Description

Technical Field

[0001] This application relates to the technical field of industrial building renovation, and in particular to a structure and method for reinforcing the exterior walls of industrial buildings. Background Technology

[0002] Urban development inevitably leaves behind some old industrial buildings. If these buildings are abandoned or demolished, it will cause irreversible damage to the city's cultural heritage. The purpose of industrial building renovation is to combine the characteristics of urban development, turn these industrial buildings into "treasures," and inject new vitality into them. The renovation of industrial buildings is a continuation of the city's industrial era memory. Preserving their external features can evoke people's memories of the industrial era. Therefore, the renovation of industrial buildings will preserve the original characteristics of the buildings. For the aging and dilapidated parts of old buildings, renovation and reinforcement can be carried out to preserve the historical feel of the buildings as much as possible, so that the external form of the old buildings can be better accepted by the public today while retaining their industrial era characteristics.

[0003] Currently, most reinforcement devices for the exterior walls of industrial buildings adopt baffle structures. By installing and fixing baffles on the outside of the wall, the baffles provide support for one side of the exterior wall. However, the seismic resistance of industrial building exterior walls using baffle structures is limited, and the walls still face the risk of collapse during an earthquake. Summary of the Invention

[0004] To improve the seismic performance of the walls after industrial building renovation, this application provides a structure and method for reinforcing the exterior walls of industrial building renovation.

[0005] Firstly, this application provides an external wall reinforcement structure for industrial building renovation, which adopts the following technical solution:

[0006] An industrial building exterior wall reinforcement structure includes a reinforcement frame installed on the inner side of the wall, a stabilizing frame installed on the outer side of the wall, and multiple tie rods penetrating the wall. The reinforcement frame is provided with a first fixing component for fixing the reinforcement frame to a column on the inner side of the wall. The stabilizing frame has multiple mounting holes for the tie rods to pass through, and each mounting hole corresponds to a tie rod. A pressure plate is fixedly installed on each tie rod, and the pressure plate is used to press the side wall of the stabilizing frame away from the wall. The reinforcement frame is provided with a second fixing component for fixing each of the tie rods.

[0007] By adopting the above technical solution, the installation positions of the stabilizing frame are marked on the outer wall of the wall. According to the position of each mounting hole on the stabilizing frame, holes are drilled in the corresponding positions of the wall. The stabilizing frame is installed on the outer side of the wall, and each mounting hole on the stabilizing frame corresponds to the hole drilled in the wall. The stabilizing frame is then pre-fixed. The reinforcement frame is installed on the inner side of the wall and its position is adjusted. Then, the reinforcement frame is fixed to the column on the inner side of the wall using the first fixing component. Tie rods are inserted into each mounting hole on the stabilizing frame, and the tie rods pass through the corresponding holes drilled in the wall. The pressure plate on the tie rod is pressed against the side wall of the stabilizing frame away from the wall. Then, the tie rods are fixed to the reinforcement frame using the second fixing component. This completes the reinforcement of the exterior wall of the industrial building. By strengthening the connection between the wall and the column of the industrial building through the reinforcement frame, stabilizing frame, and tie rods, the seismic performance of the wall after the industrial building renovation is greatly improved.

[0008] Optionally, the first fixing component includes a fixing frame fixedly mounted on the reinforcing frame and a clamping frame slidably mounted on the fixing frame. A clamping area for clamping the column is formed between the fixing frame and the clamping frame. A limiting member for preventing the clamping frame from sliding is provided on the fixing frame.

[0009] Optionally, the limiting component includes a pull screw, both sides of which are provided with external threads. The fixing frame and the clamping bracket are provided with through holes for the pull screw to pass through. Nuts are respectively fitted on the external threads on both sides of the pull screw.

[0010] Optionally, both the fixing frame and the clamping frame are provided with anchors at their respective ends that are close to each other, and the anchors are used to be embedded in the column body.

[0011] Optionally, the second fixing component includes a connecting frame, a threaded sleeve, and a fixing member. The connecting frame is slidably mounted on the reinforcing frame, the threaded sleeve is rotatably mounted on the connecting frame, and the pull rod has an external thread on the side wall away from the pressure plate that is compatible with the threaded sleeve. The fixing member is used to prevent the connecting frame from sliding.

