Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a method for constructing long steel structure exterior wall panels based on a cage-type hanging ladder. Background Technology

[0002] Steel structure factory buildings typically use profiled metal panels as the enclosure structure. For factory exterior walls with significant height, to reduce horizontal joints and ensure wall continuity, the exterior wall panels sometimes need to be installed vertically as a single panel. However, mechanical edge locking is difficult during single-panel installation, requiring manual edge locking. This necessitates providing working space for multiple workers at different vertical heights to perform edge locking during construction. If multiple aerial work platforms are used simultaneously, a large area is needed to accommodate them, and the operation places high demands on space availability, operator experience, and the precision of machinery operation. Furthermore, this approach suffers from drawbacks such as high cost, low efficiency, and significant safety risks.

[0003] In the prior art, Chinese patent application CN104179342A discloses a hanging cage for installing profiled steel sheets on the walls of a steel structure factory building and its construction method. The specific description is as follows: "The first and second uprights of the hanging cage are welded to a base plate; horizontal tie rods are welded to the first and second uprights; pulleys are hung on roof purlins or gutters; hemp ropes are hung on the pulleys; bamboo planks are laid on the horizontal tie rods; and the hanging cage is hung on the roof purlins or gutters. The construction method is as follows: [The text abruptly ends here, likely due to an incomplete sentence or missing information.] The hanging cage is hoisted onto the roof purlins or gutters; bamboo planks are laid on the horizontal tie rods according to the installation position of the profiled steel sheets; pulleys and hemp ropes are installed on the right side of the hanging cage; the profiled steel sheets are tied together, and the pulleys are activated to hoist the cage to near the installation position. Workers then install the profiled steel sheets one by one inside the hanging cage, moving to the next work area after completing one. This hanging cage is reusable and has the advantages of being safe and reliable, having low cost for profiled steel sheet installation, saving time, and increasing labor efficiency.

[0004] However, the above construction method mainly revolves around the installation of ordinary profiled steel sheets one by one. In scenarios where the exterior wall panels are vertical long panels and need to be interlocked with the already installed exterior wall panels, after the panels are hoisted to near the installation position by ropes or slings, they need to be further brought closer to the free interlocking edge of the already installed exterior wall panels to form the seam to be locked. If the slings enter the joint area with the long panels, it can easily affect the interlocking of the seam between the long panels to be installed and the already installed long panels and the manual locking of the edges; if the slings are released before the long panels have obtained temporary support, it can easily cause the long panels to swing, slide, or shift their posture. Summary of the Invention

[0005] The purpose of this invention is to provide a construction method for steel structure exterior wall long panels based on a cage-type hanging ladder, which can transform the exterior wall long panels from a free-suspension state to an inclined installation state with the lower end restricted and the outer side supported, and guide them to the wall installation position through an auxiliary support frame.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A construction method for long steel structure exterior wall panels based on a cage-type hanging ladder includes the following steps: S1. The cage-type hanging ladder is installed in the construction area of ​​the steel structure exterior wall. The cage-type hanging ladder is equipped with an auxiliary support frame, a lower adjustment component, a guide adjustment component and a limit component. The lower adjustment component and the guide adjustment component can be adjusted in the direction of approaching or moving away from the wall. The lower part of the auxiliary support frame is connected to the lower adjustment component, and the upper part of the auxiliary support frame is connected to the guide adjustment component. S2. Based on the current installation position of the exterior wall panel to be installed, move the cage-type hanging ladder so that the auxiliary support frame corresponds to the installation area of ​​the exterior wall panel to be installed. S3. Adjust the lower adjustment component to make the auxiliary support frame in an inclined support state; S4. The long exterior wall panel to be installed is hoisted to the wall construction area using external hoisting equipment, so that the lower end of the long exterior wall panel to be installed is restricted from horizontal sliding by the bottom limiting part, and the outer side of the long exterior wall panel to be installed is tilted and relies on the auxiliary support frame; the bottom limiting part is any one of the limiting component and the existing bottom limiting structure of the steel structure exterior wall. After the long exterior wall panel to be installed is in the tilted installation state, the external hoisting equipment is released and removed. S5. Adjust the guide adjustment component and keep or adjust the lower adjustment component to maintain the lower position of the auxiliary support frame, so that the auxiliary support frame pushes or guides the current exterior wall panel to be installed from the tilted installation state to the wall installation position. S6. Manually lock and interlock the seams between the currently installed and existing exterior wall panels after the conversion. S7. After completing the installation of the current exterior wall panel to be installed, move the cage-type hanging ladder to the installation position corresponding to the next exterior wall panel to be installed, and select the corresponding bottom limiting part according to the installation space of the next exterior wall panel to be installed. Repeat steps S2 to S6 until the steel structure exterior wall panel construction of the predetermined construction section is completed.

