Embodiment
[0016] Such as Figure 1-Figure 3 As shown, a fully prefabricated assembled bridge prevents the reverse installation of prefabricated components. It includes a prefabricated cover beam 1, a prefabricated column 2 and a cap 3, and the bottoms of the prefabricated cover beam 1 and prefabricated column 2 are near the symmetrical position (" The area other than the symmetrical position”, or the “asymmetrical position”) is respectively provided with embedded cylinders 4, and the top of the prefabricated column 2 corresponds to the position of the embedded cylinder 4 at the bottom of the prefabricated cover beam 1 and the position of the platform 3 Embedded cylinders 5 are respectively arranged at the positions where the top corresponds to the embedded cylinders 4 at the bottom of the prefabricated columns 2 .
[0017] Specifically, the pre-embedded cylinder 4 is a sleeve or a bellows
[0018] Specifically, the pre-embedded columns 5 are steel bars.
[0019] Specifically, only whe...

The invention discloses a pre-embedded structure for preventing reverse installation of prefabricated parts of a fully-prefabricated assembled bridge. The structure comprises a prefabricated bent cap,a prefabricated upright post and a bearing platform, and pre-embedded cylinders are respectively arranged near symmetrical positions at the bottoms of the prefabricated bent cap and the prefabricatedupright post; and embedded columns are arranged at the positions, corresponding to the embedded cylinders at the bottom of the prefabricated bent cap, of the top of the prefabricated upright post andthe positions, corresponding to the embedded cylinders at the bottom of the prefabricated upright post, of the top of the bearing platform respectively. The structure is simple, the embedded columnscan extend into the embedded cylinders in a one-to-one correspondence mode only when the assembling direction of the prefabricated bent cap, the prefabricated upright post and the bearing platform iscorrect, the embedded columns cannot be installed when the assembling direction is incorrect, and reverse installation of the prefabricated assembled bridge upright post and the bent cap is prevented.
Description
technical field [0001] The invention relates to the technical field of civil engineering, in particular to a pre-embedded structure for preventing reverse installation of components of a fully prefabricated assembled bridge. Background technique [0002] The cast-in-place caps and prefabricated columns of fully prefabricated assembled bridges are mostly symmetrical components, and the prefabricated columns are sometimes asymmetrical, and the prefabricated cap beams are mostly asymmetrical components. For prefabricated assembled bridges, the prefabricated columns are hoisted after the construction of the pile cap is completed, and then the prefabricated cap beams are hoisted. If there is a reverse installation during hoisting (such as: accidentally reversed when installing a cover beam above a symmetrical column), subsequent remedies will be very difficult. Will cause greater economic and construction period losses. [0003] Those skilled in the art are devoting themselves ...
