The installation of Fire Smoke Exhaust Skylight requires consideration of multiple building structural conditions, which are critical to ensuring that the skylight can properly perform its smoke exhaust function and the overall safety of the building.
The first is the load-bearing capacity of the roof. The Fire Smoke Exhaust Skylight itself has a certain weight, including components such as window frames, window sashes, and drive devices. In actual use, it is also necessary to consider external forces such as wind loads and snow loads that may be borne. For example, in some northern regions, the snow is thick in winter, and the weight of snow on the roof will exert great pressure on the skylight. The roof structure of the building must be strong enough to withstand these static and dynamic loads. Generally speaking, the load-bearing capacity of the roof needs to be evaluated before installation, and structural calculations are performed to determine whether the roof needs to be reinforced. If the roof is a light steel structure, it may be necessary to increase the specifications of the steel beams or increase the spacing of the steel beams to meet the load-bearing requirements after the skylight is installed.
The second is the slope and shape of the roof. Different roof slopes and shapes have a great impact on the installation method and performance of the Fire Smoke Exhaust Skylight. For flat roofs, installation is relatively simple, but special attention should be paid to drainage to prevent rainwater from accumulating around the skylight. For sloping roofs, the installation angle of the skylight needs to be adapted to the roof slope to ensure good sealing and drainage performance. For example, when installing the Fire Smoke Exhaust Skylight on some double-slope roofs, it is necessary to adjust the installation frame of the skylight according to the angle of the roof slope so that the skylight fits tightly with the roof slope to prevent rainwater leakage. In addition, for some complex special-shaped roofs, such as domes and folded plate roofs, the installation of the Fire Smoke Exhaust Skylight requires the customization of special mounting brackets and sealing structures to adapt to the special shape of the roof.
The next is the spatial layout and height of the building. The installation location of the Fire Smoke Exhaust Skylight should take into account the spatial layout inside the building to ensure that it can effectively exhaust smoke. Generally speaking, skylights should be installed above areas where smoke is easy to gather, such as atriums, corridor intersections, etc. At the same time, the height of the building will also affect the smoke exhaust effect of the skylight. In high-rise buildings, due to the obvious chimney effect, it is necessary to reasonably utilize this effect to install skylights so that smoke can be discharged smoothly. In addition, it is also necessary to consider obstacles inside the building, such as beams, columns and other structures, to prevent them from affecting the opening of the skylight and the smooth flow of smoke exhaust channels.
In addition, the fire partition and smoke partition settings of the building will also affect the installation of Fire Smoke Exhaust Skylight. The installation of skylights should comply with the requirements of the division of fire partitions and smoke partitions, cannot destroy the integrity of the partitions, and ensure that in the event of a fire, the smoke in each partition can be effectively discharged through the corresponding skylight.
