Technical Field
[0001] This invention belongs to the field of building construction technology, specifically relating to a precast wall installation and positioning device and method. Background Technology
[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction is transferred to factories for prefabrication. Various components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) required for the building are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.
[0003] Currently, precast walls on the first floor need to be installed on cast-in-place shear walls. In the construction of prefabricated building structures, such as in https: / / www.bilibili.com / video / BV1aV4y1271E / , during the assembly of precast walls, the position of the reserved reinforcing bars needs to be pre-adjusted. During the hoisting of the precast walls, construction workers need to use a reflector to observe the position of the reserved reinforcing bars and grouting cylinders, and then adjust and align them, as well as temporarily fix the precast walls. Because construction workers cannot directly observe the position of the grouting cylinders and reserved reinforcing bars, multiple adjustments and confirmations are often required when adjusting the position of the precast walls or reserved reinforcing bars, which prolongs the assembly time of the precast walls and reduces construction efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide a precast wall installation and positioning device and method, which aims to solve the problem mentioned in the background art that construction personnel cannot directly observe the position of the grouting cylinder and the reserved steel bars. When adjusting the position of the precast wall or the reserved steel bars, multiple adjustments and confirmations are often required, which prolongs the assembly time of the precast wall and reduces the construction efficiency.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A precast wall installation and positioning device includes a cast-in-place wall and a precast wall, wherein the cast-in-place wall is movably connected to a male positioning component, and the precast wall is movably connected to a female positioning component, wherein the male positioning component and the female positioning component are adapted to each other. The male positioning component includes an adjusting seat, which is provided with a plurality of fastening units. Each fastening unit is spaced apart along the length of the adjusting seat. One fastening unit is fixedly connected to the adjusting seat, and the other fastening units are slidably connected to the adjusting seat. Each fastening unit is detachably connected to the reserved reinforcing bars of the corresponding cast-in-place wall. The end of the fastening unit away from the cast-in-place wall is provided with directional reinforcing bars that are vertically upward. The directional reinforcing bars correspond one-to-one with the reserved reinforcing bars. The adjusting seat is vertically provided with a sliding hole, and a sliding rod is provided in the sliding hole. The diameter of the sliding hole is larger than the diameter of the sliding rod. One end of the sliding rod is rotatably connected to a universal wheel, and the other end of the sliding rod is provided with a cover. A compression spring is provided between the cover and the adjusting seat, and the compression spring is sleeved on the sliding rod. The female positioning component includes an "L"-shaped positioning plate, which is detachably connected to the precast wall. The vertical plate of the "L"-shaped positioning plate has several connecting holes, each corresponding to a grout outlet hole of the precast wall. The horizontal plate of the "L"-shaped positioning plate has several positioning holes, each corresponding to a grouting sleeve of the precast wall.
[0006] Furthermore, the fastening unit includes a first fastening rod, a second fastening rod, a wedge-shaped locking block, a sliding frame, a wedge-shaped driving block fastening seat, and a threaded post. The second fastening rod is slidably connected to the first fastening rod. The wedge-shaped locking block is provided between the second fastening rod and the first fastening rod. One end of the wedge-shaped locking block is fixedly connected to the sliding frame. The sliding frame is sleeved on the outside of the first fastening rod. The end of the sliding frame away from the wedge-shaped locking block is provided with the first wedge-shaped driving block. The first wedge-shaped driving block is threadedly connected to the threaded post. One end of the threaded post is rotatably connected to the first fastening rod. The threaded post rotates clockwise or counterclockwise to drive the first wedge-shaped driving block closer to or away from the sliding frame. The first fastening rod is provided with the fastening seat, and the fastening seat is connected to the directional reinforcing bar. The end of the first fastening rod away from the wedge-shaped locking block is provided with a first slot, and the end of the second fastening rod away from the wedge-shaped locking block is provided with a second slot. The first slot and the second slot are used to clamp the reserved reinforcing bar.
[0007] Furthermore, the threaded column is threadedly connected to the second wedge-shaped drive block. The threaded column rotates clockwise or counterclockwise to drive the second wedge-shaped drive block away from or closer to the sliding frame. The second wedge-shaped drive block and the first wedge-shaped drive block are located on opposite sides of the sliding frame.
[0008] Furthermore, the threaded post is provided with a hand rudder, and the first and second slots are respectively provided with gaskets, which are rubber gaskets.
[0009] Furthermore, the adjusting seat is provided with sliding grooves on both sides, and the sliding grooves are adapted to the fastening rod.
