How to mark the vertical bar in the middle frame of Glodon, such as 2B16 2B16

Set up the erection bars.

There are two ways, one is to enter the middle span reinforcement (2b16) in the in-situ annotation, and the erection reinforcement information needs to be enclosed in parentheses, and the other is to enter 2b16+(2b16) in the upper reinforcement of the centralized annotation, which also needs to be bracketed.

In this design drawing, there are erection reinforcements and negative reinforcements marked in the design drawings or descriptions.

The form of the long rib of the middle and upper longitudinal reinforcement is marked in a centralized manner, e.g., 2 d1. However, when the stirrups of the beam are "limb hoops", the upper reinforcement of the centralized annotation can not all be marked in the form of a long reinforcement, and the "erection reinforcement" must also be labeled, and the upper longitudinal reinforcement of this time should be labeled"s1фd1+(s2фd2)"In this form, the reinforcement inside the parentheses is the erection bar.

Generally speaking, the erection bar is used to erect stirrups in the beam, almost appear in the beam above the three limb stirrups, that is, the ribs on both sides are passed, and the middle ribs are only additional ribs (that is, we say pick ribs), if there is no erection bar, the limb stirrups in the middle can not be tied, so there is a erection bar. It can also be said that the corner bars that are not stressed are erection bars.

The current "Code for Design of Concrete Structures" GB50010-2010 stipulates that the diameter of the erection reinforcement in the beam should not be less than 8mm when the span of the beam is less than 4m; When the span of the beam is 4-6m, it should not be less than 10mm; When the span of the beam is greater than 6m, it should not be less than 12mm. When the upper part of the beam has both long ribs and erection ribs, the lap length is 150mm.

In the shear wall structure and the frame-shear wall structure, the beam that connects the wall limb with the wall limb and the wall limb with the frame column is called the connecting beam.

The side frame beam is the beam on the side axis frame.

In the case that there is no long rib through bai, du is directly entered in the centralized annotation (zhi frame vertical rib), and dao remembers to add parentheses. version as for the original.

Weight annotation, direct input parameters are automatically processed.

2] erection reinforcement: erection reinforcement refers to the erection of the steel bar in the beam, in order to make the longitudinal reinforcement and stirrups can be tied into a skeleton, the four corners of the stirrups must be configured along the length of the whole beam longitudinal reinforcement, in the section without longitudinal stress reinforcement, then the erection reinforcement should be supplemented. The main function of the erection bar is that when the number of roots of the longitudinal reinforcement at the upper part of the beam is less than the number of corners of the upper stirrup, the corner of the stirrup is provided with support, so the erection bar is the longitudinal structural reinforcement that erects the stirrup.

If there are special circumstances in the construction process, refer to the general description of the drawings.

"There is also a label of gluten 4b20 2b16 here in the span beam" This is an in-situ call, which means that the beam reinforcement in this span should be 4b20 2b16 (the span is long).

One is centralized annotation and the other is in-situ annotation, and in-situ annotation is the part of the annotation that is different from centralized annotation.

G4B12 is a structural reinforcement, torsional resistance, 4 on each side of the beam on both sides of the suit.

One is centralized annotation, one is in-situ annotation, JKL3 (4) represents the foundation frame beam 3, four spans, b * H = 250 * 700, stirrups 8 spacing 100-200, two limb hoops ,,,g represents the structure of the waist bar (different from the anchorage length of the torsional waist bar, that is, the force mode is different), and accompanied by the hook, the spacing of the hook is twice the stirrup spacing, plum blossom layout,

1. Enter the software drawing input dark column definition module, create a new parametric dark column (select the corresponding shape), and name it GBZ1.

2. Select "Yes" for the cross-section, enter the modification interface, the cross-sectional size, and select the reinforcement by box, and delete all of them.

3. Cloth corner ribs (1C20), the software automatically arranges 8, 4 longitudinal bars need to be modified, click to modify the longitudinal bars, box select the 4 required longitudinal bars, and modify them to 4C12.

4. Arrange the side bars (1C12), or click a few times on the edge you want to arrange to be a few steel bars.

5. Arrange stirrups (A6-150).

6. Modify stirrups.

Finish building the component.

In the custom section dark column, draw your own stirrups You can modify the stirrup diameter at will.

1. After the main reinforcement is automatically generated, all the unnecessary reinforcements are deleted.

2. Select the 4 steel bars in the top row and set it to 4C16. Then select all 16 of the following roots, and set it to 16c20 (not necessarily 16 roots, there are a few count).

3. Click "Cloth Edge Bar", click the dotted line at the top 300 side length position, set 1C16, and the rest are the same as the position. The lower segment of the 750 side length below is set to 1c16, and the rest is the same position.

4. Then draw stirrups according to the sample drawing, and I won't say anything if you don't ask.

Click on the dotted lines on each side.
