Description

Technical Field

Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3The main structure of this embodiment includes: a semi-circular steel template 2, the semi-circular steel templates 2 are symmetrically arranged, and a first fixing bolt 3 is provided between the symmetrically arranged semi-circular steel templates 2. A reserved hole 4 is opened on the top surface of the semi-circular steel template 2. A fixing frame 5 is provided on the top surface of the semi-circular steel template 2, and a reserved groove 6 is opened on the fixing frame 5. A crossbeam 9 is provided at the position of the reserved groove 6, and a movable slot 10 is opened on the crossbeam 9. An embedded part 12 passes through the movable slot 10, and a second fixing bolt 11 is provided at the position of the embedded part 12. The second fixing bolt 11 locks the embedded part 12.

[0026] Semi-circular steel formwork 2 is made of steel plate;

[0027] In practical use, two semi-circular steel templates 2 are inserted into the foundation soil along with the fixed reinforcing bars 1. Then, the two semi-circular steel templates 2 are locked together by the first fixing bolt 3. At this time, the two semi-circular steel templates 2 are joined together to form a cylinder. Then, the fixing frame 5 is placed on the top surface of the semi-circular steel templates 2 and locked by the second positioning bolt 8. Using the reserved groove 6, the crossbeam 9 can be placed in the required position and then locked by the first positioning bolt 7.
