Applicable requirements, advantages and disadvantages of three connection methods of steel bars

Advantages:

1, simple structure;

2, high efficiency;

3, don't damage the steel bar.

Disadvantages: too much waste of steel bars; Bones deform easily.

Second, the welding method:

superiority

1, the steel skeleton is firm and not deformed;

2. Save steel bars.

Disadvantages:

1, steel bar is damaged;

2. Energy consumption.

Third, the threaded connection method:

superiority

1, without damaging the steel bar;

2. High degree of specialization (standard); It's also very simple.

Disadvantages:

1, the process is troublesome;

2, the installation is inconvenient;

3. Energy consumption.

Extended data:

Steel binding shall meet the following requirements:

1, steel intersection must be fastened with iron wire;

2, plate and wall steel mesh, the other must be in the middle of the intersection can be staggered fastened, but to ensure that the steel bar does not shift. Two-way reinforced fabric, all must be fastened;

3, beam and column reinforcement, in addition to the design requirements, stirrups should be set vertically on the reinforced bar.

4. When the slab and secondary beam intersect with the main beam, the slab reinforcement is in the middle and the secondary beam reinforcement is next; When there is a ring beam or cushion beam, the reinforcement of the main beam is on the floor.