[0007] Using the above technical solution, after the long exterior wall panel to be installed is hoisted to the wall construction area, it is not directly installed under continuous suspension and manual traction. Instead, the lower end of the long exterior wall panel to be installed is first constrained by the bottom limiting part, and its outer side is tilted and relies on the auxiliary support frame. This changes the long exterior wall panel to be installed from a free suspension state to a tilted installation state with the lower end restricted and the outer side supported. In this state, the lower end position, the middle outward swing, and the upper posture of the long panel are all constrained to a certain extent, which can reduce the collision, scratching, or misalignment of the interlocking edges caused by the swinging, twisting, or outward bulging of the middle when the long panel approaches the wall or an already installed long exterior wall panel.

[0008] Furthermore, by cooperating with the lower adjustment component and the guide adjustment component to adjust the position of the auxiliary support frame, the auxiliary support frame can guide the long wall panel to be installed from its tilted installation state to its upright position on the wall. This process does not rely on construction workers continuously supporting and forcibly aligning the suspended long panel at different heights. Instead, the auxiliary support structure on the cage-type hanging ladder provides a temporary posture reference and a straightening path for the long panel, allowing it to stably approach the corresponding edge of the already installed long wall panel before entering the manual seaming process. Through this structure, the risk of shaking and collision during the installation of the long panel can be reduced, and a relatively stable alignment of the panel joints can be provided for subsequent manual seaming.

[0009] A further improvement of the technical solution of the present invention is that: in step S3, when the auxiliary support frame is in an inclined bearing state, the upper part of the auxiliary support frame is further away from the wall than its lower part.

[0010] The above technical solution enables the auxiliary support frame to provide tilted support for the long exterior wall panel to be installed on the outer side of the wall. When the long exterior wall panel to be installed is delivered into the wall construction area by external hoisting equipment, its lower end can be initially limited by the bottom limiting part, and its outer side can tilt against the auxiliary support frame. This transforms the long exterior wall panel from a completely suspended state to a tilted installation state with its lower end restricted and its outer side supported by auxiliary support. When a limiting component is used as the bottom limiting part, temporary limiting can be achieved by placing the limiting component in a limited state. This reduces the swaying, torsion, and outward deviation of the long panel during suspension in the air, providing initial support conditions for subsequent controlled straightening.

[0011] A further improvement of the technical solution of the present invention is as follows: In step S4, when there is a steel column, frame, wall base structure, bottom edge structure or edge of an already installed exterior wall panel that can abut or be adjacent to the lower end of the exterior wall panel to be installed and restrict its horizontal sliding at the installation location of the exterior wall panel to be installed, the existing bottom limiting structure of the steel structure exterior wall is selected as the bottom limiting part; when the installation location of the exterior wall panel to be installed lacks an existing bottom limiting structure, the limiting component is placed in a limiting state as the bottom limiting part.

[0012] By adopting the above technical solution, different bottom limiting methods can be selected according to different installation locations: for long exterior wall panels near steel columns, frames, or finishing areas, the existing on-site structure can be used to horizontally limit the bottom of the long panel, reducing interference between temporary limiting components and the finishing space; for locations lacking existing limiting structures, such as the middle of continuous walls, temporary limiting can be formed by unfolding the limiting components. Thus, the bottom limiting method can be adapted to different panel locations, avoiding the impact on the installation of edge panels, finishing panels, or column-supported panels due to the uniform arrangement of temporary bottom limiting components.

[0013] A further improvement of the technical solution of the present invention is that: in step S5, the lower adjustment component remains in the position after adjustment in step S3, and the guide adjustment component drives the upper part of the auxiliary support frame to move towards the wall, so that the auxiliary support frame uses the lower part as the support reference and the upper part as the guide end to push or guide the current external wall long plate to be installed to the wall installation position.

[0014] Using the above technical solution, with the current exterior wall panel to be installed already in a state where its lower end is limited by the bottom limiting part and its outer side is tilted and relies on the auxiliary support frame, the lower adjustment component no longer continues to retract or move outward, but instead serves as a relatively stable support base for the lower part of the auxiliary support frame. The guide adjustment component then drives the upper part of the auxiliary support frame to move closer to the wall surface, thereby allowing the auxiliary support frame to push or guide the current exterior wall panel to be installed to straighten by means of upper guidance and lower support. This avoids the disruption of the lower end limiting state of the long panel due to continued changes in the position of the lower part of the auxiliary support frame during the straightening process, reducing problems such as bottom retraction, lower end misalignment, or unstable straightening path, allowing the current exterior wall panel to be installed to enter the wall installation position from the tilted pre-installation state with a more stable path.

[0015] A further improvement of the technical solution of the present invention is that: the cage-type hanging ladder includes a base, a ladder frame extending along the height direction and fixedly connected to the top of the base, a cage protection frame disposed on the ladder frame, and a hanging part disposed at the upper end of the ladder frame; a lower adjustment component is disposed at the lower part of the ladder frame, a guide adjustment component is disposed at the upper part of the ladder frame, and an auxiliary support frame is disposed on the side of the ladder frame close to the wall. The lower part of the auxiliary support frame is connected to the ladder frame through the lower adjustment component, and the upper part of the auxiliary support frame is connected to the ladder frame through the guide adjustment component. The lower adjustment component and the guide adjustment component can respectively adjust the distance between the lower and upper parts of the auxiliary support frame and the wall.