[0010] Furthermore, the horizontal plate of the "L"-shaped positioning plate is provided with several adjustment grooves, each of which is spaced apart along the length of the "L"-shaped positioning plate. Each adjustment groove is provided with a positioning block, and the positioning block is provided with a positioning hole that is adapted to the directional reinforcement. The positioning block is rotatably connected to an adjustment rod, and the adjustment rod is threadedly connected to the "L"-shaped positioning plate. The adjustment rod can be rotated clockwise or counterclockwise to drive the positioning block to slide back and forth along the adjustment groove.
[0011] Furthermore, the grouting sleeve of the precast wall is equipped with a rubber column, one end of which is located inside the grouting sleeve, and the other end of which protrudes through the grout outlet. The rubber column is equipped with an air inlet, which is movably connected to an adjustment mechanism.
[0012] Furthermore, the cast-in-place wall is provided with several protective seats, each corresponding to a reserved reinforcing bar. The protective seat is detachably connected to a protective sleeve. When the protective sleeve is in the working position, the reserved reinforcing bar is located inside the protective sleeve. The protective seat is detachably connected to an adjustment mechanism.
[0013] A method for positioning and installing precast walls, utilizing precast wall positioning and installation equipment, includes the following steps: Step 1: The operator positions the adjusting seat on one side of the reserved reinforcing bar and moves the directional reinforcing bar away from the reserved reinforcing bar; Step 2: Connect the fastening unit fixedly connected to the adjusting seat to the corresponding reserved steel bar, and position the fastening unit at the upper section of the reserved steel bar; Step 3: Connect the fastening unit that is slidably connected to the adjusting seat to the corresponding reserved steel bar, and position the fastening unit at the upper section of the reserved steel bar; Step 4: Connect the "L"-shaped positioning plate to the precast wall, and position the "L"-shaped positioning plate and the directional reinforcement on the same side of the precast wall; Step 5: Use lifting equipment to hoist the precast wall to the construction floor and slowly lower the precast wall. When the precast wall is 1.5 meters above the floor, manually support the wall and continue to lower it until the "L"-shaped positioning plate is 1-3 centimeters away from the directional steel bar, then stop the descent of the precast wall. Step Six: The operator confirms the position of the directional reinforcement and the corresponding positioning hole. When the deviation between the directional reinforcement and the corresponding positioning hole is small, the operator adjusts the position of the precast wall or the directional reinforcement according to the deviation direction of the directional reinforcement to make the directional reinforcement and the corresponding positioning hole correspond one-to-one. When the directional reinforcement and the corresponding positioning hole correspond one-to-one, the precast wall continues to fall. The directional reinforcement is inserted into the corresponding positioning hole and the precast wall continues to fall. When the lower wall of the precast wall abuts the upper surface of the fastening unit, the reserved reinforcement is inserted into the corresponding grouting sleeve, and the falling of the precast wall stops. Step 7: Remove the "L"-shaped positioning plate from the precast wall, remove the fastening unit from the reserved steel bar, and move the adjusting seat away from the precast wall, carrying the fastening unit and the "L"-shaped positioning plate. Step 8: Continue to lower the precast wall into place on the pad, temporarily fix the precast wall, remove the lifting equipment, and perform grouting to complete the installation of the precast wall.
[0014] Furthermore, the diameter of the directional reinforcement bar is adapted to the diameter of the positioning hole.
[0015] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned structure, are as follows: The present invention provides a male positioning component for movable connection of cast-in-place walls and a female positioning component for movable connection of precast walls, wherein the male positioning component and the female positioning component are adapted to each other. The male positioning component includes an adjusting seat, which is provided with a plurality of fastening units. Each fastening unit is spaced apart along the length direction of the adjusting seat. One fastening unit is fixedly connected to the adjusting seat, and the other fastening units are slidably connected to the adjusting seat. Each fastening unit is detachably connected to the corresponding reserved steel bar of the cast-in-place wall. This arrangement can adapt to different distances between adjacent reserved steel bars, thus improving adaptability. The end of the fastening unit away from the cast-in-place wall is provided with a directional steel bar that is vertically upward. The directional steel bar corresponds one-to-one with the reserved steel bar. This arrangement of the directional steel bar is equivalent to moving the reserved steel bar parallel to the outside of the precast wall.
