Description

Technical Field

[0001] This invention relates to the field of high-altitude construction technology in building construction, and particularly to a safety suspension device for high-altitude construction in building construction. Background Technology

[0002] In high-altitude exterior wall construction, maintenance, and decoration of building projects, the lever-type counterweight suspended platform is the most widely used supporting structure for high-altitude operations. Based on the principle of lever mechanics, it consists of a front support, a rear support, a cantilever beam, and counterweight blocks. Its core advantages are: easy installation and disassembly without requiring large-scale modifications to the building structure; and reusable components, resulting in good economic efficiency. Therefore, it is widely used in the industry.

[0003] Despite its mature application, this mechanism suffers from a core drawback that is difficult to avoid: the counterweights must be concentrated on the counterweight frame at the top of the rear support, resulting in a typical localized concentrated load that acts directly on the roof panel surface. Conventional roof panels, especially lightweight roofs, insulated roofs, and cast-in-place thin slabs, have relatively low design load-bearing capacity, and the localized pressure generated by the counterweights significantly exceeds the roof panel's design allowable load-bearing capacity. To ensure the stabilizing torque meets standards, hundreds or even thousands of kilograms of counterweights often need to be stacked on-site. Furthermore, to improve anti-overturning performance, the counterweights are usually placed as far back as possible, further increasing the concentrated stress at the bottom of the rear support and placing an even greater load on the roof panel. Prolonged stress can easily lead to cracking, deflection, and even localized structural damage to the roof panel, posing a potential safety hazard to the building structure.

[0004] To address the aforementioned problem of concentrated counterweight loads, some improved solutions have emerged in existing technologies. For example, the counterweight-free suspended platform device (CN113120774B) replaces the counterweight by drilling holes in the structural wall for anchoring. This directly compromises the wall's integrity, leading to cracking and leakage, and also exhibits poor adaptability, easily damaging walls with lower strength. Another example is the counterweight-free high-altitude work platform device (CN220768805U), which replaces the counterweight by anchoring components through the parapet wall and anchoring to the roof structural beam. This solution causes double damage to the building structure: firstly, drilling holes in the parapet wall weakens its structural strength, easily leading to cracking, leakage, or even collapse; secondly, drilling holes in the structural beam to implant anchors damages the beam's reinforcing steel protective layer, affecting the beam's load-bearing capacity, and the holes are difficult to repair later.

[0005] In summary, existing lever-type counterweight suspended platforms and related improvement solutions all have defects: conventional mechanisms have concentrated counterweights and large weights, which can easily damage the roof panels; while improvement solutions will damage the building's wall structure or structural beams. Neither can effectively solve the roof bearing pressure problem caused by concentrated counterweight loads without damaging the main structure of the building. Summary of the Invention

[0006] This invention provides a safety suspension device for high-altitude construction of buildings, which can solve the problem in the prior art that it is impossible to effectively avoid the concentrated load of the counterweight exceeding the roof panel's bearing capacity and easily damaging the roof panel without damaging the main structure of the building.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a safety suspension device for high-altitude construction of buildings, including a rear support assembly, a front support assembly, and a crossbeam assembly installed on both. The cantilever end of the crossbeam assembly is provided with a suspension assembly, and the bottom end of the rear support assembly is rotatably connected to a counterweight bearing member. The counterweight bearing member is a long strip-shaped bearing plate, which is used to fit along the length of the structural beam to directly transfer the load of the counterweight to the structural beam and disperse local pressure. The cantilever frame is height-adjustably mounted on the front support assembly. A structural beam fastener is rotatably mounted on the cantilever frame. The structural beam fastener includes a vertical rod assembly and a horizontal plate assembly. The vertical rod assembly extends from the cantilever frame to the window opening and provides support for the horizontal plate assembly. The horizontal plate assembly is located at the bottom of the vertical rod assembly and extends into the room from the window opening, pressing upwards against the bottom of the structural beam to form an anti-overturning constraint. This allows the structural beam to assist the front support assembly in providing anti-overturning and vertical support for the horizontal beam assembly.

[0008] Preferably, the vertical rod assembly includes a threaded sleeve rod that is threadedly and vertically connected to the cantilever frame and a rotating inner rod that is rotatably connected to the threaded sleeve rod on the same axis, and the horizontal plate assembly is fixedly connected to the bottom end of the rotating inner rod.

[0009] Preferably, an axial limiting structure is provided between the threaded sleeve and the rotating inner rod to prevent the rotating inner rod from moving axially.