[0016] Using the above technical solution, the lower and upper parts of the auxiliary support frame are connected to the ladder frame through a lower adjustment component and a guide adjustment component, respectively. This allows the auxiliary support frame to form controlled supports at both the upper and lower points along the height of the ladder frame, and to adjust the tilt angle and support position according to the hoisting status and installation position of the long exterior wall panel to be installed. Therefore, the cage-type hanging ladder can not only serve as a vertical working passage for construction workers, but also provide a posture control foundation during the transition of the long exterior wall panel from a suspended state to its wall installation position. This reduces the risk of swaying, twisting, and collision when the long panel approaches the wall or when already installed, and improves the alignment stability of the panel edges before manual edge locking.

[0017] A further improvement of the technical solution of the present invention is as follows: the lower adjustment component includes a jack one fixedly connected to the lower part of the ladder frame, the extension and retraction direction of the jack one being set along the direction of approaching or away from the wall, a transition block one fixedly connected to the side of the jack one away from the ladder frame, and a drive shaft one fixedly connected to both sides of the transition block one, the drive shaft one being rotatably connected to the bottom of the auxiliary support frame; the guide adjustment component includes a jack two fixedly connected to the upper part of the ladder frame, the extension and retraction direction of the jack two being set along the direction of approaching or away from the wall, a transition block two fixedly connected to the side of the jack two away from the ladder frame, and a drive shaft two fixedly connected to both sides of the transition block two, and strip grooves extending along the length direction of the auxiliary support frame are opened on both sides, the drive shaft two corresponding to and slidingly engaging with the strip grooves one by one.

[0018] By adopting the above technical solution, by setting jack one at the bottom of the ladder frame and rotatably connecting jack one to the bottom of the auxiliary support frame via adapter block one and drive shaft one, the lower part of the auxiliary support frame can form a hinged fulcrum that can be adjusted in the direction of approaching or moving away from the wall, thus facilitating the adjustment of the auxiliary support frame to an inclined support state before construction; by setting jack two at the top of the ladder frame and slidingly engaging jack two with the strip grooves on both sides of the auxiliary support frame via adapter block two and drive shaft two, the upper part of the auxiliary support frame can have a sliding margin when guided towards the wall, avoiding jamming of the auxiliary support frame due to simultaneous constraint of the upper and lower adjustment points. Thus, the auxiliary support frame can smoothly change its posture with the cooperation of the lower rotatable connection and the upper sliding guide, so as to tilt and guide the long exterior wall panel to be installed.

[0019] A further improvement of the technical solution of the present invention is that: the limiting component includes a fixing block fixedly connected to the top of the base, the fixing block has a threaded hole, an adjusting screw is threadedly connected in the threaded hole, one end of the adjusting screw is fixedly connected to a screw head, and the other end is rotatably connected to a baffle; the baffle can rotate relative to the adjusting screw to switch between a limiting posture for limiting the horizontal sliding of the lower end of the current exterior wall panel to be installed and an avoidance posture for avoiding the current exterior wall panel to be installed.

[0020] By employing the above technical solution, a fixing block is installed on the top of the base, and the adjusting screw engages with the threaded hole on the fixing block. Rotating the adjusting screw allows the baffle to move closer to or further away from the lower end of the exterior wall panel to be installed. When the installation location lacks an existing bottom limiting structure, the baffle can extend and function as a bottom limiting part to restrict the horizontal slippage of the lower end of the exterior wall panel during the straightening process. When the installation location has existing limiting structures such as steel columns, frames, or bottom edge trimming structures, the baffle can retract to avoid interfering with the placement, straightening, and edge locking of the exterior wall panel. This structure allows for a simpler threaded adjustment method to switch the bottom limiting part between the limiting and avoiding states, enhancing adaptability to different installation locations.

[0021] A further improvement of the technical solution of the present invention is that: multiple sets of directional wheels are arranged at intervals along the height direction on the side of the auxiliary support frame away from the ladder frame, the wheel surface of the directional wheels protrudes from the side of the auxiliary support frame away from the ladder frame, and each set of directional wheels includes two directional wheels arranged at intervals along the width direction of the auxiliary support frame. The directional wheels are used to make rolling contact with the outer side surface of the exterior wall panel to be installed.

[0022] By adopting the above technical solution, multiple sets of directional wheels are set along the height direction on the side of the auxiliary support frame away from the ladder frame. This allows the long exterior wall panel to be installed to receive rolling support at multiple height positions when it is tilted against the auxiliary support frame. During the process of the long exterior wall panel to be installed turning from the tilted installation state to the wall installation position, the directional wheels make rolling contact with the outer side of the panel. This reduces the frictional resistance and scratch risk between the outer side of the panel and the directional wheels, making the turning process smoother and improving the stability of the panel edge alignment before manual edge locking.

