Description
Technical Field
[0001] This application relates to the field of building door and window installation technology, and in particular to a device for reinforcing old windows during replacement installation. Background Technology
[0002] In the field of building renovation, replacing old windows is a common engineering requirement. As buildings age or users' requirements for aesthetics and energy efficiency increase, the demand for window replacement is growing.
[0003] In existing technologies, common methods for window installation and reinforcement include the following: First, using expansion bolts to directly fix the window frame to the wall. This method is simple to construct but depends on the load-bearing capacity of the wall. Second, using chemical anchors, which enhance the fixing strength by injecting adhesive, but the construction period is long and is greatly affected by the ambient temperature. The main drawback of existing technologies is that they cannot provide sufficient reinforcement on old walls, and insufficient fixing strength of the window may lead to safety hazards.
[0004] Therefore, this application provides a device for reinforcement during the installation of new windows for old ones. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a reinforcement device for the installation of new windows during replacement, overcoming the deficiencies of existing technologies. The aim is to solve the problems of common window installation reinforcement methods in the prior art, which include: firstly, directly fixing the window frame to the wall using expansion bolts, a simple method that relies on the wall's load-bearing capacity; secondly, using chemical anchors, which enhance the fixing strength by injecting adhesive, but this method has a long construction period and is greatly affected by ambient temperature. The main drawback of existing technologies is that they cannot provide sufficient reinforcement on old walls, and insufficient fixing strength of the window frame may lead to safety hazards.
[0006] To achieve the above objectives, this application provides the following technical solution: a device for reinforcing old windows during replacement installation, comprising a wall and a window frame. The wall has two pre-installed wall fixing components inside. Reinforcing components are provided on both the upper and lower sides of the window frame. Each reinforcing component includes a main support, which is fixedly installed on the outer wall of the window frame. Several sets of anchor bolts connect the main support to the wall fixing components. A secondary support is provided on one side of the main support. Two sets of hinge seats are fixedly installed on the end of the secondary support away from the main support. Two sets of fastening supports are provided on one side of the wall fixing components. A tie rod is hinged between the fastening supports and the corresponding hinge seats.
[0007] By adopting the above technical solution, during installation, the wall fixing components are first embedded in the wall, then the main bracket and the secondary bracket are connected to the window frame, and finally the fastening bracket is connected to the wall fixing components, so that the tie rod, the hinge seat and the wall fixing components form a stable triangular support structure, thereby enhancing the tensile and shear resistance of the window frame, improving the stability of the window after installation and strengthening safety.
[0008] As a preferred technical solution of this application, the main support has two sets of sliding rods internally connected, and one end of each set of sliding rods passes through the main support and is fixedly connected to the secondary support.
[0009] By adopting the above technical solution, the secondary bracket is slidably connected to the main bracket through two sets of sliding rods, which can adjust the horizontal position of the secondary bracket to match the window frame, making it easier to adapt to window frames of different sizes and improving its applicability during use.
[0010] As a preferred technical solution of this application, the wall fixing component includes a pre-embedded plate, which is pre-embedded in the inner wall of the wall. Several sets of chemical anchors are fixedly installed between the pre-embedded plate and the wall. The main bracket is fixedly installed with the corresponding pre-embedded plate through several sets of anchors.
[0011] By adopting the above technical solution, during installation, holes are first drilled in the wall and several sets of chemical anchors are installed. The embedded plate is then firmly fixed in the wall by these chemical anchors. Compared with the traditional expansion bolt fixing method, it is not limited by the single load-bearing capacity of the wall, which is conducive to improving the applicability to old walls and improving the stability of the window frame after installation.
[0012] As a preferred technical solution of this application, the outer ring of the window frame is provided with four sets of reinforcing strips, two sets of the reinforcing strips are respectively fixedly installed on the four sides of the window frame, and the four sets of reinforcing strips are connected end to end in sequence. The reinforcing strips are fixedly installed to the wall by several sets of anchor bolts.
[0013] By adopting the above technical solution, the outer ring of the window frame is connected to the wall at multiple points through four sets of reinforcing strips. The force on the window frame is evenly distributed to the wall through the reinforcing strips, which further improves the stability of the window after installation.
[0014] As a preferred technical solution of this application, the slide bar is a T-shaped slide bar, and the main support has a T-shaped groove inside that matches the slide bar.
[0015] By adopting the above technical solution, and through the design of the T-shaped slide bar and the T-shaped slide groove, the sliding function of the slide bar is guaranteed, and the slide bar is prevented from falling off, thus improving the practicality of the device.
