Description

Technical Field

[0001] This utility model relates to the field of building protection technology, and in particular to a temporary suspension structure for high-altitude operations in construction projects. Background Technology

[0002] Working at heights is a common practice in construction, exterior wall maintenance, and equipment installation, primarily involving operations at heights such as building rooftops and elevated platforms. Due to the inherent risk of falls in these environments, temporary suspended structures serve as the foundation for the support and protection of workers. Their stability and safety are directly related to the lives of the workers and are therefore a core element that must be prioritized in working at heights.

[0003] Currently, most temporary suspension structures on the market are fixed to building edges (such as parapet walls, tops of exterior wall panels, etc.) in the following ways: using simple clips, single-set bolt fastening, or heavy loads to fix the positioning components of the suspension device to the building edge; then connecting the work platform via suspension rods for operators to stand on. However, this type of structure has many safety hazards in practical applications and cannot meet the stringent requirements of high-altitude operations. The main problems are as follows:

[0004] Insufficient reliability: The clamping components in existing structures are simply designed, mostly using single-sided or single-set clamping plates, making it difficult to adapt to building edge structures of varying thicknesses (such as parapet walls with significant thickness differences). During clamping, uneven force can easily lead to loosening, especially under external forces such as wind impact or personnel movement, which may cause positioning components to shift or even fall off, directly threatening operational safety.

[0005] Poor adaptability: The clamping positions of traditional suspension structures are mostly fixed or have a limited range of adjustment, making it impossible to flexibly adjust the clamping spacing according to the actual thickness of the building's edge structure, resulting in poor adaptability.

[0006] Insufficient structural rigidity and stability: The connection between the positioning plate and the suspension rod of some temporary suspension structures lacks reinforcement design. When the weight of the suspended work platform and personnel is on the ground, the connection is prone to deformation due to stress concentration. At the same time, the lack of auxiliary support structure results in weak overall anti-tilting ability. Under dynamic loads (such as personnel movement), the whole structure is prone to swaying, further reducing stability.

[0007] Therefore, in view of the shortcomings of existing temporary suspension structures in terms of fixing reliability, adjustment adaptability, structural stability and locking and anti-loosening, there is an urgent need to design a new type of temporary suspension structure for high-altitude operations in construction engineering, which can achieve firm fixation of building edge structures of different thicknesses, ensure stability and safety during operation, and provide reliable safety protection for high-altitude workers. Utility Model Content

[0008] The purpose of this utility model is to provide a temporary suspension structure for high-altitude operations in construction engineering, so as to solve the problems existing in the prior art. It can achieve firm fixation of building edge structures of different thicknesses, ensure stability and safety during the operation, and provide reliable safety protection for high-altitude workers.

[0009] To achieve the above objectives, this utility model provides the following solution: a temporary suspension structure for high-altitude operations in construction engineering, comprising:

[0010] The positioning plate has an installation component at one end, and a suspension rod is connected to the installation component; a working platform can also be detachably connected to the suspension rod; the positioning plate is equipped with a positioning adjustment mechanism for clamping building components.

[0011] The positioning adjustment mechanism includes:

[0012] A sliding component is slidably mounted on the positioning plate, and a clamping plate is fixedly connected to the bottom of the sliding component;

[0013] A positioning ring, which is fixedly disposed on the top of the sliding member;

[0014] The adjustment assembly includes a support frame mounted on a positioning plate and an adjustment rod passing through the support frame. The positioning ring is sleeved on the adjustment rod and slides with the adjustment rod. The adjustment rod is provided with a locking assembly for locking the positioning ring.

[0015] In one embodiment, the mounting component includes an end mounting cylinder fixedly disposed on the positioning plate, the suspension rod is a first screw with external threads on its outer circumferential surface, the suspension rod passes through the mounting cylinder, and a first nut is threadedly connected to both sides of the suspension rod located on the mounting cylinder.

[0016] In one embodiment, the sliding component includes a sliding box with a U-shaped frame structure. The sliding box is fitted onto the positioning plate and slides in cooperation with the positioning plate. The clamping plate is fixedly connected to the bottom of the sliding box, and the positioning ring is fixedly disposed on the top of the sliding box.

[0017] As one embodiment, anti-slip rubber blocks are installed on the inner side wall of the clamping plate. The anti-slip rubber blocks are detachably connected to the clamping plate by bolts, and anti-slip textures are formed on the inner side of the anti-slip rubber blocks.

[0018] As one embodiment, the adjusting rod is a second screw with external threads on its outer circumference, and a second nut is provided on both sides of each set of positioning rings, the second nut being threadedly connected to the adjusting rod.

[0019] As one embodiment, the adjustment assembly further includes an auxiliary support structure, which includes an adjustment cover and a support rod. The adjustment cover is fixedly installed on the outer side wall of the clamping plate, one end of the support rod is connected to the adjustment cover, and the other end of the support rod is hinged to the positioning plate via a pin.