[0010] Preferably, the axial limiting structure consists of two constraint plates fixedly connected to the rotating inner rod, with the two constraint plates respectively located at the top and bottom of the threaded sleeve rod.

[0011] Preferably, the horizontal plate assembly includes a clamping horizontal plate and a U-shaped surrounding column frame; The surrounding frame is fixedly connected to the bottom end of the rotating inner rod, and is used to bypass the structural column and provide support for the clamping horizontal plate; The clamping cross plate is fixedly connected to the end of the column frame and is used to press tightly against the bottom of the structural beam.

[0012] Preferably, the horizontal plate assembly further includes a clamping vertical plate fixedly connected to the side of the column frame, wherein the clamping vertical plate is arranged to clamp the horizontal plate vertically to form an L-shaped clamping structure.

[0013] Preferably, a tie rod is provided between the cantilever frame and the rear support assembly.

[0014] Preferably, the counterweight bearing component includes two long strip-shaped bearing plates arranged perpendicularly to each other, and the width of the long strip-shaped bearing plates is not greater than 200mm.

[0015] Preferably, the front support assembly includes a transverse support rod, a longitudinal support rod, and a vertical support rod; The vertical support rod is positioned above the horizontal support rod and is used to support the beam assembly; the longitudinal support rod is positioned horizontally and perpendicular to the horizontal support rod; and diagonal reinforcing rods are provided between the horizontal support rod, the longitudinal support rod, and the vertical support rod.

[0016] Compared to existing technologies, this invention, by setting a rotatable, elongated counterweight bearing member at the bottom of the rear support assembly, allows for flexible adjustment of its direction and allows it to be arranged close to the structural beam along its length. This directly and completely transfers the concentrated load of the counterweight to the load-bearing components of the roof structure, effectively dispersing local pressure and preventing the concentrated load from crushing the roof panel, causing cracks and leaks, through the force transmission path. Simultaneously, an adjustable-height, rotatable structural beam fastener is installed on the front support assembly. Utilizing the cooperation of the vertical rod assembly and the horizontal plate assembly, the horizontal plate assembly can extend into the interior from the window opening and press firmly against the bottom of the structural beam, forming a reliable anti-tipping structure. The overturning constraint means that when the suspended platform is under stress and has a tendency to overturn, the structural beams actively provide upward support reaction force and anti-overturning moment, which greatly reduces the device's reliance on the weight of the rear counterweight block, thereby reducing the number of counterweights used and further reducing the overall stress load on the roof. This device does not require drilling, anchoring, or implanting components in the walls, parapet walls, or structural beams throughout the entire process. Without compromising the integrity of the main building structure, it solves the technical problems of concentrated counterweight damage to the roof caused by traditional counterweight suspended platforms and damage to the building structure caused by existing improvement schemes. The structure has a reasonable stress distribution, is easy to install and adjust, and its safety, stability, and structural protection are significantly improved. Attached Figure Description

[0019] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1 to 4 As shown, this invention provides a safety suspension device for high-altitude construction in building construction, including a rear support assembly 1, a front support assembly 2, and a crossbeam assembly 3 mounted on both. A suspension assembly 4 is provided at the cantilever end of the crossbeam assembly 3. A counterweight bearing member 5 is rotatably connected to the bottom end of the rear support assembly 1. The counterweight bearing member 5 is a long strip-shaped bearing plate used to fit along the length of the structural beam 11, so as to directly transfer the load of the counterweight to the structural beam 11 and distribute local pressure. The front support assembly 2... A cantilever frame 6 is installed at an adjustable height. A structural beam fastener is rotatably mounted on the cantilever frame 6. The structural beam fastener includes a vertical rod assembly and a horizontal plate assembly 9. The vertical rod assembly extends from the cantilever frame 6 to the window opening and is used to support the horizontal plate assembly 9. The horizontal plate assembly 9 is located at the bottom of the vertical rod assembly and is used to extend into the room from the window opening and push upward to the bottom of the structural beam 11 to form an anti-overturning constraint. This allows the structural beam 11 to assist the front support assembly 2 in providing anti-overturning and vertical support for the horizontal beam assembly 3.

[0021] Specifically, the rear support assembly 1 is mainly used to support the tail of the crossbeam assembly 3 and bear the counterweight. It is the rear load-bearing foundation of the entire device. It is made of Q235B steel or square steel pipe and has sufficient compressive and bending strength. When setting it up, the overall verticality and stability of the rear support assembly 1 should be ensured to avoid tilting or slipping after being subjected to force.

