Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
The invention discloses a multifunctional stirrup for controlling the thickness of a steel bar protection layer and a floor slab.
Referring now to fig. 1, fig. 1 is a schematic diagram of a stirrup according to an embodiment of the present invention. As shown in the figure, the two J-shaped rods are inverted and are reinforcing steel bar supports with the same shape and size, each J-shaped rod is provided with a bottom rod 1, the length of each bottom rod is 150-200mm, the middle part of each bottom rod is connected with the bottom end of an upright rod 2, the bottom rods and the upright rods are vertically fixed, the height of each upright rod is set according to the thickness of a floor minus the thickness of a protective layer of the floor and the diameter of a reinforcing steel bar of each bottom rod, the top end of each upright rod is provided with a section of ejector rod 4, and the;
