Description

Technical Field

[0001] This utility model belongs to the field of roof maintenance technology, specifically relating to a mobile metal roof maintenance platform that is small in size, light in weight, low in cost, easy to construct, and has little impact on the building facade. Background Technology

[0002] Steel-structured metal roofs are widely used in industrial and civil buildings. Because metal roofs typically house skylights, ventilation equipment, photovoltaic solar panels, and waterproofing and insulation systems, regular maintenance and repair of these devices are essential. According to the national standard GB 50896-2013, "Technical Specification for Application of Corrugated Metal Sheets in Engineering," corrugated metal sheet systems should include access routes and maintenance access points. Roof maintenance access provides a convenient and safe way for workers to access various locations on the roof for necessary inspection and maintenance. Therefore, metal roof maintenance access is a crucial facility for ensuring the long-term safe operation of the roof system, and its design must balance safety, waterproofing, durability, and ease of construction.

[0003] Currently, maintenance access routes for metal roofs typically consist of a long, continuous metal pedestrian walkway with metal railings on both sides for protection. Because metal roofs are usually quite large, this results in excessively long access routes, making it difficult to transport them to the site after factory fabrication. Therefore, most maintenance access routes in the industry are constructed by welding individual components on-site. However, these components are still quite heavy, causing difficulties for on-site installation, increasing material and construction costs, and the railings along the entire length of the access route also affect the aesthetics of the building facade, leading to higher maintenance and upkeep costs in the long run.

[0004] In existing technologies, to address the shortcomings of long metal pedestrian walkways, one approach involves installing several access gates covered by aluminum alloy manhole covers at intervals on the metal roof. Maintenance and repairs are performed by climbing through these gates from inside the building. While this method offers flexibility and doesn't affect the building's aesthetics, the small coverage area limits its application to single-point maintenance of pipes and equipment. Frequent opening can lead to seal failure, and the need to climb each gate individually presents safety hazards and is physically demanding. Another approach involves connecting the main frame to the building's steel structure, with the supporting frame insulated with rock wool and edged with steel plates. A hydraulically operated manhole cover is installed at the top, and water channels and waterproof membrane are installed around the perimeter. This inclined manhole system ensures convenient maintenance and repair while maintaining aesthetics and functionality. However, due to its complex installation, requiring a professional construction team and incurring high costs, this method is primarily used for metal roofs of public buildings such as airport terminals and stadiums, and is unsuitable for metal roofs of conventional industrial and civil buildings.

[0005] Therefore, it is of great significance to design a metal roof maintenance platform that is small in size, light in weight, low in cost, easy to construct, has little impact on building facades, and can be widely used in industrial plants, warehouses and large public buildings. Utility Model Content

[0006] In order to solve the problems mentioned in the background art, the present invention provides a mobile metal roof maintenance platform that is small in size, light in weight, low in cost, easy to construct, and has little impact on the building facade.

[0007] The mobile metal roof maintenance platform of this utility model is implemented as follows: it includes purlins, underlay purlins, and metal roof panels. The underlay purlins are fixed at intervals to the top of the purlins, and the metal roof panels are fixed to the underlay purlins. It also includes several roof clamps, at least two tracks, and a maintenance vehicle. The roof clamps are vertically fixed to the top of the metal roof panels above the underlay purlins. The tracks are horizontally fixed to the top of the several roof clamps. The extension direction of the tracks is perpendicular to the tilt direction of the metal roof panels. The maintenance vehicle includes a maintenance platform and rollers located at the bottom of the maintenance platform near the four corners. The rollers are rotatably mounted on the tracks.

[0008] Furthermore, the maintenance platform includes a base plate and railings. The base plate is laid on the bottom surface of the maintenance platform, the rollers are arranged below the base plate near the four corners, the railings are vertically fixed around the base plate, and an openable maintenance door is provided on the railing on at least one side of the base plate.

[0009] Furthermore, a support frame is fixedly installed at the bottom of the base plate, the bottom of the railing is fixedly connected to the support frame, and the rollers are located near the four corners of the support frame.

[0010] Furthermore, the base plate is an aluminum alloy patterned plate, a stainless steel patterned plate, or a phosphated patterned steel plate, and the railing is an aluminum alloy railing or a stainless steel railing.

[0011] Furthermore, the top of the roller bracket is fixedly connected to the support frame; or the roller bracket is fixedly connected to the base plate or support frame via a connecting plate, wherein the connecting plate has an inverted frustum structure and its top is embedded in the base plate, and the roller bracket is fixed by bolts that penetrate the bottom platform of the connecting plate.

