Description

Technical Field

[0001] This application relates to the technical field of post-cast strip supports, for example, it relates to an adjustable post-cast strip support device. Background Art

[0002] A post-cast strip is a concrete strip reserved in structures such as beams and slabs with a certain width and poured after a certain period of time to prevent harmful cracks in the cast-in-place reinforced concrete structure due to uneven shrinkage or settlement. The traditional post-cast strip support system construction uses a steel pipe scaffold system, and it must be sealed at the top of the structure for more than two months to achieve complete closure.

[0003] For the traditional steel pipe scaffold support technology, the removal of materials such as steel pipes is relatively troublesome, and it is difficult to erect for different height scenarios. Limited by the length of the steel pipes, it is not convenient to apply to working environments with different elevations, and its practicability has limitations. Summary of the Utility Model

[0004] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. The summary is not a general review, nor is it intended to identify key / important constituent elements or delineate the protection scope of these embodiments, but rather serves as a preface to the subsequent detailed description.

[0005] The embodiments of the present disclosure provide an adjustable post-cast strip support device, which is convenient for adapting to working scenarios with different elevations and has high practicability.

[0006] To achieve the above object, the technical solution adopted by the present utility model is:

[0007] An adjustable post-cast strip support device includes main support columns and fixing components. There are multiple groups of main support columns, and fixing components are arranged between adjacent main support columns. A top formwork erected at the position of the post-cast strip is arranged on the top of the main support columns, and the main support columns support the top formwork. The main support column mainly consists of a lifting cylinder, a bottom column, a threaded column, a top disc, and a fixing plate. A top disc is rotatably arranged at the top end of the lifting cylinder, and the top disc directly abuts against the bottom side of the top formwork. Multiple groups cooperate to support and fix the top formwork. The inside of the lifting cylinder is hollow and threadedly sleeved with a threaded column. The bottom end of the threaded column is fixedly connected to the top end of the bottom column. By rotating the lifting column in cooperation with the threaded column, the distance from the bottom column can be changed, and thus the height of the lifting column can be increased, which can facilitate the height adjustment of the main support column to adapt to scenarios with different elevations. The bottom end of the bottom column is fixedly connected with a fixing plate, and the fixing plate supports the bottom column. The fixing component includes a hollow screw sleeve rod, a screw rod, and a clamping frame. Both ends of the hollow screw sleeve rod are threadedly sleeved with screw rods. One end of the screw rod is threadedly connected to the hollow screw sleeve rod, and the other end is rotatably connected to a clamping frame. By rotating the screw rods at both ends of the hollow screw sleeve rod, the overall length of the screw rod and the hollow screw sleeve rod will be increased or decreased, which is convenient for adapting to different distance scenarios between the main support columns, so as to increase the practicality. The clamping frame clamps the corresponding lifting cylinder, and the clamping frame, in cooperation with the screw rod and the hollow screw sleeve rod, realizes the fixation of the distance between adjacent lifting cylinders, preventing the main support column from shifting during work and increasing the stability of the support for the top formwork. This device can be applied to scenarios with different elevations through the cooperation of the lifting column and the threaded column. At the same time, the stability between the main support columns is increased by setting fixing components between adjacent main support columns, ensuring the safe support of the post-cast strip top formwork and further increasing the practicality.

[0008] Furthermore, a number of fine-tuning screw rods are evenly arranged along the circumference of the bottom column on the fixing plate. The fine-tuning screw rods threadedly penetrate the fixing plate. A bottom cushion plate is arranged on the bottom side of the fixing plate. By laying the bottom cushion plate on the floor and then screwing down the fine-tuning screw rods, the fine-tuning screw rods will abut against the bottom cushion plate. Continuing to screw down will drive the fixing plate to move upward, so as to achieve the purpose of finely adjusting the overall height of the main support column, which can adjust the pressure exerted by the lifting cylinder driving the top disc on the top formwork, ensure that the pressure is sufficient and there will be no grout leakage phenomenon, and at the same time achieve the purpose of finely adjusting the height, further increasing the practicality of this device.

[0009] Furthermore, a lever is fixedly arranged on the outer side of the bottom end of the lifting cylinder, and the operator can conveniently rotate the lifting cylinder through the lever.

