Description

Technical Field

[0001] The invention relates to the field of construction engineering, and in particular to an adjustable construction engineering load post-casting belt supporting device and a supporting method. Background Art

[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. Previously, the support system of the post-cast strip was usually more complicated and occupied a larger space, resulting in inconvenience in traffic on the construction site and affecting the smooth progress of other processes.

Detailed implementation manner

[0037] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0038] As Figures 1 - 2 、 Figure 11 shown, an adjustable post-cast strip support device for building engineering loads includes three vertically arranged poles 1 distributed in a circular array. The pole 1 is a hollow structure, preferably a steel pipe. A horizontal plate 4 is fixedly connected by welding between adjacent poles 1. There are multiple groups of horizontal plates 4, and multiple groups of horizontal plates 4 are evenly distributed along the height direction of the pole 1. An inclined diagonal tension plate 5 is fixedly arranged by bolts between adjacent horizontal plates 4 in the height direction. The diagonal tension plate 5, the horizontal plate 4, and the pole 1 form a triangular structure to ensure stability.

A fixed base 3 is horizontally arranged below the pole 1, and the fixed base 3 is used to fit on the concrete structural layer under the water surface of the post-cast strip;

[0039] As Figures 1 - 4 、 Figures 9 - 10As shown in the figure, in order to adapt to different support heights, a coarse adjustment component is provided at the upper end of the vertical rod 1. The coarse adjustment component includes an adjustment inner rod 6 that is movably inserted into the inner side of the upper end of the vertical rod 1. The support top plate 2 is arranged at the upper ends of a plurality of adjustment inner rods 6. Adjustment holes 14 are evenly arranged on the side wall of the adjustment inner rod 6. A through hole 16 corresponding to the adjustment hole 14 is arranged on the side wall of the upper end of the vertical rod 1. A locking pin 31 for plugging and matching with the through hole 16 and the adjustment hole 14 is arranged on the side surface of the upper end of the vertical rod 1. A first driving component for driving the displacement of the locking pin 31 is arranged between a plurality of vertical rods 1. The first driving component includes a locking frame 9 arranged between a plurality of vertical rods 1 and corresponding to the locking pin 31. The locking frame 9 is a hollow structure. A sliding groove 39 corresponding to the locking pin 31 one by one is arranged on the side surface of the locking frame 9. The locking pin 31 is movably and guidingly connected with the sliding groove 39. A winding wheel 35 is rotatably arranged in the middle of the inner side of the locking frame 9. A second hand wheel 32 for driving the rotation of the winding wheel 35 is arranged at the upper end of the locking frame 9. A traction rope 36 corresponding to the locking pin 31 one by one is fixed to the side surface of the winding wheel 35. A stop baffle 38 is arranged at one end of the inner side of the sliding groove 39 close to the winding wheel 35. The end of the traction rope 36 far from the winding wheel 35 passes through the stop baffle 38 and is fixedly connected with the end of the locking pin 31. A third elastic member 37 is arranged between the stop baffle 38 and the locking pin 31. The third elastic member 37 is preferably a spring;

[0040] As Figures 1 - 3 , Figure 5 shown, in order to closely fit the support top plate 2 with the bottom board of the post-cast strip after the vertical rod 1 is erected, a fine adjustment component is provided at the lower end of the vertical rod 1. The fine adjustment component includes a sleeve 17 rotatably arranged at the bottom of the vertical rod 1. A fine adjustment screw rod 7 corresponding to the vertical rod 1 and threadedly connected with the inner wall of the sleeve 17 is fixedly arranged at the top of the fixed base 3. A second driving component for driving the rotation of the sleeve 17 is arranged at the lower end of the vertical rod 1. The second driving component includes a fixed housing 8 fixedly arranged on the side wall of the lower end of the vertical rod 1. A second gear 20 is rotatably arranged in the middle of the inner side of the fixed housing 8. A first hand wheel 19 for driving the rotation of the second gear 20 is arranged at the upper end of the fixed housing 8. A first gear 18 meshing with the second gear 20 is fixedly arranged on the outer side of the sleeve 17.

