Wire model for building reinforcement and steel bar

No. 20-22, then the length calculation is less than 12 rebar using 25 cm. 12-16 construction 30 cm, 18-25 use 35 cm of tied wire, one ton of steel construction 5 kg of tied wire.

Wrapping: In order to prevent the steel bar from sliding or falling off, it can be wound when tying, and the winding direction is determined according to the possible movement of the steel bar, and it can be wound once or twice. The wrap fastening can be combined with a cross flower.

buckle, reverse cross buckle, pocket buckle, etc.

Wrap fastening method: stirrups.

It should be perpendicular to the main reinforcement, the intersection of the stirrup corner and the main reinforcement should be tied, and the intersection point of the main reinforcement and the non-corner part of the stirrup is staggered with plum blossoms.

The tools used for rebar binding can be pliers.

Or iron hooks, using pliers can save some wire, but it is not as flexible and convenient as using hooks. There are many different shapes of iron hooks, either straight or oblique.

<> the wire tied for binding steel bars, there are two kinds of galvanized steel wire and fire wire. Generally, galvanized steel wire is used. However, in the case of a shortage of steel wire, thin iron wire can also be used, which becomes soft after fire, so it is also called fire wire.

The commonly used specifications for tying silk are 18 22 gauges. When the diameter of the binding steel bar is less than 12 mm, it is advisable to use No. 22 wire tie; At 12 25 mm, it is advisable to use No. 20 wire tie, and when it is more than 25 mm, it is advisable to use No. 18 wire tie. The length of the tie should not be too long or too short.

If it is long, it will cause waste, and if it is short, it will be inconvenient to operate. The length of the wire tie is generally in order to make the wire hook twist 2-3 times, and then leave about 10 mm.

One ton of steel bar construction 5 kg of tied wire.

The most suitable wire type for the reinforcement binding of steel bars with a diameter of 10 and a diameter of 20 in the reinforcement project is.

In the steel bar project, the diameter of 10, diameter 20 of the steel bar binding, the most suitable use of the wire type Bu hold the high number is pro! Hello, happy to answer your <>

In the reinforcing bar binding of diameter 10 and diameter 20 in the reinforcing bar project, the most suitable iron wire model is to use 20 iron wire to bind the steel bar with a diameter of more than 12, and 22 iron wire to bind the steel bar with a diameter of 10 or less. Before the reinforcement binding, carefully familiarize yourself with the drawings, check whether there are discrepancies between the batching list and the drawings and designs, carefully check whether the size of the finished product and the heart are consistent with the blanking table, and check that there is no error before binding. When the diameter of the stressed steel bar of the beam is equal to or greater than 22, it is advisable to adopt a welded joint, and when it is less than 22, a binding joint can be adopted, and the lap length should comply with the provisions of the specification.

The distance between the end of the lap length and the bend of the steel bar shall not be less than 10 times the diameter of the steel bar. The lashing joint should not be located at the maximum bending moment of the component, and the lap joint of the steel bar cover should be tied with iron wire in the center and at both ends. 1. The wire tied for binding steel bar generally refers to galvanized wire, also known as gold and silver wire, and the diameter and width of the commonly used wire are.

2. The common flat wire winding is 100 yard coil, 500 yard coil, and 1000 meter coil; Common flat wire slitting specifications are: 5cm, 6cm, 8cm, 10cm, 12cm, 16cm, 20cm, etc., generally 1000 bags, 100 boxes. The flat wire can also be made into a row of ties.

Small is 2 in a row, * can be 60 in a row. 3. The commonly used specification for silk tie is 18 22. When the diameter of the binding steel bar is less than 12 mm, it is advisable to use No. 22 wire tie; 12 When 25 mm, it is advisable to use 20 wire ties, and when it is more than 25 mm, it is advisable to use 18 wire ties.

How many threads should be used for each type of tie.

Rebar binding method.

Rebar binding is to tie the intersection of two rebar bars with tie wire. The method of lashing varies according to local customs. The most commonly used is the one-sided buckle operation.

The characteristics of this binding method are: easy operation, high work efficiency, strong versatility, the binding point is relatively reliable, and it is suitable for the binding of various parts of the reinforcement mesh and frame.

The steps of the one-side buckle operation method are to first bend the cut small strand of wire in the middle at 180 degrees, and it is advisable to hold it with the left hand. When binding, the right hand pulls out a wire tie, after bending the bend 90 degrees, the left hand passes the bent part through the bottom of the steel bar tie point, holds the wire hook and hooks the wire tie buckle, the index finger is pressed on the front of the hook, close to the open end of the wire tie, and rotates 23 times clockwise, that is, the binding of a node is completed. During operation, it is necessary to pay attention to the wire tie buckle extending through the bottom of the steel bar tie point not too long, and fasten it with the wire tie hook, so that not only the tie point is fastened, but also the binding speed is fast.

When one side of the buckle method is used to tie the steel mesh and frame, the thread buckle of each tie point.

It cannot be carried out in one direction and should be crossed. In this way, it is possible to make the binding of the reinforcement mesh,

The frame has good integrity and is not easy to deform.

In addition to the one-sided buckle method, there are also cross buckles, anti-cross buckles, pocket buckles, anti-cross buckles, pocket buckles, pocket buckles, etc. These methods can be selected according to local habits and the requirements of the lashing site.

There is no requirement for this acceptance in the specification. However, in the construction manual (fourth edition) 9 steel reinforcement engineering section of the steel bar installation, it is stipulated that the iron wire used for steel bar binding can be used 20 22 iron wire, of which 22 iron wire is only used for binding steel bars with a diameter of less than 12mm.

The length of the wire can be used with reference to the values in Table 9-80; Because the wire is made into a plate, it is customary to cut it off according to a fraction of the circumference of each wire.