[0020] As one embodiment, the sidewall of the adjusting cover is provided with at least two sets of positioning holes spaced apart along its length, and the sidewall of the support rod away from the positioning plate is provided with a through hole adapted to the positioning hole. The support rod and the adjusting cover are fixedly connected by positioning pins inserted into the positioning hole and the through hole.

[0021] In one embodiment, the work platform includes a suspended platform, which includes a base plate, a front baffle vertically fixed to the front end of the base plate, a rear fixing plate vertically fixed to the rear end of the base plate, and side guardrails connecting the front baffle and the rear fixing plate on both sides; the rear fixing plate of the suspended platform is fixedly connected to the suspension rod.

[0022] As one embodiment, the end of the suspension rod away from the positioning plate is provided with a connector, the outer side of the connector is machined with an installation plane, the rear fixing plate of the basket is provided with a through hole at the corresponding position, and the rear fixing plate is fixedly connected to the installation plane of the connector by bolts.

[0023] In one embodiment, a reinforcing rod is fixedly connected to the positioning plate; one end of the reinforcing rod is fixedly connected to the side wall of the positioning plate; and the other end of the reinforcing rod is fixedly connected to the outer wall of the mounting cylinder.

[0024] The utility model achieves the following technical effects compared to the prior art:

[0025] 1. This structure boasts excellent adaptability and reliable fixation, flexibly adapting to building edge structures of varying thicknesses. By sliding the sliding member along the length of the positioning plate, the clamping plate can precisely conform to the side of the building edge structure. The gap between the positioning ring and the adjusting rod allows for flexible position adjustment. The locking assembly of the adjusting component, with locking elements on both sides of the positioning ring for secure clamping, firmly locks the sliding member and clamping plate, ensuring stable fixation of the positioning plate and preventing loosening or displacement, effectively adapting to diverse building edge structures.

[0026] Meanwhile, this structure is easy to operate and highly safe, facilitating flexible adjustment and relocation of the work position. Installation and disassembly can be quickly completed via the detachable work platform and suspension rod; when changing the work position, simply loosen the locking components and slide to release the clamp to move the positioning plate, then repeat the operation to fix the work in place – a simple and efficient process. The bottom support of the positioning plate and multiple locking confirmation steps further ensure the stability of high-altitude operations, providing reliable safety for operators.

[0027] Other technical solutions of this utility model have also achieved the following technical effects:

[0028] 2. In the technical solution of this application, after the positioning plate is stably placed on the top of the parapet wall, the bottom clamping plate can be moved synchronously by two sets of slides on the sliding positioning adjustment mechanism. Anti-slip rubber blocks are pasted on the inner side of the clamping plate to ensure effective friction when it is in close contact with both sides of the parapet wall. Four sets of second nuts connected to the adjusting rod (second screw) are distributed equidistantly along the axis. Two sets of nuts are arranged on each side of each positioning ring. By symmetrically tightening, the end face of the nut is tightly abutted against the positioning ring, forming a bidirectional clamping force. This design, through the rigid constraint of the slide box and the axial locking of the nuts, makes the clamping force of the clamping plate on the parapet wall evenly distributed, effectively preventing the positioning plate from shifting laterally or loosening, and significantly improving the safety redundancy of the suspended platform operation.

[0029] 3. A high-strength steel support rod is hinged to the end of the positioning plate away from the mounting cylinder via a pin. An adjustment cover is vertically welded to the outer wall of the outer clamping plate. Multiple sets of positioning holes are spaced along the length of the side wall of the adjustment cover, and corresponding through holes are opened at the free end of the support rod. The two are quickly connected by positioning pins. After the two sets of clamping plates clamp the parapet wall, the support rod is rotated and embedded into the adjustment cover. The positioning pin is inserted into the appropriate hole, so that the support rod, the outer clamping plate, and the positioning plate form a stable right-angled triangular support structure. This design can transfer the radial force borne by the outer clamping plate to the positioning plate through the support rod. Combined with the friction of the anti-slip rubber block, the overall anti-overturning ability of the device is improved, further enhancing the structural stability and operational safety of high-altitude operations.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] This embodiment provides a temporary suspension structure for high-altitude operations in construction engineering, including a positioning plate 1. An installation component is provided at the end of the positioning plate 1, which is used to connect suspension components. A positioning adjustment mechanism is also provided on the positioning plate 1 to clamp the building components. Simultaneously, the bottom surface of the positioning plate 1 can serve as an abutment surface, supporting the end face of the building components (such as the top of a parapet wall, the top of an exterior wall panel, etc.), providing basic support for the overall structure. The suspension components include a suspension rod 2 and a working platform. The suspension rod 2 is connected to the installation component of the positioning plate 1. The working platform can also be detachably connected to the suspension rod 2; preferably, the working platform is detachably connected to the end of the suspension rod 2 away from the positioning plate 1. The working platform is used for operators to stand and work, and the edges of the working platform are preferably equipped with protective railings to improve operational safety.

