Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for building construction, and specifically to an adjustable support and correction device for installing precast wall panels. Background Technology

[0002] In prefabricated building construction, precast wall panels are typically hoisted to their installation positions on the floor slab using a crane. The floor slab is pre-installed with reinforcing bars corresponding to the mounting holes at the bottom of the precast wall panels. During installation, the precast wall panels need to be lowered so that the reinforcing bars are inserted into the mounting holes. Shims are also placed between the bottom of the precast wall panels and the floor slab to adjust the bottom elevation of the panels. Due to the heavy weight of the precast wall panels, the limited space for descent, and the high precision required for the fit between the reinforcing bars and the mounting holes, construction workers usually need to support the wall panels during the slow lowering process and adjust their lower position using pry bars, shims, or temporary supports.

[0003] Chinese patent document CN206397180U discloses a precast wall panel position adjustment device and a precast wall panel adjustment structure. The precast wall panel position adjustment device includes an upper mounting base, a lifting adjustment pipe, and a lower support base. The lifting adjustment pipe connects the upper mounting base and the lower support base. The upper mounting base is used to fix the precast wall panel, and the lower support base is used to support the floor at the junction with the precast wall panel. The lifting adjustment pipe is used to adjust the installation height of the upper mounting base. This type of structure can adjust the installation height or support status of the precast wall panel to a certain extent, which is beneficial to improving the installation efficiency of the precast wall panel.

[0004] However, the aforementioned devices primarily establish a support and adjustment relationship through an upper mounting base, a lifting adjustment pipe, and a lower support base. The adjustment focuses on the height or support status of the precast wall panel after installation. When the precast wall panel is falling and connecting with the reinforcing bars on the floor slab, the bottom edge of the precast wall panel is not yet stably pressed against the shims or floor slab support position. At this time, the bottom edge of the wall panel is prone to shifting due to slight movements of the crane, uneven manual support, or during the insertion of the reinforcing bars. If the bottom edge of the wall panel deviates from the preset installation position, subsequent adjustment with pry bars is not only laborious but also prone to damaging the bottom corners of the precast wall panel, affecting the stability of the fit between the reinforcing bars and the installation holes, and may also lead to difficulties in placing the shims or the shims shifting under pressure. Therefore, related technologies still require an adjustable support and correction device that can simultaneously support the bottom edge of the wall panel, clamp the side of the wall panel, and push the bottom edge of the wall panel to the installation position during the falling process. Summary of the Invention

[0005] This invention provides an adjustable support and correction device for the installation of precast wall panels, which aims to solve the problem in related technologies that when precast wall panels are lowered to the position of rebar connection and shim placement, the lower part of the wall panel lacks synchronous support and clamping and bottom edge pushing and positioning, which makes the bottom edge of the wall panel easily deviate from the installation position, and subsequent prying and adjustment is laborious and easily damages the bottom corner of the wall panel.

[0006] An adjustable support and correction device for installing precast wall panels includes two sets of mounting seats, two sets of drive components respectively disposed on the two sets of mounting seats, and two sets of adjustment components respectively connected to the ends of the two sets of drive components. Each drive assembly includes a drive base, a rotating shaft, and a telescopic rod. The drive base is mounted on a corresponding mounting base, the rotating shaft is rotatably mounted on the drive base, and the telescopic rod is mounted on the rotating shaft. Each set of adjustment components includes a support plate, side clamps, and a limiting plate. The adjustment components are connected to the end of the telescopic rod. The support plate is used to support the bottom of the precast wall panel, the side clamps are set on one side of the support plate, and the limiting plate is used to abut the bottom edge of the precast wall panel. When the precast wall panel falls onto the two sets of support plates, the two sets of side clamps hold the two sides of the precast wall panel. Before the precast wall panel is fully pressed against the pad, the telescopic rod extends and drives the limiting plate to push the bottom edge of the precast wall panel to the installation position.

