Description

Technical Field

[0001] This utility model relates to the field of construction technology for building decoration engineering, specifically to an installation support platform for roof eaves decorative panels. Background Technology

[0002] With the evolution of architectural design concepts, large public buildings such as airports and landmarks have increasingly higher requirements for both aesthetics and functionality, leading to a significant increase in the demand for multi-layer metal roof eaves decorative panels (especially irregularly shaped panels). Traditional eaves decorative panel installation relies heavily on large cranes, which has significant limitations: on the one hand, hoisting operations are inefficient, and equipment rental and labor costs are high; on the other hand, in high-rise or complex building projects, challenges such as limited hoisting height (crane boom cannot reach the work surface), insufficient operating space (building structure obstruction), and lack of reliable support points are often encountered, drastically increasing the difficulty of decorative panel installation. Furthermore, high-altitude hoisting can easily lead to safety accidents due to swaying and uneven stress.

[0003] The existing support platforms for installing roof eaves decorative panels still have the following problems when in use: most support platforms have poor adaptability and cannot meet the layered installation requirements of multi-layer eaves; some platforms adopt on-site high-altitude assembly methods, which not only prolongs the construction period but also increases the risk of workers falling from heights; at the same time, the existing platforms have insufficient load-bearing stability and safety protection performance, which cannot guarantee the installation accuracy of decorative panels and the safety of construction workers, and are difficult to adapt to the stringent requirements of large public buildings for decoration quality and safety. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an installation support platform for roof eaves decorative panels. By setting up upper, middle, and lower eaves purlins as the basic installation carriers and using prefabricated assembly support platform components, it solves the problems of low efficiency, high cost, and poor adaptability to high-rise / irregular buildings associated with traditional crane hoisting. At the same time, it overcomes the defects of existing support platforms, such as high risk of high-altitude assembly, insufficient load-bearing stability, and lack of safety protection, thus achieving safe, efficient, and precise installation of eaves decorative panels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation support platform for roof eaves decorative panels, comprising upper eaves purlins, middle eaves purlins, lower eaves purlins, and an installation support platform assembly. The installation support platform assembly includes a top load-bearing rod, a top support rod, a bottom grid-shaped support frame, edge sealing rods, roof metal panels, safety uprights, safety wire ropes, and steel scaffolding. The bottom grid-shaped support frame includes a bottom first support rod and a bottom second support rod, which together constitute the bottom grid-shaped support frame for bottom support. The upper, middle, and lower eaves purlins are fixed to the main building structure, providing a reliable installation foundation for the entire support platform and preventing the platform from detaching from the main structure. The bottom grid-shaped support frame, through the cross welding of the bottom first and bottom second support rods, forms a grid-like load-bearing structure, which can evenly distribute the weight of the decorative panels and the load of construction personnel, prevent deformation of the bottom support, and ensure the overall stability of the platform.

[0006] As a further improvement of this utility model: the top load-bearing rod is made of 150×150×4mm steel square tube, and is set along the length direction of the upper eaves purlin, the middle eaves purlin, and the lower eaves purlin, with each span being 5000mm. The top load-bearing rod is welded and fixed to the corresponding eaves purlin. The 150×150×4mm steel square tube has high bending and shear strength, and can bear the main loads on the upper part of the platform, such as the top support rod, safety pole, and the weight of construction personnel. The setting of each span of 5000mm not only ensures the reasonable spacing of the load-bearing rods, avoiding excessive spacing that would cause the rods to bend, but also reduces material waste, taking into account both practicality and economy. The welding and fixing method ensures the firmness of the connection between the top load-bearing rod and the eaves purlin, preventing loosening.

[0007] As a further improvement of this utility model: the top support rod is made of 50×50×4mm steel square tube, and is arranged along its entire length and welded horizontally and vertically to the top load-bearing rod. The overlap length between the top support rods is not less than 3.6m. The 50×50×4mm steel square tube is lightweight and strong, which meets the lightweight requirements of the top support. The continuous arrangement ensures that the top support rod can cover the entire eaves length, providing continuous connection points for the edge banding rod. The horizontal and vertical welding method makes the top support rod and the top load-bearing rod form a right-angle support structure, improving the lateral displacement resistance of the upper frame. The overlap length of ≥3.6m ensures the connection strength of adjacent top support rods and avoids disengagement due to excessively short overlaps.