[0016] The adjusting seat has a vertical sliding hole with a sliding rod inside. The diameter of the sliding hole is larger than the diameter of the sliding rod. With this configuration, after the fastening unit is fastened to the reserved steel bar, the operator applies force (pressing down or raising) to the adjusting seat to make the adjusting seat move the directional steel bar for fine adjustment. One end of the sliding rod is rotatably connected to a caster wheel to facilitate the movement of the adjusting seat. The other end of the sliding rod is equipped with a cover, and a compression spring is installed between the cover and the adjusting seat. The compression spring is sleeved on the sliding rod.
[0017] The female positioning component includes an "L"-shaped positioning plate, which is detachably connected to the precast wall. The vertical plate of the "L"-shaped positioning plate has several connection holes, each corresponding to a grout outlet hole in the precast wall. This arrangement makes full use of the existing structure of the precast wall. The horizontal plate of the "L"-shaped positioning plate has several positioning holes, each corresponding to a grouting sleeve in the precast wall. This arrangement of positioning holes is equivalent to moving the grouting sleeve parallel to the outside of the precast wall.
[0018] In summary, the present invention, employing the aforementioned structure, transforms the previously unobservable alignment of the reserved reinforcing bars and grouting sleeve into a directly observable alignment of the directional reinforcing bars and positioning holes. This reduces the assembly time of the precast wall, improves construction efficiency, and solves the problem mentioned in the background art where construction personnel cannot directly observe the positions of the grouting sleeve and reserved reinforcing bars, often requiring multiple adjustments and confirmations when adjusting the position of the precast wall or reserved reinforcing bars, thus prolonging the assembly time of the precast wall and reducing construction efficiency. Furthermore, the position of the directional reinforcing bars can be fine-tuned through the adjusting seat, further reducing the assembly time of the precast wall and improving construction efficiency, making it suitable for the installation of precast walls.

Detailed Implementation
[0022] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.
[0023] This embodiment discloses a prefabricated wall installation and positioning device, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 14 , Figure 19As shown, the structure includes a cast-in-place wall 1 and a precast wall 2. The cast-in-place wall 1 is provided with multiple reserved reinforcing bars 101, and the precast wall 2 is provided with multiple grouting sleeves 201. Each grouting sleeve 201 corresponds to one of the reserved reinforcing bars 101, and the diameter of the grouting sleeve 201 is larger than the diameter of the reserved reinforcing bars 101. The cast-in-place wall 1 is movably connected to a male positioning component 3, and the precast wall 2 is movably connected to a female positioning component 4. The male positioning component 3 and the female positioning component 4 are compatible. This arrangement facilitates the disassembly and assembly of the male positioning component 3 and the female positioning component 4. The male positioning component 3 includes an adjusting seat 301. The two side walls of the adjusting seat 301 are respectively provided with slide grooves 30106 by a machine tool. The length of the slide grooves 30106 is along... The adjusting seat 301 is positioned along its length. The width of the slide groove 30106 is adapted to the thickness of the fastening rod 30201. The top and bottom of the fastening rod 30201 abut against the top and bottom of the slide groove 30106, respectively. The fastening rod 30201 slides back, forth, left, and right along the slide groove 30106. A sliding frame is provided on the top of the adjusting seat 301 via a machine tool. The sliding frame facilitates the sliding of the fastening unit 302 within the adjusting seat 301. The adjusting seat 301 has multiple fastening units 302, which are spaced apart along the length of the adjusting seat 301. The number of fastening units 302 is equal to the number of reserved reinforcing bars 101 in the cast-in-place wall 1. One of the fastening units 302 can be fixedly connected to the adjusting seat 301 by welding, or by bolts. The remaining fastening units 302 are slidably connected to the adjusting seat 301. The slidably connected fastening units 302 can adapt to different longitudinal and transverse arrangements of the reserved reinforcing bars 101, improving the adaptability of the male positioning component 3. After the slidably connected fastening units 302 are connected to the reserved reinforcing bars 101, the fastening units 302 can be connected to the adjusting seat 301 by bolts, by snap-fit, or by clip-on. Each fastening unit 302... 