[0007] The effect is as follows: by setting two sets of mounting seats, two sets of drive components, and two sets of adjustment components, the lower part of the precast wall panel can be supported and adjusted from both sides of the installation position. When the precast wall panel falls, the bottom edge of the wall panel first falls onto the two sets of support plates, which support the bottom edge of the wall panel. The two sets of side clamps simultaneously clamp the two sides of the wall panel, keeping the lower part of the wall panel under control before the reinforcing bars are inserted into the installation holes and the shims are placed. Then the telescopic rod extends, driving the adjustment components to move towards the wall panel installation position. The limiting plate abuts against the bottom edge of the precast wall panel and pushes it to the installation position. Thus, the wall panel falling, lateral clamping, and bottom edge pushing and positioning form a continuous action chain, reducing the need for construction workers to pry the bottom of the wall panel after it has been placed, reducing the risk of damage to the bottom corner of the wall panel, and improving the accuracy of the correspondence between the bottom edge position of the wall panel and the design installation line.

[0008] Preferably, each set of mounting bases is provided with fixing holes, and fixing bolts for connecting with the floor slab are inserted into the fixing holes. The two sets of mounting bases are fixed to both sides of the precast wall panel installation position by fixing bolts.

[0009] Its effect is that by fixing the two sets of mounting seats to the floor slab through fixing holes and fixing bolts, the drive component and the adjustment component have a stable installation foundation. The two sets of mounting seats are located on both sides of the installation position of the precast wall panel, which can form symmetrical support and clamping from both sides of the wall panel, reducing the wall panel tilting problem caused by unilateral force, and at the same time, it is convenient to determine the installation benchmark of the device in advance according to the construction layout position.

[0010] Preferably, the drive seat is provided with a rotating mounting hole, the rotating shaft passes through the rotating mounting hole, and the telescopic rod is connected to the rotating shaft so that the telescopic rod can rotate relative to the drive seat with the rotating shaft.

[0011] The effect is that by setting a rotating mounting hole on the drive seat and inserting the rotating shaft into the rotating mounting hole, the telescopic rod can not only extend and retract along its own length, but also rotate relative to the drive seat with the rotating shaft. In this way, when the precast wall panel falls onto the support plate, the adjusting component can adapt to the pressure state of the bottom edge of the wall panel, avoiding rigid contact between the support plate and the bottom edge of the wall panel, while allowing the side clamps to fit more smoothly against the side of the wall panel.

[0012] Preferably, the telescopic rod includes a fixed rod and a movable rod slidably sleeved within the fixed rod. The fixed rod is connected to a rotating shaft, and the end of the movable rod away from the fixed rod is connected to an adjusting component to drive the adjusting component closer to or further away from the installation position of the precast wall panel.

[0013] Its effect is as follows: through the telescopic cooperation of the fixed rod and the movable rod, the adjusting component can be positioned in a convenient location to receive the bottom edge of the precast wall panel before it falls, and then move towards the installation position after the bottom edge of the wall panel is supported by the support plate and clamped by the side clamps. The movable rod moves the adjusting component closer to or further away from the wall panel installation position, and can make small-range push corrections to the bottom edge of the wall panel according to the actual falling deviation, so that the bottom edge of the wall panel is finally close to the designed installation position.

[0014] Preferably, the support plate is fixedly connected to the side clamping plate, and the side clamping plate extends upward from one side of the support plate, forming a clamping area between the support plate and the side clamping plate for accommodating the lower side of the precast wall panel.

[0015] Its effect is that after the support plate and the side clamp are fixedly connected, the two can support the bottom of the wall panel as a whole. This structure can limit the lateral swaying of the bottom of the wall panel during the continued falling of the wall panel, so that when the limiting plate pushes against the bottom edge of the wall panel, the bottom of the wall panel is not easy to disengage from the adjustment component, thereby improving the stability of the pushing and positioning action.

[0016] Preferably, the limiting plate is disposed on the side of the support plate near the bottom edge of the precast wall panel, and the side of the limiting plate facing the bottom edge of the precast wall panel forms a pushing surface, which is used to push the bottom edge of the precast wall panel to move to the installation position when the telescopic rod is extended.

