Description

Technical Field

[0001] This invention relates to the field of precast reinforced concrete wall assembly technology, specifically to a precast reinforced concrete wall connector anti-displacement structure. Background Technology

[0002] Steel plates are pre-embedded at the top and bottom of the precast reinforced concrete wall. During on-site assembly, the steel plates pre-embedded at the bottom of the precast reinforced concrete wall are welded together with the steel plates pre-embedded at the top of the next layer of precast reinforced concrete wall. During assembly, an anti-displacement structure is required to ensure that the walls can be precisely aligned.

[0003] Steel plates are pre-embedded at the top and bottom of the precast reinforced concrete wall, and anti-deviation structures are set up. During on-site assembly, the vertical steel plate pre-embedded at the bottom of the precast reinforced concrete wall is welded to the horizontal plate of the deviation correction device pre-embedded at the top of the next layer of precast reinforced concrete wall, which effectively avoids the deviation phenomenon that is prone to occur with the currently used steel sleeve connectors. The horizontal plate of the precast reinforced concrete wall pre-embedded at the top has a hole in the middle to form a notch to strengthen the grouting connection quality of the upper and lower precast walls. The concrete surface at the joint of the precast reinforced concrete wall is roughened, and the joint is filled with special grout to ensure that the upper and lower precast reinforced concrete walls are completely connected as one. The grouting at the joint serves as a reserve of the load-bearing capacity at the joint, making the load-bearing capacity at the joint greater than that of the precast reinforced concrete wall itself, realizing the seismic resistance concept of strong nodes, effectively solving the seismic resistance concept of strong shear and weak bending, strong nodes and weak components. Prefabricated buildings adopt the factory prefabrication of components and on-site assembly, which improves labor productivity, reduces labor intensity, improves component accuracy and project quality, reduces construction waste and dust emissions, and is green and environmentally friendly.

[0004] The existing precast reinforced concrete wall connections use steel sleeve connections. The anti-displacement structure is difficult to correct the deviation of the connectors during the hoisting of the precast wall, which complicates the hoisting and alignment work in high-altitude and blind areas. It requires repeated adjustments, which affects the construction speed and alignment success rate, increases the probability of connector deviation, affects the rapid and accurate placement of the wall, and leaves hidden construction quality problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an anti-displacement structure for precast reinforced concrete wall connectors, solving the problem of difficulty in correcting the misalignment of connectors during the hoisting of precast walls.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a precast reinforced concrete wall connector anti-deviation structure, comprising a first precast reinforced concrete wall, wherein multiple sets of lower connecting double-sided vertical steel plates are installed at the bottom of the first precast reinforced concrete wall, and multiple through-anchor steel bars are installed between the lower connecting double-sided vertical steel plates; a second precast reinforced concrete wall is installed below the first precast reinforced concrete wall; multiple sets of correction devices are installed at the top of the second precast reinforced concrete wall; a floor slab is installed on the second precast reinforced concrete wall; the correction device includes a limiting horizontal plate, an assembly groove is provided on the limiting horizontal plate, a vertical plate is installed on the bottom side of the limiting horizontal plate, multiple connecting anchor rods are connected to the bottom side of the limiting horizontal plate, and a limiting edge line is provided on the upper surface of the limiting horizontal plate.

[0007] The above technical solution involves hoisting the first precast reinforced concrete wall and pushing it so that the sidewalls of the two vertical steel plates connected to its bottom are vertical and close to the limiting edge line until they are aligned. This achieves alignment of the central axes of the upper and lower walls. After placement, welding is performed immediately to lock the wall's degrees of freedom in all directions. The alignment device provides physical limits, simplifying high-altitude and blind-zone alignment operations, reducing shaking and repeated adjustments, effectively improving the alignment success rate and construction speed, effectively solving the problem of wall fixation, reducing the shaking of the first precast reinforced concrete wall, ensuring construction safety, effectively reducing the probability of deviation caused by operational errors, ensuring that the wall can be accurately positioned, and avoiding potential construction quality hazards.

