Embodiment Construction

[0033] The traveling vehicle frame 1 of the mobile integral construction platform shown in Fig. 1 includes two horizontal longitudinal beams 2 and a horizontal crossbeam 3 fixedly connected between the two horizontal longitudinal beams, and a traveling wheel 9 is arranged under the two horizontal longitudinal beams And the running track 10 that cooperates with the running wheel 9; Gauge pull rod 11 is set between the running tracks; Locking parts are set on the running wheel. The longitudinal beam is 16# double channel steel, the crossbeam is 14# double channel steel, and the running track is 10# small channel steel.

[0034] As shown in Figures 2 and 3: the traveling hanger 4 of the mobile integrated construction platform includes an upright main frame 5 and a horizontal hanger 6 mounted on the bottom of the main frame; Longitudinal beam (3) is a pair of hanger platforms (7) that are arranged horizontally and parallel to each other orthogonally, and the pier platform (8) that...

Abstract

The invention relates to a mobile type integrated construction platform, and a method for using the mobile type integrated construction platform in a wet tie-in which is spanned with a box beam to construct and an outer side template dedicated hanger used in the method of carrying out the wet tie-in construction. The mobile type integrated construction platform comprises a running frame and a running hanging rack which is fixedly connected with the lower part of the running frame; the upper end face of the main frame of the running hanging rack is fixedly connected with the beam of the running frame; the lower end face of the main frame is fixedly connected with the hanging rack; the front part and the rear part of the hanging rack are respectively provided with a hanging rack platform; the two ends of the hanging rack platform are respectively hinged with a side abutment platform. A sturdy and firm temporary construction platform can be formed by the hanging rack platforms and the side abutment platforms by adopting the mobile type integrated construction platform and the method of applying the mobile type integrated construction platform in the wet tie-in which is spanned with a box beam to construct. The side abutment platforms are dropped after the construction; then the mobile type integrated construction platform can be longitudinally moved to a next working face without repeatedly building and dismounting the construction platform, thus greatly reducing the work load of the construction and providing reliable guarantee to the construction safety.

Description

technical field [0001] The invention relates to a mobile overall construction platform used in the construction of bridge system conversion wet joints, a method for using the platform to construct wet joints for erecting box girders, and a special spreader for outer formwork used in the construction method. Background technique [0002] At present, in domestic bridge construction, during the process of adopting simply supported box girder first and then converting it into a continuous box girder, in order to adjust the joint error and reduce the difficulty of assembly, a wet joint construction method is used between two adjacent girder piers. Usually, a simple scaffolding construction platform is built on the top of the pier first, and then the upper and lower platform channels are built after the beam erection is completed, the construction platform is reinforced, and then the wet joint formwork is installed, and the wet joint concrete is poured, and then the wet joint concr...
