[0002] In construction projects, post-cast strips are a common construction technology used to solve crack problems in large-volume concrete structures caused by temperature changes, shrinkage, and other reasons. Post-cast strips are usually set at key locations of the structure, and are poured after the main structure concrete reaches a certain strength to ensure the integrity and stability of the structure. Traditional post-cast strip formwork systems usually use six rows of frames on both sides as top supports, and construction is carried out in sections according to the areas divided by the post-cast strips.

[0003] However, although the above-mentioned traditional support methods have met the construction needs to a certain extent, the traditional post-cast strip support system requires a large amount of support materials. These materials are often not removed and circulated in time after the post-cast strip is poured, resulting in long-term backlog of materials, increasing construction costs and management difficulties. Moreover, since the post-cast strip support system needs to be constructed in sections and the support materials cannot be removed in time, the construction progress is seriously affected and the construction efficiency is low.

[0022] like Figure 1-Figure 3 , Figure 5-Figure 8 As shown, in order to reduce the pressure damage to the threads between the fine-tuning screw 7 and the sleeve 17 during use, a clamping assembly for clamping the fine-tuning screw 7 and linked with the locking pin 31 is provided on the inner side of the vertical rod 1, and the clamping assembly includes an inner rod 21 vertically movably arranged on the inner side of the vertical rod 1, and the upper end of the inner rod 21 is located on the inner side of the adjusting inner rod 6 and is movably connected to the adjusting inner rod 6, and the upper end side wall of the inner rod 21 is provided with a socket 22 corresponding to the through hole 16, and the end of the locking pin 31 away from the first driving assembly passes through the through hole 16 and the adjusting hole 14 and is plugged into the socket 22, and the longitudinal height of the inner side of the through hole 16 is greater than the longitudinal thickness of the locking pin 31, so that the locking pin 31 can press the inner rod 21 downward, and a driving column 25 is vertically movably arranged on the inner side of the lower end of the vertical rod 1, and a The clamping rod 12 is provided, and the side wall of the lower end of the vertical pole 1 is provided with a "U"-shaped clamping arm 10 which is movable along the radial direction of the vertical pole 1. In order to directly ensure the stability of the clamping arm 10, a first guide rod 27 corresponding to the clamping arm 10 is provided on the side wall of the vertical pole 1, and the clamping arm 10 is movably guided and connected to the outside of the first guide rod 27. The upper end side wall of the clamping arm 10 is provided with an inclined guide groove 28, and the upper end of the clamping arm 10 extends to the inner side of the vertical pole 1 and corresponds to the driving column 25.

[0023] Further, such as Figure 4 , Fig. 9 , Fig.10 As shown, in order to make the locking pin 31 tend to move downward, a bracket 15 located below the locking frame 9 is fixedly arranged between the multiple vertical poles 1, and a second elastic member 34 is arranged between the bracket 15 and the locking frame 9. In order to increase stability, a second guide rod 33 corresponding to the second elastic member 34 is arranged at the bottom of the locking frame 9. The second guide rod 33 passes through the bracket 15 and cooperates with the movable guide of the bracket 15. The second elastic member 34 is preferably a spring, and the spring is sleeved on the outside of the second guide rod 33.

[0024] like Figure 6-Figure 7As shown, in order to ensure the support of the inner rod 21 before pouring the post-cast strip, a first convex ring 24 is provided on the outer wall of the lower end of the inner rod 21, and a second convex ring 26 located below the first convex ring 24 is fixedly provided on the inner wall of the vertical rod 1, and a first elastic member 23 is provided between the first convex ring 24 and the second convex ring 26. The first elastic member 23 is preferably a spring, and the inner rod 21 can be supported by the first elastic member 23 to prevent the clamping arm 10 from clamping the fine-tuning screw 7 before pouring, thereby preventing the fine-tuning from being unable to be done.

[0025] In addition, if Figure 4 As shown, in order to facilitate the disassembly and assembly of the supporting top plate 2, a quick release sleeve 13 corresponding to the adjusting inner rod 6 is provided at the bottom of the supporting top plate 2. The quick release sleeve 13 is movably sleeved on the outer side of the upper end of the adjusting inner rod 6, and the quick release sleeve 13 and the adjusting inner rod 6 are locked by bolts.

