Description

Technical Field

[0001] The utility model relates to the technical field of edge protection devices, in particular to a reusable parapet edge protection device. Background Technique

[0002] Under the social environment where the country vigorously advocates energy conservation, environmental protection and sustainable development, the development and application of green construction technologies become increasingly important. During the construction process of building construction projects, during the construction of non-accessible roofs, edge protection railings are an essential measure. Traditional protection uses steel pipes to build floor-standing double-row scaffolding or cantilever scaffolding protection measures. Both the floor-standing double-row scaffolding and the cantilever scaffolding need to be not less than 1 meter higher than the parapet top, resulting in a large amount of consumables, a long construction period for the roofing project, a long rental time for steel pipe materials, and high costs. In this context, it is particularly important to invent a detachable, reusable, material-saving, environmentally friendly, lower amortization cost and easy-to-operate parapet edge protection device. Content of the Utility Model

[0003] To overcome the technical defects of the existing floor-standing double-row scaffolding or cantilever scaffolding, which have a large amount of consumables and a long construction period, resulting in a long rental time and high costs, the utility model provides a reusable parapet edge protection device.

[0004] The utility model provides a reusable parapet edge protection device, which comprises a plurality of groups of support units. Each support unit includes an inverted U-shaped clamping plate, a seamless square tube and a support bolt. The inverted U-shaped clamping plate is clamped downward with its opening facing downwards on the upper side of the parapet coping. The seamless square tube is fixedly welded vertically to the top of the inverted U-shaped clamping plate. A threaded hole is formed in the side wall of the inverted U-shaped clamping plate close to the roof structure. The support bolt is connected to the side wall of the inverted U-shaped clamping plate through the threaded hole. The support bolt is perpendicular to the side wall of the inverted U-shaped clamping plate and the wall surface of the parapet. A steel gasket is welded to one end of the support bolt close to the parapet. A rubber gasket is provided between the steel gasket and the wall surface of the parapet. A tightening nut is in threaded fit with the support bolt between the side wall of the inverted U-shaped clamping plate and the wall surface of the parapet. The seamless square tubes between adjacent support units are connected by a steel tube in the horizontal direction. There is an edge extending beyond the wall surface of the parapet on the parapet coping on one side of the roof structure. When the inverted U-shaped clamping plate is clamped downward on the parapet coping, the support bolt is located below the edge of the parapet coping. The side wall of the inverted U-shaped clamping plate that is not connected to the support bolt is completely attached and tightened to the wall surface of the parapet and the side wall of the parapet coping. When the tightening nut on the support bolt is adjusted towards the inner side wall of the inverted U-shaped clamping plate, the inverted U-shaped clamping plate can be firmly fixed to the parapet. After the inverted U-shaped clamping plates of adjacent support units are firmly connected, the seamless square tubes between adjacent support units are sequentially connected by steel tubes, so that a firm protection device can be formed. This protection device is easy to disassemble, reusable, convenient to install, and has a low cost. Moreover, by adjusting the support bolt, it can adapt to parapets of different thicknesses, and has good versatility. After being manufactured and produced once, it can be recycled and reused, avoiding the high cost of renting steel tubes during long-term construction.

[0005] Preferably, at least one through hole for passing the steel tube is formed in the seamless square tube. The axial direction of the through hole is parallel to the extending direction of the parapet. The steel tube and the seamless square tube are fixedly connected by a fastener. Such a setting has a reasonable structure and is convenient for installation and disassembly.

[0006] Preferably, a flame-retardant dense mesh is hung outside the support unit. This is set according to actual needs. Finally, after the construction of the roof insulation, waterproofing, protective layer and roof lightning protection grounding is completed, the steel tube and the loosened support bolt are removed to disassemble the support unit, so that it can be quickly put into use in the next building.

[0007] The technical solution provided by the present utility model has the following technical effects compared with the prior art: This protective device is easy to disassemble, reusable, convenient to install, and has a relatively low cost. Moreover, by adjusting the support bolts, it can adapt to parapets of different thicknesses, with good versatility. After being manufactured and produced once, it can be recycled and reused, avoiding the high costs incurred by renting steel pipes during long-term construction. It is suitable for construction sites of housing buildings and industrial factories. The device is environmentally friendly, has high construction efficiency and high stability, ensuring construction quality and safety. This not only saves production costs for enterprises, but also reduces construction costs; this protective device can finally be depreciated, which can save costs; it has good promotion and practical value, and good economic benefits will be generated after extensive promotion and application.
