[0018] A method for using a formwork assembly for concrete construction includes the following steps:

[0019] S1. Adjust the corresponding height. Align the outer plug hole with the inner plug hole according to the required height, and then insert the plug shaft into the aligned outer plug hole and inner plug hole to fix the height. When the rotating rod is rotated, the rotating drum drives the two threaded columns to move closer or farther 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;

[0020] S2. Perform leveling assembly. After adjusting the required height, insert the shaft of the adjustment rod into the external socket, and install the end of the support rod and the latch shaft through the No. 2 latch (the latch shaft is at the middle bottom of the arm), so that the support frame is in a horizontal state, and the support assembly has a horizontal formwork.

[0021] S3. Change the tilt angle. Insert the shaft of the adjusting rod into the outer socket of the adjusting column (except the outer socket marked with horizontal) as required, and install the end of the support rod and the latch shaft through the No. 2 latch (the latch shaft here is at the middle bottom of the arm), then adjust the tilt angle of the support frame, and then the support assembly has the function of adjusting the tilt angle.

[0022] S4. Change the formwork for the beam. Insert the plug shaft of the adjusting rod into the external plug hole as required. At this time, you only need to flip the arm of the support rod in the opposite direction, and install the end of the adjusting rod and the pin shaft through the No. 2 pin (the pin shaft here is located at the end of the arm). At this time, the support frame is transformed from plane formwork to beam formwork.

[0023] S5. Change the edge-finishing formwork. Install the end of the support rod and the latch shaft through the No. 2 latch as needed (the latch shaft here is at the middle and bottom of the arm), keep one of the arms horizontal with the main rod, flip the other arm upward to form an angle, and then install the end of the support rod of the adjusting rod and the latch shaft through the No. 2 latch (the latch shaft here is at the end of the arm), so that the formwork assembly has the edge-finishing formwork.

[0024] S6. Adjust the size of the formwork. When the handle is turned, the telescopic rod is extended and retracted in the arm to change the support length of the support rod. By setting the convex prism, the convex prism and the arm 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.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The formwork assembly for concrete construction is first assembled by inserting the pillar of the fine-adjustment assembly into the socket, and then the support frame and the adjustment column can be assembled or disassembled through the plug shaft of the adjustment rod. Secondly, the support rod and the adjustment column can be assembled or disassembled through the No. 1 latch, and finally the adjustment rod and the support rod can be assembled or disassembled through the No. 2 latch, so that the support assembly is easy to disassemble and transport.

[0027] 2. For the formwork support component used in concrete construction, align the outer insertion hole with the inner insertion hole according to the required height, and then insert the insertion shaft into the aligned outer and inner insertion holes to fix the height. When the rotating rod is rotated, the rotating cylinder drives the two threaded columns to approach or move away from each other. Therefore, this formwork support component has the function of adjusting the height, and fine-tuning can be carried out according to the corresponding height.

[0028] 3. For the formwork support component used in concrete construction, after adjusting the required height, insert the insertion shaft of the adjusting rod into the outer insertion hole, and install the end of the supporting rod and the insertion pin shaft through the second insertion pin (the insertion pin shaft here is at the middle bottom of the arm rod), so that the support frame is in a horizontal state. Furthermore, this support component has the function of horizontal formwork support.

[0029] 4. For the formwork support component used in concrete construction, insert the insertion shaft of the adjusting rod into the outer insertion hole of the adjusting column according to the requirement (except for the outer insertion hole marked as horizontal), and install the end of the supporting rod and the insertion pin shaft through the second insertion pin (the insertion pin shaft here is at the middle bottom of the arm rod), then adjust the inclination angle of the support frame. Furthermore, this support component has the function of adjusting the inclination angle.

[0030] 5. For the formwork support component used in concrete construction, insert the insertion shaft of the adjusting rod into the outer insertion hole according to the requirement. At this time, only need to reverse the arm rod of the support rod. Install the end of the adjusting rod and the insertion pin shaft through the second insertion pin (the insertion pin shaft here is at the end of the arm rod). At this time, the support frame changes from plane formwork support to formwork support for the cross beam.

