Q: What are the symbols in architectural drawings?
Answer: In architectural design, L stands for beam, ll stands for continuous beam, ql stands for ring beam, jl stands for foundation beam, tl stands for ladder beam, dl stands for ground beam, Z stands for column, gz stands for constructional column, kz stands for frame column, M stands for door and C stands for window. @ indicates rebar spacing and rebar model.
1, a formal architectural design should have the signature of the designer, the signature of the person in charge of the architectural drawings, the signature of the reviewer, the signature of the proofreader, and the seal and the registered practice seal.
2. In architectural design drawings, the length is generally in mm, unless otherwise specified; Pay attention to the description of building materials and other drawings when looking at the picture. In the description of building materials, the methods used for design are marked in front of each item. What is not ticked is not the design practice.
3. Architectural design: c20 reinforced concrete jl(240400) with 4 windings 16 and 6 @ 200 hoops. The foundation beam of reinforced concrete structure with strength C is 240mm wide and 400mm high. It is equipped with four main steel bars with a diameter of 16mm (16 mm), and a rectangular ring of steel bars with a diameter of 6 mm is hoop every 200 mm (the rectangular ring is about 340±350mm long and about 180mm 190mm wide).
4. For example, in architectural design, c20 concrete column (240240) is equipped with 4 12 hoop] 6 @ 200. Among them,] 6 @ 200 is not standard and should be 6 @ 200. It is interpreted as: a c20-strength small beam of reinforced concrete structure, with a section length of 240mm and a width of 240mm, is equipped with four main bars with a diameter of 12mm (12mm), and a rectangular steel mesh with a diameter of 6cm is hoop every 200mm. The height of the column depends on the height of the floor marked by the project minus the height of the ring beam and the thickness of the panel, because the ring beam and the panel are poured together.
5. For example, m5 cement mortar is used to build mu 10 shell lime-sand brick in the architectural design. M5 represents the strength grade of cement mortar and mu 10 represents the strength grade of lime-sand brick. Mu 10 represents the average compressive strength of lime-sand brick 10mpa.
6.ql stands for ring beam and ring beam, which is usually used in brick-concrete building structure (mixed structure), that is, the wall is built first, and then the ring beam and the reinforced concrete on the surface are poured.
7, the practice of frame structure, namely pouring column, beam, beam, plate, etc. Dismantle the formwork and then build the wall.
8. According to the requirements of quality supervision, the contractor may be required to provide the certificates of reinforcement (each batch), cement (each batch), mu 10 lime-sand brick (each batch) and cement concrete test certificate.
