Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically a rapid formwork erection device for large cantilever cap beams under side traffic conditions. Background Technology

[0002] Currently, with the rapid development of my country's transportation infrastructure engineering technology, the overall construction level of bridge engineering has been greatly improved. In the construction of mainstream bridges, especially the construction of cap beams, the construction method of on-site concrete pouring is mainly adopted. In some special cases, the construction method of integral precast concrete cap beams and hoisting them into place is also adopted.

[0003] A cap beam is a horizontal beam installed on top of a bridge pier to support, distribute, and transfer the load of the superstructure. It is also called a cap beam. It is a reinforced concrete or lightly reinforced concrete beam installed on the pier or on the bridge piles. Its main function is to support the superstructure of the bridge and transfer all the load to the substructure. Some cap beams are directly connected to the bridge piles, while others are connected to the columns first and then to the cap beam.

[0004] However, existing equipment is inconvenient and difficult to fix templates of different sizes, which reduces installation efficiency. It cannot achieve multi-angle support and real-time calibration of the template level, and the template may be slightly offset. The equipment has a limited range of applications, is inconvenient to adjust, and cannot be easily and quickly fixed, which reduces the stability of the template. It cannot be flexibly applied and reused during fixing, which may cause injury to workers and the construction site. It cannot assist in vibrating concrete, and it is inconvenient to cover the poured concrete, which may cause the membrane to be blown away. Therefore, we propose a new device to solve the above problems. Utility Model Content

[0009] Optionally, the fixing assembly includes a fixing base, a fixing shaft, a fixing hydraulic rod, a docking shaft, and a fixing plate. The fixing shaft is inserted into the interior of the fixing base, the fixing hydraulic rod is rotatably connected to the outer surface of the fixing shaft, the docking shaft is inserted into the interior of the fixing hydraulic rod, and the fixing plate is rotatably connected to the outer surface of the docking shaft.

[0010] Optionally, a shock-absorbing pad is provided on one side of the fixing seat, and a fixing bolt is threaded through the upper surface of the fixing plate, and the number of fixing bolts is two.

[0011] Optionally, the adjusting assembly includes an adjusting hydraulic rod, an adjusting seat, an adjusting shaft, and an adjusting plate. The adjusting seat is inserted into the lower surface of the adjusting hydraulic rod, the adjusting shaft is inserted into the interior of the adjusting seat, the adjusting plate is rotatably connected to the outer surface of the adjusting shaft, and two adjusting bolts are threaded through the upper surface of the adjusting plate.

[0012] Optionally, the cover assembly includes a bearing, a cover shaft, a film, and a limiting rod. The cover shaft is rotatably connected inside the bearing, the outer surface of the cover shaft is provided with a film, and the limiting rod is inserted inside the bearing.

[0014] Optionally, the upper surface of the top plate is threaded with fastening bolts, and the top plate is threaded with a cover assembly through the fastening bolts.

[0015] Optionally, a toothed rack is inserted into one side of the upper side plate, and the moving gear meshes with the toothed rack. A toothed rack is inserted into the lower surface of the upper side plate, and the adjusting gear meshes with the toothed rack.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model has a reasonable structure. A moving motor inside the top plate drives a moving gear to rotate, causing the upper and lower side plates to move a suitable distance within the top and bottom plates. An adjusting motor inside the lower side plate drives an adjusting gear to rotate, causing the upper side plate to move a suitable distance within the lower side plate. Workers place the template into the equipment, and a moving bolt moves a moving plate within the top plate. After moving to the appropriate distance, tightening the moving bolt fixes the template in place. This achieves convenient and quick fixing of templates of different sizes, more easily adapting to different template dimensions, saving manpower and resources, improving installation efficiency, and reducing the inconvenience of fixing the template during installation, preventing slight template misalignment and potential template displacement. It also reduces the limited applicability of the equipment. An adjusting plate is rotated within an adjusting seat, allowing the adjusting bolt to fix the adjusting plate on a flat surface. Workers observe a level to determine if the template is level. If the template is not level... At that time, the two adjustable hydraulic rods on the left and right sides are used to move and adjust the formwork up and down, so that the formwork fits more tightly during construction and pouring. This prevents unevenness of the pouring surface caused by uneven formwork. It also enables multi-angle support and real-time calibration of the formwork level, thereby reducing unevenness of the pouring surface, construction interruptions caused by uneven formwork, and potential dangers during pouring. After adjusting the equipment, the fixed hydraulic rod is rotated out through the fixed shaft. After adjusting the angle of the fixed hydraulic rod, the fixed plate is rotated to the appropriate angle through the docking shaft, so that the fixing bolts can fix the fixing plate to the plane. This achieves convenient and quick fixation of the equipment. Combined with shock-absorbing pads and bolt locking, it can adapt to the vibration load under traffic conditions, improve the stability of the formwork, and prevent the formwork from deforming. The fixing components are more flexible and can be repeatedly adjusted to the appropriate position for fixation, thereby reducing the risk of the formwork bursting under pressure during pouring, which could cause injury to workers and the construction site and increase the difficulty of the work.