[0031] 6. For the formwork support component used in concrete construction, install the end of the supporting rod and the insertion pin shaft through the second insertion pin (the insertion pin shaft here is at the middle bottom of the arm rod). Keep one arm rod in horizontal formwork support with the main rod, then turn the other arm rod upward to form an angle. Then install the end of the supporting rod of the adjusting rod and the insertion pin shaft through the second insertion pin (the insertion pin shaft here is at the end of the arm rod). Furthermore, this formwork support component has the function of edge closing formwork support.

[0032] 7. For the formwork support component used in concrete construction, when the wrench is rotated, the telescopic rod is telescoped in the arm rod to change the support length of the support rod. Through the setting of the convex prism column, the convex prism is kept on the same horizontal plane as the arm rod to ensure the flatness of the support surface. Furthermore, this formwork support component can change the formwork size. Description of the Drawings

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0046] Please refer to Figure 1-10 , the present invention provides the following technical solutions:

[0047] A formwork support component for concrete construction, comprising a support frame 1 and a support base 2. The support frame 1 is located above the support base 2. The support frame 1 is composed of an outer bottom column 101 and an inner top column 102. A plurality of equally spaced inner insertion holes 103 are formed on the four sides of the inner top column 102;

[0048] An adjusting column 3 is sleeved on the outer surface of the inner top column 102. The adjusting column 3 is composed of a sleeve column 301 and a movable frame 302. The inside of the sleeve column 301 is a hollow structure. A plurality of equally spaced outer insertion holes 303 are formed on the four sides of the sleeve column 301. One of the outer insertion holes 303 is set as a horizontal hole, and the word "horizontal" is engraved below the outer insertion hole 303;

[0049] The sleeve column 301 is fixedly connected to the movable frame 302. The top of the movable frame 302 is movably connected to a support rod 5 through a first pin 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 be adapted to the main rod 501. Two insertion pins 505 are fixedly connected to the bottom of the arm rod 502. One of the insertion pins 505 is located at the middle bottom of the arm rod 502, and the other insertion pin 505 is located at the end of the arm rod 502;

[0050] The inner insertion hole 103 is adapted to the outer insertion hole 303. An adjusting rod 6 is inserted into the inner insertion hole 103 and the outer insertion hole 303. The adjusting rod 6 is composed of an insertion shaft 601 and a supporting rod 602. The supporting rod 602 is movably connected to the inside of the insertion shaft 601. The end of the supporting rod 602 is adapted to the insertion pin 505 through a second pin 7,

[0051] When the supporting rod 602 is used in cooperation with the insertion pin 505 in the middle of the arm rod 502, at this time, the main rod 501 and the arm rod 502 are transformed into a straight line form. When the supporting rod 602 is used in cooperation with the insertion pin 505 at the end of the arm rod 502, at this time, the main rod 501 and the arm rod 502 are transformed into a flipped state.

[0052] In the embodiment, when the formwork support component is used for formwork support, the formwork support is carried out by inconveniently adjusting the corresponding height; only need to assemble the adjusting column 3 onto the support frame 1, align the outer insertion hole 303 of the adjusting column 3 with the inner insertion hole 103 of the support frame 1 according to the corresponding height, and then insert the insertion shaft 601 of the adjusting rod 6 into the aligned outer insertion hole 303 and inner insertion hole 103 for fixing the height. Therefore, the height of the support frame 1 can be adjusted for support, and further the formwork support component has the function of adjusting the height.

