Chapter 1 General Provisions



Article 1.0.1 This drawing rule is formulated with a view to standardizing the application ofIch-CD for building structure construction drawing, guaranteeing unified structure construction drawing drawn based on Ich-CD and ensuring the quality of design and construction.

Article 1.0.2 The drawing rules of this drawing collection are applicable to construction drawing design for concrete independent foundation, strip foundation, pile foundation bearing platform as well as foundation connecting beam and underground frame beam.

Article 1.0.3 Where adopting the drawing rules, it shall not only comply with this drawing collection, but also the current relevant standards, codes and specifications of the nation.

Article 1.0.4 Foundation structure construction drawing drawn based on Ich-CD shall directly express plan position, dimension and reinforcement of various foundation members in foundation layout plan according to Ich-CD drawing rules of various foundation members. For complex industrial and civil buildings, plan or necessary details for formwork, foundation pit, reserved hole, embedded parts, etc. shall be added if necessary.

Article 1.0.5 Express dimension and reinforcement of independent foundation, strip foundation, pile foundation bearing platform, foundation connecting beam and underground frame beam in layout plan, adopting the notations for plane and supplemented by notations for section.

Article 1.0.6 Construction drawings, drawn based on Ich-CD, of independent foundation, strip foundation, pile foundation bearing platform, foundation connecting beam and underground frame beam shall number all the foundation members according to the drawing rules of this drawing collection; the number contains type code and its main function is to designate the selected standard construction details; code has been noted in the standard construction details according to member type so as to define complementary relation of same members in details and Ich-CD, and thereby combining the two to constitute complete foundation construction drawing design.

Article 1.0.7 Construction drawings, drawn based on Ich-CD, of independent foundation, strip foundation and pile foundation bearing platform shall adopt table or other mode to note the datum elevation and ±0.000 absolute elevation of foundation bottom.

This drawing collection shall be used in conjunction with national building standard design 03G101-1 and 04G101-3; in the identical single project, the determination for floor (ground) elevation of structural layers, height of structural layers and datum elevation of foundation bottom must be unified, so as to guarantee such members as subgrade and foundation, column and wall, beam, slab and stair are marked according to unified vertical orientation relation. For the convenience of construction, the unified floor (ground) elevation of structural layers, height of structural layers and datum elevation of foundation bottom shall be respectively noted in Ich-CD of various members such as foundation, column, wall and beam.

Notes: 1. The bottom elevation of independent foundation and strip foundation is the top elevation of foundation bed (including waterproof layer) covering subgrade; the bottom elevation of pile foundation bearing platform is the top elevation of cushion layer (including waterproof layer) covering upper surface of soil between piles.

2. Where the bottom elevation of all foundations in specific engineering is same, the datum elevation of foundation bottom is the foundation bottom elevation; where the foundation bottom elevation is different, the majority of same bottom elevation shall be taken as the datum elevation of foundation bottom; for other minority of different elevations, the relative positive-negative dimension with datum elevation shall be noted according to specific rules.

3. Floor (ground) elevation of structural layers refers to the elevation value of floor (ground) elevation of each layer deducting practice thickness of building surface layer and cushion layer in architectural drawing. For the convenience of construction, the number of structural layers shall be corresponding and consistent with that of building storeys; under special circumstances, the structural layers without corresponding building storey number may be added. E.g. when underground frame beam which is buried in soil is arranged through general method, it may be regarded as one structural layer, and then the top elevation of underground frame beam is the floor (ground) elevation of structural layer.

Article 1.0.8 To faciliate the design expression and construction drawing recognition, the coordinate directions of structural plane are specified as follows:

1. Where two-direction axis grids are in orthogonal layout, the drawing shall be X direction from left to right and Y direction from down to up; where axis grid rotates in some position, the rotation angle of local coordinate direction along the axis grid shall make corresponding rotation, and the coordinates after rotation shall be diagramed.

2. Where the axis grid is arranged centripetally, the tangential direction shall be X direction and the radial direction shall be Y direction, and they shall be diagramed.

3. For the area with relatively complex plane layout, such as turning and bordering area of axis grid and core zone with centripetal arrangement, the plane coordinate direction shall be specified separately by the designer and diagramed.

