The invention relates to the field of building floor suspension devices, in particular to a self-locking device for a floor suspension bottom die. The self-locking device comprises an outer support box, a pin piece, a spring and an adjusting bolt, wherein the spring is fixed on the bottom surface of the outer support box; three ends are arranged on the pin piece; one end stretches out of the outer support box, the other end is connected with the spring, and a third end is rotationally fixed on the outer support box; and the adjusting bolt is fixed on the outer support box in a threaded connection manner. Before construction, a rectangular hole is reserved in a cross node of a splicing net rack; during suspension, only the bottom die is pushed upwards from the lower part of a splicing steel truss; the pin of the device is folded downwards due to resistance when pushed-in upwards; when the pin is pushed to the rectangular hole, the pin can be propped outwards under the action of the spring and inserted into the rectangular hole, so that the light bottom die can be locked on the splicing steel truss, the flatness of the height of the bottom die is adjusted by the aid of a screw rod, the reliability of the operation system and the working efficiency are high, and the construction quality is guaranteed.
Description
technical field [0001] The invention belongs to the field of building floor suspension devices, in particular to a self-locking device for floor suspension bottom molds. Background technique [0002] In the construction of the bottom mold suspended by the assembled grid frame of the building floor, the connection method between the bottom mold and the steel grid frame is a very critical step. Although there are many existing methods that can be selected, the current construction method has low system reliability, and the construction quality must be checked after construction, thereby affecting work efficiency. Contents of the invention [0003] The object of the present invention is to provide a self-locking device for floor suspension bottom formwork with strong system reliability, high work efficiency and guaranteed construction quality. [0004] In order to solve the above-mentioned technical problems, the technical scheme that the present invention takes is as follow...