[0017] Its effect is as follows: the limiting plate is set on the side of the support plate close to the bottom edge of the precast wall panel, so that after the bottom edge of the wall panel is supported by the support plate, the limiting plate can directly act on the bottom edge of the wall panel. When the telescopic rod extends, the pushing surface contacts the bottom edge of the wall panel and pushes the bottom edge of the wall panel in the direction of the installation position, so that the bottom position of the wall panel can be adjusted before the shim is fully compacted. This avoids prying the wall panel from the end or bottom corner of the wall panel and also makes the bottom edge of the wall panel correspond to the preset installation position.

[0018] Preferably, a reset torsion spring is provided on the rotating shaft. One end of the reset torsion spring is connected to the drive seat, and the other end is connected to the rotating shaft, so that the rotating shaft drives the telescopic rod and the adjusting assembly to maintain the initial support state with the opening facing upward.

[0019] Its effect is that by setting a reset torsion spring on the rotating shaft, when the device is not under the pressure of the precast wall panel, the rotating shaft can drive the telescopic rod and the adjustment component to automatically maintain the initial support state with the opening facing upward, so as to maintain a better support posture before the wall panel falls, making it easier for the bottom of the wall panel to accurately enter the support and clamping area formed by the two sets of support plates and the side clamping plates, reducing the need for manual flipping or straightening of the adjustment component.

[0020] Preferably, a limit block is provided on the drive seat. The limit block is located on the rotation path of the telescopic rod and is used to limit the telescopic rod from continuing to rotate under the action of the reset torsion spring, and to make the end of the support plate away from the telescopic rod higher than the rotating shaft.

[0021] Its effect is as follows: the limiting block can limit the initial rotation angle of the telescopic rod and the adjusting component, preventing the adjusting component from overturning under the action of the return torsion spring. By making the end of the support plate away from the telescopic rod higher than the pivot, the support plate is in an upward-opening supporting posture, making it easier for the bottom of the precast wall panel to enter the clamping area formed by the support plate and the side clamp when it falls. At the same time, the downward pressure of the wall panel can cause the adjusting component to rotate smoothly and form a stable support.

[0022] Preferably, the side clamp includes a clamp body and an elastic rod disposed on the side of the clamp body facing the precast wall panel. The elastic rod can extend and retract in the direction of approaching or moving away from the clamp body, and an abutment pad is provided at the end of the elastic rod near the precast wall panel.

[0023] Its effects are as follows: by setting elastic rods on the clamping plate body, the side clamping plates can expand and contract to compensate for the local flatness deviation of the wall panel side when they contact the side of the precast wall panel; the contact pads with the side of the precast wall panel can reduce local damage caused by hard contact, while increasing the clamping contact area, making the clamping of the two sets of side clamping plates on the two sides of the wall panel more stable.

[0024] Preferably, the system further includes a connection and correction assembly, which includes a short connecting rod, a long connecting rod, and a position adjustment component. One end of both the short and long connecting rods is used to connect to the precast wall panel, and the other end of both the short and long connecting rods is connected to the mounting base via the position adjustment component. The position adjustment component is used to adjust the position of the short and long connecting rods on the mounting base to adjust the verticality of the precast wall panel.

[0025] Its effect is as follows: after the bottom edge of the wall panel is pushed to the installation position by the limiting plate and supported by the shim, an adjustable connection relationship is formed between the wall panel and the mounting base through the short connecting rod, the long connecting rod and the position adjustment component. The position of the short connecting rod and the long connecting rod on the mounting base can be changed, thereby fine-tuning the verticality of the precast wall panel, so that the wall panel is closer to the designed vertical state after the bottom position is determined, and improving the accuracy of subsequent fixing and grouting construction.

[0026] The beneficial effects of this invention are as follows: 1. This invention uses a support plate and side clamps in two sets of adjustment components to simultaneously support and clamp the lower part of the precast wall panel, so that the precast wall panel is in a controlled state before the crane lowers it, the floor slab reinforcement is inserted into the installation hole, and the shims are placed. Compared with relying solely on manual support or prying the bottom of the wall panel after it is placed, the bottom of the wall panel can be supported by the support plate during the descent, and the two sides can be restricted by the side clamps, reducing the shaking of the lower part of the wall panel and the displacement of the bottom edge, providing a stable foundation for the limiting plate to push against the bottom edge of the wall panel later.