[0016] As a preferred technical solution of this application, a buffer pad layer is fixedly installed between the window frame and the four sets of reinforcing strips, and the buffer pad layer is made of polyurethane foam.
[0017] By adopting the above technical solution, and using a buffer layer made of polyurethane foam, when the window frame is subjected to external force, the buffer layer will undergo elastic deformation to absorb and buffer part of the energy. This helps to avoid damage to the outer wall of the window frame caused by rigid contact between the reinforcement strip and the window frame, and can also absorb vibration stress during the installation process.
[0018] As a preferred technical solution of this application, the bottom end of the embedded plate is fixedly installed with an anti-slip layer.
[0019] By adopting the above technical solution, the anti-slip layer prevents the embedded plate from shifting inside the wall, improving the reliability of the connection between the embedded plate and the wall, and further adapting it to old walls with weak adhesion to the wall base.
[0020] As a preferred technical solution of this application, both the main support and the secondary support are made of carbon fiber material, and the embedded plate is a steel plate.
[0021] By adopting the above technical solution, carbon fiber material has the characteristics of high strength and light weight, which not only meets the strength requirements of the reinforcement components and can withstand various forces on the window frame, but also reduces the weight of the reinforcement components themselves and reduces the burden on the wall. By using steel plates for the embedded plates, the high strength and rigidity of the steel plates are improved, thus improving the stability during installation.
[0022] The beneficial effects of this application are: 1. During installation, the wall fixing components are first embedded in the wall. Then, the main bracket and the secondary bracket are connected to the window frame. Finally, the fastening bracket is connected to the wall fixing components, so that the tie rod, the hinge seat and the wall fixing components form a stable triangular support structure, thereby enhancing the tensile and shear resistance of the window frame, improving the stability of the window after installation and strengthening safety.
[0023] 2. The secondary bracket is slidably connected to the main bracket through two sets of sliding rods, which can adjust the horizontal position of the secondary bracket to match the window frame, making it suitable for window frames of different sizes and improving its applicability during use.

Two sets of wall fixing components 3 are pre-installed inside the wall 1. Reinforcing components 4 are installed on both the upper and lower sides of the window frame 2. Each reinforcing component 4 includes a main support 401, which is fixedly installed on the outer wall of the window frame 2. Several sets of anchor bolts 407 connect the main support 401 to the wall fixing components 3. A secondary support 402 is located on one side of the main support 401, away from the main support 401. Two sets of hinge seats 405 are fixedly installed at one end, and two sets of fastening supports 404 are provided on one side of the wall fixing component 3. A tie rod 406 is hinged between the fastening support 404 and the corresponding hinge seat 405. The wall fixing component 3 includes a pre-embedded plate 301, which is pre-embedded in the inner wall of the wall 1. Several sets of chemical anchor bolts 302 are fixedly installed between the pre-embedded plate 301 and the wall 1. The main bracket 401 is fixedly installed with the corresponding pre-embedded plate 301 through several sets of anchor bolts 407.
[0028] During installation, the wall fixing component 3 is first embedded inside the wall 1. Then, the main bracket 401 and the secondary bracket 402 are connected to the window frame 2. Finally, the fastening support 404 is connected to the wall fixing component 3, so that the tie rod 406, the hinge seat 405, and the wall fixing component 3 form a stable triangular support structure, thereby enhancing the tensile and shear resistance of the window frame 2, improving the stability of the window after installation, and strengthening safety. During installation, holes are first drilled in the wall 1 and several sets of chemical anchor bolts 302 are installed. The embedded plate 301 is firmly fixed in the wall 1 by several sets of chemical anchor bolts 302. Compared with the traditional expansion bolt fixing method, it is not limited by the single load-bearing capacity of the wall, which is conducive to improving the applicability to old walls and improving the stability of the window frame 2 after installation.
[0029] Reference Figure 1-3 The main support 401 has two sets of sliding rods 403 internally connected. One end of each set of sliding rods 403 passes through the main support 401 and is fixedly connected to the secondary support 402. The outer ring of the window frame 2 is provided with four sets of reinforcing strips 5. The two sets of reinforcing strips 5 are fixedly installed on the four sides of the window frame 2 respectively, and the four sets of reinforcing strips 5 are connected end to end in sequence. The reinforcing strips 5 are fixedly installed to the wall 1 by several sets of anchor bolts 6. The secondary bracket 402 is slidably connected to the main bracket 401 through two sets of sliding rods 403, which can adjust the horizontal position of the secondary bracket 402 to match the window frame 2, which is beneficial to adapt to window frames 2 of different sizes and improves the applicability during use; the outer ring of the window frame 2 is connected to the wall 1 at multiple points through four sets of reinforcing strips 5, and the force on the window frame 2 is evenly distributed to the wall 1 through the reinforcing strips 5, which further improves the stability of the window after installation.