Article 1.0.9 In order to ensure the construction personnel execute exacctly in accordance with Ich-CD, the general specification for the structure design in specific engineering must add the following contents closely related to Ich-CD:

1. The drawing collection No. (e.g. this drawing collection No. is 06G101-6) of the selected standard Ich-CD shall be noted in order to avoid adopting wrong edition during construction after the drawing collection is updated.

2. Concrete strength grade and steel bar grade of independent foundation, strip foundation and pile foundation bearing platform adopting Ich-CD shall be noted in order to determine the minimum anchorage length and the minimum overlapping length, etc. of the relevant tensile steel bar.

3. Where post-pouring strip is arranged, position and pouring time of post-pouring strip as well as specific requirements for strength grade, mix proportion, etc. of post-poured concrete shall be noted.

4. Environment category of members shall be noted; e.g. the condition that the environment category is "II-a" or "II-b" and there are specific requirements for concrete cover thickness of foundation members shall be described.

5. Specific changed contents shall be noted where partial change needs to be made for the standard construction details of this drawing collection in specific engineering.

6. Where the specific engineering adopting Ich-CD has special construction uncovered in this drawing collection, it shall be supplemented in the construction drawing.

Article 1.0.10 The concrete cover thickness and the overlapping and anchorage length of stressed steel bars shall comply with the relevant construction requirements in standard construction details of this drawing collection, unless otherwise noted in the structure construction drawing.

第1章 总 则
第1.0.1 条为了规范使用建筑结构施工图平面整体设计方法，保证按平法设计绘制的结构施上图全国统一，确保设计、施工质量，特制定本制图规则。
第1.0.2条 本图集制图规则适用于混凝土独立基础、条形基础、桩基承台，以及基础连梁和地下框架梁的施工图设计。
第1.0.3条 当采用本制图规则时，除遵守本图集的规定外，还应符合国家现行有关标准、规范和规程的规定。
第1.0.4条 按平法设计绘制的基础结构施工图，应根据具体工程设计，按照各类基础构件的平法制图规则，在基础平面布置图上直接表示各类基础构件的平面位置、尺寸和配
筋。对于复杂的工业与民用建筑，当需要时应增加模板、基坑、留洞和预埋件等平面图或必要的详图。
第1.0.5条 在平面布置图上表示独立基础、条形基础、桩基承台，以及基础连梁和地下框架梁的尺寸和配筋，以平面注写方式为主，以截面注写方式为辅。
第1.0.6条 按平法设计绘制的独立基础、条形基础、桩基承台，以及基础连梁和地下框架梁施工图，应将所有的基础构件按本图集制图规则进行编号，编号中含有类型代号，其主要作用是指明所选用的标准构造详图；在标准构造详图上，已按其所属构件类型注明了代号，以明确该详图与平法施工图中相同构件的互补关系，使两者结合构成完整的基础施工图设计。
第1.0.7条 按平法设计绘制的独立基础、条形基础、桩基承台施工图，应采用表格或其他方式注明基础底面基准标高，以及±0.000的绝对标高。
本图集应与国家建筑标准设计03G101-1及04G101-3配合使用；在同一单项工程中，其结构层楼(地)面标高与结构层高和基础底面基准标高的确定必须统一，以保证地基与基
础、柱与墙、梁、板、楼梯等构件按照统一的竖向定位关系进行标注。为施工方便，应将统一的结构层楼(地)面标高与结构层高和基础底面基准标高分别注写在基础、柱、墙、梁等各
类构件的平法施工图中。
注：1.独立基础、条形基础底面标高为覆盖地基的基础垫层(包括防水层)的顶面标高；桩基承台底面标高为覆盖桩间土上表面的垫层(包括防水层)的顶面标高。
2.当具体工程的全部基础底面标高相同时，基础底面基准标高即为基础底面标高；当基础底面标高不同时，应取多数相同的底面标高为基础底面基准标高；对其他少数不同标高者，应按具体规则注明其与基准标高的相对正负尺寸。
3.结构层楼(地)面标高系指将建筑图中的各层楼(地)面标高扣除建筑面层及垫层做法厚度后的标高值。为方便施工，结构层号应与建筑楼层号对应一致，在特殊情况下，可以增加无对应建筑楼层号的结构层。例如，当普遍设置埋在土中的地下框架梁时，可将其作为一个结构层，地下框架粱的顶部标高即为该结构层楼(地)面标高。
第1.0.8条 为方便设计表达和施工识图，规定结构平面的坐标方向为：
1.当两向轴网正交布置时，图面从左至右为X向，从下至上为Y向；当轴网在某位置转向时，局部坐标方向顺轴网的转向角度做相应转动，转动后的坐标应加图示。
2.当轴网向心布置时，切向为X向，径向为Y向，并应加图示。
3.对于平面布置比较复杂的区域，如轴网转折交界区域、向心布置的核心区域等，其平面坐标方向应由设计者另行规定并加图示。