[0008] As a further improvement of this utility model: the bottom grid-shaped support frame is welded together from a first bottom support rod and a second bottom support rod. Both the first bottom support rod and the second bottom support rod are 50×50×4mm steel square tubes, and the spacing between the steel square tubes is 1200mm. The span of the bottom grid-shaped support frame is 4000mm. The consistent selection of 50×50×4mm steel square tubes facilitates on-site processing and assembly, reducing construction difficulty. The 1200mm spacing between the steel square tubes makes the stress on the bottom frame more even, avoiding local load concentration that could lead to frame damage. The 4000mm frame span is suitable for the eaves width of most large public buildings, eliminating the need for frequent size adjustments and improving construction versatility. Compared with other frame forms, the welded grid-shaped structure has stronger torsional resistance and can effectively resist lateral forces during the installation of decorative panels.

[0009] As a further improvement of this utility model: the edge sealing rod includes horizontal edge sealing rods at both ends and vertical edge sealing rods. A vertical edge sealing rod is installed every 1500mm along the height direction of the bottom grid-shaped support frame. The bottom of the edge sealing rod is vertically welded to the bottom grid-shaped support frame, and the top of the edge sealing rod is welded to the top support rod, thus connecting the bottom support system and the top support structure. The horizontal edge sealing rods prevent tools and materials from falling off the platform edge, and the vertical edge sealing rods installed every 1500mm form a continuous protective barrier, ensuring the safety of construction personnel. The welded connection of the edge sealing rods makes the top support structure and the bottom support system form a whole, preventing them from separating and causing the platform to collapse. It also enhances the overall rigidity of the platform and reduces swaying during operation.

[0010] As a further improvement of this utility model: the roof metal panel is laid flat on the bottom grid-shaped support frame, and the roof metal panel is fixedly connected to the bottom grid-shaped support frame; the safety uprights are vertically welded to the top load-bearing rods, the safety wire ropes are added to the safety uprights and the edge sealing rods, and the steel scaffolding is laid flat between the safety uprights and fixed to the safety uprights; after the roof metal panel is laid flat, a flat working surface is formed, which facilitates the positioning and installation of the decorative panels, and its fixed connection with the bottom frame prevents the metal panel from sliding; the safety uprights and safety wire ropes form a guardrail system, which complies with the safety regulations for high-altitude operations and prevents personnel from falling; the steel scaffolding provides a walking passage for construction personnel, and its fixation to the safety uprights ensures that the scaffolding does not shift, further improving the safety of the operation.

[0011] As a further improvement of this utility model: In the installation support platform assembly, the bottom grid-shaped support frame, roof metal plate, and edge sealing rod are pre-assembled on the ground or bottom platform, and then lifted by a hand-operated hoist to weld the top of the edge sealing rod to the top support rod, completing the overall assembly; the ground prefabrication and assembly method greatly reduces the amount of high-altitude work, reduces the risk of personnel falling, and facilitates the inspection of assembly accuracy on the ground, reducing the cost of later adjustments; compared with large cranes, hand-operated hoists are more flexible in operation, not limited by height or space, and are especially suitable for narrow working environments in high-rise or irregularly shaped buildings, and the equipment cost is lower, which can effectively shorten the construction cycle.

[0012] As a further improvement of this utility model, the steel square tubes of the top load-bearing rod, top support rod, bottom first support rod, bottom second support rod and sealing rod are all coated with an anti-rust coating, which can effectively resist rainwater and moisture erosion, extend the service life of the platform and meet the long-term use needs of outdoor roofs.

[0013] As a further improvement of this utility model: the roof metal plate is made of galvanized metal plate, which has a smooth surface and high strength. This facilitates the sliding adjustment of the decorative panel and prevents the metal plate from rusting. At the same time, the galvanized layer has a certain impact resistance and can protect the bottom frame from damage caused by heavy objects during construction.

[0014] As a further improvement of this utility model, the safety wire rope is made of multi-strand galvanized steel wire rope with a diameter of not less than 12mm and a tensile strength of ≥1800MPa. It can withstand the impact force when construction personnel fall, and the galvanizing treatment improves the corrosion resistance of the wire rope and prevents it from breaking after long-term use.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the structural design of "multi-layer eaves purlins + prefabricated support platform components" perfectly adapts to the installation needs of eaves decorative panels of high-rise and irregularly shaped large public buildings, solving the pain points of traditional cranes such as limited lifting height, insufficient operating space and lack of support points. At the same time, prefabrication and assembly reduce the amount of high-altitude work and reduce construction safety risks by more than 60%.

[0017] 2. In this utility model, the specifications of each component (such as the size, spacing, and overlap length of the steel square tube) are clear and standardized, ensuring the stability of the platform's load-bearing capacity and the accuracy of the installation. The installation error of the decorative panel can be controlled within ±2mm, meeting the stringent requirements of large public buildings for the quality of the decorative surface. At the same time, the use of hand-operated hoists reduces equipment costs by 30%, and prefabrication and assembly improves construction efficiency by 40%, taking into account both practicality and economy.

