Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to an installation device and method for prefabricated wall panels. Background Technology

[0002] Precast wall panels are reinforced concrete slab components manufactured in prefabrication plants for building assembly. The precast wall panels prepared in the factory can be used directly on the construction site without the need for on-site formwork and pouring, thereby reducing on-site wet work and improving construction efficiency.

[0003] The installation of precast wall panels is carried out using a crane for hoisting combined with manual assistance. Multiple perforations are spaced apart on the precast wall panels, and corresponding steel reinforcement groups are pre-installed on another precast wall panel connected to it. The crane first lifts the precast wall panel and moves it to the construction area. When the precast wall panel is lowered to a certain distance from the installation position (usually about 600mm), it stops. At this time, the construction workers hold the precast wall panel to control its descent direction. It stops again at a certain distance from the top of the embedded steel reinforcement (usually about 20mm), and then the construction workers then... The position of the precast wall panels needs to be adjusted. A reflector is used to align the reinforcing bars and perforations. Once the reinforcing bars and perforations are aligned, the precast wall panels are slowly lowered so that the reinforcing bars are inserted into the corresponding perforations. Concrete is then poured into the perforations to fix the two precast wall panels. After the precast wall panels are fixed, the tower crane unloads its load while the precast wall panels are fixed with inclined support bolts. One end of the inclined support bolt is fixedly connected to the precast wall panel, and the other end is fixedly connected to the ground in the construction area to support the precast wall panels, thus completing the installation of the precast wall panels.

[0004] In actual construction, the alignment of precast wall panels mainly relies on visual observation by construction workers using a reflector to reflect the light. This often makes it difficult to align the precast wall panels on the first try, requiring repeated adjustments. During this process, the precast wall panels are only pulled by the lifting components, which can easily cause swaying during the adjustment process, further increasing the difficulty of alignment. As a result, the installation efficiency of precast wall panels is low. Summary of the Invention

[0005] To address the problems existing in the above-mentioned technologies, this application provides an installation device and installation method for prefabricated wall panels.

[0006] The installation device for precast wall panels provided in this application adopts the following technical solution:

[0007] An installation device for a precast wall panel includes a mounting frame with a movable component for horizontal sliding. A mounting seat is slidably mounted on the mounting frame, and a first driving member is provided on the mounting frame to drive the mounting seat to slide vertically. A clamping member is slidably mounted on the mounting seat for clamping and fixing the precast wall panel, and a second driving member is provided on the mounting seat to drive the clamping member to slide horizontally. A positioning seat is provided on the mounting frame, and a positioning rod is slidably mounted on the positioning seat. A third driving member is provided on the positioning seat to drive the positioning rod to slide horizontally. A plug rod is coaxially slidably connected to the end of the positioning rod, and a guide surface is provided at the end of the plug rod. An elastic member abutting against the plug rod is provided inside the positioning rod.

[0008] By adopting the above technical solution, when installing precast wall panels, the precast wall panels are clamped and fixed to the mounting frame by the clamping components on the mounting base. As the crane lifts the precast wall panels, the mounting frame moves along with them. When the precast wall panel moves to the construction area, it slowly descends until the moving component contacts the ground at the construction area, with the positioning rod located at the very end of the steel reinforcement group consisting of multiple steel bars. The moving component then drives the mounting frame to slide, which in turn moves the positioning rod. The positioning rod slides along the direction closest to the steel reinforcement group until it abuts against the very end steel bar of the group. At this point, the positioning rod cannot continue to slide in the same direction. The mounting frame is then fixed in place, and the precast wall panel is now positioned on the side of the positioning rod closest to the steel reinforcement group, exposing the positioning rod. Subsequently, the clamping component is driven by the second driving component to slide horizontally. The clamping component drives the precast wall panel to slide along the direction close to the positioning rod. As the precast wall panel moves, its end continuously approaches the positioning rod. During this movement, the end of the precast wall panel passes through the guide surface, causing the insertion rod to slide on the positioning rod. The end of the insertion rod will then be in contact with the bottom surface of the precast wall panel, at which point the elastic element is in a compressed state. As the precast wall panel continues to move, the perforation at the very end of the precast wall panel will move to the insertion rod. At this point, the rebound of the elastic element pushes the insertion rod to move, causing it to insert into the perforation at the very end. At this point, the distance between the perforation at the very end and the steel reinforcement at the very end is the width of one insertion rod. The positioning rod is then driven by the third driving component to slide away from the precast wall panel. The second driving component then retracts the precast wall panel by the width of a single insertion rod, thereby aligning multiple perforations and rebar assemblies. Subsequently, the first driving component drives the mounting base to slide vertically. The sliding of the mounting base causes the clamping component to slide, which in turn moves the precast wall panel downward, allowing multiple rebars to be inserted into their corresponding perforations. Construction workers can then proceed with subsequent pouring and support operations, thus completing the installation of the precast wall panel. The coordination of the various components in the above process enables precise alignment of the perforations and corresponding rebars on the precast wall panel, eliminating the need for construction workers to repeatedly move and adjust the position of the precast wall panel. This reduces the effort required for construction workers during the alignment process and improves the installation efficiency of the precast wall panel.

