Description
Technical Field
[0001] This utility model belongs to the field of building construction technology and relates to a modular safety support device for high-altitude operations on pitched roofs. Background Technology
[0002] High-altitude operations on pitched roofs (such as waterproofing and photovoltaic panel installation) require high stability, portability, and roof protection for safety support devices. Traditional methods often rely on scaffolding or simple support tools, which have significant shortcomings: First, they are inefficient and costly. Scaffolding requires on-site assembly, involves numerous parts, and is time-consuming and labor-intensive to erect at heights, resulting in high labor and equipment rental costs, especially for complex pitched roofs. Second, they offer insufficient roof protection. The rigid support surface is in direct contact with the roof, making it prone to scratches or damage to the waterproofing layer due to concentrated pressure. Furthermore, the fixed coefficient of friction means that anti-slip performance depends on rigid fixation, posing a risk of slippage. Third, they lack portability and reusability. Traditional devices are heavy, have low modularity, are difficult for a single person to move, and metal components are prone to corrosion, resulting in a short lifespan, insufficient reusability, and poor environmental performance. Fourth, they have safety limitations. Existing support surface anti-slip designs are simplistic and lack adaptive pressure adjustment mechanisms. The stability of the work platform fluctuates with load changes, especially on sloping roofs, where it is prone to sideslip or overturning, threatening personnel safety.
[0003] To address the aforementioned issues, there is an urgent need for a lightweight support device that combines efficient installation, roof protection, self-adaptive anti-slip properties, and high reusability to meet the comprehensive safety, economic, and environmental requirements of modern high-altitude operations. Summary of the Invention
[0004] This utility model provides a modular safety support device suitable for high-altitude operations on sloping roofs, aiming to build a stable and reliable working platform for scenarios such as waterproofing repairs and photovoltaic panel installation. The device adopts a trapezoidal prism structure, with the overall arrangement in a longitudinal horizontal manner, forming a stable and anti-slip support system after being arranged. Its cross-section is designed with a geometric shape that is narrower at the top and wider at the bottom, with the hypotenuse and bottom surface forming a suitable tilt angle, which not only fits the tilt characteristics of the sloping roof, but also ensures the stability of the working platform and the comfort of the person standing by optimizing the height and width ratio.
[0005] The main body of the device is made of engineering plastic, integrally molded from high-strength composite plastic. The material combines lightweight and high strength. A groove is cut into the lower part of the main body; this groove design reduces weight while the internal reinforcing structure further enhances load-bearing capacity, meeting the load requirements for personnel standing and temporary stacking of small materials during high-altitude operations. A non-slip surface layer is provided on the waist area, using surface texture treatment or composite elastic materials to form a safe working surface of suitable width, effectively preventing personnel from slipping while providing stable space for tool placement.
[0006] The bottom surface adopts an innovative soft-hard composite structure: the lower layer is a soft anti-slip foam made of replaceable flexible material, which is in direct contact with the roof. Its soft texture can closely conform to the slope curve and deform under working load to increase the contact area. This not only improves the anti-slip performance of the device through initial friction, but also avoids damage to the roof waterproofing layer by the hard material. The upper layer is a rigid embedded foam, which is embedded in the main groove at the bottom of the main body, forming a fixed connection with the main groove and forming a pressure transmission system with the lower soft material. When the device is under load, the upper rigid foam evenly distributes the pressure to the lower soft foam. Through the synergistic effect of the soft and hard materials, a self-stabilizing anti-slip support effect that increases with pressure is formed, which significantly improves the device's anti-slip ability on slopes.
[0007] Modular design is one of the core advantages of this device. Each unit is lightweight and appropriately sized, making it easy for a single person to carry and quickly assemble and disassemble. It can be flexibly combined and deployed according to the roof slope and work area. The engineering plastic body has strong weather resistance, and combined with a replaceable bottom foam layer, it effectively extends the service life of the device, enabling long-term reuse of structural components, reducing construction costs and material waste, and conforming to the concept of green construction.
[0008] Compared to traditional high-altitude work support equipment, this device, through structural innovation and material optimization, solves problems such as easy slippage of support devices, easy damage to the roof, and inconvenience of disassembly and assembly in sloping roof environments while ensuring operational safety. Its integrated molding process and composite structure design not only meet the reliability requirements of engineering sites but also improve construction efficiency through modularity, providing a new solution for high-altitude operations on sloping roofs that combines safety, economy, and environmental protection.

