∮8@ 100(2) is stirrup, with a diameter of 8 mm and a spacing of 100 mm, and (2) is double limb stirrup.
The front view of a building is an orthogonal view obtained by projecting different measurement surfaces of the building onto a vertical projection plane. The building profile is an orthographic drawing obtained by cutting the building with a vertical section according to the cutting position and projection direction indicated on the building plan. The building plan is a horizontal sectional view obtained by cutting horizontally above the window sill of the house, removing the upper part and using it for the orthographic projection of the rest. The construction drawing of a building project, referred to as "construction drawing" for short, is a drawing that shows the overall layout of the project, the external shape of the building, the internal layout, the structural structure, the internal and external decoration, the material method, the equipment and the construction requirements.
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.
1, a formal architectural design should be signed by the designer, the person in charge of the architectural drawings, the approver, the proofreader, and stamped with 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 combination of "building material description" and other drawings when reading drawings. In the "Description of Building Materials", each item is marked with "√", which is the practice adopted in the design. What is not ticked is not the design practice.
3. As shown in the architectural design: "c20 reinforced concrete jl(240400) with 4φ 16 wound φ 6 @ 200 stirrups." 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 length of the rectangular ring is about 340-350 mm, and the width is about 180 mm- 190 mm).
4. For example, in architectural design: "c20 concrete column (240240) with 4φ 12 hoop] 6 @ 200." Where "] 6 @ 200" is a nonstandard label and should be "φ 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" indicates the strength grade of cement mortar and "mu 10" indicates 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.