[0023] A further improvement of the technical solution of the present invention is that: multiple sets of guide blocks are fixedly connected to the side of the ladder frame near the auxiliary support frame, each set of guide blocks has two blocks, the two guide blocks are spaced apart along the width direction of the auxiliary support frame, and each set of guide blocks has a guide surface that expands outward toward the hoisting side of the exterior wall panel to be installed on the side that is close to each other; the guide surface is used to guide the outer side of the exterior wall panel to be installed into the rolling support position of multiple sets of directional wheels when the exterior wall panel to be installed approaches the auxiliary support frame from the hoisting state.

[0024] By adopting the above technical solution, by fixing the guide block to the ladder frame and making the two guide surfaces form an outward guide channel facing the side of the long wall panel to be installed, the outer side of the long panel can be pre-guided when the long panel approaches the auxiliary support frame from the hoisting state. This allows the long panel to gradually enter the rolling support position of multiple sets of directional wheels without directly and precisely touching the auxiliary support frame in a suspended swing state. Since the guide block is fixed to the ladder frame and does not move with the rotation of the auxiliary support frame, the guide block mainly plays a role in the hoisting and guiding stage. It is not easy for it to enter the long panel's rotation path or the wall installation position later, thus avoiding interference with the long panel's rotation and manual edge locking.

[0025] By adopting the above technical solution, the technical effects achieved by this invention compared to the prior art are as follows: 1. This invention first limits the lower end of the long exterior wall panel to be installed, then provides inclined support to its outer side, and guides it to be upright while in a supported state. This transforms the long exterior wall panel from a free-suspension state to a controlled support state during the hoisting and edge-locking process. This reduces the risk of swinging, twisting, collision, and misalignment of the panel when it is close to the wall or when it is already installed, and provides a relatively stable alignment state for the panel seams when manually locking the edges.

[0026] 2. This invention first places the long exterior wall panel to be installed in an installation state with the upper part tilted outward and the lower part restricted, and then gradually guides it from the upper part towards the wall surface to straighten it. This makes the straightening process of the long panel have a continuous posture change path, which can reduce the sudden posture changes caused by relying solely on manual support or local pushing, and reduce the situation of panel bottom offset, panel surface shaking and difficulty in aligning panel seams during the straightening process.

[0027] 3. The present invention selects the bottom limiting method according to the actual space of the installation position of the exterior wall long panel to be installed, so that different panel positions such as the middle panel, the column-side panel, the edge panel or the finishing panel can obtain the corresponding lower limit conditions, thereby avoiding interference with steel columns, edge structures or the edges of already installed panels when a temporary limiting method is uniformly adopted, and improving the adaptability of the construction process under different installation positions.

[0028] 4. In the process of the long board moving from the hoisting state to the supporting state, the outer side of the long board is pre-guided, so that the long board does not need to be directly and accurately attached to the supporting position in the suspended swing state. This reduces the dependence on manual traction and one-time alignment accuracy in the guiding stage, and reduces the risk of deflection, collision and scratch during the initial contact of the long board.

[0029] 5. In the process of tilting and guiding the long plate, the outer side of the long plate is supported and moved by rolling contact, which can reduce the frictional resistance between the long plate and the support part, reduce scratches, indentations or jamming on the plate surface, and make the action connection between the long plate from hoisting and introduction, tilting support to positioning before locking the edge more continuous.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the embodiments.

[0034] Example This invention provides a construction method for long steel structure exterior wall panels based on a cage-type hanging ladder, comprising the following steps: S1. The cage-type hanging ladder is installed in the construction area of ​​the steel structure exterior wall. The cage-type hanging ladder is equipped with an auxiliary support frame 401, a lower adjustment component 2, a guide adjustment component 3 and a limiting component 5. The lower adjustment component 2 and the guide adjustment component 3 can be adjusted in the direction of approaching or moving away from the wall. The lower part of the auxiliary support frame 401 is connected to the lower adjustment component 2, and the upper part of the auxiliary support frame 401 is connected to the guide adjustment component 3. S2. Based on the current installation position of the exterior wall panel to be installed, move the cage-type hanging ladder so that the auxiliary support frame 401 corresponds to the installation area of ​​the exterior wall panel to be installed. S3. Adjust the lower adjustment component 2 so that the auxiliary support frame 401 is in an inclined support state; S4. The long wall panel to be installed is hoisted to the wall construction area by external hoisting equipment, so that the lower end of the long wall panel to be installed is restricted from horizontal sliding by the bottom limiting part, and the outer side of the long wall panel to be installed is tilted and relies on the auxiliary support frame 401; the bottom limiting part is either the limiting component 5 or the existing bottom limiting structure of the steel structure wall. After the long wall panel to be installed is in the tilted installation state, the external hoisting equipment is released and removed. S5. Adjust the guide adjustment component 3, and keep or cooperate with the lower adjustment component 2 to adjust the lower position of the auxiliary support frame 401, so that the auxiliary support frame 401 pushes or guides the current exterior wall long plate to be installed from the inclined installation state to the wall installation position. S6. Manually lock and interlock the seams between the currently installed and existing exterior wall panels after the conversion. S7. After completing the installation of the current exterior wall panel to be installed, move the cage-type hanging ladder to the installation position corresponding to the next exterior wall panel to be installed, and select the corresponding bottom limiting part according to the installation space of the next exterior wall panel to be installed. Repeat steps S2 to S6 until the steel structure exterior wall panel construction of the predetermined construction section is completed.

