bars 102, and a first tie 2. The vertical reinforcing bars 101 are arranged along the height of the wall and are consistent with the vertical force direction of the wall. They bear the vertical load of the window corner wall and resist vertical deformation. At the same time, they provide vertical fixing nodes for the horizontal reinforcing bars 102 and additional components to ensure the vertical stiffness of the frame 1. The horizontal reinforcing bars 102 are arranged along the horizontal direction of the wall and intersect with the vertical reinforcing bars 101 to form a grid. The first tie 2 is tied at the intersection of the vertical reinforcing bars 101 and the horizontal reinforcing bars 102. By fixing the vertical reinforcing bars 101 and the horizontal reinforcing bars 102, the grid structure is ensured to remain stable and the frame 1 is stable during use, avoiding frame 1 failure due to reinforcing bar displacement.

[0029] Please see Figure 5 The outer surface of each horizontal reinforcing bar 102 is in contact with the corresponding vertical reinforcing bar 101. The design of the outer surface of the horizontal reinforcing bar 102 in contact with the corresponding vertical reinforcing bar 101 is the basis for the stable grid structure of the frame 1. It ensures that the two form a tight fit at the intersection, providing a stable foundation for the binding and fixing of the first tie 2. The first tie 2 can tightly bind the two contacting reinforcing bars with the tightening force, avoiding loosening or relative sliding after binding due to gaps, thereby ensuring the rigidity of each intersection node and making the grid of the frame 1 less prone to deformation.

[0030] Please see Figure 4 , Figure 5 Each first cable tie 2 has its outer surface fixed to the corresponding horizontal reinforcing bar 102 and vertical reinforcing bar 101. The first cable tie 2, through its outer surface, tightly fits and fastens the two contacting reinforcing bars, upgrading the intersection of the horizontal reinforcing bar 102 and the vertical reinforcing bar 101 from merely contacting to rigidly fixed. The horizontal reinforcing bar 102 cannot slide along the vertical reinforcing bar 101, and the vertical reinforcing bar 101 cannot shift relative to the horizontal reinforcing bar 102. This completely eliminates the relative displacement freedom of the node in the horizontal and vertical directions, making each grid unit an indivisible whole. The overall stiffness of the frame 1 is significantly improved. The fixing operation through the first cable tie 2 is simple and fast, suitable for batch operations on site, and facilitates the adjustment of the reinforcing bar position, reducing construction errors.

[0031] Please see Figure 1 , Figure 2 , Figure 3Each second cable tie 4 has its outer surface fixedly installed with the transverse steel bar 102 and the corresponding additional steel bar 3. The tensile stress borne by the tensile steel bar 301 of the additional steel bar 3 needs to be transferred to the frame 1 through the bent steel bar 302 and the fixed steel bar 303. The bidirectional fixation of the second cable tie 4 further strengthens this path. By tightly binding the additional steel bar 3 with the transverse steel bar 102, it ensures that the additional steel bar 3 does not shift locally or detach from the frame 1 when under stress, so that the tensile stress can be directly transferred to the grid structure of the frame 1 through the second cable tie 4, avoiding the interruption of stress transmission due to the loosening of the steel bar. The additional steel bar 3 is located on the outside of the frame 1 and is prone to transverse or vertical displacement due to wall deformation or construction vibration. The second cable tie 4 restricts the rotation and sliding of the additional steel bar 3 in the plane by fixing it with the transverse steel bar 102 and the additional steel bar 3, so that it always maintains the designed stress angle and ensures that the tensile steel bar 301 can accurately bear the tensile stress in the preset direction.

[0032] Please see Figure 3 , Figure 4 Each reinforcing rib 5 has its outer surface in contact with the frame 1, and each reinforcing rib 5 is fixedly installed with the corresponding first cable tie 2 and second cable tie 4. The outer surface of the reinforcing rib 5 is in direct contact with the frame 1, and it can directly bear the stress transmitted by the frame 1 through the contact surface, while transmitting the internal shrinkage stress it bears to the frame 1. This contact design avoids the delay in force transmission caused by the existence of gaps, so that the reinforcing rib 5 and the frame 1 form a rigid linkage, jointly constraining the internal deformation of the wall. By using the rigidity of the first cable tie 2 at the node of the frame 1, the reinforcing rib 5 is anchored at the intersection node of the frame 1, restricting its horizontal and vertical displacement, and ensuring that the reinforcing rib 5 plays a constraining role along the design path. Through the connection between the second cable tie 4 and the outer additional steel bar 3, the reinforcing rib 5 and the outer reinforcement system form a transverse tie. When the outer additional steel bar 3 is under tension, the second cable tie 4 can drive the reinforcing rib 5 to generate reverse constraint, balance the difference in force between the inner and outer sides, and avoid the wall from eccentric deformation due to excessive force on one side.

[0033] Please see Figure 3 , Figure 4 Each reinforcing rib 5 has several quincunx clips 6 attached to its outer surface. The multi-claw structure of the quincunx clips 6 can form a uniform clamping force from the outer periphery of the reinforcing rib 5, so that there is no relative sliding between the reinforcing rib 5 and the quincunx clips 6. At the same time, the bottom of the quincunx clips 6 can fit with the steel bars of the frame 1 or the wall formwork, fixing the position of the reinforcing rib 5 at the design elevation and plane position, preventing it from shifting due to external forces during concrete pouring and vibration, and ensuring that the reinforcing rib 5 is always in the effective stress area to achieve rigid positioning. By setting quincunx clips 6 in the non-node areas of the reinforcing rib 5, it can prevent it from bending or shaking in the middle due to excessive slenderness ratio, ensuring that the reinforcing rib 5 is in a straight state under stress, and improving its resistance efficiency to shrinkage stress on the inner side of the wall.

[0034] Please see Figure 2 Each tensile steel bar 301 is placed perpendicularly to the corresponding fixed steel bar 303. With the vertical arrangement of the tensile steel bar 301 and the fixed steel bar 303, the bending angle of the bent steel bar 302 does not need to be adjusted. This can minimize the stress concentration caused by the bending angle deviation, ensure that the tensile stress is efficiently transmitted along the steel bar axis, avoid the additional steel bar 3 from breaking due to uneven stress, and improve the stress efficiency of the tensile steel bar 301.

[0035] The implementation principle of this application embodiment is as follows: First, the vertical steel bar 101 and the horizontal steel bar 102 are placed vertically and then fixed with the first cable tie 2. This step establishes a rigid grid by contacting the cable tie, providing a reference for subsequent components. Then, the tensile steel bar 301, the bent steel bar 302, and the fixed steel bar 303 are formed into a vertical assembly and fixed to the outside of the frame 1 by using the second cable tie 4. This ensures that the additional steel bar 3 is aligned with the stress direction and establishes an outer tensile path. By adopting a hook design, the connection between the steel bars is enhanced. Through this improvement, the connection between the steel bars is more solid and can better withstand various external forces and loads, ensuring construction quality and long-term durability of the project. Then, the reinforcing bar 5 is attached to the inside of the frame 1 and the nodes are fixed with the first cable tie 2 and the second cable tie 4. Then, the quincunx clip 6 is snapped along the reinforcing bar 5 to complete the inner constraint system. The quincunx clip 6 ensures the accurate positioning of the reinforcing bar 5. Through the combination of the frame 1, the additional steel bar 3, the reinforcing bar 5 and the concrete, the quincunx clip 6 and the concrete interlocking force are strengthened and coordinated to achieve the overall stress of the steel bar, concrete and frame. The device then officially plays its anti-cracking role.
