Abstract

The invention discloses a road and bridge steel form demoulding device. The device comprises a machine body placed on a bridge body; two hydraulic cylinders are symmetrically and fixedly installed onthe two sides of the machine body; a right-angle rod is inserted into each hydraulic cylinder in a sealed mode; a demoulding unit is installed at the lower end of each right-angle rod; and a hydrauliccontrol system is installed on the machine body. According to the demoulding device of the invention, a plurality of demolding piston rods are inserted into a plurality of dismounting holes, so thatdemolding can be carried out through a hydraulic control system; excessive manpower is not needed; workload and danger are reduced; the strength of the right-angle rods is improved through protectionrods, so that the safety of the device is improved; independent control over the movement of the right-angle rods and the stretching and retracting of the demolding piston rods is achieved through electromagnetic reversing valves, and the demoulding convenience of the device is improved.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to an ejection device for road and bridge steel formwork. Background technique [0002] At present, with the rapid development of modernization, every city is building roads and bridges to increase the convenience of transportation in the city, thereby driving the economic development of the city. The construction of roads and bridges is inseparable from formwork support. Formwork, commonly used formwork materials include plastic, wood and steel plates. Due to the low strength of plastics, there are few occasions for use. Wooden plates are perishable, resulting in increased consumption and increased costs. Therefore, the use of formwork is becoming less and less. Strong corrosion resistance, high strength, and high reusability are used in the production of formwork in various fields, especially in the construction of roads and bridges. Bridge piers, bridge bodies, and road surfaces a...