坡形 BJP xx
设计时应注意：当为独立基础截面形状为坡形时，其坡面应采用能保证混凝土浇筑、振捣密实的较缓坡度；当采用较陡坡度时，应要求施工采用在基础顶部坡面加模板等措施，以确保独立基础的坡面浇筑成型、振捣密实。
第3节 独立基础的平面注写方式
第2.3.1条 独立基础的平面注写方式，分为集中标注和原位标注两部分内容。
第2.3.2条 普通独立基础和杯口独立基础的集中标注，系在基础平面图上集中引注：基础编号、截面竖向尺寸、配筋三项必注内容，以及当基础底面标高与基础底面基准标高
不同时的相对标高高差和必要的文字注解两项选注内容。
素混凝土普通独立基础的集中标注，除无基础配筋内容外，其形式、内容与钢筋混凝土普通独立基础相同。
独立基础集中标注的具体内容，规定如下：
1.注写独立基础编号(必注内容)，见表2.2.1。
独立基础底板的截面形状通常有两种：
(1)阶形截面编号加下标“J”，如DJJxx、BJJxx；
(2)坡形截面编号加下标“P”，如DJPxx、BJPxx。
2.注写独立基础截面竖向尺寸(必注内容)。下面按普通独立基础和杯口独立基础分别进行说明。
(1)普通独立基础：
注写h1/h2/……，具体标注为：
1)当基础为阶形截面时，见示意图2.3.2-1；

图2.3.2-1 阶形截面普通独立基础竖向尺寸
例：当阶形截面普通独立基础DJJxx的竖向尺寸注写为300/300/400时，表示h1=300、h2=300、h3=400，基础底板总厚度为1000。
上例及图2.3.2-1为三阶；当为更多阶时，各阶尺寸自下而上用“/”分隔顺写。
当基础为单阶时，其竖向尺寸仅为一个，且为基础总厚度，见示意图2.3.2-2。

图2.3.2-2 单阶普通独立基础竖向尺寸
2)当基础为坡形截面时，注写为h1/h2，见示意图2.3.2-3；

图2.3.2-3 坡形截面普通独立基础竖向尺寸
例：当坡形截面普通独立基础DJPxx的竖向尺寸注写为350/300时，表示h1=350、h2=300，基础底板总厚度为650。
设计时应注意：当普通独立基础底板以上为现浇钢筋混凝土柱墩时，应结合柱墩构件设计进行表达，详见国家建筑标准设计04G101-3相关章节。
(2)杯口独立基础：
1)当基础为阶形截面时，其竖向尺寸分两组，一组表达杯口内，另一组表达杯口外，两组尺寸以“，”号分隔，注写为：a0/a1，h1/h2/……，其含义见示意图2.3.2-4、图2.3.2-5、图2.3.2-6和图2.3.2-7，其中杯口深度a0为柱插入杯口的尺寸加50mm。

3.注写独立基础配筋(必注内容)。
(1)注写独立基础底板配筋。
普通独立基础和杯口独立基础的底部双向配筋注写规定如下：
1)以B代表各种独立基础底板的底部配筋。
2)X向配筋以X打头、Y向配筋以Y打头注写；当两向配筋相同时，则以X&Y打头注写。当圆形独立基础采用双向正交配筋时，以X&Y打头注写；当采用放射状配筋时以Rs打头，先注写径向受力钢筋(间距以径向排列钢筋的最外端度量)，并在“/”后注写环向配筋。
3)当矩形独立基础底板底部的短向钢筋采用两种配筋值时，先注写较大配筋，在“/”后再注写较小配筋。
注：当柱下为单阶形或为坡形截面，且其平面为矩形独立基础时，根据内力分布情况，设计者可考虑将短向配筋采用两种配筋值，其中较大配筋设置在长边中部，分布范围等于基础短向尺寸；较小配筋设置在基础长边两端，各端分布范围均为基础长边与短边长度差的1/2。参见本图集的标准构造详图。
例：当(矩形)独立基础底板配筋标注为：