[0009] Optionally, the positioning rod includes a first vertical rod, a horizontal rod, and a second vertical rod. One end of the horizontal rod is fixedly connected to the first vertical rod, and the other end is fixedly connected to the second vertical rod. The first vertical rod and the second vertical rod are located on both sides of the horizontal rod. The third driving member is used to drive the first vertical rod to slide horizontally. The insertion rod is slidably mounted on the second vertical rod, and the elastic member is disposed inside the second vertical rod.

[0010] By adopting the above technical solution, the third driving member drives the first vertical rod to slide horizontally. The first vertical rod then drives the horizontal rod and the second vertical rod to slide. The second vertical rod then slides in the direction close to the rebar group. When the first vertical rod moves to abut against the end rebar, the sliding of the first vertical rod in the same direction is restricted. At this time, the second vertical rod is coaxial with the rebar and located directly above the rebar. During the process of the clamping member driving the precast wall panel to slide in the direction close to the positioning rod, the insert on the second vertical rod can be inserted into the through hole of the precast wall panel. The third driving member then drives the positioning rod to slide away from the precast wall panel. At this time, the through hole at the end of the precast wall panel is located directly above the end rebar. Therefore, there is no need to retract the precast wall panel. After the positioning rod moves away from the precast wall panel, the first driving member can drive the mounting base to slide vertically, so that multiple rebars are inserted into the corresponding through holes, thereby improving the convenience of using the device.

[0011] Optionally, a photosensitive sensor is provided on the positioning rod, the photosensitive sensor is electrically connected to the third driving component, and the insertion rod can slide to block the photosensitive sensor.

[0012] By adopting the above technical solution, when the insertion rod is not inserted into the hole, the end of the insertion rod is in contact with the bottom surface of the precast wall panel, at which time the insertion rod blocks the photosensitive sensor; when the insertion rod is inserted into the hole, the rebound of the elastic element pushes the insertion rod to slide, so that the photosensitive sensor is exposed. At this time, the photosensitive sensor transmits a signal, and the third driving element receives the signal, and then drives the positioning rod to slide away from the precast wall panel, thereby achieving precise control of the positioning rod.

[0013] Optionally, the mounting bracket is provided with a telescopic component, and the telescopic component is provided with an auxiliary support seat.

[0014] Furthermore, the auxiliary support base includes a support plate disposed on the telescopic member, a horizontal plate is fixed to the end of the support plate, and a reinforcing rod is disposed between the horizontal plate and the support plate.

[0015] By adopting the above technical solution, when the moving component drives the mounting frame to slide until the positioning rod abuts against the end of the reinforcing bar, the auxiliary support seat is driven to move downward through the telescopic component. The horizontal plate and the support plate move downward as a result until the horizontal plate contacts the ground at the construction area. The cooperation between the horizontal plate and the support plate provides auxiliary support for the mounting frame, improving the overall stability of the device and preventing the mounting frame from moving during the alignment of the precast wall panel. The reinforcing rod is used to improve the strength of the connection between the support plate and the horizontal plate, further improving the overall stability of the auxiliary support seat.

[0016] Optionally, the reinforcing rod includes a fixed rod and an adjusting rod, the adjusting rod being slidably connected to the fixed rod coaxially, and the fixed rod being provided with a limiting member for fixing the position of the adjusting rod; a connecting seat is hinged to one end of the fixed rod and the adjusting rod away from each other, one connecting seat being detachably connected to the horizontal plate and the other connecting seat being detachably connected to the support plate, and either connecting seat can be detachably connected to a precast wall panel or the ground.