[0027] 2. In this invention, a limiting plate is set on the adjusting assembly, and the adjusting assembly is moved by a telescopic rod. This allows the limiting plate to press against the bottom edge of the wall panel and push it to the installation position while the bottom edge of the wall panel is supported by the support plate and the side of the wall panel is clamped by the side clamps. This action occurs before the wall panel is fully compacted with the shims, allowing for minor adjustments to the bottom edge of the wall panel during the construction phase when the crane is still bearing the main weight. This reduces the difficulty of adjusting the pry bar after the wall panel is in place and reduces the risk of damage to the bottom corner of the wall panel and uneven pressure on the shims.

[0028] 3. The present invention uses a rotating shaft, a reset torsion spring and a limiting rotating block to enable the telescopic rod and the adjusting assembly to maintain an initial supporting state with the opening facing upward when not supporting a wall panel, and to generate adaptive rotation when the wall panel falls and is compressed. This facilitates the entry of the lower opening of the wall panel into the clamping area formed by the support plate and the side clamping plate, and avoids excessive flipping or rigid contact of the adjusting assembly with the lower opening of the wall panel, thereby improving the stability and ease of operation of the device when it is used repeatedly on the construction site.

[0029] 4. The present invention is equipped with a connection and correction component. After the bottom edge of the wall panel is pushed to the installation position, the verticality of the precast wall panel is further adjusted by short connecting rods, long connecting rods and position adjustment components. This makes the bottom positioning of the wall panel and the overall verticality correction of the wall panel a continuous construction process, reducing the error caused by the scattered cooperation of various temporary tools, and improving the installation efficiency and accuracy of the precast wall panel.

[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figures 1 to 8 As shown, an adjustable support and correction device for installing precast wall panels includes two sets of position adjustment components 43 that adjust their positions on the mounting base 1, two sets of drive components 2, two sets of adjustment components 3, and a connection and correction component 4.

[0041] Two sets of mounting bases 1 can be fixedly installed on the floor slab and are respectively arranged on both sides of the precast wall panel installation position; two sets of drive components 2 are respectively set on the two sets of mounting bases 1; two sets of adjustment components 3 are respectively connected to the ends of the two sets of drive components 2. When the precast wall panel is hoisted to the installation position on the floor slab by a crane, the two sets of adjustment components 3 support and clamp the bottom edge of the precast wall panel from both sides of the lower part of the precast wall panel, and the two sets of drive components 2 then push the corresponding adjustment components 3 to move, so that the adjustment components 3 push the bottom edge of the precast wall panel to the preset installation position. The connecting correction component 4 is used to further adjust the verticality of the precast wall panel after the bottom edge of the precast wall panel is positioned.

[0042] like Figure 1 and Figure 2As shown, the mounting base 1 is a steel base, which can be formed by welding steel plates, channel steel, or shaped steel. Each mounting base 1 has a fixing hole 11, and a fixing bolt for connecting to the floor slab passes through the fixing hole 11. During construction, the positions of the two sets of mounting bases 1 are first determined according to the wall panel installation control lines on the floor slab, and then the two sets of mounting bases 1 are fixed to both sides of the precast wall panel installation position using fixing bolts. The two sets of mounting bases 1 form a stable installation foundation, so that the subsequent drive component 2 can have a reliable reaction force when pushing the adjustment component 3, avoiding overall displacement of the device when pushing against the bottom edge of the precast wall panel.

[0043] like Figures 2 to 5 As shown, each drive assembly 2 includes a drive base 21, a rotating shaft 22, and a telescopic rod 23. The drive base 21 is fixedly mounted on the corresponding mounting base 1. The drive base 21 has a rotating mounting hole 211. The rotating shaft 22 passes through the rotating mounting hole 211 and can rotate relative to the drive base 21. The telescopic rod 23 is mounted on the rotating shaft 22, allowing the telescopic rod 23 to rotate with the rotating shaft 22. The telescopic rod 23 can be an electric telescopic rod, a hydraulic telescopic rod, or a screw-type telescopic rod. Alternatively, a manually adjustable telescopic rod can be used depending on the construction site conditions. The end of the telescopic rod 23 is connected to the adjusting assembly 3, which is used to move the adjusting assembly 3 closer to or further away from the installation position of the precast wall panel.