[0041] As Figures 1 - 3 , Figures 5 - 8As shown in the figure, in order to reduce the pressure damage to the thread between the fine-tuning screw 7 and the sleeve 17 during use, a clamping component for clamping the fine-tuning screw 7 and linked with the locking pin 31 is arranged inside the vertical rod 1. The clamping component includes an inner rod 21 vertically and movably arranged inside the vertical rod 1. The upper end of the inner rod 21 is located inside the adjusting inner rod 6 and is movably connected with the adjusting inner rod 6. A jack 22 corresponding to the through hole 16 is arranged on the side wall of the upper end of the inner rod 21. One end of the locking pin 31 far from the first driving component passes through the through hole 16, the adjusting hole 14 and is inserted and matched with the jack 22. The longitudinal height inside the through hole 16 is greater than the longitudinal thickness of the locking pin 31, which is convenient for the locking pin 31 to press the inner rod 21 downward. A driving column 25 is vertically and movably arranged inside the lower end of the vertical rod 1. A clamping rod 12 located below the driving column 25 is arranged at the top of the fine-tuning screw 7. A U-shaped clamping arm 10 is radially movably arranged along the side wall of the lower end of the vertical rod 1. In order to directly improve the stability of the clamping arm 10, a first guide rod 27 corresponding to the clamping arm 10 is arranged on the side wall of the vertical rod 1. The clamping arm 10 is movably and guidingly connected to the outside of the first guide rod 27. An inclined guide groove 28 is arranged on the side wall of the upper end of the clamping arm 10, and the upper end of the clamping arm 10 extends to the inside of the vertical rod 1 and corresponds to the driving column 25. A groove 29 corresponding to the upper end of the clamping arm 10 is arranged on the side wall of the driving column 25. A guide wheel 30 movably and guidingly connected to the guide groove 28 is arranged inside the groove 29. When the guide wheel 30 has a tendency to move downward, the clamping arm 10 will have a tendency to move toward the axis direction of the vertical rod 1. The lower end of the clamping arm 10 extends to the inside of the vertical rod 1 and corresponds to the clamping rod 12.

[0042] Furthermore, as Figure 4 , Figure 9 , Figure 10 shown, in order to make the locking pin 31 have a tendency to move downward, a bracket 15 located below the locking frame 9 is fixedly arranged between multiple vertical rods 1. A second elastic member 34 is arranged between the bracket 15 and the locking frame 9. In order to improve the 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 penetrates through the bracket 15 and is movably and guidingly matched with the bracket 15. The second elastic member 34 is preferably a spring, and the spring is sleeved outside the second guide rod 33.

[0043] As Figures 6 - 7 shown, in order to ensure the support for the inner rod 21 before pouring the post-cast strip, a first convex ring 24 is arranged on the outer wall of the lower end of the inner rod 21. A second convex ring 26 located below the first convex ring 24 is fixedly arranged on the inner wall of the vertical rod 1. A first elastic member 23 is arranged between the first convex ring 24 and the second convex ring 26. The first elastic member 23 is preferably a spring. The inner rod 21 can be supported by the first elastic member 23 to avoid the clamping arm 10 clamping the fine-tuning screw 7 before pouring and prevent fine-tuning from being impossible.

[0044] In addition, asFigure 4 As shown, in order to facilitate the disassembly and assembly of the support top plate 2, a quick-release sleeve 13 corresponding to the adjusting inner rod 6 is provided at the bottom of the support 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.

[0045] As Figures 1 - 2 , Figure 4 shown, in order to increase the stability between the fine-adjustment screw rod 7 and the fixed base 3 and between the quick-release sleeve 13 and the support top plate 2, stiffening plates 11 are fixedly welded between the side wall of the quick-release sleeve 13 and the bottom wall of the support top plate 2 and between the side wall of the lower end of the fine-adjustment screw rod 7 and the bottom wall of the fixed base 3. The stiffening plates 11 are preferably triangular.

