Code for Installation of Reinforcement in the 4th Edition of Building Construction Manual

The main purpose of steel binding construction is to effectively fix the formed steel bars in the corresponding parts according to the requirements of design drawings to form the design shape. In the process of construction, the following points should be noted:

Accurate binding position

The location of binding and reinforcement (reinforcement type, molding size and reinforcement location) is accurate and firm, so that it will not be deformed due to vibration during concrete pouring;

Comply with the specifications and design requirements.

Binding joint, joint position, joint distribution rate, reinforcement spacing, anchorage length, etc. Comply with the specifications and design requirements.

Placement of protective layer cushion block

When binding steel bars, the protective layer pad must be placed according to the designed protective layer thickness, and bound firmly with steel bars, and shall not be displaced.

Eight-character buckle method

When binding steel bars, the method of "eight-character buckle" is generally adopted to ensure that steel bars are bound in place, and long iron wires should be thrown inside to prevent people from sticking or being exposed after pouring concrete;

Plum blossom binding method

When the flat plate is bound, the plum blossom binding method can be used for one-way plate, but there shall be no less than two fixed bindings around the edge of the plate, and both two-way plates shall be fixed.
