Description

Technical Field

[0001] This invention relates to the field of bridge engineering construction technology, and in particular to a support connection device. Background Technology

[0002] Bridge engineering refers to the processes of bridge surveying, design, construction, maintenance, and inspection. Regarding bridge construction materials, the main selection criteria are high strength, lightweight, and low cost, with continued development of traditional steel and concrete to improve their strength and durability.

[0003] For example, application number CN202310312537.0 discloses a bridge construction support device, relating to the field of bridge construction technology. This invention includes a support column installed on the ground and a support plate installed at the top of the support column and abutting against the bottom side of the bridge casting template. During construction, the bridge casting template is assembled according to the bridge's shape, and the support device supports the template during assembly. The support plate includes a base plate with four grooves evenly distributed on its upper surface, and metal movable plates are fitted into the grooves. This invention, by providing a support plate with four supporting metal movable plates at the top of the support column, achieves support for four bridge casting templates using the metal movable plates, solving the problem that existing steel pipes only support a single construction template; it also adapts to differences in the thickness of adjacent bridge casting templates or different support heights during actual construction.

[0004] When using existing support connection devices, the connecting parts in the device still use the traditional screw pressing and fixing technology. The assembly process is relatively complicated due to the large number of bolts, resulting in low assembly efficiency. Moreover, under the action of external forces or the vibration of the bridge itself, large gaps are easily generated between adjacent bridge pouring formwork. Although there are buffer auxiliary connection structures, the connection structure can still be damaged, which reduces the reliability of the connection support structure during use. Summary of the Invention

The limiting round rod is fitted with a buffer spring, which is supported between the connecting vertical frame and the guide sleeve b and the guide sleeve a. The corresponding connecting vertical frame is provided with a toothed plate, and the corresponding toothed plate is meshed with a gear.

[0012] Furthermore, the mounting frame has two limiting sleeves at the bottom, and the two limiting sleeves are symmetrically distributed. A rotating seat is provided in the middle of the mounting frame, and the rotating shaft is rotatably connected to the mounting frame through the rotating seat.

[0016] The support and connection device provided by the present invention has the following beneficial effects:

[0017] 1. This device is equipped with an elastic connecting frame. By snapping the connecting pipe fittings into the connecting sleeve frame, and simultaneously installing the elastic connecting frame between the first base and the second base, it can buffer the lateral prestress generated by the two bridge casting formworks, thereby improving the stability of the bridge casting formwork assembly and use. At the same time, the elastic buckle of the docking plug engages with the rectangular slots of docking sleeve a and docking sleeve b, enabling the elastic connecting frame to be assembled quickly.

[0018] 2. This device is equipped with an adjustment frame. The front and rear adjustment frames are matched and driven by relative toothed plates and gears. The elasticity of the buffer spring is used to make the relative adjustment frames slide to the sides or the middle at the same time. This can buffer the lateral force between the first base and the second base. At this time, no matter how much the external force swings or vibrates, it will not cause large gaps in the adjacent bridge casting formwork, thereby improving the reliability of the connection support structure.

[0019] 3. In this device, by manually pulling the control knob down along the spline axis, the ratchet sleeve and ratchet pawl are disengaged. Then, rotating the control knob clockwise drives the rotating shaft and swing frame to rotate. Through the cooperation of the transmission rod and the positioning rod, the positioning rod slides into the positioning slot, thereby limiting and fixing the first base and the second base. This allows for quick connection and assembly with the bridge casting template, eliminating the hassle of using bolts for connection and fixing, and further improving the assembly efficiency of this support connection structure.

[0050] The specific usage and function of this embodiment: In this invention, by snapping the connecting pipe 202 into the connecting sleeve 302, and simultaneously installing the elastic connecting frame 4 between the first base 2 and the second base 3, the lateral prestress generated by the two bridge casting templates 1 can be buffered, improving the stability of the bridge casting template 1 assembly and use. At the same time, the elastic buckle of the docking plug 401 engages with the rectangular slots of the docking sleeves a203 and b303, enabling the rapid assembly of the elastic connecting frame 4. The two adjusting frames 5 at the front and rear are matched, and the relative toothed plates 504 and gears 406 are driven, and the elastic action of the buffer spring 503 is used to make the relative adjusting frames 5 simultaneously move towards the two sides. The side or center sliding adjustment can buffer the lateral force between the first base 2 and the second base 3. At this time, no matter how much the external force swings or vibrates, it will not cause a large gap in the adjacent bridge casting template 1. By manually pulling the control knob 9 down along the spline shaft 704, the ratchet sleeve 902 and the ratchet pawl 802 are disengaged. Then, by rotating the control knob 9 clockwise, the rotating shaft 7 and the swing frame 701 can be driven to rotate. Through the cooperation of the transmission rod 702 and the positioning rod 703, the positioning rod 703 is slidably inserted into the positioning slot 102, thereby limiting and fixing the first base 2 and the second base 3, which can be quickly connected and assembled with the bridge casting template 1.