[0017] By adopting the above technical solution, the cooperation of the fixed rod and the adjusting rod forms a reinforcing rod assembly. The connecting seats at the ends of the fixed rod and the adjusting rod are respectively connected to the support plate and the horizontal plate, thereby connecting the reinforcing rod assembly to the support plate and the horizontal plate, thus improving the strength of the connection between the support plate and the horizontal plate. The fixed rod slides coaxially within the adjusting rod, thus allowing the length of the reinforcing rod assembly to change as the fixed rod slides. After the precast wall panel is aligned, multiple reinforcing bars are inserted into the corresponding holes, thereby completing the fixing of the precast wall panel. At this time, one connecting seat can be removed and connected to the ground at the construction area, and the other connecting seat can be connected to the precast wall panel. The reinforcing rod thus provides diagonal support for the precast wall panel, thereby further improving the applicability of the device and eliminating the need to use additional components for diagonal support of the precast wall panel.

[0018] Optionally, the adjusting rod is provided with a plurality of first limiting holes evenly distributed along the axial direction, the fixing rod is provided with a second limiting hole, and the limiting member includes a limiting pin passing through the second limiting hole, the limiting pin passing through any of the first limiting holes.

[0019] By adopting the above technical solution, the adjusting rod can be fixed on the fixed rod by simultaneously inserting the limiting pin into the second limiting hole and any one of the first limiting holes. The operation is simple and convenient. Furthermore, by uniformly setting multiple first limiting holes along the axial direction of the adjusting rod, the overall adjustment range of the reinforcing rod can be wide.

[0020] Optionally, the clamping member includes a first vertical plate and a second vertical plate arranged in parallel and opposite to each other. The second driving member is used to drive the first vertical plate to slide horizontally. A first adjusting bolt and a second adjusting bolt are rotatably connected to the first vertical plate. The first adjusting bolt and the second adjusting bolt are both slidably engaged with the second vertical plate. The second vertical plate is provided with a waist-shaped hole for the second adjusting bolt to slide horizontally.

[0021] By adopting the above technical solution, the first vertical plate and the second vertical plate are arranged parallel and opposite to each other, both of which are vertically arranged. When the precast wall panel is installed and fixed by the installation device, the precast wall panel is placed between the first vertical plate and the second vertical plate. The second vertical plate is slid so that the second vertical plate is in close contact with the precast wall panel. At this time, the side of the precast wall panel away from the second vertical plate is in contact with the first vertical plate. At this time, the side end of the precast wall panel abuts against the first adjusting bolt. The nut of the first adjusting bolt is turned so that the nut of the first adjusting bolt is in close contact with the second vertical plate to fix the position of the second vertical plate. Then, the second adjusting bolt is slid in the slotted hole until the second adjusting bolt abuts against the side end of the precast wall panel away from the first adjusting bolt. The nut of the second adjusting bolt is turned so that the nut of the second adjusting bolt is in close contact with the second vertical plate. At this time, the precast wall panel is clamped in the cavity formed by the first vertical plate, the second vertical plate, the first adjusting bolt, and the second adjusting bolt, thereby fixing the precast wall panel on the installation device.

[0022] Optionally, the first vertical plate is provided with a plurality of parallel first adjusting bolts, and the plane in which the axes of the plurality of first adjusting bolts lie is a vertical plane.

[0023] By adopting the above technical solution, when the precast wall panel is located between the first vertical plate and the second vertical plate, the side end of the precast wall panel abuts against multiple first adjusting bolts, and the plane where the axis of the multiple first adjusting bolts is located is a vertical plane. This ensures that after the precast wall panel is clamped and fixed, the precast wall panel is in a vertical state, thereby avoiding the precast wall panel from tilting and affecting the subsequent alignment work.

[0024] This application also provides a method for installing precast wall panels, using the aforementioned installation device for precast wall panels, comprising the following steps:

[0025] S1: The prefabricated wall panel is fixed on the mounting frame using clamps;

[0026] S2: Lift the precast wall panel and move it to the construction area.

[0027] S3: The precast wall panel slowly descends, the moving component contacts the ground at the construction area location, and the positioning rod is located at the very end of the steel reinforcement group composed of multiple steel bars;

[0028] S4: The moving component drives the mounting bracket to slide, so that the positioning rod slides along the direction close to the steel bar group until it abuts against the end steel bar of the steel bar group. The precast wall panel is located on the side of the positioning rod close to the steel bar group, and the positioning rod is exposed.