[0012] Optionally, the tie rod has a grouting cavity inside, a grouting port communicating with the grouting cavity on the tie rod, and a number of grout outlet holes communicating with the grouting cavity on the side wall of the tie rod.

[0013] By adopting the above technical solution, after the wall is reinforced, sealing mortar is injected into the grouting cavity of the tie rod through the grouting port. The sealing mortar flows out through the grout outlet hole to seal the gap between the wall and the tie rod, thus ensuring the thermal insulation and sealing performance of the wall.

[0014] Optionally, it also includes a first sealing ring and a second sealing ring fitted on the tie rod. The first sealing ring is used to install between the stabilizer and the outer wall of the wall, and the second sealing ring is used to install between the threaded sleeve and the inner wall of the wall. The first sealing ring and the second sealing ring are respectively used to abut against both ends of the wall.

[0015] Secondly, this application provides a construction method for reinforcing the exterior walls of industrial buildings, employing the following technical solution:

[0016] A construction method for reinforcing the exterior walls of an industrial building includes the following steps:

[0017] S1. Wall opening: Mark the installation position of the stabilizing frame on the outer wall and make openings in the corresponding positions of the wall according to the position of each mounting hole on the stabilizing frame.

[0018] S2. Installation of the stabilizing frame: Install the stabilizing frame on the outside of the wall, ensuring that each mounting hole on the stabilizing frame corresponds to the hole opened on the wall, and pre-fix the stabilizing frame.

[0019] S3. Reinforcement frame installation: Install the reinforcement frame on the inside of the wall and adjust its position. Then fix the reinforcement frame to the column on the inside of the wall.

[0020] S4. Tie rod installation: Insert tie rods into the mounting holes on the stabilizing frame. The tie rods pass through the corresponding holes opened on the wall. The pressure plate on the tie rod is pressed against the side wall of the stabilizing frame away from the wall. Then, fix each tie rod to the reinforcement frame to complete the reinforcement of the building wall.

[0021] S5. Sealing treatment: Fill all openings in the wall with sealing mortar to seal the gaps between the wall and the tie rod.

[0022] Optionally, before installation, a pre-embedded groove is opened on the outer wall of the wall to stabilize the frame. During installation, the frame is embedded in the pre-embedded groove on the outer wall. After the reinforcement structure is installed, cement mortar is poured into the pre-embedded groove to embed the frame.

[0023] Optionally, after the building walls are reinforced, a curtain wall can be installed on the outside of the walls, and a stabilizing frame can be used as the supporting skeleton for the curtain wall.

[0024] In summary, this application has the following beneficial technical effects:

[0025] 1. Mark the installation positions of the stabilizing frame on the outer wall of the building. According to the positions of the mounting holes on the stabilizing frame, drill holes in the corresponding positions on the wall. Install the stabilizing frame on the outer wall, ensuring that each mounting hole on the stabilizing frame corresponds to the hole drilled in the wall. Pre-fix the stabilizing frame. Install the reinforcement frame on the inner wall and adjust its position. Then, fix the reinforcement frame to the column on the inner wall using the first fixing component. Insert tie rods into each mounting hole on the stabilizing frame, passing through the corresponding holes drilled in the wall. The pressure plate on the tie rod is pressed against the side wall of the stabilizing frame away from the wall. Then, fix each tie rod to the reinforcement frame using the second fixing component. This completes the reinforcement of the exterior wall of the industrial building. By strengthening the connection between the wall and the column of the industrial building through the reinforcement frame, stabilizing frame, and tie rods, the seismic performance of the wall after the industrial building renovation is greatly improved.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses an external wall reinforcement structure for industrial building renovation.

[0035] Example 1

[0036] Reference Figure 1 An industrial building renovation exterior wall reinforcement structure includes a reinforcement frame 1 installed on the inner side of the wall, a stabilizing frame 2 installed on the outer side of the wall, and a plurality of tie rods 3 penetrating the wall. The reinforcement frame 1 is provided with a first fixing component for fixing the reinforcement frame 1 to the inner side column of the wall, and the reinforcement frame 1 is provided with a second fixing component for fixing each tie rod 3.

