What are the roof forms? Classification description

Although there are not many forms of roofs in actual daily life, often including flat roofs or spire roofs, we can find that there are still many forms of modern roofs in China through the analysis of professionals. For details, please refer to the following, or we can combine the buildings that can be excavated around us and analyze them with practical knowledge. Next, let's learn about several main forms of modern building roofs with Bian Xiao. Their shapes are varied, but in general, they cannot be separated from several basic styles.

I. Form of the roof

According to the materials used, roofs can be divided into reinforced concrete roofs, tile roofs, metal roofs and glass roofs. News? The shape and structure of the roof can be divided into flat roof, sloping roof and other forms of roof (suspended cable roof, thin and bright? Roof, arched roof, folding roof, etc. ).

1. Roof platform

Flat roof is easy to coordinate and unify the relationship between buildings and structures, and it is more economical and reasonable, so it is a widely used roof form.

Flat roof is not only a load-bearing component, but also a retaining structure. In order to meet various functional requirements, the roof structure has the characteristics of multi-material superposition and multi-level practice.

Flat roofs should also have a certain drainage slope. Generally, a roof with a slope of 2%-5% is called a flat roof.

2. Slope roof

Slope roof is a traditional roof form in China, which is widely used in residential buildings. Some modern public buildings consider scenery? Sloped roofs are usually used to meet the requirements of environment or architectural style.

The common forms of sloping roofs are: single slope, double slope roof, hard mountain and hanging mountain roof, four-slope sloping mountain and Pangdian roof, round or polygonal pointed roof, etc.

The waterproof materials of sloping roofs are mostly ceramic tiles, and the slope can generally be 10? %- 100? %? , general 10%-20% multi-purpose? On metal plate roofs, more than 20% is used for flat tile and linoleum tile roofs.

3. Other forms of roofs

Civil buildings sometimes adopt other special curved or folding roofs, such as arched roofs, folding roofs and thin-shell roofs. Roof, truss roof, suspended cable roof, grid roof, etc.

Second, the design requirements of the roof

Waterproof requirements

As the envelope structure, the most basic function of the roof is to prevent leakage, so the main task of roof structure design is to solve the waterproof problem. Generally, waterproof roofing materials and reasonable structural treatment are used to achieve waterproof purpose, and appropriate drainage measures are taken according to the situation to quickly drain the accumulated water on the roof to reduce the possibility of leakage. Therefore, the general roof needs a certain drainage slope.

Roof waterproofing is a comprehensive technology, which involves the forms of buildings and structures, waterproof materials, roof slope, roof structure treatment and other issues, and needs comprehensive consideration. The design should follow the principle of "reasonable fortification, combination of prevention and drainage, local conditions and comprehensive treatment".

China current technical specification for roof engineering (GB? 50345-2004) According to the nature, importance, functional requirements and waterproof durability of buildings, roof waterproofing is divided into four grades, and each grade has different fortification requirements.

What I have explained above is about several main forms of modern building roofs. From this, we can know that although there are many roof styles of ancient buildings in China, and they are also very rich with the development and changes of the times, the overall modernity seems to be basically based on several basic styles, so what I mentioned above is the analysis made by Bian Xiao from the perspective of professionals. In addition, we also give examples of graphic introductions and explanatory texts in related fields. Friends who are interested in learning or want to learn from it to provide inspiration may wish to analyze this part of the text in combination with the actual situation, and believe that satisfactory results can be obtained.
