[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0029] See also Figure 1-10 , the present invention provides the following technical solutions: A formwork assembly for concrete construction, comprising a support frame 1 and a support seat 2, wherein the support frame 1 is located above the support seat 2, the support frame 1 is composed of an outer bottom column 101 and an inner top column 102, and a plurality of equidistant inner plug holes 103 are provided on four sides of the inner top column 102; The outer surface of the inner top column 102 is sleeved with an adjustment column 3, which is composed of a sleeve column 301 and a movable frame 302. The interior of the sleeve column 301 is a hollow structure, and a plurality of equidistant external plug holes 303 are opened on the four sides of the sleeve column 301. One of the external plug holes 303 is set as a horizontal hole, and the word "horizontal" is engraved below the external plug hole 303; The sleeve column 301 is fixedly connected to the movable frame 302. The top of the movable frame 302 is movably connected to the support rod 5 through a No. 1 latch 4. The support rod 5 is composed of a main rod 501, an arm rod 502 and a telescopic rod 503. The end of the main rod 501 is movably connected to the arm rod 502 through a hinge 504. A space is left at the end of the arm rod 502 to adapt to the main rod 501. The bottom of the arm rod 502 is fixedly connected to two latch shafts 505, one of which is located at the middle bottom of the arm rod 502, and the other latch shaft 505 is located at the end of the arm rod 502; The inner plug hole 103 is matched with the outer plug hole 303. The inner plug hole 103 and the outer plug hole 303 are inserted with an adjustment rod 6. The adjustment rod 6 is composed of an insertion shaft 601 and a support rod 602. The support rod 602 is movably connected inside the insertion shaft 601. The end of the support rod 602 is matched with the bolt shaft 505 through the second bolt 7. When the support rod 602 is used in conjunction with the latch shaft 505 at the middle of the arm rod 502, the main rod 501 and the arm rod 502 are transformed into a straight state. When the support rod 602 is used in conjunction with the latch shaft 505 at the end of the arm rod 502, the main rod 501 and the arm rod 502 are transformed into a flipped state.

[0030] In the embodiment, when the formwork assembly is performing formwork, the formwork is performed by inconveniently adjusting the corresponding height; it only needs to assemble the adjusting column 3 onto the support frame 1, align the outer plug hole 303 of the adjusting column 3 with the inner plug hole 103 of the support frame 1 according to the corresponding height, and then insert the plug shaft 601 of the adjusting rod 6 into the aligned outer plug hole 303 and inner plug hole 103 to fix the height, so that the height of the support frame 1 can be adjusted for support, thereby enabling the formwork assembly to have the function of adjusting the height.

[0031] When the formwork component is used for formwork, it is usually not possible to perform leveling, and does not have the function of setting leveling. The usage scenarios are limited (such as Figure 7 As shown); when the support assembly adjusts the corresponding height, the plug shaft 601 of the adjustment rod 6 is inserted into the external plug hole 303, and the end of the support rod 602 is installed with the latch shaft 505 through the second latch 7 (the latch shaft 505 is at the middle bottom of the arm 502), so that the support frame 1 is in a horizontal state, and then the support assembly has a horizontal formwork.

[0032] When the support assembly is used for formwork, the formwork angle is usually not adjustable, and the use scenarios are limited (such as Figure 8As shown); it is only necessary to insert the plug shaft 601 of the adjustment rod 6 into the outer plug hole 303 of the adjustment column 3 (except the outer plug hole 303 marked with horizontal), and install the end of the support rod 602 and the pin shaft 505 through the second pin 7 (the pin shaft 505 is at the middle bottom of the arm 502), so as to adjust the inclination angle of the support frame 1, and thus the support assembly has the function of adjusting the inclination angle.

[0033] When this support assembly is used for formwork, it is usually not possible to convert the plane formwork into beam formwork (e.g. Fig. 9 As shown); it is only necessary to insert the plug shaft 601 of the adjusting rod 6 into the external plug hole 303. At this time, it is only necessary to flip the arm 502 of the support rod 5 in the opposite direction, and install the end of the support rod 602 of the adjusting rod 6 with the latch shaft 505 through the second latch 7 (the latch shaft 505 here is located at the end of the arm 502). At this time, the support frame 1 is transformed from a plane formwork to a beam formwork. Therefore, the support component has the function of changing its shape according to the required conditions.

[0034] When this formwork assembly is used for formwork, it is usually not possible to convert the flat formwork into the edge formwork (such as Fig.10 As shown); keep one of the arm rods 502 and the main rod 501 horizontal to support the formwork, and only need to install the end of the support rod 602 of the adjustment rod 6 and the latch shaft 505 through the No. 2 latch 7 (the latch shaft 505 here is at the middle and bottom of the arm rod 502), and then flip the other arm rod 502 upward to form an angle, and then install the end of the support rod 602 of the adjustment rod 6 and the latch shaft 505 through the No. 2 latch 7 (the latch shaft 505 here is at the end of the arm rod 502), so that the formwork assembly has the function of edge support.