[0012] Furthermore, the roof clamp is made of aluminum alloy or stainless steel and is clamped at the metal roof panel locking edge position on the upper part of the purlin, and the track is fixedly set on the horizontal support surface at the top of the roof clamp.

[0013] Furthermore, the track has a frame-shaped structure with an open upper section, and the rollers at the bottom of the maintenance platform are rolled inside the cavity of the track. The width of the upper opening of the track is smaller than the width of the lower cavity.

[0014] Furthermore, the length of the roof clamp at the lower part of the metal roof panel slope along the height direction is longer than the length of the roof clamp at the upper part of the slope, and the upper surfaces of each track on the metal roof panel are on the same horizontal plane.

[0015] Furthermore, a fixing ring is fixedly installed on the outside of the roof clamp or the outside of the track, and a hook that cooperates with the fixing ring and can be tightened is provided on the maintenance platform.

[0016] Furthermore, at least one of the two rollers at the bottom of the maintenance platform is equipped with a drive motor or connected to a manual chain drive pair. The manual chain drive pair includes a rotating wheel movably disposed above the maintenance platform, a handle fixed on the rotating wheel, a main sprocket fixed coaxially with the rotating wheel, a driven sprocket fixed coaxially with the roller, and a chain sleeved on the main sprocket and the driven sprocket.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model addresses the shortcomings of existing technologies by installing a track supported by purlins and lining purlins on the metal roof panel, and setting up a maintenance cart on the track to replace the traditional long maintenance passage. Because each maintenance cart is small in size and uses lightweight materials such as aluminum alloy and stainless steel to make the base plate, railings and other components, it not only reduces the overall weight, but also facilitates transportation and on-site installation after factory processing; it can also be flexibly and conveniently moved to the maintenance position for construction as needed; and because the track is close to the metal roof panel and the maintenance cart is small in size, railings are only set around the maintenance platform of the maintenance cart, so the impact on the building facade can be significantly reduced. It can be widely used for the inspection and maintenance of metal roofs of industrial plants, warehouses and large public buildings.

[0019] 2. The maintenance platform structure of this utility model is relatively simple, which not only reduces the amount of materials used, but also eliminates the need for complex processing technology and professional construction teams, thus reducing construction costs. Compared with the existing long maintenance channel system, the material cost, construction cost and subsequent maintenance cost of the entire maintenance platform are all lower.

[0020] 3. This utility model innovatively adopts a modular design. Components such as roof clamps, tracks, and maintenance carts can be prefabricated in the factory. On-site, it is only necessary to fix the track to the purlin using the roof clamps and then place the maintenance cart on the track. No welding is required on-site, so the installation is convenient. Compared with the traditional method of welding individual parts on-site, it can greatly improve construction efficiency.

[0021] 4. This utility model sets the track perpendicular to the inclined direction of the metal roof panel, and the maintenance vehicle moves horizontally along the track, which can flexibly cover different areas of the roof; moreover, the rollers at the bottom of the maintenance vehicle can move freely, which can meet the maintenance needs of different locations, and the maintenance vehicle is driven by a drive motor or a manual chain drive pair, which improves the convenience and efficiency of movement.

[0022] 5. This utility model eliminates the risk of personnel falling by setting railings around the maintenance platform and providing an openable maintenance door. In particular, the fixing rings that cooperate with the hooks of the maintenance platform are set on the outside of the roof clamps or the outside of the track to fix the maintenance vehicle during maintenance, preventing slippage and overturning, thus further improving construction safety. At the same time, by setting the upper open frame structure track and rolling the rollers inside the cavity of the track, the stability of the maintenance vehicle's movement can be guaranteed, and lateral overturning of the maintenance vehicle can be prevented during movement.

[0023] 6. The roof clamp of this utility model is clamped at the locking edge of the metal roof panel on the upper part of the purlin. Compared with the traditional through clamp fixation, it will not damage the original waterproof structure of the roof, fundamentally eliminating the risk of leakage caused by the opening, and can maintain the waterproof performance of the metal roof. Moreover, it does not affect the free expansion and contraction of the metal roof under temperature changes, and can avoid the accumulation of thermal stress and deformation damage caused by traditional fixing methods.

[0024] In summary, this utility model can effectively solve the problems of large steel consumption, heavy load, high cost, and the impact of railings on the aesthetics of the building facade of traditional metal roof maintenance access channels, as well as the difficulty of later maintenance and upkeep. Overall, it has the characteristics of small size, light weight, low cost, convenient construction, and minimal impact on the building facade. Attached Figure Description