[0037] The positioning and adjustment mechanism is used to clamp the building edge structure to fix the positioning plate 1 at the building edge. The mechanism includes a sliding member, a clamping plate 6, a positioning ring 3, and an adjustment assembly. The sliding member is slidably mounted on the positioning plate 1. Preferably, the sliding member can slide along the length direction of the positioning plate 1 (i.e., parallel to the thickness direction of the building edge structure) to adjust its position relative to the building edge structure, accommodating building edge structures of different thicknesses. The clamping plate 6 is fixedly connected to the bottom of the sliding member, with its clamping surface facing the building edge structure, for contact with the side of the building edge structure. The clamping of the building edge structure is achieved by adjusting the position of the sliding member. The positioning ring 3 is fixedly disposed on the top of the sliding member to cooperate with the adjustment assembly to lock the position of the sliding member.

[0038] The adjustment assembly includes a support frame 4, an adjustment rod 5, and a locking assembly. The support frame 4 is fixedly mounted on the positioning plate 1. The adjustment rod 5 passes through the support frame 4, and the positioning ring 3 is sleeved on the adjustment rod 5. The inner hole of the positioning ring 3 is clearance-fitted with the adjustment rod 5, allowing the positioning ring 3 to slide synchronously with the sliding member along the length of the adjustment rod 5. A locking assembly is provided on the adjustment rod 5 to lock the positioning ring 3 onto the adjustment rod 5, thereby simultaneously fixing the position of the sliding member and allowing the clamping plate 6 to clamp the building component.

[0039] Working principle:

[0040] S1. Place the positioning plate:

[0041] Move the positioning plate 1 to the edge structure of the building to be worked on, such as the top of the parapet wall or the top of the exterior wall panel, so that the bottom surface (i.e., the contact surface) of the positioning plate 1 is in contact with the top surface of the building edge structure, ensuring that the positioning plate 1 is placed horizontally and is stable as a whole, providing basic support for subsequent structural installation. At this time, the end of the positioning plate 1 that needs to be suspended from the work platform faces the working side, and the installation components of the positioning plate 1 are in the ready-to-connect state.

[0042] S2. Adjust the positioning adjustment mechanism:

[0043] Based on the thickness of the building edge structure, the positioning adjustment mechanism is pre-adjusted, and the sliding part is pushed to slide along the length direction of the positioning plate 1, that is, along the thickness direction parallel to the building edge structure, which drives the clamping plate 6 at the bottom of the sliding part to move synchronously, so that the clamping surface of the clamping plate 6 gradually approaches the side of the building edge structure.

[0044] Continue sliding until the clamping surface of the clamping plate 6 is initially in contact with the side of the building edge structure. At this time, the positioning ring 3 at the top of the sliding part slides synchronously along the adjusting rod 5 with the sliding part, and the positioning ring 3 is in the appropriate position of the adjusting rod 5.

[0045] S3. Locking and fixing of the positioning adjustment mechanism:

[0046] The position of the sliding member is locked by adjusting the locking component of the assembly, so as to achieve a firm clamping of the clamping plate 6 to the building edge structure: operate the locking component on the adjusting rod 5, and rotate the two sets of locking components to both sides of the positioning ring 3 respectively; gradually tighten the locking components on both sides of the positioning ring 3 so that the locking components are tightly abutted against the side wall of the positioning ring 3, and restrict the positioning ring 3 from sliding along the adjusting rod 5 by the locking components, thereby fixing the position of the sliding member;

[0047] Once it is confirmed that the clamping surface of the clamping plate 6 is tightly fitted to the side of the building edge structure without any looseness, the positioning plate 1 is firmly fixed to the building edge structure.

[0048] S4. Installation and adjustment of suspension components:

[0049] Install the suspension rod 2 and the work platform. Select a suspension rod 2 of appropriate length according to the working height requirements, set one end of it on the mounting part of the positioning plate 1, and adjust the extension length of the suspension rod 2; fix the suspension rod 2.

[0050] The work platform is installed on the end of the suspension rod 2 away from the positioning plate 1 (the working side) by a detachable connection method, such as bolt connection or snap-fit, to ensure a firm connection.

[0051] Once the operator enters the work platform and is secured with a safety rope, they can begin high-altitude work, such as exterior wall painting and component installation.

