What does gzl mean in plane notation

planar annotation method"gzl"Indicates a straight pull bar. Steel structure tie strip is a steel structure building.

One of the components, its function is mainly used to regulate, control two adjacent purlins.

Stability, generally made of round steel with a diameter of 12, special purposes include the use of 14 and 16 round steel, with diagonal strips, straight strips.

The straight draw bar is generally made of 12 round steel, which is divided into two kinds, one is the diameter of the round steel, the two ends are turned into a thick diameter, and then the teeth are rubbed, and the other is made of the diameter of the round steel directly rubbed the teeth, and the surface treatment is selected according to the different uses.

There is hot-dip galvanizing. There are two types of electro-galvanized.

The general calculation method is as follows; Beam mid-span subscript:

KL-1 (3)4 200*600 - KL-1 is the beam number; (3) is a three-span; 200x600 is width x height.

is a smooth reinforcement with a diameter of 8 spacing 200

The spacing at the encryption is 100;

2 18, 2 16 - the bottom of the beam stressed reinforcement is 2 18, and the upper reinforcement is 2 16;

N4 12 - 4 waist bars in the middle of the beam, two on one side;

The upper left side is marked as: 2 20 + 1 18 - the left top rib is 2 20 + 1 18, referring to from.

To the middle third of the span, the upper reinforcement is 2 20 + 1 18;

The upper left of the middle span of the beam is marked as: 2 20+1 18 - same as above.

The upper left of the right span of the beam is marked as: 2 20 + 1 18 - same as above.

The upper right is marked as: 2 20 + 1 16 - the right top rib is 2 20 + 1 18, referring to the slave.

To the middle third of the span, the upper reinforcement is 2 20 + 1 18;

2 20+1 18 means yes.

place. When the beam is in the middle of the span, it is pulled down and pressed, and at the support, it is pulled up and down, so the reinforcement should be added here.

It is recommended that you take a look at the concrete construction manual (to be relatively new) which has the meaning of flat representation, the help file of PKPM, and the GB101 should also have it!

Represents two 20 steel bars, arranged throughout length, for double-limb hoops. 2 22 + (4 12) means that 2 22 is the length of the whole length, and 4 12 erection ribs are used for hexa-limb hoops. ⑶6φ25 4/2

It means that the upper reinforcement is 4 25 in the upper row and 2 25 in the lower row. 2 22+ 2 22 means that there is only one row of rebars, two at the corners and two in the middle, evenly arranged.

Fourth, the beam waist in the reinforcement representation method: g2 12

Represents the structural reinforcement on both sides of the beam, one 12 on each side. G4 14 represents the structural reinforcement on both sides of the beam, with two 14s on each side. N2 22 indicates the torsional reinforcement on both sides of the beam, one on each side 22. ⑷⑵

In the case, this annotation is the in-situ annotation, the column number is 1, from beginning to end, reinforcement, and there are more flat annotations in the reinforcement of the beam, and the plan view. If it is a cross-sectional drawing, specifically talking about a lot, 4, look at the 101 atlas, 2, the centralized annotation may have a line pointing to this beam between 1 and 2, at this time, the in-situ annotation shall prevail, indicating that the cross-section of the beam between 2 and 3 has changed, 3, which is generally the in-situ annotation of the steel bar change, illustrating the size of the beam (350 600), after 4 columns, the beam part, for example, a beam; But 250 600 is marked in the beam interval of 2 3

1. The main reinforcement on the beam and the main reinforcement under the beam are copied at the same time.

Attack method: 3 22, 3 20 indicates the upper steel.

The reinforcement is 3 22, and the lower reinforcement is 3 20. with a semicolon","3 22;3φ20。Represents the upper part 3 22 through length steel bar, the lower part of the steel bar 3 20 through length steel bar 2, beam upper part of the steel bar representation method:

marked at the support on the beam) 2 20 represents two 20 steel bars, through the long cloth.

The dimensions and reinforcement of structural components are directly represented on the structural layout plan of various components in accordance with the drawing rules of the overall representation method of the plane, and then combined with the standard structural details to form a new complete set of structural design representation methods.

It has changed the traditional cumbersome method of indexing the components from the structural plan design drawings and then drawing the template details and reinforcement details one by one.

I guess you can't read the structural drawings of flat annotation.

But it's impossible to explain them all to you, because there are too many atlases of flat laws.

The only way to do this is for you to look at the structure diagram with reference to the Atlas of Flat Laws.

If you need, I can send you an electronic version of the atlas.

If I don't understand correctly, please add a question.

The annotations on the building plan are divided into interior and exterior dimensioning, axis annotation. Room name and section and symbol callouts.

The axis number is pressed horizontally from left to right. , press a, b, c vertically from bottom to top. The order of the ;

There are 3 external dimensions, the inside is the detailed size, the specific size of each wall section and the distance from the positioning axis, the middle one is the axis size, and the outer one is the total length, total width, and total outer size of the building.

The internal dimensions reflect the dimensions that cannot be reflected from the outside, and are marked nearby.