[0026] like Figure 1-Figure 2 , Figure 4 As shown, in order to increase the stability between the fine-tuning screw 7 and the fixed base 3 and between the quick-release sleeve 13 and the supporting top plate 2, a stiffening plate 11 is welded and fixed between the side wall of the quick-release sleeve 13 and the bottom wall of the supporting top plate 2 and between the side wall of the lower end of the fine-tuning screw 7 and the bottom wall of the fixed base 3. The stiffening plate 11 is preferably triangular.

[0027] The present application also includes an adjustable construction engineering load post-casting strip support method. The above-mentioned adjustable construction engineering load post-casting strip support device is implemented, which includes the following steps: Step 1: Set a wooden board at the bottom of the post-cast strip to seal the post-cast strip area, measure the distance between the wooden board and the concrete structure layer below, and adjust the approximate position of the supporting top plate 2 through the coarse adjustment component according to the measured distance; Step 2: Stand up the pole 1, fix the base 3 on the concrete structure layer below, and align the supporting top plate 2 with the supporting wooden board at the bottom of the post-casting strip; Step 3: Use fine-tuning components to adjust the support top plate 2 to fit tightly against the bottom of the wooden board.

[0028] Working principle: when in use, a wooden board is placed at the bottom of the post-casting strip to seal the post-casting strip area. After subsequent pouring, the distance between the wooden board and the concrete structure layer below is measured. According to the measured distance, the position of the support top plate 2 is adjusted through the coarse adjustment component. Specifically, the second hand wheel 32 is turned to drive the winding wheel 35 to rotate, and the winding wheel 35 winds up the traction rope 36. The traction rope 36 pulls the locking pin 31 to move. At the same time, the third elastic member 37 is compressed, and the end of the third elastic member 37 is disengaged from the socket 22 and the adjustment hole 14. Then, the support top plate 2 is pushed and pulled to drive the adjustment inner rod 6 to move in the vertical pole 1. After the position is suitable, the adjustment hole 14 closest to the through hole 16 is matched with the through hole 16, and then it is loosened. The second hand wheel 32 and the second elastic member 34 are reset, and the locking pin 31 is pushed and inserted into the corresponding adjustment hole 14. Since the insertion hole 22 corresponds to the through hole 16, the end of the locking pin 31 enters the insertion hole 22. At this time, the adjustment inner rod 6 is locked, and then the upright pole 1 is placed vertically as a whole under the wooden board, and the fixed base 3 is attached to the concrete structure layer below, and the support top plate 2 is aligned with the wooden board. At this time, due to the supporting effect of the first elastic member 23, the inner rod 21 will not apply pressure to the driving column 25, and then the lower end of the clamping arm 10 will not clamp the clamping rod 12. Then the first hand wheel 19 is rotated to drive the second gear 20 to rotate, and the second gear 20 drives multiple sleeves 17 to rotate through the first gear 18, and then the fine-tuning screw 7 drives The vertical pole 1 rises until the supporting top plate 2 is attached to the bottom of the wooden board. At this time, the support is completed and the post-casting strip is poured on the top of the wooden board. Therefore, the supporting top plate 2 gradually bears the pressure of the concrete, and the supporting top plate 2 drives the adjusting inner rod 6 to press down. Since the longitudinal height of the inner side of the through hole 16 is greater than the longitudinal thickness of the locking pin 31, and a second elastic member 34 is provided between the locking frame 9 and the bracket 15, the adjusting inner rod 6 can drive the inner rod 21 to press down through the locking pin 31, and then the inner rod 21 continues to compress the first elastic member 23 and apply pressure to the driving column 25. The driving column 25 side applies pressure to the clamping arm 10 through the cooperation of the guide wheel 30 and the guide groove 28. The clamping arm 10 has a tendency to move toward the axial direction of the vertical pole 1, and then The lower end of the clamping arm 10 clamps the outside of the clamping rod 12, and the greater the pressure on the supporting top plate 2, the greater the pressure applied by the clamping arm 10 to the clamping rod 12, which can reduce the pressure on the threads between the fine-tuning screw 7 and the sleeve 17, thereby increasing the service life and facilitating subsequent recycling and reuse. The gravity of the poured concrete is used as the driving force, and the structure is compact and ingenious. At the same time, with the reasonable configuration of the coarse adjustment components and the fine adjustment components, not only stable support is achieved, but also it can be used as an independent return top to replace the traditional frame erection, which greatly increases the construction efficiency and saves material turnover costs, and also greatly increases the use space in the building, facilitates the passage of personnel and subsequent construction, can also adapt to different support heights, and is easy to disassemble and assemble.

It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