[0044] By mounting the telescopic rod 23 on the rotating shaft 22, the adjusting assembly 3 can not only adjust its position forward and backward under the action of the telescopic rod 23, but also swing at a certain angle with the rotating shaft 22. When the bottom of the precast wall panel falls onto the adjusting assembly 3, the adjusting assembly 3 can adapt to the downward pressure of the precast wall panel and rotate accordingly, reducing the rigid contact between the support plate 31 and the bottom of the precast wall panel, making it easier for the bottom of the precast wall panel to enter the support and clamping area formed by the two sets of adjusting assemblies 3.

[0045] like Figures 3 to 5 As shown, each adjusting assembly 3 includes a support plate 31, a side clamping plate 32, and a limiting plate 33. The adjusting assembly 3 is connected to the end of the telescopic rod 23. The support plate 31 supports the lower edge of the precast wall panel. The side clamping plate 32 is located on one side of the support plate 31 and extends upward to clamp or limit the side of the precast wall panel. The limiting plate 33 is located on the side of the support plate 31 near the bottom edge of the precast wall panel to abut against the bottom edge of the precast wall panel. The support plate 31, the side clamping plate 32, and the limiting plate 33 can be connected into an integral structure by welding, bolting, or integral molding so that they can move synchronously when the telescopic rod 23 extends and retracts.

[0046] The support plate 31 is the main load-bearing component supporting the bottom edge of the precast wall panel. Its upper surface can be flat or coated with a smooth coating to reduce the friction between the support plate 31 and the bottom edge of the precast wall panel. The support plates 31 of the two sets of adjustment components 3 are symmetrically arranged so that when the precast wall panel is lowered by the crane, the bottom edge of the precast wall panel can fall onto the two sets of support plates 31. Since the two sets of support plates 31 are located on both sides of the bottom edge of the precast wall panel, they can provide balanced support for the lower part of the precast wall panel, reducing the tilting of the precast wall panel caused by unilateral support.

[0047] Side clamps 32 are disposed on one side of the support plate 31 and extend upward from the support plate 31. A clamping area for accommodating the lower side of the precast wall panel is formed between the support plate 31 and the side clamps 32. After the lower part of the precast wall panel falls onto the support plate 31, both sides of the precast wall panel contact the two sets of side clamps 32 respectively, and the two sets of side clamps 32 clamp and limit the lower part of the precast wall panel from both sides. Through this structure, the precast wall panel can maintain a relatively stable lower position before the shims are placed, reducing the swaying of the lower part of the wall panel caused by slight movements of the crane or uneven manual support.

[0048] like Figure 5 and Figure 7 As shown, the limiting plate 33 is located on the side of the support plate 31 near the bottom edge of the precast wall panel, forming a pushing surface on the side of the limiting plate 33 facing the bottom edge of the precast wall panel. When the telescopic rod 23 extends, the adjusting assembly 3 moves as a whole towards the installation position of the precast wall panel, and the pushing surface of the limiting plate 33 abuts against the bottom edge of the precast wall panel, pushing the bottom edge of the precast wall panel to the preset installation position. The limiting plate 33 is mainly used to push against the bottom edge of the precast wall panel for fine-tuning of the installation position, rather than prying the wall panel from the end of the wall panel. After the bottom edge of the wall panel is pushed to the installation position, the construction personnel can insert a shim between the bottom edge of the precast wall panel and the floor slab from the other side of the precast wall panel to support the bottom elevation of the precast wall panel.

[0049] like Figures 4 to 7 As shown, a return torsion spring 24 is installed on the rotating shaft 22. One end of the return torsion spring 24 is connected to the drive seat 21, and the other end is connected to the rotating shaft 22. The return torsion spring 24 is used to maintain the initial support state with the opening facing upward by driving the telescopic rod 23 and the adjustment component 3 through the rotating shaft 22 when the precast wall panel is not pressed down on the adjustment component 3. In this initial support state, the end of the support plate 31 away from the telescopic rod 23 is higher than the rotating shaft 22, so that the support plate 31 forms an inclined support posture that is convenient for receiving the bottom opening of the precast wall panel. In this way, when the crane lowers the precast wall panel, the construction personnel do not need to manually support the adjustment component 3 to make the bottom opening of the precast wall panel fall smoothly between the two sets of support plates 31.