[0022] The counterweight bearing component 5 is a long strip-shaped bearing plate at the bottom of the rear support assembly 1, used to directly adhere to the structural beam 11 and transfer the counterweight load. It is made of steel plate with a thickness of not less than 8mm, possessing sufficient rigidity and compressive strength. It should be noted that the counterweight bearing component 5 is rotatably connected to the rear support assembly 1, allowing for free adjustment of the angle according to the orientation of the structural beam 11, ensuring close contact and force distribution along the beam's length. Specifically, it can be rotatably connected to the rear support assembly 1 via a pivot and locked with locking bolts 501. The counterweight should be centrally stacked on the two mutually perpendicular long strip-shaped bearing plates of the counterweight bearing component 5, ensuring that the line of action of the resultant load coincides with the centerline of the structural beam 11, avoiding eccentric loading that could cause slippage or warping of the counterweight bearing component 5. During stacking, it should be neatly arranged and compacted layer by layer, without being tilted, suspended, or extending beyond the edge of the counterweight bearing component 5, to prevent the counterweight from falling. It should be noted that the total weight of the counterweight should meet the mandatory requirements of the "General Specification for Construction Scaffolding" GB55023 regarding the overturning safety factor of the suspension mechanism, and should not exceed the allowable bearing capacity of the counterweight bearing component 5 and the structural beam 11. In addition, limiting or locking measures should be installed between the counterweight and the counterweight bearing component 5 to prevent slippage or displacement during operation, ensuring the stable and vertical transfer of the counterweight load to the structural beam 11.

[0023] The front support assembly 2 is used to support the front of the crossbeam assembly 3 and is the main support structure at the front of the device. It is made of high-strength square steel pipe or I-beam welded together, which has strong overall rigidity and is not easily deformed. When setting it up, the front support assembly 2 should be placed stably, and anti-slip pads can be added to the bottom to prevent slippage or shaking during the stress process.

[0024] The crossbeam assembly 3 is erected above the rear support assembly 1 and the front support assembly 2. It is the main load-bearing cantilever beam of the device. The material selected is I-beam, channel steel or high-strength rectangular beam. The cantilever length is determined according to the construction requirements. It should be noted that the crossbeam assembly 3 must ensure straightness and bending strength to avoid excessive stress on the cantilever end and downward deflection.

[0025] The suspension assembly 4 is installed at the cantilever end of the crossbeam assembly 3 and is used to suspend the suspended platform, wire rope and lifting mechanism. It is the direct suspension component of the aerial work platform. The material is cast steel or thick-walled stamped parts with sufficient tensile and shear strength. When installing, it should be ensured that the connection is firm and there is no looseness.

[0026] The cantilever frame 6 is installed on the front support assembly 2 and is used to connect to and support the structural beam fasteners across the parapet wall 13. It is made of shaped steel or rectangular steel pipes, possessing sufficient tensile and bending strength. It should be noted that the cantilever frame 6 is connected to the front support assembly 2 in a height-adjustable manner, allowing for flexible adjustment of the installation height according to the roof elevation and window opening location. The height of the cantilever frame 6 can be adjusted using bolts and pre-drilled holes.

[0027] The structural beam fastener is used to tighten the structural beam 11 from the interior side to provide anti-overturning restraint. It consists of a vertical rod assembly and a horizontal plate assembly 9, both made of high-strength structural steel to ensure they do not bend or deform under load. During installation, the fastener should be able to rotate freely to allow it to extend into the room through the window opening and align with the bottom of the structural beam 11. The vertical rod assembly connects the cantilever frame 6 and the horizontal plate assembly 9, providing vertical support and height adjustment. Its overall length is determined by the height from the roof to the window opening, and it possesses sufficient axial load-bearing capacity. It is important to ensure the vertical rod assembly remains vertical to prevent tilting that could cause the horizontal plate assembly 9 to shift under stress. The horizontal plate assembly 9 is located at the bottom of the vertical rod assembly, extending through the window opening into the room and abutting against the bottom of the structural beam 11. It is the core component forming the anti-overturning restraint. The specific implementation can adopt a flat, L-shaped, or T-shaped structure. During installation, its top surface should be flat and fully fitted with the bottom of the structural beam 11 to increase the load-bearing area.