[0018] 3. In this utility model, the safety pole, safety wire rope, steel plank and edge sealing rod form a multi-layer safety protection system, which fully complies with the safety regulations for high-altitude operations. Furthermore, the rust prevention treatment of each steel component and the galvanized design of the roof metal plate extend the service life of the platform to more than 5 years and reduce the later maintenance costs.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figures 1-4In this embodiment of the utility model, an installation support platform for a roof eaves decorative panel includes an upper eaves purlin 1, a middle eaves purlin 3, a lower eaves purlin 4, and an installation support platform assembly 2. The installation support platform assembly 2 includes a top load-bearing rod 21, a top support rod 22, a bottom grid-shaped support frame 23, an edge sealing rod 24, a roof metal panel 25, a safety upright 26, a safety wire rope 27, and a steel scaffolding 28. The bottom grid-shaped support frame 23 includes a bottom first support rod 231 and a bottom second support rod 232. The bottom first support rod 231... The first support rod 231 and the second support rod 232 together form the bottom grid-shaped support frame 23 for bottom support; the upper eaves purlin 1, the middle eaves purlin 3, and the lower eaves purlin 4 are fixed to the main building structure, providing a reliable installation foundation for the entire support platform and preventing the platform from detaching from the main structure; the bottom grid-shaped support frame 23 forms a grid-like load-bearing structure through the cross welding of the bottom first support rod 231 and the bottom second support rod 232, which can evenly distribute the weight of the decorative panel and the load of construction personnel, prevent the bottom support from deforming, and ensure the overall stability of the platform.

[0027] The top load-bearing member 21 is made of 150×150×4mm steel square tube and is set along the length of the upper eaves purlin 1, the middle eaves purlin 3, and the lower eaves purlin 4, with each span being 5000mm. The top load-bearing member 21 is welded and fixed to the corresponding eaves purlin. The 150×150×4mm steel square tube has high bending and shear strength and can withstand the main loads on the upper part of the platform, such as the top support member 22, the safety upright 26, and the weight of the construction personnel. The setting of each span of 5000mm ensures the reasonable spacing of the load-bearing members, avoids excessive spacing that would cause the members to bend, and reduces material waste, taking into account both practicality and economy. The welding fixing method ensures the firmness of the connection between the top load-bearing member 21 and the eaves purlin and prevents loosening.

[0028] The top support rod 22 is made of 50×50×4mm steel square tube, and is arranged along its entire length and welded horizontally and vertically to the top load-bearing rod 21. The overlap length between the top support rods 22 is not less than 3.6m. The 50×50×4mm steel square tube is lightweight and strong, which meets the lightweight requirements of the top support. The continuous arrangement ensures that the top support rod 22 can cover the entire eaves length, providing a continuous connection point for the edge banding rod 24. The horizontal and vertical welding method makes the top support rod 22 and the top load-bearing rod 21 form a right-angle support structure, which improves the lateral displacement resistance of the upper frame. The overlap length of ≥3.6m ensures the connection strength of adjacent top support rods 22 and avoids disconnection due to excessively short overlap.

[0029] The bottom grid-shaped support frame 23 is welded together from the first bottom support rod 231 and the second bottom support rod 232. Both the first bottom support rod 231 and the second bottom support rod 232 are 50×50×4mm steel square tubes with a spacing of 1200mm. The span of the bottom grid-shaped support frame 23 is 4000mm. The consistent selection of 50×50×4mm steel square tubes facilitates on-site processing and assembly, reducing construction difficulty. The 1200mm spacing of the steel square tubes makes the stress on the bottom frame more even, avoiding local load concentration that could lead to frame damage. The 4000mm frame span is suitable for the eaves width of most large public buildings, eliminating the need for frequent size adjustments and improving construction versatility. Compared with other frame forms, the welded grid-shaped structure has stronger torsional resistance and can effectively resist lateral forces during the installation of decorative panels.

[0030] The edge sealing rod 24 includes horizontal edge sealing rods at both ends and vertical edge sealing rods. The vertical edge sealing rods are installed every 1500mm along the height direction of the bottom grid-shaped support frame 23. The bottom of the edge sealing rod 24 is vertically welded to the bottom grid-shaped support frame 23, and the top of the edge sealing rod 24 is welded to the top support rod 22, thus connecting the bottom support system and the top support structure. The horizontal edge sealing rods can prevent tools and materials from falling off the edge of the platform. The installation of vertical edge sealing rods every 1500mm forms a continuous protective barrier to ensure the safety of construction personnel. The upper and lower welded connection of the edge sealing rods 24 makes the top support structure and the bottom support system form an integral whole, avoiding the platform from collapsing due to the separation of the two, while also enhancing the overall rigidity of the platform and reducing swaying during operation.

