Detailed Description

As shown in fig. 1-4, the easily detachable stirrup of the present invention is used for binding a reinforcement cage, and is hooped outside a main reinforcement 4 of the reinforcement cage; the stirrup is formed by enclosing two U-shaped steel bars 1, and the two U-shaped steel bars 1 can be detachably connected. The stirrup is in a round corner rectangle, and the radius of the inner round corner is 2-6 times of the nominal diameter of the U-shaped steel bar 1, so that the stirrup can be tightly attached to the main bar 4 on the premise of not causing bending defects.

As shown in fig. 1 and 2, two U-shaped steel bars 1 can be selected to be connected in a butt joint mode, the connection mode is socket joint, and the connection position is in interference fit to maintain certain tensile strength. As shown in fig. 5, a socket 11 is provided on one end of each U-shaped reinforcement 1, and a socket 12 is provided on the other end, so that all the U-shaped reinforcements 1 can be of the same specification, and there is no need to specially find out different U-shaped reinforcements 1 with sockets 12 and sockets 11 when connecting. The spigot 12 of the U-shaped steel bar 1 is plated with copper to be tightly matched with the socket 11, and the length of the spigot 12 of the U-shaped steel bar 1 is not less than 5 times of the nominal diameter of the U-shaped steel bar 1, so that the sufficient tensile strength is ensured. The connecting mode is obviously convenient to install, the installation is completed by forcibly inserting the two ends of the U-shaped steel bars 1 after the ends are aligned, the shear strength of the connecting position is similar to that of the traditional stirrup, and the connecting structure can be used for buildings with low requirements on the earthquake resistance level.

As shown in fig. 3 and 4, the two U-shaped steel bars 1 can also be selected to be connected in a lap joint manner, and the joint is locked by a rivet 2, wherein the two U-shaped steel bars 1 are arranged along the length direction of the main bar 4 in a vertically staggered manner. The connection mode is convenient to install compared with socket connection, but the tensile strength of the connection position is higher, and the connector can be used for buildings with higher requirements on earthquake resistance grades. Of course, the two U-shaped reinforcing bars 1 may be staggered from side to side and lap-jointed, but then the U-shaped reinforcing bars 1 must be deformed so that the four corners of the stirrup contact the main reinforcement 4.

The stirrup can be fixed on main muscle 4 with staple bolt 32, and staple bolt 32 sets up in the stirrup four corners to with stirrup fixed connection, staple bolt 32 can be through tying 31 and stirrup ligature connection, also can with stirrup welded connection. Although the processing cost of the stirrup is high, the stirrup has high torsional strength, and is suitable for buildings with high requirements on the torsional strength.

The four corners of the stirrup can be pre-wound with the binding wires 31 to replace the anchor ears 32, and the binding wires 31 at the four corners can be directly fixed on the main reinforcement 4 after the stirrup is installed, so that the working hours of field installation can be saved.

In the embodiment, the easy-to-mount and easy-to-dismount stirrup comprises the following steps in the using process:

firstly, sleeving a main reinforcement 4 in two U-shaped steel bars 1 and connecting the two U-shaped steel bars 1 to form a stirrup;

fixing four corners of the stirrups on the main reinforcements 4;

and repeating the first step and the second step to finish the binding of the stirrups of the whole reinforcement cage.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