[0028] In practical use, first place the rear support assembly 1 at the designated position on the roof, rotate the counterweight bearing 5 at its bottom end to make it fit along the length of the structural beam 11, and transfer the weight of the counterweight directly to the structural beam 11; then place the front support assembly 2 in place, first adjust the height of the cantilever frame 6 so that the horizontal plate assembly 9 is lower than the bottom of the window opening, then rotate the structural beam fastener to turn the horizontal plate assembly 9 into the room through the window opening, then adjust the cantilever frame 6 and the structural beam fastener upward so that the horizontal plate assembly 9 pushes upward and fastens against the bottom of the structural beam 11, forming an anti-overturning constraint. The structural beam 11 assists the front support assembly 2 in anti-overturning and vertical support the horizontal beam assembly 3. Finally, the working platform is suspended through the suspension assembly 4 at the cantilever end of the horizontal beam assembly 3, and the installation of the device is completed and put into use.

[0029] like Figures 1 to 5 As shown, in order to solve the problem that the height and angle of the structural beam fasteners cannot be adjusted independently and are difficult to adapt to different window openings and structural beam 11 positions, preferably, the vertical rod assembly includes a threaded sleeve rod 7 that is threadedly raised and lowered with the cantilever frame 6 and a rotating inner rod 8 that is coaxially rotatably connected within the threaded sleeve rod 7, and the horizontal plate assembly is fixedly connected to the bottom end of the rotating inner rod 8.

[0030] Specifically, the threaded sleeve rod 7 and the rotating inner rod 8 are used separately, and the horizontal plate assembly 9 can be rotated independently while raising and lowering the height, realizing the step-by-step operation of "first lowering, then rotating in, and finally tightening". The adjustment is flexible and the positioning is precise, which can be adapted to buildings with different floor heights and different window opening heights, greatly improving the versatility of the device.

[0031] The threaded sleeve 7 is used to achieve overall lifting and adjustment. It is connected to the cantilever frame 6 by threaded lifting. It is made of 45# steel or Q355 high-strength steel pipe, and the outer wall is machined with standard transmission threads. It should be noted that the lifting stroke of the threaded sleeve 7 should cover the commonly used roof and window opening height difference range to ensure sufficient adjustment margin.

[0032] The rotating inner rod 8 is used to drive the horizontal plate assembly 9 to rotate independently. It is coaxially installed inside the threaded sleeve rod 7 and is made of high-strength round steel with a smooth surface and smooth rotation without jamming. When setting it up, it should be ensured that the rotating inner rod 8 can rotate freely 360° without interfering with the threaded sleeve rod 7.

[0033] like Figure 5 As shown, in order to prevent the rotating inner rod 8 from moving up and down during lifting and rotation, and to prevent the horizontal plate assembly 9 from detaching from the structural beam 11, preferably, an axial limiting structure is provided between the threaded sleeve rod 7 and the rotating inner rod 8 to prevent the rotating inner rod 8 from moving axially.

[0034] Specifically, by using an axial limiting structure to constrain the axial displacement of the rotating inner rod 8, the horizontal plate assembly 9 is always kept within a reasonable height range, preventing failure of the clamping mechanism due to movement, thus improving the stability and safety of the anti-overturning constraint.

[0035] The axial limiting structure is used to restrict the vertical movement of the rotating inner rod 8. It is set between the threaded sleeve rod 7 and the rotating inner rod 8. The material is steel plate or annular baffle, which has high strength and is not easily deformed. It should be noted that the limiting structure must be firmly fixed to the rotating inner rod 8 and should not loosen with rotation.

[0036] like Figure 5 As shown, in order to further clarify the form of the limiting structure and avoid complex structure and difficult processing, preferably, the axial limiting structure consists of two constraint plates 14 fixedly connected to the rotating inner rod 8, and the two constraint plates 14 are respectively set at the top and bottom of the threaded sleeve rod 7.

[0037] Specifically, a double-constraint plate structure is adopted, which is simple to process, easy to install, reliable in limiting movement, and does not affect the normal rotation of the inner rotating rod 8. It also facilitates assembly and subsequent maintenance. The constraint plates are used for axial limiting and are circular baffles or square steel plates. They are fixed on the inner rotating rod 8 and located at the upper and lower ends of the threaded sleeve rod 7, respectively. The material is Q235 steel plate. When setting them, the distance between the two constraint plates should match the length of the threaded sleeve rod 7 to limit movement without hindering rotation.

