Problems solved by technology

[0007] The invention provides a jack balance device and a mobile formwork used for a mobile formwork to solve the problem of uneven force on the double-top support caused by the influence of the disturbance of the main beam itself on the middle legs of the existing mobile formwork. High costs are required to reduce risks; the support force is unevenly transmitted to the bottom, resulting in eccentric loads on the support force on the middle leg, which is prone to construction safety problems and construction quality problems

Abstract

The invention discloses a jack balancing device used for a movable formwork. The jack balancing device comprises multiple balance beams parallel to the longitudinal axis of a main beam of the movable formwork. The multiple balance beams are erected on supporting leg units, on the two sides of the main beam, of middle supporting legs of the movable formwork. Balance mechanisms used for applying the vertical acting force in a balanced manner and conducting stress deviation control are arranged between the balance beams and the main beam. The balance mechanisms can conduct stress deviation control on the received counter acting force fed back by the main beam while applying the vertical acting force, and the supporting force unbalance loading problem caused by deflection of the main beam is solved; and the middle supporting legs can be stressed in a balanced manner, and therefore the safety and the construction quality of the whole device are guaranteed.

Description

technical field [0001] The invention relates to the technical field of bridge construction moulds, in particular to a jack balancing device for moving a mold base. In addition, the present invention also relates to a mobile formwork comprising the above-mentioned jack balancing device for the mobile formwork. Background technique [0002] With the development of my country's transportation industry, the construction methods of the bridge superstructure are becoming more and more diverse. In the environment where the traditional support is not suitable, the construction scheme of the mobile formwork has the advantages of low amortized cost of multi-span construction, little impact on the environment without steel pipe support, and low environmental impact. It has the advantages of small on-site factor constraints and short single-span construction period. [0003] The mobile formwork is a self-propelled special equipment for bridge construction with its own formwork, supporte...
