Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, and more specifically, to a device for underwater concrete pouring. Background Technique

[0002] Underwater concrete pouring refers to the construction and pouring of concrete in water or underwater. Due to its advantages such as high bearing capacity, good stability, small settlement, and little influence by the construction water level or the position water level, the cast-in-place concrete pile foundation has become one of the most commonly used foundation types in buildings at home and abroad. The control of the existing concrete pouring depth is carried out by construction workers through the sounding hammer method by feeling, which is usually affected by various factors such as construction experience, on-site concrete quality, and the weight of the sounding hammer, resulting in the situation that it is not easy to judge the exact height of the concrete.

[0003] Regarding the above problems, for the technical problem that it is not easy to judge the exact height of the concrete in the existing concrete pouring operation, after a large number of retrievals, a positioning pouring device for underwater concrete with the patent number CN214245732U is found. It includes a formwork, and an induction block is slidably connected to the side wall of the formwork. The induction block is located above the water surface, and the induction block is fixedly connected to a support plate. A connecting member is provided between the induction block and the support plate. A sliding groove for the sliding connection of the connecting member is opened on the side wall of the formwork. The support plate is located inside the formwork. The positioning pouring device for underwater concrete further includes a limiting member for restricting the sliding of the induction block. This application has the effect that it is easier to judge the height of underwater concrete pouring. However, the technical solution provided by this patent has the following problems:

[0004] (1) The measurement-related structure needs to be installed inside the formwork. The support plate and its connection structure slide on the inner wall of the formwork, and a sliding groove is opened on the side wall of the formwork, so that the concrete will flow into it after pouring, which may cause leakage of the formwork seal, resulting in waste and inconvenience.

[0005] (2) After the concrete is poured, due to the lack of a leveling structure, the concrete inside the formwork may be locally too high or too low, making it less regular after pouring.

[0006] The utility model can limit the poured concrete to prevent over-pouring, and can level the concrete, making it more regular after pouring. Content of the Utility Model

[0007] The purpose of the utility model is to solve the technical problems proposed in the above background technique, and provide a device for underwater concrete pouring. The pouring height can be controlled by a limit measurement mechanism during concrete pouring through the cooperation of the limit measurement mechanism; the concrete leveling mechanism can apply pressure to the concrete surface to achieve a leveling effect.

[0008] To achieve the above object, the utility model provides the following technical solutions: A device for underwater concrete pouring, comprising: a formwork, a floating plate is arranged in the middle of the interior of the formwork, limit measurement mechanisms are arranged at both the left and right ends of the top of the formwork, drums are fixedly installed at both the left and right ends of the formwork, and a concrete leveling mechanism is arranged inside the drums.

[0009] Further preferred solution: The limit measurement mechanism includes: a connecting rod, a sliding sleeve, a screw rod and a threaded sleeve;

[0010] Sliding sleeves are connected to both the left and right ends of the top of the floating plate through connecting rods, two screw rods are provided and are respectively fixedly installed at both the left and right ends of the top of the formwork, and two threaded sleeves are provided and are respectively sleeved on the upper ends of the two screw rods.

[0011] Further preferred solution: The concrete leveling mechanism includes: a roller, a pulling rope, a turning handle and a hook;

[0013] Further preferred solution: The connecting rod is arranged in an L shape, and both ends of the connecting rod are fixedly installed with the floating plate and the sliding sleeve respectively.

[0014] Further preferred solution: The sliding sleeve is slidably connected to the outer surface of the screw rod, and a size line is printed on the outer surface of the screw rod.

[0015] Further preferred solution: Threads matching the outer surface of the screw rod are arranged around the inside of the threaded sleeve, and the threaded sleeve is located above the sliding sleeve.

[0016] Further preferred solution: The diameter of the floating plate matches the inner diameter of the formwork, and the periphery of the floating plate is slidably attached to the inner periphery of the inner wall of the formwork.

