Description

Technical Field

[0001] The utility model relates to the technical field of induced joint structures, in particular to an induced joint structure for a frame bridge. Background Art

[0002] During the jacking construction of a frame, if the length of the jacked frame is relatively long, it is usually precast in multiple sections and then jacked using the relay jack method. This requires a long construction period, and the cumulative jacking deviation increases after the number of jacking operations increases; or the frame is precast in one piece throughout its length. Although this can shorten the construction period, the frame structure will have more cracks due to the influence of concrete stress, and the quality cannot be guaranteed. In the past, a settlement joint was set every about 5 - 10 m on the frame. According to the publication number: CN202830739U, an induced joint structure for a frame bridge is disclosed, which is an induced joint structure set in a frame bridge to improve the concrete stress cracks in the long box jacking frame and the water seepage phenomenon at the frame joint, belonging to the technical field of jacking construction. It includes an induced joint set in the frame bridge, a caulking plate (7) is arranged in the induced joint, and a number of steel shear pins (5) arranged along the frame length direction are spaced along the frame height direction in the side walls on both sides of the frame at the induced joint. The steel shear pins (5) pass through the caulking plate (7), and waterproof layers are respectively arranged on the outer side of the top plate, the outer sides of the side walls on both sides, and the inner side of the frame at the induced joint. The structure of the utility model is simple, can effectively improve the phenomenon that the frame structure has more cracks due to the influence of concrete stress, greatly reduce the cumulative jacking deviation generated by the multi - section frame jacking in multiple times, improve the project quality, and can greatly shorten the construction period and reduce the construction cost. However, the above - mentioned technology still has some defects. For example, since the existing induced structure of the frame bridge does not have a shielding structure, it is necessary to use a shielding board to additionally fix the concrete during use, and the practicability is poor and needs to be improved.

Then, pick up the baffle 9 with the pinch plate 10, align it with the upper chute 8 and press it down. When the baffle 9 drives the sealing gasket 11 to completely slide into the frame body 2 through the chute 8, and at this time the pinch plate 10 is firmly stuck in the middle of the frame body 2. Then pinch the clamping rod 13 to align it with the fixing groove B12 and press it inward, so that the clamping rod 13 completely slides into the baffle 9 and the frame body 2 through the fixing groove B12 and the fixing groove A7. Then, secondary pouring can be carried out through the caulking groove 6 to join the frame bodies 2 together. And during the use process, the overall strength of the structure is improved.