[0035] Preferably, the steel structure exterior wall long panel is a profiled metal exterior wall panel installed vertically along the wall. Before construction, the installation area of ​​the exterior wall long panel to be installed is determined according to the layout drawing, wall installation benchmark, the position of the already installed exterior wall long panel and the column spacing of the steel structure exterior wall. The cage-type hanging ladder is arranged along the height direction of the steel structure exterior wall. Its upper part is hung on the parapet waler, upper purlin or other stable steel components on the upper part of the steel structure exterior wall, and its lower part is supported on the ground or a temporary support position. It can be moved or adjusted according to the installation position of the exterior wall long panel to be installed.

[0036] Preferably, during construction, the cage-type hanging ladder is first moved according to the installation position of the exterior wall panel to be installed, so that the auxiliary support frame 401 corresponds to the installation area of ​​the exterior wall panel to be installed; then the lower adjustment component 2 is adjusted so that the auxiliary support frame 401 is in an inclined support state. The inclined support state means that the auxiliary support frame 401 is arranged at an inclination relative to the wall installation plane and can be tilted and supported by the outer side of the exterior wall panel to be installed.

[0037] During operation, the long exterior wall panel to be installed is hoisted to the wall construction area using external hoisting equipment. During the hoisting process, the lower end of the long exterior wall panel to be installed is brought close to the bottom limiting part, and the lower end is restricted from horizontal sliding by the bottom limiting part. The bottom limiting part is mainly used to limit the position of the lower end of the long exterior wall panel to be installed, and is not necessary to raise the long exterior wall panel to be installed. The bottom limiting part can be the existing bottom limiting structure of the steel structure exterior wall, or it can be the limiting component 5. The existing bottom limiting structure can be a steel column, wall base structure, bottom edge structure, frame, edge of an already installed exterior wall panel, or other structure that can restrict the horizontal sliding of the lower end of the exterior wall panel to be installed. The limiting component 5 can be set as an active limiting structure with a limiting state and an avoidance state. When there is no available existing bottom limiting structure at the installation location, the limiting component 5 is in the limiting state to horizontally limit the lower end of the exterior wall panel to be installed. When there is an existing limiting structure such as a steel column, frame, or wall base structure at the installation location, the limiting component 5 is in the avoidance state to avoid interfering with the entry of the exterior wall panel to be installed into the installation area.

[0038] After the lower end of the current exterior wall panel to be installed is limited by the bottom limiting part, the outer side of the current exterior wall panel to be installed is tilted and relies on the auxiliary support frame 401. At this time, the current exterior wall panel to be installed no longer completely relies on the external hoisting equipment to maintain its posture in the air, but forms an inclined installation state with the lower end limited by the bottom limiting part and the outer side assisted by the auxiliary support frame 401. According to the construction needs, the external hoisting equipment can continue to retain the anti-fall connection to cooperate with the subsequent straightening operation.

[0039] Subsequently, the guide adjustment component 3 is adjusted, and the lower adjustment component 2 is kept in place or adjusted in coordination with the lower position of the auxiliary support frame 401. Specifically, the guide adjustment component 3 can drive or restrict the upper part of the auxiliary support frame 401 to move toward the wall mounting plane, and the lower adjustment component 2 can keep the lower support reference of the auxiliary support frame 401 or adjust its distance relative to the wall, so that the auxiliary support frame 401 forms a guiding and straightening effect on the exterior wall panel to be installed from top to bottom. Under this guiding and straightening effect, the exterior wall panel to be installed gradually changes from an inclined installation state to the wall installation position.

[0040] The wall installation position refers to the position where the interlocking edge of the exterior wall panel to be installed can be engaged with the corresponding edge of the already installed exterior wall panel for joint interlocking or manual locking. During the straightening process, the lower end of the exterior wall panel to be installed is restricted by the bottom limiting part, making it less likely to slide horizontally. The middle and upper parts of the exterior wall panel to be installed are controlled to approach the wall installation plane under the action of the auxiliary support frame 401, thereby reducing the situation of the panel swinging freely, twisting, and impacting the already installed exterior wall panel.

[0041] Preferably, in step S3, when the auxiliary support frame 401 is in an inclined receiving state, the upper part of the auxiliary support frame 401 is further away from the wall than its lower part.