[0050] like Figures 5 to 7As shown, a limiting block 25 is also provided on the drive base 21, and the limiting block 25 is located on the rotation path of the telescopic rod 23. The limiting block 25 is used to limit the continued rotation of the telescopic rod 23 under the action of the return torsion spring 24, preventing the telescopic rod 23 and the adjusting assembly 3 from overturning. After the limiting block 25 limits the initial angle of the telescopic rod 23, it can keep the end of the support plate 31 away from the telescopic rod 23 at a position higher than the rotating shaft 22, thereby ensuring that the support plate 31 is in a stable open-up state before the wall panel falls. After the lower edge of the precast wall panel presses against the support plate 31, the support plate 31 and the side clamp 32 rotate adaptively around the rotating shaft 22 with the telescopic rod 23, thereby making the side clamp 32 fit more closely to the side of the precast wall panel.

[0051] like Figures 5 to 7 As shown, the side clamp 32 includes a clamp body 321, an elastic rod 322, and an abutment pad. The clamp body 321 is connected to the support plate 31 and extends upward. The elastic rod 322 is located on the side of the clamp body 321 facing the precast wall panel, and the elastic rod 322 can extend and retract in the direction of approaching or moving away from the clamp body 321. The abutment pad is located at the end of the elastic rod 322 near the precast wall panel and is used to contact the side of the precast wall panel. The abutment pad can be a rubber pad, a nylon pad, or other wear-resistant buffer pad. Since there may be local flatness deviations on the side of the precast wall panel, the elastic rod 322 can compensate for the expansion and contraction when the side clamp 32 clamps the side of the precast wall panel, so that the abutment pad maintains stable contact with the side of the precast wall panel.

[0052] like Figures 1 to 4 , Figure 8 As shown, the connection correction assembly 4 includes a short connecting rod 41, a long connecting rod 42, and a position adjustment component 43. One end of the short connecting rod 41 and the long connecting rod 42 is connected to a pre-set connecting hook on the precast wall panel. The other end of the short connecting rod 41 and the long connecting rod 42 is connected to the mounting base 1 via the position adjustment component 43. The position adjustment component 43 can adjust the position of the short connecting rod 41 and the long connecting rod 42 on the mounting base 1. The position adjustment component 43 consists of a screw rod installed on the mounting base 1 and a slider that cooperates with the screw rod. By adjusting the position of the slider, the position of the short connecting rod 41 and the long connecting rod 42 on the mounting base 1 can be changed, thereby fine-tuning the verticality of the precast wall panel. Furthermore, the lengths of the short connecting rod 41 and the long connecting rod 42 are adjustable to accommodate precast wall panels of different specifications. The short connecting rod 41 and the long connecting rod 42 can be two adjustable-length screw rods.

[0053] In actual construction, after the bottom edge of the precast wall panel is pushed to the installation position by the limiting plate 33 and initially supported by the shims, the precast wall panel may still be in a slightly tilted state. At this time, by connecting the short connecting rod 41 and the long connecting rod 42, and adjusting their positions on the mounting base 1 by the position adjustment component 43, the precast wall panel can be pushed or pulled, gradually adjusting it from a tilted state to a near-vertical state. Since the bottom edge of the wall panel has been positioned by the two sets of adjustment components 3, the verticality adjustment of the connecting correction component 4 can be based on a relatively stable bottom position, avoiding repeated mutual interference between the bottom position and the upper verticality of the wall panel.

[0054] Based on the above-described device, the working process and working principle of the present invention are as follows: S1. Installation Preparation: Before installing the precast wall panels, first mark the installation control lines on the floor slab, and determine the fixing positions of the two sets of mounting seats 1 according to the position of the reinforcing bars on the floor slab and the position of the mounting holes at the bottom of the precast wall panels. Then, arrange the two sets of mounting seats 1 on both sides of the installation position of the precast wall panels, and fix the mounting seats 1 to the floor slab with the fixing bolts in the fixing holes 11. At this time, the drive assembly 2 and the adjustment assembly 3 are installed on the corresponding mounting seats 1, and the return torsion spring 24 causes the rotating shaft 22 to drive the telescopic rod 23 and the adjustment assembly 3 to maintain the initial support state with the opening facing upward.