[0029] S5: The second driving component drives the clamping component to slide horizontally, and the clamping component drives the precast wall panel to slide along the direction close to the positioning rod, and the end of the precast wall panel continuously approaches the positioning rod;

[0030] S6: The end of the precast wall panel passes through the guide surface, and the end of the insert rod will be in contact with the bottom surface of the precast wall. The elastic element is in a compressed state until the insert rod is inserted into the perforation at the very end of the precast wall panel.

[0031] S7: The third driving component drives the positioning rod to slide away from the precast wall panel;

[0032] S8: The second driving component causes the precast wall panel to retract a distance equal to the width of one insertion rod;

[0033] S9: The first driving component drives the mounting base to slide vertically, and the mounting base drives the precast wall panel to move downward, so that multiple steel bars are inserted into the corresponding holes.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. It can achieve precise alignment of the perforations on the precast wall panel with the corresponding steel bars, eliminating the need for construction workers to repeatedly move the precast wall panel for position adjustment. This reduces the effort required of construction workers in the alignment process of the precast wall panel and improves the installation efficiency of the precast wall panel.

[0036] 2. When the moving component drives the mounting frame to slide until the positioning rod abuts against the end of the reinforcing bar, the auxiliary support seat is driven to move downward through the telescopic component. The horizontal plate and the support plate move downward as a result until the horizontal plate contacts the ground at the construction area. The cooperation between the horizontal plate and the support plate provides auxiliary support for the mounting frame, improving the overall stability of the device and preventing the mounting frame from moving during the alignment of the precast wall panel. The reinforcing rod is used to improve the strength of the connection between the support plate and the horizontal plate, further improving the overall stability of the auxiliary support seat.

[0037] 3. When the precast wall panel is located between the first vertical plate and the second vertical plate, the side end of the precast wall panel abuts against multiple first adjusting bolts, and the plane containing the axis of the multiple first adjusting bolts is a vertical plane. This ensures that after the precast wall panel is clamped and fixed, it is in a vertical state, thereby preventing the precast wall panel from tilting and affecting the subsequent alignment work.

Detailed Implementation

[0044] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0045] Example 1

[0046] Embodiment 1 of this application discloses an installation device for prefabricated wall panels. (Refer to...) Figure 1 and Figure 2 The precast wall panel installation device includes a mounting frame 1, on which a moving component 11 is provided. The mounting frame 1 can slide horizontally via the moving component 11. A mounting seat 2 is slidably mounted on the mounting frame 1. A first driving member 8 is provided on the mounting frame 1 to drive the mounting seat 2 to slide vertically. A clamping member 12 is slidably mounted on the mounting seat 2 to clamp and fix the precast wall panel. A second driving member 9 is provided on the mounting seat 2 to drive the clamping member 12 to slide horizontally. A positioning seat 3 is provided on the mounting frame 1. A positioning rod 4 is slidably mounted on the positioning seat 3. A third driving member 10 is provided on the positioning seat 3 to drive the positioning rod 4 to slide horizontally. An insertion rod 5 is slidably connected to the end of the positioning rod 4. A guide surface 6 is provided at the end of the insertion rod 5. An elastic member 7 is provided inside the positioning rod 4 to abut against the insertion rod 5.

[0047] Reference Figure 1 and Figure 2The moving component 11 includes a moving wheel 111 mounted on the bottom of the mounting frame 1. The first driving component 8 includes a first telescopic rod 81 mounted on the mounting frame 1. The first telescopic rod 81 is an electrically controlled telescopic rod. The movable end of the first telescopic rod 81 is fixedly connected to the mounting base 2. The mounting base 2 is driven to slide vertically on the mounting frame 1 by the telescopic movement of the first telescopic rod 81.

[0048] Reference Figure 2 and Figure 3 The second driving component 9 includes two opposing side plates 92 fixed on the mounting base 2. A lead screw 93 is rotatably connected to each side plate 92. A drive motor 91 is mounted on one of the side plates 92. The output shaft of the drive motor 91 is coaxially and fixedly connected to the lead screw 93. A slider 94 is fixed on the lead screw thread of the lead screw 93. The rotation of the output shaft of the drive motor 91 drives the lead screw 93 to rotate, and the rotation of the lead screw 93 drives the slider 94 to slide horizontally.