[0010] Further, reserved holes are provided in the top plate corresponding to the positions of the fine adjustment screws in the fixed plate. The multi-section combination of the main support columns can be achieved through the cooperation of the reserved holes and the fine adjustment screws. When the elevation of the construction site is too high, the height of a single main support column is far from enough, so multi-section combination is required to increase the height. When one main support column presses its top plate against the bottom side of the fixed plate in another group of main support columns, and then is fixed by threading and connecting a fine adjustment nut, the combination of two groups of main support columns can be realized, so as to adapt to more elevation scenarios during assembly. Fixed nuts are sleeved at the bottom ends of the fine adjustment screws. After the fine adjustment screws are adjusted, the fixed nuts can be tightened to effectively prevent the fine adjustment screws from loosening.

[0011] Further, side plates are integrally formed on both sides of the clamping frame. The distance between the side plates in the same group of clamping frames is greater than the diameter of the lifting cylinder, so that the clamping frame can easily catch the lifting column, realize the fixation of the distance between two adjacent main support columns, and prevent deviation.

[0012] Further, top fixing screws are provided on both sides of the clamping frame. The top fixing screws are respectively threaded through the corresponding side plates, and one end of the top fixing screw abuts against the side wall of the lifting cylinder. The top fixing screws on both sides of the same clamping plate cooperate to completely fasten the clamped lifting cylinder, further increasing the stability and preventing the lifting cylinder from rotating.

[0013] Further, an inner arc is formed inside the clamping frame. The arc shape of the inner arc is adapted to the circumference of the lifting cylinder, so as to achieve the tightness of the clamping frame to the lifting cylinder, further reducing the risk of the lifting cylinder deviating and increasing the stability.

[0014] Further, knobs are fixedly provided at the ends of the top fixing screws located outside the clamping frame, which is convenient for operators to rotate the top fixing screws through the knobs to fix the abutment of the lifting column.

[0015] The adjustable post-cast strip support device provided by the embodiment of the present disclosure can achieve the following technical effects:

[0016] 1. The inside of the lifting cylinder in this device is hollow and threadedly sleeved with a threaded column. The bottom end of the threaded column is fixedly connected to the top end of the bottom column. By rotating the lifting column in cooperation with the threaded column, the distance from the bottom column can be changed, and thus the height of the lifting column can be increased, so as to facilitate the height adjustment of the main support column and adapt to different elevation scenarios.

[0017] 2. By rotating the screws at both ends of the hollow sleeve rod in this device, the overall length of the screw and the hollow sleeve rod can be increased or decreased, so as to facilitate adapting to different distance scenarios between the main support columns, increasing the practicability. The clamping frame clamps the corresponding lifting cylinder, and the clamping frame cooperates with the screw and the hollow sleeve rod to fix the distance between adjacent lifting cylinders, preventing the main support column from deviating during work and increasing the stability of the support for the top formwork.

Detailed Description of the Embodiments

[0025] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure will be described in detail below in conjunction with the drawings. The attached drawings are only for reference and explanation, and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of explanation, multiple details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be shown in a simplified manner to simplify the drawings.

[0026] An adjustable post-cast strip support device includes main support columns 1 and fixing components 2. There are multiple groups of the main support columns 1, and fixing components 2 are arranged between adjacent main support columns 1. A top formwork 4 erected at the position of the post-cast strip is provided at the top of the main support columns 1, and the main support columns 1 support the top formwork 4. The main support columns 1 are mainly composed of a lifting cylinder 11, a bottom column 12, a threaded column 13, a top plate 14, and a fixing plate 15. A top plate 14 is rotatably provided at the top end of the lifting cylinder 11, and the top plate 14 directly abuts against the bottom side of the top formwork 4. Multiple groups cooperate to support and fix the top formwork 4. The inside of the lifting cylinder 11 is hollow and threadedly sleeved with the threaded column 13. The bottom end of the threaded column 13 is fixedly connected to the top end of the bottom column 12. By rotating the lifting column in cooperation with the threaded column 13, the distance from the bottom column 12 can be changed, and thus the height of the lifting column can be increased, which can facilitate the height adjustment of the main support column 1 to adapt to scenarios with different elevations. The outer side of the bottom end of the lifting cylinder 11 is fixedly provided with a lever 111, and the operator can conveniently rotate the lifting cylinder 11 through the lever 111. The bottom end of the bottom column 12 is fixedly connected with a fixing plate 15, and the bottom column 12 is supported by the fixing plate 15.