[0031] The roof metal panel 25 is laid flat on the bottom grid-shaped support frame 23, and the roof metal panel 25 is fixedly connected to the bottom grid-shaped support frame 23; the safety pole 26 is vertically welded to the top load-bearing pole 21, the safety wire rope 27 is added to the safety pole 26 and the edge sealing pole 24, and the steel scaffolding 28 is laid flat between the safety poles 26 and fixed to the safety poles 26; after the roof metal panel 25 is laid flat, it forms a flat working surface, which facilitates the positioning and installation of the decorative panels, and its fixed connection with the bottom frame prevents the metal panel from sliding; the safety pole 26 and the safety wire rope 27 form a guardrail system, which complies with the safety regulations for high-altitude operations and prevents personnel from falling; the steel scaffolding 28 provides a walking passage for construction personnel, and its fixation to the safety pole 26 ensures that the scaffolding does not shift, further improving the safety of the operation.

[0032] In the installation of support platform component 2, the bottom grid-shaped support frame 23, roof metal panel 25, and edge sealing rod 24 are pre-assembled on the ground or bottom platform. They are then lifted by a hand-operated hoist to weld the top of the edge sealing rod 24 to the top support rod 22, completing the overall assembly. The ground prefabrication method significantly reduces the amount of work at height, lowers the risk of personnel falling, and facilitates the inspection of assembly accuracy on the ground, reducing the cost of later adjustments. Compared with large cranes, hand-operated hoists are more flexible to operate, are not limited by height or space, and are especially suitable for narrow working environments in high-rise or irregularly shaped buildings. Moreover, the equipment cost is lower, which can effectively shorten the construction cycle.

[0033] The steel square tubes of the top load-bearing rod 21, top support rod 22, bottom first support rod 231, bottom second support rod 232 and edge sealing rod 24 are all coated with anti-rust coating, which can effectively resist rainwater and moisture erosion, extend the service life of the platform and meet the long-term use needs of outdoor roofs.

[0034] The roof metal panel 25 is made of galvanized metal sheet, which has a smooth surface and high strength. It facilitates the sliding adjustment of the decorative panel and prevents the metal sheet from rusting. At the same time, the galvanized layer has a certain impact resistance and can protect the bottom frame from damage caused by heavy objects during construction.

[0035] Safety wire rope 27 uses multi-strand galvanized steel wire rope with a diameter of not less than 12mm and a tensile strength of ≥1800MPa. It can withstand the impact force when construction personnel fall, and the galvanizing treatment improves the corrosion resistance of the wire rope, preventing it from breaking after long-term use.

[0036] The working principle of this utility model is as follows: First, after the steel purlins of the building structure are constructed, the top load-bearing rods 21 (150×150×4mm steel square tubes, one span every 5000mm) are welded to the steel purlins as the basic positioning reference, providing core load-bearing support for the upper structure of the platform; then, safety poles 26 are vertically welded on the top load-bearing rods 21, safety steel wire ropes 27 are installed, and steel scaffolding 28 is laid to construct an upper safety operation protection system to ensure the safety of workers when installing decorative panels. Next, the top support rods 22 (50×50×4mm steel square tubes, continuous length, overlap length ≥3.6m) are horizontally and vertically welded to the top load-bearing rods 21 to form the upper support frame; at the same time, on the ground or the bottom platform, the bottom first support rod 231 and the bottom second support rod 232 (50×50×4mm steel square tubes, spaced 1200mm apart, span 4000mm) are installed. The steel scaffolding 25 (mm) is welded into a grid-like structure, and the roof metal panels 25 are laid flat to form the bottom working surface. Edge sealing rods 24 (one every 1500mm vertically) are welded and safety steel wire ropes 27 are added to complete the prefabrication and assembly of the bottom support and protection structure. Finally, the prefabricated bottom first support rod 231 and bottom second support rod 232 grid-like frame is lifted by a hand-operated hoist, so that the top of the edge sealing rod 24 is welded and fixed to the top support rod 22, realizing the connection between the bottom first support rod 231 and bottom second support rod 232 and the top support rod 22, and finally forming a complete and stable installation support platform. Workers can safely and accurately carry out the installation of multi-layer metal roof eaves decorative panels on the working surface formed by the steel scaffolding 28 and the roof metal panels 25. The entire platform ensures the stability of the stress and construction safety through the welding connection and prefabrication assembly of each component, while improving the installation efficiency and accuracy.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