[0053] When the formwork support component is used for formwork support, generally, leveling treatment cannot be carried out, and it does not have the function of setting leveling. The use scenario is limited (such as Figure 7as shown); when the support assembly adjusts the corresponding height, insert the insertion shaft 601 of the adjusting rod 6 into the outer insertion hole 303 at this time, and install the end of the supporting rod 602 and the insertion pin shaft 505 through the second insertion pin 7 (the insertion pin shaft 505 here is at the middle bottom of the arm rod 502), so that the support frame 1 is in a horizontal state, and then the support assembly has a horizontal formwork support.

[0054] When the support assembly forms a formwork, it usually does not have the adjustment of the formwork angle, and the use scenario is limited (such as Figure 8 as shown); only need to insert the insertion shaft 601 of the adjusting rod 6 into the outer insertion hole 303 of the adjusting column 3 (except the outer insertion hole 303 marked as horizontal), and install the end of the supporting rod 602 and the insertion pin shaft 505 through the second insertion pin 7 (the insertion pin shaft 505 here is at the middle bottom of the arm rod 502), the inclination angle of the support frame 1 can be adjusted, and then the support assembly has the function of adjusting the inclination angle.

[0055] When the support assembly forms a formwork, it usually cannot change the flat formwork into formwork for a cross beam (such as Figure 9 as shown); only need to insert the insertion shaft 601 of the adjusting rod 6 into the outer insertion hole 303, and at this time only need to reverse the arm rod 502 of the support rod 5, and install the end of the supporting rod 602 of the adjusting rod 6 and the insertion pin shaft 505 through the second insertion pin 7 (the insertion pin shaft 505 here is located at the end of the arm rod 502), at this time the support frame 1 changes from flat formwork to formwork for a cross beam, so the support assembly has the function of changing the form according to the required conditions.

[0056] When the formwork support assembly forms a formwork, it usually cannot change the flat formwork into edge trimming formwork (such as Figure 10 as shown); keep one of the arm rods 502 in horizontal formwork support with the main rod 501, only need to install the end of the supporting rod 602 of the adjusting rod 6 and the insertion pin shaft 505 through the second insertion pin 7 (the insertion pin shaft 505 here is at the middle bottom of the arm rod 502), then turn the other arm rod 502 upward to form an angle, and then install the end of the supporting rod 602 of the adjusting rod 6 and the insertion pin shaft 505 through the second insertion pin 7 (the insertion pin shaft 505 here is located at the end of the arm rod 502), and then the formwork support assembly has edge trimming formwork.

[0057] Refer to Figure 5 and Figure 6, a fine-tuning component 8 is arranged on the middle part of the upper surface of the support base 2 through a thrust bearing. The fine-tuning component 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 distances between the plurality of rotating rods 802 are equal. Two threaded columns 803 are threadedly connected to both the upper and lower ends of the rotating cylinder 801. Threads are provided on the two threaded columns 803, and the thread directions of the two threaded columns 803 are opposite. The rotating rod 802 drives the rotating cylinder 801 to rotate, and the rotating cylinder 801 drives the two threaded columns 803 to approach or move away from each other for height fine-tuning. The end of the threaded column 803 is fixedly connected with a round pad 804. The center of the upper surface of the round pad 804 is fixedly connected with a support column 805. A jack 9 is opened at the bottom end inside the support frame 1, and the jack 9 is located at the bottom end inside the outer bottom column 101. The support column 805 is adapted to the jack 9.

[0058] In the embodiment, when the formwork support component is used for formwork support, the corresponding height is usually adjusted for formwork support, and then fine-tuning is carried out according to the inconvenience of the corresponding height; first, the jack 9 of the support frame 1 is sleeved on the support column 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 cylinder 801 to rotate, and the rotating cylinder 801 drives the two threaded columns 803 to approach or move away from each other, thereby adjusting the height of the support component, and then fine-tuning is carried out according to the corresponding height.

[0059] In the embodiment, first, the support column 805 of the fine-tuning component 8 is inserted into the jack 9 for assembly, and then the support frame 1 and the adjusting column 3 can be assembled or disassembled through the insertion shaft 601 of the adjusting rod 6. Secondly, the support rod 5 and the adjusting column 3 can be assembled or disassembled through the first pin 4. Finally, the adjusting rod 6 and the support rod 5 can be assembled or disassembled through the second pin 7. Therefore, the support component is convenient for disassembly and transportation.