[0049] Reference Figure 2 and Figure 3 The clamping member 12 includes a first vertical plate 121 and a second vertical plate 122 arranged in parallel and opposite directions. The first vertical plate 121 is fixedly connected to the slider 94. Two first adjusting bolts 23 and second adjusting bolts 24 are rotatably connected to the first vertical plate 121. The plane in which the axes of the two first adjusting bolts 23 lie is a vertical plane. The first adjusting bolts 23 and second adjusting bolts 24 are both slidably engaged with the second vertical plate 122. The second vertical plate 122 is provided with a waist-shaped hole 19 for the second adjusting bolts 24 to slide horizontally. When the precast wall panel is installed and fixed using the installation device, the precast wall panel is placed between the first vertical plate 121 and the second vertical plate 122. The second vertical plate 122 is slid so that it is in close contact with the precast wall panel. At this time, the side of the precast wall panel facing away from the second vertical plate 122 is in contact with the first vertical plate 121. The side end of the precast wall panel abuts against the two first adjusting bolts 23, and the plane containing the axis of the two first adjusting bolts 23 is a vertical plane. This ensures that after the precast wall panel is clamped and fixed, it is in a vertical state. Tightening the nuts of the first adjusting bolts 23 causes the first adjusting bolts to... The nut of 23 is pressed against the second vertical plate 122 to fix the position of the second vertical plate 122; then the second adjusting bolt 24 is slid in the waist-shaped hole 19 until the second adjusting bolt 24 abuts against the side end of the precast wall panel away from the first adjusting bolt 23, and then the nut of the second adjusting bolt 24 is tightened so that the nut of the second adjusting bolt 24 is pressed against the second vertical plate 122. At this time, the precast wall panel is clamped in the cavity formed by the first vertical plate 121, the second vertical plate 122, the first adjusting bolt 23 and the second adjusting bolt 24, thereby fixing the precast wall panel on the installation device.

[0050] Reference Figure 1 and Figure 4 The third driving component 10 includes a second telescopic rod 101 mounted on the mounting base 2. The second telescopic rod 101 is an electrically controlled telescopic rod. The second telescopic rod 101 is horizontally arranged. The fixed end of the second telescopic rod 101 is fixedly connected to the mounting frame 1, and the movable end is fixedly connected to the rod-shaped positioning seat 3. The positioning rod 4 includes a first vertical rod 41, a horizontal rod 42, and a second vertical rod 43. The first vertical rod 41 is fixedly connected to the positioning seat 3. One end of the horizontal rod 42 is fixedly connected to the first vertical rod 41, and the other end is fixedly connected to the second vertical rod 43. The first vertical rod 41 and the second vertical rod 43 are located on both sides of the horizontal rod 42. The insertion rod 5 is slidably connected to the second vertical rod 43 on the same axis. The elastic element 7 includes a spring 71 located inside the second vertical rod 43. One end of the spring 71 abuts against the second vertical rod 43, and the other end abuts against the insertion rod 5. A photosensitive sensor 13 is embedded on the second vertical rod 43. The photosensitive sensor 13 is electrically connected to the second telescopic rod 101. The insertion rod 5 can slide to block the photosensitive sensor 13.

[0051] The second telescopic rod 101 drives the first vertical rod 41 to slide horizontally. The first vertical rod 41 thereby drives the horizontal rod 42 and the second vertical rod 43 to slide. The second vertical rod 43 then slides in the direction close to the rebar group. When the first vertical rod 41 moves to abut against the end rebar, the sliding of the first vertical rod 41 in the same direction is restricted. At this time, the second vertical rod 43 is coaxial with the rebar and located directly above the rebar. As the screw 93 rotates, the precast wall panel slides along the direction close to the positioning rod 4. During this process, the insertion rod 5 on the second vertical rod 43 can be inserted into the perforation of the precast wall panel. When the insertion rod 5 is not inserted into the perforation, the end of the insertion rod 5 is in contact with the bottom surface of the precast wall panel, at which time the insertion rod 5 blocks the photosensitive sensor 13. When the insertion rod 5 is inserted into the perforation, the rebound of the spring 71 pushes the insertion rod 5 to slide, so that the photosensitive sensor 13 is exposed. At this time, the photosensitive sensor 13 transmits a signal, and the second telescopic rod 101 receives the signal. Then, it drives the insertion rod 5 to slide away from the precast wall panel. At this time, the perforation at the very end of the precast wall panel is located directly above the steel bar at the very end. The first telescopic rod 81 can then drive the mounting base 2 to slide vertically, so that multiple steel bars are inserted into the corresponding perforations.

