Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a quick-detachable bracket for a cast-in-situ cap beam of a widening bridge in a river channel. Background Art

[0002] Before pouring the bridge cap beam for widening the river channel, a bracket is needed to support the pouring formwork. The existing patent is a single-column pier double-hoop cap beam bracket, patent announcement number CN220352627U, including a pier, a bridge body is arranged at the top of the pier, symmetrically distributed I-type plates are fixedly installed on both sides of the bottom of the bridge body, and four symmetrically distributed fixed plates are fixedly installed on the side where the two I-type plates are close to each other, two symmetrically distributed first double hoops are arranged on the top of the pier, and two symmetrically distributed second double hoops are arranged at the bottom of the pier. Two symmetrically distributed mounting plates are fixedly installed on both sides of the first double hoop and the second double hoop close to the second connecting plate. The utility model is provided with a force unloading rod, a spring and a fixed block. When the bridge body is subjected to pressure, it will be transmitted to the fixed frame through the spring, so that the pressure is shared by the second double hoop, so that the bearing capacity of the bridge body is increased and the overturning situation is reduced. The diagonal bracing beam is arranged so that the bridge body can be more stable and the force of the bridge body is increased, thereby making the bridge body more stable.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: during the actual installation process, the clamp of the bracket is still installed by the most primitive bolts, which requires carrying multiple bolts and nuts in a high-altitude environment and using professional tools to operate.

Then, the rotating block 308 is rotated to drive the bidirectional lead screw 304 to rotate. The rotation of the bidirectional lead screw 304 drives the two slide bars 305 to move to both sides at the same time, thereby driving the positioning column 306 on the slide bar 305 to be inserted into the connecting groove 302 on the connecting strip 301, thereby achieving effective positioning of the connecting strip 301, and then achieving effective fixation between the first top plate 103 and the second top plate 104, thereby ensuring the stability of the bracket when in use.