[0052] S5. Adjustment and relocation of work location:

[0053] If it is necessary to change the work position, the operator must first evacuate the work platform, disconnect the connection between the work platform and the suspension rod 2, and move the work platform to a safe area;

[0054] Loosen the locking assembly on the adjusting rod 5 to disengage the locking parts on both sides of the positioning ring 3 from the positioning ring 3, thus releasing the lock on the sliding part; push the sliding part to slide in the opposite direction along the positioning plate 1, causing the clamping plate 6 to disengage from the side of the building edge structure, thus releasing the clamping state; move the positioning plate 1 to a new working position, repeat steps S1-S4, and after re-completing the positioning, clamping, installation of the suspension components and safety confirmation, the work can continue.

[0055] The above-described working method enables the structure to be quickly adapted to, firmly fixed to, and flexibly transferred to building edge structures of different thicknesses. At the same time, multiple safety confirmation steps ensure the stability and safety of high-altitude operations.

[0056] In one embodiment, the mounting component includes a mounting cylinder 7, which is fixedly disposed at the end of the positioning plate 1. Preferably, the axial direction of the mounting cylinder 7 is perpendicular to the length direction of the positioning plate 1, and the mounting cylinder 7 extends vertically to meet the requirements of high-altitude suspension. The suspension rod 2 is a first screw with external threads on its outer circumferential surface, and its outer diameter is adapted to the inner diameter of the mounting cylinder 7. The suspension rod 2 coaxially passes through the mounting cylinder 7, and the suspension rod 2 and the mounting cylinder 7 are fitted with a clearance fit, allowing the suspension rod 2 to be freely inserted or withdrawn along the axial direction of the mounting cylinder 7, thus achieving movable installation. To achieve the positioning and height adjustment of the suspension rod 2 within the mounting cylinder 7, first nuts 8 are threadedly connected to the suspension rod 2 on both sides of the mounting cylinder 7.

[0057] When it is necessary to fix the position of the suspension rod 2, first insert the suspension rod 2 into the mounting cylinder 7 to the target height, and then tighten the first nuts 8 on both sides of the mounting cylinder 7 in sequence until the first nuts 8 are tightly abutting against the outer wall of the mounting cylinder 7. The axial clamping force of the first nuts 8 on both sides of the mounting cylinder 7 will fix the suspension rod 2 to the mounting cylinder 7, preventing the suspension rod 2 from sliding or rotating axially due to vibration, load and other factors during operation, and ensuring that it is firmly positioned in the mounting cylinder 7.

[0058] To adjust the height of the work platform, simply loosen the first nuts 8 on both sides of the mounting cylinder 7 in the opposite direction, disengaging the nuts from the outer wall of the mounting cylinder 7. Then, move the suspension rod 2 up and down along the axis of the mounting cylinder 7 to the new height. Tighten the first nuts 8 on both sides again to complete the fixation. This design achieves adjustable height and secure positioning of the suspension rod 2 through threaded engagement. It is easy to operate without complex tools, quickly adapting to the height requirements of different high-altitude work scenarios. Furthermore, the symmetrical arrangement of multiple sets of nuts disperses the clamping force, preventing excessive localized stress on the mounting cylinder 7 and thus extending the device's service life.

[0059] In this embodiment, two sets of equidistantly distributed first nuts 8 are threaded onto both sides of the suspension rod 2. Adjacent sets of first nuts 8 are distributed on one side of the mounting cylinder 7, allowing for the positioning of the suspension rod 2. Preferably, four sets of first nuts 8 are threaded onto the suspension rod 2, and these four sets are symmetrically distributed in two groups on both sides of the mounting cylinder 7: two groups are located on the side of the mounting cylinder 7 higher than the positioning plate 1, and the other two groups are located on the side of the mounting cylinder 7 lower than the positioning plate 1. The positioning plate 1 is fixedly connected to the side wall of the mounting cylinder 7. When the suspension rod 2 is installed inside the mounting cylinder 7, the threaded first nuts 8 on both sides of the suspension rod 2 can firmly position the suspension rod 2 within the mounting cylinder 7.

[0060] In one embodiment, the sliding element is a sliding box 9, which can be made of high-strength steel. The sliding box 9 has an overall U-shaped frame structure. The sliding box 9 is surrounded by a horizontally arranged top plate, a bottom plate, and two side plates that vertically connect the top plate and the bottom plate. A through cavity is formed in the middle of the sliding box 9 that is adapted to the cross-sectional shape of the positioning plate 1. Preferably, the positioning plate 1 has a rectangular cross-section, and the through cavity of the sliding box 9 is rectangular to ensure full fit with the outer wall of the positioning plate 1.

[0061] In this embodiment, the through cavity size of the sliding box 9 and the cross-sectional size of the positioning plate 1 are designed with a clearance fit. This ensures that the sliding box 9 can be smoothly installed along the outer wall of the positioning plate 1, while reducing wobbling during sliding. This ensures that the sliding box 9 moves linearly along the length direction of the positioning plate 1 (parallel to the thickness direction of the building edge structure), avoiding sliding deviation caused by excessive clearance. At the same time, the side wall of the through cavity in the sliding box 9 has a wear-resistant layer, which can reduce frictional wear with the outer wall of the positioning plate 1 and extend the service life of the sliding fit structure.