[0055] S2. Wall Panel Lowering Support: The upper end of the precast wall panel is lifted and transported to the installation position by a crane, and the crane slowly lowers the precast wall panel. When the lower edge of the precast wall panel approaches the installation area of ​​the floor slab reinforcement and shims, the lower edge of the precast wall panel falls onto the support plates 31 of the two sets of adjustment components 3. Since the end of the support plate 31 away from the telescopic rod 23 is higher than the pivot 22, the lower edge of the precast wall panel can smoothly enter the clamping area formed by the support plate 31 and the side clamping plates 32. As the precast wall panel continues to fall, the support plate 31 is subjected to the downward pressure of the wall panel and drives the telescopic rod 23 to rotate adaptively around the pivot 22. The two sets of side clamping plates 32 respectively abut against the two sides of the precast wall panel, forming a clamping and limiting effect on the lower part of the precast wall panel.

[0056] S3. Rebar Connection and Bottom Edge Pushing: With the bottom edge of the precast wall panel supported by two sets of support plates 31 and the sides clamped by two sets of side clamping plates 32, the reinforcing bars on the floor slab are inserted into the corresponding installation holes of the precast wall panel, thus initially limiting the length of the precast wall panel. If there is a small deviation between the bottom of the wall panel and the preset installation position, the two sets of telescopic rods 23 extend, driving the corresponding adjustment components 3 to move towards the installation position of the precast wall panel. At this time, the pushing surface of the limiting plate 33 abuts against the bottom edge of the precast wall panel and pushes the bottom edge of the precast wall panel to the preset installation position. Since the precast wall panel is still mainly supported by the crane at this stage, the adjustment resistance of the bottom edge of the wall panel is small, which can reduce the construction difficulty of adjusting the bottom of the wall panel with pry bars after it is placed.

[0057] S4. Shim Placement: After the side of the precast wall panel closest to the limiting plate 33 is pushed to the preset installation position, the construction worker inserts a shim between the bottom edge of the precast wall panel and the floor slab from the other side of the precast wall panel. The shim is used to support the bottom of the precast wall panel and adjust the bottom elevation of the precast wall panel. Since the limiting plate 33 has already pushed the bottom edge of the precast wall panel to the installation position, it is not easy for the shim to be misaligned or unevenly placed, and the bottom edge of the wall panel can be pressed stably on the shim.

[0058] S5. Verticality Correction: After the shims are placed, connect the short connecting rod 41 and the long connecting rod 42, and adjust their positions using the position adjusting component 43. During adjustment, the connecting correction component 4 applies a pushing and pulling action to the precast wall panel, gradually adjusting it from a slightly tilted state to a near-vertical state. After adjustment, the precast wall panel rests on the shims, and the short connecting rod 41 and the long connecting rod 42 fix it in place.

[0059] S6. Device Retraction: After the bottom position and verticality of the precast wall panel are adjusted, the telescopic rod 23 in the drive assembly 2 retracts, driving the adjustment assembly 3 away from the installation position of the precast wall panel, causing the support plate 31, side clamping plate 32, and limiting plate 33 to exit the lower area of ​​the precast wall panel. The reset torsion spring 24 drives the rotating shaft 22 to reset, causing the telescopic rod 23 and the adjustment assembly 3 to return to the initial support state with the opening facing upward, so that they can be used again during the next installation of the precast wall panel.

[0060] Through the above-described process, this invention enables continuous support, clamping, pushing, and correction of the lower part of the precast wall panel during the lowering of the precast wall panel, rebar splicing, shim placement, and verticality correction. Compared with related technologies that only adjust the wall panel after it has been positioned using support rods, pry bars, or shims, this invention can complete the positioning of the bottom edge of the wall panel before the shims are fully compacted, reducing damage to the bottom corners of the wall panel and the risk of shim misalignment, thus improving the installation accuracy and construction efficiency of the precast wall panel.

[0061] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