[0018] 2. In this utility model, a vibrator is placed on a vibrating base for vibration. The vibration is transmitted to the upper steel plate through the vibrating base, and then to the lower steel plate through a telescopic rod. The vibration force of the vibrating base is transmitted synchronously. The telescopic rod can move with the upper side plate. By vibrating, the concrete inside the formwork is assisted in vibrating, expelling air bubbles from the concrete. This helps workers remove air bubbles from the concrete inside the formwork, improving the density and strength of the concrete, reducing the presence of air bubbles during concrete pouring, and improving construction quality. After the concrete is poured, the worker pulls out the limiting rod, and the covering shaft inside the bearing seat rotates, allowing the worker to pull the film to move and cover it. The covering shaft locks the unfolded length of the film, making the operation of covering the film simpler and more convenient. It also keeps the film warm and moist, preventing it from rolling on its own, thus reducing the need for the film to be blown away and re-covered. Attached Figure Description

[0030] As a preferred embodiment of this example, Figures 2 to 7As shown, a movable bolt 2 is threaded through the upper surface of the top plate 1, and a movable piece 3 is threaded through the top plate 1 via the movable bolt 2. A movable motor 4 is inserted inside the top plate 1, and a movable gear 5 is sleeved on one end of the movable motor 4. An upper side plate 6 is inserted inside the top plate 1, and a gear rack is inserted on one side of the upper side plate 6. The movable gear 5 meshes with the gear rack. A lower side plate 9 is sleeved on the lower part of the upper side plate 6, and an adjusting motor 10 is inserted inside the lower side plate 9. An adjusting gear 11 is sleeved on one end of the adjusting motor 10. A gear rack is inserted on the lower surface of the upper side plate 6, and the adjusting gear 11 meshes with the gear rack. A fixing component 14 is inserted on one side of the lower side plate 9. The fixing component 14 includes a fixing seat 401, a fixing shaft 402, a fixing hydraulic rod 403, a docking shaft 404, and a fixing... A damping pad is provided on one side of the fixed plate 405 and the fixed seat 401. A fixed rotating shaft 402 is inserted into the fixed seat 401. A fixed hydraulic rod 403 is rotatably connected to the outer surface of the fixed rotating shaft 402. A docking rotating shaft 404 is inserted into the fixed hydraulic rod 403. A fixed plate 405 is rotatably connected to the outer surface of the docking rotating shaft 404. Two fixing bolts are threaded through the upper surface of the fixed plate 405. A base plate 15 is sleeved on one side of the lower side plate 9. A level 16 is inserted into the upper surface of the base plate 15. An adjusting assembly 17 is inserted into the lower surface of the base plate 15. The adjusting assembly 17 includes an adjusting hydraulic rod 701, an adjusting seat 702, an adjusting rotating shaft 703, and an adjusting plate 704. An adjusting seat 704 is inserted into the lower surface of the adjusting hydraulic rod 701. 2. An adjusting shaft 703 is inserted into the interior of the adjusting seat 702. An adjusting plate 704 is rotatably connected to the outer surface of the adjusting shaft 703. An adjusting bolt is threaded through the upper surface of the adjusting plate 704. There are two adjusting bolts. During use, the moving motor 4 in the top plate 1 drives the moving gear 5 to rotate, causing the upper side plate 6 and the lower side plate 9 on both sides to move a suitable distance within the top plate 1 and the bottom plate 15. The adjusting motor 10 in the lower side plate 9 drives the adjusting gear 11 to rotate, causing the upper side plate 6 to move a suitable distance within the lower side plate 9. The operator puts the template into the equipment, and the moving bolt 2 moves the moving piece 3 within the top plate 1. After moving to the appropriate distance, the moving bolt 2 is tightened to move the moving piece 3 to adjust the template. The fixed design allows for convenient and quick fixing of templates of different sizes, making it more adaptable to various template dimensions. This saves manpower and resources, improves installation efficiency, and reduces the risk of template misalignment or displacement during installation. It also reduces the limited applicability of the equipment. Adjustment is achieved by rotating the adjusting plate 704 within the adjusting seat 702, allowing the adjusting bolts to fix the adjusting plate 704 on a flat surface. Workers can then observe the level 16 to determine if the template is level. If not, the two adjusting hydraulic rods 701 can be moved up and down for adjustment. This ensures a tighter fit during pouring, preventing unevenness in the poured surface caused by template unevenness.This system enables multi-angle support and real-time calibration of the formwork level, reducing unevenness of the pouring surface, minimizing construction interruptions caused by formwork unevenness, and reducing potential dangers during pouring. After adjusting the equipment, the fixed hydraulic rod 403 is rotated out via the fixed pivot 402. After adjusting the angle of the fixed hydraulic rod 403, the fixed plate 405 is rotated to a suitable angle via the docking pivot 404, allowing the fixing bolts to fix the fixed plate 405 to the plane. This achieves convenient and quick equipment fixation. Combined with shock-absorbing pads and bolt locking, it adapts to vibration loads under traffic conditions, improving formwork stability and preventing formwork deformation. Fixing via the fixing component 14 is more flexible, allowing for repeated adjustments to the appropriate position for fixation, thus reducing the risk of the formwork bursting under pressure during pouring, which could cause injury to workers and the construction site, and increase the difficulty of the work.