[0030] Reference Figure 2-5 The slide rod 403 is a T-shaped slide rod, and the main support 401 has a T-shaped groove inside that matches the slide rod 403; the bottom end of the embedded plate 301 is fixedly installed with an anti-slip layer 8; through the design of the T-shaped slide rod and the T-shaped groove, the sliding function of the slide rod 403 is guaranteed, and the slide rod 403 is prevented from falling off, thus improving the practicality of the device; the anti-slip layer 8 prevents the embedded plate 301 from shifting inside the wall 1, improving the reliability of the connection between the embedded plate 301 and the wall 1, and further adapting it to old walls with weak adhesion of the wall base.
[0031] Reference Figure 2-5A buffer layer 7, made of polyurethane foam, is fixedly installed between the window frame 2 and the four sets of reinforcing strips 5. The main support 401 and the secondary support 402 are both made of carbon fiber, and the embedded plate 301 is made of steel plate. Because the buffer layer 7 is made of polyurethane foam, when the window frame 2 is subjected to external force, the buffer layer 7 will undergo elastic deformation to absorb and buffer part of the energy, which helps to avoid damage to the outer wall of the window frame 2 caused by rigid contact between the reinforcing strips 5 and the window frame 2. At the same time, it can absorb the vibration stress during the installation process. The carbon fiber material has the characteristics of high strength and light weight, which not only meets the strength requirements of the reinforcing component 4 and can withstand various forces on the window frame 2, but also reduces the weight of the reinforcing component 4 itself and reduces the burden on the wall 1. The embedded plate 301 is made of steel plate, which has high strength and rigidity, improving the stability during installation.
[0032] Working principle: During installation, the wall fixing component 3 is first embedded in the wall 1. Then, the main bracket 401 and the secondary bracket 402 are connected to the window frame 2. Finally, the fastening support 404 is connected to the wall fixing component 3, so that the tie rod 406, the hinge seat 405 and the wall fixing component 3 form a stable triangular support structure, thereby enhancing the tensile and shear resistance of the window frame 2, improving the stability of the window after installation and strengthening safety. The secondary bracket 402 is slidably connected to the main bracket 401 through two sets of sliding rods 403, which can adjust the horizontal position of the secondary bracket 402 to match the window frame 2, which is beneficial to adapt to window frames 2 of different sizes and improves the applicability during use. During installation, holes are first drilled in the wall 1 and several sets of chemical anchors 302 are installed. The embedded plate 301 is then firmly fixed in the wall 1 by the chemical anchors 302. Compared with the traditional expansion bolt fixing method, it is not limited by the single load-bearing capacity of the wall, which is conducive to improving the applicability to old walls and improving the stability of the window frame 2 after installation. The outer ring of the window frame 2 is connected to the wall 1 at multiple points by four sets of reinforcing strips 5. The force on the window frame 2 is evenly distributed to the wall 1 through the reinforcing strips 5, which further improves the stability of the window after installation. Meanwhile, the design of the T-shaped sliding rod and T-shaped sliding groove not only ensures the sliding function of the sliding rod 403, but also prevents the sliding rod 403 from falling off, thus improving the practicality of the device; since the buffer layer 7 is made of polyurethane foam, when the window frame 2 is subjected to external force, the buffer layer 7 will undergo elastic deformation to absorb and buffer part of the energy, which helps to avoid damage to the outer wall of the window frame 2 caused by rigid contact between the reinforcing strip 5 and the window frame 2, and can also absorb the vibration stress during the installation process; In addition, the anti-slip layer 8 prevents the embedded plate 301 from shifting inside the wall 1, improving the reliability of the connection between the embedded plate 301 and the wall 1, and further adapting it to old walls with weak adhesion to the wall base. The carbon fiber material has the characteristics of high strength and light weight, which not only meets the strength requirements of the reinforcement component 4 and can withstand various forces on the window frame 2, but also reduces the weight of the reinforcement component 4 itself, reducing the burden on the wall 1. The embedded plate 301 is a steel plate, which has high strength and rigidity, improving the stability during installation.