[0046] This application also includes an adjustable building engineering load post-cast strip support method, which is implemented by the above-mentioned adjustable building engineering load post-cast strip support device, and includes the following steps:

[0047] Step 1: Set a wooden board at the bottom of the post-cast strip to block the post-cast strip area, measure the distance between the wooden board and the lower concrete structural layer, and adjust the approximate position of the support top plate 2 through the coarse-adjustment component according to the measured distance;

[0048] Step 2: Set up the vertical rod 1, make the fixed base 3 fit on the lower concrete structural layer, and align the support top plate 2 with the support wooden board at the bottom of the post-cast strip;

[0049] Step 3: Adjust the support top plate 2 to closely adhere to the bottom of the wooden board through the fine-adjustment component.

[0050] Working principle: When in use, a wooden board is attached to the bottom of the post-cast strip to block the post-cast strip area. For subsequent pouring, measure the distance between the wooden board and the concrete structure layer below. Adjust the position of the support top plate 2 according to the measured distance and through the coarse adjustment component. Specifically, turn the second handwheel 32 to drive the winding wheel 35 to rotate. The winding wheel 35 winds the traction rope 36. The traction rope 36 pulls the displacement of the locking pin 31. At the same time, the third elastic member 37 is compressed, and the end of the third elastic member 37 disengages from the corresponding jack 22 and adjustment hole 14. Then push and pull the support top plate 2 to drive the adjustment inner rod 6 to displace in the vertical rod 1. After the position is appropriate, make one of the adjustment holes 14 closest to the through hole 16 coincide with the through hole 16. Then loosen the second handwheel 32, and the second elastic member 34 resets. The locking pin 31 is pushed into the corresponding adjustment hole 14. And because the jack 22 corresponds to the through hole 16, the end of the locking pin 31 enters the jack 22. At this time, the adjustment inner rod 6 is locked. Then place the entire vertical rod 1 vertically below the wooden board, with the fixed base 3 attached to the concrete structure layer below. The support top plate 2 is aligned with the wooden board. At this time, due to the support of the first elastic member 23, the inner rod 21 will not apply pressure to the driving column 25. Furthermore, the lower end of the clamping arm 10 will not clamp the clamping rod 12. Then rotate the first handwheel 19 to drive the second gear 20 to rotate. The second gear 20 drives a plurality of sleeves 17 to rotate through the first gear 18. Furthermore, the fine adjustment screw rod 7 drives the vertical rod 1 to rise until the support top plate 2 fits against the bottom of the wooden board. At this time, the support is completed. Pour the post-cast strip on the top of the wooden board. Therefore, the support top plate 2 gradually bears the pressure of the concrete. The support top plate 2 drives the adjustment inner rod 6 to press down. Since the longitudinal height inside 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. Therefore, the adjustment inner rod 6 can drive the inner rod 21 to have a downward pressing trend through the locking pin 31. Furthermore, the inner rod 21 continues to compress the first elastic member 23 and apply pressure to the driving column 25. The driving column 25 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 displace towards the axis direction of the vertical rod 1. Furthermore, the lower end of the clamping arm 10 clamps the outside of the clamping rod 12. And the greater the pressure received by the support top plate 2, the greater the pressure applied by the clamping arm 10 to the clamping rod 12. It can reduce the pressure of the thread between the fine adjustment screw rod 7 and the sleeve 17, improve the service life, and facilitate subsequent recycling. Using the gravity of the poured concrete as the driving force, the structure is compact and ingenious. At the same time, with the reasonable configuration of the coarse adjustment component and the fine adjustment component, it not only realizes stable support, but also can be used as an independent back support to replace the traditional formwork erection, greatly increasing the construction efficiency and saving the material turnover cost. And it also greatly improves the usable space in the building, facilitates personnel passage and subsequent construction, can also adapt to different support heights, and is convenient to disassemble and assemble.

[0051] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention as claimed.