[0035] See also Figure 5 and Figure 6 A fine-tuning assembly 8 is provided in the middle of the upper surface of the support seat 2 through a thrust bearing. The fine-tuning assembly 8 includes a rotating cylinder 801. A plurality of rotating rods 802 are fixedly connected to the outer surface of the rotating cylinder 801, and the spacing between the plurality of rotating rods 802 is equal. Two threaded columns 803 are threadedly connected to the upper and lower ends of the rotating cylinder 801. The two threaded columns 803 are provided with threads, and the threads of the two threaded columns 803 are rotated in opposite directions. The rotating rod 802 drives the rotating cylinder 801 to rotate, and the rotating cylinder 801 drives the two threaded columns 803 to move closer or farther away for height fine-tuning. A round pad 804 is fixedly connected to the end of the threaded column 803, and a pillar 805 is fixedly connected to the center of the upper surface of the round pad 804. A socket 9 is provided at the bottom end of the interior of the support frame 1. The socket 9 is located at the bottom end of the interior of the outer bottom column 101, and the pillar 805 is adapted to the socket 9.

[0036] In an embodiment, when the formwork assembly is performing formwork, the corresponding height of the formwork is usually adjusted, and then fine-tuning is performed according to the corresponding height; first, the socket 9 of the support frame 1 is sleeved on the pillar 805, and the round pad 804 supports the support frame 1. When the rotating rod 802 is rotated, the rotating rod 802 drives the rotating drum 801 to rotate, and the rotating drum 801 drives the two threaded columns 803 to move closer or farther away from each other, thereby adjusting the height of the support assembly, and then fine-tuning is performed according to the corresponding height.

[0037] In the embodiment, first, the support column 805 of the fine-tuning assembly 8 is inserted into the socket 9 for assembly, and then the support frame 1 and the adjusting column 3 can be assembled or disassembled through the plug shaft 601 of the adjusting rod 6. Secondly, the support rod 5 and the adjusting column 3 can be assembled or disassembled through the No. 1 latch 4. Finally, the adjusting rod 6 and the support rod 5 can be assembled or disassembled through the No. 2 latch 7, so that the support assembly is easy to disassemble and transport.

[0038] See also Figure 1 and Figure 4 The interior of the arm 502 is a hollow structure, and a slide groove is provided on the top of the arm 502. The interior of the arm 502 is slidably connected to the telescopic rod 503. A convex prism is provided on the top of the telescopic rod 503, and the convex prism is adapted to the slide groove. A screw handle 506 is provided at the end of the arm 502.

[0039] In an embodiment, when the formwork assembly is performing formwork, the size of the formwork cannot usually be changed and the scope of use is limited; when the handle 506 is turned, the telescopic rod 503 is telescoped on the arm 502 to change the support length of the support rod 5. By setting the convex prism, the convex prism and the arm 502 are maintained at the same horizontal plane to ensure that the support surface is flat, and the formwork assembly can change the size of the formwork.

[0040] A method for using a formwork assembly for concrete construction comprises the following steps: S1. Adjust the corresponding height. Align the outer plug hole 303 with the inner plug hole 103 according to the required height, and then insert the plug shaft 601 into the aligned outer plug hole 303 and the inner plug hole 103 to fix the height. When the rotating rod (802) is rotated, the rotating cylinder (801) drives the two threaded columns (803) to move closer to or away from each other. Therefore, the formwork assembly has the function of adjusting the height, and fine-tuning is performed according to the corresponding height.

[0041] S2. Perform leveling assembly. After adjusting the required height, insert the plug shaft 601 of the adjustment rod 6 into the external plug hole 303, and install the end of the support rod 602 and the latch shaft 505 through the second latch 7 (the latch shaft 505 is at the middle bottom of the arm 502), so that the support frame 1 is in a horizontal state, and the support assembly has a horizontal formwork.

[0042] S3. Change the tilt angle. Insert the plug shaft 601 of the adjustment rod 6 into the outer plug hole 303 of the adjustment column 3 (except the outer plug hole 303 marked with horizontal) as required, and install the end of the support rod 602 and the latch shaft (505) through the second latch 7 (the latch shaft 505 is at the middle bottom of the arm 502). Then adjust the tilt angle of the support frame 1, and then the support assembly has the function of adjusting the tilt angle.

[0043] S4. Change the formwork for the beam. Insert the plug shaft 601 of the adjusting rod 6 into the external plug hole 303 as required. At this time, you only need to flip the arm 502 of the supporting rod 5 over, and install the end of the supporting rod 602 and the latch shaft 505 through the No. 2 latch 7 (the latch shaft 505 here is located at the end of the arm 502). At this time, the support frame 1 is changed from plane formwork to beam formwork.

[0044] S5. Change the edge-finishing formwork. Install the end of the support rod 602 and the latch shaft 505 through the No. 2 latch 7 as needed (the latch shaft 505 here is at the middle and bottom of the arm 502), keep one of the arm rods 502 and the main rod 501 horizontal for formwork, and then flip the other arm rod 502 upward to form an angle, and then install the end of the support rod 602 of the adjustment rod 6 and the latch shaft 505 through the No. 2 latch 7 (the latch shaft 505 here is at the end of the arm 502), so that the formwork assembly has the edge-finishing formwork.

[0045] S6. Adjust the size of the formwork. When the handle 506 is turned, the telescopic rod 503 is extended and retracted on the arm 502 to change the support length of the support rod 5. By setting the convex prism, the convex prism and the arm 502 are kept in the same horizontal plane to ensure the flatness of the supporting surface, so that the formwork assembly can change the size of the formwork.
