[0033] The following is combined with Figure 1-5 The utility model is described in further detail.

[0034] The utility model embodiment discloses a secondary structure construction column formwork-free device.

[0035] Reference Figure 1 , 2 The top plate 4 is a plurality of lower connecting plates 42, and the lower connecting plates 4 are connected to the bottom of the support frame 1, and the upper connecting plates 4 are connected to the bottom of the support frame 1.

[0036] Reference Figure 1 , 2 5. The bottom of the positioning plate 41 and the bottoms of several lower connecting plates 42 are provided with grooves, and the tops of several lower connecting plates 42 are provided with convex grooves matched with the grooves, and each convex groove is snapped into the inside of the corresponding groove. The lower connecting plates 42 are connected in series in a straight line through the connection of the grooves and the convex grooves, which is convenient for quickly removing the top plate 4 of the device. At the same time, after the motor drives the lead screw to rotate, the positioning plate 41 drives the series-connected lower connecting plates 42 to move up and down vertically. After the cylinder 8 is turned on, it moves horizontally in the direction close to the structural column 3.

[0037] Reference Figure 1 , 2 , 3, 5, a plurality of lower connecting plates 42 are fixedly connected to one side close to the base 1 with four fixing plates 5, each four corresponding fixing plates 5 are linearly arranged, and each two corresponding fixing plates 5 are rotatably connected to the inside with a telescopic rod 6, and the telescopic rod 6 is rotatably connected to the lower connecting plate 42 through the fixing plate 5, so that when the lower connecting plate 42 is in contact with the structural column 3, the bottom end of the telescopic rod 6 is in contact with the ground, so that the ground gives support force to the lower connecting plate 42, so that the lower connecting plate 42 is tightly attached to the structural column 3.

[0038] Reference Figure 1 , 25. Each telescopic rod 6 includes a rotating rod 61, a hollow rod 1 62 and a hollow rod 2 63. The rotating rod 61 can adjust the rotation angle so that the telescopic rods 6 of different lower connecting plates 42 will not cross each other. The hollow rod 1 62 slides inside the rotating rod 61 and the hollow rod 2 63 slides inside the hollow rod 1 62. The length of the telescopic rod 6 is adjusted by sliding as a whole, so that the lower connecting plates 42 with different heights can all obtain support from the ground. The outer surface of each hollow rod 1 62 is slidably connected to the inside of the corresponding rotating rod 61, and each hollow rod 2 63 is slidably connected to the inside of the corresponding hollow rod 1 62.

[0039] Reference Figure 1 , 2 5. A threaded hole 64 is provided on one side of each rotating rod 61, one side of each hollow rod 1 62 and one side of each hollow rod 2 63. Bolts are threadedly connected to the interior of some of the threaded holes 64. One end of some of the bolts is clamped on one side of the corresponding hollow rod 1 62, and one end of the other bolts is clamped on one side of the corresponding hollow rod 2 63. When the overall distance between the rotating rod 61, the hollow rod 1 62 and the hollow rod 2 63 is appropriate, the corresponding hollow rod 1 62 and the hollow rod 2 63 are clamped by tightening the bolts so that the hollow rods 61, 62 and 63 are in a proper position. Rod 1 62 and hollow rod 2 63 cannot slide at will. When adjustment is needed, loosen the corresponding bolts and continue to slide hollow rod 1 62 and hollow rod 2 63. Similarly, when disassembling, loosen the corresponding bolts, and tighten the bolts after hollow rod 1 62 is completely retracted into the interior of rotating rod 61. Tighten the bolts after hollow rod 2 63 is completely retracted into the interior of hollow rod 1 62. At this time, the lower connecting plate 42 no longer supports the clamping structural column 3. The height of the lower connecting plate 42 is different. Some telescopic rods 6 have hollow rod 2 63, and some telescopic rods 6 do not have hollow rod 2 63.

[0040] Reference Figure 3 , 4 One side of the sliding seat 2 is fixedly connected with a slider and two limit rods 7. After starting the cylinder 8, the two limit rods 7 make the top plate 4 move left and right in a straight line in the horizontal direction to prevent the top plate 4 from rotating and preventing the top plate 4 from driving the lower connecting plate 42 to rotate and touch the top of the building. One side of the sliding seat 2 is fixedly connected with a cylinder 8, and the cylinder 8 can drive the top plate 4 to move toward or away from the structural column 3. The two limit rods 7 include a fixed rod and a sliding rod. The outer surface of each sliding rod is slidably connected to the inside of the corresponding fixed rod. One end of the two sliding rods and the end of the output shaft of the cylinder 8 are fixedly connected to one side of the positioning plate 41.

[0041] Reference Figure 3 , 4A slide groove is provided on one side of the base 1, and a lead screw is rotatably connected inside the slide groove. A gear 2 is fixedly connected to the bottom of the lead screw. A motor is fixedly connected to one side of the base 1, and a gear 1 is fixedly connected to the end of the motor output shaft. The teeth of gear 1 are meshed with the teeth of gear 2. The motor drives the lead screw to rotate through two gears 1 and 2 that are meshed at right angles, thereby causing the slider to move up and down in the vertical direction inside the slide groove, so that the sliding seat 2 drives the top plate 4 to move up and down in the vertical direction, that is, changes the height of the top plate 4.

[0042] Reference Figure 1 , 2 , 3, 4, 5, a counterweight block 9 is overlapped on one side of the base 1. When the top plate 4 is high enough and the number of lower connecting plates 42 is sufficient, the overall center of gravity of the device changes. In order to prevent the device from tipping over, the overall center of gravity of the device is changed by the counterweight block 9 so that the device maintains stability. A universal wheel is fixedly connected to the bottom of the base 1, which facilitates the movement of the base 1.

[0043] The implementation principle of the secondary structure construction column formwork-free device of the utility model embodiment is:

[0044] 1. After the construction of the structural column 3 is completed, two devices are placed on both sides of the structural column 3 that are exposed and not in contact with the wall, and the two devices are adjusted to a suitable distance. Then, the motor is started, so that the sliding seat 2 drives the top plate 4 to move to a suitable height, and the lower connecting plate 42 is connected. Then, the motor is started again, so that the sliding seat 2 drives the top plate 4 to move to a suitable height, and the lower connecting plate 42 is connected, until the bottom of the lowest lower connecting plate 42 is in contact with the ground, or reaches a specified height;

[0045] 2. Start the cylinder 8 until the top plate 4 is in contact with the structural column 3, rotate the rotating rod 61 of the telescopic rod 6 to a suitable angle, loosen the bolts, and slide the hollow rod 1 62 and the hollow rod 2 63 toward the ground until the bottom of the hollow rod 2 63 or the bottom of the hollow rod 1 62 touches the ground, then tighten the bolts, and push the stretched telescopic rod 6 toward the structural column 3;

[0046] 3. After the construction of the structural column 3 is completed, push the base 1 so that the top plate 4 is no longer in contact with the structural column 3, loosen the bolts, retract the telescopic rod 6, and then remove the lower connecting plate 42 from bottom to top. The installed device can also be directly pushed to the next structural column 3 to continue construction. If the height is appropriate, directly start the cylinder 8 to adjust the length of the telescopic rod 6 and clamp the next structural column 3. If the height is not appropriate, remove or add a certain number of lower connecting plates 42, continue to start the cylinder 8 to adjust the length of the telescopic rod 6, and clamp the next structural column 3.

[0047] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
