Further designed, the balance head is vertically downwards provided with a scale with scale marks.
Further, the number of the longitudinal connectors is two, and the longitudinal connectors are respectively arranged on the left side and the right side of the floor height control rod.
Further designed, the bottom of the floor height control rod is provided with a hook ear.
Further designed, the hook lug and the floor height control rod are arranged at 90 degrees.
Further designed, the upper part of the floor height control rod is provided with a hanging lug.
Further designed, threaded movable connections are respectively arranged between the horizontal rod and the balance head, between the balance head and the supporting rod, between the balance head and the scale, between the horizontal rod and the adjusting mechanism, between the fixed knob and the transverse connector, and between the story height control rod and the longitudinal connector.
Has the advantages that: the utility model has the advantages of reasonable design, convenient operation is swift, can adapt to the requirement of interval control between the not co-altitude reinforcing bar layer, and the precision of interval control between the reinforcing bar layer can reach the millimeter level to can practice thrift steel, circulated sustainable use. The using amount of the steel bars can be reduced by 0.22kg (the steel bar stirrup with the thickness of 100mm and the diameter of 10 is taken as an example) per square meter, and 22000kg of steel bars can be saved in 10 ten thousand square meters of residential districts; the development area of the national residences in 2018 of China is 822300 ten thousand square meters for calculation, and 1809060 tons of traditional stirrup steel bars can be saved if the method is applied to the popularization and application of the whole industry.
