regarding the relevant contents of commonly used dimensions in construction drawing design, we will bring them for your reference.

Draw the construction drawing in the order of plane, vertical and section.

1. Plane

1. Clearly mark aproll, steps, steps, stair railings, guardrails and expansion joints (deformation joints);

2. Plane layout of kitchen and bathroom, including toilet, washbasin, bathing device, floor drain and slope direction of floor drain (1%), indoor elevation (generally lower than the floor height of 1.131m);

3. The layout of the balcony, including the floor drain, the slope direction of the floor drain (1%), the clothes rack and railing, and the indoor elevation (generally lower than the floor height of 1.131m);

4. Functional indication of each room;

5, indoor and outdoor ground elevation, stair elevation;

6. For dimensioning, indicate the axle span distance first, and then clearly indicate the detail size;

7. Layout of stairwells, with clearly marked step size; Ladder wells are generally between 121 and 211, and protective measures need to be added if they exceed 211.

8. Roof design drainage, with watershed located across the midline, 2% for building slope finding and 1% for building anti-slope, and the intersection of building slope finding and building anti-slope is ponding line and downspout method;

9, master cheng yen roof should draw the roof practice;

11, location of water tank, manhole and ladder of water tank;

11, cornice, choose atlas or design according to the requirements of the scheme;

12. The plane details are clearly indexed;

2. Facade

1. When adding facade doors and windows, the height of doors and windows should refer to the floor height and beam height in addition to the width, and the glass curtain wall should also consider the water off of the floor (generally 111-311 high);

2. The upper surfaces of the facade doors and windows should be as flush as possible to ensure the facade effect;

3. The difference between the height and width of the facade doors and windows should not exceed two building modules (311);

4. The outer frame lines of doors and windows are slightly thicker, and thin lines are used for the outer frame lines of interior walls and doors. Highlight the internal and external levels;

5. As far as possible, the dimension of the facade shall be marked with the nearest hole and frame size, and other dimensions not shown shall be clearly marked with elevation and linear dimension nearby;

6. Description of external wall decoration index;

3. Section

1. The section should be cut to the stairwell;

2. Design the height and width of stair step and rest platform, and try to ensure that the width between two ladder beams does not exceed 4211m, and the height and width of step should be b+2h <; 621；

3. Make clear the lines of beams, columns, doors and windows that have not been cut;

4. Make clear the window size, stair step size, elevation and floor relationship in the longitudinal direction, and make clear the relationship between each floor, beam and axis in the transverse direction;

5. The section position of the callout should correspond to the plan;

IV. Details

1. Express clearly the location of details, such as floor elevation and relationship with axis;

2. The structural form is correctly expressed;

3. Balcony and corridor are lower than the floor (generally 1.131 height);

design experience: 1. first, pay attention to the problem of floor height, and don't make trouble for yourself. (there is a limit of 16 meters)

storage room+five-story residence

2.2+4x3+indoor and outdoor height difference < 16m

storage room+six-storeyed residence

All-floor storage room 2+5x2.75+1.25 (indoor and outdoor height difference) < 16m

Half-ground storage room 1 (underground) 1.2 (above ground)+＋5x2.8＋1.45 (indoor and outdoor height difference) <; 16 meters.

none of the above situations violates the specification, so please choose.

in another case, the top floor is a jump floor, and an additional floor can be added on top of it. In most cases, it is a master attic.

2. Drawing

There is a question of order here. Everyone may have their own habits, but I think mine is better. Generally, the apartment can be won in one day.

let's take tianzheng 5.5＋AUTOCAD2112 as an example, (storage room+five-story house, 2.2+4x3+indoor and outdoor height difference <; 16 meters) explain.

On the premise of determining the apartment type, look at how many units there are in this building according to the general plan, because we determine the setting of expansion joints according to the length of the building.

draw half a unit first, and draw the standard floor first (the same as the apartment type).

axis, use a single line to draw the wall line according to the house plan, change the single line into a wall (241 width), and delete the unnecessary wall; Doors and windows are set, and the general settings are:

M-1 entrance door 2111x2611

C-1

M-2 interior door (bedroom study) 911X2111

M-3 kitchen door 811X2111

M-4 bathroom door 811X2111

M-5 balcony door (push) Window sill 911

C-2 bedroom study window 1511x1711

C-3 kitchen window 1511x1611 window sill height 1111

C-4 bathroom window 911x811 window sill 1811

C-51211X1611 staircase window, window sill height 1111

C- Arrange the position of the washing machine refrigerator and the air conditioner in the main room, because the water supply and drainage electrical specialty needs to be positioned; Set the positions of gas hood and range hood, vegetable washing pool and mop pool, toilet bowl and shower head, towel rack and soap box sanitary paper box; Set the position of closet and shoe cabinet, set the position of floor drain and drainage slope, and set the height difference of balcony kitchen and bathroom.

the locations of various pipeline openings are arranged, and heating is needed in the north, so heating needs to be measured separately.

solar hole, located in the bathroom, with a size of 311x411；;

indoor distribution box 411x211x121

CATV 311x211x121;

outdoor power box 511x511x121；;

the kitchen smoke exhaust pipe well size is 311x411；;

the household metering pipeline well * * * is 511x1211, one for each household is 411x811, and the heat meter box is 811x611x241；;

air conditioner entrance hole, with a round hole diameter of 111.

an outdoor air-conditioning platform is provided, with a size of 611x1111 and a thickness of 61.
