Problems solved by technology

The shortcomings of the conventional self-propelled method of the mobile formwork are: the lateral movement of the bottom formwork system requires more lateral movement equipment, high cost, and many processes; the legs of the mobile formwork cannot be self-propelled, and other lifting equipment must be cooperated Increased costs, when the site terrain conditions are poor and the lifting equipment is difficult to use, the transfer of the outriggers becomes the bottleneck of the construction of the mobile formwork; the formwork of the mobile formwork needs to be adjusted piece by piece in each construction cycle, and the workload is heavy , high quality dispersion of finished beams

Abstract

The invention discloses a downlink movable mould frame and a walking method thereof. The downlink movable mould frame comprises a girder, a guide beam connected at two ends of the girder and a mould frame system arranged on the girder. The downlink movable mould frame is characterized in that: three groups of legs are arranged below the girder; the leg comprises a middle leg and a rear leg arranged at the front end and rear end of the girder; the front guide beam is closed to the front leg arranged below the girder; a longitudinal and transverse beam system of the leg, the girder and the guidebeam and a lifter of the girder and the guide beam are arranged between the middle leg the rear leg, the front leg and the girder and the guide beam. The invention realizes walking automation of themovable mould frame and needs no extra cranes so as to strengthen the adaptability of the movable mound frame and enhance the economic competitiveness; the girder carries the external template to movetransversely so that the transverse devices of the templates are reduced, and the amount of the transverse oil cylinders of the total set of movable mould frames is reduced by above 60percent; the invention realizes demoulding and mould closing integrally without regulating templates one by one, thereby reducing the labour amount, simplifying the procedure and greatly improving the degree of mechanization.

Description

technical field [0001] The invention belongs to bridge construction technology, and in particular relates to a mobile box girder construction formwork and a running method of the mobile box girder construction formwork during the construction of a bridge engineering superstructure box girder. Background technique [0002] The mobile formwork can be divided into two types according to the location of its running mechanism. The traveling mechanism is located above the concrete box girder, which is called the upward moving formwork, and the running mechanism is located below the concrete box girder, which is called the downward moving formwork. Mobile formwork is a kind of box girder cast-in-place equipment that can be self-propelled, and its self-propelled method and efficiency have always attracted people's attention. The walking of the mobile formwork includes the vertical movement, lateral movement and lifting of the formwork. The longitudinal movement is to move the mobil...
