The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up the construction progress and reduce the project cost. The building formwork needs to be supported by a support frame when in use.

[0003] After searching, the announcement number CN213297164U is a formwork support bracket for construction, which includes a first support rod, a first connecting rod and a second support rod that are threaded together from top to bottom. The surface of the first support rod is sleeved with a first movable sleeve and a first fixed block is fixedly connected to the top of the first support rod. The surface of the first fixed block is hinged with a first cross bar distributed in an annular manner. The surface of the first movable sleeve is hinged with a first inclined rod distributed in an annular manner. The end of the first inclined rod away from the first movable sleeve is hinged to the first cross bar. The surface of the second support rod is sleeved with a second movable sleeve and a second fixed block is fixedly connected to the bottom of the second support rod.

[0004] Based on the above patent, the problems of inconvenient transportation and large floor space occupied are solved through a detachable and foldable setting. However, during use, it is inconvenient to adjust the height, and the support and disassembly process is relatively difficult. Since the entire device is vertically located between the ground and the formwork, after bearing the weight of the concrete, it is difficult to remove the device from between the ground and the formwork during disassembly due to problems such as large friction and resistance.

A plurality of slots 14 are provided on the outer side of the limit ring 13, and a transfer block 15 is fixedly connected to the outer side of the threaded ring 4. The inner side of the connecting block 15 is rotatably connected to a rotating handle 16, and the middle section of the rotating handle 16 is embedded in the inside of the card slot 14. The ends of the support rod 1 and the telescopic rod 2 are provided with openings 5, and the ends of the support rod 1 and the telescopic rod 2 are provided with fixed through-holes 6 corresponding to the positions of the openings 5. The outer sides of the ends of the support rod 1 and the telescopic rod 2 are provided with support plates 7, and the middle parts of the opposite sides of the support plates 7 are fixedly connected to connecting blocks 8. The outsides of the connecting blocks 8 are respectively rotatably connected to the ends of the support rod 1 and the telescopic rod 2. The opposite sides of the support plates 7 are fixedly connected with arc plates 9, and the upper ends of the arc plates 9 are movably connected to the inside of the opening 5. A plurality of adjustment holes 10 are provided in the middle of the arc plates 9, and a fixing bolt 11 is commonly provided inside the adjustment holes 10 and the fixing through-holes 6.

[0027] When supporting the top formwork, the device is placed on the ground and kept perpendicular to the ground. The threaded ring 4 is driven to rotate by the rotating handle 16. The rotating threaded ring 4 cooperates with the threaded area 3 to drive the telescopic rod 2 to rise, and the support plate 7 at the top of the telescopic rod 2 is in contact with the bottom of the formwork for support. The rotating handle 16 is turned downward to make the rod body of the rotating handle 16 embedded in the card slot 14 to prevent the threaded ring 4 from rotating during the pouring process. When disassembling the device, the rotating handle 16 is turned upward to separate it from the card slot 14. The threaded ring 4 is driven to rotate in the opposite direction by the rotating handle 16 to make the telescopic rod 2 descend, drive the top support plate 7 to separate from the formwork, and facilitate disassembly, thereby avoiding the effect of the poured concrete gravity on the device. When the fixing holes 10 on the curved plate 9 correspond to the fixed through holes 6, and the fixing holes 11 are reinserted, a certain angle can be maintained between the support plate 7 and the support rod 1 and the telescopic rod 2.

A plurality of anti-slip spikes 23 are fixedly connected to the lower side of the lower support plate 7.

[0029] By rotating the rotating plate 20 in the receiving groove 19 by 180 degrees, the end of the rotating plate 20 can be exposed from the supporting plate 7, increasing the contact area with the template. The anti-slip spikes 23 provided can increase the friction with the ground. The fixed ears 22 provided can be fixed to the ground by fixing parts to avoid accidental displacement of the device.

[0030] Working principle: When supporting the top formwork, place the device on the ground and keep it perpendicular to the ground. The threaded ring 4 is driven to rotate by the rotating handle 16. The rotating threaded ring 4 cooperates with the threaded area 3 to drive the telescopic rod 2 to rise, and make the support plate 7 on the top of the telescopic rod 2 contact with the bottom of the formwork for support. Turn the rotating handle 16 downward so that the rod body of the rotating handle 16 is embedded in the card slot 14 to prevent the threaded ring 4 from rotating during the pouring process; when supporting the side wall, pull out the fixing bolt 11, rotate the support plate 7 to maintain a certain angle with the support rod 1 and the telescopic rod 2, and then reinsert the fixing bolt 11 into the adjustment hole 10 and the fixed through-hole 6 to fix the support plate 7 and the fixed through-hole 6 so that the support rod 1 and the telescopic rod 2 maintain a certain inclination angle with the ground to support the side formwork.
