Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-3, the present utility model provides a technical solution: a simple device suitable for controlling the thickness of a cast-in-place concrete floor, comprising an aluminum formwork 1, and a communication hole 2 is formed through the middle of the aluminum formwork 1, and the communication hole The interior of 2 is movably plugged with a positioning bolt 3, the top of the positioning bolt 3 is fixedly installed with a steel plate 4, one end of the positioning bolt 3 located at the top of the aluminum formwork 1 is movably sleeved with a sleeve 5, and the upper surface of the aluminum formwork 1 is movably cast with a floor slab. The main body 6, one end of the positioning bolt 3 located at the bottom of the aluminum template 1 is movably sleeved with a mountain-shaped clip 7, and the bottom end of the positioning bolt 3 is threadedly sleeved with a fixing nut 8.

The steel plate 4 and the positioning bolts 3 are fixedly connected by welding, and the weld bead should not be too large to prevent the weld bead from hindering the sleeve connection of the casing 5, thereby affecting the height control of the floor body 6.
