What are the practical quadratic construction formulas? 1. Buildings are divided into civil buildings and industrial buildings.
2. Civil buildings are divided into residential buildings (houses, apartments, dormitories) and public buildings (libraries, stations, office buildings).
3. Residence: 1-3 floors are low-rise residences, 4-6 floors are multi-storey residences, 6-9 floors (or not more than 27m in height) are medium-high-rise residences, and 10 floors and 10 floors or more than 27m are high-rise residences.
4. For buildings other than residential buildings, those with a height greater than 24m are single-storey or multi-storey buildings, those with a height greater than 24m are high-rise buildings (excluding single-storey buildings with a height greater than 24m), and those with a height greater than 100m are super-high-rise buildings.
5. Buildings are divided into wood structure, brick-wood structure, brick-concrete structure, reinforced concrete structure and steel structure according to materials.
6. The building consists of structural system, enclosure system (roof, external wall, doors and windows) and equipment system (water supply and drainage system, power supply system, heating and ventilation system-water heating and electricity).
7. Influencing factors of building structure: load factors, environmental factors (natural factors, human factors), technical factors (building materials, building structure, construction methods-mandatory) and building standards (cost standards, decoration standards, equipment standards).
8. Architectural design principles: firm and practical (sufficient strength, rigidity and integrity), advanced technology, reasonable economy and elegant appearance.
9. Implement building height control, which is determined according to the height from the outdoor ground of the building to the highest point of buildings and structures.
10. If building height control is not implemented, it shall be calculated according to the height from outdoor ground to its surface or parapet top; The top of the slope shall be based on the average height from the outdoor ground of the building to the cornice and roof, excluding the staircase protruding locally (not exceeding 1/4).
What are the subjects of the Second Construction Examination? The subjects of the Second Construction Examination include "Construction Engineering Regulations and Related Knowledge", "Construction Engineering Management" and "Practice" (architecture, municipal administration, electromechanical, water conservancy and highway). If you want to get the certificate in one fell swoop, you need some time to review and study.
The second-level constructor exam is a qualification certificate and a relatively high evaluation of the major. Secondly, the builder's second-level exam is a relatively professional exam. Without a certain foundation and a certain degree of review efforts, it is not easy to succeed.