[0008] Preferably, the limiting horizontal plate corresponds to the position of multiple sets of lower connecting double-sided vertical steel plates at the bottom of the first precast reinforced concrete wall, and the dimensions are reserved with welding construction error allowance. A welded seam is provided between the lower connecting double-sided vertical steel plates of the first precast reinforced concrete wall and the correction device.

[0009] The above technical solution allows for a certain gap between the vertical steel plates on both sides and the limiting horizontal plate, preventing the device from failing to be positioned due to hard collisions. At the same time, the reserved gap serves as a welding seam, providing a clear working space for the welding torch and a place to accommodate the deposited metal, ensuring a full weld and controllable quality. It also avoids direct damage to the corrector body or concrete edge from the high temperature of welding. While ensuring accuracy, it provides space for error tolerance and rapid fixation, which is conducive to improving the connection quality.

[0010] Preferably, multiple connecting anchor rods are installed on the limiting horizontal plate, and the connecting anchor rods are anchored into the second precast reinforced concrete wall.

[0011] The above technical solution ensures that the limiting horizontal plate is accurately positioned and fixed by the connecting anchor rods on the limiting horizontal plate, thus enabling the limiting horizontal plate to perform its limiting and fixing functions and achieving reliable connection with the precast wall, which helps to improve the reliability of the connection.

[0012] Preferably, a vertical plate is installed on the bottom side of the limiting horizontal plate, and the vertical plate is anchored into the floor slab.

[0013] The above technical solution, by using the vertical plate on the bottom side of the limiting horizontal plate to form a shear key, improves the shear resistance of the first precast reinforced concrete wall connection, which is conducive to ensuring the shear bearing capacity requirements of the first precast reinforced concrete wall connection.

[0014] Preferably, the limiting cross plate is provided with an assembly groove, and the assembly groove is filled with special grouting material.

[0015] The above technical solution involves filling the assembly groove with special grouting material, which completely connects the upper and lower precast reinforced concrete walls into one unit. This serves as a reserve of load-bearing capacity at the connection point, realizing the seismic resistance concept of strong node connection and improving the connection quality.

[0016] Preferably, multiple sets of guide devices are installed at the top of the first precast reinforced concrete wall, multiple side wall steel bars are installed on the side wall of the first precast reinforced concrete wall, two sets of lifting rings are installed at the top of the first precast reinforced concrete wall by means of lifting nails, and multiple upper steel bars are installed on the top side of the first precast reinforced concrete wall.

[0017] The above technical solution involves using lifting rings to hoist the first precast reinforced concrete wall. After hoisting, the lifting nails on the lifting rings are unscrewed from the wall, thereby enabling the disassembly and reuse of the lifting rings and improving their reusability.

[0018] Preferably, the bottom end of the second precast reinforced concrete wall is equipped with multiple lower connecting double-sided vertical steel plates, and multiple through anchoring steel bars are installed between the lower connecting double-sided vertical steel plates. Multiple upper steel bars are installed on the top side of the second precast reinforced concrete wall. Two sets of lifting rings are installed on the top of the second precast reinforced concrete wall by means of lifting nails. Multiple sets of correction devices are installed on the top of the second precast reinforced concrete wall. Multiple side wall steel bars are installed on the side walls of the lower connecting double-sided vertical steel plates.

[0019] Through the above technical solution: the second precast reinforced concrete wall serves as the next layer of wall, and the lifting rings on it are detachable and reusable. After the floor slab is poured, the upper reinforcing bars and the correction device on the second precast reinforced concrete wall realize the fixed connection between the floor slab and the second precast reinforced concrete wall, which is conducive to improving the firmness of the connection between the floor slab and the second precast reinforced concrete wall.