[0038] like Figures 1 to 6 As shown, in order to solve the problem that the horizontal plate assembly 9 cannot be smoothly extended into the room and press against the structural beam 11 due to the obstruction of the structural column 12, preferably, the horizontal plate assembly 9 includes a clamping horizontal plate 902 and a U-shaped column-wrapping frame 901. The surrounding frame 901 is fixedly connected to the bottom end of the rotating inner rod 8, and is used to bypass the structural column 12 and provide support for the clamping horizontal plate 902; The clamping plate 902 is fixedly connected to the end of the surrounding column frame 901 and is used to press tightly against the bottom of the structural beam 11.

[0039] Specifically, the U-shaped column-mounted frame 901 can bypass the structural column 12, allowing the clamping horizontal plate 902 to smoothly reach the bottom of the beam without colliding or interfering with the column, ensuring reliable clamping even at column nodes, thus expanding the applicable scenarios.

[0040] The surrounding frame 901 is used to avoid the structural column 12. It is a U-shaped steel frame welded to the bottom of the rotating inner rod 8. The material is square steel or flat steel. It should be noted that the opening size of the surrounding frame 901 should be larger than the cross-section of the common structural column 12 to ensure smooth bypass.

[0041] The clamping horizontal plate 902 is used to tighten the bottom of the structural beam 11. It is a flat load-bearing component, fixed to the end of the surrounding column frame 901, and is made of steel plate with a thickness of not less than 10mm. When installing, the top surface should be flat and fully fitted to the bottom of the beam to increase the load-bearing area. It should be noted that the clamping horizontal plate 902 and the surrounding column frame 901 are fully welded together, with continuous, full welds, no incomplete welds, and no missing welds, ensuring that no cracking, deformation, or relative displacement occurs under overturning loads. Simultaneously, the clamping horizontal plate 902 and the surrounding column frame 901 are kept vertically fixed, allowing the tightening force to be stably transmitted vertically to the internal beam 11. Additionally, a triangular reinforcing plate can be added between the two to improve the bending and shear strength and structural stiffness of the connection, preventing bending, deformation, or weld tearing under long-term stress, further enhancing the reliability and safety of the top-clamping support.

[0042] like Figure 7 As shown, in order to further improve the overturning resistance of the device and enable multiple mutually perpendicular structural beams to participate in the force, preferably, the horizontal plate assembly 9 also includes a clamping longitudinal plate 903 fixedly connected to the side of the column frame 901. The clamping longitudinal plate 903 is arranged to clamp the horizontal plate 902 vertically to form an L-shaped clamping structure.

[0043] Specifically, by setting a clamping longitudinal plate 903 perpendicular to the clamping horizontal plate 902 on the surrounding column frame 901, the clamping horizontal plate 902 can be clamped to the inner beam of the structure, and the clamping longitudinal plate 903 can be clamped to the side beam of the structure at the same time, so as to realize the synchronous force of the two-way beams, distribute the anti-overturning load to more structural beams, greatly improve the overall anti-overturning capacity and support stability, and avoid the safety risks caused by excessive force at a single point.

[0044] The clamping plate 902 is used to fasten the bottom of the inner beam of the top structure. It is the main load-bearing component and is fixed to the end of the surrounding column frame 901. It is made of high-strength steel plate with a thickness of not less than 10mm. When setting it, the top surface should be flat and fully fit with the bottom of the inner beam 11 of the structure to ensure uniform stress.

[0045] The clamping longitudinal plate 903 is used to clamp the bottom of the structural edge beam. It is arranged perpendicularly to the clamping transverse plate 902 and fixed to the side of the column frame 901. Its material and rigidity are consistent with those of the clamping transverse plate 902. It should be noted that the clamping longitudinal plate 903 and the clamping transverse plate 902 must be kept strictly perpendicular to each other in order to adapt to the mutually orthogonal structural inner beams and structural edge beams, and to ensure that the two plates can simultaneously clamp the corresponding beams.

[0046] like Figure 8 As shown, in order to achieve a rigid connection between the rear support assembly 1 and the cantilever frame 6, and to make the anti-overturning effect of the cross plate assembly 9 and the supporting effect of the rear support 1 form an overall force system, preferably, a tie rod 10 is provided between the cantilever frame 6 and the rear support assembly 1.

[0047] Specifically, by setting a tie rod 10 between the cantilever frame 6 and the rear support assembly 1, the anti-overturning force provided by the front structural beam fastener and the rear counterweight support force can be effectively transferred and coordinated, so that the entire device changes from distributed force to overall force, significantly improving structural rigidity and working stability, avoiding deformation of the cantilever frame 6 under individual force, and ensuring long-term safe use of the device.

