Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, and specifically, to a corner structure for installing bridge steel formwork. Background Art

[0002] A bridge generally refers to a structure erected over rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. Steel formwork is a steel formwork used for concrete pouring and molding. In addition to steel formwork, there are also wooden formwork, plywood formwork, etc. Steel formwork is widely used in construction projects due to its characteristics of being used multiple times and having a beautiful concrete pouring and molding. During current bridge construction, sometimes corners need to be formed after pouring. In order to improve the structural strength of the bridge, a corner structure is required when installing steel formwork.

[0003] The existing patent with publication number CN211285286U discloses a corner structure for installing bridge steel formwork, which includes a frame-shaped support. At both ends of the bottom of the frame-shaped support, there are hinged rotating rods. On the rotating rods at both ends of the frame-shaped support, there are hinge seats. On the frame-shaped support, there is a limiting mechanism for limiting the rotating rods. The limiting mechanism includes a telescopic rod fixed to the upper end of the frame-shaped support. The bottom end of the telescopic rod is hinged to the hinge seat. The bottom end of the telescopic rod is fixedly connected with a connecting rod perpendicular to the telescopic rod. On the connecting rod, there is a support plate perpendicular to the connecting rod. The frame-shaped support, the rotating rod and the support plate together form a support for the inner formwork of the bridge. This utility model can be applicable to bridge construction operations with different chamfer angles.

[0004] The following problems exist in the implementation of the above solution. The corner structure of this device can adjust the chamfer angle according to construction needs. When adjusting the angle, it is necessary to drive the rotating rod to rotate by adjusting the length of the telescopic rod. After rotating to the appropriate angle, the telescopic rod can be fixed to limit the rotating rod. However, this telescopic rod is adjusted by longitudinally sliding the sleeve rod in the cavity, and then fixed by tightening the limiting bolt against the sleeve rod, so as to achieve telescopic adjustment. The operation is rather troublesome and cumbersome, greatly reducing the practicability of this device. For this reason, we provide a corner structure for installing bridge steel formwork to solve the above problems. Content of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] As Figure 1 and Figure 2 shown, the present invention provides a technical solution: a corner structure for installing bridge steel formwork, including a mounting frame 1, a plurality of groups of adjusting assemblies 2 are installed at the bottom end of the mounting frame 1, and rotating assemblies 3 are installed on the lower sides of the adjusting assemblies 2. An inner formwork 11 is installed on the surfaces of the mounting frame 1 and the rotating assembly 3. The adjusting assembly 2 includes a movable groove 21, and the movable groove 21 is opened at the bottom end of the mounting frame 1. A movable rod 22 is slidably installed in the movable groove 21, and a plurality of limit grooves 23 are equidistantly opened at one end of the movable rod 22. A mounting hole 24 is opened in the inner wall of the movable rod 22, and a bolt 1 25 is inserted into the mounting hole 24. The bolt 1 25 passes through the mounting hole 24 and is inserted into the limit groove 23. This structure enables the device to be applicable to the construction operations of bridges with different heights, and better improves the applicability of the device. The rotating assembly 3 includes a first rotating rod 31, and the first rotating rod 31 is hinged at the bottom end of the movable rod 22. A chute 32 is opened at the top end of the first rotating rod 31, and a slide block 33 is slidably installed in the chute 32. A first connecting rod 34 is hinged on the upper side of the slide block 33. A support rod 35 is connected between the two first connecting rods 34, and the bottom end of the support rod 35 is connected to a support plate 36. This structure enables the angle of the inner formwork 11 to be adjusted as needed, so that the device can be applicable to the construction operations of bridges with different angles.