[0020] Preferably, the lower connecting double-sided vertical steel plates on the first precast reinforced concrete wall and the guide device on the second precast reinforced concrete wall are welded together.

[0021] Through the above technical solution: the alignment device is responsible for preventing deviation during the construction and installation stage, ensuring that the wall is in the correct position before it is placed. It adopts an electric welding structure and is responsible for preventing deviation during the use stage. After the wall is placed and aligned, it guides the installation, welds and locks the degrees of freedom in all directions, and bears shear force, ensuring that the precast wall does not deviate or slip during long-term use, effectively improving the stability of the precast wall and reliably transmitting the effects of various loads.

[0022] A preferred method for preventing misalignment of precast reinforced concrete wall connectors includes the following steps: S1. The guide device is pre-embedded and fixed on the second precast reinforced concrete wall, and the limiting edge line of the limiting plate on the guide device is aligned with one side edge of the second precast reinforced concrete wall. S2. Hoist the first precast reinforced concrete wall and push the first precast reinforced concrete wall so that the side walls of the vertical steel plates connected to the lower sides are perpendicular to the limiting horizontal plate, and make the side walls of the vertical steel plates connected to the lower sides close to the limiting edge line of the limiting horizontal plate. S3. Continue to lower and move the first precast reinforced concrete wall so that the side walls of the vertical steel plates on both sides are aligned with the limiting edge of the limiting horizontal plate, and then weld and fix it in time. S4. After construction is completed, the two sets of lifting rings on the top side of the first precast reinforced concrete wall are disassembled and reused.

[0023] The above technical solution involves: pushing the hoisted first precast reinforced concrete wall to make the sidewalls of the lower connecting vertical steel plates perpendicular to the limiting horizontal plate, and gradually moving them closer to the limiting edge line of the limiting horizontal plate, thus aligning the sidewalls of the lower connecting vertical steel plates with the limiting edge line, achieving alignment of the central axes of the first and second precast reinforced concrete walls; before the hoisted first precast reinforced concrete wall falls and engages with the second precast reinforced concrete wall, the movement of the first precast reinforced concrete wall is limited by the alignment device, and the operator only needs to control the position of the first precast reinforced concrete wall to ensure that the lower connecting vertical steel plates are perpendicular to the limiting horizontal plate. The edge of the vertical steel plate is aligned with the limiting edge of the limiting horizontal plate of the guide device for the second precast reinforced concrete wall, thus achieving the splicing of the first precast reinforced concrete wall and the second precast reinforced concrete wall on the next floor. After the first precast reinforced concrete wall is hoisted and positioned, the weld joint is promptly welded and fixed. The horizontal and vertical degrees of freedom of the first precast reinforced concrete wall are locked. The guide device's auxiliary limiting makes operation and control simple and clear for workers, significantly simplifying high-altitude and blind-zone alignment work, improving speed, accuracy and safety, and completing the permanent connection. The guide device completes its temporary anti-deviation mission. After construction is completed, the two sets of lifting rings on the top side of the first precast reinforced concrete wall are disassembled for reuse.

[0024] This invention provides an anti-displacement structure for precast reinforced concrete wall connectors. It has the following beneficial effects: 1. This invention simplifies the hoisting and alignment work in high-altitude and blind areas by limiting the movement of the first precast reinforced concrete wall with a guide device, reduces repeated adjustments, effectively improves the alignment success rate and construction speed, effectively reduces the shaking of the first precast reinforced concrete wall, effectively improves safety, effectively reduces the probability of deviation caused by operational errors, ensures that the wall can be accurately positioned, and avoids leaving hidden construction quality problems.