[0060] Refer to Figure 1 and Figure 4 , the inside of the arm rod 502 is a hollow structure, and a chute is opened at the top of the arm rod 502. The inside of the arm rod 502 is slidably connected with a telescopic rod 503. A convex prism is arranged at the top of the telescopic rod 503, and the convex prism is adapted to the chute. A wrench 506 is arranged at the end of the arm rod 502.

[0061] In the embodiment, when the formwork support component is used for formwork support, the formwork size usually cannot be changed and is limited by the application range; when the wrench 506 is rotated, the telescopic rod 503 is telescoped in the arm rod 502 to change the support length of the support rod 5. Through the arrangement of the convex prism, the convex prism is kept on the same horizontal plane as the arm rod 502 to ensure the flatness of the support surface. Therefore, the formwork support component can change the formwork size.

[0062] A method for using a formwork support component for concrete construction includes the following steps:

[0063] S1. Adjust the corresponding height. Align the outer socket 303 with the inner socket 103 according to the required height, and then insert the insertion shaft 601 into the aligned outer socket 303 and inner socket 103 to fix the height. When the rotating rod (802) is rotated, the rotating cylinder (801) drives the two threaded columns (803) to approach or move away from each other. Therefore, this formwork support assembly has the function of adjusting the height and can be finely adjusted according to the corresponding height.

[0064] S2. Perform leveling and assembly. After adjusting the required height, insert the insertion shaft 601 of the adjusting rod 6 into the outer socket 303, and install the end of the supporting rod 602 and the insertion pin shaft 505 with the second pin 7 (the insertion pin shaft 505 here is at the middle bottom of the arm rod 502), so that the support frame 1 is in a horizontal state. Thus, this support assembly has the function of horizontal formwork support.

[0065] S3. Change the inclination angle. Insert the insertion shaft 601 of the adjusting rod 6 into the outer socket 303 of the adjusting column 3 according to the requirement (except for the outer socket 303 marked as horizontal), and install the end of the supporting rod 602 and the insertion pin shaft (505) with the second pin 7 (the insertion pin shaft 505 here is at the middle bottom of the arm rod 502), then adjust the inclination angle of the support frame 1. Thus, this support assembly has the function of adjusting the inclination angle.

[0066] S4. Change the formwork support for the beam. Insert the insertion shaft 601 of the adjusting rod 6 into the outer socket 303 according to the requirement. At this time, only need to reverse the arm rod 502 of the supporting rod 5, and install the end of the supporting rod 602 and the insertion pin shaft 505 with the second pin 7 (the insertion pin shaft 505 here is at the end of the arm rod 502). At this time, the support frame 1 changes from flat formwork support to formwork support for the cross beam.

[0067] S5. Change the edge - closing formwork support. Install the end of the supporting rod 602 and the insertion pin shaft 505 with the second pin 7 (the insertion pin shaft 505 here is at the middle bottom of the arm rod 502). Keep one arm rod 502 in horizontal formwork support with the main rod 501, then turn the other arm rod 502 upward to form an angle, and then install the end of the supporting rod 602 of the adjusting rod 6 and the insertion pin shaft 505 with the second pin 7 (the insertion pin shaft 505 here is at the end of the arm rod 502). Thus, this formwork support assembly has the function of edge - closing formwork support.

[0068] S6. Adjust the formwork size. When the wrench 506 is rotated, the telescopic rod 503 extends or retracts in the arm rod 502 to change the support length of the supporting rod 5. Through the setting of the convex prism column, the convex prism is kept on the same horizontal plane as the arm rod 502 to ensure the flatness of the support surface. Thus, this formwork support assembly can change the formwork size.

[0069] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
