2, the enclosure of the thermal insulation practices and parameter design. According to the results of energy-saving calculations, with reference to national and local energy-saving design specifications, the building roof, exterior walls, bottom contact with the outdoor air of the elevated or picket floor, non-heating and air-conditioning rooms and heating and air-conditioning rooms between the partition wall and floor, heating and air-conditioning basement walls, ground (perimeter and non-perimeter ground) and other parts of the thermal insulation structure design, control of its heat transfer coefficient; the building windows (including transparent), roof transparent part of the thermal insulation structure. Curtain wall), the roof of the transparent part of the frame material and glass species design, control its heat transfer coefficient and visible light transmission ratio, as well as wind pressure, airtightness and other physical properties.

If some parameters exceed the specification limits, but also to choose the reference building to weigh the judgment.

3, detail node structure design. The building's exterior windows, daughter walls, rainwater outlets, deformation joints, smoke or ventilation shafts and outdoor air contact shafts, shafts out of the roof, exterior door and window frames and gaps between door openings, floating windows, pick-up air conditioning panels and other detail nodes for structural design, usually can be selected from the standard drawing set of practices.

Sixth, the general plan. General architectural plan is to show that the new house is the basis of the overall arrangement of the relevant scope, he reflects the new, proposed, original and demolition of houses, structures, etc., location and orientation, outdoor sites, roads, landscaping and other arrangements, topography, landforms, elevation, etc., as well as the relationship between the original environment and the neighboring situation. The general building plan is also the basis for the positioning of the construction of houses and other facilities, earthwork construction, and the drawing of water, heating, electricity and other pipeline master plan and the construction of the general plan.

Seventh, plan, elevation, section and detail. This is the main body of the construction drawings, is the main display of the design results.

1, the building plan is referred to as the floor plan, is more important in the construction of the building of the basic diagram. Floor plan is a horizontal section of the building levels, assuming that the horizontal section through the door and window openings of a house (remove the upper part of the house), the section below the downward projection, the resulting horizontal section, known as the floor plan. The building plan both represents the building in the horizontal direction of the combination of the relationship between the various parts of the building, but also reflect the relationship between the building space and the vertical components that enclose them.

2, elevation drawings. According to the principle of projection, the elevation should be all visible details on the elevation are expressed. However, due to the small scale of the elevation drawings, such as doors and windows fan, cornice structure, balcony railing and wall complexity of the decoration and other details, often only with the legend. Their construction and practice, have another detailed drawings or text description. Therefore, it is customary to draw only one or two of these details as a representative, the other can be simplified, only need to draw their outlines. If the house is symmetrical left and right, the front elevation and the back elevation can also draw half, separate layout or merge into a map. When combined, should draw a straight symmetry symbol in the middle of the drawing as a demarcation line.

3, section. Sectional drawings, also known as cutaway drawings, is through the relevant graphics in accordance with certain cutaway direction of the internal structure of the display of the legend, sectional drawings is the assumption that a cutaway plane will be an object cut open, remove between the observer and the cutaway plane, for the remaining part of the projection plane to the projected surface of the projection map, to supplement and improve the design documents, is the detailed design of the engineering design for the construction of the construction work to guide the engineering operations.

4, detail drawing. Detailed drawing symbols and detailed drawing index symbols: in order to facilitate the map, often using detailed drawing symbols and detailed drawing index symbols. Detailed drawings of the sign, also known as the detail symbols, drawn in the bottom of the detail; detail index sign, also known as the index symbols, said the building level, elevation, section of a part of the plan to be drawn in another detail, so the detail index symbols are marked in the need to draw a detail of the location of the vicinity, and lead with a lead line out. Standard drawing in the detail symbol with a thick straight line drawn in a circle, 14 mm in diameter, such as detailing and indexed drawings in a drawing, directly with Arabic numerals indicate the detail number, such as not in a drawing, with a thin straight line in a circle drawn in a horizontal straight line, the upper half-circle indicates that the detail number, the lower half-circle indicates that the indexed drawings of the paper number.