[0042] During construction, external hoisting equipment lifts the long exterior wall panel to be installed to the wall construction area. The lower end of the panel is first positioned near the bottom limiting part, which restricts its horizontal sliding. Then, the outer side of the panel is tilted against the auxiliary support frame 401. Since the upper part of the auxiliary support frame 401 is further away from the wall than its lower part, the panel can lean against it with its lower end as a relative reference and its upper part tilted outward, thus forming a relatively stable tilted installation state. In this state, the panel no longer completely relies on the external hoisting equipment to maintain its posture in the air. External hoisting equipment that has entered or may enter the panel joint work area can be released or removed. The swing amplitude of the middle and upper parts of the panel can be limited by the auxiliary support frame 401, which is beneficial for subsequent straightening operations.

[0043] Preferably, in step S4, when the installation location of the exterior wall panel to be installed has a steel column, frame, wall base structure, bottom edge structure, or edge of an already installed exterior wall panel that can abut against or be adjacent to the lower end of the exterior wall panel to be installed and restrict its horizontal sliding, the existing bottom limiting structure of the steel structure exterior wall is selected as the bottom limiting part; when the installation location of the exterior wall panel to be installed lacks an existing bottom limiting structure, the limiting component 5 is placed in a limiting state as the bottom limiting part.

[0044] In this embodiment, the bottom limiting part is selected based on the actual space of the installation location of the exterior wall panel to be installed. When the exterior wall panel to be installed is close to a steel column, frame, wall base structure, bottom edge structure, edge of an already installed exterior wall panel, or other existing structure that can restrict the horizontal sliding of the lower end of the panel, the existing structure can be used as the bottom limiting part, so that the lower end of the exterior wall panel to be installed is directly restricted by the existing structure during the straightening process. At this time, the limiting component 5 can be in an avoidance state to prevent it from entering the finishing area or the column area and interfering with the placement and straightening of the exterior wall panel to be installed.

[0045] When the long exterior wall panel to be installed is located in the middle of a continuous wall surface, and there is no existing bottom limiting structure available at its installation location, the limiting component 5 can be switched from the avoidance state to the limiting state, so that the limiting component 5 acts as a bottom limiting part to restrict the lower end of the long exterior wall panel to be installed from sliding horizontally. The above two limiting methods can be selected according to the panel position, so that the construction method can be adapted to different installation situations such as middle panels, edge panels, and finishing panels.

[0046] Preferably, in step S5, the lower adjustment component 2 remains in the position adjusted in step S3, and the guide adjustment component 3 drives the upper part of the auxiliary support frame 401 to move closer to the wall, so that the auxiliary support frame 401 uses the lower part as the support reference and the upper part as the guide end to push or guide the current external wall long plate to be installed to the wall installation position.

[0047] During construction, the lower adjustment component 2 is kept in the position adjusted in step S3 so that the lower part of the auxiliary support frame 401 remains relatively stable during the straightening process of the current exterior wall panel to be installed. Then, the guide adjustment component 3 is adjusted so that the guide adjustment component 3 drives the upper part of the auxiliary support frame 401 to move closer to the wall. When the upper part of the auxiliary support frame 401 moves, it applies a guiding action towards the wall installation position to the current exterior wall panel that is tilted against the auxiliary support frame 401. Since the lower part of the auxiliary support frame 401 is kept in a relatively fixed position by the lower adjustment component 2, the auxiliary support frame 401 can use the lower part as the support reference and the upper part as the guide end to drive or guide the current exterior wall panel to be installed from the tilted installation state to gradually straighten.

[0048] During the straightening process of the exterior wall panel to be installed, its lower end is continuously limited by the horizontal restraint of the bottom limiting part. The lower part of the auxiliary support frame 401 does not continue to retract or move away from the wall with the lower adjustment component 2. Therefore, the lower end of the exterior wall panel to be installed is not prone to horizontal displacement due to changes in the position of the lower part of the auxiliary support frame 401. At the same time, the upper part of the auxiliary support frame 401 moves closer to the wall installation plane under the action of the guide adjustment component 3, so that the upper part of the exterior wall panel to be installed first gains a guiding tendency towards the wall, and then the middle and lower parts of the panel gradually straighten with its overall posture. After the exterior wall panel to be installed is straightened to the wall installation position, its interlocking edge is in a position where it can be manually locked with the corresponding edge of the already installed exterior wall panel. Construction workers can then manually lock the edges on the cage-type hanging ladder.

[0049] like Figures 1-6 As shown, preferably, the cage-type hanging ladder includes a base 101, a ladder frame 102 extending along the height direction and fixedly connected to the top of the base 101, a cage protection frame 103 disposed on the ladder frame 102, and a hanging part 104 disposed at the upper end of the ladder frame 102; a lower adjustment component 2 is disposed at the lower part of the ladder frame 102, a guide adjustment component 3 is disposed at the upper part of the ladder frame 102, and an auxiliary support frame 401 is disposed on the side of the ladder frame 102 near the wall. The lower part of the auxiliary support frame 401 is connected to the ladder frame 102 through the lower adjustment component 2, and the upper part of the auxiliary support frame 401 is connected to the ladder frame 102 through the guide adjustment component 3. The lower adjustment component 2 and the guide adjustment component 3 can respectively adjust the distance between the lower and upper parts of the auxiliary support frame 401 and the wall.

