Description

Reinforcing waterproof system for peripheral roof of skylight

Technical Field

The utility model belongs to the technical field of building structure waterproofing, and particularly relates to a reinforcing waterproof system for a peripheral roof of a skylight.

Background

The ventilating skylight installed on the roof of the factory building has the working principle that the ventilating and smoke discharging effects are achieved by means of natural air flowing, so that the ventilating skylight is also called as a self-flowing type ventilator. Many industrial plants, especially color steel plate buildings, have poor heat dissipation conditions and are sultry and abnormal in summer, so that the working efficiency is low and the product quality is reduced. The ventilation skylight has good effect on ventilation and exhaust of the industrial factory building, improves the ventilation environment of the factory building, enables air circulation to be smoother, and can ensure safety of staff and equipment in the factory building. The ventilation skylight is reasonably arranged and installed, so that the indoor air quality can be effectively improved, a comfortable working environment is provided, and the working efficiency is improved. Meanwhile, the installation of the roof ventilation skylight has the function of safety prevention and control, and in many fire accidents, people are often choked by thick smoke, for example, the installation of the roof ventilation skylight can rapidly discharge a large amount of thick smoke, and more escape spaces are created, so that the function of eliminating smoke is exerted.

The general ventilation skylight is an open-close type roof ventilation skylight, the open-close type roof ventilation skylight is provided with a valve plate, the valve plate is controlled by manual, electric and other modes, and the indoor ventilation smoke discharge amount can be regulated by controlling the opening and closing angle of the valve plate. The valve plate control mode of the open-close type roof ventilation skylight can also realize fire-fighting linkage, and the open-close type ventilation skylight can be controlled by modes such as temperature sensing, smoke sensing, rain sensing or manual operation. For example, when disaster warning occurs, the ventilation skylight control system can perform linkage induction, automatically open or close the skylight, and because the skylight is more in self-configuration components and larger in counterweight, and has higher requirements on safety and stability of an operation environment, after the ventilation skylight is installed, the ventilation skylight is easy to leak at a connecting node of the ventilation skylight and a steel structure roof, once the conditions of roof leakage and unstable supporting strength occur, the stability of the whole structure of a factory building can be damaged due to the lack of reinforcement and waterproof local treatment of the circumferential roof at the position where the skylight is located.
