7. The building floor repair aid of claim 6, wherein the sliding block is provided with a locking member for locking the relative position of the winding mechanism and the guide rod or unlocking the winding mechanism.
8. A building floor repair assisting device as claimed in claim 1, wherein the winding mechanism comprises a winding bracket, a winding roller and a driving handle, one end of the flexible cable is wound on the winding roller, the winding roller is mounted on the winding bracket, the winding mechanism is connected with the guide rod, the driving handle is connected with the winding roller, and the winding roller is provided with a ratchet wheel at a position matched with the winding bracket for locking or unlocking the rotation of the winding roller relative to the winding bracket.
9. The building floor repair aid of claim 1, wherein the end of the flexible cable away from the winding mechanism is provided with a hook, and the hooks of the flexible cables corresponding to the two winding mechanisms are symmetrically arranged and hooked at the same position of the repair structure for counteracting the horizontal force.
10. A method for repairing a floor of a building using the building floor repair aid of any one of claims 1 to 9, comprising the steps of:
respectively driving anchor rods into the building outer walls of the plane of the floor to be repaired and the plane of the upper floor, wherein the anchor rods extend into the floor of the building, arranging guide rods in pairs and enabling the guide rods to be symmetrically arranged relative to the repairing structure, and arranging a support rod for each guide rod;
each guide rod is connected with at least two winding mechanisms in a sliding way, different winding mechanisms on the same guide rod are respectively connected with different positions of the repairing structure, and the winding mechanisms on the symmetrical guide rods are symmetrically arranged and connect the corresponding flexible cables to the same position of the repairing structure;
adjusting the position of the winding mechanism relative to the guide rod, tensioning the flexible cable suspension repairing structure, and respectively adjusting the winding mechanism to adjust the sagging state of the reinforcing mesh of the repairing structure and the distance between the bottom plate of the repairing structure and the reinforcing mesh;
and pouring concrete at the repairing position, waiting for solidification and molding, maintaining to the required strength, cutting off the flexible cable along the level position of the floor, and removing the suspension bracket and the winding mechanism.
