Technological formula of reinforcement

Working formula of reinforcement: remember that reinforcement should be bound, and staggered joints should not be pasted. Determine the elevation and find the horizontal axis, and all nodes should shrink. Confirm the number of corner reinforcement and the intersection position is concentric and in the same direction. The top beam of the building must be supported, and the beam support cannot be wrong.

1, steel binding to remember, staggered joints can't stick.

Attention should be paid to the cross-binding between reinforcing bars to ensure that the binding structure is firm and there will be no dislocation and falling of reinforcing bars. The joints of steel bars are staggered and cannot be glued together. At the same time, overlapping or winding errors should be avoided to ensure that the steel bars can be fully connected and exert their strength.

2. Determine the elevation and find the horizontal axis. All nodes should shrink.

Determine the elevation and find the horizontal axis: before reinforcement construction, determine the reference elevation according to the design drawings and construction requirements, and find the corresponding horizontal axis and vertical axis; Contraction joints should be reserved for all joints: in the process of reinforcement arrangement and construction, certain contraction joints should be reserved to cope with various changes in construction, so as to ensure the overall stability and safety of the building structure.

3. Confirm the number of corner bars, and the intersection position is concentric and in the same direction.

Confirm the amount of corner reinforcement: when arranging corner reinforcement, it is necessary to confirm the corresponding amount of reinforcement according to the design requirements to ensure that the reinforcement can fully play its role at the corner; Intersection position is concentric in the same direction: at the intersection or connection position of steel bars, it is necessary to ensure that the direction and position of steel bars are concentric with each other, and this principle should be followed when arranging and connecting steel bars.

4. The top beam of the building must be supported, and the bearing capacity of the girder cannot be wrong.

The beam and column at the top of the building must be supported: when arranging the steel bars at the top of the building, special attention should be paid to the support of the beam and column to ensure the bearing capacity and stability of the beam and column. Girder support must not go wrong: when connecting and supporting girders, the accurate position and positioning of connection points and supports must be ensured, and dislocation or deviation is not allowed.

The work content of the steel bar worker:

1 steel bar pretreatment

Pre-cutting, pre-welding, pre-bending and other pre-treatments are carried out on the purchased steel bars to ensure that the steel bars meet the design and construction requirements. Reinforcement pretreatment can improve the use value and economic benefits of reinforcement, better serve the construction and ensure the stability and safety of the building structure.

2, steel bar layout

According to the design requirements, the reinforcement shall be arranged and connected according to the requirements of the construction drawings, and the reinforcement shall be installed firmly to ensure the firmness of the structure.

3, steel cutting and drilling

According to the construction requirements, the steel bar is cut and drilled according to the required length by using tools such as electric scissors, flat mill and drilling machine.

Step 4 weld

Weld the steel bars that need to be connected to ensure that the joints meet the required strength and firmness. Welding is an important technical link in steel bar work, which is mainly used to connect different specifications of steel bars to ensure the stability and strength of steel bars.

5. Filling concrete

Before pouring concrete, reinforce the steel bars with iron mesh or steel bars, and mix them together after pouring concrete.

6, detection and adjustment

Check and adjust the installed steel bars, correct mistakes, ensure the accuracy and accuracy of steel bars, and make the structure meet the design standards.