[0031] like Figures 2 to 4 and Figure 8 As shown, in this embodiment, a vibration base 7 is inserted into the upper surface of the upper side plate 6, an upper steel plate 8 is inserted into one side of the upper side plate 6, a lower steel plate 12 is inserted into one side of the lower side plate 9, a telescopic rod 13 is inserted into the interior of the lower steel plate 12, a cover assembly 18 is inserted into the upper surface of the top plate 1, a fastening bolt is threaded through the upper surface of the top plate 1, and the cover assembly 18 is threaded through the top plate 1 by the fastening bolt. The cover assembly 18 includes a shaft seat 801, a cover shaft 802, and a diaphragm. 803 and a limiting rod 804 are connected to the inner part of the bearing seat 801, and a covering shaft 802 is rotatably connected thereto. A thin film 803 is provided on the outer surface of the covering shaft 802. A limiting rod 804 is inserted into the inner part of the bearing seat 801. A hole is opened on the upper surface of the bearing seat 801 and a hole is opened on the upper surface of the covering shaft 802. The limiting rod 804 passes through the hole to limit the covering shaft 802. During use, the vibrator is placed on the vibrating base 7 for vibration. The vibration of the vibrating base 7 is transmitted to the upper steel plate 8, and then to the lower steel plate 12 through the telescopic rod 13. The vibration force of the vibrating base 7 is transmitted synchronously. The telescopic rod 13 can move with the upper side plate 6. By vibrating, it assists in the vibration of the concrete in the formwork, shaking out air bubbles in the concrete. This helps the workers to shake out air bubbles in the concrete in the formwork, improving the tightness and strength of the concrete, reducing the presence of air bubbles in the concrete during pouring, and improving the construction quality. After the concrete is poured, the workers pull out the limiting rod 804, which rotates through the covering shaft 802 in the bearing 801. This allows the workers to pull the film 803 to move and cover the concrete. The covering shaft 802 locks the unfolded length of the film 803, making the operation of covering the film 803 simpler and more convenient. It also keeps the film warm and moist, preventing the film 803 from rolling on its own, thus reducing the need for the film 803 to be blown away and needing to be re-covered.

[0032] The working principle of this practical application is as follows:

[0033] During use, the moving motor 4 inside the top plate 1 drives the moving gear 5 to rotate, causing the upper side plate 6 and lower side plate 9 on both sides to move synchronously to a suitable distance within the top plate 1 and bottom plate 15. The adjusting motor 10 inside the lower side plate 9 drives the adjusting gear 11 to rotate, adjusting the upper side plate 6 to a suitable height within the lower side plate 9. The operator places the template into the equipment, and the moving bolt 2 moves the moving piece 3 within the top plate 1. After moving to the appropriate distance, the moving bolt 2 is tightened to fix the moving piece 3 to the template. The adjusting plate 704 is rotated within the adjusting seat 702 to adjust the adjusting bolt, which then fixes the adjusting plate 704 to the plane. The operator observes the level 16 to determine if the template is level. If the template is not level, the two adjusting hydraulic rods 701 on the left and right are used to move it up and down for adjustment. After the equipment is adjusted, it is fixed... The fixed rotating shaft 402 rotates the fixed hydraulic rod 403 out. After adjusting the angle of the fixed hydraulic rod 403, the fixed plate 405 is rotated to a suitable angle through the docking rotating shaft 404, so that the fixing bolt can fix the fixed plate 405 on the plane. When pouring concrete, the vibrator is placed on the vibrating base 7 to vibrate. The vibration is transmitted to the upper steel plate 8 through the vibrating base 7, and the vibration of the upper steel plate 8 is transmitted to the lower steel plate 12 through the telescopic rod 13, synchronously transmitting the vibration force of the vibrating base 7. The telescopic rod 13 can move with the upper side plate 6. The vibration is used to assist the vibration of the concrete in the formwork, and the air bubbles in the concrete are shaken out. After the concrete is poured, the worker pulls out the limiting rod 804 and rotates it through the covering rotating shaft 802 in the shaft seat 801, so that the worker pulls the film 803 to move and cover it. The unfolded length of the film 803 is locked by the covering rotating shaft 802.

[0034] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