[0062] The clamping plate 6 is vertically fixed to the bottom surface of the base plate of the sliding box 9. The clamping plate 6 and the sliding box 9 are fixedly connected by welding to ensure that the connection strength is sufficient to withstand the clamping force during high-altitude operations. Preferably, the clamping surface of the clamping plate 6 is perpendicular to the sliding direction of the sliding box 9, ensuring that the clamping plate 6 is always facing the side of the building edge structure during the sliding process, thus improving the clamping stability. The positioning ring 3 is vertically fixed to the top surface of the top plate of the sliding box 9. The two are fixed by integral molding or welding. The axis of the positioning ring 3 is coaxial with the axis of the adjusting rod 5. When the positioning ring 3 slides synchronously with the sliding box 9, its central axis always coincides with the axis of the adjusting rod 5. The sliding box 9 adopts a U-shaped structure design. Its top plate, bottom plate and side plates form a closed frame. When it is fitted on the outside of the positioning plate 1, it can form a wrapping constraint on the positioning plate 1 from four directions: top, bottom and left, effectively preventing the sliding box 9 from tilting or flipping during the sliding or clamping process, further enhancing the overall stability of the positioning adjustment mechanism.

[0063] In practical applications, there are two sets of sliding boxes 9, symmetrically distributed on both sides of the positioning plate 1 and spaced apart along the length of the positioning plate 1. Each set of sliding boxes 9 is connected to a set of clamping plates 6, which can simultaneously clamp from both sides of the building edge structure. With the locking force of the adjustment component, a "double-sided clamping" effect is formed on the building edge structure, which greatly improves the fixing reliability of the positioning plate 1.

[0064] In one embodiment, a slider-rail mating structure can also be used, where the slider is the sliding element, and the positioning plate 1 has a rail adapted to the slider along its length, such as a T-rail. The bottom of the slider has a groove that matches the rail, and the slider slides with the rail through the groove. The sliding rail and slider have high mating precision and low sliding resistance. Lateral displacement of the slider can be prevented by the limiting edge on the side of the rail. The top of the slider is fixed with a positioning ring 3, and the bottom is fixed with a clamping plate 6.

[0065] In one embodiment, anti-slip rubber blocks 10 are installed on the inner sides (i.e., the side facing the building edge structure) of both sets of clamping plates 6. The anti-slip rubber blocks 10 are detachably connected to the clamping plates 6 by bolts, and anti-slip textures are formed on the inner sides of both sets of anti-slip rubber blocks 10. When the two sets of clamping plates 6 are distributed on both sides of the parapet wall, the anti-slip rubber blocks 10 installed on the inner sides of the clamping plates 6 further increase the stability and anti-slip ability of the clamping plates 6.

[0066] In one embodiment, the support frame 4 is specifically configured as two, and the two support frames 4 are distributed symmetrically and opposite to each other along the length direction of the positioning plate 1. The support frame 4 is made of high-strength steel plate and has an overall upright column structure. The bottom surface of the support frame 4 is fixed to the top surface of the positioning plate 1 by welding or bolting.

[0067] The adjusting rod 5 is fixedly connected to two support frames 4 at both ends, which can be done by welding or threaded connection. The two positioning rings 3 corresponding to the two sets of sliding parts are sleeved on the adjusting rod 5, and the central axis of the positioning ring 3 coincides with the central axis of the adjusting rod 5. This design can ensure that the inner wall of the positioning ring 3 is in uniform contact with the outer circumferential surface of the adjusting rod 5 when the sliding parts slide.

[0068] Meanwhile, the adjusting rod 5 is parallel to the top surface of the positioning plate 1, ensuring that the cooperation between the positioning ring 3 and the adjusting rod 5 remains consistent when the sliding member slides along the length of the positioning plate 1, thus ensuring a uniform distribution of the clamping force of the locking assembly on the positioning ring 3. The uniform distance between the adjusting rod 5 and the top surface of the positioning plate 1 prevents interference between the sliding member and the top surface of the positioning plate 1 or the adjusting rod 5 during sliding, ensuring smooth sliding adjustment. When clamping the edge structure of a building, the locking force can be evenly transmitted to the positioning plate 1, avoiding deformation of the positioning plate 1 caused by local stress concentration, and significantly improving the overall structural stability of the device.