[0052] Reference Figure 2 and Figure 5The mounting frame 1 is equipped with a telescopic component 14, which includes a third telescopic rod 141 mounted on the mounting frame 1. The third telescopic rod 141 is an electrically controlled telescopic rod, and is vertically arranged. A mating seat 142 is fixed to the movable end of the third telescopic rod 141, and the mating seat 142 is slidably engaged with the mounting frame 1. A support plate 15 is fixed to the mating seat 142, and is vertically arranged. A horizontal plate 16 is fixed to the end of the support plate 15, and a connecting seat 18 is bolted to the horizontal plate 16. 5 is also connected to a connecting seat 18 by bolts. A fixed rod 171 is hinged to one of the connecting seats 18, and an adjusting rod 172 is hinged to the other connecting seat 18. The adjusting rod 172 is located inside the fixed rod 171 and is slidably connected to the fixed rod 171 on the same axis. A plurality of first limiting holes 20 are evenly opened along the axial direction on the adjusting rod 172, and a second limiting hole 21 is opened on the fixed rod 171. The limiting element includes a limiting pin 22 passing through the second limiting hole 21, and the limiting pin 22 passing through any of the first limiting holes 20.

[0053] When the positioning rod 4 abuts against the end rebar of the rebar assembly, the telescopic movement of the third telescopic rod 141 drives the mating seat 142 to move downwards. The horizontal plate 16 and the support plate 15 move downwards as a result, until the horizontal plate 16 contacts the ground at the construction area. The cooperation of the horizontal plate 16 and the support plate 15 provides auxiliary support for the mounting frame 1. At this time, the fixing rod 171 and the adjusting rod 172 are located between the horizontal plate 16 and the support plate 15 to improve the connection strength between them. The fixing rod 171 slides coaxially within the adjusting rod 172, thereby changing the overall length of the reinforcing rod 17. After the precast wall panel is aligned, multiple rebars are inserted into their corresponding holes, thus completing the fixing of the precast wall panel. At this point, one connecting seat 18 can be removed and connected to the ground at the construction area, while another connecting seat 18 is connected to the precast wall panel. The reinforcing rod 17 then provides diagonal support to the precast wall panel.

[0054] The implementation principle of the precast wall panel installation device in Embodiment 1 of this application is as follows: When installing the precast wall panel, the precast wall panel is clamped and fixed to the mounting frame 1 by the first vertical plate 121 and the second vertical plate 122 on the mounting base 2. During the process of the crane lifting the precast wall panel, the mounting frame 1 moves together with the precast wall panel. When the precast wall panel moves to the construction area, the precast wall panel slowly descends until the moving wheel 111 contacts the ground at the construction area, and the positioning rod 4 is located at the end of the steel bar group composed of multiple steel bars. Subsequently, the rolling of the movable wheel 111 drives the mounting frame 1 to slide. The sliding of the mounting frame 1 drives the first vertical rod 41 to slide horizontally. The first vertical rod 41 thereby drives the horizontal rod 42 and the second vertical rod 43 to slide. The second vertical rod 43 then slides in the direction close to the rebar group. When the first vertical rod 41 moves to abut against the end rebar, the sliding of the first vertical rod 41 in the same direction is restricted. At this time, the second vertical rod 43 is coaxial with the rebar and located directly above the rebar. The mounting frame 1 is then fixed, and the precast wall panel is now located on the side of the positioning rod 4 close to the rebar group, so that the positioning rod 4 is exposed. Subsequently, the rotation of the drive motor 91 drives the first vertical plate 121 to slide horizontally. The first vertical plate 121 and the second vertical plate 122 drive the precast wall panel to slide along the direction close to the positioning rod 4. The end of the precast wall panel thus continuously approaches the insertion rod 5. During the continuous movement of the precast wall panel, the end of the precast wall panel will pass through the guide surface 6, causing the insertion rod 5 to slide on the second vertical rod 43. The end of the insertion rod 5 will be in contact with the bottom surface of the precast wall, at which time the spring 71 is in a compressed state. As the precast wall panel continues to move, the perforation at the very end of the precast wall panel will move to the insertion rod 5. At this time, the rebound of the spring 71 pushes the insertion rod 5 to move, so that the insertion rod 5 is inserted into the perforation at the very end. Then, the insertion rod 5 is driven by the second telescopic rod 101. The wall panel is slid away from the precast wall panel, at which point multiple perforations are located above the corresponding reinforcing bars. Subsequently, the first telescopic rod 81 drives the mounting base 2 to slide vertically. The sliding of the mounting base 2 causes the first vertical plate 121 and the second vertical plate 122 to slide, thereby moving the precast wall panel downwards. This allows multiple reinforcing bars to be inserted into the corresponding perforations, and the construction personnel can then carry out subsequent pouring and support operations to complete the installation of the precast wall panel. The cooperation of the various components in the above process can achieve precise alignment between the perforations on the precast wall panel and the corresponding reinforcing bars, eliminating the need for construction personnel to repeatedly move the precast wall panel for position adjustments. This reduces the effort required of construction personnel during the alignment process of the precast wall panel and improves the installation efficiency of the precast wall panel.