[0025] 2. This invention uses a correction device to prevent misalignment during the construction and installation phase, ensuring the wall is correctly positioned before placement. It employs electric welding to prevent misalignment during the usage phase. After the wall is aligned in place, it guides the installation, locks the structural degrees of freedom, and withstands shear forces, ensuring that the precast wall does not misalign or slip during long-term use. This improves the stability of the precast wall and reliably transmits various loads. Attached Figure Description

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides a precast reinforced concrete wall connector anti-deviation structure, including a first precast reinforced concrete wall 1. Multiple sets of lower connecting vertical steel plates 2 are installed at the bottom of the first precast reinforced concrete wall 1. Multiple through-anchor steel bars 3 are installed between the lower connecting vertical steel plates 2. A second precast reinforced concrete wall 13 is installed below the first precast reinforced concrete wall 1. Multiple sets of deviation correctors 5 are installed at the top of the second precast reinforced concrete wall 13. A floor slab 14 is installed on the second precast reinforced concrete wall 13. The deviation corrector 5 includes a limiting horizontal plate 6, an assembly groove 7 is provided on the limiting horizontal plate 6, a vertical plate 8 is installed on the bottom side of the limiting horizontal plate 6, multiple connecting anchor rods 9 are connected to the bottom side of the limiting horizontal plate 6, and a limiting edge line 10 is provided on the upper surface of the limiting horizontal plate 6.

[0030] Specifically, when splicing the first precast reinforced concrete wall 1 with the second precast reinforced concrete wall 13 on the next floor on site, the first precast reinforced concrete wall 1 is hoisted into the air. Multiple workers position the first precast reinforced concrete wall 1 so that its lower surface is aligned with the central axis of the second precast reinforced concrete wall 13. Before this, the connecting anchor rod 9 on the guide device 5 is inserted into the second precast reinforced concrete wall 13, and the limiting horizontal plate 6 on the guide device 5 needs to be perpendicular to the second precast reinforced concrete wall 13, and the limiting edge line 10 of the limiting horizontal plate 6 on the guide device 5 needs to be aligned with one side edge of the second precast reinforced concrete wall 13. The floor slab 14 is connected by the upper steel... After the reinforcing bar 11 is installed on the second precast reinforced concrete wall 13, the guide device 5 embedded in the second precast reinforced concrete wall 13 is located inside the floor slab 14, but the limiting horizontal plate 6 on it is exposed; by pushing the hoisted first precast reinforced concrete wall 1, the side wall of the lower connecting double vertical steel plate 2 of the first precast reinforced concrete wall 1 is made perpendicular to the limiting horizontal plate 6, and the side wall of the lower connecting double vertical steel plate 2 is brought closer to the limiting edge line 10 of the limiting horizontal plate 6, and gradually moved to align the side wall of the lower connecting double vertical steel plate 2 with the limiting edge line 10, so as to achieve the alignment of the central axis of the first precast reinforced concrete wall 1 and the second precast reinforced concrete wall 13; in the hoisted first precast reinforced concrete wall Before the first precast reinforced concrete wall 1 is lowered and engaged with the second precast reinforced concrete wall 13, the movement of the first precast reinforced concrete wall 1 is limited by the alignment device. The operator only needs to control the position of the first precast reinforced concrete wall 1 so that the edge of the vertical steel plate 2 connecting the two sides is aligned with the limiting edge line 10 of the limiting horizontal plate 6 of the alignment device of the second precast reinforced concrete wall 13, thus achieving the splicing of the first precast reinforced concrete wall 1 with the second precast reinforced concrete wall 13 on the next floor. After the first precast reinforced concrete wall 1 is hoisted and aligned, the weld joint 15 is welded and fixed in time. The degrees of freedom of the first precast reinforced concrete wall 1 in the horizontal and vertical directions are locked. The alignment device 5 assists in limiting the movement of the first precast reinforced concrete wall 1, allowing the operator to... The operator's operation and control are simple and clear, effectively simplifying the hoisting and alignment work in high-altitude and blind spots, effectively improving the alignment success rate and construction speed, reducing repeated adjustments, and effectively improving construction efficiency and accuracy. The swaying of the first precast reinforced concrete wall 1 during hoisting is dangerous, and the correction device 5 provides a stable physical support. The connection between the first precast reinforced concrete wall 1 and the second precast reinforced concrete wall 13 is welded, which effectively reduces the swaying of the first precast reinforced concrete wall 1, ensures effective connection and force transmission between the upper and lower structures, reduces the risk of workers being injured or components going out of control, effectively improves safety, ensures structural reliability, and lays the foundation for subsequent permanent connection, with a clear and important anti-deviation function.