[0069] In one embodiment, the adjusting rod 5 is a metal rod with external threads machined on its outer circumference, serving as a second screw. The locking component includes a second nut 11, which is threaded onto the adjusting rod 5. Preferably, four sets of equally spaced second nuts 11 are threaded onto the adjusting rod 5. The four sets of nuts are distributed along the axial direction of the adjusting rod 5 and form a corresponding engagement relationship with the two sets of positioning rings 3 as follows: each side of each positioning ring 3 is provided with a set of second nuts 11, that is, the first positioning ring has a first and second set of nuts on both sides, and the second positioning ring has a third and fourth set of nuts on both sides.

[0070] The adjusting rod 5 is movably connected to the two sets of positioning rings 3. The inner diameter of the positioning ring 3 is adjusted by the gap between the outer diameter of the adjusting rod 5 and the inner diameter of the adjusting ring 3. This ensures that the positioning ring 3 can slide smoothly along the adjusting rod 5 with the sliding box 9, while also ensuring the coaxiality of the positioning ring 3 and the adjusting rod 5 through a small gap.

[0071] When it is necessary to fix the position of the sliding box 9, first slide the sliding box 9 to the target position so that the clamping plate 6 fits against the edge structure of the building. At this time, the positioning ring 3 moves synchronously with the sliding box 9 to the corresponding position on the adjusting rod 5. Then, tighten the second nuts 11 on both sides of the positioning ring 3 in sequence so that the nut on the side closer to the positioning ring 3 gradually comes into close contact with the end face of the positioning ring 3, and the nut on the other side is tightened in the opposite direction until it fits against the other end face of the positioning ring 3. The two sets of nuts form a "two-way clamping" force on the positioning ring 3, which firmly locks the positioning ring 3 on the adjusting rod 5, thereby fixing the position of the sliding box 9 and the clamping plate 6.

[0072] The independent adjustment of the four sets of nuts allows for individual clamping force to be applied to each set of positioning rings 3, adapting to the thickness differences of different building edge structures. This ensures that the two sets of clamping plates 6 are evenly clamped from both sides, preventing the positioning plate 1 from tilting due to excessive force on one side. The bidirectional clamping of the nuts on both sides can offset external forces such as vibration and impact during operation, preventing the positioning rings 3 from sliding along the axial direction of the adjusting rod 5. Through the rigid connection between the positioning rings 3 and the sliding box 9, the locking force of the nuts can be directly transmitted to the clamping plates 6, ensuring that the clamping plates 6 are always tightly engaged with the building edge structure (such as the parapet wall), effectively preventing the overall displacement or detachment of the device, providing reliable safety for the operators on the work platform, and greatly improving the safety of the operators on the work platform.

[0073] In one embodiment, the adjustment assembly further includes an auxiliary support structure, including an adjustment cover 12 fixedly installed on the outer wall of the clamping plate 6 (the side away from the building edge structure). A support rod 13 is rotatably mounted on the end of the positioning plate 1 away from the mounting cylinder 7 via a pivot. The hinge point between the support rod 13 and the positioning plate 1 is connected by a pin. Multiple sets of positioning holes 14 are spaced apart along the length of the side wall of the adjustment cover 12. The spacing between adjacent positioning holes 14 corresponds to the adjustment step distance of the support rod 13, adapting to building edge structures of different thicknesses. One end of the support rod 13 is hinged to the positioning plate 1 via a pin, and the side wall of the other end (free end) has a through hole adapted to the positioning hole 14 of the adjustment cover 12. When the support rod 13 is aligned with the positioning hole 14 of the adjustment cover 12, inserting a positioning pin achieves a fixed connection between the support rod 13 and the adjustment cover 12.

[0074] After the two sets of clamping plates 6 are clamped from both sides of the building edge structure, the operator can rotate the support rod 13 so that its free end is close to the adjusting cover 12 of the outer clamping plate 6. The operator then selects the aligned positioning hole 14 according to the actual thickness of the building edge structure and inserts the positioning pin to complete the fixation. At this point, the support rod 13, the outer clamping plate 6, and the positioning plate 1 form a stable triangular support structure. This transfers the clamping reaction force borne by the outer clamping plate 6 to the positioning plate 1 through the support rod 13, effectively dispersing the localized stress on the clamping plate 6 and preventing deformation or loosening of the clamping plate 6 due to long-term load-bearing or external impact. Furthermore, the distribution of multiple positioning holes 14 can adapt to building edge structures of different thicknesses. Simply adjusting the connection position between the support rod 13 and the adjusting cover 12 ensures that the triangular support is always in the optimal stress state. The rotation of the support rod 13 and the insertion / removal of the positioning pin can be completed quickly without complex tools, meeting the high-efficiency requirements of high-altitude operations.