02 The reserved steel bars 101 of the corresponding cast-in-place wall 1 can be detachably connected. The fastening unit 302 can be connected to the reserved steel bars 101 by pipe wrench, clamp, or bolt. The end of the fastening unit 302 away from the cast-in-place wall 1 is fixedly connected to the directional steel bar 303 by welding. The diameter of the directional steel bar 303 is equal to the diameter of the reserved steel bar 101. The directional steel bar 303 is vertically connected to the fastening unit 302. The directional steel bar 303 corresponds one-to-one with the reserved steel bar 101. The directional steel bar 303 is equivalent to the reserved steel bar 101 moving outward by the same distance in parallel.The adjusting seat 301 has a vertical sliding hole 30101 formed by a machine tool. A sliding rod 30102 is installed inside the sliding hole 30101. The diameter of the sliding hole 30101 is larger than the diameter of the sliding rod 30102. One end of the sliding rod 30102 is rotatably connected to a caster wheel 30103. This arrangement facilitates the movement of the adjusting seat 301. The other end of the sliding rod 30102 is provided with a cover 30104. The cover 30104 can be connected to the sliding rod 30102 by threads or bolts. A compression spring 30105 is provided between the cover 30104 and the adjusting seat 301. The compression spring 30105 is sleeved on the sliding rod 30102. This arrangement allows the adjusting seat 301 to move slightly under external force. Adjustment is achieved by applying downward pressure to the end of the adjusting seat 301 away from the reserved reinforcing bar 101 (the downward pressure can be applied directly by the operator or by the operator with the aid of a tool). The end of the adjusting seat 301 away from the reserved reinforcing bar 101 moves downward, and the reserved reinforcing bar 101 bends outward due to its elasticity, causing the directional reinforcing bar 303 to be finely adjusted. The female positioning component 4 includes an "L"-shaped positioning plate 401, which is detachably connected to the precast wall 2. The vertical plate of the "L"-shaped positioning plate 401 is provided with multiple connecting holes 402 through a machine tool. The multiple connecting holes 402 correspond one-to-one with the grout outlet holes of the precast wall 2. One end of the bolt passes through the connecting hole 402 and is threaded to the grout outlet hole. The grout outlet hole can be composed of a metal pipe, and one end of the metal pipe is fixedly connected by welding. The grouting sleeve 201, a metal pipe with internal threads cut by a machine tool, connects the "L"-shaped positioning plate 401 to the precast wall 2. The precast wall 2 can also be connected to the "L"-shaped positioning plate 401 via a fixing plug. One end of the fixing plug passes through the connecting hole 402 and is embedded in the grout outlet hole, thus connecting the precast wall 2 to the "L"-shaped positioning plate 401. This arrangement fully utilizes the existing structure of the precast wall 2. The horizontal plate of the "L"-shaped positioning plate 401 has multiple positioning holes 403 cut by a machine tool. Each positioning hole 403 corresponds one-to-one with the grouting sleeve 201 of the precast wall 2. Each positioning hole 403 effectively moves the grouting sleeve 201 outwards by the same distance. The center distance of the movement of the positioning hole 403 is equal to the center distance of the movement of the directional reinforcement 303. The diameter of the positioning hole 403 can be equal to the diameter of the grouting sleeve 201, and the diameter of the positioning hole 403 can also be equal to the diameter of the reserved steel bar 101. Furthermore, the directional steel bar 303 corresponds one-to-one with the positioning hole 403. This arrangement transforms the previously unseen reserved steel bar 101 and grouting sleeve 201 into a directly visible directional steel bar 303 and positioning hole 403, reducing the assembly time of the precast wall 2, improving construction efficiency, and solving the problem mentioned in the background technology that construction personnel cannot directly observe the position of the grouting sleeve 201 and the reserved steel bar 101. When adjusting the position of the precast wall 2 or the reserved steel bar 101, multiple adjustments and confirmations are often required, which prolongs the assembly time of the precast wall 2 and reduces construction efficiency.In use: First, draw positioning lines on both sides of the reserved reinforcing bar 101, with the distance between the two positioning lines equal to the thickness of the precast wall 2. Then, the operator positions the adjusting seat 301 on one side of the reserved reinforcing bar 101 and moves the directional reinforcing bar 303 away from the reserved reinforcing bar 101. Next, connect the fastening unit 302, which is fixedly connected to the adjusting seat 301, to the corresponding reserved