[0037] Reference Figure 1 , 2 The stabilizing frame 2 is a rectangular frame with multiple mounting holes 21 for the pull rods 3 to pass through. The mounting holes 21 correspond one-to-one with the pull rods 3. In this embodiment, one stabilizing frame 2 corresponds to four pull rods 3, and the four mounting holes 21 are respectively opened at the four corners of the stabilizing frame 2. In other embodiments, one stabilizing frame 2 can correspond to any number of pull rods 3.

[0038] Reference Figure 1 , 2 One end of the pull rod 3 is fixedly provided with a pressure plate 31. The length direction of the pull rod 3 is perpendicular to the pressure plate 31. Before installation, the installation position of the stabilizer 2 is marked on the outer wall of the wall, and a pre-embedded groove is opened on the outer wall of the wall. According to the position of each mounting hole 21 on the stabilizer 2, holes are opened at the corresponding positions in the wall. When installing the stabilizer 2, the stabilizer 2 is installed on the outer side of the wall and embedded in the pre-embedded groove opened on the outer side of the wall. Each mounting hole 21 on the stabilizer 2 corresponds to the hole opened on the wall. The pull rod 3 is inserted into each mounting hole 21 on the stabilizer 2. The pull rod 3 passes through the corresponding hole opened on the wall. The pressure plate 31 on the pull rod 3 abuts against the side wall of the stabilizer 2 away from the wall.

[0039] After the reinforcement structure is installed, cement mortar is poured into the pre-embedded groove on the outside of the wall, and the stabilizing frame 2 is pre-embedded in the pre-embedded groove; this avoids the stabilizing frame 2 being exposed to the air for a long time, which would cause the stabilizing frame 2 to age. After the cement mortar in the pre-embedded groove has solidified, plastering can be carried out on the outside of the wall, thus ensuring the aesthetics of the building after the renovation.

[0040] Reference Figure 3The first fixing component includes a fixing frame 11 fixedly mounted on the reinforcing frame 1 and a clamping frame 12 slidably mounted on the fixing frame 11. A guide rod 121 is fixedly mounted on the clamping frame 12 and slides with the fixing frame 11. A clamping interval 13 for clamping the column is formed between the fixing frame 11 and the clamping frame 12. A limiting member for preventing the clamping frame 12 from sliding is provided on the fixing frame 11. The limiting member includes a pull screw 14. Both sides of the pull screw 14 are provided with external threads. Both the fixing frame 11 and the clamping frame 12 are provided with through holes for the pull screw 14 to pass through. Nuts are respectively fitted on the external threads on both sides of the pull screw 14.

[0041] During installation, the reinforcement frame 1 is installed on the inside of the wall and its position is adjusted so that the fixing frame 11 and the clamping frame 12 are clamped on the column inside the wall. A tie rod 14 is installed between the fixing frame 11 and the clamping frame 12, with both ends of the tie rod 14 passing through the through holes on the fixing frame 11 and the clamping frame 12 respectively. Nuts are threaded onto both ends of the tie rod 14 and tightened to fix the reinforcement frame 1 to the column inside the wall.

[0042] Reference Figure 3 Anchors 15 are provided at the ends of the fixed frame 11 and the clamping frame 12 that are close to each other. In this embodiment, the anchors 15 are in the shape of a quadrangular prism. In other embodiments, the anchors 15 can be of any shape. Before installation, slots are opened at corresponding positions on both sides of the column. When the fixed frame 11 and the clamping frame 12 are clamped onto the column, the anchors 15 on the fixed frame 11 and the clamping frame 12 are respectively inserted into the corresponding slots opened on the column, thereby increasing the stability of the fixed frame 11 and the clamping frame 12 after they are clamped onto the column.

[0043] Reference Figure 3 The second fixing component is provided in multiple ways and corresponds one-to-one with the pull rod 3. The second fixing component includes a connecting frame 16, a screw sleeve 17 and a fixing member 18. A slider 161 is fixedly provided on the connecting frame 16. A groove 19 is provided on the reinforcing frame 1. The slider 161 is slidably provided in the groove 19. The screw sleeve 17 is rotatably provided on the connecting frame 16.

