Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to an assembled hanging basket rapid maintenance construction platform. Background Art

[0002] The bridge construction hanging basket is a device used for cantilever casting of concrete bridges. The construction hanging baskets used in the cantilever casting construction of prestressed concrete continuous beams (rigid frame beams) in my country mostly adopt functional designs. As long as the strength, rigidity, stability and deadweight limit requirements of the structure are met, it is an open hanging basket, and safety protection is limited to conventional guardrails and protective nets. The removal of the hanging basket requires on-site dismantling of the entire structure.

[0003] After searching, a Chinese patent disclosed a hanging basket safety protection system device for bridge construction (authorization announcement number CN201071487Y), including a high-altitude falling object prevention device, which is a dense mesh steel wire mesh enclosed along the four sides of the hanging basket. The bottom and surrounding areas of the hanging basket are provided with an insulation device, the bottom of the hanging basket is provided with a waterproof device, and one end of the main beam of the hanging basket is provided with a lightning protection device. Although this patented technology adopts the hanging basket safety protection system device of this utility model, it can provide comprehensive safety protection for structures and construction personnel during bridge construction, effectively improving the construction progress.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that most of the bridge construction currently uses a one-piece hanging basket, and the on-site construction is carried out as a whole. However, the one-piece hanging basket structure causes its entire skeleton to be larger, which increases the floor space occupied during the transportation process. In addition, the overall lifting method has a high difficulty coefficient and the lifting process is unstable, which greatly increases the unstable factors in the construction process. Utility Model Content

[0005] In view of the above problems existing in the prior art, the main purpose of the present invention is to provide an assembled hanging basket rapid maintenance construction platform.

[0010] As a preferred embodiment, tracks are provided at both ends of the top of the pier formwork, the bottom ends of the tracks are fixedly connected with pad beams at equal distances, second anchor rods are provided inside the pad beams, and the pier formwork and the pad beams are connected via the second anchor rods.

[0015] By adopting the above technical solution and setting up the prestressed frame, the prestress of the track can be increased to improve the longitudinal resistance of the track.

[0016] As a preferred embodiment, bottom templates are spot-welded between the tops of the plurality of bottom longitudinal beams, and the main trusses are fixedly mounted on the outsides of the corresponding rails.

The bottom formwork is spot-welded on multiple bottom longitudinal beams to ensure the stability of the contact surface of the construction workers' feet. Compared with the traditional one-piece hanging basket, this solution splits the entire hanging basket into: rear lower cross beam, front lower cross beam, bottom longitudinal beam and bottom formwork, which can reduce the instability of the overall lifting, and at the same time can reduce the floor space occupied during transportation, making consignment more convenient.

[0034] Working principle: First, clean the area above the bridge 1 and install the track 3. By setting the second anchor rod 18, multiple cushion beams 4 can be installed above the pier formwork 2 to fix the track 3, thereby providing strong support for the main trusses 6. Then, the main trusses 6 are installed above the corresponding tracks 3, and the transverse connecting trusses 9 and the front upper crossbeam 8 are welded between the two main trusses 6.

[0035] Then, the third anchor rod is used to install the rear lower cross beam 14 under the pier formwork 2, and the rear hanger 15 is used to increase the overall stability and support performance of the rear lower cross beam 14. At the same time, the rear hanger 15 is used to connect the rear lower cross beam 14 with the transverse connecting truss 9 and the pier formwork 2.