[0031] Please see the appendix Figure 4 - Appendix Figure 7The limiting horizontal plate 6 corresponds to the position of the multiple sets of lower connecting double-sided vertical steel plates 2 at the bottom of the first precast reinforced concrete wall 1, and the size is left with welding construction error margin. A welded seam 15 is provided between the lower connecting double-sided vertical steel plates 2 of the first precast reinforced concrete wall 1 and the correction device 5.

[0032] Specifically, during the factory production and on-site hoisting of precast walls, dimensional deviations are inevitable. The reserved allowance allows for a certain gap between the connecting vertical steel plates 2 on both sides and the limiting horizontal plate 6 to avoid the inability to be positioned due to hard collision. At the same time, the reserved gap serves as the welding seam 15, providing a clear working space for the welding gun and a place to accommodate the deposited metal, ensuring full welding and controllable quality. It also avoids direct damage to the body of the correction device 5 or the concrete edge due to the high temperature of welding, providing space for error tolerance and rapid fixation while ensuring accuracy.

[0033] Please see the appendix Figure 5 - Appendix Figure 6 Multiple connecting anchor rods 9 are installed on the limiting horizontal plate 6, and the connecting anchor rods 9 are anchored into the second precast reinforced concrete wall 13.

[0034] Specifically, the connecting anchor rods 9 on the limiting horizontal plate 6 ensure that the limiting horizontal plate 6 is accurately positioned and fixed, so that the limiting horizontal plate 6 plays a limiting and fixing role and achieves a reliable connection with the precast wall.

[0035] Please see the appendix Figure 7 A vertical plate 8 is installed on the bottom side of the limiting horizontal plate 6, and the vertical plate 8 is anchored into the floor slab 14.

[0036] Specifically, by limiting the vertical plate 8 on the bottom side of the horizontal plate 6, a shear key is formed, which improves the shear resistance of the first precast reinforced concrete wall 1 connection and ensures the shear bearing capacity requirement of the first precast reinforced concrete wall 1 connection.

[0037] Please see the appendix Figure 5 - Appendix Figure 6 An assembly groove 7 is provided on the limiting horizontal plate 6, and the assembly groove 7 is filled with special grouting material.

[0038] Specifically, by filling the assembly groove 7 with special grouting material, the upper and lower precast reinforced concrete walls are completely connected as a whole, which serves as a reserve of load-bearing capacity at the connection and realizes the seismic resistance concept of strong node connection.

[0040] Specifically, the first precast reinforced concrete wall 1 is hoisted using the lifting ring 12. After hoisting, the lifting nails on the lifting ring 12 are unscrewed from the wall, thereby enabling the disassembly and reuse of the lifting ring 12.

[0041] Please see the appendix Figure 3 The bottom of the second precast reinforced concrete wall 13 is equipped with multiple lower connecting vertical steel plates 2, and multiple through anchoring steel bars 3 are installed between the lower connecting vertical steel plates 2. Multiple upper steel bars 11 are installed on the top side of the second precast reinforced concrete wall 13. Two sets of lifting rings 12 are installed on the top of the second precast reinforced concrete wall 13 by means of lifting nails. Multiple sets of correction devices 5 are installed on the top of the second precast reinforced concrete wall 13. Multiple side wall steel bars 4 are installed on the side wall of the lower connecting vertical steel plates 2.