[0044] Reference Figure 4 , 5The pull rod 3 has an external thread on the side wall away from the pressure plate 31 that is compatible with the screw sleeve 17. The fixing member 18 includes a limiting screw rod, which is rotatably mounted on the reinforcing frame 1. One end of the limiting screw rod passes through the slide groove 19. The length direction of the limiting screw rod is parallel to the sliding direction of the slider 161, and the limiting screw rod and the slider 161 are threaded together. One end of the pull rod 3 that passes through the wall passes through the screw sleeve 17. Then, the screw sleeve 17 and the limiting screw rod are rotated simultaneously to put the screw sleeve 17 on the pull rod 3. At the same time, the connecting frame 16 slides on the reinforcing frame 1, thereby fixing the pull rod 3 to the reinforcing frame 1. The screw sleeve 17 and the limiting screw rod need to be rotated simultaneously to allow the pull rod 3 to slide relative to the reinforcing frame 1, which can effectively prevent the connection between the pull rod 3 and the screw sleeve 17 from loosening.

[0045] Reference Figure 5 The tie rod 3 has a grouting cavity 32 inside. The end of the tie rod 3 away from the pressure plate 31 has a grouting port 33 that communicates with the grouting cavity 32. The side wall of the tie rod 3 also has several grout outlet holes 34 that communicate with the grouting cavity 32. After the wall is reinforced, sealing mortar is injected into the grouting cavity 32 of the tie rod 3 through the grouting port 33. The sealing mortar flows out through the grout outlet holes 34 to seal the gap between the wall and the tie rod 3, ensuring the heat insulation and sealing performance of the wall.

[0046] Reference Figure 5 It also includes a first sealing ring 35 and a second sealing ring 36 fitted onto the tie rod 3. Both the first sealing ring 35 and the second sealing ring 36 are made of rubber, and both the first sealing ring 35 and the second sealing ring 36 have cavities inside. When the stabilizer 2 is installed, the first sealing ring 35 is installed between the stabilizer 2 and the outer wall of the wall. When the tie rod 3 is installed, the tie rod 3 passes through the mounting hole 21, the first sealing ring 35, and the hole opened in the wall. Then, a second sealing ring 36 is fitted onto the end of the tie rod 3 that passes through the wall. When the screw sleeve 17 is fitted onto the tie rod 3, the stabilizing frame 2 presses the first sealing ring 35 against the outer wall of the wall, and the screw sleeve 17 presses the second sealing ring 36 against the inner wall of the wall, thereby sealing both ends of the hole in the wall. When the sealing mortar is injected into the gap between the wall and the tie rod 3, the sealing mortar is not easy to overflow from both sides of the hole in the wall, thereby increasing and improving the sealing effect of the hole.

[0047] The implementation principle of the external wall reinforcement structure for industrial building renovation in Embodiment 1 of this application is as follows: The installation position of the stabilizing frame 2 is marked on the outer wall of the wall, and a pre-embedded groove is opened on the outer wall. Based on the positions of the mounting holes 21 on the stabilizing frame 2, corresponding holes are opened in the wall. During installation, the stabilizing frame 2 is installed on the outer side of the wall and embedded into the pre-embedded groove on the outer wall. Each mounting hole 21 on the stabilizing frame 2 corresponds one-to-one with the hole opened on the wall. The first sealing ring 35 is set between the two, and the stabilizing frame 2 is pre-fixed. The reinforcing frame 1 is installed on the inner side of the wall, and the position of the reinforcing frame 1 is adjusted so that the fixing frame 11 and the clamping frame 12 are clamped on the column inside the wall. The tie rod 14 is installed between the fixing frame 11 and the clamping frame 12, so that the two ends of the tie rod 14 pass through the through holes on the fixing frame 11 and the clamping frame 12 respectively, and nuts are threaded to the two ends of the tie rod 14 respectively. The nuts are tightened to fix the reinforcing frame 1 to the column inside the wall.