reinforcing bar 101, and position the fastening unit 302 at the upper section of the reserved reinforcing bar 101. This arrangement avoids differences between the upper and lower parts due to bending of the reserved reinforcing bar 101. Then, connect the fastening unit 302, which is slidably connected to the adjusting seat 301, to the corresponding reserved reinforcing bars 101, and position the fastening unit 302 at the upper section of the reserved reinforcing bar 101. This arrangement of the directional reinforcing bar 303... Step 03 is equivalent to moving the reserved reinforcing bar 101 parallel to the outside of the precast wall 2. Then, the "L"-shaped positioning plate 401 is connected to the precast wall 2, and the "L"-shaped positioning plate 401 and the directional reinforcing bar 303 are located on the same side of the precast wall 2. This setup is equivalent to moving the grouting sleeve 201 parallel to the outside of the precast wall 2. The diameter of the positioning hole 403 can be equal to the diameter of the grouting sleeve 201, and the diameter of the positioning hole 403 can also be equal to the diameter of the directional reinforcing bar 303. Afterwards, the precast wall 2 is hoisted to the construction floor using lifting equipment and slowly lowered. When the precast wall 2 reaches a height of 1.5 meters from the floor level, it is manually supported, and the precast wall 2 continues to fall until the "L"-shaped positioning plate 401 is close to the directional reinforcing bar 303. Stop the descent of precast wall 2 at a distance of 1-3 cm. After manual support, adjust the position of precast wall 2 as it falls, ensuring that both sides of precast wall 2 correspond to the positioning lines on both sides of the reserved reinforcing bars 101. Then, confirm the position of the directional reinforcing bars 303 and their corresponding positioning holes 403. If the misalignment of the directional reinforcing bars 303 and their corresponding positioning holes 403 is significant, the precast wall 2 should be lifted back to a height of 1.5 meters from the floor level and lowered again for repositioning. If the misalignment of the directional reinforcing bars 303 and their corresponding positioning holes 403 is minor, the operator should adjust the position according to the directional reinforcing bars 303... The offset direction of 03 is used to adjust the position of the precast wall 2 or the directional reinforcement 303. The position of the precast wall 2 or the directional reinforcement 303 is adjusted to be visible and easy to align with the holes, so that the directional reinforcement 303 and the corresponding positioning hole 403 correspond one-to-one. When the directional reinforcement 303 and the corresponding positioning hole 403 correspond one-to-one, the precast wall 2 continues to fall. The directional reinforcement 303 is inserted into the corresponding positioning hole 403 and the precast wall 2 continues to fall. When the lower wall of the precast wall 2 abuts the upper surface of the fastening unit 302, the reserved reinforcement 101 is inserted into the corresponding grouting sleeve 201 and the falling of the precast wall 2 is stopped.This configuration, once the positioning hole 403 and the directional reinforcement 303 are fully aligned, ensures a one-to-one correspondence between the reserved reinforcement 101 and the grouting sleeve 201. This transforms the previously unseen alignment of the reserved reinforcement 101 and the grouting sleeve 201 into a visible alignment between the directional reinforcement 303 and the positioning hole 403. This reduces the assembly time of the precast wall 2, improves construction efficiency, and solves the problem mentioned in the background technology that construction workers cannot directly observe the positions of the grouting sleeve 201 and the reserved reinforcement 101. This often requires multiple adjustments and confirmations when adjusting the position of the precast wall 2 or the reserved reinforcement 101, prolonging the assembly time of the precast wall 2 and reducing construction efficiency. Afterwards, the precast wall 2 is disassembled... Except for the "L"-shaped positioning plate 401, the fastening unit 302 is removed from the reserved reinforcing bar 101, and the adjusting seat 301, carrying the fastening unit 302 and the "L"-shaped positioning plate 401, is moved away from the precast wall 2 for reuse. Finally, the precast wall 2 is lowered further, landing on the pad for temporary fixation. The lifting equipment is then removed, grouting is performed, and the installation of the precast wall 2 is completed. The advantage of this embodiment is that, by adopting the above arrangement, the previously unseen alignment between the reserved reinforcing bar 101 and the grouting sleeve 201 is transformed into a visible alignment between the directional reinforcing bar 303 and the positioning hole 403, reducing the assembly time of the precast wall 2 and improving construction efficiency.