[0055] Example 2

[0056] Example 2 discloses a method for installing precast wall panels, using an installation device for precast wall panels as described in Example 1, including the following steps:

[0057] S1: Place the precast wall panel between the first vertical plate 121 and the second vertical plate 122. Slide the second vertical plate 122 so that the second vertical plate 122 is in close contact with the precast wall panel. At this time, the side of the precast wall panel away from the second vertical plate 122 is in contact with the first vertical plate 121. The side end of the precast wall panel abuts against the two first adjusting bolts 23. Tighten the nuts of the first adjusting bolts 23 so that the nuts of the first adjusting bolts 23 are in close contact with the second vertical plate 122, fixing the position of the second vertical plate 122. Then, slide the second adjusting bolt 24 in the slotted hole 19 until the second adjusting bolt 24 abuts against the side end of the precast wall panel away from the first adjusting bolt 23. Tighten the nuts of the second adjusting bolts 24 so that the nuts of the second adjusting bolts 24 are in close contact with the second vertical plate 122. The precast wall panel is clamped and fixed between the first vertical plate 121 and the second vertical plate 122.

[0058] S2: Lift the precast wall panel and move it to the construction area.

[0059] S3: The precast wall panel descends slowly, the moving wheel 111 contacts the ground at the construction area, and the insertion rod 5 is located at the end of the steel bar group composed of multiple steel bars;

[0060] S4: The rolling of the moving wheel 111 drives the mounting frame 1 to slide. The sliding of the mounting frame 1 drives the first vertical rod 41 to slide horizontally. The first vertical rod 41 drives the horizontal rod 42 and the second vertical rod 43 to slide. The second vertical rod 43 then slides in the direction close to the steel bar group. When the first vertical rod 41 moves to abut against the end steel bar, the sliding of the first vertical rod 41 in the same direction is restricted. At this time, the second vertical rod 43 is coaxial with the steel bar and located directly above the steel bar. The insertion rod 5 is also located directly above the end steel bar. The precast wall panel is located on the side of the positioning rod 4 close to the steel bar group, and the positioning rod 4 is exposed.

[0061] S5: The drive motor 91 operates, the lead screw 93 rotates and drives the slider 94 to slide horizontally, so that the first vertical plate 121 and the second vertical plate 122 drive the precast wall panel to slide along the direction close to the insertion rod 5, and the end of the precast wall panel continuously approaches the insertion rod 5.

[0062] S6: The end of the precast wall panel passes through the guide surface 6, and the end of the insert rod 5 will be in contact with the bottom surface of the precast wall. The spring 71 is in a compressed state, the photosensor 13 is blocked, and the precast wall panel continues to slide. When the end hole moves to the insert rod 5, the insert rod 5 is inserted into the end hole of the precast wall panel.

[0063] S7: The light sensor 13 is exposed, and the light sensor 13 transmits a signal, while the second telescopic rod 101 receives the signal and then drives the insertion rod 5 to slide away from the precast wall panel.

[0064] S8: The first telescopic rod 81 drives the mounting base 2 to slide vertically, and the mounting base 2 drives the precast wall panel to move downward, so that multiple steel bars are inserted into the corresponding holes respectively.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