[0048] Pull rods 3 are inserted into the mounting holes 21 on the stabilizing frame 2, passing through the first sealing ring 35 and the corresponding holes in the wall. The pressure plate 31 on the pull rod 3 abuts against the side wall of the stabilizing frame 2 away from the wall. Then, the second sealing ring 36 is fitted onto the end of the pull rod 3 that passes through the wall, and the end of the pull rod 3 that passes through the wall is inserted into the threaded sleeve 17. Then, the threaded sleeve 17 and the limiting screw are rotated simultaneously to fit the threaded sleeve 17 onto the pull rod 3. At the same time, the connecting frame 16 slides on the reinforcing frame 1. The tie rod 3 is fixed to the reinforcement frame 1 to complete the reinforcement of the exterior wall of the industrial building. Finally, sealing mortar is injected into the grouting cavity 32 of the tie rod 3 through the grouting port 33. The sealing mortar flows out through the grout outlet 34 to seal the gap between the wall and the tie rod 3. Cement mortar is injected into the pre-embedded groove on the outside of the wall and the stabilizing frame 2 is pre-embedded in the pre-embedded groove. The reinforcement frame 1, the stabilizing frame 2 and the tie rod 3 strengthen the connection between the wall and the column of the industrial building, thereby greatly improving the seismic performance of the wall after the industrial building is renovated.

[0049] This application also discloses a construction method for reinforcing the exterior walls of an industrial building, including the following steps:

[0050] S1. Wall opening: Mark the installation position of the stabilizing frame 2 on the outer side of the wall and open a pre-embedded groove on the outer side of the wall. According to the position of each mounting hole 21 on the stabilizing frame 2, open the corresponding position in the wall.

[0051] S2. Installation of the stabilizing frame 2: Install the stabilizing frame 2 on the outside of the wall and embed the stabilizing frame 2 into the pre-embedded groove opened on the outside of the wall. Each mounting hole 21 on the stabilizing frame 2 corresponds to the hole opened on the wall. Set the first sealing ring 35 between the stabilizing frame 2 and the outer wall of the wall and pre-fix the stabilizing frame 2.

[0052] S3. Installation of reinforcement frame 1: Install reinforcement frame 1 on the inside of the wall and adjust the position of reinforcement frame 1 so that the fixing frame 11 and clamping frame 12 are clamped on the column inside the wall. Install tie rod 14 between fixing frame 11 and clamping frame 12 so that both ends of tie rod 14 pass through the through holes on fixing frame 11 and clamping frame 12 respectively. Thread nuts to both ends of tie rod 14 and tighten the nuts to fix reinforcement frame 1 to the column inside the wall.

[0053] S4. Install the tie rod 3. Insert the tie rod 3 into each of the mounting holes 21 on the stabilizing frame 2. The tie rod 3 passes through the first sealing ring 35 and the corresponding hole opened on the wall. The pressure plate 31 on the tie rod 3 is pressed against the side wall of the stabilizing frame 2 away from the wall. Then, the second sealing ring 36 is fitted on the end of the tie rod 3 that passes through the wall, and the end of the tie rod 3 that passes through the wall is inserted into the threaded sleeve 17. Then, rotate the threaded sleeve 17 and the limiting screw at the same time to fit the threaded sleeve 17 onto the tie rod 3. At the same time, the connecting frame 16 slides on the reinforcing frame 1, thereby fixing the tie rod 3 to the reinforcing frame 1, thus completing the reinforcement of the exterior wall of the industrial building.

[0054] S5. Sealing treatment: seal mortar is injected into the grouting cavity 32 of the tie rod 3 through the grouting port 33. The seal mortar flows out through the grout outlet 34 to seal the gap between the wall and the tie rod 3. Cement mortar is injected into the pre-embedded groove on the outside of the wall to pre-embed the stabilizing frame 2 in the pre-embedded groove.

[0055] Example 2

[0056] Reference Figure 6 The difference from Embodiment 1 is that, during installation, the stabilizing frame 2 does not need to be pre-embedded in the outer side of the wall. The stabilizing frame 2 directly abuts against the outer side of the wall. After the building wall is reinforced, the curtain wall 4 is set on the outer side of the wall, and the stabilizing frame 2 serves as the supporting frame of the curtain wall 4. By setting the curtain wall 4 on the stabilizing frame 2, the stabilizing frame 2 can be shielded, and the aesthetics of the wall after reinforcement can be guaranteed.

[0057] 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.
