What does it mean to encrypt spacing inside the building structure

The spacing of the same kind of steel bar in the building structure is not set in stone when it is arranged. For example, the beam and column structure is stressed more in the connection point area, so the spacing of the stirrups in the beam and column structure in this area will be relatively dense, and there is no need to encrypt the spacing of the stirrups in other areas with less force, so in order to save materials (in order to save money), the spacing of the stirrups will be increased a little. Generally, the encryption spacing is annotated on the reinforcement diagram.

For example: 12 10@120 200 means 12 sticks with a diameter of 10mm, an encryption pitch of 120mm, and a non-encryption pitch of 200mm. Hope it will help you.

According to different seismic ratings.

The range of the infill area of the beam and column has a definite value.

Beam. Level 1 2 times the beam height and the greater value of 500 The second, third and fourth levels are the greater value of the double beam height and 500.

When the seismic design is carried out, the stirrup is inflated.

shall meet the following requirements:

1. The upper end of the bottom column and the two ends of the columns of other layers should be taken as the maximum value range of the long side of the rectangular section column (or the diameter of the circular section column), the net height of the column 1 6 and 500mm;

2. The range of 500mm above and below the rigid ground of the bottom column;

3 The range of the net height of 1 3 columns above the root of the bottom column;

4 Shear-span ratio.

no more than 2 columns and infill walls.

The ratio of the net height of the column to the cross-sectional height of the formation is not greater than the full height range of the column;

5 The full height range of the corner posts of the first and second class frames;

6 The full height range of the column that needs to be increased in deformability.

For example, 6@200 300(2) means that the diameter of the steel bar is 6The distance between the two ends of the encryption interval is 200mmThe distance between the middle non-encrypted interval is 300mm, and it is a double hoop. The length of the encryption segment is calculated.

It's about rebar, right? Know that the crypto zone Hefei crypto zone is not! The meaning is the distance between the two steel bars, and the encryption spacing is the distance between the two adjacent steel bars in the encryption area.

Generally, it refers to stirrup encryption, that is, the spacing of the encryption area is smaller, which is called encryption, and the spacing of the encryption area is the distance between the stirrups. Hope it helps.

Are you talking about just going inside? Or other, there is a general spacing in it, and the encryption spacing is smaller than that.

The beam height is the encrypted spacing range of the reinforcement stirrups of the beam!

Generally, the stirrups at the end of the beam, the end of the column, and other positions need to be encrypted, see Atlas 101 for details.

The general reinforcement encryption is smaller than the spacing required for normal calculations. For example, column encryption is the normal calculation of the last stirrup.

The spacing to the next stirrup is 200mm, and the shear shear stirrup spacing of the support part is changed to 100mm, which is called encryption, and the encryption spacing is 100mm.

The first floor of the infill area of the column is 1 3 of the column net height, and the upper and lower infill areas of the floor are 1 6 or more than 500 of the column net height; The beam infill area is the area where the beam height is twice as high as the beam support or greater than 500.

Is it the stirrups of the rebar, and the stirrups of the rebar have an infill area.

This is because of the reasons why the shear span is worse than the short column in the measures that should be taken.

Core column (English name: corecolumn) is a reinforced concrete column inside the masonry formed after inserting vertical steel bars into the internal cavity of the block and pouring concrete. The core column is an internal reinforcement area formed by the addition of longitudinal reinforcement and stirrups in about one-third of the core part of the frame column section.

Under the action of periodic repeated horizontal loads, this kind of column has good ductility and energy dissipation capacity, which can effectively improve the seismic performance of reinforced concrete columns under the condition of high axial compression ratio. In order to facilitate the passage of beam reinforcement, the side length of the core column should not be less than 1 3 of the column edge length or diameter, and should not be less than 250mm.

4 frame beams; three-span; a represents a cantilevered at one end;

The bottom of the beam section is high;

%13210”？？Stirrup spacing encrypt area.

Version 100, non-encrypted zone 200, limb hoops;

4 upper iron (erection ribs) with a diameter of a certain number; 10 lower iron (main reinforcement) with a diameter of a certain number, 5 5 double row arrangement, 5 upper and lower 5.

G structural reinforcement is the same as above.

132 is a steel bar, what level is it? For example, 20 is a primary bar with a diameter of 20.

I graduated this year, and I didn't understand it at first. It is recommended to take a look at the 03-101-1 atlas, the flat representation of beams, plates and columns.

KL4 (3A) refers to the frame beam No. 4, a total of three spans, the beam section is 400 times 800, the following you must have written wrong, the first refers to the stirrups, limb hoops, the spacing of the encryption area is 100, and then the following is to say the main reinforcement, but %%132 I have not seen it either.

In the architectural drawings, the diameter of 8@100 200 (2) refers to the diameter of the stirrups 8mm, and the spacing in the infill area is 100mm; The spacing in the non-encrypted area is 200mm. It's all limb hoops. According to the rules of flat drawing "11G101-1" cartographic rules:

1. The level, diameter, spacing and number of limbs of the stirrups should be annotated when the stirrups of the beam and column are annotated. where the spacing of the stirrups is indicated by "@". When the stirrup spacing between the encrypted and non-encrypted areas is different, separate them with a slash " ".

Finally, the number of limbs of the stirrups is denoted by "(x)". When x is 2, it means a double limb hoop, and when x is 4, it means a limb hoop.

2. The stirrups of each span of the continuous beam should be marked in situ in each span when they are different.

8 means: the diameter of 8mm steel bar, @表示: spacing, 600 * 600 that is: 8@600x600 means: the diameter of the main reinforcement and distribution reinforcement are 8 mm, and the spacing is 600mm. Other stirrup representations:

10@100 200 (2) means: stirrups are 10, the spacing of the encryption area is 100, the spacing of the non-encryption area is 200, and all are double limb hoops.

10@100 200 (4) means: stirrups are 10, the spacing of the encrypted area is 100, the spacing of the non-encrypted area is 200, and all are limb hoops.

A steel mesh with a vertical and horizontal spacing of 600 is made of round steel with a diameter of 8 mm.

The thread diameter is 8, and the stirrup specification is 600*600

The spacing of the reinforcing bars of 8 threads is 600mm, and the stirrup specification is 600*600

@在建筑中是间距的意思, it is generally used when representing the stirrups of the beam, such as: 100 is to indicate that the spacing of the stirrups of the beam is 100mm, 100 200 is to indicate that the stirrup spacing of the infill area of the beam is 100mm, and the stirrup spacing of the non-infill area is 200mm.

Isn't it something like 8@200?

It means 8 reinforcements, with a spacing of 200 lashing.

Represents spacing in structural drawings.

In the reinforcement diagram, it is generally the spacing (@200就代表间距为200毫米) of the reinforcement arrangement