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13As shown, the fastening unit 302 includes a first fastening rod 30201, a second fastening rod 30202, a wedge-shaped locking block 30203, a sliding frame 30204, a first wedge-shaped driving block 30205, a fastening seat 30206, and a threaded post 30207. The second fastening rod 30202 is slidably connected to the first fastening rod 30201. A wedge-shaped locking block 30203 is provided between the second fastening rod 30202 and the first fastening rod 30201. One end of the wedge-shaped locking block 30203 is fixedly connected to the sliding frame 30204 by welding. The wedge-shaped locking block 30203 is located inside the sliding frame 30204. When the end of the sliding frame 30204 away from the wedge-shaped locking block 30203 abuts against the first fastening rod 30201, the free end of the wedge-shaped locking block 30203 is located on the first fastening rod 30204. Between 0201 and fastening rod two 30202, a sliding frame 30204 is fitted on the outside of fastening rod one 30201. A wedge-shaped drive block one 30205 is provided at the end of the sliding frame 30204 away from the wedge-shaped locking block 30203. The wedge-shaped drive block one 30205 is threadedly connected to a threaded post 30207. One end of the threaded post 30207 is rotatably connected to fastening rod one 30201. The threaded post 30207 rotates clockwise or counterclockwise to drive the wedge-shaped drive block one 30205 closer to or further away from the sliding frame 30204. The wedge-shaped drive block one 30205 moving closer to or further away from the sliding frame 30204 drives the wedge-shaped locking block 30203 closer to or further away from fastening rod two 30202. The wedge-shaped locking block 30203 moving closer to or further away from fastening rod two 30202 drives the fastening rod two 30201... 202 Approaching or moving away from the reserved reinforcing bar 101, fastening rod one 30201 is fixedly connected to fastening seat 30206 by welding. Fastening seat 30206 is fixedly connected to directional reinforcing bar 303 by welding. Directional reinforcing bar 303 can also be connected to fastening seat 30206 by thread. The end of fastening rod one 30201 away from wedge locking block 30203 has a slot one 3020101 opened by the machine tool. The end of fastening rod two 30202 away from wedge locking block 30203 has a slot two 3020201 opened by the machine tool. Slot one 3020101 and slot two 3020201 are used to clamp the reserved reinforcing bar 101. In use, firstly, reverse the threaded column 30207 to move wedge driving block one 30205 away from sliding frame 30204. Operation The operator moves the sliding frame 30204 closer to the wedge-shaped drive block 30205 and then closer to the fastening rod 30201. This causes the wedge-shaped locking block 30203 to move away from the fastening rod 30202. The operator then slides the fastening rod 30202 along the fastening rod 30201, moving the slot 3020201 away from the slot 3020101. This creates an opening between the fastening rods 30201 and 30202, facilitating the installation and removal of the pre-reserved reinforcing bar 101. The operator then guides the pre-reserved reinforcing bar 101 through this opening between the fastening rods 30201 and 30202, ensuring that the inner wall of the slot 3020101 abuts against the pre-reserved reinforcing bar 101.Subsequently, the forward-rotating threaded column 30207 brings the wedge-shaped drive block 30205 closer to the sliding frame 30204, and drives the sliding frame 30204, carrying the wedge-shaped locking block 30203, closer to the fastening rod 30202. The wedge-shaped locking block 30203 drives the fastening rod 30202 to slide along the fastening rod 30201, and causes the slot 3020201 to engage with the slot 3020101 to clamp the reserved steel bar 101; the threaded column 30207 is threadedly connected to the wedge-shaped drive block 30208, and the threaded column 30207 rotates forward or... The reverse rotation is used to drive the second wedge-shaped drive block 30208 away from or towards the sliding frame 30204. The second wedge-shaped drive block 30208 and the first wedge-shaped drive block 30205 are located on both sides of the sliding frame 30204, respectively. The forward rotation of the threaded column 30207 drives the first wedge-shaped drive block 30205 towards the sliding frame 30204, while the second wedge-shaped drive block 30208 moves away from the sliding frame 30204. This drives the sliding frame 30204 to move the wedge-shaped locking block 30203 towards the second fastening rod 30202, and then drives the second fastening rod 30202 towards the fastening rod 30202. The first fixing rod 30201 engages with the second clamping groove 3020201 to clamp the reserved reinforcing bar 101; the reverse rotation of the threaded column 30207 drives the first wedge-shaped drive block 30205 away from the sliding frame 30204, and the second wedge-shaped drive block 30208 moves closer to the sliding frame 30204. The second wedge-shaped drive block 30208 drives the sliding frame 30204 to move the wedge-shaped locking block 30203 away from the second fixing rod 30202; this arrangement facilitates the operation of moving the wedge-shaped locking block 30203 closer to or further away from the second fixing rod 30202. 202; The threaded post 30207 can be connected to the rudder 10 via screws, and the rudder 10 can also be connected to the threaded post 30207 via threads and locked with screws. This configuration facilitates the rotation of the threaded post 30207. Slot 1 3020101 and Slot 2 3020201 are respectively connected to washers 5 via rivets. Washers 5 are rubber washers, but can also be silicone washers. The washers 5 increase friction, improving the stability of the clamping of the reserved reinforcing bar 101 by slots 1 3020101 and 2 3020201.
