Description

Technical Field

[0001] The invention provides a horizontal lifeline anti-falling system for renovating an old roof, and relates to the technical field of flat roof safety construction. Background Art

[0002] At present, the Chinese people have increasingly high expectations for their living environment and the quality of their residential communities. Some old urban areas and residential communities cannot meet the residents' requirements in terms of functionality and overall appearance. There are many urban renewal and renovation projects, but most of these old residential communities are built a long time ago. Because the buildings to be renovated are old residential communities with flat roofs, the renovation involves roof construction work such as clearing construction waste such as roof sunshades, demolition and removal of illegal roof structures, waterproofing, foam concrete pouring, insulation construction, and concrete pouring. The construction process is complex and involves many teams. Because flat roof structures cannot be installed with edge protection, the safety of roof construction workers cannot be guaranteed. Some flat roofs have a low wall extending upward from the top. The low wall is less than 1.1 meters high, and a parapet is higher than 1.1 meters. Parapets basically provide safety protection, while low walls do not.

[0003] Construction workers face significant risks of falling while working on rooftops. The specific conditions of the rooftops prohibit structural damage, making it impossible to install expansion bolts, install safety belt attachment points, or establish reliable anchor points for edge protection steel pipes. Some buildings have numerous illegal structures on their rooftops, making construction more complex. Some rooftop renovation projects involve numerous steps and numerous teams of construction workers. Without reliable safety measures, the construction process presents significant safety risks and a greater likelihood of falling while working on the edge. Therefore, practical fall prevention measures are essential.

[0004] Reference document CN217975494U discloses a photovoltaic construction safety rope lock. Although it solves the problem of safety equipment on photovoltaic roofs, the two ends are fixed with an adjustable tooth plate connected in the middle, and are externally connected with a first connecting rod and a second connecting rod to achieve telescopic connection. The upper and lower clamping plates are installed on the outer edge of the roof to achieve external clamping. First, not all roofs have external eaves. Secondly, the eaves rarely extend outward in a rectangular shape, and direct clamping between the upper and lower clamping plates cannot be achieved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a safety system for preventing falling in a low wall of a flat roof, so as to reduce the probability of accidental falling of construction workers.

[0018] Compared with the prior art, the present invention can achieve the following technical effects:

[0019] The present invention not only ensures the safety protection measures for the edge construction of the roof, but also allows construction workers to move horizontally on the roof through the horizontal lifeline, so that they can carry out various roof construction processes normally. At the same time, the material cost of this roof horizontal lifeline anti-fall system is relatively low, and it saves several times the material compared with traditional edge protection facilities. In addition, this method is easy to install and only requires the flat roof to have a certain low wall. There are still many houses with low walls in old communities. The installation cost is almost negligible compared with the labor cost of traditional scaffolders setting up edge steel pipe enclosures. Moreover, this roof horizontal lifeline anti-fall system can also be repeatedly used, with high resource utilization, good economic benefits, and good safety assurance effect and social reputation.

[0020] The present invention installs a safety device on the flat roof, namely a tripod fixed to the low wall.
