Atlas
1. A collection of pictures, such as an atlas and a photo album, which are divided into categories and bound into volumes.
2. A collection of icons. Such as design drawings, a collection of normative samples and documentation prepared according to certain rules.
3. The atlas published by the state-designated technical and scientific research department is a technical document of regulatory nature that guides and regulates various professional entities and has identification and binding effects.
The horizontal method of construction drawings
The overall plan design method of structural construction drawings, referred to as the "flat method".
The flat method uses planes to express structural dimensions and elevations The drawing methods of , structure, reinforcement, etc. are used in structural construction drawings in buildings. There are special drawings and books for Pingfa, which must be studied.
In the past, structural construction drawings had section expressions, which meant sectionalizing each component in the structural drawing to reflect the cross-sectional size and steel bar size of the components in the form of sections. However, the information expression was repetitive and messy, which is basically the current situation. Not used on a large scale, just appears as a supplement in the structure diagram. Later, the beam table that appeared in Guangdong in the 1990s was a table specially set up for many beams. All the information about the beam components was filled in on it like filling in the blanks, and then the component structure diagram of the beam was set up on it, thus forming a beam table. , although it saves a lot of repeated information compared with the section, it is easy to make mistakes when filling in the beam table. The data is piled up, it is easy to fill in the wrong information, and it is not intuitive. The beam table should be checked against the structural floor plan. Unless it is used in a small area, Now it is basically eliminated.
Now in line with international standards, it is the flat method, which is a common language. The information of the components (sections, steel bars, spans, numbers, etc.) is directly marked next to the structural plan, and the whole is directly expressed in The structural floor plan of various components is combined with the standard structural details to form a new and complete structural design. It changes the traditional cumbersome method of extracting components from the structural floor plan and then drawing reinforcement details one by one.