[0042] Specifically, the second precast reinforced concrete wall 13 serves as the next layer of wall, and the lifting ring 12 on it is detachable and reusable. The upper steel bar 11 and the correction device 5 on the second precast reinforced concrete wall 13 are fixedly connected to the floor slab 14 and the second precast reinforced concrete wall 13 after the floor slab 14 is poured.

[0043] Please see the appendix Figure 7 The lower connecting double-sided vertical steel plates 2 on the first precast reinforced concrete wall 1 and the guide device 5 on the second precast reinforced concrete wall 13 are welded together.

[0044] Specifically, the alignment device 5 is responsible for preventing misalignment during the construction and installation phase, ensuring that the wall is in the correct position before it is placed. It adopts an electric welding structure and is responsible for preventing misalignment during the use phase. After the wall is aligned, it guides the installation, welds and locks the degrees of freedom in all directions, and bears shear force, ensuring that the precast wall does not deviate or slip during long-term use, effectively improving the stability of the precast wall and reliably transmitting the effects of various loads.

[0045] Please see the appendix Figure 1 - Appendix Figure 7 The method for preventing misalignment of precast reinforced concrete wall connectors includes the following steps: S1. The guide device 5 is pre-embedded and fixed on the second precast reinforced concrete wall 13, and the limiting edge line 10 of the limiting horizontal plate 6 on the guide device 5 is aligned with one side edge of the second precast reinforced concrete wall 13. S2. Hoist the first precast reinforced concrete wall 1, push the first precast reinforced concrete wall 1 so that the side wall of the lower connecting double vertical steel plates 2 is perpendicular to the limiting horizontal plate 6, and make the side wall of the lower connecting double vertical steel plates 2 close to the limiting edge line 10 of the limiting horizontal plate 6. S3. Continue to lower and move the first precast reinforced concrete wall 1 so that the side wall of the vertical steel plate 2 connected to the lower side is aligned with the limiting edge line 10 of the limiting horizontal plate 6, and then weld it in time. S4. After construction is completed, the two sets of lifting rings 12 on the top side of the first precast reinforced concrete wall 1 are disassembled and reused.

[0046] Specifically, by pushing the hoisted first precast reinforced concrete wall 1, the sidewalls of the lower connecting vertical steel plates 2 of the first precast reinforced concrete wall 1 are made perpendicular to the limiting horizontal plate 6, and the sidewalls of the lower connecting vertical steel plates 2 are brought closer to the limiting edge line 10 of the limiting horizontal plate 6. Gradually, the sidewalls of the lower connecting vertical steel plates 2 are aligned with the limiting edge line 10, thus aligning the central axes of the first precast reinforced concrete wall 1 and the second precast reinforced concrete wall 13. Before the hoisted first precast reinforced concrete wall 1 falls and engages with the second precast reinforced concrete wall 13, the movement of the first precast reinforced concrete wall 1 is limited by the guide device 5. The operator only needs to control the position of the first precast reinforced concrete wall 1, ensuring that the sidewalls of the lower connecting vertical steel plates 2 are perpendicular to the limiting horizontal plate 6. The edge of the vertical steel plate 2 is aligned with the limiting edge line 10 of the limiting horizontal plate 6 of the guide device 5 of the second precast reinforced concrete wall 13, so as to realize the splicing of the first precast reinforced concrete wall 1 and the second precast reinforced concrete wall 13 of the next layer. After the first precast reinforced concrete wall 1 is hoisted and positioned and aligned, the weld seam 15 is welded and fixed in time. The horizontal and vertical degrees of freedom of the first precast reinforced concrete wall 1 are locked. The guide device 5 assists in limiting the position, making the operation and control of the operator simple and clear, significantly simplifying the high-altitude and blind-zone alignment work, improving speed, accuracy and safety, and completing the permanent connection. The guide device 5 completes the temporary anti-deviation mission. After the construction is completed, the two sets of lifting rings on the top side of the first precast reinforced concrete wall 1 are disassembled and reused.
