[0031] The inside of the positioning groove 22 is provided with a positioning member 23, the positioning member 23 comprises a connecting knob 231 located at the notch of the steel formwork body 1, the output end of the connecting knob 231 is connected with a driving gear 233 through a rotating shaft 232, the outer periphery of the driving gear 233 is connected with two groups of fixed bolt rods 235 through a driven member 234, so that the connecting knob 231 controls the fixed bolt rod 235 to move out of the inside of the positioning groove 22 through the driven member 234. The driven member 234 comprises two groups of driven gears 2341 engaged with the driving gear 233, two groups of transmission shaft rods 2342 are arranged at the driven gears 2341, the transmission shaft rods 2342 are connected in the positioning groove 22 through a linking sleeve 2343; the outer diameter of the transmission shaft rod 2342 is matched with the fixed bolt rod 235, the fixed bolt rod 235 is provided with an inner thread on one side of the transmission shaft rod 2342 for connecting the transmission shaft rod 2342, an outer thread matched with the inner thread is arranged on the outer periphery of the transmission shaft rod 2342, so that the transmission shaft rod 2342 is connected with the transmission shaft rod 2342 through the outer thread; the two ends of the fixed bolt rod 235 are provided with limiting protrusions 2351, and the limiting protrusions 2351 are arranged in an arc shape.
[0032] The bottom end of the positioning member 23 extends to the upper part of the steel formwork body 1, so that the positioning member 23 leaks out from the notch through the steel formwork body 1.
[0033] The lower end of the steel formwork body 1 is provided with a linking part 3; the linking part 3 comprises a concave groove 31 located at the lower end of the steel formwork body 1 for inserting the inserting part 2, and a fixing groove 32 is arranged in the concave groove 31 for connecting the fixed bolt rod 235, so that the inserting part 2 is inserted into the concave groove 31 and connected to the fixing groove 32 through the fixed bolt rod 235.
[0034] The inserting part 2 and the linking part 3 are matched with each other, so that the two groups of steel formwork bodies 1 are connected end to end.
[0035] The shape of the inserting seat 21 is a semicircular arc, and the end face of the inserting seat 21 is rectangular.
[0036] The working principle of the combined steel formwork provided by the utility model is as follows:
[0037] Place the two groups of steel formwork bodies 1 at the position where they need to be spliced, and ensure that the inserting parts 2 and the linking parts 3 of the two groups of steel formwork bodies 1 are aligned.
[0038] The insertion part 2 of one set of steel formwork bodies 1 is aligned with the connection part 3 of another set of steel formwork bodies 1, and the insertion seat 21 is inserted into the concave groove 31. During the insertion process, the shape of the insertion seat 21 matches the concave groove 31, so that the insertion part 2 can smoothly enter the connection part 3.
[0039] During the insertion of the insertion seat 21 into the concave groove 31, the positioning groove 22 corresponds to the fixing groove 32. At this time, the rotating connecting knob 231 is rotated, and the driving gear 233 is driven to rotate through the rotating shaft 232. The driving gear 233 meshes with the driven gear 2341, thereby driving the two sets of driven gears 2341 to rotate. The driven gear 2341 drives the transmission shaft rod 2342 to rotate, and since the transmission shaft rod 2342 and the fixed pin rod 235 are matched with each other through internal threads and external threads, the rotation of the transmission shaft rod 2342 will make the fixed pin rod 235 move outwards from the inside of the positioning groove 22 and enter the fixing groove 32, realizing the fixed connection of the insertion part 2 and the connection part 3. At the same time, the limiting protrusions 2351 at both ends of the fixed pin rod 235 move in the guide groove 25, ensuring the linear movement and accurate positioning of the fixed pin rod 235.
[0040] When the fixed pin rod 235 is completely moved out of the positioning groove 22 and enters the fixing groove 32, the two sets of steel formwork bodies 1 are connected end to end, which are used to build corresponding wall bodies, column bodies and the like. When disassembly is required, the connecting knob 231 is rotated in the opposite direction, so that the fixed pin rod 235 is retracted into the positioning groove 22, and the insertion part 2 can be pulled out of the connection part 3, thereby completing the disassembly.
[0041] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