[0030] As an implementation manner in this embodiment, as Figure 2 and Figure 3As shown in the figure, a telescopic component 4 is installed between the rotating components 3 and the mounting frame 1. The telescopic component 4 includes a sleeve rod 41 and a driving component 5. The sleeve rod 41 is fixedly connected to the mounting frame 1. A threaded groove 42 is opened at the bottom end of the sleeve rod 41, and a screw rod 43 is rotatably installed in the threaded groove 42 through the driving component 5. The screw rod 43 is rotatably installed at the top end of the connecting rod 34 through the driving component 5. This structure makes it more convenient to adjust the angle of the rotating component 3 by adjusting the length of the telescopic component 4, and the operation is simpler and more convenient, greatly increasing the practicability of the device. The driving component 5 includes a mounting groove 51 and a locking component 6. The mounting groove 51 is opened on the upper side of the connecting rod 34. A main bevel gear 52 connected to the screw rod 43 is installed on the upper side of the mounting groove 51, and a secondary bevel gear 53 is engaged with one side of the main bevel gear 52. A connecting rod 54 is connected between the two secondary bevel gears 53. The connecting rod 54 is installed in the support rod 35. One end of a connecting rod 54 is connected to a connecting shaft 55, and a rotating rod 56 is installed at one end of the connecting shaft 55 through the locking component 6. This structure enables the simultaneous rotation of the two screw rods 43, so that the lengths of the two telescopic components 4 can be adjusted at one time, making it more convenient to adjust the angle.

[0031] As an implementation method in this embodiment, as Figure 4 and Figure 5 shown, the locking component 6 includes a fixed block 61. The fixed block 61 is fixedly connected to the surface of the connecting rod 34. A rotating groove 62 is opened at one end of the fixed block 61, and a rotating block 63 is rotatably installed in the rotating groove 62. The connecting shaft 55 and the rotating rod 56 are respectively connected to both ends of the rotating block 63. A handle 57 is installed at one end of the rotating rod 56 away from the rotating block 63, and anti-slip grooves are opened on the surface of the handle 57. This structure enables an increase in the friction force when contacting the handle 57, making it more convenient to drive the rotation of the rotating rod 56 through the handle 57. A nut 64 is embedded on one side of the fixed block 61, and a bolt 65 is threadedly inserted into the nut 64. The bolt 65 abuts against the rotating block 63. This structure enables the limitation of the rotation of the rotating rod 56, preventing accidental contact with the rotating rod 56 from driving the screw rod 43 to rotate and changing the length of the telescopic component 4, thereby affecting the adjusted angle. The end of the bolt 65 away from the rotating block 63 is connected to a knob 66 to make it more convenient to operate the rotation of the bolt 65.

[0032] Working principle: If it is necessary to adjust the length of the device, only need to pull the movable rod 22 to slide in the movable groove 21. When the length is adjusted, then pass the bolt 25 through the mounting hole 24 and rotate it into the appropriate limit groove 23 for fixation, greatly increasing the applicability of the device.

[0033] In addition, if it is necessary to adjust the angle of the device, simply hold the handle 57 and drive the second rotating rod 56 to rotate, so that the second rotating rod 56 drives the rotating block 63 to rotate in the rotating groove 62. The rotating block 63 drives the secondary bevel gear 53 to rotate through the connecting shaft 55. Through the connection of the second connecting rod 54, the two secondary bevel gears 53 rotate simultaneously. Through meshing, the secondary bevel gear 53 drives the main bevel gear 52 to rotate. The main bevel gear 52 drives the screw rod 43 to rotate in the threaded groove 42. Through screw rotation, the screw rod 43 can longitudinally move in the threaded groove 42, thereby adjusting the length of the telescopic assembly 4. At this time, the screw rod 43 will also drive the first connecting rod 34 to longitudinally move, so as to drive the first rotating rod 31 to rotate, making the angle between the first rotating rod 31 and the movable rod 22 change. At the same time, the angle between the first connecting rod 34 and the slider 33 will also change, and the slider 33 will slide in the sliding groove 32 until the first rotating rod 31 is adjusted to a suitable position. Finally, hold the knob 66 and drive the second bolt 65 to rotate in the nut 64 until the nut 64 abuts against the rotating block 63, and lock the rotating block 63 through friction. Although the thread can achieve self-locking, if the handle 57 is accidentally touched and the screw rod 43 rotates, the adjusted angle will still be changed. Therefore, locking the handle 57 can better maintain the adjusted angle, greatly increasing the practicability of the device.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