[0010] The components in the figure include: high-strength composite plastic (1), anti-slip tread layer (2), soft anti-slip foam (3), and rigid foam (4). Among them, the high-strength composite plastic (1) trapezoidal prism is placed horizontally on the pitched roof (5) at certain intervals during use. The angle between its waist surface and bottom surface is close to the slope of the pitched roof (5) to form a suitable tilt angle. The anti-slip tread layer (2) is symmetrically pasted on the two waist surfaces of the high-strength composite plastic (1). The two ends of the high-strength composite plastic (1) are provided with handle holes (11) and have square main grooves (12) inside for embedding rigid foam (4). The square main grooves constitute the main groove. The rigid foam (4) is embedded in the square main grooves (12) of the high-strength composite plastic (1) to form an embedded connection. The bottom of the rigid foam (4) is bonded to the soft anti-slip foam (3) as a whole. The soft anti-slip foam (3) is made of flexible material and has an anti-slip layer (31) on the bottom surface. During use, the soft anti-slip foam (3) and the anti-slip layer (31) can be replaced according to the actual wear. The high-strength composite plastic (1) is provided with reinforcing ribs to form a reinforced structure and improve the structural strength. Detailed Implementation

[0013] The present invention will now be described in detail with reference to the embodiments and accompanying drawings. Example
[0014] In the waterproofing construction of a 30° cast-in-place concrete pitched roof of a commercial building, this modular support device played a crucial role. The roof utilizes a single-layer polymer membrane process, with a steep slope requiring work at height. Traditional support equipment is prone to slippage and may damage the waterproofing layer. However, the device's trapezoidal prism structure is adapted to the 30° roof slope, with the waist and bottom surfaces forming a matching angle, precisely conforming to the slope. Multiple units arranged together form a stable support system, providing a stable working platform for construction workers. The main body of the device is made of engineering plastic, constructed from high-strength composite plastic, with each unit weighing only 5kg. Workers can easily move it using the handles at both ends. Horizontally arranged along the roof at 1.5m intervals, it forms a continuous anti-slip working zone. Each row of devices is approximately 60cm wide, sufficient for a single person to stand and temporarily place membrane, scrapers, and other tools, avoiding the inconvenience of frequent relocation of traditional scaffolding.
[0015] During construction, the anti-slip surface layer on the waist of the device uses a textured elastic material with a rough yet elastic surface. Even with residual water stains on the roof, the wet friction coefficient remains above 0.6, effectively preventing people from slipping. The soft-hard composite structure of the bottom surface is particularly crucial: the lower layer of soft anti-slip foam is a flexible material that adheres tightly to the concrete base. Through flexible deformation, it fills the tiny unevenness, protecting the waterproof membrane from rigid compression while increasing initial contact friction. The upper layer of rigid foam is embedded in the main square groove, firmly connected to the groove, and evenly transfers the construction load to the lower soft material, forming a "pressure-enhanced anti-slip support." Reinforcing ribs are added inside the main structure to enhance structural strength while maintaining lightweight design. When people step on it, the soft foam slightly compresses, and the contact area expands with increasing pressure, generating a frictional self-locking effect. Even on a 30° slope, the device does not slip.
[0016] During construction, operators stand on the anti-slip surface of the device and unfold the polymer roll material vertically along the roof. They use a scraper to press and release air. After each section is laid, the device can be quickly moved to the next area, with each move taking less than 10 seconds – nearly twice as efficient as traditional scaffolding. At complex locations such as gutters and corners, the spacing between devices can be flexibly adjusted or individual devices can be placed. Even after repeated use and wear, the soft foam can be replaced individually within 30 seconds without disassembling the main body, effectively extending the lifespan of the engineering plastic structure and preventing overall equipment damage. Notably, no damage to the roll material from sharp objects occurred during the entire construction process, significantly improving the protection of the finished product.
[0017] Compared to traditional steel pipe scaffolding, this device eliminates the need for on-site assembly and bolt fixing, shortening the construction cycle of a single roof by two days and reducing labor costs by 30%. Its modular design enables efficient material reuse; the main engineering plastic can be reused more than 50 times, ensuring a long service life; the soft foam uses environmentally friendly EVA flexible material, which can be recycled and reused after disposal. The construction process generates zero construction waste, fully complying with green construction standards. In 30° pitched roof environments, the device, through optimized synergy of structure and materials, relying on the main channel, reinforcing structure, and embedded connections, balances safety, construction efficiency, and environmental requirements, providing a replicable high-altitude operation support solution for similar projects. It is particularly suitable for scenarios such as waterproofing of cast-in-place concrete roofs with slopes of 20-45° and photovoltaic installations, demonstrating significant engineering application value.