[0017] Beneficial effects:

[0018] 1. By arranging the floating plate and the limit measurement mechanism, through the design of the limit measurement mechanism, the position of the threaded sleeve can be adjusted in advance to determine the maximum height after concrete pouring; when the floating plate is jacked up, the connecting rod drives the sliding sleeve to move upward along the screw rod, and when the sliding sleeve moves to the preset position of the threaded sleeve and is limited by the threaded sleeve, it means that the concrete pouring has reached the designed height, thus controlling the pouring height; and when the concrete is poured and limited, there will be no concrete leakage, making the poured concrete column more regular;

[0019] 2. By setting up a concrete leveling mechanism, the force of the pulling rope is transmitted to the sliding sleeve through the linkage of the winding roller and the hook, thereby affecting the position of the floating plate, and then exerting pressure on the concrete surface to achieve a flat and uniform effect.

[0020] 3. In summary, for the device used for underwater concrete pouring, the floating plate and the limit measurement mechanism cooperate to pre-adjust the position of the threaded sleeve, determine the maximum height after concrete pouring, and control the pouring height through the limit measurement mechanism during concrete pouring; the concrete leveling mechanism can exert pressure on the concrete surface to achieve a flat effect, ensuring the stability and uniformity of the concrete structure.

When the sliding sleeve 4 moves to the preset position of the threaded sleeve 6, the threaded sleeve 6 will prevent it from continuing to move upward, indicating that the concrete pouring is completed;

[0029] , in the embodiment of the present utility model, the concrete leveling mechanism includes: a winding roller 8, a pulling rope 9, a turning handle 10 and a hook 11; The winding roller 8 is rotatably arranged inside the winding drum 7 so that the winding roller 8 can freely rotate inside the winding drum 7; One end of the pulling rope 9 is fixed on the winding roller 8, and the remaining part is wound on the outer surface of the winding roller 8. The end far from the winding roller 8 penetrates to the top of the winding drum 7 and is sleeved inside the hook 11, so that the pulling rope 9 can be retracted and released under the rotation of the winding roller 8; The turning handle 10 is fixedly installed at the front end of the winding roller 8 and can control the winding roller 8 by rotation; The hook 11 is fixedly installed on the outside of the sliding sleeve 4 and is connected to the pulling rope 9. It can move under the action of the retracted pulling rope 9, driving the connected sliding sleeve 4 downward, and then pressing the floating plate 2 against the concrete surface to achieve the effect of leveling and uniform treatment.

[0030] , in the embodiment of the present utility model, the connecting rod 3 is arranged in an L shape, and the two ends of the connecting rod 3 are fixedly installed with the floating plate 2 and the sliding sleeve 4 respectively, making the connection between the floating plate 2 and the sliding sleeve 4 more stable, which can reduce loosening or deformation caused by other external forces during use and ensure stability.

[0031] In the embodiment of the present utility model, the sliding sleeve 4 is slidably connected to the outer surface of the screw rod 5, and dimension lines are printed on the outer surface of the screw rod 5.

When moving, refer to the dimension lines on the surface of the screw rod 5, so that the distance after adjusting the threaded sleeve 6 is the maximum height after subsequent concrete pouring; then, after pouring the concrete into the formwork 1, the concrete liquid level can lift the floating plate 2, so that the connecting rod 3 drives the sliding sleeve 4 to move upward along the screw rod 5. When the sliding sleeve 4 moves upward to the limit, it will be limited by the preset threaded sleeve 6, indicating that the concrete pouring is completed. The restriction by the floating plate 2 can prevent excessive concrete pouring; finally, after the concrete is poured, the turning handle 10 can be rotated to make the winding drum 7 wind up the pulling rope 9, so as to pull the hook 11 and the connected sliding sleeve 4 downward, and then make the floating plate 2 squeeze downward, realizing the flatness and uniformity of the concrete surface; when maintenance is required, the pulling rope 9 sleeved on the hook 11 can be removed; then the threaded sleeve 6 is screwed upward along the screw rod 5; then the sliding sleeve 4, the connecting rod 3 and the floating plate 2 can be pulled upward for removal, so as to facilitate regular maintenance, and the operation is convenient.
