1. What's the difference between a ceiling with columns and a ceiling without columns?
1. The difference between a ceiling with columns and a ceiling without columns:
A canopy with columns is a platform with columns. Pillarless canopy refers to a canopy without columns on the platform, that is to say, there are no columns on the platform, but strictly speaking, it belongs to a new type of canopy with columns.
2. Non-pillar canopy is a new trend in the development of railway station platform canopy in China at this stage, so is there really no pillar? The answer is no, how can a canopy without columns be stressed and supported? Strictly speaking, the pillar-free canopy refers to the platform pillar-free canopy, which is a new design to reduce traffic obstacles. The difficulty lies in the span of the crown. At present, there are also some new awnings whose platform columns are not on the platform, but on the track subgrade, which is also called column-free awnings, but strictly speaking, they belong to new awnings with columns.
3. Crown form
(1) small canopy.
Such as: cantilever canopy, hanging canopy;
(2) Big crown.
Such as: awnings supported by walls or columns;
(3) finalize the design canopy.
Such as: new building materials, patented design, large-scale production in factories.
Second, the area calculation of canopy with columns
According to the Code for Calculation of Building Area of Building Engineering (GB/T? 50353-20 13)3.0. 16? It is stipulated in the clause that the construction area of column awning should be calculated as 1/2 of the horizontal projection area of its structural plate.
Calculated construction area of a column-free awning connected to a building:
According to the construction area calculation rules: the width of awning is greater than 2. 10m or less than 2.l0m, and the width exceeding 2. 10m shall be calculated as 1/2 of the horizontal projection area of awning structural plate; Less than or equal to 2. 1 m, the construction area is not calculated.
Brief introduction of building area:
Building area, a real estate term, is directly related to the calculation of usable area and utilization rate. According to different countries and regions, its definition and measurement standards may not be consistent. The building area is generally larger than the usable area. Building area is an important technical and economic index in the field of construction engineering, and it is also one of the important indexes of national macro-control. The construction area refers to the horizontal area of the periphery of the structure above the external wall of the building, which is a physical quantity index reflecting the construction scale in square meters.
Everyone here today has professional information about the column canopy, from which we can know that it can not only play the role of shading from the sun and rain, but also play the role of support. In addition, there are many options for column tents on the market. Qualified products are often made of quantitative materials and have professional structural design, which can play a safe role. We should start with this standard and make a comparison, and Bian Xiao also suggested that consumers and friends can know the goods purchased by the column canopy in advance.