[0075] In one embodiment, the work platform is specifically a suspended platform 15, which is welded from high-strength steel. The main body of the suspended platform 15 includes a horizontally arranged rectangular base plate, a front baffle vertically fixed to the front end of the base plate, a rear fixed plate vertically fixed to the rear end of the base plate, and side railings connecting the front baffle and the rear fixed plate on both sides, forming a closed frame structure with "protection on all four sides and an opening at the top". Multiple reinforcing ribs are welded at intervals along the length of the base plate of the suspended platform 15 to ensure that the suspended platform 15 has good overall load-bearing capacity. The connection between the suspended platform 15 and the suspension rod 2 adopts a detachable bolt connection structure.

[0076] A connector 16 is provided at the end of the suspension rod 2 (the end furthest from the positioning plate 1), and the axis of the connector 16 coincides with the axis of the suspension rod 2. The outer surface of the connector 16 is machined with an installation plane, on which multiple sets of threaded holes are spaced vertically. A through hole is provided at the corresponding position on the rear fixing plate of the suspended platform 15, and high-strength bolts are used to securely connect it to the installation plane of the connector 16. Preferably, the height of the front baffle of the suspended platform 15 is lower than that of the rear fixing plate, which avoids obstructing the operator's field of vision and provides lumbar support when the operator leans forward. The height of the side guardrail is the same as that of the rear fixing plate, and the connection between the front baffle and the side guardrail uses a rounded corner transition to prevent bumps and damage.

[0077] In use, the device is first transported to the top of the building and then installed. The suspension rods 2 of the corresponding length are matched, and the suspended platform 15 is installed on the suspension rods 2 (first screw). After the positioning plate 1 is fixed at one end of the building, the operator can stand inside the suspended platform 15 to perform high-altitude work. Simultaneously, when the positioning plate 1 is placed on the top of the parapet wall, the two sets of sliding boxes 9 on the positioning adjustment mechanism can be slid, so that the clamping plates 6 at the bottom of the two sets of sliding boxes 9 respectively fit against both sides of the parapet wall. Then, the multiple sets of second nuts 11 on the adjusting rod 5 (second screw) are tightened sequentially. Distributed on both sides of the positioning ring 3, it can position the sliding box 9 at the bottom of the positioning ring 3, ensuring that the two sets of clamps 6 on the positioning plate 1 are firmly locked onto the parapet wall, greatly improving the safety of the operators on the suspended platform 15. At the same time, positioning holes 14 are opened on the adjusting cover 12. After the operator installs the two sets of clamps 6, he can adjust the support rod 13 on the positioning plate 1 and fit it into the inside of the adjusting cover 12. By inserting the pins into the corresponding positioning holes 14, the clamps 6 on the outside can be effectively supported, further increasing the stability and safety of the device.

[0078] In one embodiment, to further enhance the connection rigidity between the positioning plate 1 and the mounting cylinder 7, a reinforcing rod 17 is fixedly connected to the positioning plate 1. The reinforcing rod 17 is made of high-strength steel. One end of the reinforcing rod 17 is fixedly connected to the side wall of the positioning plate 1, with the connection position located at the middle of the length direction of the positioning plate 1 and close to the side of the mounting cylinder 7. The other end of the reinforcing rod 17 is fixedly connected to the outer wall of the mounting cylinder 7, with the connection point preferably located at the lower middle part of the height direction of the mounting cylinder 7. This forms a stable right-angled triangular support structure with the reinforcing rod 17, the mounting cylinder 7, and the positioning plate 1. The two right-angled sides are part of the length of the positioning plate 1 and part of the height of the mounting cylinder 7, respectively, and the hypotenuse is the reinforcing rod 17.

[0079] The reinforcing rod 17 is fixedly connected to the positioning plate 1 and the mounting cylinder 7 by welding or bolts. Utilizing the geometric stability of a triangle, the vertical suspension force borne by the mounting cylinder 7 is converted into the axial tensile force of the reinforcing rod 17 and the supporting force of the positioning plate 1, thereby improving overall stability and rigidity, further enhancing load-bearing redundancy, and adapting to heavy-duty operation scenarios.

[0080] In one embodiment, mounting cylinders 7 are fixedly installed at both ends of one side of the positioning plate 1 (the working side away from the building edge structure). Suspension rods 2 (first screws) are movably installed within both sets of mounting cylinders 7. The ends of both sets of suspension rods 2 can be detachably mounted with a suspended platform 15. Several sets of suspension rods 2 can be provided, with varying lengths to adjust the height of the suspended platform 15. Each set of suspension rods 2 is locked to the corresponding mounting cylinder 7 by a first nut 8. The operator can replace suspension rods 2 of different lengths and install them on the mounting cylinders 7 to adjust the height of the suspended platform 15, facilitating high-altitude operations.