[0050] In this embodiment, the base 101 is disposed at the lower end of the ladder frame 102 to support the lower part of the ladder frame 102; the ladder frame 102 extends along the height direction and is fixedly connected to the top of the base 101. The ladder frame 102 may include two main beams extending along the height direction and several steps connected between the two main beams. Construction personnel can move up and down along the ladder frame 102 to reach different height positions of the exterior wall panel to be installed for observation, straightening, pressing, or manual edge locking operations; the protective cage frame 103 is disposed on the outside of the ladder frame 102 to protect construction personnel from the outside direction when going up and down the ladder frame 102 or during work stoppages; the hanging part 104 is disposed at the upper end of the ladder frame 102 to hang the protective cage-type ladder on the parapet wall waler, upper purlin, or other stable steel structure components on the upper part of the steel structure exterior wall, so that the protective cage-type ladder can be arranged along the height direction of the steel structure exterior wall.

[0051] like Figures 3-6As shown, preferably, the lower adjustment assembly 2 includes a jack 201 fixedly connected to the lower part of the ladder frame 102. The extension and retraction direction of the jack 201 is set along the direction close to or away from the wall. A transition block 202 is fixedly connected to the side of the jack 201 away from the ladder frame 102. A drive shaft 203 is fixedly connected to both sides of the transition block 202. The drive shaft 203 is rotatably connected to the bottom of the auxiliary support frame 401. The guide adjustment assembly 3 includes a jack 201 fixedly connected to the ladder frame 102. The upper part of the frame 102 has a second jack 301. The extension and retraction direction of the second jack 301 is set along the direction of approaching or away from the wall. The side of the second jack 301 away from the ladder frame 102 is fixedly connected to a second adapter block 302. Both sides of the second adapter block 302 are fixedly connected to a second drive shaft 303. Both sides of the auxiliary support frame 401 are provided with strip grooves 304 extending along the length direction of the auxiliary support frame 401. The second drive shaft 303 corresponds to the strip groove 304 and slides in fit.

[0052] During construction, in step S3, jack 201 extends or retracts to adjust the distance between the lower part of auxiliary support frame 401 and the wall, making the upper part of auxiliary support frame 401 further away from the wall relative to its lower part, thus placing auxiliary support frame 401 in an inclined support state. After the long exterior wall panel to be installed is hoisted to the wall construction area, its lower end is limited by the bottom limiting part, and its outer side leans against the auxiliary support frame 401, changing the long panel from a free-suspension state to an inclined installation state with the lower end restricted and the outer side supported by auxiliary support.

[0053] In step S5, jack 201 maintains its position adjusted in step S3, creating a relatively stable support reference for the lower part of the auxiliary support frame 401. Then, jack 301 is adjusted so that it drives the upper part of the auxiliary support frame 401 towards the wall via adapter block 302 and drive shaft 303. Because drive shaft 303 slides into the slots 304 on both sides of the auxiliary support frame 401, it slides relative to the wall as the upper part moves towards it. This releases the length and angle constraints of the auxiliary support frame 401 during its attitude change, preventing jamming due to the simultaneous restriction of its lower rotational connection and upper guide connection. Thus, the auxiliary support frame 401 can use its lower part as a support reference and its upper part as a guide to push or guide the currently installed exterior wall panel from its tilted pre-installation state to its wall installation position.

[0054] Preferably, jack 201 and jack 301 are screw jacks, mechanically locking hydraulic jacks, or other telescopic adjustment components that can maintain their telescopic positions after adjustment; when the auxiliary support frame is in an inclined receiving state or a guide turning state, jack 201 and jack 301 remain in a locked state.

[0055] like Figure 3 and Figure 4 As shown, preferably, the limiting component 5 includes a fixing block 501 fixedly connected to the top of the base 101. The fixing block 501 has a threaded hole, and an adjusting screw 502 is threadedly connected inside the threaded hole. One end of the adjusting screw 502 is fixedly connected to a screw head, and the other end is rotatably connected to a baffle 503. The baffle 503 can rotate relative to the adjusting screw 502 to switch between a limiting posture for limiting the horizontal sliding of the lower end of the current exterior wall panel to be installed and an avoidance posture for avoiding the current exterior wall panel to be installed.

[0056] During the work process, when the installation location of the exterior wall panel to be installed lacks steel columns, frames, wall base structures, bottom edge finishing structures, or existing bottom limiting structures such as the edge of an already installed exterior wall panel, the construction worker rotates the screw head, causing the adjusting screw 502 to drive the baffle 503 to extend towards the lower end of the exterior wall panel to be installed, and rotates the baffle 503 to make it horizontal, at which point the baffle 503 is in a limiting posture; after the exterior wall panel to be installed is hoisted to the wall construction area, its lower end can abut against or be adjacent to the baffle 503, blocking... Plate 503 is used to limit the horizontal slippage of the lower end of the exterior wall panel to be installed during the straightening process, so that the exterior wall panel to be installed can lean against the auxiliary support frame 401 with the lower end restricted. After the long panel is installed, the baffle 503 is rotated to a vertical position (avoidance posture), and then the adjusting screw 502 is rotated to make the adjusting screw 502 drive the baffle 503 to retract and keep the baffle 503 in an avoidance posture, thereby preventing the baffle 503 from being blocked by the installed exterior wall panel, wall foot structure or bottom edge structure.