[0048] Tie rod 10 is used to connect cantilever frame 6 and rear support assembly 1 to achieve force transmission and overall rigid constraint. High-strength round steel or thin-walled steel pipe is selected as the material. It should be noted that tie rod 10 must be in a taut state, and the connection at both ends must be firm and reliable, without any loosening or slippage.

[0049] like Figure 8 As shown, in order to distribute the counterweight load on the structural beams in two directions and avoid the load acting on the structural slab, preferably, the counterweight bearing member 5 includes two long strip bearing plates arranged perpendicularly to each other, and the width of the long strip bearing plates is not greater than 200mm.

[0050] Specifically, the counterweight bearing component 5 uses two mutually perpendicular long strip bearing plates, which can simultaneously capture and support the structural beams in two directions, evenly distributing the counterweight load onto the two beams and effectively reducing the stress per unit area. According to the relevant requirements of the "Code for Design of Concrete Structures" GB50010 and the "Technical Specification for Concrete Structures of High-Rise Buildings" JGJ3, the width of the frame beam section should not be less than 200mm. This scheme limits the width of the long strip bearing plate to no more than 200mm, which is completely matched with the width of the conventional structural beam 11. This ensures that the counterweight load is strictly limited to the range of the structural beam 11 and does not spread to the roof panel, fundamentally avoiding the roof panel from cracking and breaking under pressure.

[0051] The counterweight bearing component 5 consists of two mutually perpendicular long strip bearing plates, which can form an L-shaped structure or a cross-shaped structure. It is used to connect the structural beams 11 in two directions at the same time, so as to realize bidirectional force and load diversion. The material is steel plate with a thickness of not less than 8mm to ensure sufficient rigidity and strength. It should be noted that the two long strip bearing plates must be perpendicular to each other and firmly welded to ensure that they do not twist or deform under stress.

[0052] The width of the elongated load-bearing plate is set to no more than 200mm to match the minimum cross-sectional width of structural beam 11 specified in GB50010 "Code for Design of Concrete Structures", so that the counterweight load falls entirely within the beam cross-section and does not touch the roof panel. When setting it up, the center line of the elongated load-bearing plate should be aligned with the center line of the structural beam 11 to ensure that the load is accurately transferred to the beam without offset or outward expansion.

[0053] like Figure 8 As shown, in order to strengthen the front support assembly 2, which is the main load-bearing structure, and to enable the load of the front support assembly 2 to be transferred to the structural beams 11 in different directions, preferably, the front support assembly 2 includes a transverse support rod, a longitudinal support rod, and a vertical support rod. The vertical support rod is positioned above the horizontal support rod to support the beam assembly 3; the longitudinal support rod is positioned horizontally and perpendicular to the horizontal support rod; and diagonal reinforcing rods are provided between the horizontal support rod, the longitudinal support rod, and the vertical support rod.

[0054] Specifically, the front support assembly 2 is the main load-bearing structure of the device, and the overturning resistance of the horizontal plate assembly 9 will directly act on it. The spatial frame is formed by the horizontal support rods, longitudinal support rods, vertical support rods and diagonal reinforcing rods, which can significantly improve the strength and rigidity and prevent deformation under stress. At the same time, the horizontal support rods and longitudinal support rods can capture the structural beams 11 in different directions, efficiently transferring the load borne by the front support assembly 2 to the structural beams 11, further reducing the stress on the roof panel and improving the overall stability and safety of the device.

[0055] The transverse support rods are used to capture the structural beam 11 and transfer the load in one direction. They are made of high-strength square steel tubing. When installed, the bottom surface should be flat, allowing direct contact with the structural beam 11. The longitudinal support rods are used to capture the structural beam 11 and distribute the load in another vertical direction. They are made of tubing of the same specifications as the transverse support rods. It should be noted that the longitudinal and transverse support rods are installed perpendicular to each other, forming a two-way beam-capturing support structure. The vertical support rods directly support the beam assembly 3 and are the main load-bearing components. They are made of thick-walled square steel tubing. When installed, they should be kept vertical, with the top tightly fitted to the beam assembly 3. The diagonal reinforcing rods are used to improve the overall integrity and torsional stiffness of the frame. They are welded between the transverse, longitudinal, and vertical support rods. It should be noted that the diagonal reinforcing rods must form a stable triangular structure with full and reliable welds to prevent cracking under stress.

[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