[0081] Working methods for temporary suspended structures in high-altitude construction projects:

[0082] S1. Placement of the positioning plate and foundation positioning:

[0083] Based on construction requirements, determine the building edge structure to be worked on, such as the top of the parapet wall, and clear debris from the surface of this location to ensure a flat supporting surface. Move the positioning plate 1 to the building edge structure, ensuring its bottom surface (contact surface) is tightly fitted against the top surface of the building edge structure. Adjust the positioning plate 1 to a level position using a level to ensure overall stability. The side of the positioning plate 1 with the mounting cylinder 7 (working side) faces the exterior wall to be worked on, reserving working space for the subsequent suspension of the suspended platform 15.

[0084] S2. Adjustment and locking of the positioning adjustment mechanism:

[0085] Based on the thickness of the building edge structure, push the two sets of sliding boxes 9 to slide along the length direction of the positioning plate 1 (parallel to the thickness direction of the building edge structure), slowly slide the sliding boxes 9, and drive the clamping plate 6 to move closer to both sides of the building edge structure until the anti-slip rubber block 10 on the inner side of the clamping plate 6 is in contact with the side of the building edge structure.

[0086] After confirming that the two sets of clamping plates 6 are distributed on both sides of the building edge structure, operate the four sets of second nuts 11 on the adjusting rod 5. Tighten the second nuts 11 on both sides of each positioning ring 3 to the positioning ring 3, so that the end face of the nut is in close contact with the end face of the positioning ring 3, forming a "two-way clamping" force. During the tightening process, keep the force on both sides of the nuts even, which can cause the clamping plates 6 to drive the anti-slip rubber blocks 10 to be slightly compressed. At this time, the anti-slip texture of the anti-slip rubber blocks 10 engages with the building surface, completing the clamping and fixing.

[0087] S3. Installation of auxiliary support structure:

[0088] For the outer clamping plate 6 (the side furthest from the building interior), rotate the support rod 13 at the end of the positioning plate 1 so that its free end fits against the adjusting cover 12 on the outside of the clamping plate 6. Adjust the position of the support rod 13 according to the thickness of the building edge structure so that the through hole at the free end of the support rod 13 is aligned with the positioning hole 14 on the adjusting cover 12. Insert the positioning pin to ensure that the support rod 13, the outer clamping plate 6, and the positioning plate 1 form a stable right-angled triangular support structure.

[0089] S4. Installation and height adjustment of suspension components:

[0090] Suspension rod selection and installation: Based on the required working height, select a suspension rod 2 (first screw) of the appropriate length. Screw one end (with external thread) into the mounting sleeve 7 at the end of the positioning plate 1. Tighten four sets of first nuts 8 (distributed symmetrically in two groups) on the upper and lower sides of the mounting sleeve 7 until they are tightly against the outer wall of the mounting sleeve 7. Fix the suspension rod 2 with axial clamping force to prevent axial sliding or rotation. Hoist the suspended basket 15 below the suspension rod 2, aligning the through hole of the rear fixing plate of the suspended basket 15 with the threaded hole of the mounting plane of the end connector 16 of the suspension rod 2, and fasten the connection with high-strength bolts.

[0091] S5. High-altitude operations implementation:

[0092] The operator enters the suspended platform 15 by passing through the edge structure of the building, and is secured with a safety rope. The operator must keep their body within the protective range of the suspended platform 15 while performing the operation.

[0093] S6. Adjustment or relocation of work location:

[0094] If the work position needs to be adjusted, the operator should first stop work, evacuate to a safe area at the edge of the building structure, and disconnect the safety rope from the suspended platform 15. Loosen the connecting bolts between the suspended platform 15 and the suspension rod 2, and hoist the suspended platform 15 to the building platform for temporary storage. Loosen the second nut 11 on the adjusting rod 5 in the opposite direction to disengage the nuts on both sides of the positioning ring 3 from the positioning ring 3, thus releasing the lock on the sliding box 9; at the same time, pull out the positioning pins of the support rod 13 and the adjusting cover 12, and rotate the support rod 13 to the non-supported position.

[0095] Push the sliding component to move the clamping plate 6 away from the building edge structure, move the positioning plate 1 to the new working position, repeat steps S1-S5, and after re-performing the positioning, clamping, suspension installation and safety confirmation, continue the work.

[0096] S7: Work Completion and Equipment Dismantling:

[0097] After the operators evacuate the suspended platform 15, disconnect the connection between the suspended platform 15 and the suspension rod 2, and move the suspended platform 15 to the ground. Loosen the first nuts 8 on both sides of the mounting cylinder 7, unscrew the suspension rod 2 from the mounting cylinder 7, and store it separately. Completely loosen the second nut 11 and remove the sliding box 9.

[0098] This structure can be quickly adapted to and firmly fixed to different building edge structures. It ensures operational safety through multiple locking (nut clamping), anti-slip (anti-slip rubber blocks), and support (triangular structure) designs. At the same time, it can adapt to the needs of high-altitude operations in various scenarios through modular disassembly and adjustment. It is easy to operate and highly stable.