[0057] When the installation location of the exterior wall panel to be installed has existing bottom limiting structures such as steel columns, frames, wall base structures, bottom edge finishing structures, or the edge of an already installed exterior wall panel, the screw head can be rotated first to cause the adjusting screw 502 to drive the baffle 503 to retract away from the lower end of the exterior wall panel to be installed, thus putting the baffle 503 in a avoidance state. At this time, the lower end of the exterior wall panel to be installed is limited by the existing bottom limiting structure, and the baffle 503 no longer extends into the lower installation space of the exterior wall panel to be installed, thereby avoiding the baffle 503 interfering with the hoisting, tilting, straightening, and subsequent manual edge-locking operations of the exterior wall panel to be installed.

[0058] like Figure 1 , Figure 2 and Figure 3As shown, preferably, the auxiliary support frame 401 is provided with multiple sets of directional wheels 402 at intervals along the height direction on the side away from the ladder frame 102. The wheel surface of the directional wheel 402 protrudes from the side of the auxiliary support frame 401 away from the ladder frame 102. Each set of directional wheels 402 includes two directional wheels 402 at intervals along the width direction of the auxiliary support frame 401. The directional wheels 402 are used to make rolling contact with the outer side of the exterior wall panel to be installed.

[0059] During operation, when the guide adjustment component 3 moves the upper part of the auxiliary support frame 401 closer to the wall, the auxiliary support frame 401, through multiple sets of directional wheels 402, pushes or guides the exterior wall panel to be installed from an inclined installation state to a straight installation position on the wall. When the exterior wall panel to be installed changes posture relative to the auxiliary support frame 401, the directional wheels 402 can rotate around their own axes, forming a rolling contact between the outer side of the exterior wall panel to be installed and the directional wheels 402. This reduces the frictional resistance between the outer side of the exterior wall panel to be installed and the directional wheels 402, minimizing scratches, indentations, or jamming on the panel surface, and making the straightening process of the exterior wall panel to be installed smoother.

[0060] Two of the directional wheels 402 in each set are respectively positioned on both sides of the auxiliary support frame 401 in the width direction to support the two sides of the outer side of the exterior wall panel to be installed. Each directional wheel 402 can be a rubber-coated wheel, a nylon wheel, or a roller with a flexible outer layer to reduce wear when in contact with the surface of the exterior wall panel to be installed. Through the above arrangement, the auxiliary support frame 401 can form multi-point, rolling support during the tilting and guiding of the exterior wall panel to be installed, which helps to improve the stability of the panel straightening process and provides a more stable edge alignment state for subsequent manual edge locking.

[0061] like Figure 3 and Figure 4 As shown, preferably, multiple sets of guide blocks 6 are fixedly connected to the side of the ladder frame 102 near the auxiliary support frame 401. Each set of guide blocks 6 has two blocks, and the two guide blocks 6 are spaced apart along the width direction of the auxiliary support frame 401. Each set of guide blocks 6 has a guide surface 7 that expands outward toward the hoisting side of the exterior wall panel to be installed on the side that is close to each other. The guide surface 7 is used to guide the outer side of the exterior wall panel to be installed into the rolling support position of the multiple sets of directional wheels 402 when the exterior wall panel to be installed approaches the auxiliary support frame 401 from the hoisting state.

[0062] During actual construction, the long exterior wall panel to be installed is hoisted to the wall construction area by external hoisting equipment. Since the panel is suspended, its outer surface may deviate slightly from the rolling support position of the multiple sets of directional wheels 402. At this time, the guide surface 7 of the guide block 6 first contacts the outer surface of the long exterior wall panel to be installed, guiding it and causing the outer surface of the panel to gradually enter the rolling support position of the multiple sets of directional wheels 402 along the guide surface 7. Once the long exterior wall panel to be installed has tilted against the auxiliary support frame 401, the guide block 6 no longer participates in the subsequent straightening action with the auxiliary support frame 401, but remains fixed relative to the ladder frame 102.

[0063] By fixing the guide block 6 to the ladder frame 102 instead of the auxiliary support frame 401, the guide block 6 can only play a guiding role during the long board hoisting and introduction stage. When the auxiliary support frame 401 is pushed or guided by the guide adjustment component 3 to straighten the current exterior wall long board to be installed, the guide block 6 will not move synchronously with the auxiliary support frame 401, thereby reducing the possibility of the guide block 6 entering the long board straightening path or the wall installation position, and avoiding interference of the guide structure with the subsequent straightening, fitting and manual edge locking.

[0064] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