[0025] like Figure 1 , Figure 14As shown, the horizontal plate of the "L"-shaped positioning plate 401 is provided with several adjustment grooves 404 by a machine tool. Each adjustment groove 404 is spaced apart along the length of the "L"-shaped positioning plate 401. Each adjustment groove 404 corresponds to the grouting sleeve 201 of the precast wall 2. Each adjustment groove 404 contains a positioning block 405, and each positioning block 405 has a positioning hole 403 provided by the machine tool. The positioning hole 403 is adapted to the directional reinforcement 303, and the diameter of the positioning hole 403 is adapted to the diameter of the directional reinforcement 303. This arrangement... The accuracy of the alignment between the positioning hole 403 and the directional steel bar 303 is improved, and the accuracy of the alignment between the reserved steel bar 101 and the grouting sleeve 201 is further improved. The positioning block 405 is rotatably connected to the adjusting rod 406, and the adjusting rod 406 is threadedly connected to the "L"-shaped positioning plate 401. The adjusting rod 406 can be rotated clockwise or counterclockwise to drive the positioning block 405 to slide back and forth along the adjusting groove 404. This setting facilitates the adjustment of the distance between the positioning hole 403 and the grouting sleeve 201 and improves the adaptability of the "L"-shaped positioning plate 401.
[0026] like Figure 1 , Figure 15 , Figure 16 , Figure 22 As shown, a rubber column 6 is installed inside the grouting sleeve 201 of the precast wall 2. The diameter of the rubber column 6 in its natural state is smaller than the diameter of the grouting sleeve 201. One end of the rubber column 6 is located inside the grouting sleeve 201, and the other end of the rubber column 6 protrudes through the grout outlet hole. The rubber column 6 is equipped with an air inlet 601, which is located on the outside of the precast wall 2. The air inlet 601 can be designed with reference to the air inlet of a bicycle tire. The air inlet 601 is detachably connected to an air cylinder, which is used to inflate the rubber column 6. The air inlet 601 is also detachably connected to a stop cap 602. The diameter of the rubber column 6 is larger than the diameter of the grout outlet hole. This design prevents the rubber column 6 from entering the grouting sleeve 201. The rubber column 6 is inflated and expands to fit tightly against the inner wall of the grouting sleeve 201. After inflation, the inflation cylinder is removed, and the blocking cap 602 is threadedly connected to the inflation nozzle 601. After the rubber column 6 is inflated, one end is located 0.5-1 cm inside the grouting sleeve 201. This design facilitates the insertion of the pre-reserved steel bar 101 into the grouting sleeve 201 and punctures the rubber column 6. The punctured rubber column 6 is removed through the grout outlet hole, further verifying the accuracy of the alignment between the pre-reserved steel bar 101 and the grouting sleeve 201.
[0027] like Figure 17 , Figure 18 , Figure 20 , Figure 21As shown, the cast-in-place wall 1 is provided with multiple protective seats 7, each corresponding to a pre-reserved reinforcing bar 101. The protective seats 7 can be fixedly connected to the corresponding pre-reserved reinforcing bars 101 by welding. The protective seats 7 can also be fixedly connected to a positioning steel plate by welding. The upper surface of the protective seats 7 is flush with the surface of the cast-in-place wall 1. The protective seats 7 are detachably connected to protective sleeves 8. The protective seats 7 have internal threads and can also have several slots, spaced apart circumferentially. The depth of the slots is less than the depth of the protective seats 7. The protective sleeves 8 can be threaded to the protective seats 7, or they can be snapped together. When the protective sleeve 8 is in the working position, the reserved steel bar 101 is located inside the protective sleeve 8. This setting can prevent the reserved steel bar 101 from bending during the pouring of the cast-in-place wall 1. The protective seat 7 is detachably connected to the adjustment mechanism 9. When the reserved steel bar 101 deviates from the predetermined position during the pouring of the cast-in-place wall 1, the adjustment mechanism 9 returns the upper part of the deviated reserved steel bar 101 to the predetermined position. The adjustment mechanism 9 includes a base, which can be fixedly connected to the insert by welding. The insert fits into the slot. The insert can also be integrally formed with the base. The base is semi-circular, and the diameter of the semi-circular base is smaller than the diameter of the protective seat 7. The straight edge of the semi-circular base is provided with There is a slot three, which is adapted to the reserved steel bar 101. A block is provided at the end of the semi-circular base away from the slot three. The semi-circular base has a wedge groove, which divides the semi-circular base into a connecting block