[0027] The fixing component 2 includes a hollow sleeve rod 21, a screw rod 22, and a clamping frame 23. Screw rods 22 are threadedly sleeved at both ends of the hollow sleeve rod 21. One end of the screw rod 22 is threadedly connected to the hollow sleeve rod 21, and the other end is rotatably connected to a clamping frame 23. By rotating the screw rods 22 at both ends of the hollow sleeve rod 21, the overall length of the screw rod 22 and the hollow sleeve rod 21 will be increased or decreased, which is convenient for adapting to different distance scenarios between the main support columns 1 to increase the practicality. The clamping frame 23 is clamped to the corresponding lifting cylinder 11. The clamping frame 23, in cooperation with the screw rod 22 and the hollow sleeve rod 21, fixes the distance between adjacent lifting cylinders 11 to prevent the main support column 1 from shifting during work and increase the stability of the support for the top formwork 4. Through the cooperation of the lifting column and the threaded column 13, this device can be applied to adapt to scenarios with different elevations. At the same time, by setting the fixing component 2 between adjacent main support columns 1, the stability between the main support columns 1 is increased to ensure the safe support of the post-cast strip top formwork 4 and further increase the practicality.

[0028] A plurality of fine adjustment screws 16 are uniformly arranged along the circumferential side of the bottom column 12 on the fixed plate 15. The fine adjustment screws 16 are threadedly connected through the fixed plate 15. A bottom cushion plate 3 is arranged on the bottom side of the fixed plate 15. The bottom cushion plate 3 is laid on the floor, and then the fine adjustment screws 16 are screwed downward. The fine adjustment screws 16 will abut against the bottom cushion plate 3. Continuing to screw will drive the fixed plate 15 to move upward, so as to achieve the purpose of finely adjusting the overall height of the main support column 1. The pressure exerted by the lifting cylinder 11 on the top template 4 can be adjusted to ensure that the pressure is sufficient and there will be no slurry leakage phenomenon. At the same time, the purpose of finely adjusting the height is achieved, further increasing the practicability of the device. Reserved holes 141 are arranged at the positions of the fine adjustment screws 16 on the fixed plate 15 corresponding to the top plate 14. The multi-section combination of the main support column 1 can be realized through the cooperation of the reserved holes 141 and the fine adjustment screws 16. When the construction site elevation is too high, the height of a single main support column 1 is far from enough, and multi-section combination is required to increase the height. When one of the main support columns 1 abuts its top plate 14 against the bottom side of the fixed plate 15 in another group of main support columns 1, and then is fixed by threading a fine adjustment nut, the combination of the two groups of main support columns 1 is realized, so as to achieve the assembly and adaptation to more elevation scenarios. Fixed nuts 161 are sleeved at the bottom ends of the fine adjustment screws 16. After the fine adjustment screws 16 are adjusted, the fixed nuts 161 can be tightened, which can effectively prevent the fine adjustment screws 16 from loosening.

[0029] Side plates 231 are integrally formed on both sides of the clamping frame 23. The distance between the side plates 231 in the same group of clamping frames 23 is greater than the diameter of the lifting cylinder 11, so that the clamping frame 23 can easily catch the lifting column, realize the fixation of the distance between two adjacent main support columns 1, and prevent deviation. Top fixing screws 24 are arranged on both sides of the clamping frame 23. The top fixing screws 24 are respectively threadedly connected through the corresponding side plates 231. One end of the top fixing screw 24 abuts against the side wall of the lifting cylinder 11. The top fixing screws 24 on both sides of the same clamping plate cooperate to completely fasten the clamped lifting cylinder 11, further increasing the stability and preventing the lifting cylinder 11 from rotating. Knobs 241 are fixedly arranged at the ends of the top fixing screws 24 located outside the clamping frame 23, which is convenient for operators to rotate the top fixing screws 24 through the knobs 241 to abut and fix the lifting column. An inner arc 232 is formed inside the clamping frame 23. The arc shape of the inner arc 232 is adapted to the circumferential side of the lifting cylinder 11, so as to achieve the tightness of the clamping frame 23 to the lifting cylinder 11, further reducing the risk of the lifting cylinder 11 deviating and increasing the stability.
