Example 1

As shown in fig. 1-3, the utility model provides a retractable's concrete floor formwork structure, including two support frames 1 and a carriage 2, carriage 2 sets up between two support frames 1, and support frame 1 includes two parallel arrangement's the pole 11 of glancing at the top and the pole 12 of glancing at down, on every the pole 11 of glancing at the top equal sliding connection threaded rod 5, two lock nut 51 are connected to equal screw-thread fit on every threaded rod 5, and two lock nut 51 set up respectively in the upper and lower both sides of the pole 11 of corresponding glancing at the top. Each of the upper threaded rod 11 and the lower threaded rod 12 is composed of a metal rod 3 and a rectangular supporting tube 4, one end of the metal rod 3 opposite to the supporting tube 4 is welded and fixed, a sliding hole is formed in each metal rod 3, each threaded rod 5 is connected in a sliding mode in the corresponding sliding hole in the metal rod 3, and two locking nuts 51 on each threaded rod 5 are arranged on the upper side and the lower side of the corresponding metal rod 3 respectively. The support height of the support frame 1 can be changed by moving the two metal rods 3 up and down along the threaded rod 5. After the supporting frame 1 is moved to the required supporting height, the two locking nuts 51 tightly abut against the upper and lower sides of the metal rod 3 by rotating the locking nuts 51 on the upper and lower sides of the metal rod 3, so that the supporting height of the supporting frame 1 is fixed. Every goes up and is equipped with bearing structure between xuan pole 11 and the lower xuan pole 12, and bearing structure includes a plurality of web members 6, and web members 6 adopt similar rod-shaped materials such as angle steel, steel pipe, steel sheet to make and form. The upper end and the lower end of each web member 6 are respectively welded and fixed between the upper corrugated rod 11 and the lower corrugated rod 12, and a certain included angle is formed between every two adjacent web members 6. The plurality of web members 6 obliquely disposed between the upper and

lower tension rods

11 and 12 can enhance the supporting strength between the upper and

lower tension rods

11 and 12, thereby improving the supporting strength of the entire supporting frame 1. The lower end of each threaded rod 5 is welded with a fixed backing plate 7. The base plate 7 is directly placed on a wing plate of an I-shaped steel beam between floors.
