U-shaped bracket capable of being fast dismounted
The invention relates to a U-shaped bracket capable of being fast dismounted. The U-shaped bracket comprises six parts including a U-shaped disc, a sleeve, a slide block, a positioning pin, a large lead screw and a large screw nut, wherein the U-shaped disc is welded on the sleeve; the slide block is welded on the large lead screw and is then inserted into the sleeve through a round hole formed in the U-shaped disc; two salient points of the slide block rotate for 90 degrees through two notches of the U-shaped disc and are clamped into two slideways of the sleeve; the large screw nut is screwed on the large screw rod; the positioning pin is inserted into a positioning hole of the sleeve; and the U-shaped bracket capable of being fast dismounted is formed. The U-shaped bracket has the advantages that during the formwork erection, the slide block moves to the lower end of the slideway; the positioning groove is just aligned with the positioning hole; the positioning pin is inserted into the positioning hole; during the formwork dismounting, the positioning pin is knocked, and the U-shaped disc and the sleeve fast fall down; the fast dismounting is realized; and the stress mode is a vertical stress mode.
