In recent years, with the rapid improvement of people's living standards, the performance of glass has also put forward higher requirements. Manufacturer enhances the safety of glass and artistic quality, rolled out many new-style glass products, function is powerful, very attractive. For example, the dimming glass that can be used to control diaphaneity is more practical than the traditional frosted glass. Next, please see what kinds of glass lighting roof is divided into to understand the performance design requirements of glass lighting roof.
First, glass lighting top is divided into what kinds
1, monomer glass lighting roof is divided into: single slope, double slope, three slope (Mitsubishi cone), four slope (including four rhombus cone), half garden, 1/4 garden, polycone, garden cone, garden dome, etc.
2, group glass lighting top: is in a roof system, by a number of single glass lighting top in the structural support system combined into a glass lighting top group, its form can be changed at will.
3. Jointed glass lighting roof: it is a whole glass roof and wall system connected by several kinds of glass lighting roof and glass curtain wall with common rods. Hundreds of different shapes of glass lighting roof can be designed.
Two, glass lighting roof performance design requirements
1, strength: refers to the glass lighting roof resistance to wind (snow) load capacity, should pay attention to the wind speed value, the corresponding wind pressure value, and snow pressure value. It depends on the different parts of the country. Namely dead load, wind load and snow load. Snow load is not considered in areas where there is no snow.
2, seismic performance: glass lighting roof under the earthquake, the damage is diverse. The main two aspects, the main support system (well frame, grid frame) damage, glass lighting roof natural damage. Some of the supporting systems are reinforced concrete frames and some are spherical grids, whose seismic performance varies with design. Another kind is the main supporting system in good condition, aluminum alloy glass daylighting roof during the earthquake destroyed itself, it is glass daylighting roof itself factors, it is from the glass daylighting roof itself seismic design consideration, main consideration glass daylighting roof and the connection of the reliability of the main bearing body, and to consider the glass daylighting disobey one's superior extrusion deformation.
3. Air tightness: the sealed glass daylighting top has strict requirements on air tightness. Air permeability indicates the sealing ability of the glass daylighting top under the closed state of all parts of the daylighting top.
4, water tightness: the water tightness of the glass lighting top refers to the ability of the glass lighting top to prevent rain leakage inside under the action of wind and rain or snow melting, roof water, which is related to the wind speed of the storm, rainfall and snow melting water volume. The condensation on the inside of the glass ceiling is a very vexing problem. Dew dripping down from the ceiling of the light is a great nuisance. Therefore, the slope design slope of the glass lighting roof should be carefully considered to prevent condensation and dripping, but leakage along the glass. The rod of the glass lighting top should have a sink, and the dew falling along the glass will be collected and flow to the outdoor along the sink, and dew calculation should be made in the design.
Daylighting top is the design commonly used in shopping malls, airports and office buildings, and the common sun room in our life is the same, in the price skyrocketing in the city of land, with a good view of good lighting of the small attic living sun room, let a person's happiness and a qualitative improvement.