and an elastic block. The elastic block can be connected to the connecting block by hinge, or it can be integrally formed with the connecting block. The elastic block shifts as the wedge block is inserted, pushing the reserved steel bar 101 to correct its deviation. The depth of the wedge groove is less than the depth of the semi-circular base. The wedge groove is movably connected to the wedge block. The wedge block can be inserted into the wedge groove by hammering it in or by pressing it in with a bolt carrying a pressure plate. The wedge blocks are available in various specifications; different specifications are used for adjustment. For different degrees of deviation of the reserved reinforcing bar 101, such as a deviation of 0.3 mm, a 0.3 mm thick wedge block can be inserted into the wedge groove. This setting makes the deviation adjustment of the reserved reinforcing bar 101 controllable, avoiding the uncontrollability of the deviation adjustment of the reserved reinforcing bar 101. For example, if the deviation is 0.3 mm, it can be adjusted by tools or a hammer, which may correct the deviation of the reserved reinforcing bar 101 by 0.2 mm or 0.4 mm, thus improving the accuracy of the deviation correction of the reserved reinforcing bar 101. The grouting material enters the bottom of the wedge block through the gap between the grouting sleeve, the wedge block, and the protective seat, so that the wedge block, the protective seat, the cast-in-place wall, and the precast wall are connected into one unit.
[0028] A method for installing and positioning precast walls, utilizing any one of the precast wall installation and positioning devices described in the above embodiments, includes the following steps: Step 1: Draw positioning lines on both sides of the reserved steel bar 101. The distance between the two positioning lines is equal to the thickness of the precast wall 2. Determine the position of the reserved steel bar 101. When the position of the reserved steel bar 101 deviates from the predetermined position, the position of the reserved steel bar 101 needs to be adjusted to make the reserved steel bar 101 the predetermined position. Place shims inside the two positioning lines. The shims correspond to the four corners of the precast wall 2. Step 2: The operator positions the adjusting seat 301 on one side of the reserved reinforcing bar 101 and moves the directional reinforcing bar 303 away from the reserved reinforcing bar 101; Step 3: Connect the fastening unit 302, which is fixedly connected to the adjusting seat 301, to the corresponding reserved steel bar 101, and position the fastening unit 302 on the upper section of the reserved steel bar 101; Step 4: Connect the fastening unit 302, which is slidably connected to the adjusting seat 301, to the corresponding reserved steel bar 101, and position the fastening unit 302 on the upper section of the reserved steel bar 101. Step 5: Connect the "L"-shaped positioning plate 401 to the precast wall 2, and position the "L"-shaped positioning plate 401 and the directional steel bar 303 on the same side of the precast wall 2. Step 6: Use lifting equipment to hoist the precast wall 2 to the construction floor and slowly lower the precast wall 2. When the precast wall 2 is 1.5 meters above the floor, manually support the wall and continue to lower the precast wall 2 until it is 1-3 cm away from the "L"-shaped positioning plate 401 and the directional steel bar 303. Stop the precast wall 2 from falling. Step 7: The operator confirms the position of the directional reinforcement 303 and the corresponding positioning hole 403. The diameter of the directional reinforcement 303 matches the diameter of the positioning hole 403. When the deviation between the directional reinforcement 303 and the corresponding positioning hole 403 is small, the operator adjusts the position of the precast wall 2 or the directional reinforcement 303 according to the deviation direction of the directional reinforcement 303 so that the directional reinforcement 303 and the corresponding positioning hole 403 correspond one-to-one. When the directional reinforcement 303 and the corresponding positioning hole 403 correspond one-to-one, the precast wall 2 continues to fall. The directional reinforcement 303 is inserted into the corresponding positioning hole 403 and the precast wall 2 continues to fall. When the lower wall of the precast wall 2 abuts the upper surface of the fastening unit 302, the reserved reinforcement 101 is inserted into the corresponding grouting sleeve 201 and the falling of the precast wall 2 is stopped. Step 8: Remove the “L”-shaped positioning plate 401 from the precast wall 2, remove the fastening unit 302 from the reserved steel bar 101, and move the adjusting seat 301 away from the precast wall 2, carrying the fastening unit 302 and the “L”-shaped positioning plate 401. Step 9: Continue to lower the precast wall 2 so that it lands on the pad block, temporarily fix the precast wall 2, remove the lifting equipment, perform grouting, and complete the installation of the precast wall 2.
